Background and Objectives: Parkinson disease (PD), which is a neurodegenerative disorder, includes several gastrointestinal symptoms that are similar to those of Celiac disease (CD). However, the presence of celiac antibodies in PD patients has not yet been studied. Our aim in this study is to compare anti-transglutaminase (ATA) and antigliadin antibodies (AGA) as well as gastrointestinal symptoms and nutrition habits between patients with Parkinson's disease (PD) and healthy controls. Methods and Study Design: Serum AGA IgG and IgA and the ATA antibodies IgA and IgG were studied in 102 PD patients and 91 healthy controls. Gastrointestinal symptoms, specifically constipation, were investigated using the gastrointestinal system rating scale (GSRS) and the constipation rating scale (CRS). Dietary habits were also investigated and compared between the groups. Results: No significant differences were found between the two groups in terms of celiac antibodies. As expected, the hypokinetic GSRS and CRS scores were significantly higher in the PD group (p<0.001). Dietary habits, especially carbohydrate-rich diets, had a negative impact on gastrointestinal symptoms in the PD patients. Conclusions: Studies have suggested a connection between PD and CD, which infers a probable non-celiac gluten intolerance and the need to offer PD patients an elimination diet. However, the results of our study did not support any link between celiac antibodies and PD. Notwithstanding, the negative impact of a carbohydrate-rich diet in PD patients still leaves a question regarding gluten sensitivity in these patients. [ABSTRACT FROM AUTHOR]

Postural orthostatic tachycardia syndrome (POTS) is characterized by exaggerated orthostatic tachycardia in the absence of orthostatic hypotension. The pathophysiology of POTS may involve hypovolemia, autonomic neuropathy, a hyperadrenergic state, and cardiovascular deconditioning, any of which can co-occur in the same patient. Furthermore, there is growing evidence of the role of autoimmunity in a subset of POTS cases. In recent years, investigators have described an increased rate of autoimmune comorbidities as evidenced by the finding of several types of neural receptor autoantibody and non-specific autoimmune marker in patients with POTS. In particular, the association of the disease with several types of anti-G protein-coupled receptor (GPCR) antibodies and POTS has frequently been noted. A previous study reported that autoantibodies to muscarinic AChRs may play an important role in POTS with persistent, gastrointestinal symptoms. To date, POTS is recognized as one of the sequelae of coronavirus disease 2019 (COVID-19) and its frequency and pathogenesis are still largely unknown. Multiple autoantibody types occur in COVID-related, autonomic disorders, suggesting the presence of autoimmune pathology in these disorders. Herein, we review the association of anti-GPCR autoantibodies with disorders of the autonomic nervous system, in particular POTS, and provide a new perspective for understanding POTS-related autoimmunity.

The purpose of this study was to examine the relation of mobility with abdominal symptoms and pain in patients undergoing abdominal surgery. The study has a prospective, correlational design. The study sample included 130 patients who underwent abdominal surgery. Data were gathered with a sociodemographic and clinical features form, the Patient and Observer Mobility Scale, a patient mobility checklist, the Gastrointestinal Symptom Rating Scale, and the Numeric Pain Rating Scale. Higher scores on the Gastrointestinal Symptom Rating Scale show more severe symptoms (max scores: 21 on abdominal pain, 14 on reflux, 21 on diarrhea, 28 on distension, and 21 on constipation). The frequency of mobility and the severity of pain was evaluated from the postoperative first day until discharge. Gastrointestinal symptoms were evaluated on the postoperative seventh day. The mean time elapsing till the first postoperative mobility was 22.13 ± 0.57 hours. The mean score was 7.61 ± 0.19 on abdominal pain, 11.94 ± 0.23 on distension, 2.04 ± 0.32 on reflux, 5.02 ± 0.32 on diarrhea, and 4.65 ± 0.24 on constipation. As the difficulty in mobility increased, the frequency of patient mobility decreased, and pain severity increased. As the difficulty in mobility increased, so did the duration of abdominal pain, diarrhea, indigestion, reflux, and time elapsing until the first intestinal gas passed after surgery. As the frequency of mobility increased, abdominal pain, diarrhea, and time elapsing till the first intestinal gas after surgery decreased. The results of the study showed that increased mobility had a positive relationship with the reduction of gastrointestinal symptoms and pain. Therefore, interventions directed toward increasing patient mobility should be performed. [ABSTRACT FROM AUTHOR]

Introduction: Gastrointestinal symptoms as well as depression and anxiety can negatively affect the effectiveness of military training and combat in general. This cross-sectional study aimed to determine the prevalence of gastrointestinal symptoms in recruits and further validate their associations with depression and anxiety. Methods: A self-report questionnaire was sent to the recruits in an army in April 2022, which primarily included the Symptom Rating Scale (GSRS) for the assessment of gastrointestinal symptoms, the Bristol Stool Scale (BSS) for stool consistency and shape, the Patient Health Questionnaire-9 (PHQ-9) for depression, and the 7-item Generalized Anxiety Disorder scale (GAD-7) for anxiety. Correlation of gastrointestinal symptoms with depression and anxiety was evaluated. Results: Overall, 467 recruits were included. Their median age was 21.0 years old (range: 18.0–24.0), and 98.1% of them were male. The proportion of gastrointestinal symptoms, abnormal stools, depression, and anxiety was 69.2% (n = 323), 11.3% (n = 53), 17.6% (n = 82), and 12.2% (n = 57), respectively. The recruits with gastrointestinal symptoms evaluated by GSRS had significantly higher prevalence of depression (P < 0.001) and anxiety (P < 0.001) than those without. GSRS score positively correlated with PHQ-9 (rs = 0.440, P < 0.001) and GAD-7 score (rs = 0.386, P < 0.001). Conclusion: Gastrointestinal symptoms are very common in recruits, and positively correlate with depression and anxiety. [ABSTRACT FROM AUTHOR]

This study aimed to develop and assess the reliability, validity, and sensitivity of the Japanese version of the University of California Los Angeles Scleroderma Clinical Trial Consortium gastrointestinal tract (GIT) Instrument 2.0 (the GIT score), as an evaluation tool for GIT symptoms in systemic sclerosis (SSc). The Japanese version of the GIT score was constructed using the forward‐backward method. The reliability and validity of this instrument were evaluated in a cohort of 38 SSc patients. Correlation analysis was conducted to assess the relationship between the GIT score and existing patient‐reported outcome measures. Additionally, the sensitivity of the GIT score was examined by comparing GIT scores before and after intravenous immunoglobulin (IVIG) administration in 10 SSc‐myositis overlap patients, as IVIG has recently demonstrated effectiveness in alleviating GIT symptoms of SSc. As a result, the Japanese version of the GIT score exhibited internal consistency and a significant association with the Frequency Scale for the Symptoms of Gastroesophageal Reflux Disease. Furthermore, the total GIT score, as well as the reflux and distention/bloating subscales, displayed moderate correlations with the EuroQol 5 dimensions (EQ‐5D) pain/discomfort subscale and the Short Form‐36 body pain subscale. Notably, following IVIG treatment, there was a statistically significant reduction in the total GIT score and multiple subscales. We first validated the Japanese version of the GIT score in Japanese SSc patients in real‐world clinical settings. This instrument holds promise for application in future clinical trials involving this patient population. [ABSTRACT FROM AUTHOR]

Background: Due to the long hospitalization periods in internal medicine services, there are increases in the gastrointestinal problems based on several reasons such as weakness in muscles, blunting in defecation desire, the use of disposable underpads or bedpans, having difficulty to express defecation desire, change in eating habits, medications, and increase in symptoms Aims: This study was conducted to investigate the effect of the gastrointestinal symptoms on the quality of life of individuals. Methods: The descriptive study was conducted in the City Hospital in Turkiye by employing the individuals hospitalized in internal medicine services between November 2019 and April 2020 (n= 500). The data were obtained through the Patient Information Form, Gastrointestinal Symptom Rating Scale (GSRS), and SF-36 Quality of Life Scale. Results: In our study, 2,4% of the change in the abdominal pain score was resulted from pain and general health. It was seen that 1,4% of the change on the reflux score was due to the pain variable. A negative low relationship was found between the diarrhea symptom rate of the individuals and their health and physical functions as well as between reflux symptom rate and pain. It was further found that the quality of life of individuals was at moderate level, and gastrointestinal symptoms reduced the quality of life. Conclusions: It is recommended that nursing care plans should be prepared and consultancy should be regularly provided to decrease the gastrointestinal symptoms of the individuals in the risk group.

Background: Research on whether gastrointestinal symptoms correlate with the severity of Coronavirus Disease 2019 (COVID-19) has been inconclusive. This study aimed to clarify any associations between gastrointestinal symptoms and the prognosis of COVID-19. Methods: We collected data from the Japanese nationwide registry for COVID-19 to conduct a retrospective cohort study. Data from 3498 Japanese COVID-19 patients, diagnosed at 74 facilities between February 2020 and August 2022, were analyzed in this study. Hospitalized patients were followed up until discharge or transfer to another hospital. Outpatients were observed until the end of treatment. Associations between gastrointestinal symptoms and clinical outcomes were investigated using multivariable-adjusted logistic regression models. Results: The prevalence of diarrhea, nausea/vomiting, abdominal pain, and melena were 16.6% (581/3498), 8.9% (311/3498), 3.5% (121/3498), and 0.7% (23/3498), respectively. In the univariable analysis, admission to intensive care unit (ICU) and requirement for mechanical ventilation were less common in patients with diarrhea than those without (ICU, 15.7% vs. 20.6% (p = 0.006); mechanical ventilation, 7.9% vs. 11.4% (p = 0.013)). In the multivariable-adjusted analysis, diarrhea was associated with lower likelihood of ICU admission (adjusted odds ratio (aOR), 0.70; 95% confidence interval (CI), 0.53–0.92) and mechanical ventilation (aOR, 0.61; 95% CI, 0.42–0.89). Similar results were obtained in a sensitivity analysis with another logistic regression model that adjusted for 14 possible covariates with diarrhea (ICU; aOR, 0.70; 95% CI, 0.53–0.93; mechanical ventilation; aOR 0.62; 95% CI, 0.42–0.92). Conclusions: Diarrhea was associated with better clinical outcomes in COVID-19 patients. [ABSTRACT FROM AUTHOR]

Endometriosis is an estrogen-dependent chronic disease characterized by the presence of endometriumlike tissue outside the uterus and is often associated with symptoms, such as dysmenorrhea, dysuria, dyschezia, chronic pelvic pain, and infertility. Moreover, women diagnosed with endometriosis can report gastrointestinal symptoms, including bloating, constipation or diarrhea, and abdominal cramping, which can be associated with irritable bowel syndrome and can result in the misdiagnosis of endometriosis as irritable bowel syndrome at first. Treatment usually involves hormonal therapy, pain management, surgery, and/or assisted reproductive techniques in case of infertility. Nonetheless, these treatment methods can be insufficient for alleviating symptoms or can have unacceptable side effects, leading to noncompliance. Therefore, women often apply self-management strategies, including dietary interventions.One of the diets frequently suggested as a tool to manage endometriosis-related symptoms on social media and patient forums is a gluten-free diet. Although a gluten-free diet has been proven effective in managing nonceliac wheat sensitivity or celiac disease, its effectiveness in endometriosis remains uncertain. The Nurses’ Health Study II found it unlikely that gluten intake was a strong factor in endometriosis etiology and symptomatology. To the best of our knowledge, the most frequently cited and sole published intervention study on the efficacy of a gluten-free diet for endometriosis has several important limiting factors, including the absence of a control group. In addition, gluten consumption is highly susceptible to a placebo effect and a nocebo effect, where women might experience symptom relief after eliminating gluten and return of symptoms after they consume gluten again, solely because they believe that gluten is bad for them. Despite the inverse association between body mass index and endometriosis and between a gluten-free diet and increased body mass index, this is an association, and no causality was proven. In addition, other factors should be taken into consideration.Of note, a gluten-free diet is expensive, has limited availability, and has a significant effect on quality of life. Moreover, without proper dietary guidance, it may adversely affect the gastrointestinal microbiome. Therefore, scientifically substantiated advice regarding the use of a gluten-free diet for endometriosis-related symptoms is currently not available, and a gluten-free diet should be discouraged unless there is an additional diagnosis of nonceliac wheat sensitivity or celiac disease.

Background: Gastrointestinal symptoms are prevalent amongst patients with a confirmed diagnosis of COVID-19 and may be associated with an increased risk of disease severity. This trial aimed to evaluate the efficacy and safety of aniseed (Pimpinella anisum L.) powder as an add-on therapy to standard care for treating gastrointestinal symptoms experienced by adults with an acute SARS-CoV-2 infection. Methods: The study was a randomized parallel-group double-blinded placebocontrolled add-on therapy trial. Adults with an acute SARS-CoV-2 infection who did not require hospitalization and reported at least one gastrointestinal symptom in the preceding 48 h were assigned to either the aniseed or placebo group in a 1:4 ratio. All 225 participants (45 in the aniseed group and 180 in the placebo group) were instructed to use 25 g of powdered aniseed or placebo twice daily for 2 weeks. The primary outcomes were the proportion of patients who experienced an improvement of at least one point in the symptom score after adjusting for age group, gender, and time. Backwards stepwise logistic regression was applied to calculate the risk ratios. The clinical symptoms and adverse events were assessed at the beginning, 1 week later, and at the end of the trial (week two). Results: Participants in the aniseed group were significantly more likely to report symptom improvement for abdominal pain [adjusted risk ratio (RR):0.55; 95% confidence interval (CI): 0.46--0.72], anorexia (RR:0.62; 95% CI: 0.47--0.82), and diarrhea (RR:0.19; 95% CI: 0.12--0.30), but not nausea/vomiting (RR:0.87; 95% CI: 0.71--1.08) or bloating (RR:0.87; 95% CI: 0.72--1.05). Two participants in the aniseed group and three participants in the placebo group reported mild to moderate adverse events. Conclusion: This study showed that 2 weeks of aniseed powder containing transanethole (87%--94%) may help improve abdominal pain, anorexia, and diarrhea in COVID-19 patients. The findings align with the known biological, multitargeted activity of P. anisum and trans-anethole, which includes inhibiting SARS-CoV- 2 along with other anti-infective, anti-inflammatory, antioxidant, hepatoprotective, and anti-dysbiosis properties. Multicenter trials with larger sample sizes and longer follow-up are warranted to confirm these findings. [ABSTRACT FROM AUTHOR]

L-Arg is a nonessential amino acid but has many physiological roles. Accordingly, L-Arg has been used in various fields, but there is only limited information available about its safety upon overdose. Generally, the no-observed adverse effect level (NOAEL) is used when setting the upper amount for chemical substances. Recently, systematic reviews have been used to assess the safety as well as the effectiveness and usefulness of them. Therefore, we conducted an assessment of the safety of the oral intake of L-Arg in healthy subjects using gastrointestinal symptoms as an index. We limited the study design to only double-blind randomized controlled trials and searched PubMed, Cochrane Library, EBSCOhost, and Ichushi-Web from inception until May 2021. Assessment of the quality of studies was conducted using the Cochrane Collaboration tool and Jadad score, and the random effects model was used for data analysis. Ultimately, 34 studies were selected for inclusion in this work. The dosage of L-Arg used in the studies ranged from 2000 to 30,000 mg/day (or/one-time dose), and the treatment duration was 1–84 days. The increased risk of gastrointestinal symptoms associated with L-Arg intake from 23 studies (647 participants in total) in which such symptoms were reported was 0.01 (95% confidence interval: – 0.02–0.04), which was not significant difference. NOAEL was estimated as 7531 mg/ one-time dose using a weighted change-point regression model (UMIN000046133). Registration and protocol: Umin.ac.jp as UMIN000046133. [ABSTRACT FROM AUTHOR]

GI symptoms are common in acute COVID-19 patients. This study aimed to characterize the GI symptoms occurring in Japanese COVID-19 patients. This retrospective single-center cohort study included 751 hospitalized acute COVID-19 patients. The primary outcomes were the frequency and severity of GI symptoms. The secondary outcomes included the association between COVID-19 severity and GI symptoms and the timing of GI symptom onset. After exclusion, the data of 609 patients were analyzed. The median age was 62 years, and 55% were male. The median time from initial symptom onset to admission was five days. On admission, 92% of the patients had fever, 35.1% had fatigue, 75% had respiratory symptoms, and 75% had pneumonia. The sample included patients with mild (19%), moderate (59%), and severe COVID-19 (22%). A total of 218 patients (36%) had GI symptoms, of which 93% were classified as grade 1/2; 170 patients had both respiratory and GI symptoms. Diarrhea was the most frequent GI symptom, occurring in 170 patients, followed by anorexia in 73 patients and nausea/vomiting in 36 patients, and abdominal pain in 8 patients. There was no significant relationship between COVID-19 severity and GI symptoms. Among COVID-19 patients with both GI and respiratory symptoms, 48% had respiratory symptoms preceding GI symptoms, 25% had GI symptoms preceding respiratory symptoms and 27% had a simultaneous onset of respiratory and GI symptoms. Thirty-six percent of the Japanese COVID-19 patients had GI symptoms; diarrhea was the most frequent GI symptom but did not predict severe COVID-19. [ABSTRACT FROM AUTHOR]

Background: Digestive symptoms and gastrointestinal issues in children with coronavirus 2019 disease (COVID-19) and Multisystem Inflammatory Syndrome in Children (MIS-C) are commonly reported in pediatric studies from different countries. Our retrospective observational study aimed to summarize the main digestive symptoms and objective data on gastrointestinal involvement in children with MIS-C. Methods: We present the clinical, laboratory, and imaging data of 51 children with MIS-C hospitalized in a single center from 25 November 2020 to 24 April 2021, focusing on gastrointestinal involvement. Results: A total of 46/51 children (90.2%) reported at least one abdominal symptom (abdominal pain (86%, N = 44), vomiting, nausea, diarrhea), predominantly at presentation. Most children were older than 5 years (N = 40, 78%), predominated by the male sex (N = 37, 72.5%), and with a mean age of 8.82 x 4.16 years. We found a tendency for lymphopenia, neutrophilia, and higher levels of CRP, d-dimer, and ferritin in MIS-C patients with abdominal pain (R-squared 0.188, F-statistic vs. constant model: 11.9, p-value = 0.00122, 20% explanation of variation with p = 0.001). We found a statistically significant linear relationship (regression) between neutrophile percentage (NEU%) and hospital stay and a tendency for elevated transaminases to be more frequent in older children (27.3% under 5 years and 65% over 5 years; p = 0.0583). We found no significant associations between digestive symptoms and age or the predominant SARS-CoV-2 variant. Conclusions: Most of our MIS-C patients presented with abdominal pain, usually along with other GI symptoms, which could be applied in clinical practice to MIS-C in children visiting the emergency room with abdominal pain and evidence of recent COVID-19 contact or infection. Further information from larger cohorts of MIS-C patients is needed to better understand the epidemiology of gastrointestinal involvement in these patients. [ABSTRACT FROM AUTHOR]

Background The emergence of the coronavirus disease (COVID-19), created unique constraints in everyday life. Emotional eating is a known phenomenon in disasters and is markedly associated with gastrointestinal symptoms. In this study, the aim was to assess the relationship of gastrointestinal symptom severity and COVID-19 burnout with emotional eating among young women during the pandemic disaster. Methods A cross-sectional study approach was used to allow 462 young women participants in this study. The design of the questionnaires was based on demographics, health behaviors, Gastrointestinal Symptom Severity Scale, Emotional Eating Scale and COVID-19 Burnout Scale. Data were analyzed using percentages, mean values, independent t-test, chi-squared test. The hierarchical multiple regression analysis was performed for predicting risk factors of emotional eating. Significance levels were set at the 5% level. Results Of the women, 73.8% were emotional eaters. The level of COVID-19 burnout was moderate with mean score of 29.4±11.1 and emotional eating total score was 21.0±8.1. Increased number of meals, increased weight gain and shorter sleep time were significantly associated with emotional eating (p

The purpose of this secondary analysis was to determine the clusters of midlife women by gastrointestinal (GI) symptoms and to explore differences in the clusters by race/ethnicity. This analysis used the data from two internet-based studies among 1,054 midlife women. The analysis was conducted with the data on background characteristics, health and menopausal status, and GI symptoms (collected using the GI Symptom Index for Midlife Women). The data were analyzed using factor analyses, hierarchical cluster analyses, chi-square tests, multinomial logistic regression analyses, and analyses of covariance. Three clusters were adopted: Cluster 1 (with low total numbers and severity scores of symptoms; 46.0%), Cluster 2 (with moderate total numbers and severity scores of symptoms; 44.0%), and Cluster 3 (with high total numbers and severity scores of symptoms; 10.0%). Only in Cluster 2, there were significant racial/ethnic differences in individual GI symptoms. These results provide directions for future GI symptom management among midlife women.

Abstract Background Gastrointestinal symptoms have been reported in patients with COVID-19. Several clinical investigations suggested that gastrointestinal symptoms were associated with disease severity of COVID-19. However, the relevance of gastrointestinal symptoms and mortality of COVID-19 remains largely unknown. We aim to investigate the relationship between gastrointestinal symptoms and COVID-19 mortality. Methods We searched the PubMed, Embase, Web of science and Cochrane for studies published between Dec 1, 2019 and May 1, 2021, that had data on gastrointestinal symptoms in COVID-19 patients. Additional literatures were obtained by screening the citations of included studies and recent reviews. Only studies that reported the mortality of COVID-19 patients with/without gastrointestinal symptoms were included. Raw data were pooled to calculate OR (Odds Ratio). The mortality was compared between patients with and without gastrointestinal symptoms, as well as between patients with and without individual symptoms (diarrhea, nausea/vomiting, abdominal pain). Results Fifty-three literatures with 55,245 COVID-19 patients (4955 non-survivors and 50,290 survivors) were included. The presence of GI symptoms was not associated with the mortality of COVID-19 patients (OR=0.88; 95% CI 0.71–1.09; P=0.23). As for individual symptoms, diarrhea (OR=1.01; 95% CI 0.72–1.41; P=0.96), nausea/vomiting (OR=1.16; 95% CI 0.78–1.71; P=0.46) and abdominal pain (OR=1.55; 95% CI 0.68–3.54; P=0.3) also showed non-relevance with the death of COVID-19 patients. Conclusions Gastrointestinal symptoms are not associated with higher mortality of COVID-19 patients. The prognostic value of gastrointestinal symptoms in COVID-19 requires further investigation.

Background and aimsA low fermentable oligosaccharide, disaccharide, monosaccharide, and polyols (FODMAP) diet alleviates symptoms of irritable bowel syndrome (IBS). We aimed to investigate the relationship between habitual FODMAP intake and post-prandial bowel symptoms in adults with IBS, functional diarrhoea (FD), or constipation (FD) (functional bowel disorders), and in healthy adults (controls).Methods292 participants (173 with functional bowel disorders and 119 controls) completed a food and symptom times diary. Estimated meal portion sizes were entered into the Monash FODMAP Calculator to analyse FODMAP content. Wilcoxon and ANOVA tests were used to investigate the relationship between FODMAP intake and post-prandial bowel symptoms.ResultsIBS participants experienced more post-prandial bowel symptoms compared to participants with other functional bowel disorders or controls. Meals associated with abdominal pain contained on average increased excess fructose (0.31 g vs. 0.18 g, p < 0.05), sorbitol (0.27 g vs. 0.10 g, p < 0.01), and total FODMAP (3.46 g vs. 2.96 g, p < 0.05) compared to meals not associated with pain. Abdominal swelling was associated with increased sorbitol (0.33 g vs. 0.11 g, p < 0.01), and total FODMAP (3.26 g vs. 3.02 g, p < 0.05) consumption. Abdominal bloating was associated with increased galacto oligosaccharide consumption (0.18 g vs. 0.14 g, p < 0.05).ConclusionThese findings support the role of FODMAP in post-prandial bowel symptom onset, however, the amount and type of FODMAP triggering symptoms vary between individuals. Future research should investigate the relationship between the effect of individual FODMAP consumption on post-prandial bowel symptoms for each subtype, the interaction of FODMAP with differing functional bowel disorders and whether longitudinally symptoms and dietary intake are stable.

Purpose: To evaluate the management of children with severe gastrointestinal symptoms during the disease course of COVID-19 and multisystem inflammatory syndrome (MIS-C). Methods: After ethical approval, we reviewed the medical records, retrospectively, of children with COVID-19 or MIS-C requiring surgical consultation for severe gastrointestinal symptoms. Results: The subjects comprised 15 children, 13 with MIS-C and 2 with COVID-19. Twelve children (80%) had been in known close contact with a person with SARS-CoV-19 and 13 were positive for Anti-SARS-CoV-2 IgG. All the children had experienced fever for at least 1 day and had signs of involvement of two or more systems. Three patients required surgical intervention: one underwent surgical exploration with a presumptive diagnosis of acute appendicitis in the referring center and was transported to our center following clinical deterioration, where a diagnosis of MIS-C was confirmed; and the remaining two developed appendicitis during hospitalization for COVID-19. All three patients had a longer duration of abdominal pain, a higher number of lymphocytes, and a lower level of inflammatory markers than the non-surgically managed patients. None of the patients presenting with MIS-C underwent surgical exploration. Conclusion: Gastrointestinal involvement may mimic acute abdomen in children with COVID-19. Thus, children presenting with acute abdomen in the pandemic era require careful evaluation and prompt diagnosis to avoid unnecessary surgical intervention. [ABSTRACT FROM AUTHOR]

The SARS-CoV-2 pandemic resulted in an unprecedented global crisis. SARS-CoV-2 primarily causes lung infection trough the binding of the virus with the ACE-2 cell receptor located on the surface of the alveolar epithelial cells. Notably, ACE-2 cell receptors are also expressed in the epithelial cells of the intestinal tract (GI). Recent data showed that the microbial communities of the GI might act as local and systematic inflammatory modulators. Gastrointestinal symptoms, including diarrhea, are frequently observed in infected individuals, and recent released data indicate that SARS-CoV-2 may also spread by fecal–oral transmission. Moreover, the gut microbiota's ecosystem can regulate and be regulated by invading pathogens, including viruses, facilitating an effective immune response, which in turn results in less severe diseases. In this regard, increased SARS-CoV-2 mortality and morbidities appear to be frequently observed in elderly immunocompromised patients and in people with essential health problems, such as diabetes, who, indeed, tend to have a less diverse gut microbiota (dysbiosis). Therefore, it is important to understand how the interaction between the gut microbiota and SARS-CoV-2 might shape the intensity of the infection and different clinical outcomes. Here, we provide insights into the current knowledge of dysbiosis during SARS-CoV-2 infection and methods that may be used to re-establish a more correct microbiota composition.

Background: We aimed to explore the relationship between the sleep and gastrointestinal symptoms in patients with irritable bowel syndrome (IBS) from the perspective of personality factors. Methods: Overall, 167 patients with IBS-– from First Affiliated Hospital of Nanjing Medical University in Jiangsu Province of China in 2019 were included. Gastrointestinal Symptom Score (GIS), Chinese version of Pittsburgh Sleep Quality Index (PSQI) and Eysenck Personality Questionnaire (EPQ) were used to assess gastrointestinal symptoms, sleep and personality. We use mediator variables analyze to explore the relationship between sleep, neurotic personality and gastrointestinal symptoms in IBS patients. Results: 48.5% of IBS patients had sleep disorders. IBS patients with high neuroticism had higher total PSQI scores, longer sleep latency, worse sleep persistence, more nocturnal sleep disturbances and daytime dysfunctions, and more use of sleep medication (P

Background: The Coronavirus Disease 2019 (COVID-19) pandemic poses a massive crisis to global public health. Gastrointestinal (GI) symptoms are increasingly reported in COVID-19. The characteristics of laboratory findings of COVID-19 are critical for clinical diagnosis and treatment. Objectives: The study aimed to summarize laboratory features in COVID-19 with GI symptoms and non-GI symptoms. Design: This study was a systematic review and meta-analysis. Electronic literature searches were conducted for studies that included patients infected COVID-19 with GI symptoms and non-GI symptoms. GI symptoms included diarrhea, abdominal pain, nausea and vomiting, and anorexia. This study used a random-effects model to assess pooled data. Data sources and methods: We systematically searched PubMed, Embase, Cochrane, Web of Science for studies through 31 October 2021, with no language restrictions. We used the following search terms: 'COVID-19' OR '2019-nCoV' OR 'SARS-CoV-2' OR 'coronavirus 2019' OR 'severe acute respiratory syndrome coronavirus 2' OR 'coronavirus' OR 'novel coronavirus' OR 'nCoV' AND 'gastrointestinal symptoms' OR 'digestive symptoms' AND 'clinical feature' OR 'clinical characteristics.' Data mostly originated from Chinese and American studies. Results: Of 796 identified studies, 14 were eligible and were included in our analysis (N = 8396 participants). Meta-analysis showed that GI symptoms group had an elevated alanine aminotransferase (ALT) [pooled mean difference (MD), 4.5 U/L; 95% confidence interval, [0.45, 8.55]; p = 0.03; I 2 = 87%]. No publication bias was detected by Begg's and Egger's regression test (p = 0.130). COVID-19 with the GI symptoms also showed a trend toward decreased white blood cell count, lymphopenia, neutrophilia, thrombocytopenia and elevated total bilirubin. Conclusion: GI symptoms are common in COVID-19. No significant differences were found in most laboratory indicators except elevated ALT. Registration: CRD42020209039 (PROSPERO).

Background: COVID-19 is a newly emerging disease that causes a pandemic situation in the world. Coronavirus can enter into the body in several ways and it damages other organs of the body in addition to the respiratory system. This study aimed at verifying extra-pulmonary manifestation of COVID-19. Methods: The present study was conducted as cross-sectional in a single center from March 1 to May 1 2020 at Firoozgar educational Hospital in Tehran, Iran. 107 patients with confirmed COVID-19 pneumonia according to WHO interim guidance were recruited in this study. Extra-pulmonary manifestations of COVID-19 were recorded. SPSS version 26 was used for all the analyses. Results: The mean (SD) and the median age were 59.3 (17.4) and 62.0 years, respectively and 58 (54.2%) were men. Body temperature of the patients who were equal or less than 60 years was significantly higher than other patients (39.02 vs. 38.08°C, p=0001). The most common extra-pulmonary manifestation was GI symptoms including nausea, vomiting, abdominal pain, diarrhea, hepatocellular Liver Function Test (LFT) abnormality, cholestatic LFT abnormality, and amylase lipase incensement [37 patients (34.6%]. Ophthalmological, cardiac, neurological and dermatological manifestations were shown in 6.5, 6.5, 14.9 and 14.0% of the patients, respectively. Conclusion: Investigating the clinical and radiological symptoms of COVID-19 showed that SARS-CoV-2 infection may also be associated with extrapulmonary symptoms. Therefore, clinicians and radiologists should be familiar with such symptoms of the disease. [ABSTRACT FROM AUTHOR]

Objective: COVID-19 pandemic has infected the entire world and causes obsolete morbidity and mortality. While respiratory symptoms are the most frequently reported, several recent studies revealed that gastrointestinal symptoms are not uncommon. Our aim in this observational study is to reveal the gastrointestinal symptoms of COVID-19 patients. Patients and Methods: Data of COVID-19 patients with gastrointestinal symptoms were recorded and retrospectively analyzed during their hospital follow-up period. 82 patients participated in the study and later on had a positive polymerase chain reaction (PCR) test. Gender, age, systemic and gastrointestinal complaints, medical and surgical disease history, laboratory results, thorax computer tomography (CT) findings, and characteristics of gastrointestinal system (GIS) symptoms of patients were also recorded. Data were analyzed by statistical software. Results: The most common typical symptoms of COVID-19 patients were cough, anosmia, debility, and shortness of breath. Further, most of the gastrointestinal symptoms found in COVID-19 patients were nonspecific abdominal pain. Lymphopenia and elevated liver transaminases were the most common findings of the tests. Patients with diarrhea indicated watery diarrhea. Two patients also had ileus, they healed spontaneously without surgical intervention. Furthermore, all patients were discharged without any problems. Conclusion: Gastrointestinal symptoms are typical in COVID-19 patients. However, these symptoms do not seem to have a detrimental effect on the progression of the disease. In our study group, there was no need for surgical intervention, but COVID-19 patients with gastrointestinal symptoms should be treated by a multidisciplinary approach. [ABSTRACT FROM AUTHOR]

Background: Gastrointestinal symptoms have been reported in patients with COVID-19. Several clinical investigations suggested that gastrointestinal symptoms were associated with disease severity of COVID-19. However, the relevance of gastrointestinal symptoms and mortality of COVID-19 remains largely unknown. We aim to investigate the relationship between gastrointestinal symptoms and COVID-19 mortality. Methods: We searched the PubMed, Embase, Web of science and Cochrane for studies published between Dec 1, 2019 and May 1, 2021, that had data on gastrointestinal symptoms in COVID-19 patients. Additional literatures were obtained by screening the citations of included studies and recent reviews. Only studies that reported the mortality of COVID-19 patients with/without gastrointestinal symptoms were included. Raw data were pooled to calculate OR (Odds Ratio). The mortality was compared between patients with and without gastrointestinal symptoms, as well as between patients with and without individual symptoms (diarrhea, nausea/vomiting, abdominal pain). Results: Fifty-three literatures with 55,245 COVID-19 patients (4955 non-survivors and 50,290 survivors) were included. The presence of GI symptoms was not associated with the mortality of COVID-19 patients (OR=0.88; 95% CI 0.71–1.09; P=0.23). As for individual symptoms, diarrhea (OR=1.01; 95% CI 0.72–1.41; P=0.96), nausea/vomiting (OR=1.16; 95% CI 0.78–1.71; P=0.46) and abdominal pain (OR=1.55; 95% CI 0.68–3.54; P=0.3) also showed non-relevance with the death of COVID-19 patients. Conclusions: Gastrointestinal symptoms are not associated with higher mortality of COVID-19 patients. The prognostic value of gastrointestinal symptoms in COVID-19 requires further investigation.

Superior mesenteric artery (SMA) syndrome is an uncommon phenomenon caused by the compression of the third portion of the duodenum between the aorta and the SMA. Here, we present a previously healthy 15-year-old male who presented with early satiety and 20 kg weight loss. Computed tomography (CT) demonstrated a massive retroperitoneal liposarcoma displacing the entire small intestine into the right upper quadrant. Following resection of the large mass, the patient was intolerant of oral intake despite evidence of bowel function. Abdominal CT revealed a narrowing of the duodenum at the location of the SMA. A nasojejunal feeding tube was placed past this area, and enteral nutrition was initiated before slowly resuming oral intake. Post-operative SMA syndrome is an uncommon complication but should be considered in patients intolerant of oral intake following resection of large abdominal tumors associated with extensive retroperitoneal fat loss, even in the absence of concomitant major visceral resection.

To evaluate the relationship between the severity of autism, severity of gastrointestinal symptoms and serum zonulin levels as a marker of increased intestinal permeability in children. Serum zonulin levels were determined in 56 children with ASDs and 55 healthy children. The severity of gastrointestinal symptoms and ASD symptoms was assessed with the Gastrointestinal Symptom Rating Scale (GSRS) and Childhood Autism Rating Scale (CARS), respectively. Serum zonulin levels were significantly higher than healthy controls in children with severe autism. A positive correlation was found between the CARS score, GSRS score and serum zonulin levels (r = ; P <.001). Our findings suggest that the severity of gastrointestinal symptoms and severity of autism might be related to increased intestinal permeability in ASDs children. [ABSTRACT FROM AUTHOR]

Introduction: It is important to identify the relationship between COVID-19 and gastrointestinal symptoms for health organizations in different communities. Aim: To assess the relationship between gastrointestinal symptoms and COVID-19. Material and methods: It was a cross-sectional descriptive-analytical study that was conducted on 381 patients those where admitted to Imam Hossein Hospital with a confirmed diagnosis of COVID-19 on nasopharyngeal polymerase chain reaction testing for SARS-CoV-2 from first March to end of June in Tehran city; 2020. Data was entered and analyzed by using SPSS version 22 and level of significant was consider less than 0.05. Results: Out of all the patients with COVID-19, 164 (43%) had gastrointestinal symptoms. The most symptoms of them were nausea (19.2%), vomiting (17.2%), abdominal pain (15.7%), diarrhoea (12.6%), haematomas (1%), melena (1.6%), rectal bleeding (1.6%), and constipation (1.8%), respectively. The mean D-dimer1 value was significantly different between the 2 groups with gastrointestinal symptoms and no gastrointestinal symptoms. In other words, there is a strong relationship between the variable D-dimer1, which is one of the important symptoms showing the severity of COVID-19 disease, and gastrointestinal symptoms (p < 0.0001). Conclusions: Our finding shows a statistical relationship between the level of D-dimer and gastrointestinal symptoms in patients with COVID-19. The mortality rate was higher in patients with gastrointestinal symptoms, which is an important outcome for gastroenterologists. [ABSTRACT FROM AUTHOR]

Abstract Background The outbreak of coronavirus disease 2019 (COVID-19) is now becoming an enormous threat to public health. The clinical spectrum of COVID-19 is extensive, of which critical cases are with rapid disease progression and high mortality. The aim of our study is to summarize the characteristics of different subtypes and explore risk factors of illness severity for early identification and prompt treatment. Methods In this retrospective study, we collected data of patients confirmed COVID-19 in Zhejiang Province from 17 January to 12 February 2020. According to the definition of clinical classification, we divided confirmed cases into four types, and summarize epidemiological and clinical characteristics, laboratory and radiograph findings, treatments, and outcomes, respectively. Moreover, we used univariate and multivariate ordinal logistic regression models to explore risk factors for the severity of illness in patients with COVID-19. Results A total of 788 patients were enrolled in our study, of whom 52 cases (6.6%) were mild type, 658 cases (83.5%) were common type, 61 cases (7.2%) were severe type, and 17 cases (2.2%) were critical type. Multivariate ordinal logistic regression demonstrated increasing odds of the severity of illness in patients with COVID-19 associated with male (odds ratio [OR] = 1.7, 95% confidence interval [CI]: 1.2–2.6 P = 0.008), fever (OR = 3.6, 95% CI: 2.1–6.3, P

OBJECTIVES: The current study aimed to examine the cross-sectional association between shift work and gastritis using endoscopic evaluation. METHODS: We collected questionnaire data from 964 non-shift workers and 290 shift workers aged 22–40 years at an electronics company, comprising age, smoking status, alcohol consumption, physical activity, occupational stress, and gastrointestinal symptoms. We performed a gastroendoscopy of participants. Along with describing the gastroendoscopic results, we analyzed the correlations between gastritis and shift work using multiple logistic regression analysis. RESULTS: In terms of gastrointestinal symptoms, night shift workers complained more of indigestion than non-shift workers (P

Postural orthostatic tachycardia syndrome (POTS) is characterized by exaggerated orthostatic tachycardia in the absence of orthostatic hypotension. The pathophysiology of POTS may involve hypovolemia, autonomic neuropathy, a hyperadrenergic state, and cardiovascular deconditioning, any of which can co-occur in the same patient. Furthermore, there is growing evidence of the role of autoimmunity in a subset of POTS cases. In recent years, investigators have described an increased rate of autoimmune comorbidities as evidenced by the finding of several types of neural receptor autoantibody and non-specific autoimmune marker in patients with POTS. In particular, the association of the disease with several types of anti-G protein-coupled receptor (GPCR) antibodies and POTS has frequently been noted. A previous study reported that autoantibodies to muscarinic AChRs may play an important role in POTS with persistent, gastrointestinal symptoms. To date, POTS is recognized as one of the sequelae of coronavirus disease 2019 (COVID-19) and its frequency and pathogenesis are still largely unknown. Multiple autoantibody types occur in COVID-related, autonomic disorders, suggesting the presence of autoimmune pathology in these disorders. Herein, we review the association of anti-GPCR autoantibodies with disorders of the autonomic nervous system, in particular POTS, and provide a new perspective for understanding POTS-related autoimmunity.

Endometriosis is an estrogen-dependent chronic disease characterized by the presence of endometriumlike tissue outside the uterus and is often associated with symptoms, such as dysmenorrhea, dysuria, dyschezia, chronic pelvic pain, and infertility. Moreover, women diagnosed with endometriosis can report gastrointestinal symptoms, including bloating, constipation or diarrhea, and abdominal cramping, which can be associated with irritable bowel syndrome and can result in the misdiagnosis of endometriosis as irritable bowel syndrome at first. Treatment usually involves hormonal therapy, pain management, surgery, and/or assisted reproductive techniques in case of infertility. Nonetheless, these treatment methods can be insufficient for alleviating symptoms or can have unacceptable side effects, leading to noncompliance. Therefore, women often apply self-management strategies, including dietary interventions. One of the diets frequently suggested as a tool to manage endometriosis-related symptoms on social media and patient forums is a gluten-free diet. Although a gluten-free diet has been proven effective in managing nonceliac wheat sensitivity or celiac disease, its effectiveness in endometriosis remains uncertain. The Nurses' Health Study II found it unlikely that gluten intake was a strong factor in endometriosis etiology and symptomatology. To the best of our knowledge, the most frequently cited and sole published intervention study on the efficacy of a gluten-free diet for endometriosis has several important limiting factors, including the absence of a control group. In addition, gluten consumption is highly susceptible to a placebo effect and a nocebo effect, where women might experience symptom relief after eliminating gluten and return of symptoms after they consume gluten again, solely because they believe that gluten is bad for them. Despite the inverse association between body mass index and endometriosis and between a gluten-free diet and increased body mass index, this is an association, and no causality was proven. In addition, other factors should be taken into consideration. Of note, a gluten-free diet is expensive, has limited availability, and has a significant effect on quality of life. Moreover, without proper dietary guidance, it may adversely affect the gastrointestinal microbiome. Therefore, scientifically substantiated advice regarding the use of a gluten-free diet for endometriosis-related symptoms is currently not available, and a gluten-free diet should be discouraged unless there is an additional diagnosis of nonceliac wheat sensitivity or celiac disease., (© 2024 The Authors.)

Introduction: SARS-CoV-2 virus manifests itself with primary lung damage but also has intestinal involvement. In this study, we aimed to investigate the frequency of gastrointestinal symptoms (GIS) and the relationship of GIS with readmission to the hospital within 30 days in SARS-CoV-2 infected patients who were hospitalized in a specified pandemic hospital. Materials and Methods: Symptomatic patients diagnosed with rapid antibody positivity with real-time polymerase chain reaction and typical thorax computed tomography findings were included in this retrospective cohort observational study. Demographic and clinical data were obtained from electronic medical records. Hospital-associated GIS were considered as experiencing at least one of the GIS such as gas, bloating, diarrhea, and constipation developing within72 h after hospital admission. Results: The mean age of the patients was 58 ± 14.4 years and 60.7% were men. 82% of hospitalizations were a moderate and severe disease. 71.4% of patients without GIS had at least one of the GIS after hospitalization. As the severity of the disease increased, the frequency of the severity of gastrointestinal symptom increased. GIS bowel disorders were more prominent in patients with moderate and severe disease. Antibiotic and specific treatment (anti-Il-1, anti-Il-6) contributed to the occurrence of gastrointestinal symptom in SARS-CoV-2 inpatients. Conclusion: According to our observations of the second wave of the pandemic, the presence, frequency, and severity of gastrointestinal symptom in inpatient is associated with severity of lung disease and increased readmission rate after discharge.

Objectives: Psoriasis is a common chronic recurrent dermatitis. Accumulating observations show gut microbiota dysbiosis in psoriasis. We intend to further investigate the relationship between intestinal microbiota and psoriasis development.Design: We first performed an epidemiological investigation on differences of gastrointestinal discomfort symptoms between patients with psoriasis and general population. Then variation of gut microbiota in patients with psoriasis (un)treated with acitretin plus narrow-band ultraviolet B (NB-UVB) was analyzed by 16S rRNA sequencing. We last compared recovery status and vital cytokines (lesion and intestine) of mouse psoriasiform models, which were transplanted with fecal microbiota from patients with psoriasis or healthy controls.Results: (1) About 85.5% of patients with psoriasis vs. 58.1% of healthy controls presented with at least one gastrointestinal symptom. The prevalence of investigated symptoms (e.g., abdominal distension and constipation) were significantly higher in patients, compared with controls (p < 0.05). Passing flatus and constipation were significantly correlated with psoriasis (p < 0.05 in both cases). (2) The abundance of Ruminococcaceae family, Coprococcus_1 genus, and Blautia genus were decreased with psoriasis improvement (p < 0.05, respectively), which had been demonstrated significantly increased in psoriasis. (3) Mice receiving psoriatic microbes transplantation showed delayed recovery of psoriasiform dermatitis and less reduction of interleukin (IL)-17A than those receiving healthy microbiota or blank control (p < 0.05 and p < 0.01, respectively).Conclusion: Multiple evidence we provided here preliminarily demonstrates the involvement of gut microbiota in the different degree of psoriasis activity. The strategy based on overall microbial communities is expected to be a promising supplementary for long-term management of psoriasis.

The SARS-CoV-2 pandemic resulted in an unprecedented global crisis. SARS-CoV-2 primarily causes lung infection trough the binding of the virus with the ACE-2 cell receptor located on the surface of the alveolar epithelial cells. Notably, ACE-2 cell receptors are also expressed in the epithelial cells of the intestinal tract (GI). Recent data showed that the microbial communities of the GI might act as local and systematic inflammatory modulators. Gastrointestinal symptoms, including diarrhea, are frequently observed in infected individuals, and recent released data indicate that SARS-CoV-2 may also spread by fecal–oral transmission. Moreover, the gut microbiota’s ecosystem can regulate and be regulated by invading pathogens, including viruses, facilitating an effective immune response, which in turn results in less severe diseases. In this regard, increased SARS-CoV-2 mortality and morbidities appear to be frequently observed in elderly immunocompromised patients and in people with essential health problems, such as diabetes, who, indeed, tend to have a less diverse gut microbiota (dysbiosis). Therefore, it is important to understand how the interaction between the gut microbiota and SARS-CoV-2 might shape the intensity of the infection and different clinical outcomes. Here, we provide insights into the current knowledge of dysbiosis during SARS-CoV-2 infection and methods that may be used to re-establish a more correct microbiota composition.

Objective: The aim of this descriptive and cross-sectional study was to examine the relationship between type D personality and gastrointestinal symptoms in patients with irritable bowel syndrome (IBS). Methods: A total of 168 of 192 patients who presented at the gastroenterology polyclinic of a university hospital between February 15 and May 15, 2019 and were diagnosed with IBS were enrolled. The data were collected using a patient identification form, the Gastrointestinal Symptom Rating Scale (GSRS), and the Type D Scale-14 (DS-14) personality assessment. Results: Of the IBS patients studied, 70.8% had type D personality. The GSRS total score of the patients with type D personality (p=0.001), as well as their reflux (p=0.001), diarrhea (p=0.01), abdominal pain (p=0.001), constipation (p=0.001), and indigestion (p=0.004) subdimension scores were statistically significantly higher than those without type D personality. Multiple regression analysis indicated that the GSRS total score and all subdimension scores except reflux had a predictive value of 20% (R2=0.203; p<0.0001). Conclusion: In all, 70.8% of individuals diagnosed with IBS were classified as type D personality. The gastrointestinal symptoms of abdominal pain, reflux, diarrhea, indigestion, and constipation were more prevalent among individuals with type D personality compared with other personality types.

Due to high prevalence of diabetes in our region (16.3%) and no data on the frequency of gastrointestinal (GI) symptoms in this population, we performed a cross-sectional study to evaluate the frequency of GIsymptoms in diabetic patients and its association between microvascular complications (retinopathy and nephropathy) and gastrointestinal symptoms in diabetic subjects.This analytical cross-sectional study was conducted from 2014 to 2016 on 233 patients with type 2 diabetes mellitus (T2DM), 30-65-year, referred to Yazd diabetic research center. They were selected by convenient sample method. A questionnaire according to Rome III Criteria was used to collect digestive information related to diabetes. Last HbA1c (Since 2-3 months ago) was available in the patient's medical folder. Diabetic nephropathy defines to increased excretion rate of albumin in the urine in the range of above 30 mg/g creatinine. Diabetic retinopathy was examined by an expert ophthalmologist (retinal specialist). For the current study, 233 patients (age 30-65 years with mean age of 57.43±10.49 years, 102 (43.8%) males and 131 (56.2%) females) were included. Among 233 patients, 91 cases (39.1%) had nephropathy,and 111(47.6%) subjects had different degrees of retinopathy. Bloating and early satiety and upper GI symptoms were higher in the subjects with retinopathy than another group. In summary, this study provides evidence that GI symptoms in diabetic subjects are independently linked to diabetic complications, particularly to retinopathy.

Objective: To explore the impact of common gastrointestinal (GI) symptoms on psychological symptoms, sleep quality, and quality of life in patients with inflammatory bowel disease (IBD)., Methods: A unified questionnaire was developed to collect clinical data on the mental psychology and quality of life of IBD patients from 42 hospitals in 22 provinces in P. R. China from September 2021 to May 2022. The general clinical characteristics, psychological symptoms, sleep quality, and quality of life of IBD patients with different numbers of GI symptoms were analyzed by descriptive statistical analysis., Results: A total of 2,478 IBD patients were finally analysed in this study, including 365 without GI symptoms (14.7%), 752 with single symptoms (30.4%), 841 with double symptoms (33.9%), and 520 with three symptoms (21.0%). Compared with patients without GI symptoms, patients with only simple abdominalgia or diarrhea or hematochezia showed significantly higher levels of anxiety and depression and worse quality of life (all P  <   0.05). Compared with asymptomatic patients, patients with double symptoms (e.g. abdominalgia plus hematochezia, diarrhea plus hematochezia, abdominalgia plus diarrhea) and patients with three symptoms (abdominalgia, diarrhea, and hematochezia) showed significantly higher levels of anxiety and depression and worse sleep quality and quality of life (all P  <   0.05)., Conclusion: Compared with IBD patients without gastrointestinal symptoms, patients with gastrointestinal symptoms were more likely to experience anxiety, depression, sleep disturbances, and poorer quality of life., Competing Interests: The authors declare no conflict of interest., (© The Author(s) 2024.

The low fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) diet, designed to alleviate symptoms in individuals with irritable bowel syndrome (IBS), focuses on limiting the consumption of poorly absorbed fermentable carbohydrates known as FODMAP. These FODMAP are believed to be the primary triggers for food-related gastrointestinal symptoms in functional gastrointestinal disorders. However, there is currently insufficient direct evidence investigating the role of low FODMAP diets in cancer patients undergoing treatment. This review aims to summarize the current evidence on the low FODMAP diet and its potential implications for cancer patients in terms of treatment outcomes, alleviating gastrointestinal symptoms, and overall health. A systematic literature search was conducted using databases, including PubMed, Scopus, Google Scholar, Web of Science, and Cochrane. Five studies met the criteria for inclusion in the review, and these studies covered rectal toxicity during radiotherapy, gastrointestinal symptoms in colorectal cancer patients, acute gastrointestinal toxicity during pelvic external beam radiotherapy, symptoms in patients with radiation-induced enteropathy, and chronic gastrointestinal sequelae resulting from pelvic organ cancer treatment. The available evidence suggests that a low FODMAP diet may offer advantages in reducing rectal gas and volume during radiotherapy, alleviating diarrhea symptoms, reducing symptom deterioration, and improving quality of life. However, these studies highlight the need for large-scale randomized trials, long-term follow-up, and guidelines to establish the efficacy, safety, and implementation strategies of the low FODMAP diet in different cancer contexts and patient populations. While preliminary findings reported some possible benefits of a low FODMAP diet for certain cancer patients, rigorous studies with large sample sizes are needed to provide more robust evidence. Further research is warranted to optimize the utilization of this diet as an adjunctive intervention for managing gastrointestinal symptoms in this population., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Almasaudi et al.)

Abstract INTRODUCTION: The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has greatly challenged public health worldwide. A growing number of studies have reported gastrointestinal (GI) symptoms. We performed a systematic review of GI symptoms associated with coronavirus disease 2019 (COVID-19) as well as of the serum levels of biomarkers related to liver function and lesion in SARS-CoV-2-infected individuals. METHODS: We surveyed relevant articles published in English, Spanish, and Portuguese up to July, 2020 in the PubMed, MEDLINE, SciELO, LILACS, and BVS databases. Moreover, we surveyed potentially important articles in journals such as the NEJM, JAMA, BMJ, Gut, and AJG. RESULTS: This systematic review included 43 studies, including 18,246 patients. Diarrhea was the most common GI symptom, affecting 11.5% of the patients, followed by nausea and vomiting (6.3%) and abdominal pain (2.3%). With regard to clinical severity, 17.5% of the patients were classified as severely ill, whereas 9.8% of them were considered to have a non-severe disease. Some studies showed increased aspartate transaminase and alanine aminotransferase levels in a portion of the 209 analyzed patients and two studies. CONCLUSIONS: Our results suggest that digestive symptoms are common in COVID-19 patients. In addition, alterations in cytolysis biomarkers could also be observed in a lesser proportion, calling attention to the possibility of hepatic involvement in SARS-CoV-2-infected individuals.

Objectives: Patients with novel coronavirus disease 2019 (COVID-19) can present with gastrointestinal symptoms as their initial symptoms or as the main manifestations during disease progression, but the clinical characteristics of these patients are still unknown.Methods: We identified COVID-19 patients who admitted to Xiangyang No. 1 People's Hospital and presented with gastrointestinal symptoms as their initial or main symptoms. Their medical records were reviewed by two independent clinical scientists. The epidemiological and clinical characteristics as well as the clinical outcomes were analyzed.Results: Among 142 confirmed COVID-19 cases, 7 (4.9%) of them presented with gastrointestinal symptoms. Three patients had gastrointestinal symptoms as the initial symptoms and chief complaints, and 4 patients as the main symptoms during disease progression. Six patients had symptoms of diarrhea (3–16 days), 7 with anorexia (7–22 days), 6 with upper abdominal discomfort (1–7 days), and 4 with nausea (1–7 days), 1 with heartburn lasting 2 days, and 2 with vomiting symptoms (1 day). The chest CT scan showed typical COVID-19 imaging features, and associated with the progression of the disease. During treatment, 2 patients died due to organ failure.Discussion: COVID-19 patients with gastrointestinal symptoms are relatively rare and might be misdiagnosed. The clinical features include watery stools, anorexia, and upper abdominal discomfort. These patients may have severe disease and be associated with a poor prognosis. The underlying mechanisms of SARS-CoV-2 related gastrointestinal symptoms need to clarify in future studies.

BackgroundEating disorders (ED) such as anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED) are often accompanied by a variety of psychological and physical comorbidities. Gastrointestinal (GI) symptoms are a classical feature in most patients with ED. The heterogeneity of studies on this topic is high, making it difficult to have a clear overview. The aim of this systematic review is therefore to provide an overview of subjectively and objectively measured differences and changes in the GI tract in patients with EDs, along with the occurrence of GI complications.MethodsA systematic literature search was conducted in PubMed, Web of Science, and Google Scholar to find all relevant studies examining GI problems in AN, BN, and BED. Quantitative analyses were performed for objective GI physiology measures where applicable.ResultsThe review differentiated between ED types and also between studies that report GI outcomes of ED in (i) human studies with an ED diagnosis excluding case reports that provide an overview of GI problems in ED and (ii) case reports with an ED diagnosis describing rare GI complications in ED. GI symptoms and impaired gastric transit times were frequent features of EDs with specific differences found for the ED types. During the time course of treatment, GI symptoms changed and/or improved but not completely. GI complications extended the range of GI problems observed, including a variety of serious complications such as gastric dilatation.ConclusionsProblems of the GI tract are frequent in patients with ED and it is likely that they complicate therapy, especially in patients with AN.Systematic Review RegistrationPROSPERO registration number: CRD42019100585.

Autism spectrum disorder [ASD] is characterized by deficits in communication and social interactions combined with repetitive and restricted patterns of behaviors. Bidirectional changes in brain-gut microbiota are known to be responsible for the pathophysiology of many brain-related disorders, such as autism, as well as well-known gastrointestinal diseases, including gut disorders. Imbalance in the composition of gut microbiota is frequently observed in individuals with ASD. It is therefore believed that this imbalance is significant in the frequent occurrence of gastrointestinal symptoms. The integrity of the intestinal barrier and the blood-brain barrier [BBB] in individuals with ASD is affected. Incompletely digested peptides, toxins, and proinflammatory cytokines cross the BBB by entering the bloodstream and reach the central nervous system. As a result of the accumulation of these elements, brain function is adversely affected. It is hypothesized that incompletely digested peptides acting as opioid agonists reduce pain sensitivity and increase the severity of autism-specific behaviors. However, it is not known exactly how opioid peptides trigger ASD symptoms after they reach the brain. Diet therapies, especially elimination diets, are considered to be an alternative treatment to prevent this condition. Gluten-free casein-free [GFCF] diet is an elimination diet that involves the removal of certain proteins from the normal diet, such as gluten and casein. However, studies that demonstrate the beneficial effects of the GFCF diet on ASD patients and explain its mechanism is limited, which supports the opioid theory. This review aims to investigate the gastrointestinal and behavioral problems that are frequently observed in ASD, the possible action mechanisms of GFCF diets, and the efficacy of these elimination diets.

Results: A total of 788 patients were enrolled in our study, of whom 52 cases (6.6%) were mild type, 658 cases (83.5%) were common type, 61 cases (7.2%) were severe type, and 17 cases (2.2%) were critical type. Multivariate ordinal logistic regression demonstrated increasing odds of the severity of illness in patients with COVID-19 associated with male (odds ratio [OR] = 1.7, 95% confidence interval [CI]: 1.2–2.6 P = 0.008), fever (OR = 3.6, 95% CI: 2.1–6.3, P < 0.001), cough (OR = 1.7, 95% CI: 1.0–2.9, P = 0.041), hemoptysis (OR = 3.4, 95% CI: 1.1–10.3, P = 0.032), gastrointestinal symptoms (OR = 1.9, 95% CI: 1.0–3.5, P = 0.047), hypertension (OR = 2.6, 95% CI: 1.2–5.6, P = 0.013). With the increase of age-grading, risk for the severity of illness was gradually higher (≤ 18 years [OR = 1.0], 19–40 years [OR = 12.7, 95% CI: 4.5–36.0, P < 0.001], 41–65 years [OR = 14.8, 95% CI: 5.2–42.1, P < 0.001], ≥ 66 years [OR = 56.5, 95% CI: 17.1–186.5, P < 0.001]). Conclusions: Clinicians should pay close attention to these features in patients with COVID-19 including older age, male, fever, cough, hemoptysis, gastrointestinal symptoms and hypertension to identify the severity of illness as early as possible.

Background: Eating disorders (ED) such as anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED) are often accompanied by a variety of psychological and physical comorbidities. Gastrointestinal (GI) symptoms are a classical feature in most patients with ED. The heterogeneity of studies on this topic is high, making it difficult to have a clear overview. The aim of this systematic review is therefore to provide an overview of subjectively and objectively measured differences and changes in the GI tract in patients with EDs, along with the occurrence of GI complications. Methods: A systematic literature search was conducted in PubMed, Web of Science, and Google Scholar to find all relevant studies examining GI problems in AN, BN, and BED. Quantitative analyses were performed for objective GI physiology measures where applicable. Results: The review differentiated between ED types and also between studies that report GI outcomes of ED in (i) human studies with an ED diagnosis excluding case reports that provide an overview of GI problems in ED and (ii) case reports with an ED diagnosis describing rare GI complications in ED. GI symptoms and impaired gastric transit times were frequent features of EDs with specific differences found for the ED types. During the time course of treatment, GI symptoms changed and/or improved but not completely. GI complications extended the range of GI problems observed, including a variety of serious complications such as gastric dilatation. Conclusions: Problems of the GI tract are frequent in patients with ED and it is likely that they complicate therapy, especially in patients with AN. Systematic Review Registration: PROSPERO registration number: CRD42019100585. [ABSTRACT FROM AUTHOR]

Prostate cancer is a major health issue, and prevention of prostate cancer and/or its progression will yield benefits for men. Difluoromethylornithine (DFMO) is an antiproliferative agent, inhibiting ornithine decarboxylase, the first enzyme in the polyamine pathway, and has been studied as a therapeutic and chemopreventive agent. The prostate has high levels of tissue polyamines and has shown sensitivity to DFMO both in vitro and in vivo.Eighty-one men participated in a 1-year randomized trial of placebo or DFMO. Prostate volume determination and biopsy of the prostate for histology and polyamine content were done at baseline and after 12 months. Other biomarker variables were assessed, including total and free prostate-specific antigen and prostate-specific antigen doubling time.Compared with baseline, men receiving DFMO had a smaller increase in prostate volume (0.14 cm(3)) than those on placebo (2.95 cm(3); P = 0.0301) at 1 year. In addition, DFMO caused a 60.8% reduction of prostate putrescine levels compared with a 139.5% increase in the placebo arm (P = 0.0014). Stratification by ornithine decarboxylase genotype showed that DFMO reduced prostate volume (P = 0.029) and putrescine levels (P = 0.0053) in the AA + GA group but not in the GG group. There were no grade 3 or 4 toxicities. There was no clinical ototoxicity, with one subclinical grade 2 hearing decline on audiogram.In this randomized placebo-controlled trial, DFMO induced a decrease of prostate putrescine levels and rate of prostate growth. The potential of this compound for prostate cancer or hyperplasia should be further studied.
