1. Introduction. Multiple cytokines have been studied for their role in the propagation of the inflammatory process related to inflammatory bowel diseases (IBD), but the role of interleukin-4 remains controversial. The aim of this study was to evaluate the role of two IL-4 gene single nucleotide polymorphisms (SNPs) in disease susceptibility and phenotypic expression. 2. Materials and Methods. A group of 160 patients with IBD (86CD/74UC) and 160 healthy controls were genotyped for IL-4 rs2243250/−590C/T and rs2070874/−34C/T using real-time polymerase chain reaction with TaqMan assay. 3. Results. The analysis of IBD patients and controls revealed a significantly reduced frequency of the minor allele T of both SNPs in CD patients (p = 0.03, OR 0.55 and p = 0.02, OR 0.52) and for the entire IBD group (p = 0.01, OR 0.57 and p = 0.01, OR 0.55). Haplotype analysis identified the most frequent haplotype (rs2243250/rs2070874 CC) associated with a high risk for developing IBD (either UC or CD) (p = 0.003). IBD patients with extraintestinal manifestations had significantly increased frequency of the minor alleles T. We also found an association between the presence of allele C of rs2070874 and response to antiTNF treatment. 4. Conclusions. This is the first study to investigate the IL-4 gene's relation to IBD susceptibility conducted in Romania. Both SNPs were found to be associated with disease susceptibility and phenotypic features, such as extraintestinal manifestations and response to antiTNF agents. [ABSTRACT FROM AUTHOR]

Background & Aims: Therapeutic targets in ulcerative colitis (UC) have evolved over time from clinical remission to biological and endoscopic remission. Histologic remission remains a debatable outcome due to lack of data regarding its impact on long-term evolution. The development of histologic activity scores has brought standardization. We aimed to identify mucosal markers differentiating histological inflammation from histological remission in UC patients. Methods: The gene expression levels of 84 genes associated with inflammatory bowel diseases have been analyzed in 43 colonic mucosa samples from 30 patients with UC. The gene expression levels have been correlated with histological inflammation score of Geboes. Patients with endoscopic remission were divided by histological activity into two groups and molecular results were compared in order to identify differences in the mucosal gene expression. Results: We found a significant Pearson correlation (p<0.001 and r>0.5) between the Geboes score and the expression of 29 genes, whereas negative correlation (p<0.001 and r<-0.50) was observed with two genes in the entire UC cohort. In the subgroup of patients with endoscopic remission three transcripts: formyl-peptide receptor 1 (FPR1), matrix metalloproteinases 1 (MMP1) and mucine 1 (MUC1) were significantly up-regulated in patients with histological inflammation compared to patients with histologic remission. Conclusion: Our study further emphasizes the importance of histological assessment when endoscopic mucosal healing is present, as FPR1, MMP-1 and MUC1 were all significantly upregulated in patients with histological alterations.

Background & Aims: Even though Romania has one of the highest incidence and mortality in colorectal cancer (CRC) in Europe, there is currently no organized screening program. We aimed to assess the results of our opportunistic CRC screening using colonoscopy. Methods: A single center retrospective study to include all opportunistic screening colonoscopies performed in two 18 month periods (2007-2008 and 2012-2013) was designed. All asymptomatic individuals without a personal or family history of adenoma or CRC and with complete colonoscopy performed in these two time periods were included. Results: We included 1,807 individuals, 882 in the first period, 925 in the second period. There were 389 individuals aged below 50, 1,351 between 50 and 75 and 67 older than 75 years. There were 956 women (52.9%), with a mean age of 58.5 (median 59, range 23-97). The detection rates were 12.6% for adenomas (6.1% for advanced adenoma) and 3.4% for adenocarcinoma. Adenoma incidence (4.9% in subjects under 50, 14.7% in those aged 50 to 75, and 16.4% in those older than 75, p<0.0001) and size (6.3mm in subjects younger than 50, 9.2mm in those 50 to 75 and 10.8mm in those older than 75, p=0.015) significantly increased with age. Adenoma incidence increased in the second period (14.8% vs. 10.3%, p=0.005), while adenoma size decreased in the second period (8.4mm vs. 10mm, p=0.006). There were no procedure related complications. Conclusions: The neoplasia detection rate was 16% (12.6% adenoma, 3.4% adenocarcinoma). Adenoma incidence and size increased with age in both cohorts. In the second screening period significantly more and smaller adenomas were detected. [ABSTRACT FROM AUTHOR]

Despite recent discoveries, patients with inflammatory bowel disease (IBD) still face challenges with attainment of remission. The objectives of the study were to identify the characteristics of patients with the Freiburg Personality Inventory and the intensity of the intestinal disease, comorbidities that could be related to the personality of the subjects. Data were collected in the period 2019--2020 from 46 patients and used nonparametric methods. Compared to the normative sample, the Inhibitedness, Health Concerns, and Emotionality scales had significantly higher raw scores. The Social Orientation, Frankness, and Extraversion scales had significantly lower raw scores. Health status was a medical factor that influenced the Somatic Complaints scale, patients who had lesions or comorbidities had significantly higher raw scores. Patients who had comorbidities in addition to IBD had considerably higher raw scores on the Excitability scale. Psychotherapeutic change interventions regarding life perception are required to tackle the description of subjective suffering related to physical inconveniences (Somatic Complaints scale), a strong orientation toward performance (Strain scale), mood swings, anxiety, and pessimism (Emotionality scale). Another intervention is reconsidering values and (re) prioritization, such as family, intimate relationships, friends, health, growth, development, balanced work, all of which can promote a feeling of well-being and balance.

Aims. Variceal bleeding is a common and severe cause of hospitalization in cirrhotic patients. We analyzed how the COVID-19 waves modified the outcome of the patients compared to COVID-19 extra-wave intervals. Methods. We retrospectively included all patients hospitalized between March 2020 and December 2021 for variceal bleeding. They were separated in 2 categories: hospitalizations during COVID-19 extrawaves period and the COVID-19 waves. Variables like sex, age, hemoglobin at presentation, endoscopic timing, hemostatic methods, transfusion necessity, duration of hospitalization and mortality were analyzed. Results. Out of 76 patients (2020-2021), 20patients were hospitalized during the COVID-19 waves. The median age did not differ significantly across groups (61 years [IQR: 52-65] vs 58years [IQR: 44-64]), 59 patients being male and 17 being female. The number of admissions for variceal bleeding and gastroscopy requirement and timing were similar regardless of the studied period (p > 0.05). Median hemoglobin admission values were significantly lower in the following subgroups: patients in whom gastroscopy was performed in less than 6 hours or more than 12 hours (p = 0.045) and patients requiring PRBC transfusion (p = 0.018). There were also no differences in duration of hospitalization and mortality between the two studied periods (p>0.05). Conclusions. The number of patients remained relatively constant in both periods. We found no differences in the management and outcomes of patients with variceal bleeding throughout the COVID pandemic. Our results might be influenced by the low number of patients and need confirmation on larger cohorts. [ABSTRACT FROM AUTHOR]

Intestinal strictures are an important complication of Crohn's disease (CD), with ~40% of patients developing symptomatic obstruction within 10 years of diagnosis. However, there is a paucity of research examining the mechanisms driving the development of fibrotic strictures in CD. The present study aimed to identify the mucosal markers associated with stricturing complications by examining the differences in the gene expression profiles of two patient cohorts: Patients diagnosed with inflammatory CD (n=12) and patients with stricturing CD (n=9). For each patient, a paired sample of inflamed and uninflamed mucosa was isolated and assessed by quantitative PCR using a large panel of genes associated with inflammatory bowel disease. The presents study revealed a significantly increased level of four genes in the mucosa of patients with strictures compared with the inflammatory pattern of the disease: Formyl-peptide receptor 1 [P=0.019; fold change (FC)=11.6], C-C chemokine receptor type 1 (P=0.035; FC=5.44), IFN-γ-inducible protein 10 (P=0.037; FC=3.8) and C-C chemokine ligand 25 (P=0.048; FC=3.56). The augmented expression of these four genes in the CD stricturing phenotype, if confirmed in larger cohorts of patients, could help elucidate the mechanisms leading to disease-associated complications.
