Introduction. There are an inverse association between Helicobacter Pylori (H. pylori) infection and prevalence of IBD [5, 10,11,12]. Also studies have reported an inverse association between H. pylori prevalence and disease severity of IBD [13]. H. pylori is one of the environmental infections causing changes in gut microbiota and immune system dysregulation, which may affect IBD activity. The current study aimed to compare the clinical, laboratory, and histological severity of the newly diagnosed IBD with the presence or absence of H. pylori infection. Methods. This was a retrospective study that included 50 newly diagnosed inflammatory bowel disease patients (30 ulcerative colitis patients and 20 Crohn's disease patients). Diagnosis of IBD was based on both endoscopy/colonoscopy and biopsy. Also, for assesing Disease activity was quatified by CDAI for Crohn disease and UCDAI dor ulcerative colitis. Also, fecal calprotectine was evaluated. The presence of H. pylori was evaluated by the H. pylori stool antigen test (HpSA). Results: The overall positivity of H. pylori infection in patients with IBD was 19.2%. Patients with HpSA had a significantly lower fecal calprotectine (145.57 ± 28.12 vs. 320.57 ± 67.54 (μg/mg); P= 0.02), Mayo score (4.12 ± 1.09 vs. 8.01 ± 1.23; P < 0.001) and CDAI score (112 ± 67 vs. 198 ± 89; P < 0.001) compared to those with negative HpSA. Conclusion. We reported a significantly lower H. pylori infection rate in IBD patients. H. pylori-positive IBD patients have a milder disease with less activity compared to H. pylori-negative IBD patients. [ABSTRACT FROM AUTHOR]

Background & Aims: Real-world assessments of efficacy and safety of advanced therapies used for inflammatory bowel disease (IBD) patients are limited. We aimed to report safety, efficacy and treatment persistence of new molecules (infliximab, adalimumab, vedolizumab, tofacitinib, ustekinumab) in a retrospective multicentric national Romanian analysis. Methods: We conducted a nationwide, retrospective observational multicentric study. Data were collected retrospectively from electronic and paper files. Patients who started on one of the five investigated molecules during December 2019-December 2021 were included. The main outcome measures were clinical remission, endoscopic healing, persistence on treatment and safety data. Results: A total of 678 adult patients from 24 Romanian IBD centers with a diagnosis of ulcerative colitis or Crohn's disease were included. Participants had previously failure to one (268, 39.5%), two (108, 15%) or more treatment lines and only 38% (259) were biologic naïve. In the 24 months study period, most patients were started on vedolizumab (192, 28%), followed by adalimumab, infliximab, ustekinumab and tofacitinib. In biologic-naïve patients, most physicians (72%) preferred anti-TNF treatment as first line biologic (93 patients started on infliximab, 92 on adalimumab), followed by vedolizumab, ustekinumab and tofacitinib. During follow-up, 71% (470, p=0.05) of patients achieved clinical remission and 36% (134, p=0.03) achieved mucosal healing. The 6 months milestone for persistence was reached in 78% (530) of cases. Almost half of patients (47%, 316 patients) persisted on their current treatment for over 12 months. Overall, an adverse reaction was reported for 67 (10.4%) patients, with no lethal events. Conclusions: Population of biologic-experienced IBD patients in Romania is increasing and is becoming more difficult to achieve long-term disease control. Discontinuation rates for advanced therapies are high. [ABSTRACT FROM AUTHOR]

Background & Aims: Both inflammatory bowel diseases (IBD) and ankylosing spondylitis (AS) can be considered chronic immune disorders sharing common etiopathogenetic mechanisms. Changes in the composition of the intestinal microbiota, which can lead to an abnormal mucosal response, could be the missing link between these two diseases. Our study evaluate the composition of intestinal microbiota and to characterize gut dysbiosis in patients with IBD and AS. Methods: We conducted a prospective case-control study that enrolled 124 patients [20 Crohn's disease (CD), 27 ulcerative colitis (UC), 28 AS, 17 IBD + AS and 32 controls). Intestinal microbiota analysis was performed by real-time polymerase chain reaction in stool samples. Results: The total quantity of bacteria was decreased in all investigated groups compared to the control group. In studied groups, we noticed an increased percentage of Bacteroides and Escherichia coli (E.coli) and a decreased percentage of Clostridium coccoides, Clostridium leptum, and Faecalibacterium prausnitzii compared to the control group. The percentages of Bifidobacterium (p=0.010) as well as Lactobacillus group (p=0.023) were higher in the L3 form of CD patients. In the E2 form of UC, the quantity of Bacteroides was much higher compared to the E3 form (p=0.004). In AS patients, significant correlations were observed only for the Bifidobacterium species, significantly increased in the axial form compared to peripheral disease (p=0.035). Statistically significant correlations were demonstrated between the Crohn Disease Activity Index score and the total bacterial group (p=0.023, r=-0.507), respectively Bacteroides (p=0.021, r=-0.511) and between the Mayo score and Lactobacillus (p=0.001), respectively E. coli (p=0.001). In IBD + AS group, the Crohn Disease Activity Index score was inversely correlated with the total bacterial group (p=0.010) and directly correlated with Lactobacillus (p=0.047). Conclusions: Intestinal dysbiosis is associated with both IBD and AS. In the association of IBD with AS, dysbiosis is intermediate, but it is associated with the more severe articular disease. Bifidobacterium and Lactobacillus (commonly used as probiotics!) were found to be increased in the association between active IBD and active AS. Further studies are needed to understand how dysbiosis regulates the gut immune system and contributes to intestinal and articular inflammation. [ABSTRACT FROM AUTHOR]
