Background: Inflammatory bowel disease (IBD) frequently manifests at a young age, during the peak fertility years. Understanding the risks of negative pregnancy outcomes associated with IBD is crucial for effective pregnancy management and support. Additionally, it is essential to provide patients with the necessary knowledge to make informed choices and foster their confidence in navigating pregnancy while maintaining effective disease management. Although IBD frequently appears during the peak fertility years, knowledge about managing pregnancy in the context of IBD remains limited and often inaccurate among both physicians and patients. Our study aims to assess the complications occurring during pregnancy in patients with IBD, considering the level of disease activity, and to evaluate the standard of care provided to patients with chronic inflammatory conditions through a cohort analysis. Methods: Patients with IBD who had children were included in this single-center mixed-method (retrospective and prospective) study. Clinical data, disease progression, course of pregnancy, and complications were examined in women. Outcomes for children of men with IBD were also analyzed. To supplement the data, a survey addressing various pregnancy-related topics, including all patients from the university outpatient clinic for IBD, was conducted over a period of six months. Results: A total of 410 patients were screened retrospectively between 2010 and 2021. In total, 134 patients who had children were included in the study: 51.4% (n = 69) had Crohn's disease, 44% (n = 59) had ulcerative colitis, and 4.6% (n = 6) had unclassified inflammatory bowel disease. Of the women, 85% (n = 34) were in remission for at least three months before pregnancy, 14.6% (n = 6) experienced an acute flare-up during pregnancy, and 10.3% (n = 4) and 7.7% (n = 3) had active disease at the time of delivery and during breastfeeding, respectively. Patients with IBD who were in remission before pregnancy did not experience a higher risk of pregnancy complications (no cases of pre-eclampsia or placental abruption were reported in this group). However, the rates of gestational diabetes and fever during pregnancy were 10% for those in remission, compared to 25% for those with active disease. Conclusions: Patients with IBD in remission did not present an increased risk of pregnancy complications. However, our survey indicates that those with active disease at conception were more likely to experience complications such as gestational diabetes and fever. These findings underscore the importance of adequate patient education regarding the safety of various IBD medications during pregnancy in order to avoid pregnancy-related complications.

Background: Vedolizumab (VDZ) is a well-established and important therapeutic option in the treatment of patients with inflammatory bowel disease (IBD). However, the significance of therapeutic drug monitoring (TDM) with VDZ remains a contradictory field in daily clinical practice. Our study aims to clarify the predictive impact of VDZ drug levels in long-term clinical outcomes in a real-world cohort. Methods: Patients with moderate to severe ulcerative colitis (UC) and Crohn's disease (CD) from a tertiary IBD referral center at the University Hospital Augsburg, Germany, were enrolled in this single-center retrospective data analysis. Clinical and endoscopic data were collected at month 6, month 12, and at the last time of follow-up, and outcomes were correlated with VDZ levels at week 6. Results: This study included 95 patients, 68.4% (n = 65) with UC, 24.2% (n = 23) with CD, and 7.4% (n = 7) with indeterminate colitis (CI). Patients with a mean VDZ treatment time of 17.83 months ± 14.56 showed clinical response in 29.5% (n = 28) and clinical remission in 45.3% (n = 43) at the end of the study. Endoscopic response occurred in 20.0% (n = 19) and endoscopic remission in 29.5% (n = 28) at the end of the study. The sustained beneficial effect of VDZ was also reflected in a significant change in biomarker levels. VDZ trough level at week 6 was determined in 48.4% (n = 46) with a mean of 41.79 µg/mL ± 24.58. A significant association between VDZ level at week 6 and both short and long-term outcomes could not be demonstrated. However, numerically higher VDZ levels were seen in patients with endoscopic and clinical improvement at month 6 and at the time of last follow-up. Conclusions: This study demonstrated efficacy and safety for VDZ in a real-world cohort. Although, for some parameters, a clear trend for higher VDZ levels at week 6 was seen, the efficacy of VDZ was not significantly correlated to VDZ level at week 6, which questions the predictive value of VDZ levels in the real world.

Background: COVID-19 is a viral disease caused by severe acute respiratory syndrome corona virus 2 (SARS-CoV-2), first described in 2019, with a significant impact on everyday life since then. In December 2020, the first vaccine against COVID-19 from BioNTech/Pfizer was approved for the first time. However, little is known about the immune response to vaccination in patients with inflammatory bowel disease (IBD) and immunomodulators or biologics. The aim of our study was to investigate antibody response to SARS-CoV-2 vaccination in patients with IBD receiving immunomodulators or biologics compared to healthy controls. Methods: This was a single-center study with a retrospective observational design. Seventy-two patients with ulcerative colitis or Crohn's disease were included. Matching data from 72 healthy employees of our hospital were used as the control group. Data were matched by propensity score to patients with IBD. Blood samples were taken from both groups for antibody response, and both groups received an accompanying questionnaire. Results: Sixty-five (90.3%) patients of the IBD group reported taking immunomodulatory therapy. The mean antibody level for all IBD patients was 1,257.1 U/mL (standard deviation [SD] 1,109.626) in males and 1,500.1 U/mL (SD 1142.760) in female IBD patients after full vaccination. Compared to the healthy group, reduced antibody response could be detected (IBD group 1,383.76 U/mL SD 1,125.617; control group 1,885.65 U/mL SD 727.572, p < 0.05). In this group, blood samples were taken with an average of 61.9 days after the first vaccination. There was no vaccination failure in the IBD group after 2 vaccinations. After the first vaccination, side effects, including muscle pain, pain at the injection site, and fatigue, were reported more often in IBD patients than in the control group (total symptoms IBD group 58.3%, control group 34.5%, p < 0.007). The opposite occurred after the second vaccination when side effects were higher in the control group (total symptoms IBD group 55.4%, control group 76%, p = 0.077). There was a trend to a reduced immune response in elderly patients. Disease duration and concomitant immunomodulatory therapy (TNF-alpha blockers, interleukin inhibitors, integrin inhibitors, methotrexate, or azathioprine) had no impact on the immune response. However, longer time to last medication given and time passed to vaccination in patients with IBD seems to have a positive impact on antibody levels. Conclusion: Overall, we could show a high antibody response to vaccination with COVID-19 in all patients with IBD after 2 vaccinations. Vaccination was well tolerated, and no other adverse events were detected. Concomitant immunomodulatory therapy (TNF-alpha blockers, interleukin inhibitors, integrin inhibitors, methotrexate, or azathioprine) had no impact on seroconversion. Further evaluation of antibody titers over time is mandatory to detect early the need for re-vaccination in these patients. [ABSTRACT FROM AUTHOR]

Background and study aims Endoscopic resection is a curative treatment option for large nonpedunculated colorectal polyps (LNPCPs). Endoscopic submucosal dissection (ESD) allows en bloc resection but ESD experience is still limited outside Asia. The aim of our study was to evaluate the role of ESD in the treatment of early rectal neoplasia in a European center. Patients and methods 330 patients referred for endoscopic resection of rectal LNPCPs were included prospectively. Results ESD was performed for 302 LNPCPs (median diameter 40 mm). Submucosal invasive cancer (SMIC) was present in 17.2 % (n = 52). SMIC was associated with Paris type (54.5 % among type 0-Is lesions, 100 % of 0-Is-IIc type, 0 % of 0-IIa, 14.9 % of 0-IIa-Is, and 59.3 % of 0-IIa-IIc type; P < 0.001) and with surface pattern (71.4 % among nongranular plus mixed surface lesions, 17.9 % of lesions with granular surface and nodule ≥ 10 mm). For SMICs, resection rates were en bloc 81.4 %, R0 65.1 %, and curative 30.2 %. Curative resection rate improved from 13.6 % to 47.6 % over the study period (P = 0.036). The reason for 83.3 % (25/30) of noncurative resections was submucosal invasion exceeding 1000 µm. For benign lesions (n = 250, 82.8 %), the R0 resection increased from 55.2 % to 84.8 % over the study period (P < 0.001). Recurrence rate was 4.8 %, bleeding rate 5.2 %, and perforation rate 0.8 % (all complications managed conservatively). Median follow-up was 35 months. Conclusions The majority of rectal LNPCPs are benign lesions. ESD offers high R0 resection and low recurrence rates but EMR may be appropriate. In lesions with a risk for SMIC, ESD should be offered to achieve R0 resection. Despite high rates of R0 resection the curative resection rate of ESD for rectal SMIC is < 50 %. Pretherapeutic lesion selection needs improvement. [ABSTRACT FROM AUTHOR]

We present the case of a 73-year-old female patient with acute esophageal necrosis, or black esophagus, and consecutive distal esophageal perforation. Additionally, the patient had the rare coincidence of duodenal necrosis or black duodenum. Black esophagus is usually diagnosed endoscopically and is characterized by a circular necrosis of the esophagus with abrupt normalization at the gastroesophageal junction. Black esophagus is a rare cause of symptoms of upper gastrointestinal bleeding with a mortality rate of up to 30 %. Complications include esophageal perforation and esophageal stricture formation.

Esophageal squamous cell carcinoma (ESCC) remains the most common esophageal cancer in the world, though a rising incidence of esophageal adenocarcinoma could be seen during the last decade in the western world. There are several known risk factors for ESCC, such as smoking, alcohol consumption, radiation or others. As there is a risk of lymph node metastasis already in early stages, early endoscopic detection is crucial for curative endoscopic treatment options. Therefore, newest technical improvements such as enhancement techniques or virtual chromoendoscopy are helpful for the diagnosis of mucosal carcinoma. Lugol's iodine remains the gold standard to detect early esophageal cancer, however, it should be combined with these newer techniques. For the prediction of invasion depth, a new classification was developed by the Japan Esophageal society. By using magnifying endoscopy and Narrow Band Imaging, the microvascular morphology allows a prediction of invasion depth of early squamous cell carcinoma. Endoscopic resection is suitable for patients with early-stage ESCC (m1-m2), because of the low risk of lymph node metastasis. EMR should be performed if the lesion is smaller than 15 mm, because a R0 resection can be achieved. Larger lesions (>15 mm) should be resected via endoscopic submucosal dissection to reach an en bloc resection, a lower recurrence rate and a R0 situation.
