  • Gastrointestinal manifestations in patient with Common Variable Immunodeficiency Syndrome (CVID): A Case Report

    A 57 yo male with a background history of common variable Immunodeficiency syndrome (CVID) on Immunoglobulin Infusion (Kiovig) 40mg three weekly was referred for investigation of diarrhoea and follow up from previous history of colonic polyps. Colonoscopy showed an irregular looking ileocaecal valve (ICV) with an adjacent flat polyp (Paris IIa). Biopsies showed low grade dysplasia. There was also a duodenal polyp noted on gastroscopy and biopsy again showed low grade dysplasia. In light of the findings of upper and lower gastrointestinal tract polyps, a small bowel capsule endoscopy (SBCE) was arranged. This showed an irregular area of mucosa in the proximal small bowel with significant ulceration and inflammation (Figure 1). There were also multiple scattered lymphagiectasias and lymphoid hyperplasia in the distal small bowel (Figure 2). Anterograde double ballon enteroscopy (ADBE) was subsequently performed to the distal jejunum about 8 weeks after the SBCE. The duodenal polyp seen at gastroscopy was visualised during ADBE (Figure 3). In addition, two diminutive (

  • Efficacy Of Potassium-Competitive Acid Blocker vs Proton Pump Inhibitor as First-Line and Second-Line Treatment for Helicobacter Pylori Eradication

    Introduction: Eradication of H. pylori reduced the risk of gastric cancer by 75%, thus, its therapy with high eradication rates is needed. Nowadays, the success rate of H.pylori eradication regimen (PPI-based) has dropped to less than 75% due to clarithromycin resistance and inadequate gastric acid suppression. Vonoprazan, a Potassium-competitive acid blocker (PCAB) was released for use in first-line and second-line treatment for H.pylori eradication. It shows better acid suppression effect in acid-related disease. Aim: The aim of this study was to compare the efficacy of PCAB and PPI as first-line and second-line treatment for H. pylori eradication. Method: We search the Medline, Google Scholar and Directory of Open Access Journals (DOAJ) databases in October 2019. The study selection process was plotted using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) flow diagram. Results: In studies assessing first-line therapy, 776 patient were using PPI and 965 patient were using PCAB. In first-line therapy, PCAB has higher ITT and PP compared to PPI. According to Sue et al, in PPI group, more patient complain of diarrhea (49 vs 25; p < 0.001). In studies assessing second-line therapy, 1,069 patient were using PPI and 605 patient were using PCAB. Two studies showed no significant differences between PCAB and PPI in second-line therapy, but one study showed PCAB superiority (ITT PPI vs PCAB 85% vs 90% p=0.045; PP PPI vs PCAB 91% vs 96% p=0.008). There is no difference in adverse event between PCAB and PPI. Conclusion: In conclusion, PCAB has higher eradication rate (ITT and PP) compared to PPI as first-line therapy for H.pylori eradication. Further study is still needed in comparing efficacy of PCAB and PPI as second-line therapy. Both therapies were safe and well tolerated.

  • Esophageal cancer in Bobo-Dioulasso (Burkina Faso): epidemiological, clinical, endoscopic and anatomopathological aspects

    Introduction. Our study aims to strengthen the literature on esophageal cancer in Burkina Faso by assessing its endoscopic frequency and describing its epidemiological, anatomical-clinical and endoscopic characteristics. Patients and Methods: This was a descriptive cross-sectional study conducted from January 1, 2015 to June 30, 2018. Included in this study were all patients who had upper gastrointestinal fibroscopy (UGIF) with biopsy, and in whom esophageal cancer was confirmed histologically. The variables studied were: age, sex, main circumstance of diagnosis, endoscopic appearance, and histological type, as well as risk factors. Results: During the study period, 29 cases of esophageal cancer were diagnosed, with an average endoscopic incidence of 8.3 cases/year. The average age was 58.34 years. There were 17 (58.6%) males, or a sex ratio of 1.5. The definite risk factors of alcohol consumption and active smoking were present in 31.0% of patients. The average duration of consultation was 65.8 days, and the main symptom at diagnosis was dysphagia (72.4%). The preferred location was the lower third for nearly three-quarters of tumors; and the budding form was dominant (56.3%). At histology, squamous cell carcinoma was the dominant type (65.5%). Conclusion: This study shows us an increase in the average annual incidence of esophageal cancer in Bobo-Dioulasso. It mainly affects males from the age of 50, with clinical, endoscopic and histological characteristics similar to those found in the literature. The great delay in diagnosis limits the therapeutic options for this cancer with a formidable prognosis.

  • Vulvar lesion in Crohn’s disease: a new case report

    The mucocutaneous manifestations are, with the osteo-articular attacks, the most frequent of the extradigestive attacks of the Crohn’s disease. While some of these events evolve alongside the digestive disease, others evolve on their own. Sometimes they can even precede the appearance of intestinal manifestations by several months, which then poses diagnostic problems. Recto-vaginal fistulas and ovarian involvement in Crohn’s disease have been widely reported in the literature (1; 2). However, there are few series in the literature reporting the genital complications of CD, let alone regarding vulvar lesion. We report a new case of vulvar lesion in Crohn’s disease.
