The Role of National Specialist Societies in Influencing Transformational Change in Low-Middle Income Countries - Reflections on the Model of Implementation for a National Endoscopy Training Programme in Bangladesh.

The British Society of Gastroenterology (BSG) and the Bangladesh Gastroenterology Society (BGS) have collaborated on an endoscopy training programme, which has grown up over the past decade from a small scheme borne out of the ideas of consultant gastroenterologists in Swansea, South Wales (United Kingdom) to improve gastroenterology services in Bangladesh to become a formalised training programme with broad reach. In this article, we document the socioeconomic and historical problems that beset Bangladesh, the current training needs of doctors and how the BSG-BGS collaboration has made inroads into changing outcomes both for gastroenterologists in Bangladesh, but also for the populations they serve.

Prevalence, risk factors and metabolic profile of the non-obese and obese non-alcoholic fatty liver disease in a rural community of South Asia.

INTRODUCTION: Since there is a paucity of data on the epidemiology of the non-alcoholic fatty liver disease (NAFLD), particularly in rural areas in Asia, we undertook such a study among the population of a rural community in Bangladesh with the aims to (1) determine the prevalence of non-obese and obese NAFLD, (2) compare the sociodemographic clinical and metabolic characteristics between non-obese and obese NAFLD subjects, and (3) determine the risk factors of NAFLD and no-nobese NAFLD. METHODS: In this door-to-door survey, clinical examination, anthropometric measurements, biochemical tests and ultrasonography were performed on the adult population (≥18 years) of three villages in Bangladesh. RESULTS: Of 1682, 1353 (80.44%) responded. After the exclusion of 48 subjects for alcohol consumption, HBsAg or anti-hepatitis C virus positivity, 1305 ((mean age 41.28±15.10 years, female 908 (69.6%)) were included in the final analysis. On ultrasonography, among the study population, 57 (4.4%) non-obese, 185 (14.2%) obese and, overall, 242 (18.5 %, (male 23.40%, female 16.4%, p=0. 003)) participants had NAFLD. NAFLD was detected in 57/804 (7.1%) of non-obese and 185/501 (36.93%) obese participants. Among the lean subjects, 24/592 (4.1%) had NAFLD. Among NAFLD subjects, 57 (23.55%) were non-obese, and 53 (22%) had raised alanine aminotransferase. On multivariate analysis, age >40 years, male gender, metabolic syndrome (MS), diabetes mellitus (DM), abdominal obesity, hypertension, dyslipidaemia and obesity were found as the risk factors for NAFLD. There were no differences in sociodemographic characteristics, DM, MS, abdominal obesity, hypertension and dyslipidaemia between non-obese and obese NAFLD (all p>0.05). CONCLUSION: In this community study in Bangladesh, NAFLD was present in 18.5% participants, one-quarter of whom were non-obese. Apart from body mass index, the metabolic profile was comparable between obese and non-obese NAFLD. Public health measures are needed to control and prevent NAFLD and MS and their adverse health consequences.

Translation and Validation of Enhanced Asian Rome III Questionnaires in Bengali Language for Diagnosis of Functional Gastrointestinal Disorders.

BACKGROUND/AIMS: Functional gastrointestinal disorders (FGIDs), diagnosed by symptom-based criteria due to lack of biomarkers, need translatedvalidated questionnaires in different languages. As Bengali, the mother tongue of Bangladesh and eastern India, is the seventh most spoken language in the world, we translated and validated the Enhanced Asian Rome III questionnaire (EAR3Q) in this language. METHODS: The EAR3Q was translated in Bengali as per guideline from the Rome Foundation. The translated questionnaire was validated prospectively on Bengali-speaking healthy subjects (HS, n = 30), and patients with functional dyspepsia (FD, n = 35), irritable bowel syndrome (IBS, n = 40) and functional constipation (FC, n = 12) diagnosed by clinicians using the Rome III criteria. The subjects were asked to fill-in the questionnaire again after 2 weeks, to check for its reproducibility. RESULTS: During translation, the original and the backward translated English versions of the questionnaire demonstrated high concordance. Sensitivity of the Bengali questionnaire to diagnose patients with FD, IBS, FC, and HS was 100%, 100%, 75%, and 100%, respectively, considering diagnosis by the clinicians as the gold standard. On test-retest reliability analysis, Kappa values for FD, IBS, FC, and HS were 1.0, 1.0, 0.83, and 1.0, respectively. The Bengali questionnaire detected considerable overlap of FD symptoms among patients with IBS, IBS among patients with FD, and FD among patients with FC, which were not detected by the clinicians. CONCLUSIONS: We successfully translated and validated the EAR3Q in Bengali. We believe that this translated questionnaire will be useful for clinical evaluation and research on FGIDs in the Bengali-speaking population.

Long-term re-infection rate after Helicobacter pylori eradication in Bangladeshi adults.

BACKGROUND AND AIM: Bangladesh is a developing country with a very high prevalence of Helicobacter pylori infection, which has been ascribed to overcrowding and poor sanitary conditions. It has generally been accepted that the re-infection rate is higher in countries with a high prevalence of H. pylori infection. Short-term follow-up studies support this assumption but no long-term studies are available to confirm or refute this assertion. The present study was aimed to define the long-term H. pylori re-infection rate (6 years after successful eradication) in duodenal ulcer patients. METHODS: In a previous study, 90 patients were successfully eradicated for H. pylori and followed-up for 24 months. 17/90 were found to be re-infected (18% re-infection rate per year in the first 12 months) [Gastroenterology 2001;792-798]. The remaining 73 patients were targeted for long-term follow-up. 26/73 were lost to follow-up; 6 symptomatic patients were tested H. pylori positive in the period between 24 and 60 months post-eradication. The remaining 41 patients were evaluated 72 months after successful eradication. The evaluation included clinical history taking, a (13)C-urea breath test (UBT), and endoscopy. RESULTS: Of the 41 H. pylori-eradicated patients analyzed after 72 months, 16 were H. pylori-positive. If the 6 patients, who were tested positive between 24 and 60 months, are added, the total re-infection cases amount to 22 subjects in the period between 24 and 72 months. Therefore, an overall annual re-infection rate 6 years after eradication of 5.02% can be calculated. Six of the 23 symptomatic patients had duodenal ulcer relapse, 5/6 were H. pylori re-infected and one was H. pylori-negative at 72 months post-treatment. CONCLUSION: The long-term annual H. pylori re-infection rate in Bangladeshi adults is markedly higher than in Western countries but lower than anticipated. In this study, duodenal ulcer relapse is clearly related to H. pylori re-infection.
