Genotype pattern of H. pylori in gastritis and peptic ulcer disease in relation to normal endoscopic
findings
Genotype pattern of H. pylori (Helicobacter pylori) in gastritis and peptic ulcer disease in relation to normal endoscopic findings
was studied in 206 H. pylori positive dyspeptic patients (male 128, female 78). H. pylori were diagnosed by RUT (rapid urease
test), culture and PCR (polymerase chain reaction). H. pylori positive was considered if any one of the test was positive. Multiplex
PCR assay was done directly from biopsy specimens for genotyping. CagA and Vac A alleles were studied. CagA positive and CagA
negative in three groups are shown in table 1. CagA gene was found to be significantly more frequent in gastritis and peptic ulcer
patients as compared with patients with normal upper GI tract at endoscopy. Association of vac A alleles with gastritis and peptic
ulcer was seen as shown in table 2.

Biography
A S M A Raihan has been working in the department of Gastroenterology, Banga bandhu Sheikh Mujib Medical University, Dhaka, Bangladesh. His research interest is
focused in Irritable bowel syndrome, inflammatory bowel disease, peptic ulcer disease and Helicobacter pylori infection. His important works are profile of ulcerative colitis
in Bangladesh, presented in APDW, 2006, profile of patients of Crohn's disease in Bangladesh, Symptomatic overlap in patients with diarrhoea predominant irritable bowel
syndrome and microscopic colitis in Bangladeshi population and histopathological alteration in post infectious irritable bowel syndrome. He developed a clinical scoring
system to differentiate difficult to diagnose cases of intestinal tuberculosis and Crohn’s disease and presented his work in Asia Pacific Digestive Week, Kobe, Japan in
2016. He has got more than 50 publications and he supervised more than 50 theses.
