Abstract:
Background: Several studies reported a high prevalence of vitamin B12 deficiency in some Asian countries and in Asian immigrants living in Western countries. However, there is no data regarding the prevalence of vitamin B12 deficiency in Viet Nam.\r\n', u'Objectives: The aim of this study was to determine the prevalence of vitamin B12 deficiency in patients with upper gastrointestinal symptoms in the Mekong Delta and to investigate the risk factors for vitamin B12 deficiency. \r\n', u'Methods: Blood samples were collected from patients visiting Can Tho General Hospital for upper gastrointestinal endoscopy. Serum vitamin B12 concentration was measured at the University Medical center St Radboud Nijmegen, Netherlands. \r\n', u'Results: Between September and December 2003, 216 patients (80 male, 136 female, mean age 43.2 years) were studied. Ten patients had gastric cancer, 28 peptic ulcer disease/ and 178 gastritis only or no visible pathology. Only 2 patients (0.9%) had clinical vitamin B12 deficiency (<160 pmol/l, whereas 15 patients (7.0%) had sub-clinical vitamin 812 deficiency (160-250 pmol/l). H. pylori positive patients (n=111) were more likely to have para-clinical vitamin B12 deficiency than H. pylori negative patients (odds ratio 3.7~ 95%CI 1.10-12.76). \r\n', u'Conclusions: Vitamin B12 deficiency is uncommon in the Mekong Delta. Helicobacter pylori infection is a risk factor for vitamin B12 deficiency. \r\n', u'
