A Comparative Study Between Cytomegalovirus Immunoglobulin M-Positive and CMV Immunoglobulin M-Negative Biliary Atresia in Infants Attending a Tertiary Care Hospital in Bangladesh / 대한소아소화기영양학회지

Purpose@#Perinatal cytomegalovirus (CMV) infection can lead to biliary atresia (BA) in different entities. This study aimed to compare the clinical, hematological, biochemical, and histological features of infants with BA based on their CMV immunoglobulin M (IgM) status at presentation. @*Methods@#This cross-sectional descriptive study was carried out between January 2019 and June 2020 at the Department of Pediatric Gastroenterology and Nutrition at the Bangabandhu Sheikh Mujib Medical University (BSMMU) in Dhaka. Forty-three patients with BA were selected purposively and categorized into either the CMV IgM-positive or CMV IgM-negative BA group. Categorical variables were compared using Fisher’s exact test and chi-square tests, while the Student’s t-test and Mann–Whitney U-test were used to compare continuous variables. For all statistical tests, a p-value <0.05 was considered statistically significant. @*Results@#Thirty-three (76.7%) of the cases were between 2 and 3 months of age on admission.The clinical, hematological, and biochemical parameters did not differ significantly between the CMV IgM-positive and CMV IgM-negative BA groups. Most (50.0%) of the CMV IgMpositive cases had fibrosis stage F2, while 43.5% of the CMV IgM-negative cases had fibrosis stage F3, with no significant difference between the groups (p=0.391). @*Conclusion@#Our data shows no significant distinction between CMV IgM-positive and CMV IgM-negative BA, suggesting that CMV does not contribute to BA pathogenesis.

Wilson's Disease in Bangladeshi Children: Analysis of 100 Cases / 대한소아소화기영양학회지

PURPOSE: To evaluate clinical and laboratory profile of Wilson's disease (WD) in children. METHODS: This cross sectional study was conducted at Bangabandhu Sheikh Mujib Medical University Hospital. Bangladesh, over a period of 3 years. One hundred consecutive children of WD between 3 to 18 years of age were evaluated. RESULTS: Mean age was 8.5+/-1.5 years. Male female ratio was 2:1. Ninety-one percent of patients were Muslim and 9% Hindu. A total of 53% cases of hepatic WD presented between 5 to 10 years of age and most of the neurologic WD manifested in 10-15 years age group. Sixty-nine children presented only with hepatic manifestations, 6 only with neurological manifestations, 14 with both hepatic and neurological manifestation, 10 children was asymptomatic and 1 patient presented with psychiatric features. WD presented as chronic liver disease (CLD) in 42%, CLD with portal hypertension in 34%, acute hepatitis in 20% and fulminant hepatic failure in 4% cases. Stigmata of CLD were found in 18% patients. Keiser-Fleischser ring was found in 76% total patients. Elevated serum transaminase was found in 85% cases, prolonged prothrombin time in 59% cases and hypoalbuminaemia in 53% cases. A total of 73% patients had low serum ceruloplasmin, basal urinary copper of >100 microg/day was found in 81% cases and urinary copper following penicillamine challenge of >1,200 microg/day was found in 92% cases. CONCLUSION: Majority of studied WD children presented with hepatic manifestation of which 76% presented with CLD. Any child presented with jaundice after the age of 3 years should be investigated for WD.

Ulcerative colitis in infancy

Ulcerative colitis [UC] is a chronic idiopathic inflammatory disorder of colon. Frequency of UC is gradually increasing over few years worldwide. Prevalence is 35 to 100/100 000 people in USA, 1% of them are infants. UC develops in a genetically predisposed individual with altered intestinal immune response. An eight-month-old girl presented with loose bloody stool, growth failure, and moderate pallor. The girl was diagnosed as a case of UC by colonoscopy and biopsy. Treatment was thereafter started with immunosuppressive drugs. After initial induction therapy with parenteral steroid and infliximab, the patient is now on remission with azathioprine and mesalamine. UC is rare in Bangladesh, especially in children, and it is rarer during infancy. Several conditions like infective colitis, allergic colitis, Meckel's diverticulitis, Crohn's disease, etc. may mimic the features of UC. So, if a child presents with recurrent bloody diarrhea, UC should be considered as differential diagnosis
