Background: To estimate seropositivity of hepatitis A virus Ig G antibody (HAV Ig G antibody) in 11 to 15 years aged children in Vijayawada.Methods: The study group includes 265 consecutive children aged 11 to 15 years attending GGH, Vijayawada and had a blood sample taken for any reason. The serum samples collected were screened for Anti HAV IgG antibody using commercially available Elisa kit (WANTAI). Information related to various socio demographic factors also were elicited by interview method. All the Anti-Hepatitis A virus IgM antibody positive individuals list are collected from 1stJuly 2015 to 1st august 2017 and were categorized based on age and analysed.Results: The total seropositivity against Hepatitis A virus is 71%. The number of children in the urban population showing IgG antibodies is lower compared to that of rural population (p value-0.028). The highest number of Hepatitis A virus infected population (positive IgM) is between 10-14 years (50), followed by 15-19 years (45) and 5-9 years (43). This shows that there is increased risk of infection in the older age group and there is a shift to 2nd and 3rd decade (p value – 0.045).Conclusions: The seropositivity of HAV IgG antibody in children aged 11-15 years is 71% in Vijayawada. Seroprevalence in the nearby area, Chennai, ten years back was found to be 95% by 12 years of age. This indicates there is a shift from high to intermediate endemicity in Vijayawada. There is need for vaccination in the susceptible individuals.
Hemolytic disease in the newborn (HDN) as a cause of early jaundice is mostly due to Rh (D), ABO incompatibility, and rarely due to other minor blood group incompatibility. We report case of Rh anti-E isoimmunization presenting as significant unconjugated jaundice within the 24 h of life. Baby presented with severe jaundice and anemia on day 1 of life. Baby was treated with intensive phototherapy, double volume exchange transfusion (DVET), and intravenous immunoglobulins. On evaluation, both mother and baby had O positive (Rh) blood group; however, the infant showed evidence of severe hemolysis. Positive direct Coombs test (DCT) and 11 cell antibody panel showed anti-E antibodies. This case highlights the importance of early identification and evaluation of HDN in the absence of Rh(D) and ABO incompatibility and possibility of severe hemolysis in Rh anti-E isoimmunization needing DVET.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
