Abstract

GOUVEA, Aída F. T. B. et al. The prevalence of hepatitis A antibodies in HIV exposed and/or infected children and adolescents. J. Pediatr. (Rio J.) [online]. 2005, vol.81, n.3, pp. 205-208. ISSN 0021-7557.  http://dx.doi.org/10.1590/S0021-75572005000400006.

OBJECTIVE: To evaluate the prevalence of hepatitis A virus antibodies in HIV-exposed and/or HIV-infected children and adolescents. METHODS: Between September 1996 and August 2002, 352 patients (200 exposed, but not HIV-infected and 152 HIV exposed and infected) were included in this study. These children and adolescents (age ranged between 1 and 14 years) were all followed up at the Pediatric AIDS Clinic of the Federal University of São Paulo (UNIFESP) and had anti-HAV antibodies determined by a commercially available ELISA method (tests for total anti-HAV antibodies and specific IgM antibodies) (Dia Sorin and Radim). Statistical analyses were done with chi-squared and t test. RESULTS: The prevalence of hepatitis A virus antibodies in HIV-infected and HIV-exposed, but uninfected patients was 34% and 19.7%, respectively. We noticed that in the age range between 2 years and 10 years, the group of HIV-infected children presented a higher prevalence of hepatitis A virus antibodies (35.5%) than the group of uninfected children (16.7%) (p = 0.005). In the HIV infected group, children from B and C categories had a prevalence of hepatitis A virus antibodies (40.5%) higher than N and A categories (24.1%) (p = 0.042). Mean age did not differ when children from B and C categories were compared with N and A categories (5.18 and 5.66 years, respectively) (p = 0.617). CONCLUSIONS: The prevalence of hepatitis A virus antibodies in HIV exposed and/or infected children and adolescents between 1 and 14 years old was 26%. Considering the possibility of HIV infection aggravation when associated with hepatitis A virus infection, we suggest that hepatitis A virus inactivated vaccine should be administered to these patients.
