ABSTRACT
BACKGROUND: Hepatitis B Virus (HBV) co-infection is prevalent among HIV infected individuals because of shared routes and mechanisms of transmission. The multidimensional immunosuppression from HIV infection causes impaired spontaneous recovery from an acute HBV infection, predisposing to chronic infection which is worsened by younger age at infection. Co-infection increases the risk of HBV replication, hepatotoxicity and liver related deaths from Highly Active Antiretroviral Therapy (HAART). The study was undertaken to highlight the burden of co-infection among HIV positive children in Enugu, determine the associated risk factors and compare the effect of co-infection between co-infected and non-co-infected children using liver enzyme and CD4 counts. MATERIALS AND METHODS: A cross sectional study was carried out among HIV positive children attending the Paediatric ARV clinic of the University of Nigeria Teaching Hospital, Ituku-Ozalla. A total of 140 HIV infected children aged 18 months to 15 years were recruited. An interviewer questionnaire was administered. Hepatitis B surface antigen (HBsAg) was determined using Determine test Kit. Baseline and recent CD4 counts/CD4% were retrieved from the patients' folders. RESULTS: Fourteen (10%) were positive for HBsAg. The highest prevalence of HBsAg was observed among children aged 11- 15 years. The higher the socioeconomic class the less likely the HBsAg positivity. Seven (50%) of the co-infected children had elevated baseline ALT compared with 57 (45.2%) of non-co-infected children though the difference was not statistically significant (t = 0.6, P = 0.56). After the initiation of HAART, 10 (76.9%) of the co-infected and 18 (15.1%) of the non-co-infected children had elevated ALT. The baseline median CD4 count among children ≥ 6 years was 230 cells/mm3 and 360 cells/mm3 respectively among the co-infected and non- co-infected, (P = 0.67). However, in children ≤ 5 years, it was 25% and 15 % respectively (P = 0.06). CONCLUSION: HBV co-infection among HIV infected children is common in our environment, and co-infection is associated with impaired immunity and probably liver enzyme derangement.

BACKGROUND: The burden of childhood obesity is increasing in most developing countries particularly in the urban areas owing to globalization; and children with sickle cell anemia (SCA) in such environment do not live in isolation. The study is aimed at determining the prevalence of obesity in younger children with SCA. METHODS: A consecutive recruitment of 58 children with SCA aged between 1 year and 5 years 4 months (subjects) and their age and sex matched controls selected using multistage sampling technique were carried out. The weight and height of the children were obtained using standard equipment. The WHO Anthro and Anthro-Plus software were used for analyzing the nutritional status of the children based on standard deviation (z-scores). The data were analyzed using SPSS version 19.0 while the level of significance was set at p < 0.05. RESULTS: The mean BMI for the subjects was 15.38 ± 1.93 (range from 11.50-20.80) and 17.10 ± 2.28 (range from 13.4-23.20) in the controls. Overweight (z-score > + 1 ≤ 2) and obesity (z score >+2) were recorded in 10 (17.2%) and 2 (3.4%) of the subjects while in the controls overweight and obesity were observed in 16 (27.6%) and 13 (22.4%), respectively (p = 0.000). CONCLUSIONS: Obesity and overweight is becoming prevalent among children with SCA and so awareness and preventive health education about obesity should be created among caregivers of children with sickle cell anemia in our setting to avert its possible complications.
