Prevalence of hepatitis B and C viral co-infection and associated factors with HIV infection in children in South Kivu, Democratic Republic of the Congo.

BACKGROUND: The World Health Organization's (WHO) 2030 goal of eradicating Hepatitis B and C viruses must also include HIV co-infected children. However, data on the prevalence of this condition are lacking in the Democratic Republic of Congo (DRC), which is considered as one of the countries with high-prevalence of these viruses. The need to assess the extent of this co-infection in the children of this country is therefore important in order to capitalize on efforts to improve prevention and management of both infections.

METHODOLOGY: This is a comparative cross-sectional study conducted from February 04, 2015 to September 03, 2019 at 14 General Reference Hospitals with a pediatric HIV management programme in South Kivu province. The study compared the frequency of hepatitis B (HBV) and C (HCV) markers and factors associated with these two viruses in two equal groups: HIV-positive and HIV-negative children. The data were analyzed using the SPSS version 20.0 software and the significance level was set at p-value less than 0.05.

RESULTS: The study involved a total of 594 children, 297 of whom were HIV-positive and 297 negative. HBsAg was found in 8.7% of HIV-positive patients and 0.7% for HCV antibodies. On the other hand, among the HIV-negative patients, the proportion of HBsAg was 0.7% but no cases with anti-HCV antibodies were detected. HIV status increases by 14 times the risk of co-occurring with HBV [OR 14.1 (95% CI: 3.33-60.2); p < 0.001] and this risk is not apparent for HCV (p = 0.297). Multivariate logistic regression showed that history of jaundice in the family (aOR:4.19;95% CI: 2.12-11.59), recent hospitalization (aOR:10.7;95% CI: 6.69-17.2), surgery (aOR: 3.24;95% CI: 1.18-8.92), piercing (aOR: 4.26;95% CI: 1.70-10.7) and transfusion in the last 6 months (aOR: 2.69;95% CI: 1.55-4.67) were significantly associated with higher risk of being HBV- HIV co-infected.

CONCLUSION: This study investigated the importance of hepatitis viral co-infections in HIV-positive children in South Kivu. Particular attention should be paid to prevention and early detection of these co-infections in this population.
