HIV-hepatitis co-infection in a rural community in Northern Nigeria.

INTRODUCTION

HIV, hepatitis B and hepatitis C pose a public health challenge in sub-Saharan Africa and there are only few studies on co-infection of these viruses done in rural areas in Northern Nigeria. This study provides a rural perspective on HIV-hepatitis co-infection in a Northern Nigerian community.

METHODS

this cross-sectional study was carried out amongst people living with HIV/AIDS (PLWHA) in a rural community hospital over a three-month period. Socio-demographic data and other relevant information were obtained from the participants and case notes using an interviewer-administered questionnaire. Hepatitis B surface antigen and antibody to Hepatitis C virus were assayed from serum using enzyme-linked immunosorbent assay (ELISA) kits developed by LabACON®. Chi-square test was used to compare categorical variables and logistic regression modelling was used to determine correlates of co-infection in the population.

RESULTS

a total of 281 individuals participated in the study. The prevalence of Hepatitis B co-infection, Hepatitis C co-infection and triple infection was 6.0%, 14.6% and 1.1% respectively. Using Chi-square test, none of the socio-demographic characteristics, WHO Clinical Stage, viral suppression had significant association with Hepatitis B co-infection, however marital status was significantly associated with Hepatitis C co-infection and level of education was significantly associated with triple infection (p < 0.05). Logistic regression modelling generated no significant results.

CONCLUSION

co-infection of viral hepatitis (particularly Hepatitis C) in PLWHA is common in rural Northern Nigeria, and significant correlates include lack of formal education and being married. There is need for provider-initiated routine counselling and screening of PLWHA for viral hepatitis, with adequate follow-up and treatment of co-infected individuals and Hepatitis B vaccination for those without co-infection.
