Prevalence and Factors Associated with Hepatitis B Virus Surface Antigen and Human Immunodeficiency Virus Antibodies in Chronic Hemodialysis Patients Followed-Up in Lomé, Togo

Abstract

Introduction: In haemodialysis patients, the risk of acquiring blood-borne viral infections is an important cause of the dialysis’s process. Indeed, viral infections are quite common in chronic haemodialysis patients including those due to viral hepatitis B and HIV. Objective: Determine the prevalence of HIV infection and hepatitis B infection among chronic hemodialysis patients of Togo. Methods: A cross-sectional study was conducted in chronic hemodialysis patients of Togo from January 1st to December 31st, 2016. Sociodemographic and clinical data were collected. Antigen HBs was screened by a rapid immunochromatographic test (SD BIOLINE® HBsAg), and HIV antibodies were detected using a combination of 2 rapid diagnostic test, SD BIOLINE® HIV-1/2 (first step) and TRIDOT test (second step). Results: During the study period, 95 subjects were included. Patient’s age was ranking from 13 to 80 years with a mean of 46.6 years. The sex-ratio (M/F) was 1.8 and a duration average of dialysis was 51.7 months. The aetiologies of the chronic endstage kidney failure were related respectively to a vascular renal disease for 42.1% of the patients, glomerular nephropaty for 34.74%, interstitial nephropaty for 9.47% and hereditary for 3.16%. For 10.53% of the patients, the initial renal disease remained indefinite. Prevalence of antigen HBs and HIV antibodies were respectively 10.5% and 7.4%. The frequency of co-infection HBV and HIV was 1.1%. Conclusion: The rates of HBV infection and HIV infection remain high in chronic hemodialysis in Togo, somewhat which is linked to an endemic aspect of these two viruses in the country. The type of initial renal disease (glomerular) and the vascular way (the central catheters) established the risk factors for the HIV infection while for the infection of HVB no factor was incriminated.
