Molecular Characterization of Hepatitis B Virus among HIV Positive and HIV Negative Pregnant Antenatal Women in Federal Capital Territory Abuja Hospital
Journal Title: Journal of Clinical Immunology & Microbiology - Year 2024, Vol 5, Issue 1
Abstract
A significant contributor to chronic hepatitis, cirrhosis and hepatocellular carcinoma is the Hepatitis B Virus (HBV). Hepatitis B Virus (HBV) is a major cause of Chronic Hepatitis, cirrhosis and Hepatocellular Cancer (HCC). The incidence of HBV-related HCC cases is projected to increase for at least two decades due to the high prevalence of chronic HBV infection throughout the world. The overall aim of this study is to determine the sero-prevalence and molecular characterization of hepatitis B virus among HIV positive and HIV negative antenatal women attending Federal Capital Territory Abuja hospitals. A total number of 302 samples were collected from 302 participants between the ages of 18-55 years. The samples were screened for HIV, HBV, HBV serology markers, using rapid test kits, HBV Viral load and HBV genotyping was carried out using multiplex PCR method and data was analyzed using appropriate tools. Nine tested positive for HIV, 34 tested positive for HBV and 2 tested positive for both HIV and HBV, corresponding to 2.9 % (95% CI; 1.2 – 3.8) prevalence for HIV, 11.3% (95% CI; 8.7 – 13.6) for Hepatitis B and 0.7% for HIV/HBV co-infection. Age 25-35 years old had the highest prevalence of HBV 22(7.3%) followed by those of less than 25 years old 8(2.8%) and 1(0.7%) each for age range 36-45 years, 2(0.7%) and 46-55 years. HBeAb and HBcAb were expressed highest among subject within the age range of 25 – 35 year 14 (41.2%) and 22 (64.7 %,) participants respectively, followed by the age range of less than 25 years 5 (14.7%) and 8 (36.4%), for HBeAb and HBcAb respectively. There was no Hepatitis B envelop antigen (HBeAg) nor Hepatitis B surface antibody (HBsAb) among the study group. Of the 34 samples, 20 (62%) had undetectable viral load, while 14 (38%) had detectable viral load. Genotype E was three times more prevalent among those of 25 years old and above than those less than 25 years old detected (75% and 25%). However, genotype B/E mixed was more expressed (60% of cases) among those less than 25 years old, than those greater than 25 years of age (40%). There was no significant difference in the prevalence of genotype E and B/E serotype between HBV+/HIV-patients and their HBV+/HIV+ counterpart (P=0.08 and P=0.15, respectively). HBV Genotype E single infection viral load was significantly (P=0.01) more expressed among those 25 years of age and above than less than 25 years old (4,354,703 ± 346865 IU/ml versus 55.6 ±28.1 IU/ml). Mixed infection genotype B/E was significantly (P=0.04) more expressed among those less than 25 years of age than those 25 years old and above (730.9 ± 238 IU/ml versus IU/ml versus 91.1 ± 48 IU/ml). There was no significant difference between the mean of HBV Viral load HBV+/HIV- patients and their HBV+/HIV+ counterpart (T-test =0.009; P=0.92). In conclusion FCT is 11.3% prevalence rate of HBV and genotypes E and B/E are in circulation among pregnant women among the pregnant women attending antenatal clinic in FCT hospital in Abuja.
