Azmoudeh-Ardalan F, Khodabandehloo M. Prevalence of Overt and Occult Hepatitis B Virus Infection among HIV-Positive People Referring to Consultation Center for Behavioral Diseases, Kurdistan Province, Iran. IBJ 2021; 25 (6) :434-440

Background: Based on evidence, human immunodeficiency virus (HIV) and hepatitis B virus (HBV) have common transmission routes; co-infection of HBV/HIV can dramatically increase disease progression. The present study aimed to determine the prevalence of overt HBV infection and occult hepatitis B virus infection (OBI) in HIV-positive people. Methods: In this descriptive study, whole blood samples were collected from 184 HIV-positive subjects referring to the Consultation Center for Behavioral Diseases, Sanandaj, Iran, during 2014 to 2016. ELISA was used for the determination of HBV serologic markers (hepatitis B surface antigen [HBsAg] and antibodies to hepatitis B virus core antigen [anti-HBc]). To evaluate OBI, DNA was extracted only from HBsAg-negative and anti-HBc-positive samples and tested for HBV DNA by real-time PCR. Test results and patients’ data were analyzed by SPSS software. Results: The mean age of the study population was 39.2 ± 9.4 (SD) years, of whom 140 (76%) were male. Overall, 43 (23.3%) samples were positive for HBsAg (overt HBV infection), and 50 (27.2%) for anti-HBc. Among 31 HBsAg-negative and anti-HBc-positive samples (suspected OBI), one (3.2%) sample was positive for HBV DNA (verified seropositive OBI). HBV infection was higher among males (n = 37; 86.05%), jobless people (n = 23; 53.49%), and those with an injection HIV transmission route (n = 32; 74.43%).Conclusion: We observed a high prevalence of overt HBV and one OBI among the study population. A serologic marker such as anti-HBc indicates resolved or past HBV infection. Molecular screening for HBV is valuable for the management of HIV-infected people.
