Introduction: Hepatitis B virus (HBV) and HIV Co-infection affects 2.7 million people, which is equivalent to 5-10% of people living with HIV. This comorbidity changes the natural history of both pathologies. In Peru, the characteristics of HIV patients according to the different serological patterns of HBV are not well defined. Methods: Secondary analytical cross-sectional study of a database obtained by reviewing medical records in two public hospitals in Lima, Peru. People aged 18 years or older with a confirmed diagnosis of HIV who started/restarted highly active antiviral treatment (HAART) 2016-2017 were included. Surface antigen (HBsAg), Anti-surface antigen (anti-HBs), Anti-core antigen, and serological patterns according to these markers were evaluated. Crude and adjusted Prevalence Ratios (aPR) were obtained for the different characteristics using Poisson regression with robust variance. Results: 429 patients were included with a prevalence of HBsAg of 4.43% (2.69% -6.83%). There was significant association between HBsAg prevalence and intravenous drugs use (aPR: 1.70; 95% CI 1.07-2.68), transaminasemia (aPR: 3.69; 95% CI 2.97-4.57) and prior HAART use (aPR: 0.52; 95% CI 0.35-0.77). 129 patients without active infection were evaluated for anti-HBs, with 8.53% (4.33% -14.74%) being positive. Association was found with age ≥30 years (aPR: 5.09; 95% CI 2.72-9.54), previous HAART use (aPR: 3.01; 95% CI 1.84-4.93) and viral load ≥1000 copies / ml (aPR: 0.29; 95% CI 0.13-0.63). Conclusions: Intravenous drug use and transaminasemia were associated with a higher prevalence of active infection (HBsAg +), while previous use of HAART showed a lower prevalence. Age ≥30 years and HAART were associated with a higher prevalence of anti-HBs in patients without active infection, while viral load ≥1000 copies/ml was associated with lower prevalence.
