Objective: The objective is to establish the frequency of Hepatitis B (VHB) co-infection in HIV outpatients at VitalSalud Health Center in Barranquilla, Colombia. Methods: Two serological tests to diagnose Hepatitis B in our HIV patients were performed: Hepatitis B surface antigen and Anticore type Ig G (anti HBC Ig G). These tests were run between July, 2007 and July, 2009. Results: The tests were applied to 103 HIV patients. There was a prevalence of 3.1% (3 patients) for chronic Hepatitis B. Four patients passed away during the study term, none of them was Hepatitis B positive. Six patients with isolated anti HBc Ig G were detected, and only one of them had a positive viral load for VHB DNA (158 copies/ml). This patient was not taking lamivudine at the time of the test. Conclusions: The prevalence of VHB in our patients is similar to the prevalence reported in our country as a whole. The search for occult hepatitis B was positive, with a low viral load, in one out of 103 of our patients. The strategies for diagnosis of occult hepatitis B in HIV patients under lamivudine treatment require further research.
