Summary

The aim of this study is to compare the effectiveness of two vaccination strategies against Hepatitis B virus (HBV) in subjects already infected with human immunodeficiency virus (HIV). Researchers plan to determine the optimal vaccination strategy for achieving protective immunity to HBV infection in HIV-infected adults attending Mulago Hospital's HIV care clinic. Primary objectives are to assess: 1. The role of CD4-cell count and HIV viral loads on the HBV vaccine response. 2. The role of highly active antiretroviral therapy (HAART) on the HBV vaccine response. The secondary objective is to evaluate whether lack of HAART is associated with high rates of loss to follow-up.

Detailed description

This is an interventional study in which researchers will recruit HIV positive individuals who do not have hepatitis B (HBV negative) in order to assess the effectiveness of a hepatitis B vaccine in 2 subgroups: 1. Those who have received less than 3 months treatment, or no treatment, with highly active antiretroviral drugs (HAART naive). 2. Those who have received at least 3 months of treatment with highly active antiretroviral drugs (HAART exposed). All study participants will receive vaccination against HBV. There will be 6-12 clinic visits depending on 1) whether or not the participant responds to the standard 3-dose vaccination protocol and 2) whether he or she suffers a clinical condition or vaccine related adverse event that would call for postponement of the next vaccine dose. The first visit will be to determine if the participant is eligible for the study. If eligible, the participant will receive one dose of vaccine at each of the following three visits. The fifth visit will be to collect blood to determine whether the participant has responded to the 3-dose vaccination protocol. The sixth visit will be to discuss the outcome of the vaccination with the participant. Participants who respond favorably to the 3-dose vaccine protocol will exit the study at this point. However, if a participant fails to respond to the initial 3-dose vaccine protocol, he or she may restart the regimen and receive another 3 doses of vaccine following the same schedule as before but off protocol. Participants will be reimbursed for travel costs to and from the clinic for scheduled clinic visits.
