Adherence to hepatitis A virus vaccination in HIV-infected men who have sex with men.

Although vaccination against hepatitis A virus (HAV) is essential for human immunodeficiency virus (HIV)-infected patients, the uptake of HAV vaccine is reported to be very low. From 2007 to 2012, 912 HIV-infected men in Athens, Greece were screened for exposure to HAV. Two doses of an HAV vaccine were recommended to 569 eligible patients.

Prevalence and titre of antibodies against Hepatitis A virus in HIV-infected men having sex with men in Greece.

Hepatitis A remains a serious vaccine-preventable disease for HIV patients. We tested 897 HIV-infected men having sex with men (MSM) for antibodies against hepatitis A virus (anti-HAV) and measured the geometric mean antibody titres (GMTs) in a group of patients who received a hepatitis A vaccine and in patients with immunity to HAV due to infection in childhood. In all, 320 patients (35%) had positive anti-HAV antibodies.

Hepatitis A vaccination and immunological parameters in HIV-infected patients.

Vaccination against hepatitis A is an important intervention to prevent disease in HIV-patients. There are insufficient data on the association of the response to hepatitis A vaccine with immunological parameters, including subpopulations of T-cells. We studied HIV-infected adults with CD4 T-cells>200 cells/mm(3) who received two doses of hepatitis A vaccine (Havrix or Vaqta).

Adherence to antiretroviral therapy among HIV-infected prisoners.

Adherence, the act of following a course of medication in exactly the manner prescribed, is critical for the success of therapy. Adherence is influenced by many behavioural and social factors and incarceration might be one such factor. This study determined the level of adherence and reasons for non-adherence to antiretroviral therapy among 93 HIV-infected prisoners.
