ABSTRACT
BACKGROUND:
Tuberculosis (TB) is a leading cause of death in patients with human immunodeficiency virus (HIV)/AIDS. About 60% of HIV-positive individuals with latent TB infection (LTBI) develop active TB. Isoniazid preventive therapy (IPT) is recommended by the World Health Organization to prevent the progression of active TB in people living with HIV/AIDS (PLWHA). However, IPT implementation has been limited in some countries like Indonesia. The objective of this study was to assess the effect of IPT administration on the incidence of active TB in HIV patients with latent TB.METHODS:
This was a quasi-experimental prospective cohort study conducted in an academic hospital in Indonesia. Interferon-gamma release assay-positive HIV-TB patients were randomly divided into an IPT group (received 6 months of IPT) and a non-IPT group. The incidence of active pulmonary TB was compared between the two groups after 6 months of follow-up.RESULTS:
Of the 23 eligible patients, 22 were enrolled (10 in the IPT group, 12 in the non-IPT group). The incidence of active pulmonary TB was 0% in both groups. Factors associated with the absence of TB in both groups were the use of antiretroviral therapy for >4 years and a CD4+ T lymphocyte count >200 cells/µL. IPT was found to be safe with minimal adverse effects.CONCLUSIONS:
In this setting, the use of long-term antiretroviral therapy and higher CD4+ counts, rather than just IPT, were the key factors associated with preventing active TB in latent HIV-TB patients. These findings suggest that comprehensive HIV management may be more important than IPT alone for TB control in PLWHA. Further research is needed to optimize TB prevention strategies in this high-risk population.
