Synopsis

Antiretroviral therapy (ART) scale-up was associated with a 5-fold decline in annual tuberculosis (TB) incidence rates among people living with HIV (PLWH) in care, dropping from 5,960 to 985 per 100,000 person-years between 2007 and 2012 (p=0.0003). (5902407) ART is associated with a 70-90% decrease in TB incidence rates among treated individuals, though TB incidence during ART remains elevated at 7.3 cases per 100 person-years compared to untreated individuals. (3801095) Longer duration on ART is linked to a reduced risk of incident TB in HIV-infected children, with an adjusted hazard ratio of 0.91 per month on ART (p=0.003). (5454479) A prospective randomized controlled trial in South Africa demonstrated that ART prevents TB in children with HIV, supporting its role in TB prevention. (5454479)
