HIV-associated tuberculosis in infants, children, and adolescents younger than 15 years: an update on the epidemiology, diagnosis, prevention, and treatment.

Purpose of review: HIV-associated tuberculosis (TB) remains a major driver of morbidity and mortality in children and adolescents younger than 15 years (CLWH). The purpose of this review is to highlight recent findings in the areas of prevention, diagnosis, and treatment of HIV-associated TB in CLWH and to highlight knowledge and implementation gaps.

Recent findings: We found that despite access to antiretroviral therapy (ART), high rates of HIV-associated TB are still reported, and with an unacceptably high mortality. There are no advances in screening for TB, but shorter courses of rifapentine-based TB preventive therapy are becoming available. The use of algorithms in TB diagnosis can potentially simplify the therapeutic decision making. There are more data supporting the use of dolutegravir (DTG) with rifampicin and a need to study unadjusted DTG especially in the youngest children. Short course therapy for nonsevere pulmonary TB is currently implemented and programmatic outcome should be studied in CLWH. Low uptake of ART and poor suppression remains an important driver of HIV-associated TB.

Summary: Although screening and diagnosis remains challenging, there are several advances in the prevention and treatment of HIV-associated TB. Effective implementation of these strategies is needed to advance the outcomes of CLWH.
