Children and Adolescents

The 2021 WHO consolidated guidelines on HIV prevention, testing, treatment, service delivery and monitoring provide recommendations based on rapidly evolving evidence of safety and efficacy and programmatic experience using DTG and low-dose EFV in pregnant women and people (including children and adolescents) with TB/HIV coinfection (78).

WHO recommendations on the timing of ART for children and adolescents with TB were updated in 2021 (78). ART should be started as soon as possible within two weeks of initiating TB treatment, regardless of CD4 count, among adolescents and children living with HIV (except when signs and symptoms of meningitis are present). In children and adolescents living with HIV with TBM, ART should be delayed at least 4 weeks after treatment for TBM is initiated and initiated 4–8 weeks after starting TB treatment (see Box 7.3).

Co-trimoxazole is a broad-spectrum antimicrobial medicine that prevents a range of secondary bacterial and parasitic infections in eligible people living with HIV. Daily prophylaxis with CPT prolongs survival and reduces the incidence of comorbidities in children living with HIV. It also reduces the risk of coinfections such as pneumocystis pneumonia in infants exposed to HIV.

Children and adolescents living with HIV have an increased risk of TB exposure, infection, progression to disease, and TB-related morbidity and mortality. This risk is influenced by the degree of immune suppression. Childhood HIV infection is particularly common in settings where antenatal HIV prevalence is high and interventions for prevention of vertical transmission are not implemented widely. In these settings, the prevalence of HIV is particularly high among infants and young children, an age group that is also at risk for TB.
