Description:Background
We describe tuberculosis (TB) disease among antiretroviral treatment (ART) eligible children living with HIV (CLHIV) in South Africa to highlight TB prevention opportunities.
Methods
In our secondary analysis among 0–12 year-old ART-eligible CLHIV in five Eastern Cape Province health facilities from 2012–2015, prevalent TB occurred 90 days before or after enrollment; incident TB occurred > 90 days after enrollment. Characteristics associated with TB were assessed using logistic and Cox proportional hazards regression with generalized estimating equations.
Results
Of 397 enrolled children, 114 (28.7%) had prevalent TB. Higher income proxy (adjusted odds ratio [aOR] 1.8 [95% confidence interval (CI) 1.3–2.6] for the highest; 1.6 [95% CI 1.6–1.7] for intermediate), CD4+ cell count < 350 cells/µL (aOR 1.6 [95% CI 1.1–2.2]), and malnutrition (aOR 1.6 [95% CI 1.1–2.6]) were associated with prevalent TB. Incident TB was 5.2 per 100 person-years and was associated with delayed ART initiation (hazard ratio [HR] 4.7 [95% CI 2.3–9.4]), malnutrition (HR 1.8 [95% CI 1.1–2.7]), and absence of cotrimoxazole (HR 2.3 [95% CI 1.0–4.9]). Among 362 children with data, 8.6% received TB preventive treatment.
Conclusions
Among these CLHIV, prevalent and incident TB were common. Early ART, cotrimoxazole, and addressing malnutrition may prevent TB in these children.
We describe tuberculosis (TB) in children living with HIV (CLHIV) eligible for HIV treatment in South Africa to highlight opportunities to prevent TB.
We analyzed additional data from our original study of CLHIV who were 0–12 years-old and due to start HIV treatment in five health facilities in Eastern Cape Province from 2012–2015 and assessed characteristics associated with existing and new TB.
Of 397 enrolled children, 114 (28.7%) had existing TB. Children with a higher measure of household income had higher odds of existing TB. CD4+ cell count < 350 cells/µL and malnutrition were also associated with existing TB. There were 5.2 new cases of TB for every 100 child-years. New TB was 4.7 times more likely for children with delayed HIV treatment start, 1.8 times more likely for children with malnutrition, and 2.3 times more likely for children who did not get cotrimoxazole. Among 362 children with data, 8.6% received treatment to prevent TB.
Among these CLHIV, existing and new TB were common. Early HIV treatment, cotrimoxazole, and addressing malnutrition may prevent TB in these children.
