Pediatric tuberculosis in rural South Africa--value of directly observed therapy
1Centre for Epidemiological Research, South African Medical Research Council, Mtubatuba, South Africa.
Insights
Community-based directly observed therapy for childhood tuberculosis in South Africa showed high treatment completion rates. HIV-infected children faced worse outcomes, highlighting the need for integrated care.
Area of Science:
- Pediatrics
- Public Health
- Infectious Diseases
Background:
- Childhood tuberculosis (TB) presents significant mortality and morbidity challenges, particularly in resource-limited regions.
- Effective treatment strategies are crucial for improving outcomes in vulnerable pediatric populations.
Purpose of the Study:
- To describe a community-based, directly observed therapy (DOT) strategy for childhood tuberculosis in a rural South African district.
- To evaluate treatment completion rates and identify factors influencing outcomes, including HIV co-infection.
Main Methods:
- A retrospective review of a community-based DOT program implemented in a rural South African health district since 1991.
- Data collection focused on treatment setting, supervision methods, treatment completion, and outcomes stratified by HIV status.
Main Results:
- 75% of diagnosed children with TB were treated within the community.
- 85% of these children successfully completed their TB treatment.
- Supervision involved clinic staff, community health workers, and lay volunteers.
- HIV-infected children experienced higher case-fatality rates and lower treatment completion compared to HIV-uninfected children.
Conclusions:
- Community-based DOT is an effective strategy for managing childhood tuberculosis in resource-poor settings.
- HIV co-infection significantly worsens treatment outcomes for children with TB.
- Integrated management of TB and HIV in children is essential for improving survival and treatment success.
Abstract:
Tuberculosis is a major cause of mortality and morbidity among children in resource-poor settings. A strategy of community-based, directly observed therapy employed in a rural health district in South Africa since 1991 is described. Most children (75 per cent) diagnosed with tuberculosis were treated in the community and most of them (85 per cent) completed treatment. Supervision was either by clinic-based health workers (26 per cent), community health workers (20 per cent), or volunteer lay people (46 per cent). Among children diagnosed with tuberculosis who were also HIV infected, the case-fatality rate was higher than among the HIV uninfected, and a larger proportion of the HIV infected failed to complete treatment.
