Insights
Improving childhood tuberculosis (TB) treatment outcomes in Nigeria requires early diagnosis and focused care. Younger children (0-4 years) and those with HIV had poorer outcomes, highlighting areas for intervention.
Area of Science:
- Pediatrics
- Infectious Diseases
- Public Health
Background:
- Tuberculosis (TB) remains a significant global health challenge, particularly in children.
- Understanding factors influencing treatment success in pediatric TB is crucial for effective intervention strategies.
- Nigeria faces a substantial burden of childhood TB, necessitating localized research.
Purpose of the Study:
- To determine the case category distribution of childhood TB in Nigeria.
- To identify clinical and demographic factors associated with varying treatment outcomes in pediatric TB patients.
- To inform targeted interventions for improving TB management in children.
Main Methods:
- Retrospective cohort study design.
- Review of medical records for children aged 0-14 years diagnosed with TB in three Nigerian states in 2015.
- Analysis of case categories, demographic data, clinical factors, and treatment outcomes.
Main Results:
- A total of 724 childhood TB cases were analyzed, with 30.4% in children aged 0-4 years.
- Overall TB treatment success rate was 83.0%, but lower in younger children (77.7% vs 85.3% in 5-14 years).
- Factors linked to unsuccessful outcomes in children aged 0-4 years included male sex, HIV coinfection, and clinical diagnosis methods.
Conclusions:
- Early and accurate diagnosis is essential for improving pediatric TB treatment success.
- Specialized training for healthcare workers on childhood TB and TB-HIV co-management is recommended.
- Effective adherence counseling for caregivers is vital for successful treatment outcomes.
Objectives:
Understanding the factors that influence tuberculosis (TB) treatment outcomes in children is key to designing interventions to address them. This study aimed to determine the case category distribution of childhood TB in Nigeria and assess which clinical and demographic factors are associated with different treatment outcomes in childhood TB.
Materials And Methods:
This was a retrospective cohort study involving a review of medical records of children (0-14 years) with TB in 3 states in Nigeria in 2015.
Results:
Of 724 childhood TB cases registered during the review period, 220 (30.4%) were aged 0-4 years. A high proportion of patients had pulmonary TB 420/724 (58.0%), new TB infection 713/724 (98.5%), and human immunodeficiency virus (HIV) coinfection 108/724 (14.7%). About 28% (n = 201) were bacteriologically diagnosed. The proportion of TB treatment success was 601/724 (83.0%). Treatment success was significantly higher in children aged 5-14 years than those 0-4 years (85.3% vs 77.7%, P = .01). Factors associated with unsuccessful outcomes in patients aged 0-4 years are male sex (adjusted odds ratio [aOR]: 1.2), HIV-positive status (aOR: 1.2), and clinical method of diagnosis (aOR: 5.6).
Conclusions:
Efforts should be made to improve TB treatment outcomes in children by ensuring early and accurate diagnosis, focused training of health workers on childhood TB-HIV care, and effective adherence counseling of caregivers.
