Completion of therapy for latent tuberculosis in children of different nationalities

Area of Science:

• Pediatric Infectious Diseases
• Public Health
• Epidemiology

Background:

• Latent tuberculosis infection (LTBI) requires treatment to prevent progression to active disease.
• Understanding treatment completion rates in pediatric populations is crucial for public health strategies.
• Geographic origin may influence adherence to tuberculosis treatment regimens.

Purpose of the Study:

• To evaluate the treatment completion rates of latent tuberculosis infection in children from diverse geographic backgrounds.
• To identify factors associated with treatment non-completion in a pediatric tuberculosis clinic population.
• To compare treatment outcomes across different geographic regions of origin.

Main Methods:

• Retrospective review of prospectively stored data from 545 children with latent tuberculosis.
• Patients were categorized into six geographic regions based on their country of birth.
• Analysis focused on overall therapy completion rates and reasons for non-completion.

Main Results:

• The overall treatment completion rate for latent tuberculosis infection was 54.4%.
• No significant differences in completion rates were observed based on age, duration in the U.S., or tuberculosis exposure.
• Children from Eastern Europe had 0% completion, while Central and South America had 67.9% completion.

Conclusions:

• Treatment completion for pediatric latent tuberculosis infection is suboptimal and varies significantly by geographic origin.
• Parental refusal to initiate medication was a primary reason for non-completion, especially in Eastern European and Asian children.
• Targeted interventions addressing cultural or logistical barriers may improve treatment adherence in diverse pediatric populations.
