Acquired drug resistance during inadequate therapy in a young child with tuberculosis

Area of Science:

• Pediatric infectious diseases
• Mycobacterial genetics
• Antimicrobial resistance

Background:

• Tuberculosis (TB) remains a significant global health challenge, particularly in children.
• Drug resistance in pediatric TB is typically primary (transmitted), but secondary acquisition during treatment is a concern.
• Effective first-line anti-TB therapy is crucial for treatment success and preventing resistance.

Observation:

• A case study of a child with tuberculosis is presented.
• The child received directly observed therapy (DOT) but with inadequate first-line treatment.
• The child developed drug resistance during the course of treatment.

Findings:

• This case demonstrates the possibility of acquiring drug resistance during TB treatment in children.
• Inadequate treatment regimens, even under directly observed therapy, can contribute to resistance.
• Programmatic and clinical factors likely played a role in the observed resistance acquisition.

Implications:

• Highlights the critical need for optimized and adequate first-line treatment regimens in pediatric TB.
• Underscores the importance of monitoring treatment response and drug susceptibility in children.
• Suggests a need for re-evaluation of programmatic strategies to prevent acquired drug resistance in pediatric TB patients.
