Tuberculosis exposure, infection and disease among children with medical comorbidities

Area of Science:

• Pediatrics
• Infectious Diseases
• Medical Comorbidities

Background:

• Tuberculosis (TB) poses a significant health risk to children, particularly those with pre-existing medical conditions.
• Understanding the spectrum of TB (exposure, infection, disease) and associated comorbidities in pediatric populations is crucial for effective management.

Purpose of the Study:

• To evaluate the treatment outcomes and safety of tuberculosis medications in children with various medical comorbidities.
• To identify the most prevalent comorbidities among children diagnosed with active TB disease.

Main Methods:

• Retrospective analysis of 69 children treated for tuberculosis exposure, infection, or disease.
• Categorization of TB status and documentation of co-existing medical conditions.
• Assessment of adverse events, therapy completion rates, and mortality.

Main Results:

• The study included children with TB exposure (7), infection (40), and disease (22).
• Common comorbidities in children with TB disease included malignancy (23%), cyanotic heart disease (18%), hemoglobinopathies (18%), and autoimmune disease (14%).
• Tuberculosis medications were well-tolerated, with 96% experiencing no adverse events and 98% completing therapy. Two children (9%) with TB disease died.

Conclusions:

• Tuberculosis treatment in children with medical comorbidities is generally safe and effective, with high adherence and low adverse event rates.
• Despite treatment advancements, TB disease remains a critical threat, evidenced by mortality in a subset of vulnerable children.
• Identifying and managing comorbidities is essential for optimizing TB care in pediatric patients.
