Diagnosis and Management of Multidrug-Resistant Tuberculosis in Children: A Practical Approach

Area of Science:

• Pediatric Infectious Diseases
• Mycobacteriology
• Global Health

Background:

• An estimated 25,000 children annually develop multidrug-resistant tuberculosis (MDR-TB).
• Diagnosis and appropriate treatment for pediatric MDR-TB remain significantly underachieved.
• While new diagnostics aid bacteriologically confirmed cases, many childhood TB cases lack confirmation, necessitating clinical suspicion.

Purpose of the Study:

• To present a practical framework for selecting MDR-TB treatment regimens for children.
• To highlight the importance of identifying presumed MDR-TB cases through detailed history.
• To address the evolving landscape of MDR-TB therapeutics in pediatric populations.

Main Methods:

• Review of current and emerging MDR-TB treatment strategies, including new and repurposed drugs.
• Consideration of shorter, all-oral, and injectable-free regimens.
• Emphasis on clinical history, including contact with drug-resistant cases and prior TB treatment, for presumed diagnoses.

Main Results:

• Pediatric drug dosing and safety studies for new MDR-TB drugs are nearing completion.
• Outcomes for children receiving MDR-TB treatment are generally favorable.
• Less than 5% of children with MDR-TB are currently diagnosed and treated appropriately.

Conclusions:

• A high index of suspicion and thorough patient history are crucial for diagnosing presumed pediatric MDR-TB.
• The focus must shift towards improving the diagnosis and appropriate treatment of MDR-TB in children.
• Implementing updated, child-friendly MDR-TB treatment regimens is essential for better patient outcomes.
