Update on trends in childhood tuberculosis.

Area of Science:

• Pediatrics
• Infectious Diseases
• Public Health

Background:

• Tuberculosis (TB) presents significant morbidity and mortality in children, with diagnosis and treatment posing challenges.
• Recent research and clinical trials are increasing focus on pediatric TB, improving management and identification.
• Global initiatives aim to end the TB epidemic by 2030-2035, necessitating advancements in child-specific strategies.

Purpose of the Study:

• To review recent advancements in the diagnosis and treatment of pediatric tuberculosis (TB).
• To highlight improvements in case identification and management of both drug-susceptible and drug-resistant TB in children.
• To discuss emerging therapeutic strategies and diagnostic tools for childhood TB.

Main Methods:

• Review of recent scientific literature and clinical trial data on pediatric TB.
• Analysis of diagnostic methods, including immunological assays and molecular diagnostics like Xpert MTB/RIF.
• Evaluation of current and emerging treatment regimens for drug-susceptible and drug-resistant TB in children.

Main Results:

• Novel diagnostic approaches, such as M. tuberculosis-specific CD4/CD8 cell stimulation and improved sampling methods, enhance case identification.
• Xpert MTB/RIF offers improved detection of M. tuberculosis in clinical samples.
• Paediatric-friendly dispersible fixed-drug combinations are available for drug-susceptible TB, improving adherence.
• Research into newer, effective drugs for drug-resistant TB in children is ongoing.

Conclusions:

• Significant progress has been made in pediatric TB diagnosis and treatment, with more child-friendly options emerging.
• Continued research and implementation of effective national TB programs are crucial, especially in high-burden settings.
• Addressing drug-resistant TB in children requires further investigation and adaptation of adult treatment protocols.
