A Comprehensive Review of the Diagnostics for Pediatric Tuberculosis Based on Assay Time, Ease of Operation, and...

Area of Science:

• Public Health
• Infectious Diseases
• Medical Diagnostics

Background:

• Pediatric tuberculosis (TB) presents significant diagnostic challenges, particularly in low- and middle-income countries (LMICs).
• Diagnostic turnaround time (TAT) and operational simplicity are crucial for timely treatment initiation, impacting pediatric TB morbidity and mortality.
• Existing diagnostic methods often struggle to meet the demands of resource-limited settings.

Purpose of the Study:

• To review the evolving landscape of pediatric TB diagnostics, focusing on turnaround time and ease of operation.
• To evaluate traditional, molecular, and emerging biomarker-based diagnostic approaches for TB in children.
• To identify gaps and challenges in current diagnostic strategies for pediatric TB in resource-limited environments.

Main Methods:

• Literature review of diagnostic methods for pediatric tuberculosis.
• Analysis of diagnostic techniques based on turnaround time (TAT) and operational feasibility.
• Examination of traditional methods (microscopy, culture), molecular techniques, biomarker-based approaches, and AI-driven detection.

Main Results:

• Rapid molecular and AI-based methods show promise for improved speed and sensitivity in pediatric TB diagnosis.
• Trade-offs between rapid results, accuracy, and clinical utility require careful consideration.
• Implementation challenges in resource-limited settings, including cost and algorithm gaps, persist.

Conclusions:

• Optimizing pediatric TB diagnostic strategies requires balancing speed, performance, cost, and feasibility.
• Emerging technologies like AI offer potential advancements but face implementation hurdles.
• Further development and strategic implementation are needed to address the global burden of pediatric TB.
