C-reactive protein for pulmonary tuberculosis screening and treatment response monitoring in children

Area of Science:

• Pediatric infectious diseases
• Biomarker research
• Public health in developing nations

Background:

• Tuberculosis (TB) remains a significant health challenge in children, particularly in resource-limited settings.
• Accurate diagnostic tools and effective treatment monitoring are crucial for managing pediatric TB.
• C-reactive protein (CRP) is an inflammatory marker with potential applications in infectious disease management.

Purpose of the Study:

• To evaluate C-reactive protein (CRP) as a diagnostic screening tool for tuberculosis (TB) in Kenyan children.
• To assess the utility of CRP in monitoring the response to TB treatment in pediatric patients.
• To investigate the correlation between CRP levels and TB diagnosis and treatment progression.

Main Methods:

• Prospective study involving children suspected of having TB in Kenya.
• Measurement of serum C-reactive protein (CRP) levels at diagnosis and during TB treatment.
• Statistical analysis to compare CRP levels between TB-positive and TB-negative children and to assess changes during treatment.

Main Results:

• CRP levels did not significantly differ between children with and without TB at the time of diagnosis.
• Median CRP levels showed a significant decrease during TB treatment in both confirmed and unconfirmed TB cases (p=0.03 and p=0.002, respectively).
• The observed reduction in CRP levels suggests a positive response to anti-TB therapy.

Conclusions:

• C-reactive protein (CRP) demonstrates suboptimal performance as a standalone diagnostic marker for TB screening in children.
• CRP shows promise as a valuable biomarker for monitoring treatment response and therapeutic efficacy in pediatric TB patients.
• Further research may refine the role of CRP in the comprehensive management of childhood TB.
