New markers in pelvic inflammatory disease.

Area of Science:

• Gynecology
• Infectious Diseases
• Biomarker Discovery

Background:

• Pelvic inflammatory disease (PID) is a common reproductive-age infection with variable symptoms, making clinical diagnosis difficult (87% sensitivity, 50% specificity).
• Early and accurate PID diagnosis is crucial to prevent severe sequelae.
• Identifying reliable biomarkers can significantly improve diagnostic accuracy and patient outcomes.

Purpose of the Study:

• To identify biological factors for reliable and sensitive early diagnosis of PID.
• To correlate biomarker expression with PID severity.
• To evaluate novel biomarkers, including Growth arrest-specific 6 (Gas6) and its receptor sAxl, for enhanced PID detection.

Main Methods:

• Evaluation of potential biomarkers including Pentraxin 3 (PTX3), E-cadherin, myeloperoxidase, stromal cell-derived factor 1 (SDF-1), and MMP-9/MMP-2 ratio.
• Assessment of Growth arrest-specific 6 (Gas6) and soluble tyrosine kinase receptor Axl (sAxl) for diagnostic sensitivity.
• Analysis of PTX3, D-dimer, and YKL-40 concentrations for predicting clinical course.
• Investigation of single nucleotide polymorphisms (SNPs) in myeloperoxidase and SDF-1 genes.

Main Results:

• Growth arrest-specific 6 (Gas6) combined with its receptor sAxl achieved 92% sensitivity, surpassing other tested markers.
• PTX3, D-dimer, and YKL-40 concentrations demonstrated predictive value for PID clinical course.
• Myeloperoxidase SNP -463 G/A and SDF-1 SNP 801 G/A may influence biomarker expression in PID, though SNPs were not linked to PID development.

Conclusions:

• Gas6/sAxl offers a highly sensitive biomarker strategy for PID detection.
• Specific biomarkers can predict PID progression, aiding clinical management.
• Further research into genetic variations may refine understanding of PID pathogenesis and biomarker behavior.
