Crimean-Congo Hemorrhagic Fever Disease: Relationship Between Clinical Course and Apoptosis

Area of Science:

• Virology
• Immunology
• Pathogenesis

Background:

• Crimean-Congo hemorrhagic fever (CCHF) is a severe zoonotic illness.
• Understanding CCHF pathogenesis is crucial for patient outcomes.

Purpose of the Study:

• To evaluate apoptosis biomarkers in mild vs. severe CCHF.
• To correlate biomarker levels with CCHF disease severity.

Main Methods:

• Adult CCHF patients categorized into mild and severe groups.
• Apoptosis markers (clusterin, TRAIL, caspase-8, cytochrome C, Apaf-1) measured via ELISA.
• Biomarker levels assessed during acute and convalescent phases.

Main Results:

• TRAIL levels were higher in the acute phase for both mild and severe CCHF.
• During the acute phase, severe CCHF showed higher clusterin, TRAIL, caspase-8, and Apaf-1.
• TRAIL levels remained significantly higher in severe CCHF during convalescence.

Conclusions:

• Apoptosis proteins are integral to CCHF pathogenesis.
• Clusterin and TRAIL show potential as indicators of CCHF severity.
• Early detection of these biomarkers may improve clinical management of severe CCHF.
