Important of Angiopoietic System in Evaluation of Endothelial Damage in Children with Crimean-Congo Hemorrhagic Fever
Özet
Background: Crimean-Congo hemorrhagic fever (CCHF) causes endothelial activation and dysfunction by affecting the endothelium directly or indirectly. In maintaining the vascular integrity, vascular endothelial growth factor (VEGF-A) and its receptor (VEGFR1) and angiopoietin-2 (Ang-2) and its receptor (Tie-2) are very important mediators. For this reason, we aimed at studying the association of Ang-2 and VEGF and their receptors Tie-2 and VEGFR1 with CCHF infection. Methods: Thirty one CCHF patients and 31 healthy controls (HC) were included in the study. CCHF patients were classified into 2 groups in terms of disease severity (severe and nonsevere). VEGF-A, VEGFR1, Ang-2 and Tie-2 levels were measured in all groups. Result: Serum levels of Tie-2, Ang-2, VEGF-A and VEGFR1 were significantly increased in CCHF patients compared with the HC. Furthermore, serum Tie-2, Ang-2, VEGF and VEGFR1 levels were found to be significantly higher in the severe group than in the nonsevere and HC groups (P < 0.05 and P < 0.001, respectively). Also, Tie-2, Ang-2, VEGF-A and VEGFR1 levels were significantly higher in the nonsevere group than in the HC group (P < 0.05). Conclusion: Having statistically significant higher Ang-2, Tie-2, VEGF-A and VEGFR1 levels in the severe group when compared with the other groups suggested that VEGF-related Ang-2/Tie-2 system played a critical role in the pathogenesis of the disease, and these markers could be used as the severity criteria.
