Abstract

Purpose: The most important clinical finding of fibromyalgia syndrome (FMS) is pain. Its etiology has not been fully elucidated. This study was planned to determine the relationship between endocan, ET-1, IL-1, IL-6, IL-8, MCP-1, TNF-a, VEGF-A levels and pain/neuropathic pain in FMS patients.
Materials and Methods: Forty-four FMS patients who met the inclusion criteria and 44 age-matched premenopausal healthy controls were recruited. The fibromyalgia group was evaluated in terms of Visual Analog Scale, Beck Depression Scale, Beck Anxiety Scale, Fibromyalgia Impact Questionnaire and LANSS Pain Scale. Serum endocan, ET-1, IL-1, IL-6, IL-8, MCP-1, TNF-α, and VEGF-A values were determined by the ELISA method. Protein-protein interaction was evaluated by molecular docking analysis. Bioinformatics analysis was performed using the STRING v 11.5 protein interaction tool.
Results: Endocan, ET-1, IL-1, IL-6, IL-8, MCP-1, TNF-α, and VEGF-A were significantly higher in FMS patients than the control group. 24 of 44 patients had neuropathic pain. No correlation was found between pain/neuropathic pain and serum markers levels. High interaction and homology scores of the proteins were defined.
Conclusion: The pain/neuropathic pain relationship of these markers could not be determined, but the calculated binding energies and activities of the proteins provided important clues for future studies.

Fibromiyalji hastalarında nöropatik ağrı ile serum endocan, ET-1, IL-1, IL-6, IL-8, MCP-1, TNF-α, VEGF-A düzeyleri arasındaki ilişki ve moleküler docking sonuçları

Abstract

Amaç: Fibromiyalji sendromunun (FMS) en önemli klinik bulgusu ağrıdır. Etiyolojisi tam olarak aydınlatılamamıştır. Bu çalışma FMS hastalarında endocan, ET-1, IL-1, IL-6, IL-8, MCP-1, TNF-a ve VEGF-A düzeylerinin ağrı/nöropatik ağrı ile ilişkisini belirlemek amacıyla planlandı.
Gereç ve Yöntem: Çalışmaya dâhil edilme kriterlerini karşılayan 44 FMS hastası ve yaşları eşleştirilmiş 44 premenopozal sağlıklı kontrol alındı. Fibromiyalji grubu Visual Analog Ölçeği, Beck Depresyon Ölçeği, Beck Anksiyete Ölçeği, Fibromiyalji Etki Anketi ve LANSS Ağrı Ölçeği açısından değerlendirildi. Serum endokan, ET-1, IL-1, IL-6, IL-8, MCP-1, TNF-α ve VEGF-A değerleri ELISA yöntemi ile belirlendi. Protein-protein etkileşimi, moleküler docking analizi ile değerlendirildi. Biyoinformatik analiz, STRING v 11.5 protein aracı kullanılarak yapıldı.
Bulgular: Endocan, ET-1, IL-1, IL-6, IL-8, MCP-1, TNF-α ve VEGF-A FMS hastalarında kontrol grubuna göre anlamlı olarak yüksekti. 44 hastanın 24'ünde nöropatik ağrı vardı. Ağrı/nöropatik ağrı ile serum belirteçleri arasında korelasyon saptanamadı. Proteinlerin yüksek etkileşim ve homoloji skorları tanımlandı.
Sonuç: Bu belirteçlerin ağrı/nöropatik ağrı ilişkisi belirlenememiştir ancak proteinlerin hesaplanan bağlanma enerjileri ve aktiviteleri ilerideki çalışmalar için önemli ipuçları sağlamıştır.
