Abstract

Purpose. The aim of this study was to investigate the association between prostanoid [thromboxane (TxA2) and prostacyclin (PGI2)] levels in synovial fluid and infrapatellar fat pad (IPFP)/ suprapatellar fat pad (SPFP) thickness as well as other clinical findings in knee steoarthritis (OA) patients. Materials and Methods: 16 patients with knee OA with effusion were included. The average pain levels were evaluated using a Visual Analogue Scale (VAS). The pain, stiffness, and physical functions were evaluated using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). The levels of 6-keto-PGF1α, stable metabolite of PGI2, and TxB2, stable metabolite of TxA2, were measured in synovial fluid using an enzyme immunoassay. Results: 6-keto-PGF1α levels were significantly greater than TxB2 levels in synovial fluid of patients with OA. TxB2 levels and TxB2/6-keto- PGF1α ratio were negatively correlated with SPFP and cartilage thickness, respectively. IPFP thickness was positively correlated with SPFP thickness and effusion volume. WOMAC scores were positively correlated with VAS-activity and VAC-evening scores. Conclusion: In comparison to 6-keto- PGF1α levels in synovial fluid, TxB2 levels seem to be more associated with ultrasonographic findings in patients with OA.

Özet

Amaç: Bu çalışmada, diz osteoartriti olan hastaların sinoviyal sıvılarındaki prostanoidlerin [tromboksan (TxA2) ve prostasiklin (PGI2)] düzeyi ile infrapatellar ve suprapatellar yağ yastığı kalınlığı ve diğer klinik parametreler arasındaki ilişkinin değerlendirilmesi amaçlanmıştır. Gereç ve Yöntem: Çalışmaya efüzyonlu diz osteoartriti bulunan 16 hasta dahil edilmiştir. Ağrı düzeyleri görsel analog skala (VAS) ile değerlendirilmiştir. Ağrı, sertlik ve fiziksel fonksiyon osteoartrit indeksi (WOMAC: Western Ontario and McMaster Universities Osteoarthritis Index) ile değerlendirilmiştir. PGI2’nin kararlı metaboliti olan 6-keto-PGF1α ve TxA2’nin kararlı metaboliti olan TxB2 düzeyleri enzim immunoassay yöntemi ile ölçülmüştür. Bulgular: Sinoviyal sıvıda ölçülen 6-keto-PGF1α düzeyleri TxB2 düzeylerine göre anlamlı derecede yüksek bulunmuştur. TxB2 düzeyleri ile suprapatellar yağ yastığı kalınlığı ve TxB2/6-keto- PGF1α oranı ile kıkırdak kalınlığı arasında negatif korelasyon bulunmaktadır. Infrapatellar yağ yastığı kalınlığı ile suprapatellar yağ yastığı kalınlığı ve efüzyon hacmi arasında pozitif korelasyon bulunmaktadır. WOMAC değerleri ile VAS-aktivite ve VAS-gece skorları arasında pozitif korelasyon bulunmaktadır. Sonuç: 6-keto-PGF1α düzeylerine kıyasla, sinoviyal sıvı TxB2 düzeyleri osteoartritli hastalardaki ultrasonografik bulgular ile daha çok ilişkili bulunmuştur.
