Abstract

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.

Association between synovial fluid prostanoid levels and ultrasonographic findings in knee osteoarthritis

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.
