Correlation of IL-17 Level in Synovia and Severity of Knee Osteoarthritis
نویسندگان
چکیده
BACKGROUND The aim of this study was to evaluate the role of interleukin-17 (IL-17) level in synovia and its relationship with the severity of knee osteoarthritis (OA). MATERIAL AND METHODS We enrolled 226 OA patients and 106 controls in this study. The symptomatic/radiation severity of OA was assessed by the Western Ontario McMaster University Osteoarthritis Index (WOMAC) pain score/Kellgren-Lawrence (KL) grading system. Serum IL-17 levels were measured by enzyme-linked immunosorbent assay (ELISA). RESULTS Synovia IL-17 levels were significantly higher in OA patients compared with controls (P<0.01), and were negatively correlated with OA severity. IL-17 level gradually decreased among different phases but lacked statistical significance. CONCLUSIONS IL-17 might play a crucial role in the pathogenesis of OA and is closely related to pain. Blocking the IL-17 signaling pathway may delay pain related to OA.

ABSTRACT Background and Objectives: Osteoarthritis (OS) is the most common type of arthritis and joint disease, especially in women. Proinflammatory cytokines, biochemical factors, specially matrix metalloproteinases, and reactive oxygen species play important roles in joint destruction in this disease. Therefore, the present study aimed to evaluate ...
متن کاملCorrelation between systemic markers of inflammation and local synovitis in knee osteoarthritis
Background: In the elderly population joint swelling, effusion and pain indicate local synovitis and the presence of inflammation. At present, no serum marker has been shown linking to knee synovitis in KOA. With regard to serum high sensitive C-reactive protein (hsCRP) as a measure of inflammation, this study aimed to determine the association of systemic inflammation with local synovitis, as ...
متن کاملSoluble Mediators in Posttraumatic Wrist and Primary Knee Osteoarthritis
Background: New discoveries about the pathophysiology changed the concept that all forms of osteoarthritis are alike; this lead to the delineation of different phenotypes such as age, trauma or obese related forms. We aim to compare soluble mediator profiles in primary knee and posttraumatic wrist osteoarthritis. Based on the general faster progression rate of wrist osteoarthritis, we hypothes...
