Abstract:
ObjectiveTo investigate the correlation of the serum and synovial fluid interleukin (IL)-1β,IL-6,tumor necrosis factor(TNF)-α and bone marrow edema with osteoarthritis of the knee (KOA).MethodsThe clinical data of 331 KOA patients were included and all patients had knee MRI.Bone marrow edema were detected in 172 cases and 159 cases had non-bone marrow edema.The clinical symptoms,WOMAC score,and the serum and synovial fluid IL-1β,IL-6,TNF-α levels were compared using One-way ANOVA analysis and Spearman's correlation analysis.Results① The serum and synovial fluid IL-1β,IL-6,TNF-α in osteoarthritis was positively correlated(serum r=0.24,0.38,0.31; synovial fluid r=0.20,0.29,0.33 ; all P＜0.05) ; ② The serum and synovial fluid IL-6 and TNF-α levels of osteoarthritis with bone marrow edema were significantly higher than those of the osteoarthritis without bone marrow edema(serum F=8.139,7.172; synovial fluid F=9.201,7.001; all P＜0.05); ③ The serum and synovial fluid TNF-α,IL-6 levels was associated with osteoarthritis with bone marrow edema in volume (serum r,=0.27,0.26; synovial fluid rs=0.29,0.32; all P＜0.05) and severity(serum rs=0.29,0.27; synovial fluid rs=0.29,0.31; all P＜0.05); ④ The serum and synovial fluid IL-1β,IL-6,TNF-α of osteoarthritis with synovitis was significantly higher than that of osteoarthritis without synovitis group (group of bone edema:serum F=3.931,5.866,5.514; synovial fluid F=4.211,5.202,5.972; all P＜0.05.non-bone edema patients:serum F=3.513,3.114,7.112; synovial fluid F=3.722,3.965,8.891; all P＜0.05).ConclusionIL-1β,IL-6,TNF-α are elevated in osteoarthritis with synov-itis.IL-6 and TNF-α are elevated significantly in knee osteoarthritis with bone marrow edema in particular.
