Methods SF was collected from the knees of 45 OA 22 RA patients and 20 asymptomatic organ donors. Eight biomarkers were selected and analyzed by using an enzyme-linked immunosorbent assay interleukin IL -1 IL-6 IL-8 and IL-11 leukemia-inhibitory factor LIF cartilage oligomeric protein COMP osteocalcin and osteogenic protein 1 OP-1 . Data are expressed as medians interquartile ranges . The effects of sex and disease activity were assessed on the basis of the Western Ontario and McMaster Universities index score for patients with OA and on the basis of white blood cell count erythrocyte sedimentation rate and C-reactive protein level for patients with RA. Results The mean ages SD of the patients were as follows 53 9 years for patients with OA 54 11 years for patients with RA and 52 7 years for asymptomatic organ donors. No effect of participants sex was identified. In the SF of patients with RA four of five cytokines were higher than those in the SF of patients with OA and those of asymptomatic organ donors. The most significant differences were found for IL-6 and IL-8 where IL-6 concentration in SF of patients with RA was almost threefold higher than that in patients with OA and fourfold higher than that in asymptomatic donor controls pg ml 1 vs. pg ml vs. pg ml P and P respectively . IL-8 .
