Background Adipocytokines are soluble mediators secreted by adipose tissue and immune cells with potent immune regulatory functions. Some adipocytokines have been previously associated with disease activity and radiographic progression in patients with rheumatoid arthritis (RA)1.

Objectives To investigate associations between adipocytokines, clinical and traditional laboratory markers as well as with ultrasound synovitis in patients with RA.

Methods A total of 82 patients with RA (62 females, median disease duration 4.2 years) were enrolled into this study. All patients underwent clinical examination (swollen joint count - SJC, tender joint count – TJC, Disease activity score - DAS28-ESR and DAS28-CRP, Clinical disease activity index - CDAI, Simplified disease activity index - SDAI). Moreover, ultrasound examination of 7 selected joints mostly affected in RA (wrist, second and third metacarpophalangeal and proximal interphalangeal, and second and fifth metatarsophalangeal joints) was performed to measure synovial hypertrophy in Grey Scale (GS) and pathological neovascularization in Power Doppler (PD) using semi-quantitative grading 0–33. Blood samples were taken at the same day as clinical and ultrasound assessments. Serum concentrations of adiponectin, resistin, visfatin, leptin and CRP were measured. Clinical and laboratory measures were correlated with ultrasound findings using Spearman's correlation coefficient.

Results Serum visfatin and resistin levels were associated with the disease activity (Figure 1) and correlated significantly with DAS28-ESR (r=0.473, p<0.001; r=0.363, p<0.001, resp.), DAS28-CRP (r=0.443, p<0.001; r=0.348, p<0.005, resp.), SDAI (r=0.431, p<0.001; r=0.344, p<0.005, resp.), CDAI (r=0.419, p<0.001, r=0.344, p<0.005, resp.) and with CRP levels (r=0.456, p<0.001; r=0.364, p<0.001, resp.). Moreover, visfatin and resistin levels significantly correlated with GS (r=0.430, p<0.001, r=0.273, p<0.05, resp.) and PD synovitis scores (r=0.309, p<0.01, r=0.283, p=0.01, resp.). Neither leptin nor adiponectin correlated with parameters of disease activity in patients with RA.

Conclusions Our study supports circulating visfatin and resistin as promising serum pro-inflammatory biomarkers reflecting clinical, laboratory as well as ultrasound parameters of synovial inflammation in RA.
