AIM: To estimate the frequency of obesity in a Russian cohort of patients with early rheumatoid arthritis (RA), determine adipocytokine (adiponectin, leptin) levels and their relation to RA activity. MATERIALS AND METHODS: 47 patients with early RA fulfilling ACR/EULAR(2010) criteria and using no BAID or GC. Mean age 57 [47;62] yr, duration of disease 7 [4;8] yr, median of DAS28 5.9 [5.3; 69]. Control group included 30 age-matched healthy donors. The degree of obesity was assessedfrom metabolic syndrome criteria (NCEP/ATPIII, RSSC, WHO); leptin and adiponectin were measured by ELISA, the L/A ratio was calculated. RESULTS: Patients with RA had the same mean BMI but greater waist circumference (WC) and waist/hip ratio than controls (p=0.003 and p = 0.04). Obesity was diagnosed in 63.8 and 40% of the patients in these groups (p=0.04) based on NCEP/ ATPIII criteria and in 65.9 and 40% respectively by WHO criteria. The occurrence of obesity by RSSC criteria was not significantly different (p = 0.9). In patients with RA adiponectin level was higher (p=0.04) while leptin level and L/A ratio lower (p=0.02 and 0.003) than in controls. BMI correlated with ESR, CRB, DAS28, leptin and L/A (p<0.05) in both groups. ESR positively correlated with leptin level andA/L but negatively with adiponectin level (p<0.05). CONCLUSION: The study showed high prevalence ofobesity in patients with early RA and its relation to inflammation. It was associated with increased serum adiponectin level, decreased leptin level and insulin resistance.
