Increased leptin levels in patients with rheumatoid arthritis: a meta-analysis.
Published data regarding the association of leptin levels with rheumatoid arthritis (RA) are contradictory. To derive a more precise estimation of this relationship, a meta-analysis was performed. ⋯ The present meta-analysis suggested that leptin levels were higher in RA patients than those in healthy controls, which may be subject to different region, race, age, BMI, disease duration and disease activity.
