Background and AimsCurrently published data regarding the relationship between plasma/serum leptin levels and systemic lupus erythematosus (SLE) are contradictory. To derive a more precise evaluation of this relationship, a meta-analysis was performed.MethodsPublished literature from PubMed, Embase and Cochrane Library were obtained. The study quality was assessed by the Newcastle–Ottawa scale. Pooled standard mean difference (SMD) with 95% confidence interval (CI) was calculated by fixed-effects or random-effect model analysis. Heterogeneity among studies was estimated using the Cochran Q and I2 statistics.ResultsA total of 11 studies including 868 SLE patients and 591 controls were finally included in the meta-analysis. No significant differences in plasma/serum leptin levels was found between SLE patients and healthy controls when all studies were pooled into the meta-analysis (pooled SMD = 0.269, 95% CI = −0.188 to 0.726). However, subgroup analyses showed that SLE patients from an Asian population, age ≥40 years and BMI <25 had higher plasma/serum leptin levels when compared with controls.ConclusionThere is no significant difference in plasma/serum leptin levels between the entire group of SLE patients and controls. However, plasma/serum leptin levels are significantly higher in the subgroup of SLE patients from an Asian population ≥40 years of age and with a BMI <25.
