Amylin in the insulin resistance of patients with rheumatoid arthritis

Abstract: Objectives: Amylin, which is co-secreted with insulin, plays a role in glycemic regulation and is impaired in type 2 diabetes. In the present study we assess, for the first time, the implication of amylin in the development of insulin resistance (IR) in rheumatoid arthritis (RA). Methods: This was a cross-sectional study involving 361 non-diabetic individuals, 151 patients with RA and 210 sex-matched controls. Insulin, C-peptide, amylin, lipoprotein serum concentrations, and IR indexes by homeostatic model assessment (HOMA2) were evaluated in patients and controls. A multivariable analysis, adjusted for IR-related factors, was performed to determine the differences between patients and controls vis-à-vis amylin and how it is related to IR in RA. Results: Insulin, C-peptide and HOMA2-IR indexes were higher in RA patients than in controls. Amylin serum levels were found to be upregulated in RA patients compared to controls (1.36 ± 0.81 vs. 1.79 ± 1.51 ng/ml, p=0.011), although this difference was lost after adjusting for covariates (p=0.46). While amylin positively correlated with the presence of rheumatoid factor (beta coef. 0.90 [95%CI -0.23-1.56], p=0.009) and SDAI (beta coef 0.01 [95%CI 0.00-0.03], p=0.034), no significant association with other disease activity scores, glucocorticoid intake, methotrexate use or TNF-alpha inhibitors was found. Conclusions: IR in RA does not appear to be mediated by amylin. This would imply that the mechanisms associated with IR in RA patients differ from those at work in type 2 diabetes.
