OBJECTIVE: Sedentary lifestyle and a western diet promote subacute-chronic inflammation, obesity, and subsequently dysglycemia. The aim of the current study was to evaluate the efficacy of the anti-inflammatory drug salsalate to improve glycemia by reducing systemic inflammation in obese adults at risk for the development of type 2 diabetes.
RESEARCH DESIGN AND METHODS: In a double-masked, placebo controlled trial, we evaluated 20 obese nondiabetic adults at baseline and after 1 month of salsalate or placebo.
RESULTS: Compared with placebo, salsalate reduced fasting glucose 13% (P < 0.002), glycemic response after an oral glucose challenge 20% (P < 0.004), and glycated albumin 17% (P < 0.0003). Although insulin levels were unchanged, fasting and oral glucose tolerance test C-peptide levels decreased in the salsalate-treated subjects compared with placebo (P < 0.03), consistent with improved insulin sensitivity and a known effect of salicylates to inhibit insulin clearance. Adiponectin increased 57% after salsalate compared with placebo (P < 0.003). Additionally, within the group of salsalate-treated subjects, circulating levels of C-reactive protein were reduced by 34% (P < 0.05).
CONCLUSIONS: This proof-of-principle study demonstrates that salsalate reduces glycemia and may improve inflammatory cardiovascular risk indexes in overweight individuals. These data support the hypothesis that subacute-chronic inflammation contributes to the pathogenesis of obesity-related dysglycemia and that targeting inflammation may provide a therapeutic route for diabetes prevention.
