Is nonalcoholic fatty liver disease independently associated with an increased incidence of cardiovascular disease in adult patients with type 1 diabetes? Context: Recent studies suggested that nonalcoholic fatty liver disease (NAFLD) is associated with an increased prevalence of cardiovascular disease (CVD) in type 1 diabetes. We assessed whether NAFLD also predicts the risk of incident CVD events in type 1 diabetic adults. We studied a retrospective cohort of 286 type 1 diabetic outpatients (mean age 43±14years; median duration of diabetes 17 [10-30] years) without secondary causes of chronic liver diseases, who were followed for a mean period of 5.3years for the occurrence of incident CVD events (a combined endpoint inclusive of nonfatal ischemic heart disease, nonfatal ischemic stroke or coronary/peripheral artery revascularizations). NAFLD was diagnosed by ultrasonography. Overall, 150 patients (52.4%) had NAFLD at baseline. During a mean follow-up of 5.3±2.1years, 28 patients developed incident CVD events. Patients with NAFLD had a higher incidence of CVD events than those without NAFLD (17.3% vs. 1.5%, p<0.001). NAFLD was associated with an increased risk of CVD events (hazard ratio [HR] 8.16, 95% confidence interval [CI] 1.9-35.1, p<0.005). Adjustments for age, sex, body mass index, smoking, diabetes duration, hemoglobin A1c, dyslipidemia, hypertension, chronic kidney disease, prior ischemic heart disease and serum gamma-glutamyltransferase levels did not appreciably attenuate the association between NAFLD and incident CVD (adjusted-HR 6.73, 95% CI 1.2-38.1, p=0.031).

This is the first observational study to demonstrate that NAFLD is associated with an increased risk of incident CVD events in type 1 diabetic adults, independently of established CVD risk factors and diabetes-related variables. Final Decision: yes
