Abstract
BACKGROUND: Latent Autoimmune Diabetes in Adults (LADA) is the second most common form of diabetes, but data on its clinical course and prognosis are scarce. We compared long-term risk of mortality and cardiovascular outcomes in patients with LADA, type 2 diabetes mellitus (T2D), and insulin deficient diabetes (IDD). METHODS: We conducted a cohort study of 4368 adults with diabetes referred to the Department of Endocrinology, Odense University Hospital, Denmark, between 1997 and 2012. Data on comorbidity, cardiovascular outcomes and death were obtained from prospective medical databases. We compared adjusted hazard ratios (HRs) of mortality and cardiovascular outcomes for patients with LADA, T2D and IDD, respectively. RESULTS: We included 327 patients with LADA, 3539 with T2D and 502 with IDD. At diagnosis, patients with LADA were older (50 years (IQR 37-59)) than IDD patients (40 years (IQR 28-52)), but younger than patients with T2D (55 years (IQR 45-64)). During a median follow-up period of 6.6 years (IQR 3.4-9.4), patients with IDD had higher mortality than patients with LADA, age- and gender-adjusted HR 2.2 (95% CI, 1.5-3.2). T2D also conferred higher mortality than LADA, HR 1.4 (95% CI, 1.0-1.9). Compared with LADA patients, cardiovascular outcome rates were increased both with IDD, HR 1.2 (95% CI, 0.7-2.0) and T2D, HR 1.2 (95% CI, 0.8-1.8), with the strongest association observed for T2D vs. LADA and acute myocardial infarction HR 1.7 (95% CI, 0.8-3.5). CONCLUSION: LADA seems to be associated with lower mortality and lower risk of cardiovascular events, compared with both T2D and IDD.
