Aims To explore insulin sensitivity and insulin secretion in people with latent autoimmune diabetes in adulthood ( LADA ) compared with that in people with Type 2 diabetes. Methods A total of 12 people with LADA , defined as glutamic acid decarboxylase ( GAD ) antibody positivity and > 1 year of insulin independency (group A) were age‐matched pairwise to people with Type 2 diabetes (group B) and to six people with Type 2 diabetes of similar age and BMI (group C). β‐cell function (first‐phase insulin secretion and assessment of insulin pulsatility), insulin sensitivity (hyperinsulinemic‐euglycemic clamp) and metabolic response during a mixed meal were studied. Results Both first‐phase insulin secretion and insulin release during the meal were greater ( P = 0.05 and P = 0.009, respectively) in Type 2 diabetes as compared with LADA ; these differences were lost on adjustment for BMI (group C) and could be explained by BMI alone in a multivariate analysis. Neither insulin pulsatility, incretin secretion nor insulin sensitivity differed among the groups. Conclusions We found no evidence that LADA and Type 2 diabetes were distinct disease entities beyond the differences explained by BMI .
