Kizilgul M, et al. - The prevalence of celiac disease (CD) among insulin-using type 2 diabetes patients with inappropriate glycemic control was investigated. Among patients with type 2 diabetes, with poor glycemic control despite insulin therapy, the prevalence of celiac disease was slightly higher than the actual CD prevalence in general population. In spite of insulin treatment, type 2 diabetic patients with inappropriate control of glycemia could be additionally tested for celiac disease, particularly if they had low C-peptide levels.
