Varpuluoma O, et al. - Authors studied the association between diabetes medications other than dipeptidyl peptidase-4 inhibitors (DPP-4i) and development of bullous pemphigoid (BP). By analyzing national Finnish registry data for 3,397 BP patients and 12,941 basal cell carcinoma patients as controls, they assessed the prevalence of diabetes among BP patients and the relationship between the use of diabetes drugs (excluding DPP-4i, metformin and insulin) and BP. Findings did not suggest any association of the investigated diabetes drugs with increased risk of BP in a Finnish patient-base, thereby suggesting safe use of these medicines in this population.
