Abstract

Background: There is currently limited population-based data on the effect of type 2 diabetes mellitus (T2DM) on bullous pemphigoid (BP) inpatients. Aims: To evaluate the relative comorbidities, medical complications, and mortality rates between BP inpatients with and without T2DM. Methods: All inpatients with a primary BP diagnosis in the National Inpatient Sample from 2003 to 2012 were queried. BP inpatients with or without T2DM were compared to identify disparities in relative comorbidities and medical complications. Comorbidities were established using the Agency for Healthcare Research and Quality standardized values. Medical complications were classified using ICD-9 codes. Results: Of the 1978 BP patients identified, 660 (33.4%) had a concurrent diagnosis of T2DM. These patients had significantly higher rates of concurrent comorbidities, including chronic renal failure, congestive heart failure, iron deficiency anemia, hypertension, obesity, and peripheral vascular disease. On bivariate analysis, T2DM patients also had significantly higher rates of medical complications including acute kidney injury (14.5% vs. 10.1%, p = 0.004) and venous thromboembolism (1.8% vs. 0.5%, p = 0.012). On multivariable-adjusted analysis, the odds of venous thromboembolism (OR = 3.01, p = 0.027) remained increased. Inpatient mortality did not differ between the groups. Conclusions: Our findings suggest that BP inpatients with T2DM have a greater medical comorbidity and complication burden. However, inpatient mortality was not increased.
