Background: There are large discrepancies in reported mortality for bullous pemphigoid (BP). Objective: We sought to determine the mortality of a large cohort of patients with BP and compare this with age-matched control subjects. Methods: Data were collected on 223 patients with a new diagnosis of BP between 1998 and 2003 through our cutaneous immunofluorescence laboratory databases. The mortality of patients with BP was compared with that of age-matched control subjects in the general US population. Results: The 1-, 2-, and 5-year mortality was 0.23 (95% confidence interval = 0.18, 0.29), 0.37 (95% confidence interval = 0.31, 0.44), and 0.50 (95% confidence interval = 0.42, 0.57), respectively. However, relative to age-matched control subjects, no difference in expected mortality was detected. Limitations: This was a retrospective cohort analysis. Conclusions: Mortality of patients with BP is more likely related to advanced age and associated medical conditions than to disease-specific factors.
