Abstract
Background
The incidence of bullous pemphigoid (BP) is increasing in Finland.
Objectives
To investigate the clinical presentation, comorbidities, and medications in a cohort of Finnish patients with confirmed BP managed in a university hospital setting.
Materials & Methods
An observational retrospective study of all consecutive patients diagnosed with BP in 2012-2013 at the Department of dermatology, HUCH. The prevalence of the most common comorbidities was compared to that in a sample population aged over 30 years.
Results
Seventy patients were included (mean age: 77 years at diagnosis). The most common comorbidities were hypertension (44%), type 2 diabetes (34%), and ischaemic heart disease (26%). Almost half of the cohort had a neurological condition (46%). A statistically significant association was identified between BP and a past history of malignancies (17%; p<0.001), type 2 diabetes (24%; p<0.001), and chronic obstructive lung disorder (COPD) (10%; p=0.004), compared to an age-matched control group. The most common standard drugs were statins, beta-blockers, and diuretics. In total, 83% of the patients with type 2 diabetes took anti-diabetic treatments, mainly metformin (80%) and gliptins (55%).
Conclusions
Significant associations were identified between BP and COPD, type 2 diabetes, and a past history of malignancy, compared to the general population. In this study, the specific role of some medications, such as gliptins, may account for the onset of BP in diabetic type 2 patients.
