Linear IgA Bullous Dermatosis: A Retrospective Study of 23 Patients in Denmark
Kristina Lings, Anette Bygum
Linear IgA bullous dermatosis (LAD) is an autoimmune, chronic bullous disease affecting primarily young children and adults. Studies on LAD are relatively sparse and from Scandinavia we could only find a few case reports. Therefore we decided to conduct a retrospective investigation of patients seen at our department since 1972. A total of 23 patients were identified; 7 children (F:M ratio 0.75) and 16 adults (F:M ratio 0.78). Mean age at disease onset in the two age groups were 2.7 and 56.8 years. Estimated incidence rate in our region: 0.67 per million per year. The most commonly used treatment modalities were corticosteroids, dapsone and sulphapyridine.
