Introduction
Bullous pemphigoid (BP) is the most common autoimmune blistering disease. Although pruritus is a leading symptom in BP, its specific characteristics have not been explored.

Aim
To determine the itch characteristics in newly diagnosed BP patients by using the Questionnaire of Descriptive Assessment of Pruritus and visual analogue scale (VAS) and to correlate itch with disease severity.

Material and methods
The study included 32 patients with BP (mean age: 75.4 ±12.2 years; 20 women, 12 men), who filled in the questionnaire. Bullous Pemphigoid Disease Area Index (BPDAI) was assessed.

Results
In 78.1% of BP patients pruritus occurred at least once daily. Pruritus was most frequent in the evening and at night and frequently persisted for more than 10 min in more than a half of patients (long itch episodes). Aggravating factors were sweating (50.0%), heat (59.4%) and stress (46.9%), but the major relieving factor was cold (34.4%). Itch intensity in BP was assessed as moderate (mean VAS score: 5.8 points) and did not correlate with disease severity (BPDAI). BP patients declared difficulties caused by pruritus: falling asleep (53.1%) and awakening at night (50%).

Conclusions
This study provided detailed characteristics in BP patients confirming that pruritus is classified as an important troublesome symptom. Therefore there is a need to search for therapeutic solutions.
