Evaluation of Demodex mite in chronic urticaria

Abstract

Objective: Determining the possible role of Demodex mites in patients with chronic urticaria Methods: Demodex screening results in 49 patients with chronic urticaria were evaluated retrospectively. Results: The mean number of Demodex mites per 1 cm2 measured with standardized skin-surface biopsy (SSSB) was 0.89 which was at a similar level as control groups in the literature. Conclusion: Demodex mites seemed not to play a role in patients with chronic urticaria who had no facial eruptions. Patients with skin eruptions with the possible contribution of Demodex as rosacea could be investigated for chronic urticaria in other studies.
