Abstract [en]

Focal hyperhidrosis is a condition that may disturb emotional, social and professional life. Treatment options for severe cases are surgical sympathectomy and local chemical sweat gland denervation by intradermal injections of botulinum toxin A (Btx A). The Dermatology Life Quality Index (DLQI) is a simple validated questionnaire designed to measure and compare disability in different skin diseases. The aim of this study was to assess quality of life with the DLQI before and after treatment with botulinum toxin injections in a group of patients with severe hyperhidrosis. DLQI was administered to 58 randomly chosen patients before and after treatment. All patients answered the DLQI questionnaire prior to treatment and 53/58 at mean 5.2 months after treatment. The mean DLQI score in the 58 patients before treatment was 10.3 (2-23). In the group of 16/53 patients who had a relapse of sweating when answering the DLQI a second time, no significant improvement was seen [score 10.6 before and 8.8 after treatment (P = 0.21)]. In patients without relapse, a 76% improvement was obtained (DLQI was reduced from 9.9 to 2.4; P < 0.0001). The study showed that focal hyperhidrosis may considerably reduce life quality and the disability experienced by the patients can be largely reversed by botulinum toxin injections.
