Multiple courses of steroid pulse therapy are required in treating acquired idiopathic generalized anhidrosis patients with a large anhidrotic area: A retrospective study of 28 cases.

Abstract

Patients with acquired idiopathic generalized anhidrosis (AIGA) demonstrate a sudden loss of sweating function without neurological or endocrine abnormalities. The main treatment is steroid pulse therapy. However, the number of courses required for improvement has been unclear. This study aims to clarify the factors associated with AIGA disease severity and with AIGA patients' responses to steroid pulse therapy. We retrospectively analysed the clinical information of 28 patients with AIGA in our department from the last 10 years. Univariate analysis revealed that patients with a large anhidrotic area need multiple courses of steroid pulse therapy.
