Effect of puberty, menstruation, pregnancy, lactation, and menopause on chronic urticaria activity

Abstract

Background: Chronic urticaria (CU) is a systemic disorder which is characterized by recurrent wheals and/or angioedema lasting more than 6 weeks. Sex hormones have been suggested to play a role in CU pathogenesis, however, their clinical implications have not been adequately described in the literature. Objective: To determine whether conditions that change sex hormone levels such as puberty, menstruation, pregnancy, breastfeeding, and menopause affect the course of CU. Methods: This cross-sectional questionnaire study was conducted on female CU patients at Okmeydani Training and Research Hospital UCARE Center between 2016 and 2017. The open-ended questionnaire consisted of questions evaluating the effects of hormonal changes on disease course. Results: A total of 111 female CU patients were included in the analysis. During the perimenstrual period, CU symptoms worsened in 29% of patients but improved in 4.8%. The disease course did not change in the majority of patients during puberty, pregnancy, lactation, or menopause (100%, 96%, 83.8%, and 95.6%, respectively). Conclusions: Contrary to expectations, a change in sex hormone levels had no effect on the course of CU in the majority of cases. However, disease activity increased in one-third of CU patients during the perimenstrual period.
