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.
