Research Article: Impact of COVID- Vaccine and COVID- Infection on Vitiligo Activity and Progression
Abstract:
Coronavirus disease (COVID-), caused by severe acute respiratory syndrome coronavirus (SARS-CoV-), has been causing a worldwide pandemic since . The clinical manifestations of COVID- infection are complex and diverse, and the whole systems may be affected, including the skin. Vitiligo is an acquired chronic depigmenting disorder of the skin resulting from selective destruction of melanocytes, and autoimmune abnormality is one of the main causes of vitiligo. Until now, there have been some case reports of new vitiligo or deterioration of original vitiligo after COVID- vaccination and infection, but large scale epidemiological data are lacking. In a recent study, the author reported active vitiligo vulgaris following the administration of the Oxford–AstraZeneca (AZD) vaccine against SARS-CoV-. They believe that immune activation during SARS-CoV- infection may increase vitiligo disease activity. In another study, cases (.%) had new-onset or worsening vitiligo after COVID- vaccination and two cases (.%) developed vitiligo following primary COVID- infection. Patients who have comorbid autoimmune diseases were more likely to develop vitiligo.
