Abstract

Introduction

Alopecia areata is an autoimmune disease of the hair follicle leading to non-scarring hair loss. Alopecia areata has a strong psychosocial impact. Rare associations with COVID-19 infection have been reported in the literature. Our objective  is to report a case series of alopecia areata associated with COVID-19  infection in Malagasy patients, seen in the department of Dermatology CHUJRB for the last two years.

Observation

Six female cases presented new-onset Alopecia areata. The mean age of patients was 36.83 years. No patients had a personal or family history of alopecia areata. They were all unvaccinated  against COVID-19. Two cases had  presented with the moderate form and 4 cases with the mild form. One case had received corticosteroid therapy for COVID-19. The mean  time between  the COVID-19  infection and the appearance of alopecia areata was 3 months. Five cases presented  with  different size and numbers of plaques. One case presented alopecia totalis. A biological inflammatory syndrome was found in two cases. All patients  received oral corticosteroids for alopecia with a good therapeutic response. Regrowth was marked in all cases after one month.

Conclusion

The occurrence of alopecia areata is one of the dermatological manifestations of COVID-19 infection. This fact could be explained by the dysimmunity phenonemon induced by COVID-19. The clinical and outcomes aspects as well as the good understanding of the physiopathological mechanism requires further studies.
