The retrospective study evaluating the outcomes of high-dose methylprednisolone pulse therapy for 483 moderate-to-severe alopecia areata patients

Alopecia areata (AA) is a chronic autoimmune skin disease with hair loss, which often results in a poor prognosis. Although the high-dose intravenous methylprednisolone pulse therapy (IVMP) is used for AA, predictive factors affecting efficacies of IVMP are not fully elucidated. Thus, we conducted a retrospective study reviewing IVMP for AA during January 2009 and December 2018. The study was approved by the ethical committee of the Tohoku University Graduate School of Medicine.
