Several studies have recently reported the usage of methotrexate (MTX) in AA; however, the pure effect of MTX monotherapy remains elusive.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>To evaluate efficacy and safety of oral methotrexate monotherapy for AA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We retrospectively reviewed the clinical course of AA patients including pediatric cases treated with MTX monotherapy. Their detailed clinical data including original severity of AA, final treatment outcome, the duration until the maximum response, and side effects, were assessed. Statistical analysis was performed to evaluate if the clinical factors including the duration of current alopecia, age, the presence of body hair loss, and sex were associated with treatment response.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>All included patients had severe AA and failed standard therapies. Thirteen out of 15 cases demonstrated improvement during the monotherapy, and all responders demonstrated the maximum response within 1 year. Female patients had significantly better outcomes than male patients. Other factors did not significantly influence on the treatment outcome. None of the patients experienced side effects that were severe enough to terminate the treatment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
