Efficacy and safety of mycophenolate mofetil for lichen planopilaris

BackgroundLichen planopilaris (LPP) is a chronic inflammatory disorder that causes permanent scalp hair loss and significant patient discomfort.ObjectivesWe sought to determine the efficacy and safety of mycophenolate mofetil (MMF) for treatment of LPP in patients who had failed prior topical, intralesional, or oral anti-inflammatory medications such as hydroxychloroquine or cyclosporine.MethodsWe conducted a retrospective chart review of 16 adult patients with LPP treated with at least 6 months of MMF in an open-label, single-center study from 2003 to 2007. Subjective and objective end points were quantified using the LPP Activity Index (LPPAI) and scores before and after treatment were assessed using a paired t test. Adverse events were monitored.ResultsPatients who completed treatment with MMF had significantly decreased signs and symptoms of active LPP despite having failed multiple prior therapies (P < .005). Five of 12 patients were complete responders (LPPAI score decreased>85%), 5 of 12 patients were partial responders (LPPAI score decreased 25%-85%), and two of 12 patients were treatment failures (LPPAI score decreased<25%). Four patients withdrew from the trial because of adverse events.LimitationsRetrospective analysis and small sample size were limitations.ConclusionsMMF was effective at reducing the signs and symptoms of active LPP in 83% of patients (10 of 12) who had failed multiple prior treatments after at least 6 months of treatment.
