Clinical efficacy of mychophenolate mofetil in treating lichen planopilaris

Lichen planopilaris (LPP) is a chronic inflammatory disorder of hair without a proven effective and safe treatment. To objectively assess the clinical efficacy of mycophenolate mofetil (MMF) in patients suffering from LPP, a retrospective cohort study was conducted on 52 patients who treated with MMF (2 g/day) at least for 6 months. LPP activity index (LPPAI) before and after treatment was calculated and compared. Most of the patients were female and belonged to the age group of 50-60 years. All of the disease activity indices were significantly improved after 6 months of therapy (p < 0.001). The majority of patients had LPPAI 4-6 and 0-2, before and after treatment, respectively. After 6 months of treatment, half of patients showed a disease activity decrease (LPPAI reduced >25% compared to the baseline value). Systemic MMF is an effective and relatively safe treatment modality for patients with LPP and could lead to significant reduction in disease activity regarding both subjective and objective indices.
