Lichen planopilaris (LPP) is a chronic inflammatory disorder that causes permanent scalp hair loss and significant patient discomfort.
We 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.
We 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.
Patients 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.
Retrospective analysis and small sample size were limitations.
MMF 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.
扁平苔藓性脱发(LPP)是一种慢性炎症性疾病,会导致头皮永久性脱发,给患者带来严重不适。
我们旨在评估霉酚酸酯(MMF)治疗既往外用、皮损内或口服抗炎药物(如羟氯喹或环孢素)治疗失败的 LPP 患者的疗效和安全性。
我们对 2003 年至 2007 年在一家单中心进行的开放性、非对照研究中,16 例接受至少 6 个月 MMF 治疗的 LPP 成年患者进行了回顾性图表分析。采用 LPP 活动指数(LPPAI)对主观和客观终点进行量化,并采用配对 t 检验评估治疗前后的评分。监测不良事件。
尽管既往接受了多种治疗,但接受 MMF 治疗的患者的活动性 LPP 体征和症状明显减轻(P<0.005)。12 例患者中,5 例为完全缓解者(LPPAI 评分下降>85%),5 例为部分缓解者(LPPAI 评分下降 25%-85%),2 例为治疗失败者(LPPAI 评分下降<25%)。4 例患者因不良事件退出试验。
回顾性分析和样本量小是本研究的局限性。
在至少 6 个月的治疗后,MMF 治疗既往多种治疗失败的 12 例患者中的 10 例(83%)有效减轻了活动性 LPP 的体征和症状。
