Methylprednisolone combined with mycophenolate mofetil for the treatment of oral mucosal pemphigoid: a case report and literature review
Abstract
Objective To investigate the application of mycophenolate mofetil (MMF) in oral mucosal pemphigoid and provide a clinical reference. Methods One case of glucocorticoids combined with MMF in the treatment of oral mucosal pemphigoid was reported, and the clinical application of MMF in oral mucosa-related bullous diseases was discussed. Results One patient with a clinical diagnosis of “oral mucosal pemphigoid” was treated with methylprednisolone (36 mg, qd, morning dose) or combined hydroxychloroquine sulfate (0.1 g/time, bid) and thalidomide capsules (50 mg, qd, bedtime) and other drugs. The patient’s disease was slowly controlled but prone to recurrence. The treatment regimen was immediately adjusted, i.e., methylprednisolone (36 mg, qd, morning dose) was combined with MMF (0.5 g/time, bid) for 2 weeks, which resulted in ideal lesion healing control. After 8 weeks of methylprednisolone combined with MMF, the dose of methylprednisolone was gradually reduced to 12 mg, qd, and MMF was reduced to 0.5 g, qd, the patient’s symptoms improved significantly, and no obvious lesions were found in the mouth. The dose was then reduced and maintained according to the principle of pemphigoid treatment. Methylprednisolone (8 mg, qd, morning dose) and MMF (0.5 g, qd) have been used for 6 months of maintenance treatment, and they are still being followed up. As yet, the patient’s condition is stable without obvious lesions and new blisters, and no obvious side effects have been observed. A review of the literature shows that MMF is widely used in the field of dermatology to treat a variety of immune diseases, such as connective tissue diseases and autoimmune blistering diseases. According to the reports of adverse reactions to MMF, digestive system reactions are the most common adverse reactions; therefore, patients with active gastrointestinal diseases should be treated with caution, followed by bone marrow suppression, and it is recommended to monitor liver function and blood routine in patients using MMF. The safety and efficacy of MMF for treating pemphigoid involving the skin have been reported in the literature, but oral mucosal doctors still lack experience for treating mucous membrane pemphigoid. Conclusions As a new immunosuppressant, MMF has high safety and no obvious side effects and can be considered as a combination adjuvant drug for patients with severe clinical disease and refractory oral mucosal pemphigoid.
