Oral ulcers produced by mycophenolate mofetil in two liver transplant patients

Area of Science:

• Transplant Medicine
• Immunosuppression Therapy
• Oral Pathology

Background:

• Oral ulcers are common in transplant recipients, often linked to immunosuppressive therapy.
• Infectious causes and adverse drug reactions are key considerations for oral ulceration in this population.
• Mycophenolate mofetil (MMF) is a widely used immunosuppressant in combination with calcineurin inhibitors and steroids.

Observation:

• Two liver transplant patients developed oral ulcers.
• These ulcers appeared during immunosuppressive therapy involving MMF.
• The oral ulcers resolved rapidly after discontinuing MMF.

Findings:

• Mycophenolate mofetil (MMF) can be associated with the development of oral ulcers in liver transplant patients.
• Cessation of MMF led to prompt resolution of oral ulcer symptoms.
• This represents a unique presentation of MMF-induced oral complications in liver transplant recipients.

Implications:

• Clinicians should consider MMF as a potential etiology for oral ulcers in liver transplant patients.
• Early recognition and drug withdrawal may effectively manage MMF-related oral ulcerations.
• Further investigation into the mechanisms of MMF-induced oral toxicity is warranted.
