Insights

This study details the first case of donor-derived Cryptococcus gattii meningoencephalitis after liver transplant. Early diagnosis and treatment with amphotericin B and fluconazole led to successful outcomes.

Area of Science:

  • Infectious Diseases
  • Transplantation Medicine
  • Mycology

Background:

  • Cryptococcal disease is a significant cause of morbidity and mortality in solid organ transplant recipients.
  • Donor-derived Cryptococcus spp. infections typically occur within the first month post-transplant.
  • Historically, C. neoformans complex has been the predominant cause, particularly in kidney and liver transplant recipients.

Purpose of the Study:

  • To report the first case of donor-derived Cryptococcus gattii complex meningoencephalitis in a liver transplant recipient.
  • To describe the successful treatment of this rare complication.
  • To review existing literature on donor-derived cryptococcal infections in transplant patients.

Main Methods:

  • Case report of a 54-year-old female liver transplant recipient.
  • Diagnosis of meningoencephalitis caused by C. gattii complex.
  • Treatment with amphotericin B and fluconazole.
  • Literature review of donor-derived cryptococcal infections.

Main Results:

  • The patient developed early-onset meningoencephalitis attributed to donor-derived C. gattii.
  • Successful treatment was achieved with a combination of amphotericin B and fluconazole.
  • This represents the first documented case of its kind in a liver transplant recipient.

Conclusions:

  • Donor-derived C. gattii complex infection is a rare but serious complication following liver transplantation.
  • Prompt diagnosis and appropriate antifungal therapy are crucial for favorable outcomes.
  • Awareness of this potential transmission route is important for transplant clinicians.
