Cryptococcosis in organ transplantation

Area of Science:

• Nephrology
• Infectious Diseases
• Transplantation Immunology

Background:

• Opportunistic infections pose a significant risk to graft function and survival post-organ transplantation.
• Fungal infections, particularly invasive ones, contribute substantially to morbidity and mortality in immunocompromised transplant recipients.
• Cryptococcosis is the third most common invasive fungal infection following Candidiasis and Aspergillosis in this patient population.

Observation:

• A 27-year-old male, a live-related renal allograft recipient on immunosuppression for 1.5 years, presented with fever, headache, nausea, and vomiting.
• Clinical evaluation revealed signs consistent with meningitis.
• CT scan showed a swollen third ventricle, and cerebrospinal fluid (CSF) culture confirmed Cryptococcus growth.

Findings:

• The patient was diagnosed with post-renal transplant cryptococcal meningitis.
• Despite treatment with Injection Amphotericin B and supportive care, the patient deteriorated, experienced coma, and died shortly after diagnosis.

Implications:

• Cryptococcal meningitis represents a critical and often fatal complication in immunocompromised organ transplant recipients.
• This case underscores the severe threat posed by invasive fungal infections to graft survival and patient mortality.
• Effective management strategies and heightened clinical suspicion are vital for addressing cryptococcosis in transplant patients.
