Abstract:
Progressive multifocal leukoencephalopathy (PML), a subacute and usually fatal demyelinating disease of the brain, is caused by an opportunistic viral infection in immunocompromised patients. Only one case of PML after heart transplantation has been reported; it was discovered at the autopsy of a patient who died of multiorgan system failure. We describe an otherwise asymptomatic heart transplant recipient who had neurologic complaints that could be specifically attributed to PML, demonstrate the pertinent pathologic findings, and review the PML literature germane to heart transplantation. PML may become more prevalent as the population of heart transplant recipients increases.
Insights
Progressive multifocal leukoencephalopathy (PML) is a rare brain infection in immunocompromised patients. This case highlights PML in a heart transplant recipient, suggesting increased prevalence with more transplants.
Area of Science:
- Neurology
- Immunology
- Infectious Diseases
Background:
- Progressive multifocal leukoencephalopathy (PML) is a fatal demyelinating disease caused by opportunistic viral infection in immunocompromised individuals.
- PML is rare post-heart transplantation, with only one prior reported case found at autopsy.
Observation:
- This report details a heart transplant recipient who presented with neurological symptoms attributable to PML.
- The patient was otherwise asymptomatic, underscoring the potential for PML to manifest clinically in this population.
Findings:
- The study describes the specific pathological findings of PML in the heart transplant recipient.
- A review of existing literature on PML in the context of heart transplantation is provided.
Implications:
- PML may become more frequently diagnosed in heart transplant recipients as the population grows.
- Early recognition and diagnosis of PML are crucial for managing neurological complications in immunocompromised patients.
