Background:
Central nervous system fungal infections (FI) are important complications and a cause of mortality in patients who receive hematopoietic stem cell transplantation (HSCT).
Aims:
To study the clinical aspects of fungal encephalitis (FE).
Settings And Design:
The study was carried out at the HSCT Center of the Hospital de Clínicas, Federal University of Paraná, Curitiba, Brazil.
Materials And Methods:
Clinical records and autopsy reports from patients submitted to HSCT with a diagnosis of FE.
Results:
Twelve patients were diagnosed with FE presenting with lowered level of consciousness, hemiparesis and seizures. We were able to identify two subgroups regarding susceptibility to FE: (1) patients with early onset FI and severe leucopenia, and (2) patients with later onset FI with graft-versus-host disease using immunosuppressive drugs. Eleven of the patients died directly due to the neurological complication, all had post-mortem confirmation of the diagnosis of FI.
Conclusions:
These clinical, paraclinical and temporal patterns may provide the opportunity for earlier diagnosis and interventions.
Insights
Fungal encephalitis (FE) is a severe complication after hematopoietic stem cell transplantation (HSCT), often leading to mortality. Identifying clinical patterns may enable earlier diagnosis and intervention for these central nervous system fungal infections.
Area of Science:
- Neurology
- Infectious Diseases
- Hematology
Background:
- Central nervous system fungal infections (FI) are critical complications in hematopoietic stem cell transplantation (HSCT) recipients.
- These infections contribute significantly to mortality in this vulnerable patient population.
Purpose of the Study:
- To investigate the clinical characteristics of fungal encephalitis (FE).
- To identify patterns associated with FE development in HSCT patients.
Main Methods:
- Retrospective analysis of clinical records and autopsy reports.
- Study conducted at the HSCT Center of the Hospital de Clínicas, Federal University of Paraná, Brazil.
Main Results:
- Twelve HSCT patients diagnosed with fungal encephalitis presented with altered consciousness, hemiparesis, and seizures.
- Two susceptibility subgroups identified: early-onset FI with severe leucopenia, and late-onset FI with graft-versus-host disease on immunosuppressants.
- Eleven patients died from neurological complications, with post-mortem confirmation of FI.
Conclusions:
- Recognizing clinical, paraclinical, and temporal patterns of FE is crucial.
- These patterns offer potential for earlier diagnosis and timely interventions in HSCT patients.
