Introduction:
Progressive multifocal leukoencephalopathy (PML) is an opportunistic infection of the central nervous system, occurring in immunocompromised patients. Treatment, not codified to date, is more often inefficient with a rapid and fatal deterioration.
Case Record:
A 48-year-old woman, treated with immunosuppressant agents for systemic lupus, presented with PML mimicking neurolupus flare. A complete remission was obtained with cytarabine and cidofovir.
Conclusion:
Combined cytarabine and cidofovir appears a promising therapeutic option in PML associated with autoimmune systemic disorders.
Insights
Progressive multifocal leukoencephalopathy (PML), a rare brain infection in immunocompromised individuals, can mimic autoimmune flares. Combined cytarabine and cidofovir showed promise for treating PML in a patient with systemic lupus erythematosus.
Area of Science:
- Neuroimmunology
- Infectious Diseases
Background:
- Progressive multifocal leukoencephalopathy (PML) is a severe opportunistic CNS infection.
- PML affects immunocompromised patients, often leading to rapid deterioration.
- Current PML treatments are largely ineffective and lack standardization.
Observation:
- A 48-year-old woman with systemic lupus erythematosus presented with PML.
- Her PML symptoms mimicked a neurolupus flare, complicating diagnosis.
- The patient was undergoing immunosuppressive therapy for lupus.
Findings:
- A combination therapy of cytarabine and cidofovir was administered.
- Complete remission of PML was achieved in the patient.
- This treatment approach proved effective for PML in this case.
Implications:
- Combined cytarabine and cidofovir represent a potential therapeutic strategy for PML.
- This approach is particularly relevant for PML cases associated with autoimmune disorders.
- Further research is warranted to validate this treatment for PML in similar patient populations.
