[Primary central nervous system lymphomas in AIDS patients]

Area of Science:

• Neuro-oncology
• Infectious diseases
• Immunology

Context:

• Primary central nervous system (CNS) lymphoma is the most frequent neoplasm in individuals with acquired immunodeficiency syndrome (AIDS).
• Understanding the characteristics and outcomes of primary CNS lymphoma in HIV/AIDS patients is crucial for improving patient care.

Purpose:

• To retrospectively review the clinical, neuroimaging, diagnostic, and histological features of primary CNS lymphoma in HIV/AIDS patients.
• To determine the association of Epstein-Barr virus (EBV) with primary CNS lymphoma in this population.
• To evaluate the prognosis and survival rates of patients diagnosed with primary CNS lymphoma.

Summary:

• The study reviewed 18 HIV/AIDS patients with primary CNS lymphoma, finding an overall incidence of 2.6%.
• Common clinical findings included focal neurological deficits and seizures, with a mean CD4 T cell count of 44 cells/microl.
• Large lesions (> 2.5 cm) with mass effect were typical. Epstein-Barr virus (EBV) DNA was detected in brain smears and cerebrospinal fluid (CSF) in most cases.
• Median survival after diagnosis was 75 days, indicating a poor prognosis.

Impact:

• This study reinforces the link between EBV and primary CNS lymphoma in AIDS patients.
• The findings highlight the aggressive nature and poor survival associated with primary CNS lymphoma in this vulnerable population.
• Results underscore the need for early diagnosis and targeted therapeutic strategies for primary CNS lymphoma in HIV/AIDS patients.
