OBJECTIVE: To analyze the clinical characteristics of patients with acute immunodeficiency syndrome (AIDS) combined with Talaromyces marneffei (TM) infection of the central nervous system (CNS), thereby improving awareness toward early diagnosis and treatment.
METHODS: The clinical data of eight patients with AIDS who were treated for CNS TM infection in the Guiyang Public Health Treatment Center from May 2021 to November 2022 were retrospectively analyzed.
RESULTS: The median age of the patients was 43.50 (range: 35.00-58.00) years, and all eight were male. TM infection was confirmed via metagenomic next-generation sequencing (mNGS) in three cases, positive cerebrospinal fluid (CSF) cultures of TM in four cases, and both in one case. CSF and blood cultures were both positive for one patient, whereas multiple blood cultures were negative for the other seven. The number of nucleated cells and the protein level in the CSF were elevated in five and six patients, respectively, and the CSF levels of glucose and chloride were low in four patients each. Seven patients had intracranial lesions upon head imaging, and all eight were discharged from the hospital with improvement after antifungal treatment. The median CD4+ T-cell count was 58.50/μL (range: 39.00-73.00/μL), indicating severe immunosuppression.
CONCLUSION: The clinical characteristics and CSF-related examinations of patients with AIDS combined with CNS TM infection are not distinct, complicating diagnosis and increasing the likelihood of misdiagnosis. Early diagnosis and systemic antifungal therapy can improve patients' prognosis.
