Abstract

Purpose: Cryptococcal meningoencephalitis (CM) in human immunodeficiency virus (HIV)-negative patients are often diagnosed later than in HIV-infected patients, which increases mortality rates concerning the former. Consequently, early diagnosis and treatment are crucial for improving clinical prognosis in HIV-negative patients. This study investigated the utility of magnetic resonance imaging (MRI) in combination with clinical and laboratory findings for early diagnosis of CM in HIV-negative patients.

Methods: This retrospective cohort analysis included consecutive patients diagnosed with central nervous system (CNS) infections. Demographic profiles, laboratory findings, admission symptoms, and MRI findings were assessed. A comparative analysis between CM and other CNS infections was performed.

Results: Twelve HIV-negative patients were diagnosed with CM, while 38 exhibited other CNS infections (two fungal, 23 bacterial, 12 viral, one parasitic). Pseudocysts on MRI (p = 0.002), absence of fever (p = 0.001), headache (p = 0.005), and normal C-reactive protein (CRP) levels (p = 0.020) were specific findings in CM. By applying a cut-off value of one point in combination of pseudocysts, absence of fever, headache, and normal CRP levels in differentiating CM from other CNS infections, the sensitivity and specificity were calculated as 76.3 % and 91.7 %, respectively.

Conclusion: Integrating pseudocysts, absence of fever, headache, and normal CRP levels predicts early CM diagnosis, potentially improving outcomes.

期刊介绍: eNeurologicalSci provides a medium for the prompt publication of original articles in neurology and neuroscience from around the world. eNS places special emphasis on articles that: 1) provide guidance to clinicians around the world (Best Practices, Global Neurology); 2) report cutting-edge science related to neurology (Basic and Translational Sciences); 3) educate readers about relevant and practical clinical outcomes in neurology (Outcomes Research); and 4) summarize or editorialize the current state of the literature (Reviews, Commentaries, and Editorials). eNS accepts most types of manuscripts for consideration including original research papers, short communications, reviews, book reviews, letters to the Editor, opinions and editorials. Topics considered will be from neurology-related fields that are of interest to practicing physicians around the world. Examples include neuromuscular diseases, demyelination, atrophies, dementia, neoplasms, infections, epilepsies, disturbances of consciousness, stroke and cerebral circulation, growth and development, plasticity and intermediary metabolism. The fields covered may include neuroanatomy, neurochemistry, neuroendocrinology, neuroepidemiology, neurogenetics, neuroimmunology, neuroophthalmology, neuropathology, neuropharmacology, neurophysiology, neuropsychology, neuroradiology, neurosurgery, neurooncology, neurotoxicology, restorative neurology, and tropical neurology.
