CASTANO-OSORIO, Jhon Carlos et al. Determination of clinical and epidemiological features of neuroinfection in patients with diagnosis of HIV-AIDS in the department of Quindío. Infect. [online]. 2007, vol.11, n.4, pp.173-182. ISSN 0123-9392.

Objective: To describe clinical, epidemiological and etiological characteristics of neuroinfection in HIV patients from Quindío department. Materials and methods: A descriptive-prospective study was carried out in HIV positive patients with neuroinfection suspicion from a third level ESE of Armenia. In Quindío department have not been reported diagnostic protocols that correlate the cost-benefit of the various schemes of handling patients with HIV infection associated with the central nervous system (CNS). All the patients that consulted the third level ESE of Armenia with two positive anti-HIV ELISA tests or positive a Western Blot test with suspicion of concomitant CNS illness. The following laboratory tests were performed in cerebrospinal fluid (CSF): VDRL, Chinese ink, Ziehl-Nielsen stain, fungi cultures, CMV and Herpes simplex PCR, serum IgG anti-Toxoplasma, andCryptococcal Antigen Latex Agglutination System (CALAS); a simple cerebral CT scan was taken to all patients. Results: 85.7% of the patients were men; the age rank was between 23 and 68 years. The most frequently found symptoms were: fever, consciousness and orientation compromise, paresis, paresthesia, cranial pairs compromise, and altered neurological reflexes. 89% of the patients with brain space occupying lesions were IgG anti-Toxoplasma positive( values between 155 and 887.2 UI/ml) and the antibodies values in patients without cerebral lesion in the simple cerebral CT scan oscillated between 13.8 and 36 UI/ml. Discussion: Simple cerebral CT scan, serum IgG anti-Toxoplasma and staining of CSF with Chinese ink allowed the diagnosis of 85% of the patients
