ABSTRACT: Serum samples collected since 1989 with various patterns of reactivity for human immunodeficiency virus (HIV)-1, on the basis of screening ELISA and confirmatory Western blot (WB) test, were subjected to the detection of HIV-2 infection based on screening dot immunoassay and confirmatory WB for HIV-2. Significant prevalence of HIV-2 infection was (37.03%) among sera reactive for HIV-1 by ELISA but indeterminate by Western blot, compared with sera reactive for HIV-1 by ELISA and WB (3.29%) or negative by WB (2.63%). Out of 16 HIV-2 positive sera, 5 (31.25%) showed evidence of concomitant HIV-1 infection. This study demonstrates evidence of HIV-2 infection as early as 1989, earlier than reported so far from India.The Indian Journal of Medical Research 04/1996; 103:131-3. · 2.06 Impact Factor

ABSTRACT: The aim of the study was to determine the prevalence of HIV-related neurological disorders in HIV positive patients and its relationship to CD4 cell counts in Georgia. This study included 388 HIV/AIDS patients (302 men and 86 women), who have been admitted to the in-patient Department of Infectious Diseases, AIDS and Clinical Immunology Research Center (IDACIRC) of Georgia since 2006. Diagnosis of neurological disorders was made based on clinical symptoms and instrumental-laboratory investigations. CNS Neurological complications were detected in 76 patients; 13 patients had two or more neurological complications. Tuberculosis meningitis were the most common neurological disorders 26 (34%), followed by CNS toxoplasmosis 17 (22%), cryptococcal meningitis 11 (15%), presumed CMV encephalitis 5 (7%), PML 4 (5%), primary CNS lymphoma 4 (5%) and bacterial meningitis 3 (4%). AIDS related dementia was detected in 18 patients (24%). The median CD4+ T lymphocyte count was 47 cells/mm(3) (range: 2-183 cells/mm(3)) in HIV patients with neurological complications. There was correlation between the CD4 T lymphocyte count and type of neurological manifestation. Namely, in the patients with HIV related dementia median CD4 T lymphocyte count was 164 cells/mm(3), in the patients with CNS toxoplasmosis median CD4 count was 83 cells/mm(3), in the patients with cryptococcal meningitis median CD4 T lymphocyte count was 34 cells/mm(3) and in the patients with CMV encephalitis median CD4 T lymphocyte count was 26 cells/mm(3). Some neurological disorders such as TB meningitis and bacterial meningitis can occur at any CD4 level. PML and primary CNS lymphoma occurred when CD4 T lymphocyte count < 50 cells/mm(3). The most common clinical manifestations of neurological disorders in HIV infected patients were headache (91%), fever (75%), focal neurological deficits (61%), speech disturbances (42%), cognitive dysfunction (41%), visual disturbances (36%), impaired coordination (29%) and seizures (15%). The study provide convincing evidence that neurological disorders with HIV infection might serve as an indicator for advanced HIV infection, immunosuppression and decreased CD4 cell counts. Our data have shown correlation between the type of neurological manifestations of HIV infection and CD4 T lymphocyte count.Georgian medical news 12/2008;

ABSTRACT: Subacute encephalitis, characterized by demyelination, gliosis of the gray and white matter, focal necrosis, microglial nodules, atypical oligodendrocyte nuclei, and multinucleation of cells, was present in 27 of 30 (90%) autopsied patients with acquired immune deficiency syndrome (AIDS) or AIDS-related complex. Subacute encephalitis was mainly distributed in the frontal (58%) and temporal (69%) lobes, basal ganglia (77%), amygdala (80%), and hippocampus (64%). Ten (37%) with moderate or severe subacute encephalitis were demented; 82% with mild subacute encephalitis had no recognized neurologic disorder. Human T-lymphotropic virus type III (HTLV-III) was isolated from neural tissue or CSF in 11 of 13 patients, 10 with subacute encephalitis, and 1 without CNS lesions. We conclude that subacute encephalitis is common in AIDS patients and is most likely caused by CNS infection with HTLV-III.Neurology 05/1987; 37(4):562-9. · 8.25 Impact Factor
