[Neurological complications with HIV infection].

Human immunodeficiency virus (HIV) induces acquired immunodeficiency syndrome (AIDS) in humans. Neurological complications occur frequently in patients with AIDS. About 20 to 40% of all these patients develop neurological symptoms, and in about 10% of AIDS patients, the onset of the disease is characterized by neurological symptoms.

Cerebrospinal fluid interferon-gamma-inducible protein 10 (IP-10, CXCL10) in HIV-1 infection.

Interferon-gamma-inducible protein (IP-10 or CXCL10) is a potent chemoattractant and has been suggested to enhance retrovirus infection and mediate neuronal injury. In order to assess this chemokine in central nervous system (CNS) HIV infection, we measured the cerebrospinal fluid (CSF) and plasma concentrations of CXCL10 by immunoassay in samples derived from 97 HIV-infected subjects across a spectrum of immunological progression and CNS complications and from 16 HIV seronegative control subjects studied at three clinical centers between 1994 and 2001. We also examined changes in the CSF and plasma CXCL10 concentrations in 30 subjects starting and three stopping antiretroviral therapy.

[Secondary diseases in patients with HIV infection: 15-year follow-up].

Aim: To analyse the results of a 15-year study of opportunistic diseases in AIDS patients.

Material And Methods: The spectrum of opportunistic diseases were made in AIDS patients in respect to clinical, laboratory and autopsy data for the periods: 1987-1992 (n = 27, 25 deaths--92.6%), 1993-1997 (n = 95, 58 deaths--61.

[Utility of quantitation of human cytomegalovirus(HCMV) DNA in plasma and cerebrospinal fluid by quantitative competitive PCR in AIDS patients].

Persons with advanced HIV infection may have active HCMV infection for months before clinically recognized HCMV disease. The qualitative detection of HCMV-DNA in plasma by PCR is more useful than either urine or blood culture in identifying over time those persons with advanced HIV disease who will develop HCMV disease. Quantitation of HCMV DNA in plasma has identified an association between levels of HCMV DNA in plasma and risk for development of HCMV disease.

Central nervous system opportunistic infections.

The spectrum of opportunistic infections occurring in association with human-immunodeficiency virus, type 1, is very broad. These infections develop most frequently in the setting of advanced immunosuppression. There is no part of the neuraxis that is immune to these complications and the concurrence of more than one infectious illness may always be considered.

AIDS-associated cytomegalovirus infection mimicking central nervous system tumors: a diagnostic challenge.

We reviewed cases of cytomegalovirus (CMV) infection of the central nervous system (CNS) that initially masqueraded as tumors in 37 of 543 consecutive patients infected with human immunodeficiency virus (HIV) and CMV who were seen at the Pasteur Institute Hospital and Saint-Louis Hospital (Paris) between 1992 and 1994. We detail the clinical features of three patients who presented with ring-enhanced space-occupying lesions mimicking CNS tumors. They were all profoundly immunodepressed (mean CD4 cell count, 13/mm3).

Prospective analysis of seizures occurring in human immunodeficiency virus type-1 infection.

A prospective, case-control study was undertaken to characterise seizures occurring in the context of human immunodeficiency type-1 (HIV-1) infection. Fifty consecutive patients with a documented seizure were enrolled along with fifty control patients. Among cases the median CD4 cell count was 8/mm3 and 84% had a prior AIDS defining illness; 14/mm3 and 80% among the control group.

Comparative analysis of intrathecal antibody synthesis and DNA amplification for the diagnosis of cytomegalovirus infection of the central nervous system in AIDS patients.

We evaluated 49 paired cerebrospinal fluid (CSF) and serum samples of 35 patients infected with the human immunodeficiency virus type 1 (HIV-1) for laboratory evidence of cytomegalovirus (CMV) infection. The patients were grouped according to clinical criteria as probable CMV encephalitis/polyradiculomyelitis, CMV retinitis, cerebral toxoplasmosis, progressive multifocal leukoencephalopathy, HIV-1-related cognitive/motor complex, HIV-1-associated myelopathy, and other neurological diseases. Paired CSF and serum samples were analysed for CMV deoxyribonucleic acid (DNA) by polymerase chain reaction (PCR), quantitative intrathecal synthesis of immunoglobulin G (IgG) antibodies specific for recombinant phosphoprotein 150 (pp150) of CMV and CMV-specific serum IgM.

The mortality and pathology of HIV infection in a west African city.

Background: HIV disease is epidemic in Africa, but associated mortality, underlying pathology and CD4+ T-lymphocyte counts have not previously been evaluated in a representative study. Such data help to determine the management of HIV-positive people. Both HIV-1 and HIV-2 infections are prevalent in Côte d'Ivoire, and the pathology of HIV-2 infection in Africa is unclear.

[The neuropathology of the acquired immunodeficiency syndrome (AIDS)].

The nervous system is frequently involved in patients with AIDS. The lesions can be due to the human immunodeficiency virus (HIV), to opportunistic agents, to the development of tumours, and to occasional nonspecific factors, such as circulatory, metabolic and degenerative changes. The changes directly related to the presence of the HIV include the HIV encephalitis and leucoencephalopathy, the diffuse polydystrophy and the vacuolar myelopathy.

Neuropathology of the acquired immune deficiency syndrome (AIDS): report of 39 autopsies from Vancouver, British Columbia.

Neuropathological findings from 39 acquired immune deficiency syndrome (AIDS) autopsies of primarily neurologically symptomatic patients and 7 brain biopsies from AIDS patients performed at St. Paul's Hospital, Vancouver, British Columbia are reported. Autopsy findings included human immunodeficiency virus-1 (HIV)-type multinucleated giant cell (MNGC)-associated encephalitis seen in 17 patients, toxoplasmosis in 7 patients, and cytomegalovirus encephalitis and/or microglial nodule-associated nuclear inclusions in brain parenchyma in 9 patients.
