Myelin basic protein (MBP) was measured in cerebrospinal fluid (CSF) of patients with acquired immunodeficiency syndrome (AIDS) dementia complex (ADC) in order to investigate the degree of white matter destruction. Results show that increased CSF levels of MBP were detected in all patients with severe ADC (10/10) and, less often, in subjects with mild (2/7)(More)
Tumour necrosis factor (TNF-alpha) concentrations were determined in the CSF from 42 HIV-infected patients, with or without CNS involvement. In addition, 14 subjects with various neurological disorders but without HIV antibodies were included as controls. Raised CSF concentrations of TNF-alpha (greater than 40 ng/l) were detected both in patients with AIDS(More)
Matrix metalloproteinases (MMPs) have been identified as mediators of brain injury in HIV-associated neurological diseases. The activity of the 72 kDa gelatinase A (MMP-2) and 92 kDa gelatinase B (MMP-9) was detected by zymography in the cerebrospinal fluid (CSF) of 138 HIV-infected patients (40 with AIDS dementia, 83 with brain opportunistic infections and(More)
The introduction of potent antiretroviral drugs for the treatment of patients with human immunodeficiency virus (HIV) infection has dramatically reduced the prevalence of HIV-associated neurological disorders. Such diseases can be mediated by proteolytic enzymes, i.e. matrix metalloproteinases (MMPs) and, in particular gelatinases, released from glial(More)
Degradation of purified myelin basic protein (MBP) was studied by SDS gel electrophoresis after addition of CSF samples obtained from HIV-1-infected patients. An increase in MBP degradation was detected in patients with neurological complications, such as AIDS dementia complex (ADC) or progressive multifocal leukoencephalopathy (PML), when compared with(More)
The relationship between tumour necrosis factor-alpha (TNF-alpha) and the interleukin-2 (ILL-2) system in HIV-1 infection is important in understanding the dynamics of early immune response before the development of acquired immunodeficiency syndrome. Levels of TNF-alpha, IL-2 and soluble IL-2 receptor (sIL-2R) in serum and cerebrospinal fluid (CSF) samples(More)
As reliable data on Chlamydia trachomatis infection in Italy are lacking and as there is no Italian screening policy, epidemiological analyses are needed to optimise effective strategies for surveillance of the infection in the country. We collected data from 6,969 sexually active women aged 15 to 55 years who underwent testing for endocervical C.(More)
Relapsing and disseminated VZV infection associated with post-zoster neuralgia in an HIV-infected patient Sir: We describe a new case of post-zoster neuralgia in a patient infected with human immunodeficiency virus (HIV) and with relapsing disseminated varicella-zoster virus (VZV) disease. The clinical presentation and course of post-zoster neuralgia vary(More)
