Brain damage after meningeal infection could result from impairment of cerebral endothelial cell functions and disruption of blood-brain barriers. Tumor necrosis factor-alpha (TNF alpha) and interleukin-1 beta (IL-1 beta) produce many of their effects by acting on endothelial cells. This study correlates levels of TNF alpha and IL-1 beta in paired(More)
It is well accepted that the molecular charge and conformation of serum proteins are major determinants of their glomerular filtration, but few studies characterizing the molecular features of circulating proteins in renal diseases are currently available. In 11 children affected by minimal change nephropathy (MCN) we determined the electrical charge and(More)
The mechanism for the initiation of blood-brain barrier damage and intrathecal inflammation in multiple sclerosis (MS) is poorly understood. We have recently reported that levels of tumor necrosis factor-alpha (TNF-alpha) correlate with blood-brain barrier damage in patients with active MS. Stimulation of endothelial cells by TNF-alpha induces the(More)
A novel multiplex nested PCR (nPCR) method was developed for detecting and differentiating simultaneously the DNA of polyomaviruses JC, BK and SV40 in a single tube. In the first amplification step the same set of primers were used to amplify a conserved DNA region of the large T antigen gene of JCV, BKV and SV40. The second round of multiplex nPCR was(More)
A study of 371 women (261 asymptomatic and 110 symptomatic subjects with clinical PID) was performed to detect the presence of Chlamydia trachomatis (C.t.) and to correlate the serological markers against this microrganism, such as antibody to chlamydial hsp60 (Ab-Chsp60) and different levels of IgG, IgM and IgA, with epidemiology, pathology, sexual habits,(More)
BACKGROUND Although a growing body of literature regarding polyoma BK virus (BKV) infection and associated interstitial nephritis in kidney-allograft recipients is becoming available, the impact of BKV infection in the pediatric population has not been fully evaluated. METHODS In a retrospective analysis, we performed polymerase chain reaction (PCR)(More)
OBJECTIVES: To evaluate the rate of discordance between patients and physicians on adherence to highly active antiretroviral therapy (HAART) and identify factors related to discordance in these two assessments. DESIGN: Prospective, multicenter, cohort study (AdICONA) nested within the Italian Cohort Naïve Antiretrovirals (ICONA) study. SETTING: Tertiary(More)
BACKGROUND Although efavirenz (EFV) and lopinavir/ ritonavir (LPV/r) are both recommended antiretroviral agents for combination therapy in drug-naive HIV-infected patients, no randomized comparison of their efficacy and tolerability is available yet. A multi-cohort prospective observational comparative study was performed. METHODS Efficacy was examined(More)
John Cunningham virus (JCV), the etiological agent of progressive multifocal leukoencephalopathy (PML), contains a hyper-variable non-coding control region usually detected in urine of healthy individuals as archetype form and in the brain and cerebrospinal fluid (CSF) of PML patients as rearranged form. We report a case of HIV-related PML with clinical,(More)
The human polyomavirus JC (JCV) is the causative agent of progressive multifocal leukoencephalopathy (PML), a fatal demyelinating disease of the central nervous system (CNS). JCV has a hyper-variable non-coding transcriptional control region (TCR), which contains the origin of replication and the promoters of viral transcription and replication. The(More)
