Two forms of human polyomavirus JC (JCV) genome are known based upon the structure of the transcriptional control region (TCR) of the virus: the archetypal form, which is commonly detected in urine, and the rearranged form, which was first detected in brain tissue from progressive multifocal leukoencephalopathy (PML) patients. The latter actually includes a(More)
Peripheral blood leukocytes from immunocompetent and immunocompromised individuals were analyzed for human polyomarivus BK and JC DNA presence. A nested polymerase chain reaction which amplify the transcriptional control region of the genome of both viruses was employed. The immunocompromised patients included bone marrow transplantation recipients and AIDS(More)
OBJECTIVE The goal of the OSCAR programme is to evaluate the performances of genotypic HIV-1 tropism testing in clinical practice using the enhanced sensitivity version of Trofile (ESTA) as reference-assay. METHODS HIV-1 coreceptor-usage was assessed using plasma samples from 406 HIV-1 infected patients by ESTA and by gp120 V3 population-sequencing(More)
OBJECTIVE The DIVA study is aimed at setting up a standardized genotypic tropism-testing on proviral-DNA for the routine clinical diagnostic-laboratory. METHODS Twelve local centres and 5 reference centres (previously cross-validated) were identified. For inter-center validation-procedure, 60 peripheral-blood mononuclear cells (PBMCs) aliquots from 45(More)
Digestive apparatus is a common target of atypical mycobacteriosis in AIDS patients (at least 50% of patients with CD4+ lymphocytes < 50/mm3). We describe the clinical-histological features of two cases of Whipple-like syndrome likely caused by Mycobacterium avium (MAI) (study performed by light and electron microscopy), of one case of infection caused by(More)
OBJECTIVE To evaluate the association between adherence to drugs and morphologic alterations (MOA) in a cohort of HIV-infected patients on HAART. METHOD This was a cross-sectional multicenter cohort study in eight tertiary Clinical Centers of Northern and Central Italy. Consecutive outpatients taking HAART were enrolled from August 2000 to March 2001.(More)
OBJECTIVE To analyze self-reported adherence to antiretroviral regimens containing ritonavir-boosted protease inhibitors, nonnucleoside reverse transcriptase inhibitors (NNRTI), raltegravir, and maraviroc. METHODS Overall, 372 consecutive subjects attending a reference center for HIV treatment in Florence, Italy, were enrolled in the study, from December(More)
OBJECTIVE We adopted an in situ reverse transcriptase polymerase chain reaction method of detecting and determining the frequency of early (E6) gene expression of human papilloma virus type 16 at the individual cell level in a sample of oral exophytic lesions with various degrees of epithelial hyperplasia and dysplasia in immunosuppressed and(More)
Biochemical analysis of the extracellular matrix of human aortas was performed on samples of ascending and descending aortas affected by atherosclerosis in comparison with a control group of nonatherosclerotic aortas. Ulcerated or heavily calcified atheromas were excised and excluded from the analysis in order to differentiate biochemical alterations(More)
