BACKGROUND Knowledge about vertical transmission of HCV is still limited. In this study we followed up the virological status of a series of offspring born to anti-HCV positive, anti-HIV negative mothers. METHODS Between January 1993 and January 1995, 5000 consecutive, anti-HIV negative pregnant women were screened for anti-HCV (ELISA III) and all(More)
The minimum inhibitory concentrations (MICs) of different antibiotics were determined by a broth microdilution method for staphylococci, enterococci and Clostridium difficile. The antimicrobial agents tested were vancomycin, teicoplanin, daptomycin, ramoplanin, MDL 62873, rifampicin and piperacillin, the latter limited to enterococci. In terms of MIC90S,(More)
Non-diabetic glomerulonephritis is a frequent cause of end-stage renal disease. The use of renin–angiotensin–aldosterone system blockers is a fundamental therapeutic approach. However, converting enzyme inhibitors (ACE-is) and angiotensin receptor blockers do not always achieve the desired target of proteinuria. The induction of the prorenin and renin(More)
We studied the production within the CNS of anti-HIV antibodies, of non-specific IgG, and the presence of HIV antigens in the serum and CSF of 28 HIV infected patients belonging to group IV in the Center for Disease Control classification. CSF and serum were diluted under optimal conditions to equalize their IgG content, to enable us to better interpret(More)
Cytomegalovirus (CMV) encephalitis in immunologically normal patients is rarely reported in the literature. CMV infection was diagnosed by viral DNA probe techniques on CSF cells in a 32-year-old, immunologically normal male presenting with a severe clinical picture due to encephalitis. Administration of ganciclovir was followed by an immediate improvement(More)
A multicenter survey was performed to evaluate a new semi-automated human immunodeficiency virus fourth generation antibodies and antigen simultaneous assay. This assay showed a sensitivity of 100% and specificity of 99.6% among sera obtained from hospitalized patients or blood donors. Sera obtained from commercially available as well as in-house(More)
In view of the present world-wide diffusion of HIV, we evaluated the possible presence of persons infected by HIV or suffering from AIDS among the patients and staff of two Dialysis Centers. In the past these centers have been found to be at a high risk for HBV infection. The results of this seroepidemiological study, though rather reassuring for the time(More)
Staphylococcal strains obtained from cutaneous swabs of hospital staff and school students of Camiri and Boyuibe and healthy people living in Javillo, Bolivia, were tested for their in-vitro antimicrobial susceptibility. The highest percentages of resistance to the antibiotics tested were found in staphylococcal strains isolated from hospital personnel. All(More)
The factors influencing virological response to first-line combined antiretroviral therapy (cART) in an Italian cohort of HIV-1-infected patients were examined. Eligible patients were those enrolled in a national prospective observational cohort (Antiretroviral Resistance Cohort Analysis), starting first-line cART between 2001 and 2011 and who had at least(More)
The prevalence of specific antibodies to HTLV-III/LAV retrovirus was investigated during 1985 in a large group of subjects at risk for AIDS living in the Florence area. Two hundred and thirty-two of 774 (29.9%) intravenous drug users (IDU), 40 of 164 homosexuals (24.3%), 43 of 147 hemophiliacs (29.2%), 7 of 10 children born from IDU mothers and 4 of 88(More)
