Journal ArticleDOI
Absolute quantitation of viremia in human immunodeficiency virus infection by competitive reverse transcription and polymerase chain reaction.
TL;DR: A competitive polymerase chain reaction (PCR)-based assay for the quantitative detection of human immunodeficiency virus type 1 (HIV-1) viremia was developed and optimized and proved to be useful in the quantitative assay of HIV-1-specific cellular transcripts and proviral DNA sequences from peripheral blood mononuclear cells by using competitor DNA.
Journal ArticleDOI
Human case of autochthonous West Nile virus lineage 2 infection in Italy, September 2011.
Patrizia Bagnarelli,K Marinelli,D Trotta,Alessia Monachetti,M Tavio,R Del Gobbo,Maria Rosaria Capobianchi,Stefano Menzo,Loredana Nicoletti,Fabio Magurano,P. E. Varaldo +10 more
TL;DR: Genomic sequencing of the viral isolate showed that the virus belonged to WNV lineage 2, and detected WNV-specific IgM and IgG antibodies in the patient's serum.
Journal ArticleDOI
Clinical use of quantitative molecular methods in studying human immunodeficiency virus type 1 infection
Massimo Clementi,Stefano Menzo,Patrizia Bagnarelli,Anna Valenza,Stefania Paolucci,Riccardo Sampaolesi,Aldo Manzin,P. E. Varaldo +7 more
TL;DR: The role of Quantitative Methods in HIV-1 Infection, Antiretroviral Therapies and Analysis of HIV- 1 Load are examined.
Journal ArticleDOI
Quantitative molecular monitoring of human immunodeficiency virus type 1 activity during therapy with specific antiretroviral compounds.

TL;DR: Methods for the absolute quantitation of nucleic acids present in small amounts in biological samples were applied to the direct monitoring of specific anti-human immunodeficiency virus type 1 (HIV-1) therapy and circulating viral variants bearing at least two mutations compatible with azidothymidine or ddI resistance were detectable in patients.
Journal ArticleDOI
Human immunodeficiency virus type 1 and hepatitis B virus transcription in peripheral blood lymphocytes from co-infected subjects.
TL;DR: The data shown here are an extension of previous reports documenting HBV and HIV-1 co-infection of PBLs and indicate that transcriptionally active HBV infection of P BLs is detectable in a significant proportion of asymptomatic HIV- 1 infected patients.
