✦ Synopsis

Abstract

Two hundred twenty‐four sera were collected from 34 HIV‐1 infected patients during an observation period of up to 4.5 years (109 patient years of observation). The sera were tested for the presence of antibodies against the HIV‐1 virion infectivity factor (vif) protein. Thirty sera from 6 HIV‐1 seronegative individuals served as negative controls. The sera were immunoblotted against a recombinant, prokaryotically expressed vif protein. The prevalence of anti‐vif antibodies increased significantly with progression of the disease from 18% to 81% (P < 0.0001) which suggests a possible role of vif in HIV‐1 replication and pathogenicity.

## Abstract The prevalence of antibody to hepatitis C virus (HCV) in a cohort of 272 HIV‐infected patients was assessed by means of 4 anti‐HCV assays: a 1st generation and a neutralization test, a 2nd generation test, and a confirmatory test, the dot‐blot Matrix HCV™ immunoassay. The cohort include

## Abstract Heat shock proteins (Hsp), especially 70 kDa heat shock protein (Hsp70) play an important role in the life cycle of HIV‐1 virus. Hsp70 is overexpressed in HIV‐infected cells and this is the most abundant Hsp associated with HIV virions. The aim of our study was to investigate whether HI

Baseline genotype resistance analysis was carried out in 48 adults with primary HIV-1 infection between 1995 and 1998 before starting early combination therapy. Seventeen percent (8/48) of the isolates displayed key mutations conferring resistance to reverse transcriptase (RT) inhibitors such as ami
