Transmission patterns of HIV-1 non-R5 strains in Poland.

HIV-1 env sequencing enables predictions of viral coreceptor tropism and phylogenetic investigations of transmission events. The aim of the study was to estimate the contribution of non-R5 strains to the viral spread in Poland. Partial proviral env sequences were retrieved from baseline blood samples of patients with newly diagnosed HIV-1 infection between 2008-2014, including 46 patients with recent HIV-1 infection (RHI), and 246 individuals with long-term infection (LTHI).

Long-term effectiveness of recommended boosted protease inhibitor-based antiretroviral therapy in Europe.

Objectives: The aim of the study was to evaluate the long-term response to antiretroviral treatment (ART) based on atazanavir/ritonavir (ATZ/r)-, darunavir/ritonavir (DRV/r)-, and lopinavir/ritonavir (LPV/r)-containing regimens.

Methods: Data were analysed for 5678 EuroSIDA-enrolled patients starting a DRV/r-, ATZ/r- or LPV/r-containing regimen between 1 January 2000 and 30 June 2013. Separate analyses were performed for the following subgroups of patients: (1) ART-naïve subjects (8%) at ritonavir-boosted protease inhibitor (PI/r) initiation; (2) ART-experienced individuals (44%) initiating the new PI/r with a viral load (VL) ≤500 HIV-1 RNA copies/mL; and (3) ART-experienced patients (48%) initiating the new PI/r with a VL >500 copies/mL.

HIV-1 Infection in Persons Homozygous for CCR5-Δ32 Allele: The Next Case and the Review.

CC-chemokine receptor 5 serves as the coreceptor for the HIV-1 R5 strains, which are responsible for the majority of HIV transmissions. A deletion of 32 nucleotides in the gene encoding this receptor (termed CCR5-Δ32) leads to the suppression of CC-chemokine receptor 5 presentation at the cell surface, thus impeding process of HIV entry into the cell. Individuals homozygous for the CCR5-Δ32 allele are resistant to infection with HIV-1 R5 strains, and are extremely rare among HIV-1-infected individuals.

Prevalence of Transmitted Drug-Resistance Mutations and Polymorphisms in HIV-1 Reverse Transcriptase, Protease, and gp41 Sequences Among Recent Seroconverters in Southern Poland.

BACKGROUND Monitoring of drug resistance-related mutations among patients with recent HIV-1 infection offers an opportunity to describe current patterns of transmitted drug resistance (TDR) mutations. MATERIAL AND METHODS Of 298 individuals newly diagnosed from March 2008 to February 2014 in southern Poland, 47 were deemed to have recent HIV-1 infection by the limiting antigen avidity immunoassay. Proviral DNA was amplified and sequenced in the reverse transcriptase, protease, and gp41 coding regions.

Effectiveness data of an unboosted atazanavir (ATV) with abacavir/lamivudine (ABC/3TC) switch strategy in clinical routine are scant.We evaluated treatment outcomes of ATV + ABC/3TC in pretreated subjects in the EuroSIDA cohort when started with undetectable plasma HIV-1 viral load (pVL), performing a time to loss of virological response (TLOVR <50 copies/mL) and a snapshot analysis at 48, 96, and 144 weeks. Virological failure (VF) was defined as confirmed pVL >50 copies/mL.

Long term effectiveness of once-daily unboosted atazanavir plus abacavir/lamivudine as a switch strategy in subjects with virological suppression.

Background: Use of unboosted atazanavir (ATV400) is approved in the US but not in Europe (1). Due to pharmacokinetic interactions it should not be used with tenofovir but can be used with abacavir/lamivudine (ABC/3TC) (1, 2) (3). Effectiveness data of ATV400+ABC/3TC as a switch strategy in clinical routine however are scant.

A comparison of estimated glomerular filtration rates using Cockcroft-Gault and the Chronic Kidney Disease Epidemiology Collaboration estimating equations in HIV infection.

Objectives: All HIV/hepatitis C virus (HCV)-coinfected patients with chronic HCV infection and ≥ F2 fibrosis should be considered for HCV therapy. This study aimed to determine the rate of HCV treatment uptake among coinfected patients in Europe.

Methods: EuroSIDA patients with viraemic HCV infection were included in the study.

Transmission of drug-resistant HIV-1 variants among individuals with recent infection in southern Poland.

Transmitted drug resistance (TDR) is an important public health issue, because it may affect the outcome of antiretroviral treatment. The prevalence of human immunodeficiency virus type 1 (HIV-1) with TDR mutations defined according to the list of the World Health Organization was investigated among 53 therapy-naïve persons with confirmed recent HIV-1 infection diagnosed in Poland, in the years 2008-2010. Proviral DNA was amplified, sequenced, and screened for the TDR mutations in the pol gene fragments coding for the whole protease and the initial 256 residues of the reverse transcriptase.

Does hepatitis C viremia or genotype predict the risk of mortality in individuals co-infected with HIV?

Background & Aims: The influence of HCV-RNA levels and genotype on HCV disease progression is not well studied. The prognostic value of these markers was investigated in HIV/HCV co-infected individuals from the EuroSIDA cohort.

Methods: EuroSIDA is a prospective cohort of 18,295 HIV-1 infected patients in 105 centres across Europe, Israel, and Argentina.

Objectives: This study aimed to determine incidence rates (IR) and identify risk factors for severe bacterial non-AIDS infections (SBnAI) requiring hospital admission.

Methods: Data from the prospective EuroSIDA cohort were utilized to determine IRs of first diagnosis of the following SBnAI requiring hospital admission: bacteremia, endocarditis, meningitis, peritonitis, pneumonia, osteitis, and pyolonephritis. Incidence rate-ratios (IRRs) and risk factors were assessed by Poisson regression.

Molecular epidemiology of recent HIV-1 infections in southern Poland.

The genetic diversity of human immunodeficiency virus type 1 (HIV-1) offers an opportunity to track the development of the epidemic across different populations. Viral pol gene fragments from 55 individuals of Polish origin with recent HIV-1 infection identified in 2008-2010 in four Polish cities were analyzed. Viral sequences were compared with sequences from 100 individuals (reference group) infected before 2004.

Estimating prevalence of accumulated HIV-1 drug resistance in a cohort of patients on antiretroviral therapy.

Objectives: Estimating the prevalence of accumulated HIV drug resistance in patients receiving antiretroviral therapy (ART) is difficult due to lack of resistance testing at all occasions of virological failure and in patients with undetectable viral load. A method to estimate this for 6498 EuroSIDA patients who were under follow-up on ART at 1 July 2008 was therefore developed by imputing data on patients with no prior resistance test results, based on the probability of detecting resistance in tested patients with similar profiles.

Methods: Using all resistance test results available, predicted intermediate/high-level resistance to specific drug classes [nucleoside reverse transcriptase inhibitors (NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs) and protease inhibitors (PIs)] was derived using the Stanford algorithm v5.
