Objectives: The long-term virological efficacy of lopinavir/ritonavir-containing highly active antiretroviral therapy (HAART) in HIV-infected patients failing a first-line protease inhibitor (PI)-based regimen is still unclear. Methods: An observational study was carried out from December 2000-December 2002 on 111 consecutive patients starting...

Objectives: To explore the durability of three first-line tenofovir/emtricitabine-based regimens in combination with atazanavir/ritonavir, efavirenz or lopinavir/ritonavir in HIV-1-infected patients. Patients and methods: A retrospective, longitudinal, multicentre analysis of adult patients enrolled in the Antiretroviral Resistance Cohort...

We evaluated the efficacy of tenofovir (TDF) - and didanosine (ddI)-containing backbones in HIV-infected experienced subjects. We included in the study 245 subjects who started a TDF/ddI-containing HAART with HIV-RNA > 3 log10 cp/ml and an available genotypic resistance test at baseline. At baseline, median CD4 counts and HIV-RNA were 278...

Background: Long term efficacy of raltegravir (RAL)-including regimens in highly pre-treated HIV-1-infected patients has been demonstrated in registration trials. However, few studies have assessed durability in routine clinical settings. Methods: Antiretroviral treatment-experienced patients initiating a RAL-containing salvage regimen were...

Background: Immunological non-responders (INRs) lacked CD4 increase despite HIV-viremia suppression on HAART and had an increased risk of disease progression. We assessed immune reconstitution profile upon intensification with maraviroc in INRs. Methods: We designed a multi-centric, randomized, parallel, open label, phase 4 superiority trial....

Objectives: The objective of this study was to assess the 48-week virological efficacy of atazanavir/ritonavir (ATV/r) monotherapy vs. ATV/r along with two nucleoside reverse transcriptase (NRTIs) in HIV-1 treated individuals with HIV-RNA less than 50 copies/ml. Methods: A multicentre, randomized, open-label, noninferiority trial. HIV-1 treated...

Objectives: The aim was to evaluate the evolution of transmitted HIV-1 drug resistance (TDR) prevalence in antiretroviral therapy (ART)-naïve patients from 2006 to 2016. Methods: HIV-1 sequences were retrieved from the Antiviral Response Cohort Analysis (ARCA) database and TDR was defined as detection of at least one mutation from the World...

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...

Introduction: Concerns about dolutegravir (DTG) tolerability in the real-life setting have recently arisen. We aimed to estimate the risk of treatment discontinuation and virological failure of DTG-based regimens from a large cohort of HIV-infected individuals. Methods: We performed a multicentre, observational study including all...

Objectives: To investigate the long-term safety and efficacy of a treatment switch to dual ART with atazanavir/ritonavir+lamivudine versus continuing a standard regimen with atazanavir/ritonavir+2NRTI in virologically suppressed patients. Methods: ATLAS-M is a 96 week open-label, randomized, non-inferiority (margin -12%) trial enrolling...
