Effectiveness of dolutegravir-based regimens as either first-line or switch antiretroviral therapy: data from the Icona cohort

2019

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 antiretroviral therapy (ART)-naïve and virologically suppressed treatment-experienced (TE) patients from the Icona (Italian Cohort Naïve Antiretrovirals) cohort who started, for the first time, a DTG-based regimen from January 2015 to December 2017. We estimated the cumulative risk of DTG discontinuation regardless of the reason and for toxicity, and of virologica…

Prevalence of acquired resistance mutations in a large cohort of perinatally infected HIV-1 patients

Rules-based HIV-1 genotypic resistance interpretation systems predict 8 week and 24 week virological antiretroviral treatment outcome and benefit fro…

2009

Objectives: To test retrospectively the ability of four freely available rules-based expert systems to predict short- and medium-term virological outcome following an antiretroviral treatment switch in pre-treated HIV-1 patients. Methods: The HIV-1 genotype interpretation systems (GISs) HIVdb, ANRS, Rega and AntiRetroScan were tested for their accuracy in predicting response to highly active antiretroviral therapy using 8 week (n = 765) and 24 week (n = 634) follow-up standardized treatment change episodes extracted from the Italian Antiretroviral Resistance Cohort Analysis (ARCA) database. A genotypic sensitivity score (GSS) was derived for each genotype-treatment pair for the different GI…

Chancre of the eyelid as manifestation of primary syphilis, and precocious chorioretinitis and uveitis in an HIV-infected patient: a case report

2012

Abstract Background Ocular syphilis is often difficult to diagnose because of the wide variation in clinical features. HIV co-infection may further complicate the picture. Case presentation Herein the authors report an unusual primary syphilitic ocular lesion in a 45-year-old Italian HIV-infected bisexual man who presented with a unilateral eyelid lesion. Associated precocious signs and symptoms in the posterior segment of both eyes, bilateral chorioretinitis and uveitis, are described. Intravenous penicillin and steroid treatment produced a rapid improvement in clinical status and complete resolution. Conclusions Careful questioning about sexual behavior is crucial for unmasking unusual fe…

ITPA deficiency and ribavirin level are still predictive of anaemia in HCV–HIV-coinfected patients receiving ribavirin combined with a first-generati…

2017

Background We aimed to determine the impact of inosine triphosphatase (ITPA) deficiency on ribavirin (RBV)-induced anaemia in HIV–HCV-coinfected patients receiving a triple therapy including the haematotoxic direct-acting antiviral agent boceprevir (BOC). Methods Patients of the ANRS HC27 BocepreVIH study were genotyped for two ITPA single nucleotide polymorphisms involved in ITPA deficiency. RBV trough concentration (Ctrough) was determined at week (W)4 and W8. Impact of ITPA deficiency on anaemia, RBV Ctrough, response and haematotoxicity (grade 3/4 anaemia, erythropoietin [EPO] use, RBV dose reduction or transfusion between day [D]0 and W8) was evaluated. Impact of RBV Ctrough on anaemia…

Time trends, characteristics, and evidence of scientific advances within the legal complaints for alleged sexual HIV transmission in Spain: 1996-2012.

2014

This article quantifies and characterizes existing legal complaints for the sexual transmission of HIV in Spain, describes temporal trends and whether advance of scientific knowledge is reflected in charging decisions, judicial reasoning, and sentences. Sentences and writs dictated by Spanish penal and civil jurisdictions between 1981 and 2012 were obtained through legal databases systematic search. Sixteen sentences and 9 writs belonging to 19 cases were included; 17 judged by penal and two by civil jurisdictions. The first sentence was pronounced in 1996, 3 between 1999 and 2000, 4 between 2001 and 2005, and 18 between 2006 and 2012. In 10 (53%) cases there was effective HIV transmission,…

Efficacy and safety of direct-acting antiviral regimens in HIV/HCV-co-infected patients – French ANRS CO13 HEPAVIH cohort

2017

International audience; Background & aims: There is little data available on the use of new oral direct-acting antiviral (DAA) regimens to treat human immunodeficiency virus and hepatitis C virus (HIV/HCV) co-infected patients in real-life settings. Here, the efficacy and safety of all-oral DAA-based regimens in HIV/HCV-co-infected patients enrolled in the French nationwide ANRS CO13 HEPAVIH observational cohort are reported.Methods: HIV/HCV-co-infected patients enrolled in the ANRS CO13 HEPAVIH observational cohort were included if they began an all-oral DAA-based regimen before 1st May 2015 (12-week regimens) or 1st February 2015 (24-week regimens). Treatment success (SVR12) was defined b…

Morphological analysis of the skeletal development in lateral cephalometric radiographs of HIV infected children ongoing Highly Active Antiretroviral…

2018

Background To investigate the skeletal development of HIV infected children through a morphological analysis of the cervical vertebrae (CV) in lateral cephalometric radiographs. Material and Methods The sample consisted of 86 lateral cephalometric radiographs of male and female children aged between 6 and 14 years old. The radiographs were equally distributed in groups 1 (HIV infected children) and 2 (non-infected children, paired by sex and age). Two examiners analyzed the CV according to the method of Hassel and Farman (1995). Spearman correlation coefficient was used to associate age and skeletal development within groups, while Mann-Whitney test compared the skeletal development between…

Pancreatic dysfunction and its association with fat malabsorption in HIV infected children

1998

Background—Nutrient malabsorption frequently occurs in HIV infected children, but very few studies have investigated exocrine pancreatic digestive capacity in these cases.Aims—To investigate pancreatic function in HIV infected children and to determine whether faecal fat loss, a prominent feature of intestinal dysfunction, is associated with pancreatic dysfunction.Patients—Forty seven children with HIV infection without apparent pancreatic disease and 45 sex and age matched healthy controls.Methods—Pancreatic function was evaluated by measuring elastase 1 concentration and chymotrypsin activity in stools by ELISA and colorimetric methods, respectively. Intestinal function was evaluated by m…

COVID-19 in people living with HIV: Clinical implications of dynamics of the immune response to SARS-CoV-2.

2020

ABSTRACT Background Little evidence on COVID‐19 in people living with HIV (PLWH) is currently available. Material and Methods We reported clinical and viro‐immunological data of all HIV‐positive patients admitted to our centre with COVID‐19 from March 1 to May 12,2020. Results Overall, five patients were included: all were virologically‐suppressed on antiretroviral therapy and CD4+ count was >350 cell/mm3 in all but two patients. Although all patients had evidence of pneumonia on admission, only one developed respiratory failure. SARS‐CoV‐2‐RNA was never detected from nasopharyngeal swabs in two patients, whereas, in the others, viral clearance occurred within a maximum of 43 days. IgG prod…
