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…

Nosocomial colonization due to imipenem-resistant Pseudomonas aeruginosa epidemiologically linked to breast milk feeding in a neonatal intensive care…

2008

Aim: We describe a one-year investigation of colonization by imipenemresistant, metallo-β-lactamase (MBL) producing Pseudomonas aeruginosa in a neonatal intensive care unit (NICU) of the University Hospital of Palermo, Italy. Methods: A prospective epidemiological investigation was conducted in the period 2003 January to 2004 January. Rectal swabs were collected twice a week from all neonates throughout their NICU stay. MBL production by imipenem-resistant strains of P aeruginosa was detected by phenotypic and molecular methods. Pulsed field gel electrophoresis (PFGE) was carried out on all isolates of P aeruginosa. The association between risk factors and colonization by imipenem-resistant…

UNIVERSAL VARICELLA VACCINATION IN THE SICILIAN PAEDIATRIC POPULATION: RAPID UPTAKE OF THE VACCINATION PROGRAMME AND MORBIDITY TRENDS OVER FIVE YEARS

2009

Following the licensure of the Oka/Merck varicella vaccine in Italy in January 2003, the Sicilian health authorities launched a universal vaccination programme in all nine Local Health Units. A two-cohort vaccination strategy was adopted to minimise the shift of the mean age of varicella occurrence to older age groups, with the goal of vaccinating with one dose at least 80% of children in their second year of life and 50% of susceptible adolescents in their 12th year of life. Two studies were implemented in parallel to closely monitor vaccination coverage as well as varicella incidence. Overall, the programme achieved its target, with 87.5% vaccine coverage for the birth cohort 2005 and 90.…

Brucellar aortitis and brucellar spondylitis

2015

Brucellosis is the most common bacterial zoonosis, and causes a considerable burden of disease in endemic countries. Cardiovascular involvement is the main cause of mortality due to infection with Brucella spp., and most commonly manifests as endocarditis, peripheral and cerebrovascular aneurysms, or arterial and venous thrombosis. We report a case of brucellosis presenting as bacteremia and aortic endarteritis 18 years after the last known exposure to risk factors for brucella infection. The patient was treated with doxycycline, rifampin, and gentamicin, and underwent surgical repair of a penetrating aortic ulcer, with a good clinical recovery. We review the signs and symptoms, diagnostic …

Heparin in COVID-19 patients is associated with reduced in-hospital mortality: the multicentre Italian CORIST Study

2021

Abstract Introduction A hypercoagulable condition was described in patients with coronavirus disease 2019 (COVID-19) and proposed as a possible pathogenic mechanism contributing to disease progression and lethality. Aim We evaluated if in-hospital administration of heparin improved survival in a large cohort of Italian COVID-19 patients. Methods In a retrospective observational study, 2,574 unselected patients hospitalized in 30 clinical centers in Italy from February 19, 2020 to June 5, 2020 with laboratory-confirmed severe acute respiratory syndrome coronavirus-2 infection were analyzed. The primary endpoint in a time-to event analysis was in-hospital death, comparing patients who receive…

A case of visceral leishmaniasis and pulmonary tuberculosis in a post-partum woman

2015

AbstractVisceral leishmaniasis due to Leishmania infantum is a vector-borne zoonotic disease transmitted by sand fly bites endemic in rural or periurban areas of the Mediterranean basin. Pregnancy is accompanied by changes in immune response, mainly a decrease in cellular immunity and a proportional increase in humoral immunity. These physiological events result in increased risk of infection by pathogens whose immunity is based on a T-helper 1 predominant response. We describe a case of visceral leishmaniasis and pulmonary tuberculosis diagnosed in a post-partum woman four days after delivery. The diagnosis of leishmaniasis should be considered in pregnant women with fever and haematologic…

Potential association of specific Candida parapsilosis genotypes, bloodstream infections and colonization of health workers' hands.

2014

AbstractFungal nosocomial infections continue to be a serious problem among hospitalized patients, decreasing quality of life and adding millions of euros to healthcare costs. The aim of this study was to describe the pattern of fungi associated with the hands of healthcare workers and to genotype Candida parapsilosis isolates in order to understand whether their high clinical prevalence stems from endemic nosocomial genotypes or from the real emergence of epidemiologically-unrelated strains. Approximately 39% (50/129) of healthcare workers were positive for yeasts and among 77 different fungal isolates recovered, C. parapsilosis was the most frequent (44/77; 57%). Twenty-seven diverse geno…

Rare AU-1-like G3P[9] human rotaviruses with a Kun-like NSP4 gene in children with diarrhea in Italy

2007

ABSTRACT Three G3P[9] rotaviruses, detected in children hospitalized with gastroenteritis in Palermo, Italy, were found to be genetically related to strains of either human or feline origin in the VP7, VP4, and VP6 genes. In contrast, in the NSP4 gene the viruses resembled G2P[4] human strains, suggesting a reassortment between AU-1-like and Kun-like strains.

Antimicrobial consumption and antimicrobial resistance: A snapshot of an Italian neuromuscular rehabilitation center

2017

The paper presents a snapshot of the incidence of antimicrobial-resistant microorganisms and antimicrobial consumption in an Italian rehabilitation center over a two-year period (2014-2015). Data on microorganism identification and antimicrobial susceptibility testing were obtained from the diagnostic laboratory of the hospital. A set of indicators was assessed, including the incidence density of resistant isolates per 1000 patient-days (IDRI). Data on antimicrobial consumption, semi-annually, obtained from the hospital pharmacy, were expressed as Defined Daily Dose (DDD) per 1000 patient-days. The most frequently isolated microorganism was Klebsiella pneumoniae (19.3%), and a significant i…
