Implementation of infection prevention and control components in Italian hospitals based on a nationwide survey on behalf of INSIEME project

We aim to assess the state-of-the-art of Infection Prevention and Control (IPC) practices and their results in Italian healthcare facilities 6 years after the kick-off of the new National Plan for the Control of Antibiotic Resistance (PNCAR). This was a multicenter, cross-sectional, observational study conducted between January 1st, and December 31st, 2023, among Italian hospitals. Survey questions were readapted from the WHO IPC assessment framework (IPCAF), PNCAR and INSIEME group proposals, resulting in 155 questions grouped into six sections: IPC program, surveillance, control activities for healthcare-associated infections, antimicrobial stewardship (AMS) strategies, IPC training and education, and monitoring indicators. Thirty-eight acute care Hospitals completed the survey (response rate: 30%): 26.3% of hospitals did not define an annual program and 34.2% an AMS task force. Periodic microbiology reports were available for 57.9%, hospital alcohol-based hand rubs consumption per 1000 bed-days in 42.1% and defined daily dose of antimicrobials per 100 bed-days in 55.3% hospitals with a significant difference between Northern and Southern regions (90.9% vs 22.2%; P = 0.006). Active monitoring of hand hygiene and contact isolation compliance was implemented in only half of the hospitals. Structured HAI surveillance systems were implemented in fewer than 20% of hospitals. Components on IPC implementation activity, such as no-touch sanitizing systems, checklist for environmental cleaning, informatic flags, bundles for pathogens revealed the lowest score. The appropriateness of antibiotic therapy prescribing was assessed in 73.7% of facilities. Only 42.1% of hospitals had budget goals. This survey provides a baseline assessment and identifies key barriers to the implementation of IPC programs across Italian acute care hospitals. The findings highlight priority areas for intervention and will inform the next phase of the INSIEME project, which aims to develop and implement tailored strategies that address the specific needs of healthcare workers and institutions nationwide

Cystic lymphoepithelial lesions of the parotid gland in HIV-1 infection

The benign cystic lymphoepithelial lesion (BLL) of the parotid gland is a rare disorder affecting HIV-1-infected patients. Here we describe the clinical and histopathological features of 10 cases of BLL, who presented to our observation between November 1992 and December 1996, before the combination antiretroviral therapy was introduced

People living with undiagnosed HIV infection and a low CD4 count: Estimates from surveillance data, Italy, 2012 to 2014

Background and aims: Late HIV diagnosis is associated with onward HIV transmission, higher morbidity, mortality and healthcare costs. In Italy, more than half of people living with HIV were diagnosed late during the last decade, with a CD4 count < 350 cells/mm3 at diagnosis. We aimed to determine the number and characteristics of people living with undiagnosed HIV infection and low CD4 counts in Italy. Methods: Data on newly reported HIV diagnoses from 2012 \u20132014 were obtained from the national HIV surveillance system. We used the European Centre for Disease Prevention and Control HIV modelling tool to calculate the undiagnosed prevalence and yearly diagnosed fraction (YDF) in people with low CD4 count. Results: The estimated annual number undiagnosed HIV infections with low CD4 count was on average 6,028 (95% confidence interval (CI): 4,954\u20138,043) from 2012\u20132014. In 2014, most of the undiagnosed people with low CD4 count were men (82.8%), a third acquired HIV through sex between men (MSM) (35.0%), and heterosexual transmission (33.4%), respectively. The prevalence of undiagnosed HIV infection was 11.3 (95% CI: 9.3\u201314.9) per 100,000 residents ranging from 0.7 to 20.8 between Italian regions. Nationally the prevalence rate was 280.4 (95% CI: 173.3\u2013450.2) per 100,000 MSM, 8.3 (95% CI: 4.9\u201313.6) per 100,000 heterosexual men, and 3.0 (95% CI: 1.4\u20135.6) per 100,000 women. The YDF was highest among heterosexual women (27.1%; 95% CI: 16.9\u201345.2%). Conclusions: These findings highlight the importance of improving efforts to identify undiagnosed HIV infections primarily among men, both MSM and heterosexual men

Tocilizumab for patients with COVID-19 pneumonia. The single-arm TOCIVID-19 prospective trial

BackgroundTocilizumab blocks pro-inflammatory activity of interleukin-6 (IL-6), involved in pathogenesis of pneumonia the most frequent cause of death in COVID-19 patients.MethodsA multicenter, single-arm, hypothesis-driven trial was planned, according to a phase 2 design, to study the effect of tocilizumab on lethality rates at 14 and 30 days (co-primary endpoints, a priori expected rates being 20 and 35%, respectively). A further prospective cohort of patients, consecutively enrolled after the first cohort was accomplished, was used as a secondary validation dataset. The two cohorts were evaluated jointly in an exploratory multivariable logistic regression model to assess prognostic variables on survival.ResultsIn the primary intention-to-treat (ITT) phase 2 population, 180/301 (59.8%) subjects received tocilizumab, and 67 deaths were observed overall. Lethality rates were equal to 18.4% (97.5% CI: 13.6-24.0, P=0.52) and 22.4% (97.5% CI: 17.2-28.3, P&lt;0.001) at 14 and 30 days, respectively. Lethality rates were lower in the validation dataset, that included 920 patients. No signal of specific drug toxicity was reported. In the exploratory multivariable logistic regression analysis, older age and lower PaO2/FiO2 ratio negatively affected survival, while the concurrent use of steroids was associated with greater survival. A statistically significant interaction was found between tocilizumab and respiratory support, suggesting that tocilizumab might be more effective in patients not requiring mechanical respiratory support at baseline.ConclusionsTocilizumab reduced lethality rate at 30 days compared with null hypothesis, without significant toxicity. Possibly, this effect could be limited to patients not requiring mechanical respiratory support at baseline.Registration EudraCT (2020-001110-38); clinicaltrials.gov (NCT04317092)
