Long peripheral catheters for intravenous infusions of iloprost or alprostadil therapy in rheumatologic outpatients.

Background: Long peripheral catheters (LPCs) role in Difficult IntraVenous Access (DIVA) patients admitted to the emergency department has already been studied, resulting in a rapid, safe, and cost-effective procedure. Although their use in outpatient settings is established, there is a lack of studies assessing their benefits. In particular, rheumatologic outpatients affected by scleroderma, especially those affected by digital ulcers, are often treated with intravenous infusions of prostaglandin I (PGI) analog (IV-PGIA).

Integrated short peripheral intravenous cannulas and risk of catheter failure: A systematic review and meta-analysis.

Background: Short peripheral catheters (SPCs) are used to provide intravenous therapies in hospitalized patients. Recently, the category of SPC has become more complex, with the introduction in clinical practice of "integrated" SPCs (ISPCs), renewed regarding the material (polyurethane rather than polytetrafluoroethylene) and design (large wing; pre-assembled extension; preassembled needle-free connector (NFC)).

Methods: This systematic review and meta-analysis aimed to analyze randomized controlled trials (RCTs) and quasi-randomized studies in hospitalized patients, analyzing the risk of overall catheter failure as well as the risk of each type of complication (occlusion, infiltration, thrombophlebitis, and dislodgement) for ISPCs compared to non-integrated SPCs.

Disinfectant caps effectiveness.

Background: Catheter-related bloodstream infections (CRBSIs) are a major cause of morbidity and mortality among hospitalized patients. Different studies suggest that the use of disinfectant caps (DCs) significantly reduces the rate of CRBSIs. The first purpose of this study is to analyze, through an -model, the antiseptic effect of DCs produced by two manufacturers; the second aim is to assess potential differences in terms of effectiveness between the two manufacturers' products.

Physicochemical Characteristics of Antimicrobials and Practical Recommendations for Intravenous Administration: A Systematic Review.

Most antimicrobial drugs need an intravenous (IV) administration to achieve maximum efficacy against target pathogens. IV administration is related to complications, such as tissue infiltration and thrombo-phlebitis. This systematic review aims to provide practical recommendations about diluent, pH, osmolarity, dosage, infusion rate, vesicant properties, and phlebitis rate of the most commonly used antimicrobial drugs evaluated in randomized controlled studies (RCT) till 31 March 2023.

Safety of mid-thigh exit site venous catheters in multidrug resistant colonized patients.

Introduction: Venous catheters inserted in superficial femoral vein and with mid-thigh exit site have emerged as a feasible and safe technique for central or peripheral tip's venous access, especially in agitated, delirious patients. The spread of multidrug-resistant bacterial (MDR) strains is an emerging clinical problem and more and more patients are being colonized by these types of bacteria. The aim of this study is to evaluate the incidence of central line associated bloodstream infections (CLABSI) or catheter related bloodstream infections (CRBSI) in mid-thigh catheters in patients with positive rectal swabs to evaluate the safety of this procedure and the real infection risk.

A decision-making algorithm proposal for PICCs and midlines insertion in patients with advanced kidney disease: A pilot study.

Introduction: Kidney Disease Outcomes Quality Initiative clinical practice guidelines recommend avoiding placement of peripherally inserted vascular access devices in patients with an estimated glomerular filtration rate (eGFR) <45 ml/min. On the other hand, many patients with severe chronic kidney disease (CKD) have poor prognosis.This study carried out a global assessment of mortality at 2 years through Charlson Comorbidity Index (CCI) and Beclap score in patients with PICCs or Midlines, assuming that in those with an estimated high mortality rate at 2 years, it could be acceptable to implant a peripheral vascular access device (PVAD) despite the presence of CKD.

Midline peripheral catheters inserted in the superficial femoral vein at mid-thigh: Wise choice in COVID-19 acute hypoxemic respiratory failure patients with helmet continuous positive airway pressure.

Background: During coronavirus disease 2019 (COVID-19) pandemic, Helmet Continuous Positive Airway Pressure (h-CPAP) has been widely used to treat Acute Hypoxemic Respiratory Failure (AHRF). In COVID-19 patients undergoing h-CPAP a simple short peripheral catheter could be insufficient. According to the European Recommendations for Proper Indication and Use of Peripheral venous access consensus, a stable peripheral Vascular Access Device is indicated for intravenous treatment compatible with the peripheral route scheduled for more than 1 week.

Role of serum albumin and proteinuria in patients with SARS-CoV-2 pneumonia.

Background: Hypoalbuminemia is frequently observed in patients with SARS-CoV-2 infection although its underlying mechanism and relationship with the clinical outcome still need to be clarified.

Methods: We retrospectively evaluated in patients with COVID-19 hospitalised at the Fatebenefratelli-Sacco Hospital in Milan, the prevalence of hypoalbuminemia, its association with the severity of COVID-19, with the levels of C-reactive protein, d-dimer and interleukin-6 and with clinical outcome over a follow-up period of 30 days. Urinalysis was evaluated in a subgroup of patients.

A case of extremely prolonged viral shedding: Could cell cultures be a diagnostic tool to drive COVID-19 patient discharge?

This study addressed the case of a patient with prolonged COVID-19 viral shedding, reported by Real-Time PCR, until 71 days from symptom onset. However, viral culture received negative results after 30 days from symptom onset. Therefore, viral culture may be a worthwhile test for patients requiring discharge, in particular for those presenting prolonged viral shedding.

Off-label use of tocilizumab for the treatment of SARS-CoV-2 pneumonia in Milan, Italy.

Background: Tocilizumab, a humanized monoclonal antibody, targets IL-6 receptors blocking downstream pro-inflammatory effects of IL-6. In preliminary reports it was suggested to be beneficial in patients with severe COVID-19.

Methods: In this open-label prospective study we describe clinical characteristics and outcome of 51 patients hospitalized with confirmed and severe COVID-19 pneumonia treated with tocilizumab intravenously.

Impact of prolonged maraviroc treatment on non-AIDS-related comorbidities in HIV-positive patients: a retrospective cohort study.

Objectives: This retrospective study evaluates the effect of maraviroc, the first CCR5 receptor antagonist, on non-AIDS-related comorbidity incidence and its impact on inflammatory and lipid parameters.

Methods: Seventy-four HIV patients on maraviroc treatment were compared with 312 patients never exposed to maraviroc (matched for sex, age and CD4 nadir).

Results: At baseline (T0), maraviroc patients presented a longer duration of HIV infection, a higher prevalence of comorbidities and a greater frequency of polypharmacy.

Autoimmunity after liver transplantation: a frequent event but a rare clinical problem.

Autoantibodies are frequently detected after liver transplantation (LT), but their role is unclear. This study was designed to address three points: autoantibody prevalence pre-LT and over time up to five yr after LT, identification of possible predictors of autoantibody formation, and correlation between autoantibodies and graft dysfunction. To these aims, we retrospectively evaluated 92 consecutive LT recipients for whom prospectively stored frozen sera were available for autoantibodies assessment by immunofluorescence.

Prognostic factors of hepatic decompensation and hepatocellular carcinoma in patients with transfusion-acquired HCV infection.

Aims: Aim of this study was to assess if host (immunogenetic traits, age, sex), exogenous (alcohol) or viral factors (viral type, past HBV infection) might affect the progression of chronic hepatitis C to liver decompensation or the development of HCC in a cohort of patients exposed to a single blood transfusion prior to the introduction of anti-HCV screening.

Methods: Two hundred and forty-eight patients with a history of a single exposure to blood or blood products prior to 1990 were retrospectively considered. Patients were devoid of other risk factors of liver disease or immunosuppression and naïve to antiviral therapies.

Short communication: impact of hepatitis C viral clearance on CD4+ T-lymphocyte course in HIV/HCV-coinfected patients treated with pegylated interferon plus ribavirin.

The long-term impact of pegylated-interferon plus ribavirin (Peg-IFN-RBV) treatment outcome on CD4 T cell course in patients coinfected with human immunodeficiency virus (HIV) and hepatitis C virus (HCV) is unknown. The aim of this study was to investigate the impact of HCV-RNA clearance by standard anti-HCV therapy on long-term CD4 cells recovery in HIV/HCV patients on successful combined antiretroviral therapy (cART). We retrospectively enrolled HIV/HCV-coinfected patients on stable cART, treated with Peg-IFN-RBV between 2005 and 2009.

Liver-related factors associated with low vitamin D levels in HIV and HIV/HCV coinfected patients and comparison to general population.

Objectives: Low 25-Hydroxyvitamin D (25[OH]D) was associated with severe fibrosis and low sustained virological response (SVR) after interferon (IFN)-based therapy in chronic hepatitis C. Furthermore, hypovitaminosis D was reported in HIV-infected individuals, but its role in liver disease progression in HIV/HCV coinfection is unknown.

Methods: 25(OH)D was retrospectively measured in 237 HIV-infected patients (93 with HCV coinfection) and 76 healthy controls.

Human parvovirus 4 in the bone marrow of Italian patients with AIDS.

Human parvovirus 4 (PARV4) is a recently discovered member of the Parvoviridae. We investigated the presence of this virus in bone-marrow aspirates of 35 Italian patients with AIDS. Viral DNA was detected by polymerase chain reaction in over 40% of patients (16/35).

Clinical use of polymerase chain reaction performed on peripheral blood and bone marrow samples for the diagnosis and monitoring of visceral leishmaniasis in HIV-infected and HIV-uninfected patients: a single-center, 8-year experience in Italy and review of the literature.

Background: To overcome some of the limitations of conventional microbiologic techniques, polymerase chain reaction (PCR)-based assays are proposed as useful tools for the diagnosis of visceral leishmaniasis.

Patients And Methods: A comparative study using conventional microbiologic techniques (i.e.
