Filter by:The first person-to-person Coronavirus disease (COVID-19) transmission in Italy was reported on Feb 21st, 2020, causing one of the most massive outbreak in Europe so far that stopped immediately all elective surgical procedures. Bariatric surgery represents the most effective treatment to obtain an important, long-term weight loss and comorbidities' resolution, including respiratory disorders. A sensitive decrease of epidemic has been observed lately and a gradual and progressive stop of the lockdown (phase 2-3) was planned, when the virus is supposed to be under control and protocols are guiding the restart of the elective bariatric surgery. Several questions are currently open: Laparoscopic bariatric surgery is safe in the phase 2-3? What's the expected complications rate? The actual hospital protocols are effective to minimize the risk of postoperative COVID-19 infection? Aim: to analyse results of bariatric surgery during phase 2-3 COVID-19 pandemic in Italy. Primary end point: 30 days COVID-19 infection, mortality and complications. Secondary end points: readmission rate 30 days, reoperations for any reason related to surgery. Study design: prospective multicenter observational. Setting: Italian National Health Service 8 high-volume bariatric centres. Enrollment criteria: No previous Covid-19 infection; Primary, standard IFSO approved bariatric procedures; No concomitant procedure; No previous major abdominal surgery; >18<60 years old; Compensated comorbidities; Official SICOB's surgical informed consent given, including COVID-19 addendum; Adherence to very restrictive protocols regarding: hospital admission, management of in-hospital patients and after discharge. Follow-up: scheduled outpatient visit 30th postoperative day. Data evaluation: all the cases performed during July/December 2020 will be collected in a prospective database. Patients operated during the period July/December 2019 in the same centers will be considered comparative group (control). Expected results: Transparent information to the patients, and the introduction of the COVID-19 protocol concerning patients and health-professionals protection, should guarantee a safe restart of bariatric surgery in Italy. The network of 8 high-volume centers sharing information and protocols in this "unexplored" period will be a guarantee for patients' safety. Bariatric surgery should induce a postoperative amelioration of the comorbidities reducing the risks in case of a second outbreak.
Covid 19 is a pandemic infection developed in late 2019
The objective of this protocol is to estimate the proportion of patients hospitalized in intensive care unit for a SARS-Cov-2 viral lung infection and contaminating their environment at 1 meter. The contamination will be assessed by quantifying the viral RNA by RT-PCR on a 600-liter air sample aspirated by a Coriolis® system. This sample will be taken within 48 hours after the confirmation of SARS-Cov-2 infection, documented by RT-PCR. In fact, the hospital hygiene measures practiced in intensive care unit in patients with viral respiratory infection are identical to those practiced in other services. These measures are possibly insufficient as evidenced by recent data related to the COVID-19 epidemic.
The purpose of this research study is to learn more about the use of viral specific T-lymphocytes (VSTs) to prevent or treat viral infections that may happen after allogeneic stem cell transplant. Allogeneic means the stem cells come from another person. VSTs are cells specially designed to fight viral infections that may happen after a stem cell transplant (SCT). Stem cell transplant reduces the body's ability to fight infections. Viral infections are a common problem after transplant and can cause significant complications. Moreover, treatment of viral infections is expensive and time consuming, with families often administering prolonged treatments with intravenous anti-viral medications, or patients requiring prolonged admissions to the hospital. The medicines can also have side effects like damage to the kidneys or reduction in the blood counts, so in this study the investigators are trying to find a better way to treat these infections.
BK cytotoxic T cells (CTLs) manufactured with the Miltenyi CliniMACS Prodigy Cytokine Capture System will be safe and effective in decreasing specific viral load in children, adolescents and young adults (CAYA) with refractory BK infection post Allogeneic Hematopoietic Stem Cell Transplantation (AlloHSCT) or with primary immunodeficiencies (PID).
In summary, in this project the investigators propose to study the proviral DNA genotyping to implement a lower cost and wider than the commercial systems currently in use, in order to analyze all HIV genes that are therapeutic targets of antiretroviral drugs. Using HIV proviral DNA we can obtain information for: HIV-1 Viral Tropism, Mutations associated to Integrase Inhibitors, Mutations associated to Transcriptase reverse Inhibitors, Mutations associated to Protease Inhibitors, and Mutations associated to GP41 Inhibitors. Along with this the investigators propose to validate the proviral DNA as starting material for genotyping which is independent of the patient's viral load and achieve a greater number of patients living with HIV have access to this important test that is essential in monitoring the HIV infection. 3.2 RESEARCH QUESTIONs Is proviral DNA a genetic compartment suitable for carrying out a genotypic resistance test in patients with low or undetectable viral load? Does proviral DNA have the same clinical validity that RNA? 3.3.- HYPOTHESIS A resistance genotyping test carried out by Proviral DNA detects the same mutations associated to resistance that viral RNA. 3.4.- OBJECTIVES: General/Specific General objective Develop a methodology to assess the proviral HIV-1 DNA or RNA as the genetic material for genotyping assays in genes that are targets of pharmacological interest as TR reverse transcriptase and protease (PRO), Integrase or GP41 Inhibitors and HIV tropism. Specific Objectives 1. Carry out genotyping by proviral DNA and compare it with the same genes genotyping performed with viral RNA. 2. Once the correlation between proviral DNA and RNA has shown, standardize a method to use the technique for clinical use in monitoring HIV patients according to each patient's needs. RNA for patients with viral load above 1,000 copies/mL. Proviral DNA for patients with low or undetectable viral load.
The purpose of this study is to use VSTs (virus-specific T cells) from a donor that is a partial HLA (human leukocyte antigen) match with the patient to treat viral infections after an allogeneic hematopoietic stem cell transplant (HSCT). These cells may also have value in CAR-T recipients who have received a product that depletes virus specific T cells. The patient must have had a myeloablative or non-myeloablative allogeneic HSCT using either bone marrow, single/double umbilical cord blood, or peripheral blood stem cells (PBSC) or CAR T cell product targeting an antigen expressed on virus specific T cells. After a transplant, while the immune system grows back, the patient is at risk for infection. Some viruses can stay in the body for life and are normally controlled by a healthy immune system, but if the immune system is weakened, like after a transplant, they can cause life threatening infections. He/she must have had an infection with one or more of the following viruses -Epstein Barr virus (EBV), cytomegalovirus (CMV), adenovirus (AdV), Human polyomavirus type I (BKV), and human polyomavirus type II (JCV)- that has persisted or recurred despite standard therapy. In this study, the investigators want to use white blood cells that have been trained to treat viral infections. In an earlier study the investigators showed that treatment with such specially trained T cells has been successful when the cells are made from the transplant donor. However as it takes 1-2 months to make the cells, that approach is not practical for patients who already have an infection. In a subsequent study, the investigators were able to create multivirus-specific T cells (VSTs) from the blood of healthy donors and created a bank of these cells. The investigators then successfully used these banked cells to treat virus infections after a stem cell transplant. In this study the investigators have further modified their production method to decrease the potential side effects and the investigators want to find out if they can use these banked VSTs to fight infections caused by the viruses mentioned above.
This study aims to investigate the use of alpha-defensin as a diagnostic means to distinguish between acute bacterial and viral infections.
This Phase I-II dose-finding trial to determine the optimal dose of intravenous (IV) injection dose of donor-derived cytotoxic T lymphocytes (CTLs) specific for CMV, EBV, BKV and Adenovirus. A maximum of 36 patients will be treated in up to 18 cohorts each of size 2, with the first cohort treated at the lowest dose level 1, all successive doses chosen by the EffTox method, and no untried dose level skipped when escalating. The scientific goal of the trial is to determine an optimal IV-CTL cell dose level among the three doses 1.0x107cells/m2, 2 x107cells/m2 and 5x107cells/m2., hereafter dose levels 1, 2, 3. Dose-finding will be done using the sequentially adaptive EffTox trade-off-based design of Thall et al.
The purpose of this study is to demonstrate that viral specific T-cells (a type of white blood cell) can be generated from an unrelated donor and given safely to patients with viral infections.
