Filter by:Exacerbations, in particular during chronic Pseudomonas aeruginosa (PA) infection, are very important in the prognosis of patients with non-cystic fibrosis bronchiectasis (BE). In Cystic Fibrosis patients, PA biofilms are associated with chronic respiratory infections and are the primary cause of their increased morbidity and mortality. However, the presence and role in exacerbations of PA biofilms, microbiome dysbiosis and inflammatory biomarkers has not been studied in depth in BE patients. Our aim is to determine the association between PA chronic infection and its biofilms with the number of exacerbations in the next year (primary outcome), time until next exacerbation, quality of life, FEV1 and inflammatory biomarkers (secondary outcomes) in BE patients with or without chronic obstructive pulmonary disease (COPD). The investigators will include and follow up during 12 months post study inclusion, 48 patients with BE and 48 with BE-COPD, with a positive sputum culture of PA. During stability and follow up (and in each exacerbation) The investigators will collect 4 sputum, 4 serum samples, perform spirometry, and quality of life tests every three months. For the biomarkers subproject, 4 additional serum samples will be collected at: exacerbation, 3-5 days after treatment, at 30 days and three months post-exacerbation. Biomarkers will be measured by commercial kits and Luminex. The investigators will quantify PA colony forming units (CFU)/mL, their resistance pattern, their mutation frequency and isolate mucoid and non-mucoid colonies. In each sputum, the investigators will analyze by Confocal Laser Scanning Microscopy (CLSM) and Fluorescent in situ Hybridizatrion (FISH) PA biofilms, their size, bacterial density and their in situ growth rate. Specific serum antibodies against PA will be determined through Crossed Immunoelectrophoresis. In addition, the investigators will indentify potential respiratory microbiome and gene expression patterns predictive for exacerbations, or with a protective role against chronic PA infection, as well as their association with biofilms. Microbiome analysis will be performed through the Illumina Miseq platform. Finally, the investigators will explore the antimicrobial activity of novel combinations of antibiotics against PA, both in in vitro planktonic cultures and in a biofilm model, and will include testing of antibiotic-containing alginate nanoparticles.
Solid-organ transplant patients are at increased risk of infectious diseases. Among this population, infectious diseases may be life-threatening or lead to graft rejection. Their prevention is an important challenge. Despite specific national recommendations, vaccination is underutilized. That is why we propose a dedicated infectious diseases consultation during pre-kidney transplantation assessment.
The primary objective of this study is to evaluate the efficacy of the drug nitazoxanide 500 mg, administered three times a day, in relation to placebo in preventing the development of COVID-19 in household contacts of patients diagnosed with the disease.
To assess if TSLP expression by airway epithelial cells following COVID-19 infection regulates viral load and disease severity.
This is an open-label, multicentre, randomized, parallel group study to evaluate the efficacy of treatment with oxygen-ozone therapy plus oral antibiotic therapy, in comparison with oral antibiotic therapy alone, in the proportion of patients with resolution/improvement of signs and symptoms of infection of the wound (e.g. ulcer, eschar, sore) in the target lesion after 14 days of treatment, in patients with infections secondary to implant of orthopaedic devices.
A randomized, single blind, parallel controlled, multicenter clinical study was performed in which patients who had undergone a cerebrospinal fluid to peritoneal shunt that met the criteria were divided into two groups (test and control) in a 1:1 ratio, with the test group applied disinfection by the "three-step sterilization method" and completed the procedure, and the control group underwent the same surgical procedure according to the routine aseptic disinfection procedure, relevant literatures were reviewed and the previous ones in our hospital were summarized, it is intended to conduct a one-year clinical observation of the two groups, to compare the perioperative and long-term infection incidence of the two groups and evaluate them comprehensively, to evaluate whether the "three-step sterilization method" disinfected patients have reduced perioperative and long term infection risk after surgery compared with previous surgery with routine disinfection procedure, and to evaluate their effectiveness.
188 healthcare personnel from 20 residential care homes (RCHs) will be recruited to assess the effect of 2-week implementation of Blended Gaming COVID-19 Training System (BGCTS) on RCH staffs' infection control practices. These clusters (RCHs) will be randomly allocated to two study groups (the intervention group, IG; and the control group, CG) to assess 1. whether more staff in the IG perform infection control practices (by on-site observations) than the staff in the CG after receiving BGCTS and 2. whether more staff in the IG have infection control knowledge, positive attitudes towards infection control, and self-reported compliance rates than the staff in the CG. 5 Hypothesis have been set up for this study: H1. After using BGCTS, a higher proportion of the staff in the IG will exhibit performance in complying with hand hygiene measures than those in the CG. H2. After using BGCTS, a higher proportion of the staff in the IG will exhibit performance in complying with other infection control practices than those in the CG. H3. After using BGCTS, a higher proportion of the staff in the IG will have high level of knowledge of infection control than those in the CG. H4. After using BGCTS, a higher proportion of the staff in the IG will have positive attitudes towards infection control than those in the CG. H5. After using BGCTS, a higher proportion of the staff in the IG will have a high self-reported compliance rate with infection control measures than those in the CG. Infection control practices conducted by RCH staffs will be measured through unobtrusive on-site non-participatory observations. RCH staffs' knowledge, attitudes about infection control practice, and self-reported infection control practices will be assessed via an electronic quiz.
The main objective of this cohort is to characterize COVID-19 patients hospitalized in infectious disease department. The collection of clinical and biological data from start of hospitalization to long-term follow up will contribute to a better description of the patient care, to the identification of predisposition to complication related to the disease, and to the evaluation of the impact of different therapeutical strategies.
investigators will take stool and blood samples from two groups of humans :- 1-group A (healthy group negative Giardia or control group),2-group B (positive Giardia or case group)then investigators make estimation for vitamin D in both groups then investigators try to find if there is relation between vitamin D level and Giardia lamblia infections
Pathogen-free, concentrated, pooled convalescent plasma has higher SARS-CoV2 antibody titers and neutralizing antibody activities, without requiring blood group compatibility that allows patient accessibility in a shorter time and has safe plasma characteristic.
