Active clinical trials for "Communicable Diseases"

To assess the molecular epidemiology, clinical impact, treatment outcome and risk factors for infections caused by Enterobacteriaceae producing ESBLs in Italy in a large multicenter observational survey. SPECIFIC OBJECTIVES To collect consecutive nonreplicate isolates of Enterobacteriaceae resistant to expanded-spectrum cephalosporins from clinical specimens from inpatients and outpatients. To characterize the isolates for resistance phenotypes and for β-lactam resistance mechanisms. To investigate the clonality of isolates. To analyse the epidemiology of various resistance mechanisms/resistant clones. To collect clinical and epidemiological data for patients with infections caused by the ESBL producers. To analyse the epidemiology, risk factors and outcome for infections caused by ESBL producers.

We hypothesized that pretreatment nonresponder and responder liver tissue would show consistent differences in gene expression levels and that these differences could be used to predict treatment outcomes and this can obviate the need of the present therapeutic trial.We are interested in conducting a retrospective study using the data of patients suffering from chronic HCV infection who were treated in our department with a combination of PEGINTERFERON and RIBAVIRIN. All these patients underwent liver biopsy prior the treatment. Based on the clinical data available it is possible to determine the responders and nonresponders to this therapy.RNA will be extracted from the liver tissue and the expression of 5 genes(IFI15,IFI616,IFI1,OAS3,OAS2 )will be checked .The prediction power of the combination of these genes in differentiating responders from nonresponders will be determined.

Cystography is a frequent pediatric examination, although indications have been recently restricted . Current indications in our center are: The occurrence of 2 episodes of acute pyelonephritis or 1 episode of pyelonephritis if dilatation of the pelvic ureter> 5 mm for male children Urinary tract infections that occurred in the month following this test are considered secondary to cystography. However, no recent study has investigated the prevalence of urinary tract infections post cystography. There is no recent epidemiological data on this risk of infection, especially since the management of infections has changed and aseptic precautions during retrograde cystography have evolved with most of the time coverage. antibiotic. The main objective of this multi-center epidemiological prospective study is to perform a recent analysis of the retrograde post-cystographic urinary tract infection rate. Material and methods: Epidemiological, observational, multicenter, prospective study over a period from January 2018 to January 2019. No therapeutic modification will be undertaken at the end of the study. Parents will be called one months after the exam to check if their child had a urinary infection.

It is widely known that vitamin D has an important role in calcium metabolism and bone mineralization. Its deficiency is related to rickets and osteomalacia in children and adults respectively. Vitamin D had a role in innate and acquired immunity. It increases innate defense and modulates lymphocytes activation, leading to a change toward a T2 helper response ). The role of vitamin D deficiency on the risk of bacterial infection among patients in intensive care units has been reported. An observational studies in children reported an association between low 25-OH vitamin D level and infectious viral diseases . The deranged metabolism of vitamin D in liver cirrhosis was first reported in the late '70s and was attributed mainly to impaired 25(OH)-vitamin D hydroxylation of the precursor vitamin D caused by impaired liver function. Low level of vitamin D was found independently to be associated with increased risk of bacterial infections in patients with liver cirrhosis. The observed relationship between the lack of vitamin D and the increase risk of mortality in cirrhotic patients could be attributed to bacterial infections. Thus, the association of low vitamin D levels with liver insufficiency and infections supports the use of vitamin D as a prognostic marker in the population of cirrhosis. Studies on the role of vitamin D as a risk factor for infections in patients with liver cirrhosis are not well studied in our locality(Upper Egypt).

This study evaluate Microbial growth on Bre-Flex versus PEEK denture base in Bilateral Maxillary bounded partial denture , half of patients will receive a framework with breflex denture base and the other half will receive a framework with PEEK denture base then evaluate the Candida growth

The REspiratory Syncytial virus Consortium in EUrope (RESCEU) is an Innovative Medicine Initiative (IMI) effort funded by the EU under the H2020 framework to define and understand the burden of disease caused by human respiratory syncytial virus (RSV) infection. RSV causes severe disease in individuals at the extremes of the age spectrum and in high risk groups. It was estimated that RSV was associated with 34 million cases of acute respiratory tract infection (ARTI), 3.4 million ARTI hospitalizations and 55,000 to 199,000 deaths in children <5 years in 2005 worldwide. These estimates were based on limited data and there is a substantial gap in knowledge on morbidity and associated healthcare and social costs in Europe. New vaccines and therapeutics against RSV are in development and will soon be available on the European market. RESCEU will deliver knowledge of the incidence and burden of disease RSV in young children and older adults in Europe, which is essential for stakeholders (governments, etc) to take decisions about prophylaxis and treatment. Objective: To determine the burden of disease due to RSV in young children. Study design: Prospective epidemiological, observational, multi-country, multicenter cohort study. Study population: Birth cohort of healthy infants (follow-up from birth until the age of 3 years maximum): Passive birth cohort (n=9,000). Active birth cohort (n=1,000). Main study parameters/endpoints: The primary endpoint of the study is the incidence of RSV infection-associated ARTI, RSV associated medically attended (MA) ARTI (active birth cohort) and RSV related hospitalization (passive birth cohort) in infants (< 1 year) during 3 RSV seasons. In addition, a major secondary endpoint is RSV attributable burden of wheezing.

The term of End Stage of Liver Disease (ESLD) was raised in 80's of 20 Century, but without a restrict definition. Infections are the cause and effect in occurrence and development of ESLD, which not only induce or exacerbate ESLD, but also are the most combined complication. Multi-resistant bacteria, multi-organ injury, selection of anti-microbes, supporting treatment, disorder of intestine microbiota, et al are dilemma in clinical practice. Appropriate and formal diagnosis and treatment of ESLD combined infection are imperious nowadays.

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.

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.

Dialysis patients have a higher risk of infectious complications including complications from the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which causes COVID-19. There have been several reports describing the effect of CO¬VID-19 in the dialysis population.
