Active clinical trials for "Infections"

There is a recent increase in incidence of surgical site infection after cardiac surgery in our hospital, in spite of specific measures taken concerning some aspects of the surgical procedures, targeting a better control of the classically known major risk factors of infections, in routine procedures involving a sternotomy such as coronary artery bypass graft, valvuloplasty, aortic surgery, or combined procedures. The first objective of this monocentric prospective cohort study, is to evaluate underestimated specific risk factors of surgical site infection, during the perioperative period, for patients undergoing cardiac surgery with sternotomy. Secondly, to estimate the specific risk associated with each class or micro-organisms responsible, and their profile of resistance. The outcomes concern the occurrence of a surgical site infection diagnosed by the surgeon in charge of the patient, one month and three months after surgery; it may concern the pre operative period, the procedure itself, or the early post operative period, characterized by a high density of cares, or even the late rehabilitation, after discharge of the surgical unit. Secondary outcome evaluate the profile of agents identified regarding the susceptibility of the prophylaxis recommended to prevent wound infection; it may suggest that an adequate antibiotic prophylaxis is often insufficient to take into account the responsible agents, and that decolonisation is not always that helpful, in view of emerging cases of failure due to developing resistance. Considering the low incidence of that type of complication, the investigators estimated that a period of two years might be necessary to include a sufficient number of patient, at least one thousand, in order to find a dozen of factors that might be significantly associated with an increased risk of surgical site infection. The evaluation is permitted by the collaboration between the anesthesiologists, surgeons, intensivists, hygienists, all along the presence of the patient in the department, until discharge out of the hospital and after readmission eventually for infectious complication.

Myelodysplastic Syndromes (MDS) are characterized by quantitative and qualitative bone marrow failure and by a disorder of the medullary production which is a pre-leukemic state which can evolve into acute myeloid leukemia. The risk of leukemic transformation is estimated by the score IPSS (International Prognostic Score System). We distinguish the MDS of low risk (IPSS<1) and those of high risk of leukemic transformation (IPSS=1,5). Besides the risk of leukemic transformation, MDS much be complicated of infections which could be life-threatening. The risk of developing first infection after the diagnosis of MDS of high risk is probably influenced by anamnestic (disease duration, comorbidities), clinical (veinous central catheter, previous hospitalization), biological (neutropenia, lymphopenia, serum ferritin) and therapeutics (demethylating agent, lenalidomide, erythropoietin, G-CSF, transfusions, anti-infectious preventive treatment) factors. Their identification will allow for improved targeting of the population which is is likely to benefit from anti-infective prophylaxis Primary objective is to identify risk factors associated with first acute episode of infection in patients with MDS, by comparing index cases and matched control cases who did not develop infection episode since diagnosis. Secondary objectives are to explore nature and severity of infectious episodes, number of recurrences during 1 year of follow up and survival at 6 and 12 months

Helicobacter pylori is aspiral shaped gram negative organism that colonized the gastric mucosa.it was showen that intra familial infection play role in transmission of H pylori and mother play the key role in transmission .

Implant infections are among the most dramatic complications in orthopaedic surgery with heavy impact on life quality and health system. Their diagnosis is still challenging since, till now, none othe proposed markers has shown a sensitivity and a specificity of100%. Therefore, efforts in identification of new markers of infections are required. This study aims to evaluate the applicability of Interleukin (IL)-6, Triggering receptor expressed on myeloid cells (TREM-1), CC chemokine ligand 2 (CCL2), matrix metalloproteinases (MMP-9), osteopontin (OPN), IL-1 receptor antagonist (IL1-RA), IL-6 receptor beta (GP130), C5a, receptor for advanced glycation end products (sRAGE), urokinases and presepsin as serum markers of prosthetic joint infection. At this purpose, serum from 65 patients with infected implant and from 65 with aseptic failure of their prosthesis will be collected before surgery and after 2 and 7 days from revision.

Vaginal infection in early pregnancy is associated with an increased risk of spontaneous preterm delivery and late miscarriage. Most studies presume that vaginal infections are responsible for up to 40% of preterm birth. Although the causative microorganisms of vaginal infections are manifold, the three pathogens most commonly associated with vaginal infections are Gardnerella vaginalis, Candida albicans and Trichomonas vaginalis. The aim of this prospective study is the validation of the point-of-care tests OSOM BVBLUE for bacterial vaginosis and SavvyCheck Vaginal Yeast Test for candidosis in comparison to Gram stain.

A surgical site infection (SSI) is an infection that occurs after surgery in the part of the body

The primary objective in this study is to establish a list of host cellular proteins that mediate norovirus infection. Norovirus is one of the most common pathogens attributed to diarrheal diseases from unsafe food. It is also the primary cause of mortality among young children and adults in foodborne infections. Norovirus is not just a foodborne burden. In a recent meta-analysis, norovirus accounts for nearly one-fifth of all causes of (including person-to-person transmission) acute gastroenteritis in both sporadic and outbreak settings and affects all age groups. Undoubtedly, norovirus is of paramount public health concern in both developed and developing countries. Research efforts to better understand norovirus pathobiology will be necessary for targeted intervention. From Middle East respiratory syndrome coronavirus to Zika virus, efforts to identify host factors important for mediating virus infection has always been a research priority. Such information will shed light on potential therapeutic targets in antiviral intervention. Norovirus virus-host interaction studies have been hampered by the lack of a robust cell culture model in the past 20 years. In 2016, norovirus has finally been successfully cultivated in a stem cell-derived three-dimensional human gut-like structure called enteroid or mini-gut. In this study, intestinal stem cells will be isolated from duodenal biopsies collected from participants, followed by differentiation into mini-guts. Genome-wide genetic screening for host essential and restrictive factors will be performed on infected mini-guts by knockout CRISPR and gain-of-function CRISPR SAM, respectively. Shortlisted candidates will undergo preliminary functional validation in cell lines. These data will provide insights into potential therapeutic targets against norovirus infection.

Up to 1 in 5 women in Africa who deliver their baby by cesarean section get a wound infection. Surgical site infections (SSIs) are largely preventable, but they represent a considerable burden for health-care systems, particularly in low-income and middle-income countries. The prevention of these infections is complex and requires the integration of a range of preventive measures before, during, and after surgery. The aim of the proposed project is to determine the risk factors of Surgical Site Infection post-Cesarean Section in women admitted to Princess Christian Maternity Hospital (PCMH) in Freetown, Sierra Leone. Secondary aims are to determine the incidence of SSI and the predictors of a negative outcome in women with post-CS SSI.

Given the frequency and severity of invasive pneumococcal infections and questions about the place of VPC-13 in the prevention of pneumococcal infections in adults based on the presence of risk factors, current laboratory surveillance should be supplemented with data on the clinical features of adult invasive pneumococcal infections (IPI) cases. In particular it is necessary to collect for these cases, the clinical forms, the severity and the existence of risk factors and to make the link between these characteristics and those strains of pneumococci responsible for the IPI in particular, their serotype. The follow-up of the evolution of the cases according to the presence of risk factors, their clinical form and their serotype coverage (vaccine strain or not) must to guide recommendations for adult VPC-13 and to monitor the effects of VPC-13 vaccination recommendations. These effects are indirect, linked to the effect of vaccination of children with VPC-13 since 2010, which modifies the serotypes responsible for infections in vaccinated and unvaccinated patients, and the direct effects of possible use of the conjugate vaccine in adults (according to the recommendations that will be given by the Vaccination Technical Committee of the High Council of Public Health). The project is based on the existing network of 23 Regional Pneumococcal Observatories (ORP) located in metropolitan France and the network of infectious diseases by completing the microbiological collection of strains of pneumococci isolated from invasive infections in adults by a clinical collection in hospitals or voluntary clinics where the laboratory participates in the ORP. Given the establishment in 2012 of an adult bacterial meningitis observatory, to which the ORP are associated, this project does not include the surveillance of pneumococcal meningitis in adults.
