Filter by:Diagnosis of chronic prosthetic joint infection (PJI) can be difficult. 68Ga-citrate Positron Emission Tomography/Computed Tomography (PET/CT) has been recently developed and has many advantages such as high resolution and low radiation exposure. To date, 68Ga-citrate PET/CT has not been specifically assessed in prosthetic joint infection. In this prospective study, patients referred for a suspected PJI will benefit from both a 68Ga-citrate PET/CT and a 99mTc-HMPAO-labelled leukocyte SPECT/CT. The primary outcome is the assessment of the 68Ga-citrate PET/CT accuracy for the diagnosis of chronic prosthetic hip or knee infection.
CMV infection in transplantation remains the most frequent infectious complication causing increased morbidity and mortality. International recommendations advocate prevention of this infection by instituting direct antiviral treatment or monitoring viral replication by PCR with the start of curative antiviral treatment when the DNAemia is positive. The risk of CMV infection varies according to the serostatus of the donor (D) and recipient (R) at the time of transplantation. In the absence of prophylaxis, CMV infection occurs in 60-80% of D+R-, 50-60% of D+R+ and 25-50% of D-R+. The humoral anti-CMV response is represented by the production of antibodies to envelope proteins (gB and gH) and to molecules involved in viral attachment and entry into target cells. However, the majority of CMV-specific antibodies do not have antiviral neutralising activity. The investigators have identified a new player in the specific anti-CMV response expressing the Fc RIIIa receptor (CD16), that interacts with anti-CMV immunoglobulins (Ig): the Tgamma-delta V delta 2-negative lymphocyte (LTgdVd2neg). This lymphocyte subpopulation shows persistent expansion in the peripheral blood of kidney transplant patients with CMV infection. These cells express an effector-memory phenotype (CD45RA+/CD27-). This expansion is associated with resolution of infection in patients. The investigators have shown that CD16 is specifically and constitutively expressed on the surface of CMV-induced LTgdVd2neg in healthy volunteers and kidney transplant patients. The investigators have observed that one of the antiviral activities of anti-CMV IgG lies in its binding to the Fc RIIIa receptor (CD16) on the surface of LTgdVd2neg. The anti-CMV IgGs capturing virions thus activate CD16+ LTgdVd2neg with production of IFN interferon which in turn is responsible for inhibition of CMV viral multiplication. Anti-CMV IgG is a recommended therapeutic option, with a marketing authorisation for the prevention of CMV infection in kidney transplantation in Europe and a Temporary Authorisation for Use in France. Thus, R+ patients expressing a significant level of LTgdVd2neg CD16+ at D0 of transplantation could be protected against CMV, in the absence of direct antiviral treatment by the addition of anti-CMV Ig.
the aim of this study is to investigate the relationship between exposure to daptomycin and the occurrence of muscle toxicity or eosinophilic pneumonia in patients treated with daptomycin for bone and joint infection
To investigate PICUs in major cities in China by establishing a high-quality standardized clinical database of PICU inpatients Incidence, fatality rate, pathogen distribution, anti-infective treatment of community-acquired/nosocomial infections in inpatients.
Coverage Africa is a nested study in the large Anticov platform trial that aims to generate data on new early treatment strategies for mild/moderate COVID-19 patients in resource-limited-settings to reduce the number progressing to severe forms requiring hospitalization, thereby relieving the burden on health care systems and contributing to "flattening the curve" in contexts where none pharmaceutical intervention such as quarantine are difficult to implement in large urban settings. Treating early when the virus is still present might also limit transmission. Coverage Africa will be conducted in Guinea and Burkina Faso. The main objective is to conduct an open-label, multicenter, randomized, adaptive platform trial to test the safety and efficacy of several marketed products, including antiviral therapies versus control in mild/moderate of coronavirus disease 2019 (Covid-19) in resource-limited-settings. The study aims to recruit 600 patients in both countries, one site in Guinea and two sites in Burkina Faso. The current assessed treatments are now the association of Fluoxétine/Budésonide compared with a control arm: paracetamol. The adaptive design trial will allow for the removal of drugs, or the addition of new study arms when new data becomes available. Data on the primary efficacy parameters and safety will be integrated with the primary endpoint based on an oxygen saturation percentage (SpO2) ≤ 93% or death within 14 days after randomization to treatment, including death for any reason. Study will run until August 2022. However, with the proposed adaptive design, the study could also be interrupted for success earlier than planned with the identification of a treatment that significantly reduces hospitalization rate as evidence by results from the primary endpoint.
The value of cytobacteriological examination of urine (CBEU) before double J catheter removal has not been demonstrated. The aim of this study is to define the interest of this CBEU.
The study aims to evaluate whether organised, concomitant HPV vaccination and HPV screening offered to all resident women aged 22-27 will result in a more rapid elimination of HPV infection in Sweden. This objective will be examined at the population level.
The DepIST-H study, funded by the French AIDS and Hepatitis Research Agency (ANRS), is to estimate prevalence (the number of cases over a given period of time) and incidence (the number of new cases over a given period of time) of anal lesions (condylomas, dysplasia, cancers) by HIV status among MSM in Lomé, Togo
The investigators hypothesize that the use of a personal hand hygiene system (SafeHavenTM) by anesthesia providers in the adult operating room, combined with a novel infectious pathogen tracking system (OR PathTrac) will decrease participant exposure to pathologic bacteria in the adult operating room.
Patients requiring admission to the hospital due to a moderate and severe COVID-19 infection may differ in their ability to respond to viral infection and to eliminate viral load. Several comorbidities and interventions like antivirotic or antiinflammatory treatment may also modify expected patients response and decrease of viral load. In this observational study, evolution of selected inflammatory markers, indicators of severity of infection and patient characteristics will be followed and recorded in hospitalized patients with COVID-19.
