Filter by:Hospital-acquired infections (HAIs) are significant public health issues, especially in low- and middle-income countries (LMICs). Hand hygiene and low-level disinfection of equipment (LLDE) practices among healthcare workers (HCWs) are essential to reduce HAIs. Various effective infection prevention and control (IPC) interventions to reduce HAI incidence have been developed. However, which interventions work effectively in LMICs has not been identified. The investigators aim to develop, pilot, and assess the feasibility and acceptability of an IPC intervention in Cambodia and the Lao People's Democratic Republic (PDR).
The aim of the study is to determine the efficacy of individualised homeopathic drug treatment (potency C200 and C1000) compared to placebo in females (age 18<65) with recurrent urinary tract infections, per definition ≥ 2 UTI in 6 months and/ or ≥ 3 UTI in 9 months.
Cefiderocol is a new antibiotic from the siderophore cephalosporin family for which there are few real-life data on its use in the treatment of infections with multidrug-resistant Gram-negative bacilli. The circulation of bacterial strains multi-resistant to antibiotics is important at the Strasbourg University Hospital, so the investigators wish to report their local experience of the 1st uses of Cefiderocol in the treatment of infections with multi-resistant Gram-negative bacilli to antibiotics in order to better clarify the use of this antibiotic (therapeutic indication, method of administration)
Type I interferons (IFN-I) production is induced by the detection of viral molecules, such as RNA or DNA viral strands, through pattern recognition receptors (PRR) present on many immune cell types. Despite a minimal concentration, IFN-I secretion activate the secretion, by neighbouring cells, of more than 700 proteins with antiviral properties (inhibition of viral replication, destabilization of virus membranes, etc.). IFN-I constitute therefore one of the major first line of defence established by the immune system in response to viral infection. Briefly, during the Coronavirus disease (COVID-19) pandemic, several teams including ours, highlighted a lack of IFN-I response in approximately one in five individuals presenting a severe form of COVID-19. Interestingly, within a large part of them, in vitro investigations revealed the presence of autoantibodies presenting neutralizing capacities against alpha and/or omega interferons This finding confirms the deleterious role of anti-IFN-I autoantibodies on the antiviral immune response and the key role of IFN-I pathway regarding defences against COVID-19 infection. Furthermore, those observations pave the way to interesting research that would allow understanding the underlying pathophysiological mechanisms of severe viral respiratory infection. The research hypothesis are: i) IFN-I deficiency could induce severe forms of viral infections which could lead to intensive care admission ii) IFN-I deficiency could increase viral loads in nasopharyngeal samples, and be associated with protracted viral clearance iii) The frequency of viral co-infections may be higher in case of IFN-I antiviral pathway blockade, iv) severe forms of respiratory viruses' infections could be induced by other anti-cytokine autoantibodies. In addition to confirming research hypotheses recently mentioned, the aim of this clinical protocol will be to assess the impact of antiviral innate immune response alterations in severe respiratory infections.
Human Immunodeficiency Virus (HIV), hepatitis C (HCV), and syphilis are sexually transmitted and blood borne infections (STBBI) that affect millions of people worldwide and rates are rising in Canada. HCV and syphilis are curable, and HIV is treatable with virtually no risk of transmission to sexual partners when the infection is controlled, however, these outcomes require adequate testing. Unfortunately, an estimated 44% of Canadians living with HCV and 13% living with HIV are not diagnosed. These undiagnosed cases are the source of over half of new HIV infections. Furthermore, HIV-syphilis coinfection is common. Accessible testing forms a key pillar of an elimination strategy and acts as an access point for linking people to care. Community pharmacies are more accessible site for STBBI testing, compared to hospitals and doctors' offices. This is especially true for members of marginalized communities, some of whom are at higher risk of infection. The COVID-19 pandemic highlighted the need for low-barrier STBBI testing, as in-person healthcare services at doctors' offices and traditional screening clinics were scaled back. Pharmacies remained open throughout the pandemic. The APPROACH 2.0 study will assess the impact of a pharmacy-based testing program for HIV, hepatitis C, and syphilis in participating pharmacies in three Canadian provinces: Newfoundland & Labrador, Alberta, and Nova Scotia on finding new diagnoses and linkages with care. Participants will be offered point of care tests for HIV and/or HCV and/or a dry blood spot test which will test for HIV, HCV, and syphilis. These tests are easy to administer. Results from the point of care tests are available immediately during the pharmacy visit while participants will be contacted with dried blood spot test results when available (approximately 2 weeks). Participants with reactive tests are linked with confirmatory testing and care, and those with non-reactive results are offered preventative services including HIV PrEP (as indicated) and counselling. This study builds on a pilot study completed in 2017 (www.APPROACHstudy.ca).
Liver transplantation is the only curative treatment of end-stage liver disease, and every year, around 60 patients undergo liver transplantation in Denmark. Immunosuppressive therapy is necessary to avoid rejection of the transplanted organ. Over 90% of adults have been infected with at least one herpesvirus, and it is characteristic for herpesviruses that after a first-time infection, the virus remains dormant in the body and may reactivate, particularly if the host is immunosuppressed. An effective immune response against reactivation depends highly on T cells, but T cells are suppressed by immunosuppressive drugs given to organ transplant recipients. Infections caused by herpesviruses are therefore very common in organ transplant recipients, and particularly two herpesviruses, cytomegalovirus (CMV) and varicella-zoster virus (VZV) pose challenges after transplantation. CMV causes significant morbidity in transplant recipients, contributes to increased mortality and may contribute to loss of the transplanted organ. CMV infections occur in around 40% of liver transplant recipients within a year of transplantation. VZV causes chickenpox at first-time infection and shingles at reactivation. VZV is the second-most common infection in transplant recipients and occurs in around 9% of liver transplant recipients each year. Organ transplant recipients are at higher risk for disseminated disease with complications compared to immunocompetent persons. A limited number of drugs exist that reduce the risk of and treat CMV infection, but they may cause significant adverse events, and drug resistance is emerging. To avoid CMV infection, some liver transplant recipients receive prophylactic therapy, but due to toxicity, new treatment modalities are warranted. This requires knowledge about herpesvirus specific T cell function in liver transplant recipients, which currently is limited. The aim of this study is to provide an in-depth description of the protective immune response and immunological risk factors for CMV and VZV infections in liver transplant recipients and to identify patients at high risk in order to provide a platform for future treatment modalities against CMV and VZV infections in liver transplant recipients.
The purpose of this study was to evaluate the effect of Helicobacter pylori infection on the quality of gastric mucosa preparation.
Study to evaluate the safety, tolerability and antiretroviral activity of a new therapeutic strategy, based on the administration of dasatinib, an ITK, in patients with recent (3-12 months) asymptomatic HIV-1 infection.
Randomized clinical trial to evaluate the effect of two probiotic strains which belong to Bifidobacterium Longum and Pediococcus pentosaceus species on fecal microbiota composition in healthy infants. Secondary outcomes comprise evaluation of anthropometric growth, digestive tolerance, sleeping habits, incidence of functional gastrointestinal disorders, incidence of gastrointestinal and respiratory infections, allergic reactions and safety and tolerability of the product.
