Filter by:This is a first in human clinical study to evaluate the safety, pharmacokinetics (PK), and pharmacodynamics (PD) of RQ-01. Adult patients who have tested positive for SARS-CoV-2 virus, have mild symptom(s) of COVID-19 disease, and who are at low risk for developing moderate or severe COVID-19 disease are welcome to participate. The main questions this study aims to answer are: 1. What is the safety profile of RQ-01? 2. What is the reduction in SARS-CoV-2 ribonucleic acid (RNA) shedding after administration of RQ-01? 3. How effective is RQ-01 versus placebo in reducing COVID-19 symptoms? After providing informed consent, subjects will be randomized to RQ-01 (high or low dose) or placebo and will be dosed for 3 consecutive days. Throughout the duration of the trial, subjects will participate in the following activities: perform rapid antigen and polymerase chain reaction (PCR) tests for COVID-19, answer questions about their medical history and medications, answer questions about their COVID-19 history and symptoms, conduct a physical exam, have their vitals measured, and have bloodwork done.
All patients who presented with epigastric pain and dyspeptic symptoms will undergo endoscopic gastric biopsies. The patients will be subjected to: Full history taking, clinical examination, liver function tests, renal function tests, CBC, INR, abdominal ultrasonography. About 200 patients diagnosed to have H. pylori by infection by microscopically examined, endoscopic gastric biopsies will be enrolled in our study. All available formalin fixed and paraffin embedded tissue blocks of gastric endoscopic biopsies will be resectioned and stained with Haematoxylin and Eosin. Modified Giemsa stain, and Alcian blue/ PAS stain will be used for verification of Helicobacter pylori and demonstration of intestinal metaplasia respectively. Biopsies will be classified using the Updated Sydney system of classification of gastritis
Rationale: Respiratory tract infections (RTI) are a major cause of morbidity in young children in high- income countries and the major cause of mortality in developing countries. Causative bacteria and viruses are regular residents of the nasopharynx of asymptomatic individuals (colonization) and live there together with other presumed harmless commensals, without causing disease. These non-pathological infections/colonization episodes are important for transmission, intermediate step to disease and boost immune responses. The investigators recently validated the use of minimally-invasive nasal sampling methods that can be done at home for the study of host and microbial parameters in adults and children. In this study the investigators will focus on the daily microbial and immunological composition of the nasopharynx during health in relation to symptoms. Primary objective: Associate acquisition of pneumococcal colonisation with levels of pre-existing polysaccharide specific memory B cells. Secondary objectives include: Validate the use of synthetic absorptive matrices (SAM) for detection of respiratory pathogens versus nasopharyngeal swabs (NPS) and saliva; Assess dynamics of URT infection/colonisation and examine its relationship with symptoms, host responses and microbiota; Measure transmission between children and parents and immune responses in parents. Study design: Prospective community-based cohort study.total of 45 children, aged 1-5 years old attending daycare or (pre-)school, will be included, including a pilot of 10 children to assess tolerability. If there are insufficient pneumococcal acquisitions in the study to assess the primary outcome, additional children can be recruited in groups of 3 or 4 children (up to 10). For a subset of participating children, both parents will be asked to self-collect daily saliva during the study. Primary study parameters: Frequency of systemic polysaccharide specific B cells in children that become colonised during the study versus children that do not become colonised Secondary study parameters: Dynamics of respiratory bacteria and viruses during URT infection/colonisation. Presence and load for bacteria and viruses in children in SAM versus saliva and NPS. Local microbiota and immune profiles and association with infection/colonisation and symptomology. For a subset of parents, daily presence and load of bacteria and viruses as well as host immune factors measured in saliva.
Kidney transplantation is the best method of renal replacement in patients with irreversible renal failure. One of the biggest problems today is premature loss of function of the transplanted kidney. This occurs most often on the basis of chronic humoral rejection. This is the immune response to the kidney, in which the specific antibodies play a crucial role (both against the HLA and the non-HLA system). The aim of this study is to analyze one of the situations where the production of antibodies can begin to occur. This is a serious acute infection (bacterial, viral, or fungal), where it is necessary to significantly reduce doses of immunosuppressives. At the time of reduced immunosuppression, the immune system can recognize the transplanted kidney as foreign to the human body and begin to fight against it. In this study, the investigators will monitor antibodies against the transplanted kidney in patients with severe acute infection. A serious infection in this study is one that requires acute hospitalization and reduced doses of immunosuppressive drugs. The researchers will measure the antibodies in the blood upon admission and then in 5 weeks.
In this study, investigators seek to determine whether the timing of antibiotics given to mothers during an elective C-section affects the composition of their infant's gut microbiome. To do this, a randomized controlled trial (RCT) was carried out with women undergoing elective C-sections. These women were either given antibiotics before the skin incision (AB+) or after the umbilical cord was clamped (AB-).
Exit site infection (ESI) is one of the major predisposing factors to peritoneal dialysis (PD) related peritonitis. Chlorhexidine Gluconate (CHG) has been widely used for cutaneous disinfection for half a century. TegadermTM CHG is a water-proof dressing with gel pads that provide 2% CHG to the skin surface and effectively prevents catheter-related infections for intravascular catheters. However, its use has not been accessed in patients with PD catheters. We aim to evaluate the effectiveness of TegadermTM CHG dressing in preventing ESI in PD patients.
The aim of the study was to assess the efficacy and safety of AP203 preparation (RESCOVIN®) in a group of patients with increased incidence to viral and/or bacterial upper respiratory tract infections.
To compare the results obtained by analysis of a self-collected anterior nasal (AN) swab as part of the Labcorp COVID-19+Flu+RSV Test Home Collection Kit to a healthcare provider (HCP)-collected AN swab in patients with symptoms of viral respiratory infection consistent with influenza A (Flu A), influenza B (Flu B), respiratory syncytial virus (RSV) and/or SARS-CoV-2 (C-19).
This study aimed to assess the serum Galectin-3 levels in patients with warts both before and after cryotherapy and to investigate its potential contribution to the pathogenesis of human papillomavirus infection.
This observational clinical study aims at the identification of novel biomarkers and causative factors of complicated and/or protracted Epstein-Barr virus-associated infectious mononucleosis (IM). Clinical, biochemical, and routine virological data were collected from 200 patients with IM, novel analytical tools were implemented, and immunological and virological experimental data were generated using blood samples and mouthwashes. Patients have been investigated within four weeks after the onset of symptoms as well as one month and six months thereafter.
