NCT ID: NCT06211621 Completed - COVID-19 Pandemic Clinical Trials

Admission Pattern Among Children With Gastro-intestinal Infections Before and During the Covid-19 Pandemic

Start date: January 2017
Phase:
Study type: Observational

During the Covid-19 pandemic, admission patterns for infections other than Covid-19 have changed dramatically among children worldwide. Particularly admissions due to respiratory infections and later invasive streptococcal infections have been well documented. However, few studies have compared rates af gastro-intestinal infections during the pandemic with the previous years. This study aims to compare the number and characteristics of children hospitalized with gastrointestinal infections before the COVID-19 pandemic, to the first strict lockdown in 2020 and to the second, less strict lockdown in 2021. A retrospective review of medical records will be performed, of patients aged 1 month to 5 years admitted with gastroenteritis at the pediatric department at Slagelse Hospital in Denmark over a period from 2017 to 2021.

Infectious Prospective Collection for Biological Analysis

Infectieux1
Start date: May 18, 2019
Phase:
Study type: Observational

The increase in activity within medical biology laboratories linked to the arrival of new markers (in cardiology, oncology, infectious diseases, etc.) and the acceleration of technical progress have created a prominent place for automated systems and their reagent kits within these establishments. It is in this context that CerbaXpert took the initiative to set up this research project for the collection of prospective biological samples and their analysis. It transcribes both a process of continuous improvement but also scientific development, making it possible to provide new and/or complementary data in order to improve the operation of automated systems and their reagents within medical biology laboratories. These data obtained in current practice via this study will also be compared with the technical information provided by the manufacturers of the reagents and their automatic devices.

Genetic Susceptibility to Severe Infections

PREDISPOSITI
Start date: November 2, 2023
Phase:
Study type: Observational

Only a fraction of individuals infected with microbes develop clinical disease. This observation raises fundamental questions about the pathogenesis of infectious diseases. There is a complex interaction between environmental (microbial and non-microbial) and human (genetic and non-genetic) factors. This will determine the quality of the immune response against the infectious agent and the clinical manifestation. By definition, individuals who die from an infection have defective immunity to the pathogen in question (immune agent (immune deficiency). The investigation of individual variability in the development of infectious diseases began in the early 20th. The first evidence to support the hypothesis that individual variability variability and immune deficiencies were hereditary came from observations of familial cases or genetic isolates genetic isolates (from a homogeneous population) of rare or common infectious diseases, which in some cases Mendelian heredity hat predisposition to infectious diseases runs in families even more so than diseases associated with less determined environmental factors, such as certain cancers. such as certain cancers. Finally, studies comparing the rate of concordance of infectious diseases between monozygotic and dizygotic twins also implicate genetic factors in disease susceptibility. These observations were validated by the discovery of genetic defects associated with severe infectious diseases, leading to proof of concept. While a number of hereditary immune deficiencies associated with susceptibility to multiple pathogens or microorganisms, a growing number of new and rare new and rare immune deficiencies conferring restricted susceptibility to infections caused by a single caused by a single pathogen family, or even a single pathogen, in otherwise healthy children, have recently been identified (one gene, one pathogen). As a result, a dozen Mendelian clinical syndromes characterized by restricted susceptibility are now known. Over the last 20 years, it has been proven that these "idiopathic" infections were immune deficiencies. The investigators now wish to study new severe infections, including but not limited to viral, fungal and bacterial infections. viral, fungal, bacterial and parasitic infections. This should lead to a better understanding of the pathophysiology of each disease, the development of new therapeutics and better patient care.

NCT ID: NCT06063330 Completed - COVID-19 Clinical Trials

Clinical Trial to Evaluate the Safety of RQ-01 in SARS-CoV-2 Positive Subjects

Start date: September 27, 2023
Phase: Phase 1
Study type: Interventional

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.

Evaluation of Tolerance and Pharmacokinetic Profile of High Doses of Favipiravir in Healthy Volunteers

FAVIDOSE
Start date: March 2024
Phase: Phase 1
Study type: Interventional

FAVIDOSE trial is a Phase I randomized, double blind controlled, monocentric, dose escalation clinical trial. The primary purpose of this trial is to evaluate tolerance of high doses of favipiravir for 14 days in healthy volunteers. This trial also looks to characterize favipiravir pharmacokinetics in blood and favipiravir levels in sperm. A pharmacogenetics analysis will be conducted in an attempt to identify genetic variants of metabolism and transport enzymes of favipiravir to explain the inter-individual variability of pharmacokinetic parameters of favipiravir. Three sequential dose levels including distinctive participants: - level 1: D1: 2400 mg BID; D2 to D13: 1600 mg BID and D14: 1600 mg in the morning; - level 2: D1: 2400 mg BID; D2 to D13: 2000 mg BID and D14: 2000 mg in the morning; - level 3: D1: 2400 mg BID; D2 to D13: 2400 mg BID andD14: 2400 mg in the morning. Three study groups of maximum of 8 participants, 6 receiving favipiravir and 2 receiving placebo per dose level, three dose levels proposed. Seven additional participants with the same follow up will be included and randomized (6:1 ratio) at the maximum tolerated dose level to allow a satisfactory accurate characterization of pharmacokinetics and pharmacogenetics of favipiravir and their determinants (maximum 39 participants in total, taking into account 8 participants - 2 per dose level - replaced because loss of follow-up before the end of treatment).

Antibiotics for Delirium in Older Adults With No Clear Urinary Tract Infection

A-DONUT
Start date: September 2023
Phase: N/A
Study type: Interventional

Delirium is an acute confusional state that is experienced by many older adults who are admitted to hospital. To treat delirium the underlying cause needs to be identified promptly, but this is challenging. One of the potential causes of delirium is infection. Urine tests show that most patients experiencing delirium have bacteria in their urine, however, bacteria in the urine is common among older adults, and does not automatically indicate an infection is present. As a result it is difficult to know whether a lower urinary tract infection is present as individuals with delirium are frequently unable to report clinical signs of infection - symptoms of pain or discomfort with urination, having to urinate more frequently or pelvic discomfort. Very often, individuals with delirium are treated with antibiotics despite the fact that it is unknown whether antibiotics help to improve delirium in cases where bacteria in the urine is present. This proposed study is a randomized controlled trial that will examine if adults (age 60 or older) with delirium and suspected infection benefit from taking antibiotics.

Rickettsia Clearance Study

RiCS
Start date: March 20, 2024
Phase: Phase 2/Phase 3
Study type: Interventional

Murine typhus is a disease caused by Rickettisa typhi, an obligate intracellular bacterium transmitted by rodent fleas. The disease has a worldwide distribution; however the true burden is unknown, related to its non-specific presentation and lack of access to diagnosis in many regions. A systematic review of untreated murine typhus based on observational studies of a total of 239 patients has estimated the mortality associated with the disease at between 0.4% and 3.6%. Scrub typhus is caused by Orientia tsutsugamushi and transmitted by the larval stage of chigger mites (Trombiculidae family). It has been estimated to affect at least one million people each year. A systematic review found varying reports of the mortality associated with untreated scrub typhus ranging from 0-70% (median 6%). Polymerase chain reaction (PCR) based diagnosis of rickettsial infections is only available in one centre (Mahosot Hospital) in Vientiane. A number of hospitals use a variety of point-of-care antibody tests to diagnose rickettsial infections however many of these have not been validated and they are of uncertain sensitivity and specificity. In 2006 results of a two year prospective study of 427 patients presenting to Mahosot Hospital with a febrile illness and negative blood cultures showed that 115 (27%) patients had an acute rickettsial infection, confirmed by serological testing. Among these patients, 41 were diagnosed with murine typhus and 63 with scrub typhus. Antibacterial agents with activity against rickettsial pathogens include doxycycline, azithromycin, chloramphenicol and rifampicin. Azithromycin is often reserved for pregnant women or children below the age of 8 years due to lasting concerns after the tetracycline-associated staining of growing bones and teeth in the past. Evidence is accumulating that doxycycline is superior to azithromycin for the treatment of rickettsial disease. Clinical treatment failures have occurred following azithromycin treatment of murine typhus. The relationship between rickettsial bacteria load and both disease severity and response to treatment has not been characterised. Rickettsial concentrations in blood are generally low, of the order of 210 DNA copies/mL blood for R. typhi and 284 DNA copies/mL blood for O. tsutsugamushi. At present, there is no standard antibiotic susceptibility testing (AST) method for R. typhi and O. tsutsugamushi. The gold standard method for AST for Rickettsia pathogens is the plaque assay which determines minimal inhibitory concentration (MICs) from the smallest antimicrobial concentration inhibiting rickettsial plaque forming unit formation. This method is laborious and time consuming, taking approximately 14-16 days based on species to yield a result. Molecular detection methods are useful for diagnosing patients infected with rickettsial pathogens and has been applied for antibiotic susceptibility testing. Antibiotic susceptibility testing based on DNA synthesis inhibition detecting by quantitative PCR (qPCR) for O. tsutsugamushi clinical isolates has been reported. However, the relationship between antibiotic susceptibility profiles and treatment response has not been studied. There is a need to develop a reliable ex vivo method to characterize the treatment response and compare susceptibility of R. typhi and O. tsutsugamushi to different agents.
