Filter by:There has been no effective predicting tool to accurately predict BKV reactivation after kidney transplantation. The aim is to elucidate the use of flow cytometric analysis for both intracellular cytokines and surface activation markers for BKV-specific T cell response in kidney transplant recipients.
The goal of this decentralized, observational study is to enroll and observe adults in the contingent United States during the 2023-2024 flu season. The main study objectives are to create a dataset of paired wearable data, self-reported symptoms, and respiratory viral infection (RVI) from PCR testing during the 2023-2024 flu season and to develop algorithm that is able to accurately classify asymptomatic and symptomatic RVI and understand the algorithm's performance metrics.
This study investigates the effect of Lactobacillus reuteri probiotic strains (ATCC PTA 5289 and DSM 17938) on symptoms of viral upper-respiratory tract infections in children.
Cystic fibrosis (CF) is the most common hereditary life-threatening condition in Belgium. Because of a dysfunctional cystic fibrosis transmembrane conductance regulator (CFTR) channel, chloride is unable to move to the cell surface and mucus becomes more viscous. Consequently, CF patients are not able to clear their lungs efficiently, and trapped bacteria can lead to chronic infection and inflammation of the lungs, and ultimately respiratory failure. CF lung disease starts at birth due to muco-inflammatory processes and is associated with a significantly altered microbial colonization of the infant airways compared to infants without CF. Additionally, young children with CF suffer from viral infections as often as their healthy peers, but the episodes are more severe and often prolonged. Moreover, frequent viral infections in children with CF contribute towards a more pathogenic airway microbiome at a young age. Although this link has been previously reported, the exact mechanisms by which this occurs need to be elucidated. A pulmonary exacerbation in CF is characterized by an increase in respiratory symptoms, general symptoms and a decline in lung function. Most young children with CF suffer from a mean of 4 exacerbations per year for which antibiotics are prescribed. Despite the current novel therapies in CF, treatment of respiratory infections stay relevant and is a greater challenge with increasing survival. The key objective of this study is to gain insights into the mechanisms by which viral infections leading to pulmonary exacerbations induce a more pathogenic microbiome in young children with CF. About forty participants will be recruited at the paediatric CF clinic of the Antwerp University Hospital. Inclusion criteria are an age of less than 5 years and a diagnosis of CF. There are no exclusion criteria. Duration of the study is 1 year to cover for seasonality of clinical symptoms. Study visits are scheduled at 3-month intervals corresponding with the regular follow up, or unscheduled during an acute pulmonary exacerbation. From all participants, two oropharyngeal swabs (for microbiome analysis and for immunological/mucin analysis) will be collected at set time points. For the linking of the laboratory data to the clinical characteristics, we will examine demographics, environmental exposures, and disease markers of CF. Next to the collection of the oropharyngeal swabs, a history, physical examination, and technical investigations will be performed at the study visits.
Influenza and other acute respiratory viral infections remain practically uncontrollable diseases due to the high variability of the antigenic structure of influenza viruses and the heterogeneity of pathogens of acute respiratory infections. Therefore, for the prevention and treatment of influenza, acute respiratory viral infections and herpes infections, it is relevant to develop drugs - immunomodulators that mobilize the reserves of nonspecific and specific immune systems and enhance the effects of these systems against the pathogens. The drug CYCLOFERON, 150 mg, enteric-coated tablets, contains the active substance meglumine acridone acetate, which is an interferon inducer. Interferons are the most important system of innate immunity, which has antiviral and immunomodulatory effects, and can protect the body from infection with a virus, and in case of infection, fight the causative agent of the disease. The planned clinical trial of the efficacy and safety of the drug CYCLOFERON in the dosage form of a tablet will study its ability to prevent influenza and other respiratory viral infections in adults who have already had close contact with patients with manifest disease.
Objectives: 1. To compare the immune response of patients with or without sepsis presenting to the ED with a(n) (suspected) infection. 2. To determine immune response aberrations that are associated with an increased risk of developing sepsis in patients presenting to the ED with a(n) (suspected) infection without sepsis. 3. To determine the long term cognitive and physical sequelae of sepsis after admission.
"Formosa 1-Breath Free (NRICM101) " has been widely known in Taiwan to treat COVID-19. However, there is no phase III pivotal clinical trial of "Formosa 1-Breath Free (NRICM101) " . In order to obtain scientific, standardized, and comparable clinical results, the study will be implemented to evaluate the efficacy of safety of "Formosa 1-Breath Free (NRICM101) ". The objective of the study was used the product which be provided by Tian-I Pharmaceutical Co. Ltd. to evaluate the efficacy and safety of the subjects with the symptoms of COVID-19 or Influenza-like after taking "Formosa 1-Breath Free (NRICM101) ". This study is a randomized, double-blind, parallel controlled clinical trial. The study consisted of 3 cycles: screening period, treatment period (5 days) and follow-up period. The treatment of this study is divided into two groups: The test drug is Formosa 1-Breath Free (NRICM101) granule 5g/bag, 3 times a day；The control drug is the placebo (dummy) 5g/bag, 3 times a day. The sample size in the study is at least 150 people who can be evaluated, and the dropout rate of the test is 10-15%. The estimated sample size is around 170 people. After signing the ICF, vital signs (sitting blood pressure, pulse rate, SpO2, respiratory rate and body temperature), physical examination, chest X-ray, and laboratory test will be checked in screening period. Only subjects with clinically acceptable and following the inclusion and exclusion criteria will eligible to enroll in this study. Compliance will be assured by administration of the study drug under the supervision of the investigator or his deputy. Subjects will be free to withdraw at any time without stating any reason. Data will be analyzed from those subjects who complete the entire study; however, the case report forms and the final study report should include reasons for withdrawals and any necessary treatment.
A randomized, Phase 2a, double-blind, placebo-controlled study to evaluate the safety, pharmacokinetics and antiviral activity of multiple doses of orally administered EDP-323 in healthy subjects infected with RSV-A Memphis 37b. This study is designed to assess the antiviral effect of EDP-323 compared to a placebo control in the respiratory syncytial virus challenge model.
The goal of this prospective, interventional, single-center study is to assess whether the early detection of Influenza with smartwatch algorithms and alerting, rapid testing, and subsequent Baloxavir treatment demonstrate better post-infection outcomes versus publicly available- and Centers for Disease Control (CDC)-derived national statistics for equivalent household populations as well as pediatric kidney, heart, liver, lung transplant recipients and waitlisted patients.
The goal of this intervention research is to learn about the safety and tolerability of 162 with a single ascending dose in subjects with chronic hepatitis B virus (HBV) infection.
