Active clinical trials for "Virus Diseases"

Background: Aim: To demonstrate the efficacy of low-dose hydroxychloroquine as primary prevention in healthcare workers Design, participants and interventions: Prospective, randomized, parallel group, double-blinded, placebo controlled, study. including 440 participants who will be randomised to 2 treatment arms: hydroxychloroquine or placebo. Outcome variables: symptomatic or asymptomatic SARS-CoV-2 infection confirmed by PCR, viral load during SARS-CoV-2 infection, seroconversion during the study period, incidence of any acute respiratory infection, days of sick leave. Statistical considerations: No trials have been published investigating the efficacy of HCQ as primary prophylaxis of SARS-CoV-2 infection in health care workers. Thus, sample size calculations in the proposed trial are based on the investigators' best estimates for several parameters. In accordance to the effect of oseltamivir against symptomatic influenza, we assumed an approximate effectiveness of approximately 60% (HR of 0.4) (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6464969/) as realistic. As a prophylactic intervention with HCQ, which may have side effects and for which supply shortage can be expected, was judged justifiable only if its effectiveness is high, we based our sample size consideration on a HR of 0.3. To estimate the probability of an event in both the experimental and the control group, very little data is available. In a Dutch point-prevalence study 0-10% of health-care workers were infected depending on the healthcare institution, depending on the hospital. This point-prevalence study was performed between 6 and 9 March, when the reported number of cases in the Netherlands was 33 and 77, respectively, according to the RIVM (https://www.rivm.nl/nieuws/resultaat-steekproef-4-ziekenhuismedewerkers-heeft-coronavirus). Additionally, in an a report published in the Lancet, 20% of responding healthcare workers in Italy were found to be infected with SARS-CoV2 within less than one month (https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)30627-9/fulltext). Several media reports indicate that this proportion is similar across various healthcare institutions and countries (https://www.nytimes.com/2020/03/24/world/europe/coronavirus-europe-covid-19.html) and (https://www.aljazeera.com/news/2020/03/spain-tightens-restrictions-week-lockdown-begins-200330191539568.html). As the proposed study will be performed in a high-risk setting, we assumed an event (i.e. PCR positivity) probability of 10% in the control group and 3% in the experimental arm after the maximum study period. In summary, a sample size of 210 participants per arm is necessary to detect a HR of 0.3 with a power of 80.3% with an alpha-error of 0.05. To account for drop-outs and asymptomatic, undetected infection at inclusion or past infection with existing immunity, an additional 10 participants will randomized per treatment arm. The overall study population is therefore 440 participants. Statistical analysis will be based on two populations: A Modified Intention to Treat population excluding those who withdrew consent after randomization and those with a positive serology at baseline. And a per protocol population including all randomized subjects who completed at least 3 out of 4 follow-up visits and took at least 80% of all doses of study medication.

The purpose of this study is to determine whether multiple therapeutic regimens are effective in the treatment of Ebola Virus Disease (EVD)

A randomized, double-blind, phase II-02 clinical trial is to evaluate the safety and immunogenicity of an inactivated EV71 vaccine with or without aluminum adjuvant

Study Purpose: The purpose of this study is to assess that Liquid Acupuncture(Herb Acupoints Injection) Therapeutics could achieve permanent efficacy response in Chronic Hepatitis B. Efficacy Assessment: At cessation of the Treatment(about at 24 weeks)comparing Testing Data with the Normal Criteria and their individual baseline.Continue for monitoring the Status 1-5 years. Data Analysis: Each 4 weeks collecting Patients' testing data and fill a table.A summary table will be presented as frequency tables for categorical variables as number or percentage.

Entecavir(ETV) plus Tenofovir Disoproxil Fumarate(TDF) combination will show effective antiviral activity and prevent further development of antiviral resistance in hepatitis B e antigen(HBeAg)-positive or -negative Chronic Hepatitis B(CHB) patients who experienced multidrug resistance All subjects will orally take investigational drugs once daily for 48 weeks. All subjects will be assessed at baseline, Week 4, 12, 24, 36 and 48. Evaluations at each visit will include vital signs, physical examinations, laboratory tests and HBV DNA levels. They were also questioned about adverse events and concomitant medications. At baseline and every six months thereafter, serum will be assayed for HBV serology. Genotypic analysis will be performed at baseline and 48 weeks.

COVID-19 DISEASE Coronavirus disease 2019 (COVID-19) is a respiratory tract infection caused by a newly emergent coronavirus, severe acute respiratory syndrome from COVID-19, that was first recognized in Wuhan, China, in December 2019. While most people with COVID-19 develop mild or uncomplicated illness, approximately 14% develop severe disease requiring hospitalization and oxygen support and 5% require admission to an intensive care unit. In severe cases, COVID-19 can be complicated by acute respiratory disease syndrome (ARDS) requiring prolonged mechanical ventilation, sepsis and septic shock, multiorgan failure, including acute kidney, liver and cardiac injury. ARDS REHABILITATION Critically ill people who undergo prolonged mechanical ventilation often develop weakness, with severe symmetrical weakness of and deconditioning of the proximal musculature and of the respiratory muscles (critical illness neuropathy/myopathy).These individuals also develop significant functional impairment and reduced health-related quality of life (HRQL) up to 2 and 5 years after discharge. ARDS survivors may complain of depression, anxiety, memory disturbances, and difficulty with concentration often unchanged at 2 and 5 years. Less than half of all ARDS survivors return to work within the first year following discharge, two-thirds at two years, and more than 70% at five years. Early physiotherapy (PT) of people with ARDS has recently been suggested as a complementary therapeutic tool to improve early and late outcomes. The aims of PT programs should be to reduce complications of immobilization and ventilator-dependency, to improve residual function, to prevent new hospitalisations, and to improve health status and HRQL. Physiotherapy in critical patients is claimed also to prevent and contribute to treat respiratory complications such as secretion retention, atelectasis, and pneumonia. Early mobilization and maintenance of muscle strength may reduce the risk of difficult weaning, limited mobility, and ventilator dependency. Lastly, pulmonary rehabilitation in ICU in mechanically ventilated subjects may reduce length of stay in ICU up to 4.5 day, shorten mechanical ventilation of 2.3 days and weaning by 1.7 days. The aim of this study is to investigate how early pulmonary and motor rehabilitation impacts on length of hospital admission (ICU and acute ward) and early and late outcomes inpatients that develop ARDS due to COVID-19.

The aim of this study is to investigate the immunogenicity response in adults up to 10 years after one booster dose. Data collected from this study will allow for greater information to prescribers who administer TBE vaccine, so that they can appropriately time the administration of booster vaccinations to individuals who received different vaccination schedules and who live in tick borne encephalitis endemic regions.

Objective: Determine the genotypes and risk factors associated with human papilloma virus infection in Mexican women. Methods: It was a cross-sectional study of women attended at the Materno-Perinatal Hospital "Mónica Pretelini" and the Medical Research Center (CICMED), who were asked to complete a risk factor questionnaire and submitted to colposcopy to identify SIL. Cervical swab samples were obtained to perform linear array HPV genotyping test (Roche®, Mannheim, Germany).

ANTOINE is a prospective trial which aims to assess diagnostic performance of 7 biomarkers for the diagnosis of severe bacterial infections (SBI) in children aged from 7 days to 36 months. Fever is a frequent cause of consultation in pediatric emergency departments. Clinical diagnostic tools are rare and discrimination between severe bacterial infection and viral infection is difficult to confidently state. The prevalence of severe bacterial infections (IBS) varies from 10 to 25% according to the studies. Biological markers such as procalcitonin (PCT) and C-reactive protein (CRP) are commonly used in clinical practice. These markers have bacterial specificity but share a wide range of values with viral infections and do not make it possible to exclude or to confirm definitively the diagnosis of IBS. The use of new markers to improve the diagnosis of bacterial and viral infections is increasingly studied in adults. The diagnostic value of these new markers has been demonstrated by associating their dosage with that of CRP for example. This is the case for IP-10, TRAIL or MxA. However, very few pediatric studies have been carried out to date on these new biomarkers. However, in pediatrics, these diagnostic tools based on the combination of biomarkers to discriminate against viral and bacterial infections could be a major help in the suspicions of IBS. 7 biomarkers were selected to be evaluated in this study. This study is designed to determine the best biomarkers combination for the SBI diagnosis on a cohort of 800 patients.
