Filter by:In this study, the investigators aim to collect phenotypical and extensive unbiased multimodal biological data, at two different time points, and to integrate them using a systems biology approach. The present project aims at generating a systems biology network that can recapitulate the complexity of processes underlying differential SARS-CoV-2 phenotypic responses through exploitation of clinical -omics data. Identifying key determinants and mechanisms of biological variability responsible for phenotypic differences will lead to a better management of patients through the application of precision medicine.
The participants are being asked to take part in this clinical trial, a type of research study, because the participants are scheduled to receive or have recently received a hematopoietic cell transplant (HCT) or a solid organ transplant (SOT). Primary Objective To determine if pre-transplant screening for respiratory viral load predicts RVI within 1- year post-transplant among survivors. Secondary Objectives: - To develop and validate a classifier based on pre-transplant immunological profile predictive of developing an acute respiratory viral infection (aRVI), with RSV/PIV3/HMPV/SARS-CoV-2 through one-year post-transplant among survivors. - To develop and validate a classifier based on Day +100 post-transplant immunological profiles predictive of developing an acute respiratory viral infection (aRVI),with RSV/PIV3/HMPV/SARS-CoV-2 through one-year post-transplant among survivors .
This is a Phase II, multicenter, open-label, randomized, standard of care (SOC) controlled, multiple ascending dose study to assess the safety and tolerability of IV Brincidofovir (BCV) in subjects with BKV infection after kidney transplantation. The study will be conducted at multiple study sites in several countries including Australia and Japan. Subjects who meet eligibility criteria will be enrolled in the study and will be randomized and assigned to BCV or SOC (defined as use of the same immunosuppressant administered during prescreening) before receipt of the first dose of study drug in both the Dose Escalation Phase and the Expansion Phase.
Background: Ebola virus disease (EVD) is a viral fever that can cause internal bleeding. The death rate from EVD is very high. In a 2014 outbreak in West Africa, 28,000 were affected and 11,000 died. EVD may also affect the brain and nervous system, but this is not well studied. People with EVD report headaches and mental status changes. Some rarely had strokes and seizures. Neurological issues can continue for years after people recover from the initial EVD infection. Objective: This is a natural history study to learn more about how EVD continues to affect survivors brain and nervous system after 5 years. Eligibility: People aged 18 years or older who participated in the PREVAIL III Neurology Substudy. Participants can be either an EVD survivor or a close contact. Close contacts are people who had a relationship with a survivor of EVD. Design: Participants will have 1 clinic visit. They will have a physical exam. Their vital signs will be measured. They will also have a neurological checkup. The exam will assess their mental status. Their senses, reflexes, and coordination will be tested. They will be observed while walking to assess their gait. This exam will take about 1 hour. Participants will have an interview. They will answer questions about any symptoms they have that may be affecting the brain or nervous system. This will take about 1 hour. No other procedures will be performed during this visit.
The purpose of the study is to determine the feasibility, safety and efficacy of administering rapidly-generated donor-derived pentavalent-specific T cells (Penta-STs) to mediate antiviral and antifungal activity in hematopoietic stem cell transplant (HSCT) recipients with AdV, EBV, CMV, BKV or Aspergillus fumigatus (AF) infection/ reactivation or with active disease.
This study aims to conduct a 12-month randomized controlled trial to adapt the mobile app, WiseApp, and a smart pill dispenser for Spanish-speaking people living with HIV (PLWH) in the New York City (NYC) area and La Romana, Dominican Republic (DR). The study will assess the efficacy and sustainability of WiseApp as well as identify barriers with its widespread use among Spanish speakers. With disproportionately high rates of HIV in the New York City area and the Dominican Republic, this project seeks to identify distinct contextual factors related to Spanish speaking people living with HIV and increase the likelihood of engagement with technology and improvements in clinical outcomes.
Hepatitis B virus (HBV) infection is a major global health issue with 257 million chronically infected individuals. Of note, China has the largest population accounting for one third of the world's infected population. Approximately, about 300 000 people die each year due to the consequences of HBV. In 2016, the World Health Organization (WHO) proposed the goal for elimination of hepatitis B as public health threat by 2030 and China will be a major contributor towards this global goal. Currently, two approved therapeutic strategies are available including pegylated interferon (IFN) or nucleos (t) ide analogues (NA), which could suppress HBV replication and slow disease progression. Here, investigators hope to launch a cohort study to reveal the clinical features relating to therapeutic efficacy of antiviral therapy and the prognosis of patients with differential therapeutic strategies.
Recent advances have been made in prevention of the viral infection via vaccines but there is still need for effective treatment options for patients. Novel therapies need to be developed to further improve clinical outcomes. The biggest medical challenge in the response to COVID-19 is ARDS requiring hospitalization in an intensive care setting and ventilator dependence. Intravenously administered umbilical cord derived exosomes and stem cells have been reported in literature to alleviate pulmonary distress in such patients. The purpose of this study is to explore the safety and benefits of intravenous administration of WJPure and EVPure in the treatment of COVID-19 patients with moderate to severe ARDS. .
This study is a prospective single-arm clinical study, focusing on Epstein-Barr virus-associated hemophagocytic lymphohistiocytosis and Chronic Active Epstein-Barr Virus Infection with only and mainly B lymphocytes of EBV infection, to evaluate the clinical efficacy of Rituximab in the treatment of EBV-HLH and CAEBV.
The study aims to demonstrate that antiviral therapy for patients with immune tolerance of CHB. On the basis of the original antiviral therapy of entecavir, further clarify the safety and effectiveness of entecavir combined with tenofovir amibufenamide.The investigators plan to enroll about 328 hepatitis B patients,. who are in the stage of immune tolerance. These participants will be devided into two groups randomly .Group A will receive the treatment of entecavir. Group B will be treated with entecavir and tenofovir amibufenamide. The participants in both groups will be followed up for 96 weeks. The primary endpoint is to compare the inhibition rate of HBV-DNA between two groups. The secondary endpoint includes: (1) Comparing the decrease of HBV DNA at 48 weeks between the two groups. (2) Comparing the HBeAg seroconversion rates at 48 weeks and 96 weeks between the two groups. (3) The changes of HBsAg at 48 weeks and 96 weeks between the two groups. (4) Comparing adverse side effects between the two groups.
