Filter by:The iParent2Parent (iP2P) program is a new, innovative virtual mentorship program that will connect parents one-to-one with other parents of pediatric solid organ transplant (SOT) recipients who are trained to offer vital peer support and mentorship. Parents of children who received a SOT at The Hospital for Sick Children will be invited to participate as mentors and mentees (randomized into the iP2P or control group). The iP2P program can decrease feelings of isolation, improve mental health and have a long-term positive impact on patient health. This research will increase our understanding of one-to-one peer support and leverage eHealth technologies to improve the access to and acceptability of parent peer support interventions.
In solid organ transplant (SOT) the receipt of influenza vaccine in an influenza season is associated with decreased disease severity as demonstrated by the presence of pneumonia and ICU admissions. Different strategies have been assessed to optimize vaccine efficacy and immunogenicity of the influenza vaccine in the solid organ transplant recipient (SOTR). The primary objective of the study is to evaluate the immunogenicity of 2 doses of the high dose influenza vaccine utilizing neutralizing antibody assays. A control group receiving 1 HD influenza vaccine will be included.
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 study is being done because the investigators would like to learn more about how well the COVID-19 vaccine works in participants with cancer or those who have received a transplant or cellular therapy. Primary Objective Assess the immunogenicity to COVID-19 vaccination in patients with cancer and/or transplant and cellular therapy (TCT) recipients. Secondary Objectives - Evaluate the antibodies response to COVID-19 vaccination in immunocompromised patients. - Evaluate the T cell response to COVID-19 vaccination in immunocompromised patients. Exploratory Objectives - Assess incidence and severity of COVID-19 infections by 6 months following immunization with a SARS CoV-2 vaccine. - Assess the durability immune response to COVID-19 vaccination. - Assess the immunogenicity of COVID-19 vaccination in immunocompetent children and adolescents without cancer and have not undergone transplant or received cellular therapy.
The Coronavirus Disease 2019 (COVID-19) pandemic has claimed over 5 million lives globally. Fortunately, a substantial and growing number of SARS-CoV-2 vaccines with very high efficacy have been developed, manufactured, and rapidly approved. Novel mRNA vaccines such as the BNT162b2 (Pfizer-BioNTech) and mRNA-1273 (Moderna) have reported a stunning >94% efficacy against COVID-19. However, global access has not been equitable, with many low- and middle-income countries having no vaccine access or access under emergency use mainly to traditional inactivated SARS-CoV2-2 vaccines such as BBIBP-CorV (Sinopharm Beijing), CoronaVac (Sinovac) and BBV152 (Bharat Biotech). Emerging studies have shown that lower concentrations of neutralizing antibodies (Nab) are attained after CoronaVac than after an mRNA-based vaccine in healthy individuals. This difference seems to be more pronounced in immunocompromised patients who are at higher risk of severe COVID-19 and death from COVID-19. As such, several countries including the United States, Israel and Chile have recommended a third vaccine dose for high-risk populations. However, it is not currently known which is the best vaccine combination regarding immunogenicity, particularly in these vulnerable patients. This observational study will explore the humoral and cellular response to a SARS-CoV-2 BNT162b2 vaccine booster in solid organ transplant patients who received two previous doses of the inactivated Coronavac or two doses of BNT162b2 vaccines.
While hematopoietic stem cell transplant (HSCT) is an effective therapy, graft versus host disease (GVHD) is the most significant complication after HSCT. Both acute GVHD and chronic GVHD are leading causes of non-relapse morbidity and mortality. Patients with solid organ transplants may participate in this study as well because these patients occasionally develop acute GVHD, which is biologically similar to acute GVHD after an HSCT. Acute graft versus host disease usually occurs within the first 100 days of transplant and can involve the skin, gut, or liver. Chronic graft versus host disease usually occurs after the first 100 days of transplant and can involve skin, eyes, mouth, joints, liver, intestines commonly. These two diseases are different, but both happen due to the imbalance of the donor immune system in the host. The purpose of this research is to learn more about ruxolitinib as a treatment for both acute and chronic GVHD. Specifically, the investigators would like to learn more about the pharmacokinetics (PK - the process of absorption, distribution, metabolism, and elimination from the body - meaning how the drug moves through the body) and the pharmacodynamics (PD - the body's biological response to the drug) of ruxolitinib.
Prospective, multicenter, non-comparative cohort study of immunocompromised people vaccinated against Covid-19 with the aim to know the humoral and cellular response to BNT162b2 vaccination against SARS-CoV-2 variants. This study will enroll patients in 5 parallel sub-cohorts of the same size, distinct according to the source of the immunosuppression: autoimmune or auto-inflammatory disease, HIV infection, multiple sclerosis, solid cancer, organ transplantation with prospective data collection and constitution of biological collections.
This study is designed to determine if an innovative mobile health intervention designed to improve patient-provider communication can reduce unscheduled hospitalizations, and visits to the emergency department and ambulatory clinic in adult heart, liver, and kidney transplant patients.
The influenza virus is a significant cause of morbidity in adult solid organ transplant (SOT) recipients. However, these individuals show a suboptimal response to vaccines including the standard-dose (SD) inactivated influenza vaccine (IIV). Recent studies have investigated two strategies to overcome poor immune responses in SOT recipients: (1) administration of high-dose (HD)-IIV compared to SD-IIV and (2) two doses of SD-IIV compared to one dose of SD-IIV in the same influenza season. The first study compared HD-IIV vs. SD-IIV in adult SOT and noted HD-IIV was safe and reported higher immunogenicity; however, the median post-transplant period was 38 months. In another phase II trial of adult SOT recipients, two doses of SD-IIV a month apart compared to one-dose SD-IIV revealed increased immunogenicity, with a median post-transplantation period of 18 months. Therefore, these studies lack evaluation in the early post-transplantation period in this vulnerable population when influenza disease is most severe. The administration of two-doses of HD-IIV in the same influenza season has also not been studied in SOT recipients. Moreover, the vast majority of SOT influenza vaccinations studies have not substantively evaluated prolonged immunogenicity. Thus, the optimal immunization strategy for SOT recipients less than 12 months post-transplant is poorly-defined. In addition, the immunologic predictors and correlates of influenza vaccine immunogenicity in SOT recipients have not been defined. The investigators hypothesize that adult solid organ transplant recipients that are 1-11 months out from transplant and are receiving high-dose inactivated influenza vaccine will have higher hemagglutination inhibition (HAI) geometric mean titers to influenza A antigens compared to adult SOT recipients receiving standard-dose inactivated influenza vaccine. To test this hypothesis and address the above critical knowledge gaps, The investigators propose to conduct a phase II multicenter randomized controlled trial comparing either two doses HD-IIV, two doses of SD-IIV, or one-dose of HD-IIV in adult kidney, heart, and liver SOT recipients 1-11 months post-transplantation. The results of this study will address significant gaps in knowledge regarding influenza vaccine strategies and immune responses in adult SOT recipients and will guide vaccine recommendations in this vulnerable population.
The purpose of this research study is to learn more about the use of viral specific T-lymphocytes (VSTs) to treat viral infections that may happen after solid organ transplant (SOT). VSTs are cells specially designed to fight viral infections that may happen after a solid organ transplant. These cells are created from a blood sample collected from the study participant. Solid organ transplant and the use of immunosuppressive medications reduces the body's ability to fight infections. Viral infections are a common problem after transplant and can cause significant complications. Reduction of immunosuppression may put the organ at risk of rejection. Moreover, treatment of viral infections is expensive and time consuming, with families often administering prolonged treatments with intravenous anti-viral medications, or patients requiring prolonged admissions to the hospital. The medicines can also have side effects like damage to the kidneys or reduction in the blood counts, so in this study the investigators are trying to find a better way to treat these infections and minimize complications.
