Filter by:The goal of this observational study is to map the pathogen profile of secondary infections in liver transplant recipients, to correlate the basic immune status with the characteristics of the secondary infection pathogen profile, and to establish an early warning system for monitoring secondary infections, so as to explore safe and effective therapeutic modalities to further reduce the morbidity and mortality of liver failure. The main questions it aims to answer are: - Characterize the distribution of pathogenic bacteria infecting liver transplant recipients. - Establish a monitoring and early warning system for secondary infections.
This is a prospective, observational, pilot trial to evaluate the feasibility of heart transplantation using normothermic regional perfusion (NRP) donation after donor circulatory death (DCD). Adults who meet standard criteria for heart transplantation listing and study-specific eligibility criteria will enroll in the study. the investigators anticipate evaluating an initial cohort of approximately 100 DCD donors for a final yield of 40 hearts. The investigators will accept donors between the ages of 18 and 65 who are determined to have heart function/quality appropriate for donation for transplantation based on available donor data and testing. If feasible, donors might be relocated to BUMCP to maintain uniformity of process, minimize cold ischemic time, and allow for more rapid and improved communication during the initial pilot phase. Recipients will be selected based on blood group, crossmatch, size match, and clinical stability per standard allocation practices. Recipients will be followed post-transplantation per BUMCP Heart Transplant standard protocol.
COVID-19 is a global major public health emergency that disproportionately affects patients with risk factors such as advanced age, heart and lung disease, diabetes, hypertension, as well as compromised immunity. Despite the recent worldwide emergence of this disease and its rapid progression to a pandemic, very little is known about the risks facing solid organ recipients. The study aims to elucidate the prevalence of symptomatic, subclinical, and asymptomatic infection in the transplanted population by assessing their immunological response to SARS-CoV-2 infection. This will be studied seroepidemiologically in the whole cohort and retrospectively in transplanted patients admitted to hospital for COVID-19. Primary objective: to elucidate the cumulative prevalence of SARS-CoV-2 infection in the transplanted population related to symptoms and hospitalizations; to assess the magnitude of immunological response and seroconversion kinetics for COVID-19. Secondary objectives: To examine the influence of medical parameters on COVID-19 infection and immune response such as: age, comorbidities current and recent pharmacological treatment, organ transplanted, and blood type, HLA genotype. Study design: Part 1: Longitudinal cohort study for seroepidemiology and disease burden. Part 2: Retrospective case-series for seroconversion kinetics and clinical course assessment. Study population: All solid organ transplanted patients in Sweden
