Researchers are studying pulmonary arterial hypertension PAH, including its common subtypes idiopathic PAH IPAH and connective tissue disease-associated PAH PAH-CTD. The study aims to develop pulmonary vascular biomarker signatures using hyperpolarized 129Xe MRI to differentiate these subtypes and to evaluate the ability of this imaging to monitor disease progression and treatment response over time. Additional assessments such as laboratory tests, echocardiography, and six-minute walk distance 6MWD are also used to support these evaluations. The study is observational and enrolls 20 subjects divided into two groups 10 with IPAH and 10 with PAH-CTD. Participants will undergo hyperpolarized 129Xe MRI and MR spectroscopy at baseline, 3 months, 6 months, and 12 months. Alongside imaging, data from standard clinical assessments including labs, echocardiography, and 6MWD will be collected at these same timepoints to track changes. Participants will be monitored for changes in pulmonary vascular remodeling, red blood cell oscillation amplitude, 6MWD, NTproBNP levels, and WHO functional class over one year. Safety is assessed by tracking adverse events, serious adverse events, withdrawals, and specific examinations such as electrocardiograms and vital signs. The total follow-up period for each participant is one year, with multiple scheduled evaluations to comprehensively assess disease status and response.

Researchers are investigating the specific targets of T cells involved in autoimmune diseases by studying tissues from patients with active organ inflammation caused by autoimmune conditions. The study aims to identify which T cells are activated and expanding in diseased tissues compared to blood or normal tissues. This information will help discover new peptide targets and their associated T cell receptors TCRs to develop potential new therapies for autoimmune diseases. Participants will provide tissue samples and matched blood samples during clinical procedures such as endoscopy, arthrocentesis, lumbar puncture, skin biopsy, bronchoscopy, or surgery, depending on their autoimmune condition. The study includes several groups covering diseases like Crohns disease, ulcerative colitis, celiac disease, ankylosing spondylitis, multiple sclerosis, scleroderma, systemic sclerosis, and other autoimmune diseases. Samples may come from excess clinical materials or research-specific biopsies, with the possibility of serial sampling over time. During the study, participants will undergo standard clinical procedures with collection of additional tissue or fluid samples and companion blood draws. Researchers will analyze these samples to identify peptide targets linked to disease-reactive T cells over a period of up to three years. The study includes comprehensive assessments of tissues and blood to understand T cell activity in autoimmune disorders, with monitoring of participant safety and no interventions beyond routine clinical care.

Researchers are studying the use of unlicensed cryopreserved cord blood units CBUs for transplantation in both children and adults with blood cancers and other related disorders. This observational study involves patients with hematologic malignancies and various inherited and acquired disorders affecting the blood and immune system. The main goal is to monitor how well neutrophil recovery occurs after transplantation using these unlicensed CBUs in multiple institutions. Participants receive unlicensed cryopreserved CBUs as part of their transplant treatment. The study includes patients of any age receiving these CBUs for approved indications. The protocol focuses on the access and distribution of these unlicensed units rather than a specific treatment intervention. The study gathers data from recipients who receive these CBUs, tracking outcomes after transplantation. Participants are monitored for neutrophil recovery at 60 and 100 days after transplant, defined by a neutrophil count of at least 500mm3. Researchers also collect information on infection transmission, infusion reactions, survival rates at one year, and incidence of acute and chronic graft versus host disease. Platelet recovery is also evaluated. Safety and efficacy outcomes are followed over time to better understand the effects of unlicensed CBUs in this patient population.
