Bone Marrow Transplantation

Graft-versus-host disease (GVHD) is a major complication after allogeneic hematopoietic stem cell transplantation (allo-HSCT), significantly affecting survival and quality of life. Acute GVHD (aGVHD) typically occurs within 100 days post-transplant, commonly involving skin, gastrointestinal tract, and liver. Chronic GVHD (cGVHD) can appear months to years later. Despite prophylaxis with calcineurin inhibitors (e.g., cyclosporine or tacrolimus), methotrexate, mycophenolate mofetil, and post-transplant cyclophosphamide (PTCy), patients receiving haploidentical transplantation from parous female donors remain at high risk for moderate-to-severe aGVHD. JAK1-dependent cytokine signaling (IL-6, IFN-γ) is central to GVHD pathogenesis. Selective JAK1 inhibition may attenuate T cell-mediated inflammation while preserving hematopoiesis. Ivarmacitinib (SHR0302) is a highly selective oral JAK1 inhibitor, showing favorable safety and preliminary efficacy in autoimmune and GVHD settings, making it a candidate for early GVHD prophylaxis.

Background Hematological diseases are disorders of the blood and hematopoietic organs. The current hematological cohorts are mostly based on single-center or multi-center cases, or cohorts with limited sample size in China. There is a lack of comprehensive and large-scale prospective cohort studies in hematology. The purpose of this study is to analyze the incidence and risk factors of major blood diseases, the treatment methods, prognosis and medical expenses of these patients in China. Method The study will include patients diagnosed with acute myeloid leukemia, multiple myeloma, hemophilia, aplastic anemia, leukemia, myelodysplastic syndrome, lymphoma, bleeding disorders, autoimmune hemolytic anemia, large granular lymphocyte leukemia, essential thrombocythemia, blood infection or received bone marrow transplantation in the investigating hospitals from January 1, 2020, and collect basic information, diagnostic and treatment information, prognosis information, as well as medical expense information from medical records. In its current form, the NICHE registry incorporates historical data (collected from 2000) and is systematically collecting prospective data in two phases with broadening reach, and prospectively follow-up to collect the prognosis information.

The High-Altitude Hematology Observation-Stem Cell Transplantation (HALO-SCT) study is the first prospective real-world cohort of hematologic diseases and transplantation in the Qinghai-Tibet Plateau. Patients undergoing hematopoietic stem cell transplantation (HSCT) at Qinghai University Affiliated Hospital, together with their donors, are systematically enrolled. The registry collects demographic, diagnostic, treatment, prognosis, and medical expense information, as well as biospecimens for future analyses. Historical data are incorporated, and prospective data collection is ongoing with long-term follow-up planned. The registry is designed as a sustainable research infrastructure to provide comprehensive data on disease incidence, treatment patterns, outcomes, and resource utilization in a high-altitude setting.

The objective of this study is to evaluate whether certain proteins, expressed in biological tissues can indict a better understanding of the effect of drugs that are used to treat rejection, and of processes leading to rejection and rejection-free outcomes.

A prospective, open, randomised implementation study in paediatric cancer patients. The study aims to determine whether a personalised approach will result in an overall reduction in clinically relevant adverse drug reactions (ADRs) and to evaluate the economic and quality of life impacts. Participants will be randomised to receive personalised guided prescribing of supportive care therapy (study arm) or standard of care (control arm) for a period of 12 weeks. The follow up period includes prospective patient reporting of symptoms and quality of life through electronically delivered surveys, for a maximum of 12 months.
