Filter by:Autoimmune hemolytic anemia (AIHA) is a rare and heterogeneous disorder characterized by the destruction of red blood cells through warm or cold antibodies. Glucocorticoid (combined with rituximab) is the first-line treatment. However, the recurrence rate is very high and some patients may not respond to steroids. Second-line therapies include cyclosporine A (CsA), cyclophosphamide, rituximab, azathioprine, and even splenectomy. Our previous study of sirolimus in refractory/relapsed AIHA and ES found an effective rate of 80%. Therefore, the investigators plan to explore the efficacy and safety of sirolimus in the treatment of refractory/relapsed wAIHA.

Bruton's tyrosine kinase (BTK) plays a crucial role in the signaling pathway of B-cell receptor (BCR), and has been found to be a major source of pathogenic signal transduction for various lymphoproliferative malignancies. The activity of BTK is related to the occurrence and progression of various B-cell lymphomas. Currently, BTK inhibitors are widely used in the treatment of B-cell lymphomas, including chronic lymphocytic leukemia (CLL), mantle cell lymphoma (MCL), Waldenstrom's macroglobulinemia (WM), and other B-cell lymphomas, showing significant efficacy. BTK affects the production of messenger molecules and regulates the BCR signaling pathway, causing B cells to transform into self-reactive B cells, which can trigger autoimmune diseases. Current research has shown that BTK activity increases in several autoimmune diseases, including systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) . Therefore, BTK inhibitors (BTKi) are important for the treatment of autoimmune diseases. Ibrutinib, one kind of BTKi, has been proven to treat secondary autoimmune hemolytic anemia (AIHA) in CLL and control CLL progression, and is an effective drug for treating lymphoma-associated AIHA . One kind of second-generation selective BTKi, acalabrutinib, can also reduce the incidence of AIHA in relapsed or refractory CLL patients. Currently, phase-II clinical studies exploring the treatment of AIHA using Ibrutinib, acalabrutinib, and rilzabrutinib, another BTKi, are underway. Zanubrutinib (BGB-3111, Brukinsa®, BeiGene) is a second-generation irreversible BTKi developed by Chinese company BeiGene. Compared to Ibrutinib, zanubrutinib has shown stronger effective activity and higher selectivity towards BTK, and weaker effects on other targets such as TEC, EGFR, and Src families, with low off-target side effects. Its efficacy, durability, oral absorption, and targeting are better than those of Ibrutinib. Zanubrutinib is approved for the treatment of various B-cell lymphomas, and clinical trials have shown excellent efficacy and tolerability in CLL and WM patients. In previously treated CLL patients, zanubrutinib exhibits better efficacy and safety than Ibrutinib. Currently, phase II clinical studies of zanubrutinib in ITP, antiphospholipid syndrome, IgG4-related immune diseases, and active proliferative lupus nephritis are underway. The therapeutic effect of zanubrutinib on refractory warm autoimmune hemolytic anemia, is worth exploring through exploratory research.
The purpose of this study is to assess the effectiveness of nipocalimab when compared to placebo in decreasing the risk of fetal anemia (a condition in which a baby's red blood cell volume falls below normal levels while the baby is developing in the womb) with live neonates in pregnant participants at risk for severe hemolytic disease of the fetus and newborn.
This is a Phase 3b, open-label, single-arm, multicenter study to evaluate the efficacy and safety of eculizumab in participants with atypical hemolytic uremic syndrome (aHUS) in China
To analyze the dietary nutrition and dietary fiber (DF) intake of maintenance hemodialysis (MHD) patients, and explore the effect of dietary nutrition and DF intake balance on the nutritional status and pre-dialysis hyperkalemia of MHD patients.
A prospective observational cohort study was designed. 1. Comparing of the clinical indicators between the hemolytic group and the non-hemolytic group,such as End-tidal carbon monoxide corrected for ambient CO(ETCOc),direct antiglobulin test(DAT), the highest total serum bilirubin level and hemoglobin. To explore the role of ETCOc in the diagnosis of neonatal ABO hemolytic disease. 2. Comparing of the clinical indicators between the neonates with IVIG treatment and the neonates without IVIG treatment in ABO hemolytic disease, such as ETCOc,total serum bilirubin level before IVIG treatment and ETCOc,total serum bilirubin level after IVIG treatment.To explore the clinical value of ETCOc in the treatment of ABO hemolytic disease.
This study aims to explore whether an 8-week Triflow breath training program reduced the anxiety levels and improved the heart rate variability and quality of life of patients receiving hemodialysis. To investigate the effect of the triflow respiration training on the improvement of heart rate variability, anxiety, and the quality of life in hemodialysis patients.
Hemolytic Uremic Syndrome (HUS) is a rare disease characterized by rupture of red blood cells (hemolytic anemia), low platelet count (thrombocytopenia), and thrombotic occlusion of small vessels (thrombotic microangiopathy), with prevalent involvement of the kidneys. SEU, in its typical form is caused by gastrointestinal infection with Escherichia coli. The atypical form of SEU (aSEU), which is not caused by an Escherichia coli infection, is a very rare disease that may have a genetic origin; it affects both children and adults and may occur in a sporadic or familial form. Many studies have shown that about 60% of cases of atypical HUS are associated with genetic abnormalities of the complement system (particularly the so-called "alternative pathway"), which is a key part of the immune system for responding to infection. Complement consists of a series of proteins that, when activated, create a so-called "cascade," which leads to the elimination of the infectious agent, either directly or through other cells. Complement is finely regulated in such a way as to prevent damage to healthy cells in one's own body. Genetic defects in some of these complement regulatory proteins cause reduced protection of the endothelial surface (thus the vessel wall) against complement activation. Recently, new mutations have been described in a gene unrelated to the complement pathway, the DKGE gene, which codes for the intracellular isoform of diacylglycerol kinase . In these patients, small renal vessel occlusion appears to occur as a result of altered endothelial cell proliferation and angiogenesis through mechanisms apparently unrelated to complement activation. However, to date these mechanisms are poorly studied. Throughout the entire project statistical methods will be applied to optimize the characterization of the abnormalities in phenotype and function of iPSC-EC derived from aHUS patients with either DGKE or MCP genetic abnormalities as compared with control iPSC-EC, including identifying potential drugs that could correct the abnormalities
This is a multicenter, single arm, open-label, extension study to evaluate the long-term safety, tolerability, and efficacy of iptacopan in participants with aHUS.
