A retrospective analysis of autoimmune hemolytic anemia after allogeneic hematopoietic stem cell transplantation for transfusion-dependent β-thalassemia: focus on T and B lymphocyte reconstitution.
Ann Hematol
January 2025
Department of Hematology, The First Affiliated Hospital of Wenzhou Medical University, Wenzhou, 325035, China.
Background: Autoimmune hemolytic anemia (AIHA) following allogeneic hematopoietic stem cell transplantation (allo-HSCT) is often refractory and relapsing, leading to increased mortality post-HSCT.
Methods: We retrospectively analyzed the cases of patients with transfusion-dependent β-thalassemia (TDT) who underwent allo-HSCT to study their clinical features, the occurrence of AIHA post-HSCT, and treatment response and to explore the possible pathogenesis of AIHA.
Result: A total of 113 patients were registered in the study, out of whom 14 developed AIHA following allo-HSCT, resulting in a cumulative incidence of 12.
Joint effects of atrial fibrillation and prothrombotic genotypes on the risk of ischemic stroke.
J Thromb Haemost
December 2024
Thrombosis Research Group, Department of Clinical Medicine, UiT The Arctic University of North Norway, Tromsø,Norway; Division of Internal Medicine, University Hospital of North Norway, Tromsø, Norway.
Background: Atrial fibrillation (AF) is a major risk factor for ischemic stroke. Whether prothrombotic single nucleotide polymorphisms (SNPs) impact stroke risk in AF is not well known.
Objectives: To investigate the joint effects of five prothrombotic SNPs and AF on ischemic stroke risk.
[The Value of IgG Anti-A/Anti-B Antibody Titers after Absorption of IgG Anti-AB Antibodies in Predicting ABO Fetal Neonatal Hemolytic Disease].
Zhongguo Shi Yan Xue Ye Xue Za Zhi
December 2024
Department of Blood Transfusion， The Fifth Medical Center of PLA General Hospital, Beijing 100071, China.
Objective: To analyze the diagnostic value of IgG anti-A/anti-B antibody titer in the serum of type O pregnant women after absorption of IgG anti-AB antibody for ABO hemolytic disease of fetus and newborn (ABO-HDFN).
Methods: From February 2020 to September 2020, 235 samples of neonatal hemolytic disease whose mother's blood type O from Beijing Blood Center were selected. The titer of IgG anti-A/anti-B antibody in mother's serum before and after absorption of IgG anti -AB antibody was detected by microcolumn gel card, and the incidence of ABO-HDFN was statistically analyzed.
[Study on the Production of Anti-D and Anti-E Mixed Antibodies by Alloimmunization in RhD Variant Type33 Recipients].
Zhongguo Shi Yan Xue Ye Xue Za Zhi
December 2024
Blood Group Reference Laboratory, Ningxia Blood Center, Yinchuan 750000, Ningxia Hui Autonomous Region, China.
Objective: To investigate the cause of the production of anti-D and anti-E mixed antibody in an RhD positive patient.
Methods: The ABO/Rh blood group typing and irregular antibody specificity were identified by conventional serological methods, the gene exon 1-10 and heterozygous analysis were performed by sequence-specific primer polymerase chain reaction (PCR-SSP), and the whole exon sequence was analyzed by first-generation sequencing.
Results: The patient's Rh blood group was weak D Type33, with the allele was , the patients was found to be heterozygous, with an Rh typing of Ccee, and the patient had developed anti-D combined with anti-E mixed antibodies.
[Detection and Treatment for Hemolytic Transfusion Reaction in Patient with Combined Antibody Consisted of Anti-Fy and Anti-Jk].
Zhongguo Shi Yan Xue Ye Xue Za Zhi
December 2024
Department of Blood Transfusion, Renji Hospital, Shanghai Jiaotong University School of Medicine, Shanghai 200127, China.
Objective: To investigate and assess hemolytic transfusion reaction in patient with complex and combined anti-Fy and anti-Jk which so as to provide a safety blood transfusion strategy.
Methods: ABO/Rh blood grouping, antibody screening and identification, and Coombs' tests were performed by the routine serological methods include manual tube and automatic blood group analyzer with matching micro-column gel cards from Diagnostic Grifols and Jiangsu LIBO. The hospital information system and laboratory information system were used to collect dada on patients' blood routine tests, liver and kidney function, coagulation, cardiac function, and other clinical indicators before and after blood transfusion were analyzed and compared in conjunction with the patients' clinical manifestations.
