Research progress of SMIM1 in Vel blood type, tumor and plasmodium infection / 中国输血杂志

Small integral membrane protein 1(SMIM1) gene encodes Vel blood group antigen, and homozygous deletion of 17 bases pairs in its exon 3 leads to Vel negative phenotype. As a rare phenotype, accurate identification and prevention of transfusion reaction for Vel negative phenotype is particularly important. In addition to serving as a Vel blood group antigen, recent bioinformatics analysis suggests that SMIM1 protein may be a new tumor biomarker involved in the occurrence and development of numerous tumors. Due to the similarity in structure between SMIM1 protein and glycoprotein, and its phosphorylation in red blood cells infected with Plasmodium falciparum, it is speculated that SMIM1 protein may be involved in the development of malaria. Therefore, this article provides a review of the related research on SMIM1 and its coding protein in Vel blood type, tumor and plasmodium infection.

Chimeric antigen receptor T-associated cytokines release syndrome managed by therapeutic plasma exchange and tumor necrosis factor inhibitors: a case report / 中国输血杂志

【Objective】 To learn more about the role of therapeutic plasma exchange in the management of cytokines release syndrome(CRS) after chimeric antigen receptor T(CAR-T) infusion by reviewing and analyzing the diagnosis and treatment of one case. 【Methods】 The diagnosis and treatment of lymphoma patients with CAR-T infusion related CRS were described, and case analysis was carried out by searching PubMed, Elsevier, Wiley, CNKI, and other databases for relevant guidelines, clinical trials, and case reports. 【Results】 The patient was diagnosed with follicular cell lymphoma. Progressive disease(PD) was assessed after multiple courses of treatment, and anti-CD19/20 CAR-T cell therapy was administered.The patient developed a high fever and chills, secondary dyspnea and hypotension at night on the day of infusion, and the inflammatory factors such as C-reactive protein(CRP) and interleukin-6(IL-6) increased sharply, suggesting the occurrence of cytokines release syndrome(CRS). After the patient was given symptomatic antipyretic, broad-spectrum anti-infection, tumor necrosis factor(TNF) antibody and three occasions of plasma exchange, the clinical manifestations of CRS gradually relieved. Three months after discharge, the patient was in complete response(CR). 【Conclusion】 CAR-T-associated CRS is a serious cellular immunotherapy-related toxicity that can result in multiple organ failure or even death in patients. Therapeutic plasma exchange may be a potential treatment for some patients with severe CRS.

Serological and molecular biological analysis of an individual with para-Bombay blood group due to homozygous c.948C>A variant of FUT1 gene / 中华医学遗传学杂志

OBJECTIVE@#To study the serological, molecular and genetic characteristics of an individual with para-Bombay blood group.@*METHODS@#Serological method was used to detect the presence of A, B, H antigens in red blood cells and saliva, and Sanger sequencing was used to analyze the FUT1 gene of the proband and her family members. Genetic mechanism of the blood group was analyzed by pedigree analysis.@*RESULTS@#Forward and reverse typing of the ABO blood group were inconsistent for the proband. A, B and H antigens were not found on erythrocytes, while B and H antigens were found in saliva, in addition with unexpected antibodies. The proband was found to have a genotype of ABO*B.01/ABO*O.01.04 caused by homozygous variant of c.948C>A (p.Tyr316Ter) of the FUT1 gene.@*CONCLUSION@#A novel para-Bombay blood group was identified, which was due to the missense variant of c.948C>A in the coding region of the FUT1 gene, which has probably resulted in inability to synthesis active H antigen transferase.

Among them, 1 was B(A)04/O1 type, and 4 were B(A)04/B type. The primary blood matching of B(A) blood type samples with type B and O recipients were all negative. 【Conclusion】 A total of 5 cases of B(A)04 blood type were found in this family investigation, and there were differences in serological manifestations. Washed RBCs with B and O type can be used for B(A) blood type transfusion, and type B suspended RBCs can be considered in case of emergency.

Exploring the impact of ABO blood group on the outcomes of allogeneic hematopoietic cell transplantation / 中国输血杂志

【Objective】 To investigate the impact of ABO blood group compatibility and incompatibility(major /minor/bidirectional incompatibility) on the outcomes of patients underwent allogeneic hematopoietic stem cell transplantation(allo-HSCT), and to provide evidences for optimizing the transplantation program. 【Methods】 From January 2014 to June 2018, we retrospectively reviewed the clinical courses of 18 recipients of allo-HSCT from ABO-compatible donors and 52 from ABO-incompatible donors at our hospital. The implantation time of granulocyte/erythrocyte/megakaryoblast, RBC/platelet transfusions within 3 months posttransplantation, the initiating and completion time of ABO blood group conversion(for ABO-compatible donors only) were analyzed and compared among the ABO-incompatible and ABO-compatible donors as such variables including demographic data, donor and patient relationship, diagnosis of disease, bone marrow hematopoietic function prior to transplantation, HLA matching were not significant different. 【Results】 For 18 recipients of allo-HSCT from ABO-compatible donors, the implantation time of granulocyte, erythrocyte, megakaryoblast was 12.0(11.0~16.3), 41.5 (35.0~49.0) and 19.0(16.0~22.5)days, respectively. For 52 recipients of allo-HSCT from ABO-incompatible donors, the ABO blood group conversion was initiated at 28.0(22.5~44.0)days posttransplantation and completed at 105.5(85.0~141.8)days. In the ABO-compatible group, the time of erythrocyte implantation was shortened(P0.05), no significant difference was observed between these two variables. The blood group conversion time, implantation time of granulocyte/erythrocyte/megakaryoblast, and RBC /platelet transfusions among ABO major, minor and bidirectional incompatible groups were not significant different (P>0.05). 【Conclusion】 ABO-compatiblity enjoys priority in allo-HSCT. ABO-incompatiblity can be chosen in the order of minor, major and bidirectional incompatibility in the absence of ABO-compatiblity.

Interference of CD38 monoclonal antibody in blood compatibility testing and its countermeasures: A general consensus among experts / 中国输血杂志

With continuous discovery of tumor immune targets and continuous changes in antibody research and development technology, antibody drugs are becoming more and more widely used in clinical practice. However, some targets are not only expressed on tumor cells, but also on red blood cells. Therefore, the clinical application of antibodies against the corresponding targets may interfere with the detection of blood transfusion compatibility, resulting in difficulty in blood matching or delay of blood transfusion. This consensus summarizes the current solutions for the interference of CD38 monoclonal antibody (CD38 mAb) in transfusion compatibility testing. After analyzing the advantages and disadvantages of different methods, polybrene and sulfhydryl reducing agents [dithiothreitol (DTT) or 2-mercaptoethanol (2-Me)], as a solution for CD38 mAb interference in blood compatibility testing, are recommended for Chinese patients, so as to eliminate blood transfusion interference produce by CD38 mAb and further provide a pre-transfusion workflow for clinicians and technicians in Department of Blood Transfusion.

【Objective】 To investigate the preoperative anemia and perioperative blood transfusion in patients with duodenal papillary carcinoma who underwent Whipple surgery. 【Methods】 The clinical data of 1 959 cases with duodenal papillary carcinoma, subjected to Whipple surgery, were retrospectively analyzed. 【Results】 The rate of anemia in preoperative patients with duodenal papillary carcinoma was 54.87%(1 075/1 959). The incidence rate of anemia in the three age groups from low to high was 44.92% (≤50 years old, 190/423), 52.82% (51~64 years old, 506/958), and 65.57% (≥65 years old, 379/578) (P<0.05), and the highest rate of anemia occurred in patients aged above 65. There was a significant statistical difference among patients with different body mass index (BMI)(P<0.05). Patients with moderate or severe anemia received more red blood cells than patients with mild anemia during the perioperative period (P<0.05). The average hospitalization time of the blood transfusion patients was 27.25 days, and that of non-transfusion patients was 22.22 days (P<0.05). The amount of blood loss and hospitalization time of patients underwent laparoscopic and robotic surgery were significantly lower than those underwent open surgery patients (P <0.05). There were only 24.09%(186/772) treated with drugs for anemia intervention and the majority of patients (75.91%, 586/772) were treated with blood transfusions to interfere with anemia during hospitalization. 【Conclusion】 There are significant differences in the incidence rate of preoperative anemia among patients with duodenal papillary carcinoma who undergone Whipple surgery. Low BMI, abnormal WBC, and perioperative blood transfusion are high-risk factors for prolonged hospital stay, whereas anemia is not associated with prolonged hospital stay.
