Unlabelled: The aim of this study is to analyze the profile of patients receiving daratumumab and their presentation to the transfusion laboratory by looking at the different pre-transfusion policies and the risk of erythrocyte alloimmunization. Patients receiving daratumumab from 2018 to 2023 were reviewed. They were divided into two groups: Group I, presented before administration of daratumumab, and Group II, presented after drug administration.

Background And Objectives: The detection of treponemal antibodies, which are used to make a diagnosis of syphilis, is important both for diagnostic purposes and as a mandatory blood donor test in most countries. We evaluated the feasibility of using Kode Technology to make syphilis peptide red cell kodecytes for use in column agglutination serologic platforms.

Materials And Methods: Candidate Kode Technology function-spacer-lipid (FSL) constructs were made for the Treponema pallidum lipoprotein (TmpA) of T.

Autoimmune hemolytic anemia (AIHA) is a common term for several disorders that differ from one another in terms of etiology, pathogenesis, clinical features, and treatment. Management of patients with AIHA has become increasingly evidence-based in recent years. While this development has resulted in therapeutic improvements, it also carries increased requirements for optimal diagnosis using more advanced laboratory tests.

Autoimmune haemolytic anaemia (AIHA) is a common term for several disorders that differ from one another in terms of aetiology, pathogenesis, clinical features, and treatment. Therapy is becoming increasingly differentiated and evidence-based, and several new established and investigational therapeutic approaches have appeared during recent years. While this development has resulted in therapeutic improvements, it also carries increased medical and financial requirements for optimal diagnosis, subgrouping, and individualization of therapy, including the use of more advanced laboratory tests and expensive drugs.

Article Synopsis
  • The introduction of regular blood transfusions has changed thalassemia major from a deadly childhood condition to a manageable chronic disorder, particularly in South Asia where it's common.
  • In India, issues like inadequate blood supply, lack of regulations, and poor facilities for blood testing contribute to challenges in safe transfusion practices, leading to complications for patients.
  • Raising awareness, training healthcare workers, and improving resource management are crucial for enhancing transfusion safety, while new affordable treatments could lessen dependence on transfusions.

The DEL phenotype represents an intriguing and challenging aspect of blood group serology. This condition is characterized by an extremely weak expression of the D antigen on red blood cells, to the extent that it often eludes detection through routine serological methods. Identifying the DEL phenotype necessitates more specialized techniques, such as adsorption and elution tests, to reveal the presence of the D antigen.

Article Synopsis
  • The study presents a rare cis-AB blood group case in an Indian patient, marking the first molecular characterization in the Indian subcontinent.
  • Blood grouping was performed using different techniques, revealing the AB phenotype and unique agglutination reactions that aided in identification.
  • Whole exome sequencing identified two significant nucleotide changes in the ABO gene, contributing to the cis-AB phenotype, which had not been previously documented.

Patients who require blood from rare blood group donors present great challenges even to the most advanced healthcare delivery system. It is most challenging to supply blood for a patient with an antibody to an antigen of high prevalence. The blood donor lacking the corresponding antigen would have an occurrence rate of less than one in 1,000.

Tumour cells activate immune checkpoints such as programmed death receptor-1 (PD-1) and cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) signalling pathways to inhibit T lymphocyte activation and thus escape from immune surveillance. Immune checkpoint inhibitors (ICPis) reactivate T lymphocytes to recognize cancer cells by blocking CTLA-4 or PD-1. Autoimmune haemolytic anaemia is a rare, but often severe, complication of ICPis.

Autologous chimeric antigen receptor-T (CAR-T) cell therapy has proven itself as an effective therapeutic modality for cancers, especially hematological malignancies and is emerging as a potential candidate for solid organ cancers as well. However, the accessibility to treatment has been limited due to complexities and costs associated with manufacturing a genetically modified autologous product. The centralized model of CAR-T manufacturing which has emerged as the dominant model in developed nations does not seem well-suited to the needs and realities of the developing economies.

Background: Autoimmune haemolytic anaemia (AIHA) is a decompensated acquired haemolysis caused by the host's immune system acting against its own red cell antigens. The aim of this national survey is to capture real-world data of clinical practices in AIHA by collecting responses from clinical haematologists across India.

Methodology: In this cross-sectional study, a structured, 26-question online survey was conducted in India by few members of the special interest group in immunohaematology between January and March, 2022.

Transfusion related acute lung injury (TRALI) is a rare but potentially fatal pulmonary complication of transfusion that presents as acute hypoxemia and non-cardiogenic pulmonary oedema, developing during or within six hours of transfusion. Majority of the cases reported are due to transfusion of plasma rich blood components containing antibodies to human leukocyte antigen (anti-HLA) or human neutrophil antigen (anti-HNA). Rarely, anti-HLA or anti-HNA in recipients against transfused donor leukocyte antigens, cause TRALI by a reverse mechanism.

This study was conducted to determine the impact of thromboelastography (TEG) on blood transfusion policy regarding utilization and preparation of cryoprecipitate in adult cardiac surgery. The differences in total transfusion requirement, length of postoperative ICU stay and 24 h mortality were also studied after introduction of TEG in transfusion protocol. It was a retrospective, single-center, observational study conducted in adult patients underwent cardiac surgery from April 2008 to March 2016.

Polyneuropathy, Organomegaly, Endocrinopathy, M protein and Skin changes (POEMS) syndrome is rare plasma cell dyscrasia with multisystem involvement. The name comes from the five characteristic features: Polyneuropathy, organomegaly, endocrinopathy, M protein and skin changes. The presence of biclonal M band is a rare manifestation.
