Abstract
The development of intravenous IgG (IVIG) formulations in the 1970s enabled expanded use for treating primary antibody deficiency syndromes and autoimmune conditions. Recent advancements include the use of IVIG in secondary immune deficiencies related to hematologic malignancies and stem cell transplantation, along with the newly emerging prophylactic applications following chimeric antigen receptor T-cell (CAR-T) therapies. Novel therapeutic areas such as bispecific antibodies (BsAbs) for lymphoma and myeloma have increased the use of IgG, given the associated risks of infections. Today, the concept of a rational personalized clinical use of IgG in the context of evolving clinical indications in high-income countries (HIC) is emerging, as unmet challenges in line with managing shortages due to increasing demands globally. The current work aims to review and link the indications for IgG to their characteristics and formulations, their dose, route and frequency of administrations and duration of therapy to meet the needs of individual patients. It will also explore the means to rationalize and monitor IgG use in HIC in the time of shortage, while explaining pragmatic strategies to improve supply and use in low- and middle-income countries (LMIC).
期刊介绍：
Transfusion and Apheresis Science brings comprehensive and up-to-date information to physicians and health care professionals involved in the rapidly changing fields of transfusion medicine, hemostasis and apheresis. The journal presents original articles relating to scientific and clinical studies in the areas of immunohematology, transfusion practice, bleeding and thrombotic disorders and both therapeutic and donor apheresis including hematopoietic stem cells. Topics covered include the collection and processing of blood, compatibility testing and guidelines for the use of blood products, as well as screening for and transmission of blood-borne diseases. All areas of apheresis - therapeutic and collection - are also addressed. We would like to specifically encourage allied health professionals in this area to submit manuscripts that relate to improved patient and donor care, technical aspects and educational issues.
Transfusion and Apheresis Science features a "Theme" section which includes, in each issue, a group of papers designed to review a specific topic of current importance in transfusion and hemostasis for the discussion of topical issues specific to apheresis and focuses on the operators'' viewpoint. Another section is "What''s Happening" which provides informal reporting of activities in the field. In addition, brief case reports and Letters to the Editor, as well as reviews of meetings and events of general interest, and a listing of recent patents make the journal a complete source of information for practitioners of transfusion, hemostasis and apheresis science. Immediate dissemination of important information is ensured by the commitment of Transfusion and Apheresis Science to rapid publication of both symposia and submitted papers.
