Bermúdez-Forero MI, García-Otálora MA. Blood transfusion dynamics in Colombia: Unveiling patterns, reactions and survival rates in multitransfused patients. Vox Sang 2024. [PMID: 38922908 DOI: 10.1111/vox.13700] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2024] [Revised: 06/05/2024] [Accepted: 06/06/2024] [Indexed: 06/28/2024]
Abstract
BACKGROUND AND OBJECTIVES There is no consensus on a universally accepted threshold to categorize a patient as multitransfused. In 2019, Colombia established the definition of a multitransfused patient as someone who has received six or more blood components, irrespective of the time frame. This study aims to delineate the characteristics, adverse transfusion reactions (ATRs, definitions according to the International Society of Blood Transfusion [ISBT]) and survival rates in this population. MATERIALS AND METHODS We performed an analysis from the data of all institutions engaged in blood component transfusions at the national level who notified events to the National Information System of Haemovigilance (SIHEVI-INS), from January 2018 to December 2022. The selection criteria focused on individuals who not only exhibited ATRs but also received six or more blood components. RESULTS Among the 1,784,428 patients who received 6,637,271 blood components, an average of 3.7 components per patient was noted. Concurrently, 8378 ATRs were reported (12.6 ATRs/10,000 transfused components). Within this cohort, 691 patients met the criteria for multitransfusion. Predominantly women (51.8%), these individuals received between 6 and 14 blood components. Out of the 691 multitransfused individuals who experienced ATR, 541 had an allergic reaction. Conversely, out of the 6479 non-multitransfused individuals who experienced ATR, 3835 had an allergic reaction (odds ratio: 2.49, 95% confidence interval: 2.06-3.0). Notably, 271 multitransfused individuals (39.2%) were documented as deceased, with 76% succumbing within 12 months of encountering their most recent ATR. CONCLUSION Multitransfused individuals in Colombia, being a high-risk group, exhibit a heightened susceptibility to allergic reactions, surpassing the frequency observed in other transfusion populations. This underscores the necessity for tailored medical care specific to this group.

Alloimmunization Against RBC Antigens Is Not Associated With Decreased Survival in Liver Transplant Recipients. Am J Clin Pathol 2023; 159:255-262. [PMID: 36626677 DOI: 10.1093/ajcp/aqac150] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2022] [Accepted: 10/25/2022] [Indexed: 01/11/2023] Open
Abstract
BACKGROUND Improvement of liver transplantation (LT) outcomes requires better understanding of factors affecting survival. The presence of RBC alloantibodies (RBCAs) on survival in LT recipients was evaluated. METHODS This study was a single-center, retrospective cohort study reviewing transfusion records and all-cause mortality between 2002 and 2021. RESULTS Between 2002 and 2021, 2079 LTs were completed, 1,396 of which met inclusion criteria (1,305 RBCA negative; 91 RBCA positive [6.5%]). The cohorts were similar in age (mean [range], 55.8 [17-79] years vs 56.8 [25-73] years; P = .41, respectively) or sex (RBCA negative, 859 [65%] men and 446 [35%] women vs RBCA positive, 51 [56%] men and 40 [44%] women; P = .0684). Of 132 RBCAs detected, 10 were most common were to E (27.27%), Jka (15.91%), K (9.09%), C (8.33%), M (6.06%), D (5.3%), Fya (4.55%), e (2.27%), c (2.27%), and Jkb (2.27%). Twenty-seven patients (29.7%) had more than 1 RBCA; the most common combinations were C with Jka (7.4%) and E with Dia (7.4%). All-cause mortality was increased in men (men, 14.45 years vs women, 17.27 years; P = .0266) and patients 65 years of age and older (≥65 years of age, 10.21 years vs <64 years of age, 17.22 years; P < .0001). The presence of RBCA (≥1) did not affect all-cause mortality (RBCA negative, 14.17 years vs RBCA positive, 15.29 years; P = .4367). The top 5 causes of death were infection (11.9%), primary malignancy (solid) (10.8%), recurrent malignancy (10.5%), cardiovascular arrest (7.1%), and pulmonary insufficiency/respiratory failure (5.7%). CONCLUSIONS Survival in RBCA-positive LT recipients is no different from that in RBCA-negative LT recipients.

Red Blood Cell Alloimmunization and Its Associated Factors among Chronic Liver Disease Patients in a Teaching Hospital in Northeastern Malaysia. Diagnostics (Basel) 2023; 13:diagnostics13050886. [PMID: 36900030 PMCID: PMC10001194 DOI: 10.3390/diagnostics13050886] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 02/16/2023] [Accepted: 02/16/2023] [Indexed: 03/02/2023] Open
Abstract
Red blood cell (RBC) alloimmunization is an important complication of blood transfusion. Variations in the frequency of alloimmunization have been noted among different patient populations. We aimed to determine the prevalence of RBC alloimmunization and associated factors among chronic liver disease (CLD) patients in our center. This is a case-control study involving 441 patients with CLD who were being treated at Hospital Universiti Sains Malaysia and subjected to pre-transfusion testing from April 2012 until April 2022. Clinical and laboratory data were retrieved and statistically analyzed. A total of 441 CLD patients were included in our study, with the majority being elderly, with the mean age of patients 57.9 (SD ± 12.1) years old, male (65.1%) and Malays (92.1%). The most common causes of CLD in our center are viral hepatitis (62.1%) and metabolic liver disease (25.4%). Twenty-four patients were reported to have RBC alloimmunization, resulting in an overall prevalence of 5.4%. Higher rates of alloimmunization were seen in females (7.1%) and patients with autoimmune hepatitis (11.1%). Most patients developed a single alloantibody (83.3%). The most common alloantibody identified belonged to the Rh blood group, anti-E (35.7%) and anti-c (14.3%), followed by the MNS blood group, anti-Mia (17.9%). There was no significant factor association of RBC alloimmunization among CLD patients identified. Our center has a low prevalence of RBC alloimmunization among CLD patients. However, the majority of them developed clinically significant RBC alloantibodies, mostly from the Rh blood group. Therefore, phenotype matching for Rh blood groups should be provided for CLD patients requiring blood transfusions in our center to prevent RBC alloimmunization.

Pandey P, Setya D, Ranjan S, Singh MK. An assessment of clinical and laboratory impact in a resource constraint setting: Does Rh and Kell phenotyping of donor units complement type and screen method of compatibility testing? Transfus Clin Biol 2023; 30:219-227. [PMID: 36608866 DOI: 10.1016/j.tracli.2022.12.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2022] [Revised: 12/26/2022] [Accepted: 12/28/2022] [Indexed: 01/05/2023]
Abstract
BACKGROUND AND AIM Despite knowing benefits of extended phenotyping, a vast majority feel that phenotype matched units add to the cost of blood banking. The purpose of this study was to discuss advantages and disadvantages of performing Rh Kell phenotyping in Indian scenario. MATERIALS AND METHODS This was a prospective, observational study conducted at a tertiary healthcare center between July 2014 and February 2020. All consecutive whole blood donors and all consecutive patients whose samples were sent for Rh-Kell phenotyping were included for calculating antigen, phenotype and gene frequencies. For rate of alloimmunization in patients transfused with phenotype matched units, all patients who were given Rh-Kell phenotype matched transfusions were included in the prophylactic antigen matched (PAM) category and those who were given random units were included in the non-PAM category. RESULTS A total of 37,588 donors and 258 patients were included in the study for calculation of antigen, phenotype and gene frequencies. Percentage similarity of phenotypes between patient and donor populations was 33.8%. For rate of alloimmunization, results of a total of 31,991 patient samples revealed 0.94% prevalence of unexpected antibodies; highest against the Rh system. Three patients in the non-PAM category and one in the PAM category were alloimmunized during follow-up. Significant clinical and laboratory impact of phenotyping was observed in terms of reduced turnaround time and consumption of resources. CONCLUSION Rh-Kell phenotyping of donors can prevent alloimmunization, reduce cost burden on the patient and the laboratory and help the laboratory personnel in smooth routine testing.

Vox Sang 2022; 117:1057-1069. [PMID: 35608911 DOI: 10.1111/vox.13296] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Revised: 03/23/2022] [Accepted: 04/14/2022] [Indexed: 11/27/2022]
Abstract
BACKGROUND AND OBJECTIVES There is a varied prevalence of red cell alloimmunization being reported from different parts of India. This study aimed to estimate the overall prevalence of alloimmunization in India by performing a systematic review of the literature and to establish the most suitable antigen-matching strategy to reduce the red blood cell (RBC) alloimmunization rate among transfusion recipients. MATERIALS AND METHODS A systematic search of all the original articles published in English on RBC alloimmunization among transfusion recipients from India in MEDLINE, SCOPUS, CINAHL and Google Scholar bibliographic databases was conducted. After screening the articles as per inclusion/exclusion criteria, data extraction was done independently by two sets of investigators. Meta-analysis was performed by the binary random-effects model using the restricted maximum likelihood method. RESULTS A total of 44 studies on RBC alloimmunization, with a cumulative sample size of 309,986 patients, were grouped into hospital-based and multiply-transfused patients, which yielded a prevalence of 0.5 (95% confidence interval; 0.3-0.8) and 4.8 (95% confidence interval; 3.9-5.7) per 100 patients, respectively. As many as 1992 alloantibodies were identified among the 1846 alloimmunized patients. The most common antibody identified was anti-E (127; 31.99%), followed by anti-c (75; 18.89%) in multiply-transfused patients. CONCLUSION The rate of alloimmunization was 0.5 per 100 patients tested for antibodies and 4.8 per 100 patients receiving transfusion. Considering E- and c-antigen-matched red cells along with ABO and RhD matching may significantly reduce the overall occurrence of alloimmunization among Indian population who are transfusion-dependent.

Abstract
Red blood cell (RBC) alloimmunization varies across human populations and ethnic groups. We evaluated the characteristics of RBC alloimmunization and compared the risk of alloimmunization in Korean patients with myelodysplastic syndrome (MDS) and liver cirrhosis (LC), two representative diseases in which chronic transfusion is required. In total, 115 MDS patients and 202 LC patients transfused with RBCs between 2013 and 2015 were retrospectively included. Twenty patients (6.3%) were newly alloimmunized (five MDS patients, 4.3%; 15 LC patients, 7.4%). The median number of RBC units transfused in alloimmunized patients was nine (interquartile range, 4–15 units). As the number of transfused RBC units increased, the cumulative risk of alloimmunization was higher in LC than in MDS patients (P=0.001). The most common alloantibody detected in patients was anti-E (45%), followed by anti-c (17%), anti-e (10%), anti-C (7%), anti-Fyb (7%), and anti-Jka (7%). The present data indicate the need for matching of extended RBC antigens (Rh, Duffy, and Kidd systems) for chronically transfused patients with MDS and LC in Korea.
