Prevalence of dog erythrocyte antigen (DEA) 1 amongst the dog blood donors at Tamil Nadu veterinary and animal sciences university animal blood bank (TABB), India

The blood group antigen Dog Erythrocyte Antigen (DEA) 1.1 is clinically the most important canine blood group as DEA 1.1 antibodies are capable of causing acute haemolytic, potentially life-threatening transfusion reactions. Dogs do not have naturally occurring antibodies to DEA 1.1 but are rapidly sensitised by the first incompatible transfusion. The prevalence of DEA 1.1 in the general dog population is estimated at 42-46 %. Canine blood donors registered with the Onderstepoort Animal Blood Bank (n = 93) as well as potential donors (n = 140) were typed for DEA 1.1 using a monoclonal antibody card kit. All dogs came from the Onderstepoort area, near Pretoria, Gauteng province, South Africa. Overall prevalence of DEA 1.1 was 47 %. Prevalence was 47 % in purebred dogs and 48 % in mongrels. Distinct breed differences were noted with less than 20 % of German shepherd dogs and Boxers and greater than 75 % of Rottweilers, Great Danes, St Bernards and Dalmations testing DEA 1.1 positive. Knowledge of local breed differences will increase effectiveness of blood donor recruitment.

Dog Erythrocyte

Galgos (Spanish Greyhounds), in common with other sighthounds, have higher hematocrits, hemoglobin concentrations, and red blood cell counts than other breeds. In addition to these hematological characteristics, the physical characteristics of these dogs (medium to large dogs with an easily accessible jugular vein and a good temperament) make galgos ideal blood donors. However, to date, there are only published reports concerning dog erythrocyte antigen (DEA) 1 in this breed. Information on DEAs 4 and 7 would be useful when recruiting blood donors to donation programs, as DEA 1 and 7–negative and DEA 4–positive dogs can be considered universal donors. Ethylenediamine tetra-acetic acid–anticoagulated jugular blood samples were collected from 205 galgos. Dogs were aged between 1 and 10 years, 102 were female (49.8%) and 103 male (50.2%), and all were living in South Madrid, Spain. All 205 blood samples were tested for DEA 1 by card agglutination, and 150 of these samples were tested for DEA 4 and DEA 7 by gel column agglutination using polyclonal anti-DEA antibodies. Of the 205 galgos blood samples typed, 112 out of 205 (54.6%) were positive for DEA 1. Of the 150 blood samples tested, all (150/150, 100%) were positive for DEA 4, and 12 out of 150 (8%) samples tested positive for DEA 7. Of these samples, 70 out of 150 (46.7%) were positive only for DEA 4. There was no relationship between blood types and sex. In addition to the hematological characteristics previously reported and the physical characteristics of these dogs, the relative prevalence of blood types DEA 1, 4, and 7 make galgos good candidates for blood donation in blood donor programs.

INTRODUCTION: India being the second highly populated nation in the world. HIV/AIDS has acquired pandemic proportion in the world. Estimate by WHO for current infection rate in Asia. India has the third largest HIV epidemic in the world. HIV prevalence in the age group 15-49 yrs was an estimate of 0.2%. India has been classified as an intermediate in the Hepatitis B Virus (HBV) endemic (HBsAg carriage 2-7%) zone with the second largest global pool of chronic HBV infections. Safety assessment of the blood supply, the quality of screening measures and the risk of transfusion transmitted infectious diseases (TTIs) in any country can be estimated by scrutinizing the files of blood donors. After the introduction of the blood banks and improved storage facilities, it became more extensively used. Blood is one of the major sources of TTIs like hepatitis B, hepatitis C, HIV, syphilis, and many other blood borne diseases. Disclosure of these threats brought a dramatic change in attitude of physicians and patients about blood transfusion. The objective of this study is to determine the seroprevalence of transfusion transmitted infections amidst voluntary blood donors at a rural tertiary healthcare teaching hospital in Chhattisgarh. MATERIAL AND METHODS: This retrospective study was carried out in Chandulal Chandrakar Memorial Medical College, Kachandur, Durg. Blood donors were volunteers, or and commercial donors who donated the blood and paid by patients, their families, or friends to replace blood used or expected to be used for patients from the blood bank of the hospital. After proper donation of blood routine screening of blood was carried out according to standard protocol. Laboratory diagnosis of HIV 1 and HIV 2 was carried out by ELISA test. Hepatitis B surface antigen was screened by using ELISA. RESULTS: A total of 1915 consecutive blood donors’ sera were screened at Chandulal Chandrakar Memorial Medical College, blood bank during study period. Of these 1914 were male and 1 female. The mean age of patients was found to be 29.34 years with standard deviation (SD) of 11.65 Years. Among all blood donors in present study, 759(39.63%) were first time donors and 1156(60.37%) were repeated donors. 1 patient was HIV positive in first donation group while 3 (75%) were positive in repeat donation group. 7 (38.9%) were HBsAg positive in in first donation group while 11(61.1%) were positive in repeat donation group. Two patients in first donation group had dual infection of HIV and HBsAg. CONCLUSION: Seropositivity was high in repeated donors as compared to first time donors. The incidence of HIV is observed to be 0.2% and that of HBsAg is 0.94%. Strict selection of blood donors should be done to avoid transfusion-transmissible infections during the window period.

Objectives This article aims to analyse the safety of feline blood donation by describing the frequency and nature of any adverse reactions and their causes, as well as propose measures to decrease the incidence of adverse reactions. Methods In this prospective study, any blood donor adverse reactions detected by the clinical staff during and immediately after donation were recorded. The owners of the cats were also surveyed by a veterinary practitioner or veterinary nurse 5 days after donation, using a predefined questionnaire to assess for any clinical or behavioural changes. Data were collected between January 2019 and March 2020 from blood donors enrolled in an animal blood bank programme. Results Of 3690 blood donations from 1792 feline donors assessed, post-donation reactions were reported in 1.14% (n = 42): 0.22% (n = 8) were acute reactions, which included weakness, pallor, tachypnoea and open-mouth breathing; and 0.92% (n = 34) were delayed post-donation reactions, with 0.16% involving cutaneous (haematomas and skin rashes, n = 6), 0.68% involving behavioural (n = 25) and 0.08% involving digestive (emesis and inappetence, n = 3) signs. Conclusions and relevance The low incidence of post-donation reactions in this study is encouraging, suggesting that a well-established protocol and competent staff can help to ensure a high level of safety in a feline donor programme and, in turn, increase the confidence of cat owners.
