Distribution of ABO and Rh-D blood groups in the Benin area of Niger-Delta: Implication for regional blood transfusion
Mathew Ebose Enosolease, Godwin Nosa Bazuaye
January-June 2008, 2(1):3-5
ABO and Rhesus (Rh) blood group antigens are hereditary characters and are useful in population genetic studies, in resolving medico-legal issues and more importantly in compatibility test in blood transfusion practice. Data on frequency distribution of ABO and Rh-D in Niger-Delta region of Nigeria are not available; hence we made an attempt to retrospectively analyze the records on the blood donors, transfusion recipients and patients attending antenatal care or some other medical interventions. Over a twenty-year period between 1986 and 2005, a total of 160,431 blood samples were grouped for ABO and Rh-D at the blood bank of the University of Benin Teaching Hospital, Benin City, Nigeria. Blood group distribution among these samples showed phenotypes A, B, AB and O as 23.72%, 20.09%, 2.97% and 53.22%, respectively. The Rh-D negative phenotype was found among 6.01% of the samples tested.

Iron status of regular voluntary blood donors

Our blood bank is a regional blood transfusion centre, which accepts blood only from voluntary donors.
The aim is to study iron status of regular voluntary donors who donated their blood at least twice in a year.
Materials and Methods:
Prior to blood donation, blood samples of 220 male and 30 female voluntary donors were collected. Control included 100 each male and female healthy individuals in the 18- to 60-year age group, who never donated blood and did not have any chronic infection. In the study and control groups, about 10% subjects consumed non-vegetarian diet. After investigation, 85 males and 56 females having haemoglobin (Hb) levels above 12.5 g/dl were selected as controls. Donors were divided into ≤10, 11-20, 21-50 and >50 blood donation categories. Majority of the donors in >50 donation category donated blood four times in a year, whereas the remaining donors donated two to three times per year. Haematological parameters were measured on fully automatic haematology analyzer, serum iron and total iron-binding capacity (TIBC) by biochemical methods, ferritin using ELISA kits and transferrin using immunoturbidometry kits. Iron/TIBC ratio × 100 gave percentage of transferrin saturation value.
Statistical evaluation was done by mean, standard deviation, pair
and anova (
Preliminary analysis revealed that there was no significant difference in the iron profile of vegetarian and non-vegetarian subjects or controls and the donors donating <20 times. Significant increase or decrease was observed in mean values of various haematological and iron parameters in donors who donated blood for >20 times (
< 0.001), compared to controls. Anaemia, iron deficiency and depletion of iron stores were more prevalent in female donors (
< 0.05) compared to males and especially in those male donors who donated their blood for more than 20 times.
Regular voluntary blood donors should receive iron supplementation to prevent iron deficiency and depletion in iron stores.
Fatal drug-induced immune hemolytic anemia due to cefotetan; A case study
January-June 2008, 2(1):20-23
A case is described here of drug-induced immune hemolytic anemia (DIIHA) due to cefotetan administered to a post-partum woman who received the drug for infection prophylaxis at the time of caesarean section. Renewed fatal hemolysis occurred when the drug was given a second time 12 days after the first dose. The initial immunohematologic findings included a positive direct antiglobulin test (DAT) due to IgG and complement coating of the patient's RBCs as well as an eluate that did not react with RBCs in the absence of drug. The antibody was drug-dependent, reacting with both drug-coated RBCs as well as when the drug was added to a mixture of her serum and donor RBCs. Cefotetan has been a common cause of this uncommon problem. The clinical features of cefotetan DIIHA, classification of drug-induced antibodies, and the differential diagnosis of a positive DAT are briefly discussed.
Emergency therapeutic leukapheresis in a case of acute myeloid leukemia M5
Sudha Ranganathan, Shyamala Sesikeran, Vineet Gupta, Vanajakshi
January-June 2008, 2(1):18-19
Cell separators in India are routinely used for plateletpheresis, peripheral blood stem cell collections and therapeutic plasma exchange. Therapeutic leukapheresis, particularly as an emergency procedure, has been uncommonly performed and reported. Here, a case of a 53-year-old male, diagnosed with acute myeloid leukemia subtype M5 (AML M5) with hyperleukocytosis, who underwent emergency leukaphereis, is reported. After two procedures, there was a decrease of WBC count by 85%, which enabled cytotoxic therapy to be initiated.
The pyramid model as a structured way of quality management
Willem PA van der Tuuk Adriani, Smit Sibinga
January-June 2008, 2(1):6-8
Three quality systems that can be used in blood establishments are briefly explained. The Pyramid model is described as a tool to manage the quality systems. Finally, some experiences in other countries are given to prove the validity of the system.
