Malaria is a protozoan parasitic infection of humans resulting from one or more of the five species of the genus Plasmodium and its burden across the world particularly in the tropics is well known. Blood transfusion on the other hand is a necessary intervention in saving lives. However, it can lead to transfusion transmitted infections including malaria if the blood was donated by an infected person. It is therefore important that the blood from donors in malaria prone environment be examined thoroughly for malaria parasites. The objective of this study was to investigate the incidence of malaria parasites in donor blood. A total of 1,500 samples from donors were examined using microscopy, rapid diagnostic test (RDT), and molecular method for malaria parasites. Malaria parasites were detected in forty-eight (48), 49 and 47 of the blood samples using microscopy, RDT, and molecular method respectively. This gave an average prevalence of 3.2%. All the blood groups examined had some malaria positivity except blood group O and A negative. In all the positive samples, the trophozoites of Plasmodium falciparum were detected. There was no association between blood group type and prevalence of the malaria parasites. There was also no association between age and prevalence of malaria parasite. The results attest to the potential risk of blood transfusion transmitted malaria and thus pose a great risk to blood recipients, especially the malaria vulnerable groups of children and pregnant women. Even though the prevalence in this study was not high enough, together with other results from elsewhere, it can be said that the screening of donated blood or donors for malaria parasites is necessary so that measures will be put in place not to transfuse patients at risk.

Introduction. Screening and identification of anti-erythrocyte alloimmune antibodies in recipients is an important and necessary step in their testing before blood transfusion.Aim. To formulate algorithms that could facilitate the process of pre-transfusion immunohematological testing.General findings. Such a testing allows the development of post-transfusion reactions and complications to be avoided. The presence of alloantibodies of various specificities and autoantibodies in the test blood may complicate pre-transfusion testing and require the use of additional methods (adsorption, elution, etc.). The author has proposed an effective system of algorithms for conducting immunohematological studies, which can be used to identify patients at risk of developing immune post-transfusion complications and ensure an individual selection of compatible donor blood-transfusion products.

Background: Blood transfusion saves life of patients with severe anaemia. However, blood transfusion can transmit blood-borne parasites. Despite malaria being endemic in Tanzania, there is limited information on asymptomatic malaria among blood donors. This study determined the prevalence and associated factors of asymptomatic malaria among blood donors at the Lake Zone Victoria Blood Transfusion Centre in Mwanza, Tanzania.Methods: A cross-sectional study was conducted between March and April 2016 among blood donors without any symptoms of malaria. During blood donation, samples were collected from each participant. Malaria parasites were detected microscopically from Giemsa stained thin and thick smears and by the use of malaria rapid diagnostic test (MRDT).Results: A total of 150 blood donors participated in this study. The median age of participants was 20 (IQR: 18-27) years. Malaria prevalence by microscopy was 5.3% (95% CI: 1.7-8.8) while by MRDT was 8% (95% CI: 3.6-12.3). Malaria mean parasite density was 12mps/200WBC. Only individuals who reported using mosquito nets were found to be protected from getting asymptomatic malaria on multivariate logistic regression analysis (OR: 0.04, 95% CI: 0.01-0.25, P<0.001).Conclusion: A considerable proportion of blood donors in Mwanza, Tanzania are infected with P. falciparum which poses a risk for transmission to blood recipients including malaria vulnerable groups like pregnancy woman and children. Screening donated blood for malaria parasites is recommended in malaria endemic areas to prevent possible fatal consequences.

Background. Asymptomatic malaria parasitaemia has been documented in donor blood in West Africa. However, donated blood is not routinely screened for malaria parasites (MPs). The present study therefore aimed to document the frequency of blood transfusion-induced donor-recipient malaria parasitaemia patterns, in children receiving blood transfusion in a tertiary health-centre. Methodology. A cross-sectional, observational study involving 140 children receiving blood transfusion was carried out. Blood donor units and patients’ blood samples were obtained, for the determination of malaria parasites (MPs). Giemsa staining technique was used to determine the presence of malaria parasitaemia. Results. Malaria parasites were detected in 7% of donor blood and in 8.3% of the recipients’ pretransfusion blood. The incidence of posttransfusion MPs was 3%, but none of these were consistent with blood transfusion-induced malaria, as no child with posttransfusion parasitaemia was transfused with parasitized donor blood. Majority of the blood transfusions (89.4%) had no MPs in either donors or recipients, while 6.8% had MPs in both donors and recipients, with the remaining 3.8% showing MPs in recipients alone. Conclusion. In conclusion, the incidence of posttransfusion malaria parasitaemia appears low under the prevailing circumstances.

Abstract Background Previous studies have reported the efficacy and safety of intravenous (IV) iron therapy during the perioperative period as an alternative and adjunct to allogeneic blood transfusion. Preemptive IV iron therapy provides noninferior hemoglobin levels on postoperative day (POD) 1 compared to autologous whole blood therapy (AWBT) in healthy patients who had undergone bimaxillary orthognathic surgery. Methods This was a prospective, patient-randomized, noninferiority trial. After excluding 2 patients, 64 patients were divided into two groups: the IV iron therapy group (patients received IV iron infusion 4 weeks before surgery; n = 32) and the AWBT group (2 units of autologous whole blood were collected 4 and 2 weeks before surgery; n = 32). The primary outcome was hemoglobin level on POD 1 and the prespecified noninferiority limit was − 1 g/dL. Results Baseline data were comparable, including hemoglobin and iron levels, between the two groups. Immediately before surgery, the levels of hemoglobin, iron, and ferritin were higher in the IV iron group than in the AWBT group. The mean treatment difference (iron group—whole blood group) in hemoglobin level on POD 1 between the two groups was 0.09 (95% CI = − 0.83 to 1.0). As the lower limit of the 95% CI (− 0.83) was higher than the prespecified noninferiority margin (δ = − 1), noninferiority was established. On POD 2, the hemoglobin level became lower in the iron group, which eventually led to greater requirement of allogeneic blood transfusion compared to the whole blood group. However, the iron group did not require allogeneic blood transfusion during or early after surgery, and the whole blood group showed continuously higher incidence of overt iron deficiency compared to the iron group. Conclusion As collection of autologous whole blood caused overt iron loss and anemia before surgery and intraoperative transfusion of whole blood was not able to prevent the occurrence of persistent iron deficiency after surgery, IV iron therapy was found to have potential benefits for iron homeostasis and subsequent erythropoiesis in healthy patients early after bimaxillary orthognathic surgery.

Background: Blood transfusion unit collection, storage and dispatching on Birat Medical College and Teaching Hospital began from 19 June 2016 via blood bank. After which, many blood distribution were made accessible via this service. This study analyzes the blood transfusion request and utilization pattern and also to monitor for managing the bloodstocks meeting present and future demand in hospital. Materials and Methods: This is descriptive cross-sectional study conducted for all the requests of whole blood dispatched from 19th June, 2016 to 04th July, 2018. Whole blood requisitions from various departments were reviewed regarding the number of requisition, total blood unit replaced, blood group and socio-demographic profile of patients.Results: Of 648 transfusion units dispatched, 131 and 324 patients were male and female respectively, B positive blood group were most common, followed by A positive, O positive, AB positive, A negative, O negative and AB negative respectively. The largest numbers of requisitions were from Gynecology and Obstetric department in the hospital of 258 requisitions followed by internal medicine, surgery department, postoperative ward and orthopaedic department. Majority of the requisitions were for 20-29 years age group from the local district Morang. The total blood units replaced were 75, of which 29 and 46 of male and female respectively. Conclusions: B Positive was the predominant requested blood group with Gynecology and Obstetrics department making the most requests, among 20-29 years age group from Morang district. The total replaced blood units were less in number with some requisition forms even lacked essential details.

The purpose of this study was to identify the best method of autologous blood transfusion to be applied in an East African hospital. One hundred and nine consecutive patients for whom major blood loss was anticipated were enrolled. Seventeen patients donated 1 unit of blood 3 days preoperatively and 92 underwent acute isovolaemic haemodilution prior to induction of anaesthesia. For the haemodiluted patients a 2:1 ratio of sterile pryogen-free saline to collected blood was used. One of the 16 patients from whom 2 units were withdrawn by haemodilution experienced hypovolaemia which was rapidly restored by additional transfusion of colloid. Of the patients who donated blood preoperatively only 23.5% were autotransfused compared to 98.9% of the haemodiluted patients. Of the latter 23.9% (22) had an intraoperative blood loss exceeding 15% of their total blood volume and 7.6% (7) lost more than 25%. Only one received homologous blood in addition. For hospitals with limited blood bank facilities and regular cancellation of surgery, the use of acute isovolaemic haemodilution is recommended. A 3:1 ratio of saline to blood is now advised when 1 unit is withdrawn and a part replacement with crystalloid when 2 units are collected.
