    This paper is based on the beta-thalassaemia programme at the Duchess of Kent Hospital, Sandakan, Sabah. It seeks to show that a hypertransfusion regimen which improves the quality of life of children with thalassaemia major can be practised in district and general hospitals if there is an organised blood recruitment programme, at least at departmental level. Such a programme reduces the demand on the hardpressed hospitals' blood banks. Frequent and regular transfusions can be given with minimal interference with the school and family life of affected children and reduces immeasurably the social, emotional and financial strain on the affected families. There is also an urgent need to define the magnitude of the problem of beta-thalassaemia through population studies so that genetic counselling can be given and adequate resources can be allocated to improve the quality of life of affected patients.

    Objectives: Blood bank centers routinely screen for hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) to ensure the safety of blood supply and thus prevent the dissemination of these viruses via blood transfusion. We sought to evaluate the detection of transfusion-transmitted infection (TTI) markers using standard serological methods and nucleic acid testing (NAT) among blood donors in Hospital Universiti Sains Malaysia.

    Methods: Donated blood units were assessed for the presence or absence of HBV, HCV, and HIV using two screening method: serology and NAT. Reactive blood samples were then subjected to serological confirmatory and NAT discriminatory assays.

    Results: A total of 9669 donors were recruited from September 2017 to June 2018. Among these, 36 donors were reactive either for HBV, HCV, or HIV by serological testing and eight by NAT screening. However, only 10 (three for HBV and seven for HCV) donors tested positive using serological testing and five (two for HBV and three for HCV) by NAT discriminatory assays. Note that all five NAT positive donors detected in the NAT discriminatory assays were confirmed to be serologically reactive. Therefore, the prevalence of HBV, HCV, and HIV was 0.03%, 0.1%, and 0.0%, respectively, in our donor pool.

    Conclusions: Both serological and NAT screening and confirmatory assays should be used routinely to reduce the risk of infection transmission via the transfusion of blood and blood components.

    CONTEXT: Whole blood donation is generally considered a safe procedure; however, a small percentage of donors could develop vasovagal reactions (VVRs) during or after completion of blood donation.

    AIMS: This study was undertaken to establish the prevalence of VVR among whole blood donors in Hospital Pulau Pinang and to investigate factors that lead to its occurrence.

    SETTINGS AND DESIGN: A cross-sectional study was conducted involving 27,890 whole blood donations in 2016.

    SUBJECTS AND METHODS: For each donation, donor's demographic and blood donation-related information was extracted from the blood bank database.

    STATISTICAL ANALYSIS USED: Qualitative data including age group, sex, race, frequency, and location of donation were analyzed using Chi-square tests, while blood pressure was analyzed using t-test.

    RESULTS: Overall, 425 cases of VVRs were reported, resulting in a VVR rate of 1.5% (one event in every 65 donations). We found a statistically significant association (P < 0.05) between the occurrence of VVRs with the young age group, female gender, Indian race, first-time donor, lower predonation blood pressure, and donation performed in a mobile donation campaign. The most common vasovagal symptoms are lightheadedness (88%), followed by nausea (5.4%), muscle twitching (3.5%), vomiting (1.4%), loss of consciousness <30 s (1.4%), and paresthesia (0.2%).

    CONCLUSIONS: The prevalence of VVRs among whole blood donors in Hospital Pulau Pinang appeared to be low. Our study reaffirms that blood donation is a relatively safe process, and the incidence of VVR can be further reduced by ensuring strict screening procedure before blood donation.

    Introduction: It is mandatory that every blood donor must have their haemoglobin (Hb) values measured before blood donation. High Hb may indicate an underlying hidden pathological condition. The aim of this study is to investigate the occurrence of the JAK2 V617F gene mutation in blood donors with erythrocytosis. Methods: A cross-sectional study was conducted over a nine-month period involving blood donors with high pre-donation Hb. A total of 45 blood donors with total white cell (TWC) > 12.0x 109/l, platelet > 450x109/ l and Hb > 18g/dL were subjected to JAK2 V617F gene mutation analysis. Samples were collected and analysed for haematological tests and detection of JAK2 V617F mutation. Results: From a total of 2238 blood donors, 175 blood donors had high haemoglobin value. Samples from forty-five of these donors were then analysed for JAK2 V617F using allele-specific polymerase chain reaction (PCR). The prevalence of blood donors with erythrocytosis was 7.8%. All samples were negative for the JAK2 V617F mutation. Conclusions: Erythrocytosis can be relative or absolute and the different causes can be distinguished on the basis of clinical signs and symptoms. An absence of the JAK2 V617F mutation cannot by itself excludes the diagnosis of polycyhaemia vera (PV) since erythrocytosis is the single clinical feature that sets PV apart from other types of myeloproliferative neoplasm (MPN). Further study is required for the detection of other gene mutations that activates the JAK-STAT signalling pathway that could be identified in JAK2 V617F-negative MPN patients.

    Introduction: Unsafe blood products cause transfusion-transmissible infections. A good knowledge and perception about blood safety issues is crucial to ensure safe blood supply. The objective is to develop and validate a question- naire about the knowledge and perception among blood donors on blood safety issues. Method: A cross-sectional study was conducted among 130 blood donors who attended the National Blood Centre, Kuala Lumpur in April and May 2018. The questionnaire was developed in the Malay language after extensive literature search. The self-admin- istrated questionnaire consisted 39 items which required around 20 minutes to complete. The validation involved content validity, construct validity using exploratory factor analysis and reliability using test-retest analysis in IBM SPSS statistics. The same group of respondents was retested after two weeks using the same questionnaire. Results: Content validity was established through multidisciplinary expert meeting and two content reviewers. The factors loadings of all questionnaires were more than 0.40. Knowledge questions were divided into three domains; percep- tion questions were divided into four domains. The intraclass correlation (ICC) values of the test-retest were more than 0.80 for the three knowledge domains and more than 0.60 for the four perception domains. The third domain of the perception section which consisted two questions had the lowest ICC value of 0.686 (95% CI 0.583-0.767). One of the questions was restructured to improve clarity. Conclusions: The questionnaire on knowledge and perception on blood safety issues has good validity and reliability, with appropriate items which warranted its utilization among blood donors.

    Introduction: Reduction or complete absence of α-globin chain production may result α-thalassemia. Alpha thalassemia carrier may have normal haemoglobin level and thus will be eligible as blood donor. Few complications may happen in which the carrier who donated the blood might be at risk of hypoxia and their blood components might not suitable for transfusion. Thus, it is important to screen for α-thalassemia to prevent any complications happen
    after donation. The objective of this study is to investigate the interaction of red blood cell indices and α-globin genotypes among eligible blood donors in a private university, Universiti Tunku Abdul Rahman (UTAR), Malaysia. Methods: A total of 270 eligible blood donors were recruited for this study. Red cell indices were analysed using Horiba hematology analyser and α-globin genotyping was performed for seven alpha deletions, six alpha point mutations
    and two alpha triplications. Results: Our study showed high prevalence of α-thalassemia carriers among the eligible blood donors (7.7%, 21/270), with all of them showed normal Hb level (>12 gm/dl). Five genotypes were detected consisting of 249 αα/αα (92.2%), 9 -α3.7/αα (3.3%), 9 --SEA/αα (3.3%), 2 -α4.2/αα (0.7%) and 1 ααCS/αα (0.4%). All α-globin genotypes showed normal Hb level with no significant difference between genotypes (p=0.167). Different
    α-globin genotypes showed significant difference in RBC, MCV, MCH, MCHC, RDW and Hct/Hb ratio at the p

    Held at Taylor’s University Lakeside Campus, Subang Jaya, Selangor, Malaysia, 8-9th March, 2019
    Introduction: Unsafe blood products cause transfusion-transmissible infections among blood receivers. The knowledge and perception of blood donors is important as it is associated with their donation behaviour and hence the safety of blood products. There was no previous study that assessed the knowledge and perception on blood safety issues among blood donors to date. The objective of this study was to assess the knowledge and perception of blood
    donors on blood safety issues.
    Methods: This was a pilot study conducted to pilot test the self-developed questionnaire by the researchers. The questionnaire was available in the Malay language. One-hundred-thirty donors at the National Blood Centre were recruited to complete the self-administered questionnaire. Health sciences professionals, medical students and non-Malaysians were excluded in this study.
    Results: A total of 130 donors comprising of 70 males (53.8%) and 60 females (46.2%) responded. The mean age of the respondents is 32.48±8.86 years. Most of the respondents were Malay (55.4%), single (49.2%), working in private sector (46.9%) and regular donor (68.5%). More than half of the respondents did not know that dengue, Zika and mad-cow disease can be contracted through blood transfusion. Ten percent of the respondents answered that bisexual people are eligible to donate blood. 40.7% of the donors agreed to check their HIV status through blood donation. Majority of the donors (60.7%) agreed that the donors’ blood is safe if the screening test is negative. Whereas, 33.9% of the donors disagreed that they shall be responsible if their blood causes infection.
    Conclusion: Several knowledge gaps and inappropriate perception among the respondents were identified and these might affect the safety of the blood products. Targeted measures should be taken to rectify donors’ knowledge and perception in order to minimise inappropriate blood donor behaviours and reduce unsafe blood products.

    Introduction: The healthy, active, and receptive huge student population is potential blood donors to meet safe blood requirements. The study aimed to assess the current level of knowledge regarding blood donation of nursing students of the Faculty of Medicine & Health Sciences, UMS and to observe their attitude towards voluntary blood donation and to explore their practice as a voluntary blood donor. Methods: This cross-sectional study was con- ducted from July 2015 to June 2018 among one hundred and eight (108) nursing students who were included in this study by simple random sampling. The researchers explained the study design, objectives, and methodology to the selected subjects and obtained written consent from them. The study assessed the current level of knowledge and observed their attitude towards voluntary blood donation and explored their active involvement in donating blood through a validated questionnaire. Results: There were 89 female and 19 male participants in the study. Almost ev- ery student (96%) knew their blood group and most of them were correct about the health status of a blood donor. They had a lack of knowledge regarding the time required for blood donation and the amount of blood collected in each bag. Although most of the students were very favourable to donate blood, only 34% had previous experience of donating blood out of them; only 6% regularly donated voluntarily and on demand. Conclusion: From this finding, it can be recommended that measures for increasing knowledge regarding blood donation should be taken, and that would result in increased blood donation.

    The two vital aspects of treatment for patients with tha-lassaemia are regular blood transfusions and iron chela-tion therapy. Unfortunately, the use of blood transfu-sions exposes these patients to the risks of acquiring transfusion related viral infections such as hepatitis C. Patients who acquire the hepatitis C virus (HCV) may develop chronic hepatitis and later on hepatocellular carcinoma. Hence, patients with thalassaemia should be regularly screened for the presence of HCV. We report here the results of a cross-sectional study conducted in a typical day-care centre for thalassaemics at the Hospital Universiti Kebangsaan Malaysia, involving 85 multiply transfused patients. We found that 19 patients (22.4%) were seropositive for HCV and two of them had positive HCV-RNA. Those who had started receiv-ing their transfusions before 1995, i.e. the year routine screening for HCV amongst blood donors were com-menced, and those who received transfusions 2-4 week-ly had a significantly higher risk of acquiring HCV infection.

    Thalassaemia screening programme has been conducted in Malaysia since 2004. The aim of the programme was to reduce the burden of the disease by identifying thalassaemia carriers. However, the response towards the screening activities was unsatisfactory as there was lack of public awareness against the importance of thalassaemia screening. An alternative approach is to screen blood donors. The purpose of this study was to observe the prevalence of thalassaemia carriers among healthy blood donors. Seven hundred and thirty eight healthy blood donors were screened in Hospital Tengku Ampuan Rahimah, Klang from July to September 2010 using cation-exchange high performance liquid chromatography (HPLC). Cases with haemoglobin variants were further analyzed by gel electrophoresis at alkaline pH. Result shows that the blood donors consisted of 413 Malays (56%), 162 Indians (22%), 148 Chinese (20%) and 15 others (2%). There were 19 (2.6%) individuals with haemoglobin E trait, six (0.8%) with co-inheritance of haemoglobin E and αα- thalassaemia and five (0.7%) with β-thalassaemia trait. Haemoglobin Constant Spring and haemoglobin A2 prime were observed in two (0.3%); and Haemoglobin Lepore and alpha chain variant in one (0.2%). αα-thalassaemia and normal haemoglobin A2 β-thalassaemia could not be excluded in 190 cases (26%), as they required deoxyribonucleic acid (DNA) studies for identification. Thalassaemia screening in blood donors is more feasible and effective. Therefore, a wider scale population screening including blood donors could benefit the existing thalassaemia screening programme in Malaysia.

    Introduction: It has been suggested that blood donation reduces risks of developing cardiovascular diseases such as heart failure, atherosclerosis, and stroke. Although there are known benefits of blood donation, the inclination of people of the Kurdistan Region of Iraq to donate blood is not known. Therefore, the aim of this study was to determine demograpic and blood biochemical profiles of regular and first-time blood donors in the Sulaimani province of North Iraq.

    Methods: A cross-sectional study was conducted at the Sulaimani Blood Bank, during the period of April 1, 2016 to March 28, 2017, on convenient samples of 100 regular and 100 first-time blood donors. Donor particulars were obtained from blood bank records. The cholesterol, triglyceride, low-density lipoprotein, ferritin, vitamin D3, and uric acid concentrations of blood samples were determined.

    Results: The main reason for blood donation by regular blood donors was headache (45%), while for the first-timers it was to help relatives (31%). The low-density lipoprotein and ferritin concentrations were significantly (p=0.001) lower in the blood of regular donors than first-timers.

    Conclusion: The study shows that regular blood donation is beneficial for the maintenance of health of donors.

    Hepatitis B virus (HBV) infection is one of the major public health problems in Malaysia. It remains the most common permanent deferral among blood donors. In Malaysia, the national vaccination programme has been introduced since 1989 to prevent HBV transmission. The objective of this study is to determine the prevalence and associated risk factors of HBV infection among first-time blood donors after the implementation of the national hepatitis B vaccination programme. Methods: This is a retrospective cohort study involving tracing of the database of National Blood Centre Malaysia. The record of first-time blood donors who had donated between 1st January 2010 and 31st December 2015 and were screened HBV positive was reviewed and analysed. Results: There were 376,737 first-time donors who had donated blood and 575 of them screened positive for HBV. The overall prevalence of seropositive for hepatitis B was 0.15%. The prevalence was higher at 0.23% among donors born before the year 1989 (pre-vaccination era) compared to 0.05% among donors born in and after the year 1989 (post-vaccination era). Perinatal transmission was found to have 15 times higher odds of developing HBV infection as compared to those who had the combination of risk factors among those born after the year 1989 (adjusted OR=14.95, 95% CI 1.80=124.01). Conclusion: The implementation of the national vaccination programme reduced the prevalence of hepatitis B among donors who received vaccination at birth compared to those who did not.

    Dengue virus is one of the emerging agents that can be transmitted via blood transfusion from infected blood donors to recipients. In Malaysia, the increase in dengue infection may contribute to the existence of asymptomatic blood donors and increase the risk of blood supply contaminated with this virus. The aims of this study were to investigate the prevalence of NS1 dengue antigen among blood donors and to ascertain the demographic data of blood donors in Penang and and Perak. Methods: A total of 374 voluntary blood donors were recruited from two blood donation campaigns organised by Hospital Pulau Pinang, Penang and Hospital Raja Permaisuri Bainun, Ipoh, Perak from April to May 2016. From each centre, 187 voluntary blood donors were enrolled, blood was collected and Dengue NS1 Ag was screened on all the samples using Platelia dengue antigen test kit from Bio-Rad Laboratories, France. Results: All 374 samples were found to be negative for the Dengue NS1 antigen. Demographic data of these blood donors showed that the most common blood group was O Rh positive, men donated more than women and Chinese blood donors were the biggest group of donors. Conclusion: Even though dengue is endemic in Malaysia, none of the blood donors was screened positive for dengue NS1 antigen in the areas studied. This indicates that none of the blood donor at the time of donation was in viraemia stage. The established donor screening program ensures that the dengue transmission through transfusion is minimal in the areas studied.

    Kidd blood group system is distributed differently within populations. In Malaysia, the prevalence of Kidd phenotypes have been reported but not in Hospital Umum Sarawak (HUS).We characterised Kidd phenotypes among regular blood donors in HUS. Methods: A cross-sectional study was done from 1st September 2015 to 10th September 2015. Blood samples were collected from 250 regular blood donors of different ethnicities in HUS. Samples were then investigated for Kidd blood group phenotypes by utilising Seraclon anti-Jka and anti-Jkb reagents employing the Diamed-ID gel card system. Results: Phenotype Jk(a+b+) was found in 110 out of 250 (44.0%) and phenotype Jk (a-b-) phenotype in seven out of 250 (2.8%) blood donors. Jk(a+b-) was detected in 60 out of 250 (24.0%) and Jk(a-b+) in 73 out of 250 (29.2%) donors. Kidd phenotype was detected in four ethnics; Chinese 50.8%, Malays 38.4%, Bidayuh 10.0% and Iban 0.8%. Jk(a-b-) phenotype was present only in the Malays; seven out of 250 (2.8%) but not found in other ethnicities. Conclusion: Jk(a+b+) is the most common Kidd phenotype found in regular blood donors in HUS in the four ethnicities studied. Only Malays exhibit the Jk(a-b-) phenotype which is a rare phenotype. The results of this study may serve as a preliminary database for Kidd blood group profile of regular blood donors in HUS.

    Background: Unsafe blood products may cause transfusion-transmissible infections. This study aimed to evaluate the knowledge and perceptions of blood donors regarding blood safety.

    Methods: This was a cross-sectional study conducted in the Kelantan state of Malaysia. The questionnaire comprised 39 questions that covered areas such as donors' social demographic information, knowledge of transfusion-transmitted diseases, blood screening and donor eligibility and perceptions towards blood safety. The knowledge score was categorised as good or poor.

    Results: Of the 450 distributed questionnaires, 389 were suitable for analysis. Only 18.5% of the donors had good knowledge, with 81.5% having poor knowledge. Less than 30% were aware that people with multiple sexual partners, bisexual people and male homosexual people are permanently deferred from blood donation. Only 29.4% agreed that donors are responsible if their blood causes infection. Furthermore, 39.3% assumed that they could check their HIV status through blood donation, and 10.3% and 5.4% of the respondents believed that donors are free from infection if they wear a condom during sex or only have oral sex when involved in prostitution, respectively.

    Conclusion: Poor knowledge and notable misperceptions concerning safe blood donation were found among blood donors. The Ministry of Health should incorporate safe blood education in future public awareness programmes.

    Helicobacter pylori infection is recognized as being strongly associated with chronic gastritis, duodenal ulceration and, probably, gastric carcinoma. Seroepidemiological studies have shown that a large proportion of healthy people have antibodies against H. pylori. A serological study was conducted in asymptomatic healthy blood donors in Northern Peninsular Malaysia to assess the seropositivity for H. pylori and to investigate the relationship with ethnic group, gender, ABO blood group and age. A total of 5370 serum samples collected from 3677 male and 1693 female donors in different age groups, and who had no gastrointestinal complaints, were studied with an in-house ELISA for the presence of H. pylori IgG and IgA antibodies. Seven hundred and sixty subjects (14.2%) were seropositive. The overall seropositivity did not differ with ethnicity, gender, ABO blood group and age among asymptomatic healthy blood donors in Northern Peninsular Malaysia.

    Iron deficiency is the commonest cause of anemia worldwide and healthy blood donors are estimated to lose about 236 mg of iron with each donation. The objective of this study was to determine the serum ferritin levels among first time and regular male blood donors, and also to correlate the serum ferritin levels with the number of donations and hemoglobin levels. Hemoglobin levels and serum ferritin were measured in three groups of donors divided into first time donors; (n = 92), donors with 2-4 donations (n = 41), and regular donors (n = 78). The mean hemoglobins in the first time donors, second group and regular blood donor group were 14.95 +/- 1.08, 15.12 +/- 1.44 and 15.56 +/- 1.48, respectively. The serum ferritin level were found to be significantly lower among the regular donors (62.0 +/- 39.78 ng/ml) compared to first time donors (90.7 +/- 66.63) and second group donors (114.12 +/- 66.97). The serum ferritin levels gradually decrease according to the number of donations and there was a significant correlation between frequency of donations and the serum ferritin level (r2 = 0.082). Significant correlation between the number of donations and hemoglobin level r2 = 0.061) was noted. However, there was no significant correlation between hemoglobin and serum ferritin levels (r2 = 0.015). Eleven percent of regular donors had depleted iron stores. This was not noted in donors who donated less than 5 times within 2 years.

    Pre-donation screening declarations and hemoglobin (Hb) testing are measures used to determine the quality of donated blood. The copper sulphate (CuSo4) method used to screen for blood abnormalities can give inaccurate results if strict quality control is not applied. Blood donors who are carriers of thalassemia and those with mild iron deficiency anemia (IDA) are usually asymptomatic and frequently missed at blood donation. The aim of this study was to evaluate the red blood cell (RBC) indices related disorders among blood donors who were deemed qualified to donate blood after screening with CuSo4 method. One hundred fifty-eight volunteer blood donors at the Universiti Putra Malaysia (UPM), who had passed the CuSo4 screening method, were recruited for this study. Their bloods specimens were examined with a complete blood count. Subjects with a low mean corpuscular hemoglobin (MCH) level were examined further by checking a serum ferritin level, Hb quantification, and molecular analysis to examine for common RBC disorders. Fourteen point six percent of subjects had a low Hb level, two (1.3%) had IDA and four (2.5%) had thalassemia or some other hemoglobinopathy. Using a MCH level < 27 pg as a cut-off point, 58 subjects (36.7%) had suspected IDA, thalassemia or some other hemoglobinopathy. Eight point nine percent of subjects with a normal Hb level had thalassemia, and 3.8% had IDA. Malaysia has a high prevalence of thalassemia and other hemoglobinopathies. Pre-donation accurate screening is crucial to protect the quality of blood transfusion products. Public education regarding RBC disorders especially among blood donors is important.
