Samad NA, Yong PW, Mahendran K

Malays J Pathol, 2015 Aug;37(2):137-40.
PMID: 26277670 MyJurnal

BACKGROUND: Data from the National Health and Morbidity Survey 2011 showed that 20.8% of Malaysians above 30 years have diabetes. 10.1%of them are undiagnosed. Mobile blood drives could complement the public health department efforts in diabetes screening for early detection of the illness.
AIMS: This study aims to determine the necessity of diabetes screening as a routine screening program during blood donation campaign.
METHODS AND MATERIAL: Blood donation campaigns which involved the public community between January 2013 and June 2013 were included in this study. Donors above 30-years-old, not known to have diabetes, consented for diabetes screening. Diabetes screening was done by checking random capillary blood sugar (RCBS) levels while performing a Hemoglobin test and ABO grouping. Donors with RCBS of ≥ 7.8 mmol/L were given appointments for oral glucose tolerance test (OGTT) to confirm the diagnosis of diabetes.
RESULTS: A total of 211 diabetes screenings were performed. Mean RCBS was 6 mmol/L. 43(20.4%) donors had RCBS≥ 7.8 mmol/L. 10 donors were later diagnosed to have diabetes (5.0%) and 5 donors were prediabetes (2.5%). 9 donors (4.3%) did not turn up for further investigation.
CONCLUSIONS: Blood donors are expected to be healthy volunteers. The diabetes prevalence among blood donors (5.0%) is considered low if compared with the prevalence in the whole population (20.8%). However, the number is largely comparable to the prevalence of undiagnosed diabetes in the country (10.1%). Routine diabetes screening during blood donation campaign should be implemented to safeguard donors' health and serve as a public health initiative to improve community health.

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.

PMID: 23077846

The aim of this study was to determine the prevalence of HCV infection and the signal/cutoff (S/CO) value for false reactive, false positive, indeterminate and true positive HCV infection among apparently healthy blood donors in our area. This retrospective study was conducted at the Transfusion Medicine Unit, Hospital Universiti Sains Malaysia from June 2008 to June 2009. Blood samples were screened for anti-HCV using enzyme immunoassay (EIA). Reactive cases were confirmed by recombinant immunoblot assay (RIBA). Sixty-one blood donors were found to be reactive after the first screening test. Twenty-nine blood donors had reactive repeat screening, with only 9 samples being true positives. The S/ CO for false reactive, false positive, indeterminate and true positive anti-HCV samples were 1.02 to 1.45, 1.01 to 2.09, 1.07 to 2.43 and 35.95 to 119.89, respectively. The analysis showed the low incidence of HCV infections among blood donors in our area, however, thorough donor screening and stringent selection criteria are still recommended to eliminate high risk donors to improve our blood transfusion service.

Introduction:Transfusion Transmitted Infections is occurring worldwide. The common organisms related reported in literature were Human Immunodefiency Virus, Hepatitis B and C Virus, bacterial contamination and Malaria par-asites. Meanwhile, Melioidosis is endemic disease in Malaysia and especially Sabah. Mortality due to Melioidosis septicaemia was also high. It ranges between 60%-80%. In Sabah, 74% of Thalassemia children were diagnosed with Bacteraemia Melioidosis and 50% had died due to the organisms. The incidence of Melioidosis Transfusion Transmitted Infection is rarely reported in the literature. Case Description: A 17-year-old girl was diagnosed having Beta thalassemia major since 5 years old and splenectomised 8 years ago. Currently on prophylaxis Penicillin and Ex-jade. She was admitted into hospital for monthly blood transfusion. Two days prior to admission, patient complained of having sore throat and cough but no fever and other complained. On examination, the tonsil enlarged and was treated as exudative tonsillitis. She was transfused with 2 pint packed cells within 2 days. No transfusion reaction noted. Day seven admission, she had high grade fever and redness of the right hand cannulation site and was treated as right hand cellulitis with intravenous Cloxacillin. Full blood count shows Total White Cell count was 24.9 x109 /L, Haemoglobin level was 9.3 g/dl and Platelets was 462x109/L. Blood for culture and sensitivity was taken and Chest X-ray noted haziness over the left mid and lower zone of the lung and was treated as Hospital Acquired Pneumonia. She was referred to tertiary hospital for further management. Her conditioned deteriorated and died at the casualty unit in the tertiary hospital. Blood culture was positive for Burkholderia pseudomallei. The case was reported to Dis-trict health office for further investigation. Blood donor tracing was done and was positive for Melioidosis through Elisa Antibody titre IgM for Melioidosis (1:320). The patient’s house and school were visited and investigated. All environmental samples were negative for Burkholderia pseudomallei. Conclusion: Its shows a relationship between blood donations infected with Burkholderia pseudomallei causing mortality of Beta Thalassemia patients. It is highly recommended to screen all blood products for communicable disease fatal organisms.

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.

Fulltext The management of beta-thalassemia in an urban district hospital

Lyn PCW, Teh HC, Mulvey RF

Med J Malaysia, 1985 Mar;40(1):3-10.
PMID: 3831730

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.

Mohamed S, Muna I

Med J Malaysia, 2013 Oct;68(5):393-6.
PMID: 24632868

OBJECTIVE: We here report the first study on the distribution of red cell antigens and phenotype frequencies of various blood group systems in Maldives.

METHOD: Randomly selected 123 regular blood donors of O group were phenotyped for seven blood group systems by direct tube agglutination and or indirect antiglobulin tests. Blood group systems studied were Rh, Kidd, Duffy, Lewis, Kell, P and MNS system.

RESULTS: Rh blood grouping showed, 7.3% donors were Rh(D) negative, 92.7% were Rh(D) positive with the predominance of genotype complex of DCe/DCe (39.0%). The incidence of Jk(a+b+) phenotype was the most common in Kidd system. In Duffy system, the incidence of Fy(a+b+) phenotype was 50.4%. Lewis system was predominated by Le(a-b+) phenotype accounting to 80.5% of the donors. In the Kell system only two phenotypes were present, K+k- (5.7%) and k+k+ (94.3%), in the Maldivian blood donors. P system was represented by P1, P2 and P2k phenotypes with an incidence of 28.5%, 70.7% and 0.8% respectively. In the MNS system, MNss and MNSs phenotypes summed up to 48.8% of blood donors.

CONCLUSION: The detail knowledge of red cell antigen composition and their frequencies in the Maldivian population will be helpful in terms of population genetic perspectives, in establishing a donor data-bank for in-house production of indigenous screening and identification cell panels, and facilitate availability of antigen negative compatible blood for patients with previously identified multiple alloantibodies.

Hossain Parash M, Suki NM, Shimmi SC, Hossain ABMT, Murthy KD

Transfus Clin Biol, 2020 Apr;27(2):70-77.
PMID: 32139133 DOI: 10.1016/j.tracli.2020.02.002

OBJECTIVE: This study aims to examine the behavioural intention of students to make voluntary blood donations. Moreover, it uses a theory of planned behaviour as its guiding principle and does so within the context of Malaysia, a developing nation.
METHODS: Data were collected via a self-administered questionnaire from a sample of 500 students at a public higher learning institution in Malaysia. Structural equation modelling approach (SEM) was performed to assess the strength of the hypothesized relationships of the proposed model simultaneously via the two-stage model-building process.
RESULTS: The SEM approach revealed that knowledge was the most influential predictor of students' intention to make a voluntary blood donation. With the knowledge that the more blood they donate, the more lives will be saved, the inclination to donate blood is intensifying among students. Moreover, all of the TPB constructs applied were also seen to significantly influence students' response to voluntary blood donation.
CONCLUSIONS: The nexus of attitude, subjective norm, perceived behavioural control, and knowledge about students' intention to perform voluntary blood donation are evidenced in a developing nation. The implications of the study and directions for future research are provided.

Fulltext Genetic polymorphisms of human platelet antigens-1 to -6, and -15 in the Malaysian population

Tan JY, Lian LH, Nadarajan VS

Blood Transfus, 2012 Jul;10(3):368-76.
PMID: 22682339 DOI: 10.2450/2012.0095-11

Human platelet antigens (HPA) are determinant in several platelet-specific alloimmune disorders, such as neonatal alloimmune thrombocytopenia, post-transfusion purpura and platelet transfusion refractoriness. The distribution of HPA systems in the Malaysian population is not known. Defining the patterns of HPA systems provides a basis for risk assessment and management of the above complications.

Fulltext Immune haemolysis after renal transplantation secondary to ABO minor-mismatch between donor and recipient

Jayaranee S, Ramesh P, Nadesan V

Singapore Med J, 2002 Aug;43(8):421-2.
PMID: 12507029

Immune haemolysis following renal transplantation has been reported and known causes include infection, medication and metabolic disturbances (1,2). Autoimmune haemolysis after renal transplantation secondary to ABO minor mismatch is an uncommon but important cause that should be considered in the differential diagnosis of post-transplantation haemolysis. A case of haemolytic anaemia caused by graft versus host antibody formation is presented. We suggest that direct Coomb's test should be done as a routine in all cases of ABO mismatch renal transplantation and red cells compatible with both donor and recipient or group "O" packed cells should be transfused if transfusion is indicated.

Fulltext The prevalence of anti-HCV antibody in risk groups and blood donors

Ng KP, Saw TL, Wong NW, Goh KL, Chuah SY, Nagaratnam M

Med J Malaysia, 1995 Dec;50(4):302-5.
PMID: 8668047

Anti-HCV antibody was detected in 1.9% of the blood donors in University Hospital. Among the risk groups, 33.3% of the patients with post-transfusion hepatitis were tested positive for anti-HCV antibody. The anti-HCV antibody was detected in 30% of the IDU. Haemodialysis patients, patients with acute and chronic hepatitis and patients with liver cirrhosis appeared to have increased risk of Hepatitis C virus infection. The results indicate that the frequency of HCV infection increases with the exposure to blood or blood products.

Why is acute leukemia more common in males? A possible sex-determined risk linked to the ABO blood group genes

Jackson N, Menon BS, Zarina W, Zawawi N, Naing NN

Ann Hematol, 1999 May;78(5):233-6.
PMID: 10391104

Acute leukemia is more common in males at almost every age, and this fact remains unexplained. A study was carried out in northeast peninsular Malaysia, where the population is predominantly Malay, to examine whether there was a difference in ABO blood group distribution between males and females with acute leukemia (AL). The ABO blood groups of 109 male and 79 female patients with AL (98 ALL, 90 AML) were compared with those of 1019 controls. In the control population, 39.7% were group O. Among males with AL, 39.4% were group O, whereas among females with AL, the proportion was 24.1% (p=0.03). The same trend to a lower proportion of group O among females was seen if the group was divided into adult/pediatric or lymphoblastic/myeloblastic groups, though these differences were not statistically significant. If these findings can be confirmed, they suggest the presence of a "sex-responsive" gene near to the ABO gene locus on chromosome 9, which relatively protects group O women against AL, at least in our population. The existence of such a gene might also partly explain why acute leukemia, and possibly other childhood cancers, are more common in males.

The World Health Organization (WHO) recommend that all donated blood are to be screened for at least three viral infections [human immunodeficiency virus (HIV), hepatitis C virus (HCV), hepatitis B virus (HBV)]. The National Blood Centre, Kuala Lumpur (NBCKL) aims to reduce transfusion transmitted infections (TTI) as it still remains as one of the major risk for blood transfusion. A cross sectional study was conducted at the National Blood Centre, Kuala Lumpur from 1st January 2009 to 31st June 2010. Data from 581,020 donors were analyzed from year 2004 to 2008. All data were retrieved from NBCKL Blood Bank Information System (BBIS). A total of 201 repeat donors were included in the study based on the inclusion criteria but only 132 repeat donors agreed to participate. Information on sociodemographic, risk factors, knowledge of donors and high risk behavior were extracted from standardize questionnaire. Data were analyzed using SPSS version 14.0. The aim of this study was to determine the predictors of the seropositive infectivity among repeat blood donors at the NBCKL. The results showed Syphilis accounts for the highest and increasing seroconversion rate among other infections from 20.83 % in year 2004 to 44.6 % in year in year 2008. HIV and HCV infection also showed increasing seroconversion rate in 5 years' time from 6.41 % in year 2004 to 17.54 % in year 2008 and 4.8 % in year 2004 to 5.94 % in year 2008 respectively. However, HBV infection alone showed a decreasing seroconversion rate from 20.83 % in year 2004 to 10.4 % in year 2008. Level of donors' awareness regarding high risk factors (activities or behaviour) can lead to higher risk of TTI with significant p value in this predictors model(p blood donors with high risk activities are more likely to have seropositive results for HBV, HIV and Syphilis. This study found that the frequency of HCV seropositivity is higher among lapsed donor. Socio demographic factors such as male and working in the private sector predominates in all TTI markers. Majority of the respondents were aware about relation of high risk activities and risk of TTI.

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.

Malays J Med Sci, 2019 Jan;26(1):58-65.
PMID: 30914893 MyJurnal DOI: 10.21315/mjms2019.26.1.5

Background: The Kidd (JK) blood group system is of clinical importance in transfusion medicine. JK*A and JK*B allele detections are useful in genetic anthropological studies. This study aimed to determine the frequencies of JK*A and JK*B alleles among Muslim blood donors from Southern Thailand and to compare how they differ from those of other populations that have been recently studied.
Methods: A cross-sectional study was used. Totally, 427 samples of dissimilar Thai-Muslim healthy blood donors living in three southern border provinces were selected via simple random sampling (aged 17-65 years old) and donors found to be positive for infectious markers were excluded. All samples were analysed for JK*A and JK*B alleles using PCR-SSP. The Pearson's chi-squared and Fisher exact tests were used to compare the JK frequencies among southern Thai-Muslim with those among other populations previously reported.
Results: A total of 427 donors-315 males and 112 females, with a median age of 29 years (interquartile range: 18 years)-were analysed. A JK*A/JK*B genotype was the most common, and the JK*A and JK*B allele frequencies among the southern Thai-Muslims were 55.2% and 44.8%, respectively. Their frequencies significantly differed from those of the central Thai, Korean, Japanese, Brazilian-Japanese, Chinese, Filipino, Africans and American Natives populations (P < 0.05). Predicted JK phenotypes were compared with different groups of Malaysians. The Jk(a+b+) phenotype frequency among southern Thai-Muslims was significantly higher than that of Malaysian Malays and Indians (P < 0.05).
Conclusions: The JK*A and JK*B allele frequencies in a southern Thai-Muslim population were determined, which can be applied not only to solve problems in transfusion medicine but also to provide tools for genetic anthropology and population studies.

Many factors contribute to the reluctance towards blood donation, but available studies done in Malaysia involving University students does not reflect the knowledge of the public in general. The objective of this study is to determine knowledge, attitude practice towards blood donation among the Sandakan population. A cross-sectional study was employed using an adapted 29-item structured validated questionnaire available in English and Bahasa, consisting of subject’s demography, questions regarding knowledge, attitude, and perception of blood donation. Convenient random sampling was done within the hospital compound, 79 healthy adults consented, and their data were used for the final data analysis, yielding an excellent internal consistency (Cronbach’s α coefficient = 0.816). Out of all, 74.7% of the respondents had a high level of knowledge, and independent t-tests showed that those who were not married, had tertiary education, donated blood in the past, had a statistically significant higher level of knowledge and 96.2% of respondents have a positive attitude. Some donors (40.6%) donated blood for moral satisfaction, and only a quarter (25%) experienced adverse events. Fear of pain, needle, fainting was the highest reason for reluctance in blood donation (36.2% of non-donors), followed by self-perception of being medically unfit to donate (31.9% of non-donors). Even though the sampled population in Sandakan showed an adequate level of knowledge as well as a positive attitude towards blood donation, blood product shortage is still present. This study may contribute by serving as an educational platform for awareness and education to improve the number of blood donors.

Al-Kubaisy, Waqar A., Niazi, Amjad D.

Int J Public Health Res, 2011;1(2):72-78.
MyJurnal

Introduction Hepatitis C Virus (HCV) recently was identified as a major cause of post transfusion hepatitis world wide. To evaluate the role of blood transfusion on the prevalence of HCV infection, by testing antibody and RNA as well as the genotypes of HCV .Also to detect if Blood transfusion acts as unconfounding risk factor for HCV infection.
Methods Sera from 3491 pregnant women were investigated for the presence of HCV antibodies (anti-HCV) by using third generation enzyme immunoassay (EIA-3) as screening test, followed by immunoblot assay (Lia Tek-III). In addition 94 sera of studied women were subjected to molecular analysis (at laboratories of Sorin BioMedica - Italy) for the detection of viral RNA and genotypes of HCV. Using RT-PCR & DNA Enzyme immunoassay (DEIA) method.
Results Our study revealed, that seroprevalence rate of HCV specific Ab & RNA were significantly higher (16.32 %, 80% respectively) among women with a history of blood transfusion, compared to those (2.53%, 56.5%) with no such history P=0.0001, P=0.01. And there is a significant direct linear correlation between number of blood transfused and the seropositive rate of anti-HCV (r=0.7, p=0.046). Based on multivariate analysis, interestingly, this study confirmed that, blood transfusion significantly acting as unconfounding risk factor for acquiring HCV infection (Adjusted OR=1.938,95% C.I=1.646-2.28). And the risk of exposure is increases with increased number of blood transfused. Although, we found no significant association between, HCV genotypic distribution and history of blood transfusion. However, high proportion of women with a history of blood transfusion were harboring HCV genotype -4 or 1b, 50%,40%, resepctively.
Conclusions Our study shows, evidence that, blood transfusion acts as unconfounding risk factor for acquiring and in a mode of transmission of HCV infection. Therefore strict screening of blood donor for HCV-Abs and / or RNA is highly recommended.

PMID: 26863862

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.
