INTRODUCTION: Blue Rubber Bleb Nevus Syndrome (BRBNS) also known as Bean's Syndrome is an atypical type of vascular malformation. To date, around 200 cases have been reported world-wide. In view of its low incidence rate, clinicians might misdiagnose and under treat. The key features of this syndrome are characterized by multiple cutaneous, soft tissue and gastrointestinal tract venous malformations.
PRESENTATION OF CASE: We report the first case of Blue Rubber Bleb Nevus Syndrome in Malaysia, a 23 years old Malay girl who suffers from multiple cutaneous venous malformation and gastrointestinal bleeding episodes.
DISCUSSION: The typical morbidity for this syndrome is symptomatic anemia due to secondary iron deficiency due to the gastrointestinal venous malformation bleeding. In managing the gastrointestinal bleeding, it mainly depends on the severity of gastrointestinal bleeding, some may resolve spontaneously, while the others may be needing blood transfusion, and some may require GIT resections. As for cutaneous lesions, normally it is innocuous depending on the region and size. Large or problematic cutaneous venous malformation might benefit from sclerotherapy or excision.
CONCLUSION: Multidisciplinary approach is crucial in managing BRBNS case due to its complexity and the spectrum of multiple organ involvement to ensure the best outcome to the patient.

Fulminant haemorrhage in cervical cancer leads to severe anaemia and haemodynamic instability. Palliative management includes vaginal packing as temporary measure, radiotherapy and other invasive surgical procedures. High dose emergency chemotherapy is not commonly implemented particularly when complicated with anaemia and renal impairment. We discuss three case series on the usefulness of high dose chemotherapy to combat bleeding from cervical cancer as an emergency treatment. The first case was clinically staged as operable 2A disease with severe anaemia due to bleeding from the tumour mass. The haemoglobin was corrected by blood transfusion while the bleeding was being arrested by high dose chemotherapy. The second case was inoperable with invasion to the bladder mucosa. She had frank haematuria and bleeding from the tumour with severe anaemia. A course of chemotherapy and blood transfusion controlled the bleeding and anaemia was corrected. The third case presented late with obstructive uropathy and anaemia. She required dialysis, blood transfusion and high dose emergency chemotherapy to stop the bleeding before undergoing urinary diversion after an unsuccessful ureteric stenting. High dose chemotherapy consisting cisplatin, vincristine, bleomycin and mitomycin-C has a clinical value in arresting fulminant haemorrhage in cervical cancer.

Thalassemia and the blood transfusion complications associated with it predispose children to poor bone health. This study was conducted to determine the prevalence of bone-related abnormalities and identify the bone health predictors within this population. One hundred and forty transfusion-dependent beta thalassemic subjects 8-18 years old in Mashhad, Iran, participated in this cross-sectional study. Anthropometric measures, dietary intake, bone-related biomarkers and bone densitometry, were assessed. The incidence of underweight and short stature was 33.6 and 41.4 %, respectively, which were indicators of malnutrition among thalassemic subjects in this study. Low bone density was detected in the lumbar spine and femoral region in 82 and 52 % of subjects, respectively. Hypocalcemia and hypophosphatemia were seen in 22 and 18.2 %, whilst vitamin D deficiency was present in more than 85 % of thalassemic children and adolescents. The relationships between weight, height and other anthropometric indices, serum calcium and bone markers, intake of macronutrients, zinc and vitamin E with bone mineral density (BMD) and bone mineral content (BMC) in the lumbar spine and femoral area were positively related, indicating that better nutritional status were associated with higher BMD and BMC values. Puberty, gender and serum osteocalcin were negative predictors for BMD and BMC values, whereas age, weight and height were the positive predictors. High incidence of low bone density and deficit in other aspects of bone health among thalassemia patients makes routine bone health assessment necessary for this vulnerable group. Considering influencing factors, dietary counseling and preventive supplementation therapy for this high risk group of children and adolescents may be necessary, although this should be assessed by intervention studies.

Fulltext Hepatitis C Infection Become a Common Issue Among Hemodialysis Patients in a Hemodialysis Center Jakarta, Indonesia, and Survival Comparison of Hemodialysis Patients with Hepatitis Infection between Two Hemodialysis Centers in Jakarta, Indonesia, and Penang, Malaysia

Ramatillah DL, Syed Sulaiman SA, Khan AH

J Glob Infect Dis, 2018 6 19;10(2):37-41.
PMID: 29910562 DOI: 10.4103/jgid.jgid_85_17

Background: According to the Association of Nephrologist in Indonesia (Pernefri) recommendation, isolation and using special hemodialysis machines are not necessary for hemodialysis (HD) patients who have been infected by hepatitis C virus (HCV), while according to the Ministry of Health Malaysia recommendation, hepatitis C patients should be dialyzed in a separate room or a separate area with a fixed partition and dedicated machines.
Aim: The aim of this study was to identify the correlation between the recommendation which had been followed by two HD centers in different countries and the impact of that on the hepatitis C infection issue.
Methods: A cohort prospective and retrospective study was done in this research. The study included HD patients who were followed up for 9 months and who died in the last 5 years. Universal sampling was used to select the patients based on inclusion criteria.
Results: There was a significant relationship between HCV during the first checkup and HCV during the second checkup during the 9-month follow-up of HD patients in a HD center, Jakarta, Indonesia. The total number of patients who had hepatitis C during the first and second checkups was also different in this HD center.
Conclusion: Besides providing special HD rooms and machines for HD patients with hepatitis C, minimizing blood transfusion to the patients on HD is also important to reduce the chance for the patients to acquire hepatitis C and to increase the percentage of survival.

PMID: 24369358 DOI: 10.1038/jhg.2013.131

Beta-thalassemia is one of the most prevalent inherited diseases and a public health problem in Malaysia. Malaysia is geographically divided into West and East Malaysia. In Sabah, a state in East Malaysia, there are over 1000 estimated cases of β-thalassemia major patients. Accurate population frequency data of the molecular basis of β-thalassemia major are needed for planning its control in the high-risk population of Sabah. Characterization of β-globin gene defects was done in 252 transfusion dependent β-thalassemia patients incorporating few PCR techniques. The study demonstrates that β-thalassemia mutations inherited are ethnically dependent. It is important to note that 86.9% of transfusion-dependent β-thalassemia major patients in Sabah were of the indigenous population and homozygous for a single mutation. The Filipino β(0)-deletion was a unique mutation found in the indigenous population of Sabah. Mutations common in West Malaysia were found in 11 (4.3%) patients. Four rare mutations (Hb Monroe, CD 8/9, CD 123/124/125 and IVS I-2) were also found. This study is informative on the population genetics of β-thalassemia major in Sabah.

Effect of intraoperative autologous transfusion techniques on perioperative hemoglobin level in idiopathic scoliosis patients undergoing posterior spinal fusion: A prospective randomized trial

Hasan MS, Choe NC, Chan CYW, Chiu CK, Kwan MK

J Orthop Surg (Hong Kong), 2017 May-Aug;25(2):2309499017718951.
PMID: 28675975 DOI: 10.1177/2309499017718951

BACKGROUND: Massive blood loss during posterior spinal fusion for adolescent idiopathic scoliosis remains a significant risk for patients. There is no consensus on the benefit of acute normovolemic hemodilution (ANH) or intraoperative cell salvage (ICS) in scoliosis surgery.

METHODS: Patients were randomized to one of two groups. Group A received ANH and ICS during operation, while group B received only ICS. Patients' age, sex, height, weight, body blood volume, number of fusion level, Cobb angle, number of screws, duration of surgery, and skin incision length were recorded. Hemoglobin and hematocrit levels were obtained preoperatively and postoperatively (0 h and 24 h).

RESULTS: There were 22 patients in each group. There was no significant difference in total blood loss. The perioperative decrease in hemoglobin levels between preoperation and postoperation 24 h (group A 2.79 ± 1.15 and group B 2.76 ± 1.00) showed no significant difference ( p = 0.93). Group A observed a larger decrease in hemoglobin levels at postoperative 0 h relative to preoperative level (2.57 ± 0.82 g/dl), followed by a smaller decrease within the next 24 h (0.22 ± 1.33 g/dl). Group B showed a continued drop in hemoglobin levels of similar magnitude at postoperation 0 h (1.60 ± 0.67 g/dl) and within the next 24 h (1.16 ± 0.78 g/dl). One patient from group B received 1 unit of allogenic blood transfusion ( p = 0.33).

CONCLUSIONS: The addition of ANH to ICS in posterior spinal fusion surgery for AIS resulted in a similar decrease in hemoglobin levels between preoperative values and at 24 h postoperatively.

Risks of seroconversion of hepatitis B, hepatitis C and human immunodeficiency viruses in children with multitransfused thalassaemia major

Lee WS, Teh CM, Chan LL

J Paediatr Child Health, 2005 May-Jun;41(5-6):265-8.
PMID: 15953326 DOI: 10.1111/j.1440-1754.2005.00608.x

OBJECTIVES: To estimate the risks of seroconversion of hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency viruses (HIV) in children with multitransfused thalassaemia at a thalassaemic clinic in Kuala Lumpur, Malaysia.
METHODS: Seventy-two children (39 males, median age 11.3 years, 2.5th-97.5th centile: 1.4-19.2 years) with thalassaemia major were studied. The risks of seroconversion of HBV, HCV and HIV were estimated by comparing the seroprevalences of hepatitis B surface antigen (HBsAg), anti-HCV and anti-HIV between a defined starting point and an end point. The end point was the point when latest serological results were available while the starting point was when regular transfusion was commenced, or approximately 5 years before the end point when the duration of transfusion was longer.
RESULTS: The median duration of the study was 49 months (range 8-69 months, total 2953 patient-months). There were 2605 transfusion episodes and 4154 units of blood transfused (0.88 transfusion episode/patient per month, 1.41 units of blood transfused/patient per month). There were three new seroconversions for anti-HCV but none for HBsAg and anti-HIV. The risk of seroconversion for HCV was one in 1384 units of blood transfused (95% CI: 4000-472). The seroprevalence rates at the starting and end points were: HBsAg (1%, 1%), anti-HCV (10%, 13%) and anti-HIV (0%, 0%), respectively.
CONCLUSIONS: The estimated risk of acquiring HCV infection in children receiving multiple blood transfusions in this study is surprisingly higher than the generally accepted estimated risk. Other routes of transmission may be important. A prospective, multicentre study to estimate such risks more precisely is needed.

Post-transfusion hypertension and seizure in congenital hemolytic anemia: a case report and literature review

Ngim CF, Ng CS, Lai NM

J Trop Pediatr, 2014 Jun;60(3):253-6.
PMID: 24473404 DOI: 10.1093/tropej/fmu003

A rare syndrome of hypertension, seizures and intracranial bleed has been reported among patients with congenital hemolytic anemia who underwent multiple blood transfusions. We report this syndrome in a 12-year-old Malay girl with hemoglobin E-beta-thalassemia, who underwent intensive transfusion and subsequently had headache, visual loss, severe hypertension and seizures. A comprehensive literature review revealed 30 patients with this syndrome, of whom 15 had intracranial bleed and 12 among these 15 died. A less-intensive transfusion regimen among patients with chronic hemolytic anemia and prompt detection and management of hypertension may prevent this potentially fatal syndrome.

This review paper aims to present an overview of the development of blood substitute particularly red blood cell substitute or artificial oxygen carrier. Knowledge on human blood inspired from the understanding of human blood circulation system. Ibn Nafis was first to describe that blood flow through respiratory system before entering the heart. This finding denied the claim that tiny pores present within the septum of the heart. Then, William Harvey further described human cardiovascular system in detail and contributed to better understanding on the roles of blood in body. Several blood transfusions were attempted using blood collected from human, animal and other blood substitutes such as milk before the practice was banned for almost 150 years in Europe. Major discoveries on blood group and antibody reaction have made blood transfusion safer. However, several issues and challenges have re-triggered the exploration to develop red cell substitutes. Two approaches have been taken to develop the red blood cell substitute which are classified into biological and chemical based oxygen carriers. The earliest efforts have been on haemoglobin based oxygen carrier (HBOC) and perfluorocarbon (PFC) while the recent developement are on polymer-based oxygen carrier and in-vitro stem cell derived red blood cell.

Prophylactic platelet transfusion plus supportive care versus supportive care alone in adults with dengue and thrombocytopenia: a multicentre, open-label, randomised, superiority trial

Lye DC, Archuleta S, Syed-Omar SF, Low JG, Oh HM, Wei Y, et al.

Lancet, 2017 Apr 22;389(10079):1611-1618.
PMID: 28283286 DOI: 10.1016/S0140-6736(17)30269-6

BACKGROUND: Dengue is the commonest vector-borne infection worldwide. It is often associated with thrombocytopenia, and prophylactic platelet transfusion is widely used despite the dearth of robust evidence. We aimed to assess the efficacy and safety of prophylactic platelet transfusion in the prevention of bleeding in adults with dengue and thrombocytopenia.
METHODS: We did an open-label, randomised, superiority trial in five hospitals in Singapore and Malaysia. We recruited patients aged at least 21 years who had laboratory-confirmed dengue (confirmed or probable) and thrombocytopenia (≤20 000 platelets per μL), without persistent mild bleeding or any severe bleeding. Patients were assigned (1:1), with randomly permuted block sizes of four or six and stratified by centre, to receive prophylactic platelet transfusion in addition to supportive care (transfusion group) or supportive care alone (control group). In the transfusion group, 4 units of pooled platelets were given each day when platelet count was 20 000 per μL or lower; supportive care consisted of bed rest, fluid therapy, and fever and pain medications. The primary endpoint was clinical bleeding (excluding petechiae) by study day 7 or hospital discharge (whichever was earlier), analysed by intention to treat. Safety outcomes were analysed according to the actual treatment received. This study was registered with ClinicalTrials.gov, number NCT01030211, and is completed.
FINDINGS: Between April 29, 2010, and Dec 9, 2014, we randomly assigned 372 patients to the transfusion group (n=188) or the control group (n=184). The intention-to-treat analysis included 187 patients in the transfusion group (one patient was withdrawn immediately) and 182 in the control group (one was withdrawn immediately and one did not have confirmed or probable dengue). Clinical bleeding by day 7 or hospital discharge occurred in 40 (21%) patients in the transfusion group and 48 (26%) patients in the control group (risk difference -4·98% [95% CI -15·08 to 5·34]; relative risk 0·81 [95% CI 0·56 to 1·17]; p=0·16). 13 adverse events occurred in the transfusion group and two occurred in the control group (5·81% [-4·42 to 16·01]; 6·26 [1·43 to 27·34]; p=0·0064). Adverse events that were possibly, probably, or definitely related to transfusion included three cases of urticaria, one maculopapular rash, one pruritus, and one chest pain, as well as one case each of anaphylaxis, transfusion-related acute lung injury, and fluid overload that resulted in serious adverse events. No death was reported.
INTERPRETATION: In adult patients with dengue and thrombocytopenia, prophylactic platelet transfusion was not superior to supportive care in preventing bleeding, and might be associated with adverse events.

ABO blood grouping is an important antigenic blood typing tools in blood transfusion and organ transplants. Mismatching of blood during transfusion would lead to undesired transfusion reactions. Due to rare occurrence of rare blood group such as A2 subtype, regular blood grouping technique would have missed the identification of blood group. Objectives: In this study, the identification of A2 subgroup using routine serological technique was validated via DNA sequencing technique. Materials and Methods: A total of 656 students participated in this study consist of Malay (87.0 %), Chinese (0.4 %), Indian (11.4 %) and others ethnic group (0.9%) respectively. Monoclonal antisera A, B, AB, D, A1 lectin and H lectin were used to identify the antigen on red blood cells. DNA sequence analysis was applied to examine single nucleotide polymorphisms (SNPs) at position 467 (substitution of C>T) and 1061 (deletion of C) on coding region of ABO gene. Results: Our findings showed of 656 blood samples, 256 (39.0%) were blood group O, 190 (29.0%) were blood group B, 179 (27.3%) were blood group A and 31(4.7%) were blood group AB. The frequency of A1 subgroup is 177 (99.0%) and A2 subgroup is 2 (1.0%). From 179 A blood group, only 2 samples showed negative reaction towards anti-A1 lectin. DNA sequence analysis revealed the SNPs at nucleotide 1061 position in sample 2, however this mutation was absence in sample 1, suggesting presence of another mutation that may result in the A2 phenotype. Conclusion: The current study reported the absence of 1061C deletion in A2 blood group sample among Malaysian population.

Malaria may be a serious complication of blood transfusion due to the asymptomatic persistence of parasites in some donors. This case report highlights the transfusion-transmitted malaria of Plasmodium vivax in a child diagnosed with germ cell tumour. This child had received blood transfusion from three donors and a week later started developing malaria like symptoms. Nested PCR and sequencing confirmed that one of the three donors was infected with P. vivax and this was transmitted to the 12-year-old child. To the best of the authors' knowledge, this is the first reported transfusion-transmitted malaria case in Malaysia.

Current issues in the management of thalassaemia

Rahman Jamal

Malaysian Journal of Child Health, 1998;10(1):1-8.

The thalassaemias are the commonest single gene disorders amongst the inherited diseases. In Malaysia, there are an estimated 2200 transfusion dependent thalassaemia patients. With a carrier rate of 3-5%, 120-340 new cases of thalassaemia are expected to be born each year. The reference treatments for these patients are regular blood transfusions and iron chelation therapy. With optimal management, these patients are able to survive into the third or fourth decade of life and most importantly avoid the complications related to transfusions and iron overload. The use of desferal locally is still limited to only those who can afford i.e. about 30% of the cases. Treatment for some of the complications such as hepatitis C, diabetes mellitus, growth impairment and pubertal delay, are now available. Curative treatment approaches like bone marrow transplantation have now become standard treatment for eligible cases whilst cord blood transplantation may yet offer hope for those who are without compatible sibling donors. Research on globin gene therapy looks very promising but will probably take some time to deliver. Hb F switching is a very novel idea but so far the results are mainly anecdotal. Finally, the strive for optimal management of thalassaemia must come hand in hand with a prevention programme to achieve a reduction of new cases.

Introduction: Zika virus is mainly transmitted to human through bite of an infected Aedes species mosquito. It was reported that the transmission also occurs by blood transfusion, sexual intercourse and from mother to foetus. The World Health Organization (WHO) had declared Zika infection outbreak as Public Health Emergency of Internation-al Concern (PHEIC) in February 2016. Since December 2016, total of eight Zika cases had been reported to Ministry of Health, Malaysia (MOH). Since there is no available vaccine and specific treatment for the Zika virus infection, the preventive practices against Zika virus infection is the only defense and method to curb the infection. The ob-jective of this study is to determine predictors of preventive practices towards Zika virus infection among patients attending health clinics in Seremban. Methods: A cross-sectional study was done in selected public health clinics in Seremban, involving 874 respondents recruited by simple random sampling method. Primary data was collected using self-administered questionnaires in English and Bahasa Malaysia. Descriptive and analytical statistics were performed using SPSS version 22.0. Results: Majority of the respondents were female (57.2%), below 40 years old (62.5%), Malay (83.1%), Muslim (83.8%), married (86.2%) and had secondary school education (51.8%), working (64.9%) with monthly household income of

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
