Clinical aspects and genetic heterogeneity of haemoglobin H syndromes in West Malaysia

George-Kodiseri E, Wong HB

Family Physician, 1990;2:43-46.

Clinically, Hb H disease presents as alpha thalassaemia intermedia. The majority have a clinical course of well compensated chronic haemolytic anaemia with exacerbations caused by oxidant haemopoietic stress. Haematological and DNA studies have identified the common molecular defects associated with Hb H disease in West Malaysia. Patients were shown to have Î±0 - thalassaemia of the South-East Asian type (--/SEA) in association with Î±+ thalassaemia or with Hb Constant Spring. In a study of 32 patients with Hb H disease, 50% were shown to have Î±+ thalassaemia (-Î± 3.7, 87.5%; -Î± 4.2, 12.5%). Growth and development were normal in all patients, and cholelithiasis was seen in 50% of the patients with the non-deletional type of Hb H disease. Comparisons of the clinical parameters (the necessity of blood transfusion, thalassaemia facies), haemoglobin and bilirubin levels show that the non-deletional type of Hb H disease in West Malaysia is associated with a more severe clinical state than the deletional type.

Family Physician, 1993;5(2):26-30.

Analysis of the nutritional status and its related factors of three different geographic areas was conducted. The areas were Kampong Sungai Gulang-Gulang, a traditional village in Kuala Selangor, vegetable farming area in Kuala Terla, Cameron Highland and housing flats in Kuala Lumpur. Assessment of nutritional status was done using anthropometric, clinical, biochemical, dietary and stool examination. The results show that 13% of the children in traditional village were stunted, 8% were wasted and 17% were underweight. In vegetable farming area the prevalence were 16.5%, 10.2% and 20.2% respectively. The prevalence of anaemia among toddler was 81.0% in traditional village, 77.2% in vegetable farming area and 55.3% in urban flats. Anaemia in the three areas was strongly associated with inadequate intake of iron.

Fulltext Role of immunopathology in clinical course of malaria: a review

Wynn AA, Myint O

Borneo Journal of Medical Sciences, 2018;12(3):3-10.

MyJurnal

Malaria is a major health problem in various parts of the world especially affecting the tropical countries. It affects the vital organs causing severe complicated malaria. Clinical syndromes like severe cerebral anaemia, coagulation abnormalities, respiratory distress and severe anaemia can increase the mortality of malaria infected cases. Variation in individual susceptibility and severity and type of clinical presentations of malaria raises the need for study of both the parasite and host immune reactions as well as the contribution of inflammatory cytokines in malaria pathogenesis. This study explored the immunopathological basis and advances of severe malaria and their importance in pathogenesis of malaria and its complications. Previous and ongoing studies indicate that changes in endothelium during the sequestration of parasites in organs causes disruption of endothelial barrier function leading to serious effects of malaria. Parasite and host factors contribute to disturbance of cytokine regulation and escape of parasites from the immune system of the host. Immunopathological changes and dysregulation of cytokine production play central role in pathogenesis and disease severity in malaria.

Anaemia in infancy as a presenting feature of hypothyroidism

Harun, F.

Malaysian Journal of Child Health, 1991;3(1):40-44.

MyJurnal

Thyroid hormones mediate the biological activities of almost all organ systems in the body. Patients with a deficiency of these hormones may present with a wide spectrum of clinical symptomatology. This report is of an infant who presented with chronic anaemia which was found to be secondary to hypothyroidism associated with a hypoplastic lingual thyroid gland. Physicians need to be alert to the varied manifestations of hypothyroidism so as to avoid delay in diagnosis and treatment.

Prevention of thalassaemia

George E

Family Practitioner, 1988;11:89-89.

Hereditary haemolytic anaemias, in particular, thalassaemia and the haemoglobinopathies, have been found to be a significant cause of hereditary haemolytic disease in West Malaysia. Theoretically 1 in 2500 marriages are between heterozygotes for beta-thalassaemia and 1 in 10,000 children can be expected to have thalassaemia major. An approach to the prevention of this disease would be public education and identification of carriers: to develop some approach to the identification and genetic counselling of beta-thalassaemia trait.

Intramuscular versus oral iron supplementation in patients on renal replacement therapy receiving erythropoietin

Thiruventhiran T, Ang BB, Tan SY

JUMMEC, 1999;4:110-112.

Anaemia in patients on renal replacement therapy is a cornmon problem and response to treatment with erythropoietin may be limited by functiollal iron deficiency. We recently studied prospectively for 22 weeks the effect of iron supplemetltation via intramuscular and oral vs intramuscular vs oral routes in 16 patients on chronic haemodialysis with renal anaenlia treated with erythropoietin injections. The rise in haemoglobin was significant in all patients except those on intramuscular iron only. This study supports unconfirmed observations that oral iron supplementation may be effective in patients with renal anaemia associated with functional iron deficiency.

Fulltext Myelodysplastic syndrome: a review from University Hospital, Kuala Lumpur

Ng SC, Kuperan P, Bosco J, Menaka N

Singapore Med J, 1990 Apr;31(2):153-8.

PMID: 2196685

Twenty patients with Myelodysplastic Syndrome (MDS) were diagnosed in University Hospital, Kuala Lumpur over a 5 year period. They were subclassified using the French American British (FAB) criteria. 90% of the patients were above 40 years old and the sex ratio was about equal. The predominant presenting symptom was anaemia and there was paucity of physical signs at presentation. Patients with 'aggressive' subtypes of MDS i.e. refractory anaemia with excess blasts (RAEB), refractory anaemia with excess blasts in transformation (RAEB(-)+) and chronic myelomonocytic leukaemia (CMML) had more frequent thrombocytopenia and neutropenia and their marrow pictures frequently had dysmegakaryopoiesis and dysgranulopoiesis as compared to more the "benign" subtypes i.e. refractory anaemia (RA) and refractory leukaemic anaemia with ringed sideroblasts (RARS). Four patients had leukaemic transformation and all of them came from the 'aggressive' subtypes. The current views on treatment of MDS are discussed.

Serum prohepcidin concentrations in rheumatoid arthritis

Jayaranee S, Sthaneshwar P, Sokkalingam S

Pathology, 2009 Feb;41(2):178-82.

PMID: 18972320 DOI: 10.1080/00313020802436840

AIM: Hepcidin, a recently identified peptide, acts as a central regulator of iron metabolism. It is regarded as a factor regulating the uptake of dietary iron and its mobilisation from macrophages and hepatic stores. It is considered as a mediator of anaemia of inflammation. The aim of this study was to assess whether serum prohepcidin concentration is able to distinguish iron deficiency from anaemia of inflammation in patients with rheumatoid arthritis (RA).

METHOD: Blood samples were obtained from 20 healthy blood donors, 30 RA patients who presented with anaemia and 30 patients who had pure iron deficiency anaemia (IDA). The samples were analysed for full blood count, iron, ferritin, transferrin, soluble transferrin receptor and prohepcidin.

RESULTS: The mean prohepcidin level in the control subjects was 256 microg/L. The prohepcidin level was significantly lower in IDA patients (100 microg/L; p < 0.0001) but not significantly different from that of control in RA patients (250 microg/L; p > 0.05). Higher serum soluble transferrin receptor (sTfR) levels were observed in IDA (p < 0.0001) but not in RA compared with that of control (p > 0.05). RA patients were divided into iron depleted and iron repleted subgroups based on the ferritin level. Prohepcidin in the iron depleted group was significantly lower than the iron repleted group and the control (p < 0.0001) and higher levels were observed in the iron repleted group (p < 0.01). sTfR levels in the iron depleted group were significantly higher than the control and the iron repleted patients (p < 0.001). In the iron repleted group, sTfR level was not statistically different from that of control (p > 0.05).

CONCLUSION: Serum prohepcidin is clearly reduced in uncomplicated iron deficiency anaemia. The reduced prohepcidin levels in the iron depleted RA patients suggests that there may be conflicting signals regulating hepcidin production in RA patients. In RA patients who have reduced hepcidin in the iron depleted group (ferritin <60 microg/L) where sTfR levels are increased suggests that these patients are iron deficient. Further studies with a larger cohort of patients are required to substantiate this point.

G6PD deficiency with hemolytic anemia due to a rare gene deletion--a report of the first case in Malaysia

Ainoon O, Boo NY, Yu YH, Cheong SK, Hamidah HN

Hematology, 2006 Apr;11(2):113-8.

PMID: 16753852 DOI: 10.1080/10245330500155184

A 2-year-old Chinese boy was referred to Hospital UKM for investigation of recurrent episodes of dark-coloured urine and pallor since birth. He was born prematurely at 34 weeks gestation and developed severe early-onset neonatal jaundice requiring exchange blood transfusion. Screening at birth showed Glucose-6-phosphate dehydrogenase (G6PD) deficiency. On admission, physical examination revealed pallor, jaundice and mild hepatomegaly. Results of laboratory investigations showed a hemoglobin level of 11.0 g/dl with a hemolytic blood picture, reticulocytosis of 20% and red cell G6PD activity reported as undetectable. The patient's DNA was analysed for G6PD mutations by PCR-based techniques and DNA sequencing and results showed a 24 bp deletion of nucleotide 953-976 in the exon 9 of the G6PD gene. DNA analysis was also performed on blood samples of the patient's mother and female sibling confirming their heterozygous status, although both showed normal red cell G6PD activity levels. The patient was discharged well and his parents were appropriately advised on the condition and the importance of taking folic acid regularly. This is a first case report in Malaysia of G6PD deficiency causing chronic-hemolytic anemia. The rare 24 bp deletion causes the G6PD Nara variant, previously reported only in two other unrelated males, a Japanese and a Portuguese both with chronic hemolytic anemia.

Fulltext Two truncating variants in FANCC and breast cancer risk

Dörk T, Peterlongo P, Mannermaa A, Bolla MK, Wang Q, Dennis J, et al.

Sci Rep, 2019 08 29;9(1):12524.

PMID: 31467304 DOI: 10.1038/s41598-019-48804-y

Fanconi anemia (FA) is a genetically heterogeneous disorder with 22 disease-causing genes reported to date. In some FA genes, monoallelic mutations have been found to be associated with breast cancer risk, while the risk associations of others remain unknown. The gene for FA type C, FANCC, has been proposed as a breast cancer susceptibility gene based on epidemiological and sequencing studies. We used the Oncoarray project to genotype two truncating FANCC variants (p.R185X and p.R548X) in 64,760 breast cancer cases and 49,793 controls of European descent. FANCC mutations were observed in 25 cases (14 with p.R185X, 11 with p.R548X) and 26 controls (18 with p.R185X, 8 with p.R548X). There was no evidence of an association with the risk of breast cancer, neither overall (odds ratio 0.77, 95%CI 0.44-1.33, p = 0.4) nor by histology, hormone receptor status, age or family history. We conclude that the breast cancer risk association of these two FANCC variants, if any, is much smaller than for BRCA1, BRCA2 or PALB2 mutations. If this applies to all truncating variants in FANCC it would suggest there are differences between FA genes in their roles on breast cancer risk and demonstrates the merit of large consortia for clarifying risk associations of rare variants.

Fulltext Induced pluripotent stem cells in research and therapy

Teoh HK, Cheong SK

Malays J Pathol, 2012 Jun;34(1):1-13.

PMID: 22870592 MyJurnal

Induced pluripotent stem cells (iPSC) are derived from human somatic cells through ectopic expression of transcription factors. This landmark discovery has been considered as a major development towards patient-specific iPSC for various biomedical applications. Unlimited self renewal capacity, pluripotency and ease of accessibility to donor tissues contribute to the versatility of iPSC. The therapeutic potential of iPSC in regenerative medicine, cell-based therapy, disease modelling and drug discovery is indeed very promising. Continuous progress in iPSC technology provides clearer understanding of disease pathogenesis and ultimately new optimism in developing treatment or cure for human diseases.

Anaemia is a global health problem including Malaysia. In adults, anaemia may affect work productivity. Iron deficiency anaemia and thalassaemia are common causes of anaemia in Malaysia. However, there is scarcity of data on national prevalence of iron deficiency anaemia and thalassaemia, especially in young adults. This cross sectional study was performed to determine the prevalence of iron deficiency anaemia and thalassaemia among medical students of Universiti Kebangsaan Malaysia Medical Centre (UKMMC).

PMID: 16898972

Myelodysplastic syndrome (MDS) is recognized as a preleukaemic disorder with a variable risk of transformation to acute myeloid leukaemia. Usually the blast cells in leukaemia are transformed after MDS displays a myeloid phenotype. Even though lymphoid progression had been reported previously, most displayed myeloid-lymphoid hybrid or early B phenotype. We report a case of an elderly man who had MDS transformed into Acute Lymphoblastic Leukaemia (ALL:L3) which is a rare lymphoid transformation.

Fulltext Iron-deficiency anaemia and serum ferritin levels in Malaysian women

Goh TH, Hariharan M

Med J Malaysia, 1986 Dec;41(4):300-4.

PMID: 3670151

Serum ferritin and blood haemoglobin levels were studied in 229 women attending a family planning clinic. Ferritin values ranged from 2 to 438 Jlg/l and was skewed with an arithmetic mean of 41.8 and geometric mean of 23.4 flg/l; 26.6% were iron-deficient (ferritin < 12 Jlg/l). Haemoglobin values were normally distributed with a mean of 11. 7 g/dl but 59% were anaemic (Hb < 12 gjdl]. The correlation between ferritin and haemoglobin values was poor (r = 0.147) but almost all women with a haemoglobin below 10 g/dl were iron-deficient. This study reaffirms the need for monitoring iron-deficiency anaemia in apparently healthy women seeking contraception.
