Clonal disorders of LGL may either be CD3+ CD56- or CD3- CD56+ phenotype and these have been designated as T-cell leukaemia (T-LGL) or natural killer cell (NK)-LGL leukaemia respectively. Clonality is usually demonstrated by clonal rearrangement of T-cell receptor gene rearrangement or identified by flowcytometry analysis. Most patients with T-LGL will have an indolent course. In this report we described an aggressiveness of disease in a patient with clonal CD3+ LGL leukaemia whose cells also co-expressed CD56 diagnosed by flowcytometry. The patient responded well to interrupt ALL standard risk protocol however succumbed to her disease while waiting for upfront stem cell transplant. This case highlights on both the classical laboratory findings of rare entity of disease as well as a review of the literature pertaining particularly on its management.

Introduction: Methylenetetrahydrofolate reductase (MTHFR) C677T is involved in folate and homocysteine metabolism. Disruption in the activity of this enzyme will alter their levels in the body. Methodology: This study assessed MTHFR C677T polymorphism and its relationship with serum homocysteine and Bvitamins levels in a sample of Chinese and Malays subjects in UPM, Serdang. One hundred subjects were randomly selected from among the university population. Folate, vitamin B12, B6, and homocysteine levels were determined using MBA, ECLIA, and HPLC, respectively. PCR coupled with HinfI digestion was used for detection of MTHFR C677T polymorphism. Results: The frequency of T allele was higher in the Chinese subjects (0.40) compared to the Malay (0.14). Folate, vitamin B12 and B6 levels were highest in the wild genotype in both ethnic groups. Subjects with heterozygous and homozygous genotype showed the highest homocysteine levels. The serum folate and homocysteine were mainly affected by homozygous genotype. Conclusion: MTHFR C677T polymorphism plays an important role in influencing the folate and homocysteine metabolism.

Plasma cell leukaemia (PCL) is a rare form of malignant plasma cell dyscrasia. It can occur as a primary form without prior evidence of multiple myeloma or as a secondary form which is a terminal event in multiple myeloma. It is characterised by a proliferation of plasma cells in blood and the bone marrow. The outcome of plasma cell leukemia is poor with conventional therapy. Here we illustrate a case of primary plasma cell leukemia complicated by para plegia. The patient initially responded to combination chemotherapy but succumbed to the disease two months after presentation

HbA1c is an established index of glycaemic control and correlates strongly with risk of chronic diabetic complications. However, the accuracy of HbA1c measurement can be affected by many factors, among which is the presence of haemoglobin (Hb) variants. The aim of the study was to determine the percentage of Hb variant detected during HbA1c monitoring in Hospital Kuala Lumpur. The study also analysed non-reportable HbA1c results in the presence of Hb variants. A cross-sectional study using retrospective data of HbA1c results over fi ve months’ period was analysed on Biorad Variant II Turbo, a high performance liquid chromatography (HPLC) assay. The Hb variants were grouped either as HbS, HbC, others (Hb variant apart from HbS or C), and a combination of HbS or C with Others. A total of 11,904 patients were included. Only 2.3% (273) had Hb variants; HbS trait (10.3%), others (89%), and the combination of HbS trait with others (0.7%). No patient with HbC variant or its combination was found. Only 2.2% of those with Hb variant had non-reportable HbA1c. Although the percentage of Hb variants detected during HbA1c analysis and non-reportable HbA1c results were low, their presence should be noted.

Introduction: This is a preliminary result of an on-going randomised cross-over trial to compare the effects of consuming yellowstripe scad (YSS) and salmon, both rich in omega-3 fatty acids, on lipid profile, fasting glucose, body weight status, and blood pressure among healthy overweight adults. Methods: Fifty healthy overweight Malaysians aged 21-55 years were recruited voluntarily through advertisements. During the first period of intervention, subjects were randomised equally to receive eight weeks of either steamed whole YSS fish (YSS group) or salmon fillet (salmon group), three days per week, obtaining approximately 7000 mg EPA+DHA per week. The diets were switched after an eight-week washout period. Lipid profile, fasting glucose, body mass index, and blood pressure were evaluated before and after each intervention period. Results: The mean ages of YSS group (n=25) and salmon (n=25) group were 30.6?±9.1 and 27.9?±7.1 years respectively. Both groups had no statistically significant differences on socio-demographic characteristics (p>0.05). After the first intervention period, there was a significant increase in total cholesterol within the YSS group (p<0.05) but not within the salmon group (p>0.05). Both YSS and salmon groups had significantly higher HDL-cholesterol levels after 8 weeks compared to baseline (p<0.05). There was no significant between-group difference in all the variables after eight weeks (time x group interaction, p>0.05). However, there was a significant effect of time on diastolic blood pressure (p<0.05). Conclusion: These preliminary findings indicate that YSS and salmon may have similar beneficial effects on HDL-cholesterol level among healthy overweight adults. The second intervention period is on-going to confirm these finding

Haemoglobinopathies presenting with erythrocytosis is relatively rare. The clinicians might mistakenly diagnose such patients with other causes of erythrocytosis such as myeloproliferative neoplasm, etc instead of haemoglobinopathies. Here, we described two cases of haemoglobin variant, namely Haemoglobin Johnstown (Hb Johnstown) and Haemoglobin Bethesda (Hb Besthesda) that were detected following various futile investigations for persistent erythrocytosis. For both cases, the two main screening methods used were capillary electrophoresis (CE) and high performance liquid chromatography (HPLC). Approximately 30% of the high affinity haemoglobin (Hb) are not detected by electrophoresis method, however, in some cases, a variant Hb peak can be seen in chromatography method. Thus, a high index of suspicion of such diagnosis is utmost important as to not to miss the definitive diagnostic test by DNA analysis.
