Fulltext Triglyceride to HDL-C Ratio is Associated with Insulin Resistance in Overweight and Obese Children

Iwani NA, Jalaludin MY, Zin RM, Fuziah MZ, Hong JY, Abqariyah Y, et al.

Sci Rep, 2017 Jan 06;7:40055.
PMID: 28059134 DOI: 10.1038/srep40055

The purpose of this study was to investigate the usefulness of triglyceride to hdl-c ratio (TG:HDL-C) as an insulin resistance (IR) marker for overweight and obese children. A total of 271 blood samples of obese and overweight children aged 9-16 years were analysed for fasting glucose, lipids and insulin. Children were divided into IR and non-insulin resistance, using homeostasis model assessment (HOMA). The children were then stratified by tertiles of TG: HDL-C ratio. The strength between TG:HDL-C ratio and other parameters of IR were quantified using Pearson correlation coefficient (r). Odds ratio was estimated using multiple logistic regression adjusted for age, gender, pubertal stages and IR potential risk factors. Children with IR had significantly higher TG:HDL-C ratio (2.48) (p = 0.01). TG:HDL-C ratio was significantly correlated with HOMA-IR (r = 0.104, p

Fulltext Circulating Metabolic Biomarkers of Screen-Detected Prostate Cancer in the ProtecT Study

Adams CD, Richmond R, Ferreira DLS, Spiller W, Tan V, Zheng J, et al.

Cancer Epidemiol Biomarkers Prev, 2019 Jan;28(1):208-216.
PMID: 30352818 DOI: 10.1158/1055-9965.EPI-18-0079

BACKGROUND: Whether associations between circulating metabolites and prostate cancer are causal is unknown. We report on the largest study of metabolites and prostate cancer (2,291 cases and 2,661 controls) and appraise causality for a subset of the prostate cancer-metabolite associations using two-sample Mendelian randomization (MR).
METHODS: The case-control portion of the study was conducted in nine UK centers with men ages 50-69 years who underwent prostate-specific antigen screening for prostate cancer within the Prostate Testing for Cancer and Treatment (ProtecT) trial. Two data sources were used to appraise causality: a genome-wide association study (GWAS) of metabolites in 24,925 participants and a GWAS of prostate cancer in 44,825 cases and 27,904 controls within the Association Group to Investigate Cancer Associated Alterations in the Genome (PRACTICAL) consortium.
RESULTS: Thirty-five metabolites were strongly associated with prostate cancer (P < 0.0014, multiple-testing threshold). These fell into four classes: (i) lipids and lipoprotein subclass characteristics (total cholesterol and ratios, cholesterol esters and ratios, free cholesterol and ratios, phospholipids and ratios, and triglyceride ratios); (ii) fatty acids and ratios; (iii) amino acids; (iv) and fluid balance. Fourteen top metabolites were proxied by genetic variables, but MR indicated these were not causal.
CONCLUSIONS: We identified 35 circulating metabolites associated with prostate cancer presence, but found no evidence of causality for those 14 testable with MR. Thus, the 14 MR-tested metabolites are unlikely to be mechanistically important in prostate cancer risk.
IMPACT: The metabolome provides a promising set of biomarkers that may aid prostate cancer classification.

Ergün UGO, Oztüzün S, Seydaoglu G

Med J Malaysia, 2004 Aug;59(3):406-10.
PMID: 15727389

To examine a possible association between lipoprotein(a) [Lp(a)] levels and diabetic retinopathy in patients with type 2 diabetes mellitus. 100 type 2 diabetic patients were assessed with the following parameters: age, body mass index, duration of diabetes, blood pressure, fasting plasma glucose, total cholesterol, HDL-cholesterol, triglycerides, blood urea nitrogen, creatinine, Lp(a), and albumin excretion rate (AER). Retinopathy was classified as normal retina (NR), non-proliferative diabetic retinopathy (NPDR), and proliferative diabetic retinopathy (PDR) by an ophthalmologist. The PDR group had higher cholesterol (t=-2.24, p<0.05) and creatinine (z=-2.547, p<0.05) levels than the NPDR group. The PDR group had a higher value of AER (z=-2.439, p<0.01) than the NR group. The possibility of developing diabetic retinopathy after 10 years of diabetes was found to be 6.5 fold high (OR; 6.57, 95% CI 1.74-24.79; p<0.05). The Lp(a) levels were similar in the patients with retinopathy and those without retinopathy. In the study, there was no evidence for a relationship between the serum Lp(a) levels and diabetic retinopathy in type 2 diabetic patients.

Serum osteocalcin in subjects with metabolic syndrome and central obesity

Bador KM, Wee LD, Halim SA, Fadi MF, Santhiran P, Rosli NF, et al.

Diabetes Metab Syndr, 2016 Jan-Mar;10(1 Suppl 1):S42-5.
PMID: 26482049 DOI: 10.1016/j.dsx.2015.09.009

AIMS: The aim of this study was to determine if osteocalcin is related to adiposity and hyperglycaemia in metabolic syndrome irrespective of the presence of diabetes mellitus.
MATERIALS AND METHODS: This was a cross sectional study of 90 patients (59 men and 31 women) with metabolic syndrome as defined by the International Diabetes Federation criteria. Based on medical history 50 out of 90 patients had a diabetes. Anthropometric data were collected and blood taken for measurement of osteocalcin, fasting lipids, fasting glucose and insulin resistance (using homeostatic model assessment index, HOMA-IR).
RESULTS: Osteocalcin correlated negatively with fasting glucose (r=-0.366, p<0.001) and HOMA-IR (r=-0.305, p<0.05) but not with waist circumference (r=0.079), body mass index (r=0.028), total cholesterol (r=0.061) or triglycerides (r=0.009). Diabetics had higher HOMA-IR (p<0.01) and lower osteocalcin levels (p<0.01) than non-diabetics. Among diabetics, osteocalcin correlated with glucose only (r=-0.341, p=0.015). In non-diabetics, osteocalcin correlated with HOMA-IR (r=-0.359, p=0.023) via insulin (r=-0.402, p=0.010). Patients with impaired fasting glucose levels (5.6-6.9mmol/L) had the same HOMA-IR as diabetics (p=0.076) but not low osteocalcin (p=0.025).
CONCLUSIONS: In this cross-sectional study of subjects with metabolic syndrome and central obesity, low osteocalcin was associated with diabetes but not adiposity.

Lie-Injo LE, Caldwell J, Ganesan S, Ganesan J

Cancer, 1976 Jul;38(1):341-5.
PMID: 59626 DOI: 10.1002/1097-0142%28197607%2938%3A1<341%3A%3AAID-C

The level of serum alpha-fetoprotein (AFP) was estimated by radioimmunoassay in 153 normal healthy Malysians of different ethnic groups. The mean level was 7.5 In1/ml (SD 2.28InU/ml). Among 330 patients with malignant tumors, 11 had increased levels of AFP. The only patient who had hepatoma had a very high level of serum AFP. High levels were also found in three of four patients with dysgerminoma of the ovary, in the only two patients with carcinoma of the testis, and in one patient with secondary carcinoma of the humerus of unknown origin. Lower, but significantly increased levels were observed in one patient (of 48) with breast carcinoma, one patient (of 8) with basal cell carcinoma of the nose, one patient (0f 27) with carcinoma of the lung, and one patient (of 59) with nasopharynegeal carcinoma.

Testosterone is the predominant gonadal androgen in men. Low testosterone levels are found to be associated with an increased in metabolic risk and systematic inflammation. Since adipose tissue is a source of inflammatory cytokines, testosterone may regulate inflammation by acting on adipose tissue. This review aimed to explore the role of testosterone in inflammation and its mechanism of action. Both animal studies and human studies showed that (1) testosterone deficiency was associated with an increase in pro-inflammatory cytokines; (2) testosterone substitution reduced pro-inflammatory cytokines. The suppression of inflammation by testosterone were observed in patients with coronary artery disease, prostate cancer and diabetes mellitus through the increase in anti-inflammatory cytokines (IL-10) and the decrease in pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α). Despite these, some studies also reported a non-significant relationship. In conclusion, testosterone may possess anti-inflammatory properties but its magnitude is debatable. More evidence is needed to validate the use of testosterone as a marker and in the management of chronic inflammatory diseases.

Arterial compliance and vitamin E blood levels with a self emulsifying preparation of tocotrienol rich vitamin E

Rasool AH, Rahman AR, Yuen KH, Wong AR

Arch Pharm Res, 2008 Sep;31(9):1212-7.
PMID: 18806966 DOI: 10.1007/s12272-001-1291-5

The tocotrienol vitamin E has potent antioxidant property, however absorption is low due to high lipid solubility. A self emulsifying preparation of tocotrienol rich vitamin E (SF-TRE) had been reported to increase their bioavailability. This randomized, placebo controlled, blinded end point clinical study aimed to determine the effects of 50, 100 and 200 mg daily of SF-TRE and placebo for two months on arterial compliance and vitamin E blood levels. Assessment of arterial compliance by carotid femoral pulse wave velocity (PWV) and augmentation index (AI), plasma vitamin E, serum total cholesterol and low density lipoprotein cholesterol were taken before and after 2 months' treatment in 36 healthy males. Un-supplemented tocotrienol levels were low, after treatment, all SF-TRE treated groups had significantly higher plasma alpha, delta and delta tocotrienol concentrations compared to placebo. Augmentation index change from baseline to end of treatment for groups placebo, 50, 100, and 200 mg were 2.22+/-1.54, -6.59+/-2.84, -8.72+/-3.77, and -6.27+/-2.67% respectively (p=0.049, 0.049, and 0.047 respectively). Groups 100 and 200 mg showed significant improvement after treatment with pulse wave velocity reductions of 0.77 m/s and 0.65 m/s respectively (p=0.007 and p=0.002). There was no effect of SF-TRE on serum lipids. We conclude that there was a trend towards improvement in arterial compliance with 2 months' of SF-TRE.

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.

Influence of dietary fat on plasma lipid profiles of Malaysian adolescents

Marzuki A, Arshad F, Razak TA, Jaarin K

Am J Clin Nutr, 1991 04;53(4 Suppl):1010S-1014S.
PMID: 1901440 DOI: 10.1093/ajcn/53.4.1010S

We studied the effects of saturated (palm olein) and polyunsaturated (soybean oil) cooking oils on the lipid profiles of Malaysian male adolescents eating normal Malaysian diets for 5 wk. Diets cooked with palm olein did not significantly alter plasma total-cholesterol, LDL cholesterol, and HDL cholesterol concentrations or the ratio of total cholesterol to HDL cholesterol compared with diets cooked with soybean oil. However, the diet cooked with palm olein significantly increased apolipoprotein A-I (11%) and apolipoprotein B (9%) concentrations. Unexpectedly, soybean-oil-cooked diets caused a significant increase (47%) in plasma triglycerides compared with palm-olein-cooked diets. We conclude that palm olein, when used as cooking oil, has no detrimental effects on plasma lipid profiles in Malaysian adolescents.

Antinuclear antibodies predict a higher number of pregnancy loss in unexplained recurrent pregnancy loss

Sakthiswary R, Rajalingam S, Norazman MR, Hussein H

Clin Ter, 2015;166(2):e98-101.
PMID: 25945451 DOI: 10.7417/CT.2015.1827

OBJECTIVE: The etiology of recurrent pregnancy loss (RPL) is unknown in a significant proportion of patients. Autoimmune processes have been implicated in the pathogenesis. The role of antinuclear antibody (ANA) in this context is largely undetermined. In an attempt to address the lack of evidence in this area, we explored the clinical significance of antinuclear antibody (ANA) in unexplained RPL.
MATERIALS AND METHODS: We studied 68 patients with RPL and 60 healthy controls from September 2005 to May 2012. All subjects were tested for ANA by immunofluorescence testing, and a titer of 1: 80 and above was considered positive. We compared the pregnancy outcome between the ANA positive and ANA negative RPL cases.
RESULTS: The incidence of ANA positivity among the cases (35.3%) was significantly higher than the controls (13.3%) (p=0.005). ANA positive cases showed significantly higher number of RPL (p=0.006) and lower number of successful pregnancies (p=0.013) compared to the ANA negative cases . The ANA titre had a significant association with the number of RPL (p<0.05, r=0.724) but not with the number of successful pregnancies (p=0.054).
CONCLUSIONS: ANA positivity predicts a less favorable pregnancy outcome in RPL. Our findings suggest that the ANA titre is a useful positive predictor of the number of RPL. Hence, ANA test is a potential prognostic tool for this condition which merits further research.

Yuen KH, Choy WP, Tan HY, Wong JW, Yap SP

J Pharm Biomed Anal, 2001 Feb;24(4):715-9.
PMID: 11272330

A simple high-performance liquid chromatographic method was developed for the determination of omeprazole in human plasma. Omeprazole and the internal standard, chloramphenicol, were extracted from alkalinized plasma samples using dichloromethane. The mobile phase was 0.05 M Na2HPO4-ACN (65:35, v/v) adjusted to pH 6.5. Analysis was run at a flow rate of 1.0 ml/min at a detection wavelength of 302 nm. The method was specific and sensitive with a detection limit of 2.5 ng/ml at a signal-to-noise ratio of 4:1. The limit of quantification was set at 5 ng/ml. The calibration curve was linear over a concentration range of 5-1280 ng/ml. Mean recovery value of the extraction procedure was about 96%, while the within and between day coefficient of variation and percent error values of the assay method were all less than 14%.

PMID: 10968047

Autoantibodies have been known to be detected during pregnancy. The occurrence of autoantibodies during pregnancy was studied in a group of 146 healthy pregnant women from Jan-March 1995. Serum samples were tested for antinuclear (ANA), anti-ds DNA, anti-mitochondrial, anti-smooth muscle and anti-parietal cell antibodies employing the technique of indirect immunofluorescence. Sera from 66 non-pregnant women were used as controls. Among the pregnant group, 2 (1.4%) were found to have ANA positivity in comparison to none in the control group. This difference was found to be not statistically significant. Only 1 (0.7%) was positive for anti-mitochondrial antibody in the pregnant group compared to one in the control group (p > 0.05). However, anti-ds DNA, anti-smooth muscle and anti-parietal cell antibodies were not detected in both groups. All those positive for autoantibodies were in their 2nd trimester. When these cases were followed-up at the end of their pregnancy, none had complicated pregnancies nor infant abnormalities. Our findings suggest that (a) the occurrence of autoantibodies in pregnant women was not significantly different from non-pregnant controls and that (b) maternal autoantibodies did not appear to cause complications during pregnancy or infant morbidity.

Fulltext Suggestion of an active transport of iron to the fetus in human pregnancy and its dependence on maternal serum iron levels

Ali J, Hassan K, Arshat H

Med J Malaysia, 1981 Dec;36(4):215-9.
PMID: 7334956

The present findings suggest the possible involvement of an active mechanism for transport of iron to the fetus. In all the 19 subjects studied, the cord serum iron levels tended to be higher (129.2 ± 56.8 ug/100ml) than the maternal serum iron levels (74.0 ± 35.9 ug/100ml) at parturition even in maternal iron deficiency. The significant difference (P< 0.001) between cord serum iron levels and the maternal iron levels shows that an active transport mechanism working against a gradient in favour of the fetus exists. The availability of iron to the fetus appears to be dependent on maternal serum iron levels but not on maternal iron stores. This finding serves to stress the importance of iron supplements in pregnancy. A hypothetical model for iron transfer from maternal circulation to fetal circulation is described.

Fulltext The variability of blood pressure following repeated measurements

Singh HJ, Singh R, Sirisinghe RG, Upadaya S

Med J Malaysia, 1991 Dec;46(4):356-62.
PMID: 1840445

Two series of Blood Pressure (BP) measurements were carried out to assess the variability in BP following repeated measurements in normotensive individuals. In one series, measurement of BP on three occasions three and seven days apart revealed a significant drop in BP in unaccustomed subjects ('untrained'). In a second series assessing the significance of time-interval between measurements or the number of measurements, it was found that a significant fall in BP occurred over the first four days in 'untrained' individuals, whose blood pressure was measured repeatedly for five consecutive days. A significant positive correlation was evident between the falls in systolic and diastolic pressures and the pressure at first screening. Assessment of the anxiety status revealed a significantly lower state anxiety in 'trained' subjects. It therefore appears that (a) BP in normotensive individuals previously unaccustomed to BP measurements, drops significantly with repeated measurements, (b) the number of measurements seem more important than the time-interval between measurements, (c) the largest falls occur in individuals with high initial pressures and (d) the fall upon repeated measurements may be due to reduced anxiety as familiarity with the procedure makes the subjects comparatively relaxed and less state anxious.

Fulltext Plasma cholesterol and coronary artery disease: how big a heartache?

Lyn PCW

Med J Malaysia, 1987 Mar;42(1):22-30.
PMID: 3323859

Coronary atheroma is the principal cause of ischaemic heart disease. Among the factors considered to predispose to atheroma formation is raised plasma cholesterol and although it is regarded as a minor risk factor by some, others see its contribution as one of major importance. Whichever the view, the debate on plasma cholesterol and coronary heart disease (CHD) has long moved out of the exclusive domain of the scientific journal to the public arena and is reflected in the increasing frequency with which doctors are consulted by patients on the subject. The incidence of CHD in South-East Asian countries is also rising. For the practising clinician, the problem resolves itself into deciding if the evidence incriminating plasma cholesterol as a predisposing factor is strong enough, and if it is, what prophylactic and therapeutic steps are of value in reducing the incidence of CH D. An updated and brief review of lipid metabolism and the relationship of lipids to CHD is now necessary in view of the rapid accumulation of data from recent trials and prospective studies.

Dengue virus is one of the most widespread flaviviruses that re-emerged throughout recent decades. The progression from mild dengue to severe dengue (SD) with the complications such as vascular leakage and hemorrhage increases the fatality rate of dengue. The pathophysiology of SD is not entirely clear. To investigate potential biomarkers that are suggestive of pathogenesis of SD, a small panel of serum samples selected from 1 healthy individual, 2 dengue patients without warning signs (DWS-), 2 dengue patients with warning signs (DWS+), and 5 patients with SD were subjected to a pilot analysis using Sengenics Immunome protein array. The overall fold changes of protein expressions and clustering heat map revealed that PFKFB4, TPM1, PDCL3, and PTPN20A were elevated among patients with SD. Differential expression analysis identified that 29 proteins were differentially elevated greater than 2-fold in SD groups than DWS- and DWS+. From the 29 candidate proteins, pathways enrichment analysis also identified insulin signaling and cytoskeleton pathways were involved in SD, suggesting that the insulin pathway may play a pivotal role in the pathogenesis of SD.

RELATIONSHIP BETWEEN CARBOHYDRATE METABOLISM VALUES AND CALPROTECTIN LEVELS IN PATIENTS WITH ACUTE MYOCARDIAL INFARCTION WITH REGARD TO CONCOMITANT TYPE 2 DIABETES MELLITUS

Zhuravlova M, Ryndina N, Kravchun P

PMID: 30829588

According to literature, the presence of concomitant diabetes mellitus type 2 (DM) is associated with a high frequency of complications in patients with acute myocardial infarction (MI) due to the development of repeated episodes of myocardial ischemia, left ventricular dysfunction, life threatening rhythm disorders, and thromboembolic events Aim: to analyze the state of immuno-inflammation based on the study of calprotectin, as well as to assess the presence and nature of links with carbohydrate metabolism parameters based on the study of blood glucose, insulin and insulin resistance. Patients with AMI in combination with DM 2 were found to have a significant increase in the level of calprotectin by 25.9% (p<0.001) compared to patients with AMI without DM 2. Assessment of carbohydrate metabolism rates revealed changes in the form of statistically significant increase in the concentration of fasting glucose in patients with AMI in combination with DM 2 by 41.8% (p<0.001) when compared to patients with isolated AMI. As for serum insulin, the level of this parameter when combined with the course of AMI and DM 2 significantly exceeded those in patients with AMI without DM 2. The level of HOMA index in patients with AMI with concomitant DM 2 when compared to patients with isolated AMI was also higher (differences are statistically significant, p<0.01). The study showed a correlation between serum calprotectin and insulinemia (R=0.57; p<0.05), HOMA index (R=0.52; p<0.05), fasting glycemia (R=0.59; p<0.05) and troponin I level (R=0,64; p<0,05). The obtained results indicate that the growth of immune inflammatory activity due to the proinflammatory parameter of calprotectin is accompanied by an increase in changes in carbohydrate homeostasis in the form of an increase in the degree of insulin resistance in patients with AMI and DM 2, and severity of cardiac ischemia.

Determination of pyronaridine in blood plasma by high-performance liquid chromatography for application in clinical pharmacological studies

Jayaraman SD, Ismail S, Nair NK, Navaratnam V

J Chromatogr B Biomed Sci Appl, 1997 Mar 07;690(1-2):253-7.
PMID: 9106050

A method is described for the determination of pyronaridine in plasma using high-performance liquid chromatography with fluorescence detection. The method involves liquid-liquid extraction with phosphate buffer (pH 6.0, 0.05 M) and diethyl ether-hexane (70:30%, v/v) and chromatographic separation on a C18 column (Nucleosil, 250 x 4.6 mm I.D., 5 microns particle size) with acetonitrile-0.05 M phosphate buffer pH 6.0 (60:40%, v/v) as the mobile phase (1 ml/min) and detection by fluorescence (lambda ex = 267 nm, lambda em = 443 nm). The detector response is linear up to 1000 ng and the overall recoveries of pyronaridine and quinine were 90.0 and 60.3%, respectively. The assay procedure was adequately sensitive to measure 10 ng/ml pyronaridine in plasma samples with acceptable precision (< 15% C.V.). The method was found to be suitable for use in clinical pharmacological studies.
