Khoo KL, Tan H, Liew YM

Med J Malaysia, 1997 Mar;52(1):38-52.
PMID: 10968052

Over a thousand subjects who visited a city private medical clinic for health screening and advice were examined for their lipid profile and other cardiovascular risk factors. The mean TC, TG, LDL-C and HDL-C were 5.43, 1.45, 3.61 and 1.15 mmol/l. Their derived ratios viz, TC:HDL-C and LDL:HDL-C were 5.11 and 3.43 respectively. The prevalence of hyperlipidaemia was moderately high. Of the subjects studied 58.5% had elevated serum cholesterol, 14.8% had raised triglycerides, 64.9% had raised LDL-C and 20.8% had low HDL-C. Male subjects generally showed higher mean values and abnormality frequency in TC, TG, LDL-C, TC:HDL-C and LDL:HDL-C as compared to female subjects. Although significant ethnic differences were not detected for certain lipid parameters (e.g. TC, TG and HDL-C), the Indians appeared to have higher mean lipid values (except HDL-C), and higher percentage abnormality for all the lipid parameters as compared to the Chinese and the Malays. In correlation studies, the following lipid parameters:- TC versus TG, LDL-C, TC:HDL-C; TG versus TC:HDL-C and LDL:HDL-C; LDL-C versus TC:HDL-C and LDL:HDL-C; were positively correlated. On the other hand, TC versus HDL-C, TG versus HDL-C, LDL-C and HDL-C, and HDL-C versus TC:HDL-C and LDL:HDL-C were negatively correlated. The coronary risk factors which generally showed positive correlations with lipid parameters were BMI and blood pressure. Positive correlations were also recorded between fasting blood glucose and TG; uric acid with TG, TC:HDL-C and LDL:HDL-C. In contrast, risk factors of negative correlations were observed between HDL-C and the coronary risk factors of BMI, diastolic blood pressure and uric acid. Smoking showed raised per cent lipid abnormality for TG, HDL-C, TC:HDL-C and LDL:HDL-C. Alcohol consumption also increased the mean level and abnormality frequency for TG. The implication of this investigation is discussed.

Fulltext Non-achievement of clinical targets in patients with type 2 diabetes mellitus

Eid M, Mafauzy M, Faridah AR

Med J Malaysia, 2004 Jun;59(2):177-84.
PMID: 15559167 MyJurnal

The study was conducted to determine whether the clinical targets for the control of diabetes recommended by American Diabetes Association can be met in the context of routine diabetes practice. This cross-sectional study was undertaken on 211 type 2 diabetic patients at the Outpatients Diabetes Clinic, Hospital Universisti Sains Malaysia (HUSM) Kubang Kerian, Kelantan between the year 2001-2002. Patients' physical examination and their medical history as well as their family history were obtained by administering a structured questionnaire. Samples of patients' venous blood during fasting were taken and analysed for plasma glucose, glycated haemoglobin and lipid profile. Analysis showed that many patients had comorbidities or complications. A large number of them had poor glycaemic control (73%). Systolic and diastolic blood pressures of 75% and 85% subjects were > or = 130 and > or = 80 mmHg, respectively. Body Mass Index (BMI) values of 66% of the patients were outside the clinical target (BMI > or = 25 in male and > or = 24 kg/m2 in female). The lipid profile showed that 96% of the patients had at least one lipid value outside the clinical target level. In this study, 70% of the patients had total cholesterol > or = 5.2 mmol/L, 87% had LDL cholesterol > or = 2.6 mmol/L, 57% had HDL cholesterol less than the normal range, < or = 1.15 mmol/L in men and < or = 1.4 mmol/L in women, while 46% had triglycerides > or = 1.71 mmol/L. Complications of diabetes were observed in 48% of the total number of patients. As for the patients' systolic blood pressure, age and duration of diabetes were found to have significant effects. Older subjects with a longer duration of diabetes were more hypertensive. Variables that had significant effects on BMI were age, duration of diabetes, glycaemic control and gender. Younger females and newly diagnosed subjects with better glycaemic control (A1C < 7%) were found to have higher BMI values. The overall clinical targets were suboptimal. The prevalence of hyperlipidaemia and hypertension was high. It is imperative that better treatment strategies and methods be adopted to enhance diabetes control and reduce long-term complications of the disease.

Fulltext Effect of therapeutic lifestyle changes on insulin sensitivity of non-obese hyperlipidemic subjects: preliminary report

Al-Mahmood AK, Ismail AA, Rashid FA, Azwany YN, Singh R, Gill G

J Atheroscler Thromb, 2007 Jun;14(3):122-7.
PMID: 17587763 DOI: 10.5551/jat.14.122

AIM: To determine the effects of lipid lowering by TLC on insulin sensitivity and secretory status of non-obese normoglycemic hyperlipidemic subjects.
METHODS: An intervention study was undertaken on 16 non-obese normoglycemic hyperlipidemic subjects. They underwent 6 months of a TLC regimen. Their insulin sensitivity and lipid status were assessed at baseline and after six months. A control group containing 16 age, sex and body mass index (BMI) matched normolipidemic subjects was also enrolled to compare the change in lipid levels and insulin sensitivity in the hyperlipidemic subjects.
RESULTS: The intervention showed significant reductions in insulin resistance (HOMA-IR reduced from 3.8 to 1.4, p<0.001) and improvement of insulin sensitivity (HOMA%S increased from 50.1% to 121.2%, p=0.004) in hyperlipidemic subjects with associated reductions in lipid levels.
CONCLUSION: Lipid lowering in non-obese hyperlipidemic subjects may be associated with improvement of insulin sensitivity.

Maternal lipids are associated with newborn adiposity, independent of GDM status, obesity and insulin resistance: a prospective observational cohort study

Samsuddin S, Arumugam PA, Md Amin MS, Yahya A, Musa N, Lim LL, et al.

BJOG, 2020 03;127(4):490-499.
PMID: 31778255 DOI: 10.1111/1471-0528.16031

OBJECTIVE: To determine the association between maternal lipaemia and neonatal anthropometrics in Malaysian mother-offspring pairs.
DESIGN: Prospective observational cohort study.
SETTING: Single tertiary multidisciplinary antenatal clinic in Malaysia.
POPULATION: A total of 507 mothers: 145 with gestational diabetes mellitus (GDM); 94 who were obese with normal glucose tolerance (NGT) (pre-gravid body mass index, BMI ≥ 27.5 kg/m2 ), and 268 who were not obese with NGT.
METHODS: Maternal demographic, anthropometric, and clinical data were collected during an interview/examination using a structured questionnaire. Blood was drawn for insulin, C-peptide, triglyceride (Tg), and non-esterified fatty acid (NEFA) during the 75-g 2-hour oral glucose tolerance test (OGTT) screening, and again at 36 weeks of gestation. At birth, neonatal anthropometrics were assessed and data such as gestational weight gain (GWG) were extracted from the records.
MAIN OUTCOME MEASURES: Macrosomia, large-for-gestational-age (LGA) status, cohort-specific birthweight (BW), neonatal fat mass (NFM), and sum of skinfold thickness (SSFT) > 90th centile.
RESULTS: Fasting Tg > 95th centile (3.6 mmol/L) at screening for OGTT was independently associated with LGA (adjusted odds ratio, aOR 10.82, 95% CI 1.26-93.37) after adjustment for maternal glucose, pre-gravid BMI, and insulin sensitivity. Fasting glucose was independently associated with a birthweight ratio (BWR) of >90th centile (aOR 2.06, 95% CI 1.17-3.64), but not with LGA status, in this well-treated GDM cohort with pre-delivery HbA1c of 5.27%. In all, 45% of mothers had a pre-gravid BMI of <23 kg/m2 and 61% had a pre-gravid BMI of ≤ 25 kg/m2 , yet a GWG of >10 kg was associated with a 4.25-fold risk (95% CI 1.71-10.53) of BWR > 90th centile.
CONCLUSION: Maternal lipaemia and GWG at a low threshold (>10 kg) adversely impact neonatal adiposity in Asian offspring, independent of glucose, insulin resistance and pre-gravid BMI. These may therefore be important modifiable metabolic targets in pregnancy.
TWEETABLE ABSTRACT: Maternal lipids are associated with adiposity in Asian babies independently of pre-gravid BMI, GDM status, and insulin resistance.

Fulltext Rhabdomyolysis and acute renal failure following a switchover of therapy between two fibric acid derivatives

Kamaliah MD, Sanjay LD

Singapore Med J, 2001 Aug;42(8):368-72.
PMID: 11764054

Drug induced myopathy has been reported with the use of fibric acid derivatives, hydroxymethylglutaryl coenzyme A (HMG-CoA) reductase inhibitors and nicotinic acid. Over the last three decades, hypolipemiants like fibric acid derivatives and statins have been increasingly recognised as causes of rhabdomyolysis and acute renal failure especially during combination therapy and in the presence of underlying renal impairment. We report two cases of bezafibrate-induced rhabdomyolysis in patients with underlying coronary artery disease and pre-existing renal impairment. Both patients developed rhabdomyolysis leading to acute renal failure soon after their hyperlipidaemia treatment was changed from gemfibrozil to bezafibrate. There were no intercurrent illnesses or co-administration of other lipid lowering drugs in both patients. Even though both drugs belong to the same fibric acid derivatives group, these patients developed the complication only after a switchover of therapy.

Fulltext Blood pressure variability and arterial elasticity in hyperlipidaemic subjects

Rafidah HM, Azizi A, Noriah MN

Singapore Med J, 2008 Apr;49(4):297-303.
PMID: 18418521

It is debatable whether the assessment of low density lipoprotein or total cholesterol (TC) alone is sufficient to identify an individual's risk of having myocardial infarction. In the Framingham study, the risk of coronary artery disease was better indicated by an increase in the TC to high density lipoprotein cholesterol (TC: HDL) ratio. The aim of this study is to determine the relationship between blood pressure variability (BPV) and arterial compliances in hyperlipidaemics, which was defined as TC:HDL of more than 5.0 as compared to normolipidaemics.

Fulltext Poor glycemic control in younger women attending Malaysian public primary care clinics: findings from adults diabetes control and management registry

Cheong AT, Lee PY, Sazlina SG, Mohamad Adam B, Chew BH, Mastura I, et al.

BMC Fam Pract, 2013;14:188.
PMID: 24325794 DOI: 10.1186/1471-2296-14-188

BACKGROUND: Women of reproductive age are a group of particular concern as diabetes may affect their pregnancy outcome as well as long-term morbidity and mortality. This study aimed to compare the clinical profiles and glycemic control of reproductive and non-reproductive age women with type 2 diabetes (T2D) in primary care settings, and to determine the associated factors of poor glycemic control in the reproductive age group women.
METHODS: This was a cross-sectional study using cases reported by public primary care clinics to the Adult Diabetes Control and Management registry from 1st January to 31st December 2009. All Malaysian women aged 18 years old and above and diagnosed with T2D for at least 1 year were included in the analysis. The target for glycemic control (HbA1c < 6.5%) is in accordance to the recommended national guidelines. Both univariate and multivariate approaches of logistic regression were applied to determine whether reproductive age women have an association with poor glycemic control.
RESULTS: Data from a total of 30,427 women were analyzed and 21.8% (6,622) were of reproductive age. There were 12.5% of reproductive age women and 18.0% of non-reproductive age women that achieved glycemic control. Reproductive age group women were associated with poorer glycemic control (OR = 1.5, 95% CI = 1.2-1.8). The risk factors associated with poor glycemic control in the reproductive age women were being of Malay and Indian race, longer duration of diabetes, patients on anti-diabetic agents, and those who had not achieved the target total cholesterol and triglycerides.
CONCLUSION: Women with T2D have poor glycemic control, but being of reproductive age was associated with even poorer control. Health care providers need to pay more attention to this group of patients especially for those with risk factors. More aggressive therapeutic strategies to improve their cardiometabolic control and pregnancy outcome are warranted.

Ethnicity and glycaemic control are major determinants of diabetic dyslipidaemia in Malaysia

Ismail IS, Nazaimoon W, Mohamad W, Letchuman R, Singaraveloo M, Hew FL, et al.

Diabet Med, 2001 Jun;18(6):501-8.
PMID: 11472471 DOI: 10.1046/j.1464-5491.2001.00494.x

AIMS: To define the prevalence of dyslipidaemia in young diabetic patients in Peninsular Malaysia and the contributory factors of dyslipidaemia in these subjects.

METHODS: This is a cross-sectional study involving 848 young diabetic patients from seven different centres, with representation from the three main ethnic groups. Clinical history and physical examination was done and blood taken for HbA1c, fasting glucose, total cholesterol, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterol and triglycerides.

RESULTS: The overall lipids were suboptimal, worse in Type 2 diabetes mellitus (DM) patients compared with Type 1 DM patients. Of the Type 2 patients, 73.2% had total cholesterol > 5.20 mmol/l, 90.9% had LDL-cholesterol > 2.60 mmol/l, 52.6% had HDL-cholesterol < 1.15 mmol/l and 27.3% had serum triglycerides > 2.30 mmol/l. There were ethnic differences in the lipid levels with the Malays having the highest total cholesterol (mean 6.19 mmol/l), and the highest LDL-cholesterol (mean 4.16 mmol/l), while the Chinese had the highest HDL-cholesterol (geometric mean 1.24 mmol/l). Ethnicity was an important determinant of total, LDL- and HDL-cholesterol in Type 2 DM, and LDL- and HDL-cholesterol and triglycerides in Type 1 DM. Glycaemic control was an important determinant of total, LDL-cholesterol and triglycerides in both Type 1 and Type 2 DM. Waist-hip ratio (WHR) was an important determinant of HDL-cholesterol and triglycerides in both types of DM. Gender was an important determinant of HDL-cholesterol in Type 2 DM, but not in Type 1 DM. Socioeconomic factors and diabetes care facilities did not have any effect on the dyslipidaemia.

CONCLUSIONS: The prevalence of dyslipidaemia was high especially in Type 2 DM patients. Ethnicity, glycaemic control, WHR, and gender were important determinants of dyslipidaemia in young diabetic patients. Diabet. Med. 18, 501-508 (2001)
