Abstract. The respective effects of serum total T4 concentration and of serum total T3 concentration on serum TSH concentration and on lipid parameters were compared in 84 7- to 16-year-old children of the Northern Zaire goitre endemia classified in group A (T4 > 77 nmol/l and T3 > 1.69 nmol/l), B (low T4, normal T3) and C (low T4, low T3). Mean serum TSH level was normal in group A (2.3 mU/l), it raised to 39.4 mU/l in group B (p < 0.001) and to 166.3 mU/l in group C (p < 0.001 vs A and B). Low density lipoprotein cholesterol and apoprotein B were increased in group B vs A (p < 0.05) and in group C vs A (p < 0.001) and B (p < 0.001 for apoprotein B; not significant for cholesterol). High density lipoprotein cholesterol and apoprotein Al were similar in the three groups. Mean serum triglyceride level, not different in groups A and B, was doubled in group C (p < 0.001). Multiple regression analysis showed that serum TSH, apoprotein B, and triglyceride levels were influenced by both thyroid hormones concentrations with a predominant effect of serum T4 on the first two parameters and of serum T3 on the last one. In conclusion, low serum T4 with normal T3 concentrations resulted in an increase in serum TSH and in an altered lipid metabolism; it clearly represented an hypothyroid state.

Risk Of Preeclampsia

Background: Preeclampsia is associated with adverse pregnancy outcome and is a major cause of the fetomaternal morbidity and mortality. This study aimed at finding the role of lipid profile and uterine artery Doppler as a reliable predictor of risk of preeclampsia in early second trimester.Methods: This study is conducted in the obstetrics and gynecology department of a tertiary care teaching hospital, Amritsar. Lipid profile and Uterine artery doppler is estimated in 100 antenatal women from 14-20 weeks of period of gestation who met the inclusion criteria and are followed up till delivery or till preeclampsia sets in.Results: Out of 100 subjects 74 remained normotensive (Group A) and 26 developed preeclampsia (Group B). The mean serum level of total cholesterol (TC), triglycerides (TG), low density lipoprotein cholesterol (LDL) and very low-density lipoprotein cholesterol (VLDL) was significantly higher in Group B as compared to group A women. The Preeclamptic women showed significant fall in high density lipoprotein cholesterol (HDL) level as compared to normal pregnant women. The mean S/D ratio, PI and RI values of uterine artery Doppler were higher for group B and were statistically significant.Conclusions: The combined predictive value of lipid profile and uterine artery Doppler for estimating risk of preeclampsia was more reliable than of any of the test individually.

Background. Several polymorphisms of a locus on chromosome 1p13.3 have a significant effect on low-density lipoprotein cholesterol (LDL-C), atherosclerosis, and acute coronary syndrome (ACS).Methods. We aimed to investigate the association between rs599839, rs646776, and rs4970834 of locus 1p13.3 and serum LDL-C and severity of coronary artery stenosis in ACS patients. Genotyping of the rs599839, rs646776, and rs4970834 polymorphisms was performed on Arab patients undergoing coronary angiography for ACS. Patients were divided into group A (ACS with insignificant stenosis (<50%)) and group B (with significant stenosis (≥50%)).Results. Patients carrying the minor G allele in rs599839 had significantly lower mean of LDL-C (2.58 versus 3.44 mM,P=0.026) than homozygous A allele carriers (GG versus AA). Carriers of minor C allele in rs64776 had significantly higher mean of HDL-C (2.16 versus 1.36 mM,P=0.004) than carriers of the T alleles (AA versus GG). The odd ratio and 95% confidence interval for dominant model for G allele carriers of rs599839 were 0.51 (0.30–0.92),P=0.038, among patients with significant stenosis.Conclusions. Polymorphisms rs646776 and rs599839 of locus 1p13.3 were significantly associated with LDL-C and other lipid parameters. In addition, the G-allele carriers of variant rs599839 had a significant protective effect against the atherosclerosis.

Background: Obesity has become one of the most important public health problems in recent years. Childhood obesity increases the risk of morbidities such as dyslipidemia, hypertension, type 2 diabetes (T2DM), metabolic syndrome etc. Dyslipidemia pattern consists of a combination of elevated total cholesterol, triglycerides (TG), low density lipoprotein cholesterol (LDL-C) and decreased high density lipoprotein cholesterol (HDL-C). Aim of this study was to assess fasting lipid profile and pattern of dyslipidemia in overweight and obese children in a hospital setting. Methods: It was a cross sectional study done in children, aged 5 to 16 years, attending the paediatric endocrine clinic and paediatric outpatient department, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka over a period of 18 months. All overweight and obese children as well as normal weight children were selected after considering inclusion and exclusion criteria. They were categorised as group A (overweight and obese) and group B (normal weight). Results: In group A, 77.0% of children were obese and 23.0% were overweight. Total cholesterol, LDL and TG were significantly higher in group A (p<0.05). HDL was low in 58.0% of group A and 52.0% of group B which was not significantly different (p>0.05) between the groups. Most of the overweight and obese children had one or two lipid parameters abnormality but majority of normal weight children had one parameter abnormality. Dyslipidaemia was present in 80.0% and 64.0% among group A and group B respectively, which was significantly different (p<0.05). Conclusion: It was observed that 80.0% patients had dyslipidaemia among the overweight and obese children and total cholesterol, low density lipoprotein and triglyceride level were significantly higher in this group.

Background: Current treatment with statins has become an integral part of vascular diseases but monotherapy has a significant residual event rate. Due to particularly one of the factor associated with atherogenic lipid phenotype that is characterized by a low high-density lipoprotein (HDL) cholesterol and increase in non-HDL cholesterol like Low-Density Lipoprotein (LDL). Omega-3 Fatty acids have demonstrated a preventiverole in primary and, particularly secondary cardiovascular diseases.  Hence this study was planned to compare the efficacy of Atorvastatin alone with Atorvastatin and Omega-3 fatty acids in treatment in hyperlipidaemia patients. Methods: The study was comparative, randomized, and prospective and open labeled conducted in MI patients. A total of 100 patients were selected based on inclusion and exclusion criteria. They were divided randomly into two Groups (Group–A and Group-B). Group-A was given Atorvastatin 10mg/day and Group-B was given Atorvastatin 10mg/day and Omega-3 fatty acids 600mg/day for 6 months. Follow up was done every month and efficacy was measured by assessing the lipoprotein levels in serum. Results: The results were compared before treatment and after 6 months treatment.The levels were significantly decreased Total Cholesterol (TC), LDL, Low-Density Lipoprotein (VLDL), Triglycerides (TG) and HDL levels were increased in Group–A and Group-B. When these results compared between two Groups the HDL levels were increased also it shown high significance (<0.001) but there were no significance changes in other cholesterol levels. Conclusion: The present study results showed that Atorvastatin and Omega-3 fatty acids treatment was more effective than Atorvastatin alone treatment in improving HDL-C levels from base line and it may have a additive effect in major coronary artery diseases.

Objective To determine whether lipoprotein abnormalities associated with continuous ambulatory peritoneal dialysis (CAPD) are influenced by residual renal function (RRF). Design Open, non randomized prospective and com -parative study. Setting Single university teaching hospital dialysis unit and outpatient clinic. Patients Twenty adult patients on standard CAPD (1 -38 months) were divided into two groups: group A (RRF ≤ 0.8 mL/min, n = 10) and group B (RRF ≥ 1.1 mL/ min, n = 10). Patients in the two groups were matched for age, time on dialysis, body weight, body mass index, serum urea and albumin levels, peritoneal and urinary albumin losses, and peritoneal transport characteristics such as overnight 8hour peritoneal creatinine and β2-microglobulin clearances and overnight 8-hour effluent glucose concentrations. Results The degree of uremia in patients with preserved RRF (group B) was obviously lower than in patients with negligible RRF (group A), that is, patients in group B had significantly lower serum creatinine and β2-microglobulin levels and significantly higher weekly KTN than group A patients. Despite the prevalence of allele 4 of apolipoprotein E genotype in group A patients, their levels of serum total cholesterol, low-density lipoprotein cholesterol, lipoprotein (a) [Lp(a)], apolipoprotein B (ApoB), and apolipoprotein A1 (ApoA1) were significantly lower than those of patients with preserved RRF (group B). The two groups did not differ significantly in the serum levels of triglyceride or high-density lipoprotein cholesterol. Serum concentrations of Lp(a) and ApoA1, as well as ratios of ApoA1 to ApoB, were correlated significantly with RRF (r = 0.63, r = 0.51, and r = 0.61, respectively). Conclusions The findings suggest that RRF affects the lipid profile of CAPD patients, especially serum levels of cholesterol-rich lipoproteins.

Objective: A modification of Friedewald’s formula was proposed to calculate LDL cholesterol in Bangladeshi population up to serum triglyceride concentration of 1000 mg/dL. The aim of this study was to validate the modification of Friedewald’s formula in Bangladeshi population.Methods: Serum total cholesterol, triglyceride, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol concentrations were measured in specimens obtained form 314 adult Bangladeshi subjects selected conveniently. LDL cholesterol concentrations were also calculated by modified Friedewald’s formula and original Friedewald’s formula. Results were expressed as mean ± SD and calculated LDL cholesterol was compared with measured LDL cholesterol by two-tailed paired t test and Pearson’s correlation coefficient (r).Results: The mean ± SD of measured LDL cholesterol was 138.3 ± 54.58 mg/dL. LDL cholesterol calculated by modified Friedewald’s formula and original Friedewald’s formula were 135.9 ± 59.26 mg/dL (P>0.05) and 123.5 ± 65.75 mg/dL (P<0.001) respectively. Compared to measured LDL cholesterol, calculated LDL cholesterol were 2.47 mg/ dL and 17.20 mg/dL lower for modified formula and original formula respectively. The correlation coefficient (r) with measured LDL cholesterol was 0.8601 (P<0.0001) for LDL cholesterol calculated by the modified Friedewald’s formula and 0.8565 (P<0.0001) for the LDL cholesterol calculated by the original Friedewald’s formula.Conclusion: The study validates the modified Friedewald’s formula to calculate LDL cholesterol in Bangladeshi    population.

Lipid Parameters

Abstract Background Excess adipose tissue is associated with an abnormal lipid profile that may improve with weight reduction. In this meta-analysis, we aimed to estimate the magnitude of change in lipid parameters associated with weight loss in adults who are overweight or obese. Methods We searched MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, and Scopus from 2013 to September, 2018. We included randomized controlled trials (RCTs) that evaluated interventions to treat adult obesity (lifestyle, pharmacologic and surgical) with follow-up of 6 months or more. Results We included 73 RCTs with moderate-to-low risk of bias, enrolling 32 496 patients (mean age, 48.1 years; weight, 101.6 kg; and body mass index [BMI], 36.3 kg/m2). Lifestyle interventions (diet, exercise, or both), pharmacotherapy, and bariatric surgery were associated with reduced triglyceride (TG) and low-density lipoprotein cholesterol (LDL-C) concentrations and increased high-density lipoprotein cholesterol (HDL-C) at 6 and 12 months. The following data are for changes in lipid parameters after 12 months of the intervention with 95% CI. Following lifestyle interventions, per 1 kg of weight lost, TGs were reduced by –4.0 mg/dL (95% CI, –5.24 to –2.77 mg/dL), LDL-C was reduced by –1.28 mg/dL (95% CI, –2.19 to –0.37 mg/dL), and HDL-C increased by 0.46 mg/dL (95% CI, 0.20 to 0.71 mg/dL). Following pharmacologic interventions, per 1 kg of weight lost, TGs were reduced by –1.25 mg/dL (95% CI, –2.94 to 0.43 mg/dL), LDL-C was reduced by –1.67 mg/dL (95% CI, –2.28 to –1.06 mg/dL), and HDL-C increased by 0.37 mg/dL (95% CI, 0.23 to 0.52 mg/dL). Following bariatric surgery, per 1 kg of weight lost, TGs were reduced by –2.47 mg/dL (95% CI, –3.14 to –1.80 mg/dL), LDL-C was reduced by –0.33 mg/dL (95% CI, –0.77 to 0.10 mg/dL), and HDL-C increased by 0.42 mg/dL (95% CI, 0.37 to 0.47 mg/dL). Low-carbohydrate diets resulted in reductions in TGs and increases in HDL-C, whereas low-fat diets resulted in reductions in TGs and LDL-C and increases in HDL-C. Results were consistent across malabsorptive and restrictive surgery. Conclusions Weight loss in adults is associated with statistically significant changes in serum lipids. The reported magnitude of improvement can help in setting expectations, inform shared decision making, and facilitate counseling.
