Dyslipidemia in type 2 diabetes mellitus: more atherogenic lipid profile in women

Acta medica Iranica 07/2012; 44:111-118.

ABSTRACT Previous studies have shown that diabetes mellitus (DM) increases the risk of cardiovascular disease in women to a greater extent than in men. It seems that DM may alter lipid profiles more adversely in women compared to men. In this study we evaluated serum lipoprotein differences in type 2 diabetic men and women. The study included 350 type 2 diabetic patients (100 men and 250 women), aged 19-82 years. Demographic data were and biochemistry tests including serum lipoproteins were measured. There was no difference between men and women with respect to duration of DM and type of treatment. Body mass index (BMI), systolic and diastolic blood pressures were significantly higher in women than age matched men. Women also had significantly higher plasma levels of total cholesterol (233.7 vs. 190.3 mg/dl, P < 0.001), triglycerides (219.7 vs. 180.6 mg/dl, P < 0.05), low-density lipoprotein cholesterol (LDL-C) (141.2 vs. 116.1 mg/dl, P < 0.001), high-density lipoprotein cholesterol (HDL-C) (47.1 vs. 39.4 mg/dl, P < 0.001), non-HDL cholesterol (186.1 vs. 150.8 mg/dl, P < 0.05), Lp(a) (50.7 vs. 38.2 mg/dl, P < 0.05) and apo-B (117.6 vs. 101.2 mg/dl, P < 0.001). All types of dyslipidemia were significantly more prevalent in females. Women had higher plasma levels of HDL-C compared to men. Higher prevalence of hypertriglyceridemia in females was due to their higher BMI, and sex was not an independent risk factor for hypertriglyceridemia. Type 2 diabetic women are exposed more profoundly to risk factors including atherogenic dyslipidemia and higher BMI, systolic and diastolic blood pressures compared to men.

    ABSTRACT: Objective: To ascertain trends of lipid abnormalities in Pakistani Type-2 Diabetes Mellitus patients. Methodology: Fasting lipid profiles of 328 outpatient adult type 2 diabetes mellitus patients visiting the Aga Khan University Hospital, from January 2005 to January 2006 were prospectively reviewed and abstracted on a pre-specified proforma. Demographic features, different patterns of dyslipidemia in accordance with specified risk categories, and the proportion of patients with none, one, two, or three lipid values outside clinical targets were noted. The influence of sex on dyslipidemia pattern was also assessed Results: Our patients had higher average HbA1c levels and higher total cholesterol, LDL and lower HDL levels. The triglycerides levels in our female patients were higher. The percentage of our patients with a high-, borderline-, or low-risk LDL cholesterol were 54, 29, and 16%, respectively (P = 0.51). On a percentage basis, 73% were in the high-risk HDL cholesterol group, 18% were in the borderline-risk group and 9% in the low-risk group, respectively (P< 0.0001). Regarding triglyceride concentrations, 16% had high-risk triglyceride levels, 34% were in the borderline-risk category, whereas 50% had a low-risk triglyceride levels (P< 0.0001). Patient proportion with None, One, Two, or Three Values outside clinical targets on percentage basis were 2, 16, 48, and 34%, respectively (P< 0.0001). Women were found to have greater odds of having LDL cholesterol above the target level i.e. >100mg/dl. Conclusion: Combination of high LDL and a low HDL cholesterol level was the commonest pattern of dyslipidemia found. Second was unfavorable levels of all three lipoproteins combined and the third was an isolated increase in LDL cholesterol. A greater proportion of women were found dyslipidemic.

    ABSTRACT: Oligonucleotide conjugates containing acridine and quindoline derivatives linked through a threoninol molecule were synthesized. We showed that these conjugates formed duplexes and quadruplexes with higher thermal stability than the corresponding unmodified oligonucleotides. When acridine is located in the middle of the sequence, DNA duplexes have a similar stability independently of the natural base present in front of acridine. Self-complementary oligonucleotides and thrombin binding aptamers (TBA) carrying the acridine and quindoline molecules are studied by NMR.
