Abstract
Objective The objective of this study was to analyze the demographic profile of type 2 diabetes mellitus (DM) patients presenting to a tertiary care hospital of Southern Punjab, Pakistan. Methods This descriptive study was carried out at the Diabetic Outdoor Nishtar Hospital Multan from 2013 to 2018 after taking approval from the Institutional Ethical Review Committee. All patients were evaluated in detail after obtaining informed consent. Results Data of 4,556 patients with type 2 DM were analyzed. There were 2549 (55.9%) female and 2007 (44.1%) male participants in our study. The mean age of our study population was 47.72 years with a standard deviation (SD) of 10.82 years. Seventy-nine percent of the patients belonged to urban areas. Symptoms of polyuria, polydipsia, and polyphagia were found in 72%, 67%, and 59% of patients, respectively. Hypertension was found in 3391 (74%) patients. The mean waist circumference (WC) was 102.85 cm with an SD of 18.14 cm. The mean waist to hip ratio (WHR) was 1.02 with an SD of 0.102. The mean body mass index (BMI) was 26.50 with an SD of 5.57 kg/m2. Obesity (BMI >27 kg/m2) was found in 1,891 (41.5%) of patients. Central obesity was found in 80.7% and 94.7% of type 2 DM patients according to the WC and WHR cutoff, respectively. Females were more likely to be obese than males in all parameters of obesity. Central obesity was much more common in female diabetics as compared to male diabetics (odds ratio 4 in WHR criteria versus odds ratio 1.8 in BMI criteria for obese). Conclusion Diabetes is more prevalent in females than males and especially affects the middle age group. Hypertension and obesity are important comorbid associations of DM. WC and WHR are more reliable indicators of obesity in type 2 DM patients especially in this part of the world. Central obesity was more prevalent in female type 2 DM patients.

Abstract
In order to assess the effect of glycaemic improvement on lipoprotein concentrations, we studied 73 type 2 diabetic subjects before (HbA1c 10.1 (6.2-16)%) and after (HbA1c 6.6 (3.8-8.0)%) glycaemic improvement. Total triglyceride and cholesterol (c), LDLc, HDLc, non-HDLc and apolipoproteins AI (apoAI) and B (apoB) were measured. Bivariate correlations and step-wise, multivariate analysis were performed to find predictors of change in the different components of diabetic dyslipidaemia. Changes in HDLc (r = -0.358, P = 0.001), apoAI (r = -0.355, P = 0.003), apoAI/apoB ratio (r = -0.333, P = 0.005), weight (r = -0.245, P = 0.046) and BMI (r = -0.253, P = 0.039) correlated with that of HbA1c, but, in multivariate analysis, only changes in HDLc, apoAI and apoAI/apoB ratio were predicted by the decrease in HbA1c. For the median observed change in HbA1c (-3.3 percentage-points), the estimated changes were +0.14 mmol/l, +0.12 g/l and +0.20 for HDLc, apoAI and apoAI/apoB ratio, respectively, accounting for 81, 92 and 80% of the observed changes. In conclusion, for the component of diabetic dyslipidaemia for which less therapeutic tools are available, glycaemic improvement is most effective.

Abstract
The current study sought to assess the effect of improving glycemic control in type 2 diabetes on the components of diabetic dyslipidemia, especially low-density lipoprotein (LDL) size. A total of 33 type 2 diabetic patients (48.5% women, age 59.6 +/- 11.1 years, body mass index [BMI] 28.9 +/- 4.9, diabetes duration 6 [0 to 40] years, 40.7% on insulin) were seen at the hospital because of poor glycemic control (hemoglobin A(1c) [HbA(1c)] 10.33% +/- 1.89%). Triglyceride, LDL-cholesterol (LDLc, Friedewald/ ultracentrifugation), high-density lipoprotein HDL-cholesterol (HDLc, direct method), apolipoproteins AI (apoAI) and B (apoB) (immunoturbidimetry), and LDL size (gradient gel electrophoresis) were measured at baseline and after improvement in glycemic control (decrease >/= 1 percentage point in HbA(1c) and final HbA(1c) </= 8%). Improvement in glycemic control (HbA(1c) 7.01% +/- 0.63%, P <.0005 v baseline) after a follow-up of 3.5 (range, 1 to 13) months resulted in a significant reduction in LDLc (3.34 +/- 1.02 v 3.62 +/- 1.15 mmol/L, P <.05) and apoB (1.07 +/- 0.25 v 1.17 +/- 0.29 g/L, P <.01) and an increase in HDLc (1.21 +/- 0.32 v 1.13 +/- 0.34 mmol/L, P <.05) and apoAI (1.36 +/- 0.24 v 1.27 +/- 0.24 mmol/L, P < 0.01) in the whole group, and an increase in LDL particle size (25.61 +/- 0.53 v 25.10 +/- 0.31 nm, P <.005) in the 14 patients showing LDL phenotype B at baseline. No significant changes were seen in body weight or BMI. We conclude that improvement of glycemic control in type 2 diabetes improves most of the components of diabetic dyslipidemia, including a shift towards larger LDL particles in subjects with phenotype B.

Abstract
The aim of the study was to determine if rosiglitazone increases serum levels of lipoprotein(a) [Lp(a)] in Korean patients with type 2 diabetes mellitus. A total of 118 patients were divided into 2 groups: those with rosiglitazone (rosiglitazone group, n = 49) and those without rosiglitazone (control group, n = 69). The rosiglitazone group was given rosiglitazone (4 mg/d) with previous treatment, insulin, or sulfonylurea, for 12 weeks, whereas the control group continued previous treatment with some dose modification for glycemic control. The patients had their blood glucose, lipid levels, as well as Lp(a) levels assessed to obtain a baseline, which were remeasured 12 weeks later. The fasting blood glucose and glycosylated hemoglobin (HbA(1c)) levels decreased significantly in both groups as compared with the baseline. The fasting glucose and HbA(1c) levels in both groups were similar at 12 weeks. The total cholesterol levels increased significantly in the rosiglitazone group (190.6 +/- 32.4 to 212.2 +/- 47.2 mg/dL, P =.002), while they were unchanged in the control group (185.4 +/- 36.8 to 188.0 +/- 35.8 mg/dL, P =.615). The triglyceride levels did not change in either group. Significant increases in high-density lipoprotein (HDL) cholesterol levels were observed in the rosiglitazone group as compared with the baseline (41.7 +/- 10.6 to 45.9 +/- 11.4 mg/dL, P =.004). The low-density lipoprotein (LDL) cholesterol levels increased significantly in the rosiglitazone group (120.5 +/- 29.9 to 136.3 +/- 40.0 mg/dL, P =.012), while they did not change in the control group (113.0 +/- 29.1 to 118.3 +/- 31.7 mg/dL, P =.234). Significant increases in Lp(a) levels were observed in the rosiglitazone group as compared with the baseline (22.4 +/- 17.4 to 25.7 +/- 20.5 mg/dL, P =.015), approximately a 15% increase in average values. In contrast, there was no change in Lp(a) levels in the control group. There was no correlation between the changes in Lp(a) and changes in fasting blood glucose or HbA(1c) levels in all study subjects. In summary, rosiglitazone increased serum total cholesterol, LDL cholesterol, as well as Lp(a) levels in patients with type 2 diabetes mellitus. Considering that patients with type 2 diabetes mellitus have increased risks for cardiovascular disease, caution should be taken when prescribing rosiglitazone to patients who already have other risk factors, such as hypertension and smoking.

Abstract
We investigated alterations of serum levels of Lp(a) and lipid profiles in type 2 diabetic patients and their normoglycemic first-degree relatives to evaluate the potential genetic association among these subjects. Serum Lp(a), triglycerride (TG), total cholesterol (TC), high density lipoprotein-cholesterol (HDL-C), and low density lipoprotein (LDL-C) levels were analyzed in 62 type 2 diabetic patients and 67 normoglycemic first-degree relatives from 29 type 2 diabetic pedigrees, and 45 healthy controls without family histories of diabetes. Dyslipidemia was observed in diabetics and their normoglycemic first-degree relatives. While higher serum TG levels were observed in both type 2 diabetics and their first-degree relatives than those in controls, higher TG levels in diabetics were found when compared with those in first-degree relatives. Meanwhile, lower serum HDL-C levels were observed in both type 2 diabetic patients and their first-degree relatives than those in controls. No significant difference of serum TC and LDL-C levels was found among the three groups. On the other hand, we did not observe significant differences of serum Lp(a) levels between type 2 diabetic patients and normoglycemic first-degree relatives, nor were any significant differences observed between diabetic patients and healthy controls (24.6+/-19.9 vs. 25.8+/-21.2, and 21.3+/-20.5 mg/dl). Although the average serum Lp(a) levels were similar in all subgroups, we did observe a positive correlation of Lp(a) between type 2 diabetic patients and their offspring (r=0.448, P<0.01), suggesting a potential genetic control for Lp(a) levels in type 2 diabetics families.

Abstract
To evaluate the effect of physical exercise on blood pressure, the lipid profile, lipoprotein(a) (Lp(a)), and low-density lipoprotein (LDL) modifications in untrained diabetics, 27 diabetic patients (14 type 1 and 13 type 2) under acceptable and stable glycemic control were studied before and after a supervised 3-month physical exercise program. Anthropometric parameters, insulin requirements, blood pressure, the lipid profile, Lp(a), LDL composition, size, and susceptibility to oxidation, and the proportion of electronegative LDL (LDL(-)) were measured. After 3 months of physical exercise, physical fitness improved (maximal O2 consumption [VO2max], 29.6 +/- 6.8 v 33.0 +/- 8.4 mL/kg/min, P < .01). The body mass index (BMI) did not change, but the waist circumference (83.2 +/- 11.8 to 81.4 +/- 11.2 cm, P < .05) decreased significantly. An increase in the subscapular to triceps skinfold ratio (0.91 +/- 0.37 v 1.12 +/- 0.47 cm, P < .01) and midarm muscle circumference ([MMC], 23.1 +/- 3.4 v 24.4 +/- 3.7 cm, P < .001) were observed after exercise. Insulin requirements (0.40 +/- 0.18 v 0.31 +/- 0.19 U/kg/d, P < .05) and diastolic blood pressure (80.2 +/- 10 v 73.8 +/- 5 mm Hg, P < .01) decreased in type 2 diabetic patients. High-density lipoprotein cholesterol (HDL-C) increased in type 1 patients (1.48 +/- 0.45 v1.66 +/- 0.6 mmol/L, P < .05), while LDL cholesterol (LDL-C) decreased in type 2 patients (3.6 +/- 1.0 v3.4 +/- 0.9 mmol/L, P < .01). Although Lp(a) levels did not vary in the whole group, a significant decrease was noted in patients with baseline Lp(a) above 300 mg/L (mean decrease, -13%). A relationship between baseline Lp(a) and the change in Lp(a) (r = -.718, P < .0001) was also observed. After the exercise program, 3 of 4 patients with LDL phenotype B changed to LDL phenotype A, and the proportion of LDL(-) tended to decrease (16.5% +/- 7.4% v 14.0% +/- 5.1%, P = .06). No changes were observed for LDL composition or susceptibility to oxidation. In addition to its known beneficial effects on the classic cardiovascular risk factors, regular physical exercise may reduce the risk of cardiovascular disease in diabetic patients by reducing Lp(a) levels in those with elevated Lp(a) and producing favorable qualitative LDL modifications.

Abstract
AIMS To examine whether long-term glycaemic control affects lipoprotein(a) (Lp(a)) levels in patients with Type 2 diabetes mellitus. METHODS Eighty-nine Type 2 diabetic patients (38 men, 51 women) were recruited from the diabetes clinic. Based on HbA1c concentrations at baseline, patients were divided into two groups: those with HbA1c < 8.0% (n =45) and those with HbA1c > or = 8.0% (n=44). Comparisons of Lp(a) levels were made between both groups. The effect of long-term glycaemic control on Lp(a) levels was investigated in a subgroup of 20 patients, selected from those with baseline HbA1c > or = 8%. All these patients were treated with a goal of HbA1c <7%. RESULTS Lp(a) levels were not significantly different between those with HbA1c< 8.0% and those with HbA1c, > or = 8.0%. No correlation between Lp(a) and HbA1c or fasting blood glucose levels was noted in diabetic patients as a whole. After 2 years of intensive glycaemic control, all patients exhibited remarkable improvement of therapy: their average HbA1c levels were 6.5 +/- 0.7%, being < 7% in 70% of patients. However, no change in Lp(a) levels were observed after 2 years (19.5 +/- 14.8-21.4 +/- 13.4 mg/dl, P = 0.390). CONCLUSION These results indicate that improvement of glycaemic control does not affect serum Lp(a) levels in patients with Type 2 diabetes mellitus.
