Combined Military Hospital Multan Pakistan, *Pakistan Armed Forces Base Samunigli Quetta Pakistan ABSTRACT
Objective: To study effect of Pioglitazone on serum high density lipoprotein levels in patients with type 2
diabetes mellitus.
Study Design: Single blind randomized controlled trial
Place and Duration of Study: Department of medicine, Combined Military Hospital Multan from 1st Feb 2011
to 30th July 2012.
Material and Methods: A total of 276 already diagnosed patients of diabetes mellitus type 2 between age of
30-80 years, presenting to the outpatient department of Combined Military Hospital Multan were selected.
Type 2 diabetic patients were allocated group A or B using random allocation. Base line blood sugar fasting
(BSF), glycosylated hemoglobin (HbA1c), high density lipoprotein (HDL) levels were taken. Group A was
treated with Pioglitazone along with other hypoglycemic agents while group B was treated with only
hypoglycemic agents and multivitamin tablets were added as placebo.After 12 weeks of treatment, serum
HDL levels were measured to analyze effect of pioglitazone on serum HDL levels.
Results: Pioglitazone group showed significant improvement in the serum HDL levels from baseline HDL
46.38 + 6.44mmol/L to 49.80+ 5.86 mmol/L after 12 weeks of therapy, (p = 0.001).
Conclusion: Pioglitazone when used in combination with other oral hypoglycemic agents has a beneficial
effect on the serum HDL levels of the diabetics.
Keywords: Diabetes Mellitus, High density lipoprotein, Pioglitazone.

So understanding the lipid were collected using full aseptic measures and abnormalities that affect your population group samples were transported to Pathology and having tools and measure to correct them laboratory for analysis. Serum HDL level becomes more important. Decreased serum estimation was done by a timed endpoint HDL levels is one of the commonest lipid method using HDLD reagent. DXC 600 abnormality encountered in Pakistani diabetic automated analyzer was used. The results were populatiPioglitazone is a relatively newer verified by pathologist. GLU reagent was used treatment modality in Pakistan and very little to measure serum glucose levels using DXC-600 work had been done on it, particularly in our automated analyzer. All the data had been population. Pioglitazone has shown many entered in computer software Statistical beneficial effects in the treated diabetic Package for Social Sciences (version 17.0). Mean population and better serum HDL profile is one and standard deviation (SD) were calculated for of major benefits derived from this therapy. all the quantitative variables i.e. age, BMI, Patients with Diabetes Mellitus frequently glycosylated hemoglobin, fasting blood sugar encounter dyslipidemia or deranged lipid and serum HDL levels. Frequency and profile therefore, a drug which not only percentage was used to express qualitative improves glycemic control but has added variables. Stratification was done to control benefits becomes important and drug of choice. effect modifiers like age, gender and BMI. This drug has a relatively safe side effect profile Comparison between groups was done therefore most of the patients tolerated the independent samples t test, difference between before and after treatment values were analysed This aspect of dyslipidemia has been using paired t test. A p value < 0.05 was studied very less in our population but is considered significant. gaining large attention in the world. The results of the study clearly show that there is statistically significant improvement in serum The age of the study population ranged HDL profile in patients treated with from 30 to 80 years. Mean age of the patients in Pioglitazone. In this study, patients in both the group A was 54.43 ± 9.66 years and mean age in groups belonged to either gender or the age group B was 53.62 ± 9.57. In group A, the mean group included 30-80 years. Statistically Serum HDL levels at presentation was 46.38 significant results were seen as improvement in ±6.45 mg/dl, in group B it was 45.93 ± 6.43 serum HDL levels of the group treated with Pioglitazone. Test of significance revealed p- characteristics of study group are described in value of<0.05(0.0001). Since most common dyslipidemia is deranged HDL levels, this drug In group A, mean serum HDL, 3 months can be more beneficial in our population. after treatment was 49.80 ± 5.86 mg/dl and the Pioglitazone is currently approved as a mean in group B was 45.73 ± 5.97 mg/dl, with third line therapy. But in patients who show significant difference(p=0.001).There were no marked lipid abnormalities this may be used significant differences of BMI, BSF, Hba1c levels earli Also for those patients in which HDL between group A and group B.
