Brief Summary:
This is a double blinded randomized clinical trial of pioglitazone vs. placebo in overweight or obese, diabetic and non-diabetic hemodialysis patients. This study will examine whether pioglitazone modulates adipokine production by adipose tissue in hemodialysis patients and whether these changes result in reduction of inflammation, insulin resistance and oxidative stress and increase in muscle mass.
In addition, this study will also examine the associations of adiposity with adipokines and the metabolic milieu in hemodialysis patients to better understand the biology of adipocytes in uremic milieu.

Detailed Description:
Randomization:
100 overweight or obese patients will be randomly allocated to oral pioglitazone 15 mg/d or placebo for two weeks by blocks of five using a random number generator and monitored for adverse events including hypoglycemia. If they tolerate the 15 mg pioglitazone or matching placebo for two weeks, participants will be assigned to 30 mg of pioglitazone or matching placebo for 24 more weeks. Those who received 15 mg of pioglitazone will receive 30 mg of pioglitazone for the next 24 weeks. Those who received placebo for initial 2 weeks will receive another placebo that matches the 30 mg pioglitazone pill for 24 weeks.
Baseline:
Participants will have fasting blood drawn for adipokines: Tumor Necrosis Factor-alpha (TNF-alpha), Interleukin-6 (IL-6), high sensitivity C-Reactive Protein (hsCRP), high molecular weight Adiponectin (HMW-A), and leptin. All patients will undergo MRI scans on the mid-week non-dialysis day. Twenty each of overweight/obese patients randomized to pioglitazone or placebo will also undergo subcutaneous fat biopsy on the mid-week non-dialysis day.
Study Period:
Participants will return to the dialysis unit at weeks 2, 4, 6, 10, 14, 18, 22, and 26. During these visits, clinical assessments will be conducted including review of blood sugars, jaundice, weight gain, and visual symptoms. Study treatment compliance will be assessed and details of adverse events experienced, particularly hospitalizations and emergency department visits will be collected. Fasting blood draws for primary and secondary outcomes will be collected on visit weeks 10 and 26.
