Effect of Androgel on Type 2 Diabetic Males With Hypogonadism

University at Buffalo49 enrolled

Overview

This is to study the effect of replacing testosterone on different inflammatory cells in type 2 diabetics with low testosterone levels.

Type 2 diabetes is an atherosclerotic, pro-inflammatory and pro-oxidative stress. Hypogonadism( low testosterone) is also associated with increased levels of inflammatory mediators and atherosclerosis. This project is about studying the effect of testosterone replacement on different inflammatory cells in blood and urine. It will also compare the dose dependent effect on inflammatory cells. This also involves comparing level of inflammation in hypogonadic diabetic males treated with testosterone with those not treated with any replacement therapy. This study involves applying AndroGel for 8 wks and studying effects during this time and thereafter.

Outcomes

Primary Outcomes

Effect of Androgel Treatment on Relative Nuclear Factor kB Activity Compared to Placebo

To measure the percent change from baseline at 8 weeks in Nuclear Factor kB DNA binding activity (in arbitrary units normalized to 100% at baseline) between AndroGel and Placebo using electrophoretic mobility shift assay (EMSA). Values at 8 weeks are converted to percent change and compared between the groups

Time frame: 8 weeks

Secondary Outcomes

Effect of Androgel Treatment on Reactive Oxygen Species Generation Compared to Placebo

Comparison of relative percent change from baseline at 8 weeks in reactive oxygen species generation (measured as arbitrary units normalized to 100% at baseline) in mononuclear cells after either AndroGel or placebo using chemiluminescence PMSF activation assay. Values at 8 weeks are converted to percentage of the baseline and compared between the groups

Time frame: 8 weeks

Change in Inflammatory Mediator C-Reactive Protein (CRP) Following Treatment With Testosterone

To measure the relative percent change from baseline in the inflammatory mediator (CRP) at 8 weeks (values in ng/ml normalized to100% at baseline) following treatment with androgel compared to placebo. Values (in ng/ml) are converted to percentage of baseline at 8 weeks.

Time frame: 8 week
