Purpose

The purpose of the study is to establish the safety of Zocor and Vytorin in adolescents with Type 1 Diabetes and to determine the amount of decrease in LDL-cholesterol.The study hypothesizes that Zocor and Vytorin will be safe in adolescents with Type 1 Diabetes and will lower LDL-cholesterol at 6 months.

Primary Outcome Measures:

LDL-c levels between Zocor and Vytorin treatment in subjects with Type 1 Diabetes. [ Time Frame: one year ]

Secondary Outcome Measures:

HgbA1c, lipid panel, vertical auto profile (VAP), creatinine kinase, Liver function tests, thyroid function, CRP, arterial stiffness measurements, insulin dose, diabetes duration, continuous glucose measurement, and blood pressure. [ Time Frame: one year ]

Estimated Enrollment:	82
Study Start Date:	May 2007
Estimated Study Completion Date:	October 2008

Detailed Description:

Cardiovascular disease is the leading cause of death in people with type 1 diabetes mellitus (T1DM) and since atherosclerosis begins in childhood, data to inform clinicians as to appropriate dyslipidemia treatment in this high-risk population are of great public health importance. In this trial of lipid-lowering medications (Zocor [simvastatin], a statin, compared to Vytorin [ezetimibe/simvastatin], a combination of a statin and Zetia, a medication that blocks cholesterol absorption) will be performed in patients ages 12-18 years with LDL ≥ 130 mg/dl, consistent with current ADA guidelines. The study hypothesizes that Zocor and Vytorin will be safe in adolescents with T1DM and will lower LDL-cholesterol at 6 months compared to baseline. In a two-arm design, Vytorin will lower LDL-c more than monotherapy with Zocor.
