Brief Summary

HMG CoA reductase inhibitors (statins) are commonly used to treat high cholesterol (HC) in both type 1 and type 2 diabetes mellitus (DM). Several studies have shown benefits of statin among patients of type 2 DM, however, no such data is available for patients with type 1 DM. It is known from studies on cholesterol metabolism using surrogate markers that patients with type 1 DM have higher cholesterol absorption compared to normals and those with type 2 DM have higher cholesterol synthesis. Since statins inhibit synthesis, patients with type 1 DM may not have a good response and may respond better to cholesterol absorption inhibitors. The purpose of this study is to determine the cholesterol lowering effects of cholesterol absorption inhibitors and cholesterol synthesis inhibitors in subjects with type 1 and type 2 diabetes mellitus.

Outcome Measures

Primary Outcomes (1)

  • Changes in LDL Cholesterol

    Subjects with T1DM or T2DM were assigned to alternating therapy with simvastatin (40 mg) or ezetimibe (10 mg) for 6 weeks in a crossover design. The data are reported as follows. Subjects with type 1 diabetes mellitus: Simvastatin: Changes in LDL after 6-week therapy with simvastatin (irrespective of the treatment order) Ezetimibe: Changes in LDL after 6-week therapy with ezetimibe (irrespective of the treatment order) Subjects with type 2 diabetes mellitus: Simvastatin: Changes in LDL after 6-week therapy with simvastatin (irrespective of the treatment order) Ezetimibe: Changes in LDL after 6-week therapy with ezetimibe (irrespective of the treatment order)

    6 weeks after starting drug therapy

Secondary Outcomes (1)

  • Changes in Cholesterol Absorption or Synthesis Rates From the Baseline

    6 weeks after initiation of drug therapy

Study Arms (4)

Subjects with type 1 diabetes mellitus, option 1

OTHER

Half the subjects will start with arm (i.e. every other subject in order) * Simvastatin 40 mg tablet by month daily for 6 weeks, * 4 weeks washout period Half the subjects will start with arm (i.e. every other subject in order) * Ezetimibe 10 mg by month for 6 weeks * 4 weeks washout period * Simvastatin 40 mg tablet by month daily for 6 weeks

Drug: simvastatin or ezetimibe

Subjects with type 2 diabetes mellitus option 1

OTHER

Half the subjects will start with arm (i.e. every other subject in order) * Simvastatin 40 mg tablet by month daily for 6 weeks, * 4 weeks washout period Half the subjects will start with arm (i.e. every other subject in order) * Ezetimibe 10 mg by month for 6 weeks * 4 weeks washout period * Simvastatin 40 mg tablet by month daily for 6 weeks

Drug: simvastatin or ezetimibe

Subjects with type 1 diabetes mellitus, option 2

OTHER

Half the subjects will start with arm (i.e. every other subject in order) * Ezetimibe 10 mg by month for 6 weeks, * 4 weeks washout period

Drug: simvastatin or ezetimibe

Subjects with type 2 diabetes mellitus option 2

OTHER

Half the subjects will start with arm (i.e. every other subject in order) Ezetimibe 10 mg by month for 6 weeks, •4 weeks washout period

Drug: simvastatin or ezetimibe

Interventions

Subjects will be started on either simvastatin or ezetimibe (we will alternate the subjects so that half the sample will initially be treated with simvastatin and half will be started on ezetimibe). The dose of Simvastatin (Merck) is 40 mg orally at nighttime for 6 weeks and the dose of ezetimibe (Schering-Plough) is 10 mg taken orally once a day. Subjects will be instructed on low-fat diet (therapeutic life style changes diet) recommended by American Heart Association by the bionutritionist.

Limitations and Caveats

1. Smaller than desirable sample size due to difficulty in recruitment. 2. Could not evaluate the effect of duration of the diabetes mellitus as independent confirmation of the duration could not be done. 3. Apolipoprotein levels were not measured.
