Brief Summary

Background: \- The drug rosuvastatin (also called Crestor) is used to lower cholesterol levels in people with elevated cholesterol levels. Recent studies have suggested that rosuvastatin may affect the immune system and reduce inflammation, but the reason for this effect is unclear. Researchers are interested in testing the effect of rosuvastatin on the immune systems of healthy volunteers with good cholesterol levels. Objectives: \- To evaluate the effect of rosuvastatin on the immune systems of healthy volunteers. Eligibility: \- Healthy individuals at least 18 years of age who have an acceptable blood level of LDL cholesterol (below 160). Design:

• Participants will be screened with a medical history and physical examination, as well as blood tests to check general health, cholesterol levels, liver function, and the C-reactive protein (which responds to inflammation).
• Participants will not be permitted to take most prescription and over-the-counter medications that affect the immune system, including antihistamines and certain pain relievers. For 1 week before the study, participants will have a wash-out period without any of these medications.
• Participants will take rosuvastatin daily for 4 weeks, always in the evening (to ensure consistent blood sample results).
• Participants will provide blood samples at the following time points: (1) immediately before the start of the rosuvastatin treatment, (2) after 2 weeks of treatment, (3) after 4 weeks of treatment, and (4) 2 weeks after the end of treatment.

Outcome Measures

Primary Outcomes (1)

• To elucidate the effects of a four week course of statins on the immune system in healthy volunteers with normal cholesterol with or without elevated C- reactive protein.

  An understanding of the mechanism by which statins effect the immune system may help us better define the patient population that might benefit from such therapy and potentially develop drugs that act more selectively and potently on the relevant immunologic pathway(s). We will also address the potential antithrombotic activity of statins.This study has been slow to recruit healthy subjects with elevated CRP, often because subjects with elevated CRP had mild abnormalities on a detailed history and physical exam, such as impaired fasting glucose. In addition, preliminary analysis of the cohort of normal CRP suggests a significant reduction in serum IL-17 during statin therapy. Psoriasis is an inflammatory disease that affects the skin and the joints, is assumed to be IL-17 driven17, and subjects are usually free of systemic imunosuppression.

Secondary Outcomes (1)

• To describe the effects of statins on platelet activity and coagulation during thrombus formation.

Eligibility Criteria

• Subjects with fasting glucose \< 125 mg/dL

You may not qualify if:

• Female subjects may not be pregnant or lactating due to minor side effects of use of statins in a non-benefit study.

• Other contraindication to statins (i.e. inadequately treated hypothyroidism, renal impairment, liver disease, elevated transaminases, diabetes mellitus or hypersensitivity to a statin)
• Subjects unable to comprehend the investigational nature of the procedure or unable or unwilling to sign the consent.
• Statin usage within the last six months prior to enrollment.
