Summary

The purpose of this research study is to: Improve the effectiveness of vaccinations by identifying the effect of cholesterol medication, statins, on immune responses.

Clinical Details

Official title: The Effect of Short-term Atorvastatin Treatment on Immune Responses to Pneumovax 23

Study design: Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Health Services Research

Primary outcome: Determine the effect of atorvastatin treatment on pneumococcal antigen specific antibody production.

Secondary outcome: Determine the effect of atorvastatin treatment on immunogenic cytokine levels following pneumococcal vaccination.

Detailed description: Due to the anti-inflammatory action of statins, it was proposed that statin treatment would decrease the efficacy of vaccination. This response has yet to be explored following a primary vaccination such as pneumococcal pneumonia. In this study, healthy volunteers will be divided into 2 arms receiving treatment for 28 days: 40 mg atorvastatin or placebo. Antibody titer for 23 serotypes, complete blood count (CBC), high-sensitivity c-reactive protein (hsCRP), erythrocyte sedimentation rate (ESR), lipids, cytokines (TNF-alpha, IFN-gamma, interleukins, etc.) and key membrane receptors (toll-like receptors, etc.) will be measured for baseline before statin or placebo treatment. On day 7 of treatment, pre-vaccination measures of the above parameters will be taken and an immune response will be induced in all groups using Pneumovax 23 at Day 7. On days 8, 14, 21, and 28 post-vaccination measures will be compared to baseline and between groups.
