Endotoxin or lipopolysaccharide (LPS) is a small part of bacteria (that is no longer living) that can cause many of the effects similar to bacterial infections in humans. However, it can be administered in very small amounts to produce a mild immune response much the same as a 'flu' like illness. Within 1 ½ -3 hours after giving LPS by vein, a response consisting of fever, chills, headache, nausea and vomiting and generalized aches and pains will occur which lasts up to 6-8 hours. In addition to the flu like symptoms, the response causes temporary changes in cholesterol, triglycerides and blood sugar. Different people respond differently to LPS. We are using LPS in this study to bring on a temporary inflammatory response in the body and to compare the responses of people who receive Lovaza® or Tricor® to the responses of people who receive a placebo (pill that does not contain medicine).
