Summary

Lyme disease is the most common tick-borne disease in the United States. It is caused by the spirochete Borrelia burgdorferi. It may exist in a chronic form and be the result of: 1) persistent infection by B. burgdorferi; 2) damage caused by the original infectious process; or 3) the presence of coinfection with another organism transmitted by Ixodes ticks. The purpose of this study is to determine the safety and effectiveness, in seronegative patients, of intensive antibiotic treatment in eliminating symptoms of Chronic Lyme Disease (CLD).

Detailed description

Sixty-six patients will be enrolled in this study. Each patient will be assigned to one of two groups and will be randomly selected to receive either antibiotic therapy or placebo; but, the assignment of medication will not be made known to the patient or administering doctor. Antibiotic or placebo will be given intravenously (IV) for 30 consecutive days and then orally for the next 60 consecutive days.
