Last fall, the Infectious Diseases Society of America (IDSA) released updated guidelines for the diagnosis and treatment of Lyme disease. (See Drug Topics, Nov. 20, 2006, "Updated Lyme disease guide clarifies confusion".) Approximately one month later, Connecticut attorney general Richard Blumenthal issued a Civil Investigative Demand (CID) to look into possible antitrust violations by IDSA in connection with exclusionary conduct and monopolization in the development of its Lyme disease guidelines.
