The National Institutes of Health (NIH) announced a new clinical research program that will aim to provide answers to patients with mysterious conditions that have long eluded diagnosis.

Called the Undiagnosed Diseases Program, the trans-NIH initiative will focus on the most puzzling medical cases referred to the NIH Clinical Center in Bethesda, Md., by physicians across the nation.  

“A small number of patients suffer from symptoms that do not correspond to known conditions, making their care and treatment extraordinarily difficult. However, the history of biomedical research has taught us that careful study of baffling cases can provide new insights into the mechanisms of disease — both rare and common,” said NIH Director Elias A. Zerhouni, M.D., who has made a point during his six-year tenure at NIH of encouraging trans-NIH initiatives. “The goal of NIH’s Undiagnosed Diseases Program is two-pronged: to improve disease management for individual patients and to advance medical knowledge in general.”

With the program infrastructure now in place, the program is ready to accept patients, the first of which is expected to be seen in July 2008.

“The NIH Clinical Center, the nation’s clinical research hospital, provides an extraordinary environment for excellence in both patient care and collaborative clinical investigation,” said Dr. Gallin. “This new program will capitalize on a rich set of skills already at the Clinical Center to help patients with unusual medical conditions. These patients partner with us in clinical research to identify new diseases or new treatment.”

To evaluate each patient enrolled in the new program, NIH will enlist the expertise of more than 25 of its senior attending physicians, whose specialties include endocrinology, immunology, oncology, dermatology, dentistry, cardiology and genetics. Dr. Gahl, who is an expert on rare genetic diseases, will serve as director of the new program.

“We have developed a stringent referral process to ensure this program deals with those cases that have truly confounded medical experts,” Dr. Gahl said. “We will be very selective when it comes to patient eligibility. Our focus is strictly on conditions that have not been diagnosed.”

To be considered for this NIH pilot program, a patient must be referred by a physician and provide all medical records and diagnostic test results requested by NIH. Patients who meet the program’s criteria — as many as 100 each year — will then be asked to undergo additional evaluation during a visit to the NIH Clinical Center that may take up to a week.

Two nurse practitioners will manage patient recruitment and logistics for the new program, which will utilize existing facilities and staff already at the NIH Clinical Center, NHGRI and ORD. Funding for the program includes $280,000 per year from the ORD.
