Clinical and Basic Investigations Into Erdheim Chester Disease
- Erdheim Chester Disease (ECD) is a very rare disease in which abnormal white blood cells start growing and affect the bones, kidneys, skin, and brain. ECD can cause severe lung disease, kidney failure, heart disease, and other complications that lead to death. Because ECD is a rare disease, found mostly in men over 40 years of age, there is no standard treatment for it. More information is needed to find out what genes can cause ECD and how best to treat it.
- To collect study samples and medical information on people with Erdheim Chester Disease.
- Individuals 2 to 80 year of age who have been diagnosed with Erdheim Chester Disease.
- Participants will be screened with a physical exam and medical history.
- Participants will have a study visit to provide samples for study, including blood, urine, and skin tissue samples. Participants will also have lung, heart, and muscle function tests; imaging studies of the brain, chest, and whole body; a treadmill running stress test; an eye exam; and other tests as needed by the study doctors.
- Participants will be asked to return for a similar set of tests every 2 years, and to remain in contact for possible treatment options.

|Official Title:||Clinical and Basic Investigations Into Erdheim-Chester Disease|
|Study Start Date:||July 2011|
Erdheim-Chester Diseases (ECD) is a very rare non-Langerhans cell histiocytosis of unknown origin and pathogenesis. It has been reported mainly in adult males over the age of 40 years, although cases have been reported in females as well. Children are rarely affected by this condition. No causative gene has been identified; family studies have not been performed due to the rarity and sporadic nature of the disease. The clinical characteristics of ECD range from asymptomatic to multisystemic involvement; longitudinal progression and natural history have not been well documented. ECD commonly affects the bones, kidneys, retroperitoneal space, skin and brain. After diagnosis, the disease progresses rapidly, causing fatal outcomes due to severe lung disease, chronic renal failure, cardiomyopathy and other complications. The diagnosis of ECD relies upon imaging studies and specific pathologic findings in biopsies of affected organs, i.e., fibrosis and infiltration of the affected tissues with foamy histiocytes, lymphocytes, and plasma cells. Immunohistochemistry reveals cells positive for CD68 and negative for CD1a and S-100. There is no standard treatment for ECD, although chemotherapy, radiation, stem cell transplantion, alpha-interferon, steroids and sirolimus have been proposed. Symptomatic improvement has been reported with some of these therapies, but death within a few years after diagnosis remains the expected outcome. In this protocol, we will clinically evaluate ECD patients, obtain cells, plasma, and urine, search for genes that can be responsible for ECD, and perform other studies dictated by each patient's presentation.
