What is thalidomide, and how does it work (mechanism of action)?
Thalidomide is an oral medication used for treating the skin conditions of leprosy, a disease caused by a parasite, Mycobacterium leprae. The mechanism of action of thalidomide is not well understood. The immune system reaction to Mycobacterium leprae plays an important role in producaing the skin manifestations of leprosy. Scientists believe that thalidomide modifies the reaction of the immune system to Mycobacterium leprae and thereby suppresses the skin reaction. Thalidomide also is being evaluated as a treatment for HIV and several other conditions. Thalidomide was approved by the FDA in July 1998.

The recommended adult dose is 100-400 mg daily for treatment of leprosy. The dose for treating multiple myeloma is 200 mg daily in combination with dexamethasone. Thalidomide should be administered in the evening at least one hour after meals and with a full glass of water.

Thalidomide increases the sedative effect of alcohol and other drugs that cause drowsiness (for example, diazepam [Valium]). Drugs that slow heart rate add to the heart slowing effects of thalidomide. Examples of such drugs include calcium channel blockers (CCBs), beta blockers, and digoxin (Lanoxin). The incidence of peripheral neuropathy increases when thalidomide is combined with other drugs (for example, amiodarone [Cordarone], cisplatin, phenytoin [Dilantin, Dilantin-125]) that also cause peripheral neuropathy.

Castleman Disease
Castleman disease is a group of related conditions. It is a rare disease with an unknown prevalence. Castleman disease is caused by an abnormal growth of lymphocytes, a type of white blood cell. There are two types of Castleman disease; 1) unicentric, and 2) multicentric. Castleman disease is diagnosed by biopsy of the suspected lymph nodes. Castleman disease is treated with medications (for example, corticosteroids, chemotherapy drugs, immunodilating drugs, interferon-alfa, and antiviral medications), surgery, and radiation therapy. The life expectancy for a person with Castleman disease is difficult to determine because the condition is rare and takes different forms.
