What is familial Mediterranean fever?
Familial Mediterranean fever is an inherited condition characterized by recurrent episodes of painful inflammation in the abdomen, chest, or joints. These episodes are often accompanied by fever and sometimes a rash. The first episode usually occurs in childhood or the teenage years, but in some cases, the initial attack occurs much later in life. Typically, episodes last 12 to 72 hours and can vary in severity. The length of time between attacks is also variable. Without treatment to help prevent attacks and complications, a buildup of certain protein deposits (amyloidosis) in the body’s organs and tissues may occur, which can lead to kidney failure.
