| A rare genetic systemic or rheumatologic disease with characteristics of neonatal or infantile onset of enterocolitis (which resolves with age), periodic fever and episodes of severe systemic inflammation, which may be precipitated by infections, stress, or fatigue. Signs and symptoms include splenomegaly, urticaria-like rashes, arthralgia and myalgia. Associated laboratory findings are elevated inflammatory markers (such as ferritin, C-reactive protein), pancytopenia and elevated transaminases. If left untreated, flares can progress to coagulopathy, organ failure and death. |
