CLINICAL REVIEW Acquired C1 Esterase Inhibitor Deficiency
Acquired C1 esterase inhibitor deficiency is a rare condition associated with autoimmune or low-grade lymphoproliferative disorders. Adults or elderly patients are most commonly affected. The diagnosis is suspected when patients present with recurrent angioedema and low serum levels of C4 with normal levels of C3. Low levels of C1q and low C1 esterase inhibitor activity confirm the diagnosis. I...
متن کاملLymphoproliferative disease and acquired C1 inhibitor deficiency.
Angioedema due to acquired deficiency of the C1-inhibitor is a bridging condition between autoimmunity and lymphoproliferation. We report 32 patients with acquired C1 inhibitor deficiency: 23 have anti C1-inhibitor autoantibodies; 13 have monoclonal gammopathies of unknown significance and 9 have non-Hodgkin's lymphoma. Our series suggest that different forms of B cell disorders coexist and/or ...

It can involve the skin, upper respiratory airways and abdomen. There are two main types: hereditary and acquired. Angioedema can involve practically any part of the cutaneous surface, it can cause lethal laryngeal edema and can present as gastrointestinal ...
متن کاملAutoantibody facilitated cleavage of C1-inhibitor in autoimmune angioedema.
C1-inhibitor (C1-Inh) is an important inhibitor of the inflammatory response and deficiency of this inhibitor, which may be hereditary or acquired, is associated with recurrent episodes of edema. Recently, an autoimmune form of angioedema has been described that is associated with functional deficiency of C1-Inh and an autoantibody that impedes C1-Inh function. In this report we describe the is...
