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 کاملangioedema in a patient with c1 esterase inhibitor deficiency
angioedema is characterized by recurrent, circumscribed, solitary or multiple subcutaneous and mucosal swelling, involving the extremities, face, larynx, bowel wall. angioedema is due to hereditary or acquired varieties of c1 esterase inhibitor (c1inh) deficiency. a case of atypical acquired angioedema in a 49-year old man, responding favourably to cinnarizine and alcohol abstinence, is present...
متن کاملAcquired C1 esterase inhibitor deficiency or serendipity? The chance finding of a paraprotein after an apparently low C1 esterase inhibitor concentration.
Acquired C1 esterase inhibitor deficiency is a rare condition, usually presenting after the 2nd decade of life, and is often related to underlying conditions such as autoimmune and lymphoproliferative disorders. This case report describes a man whose initial clinical presentation with acute angioedema and whose initial estimation of a low C1 esterase inhibitor concentration indicated that he ha...
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 ...
متن کاملA nationwide study of acquired C1-inhibitor deficiency in France
Acquired angioedema (AAE) due to C1-inhibitor (C1INH) deficiency is rare. Treatment options for acute attacks are variable and used off-label. Successful treatment of the associated lymphoma with rituximab seems to prevent acute attacks in subjects with AAE. The aim of this study was to describe AAE manifestations, its associated diseases, and patients' responses to treatments in a representati...
