ABSTRACT
C1 esterase inhibitor deficiency with consequent angioedma is an uncommon condition. Nonhereditary C1 inhibitor deficiency includes underlying disorders; lymphoproliferative disorder, autoimmune disease, hypereosinophilia, drug-induced, allergic, and idiopathic forms. The as sociation of hereditary C1 esterase inhibitor deficiency with systemic lupus erythematosus has been previously described. We experienced a case with transiently decreased C1 inactivator activity and angioedema in lupus nephritis. This present case is a previously healthy 22-year-old woman, who developed intermittent facial angioedema and decreased urine amount. After steroid treatment, the C1 inactivator activity was recovered and angioedema was disappeared.
