Angioedema hereditário: considerações sobre terapia

Abstract: 314CHAGAS KN ET AL. sendo mutações pontuais ou pequenas deleções ou inserções 3,4 . A maior função do C1-INH no corpo humano inclui a inibição direta da calicreína ativada, inibição do fator de Hageman (fator XII da cascata da coagulação) e prevenção da ativação do componente C1 do sistema complemento 5 . A diminuição da atividade de C1-INH permite a ativação de C1, com início da atividade, e consumo, de C4 e C2, resultando em diminuição de seus níveis séricos durante os ataques de HAE 6 . As formas de angioed… Show more

“…Church JA reported the use of 0.1 mg/kg/day in a child and virilizing effects were seen. The drug has to be formulated so decreasing concentrations could be tried (level III evidence) 86, 87.…”

“…Although it is an autosomal dominant disease, it is detected more frequently and severely in women. [1][2][3][4][5] Family history with similar clinical manifestations reinforces the HAE diagnosis. About 75-80% of HAE cases occur in the same family while 20-25% of cases are due to novel spontaneous mutations.…”

“…(2) C1-INH dysfunction due to a mutation in exon 8 of the SERPING1 gene that results in the secretion of a non-functional protein; and (3) normal C1-INH that may be associated with mutations in the F12, ANGPT1, PLG, and Kininogen 1 (KNG1) genes, mainly found in female patients with normal C1-INH protein levels and activity. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] A variant of the ANGPT1 gene was reported to interfere with the interaction between the angiopoietin protein and its natural receptor, endothelial tunica of the kinase cell-(TIE2), in endothelial cells leading to increased vascular permeability and edema. 12,15, 16 A mutation in the PLG gene has also been reported to increase fibrinolysis, which in turn causes plasmin formation and increased levels of bradykinin, leading to edema (PLG).…”

“…Nas crises agudas de AEH, o tratamento consiste na administração de concentrado purificado de C1-INH ou na falta deste, na infusão de plasma fresco congelado (Chagas et al;2004). A profilaxia com andrógenos atenuados (danazol, estanazolol e oxandrolona) é efetiva na prevenção dos sintomas quando sua freqüência e gravidade afetam a qualidade de vida.…”
