title: [Hereditary angioneurotic edema: an underestimated medical emergency. Apropos of 33 cases].
abstract: BACKGROUND
  Hereditary angio-oedema is a poorly understood disease. In more than 70 p. 100 of the cases, diagnosis is made 5 to 10 years after the first manifestations despite their typical nature.
  
  
  METHODS
  We examined retrospectively 33 cases of hereditary angio-neurotic oedema treated at the Besançon University Hospital from 1973 to 1990.
  
  
  RESULTS
  Laryngeal oedema was the most dangerous complication causing a critical episode in 22 cases. Ten patients were given danazol.
  
  
  CONCLUSIONS
  This study emphasizes that preventive treatment is essential, based on danazol which should be prescribed at the lowest dose which gives a 50 p. 100 rise in the C2 complement fraction (usually 50 to 200 mg/day). Life-threatening attacks should be treated with purified C1 INH, although there are still problems with drug supply.
