title: [Angioedema in hereditary deficiency of complement factor 1 esterase inhibitor and alpha 1-antitrypsin].
abstract: METHODS
  A 15-year-old girl had suffered from episodic, sometimes threatening angioedema of the face, nasopharyngeal space and distal extremities beginning at age 13.
  
  
  RESULTS
  A C1-esterase inhibitor (C1-INH) deficiency was revealed protein-chemically and functionally. There was also an alpha (1)-antitrypsin (AAT) deficiency with heterocygotic phenotype PiMZ. The combination of C1-INH and AAT deficiency was also found in the patient's mother and brother.
  
  
  RESULTS
  Under 8-month therapy with 200 mg/d danazol per os (reduction of the dosis in the last month to 100 mg/d), there was no further edema, the C1-INH concentration normalized and there was also an increase in C1-INH function. During the observation period, use of the emergency set with C1-INH concentrate was not required.
  
  
  CONCLUSIONS
  This is the first reported case of angioedema in combination of two hereditary enzyme defects C1-INH deficiency (autosomal-dominant genetics) and AAT deficiency (autosomal-recessive). In addition to a survey of current literature, the current state of diagnostics and therapy of the hereditary angioedema is presented.
