title: [Angiotensin converting enzyme (ACE) in the follow-up control of children and adolescents with allergic alveolitis].
abstract: We studied the concentration of angiotensin-converting enzyme (ACE) in 80 respiratory and hepatologic healthy patients aged 4 months to 35 years. The normal values ranged from 9.4-38.8 U/ml with a tendency of lower ACE-concentrations in the older patients. In the follow up of 16 patients with hypersensitivity pneumonitis a decrease of initially elevated values of ACE was observed in 12 cases. In two patients with a recurrent course of hypersensitivity pneumonitis ACE rose to levels above 30 U/ml. These findings suggest that ACE-concentration in serum is an additional parameter to evaluate the acute stage of disease in patients with hypersensitivity pneumonitis.
