Angiotension converting enzyme in sarcoidosis activity

S Harrabi, A Revol, N Biot, M Perrin-Fayolle
The authors studied the parameters of Friedland and Silverstein's technique for measuring the activity of the angiotensin I conversion enzyme and found a number of anomalies. The technique was modified by correcting the wide pH difference between the pH of the reagent and the pH of the reference solution. This modification made the technique optimal for the measurement of the enzyme activity by allowing a 20 to 40 per cent increase in this activity and a 15% increase in the positivity in cases of clinical sarcoidosis...

The polypeptidyc system was studied and serum concentrations of ACE (Angiotension Converting Enzyme) were assayed in patients with Crohn's disease in the active and stabilising phases. The study was undertaken on the assumption that as a granulomatous condition Crohn's disease involves the polypeptidyc system in much the same way as in sarcoidosis. The results confirm the hypothesis revealing a significant increase in ACE levels in patients with the active disease, whereas levels in the stabilized disease were lower than in the controls...

The value of BAL in three groups of diseases (sarcoidosis, lung fibrosis, inflammatory diseases of the bronchi) compared with a control group is described. The cellular components and total protein and glycoprotein as well as electrolyts and angiotension-converting enzyme were examined. In patients with sarcoidosis a higher retention of sodium ions was stated. ACE in BAL was without any hint to the activity of the disease. But for glycoproteins a higher permeability was proved. In several fractions of the BAL fluid were differences according to all examined parameters...
