More than 1700 estimations of serum angiotensin converting enzyme (SACE) were undertaken, mostly in respiratory disorders, to assess its value as a specific and/or a sensitive indicator of different diseases. Though highest levels were found in lepromatous leprosy consistently, it was also found almost always elevated in active stages of sarcoidosis. Since it is raised in a variety of respiratory disorders, it is not a specific diagnostic test. It is, however, a fairly sensitive index of disease activity in sarcoidosis whether on treatment or not. Sudden elevation, after a prolonged period of low or normal values may indicate relapse in sarcoidosis.

We report here a familial clustering of elevated serum angiotensin converting enzyme (ACE) levels. The patient is a 58-year-old Japanese female who had been in excellent health until age 45 when she developed an occlusion of the left central retinal vein. She was otherwise in excellent health, and no laboratory abnormality except a marked elevation of serum ACE level (625 nmol/min/ml; normal range; 22-40 nmol/min/ml of serum) was found. Her blood pressure was within normal limits (140/80 mmHg). There was no evidence for the diagnosis of sarcoidosis, Gaucher's disease, leprosy, hyperthyroidism, diabetic retinopathy, or liver disease. One of her two sisters also showed a marked increase in serum ACE activity (303 nmol/min/ml), and remarkably high levels of serum ACE (276 and 294 nmol/min/ml) were demonstrated in both sons of this sister. All the members of this family have been in excellent health. The serum ACE activity was activated by chloride and cobalt ions, and inhibited by EDTA, captopril and rabbit antiserum to purified human plasma ACE. Thus our study showed a familial clustering of elevated serum ACE in individuals who did not have conventional disease patterns associated with elevated serum ACE.

Serum angiotensin-converting enzyme activity was measured in 91 adult healthy and lepromatous armadillos before inoculation with M. leprae and at necropsises. Mean ACE values were significantly elevated in armadillos with leprosy and the degree of elevation was roughly proportional to the extent of infection. There was also significant difference in the serum ACE levels between Florida and Louisiana armadillos. The dapsone treatment resulted in bringing these levels to normal. Serial assays of serum, ACE provided information on the response of armadillos to dapsone therapy.

We report here a familial clustering of elevated serum angiotensin converting enzyme (ACE) levels. The patient was a 58-year-old Japanese female. She had been in excellent health until the age of 45, when she noticed a decrease in visual acuity of her left eye. Despite intensive therapy under the diagnosis of occulusion of the central retinal vein, she lost her visual acuity at the age of 45. Thereafter, she has been in excellent health. The only abnormality found in this case has been a markedly elevated level of serum ACE (625 n mol/min/ml; normal range; 22-40 n mol/min/ml of serum). Her blood pressure was within normal limits (140/80 mmHg). There was no evidence for the diagnosis of sarcoidosis, Gaucher's disease, leprosy, hyperthyroidism, diabetic retinopathy, or liver disease. One of her two sisters also showed a marked increase in serum ACE activity (303 n mol/min/ml), and remarkably high levels of serum ACE (276 and 294 n mol/min/ml) were demonstrated in both of two sons of this sister. All the members of this family have been in excellent health. The serum ACE activity was activated by chloride and cobalt ions, and inhibited by EDTA, captopril and rabbit antiserum to purified human plasma ACE. Thus, our study showed a familial clustering of "hyper-ACE-emia", and the disorder appears to have been inherited as an autosomal dominant trait.
