Angiotensin Converting Enzyme Genotype

1. The dermal wheal response to bradykinin is increased by drugs which inhibit angiotensin-converting enzyme, and thus provides a measure of angiotensin-converting enzyme activity at the tissue level. An insertion/deletion polymorphism of the angiotensin-converting enzyme gene predicts serum angiotensin-converting enzyme activity, but its relation to angiotensin-converting enzyme activity in tissue is unclear. 2. The relations between angiotensin-converting enzyme genotype and wheal responses to intradermal bradykinin were studied in 105 healthy subjects: 30 of genotype DD, 51 of genotype ID and 24 of genotype II. Dermal wheal area was measured by digitized planimetry and the angiotensin-converting enzyme genotype by polymerase chain reaction. 3. Bradykinin produced significant linear log dose—wheal area responses. The potency of bradykinin by parallel line bioassay did not differ significantly between the genotypes; the potency in the II subjects relative to DD subjects was 1.25 (95% confidence interval: 0.83–1.88). 4. Although the angiotensin-converting enzyme gene polymorphism is a consistent and powerful predictor of serum angiotensin-converting enzyme activity, it does not appear to predict tissue angiotensin-converting enzyme activity as measured by dermal responses to bradykinin.

Angiotensin Converting Enzyme Genotype

1. Increased urinary albumin excretion is common in patients with essential hypertension and is at least to some extent correlated with prevailing blood pressure levels. However, the generalized vascular dysfunction present in advanced atherosclerotic disease may independently influence this parameter. 2. To evaluate this possibility, we assessed blood pressure, ultrasonographic carotid thickness, cardiac mass, minimum forearm vascular resistances, metabolic parameters and the angiotensin-converting enzyme genotype in patients with untreated essential hypertension and atherosclerotic peripheral vascular disease (n = 11). The results were compared with similar data obtained in matched groups of patients with uncomplicated hypertension and with normotensive control subjects (n = 11 per group). 3. Urinary albumin excretion was higher in hypertensive patients with atherosclerosis than in those without complications; carotid thickness was higher in atherosclerotic patients and a positive, statistically significant correlation existed between this parameter and urinary albumin excretion. In the same patient group, systolic blood pressure, fasting insulin and triacylglycerol levels were elevated and correlated with urinary albumin levels. However, differences in urinary albumin excretion persisted after taking into account the influence of those parameters by analysis of covariance. The distribution of angiotensin-converting enzyme genotype patterns and values of cardiac mass and minimum forearm vascular resistances did not differ significantly among the experimental groups. 4. The data suggest that vascular status may influence urinary albumin excretion in patients with essential hypertension, while confirming the importance of systolic blood pressure levels as a determinant of the raised urinary albumin excretion.
