Renal vasoactive hormones in scleroderma (progressive systemic sclerosis).
Plasma renin activity and the urinary excretions of kallikrein, kinin, immunoreactive PGE (iPGE) and aldosterone were determined in 23 patients with progressive systemic sclerosis (PSS) on a fixed sodium and potassium intake who had no clinically apparent renal disease. Urinary excretions of kallikrein and kinin in the PSS patients were not significantly different from those of a group of sex and race-matched normal controls. In the female PSS patients urinary excretion of iPGE was also found to be normal. Upright PRA was appropriate for the urinary sodium excretion in 18 PSS patients (13 normotensive and 5 hypertensives) but was significantly elevated in the remaining 5 (all normotensive). The data suggest that the renal kallikrein-kinin and prostaglandin systems are unaltered in PSS patients without clinical evidence of renal disease.
