  • Title: The renin-angiotensin-aldosterone system in fulminant hepatic failure.
    Author: Bernardi M, Wilkinson SP, Wernze H, Spech HJ, Müller G, Poston L, Williams R.

    Abstract:
    The relationship of the renin-angiotensin-aldosterone system to blood pressure and sodium homeostasis and to renal function was investigated serially in 12 patients with fulminant hepatic failure. The plasma concentrations of renin, angiotensin II, and aldosterone were, in most instances, markedly increased. Systolic blood pressure, which was often very low, showed a significant inverse relationship to the plasma renin concentration, suggesting that the marked stimulation of the system is a homeostatic response to hypotension. However, the plasma renin substrate concentration was markedly decreased, and the conversion of angiotensin II to inactive peptides increased, both of which may have severely limited the full 'expression' of the stimulated system. Renin and angiotensin II levels were both related to creatinine clearance, which was often reduced, but it is not clear as to which was cause and which effect. No relationship between the plasma aldosterone concentration and renal sodium excretion could be detected.
