    Journal: Vnitr Lek; 1995 Oct; 41(10):667-71. PubMed ID: 8578696.
    Abstract:
    The authors assessed in 40 patients with cirrhosis of the liver and in 33 controls the plasma renin activity (PRA), aldosterone (PA), the atrial natriuretic factor (ANF) and the digoxin like activity (DLA) in plasma under basal conditions. In patients with cirrhosis of the liver they found significantly lower levels of PRA, PA and DLA, as compared with the control group, the ANF levels were not significantly altered. In the group with cirrhosis the highest neuroendocrine activity was recorded, in particular of PRA and PA in decompensated cirrhotics receiving diuretic treatment. Therefore it is useful to combine diuretics with preparations or measures which reduce the activity of the renin-angiotensin-aldosterone system and/or promote the activity of natriuretic substances. The authors found a negative correlation between PRA and SNa, PRA and UNaV, while ANF did not correlate with natriuresis. The main determinant of Na excretion in decompensated cirrhosis is the activity of the renin-angiotensin-aldosterone system. DLA plasma levels also correlated inversely with SNa values and Na excretion and thus also reflect the severity of fluid retention.
