[Study of the renal tubular function in alcoholic hepatic cirrhosis (author's transl)].
The renal plasma flow (RPF), glomerular filtrate (GF), renal concentration strength and urinary acidification capacity in eight patients with alcoholic cirrhosis and five control subjects was studied. The maximum urinary acidification capacity was tested by means or arginine monochloride. In two patients, renal tubular acidosis (RTA) was observed. One patient manifested a slight decrease in RPF, GF, hyposthenuria, hyperchloremic metabolic acidosis and bicarbonaturia. The test for maintained acidification and the overload of bicarbonate indicated a mixed RTA. The other patient manifested incomplete distal RTA, which was briefly corrected with the administration of furosemide. These tubular defects were not associated with the loss of proteins, phosphates, glucose, aminoacids or renal lithiasis. Neither were they related to the serum levels of copper, globulins, or predisposition to hepatic encephalopathy. The association between hepatic cirrhosis and distal tubular acidosis is known, but until the present work, the fact that this hepatopathy can simultaneously affect the proximal and distal tubules had not been described.
