As a result of effective beta adrenergic blockade with either propranolol or practolol, plasma renin activity was suppressed in all of 11 patients with cirrhosis and ascites. In contrast, the effect on the rate of renal excretion of aldosterone was variable, suggesting that factors other than the renin-angiotension system are responsible for the control of aldosterone secretion in cirrhosis. The changes in aldosterone could not be explained on the basis of changes in the plasma concentrations of potassium or sodium. The renal sodium excretion was inversely related to the values for aldosterone both before and after beta adrenergic blockade, indicating a major role for aldosterone in regulating sodium excretion. A number of patients had an abnormal intrarenal distribution of plasma flow with a relative hypoperfusion of the renin-secreting outer cortical nephrons. Plasma renin activity was inversely related to outer cortical plasma flow, suggesting that the reduced outer cortical flow may be a stimulus to increased renin secretion. Because the abnormal intrarenal hemodynamic pattern was not corrected by suppression of plasma renin activity, and presumably angiotension II concentrations, it is unlikely that it is attributable to the known renal vasonconstrictor effects of angiotensin II.

Amongst 108 surgical patients receiving massive transfusions, 60 died. Study of the aetiology of the haemorrhage, the circumstances of the transfusion, and the role of massive transfusions in the transmission of infectious diseases, disturbances in haemostasis, immunological, respiratory and metabolic complications led to the determination of certain simple criteria of gravity which may restrict their use:age over 60 years; the number of units used, if it exceeds 30; the existence of cirrhosis, of an acute lesion as the source of bleeding, or of peroperative haemorrhage. By contrast, the transmission of hepatitis, coagulation disturbances, immediate or delayed incompatibility accidents and variations in pH, blood potassium and calcium levels and arterial pO2 had little influence on mortality.

Two-hundred and eighty-six liver biopsies were performed in 139 psoriatics on treatment or considered for treatment with methotrexate. In 56 psoriatics included in this study both pre- and post-methotrexate biopsies were performed, the average methotrexate dose being 936 mg. None of the data showed statistically significant differences between pre- and post-methotrexate biopsies, with the exception of an increase in fattly infiltration, found when comparing all pre-methotrexate biopsies with the total number of latest post-methotrexate samples. As expected, alcohol seemed to be significantly associated with liver fibrosis in pre-methotrexate biopsies. An patients, although potassium arsenite alone has not been proved to be the cause of liver damage among psoriatics included in this study. While only 1 of 22 psoriatics with a total normal biopsy had been on arsenite, 6 of 18 of the same group of psoriatics who had fibrosis had been on this drug earlier. Although no statistically significant differences related to fibrosis and cirrhosis could that in three cases liver cirrhosis did appear in a biopsy from a methotrexate-treated psoriatic who had signs of fibrosis of cirrhosis in a pre-methotrexate biopsy. This incidence is low in relation to the total number of patients treated. The relatively low incidence of cirrhosis found in the present study, as in earlier studies by our group is believed to be due to the use of an intermittent dosage schedule. The study showed that early fibrosis and cirrhosis seem to appear, with very minor abnormalities in laboratory results. This finding indicates the necessity of performing liver biopsies in the control of psoriatics on long-term methotrexate therapy. The difference between biopsies from psoriatics and liver biopsies from control patients may indicate that severity of disease may be a complicating factor in the pathogenesis of the liver damage.

Liver specimens from 103 patients with various hepatic diseases and from 297 consecutive liver biopsies examined routinely were stained with orcein after oxidation of the tissue sections with potassium permanganate. Orcein-positive dark brown cytoplasmic material could be demonstrated in 27 cases with long-standing cholestasis. These patients had either primary biliary cirrhosis, the cholestatic liver disease of ulcerative colitis or chronic active hepatitis, advanced alcoholic cirrhosis or secondary biliary cirrhosis due to extrahepatic biliary obstruction. Orcein-positive material could not be demonstrated in congenital disorders of bilirubin metabolism or in hemochromatosis. Similarly, it could not be found in acute, toxic, alcoholic or chronic persistent hepatitis.

Serum angiotensin I converting enzyme, identical with kininase II, was measured fluorometrically in patients with acute viral hepatitis (n=18), liver cirrhosis without (n=44) and with (n=19) ascites. In all groups of patients the enzyme was significantly elevated as compared to 44 healthy controls (p less than 0.001). No correlation could be found between angiotensin I converting enzyme activity and liver function tests (serum glutamic oxalacetic transaminase, serum glutamic pyruvic transaminase, total protein, albumin, bilirubin) or other parameters (serum potassium, serum sodium). High serum converting enzyme activity in chronic liver diseases might originate primarily from an altered pulmonary circulation and indicates higher conversion rate of angiotensin I by passage through the lungs as well as increased bradykinin degradation. The reason for the enzyme liberation in acute viral hepatitis is as yet uncertain.

In a series of 68 cirrhotics subjected to portacaval anastomosis for digestive haemorrhage, alterations in the acid base balance, 3, 6, 12, 24 and 48 weeks after anastomosis, were examined. Following operation, an increase in the incidence of the usual acid base disturbances of liver cirrhosis is observed. Respiratory alkalosis increases with no direct relationship to teh postoperative increase in ammoniemia, the main stimulating agent of the resporatory centres. This is probably because the active fraction on the nerve cells is the non-ionized one only, freely diffusible through the haematoencephalic barrier, the plasma concentration of which is a function of blood pH. Postoperative metabolic alkalosis is secondary to the potassium and chloride depletion consequent on operative trauma, on the malnutrition syndrome and, in the case of potassium, on secondary hyperaldosteronism which, unlike what is observed in the other groups of cirrhotics, is uncorrected by anastomosis. After the shunt, metabolic acidosis may be the expression of an increase in lactates and pyruvates following on further liver function deterioration, and of a functional renal insufficiency which anastomosis makes more manifest.

Eighteen patients with hepatic cirrhosis or nephrotic syndrome and having edema and/or ascites were treated during successive periods with metolazone 5 to 40 mg/day, spironolactone 100 mg/day, and with both diuretics concurrently. Metolazone alone produced a marked diuresis, natriuresis, and weight loss in 8 patients. Spironolactone alone had little effect, but the addition of metolazone renewed diuresis and natriuresis and resulted in additional substantial weight losses in all patients responsive to metolazone alone. Concurrent spironolactone and metolazone also induced moderate diuretic effects in some patients who failed to respond to either drug alone. The drugs were well tolerated; the administration of spironolactone with metolazone prevented decreases in serum potassium, which had occurred during treatment with metolazone alone.

In most regimens proposed for the depletive management of cirrhosis of the liver, spirolactone is associated with other diuretics. Treatment of 28 patients with uncompensated forms by means of spirolactone only, using high, protracted doses determined essentially in accordance with the depletion obtained, is described. The disappearance of signs of water retention was gradual and unattended by difficulties. Normalisation of the urinary Na/K ratio preceded the diuretic response; Increased diuresis led to a slight increase in urinary potassium/day. Higher doses were used in patients with lower urinary Na/K ratios. Here a critical diuretic response was only obtained around the 5th day. Transient low blood sodium and chlorine and high blood potassium were noted; the last parameter was not related to the drug dose, nor to changes in Bun; No marked changes in blood uric acid, calcium, ammonium, bilirubin or sugar were observed.

In a three-way crossover study, 23 patients with hepatic cirrhosis, ascites, and dependent edema received 40 mg/day of furosemide alone and combined with triamterene 50 mg/day and triamterine 100 mg/day. Baseline potassium excretion did not increase when furosemide was given alone, but potassium excretion fell when 50 mg or 100 mg of triamterene was also given. Both doses of triamterene augmented the natriuretic effect of furosemide.

Nineteen patients with severe oedema due to either cirrhosis of the liver or to congestive cardiac failure, who had failed to respond to previous diuretic therapy, were treated with either increasing doses of frusemide (Group A), or with frusemide in a fixed dose of 80 mg daily and increasing doses of spironolactone (Group B). In Group A there was an inverse correlation between the baseline 24-hr urinary sodium: potassium (Na : K) ratio and the 24-hr urinary potassium excretion during diuresis, and a direct correlation between the urinary Na : K ratio before and after diuresis. Thus, in patients of this group during diuresis, there was a significantly higher urinary potassium excretion in those with a baseline urinary Na : K ratio of less than 1, as compared with those with a ratio of greater than 1. In Group B a satisfactory diuresis was achieved without marked urinary potassium loss in those patients with a baseline urinary Na : K ratio of less than 1, whereas no diuresis was obtained in the two patients with a baseline urinary Na : K ratio of greater than 1. These results suggest that the measurement of the baseline urinary Na : K ratio is of help in determining the potential value of spironolactone in patients with resistant oedema.
