In 305 patients examined by liver biopsy albumin and the entire soluble protein in the liver puncture as well as albumin in the serum were estimated quantitatively. A significant decrease of the serum albumin level in active cirrhoses and biliary liver damages confirmed the importance of the hypalbuminaemia as facultative symptom of a liver damage. The lacking specifity was emphasized by the low albumin serum concentrations in malignomas and after the intake of contraceptive hormones. The hypalbuminaemia and the increased content of soluble liver protein in the bioptic material might enrich the diagnostics of the activity in cirrhoses. The diagnostic value of the decrease of the relative proportion of albumin is low, since of all liver diseases examined the active cirrhosis alone was accompanied by a significant decrease. The estimation of the albumin content in the bioptically got liver tissue had in contrast to the animal experiment no diagnostic value for liver diseases.

Chronic alcoholics who had been drinking heavily until admission for withdrawal from alcohol were studied to determine their level of granulocyte function, immunoglobulin concentration, and complement system activity. Although most had some mild derangement in results of liver function tests, serum albumin concentrations were normal, and there was no clinical evidence of malnutrition or cirrhosis. Granulocyte adherence was slightly depressed in two subjects (52.4% and 54.1%; normal, 76.0% +/- 12%), although mean adherence for the group was normal. Mean chemotaxis was significantly below normal (2,103 vs. 7,943 counts per min), and the impairment was related to a defect or inhibitor in the serum of patients. Phagocytic activity was less than half that of control subjects in two alcoholics, but mean values were not depressed. Bactericidal activity was normal in all. Serum concentrations of immunoglobulins and total hemolytic complement activity were above the normal range for the group. The general inhibition of chemotaxis or the occasional defects in other granulocyte functions may contribute to the difficulty that alcoholics have with infection.

Furosemide is frequently used for ascites and causes adverse reactions (AR). In an intensive prospective drug monitoring study of 1,920 patients, 172 (8.9%) had cirrhosis of the liver and received furosemide. Mean age was 53 years, and 66.3% were male; and 87% had alcoholic cirrhosis. Eighty-eight (51.2%) had 221 events that by consensus of the monitoring team and attending physicians were either definitely of probably related to furosemide. No AR was fatal but 24% of patients had severe reactions. Almost all reactions were dose-related (96%). The most common were electrolyte disturbances (23.3% of patients) and volume depletion (14%). Furosemide-induced coma occurred in 20 (11.6%) patients and was more frequent in patients with prior hepatic encephalopathy (p less than 0.0005). Higher total doses (p less than 0.001), hyerbilirubinemia (p less than 0.05), prolonged prothrombin time (p less than 0.02), and longer hospital stay (p less than 0.001) were associated with higher frequencies of AR to furosemide. The frequency of hypokalemia did not decrease when potassium chloride or potassium-sparing diuretics were added to furosemide therapy. Frequdncy of AR did not correlate with age, sex, renal impairment, serum albumin, transaminase, or alkaline phosphatase.

Derangements in glucose, amino acid and protein metabolism in patients with liver cirrhosis were examined with special reference to plasma levels of human growth hormone (HGH). Changes in blood glucose, IRI (immunoreactive insulin), HGH, FFA (free fatty acid) and plasma free amino acid levels were determined in controls and patients following either oral glucose load, protein feeding or intravenous arginine infusion. 1) In patients with liver cirrhosis, incidence of glucose intolerance after glucose tolerance test (GTT) was high and IRI levels were elevated in the fasting state as well as after glucose, protein or arginine loads. 2) Fasting levels of blood HGH were significantly higher in liver cirrhosis than in controls. GTT revealed that blood HGH levels decreased slightly during the rising phase of blood glucose, and conversely, increased during the falling phase of glucose (180 minutes after the glucose load) both in controls and in patients. In cirrhotic patients, marked increases in HGH levels were observed both 120 minutes after the protein load and 60 minutes after the arginine infusion. 3) Fasting levels of serum FFA were significantly higher in liver cirrhosis than in controls. Both controls and patients, however, showed a similar pattern of change in FFA levels following GTT or protein ingestion, i.e. a minimum value 120 minutes after the load and a gradual increase thereafter. 4) Fasting levels of plasma free amino acids were significantly higher in cirrhotic patients than in controls. After the glucose load, however, slight decrease was noted in some amino acid levels. All the amino acid levels examined were elevated following protein ingestion, particularly in cirrhotic patients. 5) A positive correlation was demonstrated in cirrhotic patients between total plasma free amino acids and maximal HGH responses following protein ingestion. Similar significant correlations were observed between the maximal HGH response and the plasma level of several amino acids such as His., Ser., Gly., Thr., Ala., and Ileu., respectively. 6) In cirrhotic patients, negative correlations were demonstrated between fasting levels of serum albumin and total plasma free amino acids or maximal HGH responses, respectively, after the protein ingestion. From these results it was inferred that derangements in the metabolism of protein and amino acids in cirrhotic patients may result in an increase in plasma free amino acid level which in turn stimulates HGH secretion. It was surmised that the HGH levels so elevated in the patients may cause FFA mobilization which in effect results in the glucose intolerance.

Amino acid imbalance ratio was determined in apparently healthy Pakistanis and patients with hepatitis and cirrhosis of the liver. The ratio was normal in 75% of the patients with actue viral hepatitis but in only 5% with cirrhosis of the liver. The ratio was abnormal in 25% cases of acute viral hepatitis possibly due to aminoaciduria. The abnormal ratio in cirrhosis of the liver indicated the functional capacity for albumin synthesis and correlated well with serum albumin concentration.

To determine the role of liver dysfunction in theophylline toxicity, we administered single intravenous doses of the drug to nine patients with cirrhosis and observed its disposition over a period of 24 to 48 hours. As compared to 19 normal subjects, these patients had a prolonged plasma half-life (mean, 25.6 vs. 6.7 hours) and a decreased plasma clearance (mean, 0.042 vs. 0.062 liter[kg-1]hr-1). Volumes of distribution of theophylline in the cirrhotic patients (central-compartment volume of 0.330, and steady-state volume of distribution of 0.785 liter per kilogram) did not substantially differ from normal (0.246 and 0.508 respectively). Plasma theophylline binding in three patients with cirrhosis averaged 36.8 per cent as compared to 52.6 per cent in four normal subjects. There was no correlation between any laboratory test of liver function and the plasma theophylline half-life, except for serum albumin (r = 0.92, P less than 0.001). The variable capacity to eliminate theophylline precludes the use of usual maintenance dose schedules for bronchodilation in cirrhosis.

12 g of albumin are synthesized daily by the bound polyribosomes of all human liver cells together, corresponding to 10% of the intravascular albumin mass. The cell is producing a precursor albumin. During secretion albumin is liberated by splitting of a small peptide. Only 40% of the total body albumin is located intravascularly. 12g of albumin are degraded or excreted daily, 30% of it by the liver, the kidneys and the gastrointestinal tract. The main site of albumin catabolism is unknown. Albumin with a half-life of about 20 days is degraded at a constant fractional catabolic rate. The absolute rate of degradation varies depending on the plasma content. This mechanism allows an effective regulation of the serum albumin level. The fractional catabolic rate, however, is not completely fixed. It is slowly reduced if the serum albumin content is markedly reduced as in protein deficiency, the blind loop syndrome, cirrhosis, nephrosis, and diseases of the gastrointestinal tract. Infusion of albumin increases the fractional catabolic rate slowly. This must be taken in consideration substitution albumin in chronic diseases. The shift from the extravascular to the intravascular compartment is a short-term regulatory mechanism. The regulation of synthesis and degradation are independent from each other. The molecular mechanism of regulation of synthesis and degradation are unknown, partially due to inadequate methods.

Serial measurements of complement components were performed in fifty-nine patients with acute, uncomplicated hepatitis and twelve with alcoholic cirrhosis. Thirty-one of the former group had detectable hepatitis B antigen. Abnormal complement profiles were observed in nine patients with hepatitis B and seven with antigen-negative hepatitis. Low levels of C4, C3 and factor B were common in the subjects with cirrhosis and confined to those cases with severe reduction in serum albumin and/or prothrombin index. By contrast, the complement changes in the patients with hepatitis occurred without significant alteration in these parameters; certain subjects also had reduction in C1q and C5 and a significant number had C3d detectable in fresh plasma. The pattern of abnormality suggests predominant involvement of the classical pathway and it is concluded that this results, at least in part, from an immune process evident only in the early clinical phase of hepatitis. Such gross changes in complement are likely to reflect immune-complex activity and it is proposed that these complexes may be important in the clearance of virus material. The data supports a previous suggestion that recovery from acute hepatitis is primarily dependent on host immune competence rather than viral cytotoxicity or generation of immune complexes.

Circulating alpha-1 acid glycoprotein level in cirrhotic patients was determined by radioimmunoassay, and was compared to the ones in normal subjects and chronic active hepatitis with sublobular necrosis. Serum alpha-1 acid glycoprotein levels in liver cirrhosis (p less than 0.001) and chronic active hepatitis with sublobular necrosis (p less than 0.02) were significantly reduced comparing to the normal subjects, although any statistically significant difference was not observed between the formers. In liver cirrhosis, thie serum alpha-1 acid glycoprotein level correlated negatively with serum albumin concentration but neither with serum alpha-1 globulin fraction nor with Indocyanine green clearance rate.
