Most forms of liver disease are probably associated with impaired gluconeogenesis, although hypoglycaemia is rarely an important clinical feature. Blood concentrations of the gluconeogenic precursors, lactate, glycerol and alanine are elevated although, in certain situations, alanine levels may be decreased. Abnormal glucose tolerance is present in both acute and chronic liver disease, but is usually not of clinical importance. The mechanism of glucose intolerance remains uncertain, with diminished hepatocyte mass, portal diversion and insulin resistance the major postulates. Indeed, the importance of the liver in disposing of an oral glucose load, is still questioned. Both hyperinsulinism and hypoinsulinism are found in liver disease, with hyperinsulinism common in cirrhosis and acute viral hepatitis. This is accompanied by insulin resistance. The hyperinsulinism is probably due to defective hepatic clearance of insulin rather that to over-production. The cause of the insulin resistance remains to be established. Glucagon levels are raised and may contribute to this resistance. Growth hormone levels are also increased but are associated with low somatomedin levels and the role of growth hormone in insulin resistance is therefore questionable. Future developments include use of new animal models, studies of biopsy specimens and studies of hepatic hormone receptors.

The incidence of HBAg in viral hepatitis, in chronic active hepatitis and in cirrhosis has been investigated by using immunological methods and a solid-phase radioimmunoassay. RIA demonstrated as positive: 90% of 20 patients with posttransfusion hepatitis; 88% of 50 patients with acute viral hepatitis; 100% of 13 patients with chronic active hepatitis and 35% of 20 patients with cirrhosis; whereas the frequency of HBAg in the same patients appeared to be lower by AGD, CIEP and CF. The measure of antigenaemia has been obtained by use of HBAg (ad) dose response standard curve. The quantitative HBAg data of an eight-week follow-up of fully recovered 15 patients with acute hepatitis are reported. In the first week it appeared a distribution of the HBAg levels into three classes of values. The concentration of HBAg in the serum became lower week by week and in 8th week the antigen was no longer detectable. The radioimmunoquantitation of HBAg in the serum of patients suffering from chronic acitve hepatitis and cirrhosis showed wide levels of antigenaemia ranging between 17 and 5100 ng ad equivalent/ml. The use of a dose response standard curve in order to quantify HBAg in the serum represents a further increased sensitivity of RIA.

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.

Hepatic dysfunction is a common finding in patients with sickle cell disease but viral hepatitis appears to be an unusual complication in the adult SS patient. Only five cases of viral hepatitis were recorded in 378 admissions for SS crisis. In contrast, hepatic crisis occurred as a distinct event in 9% of 88 patients with sickle cell anemia. This entity must be differentiated from acute cholecystitis or viral hepatitis. Transiently abnormal results of hepatitic function tests were observed in another 26 patients with extrahepatic crisis. Cirrhosis is relatively common and often the terminal event in SS disease. Choledocholithiasis and cholecystitis are infrequent complications despite the prevalence of gallstones in SS anemia.

Transition from acute to chronic hepatitis has important prognostic and therapeutic implications. In 17 patients with acute viral hepatitis, observed during a period of 7 years, a liver biopsy showed changes compatible with chronic aggressive hepatitis and superimposed acute hepatitis. Follow-up biopsies showed normal liver in 14 cases, chronic persistent hepatitis in 1, and cirrhosis in 2. In 12 cases the initial biopsy which showed changes suggestive of chronicity was taken 1 month after onset of symptoms of acute hepatitis, or later. Cases developing chronic liver disease showed no characteristic clinical, laboratory, or histological features at the time of the first biopsy. If the diagnosis of chronic active hepatitis is based on histological findings alone in patients with prolonged acute hepatitis, the incidence of this condition will be grossly overestimated. The transition from acute to chronic hepatitis cannot be recognized with any degree of certainty by presently available methods.

Hepatic insufficiency results from extreme derangement of liver cell function. Pathophysiology and clinical picture of this syndrome are briefly discussed; the latter correlate rather poorly with laboratory data - the poorest correlation existing between clinical picture and bioptic findings. Acute hepatic insufficiency may occur in the course of every pathological process involving the liver, it does however arise most often in severe viral hepatitis with widespread disintegration of liver cells and in toxic liver damage. Chronic hepatic insufficiency is typical for the final stages of cirrhosis of the liver. Measurement of coagulation factors has proved to be the best prognostic parameter in hepatic failure.

29 348 in patients were treated from 1945-1975 on a gastroenterological ward; 1 892 (6.47%) of these patients had cirrhosis and 183 (0.63%) carcinoma of the liver. In the groups of patients who died, resp. came to autopsy percentages were considerably higher: 17% resp. 25.6% had cirrhosis, 4.9% resp. 13% had primary carcinoma of the liver. Analysis of these data shows, that the incidence of both diseases is increasing. This seems to be due in the first line to increasing alcoholism, and only to a lesser degree, at least in Middle Europe, to viral hepatitis. Taking into account other data published in Austria concerning absolute and relative incidence of primary carcinoma of the liver it can be stated, that this malignancy ranges among the 10 most frequent tumor diseases already.

The diagnosis of viral hepatitis was not confirmed in 2976 (22.79%) out of the admitted to the hospital patients for a period of 15 years. What impresses is the percentage growth for the last several years, reaching to 30. This, on one hand is associated with the greater exigence of HEI and with the strong fear of that disease as well as with the improved diagnostic possibilities of the infectious diseases wards on the other. In fact, almost all patients with icterus were admitted to infectious diseases wards, where the differential diagnosis of icterus was made. The first place among the false diagnoses is occupied by liver-bile diseases, progressing with icterus-50.81%, (cholelithiasis-29%, carcinoma-11%, cirrhosis, chronic hepatitis, steatosis, cholangiohepatitis, pancreatitis, etc-10.8%). Second, according to incidence, come the gastrointestinal diseases-13.51%, grippe and grippe-like diseases-13.44%, lung diseases-5.21%, blood-3.80%, heart-3.16%, toxic hepatitis 3.26%, etc. Thirty cases of infectious mononucleosis with icterus are reported as well as 17 patients with liver etzymopathies, syndrome of Dublin--Johnson--6 and Gilbert--Meulengracht syndrome--11. Viral hepatitis diagnosis is not always easy and in many cases it requires a complex of laboratory and other investigations and many years of experience. However, the false diagnosis could be reduced with more than a half with the careful consideration of the epidemic situation, anamnestic and clinical data.

The liver histology of 503 consecutive victims of fatal (within 24 hours) traffic accidents submitted to medico-legal autopsy are used as a standard of reference. In 370 persons (74%) no pathological changes in the liver biopsies were observed. Fatty liver was found in 120 persons (24%), non-specific portal inflammation in 7 persons, alcoholic hepatitis in 6, and portal fibrosis in 5. No cases of cirrhosis, chronic aggressive hepatitis, changes compatible with chronic persistent hepatitis, viral hepatitis, or other internationally accepted morphological diagnoses were found. A significant positive correlation between the frequency of steatosis and age groups was demonstrable. Fatty liver was found in 1% of persons below 20 years, in 18% between 20--40 years, and in 39% of persons more than 60 years in this normal material. The persons with fatty liver had a higher body weight, but the overweight was not correlated to age. It is concluded that fatty infiltration in the liver is a normal observation in aged persons.
