A survey of all patients in whom liver biopsy showed epithelioid granulomas was undertaken at two major teaching hospitals in Glasgow for the period 1970-1979. Seventy-seven patients with hepatic granulomas were studied retrospectively. In 53 cases (69 per cent) a clear-cut clinical diagnosis was established, which included sarcoidosis (eight cases), tuberculosis (eight), extrahepatic biliary obstruction (seven), primary liver diseases (11), neoplasm (six), bacterial infection (five) and miscellaneous (eight). In 24 patients (31 percent) no cause was found. Seventeen patients from this idiopathic group were studied prospectively and single examples of the following conditions were subsequently diagnosed; pulmonary tuberculosis, primary biliary cirrhosis, ulcerative colitis, adenocarcinoma of rectum, primary hepatocellular carcinoma, alpha-one antitrypsin deficiency and pulmonary fibrosis, sarcoidosis, pulmonary fibrosis alone, gallstones, rheumatic heart disease, unexplained hepatosplenomegaly and one death from mesenteric artery thrombosis. Only six cases remained truly idiopathic. Three of these patients recovered and in two liver biopsy became normal. The other three have persistent granulomas associated with continuing illness.

A group of 48 patients (42 suffering from hepato-biliary diseases and 6 without hepatic diseases) was followed by the authors for a period lasting from 5 to 8 years, 13 out of them for longer. The hepatic disease was assessed on the basis of physical examination, current liver chemistry and proper and specific instrumental procedures. Initial and final diagnosis and the aminotransferases (AST, ALT) trend in years were carefully considered. First of all it was concluded that no advantage is obtained in monitoring the two aminotransferases instead of one alone. Moreover it is stressed the opportunity of referring aminotransferases activities in a simple way such as per cent of variation as referred to considered upper normal value differing from one to the other laboratory. The aminotransferase increase maintains an important and diagnostic significance in acute liver damage such as in acute hepatitis. An inappreciable prognostic value may be drawn from the follow up of these enzymatic parameters: for example the development of posthepatic fibrosis, or cirrhosis or hepatoma cannot be foreseen on the basis of the aminotransferases trend. A greater variability and sharp increases in AST-ALT values are recorded in patients with biliary gallstones.

The clinical significance of the measurement of c-erbB-2 oncogene product was evaluated. The subjects consisted of 404 patients, including 248 with cancer of the digestive organs and 128 with benign digestive diseases. Serum c-erbB-2 protein levels were measured by sandwich immunoenzyme assay. The positive rates of c-erbB-2 protein, at a cut-off value of 17.0 U/ml, were, for cancers: hepatocellular carcinoma 61.6%, biliary tract cancer 54.8%, pancreatic cancer 25.0%, esophageal cancer 33.3%, gastric cancer 16.9%, and colorectal cancer 5.0%. For benign digestive diseases, the rates were: liver cirrhosis 63.3%, chronic hepatitis 43.2%, acute hepatitis 42.9%, other liver diseases 42.8%, cholelithiasis 30.0%, and chronic pancreatitis 0%. Serum c-erbB-2 protein levels were significantly correlated with the markers of hepatic functional reserve, the indocyanine green retention rate and the hepaplastin test. These findings suggest that serum c-erbB-2 protein levels are greatly influenced by liver dysfunction and that their clinical usefulness as a serum tumor marker is questionable.

Dr. Wagner's description of an advanced macronodular cirrhosis is compatible with end-stage liver disease due to a variety of causes. An alcoholic etiology seems more probable than chronic viral hepatitis since such a diagnosis might also account for the chronic pancreatitis, unless it was related to the cholelithiasis. However, Dr. Wagner's description favors a diagnosis of biliary pigment sludge related to hemolysis. Furthermore, the controversy over the extent of Beethoven's alcohol consumption and the absence of mention of pancreatic calcification weakens the case for an alcoholic etiology. On the other hand, Dr. Wagner's emphasis of bluish-green pigmentation of the liver, blackish pigmentation of the spleen, and an arteropathy of the hepatic vessels suggests the probability of hemochromatosis, which diagnosis is also in keeping with Beethoven's medical history. In this regard the composer's history of recurrent obscure abdominal pain, commencing in his third decade, is especially in keeping with hemochromatosis. As many as a third of patients present with recurrent abdominal pain, and eventually up to 40% of cases develop significant abdominal pain in the course of their disease. While some of these cases of abdominal pain have been attributed to hepatoma, ascites, pancreatitis, perisplenitis, or diabetic neuropathy, the majority remain ill-defined (32). Even so, the diagnosis of hemochromatosis remains unproved in the absence of a histological examination and measurement of hepatic iron concentration. It is proposed that the combined additive, toxic effects of alcohol and iron were the most likely cause of Beethoven's cirrhosis.

The clinical findings in 33 patients with progressive familial intrahepatic cholestasis (PFIC) are presented. Symptoms developed almost invariably before 6 months of age with severe pruritus and moderate jaundice. Other clinical findings included wheezing and nosebleeds, fat-soluble vitamin deficiency states, and cholelithiasis. Lower values for gamma-glutamyl transpeptidase, averaging 15 IU/L before the administration of phenobarbital, and cholesterol, which averaged 156 mg/dl, are helpful in distinguishing PFIC from other pediatric cholestatic liver diseases. Autosomal recessive inheritance is probable. Twenty-six patients are alive at 12.9 +/- 6.7 years of age, all having had successful surgical treatment, either partial biliary diversion (n = 17) or orthotopic liver transplantation (n = 10). Seven patients died at a mean age of 3.9 +/- 2.4 years, as a result of liver failure in two, hepatocellular carcinoma in two, and complications of liver transplantation in three.

The aim of the present study was to determine the pattern of structural and functional disorders encountered in an Asian gastroenterological clinic and to compare this pattern with findings from Western centres. Consecutive new patients (totalling 2384) attending the clinics of two consultant gastroenterologists were studied. Of these, 2141 suffered from gastroenterological problems. One thousand and sixty-three (49.6%) had structural diseases, the commoner ones being liver disease, peptic ulcer, malignancy, haemorrhoids and gallstones. The remainder who were found to have no structural disease (n = 1078; 50.4%) were deemed to have functional disorders including non-ulcer dyspepsia, irritable bowel, simple constipation and functional diarrhoea. The proportions of functional and structural disease were similar to those in the West. Major differences included a higher frequency of hepatoma and a lower frequency of inflammatory bowel disease and gastro-oesophageal reflux in the present series.

The medical records of 399 patients who underwent hepatic resection between January 1981 and December 1990 were reviewed. Information regarding the results of the hepatic resection in terms of the operative indication, operative procedure, operative morbidity, and mortality was abstracted. As of the end of 1990, a total of 402 hepatic resections had been completed, including those of 319 primary malignancies, 4 secondary malignancies, 2 gallbladder carcinomas, 42 cases of intrahepatic cholelithiasis, and 35 benign masses. Major hepatic resections were performed on 117 patients (29%), of whom 60 (51%) had histologically proven liver cirrhosis. Minor hepatic resections were performed on the remaining 285 patients (71%). Sepsis was the most frequent complication, which manifested primarily as wound infection (71 cases) or intra-abdominal infection (25 cases). Nonfatal hepatic failure occurred in nine patients with cirrhosis and one patient without cirrhosis. There were 38 operative deaths among the 402 hepatic resections, for an overall operative mortality of 9.4%; 25 of those deaths were due to hepatic failure after the operation, accounting for 66% of the total operative mortality. There was an increasing frequency of hepatic resection during the last 5 years. The indication for resection due to hepatocellular carcinoma increased from 87 to 195 cases. The cumulative data show a decrease in the incidence of complications and the operative mortality rate. In the most recent period, nonlethal postoperative complications occurred in 135 of 286 patients (47%). The overall 1-, 3-, and 5-year survival rates for 172 patients, excluding cases of operative mortality, palliative resection, and re-resection, were 71.0%, 39.8%, and 28.3%, respectively.

To evaluate the distribution of alpha-smooth muscle actin (alpha-SMA) positive cells in various liver diseases, we undertook an immunohistochemical study of liver diseases including chronic persistent hepatitis, chronic active hepatitis, liver cirrhosis, intrahepatic cholelithiasis and hepatocellular carcinoma. As a control, fetal livers (gestational age: 22-26 weeks) showed alpha-SMA positive cells along the blood vessels of the portal area, terminal hepatic venules and at perisinusoidal spaces. Perisinusoidal alpha-SMA positive cells were bipolar shaped and had round nuclei. In chronic persistent hepatitis, a few alpha-SMA positive cells were admixed with the inflammatory infiltrates mostly along the intact limiting plate. They were also detected multifocally in a linear pattern along the dilated sinusoid. In chronic active hepatitis, very strong alpha-SMA staining was detected at the site of piecemeal necrosis and adjacent lobules. A-SMA expression was decreased in some cases after interferon treatment. In cases of transplanted liver biopsies, expression of intralobular alpha-SMA was diffusely increased but showed no correlation with degree of acute rejection. Cirrhotic livers revealed strong alpha-SMA positivity in fibrous septae as well as in the perisinusoidal space of intact hepatocytes at the leading edge of fibrosis. Interlobular bile ducts were concentrically circumscribed by alpha-SMA positive cells in cases of intrahepatic cholelithiasis. In trabecular type hepatocellular carcinomas, most sinusoidal lining cells were positive for alpha-SMA. Most intralobular alpha-SMA positive cells represent, if not all, perisinusoidal cells (PSCs) which are involved in intralobular fibrogenesis in various liver diseases.(ABSTRACT TRUNCATED AT 250 WORDS)

The prevalence of primary liver cancer (PLC) varies throughout the world. It has been attributed to variations in incidence of the predominant histological type, hepatocellular carcinoma (HCC). The incidence of PLC types other than HCC such as cholangiocellular carcinoma (CCC) is far less known, especially in low-incidence areas. The aetiology of HCC and other PLC types is obscure, with the exception of the association between HCC and cirrhosis as well as chronic viral hepatitis. The present retrospective incidence and aetiology study concerns a well-defined population from a period with a high autopsy frequency. Preserved biopsy specimens were re-evaluated histopathologically and patient records were studied. Among 590 histologically verified cases of PLC, HCC constituted 90%, CCC 8% and a mixed form of these types 1%. At the end of the study period the annual age-standardised incidence rate of HCC was 3.6 cases per 100,000 inhabitants. Other PLC types were hepatoblastoma (n = 3), fibrolamellar carcinoma (n = 2), angiosarcoma (n = 1) and infantile haemangioendothelioma (n = 1), each constituting less than 1% of the PLC cases. Comparing HCC with CCC we found that cirrhosis (70%) and alcoholism (21%) was significantly more frequent in HCC, and cholelithiasis was significantly more common (60%) in patients with CCC. In the majority of the PLC cases with liver cirrhosis this disorder was unknown before diagnosis of the tumour.

alpha 2-macroglobulin-trypsin complexlike substance (MTLS) was determined in plasma of pancreatic and nonpancreatic diseases using a two-step enzyme immunoassay to study the diagnostic and pathophysiological significance of MTLS. Plasma levels of MTLS in acute pancreatitis (mean +/- SD = 265.6 +/- 346.2 ng/ ml, n = 9), calcified chronic pancreatitis (128.6 +/- 257.4, n = 13), and noncalcified chronic pancreatitis (13.5 +/- 12.5, n = 10) were significantly higher than that in controls (3.6 +/- 1.8, n = 81). In other diseases such as gastric cancer, hepatoma, diabetes mellitus, and gallstones, MTLS values were not different from those of control. Plasma MTLS values showed low correlation with serum trypsin, elastase 1, pancreatic amylase, lipase, and pancreatic secretory trypsin inhibitor (PSTI). The elevation of plasma MTLS values in acute pancreatitis suggests that plasma MTLS levels reflect that protease is inappropriately activated in pancreatic acinar cell and released into the circulation and that the determination of MTLS can be useful for diagnosis and pathophysiology of acute pancreatitis and chronic pancreatitis.
