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.

CH50 and the concentrations of C3, C4, C1 INH and factor B have been measured in sera from 34 control subjects and 178 patients with various hepatobiliary diseases, including primary biliary cirrhosis (PBC), chronic active hepatitis (CAH), cryptogenic cirrhosis (CC), alcoholic liver disease (ALD), Wilson's disease (WD), large duct biliary obstruction (LDBO) and viral hepatitis (VH). CH50 was decreased in CAH and CC. C3 was increased in PBC, LDBO and VH and decreased in CAH and CC. C4 was decreased in PBC, CAH, ALD and WD. C1 INH was increased in PBC, CAH, ALD, LDBO and VH. Factor B was increased in LDBO and VH and decreased in CC. In none of the patient groups was the mean C4 level increased or the mean C1 INH level decreased. All 5 indices of serum complement were lower in ascitic than nonascitic patients. Data on serum complement were similar in HBsAg positive and negative VH. Discriminant analysis facilitated separation of all the patient groups on the basis of complement data, except PBC and VA. Analysis of data using a within-group correlation matrix revealed a significant negative correlation between C4, the most discriminating variable of serum complement in CAH, and gamma-globulin concentration in CAH. The possible contribution of factors such as activation of complement, impaired hepatic synthesis of complement components, an acute phase response and cholestasis to altered serum complement profiles in different hepatobiliary diseases is discussed.

Percutaneous transphepatic cholangiography patterns of intrahepatic bile ducts in 134 patients were analysed. The majority of case material consisted of gallstone disease and complications of its surgery (44 cases) and secondary or primary neoplasms of the liver (40 cases). A satisfactory filling of the peripheral bile ducts was obtained after drainage of bile and with an injection of somewhat increased quantities of contrast medium into the biliary system. PTC was found to be highly effective in detecting space occupying lesions of neoplastic origin i.e. sensitivity-90 percent, specificity-95 percent, predictive value of a positive result-88 percent. PTC patterns of liver cirrhosis with concommitant extraheptic obstruction, chronic cholangitis, congenital ectasia of the bile ducts, liver abscesses are described. Although PTC is aimed primarily at the detection of nature and level of the extraheptic biliary obstruction there is no essential reason for neglecting its possibilities in recognizing intrahepatic disease.

Extrahepatic and intrahepatic biliary obstruction of different etiology were studied in 62 patients, who were investigated for the presence of lipoprotein X (Lp-X). It was found present in 19 of 20 cholestasis by lithiasis, in all three primary biliary cirrhosis patients, in 2 of 4 cirrhosis, in 5 of 13 hepatitis, in all three benign recurrent intrahepatic cholestasis and in 1 of 2 recurrent juandice of pregnancy. It was found in a Dubin Johnson. Lp-X disappeared in 4 patients within two weeks after relief of the obstruction. It was found in patients with cholestatic hepatitis during the first week of jaundice. It was found in the first 48 hours in three patients with cholestasis by lithiasis. Lp-X does not help in differential diagnosis between extrahepatic and intrahepatic biliary obstruction, but the time of its appearance could contribute to it in some cases. A word of caution is raised in indicating surgery in a cholestatic patient without the presence of Lp-X.

Three cases of septicemic shock after liver biopsy are reported. Escherichia coli was cultured in 2 patients and in 1 E. coli was cultured with Streptococcus viridans. All 3 patients were afebrile and had normal WBC counts before the procedure. Two had cholangitis and the 3rd had primary hepatoma and cirrhosis of the liver. Septicemic shock should be recognized as a rare complication of liver biopsy in patients with biliary obstruction.

Many reports have demonstrated an elevation of circulating carcinoembryonic antigen (CEA) in the majority of patients with alcoholic liver disease and, less frequently, in patients with nonalcoholic liver disease. Several explanations for this finding have been proposed, eg, increased production or release of CEA by the damaged liver, decreased hepatic metabolism, or diminished excretion of CEA of extrahepatic origin. In an attempt to clarify the mechanism of CEA elevation in liver disease, we have compared the CEA plasma level as measured by radioimmunoassay with CEA demonstrable in liver tissue by the indirect fluorescent antibody technique in 7 patients without significant changes in the liver biopsy specimen, 23 patients with alcoholic liver disease, and 16 patients with miscellaneous liver diseases such as acute or chronic nonalcoholic hepatitis or extrahepatic biliary obstruction. The mean CEA plasma level in patients with alcoholic liver disease was significantly higher than in patients with nonalcoholic liver disease (8.8 +/- 9.5 vs 2.7 +/- 2.5 ng/ml; P less than 0.02). In normal liver tissue, CEA was observed in the apical cytoplasm and along the luminal surface of bile duct epithelial cells, suggesting that under normal conditions CEA accumulates in and is excreted by bile ducts. In patients with alcoholic hepatitis and/or cirrhosis there was marked bile ductular proliferation and prominent cytoplasmic CEA-specific staining and both were associated with elevated CEA plasma levels in more than 80% of cases. In the group of miscellaneous liver diseases, bile ductule counts and CEA-specific staining did not correlate with CEA plasma levels. These observations suggest that proliferating bile ductules contribute to elevated plasma CEA in alcoholic patients.

Elevated circulating CEA levels occur in patients with benign gastrointestinal and hepatic disorders. These are usually less than 10 ng/ml. Of clinical importance is the influence of liver disease on the interpretation of CEA. At least 50% of patients with severe benign hepatic disease have elevated CEA levels, most often active alcoholic cirrhosis, and also chronic active and viral hepatitis, and cryptogenic and biliary cirrhosis. Patients with benign extrahepatic biliary obstruction may have increased plasma CEA, the highest in patients with co-existent cholangitis and especially liver abscess. The liver appears to be essential for the metabolism and/or excretion of CEA. Hence, liver work-up is needed to assess any patient with an elevated CEA. A damaged liver may further augment elevated CEA levels due to cancer. The increased circulating CEA observed in some patients with active ulcerative colitis tends to correlate with severity and extent of disease and usually returns to normal with remission. CEA levels also may be mildly elevated in patients with pancreatitis and in adults with colonic polyps. Smoking may contribute to the increased CEA levels seen in patients with alcoholic liver disease and pancreatitis. Therefore, in interpreting mildy elevated circulating CEA levels in patients with GI tract diseases, one must consider benign as well as malignant etiologies.

Computed tomography (CT) and radionuclide examinations of the liver and pancreas in 50 patients were compared retrospectively to evaluate their value as diagnostic tests. CT was superior to 75Se-selenomethionine in evaluating pancreatic disease. Both 99mTc-sulfur colloid scans and CT scans were sensitive detectors of liver masses; however, there were more false positive 99mTc-sulfur colloid scans (16% compared to 4%). CT was superior in detecting biliary obstruction and ascites, in assessing diseases that involved the liver extrinsically, and in evaluating the status of adjacent organs. 99mTc-sulfur colloid scans were more sensitive in detection of diffuse non-neoplastic liver diseases (cirrhosis, hepatitis, and cholangitis). Simultaneous interpretation of CT and radionuclide scans was often more helpful than independent interpretation, and the two techniques are therefore complementary.

A 68-year-old male underwent cholecystectomy with a normal operative wedge liver biopsy. Five months later he presented with secondary biliary cirrhosis and signs of portal hypertension and hepatocellular failure. At autopsy, a squamous cell carcinoma of the bile duct was found. This case represents an unusually rapid development of cirrhosis secondary to extrahepatic biliary obstruction with documentation of normal liver histology five months prior to his last admission.

The effect of flutamide, a potent nonsteroidal antiandrogen, on the metabolism of iv tracers of [3H]estradiol was studied in five patients with advanced prostate cancer. The drug produced no change in the percentage of the injected radioactivity recovered in urine or in the glucuronide or nonglucuronide conjugate fractions. Of the five individual metabolites that were quantitated, estrone, estradiol, and estriol were unaffected by flutamide, but the drug caused striking decreases in conversion of estradiol to 2-hydroxyestrone (4.0% vs. 7.4%) (P less than 0.005) and 2-methoxyestrone (1.1% vs. 2.6%; P less than 0.05); every one of the patients showed a marked fall in recovery of both of these compounds. This depression of the formation of 2-oxygenated metabolites is reminiscent of the findings in liver disease; the same abnormality occurs regularly in cirrhosis and frequently in extrahepatic biliary obstruction. Taken together with our previous studies of the effects of flutamide on testosterone and cortisol metabolism, this study demonstrates that flutamide produces multiple functional, reversible, cirrhosis-like disturbances of steroid metabolism. Because these disturbances are universal in the patients studied regardless of whether they had clinical responses to flutamide, we doubt that the steroid metabolic changes play a role in the therapeutic effect of the drug.
