We investigated the effect of rifampin on pruritus in 12 patients with chronic liver disease: non-A, non-B hepatitis (n = 3), alcoholic cirrhosis (n = 4), primary biliary cirrhosis (n = 4), and primary sclerosing cholangitis (n = 1). The study was a crossover, randomized, double-blind trial where placebo and drug were given daily in identical capsules (300 mg) for 2 weeks each, with a 1 week washout before and after each cycle. Mean duration of pruritus was 1.6 years (range of 4 months-5 years). Blood tests were done weekly and patients used a visual analogue scale (VAS) from 0 to 100 to mark their level of itchiness daily. Only transaminases were significantly lower while the patients were on rifampin. VAS scores were minimally affected by either rifampin or placebo. At the end of the trial, four patients said they were less itchy on rifampin and three preferred placebo. Of these seven patients, small falls in VAS scores occurred in two patients on rifampin and two on placebo; there was no change in the remaining three. There was little change in serum bile salt levels during the trial. No patient became jaundiced and deepening of jaundice did not occur in the four patients with initially elevated bilirubin. We conclude that a daily 300 mg dose of rifampin was not effective in relieving pruritus in a variety of chronic liver diseases.

The study of chronic liver disease has been hampered by insufficient information relative to the pathogenesis of the many forms of hepatitis. Consequently, well-designed treatment strategies are frequently lacking. Wilson's disease is characterised by excessive copper accumulation in the liver and other organs. While d-penicillamine is clearly effective, many patients may not tolerate its many adverse effects. Trientine, oral zinc and unithiol have all shown promise as therapeutic alternatives. Autoimmune chronic active hepatitis responds well to prednisone and azathioprine. Cyclosporin has also produced clinical improvement in several case reports but no comparison has yet been made with the current standard therapy. Recombinant interferon-alpha (IFN alpha) has demonstrated the ability to inhibit hepatitis B viral replication, and the combination of oral corticosteroids followed by IFN alpha is more effective than either agent alone in eliminating viral replication in patients with chronic active hepatitis B. Currently, primary sclerosing cholangitis (PSC) has no standard medical management, but corticosteroids and methotrexate may each have a future role in its treatment. Drug treatment for primary biliary cirrhosis (PBC) has been disappointing, and early reports of success with d-penicillamine were not confirmed in large well-controlled trials. While some reports of improvement with several agents have been described, larger studies are still needed. Alcoholic liver disease continues to be associated with significant morbidity and mortality and numerous investigators have researched several different medical avenues of treatment. Success reported with androgens and the antithyroid agent propylthiouracil in alcoholic liver disease will need confirmation by other research before these agents can be recommended for routine use. Finally, colchicine may prove to be effective in slowing the rate of fibrosis in cirrhosis, but this has yet to be conclusively proven.

The localization of the cholestatic factor (CF) was immunocytochemically investigated in liver biopsy specimens obtained from patients with various liver diseases. CF was detected in seven of nine patients with drug-induced liver injury, three of four with acute viral hepatitis, three of five with alcoholic liver injury and in the two patients with autoimmune hepatitis. Fourteen of these 15 CF-positive patients had jaundice in their clinical courses. CF was stained diffusely in the cytoplasm of hepatocytes throughout the lobules in a granular pattern. Electron-microscopically, it was localized on the ribosomes and polysomes as well as on the filamentous structures around the bile canaliculi. However, CF was not detected in liver specimens from normal controls and patients with primary biliary cirrhosis and extrahepatic biliary obstruction. These findings suggest that CF plays an important role in intrahepatic cholestasis in various liver diseases.

The methods to detect antimitochondrial antibodies (AMAs), which are characteristically positive in primary biliary cirrhosis (PBC), have some problems in technical difficulty, sensitivity and specificity. Based on the finding that one of the major antigens corresponding to AMAs was the E2 component of pyruvate dehydrogenase complex (PDH), a very simple enzyme-linked immunosorbent assay (ELISA) to detect anti-PDH antibody (anti-PDH) has been developed in this study. Among 68 patients with PBC, IgG class anti-PDH and IgM class anti-PDH were detected in 64 patients (94.1%) and in 55 patients (80.8%), respectively, while only three cases (4.4%) were both negative. Mean optical densities (O.D.) of sera from patients with PBC were 0.536 +/- 0.386 (mean +/- SD) in IgG class and 0.308 +/- 0.342 in IgM class. No positive cases were detected in the following patients by this ELISA: 20 patients with acute viral hepatitis, 24 with chronic persistent hepatitis, 32 with chronic active hepatitis, 19 with liver cirrhosis, 19 with hepatocellular carcinoma, 19 with acute intrahepatic cholestasis, 10 with autoimmune hepatitis, and six with systemic lupus erythematosus. Among nine AMAs negative cases with PBC by conventional indirect immunofluorescence (IF) assay, seven cases were found to be positive by this ELISA. The inter-assay coefficient of the variation of this method ranged from 4.9% to 5.8% and the intra-assay coefficient of variation from 3.8% to 5.1%. Therefore, this ELISA is useful for diagnosis of PBC.

Diagnostic judgement is usually based on recognition of patterns. Unfortunately more than three quantitative data cannot be judged simultaneously without help of mathematical methods. Working on laboratory reports, a clinician usually goes linearly through the columns and reduces quantitative to qualitative data. Therefore the medical decision process should be improved if data reduction is performed with the aid of mathematical methods for pattern recognition. A total of 191 consecutive outpatients with a tentative or proven diagnosis of hepatobiliary disease were examined clinically, clinically chemically and partly histologically. Nineteen clinical chemical parameters were determined. Prior to pattern cognition, a principal component analysis was performed. Using six factors, accounting for 72.4% of total variance, cluster analysis was done, applying a hierarchical algorithm for ascertaining a starting partition, followed by the k-means algorithm. The validity of the solution was scrutinized, and a stable structure was found with nine clusters. Patients with a rejected suspect of liver disease were mainly located in clusters 1, 6 and 7. Cluster 1 also contains patients with compensated cirrhosis without inflammation, idiopathic hyperbilirubinaemia, focal nodular hyperplasia and haemangioma of the liver. In contrast, one third of cirrhoses, all with inflammatory activity were assigned to cluster 5. Patients with primary biliary disease were distributed among clusters 2, 3 and 4. All malignant neoplasias were assigned to cluster 9. More than 50% of fatty livers were classified to cluster 7. Cluster 2 and 8 contain only one patient with primary biliary cirrhosis (cluster 2) and fatty liver hepatitis (cluster 8). The follow-up of 66 patients also showed clinically meaningful changes of cluster assignment.

Sera of patients with chronic hepatitis delta virus infection stained the nuclear periphery in indirect immunofluorescence. Using proteins of isolated nuclei, isolated nuclear matrices, the nuclear pore complex-lamina fraction and purified lamins A and C as antigen source in immunoblotting experiments, nuclear lamin C was identified as the reactive antigen. Most sera tested (8 of 10) recognized nuclear lamin C exclusively, but not the nuclear lamins A and B. Antibodies reacting with both nuclear lamins A and C, which share extensive sequence homologies, have been reported to occur in autoimmune hepatitis and primary biliary cirrhosis. The present findings suggest that the novel autoantibody associated with chronic hepatitis delta virus infection recognizes an epitope localized in the short carboxyterminal region of nuclear lamin C.

A new autoantibody to 210kDa microtubule associated protein (MAP) obtained from rabbit liver excrude was detected in the serum with various liver diseases and SLE. As there were no reports concerning autoantibodies to MAPs in animals and human, it may say that anti-210kDa MAP autoantibody we detected was a new cytoskeleton antibody. Using western blotting method, the anti-210kDa MAP autoantibody was frequently found in the patients with alcoholic liver diseases (52.5%), PBC (55.6%), autoimmune hepatitis (83.3%), SLE (71.4%) but rarely in the patients with viral liver diseases (26.4%) and none in normal controls at a serum dilution of 1:10. In addition, at a serum dilution of 1:100, the anti-210kDa MAP autoantibody was found in the patients with alcoholic liver diseases (22.5%), PBC (44.4%), autoimmune hepatitis (66.7%), SLE (71.4%), viral liver diseases (17.0%) and none in normal controls. It was confirmed that the anti-210kDa MAP autoantibody was frequently detected in cases of alcoholic liver diseases, PBC, autoimmune hepatitis and SLE than in those of viral liver diseases and normal control.

Liver metabolism and energetics of 24 patients with liver disease were studied using phosphorus-31 magnetic resonance spectroscopy. Significant abnormalities were detected in the majority of these patients. A striking diversity in metabolic patterns was observed. Patients with acute viral hepatitis had low liver phosphodiesters and high phosphomonoesters, possibly phosphocholine and phosphoethanolamine. In alcoholic hepatitis phosphomonoesters were raised. Intracellular inorganic phosphate and inorganic phosphate/ATP ratios were decreased in primary biliary cirrhosis and in some patients with hepatitis. These spectroscopic results were evaluated in respect of the pattern of liver damage and cellular regeneration. Liver tumours had raised phosphomonoesters and also showed evidence for altered spin-lattice relaxation of the phosphorus nucleus in various metabolites. In iron overload the liver ATP resonances were broadened. The line broadening correlated with the degree of iron overload suggesting the potential use of P-31 magnetic resonance spectroscopy for measuring liver iron.

We assessed the bilirubin reduction capacity of three different types of devices in vitro: a high-permeable membrane column for double-filtration plasmapheresis (DFP) (Evaflux 2A, Kuraray, Japan), and non-coated charcoal column for hemoperfusion (HP) (N-180, Asahi Medical, Japan), and ion-exchange columns for plasma adsorption (PA) (BR-350, Asahi Medical, Japan, and B-001, Kuraray, Japan). A column for DFP reduced the concentration of low-molecular proteins effectively such as plasma bilirubin and bile acids in an albumin-dependent manner. A charcoal column adsorbed low-molecular substances preferentially. But in these two columns, the loss of fibrinogen is a limiting factor for determining the processing plasma volume. Ion-exchange columns for PA adsorbed bile acids, disconjugated bilirubin, and monoconjugated bilirubin more efficiently compared with delta-bilirubin and unconjugated bilirubin. Pretreatment of the column with heparin reduced the loss of fibrinogen to less than 10%. We applied the BR-350 ion-exchange column in vivo for treatment of three patients with hyperbilirubinemia. After treatment, an alcoholic hepatitis patient with the hepatorenal syndrome (HRS) recovered from acute renal failure. However, in a patient with primary biliary cirrhosis and in a patient with fulminant hepatitis, the decrease of serum bilirubin was transient and no obvious beneficial responses were noted. The capacity and ability of the BR-350 column to adsorb plasma bilirubin was shown sufficient to treat deeply jaundiced patients, because 4 liters of the plasma of a patient with 108 mg/dl of initial total bilirubin concentration was able to be processed continuously without an obvious decrease in bilirubin adsorption capacity.(ABSTRACT TRUNCATED AT 250 WORDS)

Between April 1976 and March 1987, in an Internal Medicine department some 300 unguided percutaneous liver biopsies were performed, using the Tru-Cut excision needle. The procedure contributed to the diagnosis in 76.2% of the cases. In alcoholism-related pathology with its specific lesions, liver biopsy is particularly useful in diagnosing incipient fatty degeneration and hepatitis and helps in the prognosis of cirrhosis. In chronic hepatitis, it asserts the diagnosis and provides aetiological and prognostic data. The finding of granulomas at histology sometimes clinches a hitherto undecided diagnosis : sarcoidosis or tuberculosis? The diagnosis of drug-induced hepatitis rests on convergent clinical, biochemical and histological elements. In blood diseases, liver biopsy is of interest on three scores: it shows whether or not the liver is involved, detects intercurrent complications and evaluates the extent of the lesions before treatment. When performed after ultrasonography, it enables intrahepatic cholestasis to be recognized and extrahepatic cholestasis, unidentified by ultrasounds, to be suspected. In primary biliary cirrhosis, it confirms the diagnosis and informs on the severity and progressiveness of the disease. In hepatic cancers, liver biopsy has recently been superseded by computerized tomography and ultrasonography. Finally, it largely contributes to the diagnosis of overload disease and evaluates their activity and their impact on the liver.
