A controlled clinical trial comparing 2-Mercapto-Priopionyl-Glycine (2-MPG) plus B12 vitamin with B12 vitamin alone in chronic liver disease has been conducted in seven hospitals in Italy. Patients were divided into two groups on the basis of liver histology; group I included 26 patients showing histological evidence for chronic persistent hepatitis (C.P.H.) (according to De Groote et al.) whereas group II consisted of 54 patients with chronic aggressive hepatitis (C.A.H.) or compensated liver cirrhosis. Patients of each group were randomly allocated to 2-MPG plus B12 vitamin, or to placebo plus B12 vitamin, in a double-blind way. The drug (or placebo) was diluted in 500 ml of 10% Levulose, and administered intravenously; 1000 gamma of B12 vitamin were added to each bottle. Patients in the 2-MPG group received 2.5 gms of the drug daily; the treatment lasted for 30 days. The following parameters were checked in all patients on admission, and repeated at the end of treatment: Serum bilirubin, serum Cholesterol, A.P., BSP retention, Prothrombin time, S-GOT, S-GPT, Gamma-GT, Total serum Protein, serum electrophoresis, Immunoglobulins. Patients given 2-MPG showed significant decreases of serum transaminases, and improvement of BSP retention.

The levels of C3, cholinesterase, albumin and prothrombin were determined in 46 patients (27 males and 19 females) - 26 with cirrhosis of the liver, 9 with acute hepatitis, 6 with chronic aggressive hepatitis, 1 with chronic persistent hepatitis and 4 with fatty liver. In all patients and, particularly in those with cirrhotic liver, it was shown that the normal or pathological level of serum C 3 is related both qualitatively and quantitatively to the normal or pathological levels of cholinesterase, albumin, and prothrombin. The percentage in which the levels of these four parameters were pathological was considerably higher in the cases with hepatic coma than in the cases without hepatic coma. The determination of the range of confidence for the 4 parameters showed that, in the patients with hepatic coma, cholinesterase reacted most sensitively to liver damage (0.5 - 0.94) followed by C3 and prothrombin (0.33 - 0.81). Also in the cases without hepatic coma, cholinesterase was the most sensitive indicator (0.05 - 0.29), followed by prothrombin (0.03 - 0.24), albumin and C3 (0.00-0.16).

Antibody against hepatitis C virus (anti-HCV) was tested in 658 cases of hepatitis and liver diseases with ELISA, ninety of these cases were positive, with a total infection rate of 13.68% (90/658). The positive rate of anti-HCV was highest in patients with chronic severe hepatitis (33.78%) and CAH accompanied by cirrhosis of liver(31.58%). The infection rate in other types of hepatic diseases in order of frequency was as follows: fulminant hepatitis (18.18%), CAH without cirrhosis (15.13%), subacute severe hepatitis (13.43%), CPH (5.88%), primary hepatocellular carcinoma (3.85%), and acute hepatitis (2.42%). Serological markers of HBV infection were detectable concomitantly in 77 of the 90 cases who were anti-HCV positive, but there was no evidence of mutual inhibition of viral replication. There was neither appreciable difference in the level of hyperbilirubinemia in cases of hepatitis with or without anti-HCV, nor significant diversity in the number of death between cases of severe hepatitis with and without anti-HCV.

An ABC immunohistochemical study of the expression of cytokeratin (CK19 and CK18) was carried out in 315 cases of HBV-caused hepatitis, early-cirrhotic and cirrhotic livers. It was shown that hepatocytes in 73% of chronic active hepatitis (CAH) (80/110) and 81% of early-cirrhotic and cirrhotic livers (117/144) expressed CK19 (the abnormal CK expression), which could be of help in differentiating CAH from chronic persistent hepatitis, subtype CAH (mild, moderate to severe type) and in determining the activity of early-cirrhotic and cirrhotic livers. The abnormal CK expression was shown to be closely related to the activity of liver disorders. The CK19 expression in hepatocytes had the closest relations with the piece-meal necrosis of hepatocytes, isolation of hepatocytes into groups by connective tissue, and fibrosis. It is suggested that CK19 expression may be one of the local reactions to the piece-meal necrosis of hepatocytes.

Orthotopic liver transplantation (OLT) was performed for liver failure related to hepatitis non-A, non-B (HNANB) or hepatitis C (HCV) infections in 12 patients. Of those, 8 patients had chronic and 4 acute hepatic failure. To determine the incidence of recurrent infection, the clinical course, histological findings and serological HCV markers (HCV-RNA and detection of anti HCV antibodies, respectively) were comparatively studied in these patients. Recurrent infection was apparent in 5 of 6 patients transplanted for liver cirrhosis attributable to chronic HCV infection and with HCV-RNA detectable in serum. The clinical course of infection after OLT varied considerably. Chronic active hepatitis, progressing to liver cirrhosis 13 months postoperatively and an acute hepatitis, resolving spontaneously were seen in one case each. Recurrent infection led to chronic persistent hepatitis in the remainder. None of the patients with acute liver failure experienced recurrent infection. HCV-RNA was detectable in all the patients after OLT, with HCV-RNA present pretransplant, however the presence of HCV-RNA in serum was not necessarily associated with clinical illness.

As part of a study of community-acquired non-A, non-B hepatitis, liver biopsy specimens of 29 anti-HCV positive and four anti-HCV negative patients were evaluated in order to characterize the histopathologic changes of chronic hepatitis C. Liver biopsies were performed 6 to 46 mo after onset of the disease and repeat biopsies were obtained in 10 anti-HCV positive patients. The histologic diagnoses were chronic persistent hepatitis (45%), chronic active hepatitis (35%), and chronic lobular hepatitis (21%). Irrespective of the tissue diagnosis, the majority of the patients showed characteristic histologic abnormalities in the liver, particularly damage of the small and medium-sized bile ducts (76%), lymphoid aggregates in portal tracts (45%), enlarged macrophages (48%), and steatosis (31%). In 59% of the patients, two or more of these histologic abnormalities were combined. Similar histologic changes have previously been observed in non-A, non-B hepatitis, but only uncommonly in hepatitis A or hepatitis B. We conclude that the histopathologic findings in chronic hepatitis C are highly characteristic, although not pathognomonic.(ABSTRACT TRUNCATED AT 250 WORDS)

It has recently been shown that ursodeoxycholic acid administration improves liver function tests in patients with chronic liver diseases. Aim of the present study was to evaluate an ursodeoxycholic acid derivative (bis-hemisuccinate bisodic salt Ursodamor, Farmaceutici Damor, Napoli) in patients with chronic hepatitis. Forty patients (15 M, 25 F) with biopsy proven chronic liver disease participated to the study. Patients were randomly allocated to two treatment groups. Twenty patients (4 PBC, 11 CAH/CPH, 5 cirrhosis) received the ursodeoxycholic acid derivate at the dose of 600 mg/day, while 20 patients (1 PBC, 11 CAH/CPH, 8 cirrhosis) received a placebo. For both groups the treatment period was six months. ALT serum levels were significantly reduced in the treated group (from 84 +/- 14 to 62 +/- 14 p less than 0.0005) while no significant change was observed in the placebo group. In the treated group but not in the placebo group alkaline phosphatases and gamma-GT were also significantly reduced (from 268 +/- 56 to 160 +/- 23 p less than 0.0005 and from 79 +/- 21 to 45 +/- 10 p less than 0.0005). In conclusion, our results suggest that the administration of the ursodeoxycholic acid derivate, bis-hemisuccinate, bisodic salt, improves liver function tests in patients with chronic liver hepatitis. Similarly to ursodeoxycholic acid this new derivate probably interferes with bile acid pool composition by replacing the more detergent and probably more toxic endogenous bile acid.

Porphyria cutanea tarda in human beings is believed to be due to reduced hepatic uroporphyrinogen decarboxylase activity. However, extrinsic factors such as alcohol abuse and drug intake are required for clinical manifestation of the disease. In addition to typical cutaneous lesions, patients with porphyria cutanea tarda usually have chronic liver disease and moderate iron overload. Of 74 Italian patients with porphyria cutanea tarda, hepatitis C virus antibodies were detected in 76% by enzyme-linked immunoassay and in 82% by recombinant immunoblot assay. Viral genome, studied with nested polymerase chain reaction, was found in the sera of 49 subjects--47 positive and 2 indeterminate on recombinant immunoblot assay. Five percent of the patients were HBsAg-positive, and about 40% had had past hepatitis B contacts. Alcohol abuse was present in 38%. Liver biopsies performed in 42 patients showed chronic persistent hepatitis in 7 patients, chronic active hepatitis in 22 patients, fibrosis in three patients and cirrhosis in 10 patients. Hepatitis C virus antibody was detected in 100% of patients with chronic active hepatitis and in about 80% of all other groups. Alcohol abuse was more frequent in patients with cirrhosis (80%) than in the other groups. In Italian patients with porphyria cutanea tarda, the prevalence of hepatitis C virus infection was very high, comparable to that in non-A, non-B hepatitis and high-risk patient groups. Hepatitis C virus is probably the main pathogenetic factor of the liver disease of patients with porphyria cutanea tarda.

A study of anti-HCV in the sera of different populations of Beijing was conducted. Of the general population, 2.1% (9/438) were anti-HCV positive, and of the patients that underwent blood transfusion 11.1% (6/54) were anti-HCV positive. Among patients with chronic liver diseases, anti-HCV was positive in 10.5% (36/342) of patients with chronic persistent hepatitis (CPH), 12.1% (13/107) of those with chronic active hepatitis (CAH), 42.6% (63/148) of those with liver cirrhosis (LC) and 38.4% (20/52) of those with hepatocellular carcinoma (HCC). HBsAg and anti-HCV were both positive in none of the general population, in 6.7% (23/342) of patients with CPH, in 8.4% (9/107) of those with CAH, in 31.1% (46/148) of those with LC and in 28.9% (15/52) of those with HCC. In the development of hepatitis into chronicity, detection of anti-HCV is of great significance. It was found that HBV-HCV coinfection made the condition of the patients with hepatitis worsened and it had close relations with hepatocellular carcinoma. Investigation in subjects below the age of 35 in the general population and in patients with chronic hepatitis indicate that besides the mother-to-infant route or the route of blood transfusion, HCV has other routes of propagation.

Fifty-two patients on regular haemodialysis at our institution were evaluated for the presence of HCV infection. Evaluation included detailed history, clinical examination, and monthly screening for anti-HCV antibody, liver enzymes (ALT, AST), serum iron and ferritin. Also, three-monthly screening for other viral markers, HBV (HBsAg, HBsAb, HBcAb), CMV (IgG and IgM), EBV, and HIV. Anti-HCV antibody was found in 21 patients (40.4%). There was a significant (P less than 0.05) relationship between presence of anti-HCV antibody and proportion of patients who received blood transfusion. During a 12-month follow-up, four (11.4%) patients seroconverted to be Anti-HCV positive while one case (4.8%) seroconverted to be anti-HCV negative. The frequency of elevation of liver enzymes was significantly higher in Anti-HCV positive cases (14/18) than in negative cases (11/28, P = 0.01). Evaluation of liver biopsies of 13 patients showed chronic persistent hepatitis in six and chronic active hepatitis in seven cases. We concluded that hepatitis C is a common problem among chronic haemodialysis patients at our institution; HCV infection is documented in 70% of all clinically diagnosed NANB hepatitis. Presence of anti-HCV antibodies cannot differentiate between active and past infection and cases with early HCV infection can be missed when relying on the mere detection of anti-HCV antibodies.
