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).

There was an epidemic of non-A non-B hepatitis in a small area of a town in the central part of Japan, which began with an outbreak of several patients in 1981 and then spread extensively with the result that about one third of the inhabitants showed abnormality in serum liver function tests at the health check performed in 1985. We determined histological diagnoses on that occasion for 167 individuals of the abnormal population and recently assayed antibodies against hepatitis C virus (HCV) for most of their sera left available. Histologically, chronic active hepatitis (CAH) was the major pattern, accounting for 59.3% (99 cases) of the total. Others were chronic persistent hepatitis (CPH) (13.2%), chronic lobular hepatitis (CLH) (16.2%), liver cirrhosis (LC) (6.6%) and fatty liver (4.8%). In the serological studies, the newly developed system to detect antibodies against the viral core protein p 22 was found to be much more sensitive than the conventional system to detect anti C 100-3 antibodies. By using these two methods in combination, we found that 82% were antibody-positive, indicating strong implication of HCV in this epidemic. This was further supported by direct detection of the viral genome in patients' sera by polymerase chain reaction following reverse transcription. We further found a strong correlation between the histological inflammatory activity and the antibody prevalence, since nearly all (97.6%) of the CAH cases were antibody-positive by at least either of the antibody assays, while only about 50% were positive in the less active cases such as CPH and CLH.

We present pathologic findings for 52 livers (51 autopsy specimens and one wedge biopsy specimen) from patients with systemic lupus erythematosus (SLE). Hepatic congestion was the most common disease (40 livers), followed by fatty liver (38), arteritis (11), cholestasis (nine), peliosis hepatis (six), chronic persistent hepatitis (six), nonspecific reactive hepatitis (five), cholangiolitis (four), nodular regenerative hyperplasia of the liver (three), and hemangioma (three). The data obtained here suggest that arteritis of the SLE liver is more common than has been recognized previously. One patient had hepatic infarction complications induced by arteritis. On the basis of the findings in the present study and a review of the literature, we suggest that hepatic infarction resulting from arteritis is rare in SLE. On the other hand, while occurrence of nodular regenerative hyperplasia of the liver in SLE patients has been considered to be rare, our findings suggest that it may be more common than has been recognized previously. Although congestion and cholestasis may be acute terminal illnesses, fatty change is considered to be specific to the SLE liver. Statistical analysis indicates that exposure to a large dosage of glucocorticoids is a significant factor in the etiology of severe fatty liver. In addition, our review of Japanese autopsy registry data for 1,468 patients with SLE indicates that the incidence of chronic liver diseases in SLE autopsy cases is as follows: chronic hepatitis, 2.4%; cirrhosis, 1.1%; and liver fibrosis, 0.8%.

A relatively noninvasive method is needed to evaluate the hepatic blood flow of patients with liver disease. We used per-rectal portal scintigraphy with 133Xe, and analysed the time-activity curves of the liver and portal vein. To do this, wash-out curves of the liver were plotted, and the hepatic blood flow and the ratio of the blood flow to the right lobe of the liver to that to the left lobe (R/L ratio) were calculated. The mean hepatic blood flow was 137 +/- 23 ml/100 g/min for four patients with fatty liver, 139 +/- 16 ml/100 g/min for seven patients with chronic persistent hepatitis, 120 +/- 15 ml/100 g/min for ten patients with chronic aggressive hepatitis, and 75 +/- 21 ml/100 g/min for 14 patients with cirrhosis. All seven patients with hepatic blood flow that was less than 100 ml/100 g/min and an R/L ratio less than 1.0 had cirrhosis. Only two of the 22 patients with hepatic blood flow that was greater than 100 ml/100 g/min and an R/L ratio greater than 1.0 had cirrhosis. Per-rectal portal scintigraphy can be used to measure the hepatic blood flow, but it was not useful for the diagnosis of fatty liver.

Serum level of osteocalcin (OC) is believed to be a specific biochemical parameter of bone formation. Decreased serum OC has been reported in alcohol-intoxicated subjects, in patients with primary biliary cirrhosis and in patients with chronic alcoholic liver disease. The question was, whether lower OC level could be detected in patients with nonalcoholic and non-cholestatic chronic liver disease. The serum OC was measured by RIA developed in our laboratory. Results were compared to age and sex matched controls. Decreased OC level was found in 35 out of 47 (74%) patients with non-alcoholic and non-cholestatic liver disease as chronic persistent hepatitis, chronic active hepatitis, fatty liver and cirrhosis, in 21 out of 26 (80%) patients with alcoholic liver disease and in 8 out of 15 (53%) primary biliary cirrhosis. None of the patients had elevated value. There was no correlation between the decreased OC level and the duration or severity of the liver disease and the laboratory parameters as bilirubin, AST, ALT, alkaline phosphatase, albumin, prothrombin, and serum 25-OH-D3 vitamin level. Decreased OC was found also in the patients without cirrhosis. The possible causes are discussed. Relying upon these findings it is supposed that chronic liver disease by itself can influence the osteoblast activity also by some unknown mechanism.

We studied the prevalence of anti-HCV in 585 sera from various individuals, using enzyme immunoassay (EIA, Abbott Lab.). Anti-HCV was detected in 16 (10.7%) out of the 150 patients with HBsAg positive liver diseases diagnosed by liver biopsy and they consisted of none out of 10 acute viral hepatitis, 3 out of 15 chronic persistent hepatitis, 4 out of 50 chronic active hepatitis, 2 out of 32 liver cirrhosis, and 7 out of 43 hepatocellular carcinoma. Anti-HCV was detected in 43 (45.3%) out of 95 patients with HBsAg negative liver diseases diagnosed by liver biopsy and they consisted of 5 out of 8 acute viral hepatitis, 2 out of 10 chronic persistent hepatitis, 17 out of 30 chronic active hepatitis, 4 out of 15 liver cirrhosis, and 15 out of 32 hepatocellular carcinoma. Anti-HCV was detected in 22 (38.6%) out of 57 hemodialysis patients, in 3 (6.7%) out of 45 kidney transplants, in 2 (11.1%) out of 18 fatty liver diagnosed by liver biopsy, in 2 (1.3%) out of 150 healthy blood donors, in none out of 40 healthy volunteers, in 6 (31.6%) out of 19 rheumatoid arthritis and in 6 (54.5%) out of 11 systemic lupus erythematosis cases. There were familial clusters of chronic liver diseases in 4.7% of patients with HBsAg negative/anti-HCV positive chronic liver diseases, while in 19.4% of patients with HBsAg positive/anti-HCV negative liver diseases. Incidence of anti-HCV within patients with HBsAg positive liver diseases was higher in HBsAg negative patients than in HBsAg positive patients (17.6% and 10.3%, respectively).(ABSTRACT TRUNCATED AT 250 WORDS)

Volumetric comparisons of portions of liver and spleen were performed in patients with chronic liver diseases to determine their diagnostic value. Volumetric ratios of liver and spleen were determined by CT examination in 34 normal subjects and 125 consecutive patients with histologically proved liver cirrhosis, chronic active hepatitis, chronic persistent hepatitis, acute hepatitis, or fatty liver. Ratios of caudate lobe, spleen, and lateral segment of the left lobe of the liver to the remainder of the liver, right lobe and medial segment of the left lobe (RL+LM), were calculated. The product of caudate lobe/RL+LM and spleen/RL+LM was of value in differentiating liver cirrhosis from other liver disease, with a sensitivity of 60%, specificity of 98%, and accuracy of 86%. The same ratios differentiated liver cirrhosis and chronic active hepatitis from other liver diseases with a sensitivity of 79%, specificity of 100%, and accuracy of 90%. Volumetric ratio measurements are useful in the diagnosis of cirrhosis and chronic active hepatitis.

Essential mixed cryoglobulinemia (EMC) is a syndrome characterized by cryoglobulinemia and clinical features including purpura, arthralgia, asthenia (Meltzer-Franklin syndrome) without evidence of any systemic disease Liver involvement in the course of EMC is described in 50-84% of patients. It consists of mild silent hepatosplenomegaly and slightly rise of serum amino transferase. Eleven patients with clinical and laboratory findings suggestive for EMC (five type II and six type III) underwent percutaneous liver biopsy to evaluate the degree of liver involvement. Two liver cirrhosis, two chronic active hepatitis, one chronic persistent hepatitis and a case of hepatic steatosis were found. A type III cryoglobulinemia was present in four of the six patients with liver involvement. All the patients were Hbs Ag negative but three of them were Hbs Ab positive. The pathogenesis of liver involvement in the course of EMC is still now uncertain. The authors believe that a previous HBV infection plays no role in the pathogenesis of EMC syndrome. This syndrome must be considered different from mixed cryoglobulinemia secondary to chronic liver disease. They suggest that liver biopsy is mandatory during the course of EMC even when clinical and laboratory data are silent.

For the detection of mild liver disease (acute viral hepatitis, chronic persistent hepatitis, fatty liver) serum bile acids levels have not proved to be superior to transaminases or other common liver tests with almost similar sensitivity and/or specificity. Indeed it has been possible to show in patients with compensated cirrhosis of the liver that the serum bile acids concentration is related to the degree of intrahepatic shunts and that there was a significant relationship between the fasting serum bile acids and the intrinsic clearance of ICG. Measurement of serum bile acids appear to be more sensitive for detection of cirrhosis than commonly used tests. The elevation of bile acids concentration in cirrhotic patients is thought to result from a reduced hepatic clearance and/or from portosystemic shunting. In order to determine the role of serum bile acid estimation in the indirect assessment of portal hypertension, fasting and two-hour postprandial serum bile acids concentration were measured in 36 patients with liver cirrhosis, classified according to Child-Pugh's criteria. Real time ultrasonography, esophagogastroscopy and static liver scintigraphy of the liver were carried out in all patients. The size of esophageal varices, the portal vein and its related structure, the nuclear criteria were graded according to the common methods. Between the clinical findings, splenomegaly, was noted and graded, though the size of spleen does not correlate well with the level of portal pressure. In our patients a good correlation (p less than 0.001) existed between the two hour postprandial bile acids concentration and ultrasonographic findings of portal hypertension. Fasting serum bile acids (SBA) were significantly higher in severe than in mild liver cirrhosis according to Pugh's criteria (p less than 0.001). In conclusion we think that SBA concentrations have a great prognostic value in assessment of major complications (upper gastrointestinal hemorrhage particularly). The reduced liver blood flow, for intra-and extrahepatic porto-systemic shuntings, is probably the main cause of reduced hepatic clearance of bile acids.

Urinary neopterin excretion was measured in 26 patients with histologically proven chronic non-A, non-B hepatitis (16 chronic persistent hepatitis, 10 chronic active hepatitis) and in 16 patients with steatosis. The potential of neopterin levels to discriminate between the two patient groups was compared with that of standard laboratory variables. Neopterin levels and triglycerides were shown to be the best variables for discriminating between the hepatitis and fatty liver patients, neopterin being the more specific of the two. Neopterin excretion in chronic persistent hepatitis was not statistically different from that in chronic active hepatitis. In the absence of specific tests, increased neopterin excretion seems to be a useful marker for diagnosing chronic non-A, non-B hepatitis and particularly in differentiating it from fatty liver.
