We describe the clinico-pathological characteristics of hepatic injury associated with the toxic-epidemic syndrome caused by the consumption of adulterated rapeseed oil. Of 842 toxic-epidemic syndrome patients admitted to our hospital between May, 1981, and January, 1982, 24.1% showed signs of liver involvement which was more frequent in women and in the fourth decade of life. No statistical significance was found in relation to alcohol consumption, treatment with potentially hepatotoxic antibiotics, or adult respiratory distress syndrome. Most (91.6%) patients with hepatic injury were asymptomatic; jaundice or abdominal pain was rarely noted. One patient died of acute liver failure following Budd-Chiari syndrome. Serum gamma-glutamyl transpeptidase activity was raised in all cases, alkaline phosphatase in 94.6%, and less frequently lactate dehydrogenase (80%), SGPT (84.7%), and SGOT (76%). Serum total bilirubin was usually normal (89.2%). The histologic lesion was similar to drug-induced cholestatic hepatitis. Lamellar inclusions, canalicular injury, giant mitochondria, and hyperplasia of the smooth endoplasmic reticulum were seen by electron microscopy. Ultrastructural signs of cholestasis were common (78.9%). The pathogenesis of this lesion is unknown; however, because of similarities with chlorpromazine-induced cholestatic hepatitis, we suggest that a combination of hypersensitivity and intrinsic hepatoxicity is a possible mechanism.

The function of maintaining concentrations (TAF) test was performed in patients with schizophrenia and hepatitis, and subjects with sleep deprivation. The results obtained are as follows: 1) Schizophrenia: It was suggested that TAF provided a reliable index of the effect and the amount of medicine as well as remissive condition. 2) Hepatitis: TAF tended to parallel the conditions of both acute and chronic hepatitis. A positive correlation was found between TAF-deviation (D) and gamma-glutamyl transpeptidase as well as lactate dehydrogenase (r = 0.682, 0.535, respectively). No significant correlation was found between TAF-level (L) and hepatic enzymes. 3) TAF-D of a 4-hour sleep group decreased significantly compared with that of a 8-hour sleep group. The lapse phenomenon of TAF curved line was observed in a 4-hour sleep group after 49 hours of sleep deprivation. It was considered that TAF was an objective index of pathological or physiological conditions.

Vinyl chloride monomer (VCM) is a suspected human carcinogen. Its metabolite, chloroethylene epoxide, is able to alkylate the DNA molecule and to produce single strand breakage (SSB). A total of 244 workers from 4 polyvinyl chloride (PVC) manufacturing factories were recruited to assess the SSB of their peripheral lymphocyte DNA. The method of alkaline unwinding and hydroxyapatite chromatography was used to detect and calculate frequencies of SSB. In addition, hepatitis B and C markers and the liver function of the workers were also examined. The worker's cumulative exposures to VCM were retrospectively constructed from the current monitoring data and each worker's job history. Multiple linear regression models were constructed to predict the worker's level of SSB and liver functions based on various exposure indices and variables, such as age, sex, smoking, drinking, and hepatitis markers. The results showed that current smoking and drinking status, and the presence of VCM exposures on the previous day were 3 major determinants of the level of SSB. Among the liver function tests, only gamma-glutamyl transpeptidase (GGT) was associated with current VCM exposures. In contrast, aspartate aminotransferase (AST), alkaline phosphatase (ALP) and alanine aminotransferase (ALT) were mainly affected by the presence of hepatitis B surface antigen (HBsAg) or anti-hepatitis C virus (anti-HCV). We conclude that GGT should be considered to be included in the regular health screening of VCM workers, and that the SSB method may not be suitable for long-term monitoring of cumulative exposure because of the quick DNA repair mechanism in humans.

The use of herbal and other "natural" health products by healthy and ill people is more common than is appreciated by many health care providers. Since most of these substances are not categorized as medicines, they are exempt from U.S. Government approval processes, and are essentially uncontrolled. In this article we describe a patient who developed painless jaundice, fatigue, and pruritus after taking chaparral tablets, 160 mg/day, for approximately 2 months. Serial liver biopsies and serum chemistries documented severe cholestasis and hepatocellular injury, i.e., a severe cholangiolitic hepatitis. Serum enzyme levels were markedly elevated: alk. phos. to four-fold, alanine aminotransferase and aspartate aminotransferase to 25-fold, total bilirubin to 30-fold, and gamma-glutamyl transpeptidase to 35-fold. Endoscopic retrograde cholangiopancreatography showed smooth, but severely narrowed biliary ducts without sclerosing cholangitis, distal obstruction, tumor, or stenosis. The diagnosis remained in doubt until the publication of two cases of chaparral hepatotoxicity. Because of the similarity of our patient's illness to those cases we concluded that chaparral was almost certainly the cause. Chaparral, also known as creosote or greasewood, is used by some practitioners to treat a diverse group of ailments including ethanol withdrawal. This report should heighten the awareness by primary care physicians and gastroenterologists that any chaparral herbal preparation is a potential hepatotoxin that can lead to serious illness.(ABSTRACT TRUNCATED AT 250 WORDS)

HBsAg-positive patients with end-stage renal failure have a high prevalence of asymptomatic chronic hepatitis. In order to determine the usefulness of hepatic cytology in the diagnosis of liver disease, the findings of hepatic needle core biopsy (NCB) and fine needle aspirative biopsy (FNAB) were compared in 15 HBsAg-positive uremic patients. The patients, aged 42 +/- 12 years, 14 males, were on hemodialysis for periods ranging from 13 to 105 months. The NCB was processed by standard histologic and immunohistochemical techniques and FNAB by the conventional technique, using the total corrected increment score (TCI). Plasma samples were collected for evaluation of hepatic function and for viral serologic tests. In 15 patients a diagnosis was made by NCB: normal, 7 cases; chronic persistent hepatitis, 4 cases; and chronic active hepatitis, 4 cases. When the patients were allocated into two groups according to the severity of the liver histologic findings [group I--minor changes (normal+chronic persistent hepatitis), 11 patients; group II--major changes (chronic active hepatitis), 4 patients], statistically higher values were found in the major changes group for alanine aminotransferase (49 +/- 33 vs. 24 +/- 11, p = 0.04), gamma-glutamyl transpeptidase [148 +/- 53 vs. 38 +/- 28, p < (minor) 0.02] and TCI (3.7 +/- 1.2 vs. 2.5 +/- 0.8, p = 0.04). In conclusion, liver FNAB can be useful as a screening procedure for the identification of liver histologic changes (minor or major) in uremic HBsAG-positive patients.

A 69-year-old Japanese female was admitted because of general fatigue. Laboratory data showed elevation of serum total bilirubin, transaminase, gamma-glutamyl transpeptidase, and creatinine levels. An immunological study revealed hypergammaglobulinemia, low titer of complement, and high titers of antinuclear antibody, anti-DNA antibody, and circulating immune complexes. Antibodies to parainfluenza virus 3 were positive. Histology of the liver disclosed numerous giant cell hepatocyte transformations with the lobular architecture being slightly distorted by portal inflammation and fibrosis. These findings led us to make a diagnosis of giant cell hepatitis associated with systemic lupus erythematosus. Prednisolone was effective in improving the anemia and the serum immunoglobulin, immune complex, and antinuclear antibody levels. The addition of cyclosporine to the initial corticosteroid therapy was also beneficial in decreasing the transaminase level and in improving liver histology. The patient died of acute pneumonitis and renal failure on the 166th day after admission. Parainfluenza virus 3 and autoimmune mechanisms were thus considered to be the causes of the giant cell hepatitis.

In early hepatic fibrosis, increased amounts of type III collagen are deposited. Persistently high serum concentrations of aminoterminal type III procollagen propeptide (PIIIP) correlate with the activity of the fibrogenic process. Another index for the detection of fibrosis, the PGA index, combines the prothrombin time, gamma-glutamyl transpeptidase activity, and serum apolipoprotein A1 concentration (the latter falls with progressive fibrosis). We compared PIIIP measurements and PGA index in patients with various histological forms of alcoholic liver disease (104), primary biliary cirrhosis (38), and chronic B virus hepatitis (27), and in healthy age-matched controls (30). The ability of each test to identify correctly patients with fibrosis or cirrhosis was assessed with receiver operating curves. The PGA index was much higher in all groups of patients with alcoholic liver disease than in controls (p < 0.0001). PIIIP concentrations were also substantially higher than in controls (p < 0.05 for fatty liver, p < 0.0001 for all other groups), especially in the group with alcoholic hepatitis and cirrhosis. For the detection of cirrhosis the PGA was 91% sensitive and 81% specific and the PIIIP concentration was 94% sensitive and 81% specific. The two tests combined had 85% sensitivity, but 93% specificity. Among patients with primary biliary cirrhosis, both PGA index and PIIIP concentration correlated well with the severity of the disease, determined by the Mayo score (r = 0.72 and 0.66 respectively). The combined tests were 96% sensitive for the detection of fibrosis. All patients with chronic B virus hepatitis had raised PGA and PIIIP values in comparison with controls (p < 0.0001) but there were no differences between subgroups. Substantially raised PIIIP concentrations thus identify the subgroup of alcoholic patients with both hepatitis and cirrhosis. The combination of PGA index and PIIIP concentration may be useful for targeting treatment with antifibrotic drugs and to reduce the need for liver biopsy.

We describe three men and two women, aged 18-50, with an occasional finding of increased aspartate and alanine aminotransferase and gamma-glutamyl transpeptidase levels in the absence of any drug treatment and past or current alcohol abuse. Two patients were overweight (body mass index 29 and 32, respectively) and physical examination was normal in all but one case. Tests for hepatitis A, B and C, Epstein-Barr virus, cytomegalovirus, toxoplasma and autoimmune hepatitis were negative and metabolic diseases (Wilson's disease, haemochromatosis, alpha-l-antitrypsin deficiency) were excluded by specific tests. Ultrasound liver scan revealed massive steatosis in all patients. Liver histology showed diffuse steatosis and parenchymal inflammation in all cases, with concomitant fibrosis and Mallory bodies in three of them. Findings were consistent with non-alcoholic steatohepatitis, a rare condition with potential progression to cirrhosis in a minority of cases. This disease, for which no treatment is currently available, must be considered in all subjects with elevated aminotransferases, in the absence of known causes of liver damage.

We report the case of a young HIV seropositive patient with severe hemophilia A who presented rapid liver failure related to his chronic C hepatitis. The patient had been receiving factor VIII:C clotting factor concentrates (mean 60,000 U/year) since 1975. In 1984 alanine aminotransferase presented abnormal levels. The CD4 lymphocyte count in 1991 was normal and ultrasonographic scan showed normal liver morphology. In 1991 the patient were found to be seropositive for HCV antibodies as detected by the ELISA method and confirmed by the RIBA method. One year later, a progressive increase in policlonal gamma-globulin and a decrease in the CD4+ lymphocyte count to below 500/muL were detected in concomitance with ultrasonographic evidence of a progressive increase in the longitudinal diameters of the liver and spleen and signs of liver inhomogeneity. A significant inverse correlation was observed between the increase in the longitudinal diameter of the liver and the decline in albumin levels, and between the increase in the longitudinal diameter of the liver and the drop in platelet count. Elevated levels of ammonemia, gamma-glutamyl transpeptidase, alkaline phosphatase and IgA were detected. Moreover, decreased levels of the C4 and C3 complement fractions were documented. At this time (1994), esophagogram and esophagogastroscopy evidenced varicosities in the lower esophageal section (stage F1). The patient died in 1995 March at the age of 29 years of sudden septic shock related to Pseudomonas aeruginosa infection.

In order to investigate the possibility of early discrimination of extrahepatic biliary atresia from other cholestatic diseases, a series of results of liver function tests in infants with cholestatic diseases were reviewed. The results of routine liver function tests (LFT) recorded in patients' charts were reviewed within 12 weeks after birth in 47 infants with extrahepatic biliary atresia (BA), 10 infants with neonatal hepatitis (NH) and 130 age-matched control infants (CO) without cholestatic diseases. The mean of each test value for each week after birth was derived from the actual data examined in each infant. No differences were observed between BA and CO in the levels of aminotransferases within 2 weeks after birth. Total bilirubin and direct bilirubin levels were significantly different between BA and CO within 1 week after birth (16.1 +/- 3.2 mg/dL vs 11.1 +/- 4.5 mg/dL, 4.6 +/- 2.6 mg/dL vs 0.7 +/- 0.3 mg/dL, respectively). The direct bilirubin-total bilirubin ratio exceeded 25% within the first week in BA. The individual values of direct bilirubin (DB) exceeded 2 mg/dL within the first week in all infants with BA, while none of the individual values exceeded 1.6 mg/dL in CO. Gamma-glutamyl transpeptidase levels were significantly different between BA and CO at 4 weeks (432 +/- 272 IU/L vs 79 +/- 43 IU/L) and thereafter; and were significantly different between BA and NH at 6 weeks (314 +/- 232 IU/I vs 69 +/- 58 IU/L) and thereafter. These data suggest that the determination of direct bilirubin within 1 week after birth can detect extrahepatic biliary atresia patients from those with physiologic jaundice, and gamma-glutamyl transpeptidase levels may discriminate BA from NH at no later than 6 weeks of age.
