We report a case of acute hepatitis in a 28-year-old male with acquired rubella infection. Serological tests revealed acute rubella virus infection and ruled out infection by other common viruses, including type A and type B hepatitis viruses. The patient showed not only marked increase of lactate dehydrogenase (LDH) activity, with only slight liver dysfunction, but also platelet and kidney injury, suggesting systemic rubella virus infection. Because the liver dysfunction was slight, liver biopsy was not performed. When a patient has mild, transient hepatitis accompanied by high LDH activity in comparison with both aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels, we should take a common viral infection such as rubella into consideration when making a diagnosis.

Forty two cases of confirmed hepatitis C virus (HCV) infection with available liver histology were studied. Most patients, 23 of 42 (55%) had abnormal liver function tests but 19 of 42 (45%) had persistently normal liver transaminases (mean aspartate transaminase (AST) 24.1 IU/l, mean follow up 10 months). Histological examinations in the group with normal AST activities were normal in two of 19 (11%), showed non-specific reactive hepatitis in eight of 19 (42%), chronic persistent hepatitis in six of 19 (31%), and chronic active hepatitis in three of 19 (16%). Twenty three of 42 (55%) had either persistently or temporary raised liver transaminases (mean AST 96.2 IU/l, mean follow up 16 months). Histological examinations in this second group with abnormal liver biochemistry showed reactive hepatitis in five of 23 (22%), chronic persistent hepatitis in six of 23 (26%), chronic active hepatitis in 10 of 23 (43%), and cirrhosis in two (9%). Average alcohol intake was significantly higher in the group within abnormal liver function (17.8 v 6.4 units, p = 0.01). Although serious pathology was more frequent in the abnormal transaminase group, significant liver pathology (chronic persistent hepatitis or chronic active hepatitis) was found in nine of 19 (47%) of cases with repeatedly normal transaminases. Liver biopsy is advised in all cases of chronic hepatitis C infection to accurately assess both the degree of fibrosis and the current activity of the disease.

Scrub typhus is an acute febrile illness that generally causes non-specific symptoms and signs of which fever is the most common. It is one of the causes of "fevers of unknown origin" in the Asia-Pacific region. The relationship between hepatic dysfunction and scrub typhus has been given little attention in the literature. From 1982 to 1993, 47 patients diagnosed with scrub typhus at Tri-Service General Hospital, Taipei, were studied, with attention being given to hepatic dysfunction. The medical records of these patients were reviewed thoroughly. Hepatic dysfunction occurred in 77% (36/47) of patients. Among the liver function parameters, the percentage of abnormality was 74.5% for aspartate aminotransferase, 74.5% for alanine aminotransferase, 57.4% for alkaline phosphatase, 44.7% for lactate dehydrogenase and 44.7% for serum bilirubin. Six patients presented with a picture of true hepatitis similar to acute viral hepatitis. The results indicate that hepatocellular damage does occur in scrub typhus, and is perhaps, more common than previously realized. We recommend that the differential diagnosis of patients from high-risk groups and endemic areas who present with hepatitis-like symptoms should include examination for scrub typhus.

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 pharmacokinetic behavior of glycyrrhizin in four patients with acute hepatitis (hepatitis group) and six patients with liver cirrhosis (cirrhosis group) receiving chronically an IV administration of a 120 mg dose once a day or once every other day of glycyrrhizin was investigated. The plasma concentration of glycyrrhizin declined monoexponentially in both groups. The elimination half-life (t1/2) for glycyrrhizin in the hepatitis and cirrhosis groups varied significantly in the range of 2.7-7.6 h and 6.2-40.1 h, and the total body clearance (CLtot) in the range of 2.8-23.2 mL h-1 kg-1 and 1.4-12.9 mL h-1 kg-1, respectively. The t1/2 for glycyrrhizin in the hepatitis and the cirrhosis groups was about twice and eight times that in normal subjects, respectively, as reported previously, and CLtot values were about 0.7 and 0.23 times that in normal subjects, respectively. There was significant correlation between the CLtot and hepatic function (aspartate aminotransferase and alanine aminotransferase in serum) in both patient groups. With improvement of the liver function, the CLtot for glycyrrhizin increased from 2.8 ml h-1 kg-1 to 11.4 mL h-1 kg-1, and the t1/2 shortened from 7.6 h to 3.4 h. These findings indicated that the variation of pharmacokinetic behaviour of glycyrrhizin in both groups was closely related to the extent of the liver function.

Long-Evans Cinnamon (LEC) rats that develop spontaneous hepatitis due to an inherently abnormal Cu metabolism have recently been established. This investigation concerns the effects of a Cu-deficient diet on the Cu metabolism linked to hepatic injury in LEC rats. The hepatic Cu concentration at 30 days after birth was 94 +/- 4 Cu micrograms/g liver in LEC rats, whereas that of Fischer rats at the same age was 7 +/- 1 Cu micrograms/g. From 30 days after birth, all rats were fed a semisynthetic diet with two different levels of Cu, 0.5 or 30 micrograms/g food, for 35 days. In LEC rats fed a Cu-deficient diet (0.5 microgram/g), the hepatic Cu concentration was 39 +/- 7 micrograms/g. The Cu-normal diet (30 micrograms/g) LEC group had a concentration of 357 +/- 15 micrograms/g in the hepatic Cu. The group had significantly higher aspartate aminotransferase (ASAT), alanine aminotransferase (ALAT) and gamma-glutamyl transferase (GGT) levels than did the LEC rats given the Cu-deficient diet. These results suggest that the occurrence of acute hepatitis in LEC rats can be prevented by feeding the animals a Cu-deficient diet.

Seven horses developed clinical or subclinical hepatitis 48 to 87 days after administration of tetanus antitoxin. One horse had mildly high hepatic enzyme activity 120 days after inoculation with tetanus antitoxin. The first horse developed signs of depression, lethargy, and anorexia. During hospitalization, signs of hepatoencephalopathy were noticed, and laboratory data were consistent with hepatic disease. Another horse that was found dead had gross and histologic lesions compatible with serum hepatitis. Screening of serum gamma-glutamyltransferase (GGT) and aspartate transaminase activities were used to investigate the remaining horses in the herd. High GGT activities (71 to 206 IU/L) were detected in 5 additional herd members. These horses appeared clinically normal, apart from 2 reports of nasal photosensitization and an aborted fetus. In 3 horses, high serum GGT activity persisted over a 44-day testing period. All affected horses had been given tetanus antitoxin within 12 hours of parturition, and a common source of vaccine was identified for 7 horses. Findings in this group of horses indicate that clinical and subclinical serum hepatitis can develop after administration of tetanus antitoxin.

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)

Groups of 10 male Hartley guinea pigs were exposed to 3.0, 2.0, 1.0, or 0.1% (v/v) 1,1-Dichloro-2,2,2-trifluoroethane (HCFC-123) or 1.0% (v/v) halothane by inhalation for 4 hr. A sixth group of 10 guinea pigs received only air. All animals were sacrificed 48 hr postexposure. Gross and histopathologic examination of the liver, heart, and kidney and routine hematology and clinical chemistry analyses [including isocitrate dehydrogenase (ICDH)] were done on all guinea pigs. Lesions related to HCFC-123 and halothane exposure were limited to the liver and included centrolobular vacuolar (fatty) change, multifocal random degeneration and necrosis, and centrolobular degeneration and necrosis. These lesions were observed in 90-100% of the exposed animals and were absent in the air-only controls. There was significant individual animal variation in susceptibility to both HCFC-123 and halothane, resulting in a spectrum of histologic lesions and clinical chemistry values within each exposure group. Alanine aminotransferase, aspartate aminotransferase, and ICDH were the most significant predictors of hepatocellular damage. Similarities in the response between halothane and HCFC-123 in this guinea pig model suggests that humans susceptible to halothane-induced hepatitis may be susceptible to HCFC-123 by a common mechanism of toxicity.

A reduction in serum enzymes has been already observed by administering ursodeoxycholic acid to patients with chronic active hepatitis. The aim of this study was to assess whether the liver histological activity of inflammation was modified by a 12-month treatment with ursodeoxycholic acid. Thirty-six patients with chronic active hepatitis, fulfilling the inclusion criteria, were admitted to the trial. Patients were randomly allocated to receive double blind either 600 mg/day of ursodeoxycholic acid (Group A: 18 patients) or placebo (Group B: 18 patients). Clinical and biochemical follow-up was performed at acid (Group A: 18 patients) or placebo (Group B: 18 patients). Clinical and biochemical follow-up was performed at 3-month intervals. A percutaneous liver biopsy was performed before and after 1 year of treatment. Histological hepatitis activity was assessed using Knodell's numerical scoring system, while biliary damage was evaluated by an appropriate scoring system. Sixteen and 12 patients in Groups A and B, respectively, completed the clinical and biochemical follow-up. Although a reduction in serum enzymes was found in both groups, multifactorial covariance analysis showed that the reductions in alanine aminotransferase, aspartate aminotransferase and gamma glutamyl transpeptidase were significantly higher in Group A than in Group B. Biochemical remission was not observed in either group. Histological analysis showed a dichotomy between the results from the hepatitis and the biliary components of the disease process. No differences were found in the two groups before or after treatment in histological activity index, which measures the "hepatitic" component. Nor were there any significant differences in baseline values.(ABSTRACT TRUNCATED AT 250 WORDS)
