Hepatic graft-versus-host disease (GVHD) generally presents as cholestatic jaundice, and increased serum alkaline phosphatase (ALP) is followed by hyperbilirubinemia and clinical jaundice. Currently accepted standards for evaluating the clinical severity of GVHD are based not on serum aminotransferase levels but on the serum bilirubin level. We describe a 17-year-old Japanese female who had increased aminotransferases without cholestasis on day 23 after allogeneic peripheral blood stem cell transplantation (allo-PBSCT). Liver biopsy revealed lymphocytic infiltration of the portal tracts and pericentral necrosis of the lobuli. The limiting plates were not clearly defined due to cellular infiltrates. There was periductal lymphocytic infiltration and vacuolization of the biliary epithelial cells with exocytosis, compatible with GVHD of cholangiohepatitic type. These findings indicate that acute hepatic GVHD may present as acute hepatitis and this should be included in the differential diagnosis for patients with increased aminotransferases after allogeneic stem cell transplantation.

Fifteen male patients with acute hepatitis C aged 16-44 years were treated with neovir, an interferon inducer, administered intramuscularly in a daily dose of 250 mg 2-3 times a week for 3 months. By the end of this therapy the RNA of hepatitis C virus could still be detected in 84.6% of the patients, the characteristics of ALT, AST and alkaline phosphatase exceeded the norm more than twofold. The results of neovir therapy are regarded as ineffective.

To assess the possible influence of human immunodeficiency virus type 1 (HIV-1) infection on the clinical course of acute hepatitis A virus (HAV) infection, 15 HIV-1-infected homosexual men and 15 non-HIV-infected age-matched subjects were compared. HAV load was higher in HIV-1-infected than in non-HIV-infected patients (P<.001). Duration of viremia in HIV-1-infected patients (median, 53 days) was significantly (P<.05) longer than in non-HIV-infected patients (median, 22 days). HIV-1-infected patients had lower elevations in alanine aminotransferase levels than did non-HIV-infected patients (P<.01) but had higher elevations in alkaline phosphatase levels than did non-HIV-infected patients (P<.001). Some HIV-1-infected patients still had HAV viremia when clinical symptoms had disappeared and alanine aminotransferase levels had returned to normal (60-90 days after the onset of symptoms). HIV-1 infection was associated with prolongation of HAV viremia, which might cause a long-lasting outbreak of HAV infection in HIV-1-infected homosexual men.

New antiviral drug "Nikavir" was clinically tested in acute hepatitis B (AHB). A total of 60 AHB patients were followed up; 30 patients were in the main group and 30 persons were in the control group. The treatment with Nikavir of AHB patients was shown to ensure a favorable clinical disease course and it was accompanied by a quicker rate in reduction of the activity of serum enzymes AIAT, AcAT, alkaline phosphatase and of gamma-glutamil-transpeptidase; besides, it was accompanied by an early elimination of such serum markers of AHB like HBeAg, HbsAg and HBV DNA. Wikavir can be used in the treatment of patients with mild and moderate forms of AHB.

Hepatic graft-versus-host disease (GVHD) post allogeneic hematopoietic stem cell transplantation generally presents as cholestatic jaundice and increased serum alkaline phosphatase (ALK-P). Currently accepted standards for evaluating the clinical severity of hepatic GVHD are not based on serum aminotransferase levels but on the serum bilirubin levels. We describe a 25-year-old female who initially had no liver damage at all after an allogeneic peripheral blood stem cell transplantation (allo-PBSCT) from her HLA-indentical sister. Markedly elevated aminotransferases, without hyperbilirubinemia, however, developed 7 and 9 weeks after the first and second donor lymphocyte infusion (DLI), respectively. Liver biopsies performed in both events revealed lymphocytic infiltration of the portal tracts and pericentral necrosis of the lobuli. There was also a picture of periductal lymphocytic infiltration and vacuolization of the biliary epithelial cells, which was compatible with the diagnosis of GVHD of cholangiohepatitic type. These findings indicate that hepatic GVHD may present as acute hepatitis and should be included in the differential diagnosis for patients with increased aminotransferases after DLI.

To evaluate indications for living-donor liver transplantation (LDLT), we examined 25 consecutive patients with acute hepatic failure admitted to the Department of Medicine III, Kyushu University Hospital between November 2001 and July 2004. These cases were diagnosed as fluminant hepatitis (n=13), severe-type acute hepatitis (n=11), or late-onset hepatic failure (n=1). Nine patients (36%) improved with conservative treatment (conservative treatment group), and the other 16 patients (64%) needed LDLT (LDLT indicated group). In the LDLT indicated group, 11 patients received LDLT, and 4 died because of lack of LDLT donors (n=3), or renal failure (n=1). The LDLT survival rate was 82% (9/11); two patients died due to hepatic infarction and brain edema, respectively. It is very important to predict whether a patient with acute hepatic failure belongs to the conservative treatment group or the LDLT indicated group on admission. Therefore, we analyzed variables that could influence prognosis, including, parameters of hepatic function and platelet counts on admission, and relative hepatic volume (%), which represents the ratio of hepatic volume measured by CT relative to standard hepatic volume calculated with body surface area. Univariate logistic analysis showed that relative hepatic volume, gammaglutamyl transpeptidase (gamma-GTP), alkaline phosphatase (ALP), and the ratio of direct bilirubin to total bilirubin (DB/TB) were significant predictors of survival (p < 0.05). Using these factors plus prothrombin time (PT) and total cholesterol, both of which were relatively significant predictors of survival (p < 0.2), we proposed a model for predicting the probability of survival by the stepwise method. Consequently, we proposed a model using four parameters: ALP, GGTP, PT, and relative hepatic volume (Volume) as shown below: p(%) = 1/(1+exp (-(-36.2375 + ALP x 0.0251 + gamma-GTP x 0.0102 + PT x 0.2558 + Volume 21.2158))) x 100. This model showed a significant correlation between prediction and consequence of survival (r2 = 0.7388, p = 0.0003). In conclusion, LDLT is an effective treatment for acute hepatic failure. The results of this study suggested that our model can adequately predict prognosis in the early phase of acute hepatic failure.

Saw palmetto is a frequently used botanical agent in benign prostatic enlargement (BPH). Although it has been reported to cause cholestatic hepatitis and many medical conditions, Saw palmetto has not been implicated in acute pancreatitis. We report a case of a probable Saw palmetto induced acute hepatitis and pancreatitis. A 55-year-old reformed alcoholic, sober for greater than 15 years, presented with severe non-radiating epigastric pain associated with nausea and vomiting. His only significant comorbidity is BPH for which he intermittently took Saw palmetto for about four years. Physical examination revealed normal vital signs, tender epigastrium without guarding or rebound tenderness. Cullen and Gray Turner signs were negative. Complete blood count and basic metabolic profile were normal. Additional laboratory values include a serum amylase: 2,152 mmol/L, lipase: 39,346 mmol/L, serum triglyceride: 38 mmol/L, AST: 1265, ALT: 1232 and alkaline phosphatase was 185. Abdominal ultrasound and magnetic resonance cholangiography revealed sludge without stones. A hepatic indole diacetic acid scan was negative. Patient responded clinically and biochemically to withdrawal of Saw palmetto. Two similar episodes of improvements followed by recurrence were noted with discontinuations and reinstitution of Saw Palmetto. Simultaneous and sustained response of hepatitis and pancreatitis to Saw palmetto abstinence with reoccurrence on reinstitution strongly favors drug effect. "Natural" medicinal preparations are therefore not necessarily safe and the importance of detailed medication history (including "supplements") cannot be over emphasized.

Murine cytomegalovirus (MCMV) has provided useful models for acute, chronic and latent CMV infection because of its similarities in structure and biology with human CMV. We report the induction of acute MCMV hepatitis with different bacterial artificial chromosome (BAC)-cloned virus constructs [MCMV-SEAP which includes the gene for secreted alkaline phosphatase (SEAP) under Rous sarcoma virus (RSV)-promoter control, MCMV-GFP which includes the gene for enhanced green fluorescent protein (eGFP) under HCMV-ie promoter control, MCMV-HBs includes the gene for hepatitis B surface antigen (HBsAg) under simian virus (SV)40-promoter control and the DeltaMC95.21 virus in which the m152 gene was deleted and substituted by the reporter gene lacZ] in order to elucidate the histopathological changes together with different reporter-gene products in the liver tissue and the effect of the deletion of a certain gene. All the virus constructs induced a similar mild acute hepatitis which had its climax from days 3 to 5 post-infection in immunocompetent mice. In situ, the reporter-gene products beta-galactosidase and secreted alkaline phosphatase could be visualized in relation to the inflammatory changes. The composition of the invading cell populations did not change even in the absence of the m152 gene. Additionally discrete inflammatory changes were seen in kidney and serosa while the other organs were not involved. This model helps us understand the immunological and histopathological mechanisms of the CMV-induced hepatitis, which plays an important role especially in the immunocompromised patient. The morphological changes can be analysed while the respective reporter gene product is expressed by the virus construct.

We report a case of acute hepatotoxicity in a 42-year-old woman after administration of clindamycin for a dental infection. After 6 d of treatment, she had fatigue, nausea, vomiting, anorexia, pruritus and jaundice. Her laboratory analysis showed alanine aminotransferase (ALT), 1795 IU/L (normal range 0-40); aspartate aminotransferase (AST), 1337 IU/L (normal range 5-34); alkaline phosphatase (ALP), 339 IU/L (normal range 40-150); gamma-glutamyl transpeptidase (GGT), 148 IU/L (normal range 9-64 IU/L); total bilirubin, 4.1 mg/dL; direct bilirubin, 2.9 mg/dL and prothrombin time (PT), 13.5 s, with international normalized ratio (INR), 1.04. She was hospitalized, with immediate drug discontinuation. Her liver biopsy specimen showed mixed-type (both hepatocellular and cholestatic) hepatic injury, compatible with a diagnosis of drug-induced hepatitis. An objective causality assessment using the Naranjo probability scale suggested that clindamycin was the probable cause of the acute hepatitis. In susceptible individuals, clindamycin use may lead to acute mixed-type liver toxicity. Complete recovery may be possible if the drug is discontinued before severe liver injury is established.

Acute hepatitis C in immunocompetent individuals is rarely symptomatic and rarely biopsied. Thus, the histologic descriptions of acute hepatitis C remain limited. The histology of 5 cases of acute hepatitis C in adults were studied by selecting cases from the consult and surgical pathology files of a single institution. The 5 individuals, 3 males and 2 females, had an average age at biopsy of 50+/-17 years. They presented with jaundice and other nonspecific abdominal symptoms. The time interval from clinical presentation to biopsy ranged from 2 to 18 weeks. The average alanine aminotransferase/aspartate aminotransferase/alkaline phosphatase at the time of biopsy was 308/73/85 U/L. The average total bilirubin was 5.2 mg/dL. Each individual had a single liver biopsy. The histologic findings of the 2 cases biopsied in close temporal proximity to the initial clinical presentation showed similar histologic findings of mixed portal infiltrates with lymphocytes and neutrophils along with bile ductular proliferation that raised the possibility of down stream biliary tract disease. The lobules showed canalicular cholestasis and mild to moderate inflammation. In the third and fourth case, obtained 8 weeks after presentation, the biopsies showed mild to moderate portal and lobular lymphocytic inflammation, findings that were also present in the last case, obtained 18 weeks after presentation. In conclusion, early after acute hepatitis C viral infection, biopsies can have a cholestatic pattern whereas later biopsies tend to show mild nonspecific portal and lobular lymphocytic inflammation. Proper histologic diagnosis can be aided by an awareness of the various histologic findings, which vary depending on the time interval from clinical symptoms to biopsy.
