Pancreatitis-associated protein I (PAP I) is a secretory protein first described as an acute phase reactant during acute pancreatitis. Recently, induction of the PAP I gene was also described in liver during hepatocarcinogenesis. To investigate the molecular mechanisms of this induction, we used constructs carrying progressive deletions of the PAP I promoter fused to the CAT gene. We showed that the silencer conferring tissue specificity on the PAP I gene was inactive in hepatoma cells. Then, in an vitro transcription system, we compared the transcription capacity of nuclear extracts from normal liver and HepG2 cells on constructs containing the silencer. The results confirmed that a trans-acting factor interacting with the PAP I silencer was present in liver cells and absent from hepatoma cells. On the other hand, immunohistochemistry showed that PAP I was expressed in a limited number of transformed hepatocytes. It was concluded that expression of PAP I in hepatocarcinoma occurred through inactivation of its silencer element and was not concomitant in all malignant cells. On that basis, we assayed PAP I in serum from patients with chronic hepatitis, liver cirrhosis or hepatocarcinoma. PAP I levels were normal in chronic active or persistent hepatitis, significantly higher in cirrhosis and strongly elevated in hepatocarcinoma. Because those clinical entities often develop in that sequence, serum PAP I appeared as a potential marker of hepatocarcinoma development.

Chronic hepatitis B is a widespread viral illness with the serious sequelae of cirrhosis and hepatocellular carcinoma. Current therapy with interferon is not universally efficacious, and this has led to the evaluation of other antiviral agents. A recent Phase II trial of the nucleoside analogue, fluoroiodoarabinofuranosyluracil (fialuridine, FIAU) was halted because of the sudden development of severe multisystem toxicity characterized by hepatic failure, lactic acidosis, and pancreatitis, which resulted in the deaths of five patients. We systematically evaluated pre- and post-therapy biopsy, explant, and autopsy specimens from the 15 patients involved in this trial to define the hepatic changes of fialuridine toxicity and to determine whether the degree of pre-existing hepatitis contributed to the severity of toxicity. Severe hepatotoxicity from fialuridine was characterized by hepatomegaly with diffuse, predominantly microvesicular steatosis, hepatocellular glycogen depletion, marked bile ductular proliferation, and cholestasis. Ultrastructural examination revealed intracytoplasmic lipid droplets and marked mitochondrial injury. Patients in whom severe toxicity did not develop mainly showed changes caused by the underlying chronic hepatitis B alone. There was a subtle increase in the amount of microvesicular steatosis in two of six patients with mild or no symptoms of toxicity. The microscopic and ultrastructural pattern of injury and systemic symptoms in patients with fialuridine toxicity are consistent with severe mitochondrial and metabolic derangements. Similar hepatic pathologic findings have been reported rarely for other antiviral nucleoside analogues, which suggests that the mechanisms of toxicity might be related.

A case of progressive encephalomyelitis with rigidity (PEWR) associated with hepatitis C virus (HCV) is reported. A 58 year-old woman presented with a clinical picture of progressive quadriparesis, sensory loss, sphincter dysfunction, painful muscle spasms in the upper and lower limbs and continuous muscle unit activity in electromyography. She developed hepatitis, pancreatitis and HCV-RNA was detected in the plasma by reverse transcription-polymerase chain reaction (RT-PCR). Postmortem histopathological examination showed encephalomyelitis with perivascular lymphocyte cuffing, infiltration and neuronal loss mainly affecting the brainstem and cervical spinal cord. The RT-PCR analysis of the postmortem brain, brainstem, liver, pancreas, plasma and CSF samples revealed the presence of HCV genome in all specimens except CSF. Clinical features, postmortem histopathology and PCR results and the possible etiopathogenesis of PEWR are briefly discussed.

Patients with advanced-stage unresectable hepatocellular carcinoma (HCC) were treated with intrahepatic arterial doxorubicin 30 mg/m2 plus escalating doses of cisplatin up to 100 mg/m2 in conjunction with rapid bolus injection of Spherex (degradable starch microspheres; Kabi Pharmacia, Lund, Sweden) into the hepatic artery, until slowing or reversal of blood flow. Treatments were repeated every 4 to 6 weeks until progression, or were continued indefinitely if there was disease stability or response. Thirty-five evaluable patients have so far been accrued to the study. Objective tumor responses have occurred in 22 patients (63%), of whom 20 had partial responses and two had complete responses. Four of the patients had reversal of tumor-induced portal vein thrombus. Toxicities included death, one patient (and a death of uncertain cause in an additional patient); hepatitis, two patients; pancreatitis, one patient; dyspnea/hypotension, two patients; and hepatic artery nontransient thrombosis in four patients. Six patients have survived 2 years and an additional 10 patients have survived 1 year. The addition of Spherex to intrahepatic arterial chemotherapy for advanced-stage HCC appears to be relatively safe and is well tolerated even in patients with portal vein thrombosis, which represent the majority of patients with advanced-stage HCC.

Herpesvirus 6 (HHV-6) is a ubiquitous virus known to cause febrile syndromes and exanthema subitum in children. Less commonly, and particularly in organ transplant recipients, it may result in hepatitis, bone marrow suppression, interstitial pneunonitis, and meningoencephalitis. This report expands the spectrum of clinical disease associated with HHV-6 by documenting viral infection in a 44-year-old heart transplant recipient presenting with gastroduodenitis, pancreatitis, and hepatitis. On histopathologic examination, the gastric, duodenal, and bile ductular epithelium showed a multinucleate giant cell transformation similar to the cytopathic effect caused by the virus in human T-lymphocytes infected in vitro. Electron microscopy showed herpes particles with a thick tegument layer in the duodenum. Polymerase chain reaction amplified HHV-6 variant A sequences from multiple sites. Serology confirmed the presence of an acute HHV-6 infection. Thus, HHV-6 variant A can cause gastroduodenitis and pancreatitis in immunosuppressed individuals. Multinucleate giant cells and enveloped virions with a prominent tegument can be used as morphologic criteria to raise the possibility of HHV-6 infection in human biopsy tissue.

We report two boys with juvenile dermatomyositis (JDM) complicated by pancreatitis. One also had hepatitis and probably mild bowel vasculitis, while the other had catastrophic bowel vasculitis with multiple perforations. Both were on corticosteroids, but had features of active vasculitis. The former improved with high-dose i.v. pulsed methylprednisolone, while the latter improved only after immunosuppression with i.v. methylprednisolone, cyclophosphamide and plasmapheresis. Although bowel vasculitis is a known complication of severe JDM, pancreatitis and hepatitis are extremely rare. We have found in a literature search only three other reports of pancreatitis complicating JDM. We wish to alert physicians that pancreatitis may develop in JDM. It should be considered as a differential diagnosis in the child with active disease who develops abdominal pain. Control of vasculitis with adequate immunosuppression, as well as general supportive measures, may be valuable in the treatment of pancreatitis in JDM.

Complex investigation of the immune state of 123 patients with chronic inflammatory diseases of biliary system (CDBS) was conducted. The reduce of T-lymphocytes quantity and functional activity, their subpopulations, level of complement, the blood serum lysozyme, the increase of B-lymphocytes content, serumal IgG, IgM, circulating immune complexes (CIC), the antibodies titer to the gallbladder tissue, liver, pancreas, and level of the lymphocytes sensibilization to these antigens in the acute period of the disease. Presence of calculi in gallbladder, coexistence of cholecystitis with reactive hepatitis or pancreatitis caused more significant changes in immune system.

Necrolytic migratory erythema is characterized by waves of irregular erythema in which a central bulla develops, and subsequently erodes and becomes crusted. It usually occurs in patients with an alpha-islet cell tumor of the pancreas. However, necrolytic migratory erythema has also been observed in patients without an associated glucagonoma. We describe a woman with iatrogenic necrolytic migratory erythema. She received intravenous glucagon for hypoglycemia associated with an insulin-like growth factor II-secreting hemangiopericytoma. After chemotherapy, she developed necrolytic migratory erythema. The characteristics of the previously reported patients with nonglucagonoma-associated necrolytic migratory erythema are reviewed. In patients with nonglucagonoma-associated necrolytic migratory erythema, the dermatosis-related conditions most commonly observed were celiac disease or malabsorption, cirrhosis, malignancy, and pancreatitis; less common conditions included hepatitis, inflammatory bowel disease, heroin abuse, and odontogenic abscess. Although the pathogenesis of necrolytic migratory erythema remains unknown, hyperglucagonemia appears to have had a causative role in the development of this dermatosis in our patient. Patients who develop necrolytic migratory erythema should be evaluated for the presence of a glucagonoma; if a glucagonoma is ruled out, evaluation for other conditions known to occur with necrolytic migratory erythema, such as liver disease, malabsorptive disorders, and nonislet-cell tumors is warranted.
