..Its pathogenesis is poorly understood but this entity appears to be a variant of rejection. Herein, we review recent clinical reports of patients developing PCH...

..Infrequently, hepatitis C (HCV) appears to be the cause of hepatic granulomas. Interferon therapy for HCV has been increasingly associated with the development of sarcoidosis...

..The decision to perform combined transplantation as opposed to an isolated intestinal transplant is based on the presence of hyperbilirubinemia, portal hypertension, and advanced hepatic fibrosis...

..Treatment by optimization of immunosuppression without the use of corticosteroids appears effective. The development of PCH in the setting of recurrent HCV is a negative prognostic factor for patient outcome and allograft failure...

....

..The salient histologic features are elucidated in an attempt to provide the clinician with an understanding of the basic histopathology underlying chronic HCV and HBV...

..The association of significant plasma cell infiltrates in native livers of HCV patients developing PCH suggests that some patients may have a predisposition to developing PCH...

..The proposed algorithm has been applied to quantify the development of progressive fibrosis and its possible regression in liver biopsy specimens from patients with parenteral-induced liver injury undergoing intestinal transplantation...

..Small liver nodules approximately 2 cm are difficult to characterize by radiologic or pathologic examination. Our aim was to identify a molecular signature to diagnose early hepatocellular carcinoma (HCC)...

..17). CONCLUSION: Liver allografts from patients suffering from PNF can have mitochondrial ultrastructural changes on preperfusion biopsies...

..Treatment of rejection or plasma cell hepatitis in this setting should be undertaken in a timely and aggressive fashion to prevent chronic ductopenic rejection...

..This study uses molecular data to identify a subgroup of patients who, despite having hepatocellular carcinoma beyond Milan criteria, have favorable outcomes...

..This report demonstrates that liver transplantation may be an option in selected patients with colorectal cancer liver metastases that have been well treated...

..On follow-up 2 years later, she remains in good health with an undetectable viral load on an efavirenz-based regimen of HAART. To our knowledge, this is the first report of successful liver transplantation following SJS and FHF...

..Results of real microscopic images are provided. The restored image and the original are compared both visually and quantitatively in terms of the estimated entropies measured for the degree of concentrations using vector distributions...

..We hypothesize that pegylated interferon triggered a severe form of immune-mediated hepatitis...

..To our knowledge, this is the earliest reported case of histological recurrence of HCV after LT. It illustrates the importance of older donor and recipient age in the same patient as cofactors for early HCV recurrence and poor outcome...

..We examined the incidence of chronic ductopenic rejection (CR) in patients receiving pegylated interferon alfa-2a and ribavirin (PEG) to treat recurrent HCV...

..Identifying risk factors associated with persistent post- LT thrombocytopenia may provide important information about its pathogenesis...

..Further studies are needed to assess whether decreased IFN-gamma secretion by HCV-specific CD4+ cells may account for accelerated fibrogenesis in these patients...

..Patients experiencing early graft failure due to accelerated forms of HCV should not be denied re-LT with the expectation that a similar disease course will occur after re-LT...

..The clinical manifestations of amiodarone-induced hepatotoxicity and the mechanism of toxicity are also discussed...

..The trend toward a greater initial viral load decrease in patients with LD grafts and the significantly sharper increase suggest that the liver plays a predominant role in both HCV clearance and replication...

..No cause of liver damage other than acute HCV infection was identified. The specific pathways leading to periportal fibrosis in HIV-infected men with newly acquired HCV infection require investigation...

..To date, there has been no report in the literature of symptomatic recurrence of hepatic sarcoidosis following orthotopic liver transplantation...

..09 cell/HPF) and monoinfected patients (0.45 +/- 0.08 cell/HPF). In conclusion, HIV coinfection is associated with fewer portal CD4 cells and increased lobular lymphocyte apoptosis that may impact on the natural history of HCV infection...

..We investigated the molecular alterations of the Ras pathway in HCC and the antineoplastic effects of sorafenib in combination with rapamycin, an inhibitor of mTOR pathway, in experimental models...

..In this model, fibrosis may be a CD8+ T-cell-mediated disease that is attenuated by rIL-10...

..Because studies suggest matrix metalloproteinase-2 (MMP-2) may promote liver injury, we examined whether IL-6 exerted its protective effects via regulation of MMP-2...

..Monitoring of 6 MP metabolite levels in addition to TPMT allele testing is useful to prevent 6 MP toxicity and to help guide therapy...

..The availability of small molecule inhibitors of CXCR4 make this receptor an appealing target for antifibrotic approaches...

..Nodular regenerative hyperplasia (NRH), another cause of noncirrhotic portal hypertension, has also been recently described in HIV patients initially diagnosed as having cryptogenic liver disease...

..This article will discuss obesity-related liver diseases, focusing on pathologic features in liver biopsies from obese patients, obesity-related hepatocellular carcinoma, and the effect of weight loss treatment on histopathology...

..Incorporation of these molecular markers of tumor progression could help resolve the ongoing conundrum of organ allocation for patients with HCC...
