Preoperative Alpha-Fetoprotein and Radiological Total Tumor Diameter as Predictors of Hepatocellular Carcinoma Recurrence After Liver Transplantation.

Background: Liver transplantation is a unique treatment opportunity for patients with chronic liver disease and hepatocellular carcinoma (HCC). Selection of HCC patients for transplantation was revolutionized by Milan-based criteria, but tumor recurrence and shortage of organs are still a major concern. Nowadays, additional preoperative tumor parameters can help to refine the graft allocation process.

Liver Transplant and Active Ulcerative Colitis: A Case Report.

Background: The association between ulcerative colitis (UC) and primary sclerosing cholangitis has been described for several years and can be classified as having a distinct disease phenotype from inflammatory bowel diseases (IBD). The simultaneous occurrence of decompensated liver disease requiring liver transplant and active IBD is a management challenge, considering that these patients may be at increased risk of infections, thromboembolic events, bleeding, and drug hepatotoxicity.

Case Presentation: We describe a case of a 37-year-old patient with UC and sclerosing cholangitis presenting with severe decompensated rectocolitis complicated with thromboembolic phenomena and severe liver dysfunction who underwent liver transplant while using biological therapy to control bowel disease.

Progressive Familial Intrahepatic Cholestasis Type 2 and Recurrence After Liver Transplantation: A Case Report.

Progressive familial intrahepatic cholestasis type 2 (PFIC2) is a rare autosomal recessive disorder caused by mutations in the ABCB11 gene. Clinical manifestations include cholestasis with low γ-glutamyltransferase (GGT), hepatosplenomegaly, and severe pruritus. Liver transplantation is required for individuals with progressive liver disease or failure of the bypass procedure and has been considered curative.

Liver Transplantation After Acute Portal Vein Thrombosis: Case Report.

Background: Portal vein thrombosis is a relatively frequent complication in patients with liver cirrhosis. Its detection and management are essential to avoid worsening portal hypertension or liver function complications. This complication can also negatively impact or even preclude liver transplant.

Non-Alcoholic Fatty Liver Disease-Related Hepatocellular Carcinoma: Immunohistochemical Assessment of Markers of Cancer Cell Metabolism.

Introduction: Hepatocellular carcinoma (HCC) has been associated to non-alcoholic fatty liver disease (NAFLD). We sought to investigate the immunoexpression of several glycolytic metabolism-associated markers in patients with HCC associated to NAFLD and associate these factors to their clinical-pathological characteristics.

Methods: We evaluated 35 HCC specimens from 21 patients diagnosed with non-alcoholic steatohepatitis (NASH) undergoing liver resection (12 patients), liver transplantation (8 patients), or both (1 patient).

Transmission of cryptococcosis by liver transplantation: A case report and review of literature.

Background: Cryptococcosis is a fungal infection caused by the yeast-like encapsulated basidiomycetous fungus of the () species complex. These fungi are ubiquitous in soil and bird droppings, and infection by them is an important global health concern, particularly in immunosuppressed patients, such as organ transplant recipients and those infected by the human immunodeficiency virus. The fungus usually enters the body through the respiratory tract, but extremely rare cases of infection acquired by transplantation of solid organs have been reported.

Hepatocellular carcinoma in non-alcoholic fatty liver disease (NAFLD) - pathological evidence for a predominance of steatohepatitic inflammatory non-proliferative subtype.

Objectives: This study evaluated clinical and pathological aspects of patients with hepatocellular carcinoma (HCC) secondary to non-alcoholic fatty liver disease (NAFLD) and related these factors to immunohistochemical markers representative of the proliferative class.

Methods: We evaluated 35 HCC nodules from 21 patients diagnosed with NAFLD undergoing liver resection (n=12) or liver transplantation (n=8) or both (n=1). Demographic, clinical and biochemical data were compared to histological features and to immunohistochemical reactivity for K19 and Ki-67.

Hypolactasia is associated with insulin resistance in nonalcoholic steatohepatitis.

Aim: To assess lactase gene (LCT)-13910C>T polymorphisms in Brazilian non-alcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) patients in comparison with healthy controls.

Methods: This was a transverse observational clinical study with NAFLD patients who were followed at the Hepatology Outpatient Unit of the Hospital das Clínicas, São Paulo, Brazil. The polymorphism of lactase non-persistence/lactase persistence (LCT-13910C>T) was examined by PCR-restriction fragment length polymorphism technique in 102 liver biopsy-proven NAFLD patients (steatosis in 9 and NASH in 93) and compared to those of 501 unrelated healthy volunteers.
