RESUMO

Cytomegalovirus (CMV) is the most common viral pathogen that negatively affects the outcome of liver transplantation. CMV causes febrile illness often accompanied by bone marrow suppression, and in some cases it invades tissues, including the transplanted allograft. In addition, CMV has been significantly associated with an increased predisposition to allograft rejection, accelerated hepatitis C recurrence, and other opportunistic infections, as well as reduced overall patient and allograft survivals. We carried out a study on a Spanish adult liver transplant recipient who rapidly presented anemia and was diagnosed as having Coomb negative (nonimmune) hemolytic anemia, gastric ulcer, pneumonitis, and cholangitis associated with a CMV infection.

RESUMO

BACKGROUND: End-stage cirrhosis due to hepatitis C virus (HCV) is one of the most common indications for orthotopic liver transplantation (OLT). Recurrence is universal and more aggressive than before OLT. The aim of this study was to evaluate the efficacy and tolerability of antiviral therapy in recurrent HCV after OLT. Therapy was started even with mild fibrosis (F < 2) and extended until 72 weeks, if it was possible. METHODS: Between November 2001 and December 2010, 279 OLTs were performed in 262 patients in our hospital; 81 (31%) for HCV-related cirrhosis. Nineteen patients were excluded because they died in the first 6 months. We treated 28 of 62 HVC patients. RESULTS: Twenty-eight patients met the indication for antiviral therapy: 21 male (75%) and 7 female (25%), with a mean age of 56 years (range, 40 to 68 years). All the patients had histologically proven recurrence liver disease: F1, 19 patients (68%); F2, 4 patients (14%), and F3, 45 patients (18%). The mean time to recurrence was 23 months, with a range of 3 to 90 months. Adverse effects (leukopenia in 82% and anemia in 79%) were treated with granulocyte colony-stimulating factor (GCSF) and erythropoietin (EPO), and dose reduction. Four patients (14%) were withdrawn from the treatment because of adverse effects. Nineteen patients achieved early virologic response (68%), and the sustained virologic response was 54% (15 of 28 patients). Five patients died (18%). CONCLUSION: Improving sustained virologic response in HCV liver transplant patients is a key goal. Antiviral therapy is safe and effective treating HCV recurrence after OLT. Starting this therapy in an early stage of hepatitis C recurrence, extending antiviral therapy (72 weeks), and avoiding dose reduction of antiviral drugs could help to achieve higher rates of sustained virological response.

RESUMO

BACKGROUND: The mammalian target of rapamycin (mTOR) inhibitors are new immunosuppressive drugs for organ transplantation. They are interesting for liver transplantation because of their absence of nephrotoxicity and potential antitumor effects, because calcineurin inhibitors (CNI) are associated with renal dysfunction post-CNI and tumors. We sought to analyze the indications, safety, and efficacy of mTOR among liver transplant patients at our center. METHODS: We retrospectively identified patients who were treated with mTOR for their indications for liver transplantation, type of immunosuppressive therapy, acute rejection episodes, and evolution of kidney function. RESULTS: We identified 43 (19.02%) patients treated with mTOR including 35 (81.4%) males and 8 (18.6%) females of overall average age of 56.7 (range, 44-68). In 30% of patients, the drug was introduced for kidney failure, and in 23% for actual or a high risk of hepatocellular carcinoma (HCC) recurrence. The average time to introduction of the mTOR was 6.4 months (range, 1-46). The final immunosuppressive regimen was mTOR alone (73%), or mTOR plus CNI (23%), or mTOR plus mycophenolate mofetil (4%). The average values of creatinine and urea were lower after conversion to mTOR (P < .05) with a 6.9% incidence of acute rejection episodes. CONCLUSION: The mTOR immunosuppressive drugs are safe for liver transplant patients, effectively controlling renal dysfunction. They can be used in other indications, such as neurotoxicity, de novo tumors, and high risk of HCC recurrence. More studies are needed to clarify their long-term effectiveness.

RESUMO

UNLABELLED: It has been suggested that in the cellular rejection of hepatic graft, the lesion provoked by cytotoxic T-lymphocytes might be mediated by the Fas antigen/Fas ligand system, producing cell death by apoptosis. AIM: To determine whether soluble Fas (sFas) is increased during treatment and to evaluate response to treatment. MATERIAL AND METHODS: Fourteen patients with orthotopic liver transplantation who presented an episode of acute cellular rejection were studied. Serum levels of sFas were detected by enzyme-immunoanalysis at diagnosis and again 5 days after treatment was completed. As control groups, sFas was analyzed in 12 patients with liver transplantation without rejection and in 10 healthy subjects. RESULTS: sFas levels were found to be significantly higher in patients with rejection than in those without rejection and in healthy subjects (24.2 +/- 39.1 vs. 2.8 +/- 4.0 vs. 0.6 +/- 1.5 UI/ml; p = 0.03). In patients with acute cellular rejection, immunosuppressive treatment significantly decreased sFas levels compared with basal values (24.2 +/- 39.1 vs. 9.9 +/- 30.2 UI/ml; p = 0.005). A clear correlation between the serum levels of sFas, glutamate oxaloacetate transaminase (GOT), glutamate-pyruvate transaminase/glutamic-pyruvic transaminase (GPT) and gamma-glutamyl transferase (GGT). CONCLUSIONS: a) The increase of sFas during rejection and the decrease in patients with a good evolution suggests that the Fas system may play an important role in the hepatocyte lesion produced by an apoptosis mechanism in these patients. b) Monitoring sFas could be useful in diagnosing rejection and in evaluating response to treatment.

RESUMO

Intestinal bacterial overgrowth (IBD) is very frequent in patients with chronic hepatopathies. Causes of IBO, although not entirely known, principally are: the hepatopathy, the alcoholism and the alterations produced by these two factors, such as achylia (and above all hypochlorhydria), decrease in the secretion of IgA, and malnutrition. On the other hand, the IBO increases the severity of the hepatopathy and frequently produces a bacterial peritonitis. All these data suggest that the IBO play an important role increasing the hepatopathy severity and consequently is a factor to bear in mind.
