Sirolimus plus sorafenib in treating HCC recurrence after liver transplantation: a case report.

A case of hepatocellular carcinoma (HCC) with pulmonary recurrence after liver transplantation for HCC is presented in this report. The patient showed disease progression on sorafenib therapy demonstrated by computed tomography scans as well as serial serum α-fetoprotein (AFP) elevation. After his immunosuppression therapy was successfully transitioned to sirolimus and a continuation of sorafenib, he achieved partial remission based on RECIST criteria and normalization of AFP. Mammalian target of rapamycin inhibitors including sirolimus alone or in conjunction with sorafenib may be useful in the treatment of post transplant HCC.

Transjugular intrahepatic portosystemic shunt for variceal hemorrhage due to recurrent of hereditary hemorrhagic telangiectasia in a liver transplant.

Hepatic involvement in hereditary hemorrhagic telangiectasia (HHT) consists of vascular malformations associated with arteriovenous (AV), arterioportal, and/or portovenous shunting. Most patients with HHT have liver involvement. Symptoms, although rare, consist of cardiac failure, pulmonary hypertension, portal hypertension, portosystemic encephalopathy, cholangitis, and atypical cirrhosis. Reported treatments for symptomatic AV malformations have been associated with substantial morbidity and mortality. This report describes a case of hepatic HHT that required liver transplantation after hepatic artery embolization. Recurrent vascular malformations developed in the transplant, resulting in portal hypertension and life-threatening variceal hemorrhage that was controlled with transjugular intrahepatic portosystemic shunt creation.

Severe, late-onset graft-versus-host disease in a liver transplant recipient documented by chimerism analysis.

A 52-year-old liver transplant recipient presented 8 months after transplantation with oral thrush, then 3 days later with oral ulcers and a diffuse rash, and 5 days later with an acutely reduced white blood cell count, rash, fever, and diarrhea. Bone marrow biopsy revealed severe aplasia. Although graft-versus-host disease (GVHD) was considered, the late onset of these symptoms was felt to render this etiology unlikely because GVHD usually occurs 2 to 6 weeks after transplantation. All potentially myelosuppressive medications were discontinued, and the patient was treated with high doses of hematopoietic growth factors. Because his symptoms continued, chimerism analysis was performed, which indicated that 96% of the peripheral blood mononuclear cells were of liver-donor origin. Ultimately, the patient underwent an allogeneic peripheral blood hematopoietic progenitor cell transplant from a human leukocyte antigen-identical brother, but he died 5 days after transplantation of overwhelming Candida kruseii infection. To our knowledge, this is the first chimerism-analysis-documented case of severe acute GVHD presenting so late after liver transplantation. It is of note that the patient had no known risks for GVHD in that he was relatively young and shared only one major human leukocyte antigen with his donor. Consideration should be given to GVHD as a cause of bone marrow aplasia at any time after organ transplantation. Storage of cell pellets from all transplant recipients and donors is highly recommended to facilitate the diagnostic evaluation.

Histologic changes resembling acute rejection in a liver transplant patient treated with terbinafine.

We present a case of histologic changes resembling acute cellular rejection in a liver transplant patient treated with terbinafine. Approximately 5 years after orthotopic liver transplantation, a 51-year-old Hispanic man developed elevated liver enzyme levels. A biopsy sample was interpreted as acute cellular rejection, and the patient was treated with increased immunosuppression. Review of medications showed that the patient had been started on terbinafine approximately 4 weeks earlier for onychomycosis, and it was discontinued. A follow-up visit 2 weeks later revealed progressive jaundice, malaise, and nausea, and evaluation of a second liver biopsy sample revealed marked centrilobular cholestasis and severe bile duct damage, consistent with terbinafine hepatotoxicity. Although these histologic changes have been described in treated patients with both normal and abnormal livers, the potential for confusion with acute rejection in patients with hepatic transplantation has not previously been reported.

Evaluation of a model to predict poor survival in patients undergoing elective TIPS procedures.

PURPOSE: To validate a previously published model to predict the probability of patient death within 3 months after an elective transjugular intrahepatic portosystemic shunt (TIPS) procedure. The model is implemented with use of a nomogram or a formula. MATERIALS AND METHODS: Patients who underwent an elective TIPS procedure between May 1, 1999, and May 1, 2001, were selected. Patients who underwent emergency TIPS creation and patients with serum creatinine levels greater than 3.0 mg/dL were excluded. A total of 72 patients met the inclusion criteria. The patients were divided into two groups: group A (ethanol-induced cirrhosis; n = 23) and group B (non-ethanol-induced cirrhosis; n = 49). The model was applied and the predicted probability of death was compared to actual patient survival. A high risk score (R > or = 1.8) is associated with a high risk of death within 3 months after TIPS creation. Survival curves were estimated with use of Kaplan-Meier product limit estimates and were compared with use of the log-rank test. The model's accuracy was evaluated with use of the c-statistic. P values lower than.05 indicated statistical significance. RESULTS: The technical success rate was 98.7%. The 3-month survival rate for the whole group was 79.7%. The predicted mortality rate was higher than the observed mortality rate. The c-statistic was 0.65 for the formula and 0.66 for the nomogram. Patients with a risk score of at least 1.8 had a 3-month survival rate of 54.6% and patients with a risk score lower than 1.8 had a 3-month survival rate of 84.9% (P =.037). CONCLUSION: These results confirm that, after an elective TIPS procedure, patients with risk scores of at least 1.8 have a significantly lower 3-month survival rate than patients with risk scores lower than 1.8.
