Current treatment strategies of variceal bleeding (VB) include banding and sclerotherapy. However, up to 10% of bleeding events remain refractory to standard therapy with high mortality. With this ...study, we aimed to evaluate the implantation of self-expanding metal stents (SEMS) for the management of therapy-refractory variceal bleeding.
Eight cirrhotic patients who presented to our unit with a total of 9 refractory bleeding events were treated by SEMS placement.
Stenting resulted in immediate hemostasis in all cases without recurrent bleeding with SEMS in situ. After stabilization, 1 patient was treated by transjugular intrahepatic portosystemic shunt (TIPS) and after the second bleeding episode by TIPS dilation. One patient underwent orthotopic liver transplantation (OLT). The remaining patients were treated with standard drug regimens to reduce portal pressure. The SEMS were removed after a median of 11 days. No acute hemorrhage was noted on stent retrieval. While no early rebleeding occurred in the patients after TIPS implant, TIPS dilation or OLT, 3 out of 5 patients on conservative treatment experienced recurrence of VB within 9 days after SEMS removal.
SEMS placement sufficiently stops hemorrhage in refractory VB. Due to the high rebleeding rate after conservative treatment alone following SEMS removal, this procedure may be utilized as a mere bridging method. Additional interventional and/or surgical methods to effectively reduce portal pressure (i.e. TIPS, OLT) should be considered. Further studies to evaluate the optimum treatment algorithm of refractory esophageal VB are warranted.
Bleeding from esophageal varices is a major cause of mortality in patients with advanced liver disease. Although standard treatment and secondary prophylaxis are effective, in some patients sustained ...hemostasis cannot be achieved. We report the case of a woman with alcoholic liver disease in whom pharmacological, endoscopic, and intravascular therapies failed to control variceal bleeding. Only a combination of (repeated) band ligation, insertion of a self-expanding metal stent, TIPS implantation and redilatation, transjugular variceal embolization, and finally implantation of a portocaval shunt proved to be successful. We discuss the stepwise approach to this situation and the challenges encountered in the process.
Hepatocellular carcinoma (HCC) is one of the leading causes of death in cirrhotic patients worldwide. The detection rate for early stage HCC remains low despite screening programs. Thus, the majority ...of HCC cases are detected at advanced tumor stages with limited treatment options. To facilitate earlier diagnosis, this study aims to validate the added benefit of the combination of AFP, the novel biomarkers AFP-L3, DCP, and an associated novel diagnostic algorithm called GALAD.
Between 2007 and 2008 and from 2010 to 2012, 285 patients newly diagnosed with HCC and 402 control patients suffering from chronic liver disease were enrolled. AFP, AFP-L3, and DCP were measured using the µTASWako i30 automated immunoanalyzer. The diagnostic performance of biomarkers was measured as single parameters and in a logistic regression model. Furthermore, a diagnostic algorithm (GALAD) based on gender, age, and the biomarkers mentioned above was validated.
AFP, AFP-L3, and DCP showed comparable sensitivities and specifities for HCC detection. The combination of all biomarkers had the highest sensitivity with decreased specificity. In contrast, utilization of the biomarker-based GALAD score resulted in a superior specificity of 93.3 % and sensitivity of 85.6 %. In the scenario of BCLC 0/A stage HCC, the GALAD algorithm provided the highest overall AUROC with 0.9242, which was superior to any other marker combination.
We could demonstrate in our cohort the superior detection of early stage HCC with the combined use of the respective biomarkers and in particular GALAD even in AFP-negative tumors.
Among patients after renal transplantation (NTx), hepatitis C virus (HCV) infection is a risk factor for graft loss and patient death caused by hepatic decompensation. Also, HCV has been implicated ...in the pathogenesis of glomerular diseases in native and transplanted kidneys. Therefore, the aim of this retrospective cohort study was to determine the effects of the widely used calcineurin inhibitors (CNI) cyclosporine A (CsA) and tacrolimus (Tac) on hepatitis C virus replication, inflammatory activity, development of liver fibrosis, and long-term renal graft function.
A cohort of 71 patients with HCV infection after kidney transplantation under immunosuppression with either CsA or Tac were analyzed for viral kinetics and serum transaminases. In addition, presence of liver fibrosis was detected by non-invasive measurements using the FibroScan. Graft function was determined biochemically. Patients with interferon therapy prior to transplantation were excluded from the study in order to avoid any impact of the antiviral therapy on outcomes.
In the early period after transplantation, hepatitis C viral load was lower in patients treated with Tac as compared to CsA. This effect became negligible 3 months after transplantation. However, hepatic inflammatory activity was reduced in the CsA-treated group. Extent of liver fibrosis was similar in both groups of HCV-infected patients as well as in a control group of non-HCV-infected patients after renal transplantation (NTx), respectively. Renal function and glomerular filtration rate, as calculated by the modification of diet in renal disease (MDRD) formula, were significantly better in patients treated with Tac.
During long-term immunosuppression, the CNIs cyclosporine A versus tacrolimus showed no significant differences in HCV-infected patients after renal transplantation with respect to viral replication and development of liver fibrosis. However, function of the renal graft is significantly better preserved in patients receiving tacrolimus.
Introduction
Patients (pts) with locally advanced (LAPC) or metastatic pancreatic ductal adenocarcinoma (mPDAC) have a dismal prognosis. Recently, new combination chemotherapies such as FOLFIRINOX ...and nab-paclitaxel/gemcitabine have demonstrated superiority over gemcitabine monotherapy. However, a substantial proportion of pts cannot tolerate these intensive front-line protocols. Moreover, the long-term superiority of multiagent protocols over less intensive strategies remains to be shown. To provide a benchmark for future studies, we analyzed the outcome of patients with LAPC or mPDAC treated at the West German Cancer Center before the FOLFIRINOX/nab-paclitaxel + gemcitabine era.
Methods
This retrospective analysis included 201 consecutive pts with LAPC and mPDAC treated between 2007 and 2011. Efficacy parameters were correlated with type of chemotherapy, number of treatment lines and clinicopathological parameters.
Results
Gemcitabine monotherapy was given as first-line therapy in 51.1%, whereas 48.9% received combination chemotherapies such as gemcitabine/oxaliplatin or FOLFOX. Patients received a median of two lines of treatment, with 54.8% receiving second-line and 37.9% receiving third- and further-line therapies. There was no significant difference between gemcitabine monotherapy and combination therapies. Despite moderate activity of first-line treatment, median overall survival for LAPC was 11.3 months and 8.7 months for mPDAC. Multivariate analysis identified age and number of treatment lines as prognostic markers.
Conclusion
The long-term outcome of unselected pts with LAPC and mPDAC treated before the introduction of aggressive multiagent chemotherapy protocols compares favorably with the results of contemporary benchmark trials. This suggests a multifactorial benefit from interdisciplinary care provided over sequential treatment lines at high volume expert centers.
