Impact of metabolic syndrome on the outcomes of superficial femoral artery interventions

BackgroundMetabolic syndrome (MetSyn) is an epidemic in the United States and is associated with early onset of atherosclerosis, increased thrombotic events, and increased complications after cardiovascular intervention. MetSyn is found in ∼50% of patients with peripheral vascular disease. However, its impact on peripheral interventions is unknown. The aim of this study is to determine the outcomes of superficial femoral artery (SFA) interventions in patients with and without MetSyn.MethodsA database of patients undergoing endovascular treatment of SFA disease between 1999 and 2009 was retrospectively queried. MetSyn was defined as the presence of ≥3 of the following criteria: blood pressure ≥130 mm Hg/≥85 mm Hg; triglycerides ≥150 mg/dL; high-density lipoprotein ≤50 mg/dL for women and ≤40 mg/dL for men; fasting blood glucose ≥110 mg/dL; or body mass index ≥30 kg/m2. Kaplan-Meier survival analyses were performed to assess time-dependent outcomes. Factor analyses were performed using a Cox proportional hazard model for time-dependent variables.ResultsA total of 1018 limbs in 738 patients (64% male, average age 67 years) underwent endovascular treatment for symptomatic SFA disease with 45% of patients meeting the criteria for MetSyn. MetSyn patients were more likely to be female (P = .001), to present with critical ischemia (rest pain/tissue loss: 55% MetSyn vs 45% non-MetSyn; P = .001), have poorer ambulatory status (P = .001), and have more advanced SFA lesions (TransAtlantic Inter-Society Consensus II C/D: 51% vs 11%; P = .001) and worse tibial runoff (P = .001). MetSyn patients required more complex interventions (P = .0001). There was no difference in mortality and major adverse cardiac events, but systemic complications (4% vs 1%; P = .001) and major adverse limb events (12% vs 7%; P = .0009) were significantly higher in the MetSyn group. Immediate postprocedural hemodynamic improvement, resolved or improved symptoms, and restoration of impaired ambulation were equivalent in both groups. Early failure (<6 months) was more common in those with MetSyn. At 5 years, primary, assisted primary, and secondary patencies were not affected by the presence of MetSyn. The presence of MetSyn was associated with a decrease in clinical efficacy, decreased freedom from recurrent symptoms, and decreased freedom from major amputation at 5 years.ConclusionsMetSyn is present in nearly half of the patients presenting with SFA disease. These patients present with more advanced disease and have poorer symptomatic and functional outcomes compared with those patients without MetSyn

Postchemoembolisation syndrome – tumour necrosis or hepatocyte injury?

Transarterial chemoembolisation of liver tumours is typically followed by elevated body temperature and liver transaminase enzymes. This has often been considered to indicate successful embolisation. The present study questions whether this syndrome reflects damage to tumour cells or to the normal hepatic tissue. The responses to 256 embolisations undertaken in 145 patients subdivided into those with hepatocyte-derived (primary hepatocellular carcinoma) and nonhepatocyte-derived tumours (secondary metastases) were analysed to assess the relative effects of tumour necrosis and damage to normal hepatocytes in each group. Cytolysis, measured by elevated alanine aminotransferase, was detected in 85% of patients, and there was no difference in the abnormalities in liver function tests measured between the two groups. Furthermore, cytolysis was associated with a higher rate of postprocedure symptoms and side effects, and elevated temperature was associated with a worse survival on univariate analysis. Multivariate analysis demonstrated that there was no benefit in terms of survival from having elevated temperature or cytolysis following embolisation. Cytolysis after chemoembolisation is probably due to damage to normal hepatocytes. Temperature changes may reflect tumour necrosis or necrosis of the healthy tissue. There is no evidence that either a postchemoembolisation fever or cytolysis is associated with an enhanced tumour response or improved long-term survival in patients with primary or secondary liver cancer

Cetuximab plus chronomodulated irinotecan, 5-fluorouracil, leucovorin and oxaliplatin as neoadjuvant chemotherapy in colorectal liver metastases: POCHER trial

Background:We assessed the effectiveness of cetuximab plus chronomodulated irinotecan, 5-fluorouracil (5-FU), leucovorin (FA) and oxaliplatin (L-OHP) (chrono-IFLO) administered as neoadjuvant chemotherapy to increase the resectability of colorectal liver metastases.Methods:This was a phase II prospective trial with rate of liver metastases resection as primary end point. Forty-three patients with unresectable metastases were enroled: 9 with metastases &gt;5 cm; 29 with multinodular (4) disease; 1 with hilar location; 4 with extrahepatic lung disease. Treatment consisted of cetuximab at day 1 plus chronomodulated irinotecan 5-FU, FA and L-OHP for 2-6 days every 2 weeks. After the first 17 patients, doses were reduced for irinotecan to 110 mg m 2, 5-FU to 550 mg m 2 per day and L-OHP to 15 mg m 2 per day.Results:Macroscopically complete resections were performed in 26 out of 43 patients (60%) after a median of 6 (range 3-15) cycles. Partial response was noticed in 34 patients (79%). Median overall survival was 37 months (95% CI: 21-53 months), with a 2-year survival of 68% in the entire population, 80.6% in resected patients and 47.1% in unresected patients (P=0.01). Grade 3/4 diarrhoea occurred in 93% and 36% of patients before and after dose reduction.Conclusion:Cetuximab plus chrono-IFLO achieved 60% complete resectability of colorectal liver metastases. © 2010 Cancer Research UK All rights reserved

Aszites, Pfortaderthrombose und hepatische Enzephalopathie bei Leberzirrhose: Aktuelle Therapieempfehlungen

Treatment of Ascites, Portal Vein Thrombosis and Hepatic Encephalopathy in Patients with Cirrhosis of the Liver Background: Ascites, portal vein thrombosis and hepatic encephalopathy are important complications of cirrhosis of the liver. Guidelines for the treatment of ascites have recently been published. Method: This manuscript summarizes up-to-date recommendations on the basis of the DGVS S3 guideline and of other guidelines as well as of the authors' experience. Results and Conclusions: TIPS (transjugular intrahepatic porto-systemic shunt) is the preferred treatment for refractory or recidivant ascites unless there are contraindications. The therapy of hepatorenal syndrome type 1 with albumin and the vasoconstrictor Terlipressin has been proven effective. Treatment of portal vein thrombosis comprises a strategy of anticoagulation, TIPS and liver transplantation. The most important therapeutic strategy for hepatic encephalopathy is the search for as well as the treatment of trigger events. Rifaximin is being increasingly used for the treatment and prophylaxis of hepatic encephalopathy
