Abdominal angina due to recurrence of cancer of the papilla of Vater: a case report

Abdominal angina is usually caused by atherosclerotic disease, and other causes are considered uncommon. This is the first report of a case of abdominal angina secondary to neoplastic vascular stenosis caused by local recurrence of an adenocarcinoma of the papilla of Vater. CASE PRESENTATION: An 80-year-old woman of Caucasian origin presented with abdominal pain and diarrhea. She had undergone a pancreaticoduodenectomy for adenocarcinoma of the papilla of Vater four years earlier. Computed tomography revealed a mass surrounding her celiac trunk and superior mesenteric artery. Her abdominal pain responded poorly to analgesic drugs, but disappeared when oral feedings were withheld. A duplex ultrasonography of the patient's splanchnic vessels was consistent with vascular stenosis. Parenteral nutrition was started and the patient remained pain free until her death. CONCLUSION: Pain relief is an important therapeutic target in patients with cancer. In this case, abdominal pain was successfully managed only after the ischemic cause had been identified. The conventional analgesic therapy algorithm based on nonsteroidal anti-inflammatory drugs and opioids had been costly and pointless, whereas the simple withdrawal of oral feeding spared the patient of the discomfort of additional invasive procedures and allowed her to spend her remaining days in a completely pain-free state

prognostic ability of bclc b subclassification in patients with hepatocellular carcinoma undergoing transarterial chemoembolization

Abstract Background and aims. A subclassification system for intermediate hepatocellular carcinoma (HCC) was recently proposed to optimize treatment allocation. The aim of this study was to assess the prognostic ability of that substaging proposal. Patients and methods. This is a retrospective multicenter cohort study including patients with intermediate HCC treated with transarterial chemoembolization (TACE). Predictors of survival were identified using the Cox proportional regression model. Results. 289 Barcelona Clinic Liver Cancer (BCLC) B patients were included. Median overall survival of the whole cohort was 23 months (C.I. 95% 20.2– 25.8). Child A status (H.R. 1.35, C.I. 95% 1.02–1.78) and tumour burden beyond the up-to-seven criterion (H.R. 1.39, C.I. 95% 1.07– 1.80) were independent prognostic factors for overall survival on multivariate analysis. Analysis of the substages showed that median survival was 33.0 months for B1 stage (n = 81), 20.8 months for B2 stage (n = 106), 16.1 months for B3 stage (n = 24), 22.2 months for B4 stage (n = 42) and 15.0 months for quasi-C stage (n = 36). Regarding the discriminatory ability of the substaging proposal, the log rank test showed a significant survival difference for B1 vs. B4 (p = 0.003) and B1 vs. Quasi-C (p = 0.039) and a trend for B1 vs. B2 (p = 0.05) and B1 vs. B3 (p = 0.05). Conclusions. Apart from substage B1, BCLC-B subclassification does not discriminate perfectly patients treated with TACE. Also some patients in substage B4 can benefit from TACE

Serum levels of hyaluronic acid and tissue metalloproteinase inhibitor-1 combined with age predict the presence of nonalcoholic steatohepatitis in a pilot cohort of subjects with nonalcoholic fatty liver disease

Hyaluronic acid (HA) and tissue inhibitor of metalloproteinase 1 (TIMP-1) are reliable markers of liver fibrosis and are closely linked to the proinflammatory status. In this pilot cohort study, we attempted to identify a clinical score that would predict the severity of nonalcoholic fatty liver disease (NAFLD) based on clinical variables and serum markers of fibrosis and inflammation. The cohort included 46 patients with histologically confirmed WILD (76.1% male; mean age, 43 +/- 13 years; mean body mass index (BMI), 27.8 +/- 3.5). Serum transforming growth factor beta (TGF-beta), HA, TIMP, and matrix metalloproteinase (MMP) levels were measured with commercial enzyme-linked immunoassay (ELISA) kits. Demographic features and clinical and laboratory findings were subjected to univariate and multivariate binary logistic regression analysis to construct the mathematical model. Receiver operating characteristic curve (ROC) analysis was used to identify a threshold value for diagnosis of NASH and to assess its sensitivity and specificity. Serum levels of HA and TIMP-1 were statistically different in patients with nonalcoholic steatohepatitis (NASH) (P < 0.05). Logistic regression analysis of several clinical variables indicated patient age as the only independent predictor of NASH (odds ratio (OR), 1.129, 95% confidence interval (0), 1.019-1.251, P = 0.020). The mathematical model constructed on the basis of these results included age, TIMP-1, and HA levels. A value of 148.27 or more identified patients with NASH with 85.7% sensitivity, 87.1% specificity, and negative and positive predictive values of 96.4% and 60%, respectively. This model seems to represent a reliable noninvasive tool for excluding the presence of NASH. If validated in larger prospective cohort studies, it might be useful for determining when a liver biopsy is actually warranted in patients with NAFLD. (Translational Research 2009; 154:194-201

[The treatment of hepatocellular carcinoma: an update]

Hepatocellular carcinoma (HCC) is the third most frequent cause of death from cancer with an increasing incidence in the world. Hepatic cirrhosis is the main risk factor for the development of this tumor, present in more than 80% of cases. The prognosis of this tumor is still poor and appears to be strictly related to liver residual function and tumor extension. A regular surveillance program was defined to increase early detection of tumor in cirrhotic patients when curative treatment could be applied. Liver transplantation and liver resection offer a high rate of positive response when applied in a early stage of the disease; locoregional therapies are effective, palliative options for patients with unresectable HCC: transarterial chemoembolisation being the only with a proven positive impact on survival. Several prognostic systems are proposed in the last years to stratify patients in different risk groups and to identify those who could achieve the best survival benefit from different therapeutic strategies: the Okuda system, the Cancer of the Liver Italian Program and the Barcelona Cl\uednic Liver Cancer are the most widely used, but there is no consensus to which is the best in predicting outcome most accurately

Severe giant cell arteritis associated with essential thrombocythaemia.

Giant-cell arteritis (GCA) is a chronic vasculitis of the elderly usually involving the ophthalmic arteries, which can result in visual loss. High platelet counts may have some pathogenic significance in the obstruction of the ophthalmic circulation and a few cases of associated essential thrombocythaemia and GCA have been described. Here we report a case of severe temporal arteritis associated with essential thrombocythaemia

Transarterial chemoembolization (TACE) for unresectable HCC: a new life begins?

BACKGROUND AND OBJECTIVES: To provide an overview on the loco-regional therapy performed by transarterial chemoembolization (TACE) in patients with hepatocellular carcinoma (HCC), either as sole, either as neoadjuvant to surgery or bridge therapy to orthotopic liver transplantation (OLT). EVIDENCE AND INFORMATION SOURCES: The current review is based on an analysis of the current literature and the caseload experience of the Authors on this topic. STATE OF THE ART: Chemoembolization combines de-arterialization of the tumor and selective delivery of chemotherapeutic agents into tumor's feeding vessels during angiography. Tumor ischemia raises the drug concentration compared to infusion alone and extends the retention of the chemotherapeutic drug. As locoregional therapy, TACE allows a complete local tumor control of 25-35% and permits an increase of survival in patients with intermediate HCC according to Barcelona-Clinic Liver Cancer (BCLC) classification. Excellent results were also achieved by combined therapies, such as with percutaneous ethanol injection or radiofrequency ablation, as neoadjuvant therapy prior to liver resection and in some circumstances as a bridging tool before liver transplantation. PERSPECTIVES: Drug eluting beads are microspheres that can be loaded with doxorubicin and induce toxic and ischemic necrosis with the same device; that allows an increase of drug selectively exposed to tumor cells and simultaneously a reduction of systemic toxicity. Tumor embolization induces a neoangiogenic reaction with a significant growth of adiacent satellites, so the association with sorafenib has a strong rationale for a combined therapy and is currently under investigation. CONCLUSIONS: Today TACE is the standard of care for treatment of intermediate hepatocellular carcinoma. To get the best performance it should be tailored according to the individual patient's condition

[Helicobacter pylori infection: from gastric to systemic disease]

H. pylori infection, through a chronic stimulation of the immune system and the occurrence of molecular mimicry mechanisms, is responsible for the majority of the gastroduodenal diseases and also for some extragastric disorders, including sideropenic anemia and idiopathic thrombocytopenic purpura; other diseases are under investigation

Intestinal permeability after Mediterranean diet and low-fat diet in non-alcoholic fatty liver disease

BACKGROUND: In non-alcoholic fatty liver disease (NAFLD), a high-fat or high-fructose diet increases intestinal permeability and promotes derangement of the gut-liver axis. We hypothesize that, diet could be able to modulate intestinal permeability in patients with NAFLD. AIM: To detect diet-induced modification of intestinal permeability in patients with NAFLD undergoing a Mediterranean diet or a low-fat diet. METHODS: The current study was a dietary intervention for non-diabetic, patients with biopsy-verified NAFLD and increased transaminases. A crossover design was employed: participants underwent 16 weeks of Mediterranean diet, 16 wk of free wash-out, and 16 weeks of low-fat diet. Both diets were hypocaloric and no consumption of supplements was allowed. All patients were followed bimonthly by a dietitian. Evaluations of clinical and metabolic parameters were completed at baseline and at the end of each dietary period. Intestinal permeability was assessed by chromium-51 ethylene diamine tetraacetate excretion testing (51Cr-EDTA). RESULTS: Twenty Caucasian patients, 90% male, median age 43 years, body mass index (BMI) 30.9, with biopsy-verified NAFLD were enrolled. At the end of 16 weeks of a Mediterranean diet, a significant reduction in mean body weight (-5.3 \ub1 4.1 kg, P = 0.003), mean waist circumference (-7.9 \ub1 4.9 cm, P = 0.001), and mean transaminase levels [alanine aminotransferase (ALT) -28.3 \ub1 11.9 IU/L, P = 0.0001; aspartate aminotransferase (AST) -6.4 \ub1 56.3 IU/L, P = 0.01] were observed. These benefits were maintained after 16 wk of wash-out and also after 16 wk of low-fat diet, without further improvements. Fourteen of the 20 patients had intestinal permeability alteration at baseline (mean percentage retention of 51Cr-EDTA = 5.4%), but no significant changes in intestinal permeability were observed at the end of the 16 wk of the Mediterranean diet or 16 wk of the low-fat diet. CONCLUSION: Mediterranean diet is an effective strategy for treating overweight, visceral obesity and serum transaminase in patients with NAFLD. If the Mediterranean diet can improve intestinal permeability in patients with NAFLD, it deserves further investigation
