Survival in patients with stage IV noncardia gastric cancer - the influence of DNA ploidy and Helicobacter Pyloriinfection

BACKGROUND: Palliative surgery followed by postoperative chemotherapy is a challenging approach in the treatment of stage IV gastric cancer yet patients must be carefully selected on the basis of likely clinical benefit. METHODS: The records of 218 patients with histological diagnosis of gastric adenocarcinoma who underwent palliative surgery followed by postoperative chemotherapy were retrospectively reviewed. Twelve potential prognostic variables including tumour DNA index and serum IgG anti- Helicobacter pylori (HP) antibodies were evaluated for their influence on overall survival by multivariate analysis. RESULTS: The median survival was 13.25 months [95% Confidence Interval (CI) 12.00, 14.50]. Three factors were found to have an independent effect on survival: performance status (PS) [PS 60–70 vs. 90–100 Hazard Ratio (HR) 1.676; CI 1.171-2.398, p = 0.005], liver metastases (HR 1.745; CI 1.318-2.310, p < 0.001), and DNA Index as assessed by Image cytometry (2.2-3.6 vs. >3.6 HR 3.059; CI 2.185-4.283, p < 0.001 and <2.2 vs. >3.6 HR; 4.207 CI 2.751-6.433 <0.001). HP infection had no statistically significant effect on survival by either univariate or multivariate analysis. CONCLUSION: Poor pre-treatment PS, the presence of liver metastasis and high DNA Index were identified factors associated with adverse survival outcome in patients with Stage IV gastric cancer treated with palliative gastrectomy and postoperative chemotherapy. HP infection had no influence on survival of these patients

Jejunogastric intussusception presented with hematemesis: a case presentation and review of the literature

BACKGROUND: Jejunogastric intussusception (JGI) is a rare but potentially very serious complication of gastrectomy or gastrojejunostomy. To avoid mortality early diagnosis and prompt surgical intervention is mandatory. CASE PRESENTATION: A young man presented with epigastric pain and bilous vomiting followed by hematemesis,10 years after vagotomy and gastrojejunostomy for a bleeding duodenal ulcer. Emergency endoscopy showed JGI and the CT scan of the abdomen was compatible with this diagnosis. At laparotomy a retrograde type II, JGI was confirmed and managed by reduction of JGI without intestinal resection. Postoperative recovery was uneventful. CONCLUSIONS: JGI is a rare condition and less than 200 cases have been published since its first description in 1914. The clinical picture is almost diagnostic. Endoscopy performed by someone familiar with this rare entity is certainly diagnostic and CT-Scan of the abdomen could also help. There is no medical treatment for acute JGI and the correct treatment is surgical intervention as soon as possible

Saccharomyces boulardii Improves Intestinal Cell Restitution through Activation of the α2β1 Integrin Collagen Receptor

Intestinal epithelial cell damage is frequently seen in the mucosal lesions of inflammatory bowel diseases such as ulcerative colitis or Crohn's disease. Complete remission of these diseases requires both the cessation of inflammation and the migration of enterocytes to repair the damaged epithelium. Lyophilized Saccharomyces boulardii (Sb, Biocodex) is a nonpathogenic yeast widely used as a therapeutic agent for the treatment and prevention of diarrhea and other gastrointestinal disorders. In this study, we determined whether Sb could accelerate enterocyte migration. Cell migration was determined in Sb force-fed C57BL6J mice and in an in vitro wound model. The impact on α2β1 integrin activity was assessed using adhesion assays and the analysis of α2β1 mediated signaling pathways both in vitro and in vivo. We demonstrated that Sb secretes compounds that enhance the migration of enterocytes independently of cell proliferation. This enhanced migration was associated with the ability of Sb to favor cell-extracellular matrix interaction. Indeed, the yeast activates α2β1 integrin collagen receptors. This leads to an increase in tyrosine phosphorylation of cytoplasmic molecules, including focal adhesion kinase and paxillin, involved in the integrin signaling pathway. These changes are associated with the reorganization of focal adhesion structures. In conclusion Sb secretes motogenic factors that enhance cell restitution through the dynamic regulation of α2β1 integrin activity. This could be of major importance in the development of novel therapies targeting diseases characterized by severe mucosal injury, such as inflammatory and infectious bowel diseases

Effects of Helicobacter pylori and nonsteroidal anti-inflammatory drugs on peptic ulcer disease: A systematic review

Background &amp; Aims: The aim was to systematically review the interactions between Helicobacter pylori (HP) infection and NSAID use on the risk of uncomplicated or bleeding peptic ulcer. Methods: All relevant full articles published in MEDLINE from January 1989-June 2004 were included. Sensitivity analyses for type of controls or use of aspirin or non-aspirin NSAIDs were performed. Results: In 21 studies involving 10,146 patients, uncomplicated peptic ulcer was more common in HP-positive than HP-negative patients (pooled odds ratio [OR], 2.17) or in HP-positive than HP-negative NSAID users (OR, 1.81). In 6 age-matched controlled studies, ulcer was more common in HP-positive than HP-negative patients (OR, 4.03), irrespective of NSAID use, and in NSAID users than non-users (OR, 3.10), irrespective of HP status; the risk of ulcer was 17.54-fold higher in HP-positive NSAID users than HP-negative non-users. The use of aspirin or non-aspirin NSAIDs did not affect the results. Ulcer bleeding was evaluated in 17 studies involving 4084 patients. NSAID use was more frequent in bleeding patients than control subjects (OR, 5.13), irrespective of HP status and type of controls. In contrast, HP infection in bleeding patients compared with control subjects was less frequent in the 8 studies with ulcer cases as control subjects (OR, 0.40) and more frequent in the 9 studies with uninvestigated subjects as controls (OR, 2.56). In the latter studies, presence compared with the absence of both HP and NSAIDs increased the risk of bleeding 20.834old. Conclusion: HIP infection and NSAID use represent independent and synergistic risk factors for uncomplicated and bleeding peptic ulcer

Does Helicobacter Pylori Identification in the Mucosa of the Gallbladder Correlate to Cholesterol Gallstone Formation?

ABSTRACT Objective: Helicobacter pylori (H pylori) represents a potential initiator of cholesterol crystallization and it has been proposed that it is related to gallstone formation. In this study, any possible association between the H pylori identification in the gallbladder’s mucosa and cholesterol gallstone formation, was evaluated. Methods: Gallbladders containing pure or mixed cholesterol gallstones (cholelithiasis group, n = 89) and gallbladders without gallstones (control group, n = 42) were submitted to standard histopathological examination for H pylori detection, as well as to nested polymerase chain reaction amplification for H pylori DNA detection. Results: Helicobacter pylori was identified in the gallbladder’s epithelium in four patients with the cholelithiasis and in two patients in the control group by histology. In all cases which were found to be H pylori positive by histological examination, H pylori DNA were also detected. No correlation between gallstone formation and H pylori detection in the biliary epithelium was found. A higher incidence of acute inflammation in the cholelithiasis (22.5% vs 9.5%, p = not significant [ns]) and in the H pylori positive groups (33% vs 17.6%, p = ns) were histologically detected. A higher incidence (10% vs 0%), p = ns) of H pylori in gallbladders with gallstones and acute inflammation, compared to gallbladders with acute inflammation but without gallstones, was noticed. Conclusion: Helicobacter pylori is detectable in low frequency in the mucosa of the gallbladder and it does not seem to act as a lithogenic component for cholesterol gallstone formation. Its higher incidence in gallbladders with gallstones and acute inflammation, suggests a possible accessory role in a subset of patients with cholelithiasis

Hypercalcemia in a patient with cholangiocarcinoma: A case report

Background. Humoral hypercalcemia of malignancy is rarely associated with cholangiocarcinoma (CC). Case report. A 77-year-old man was admitted with confusion. Computer tomography showed a large multinodular mass in the right lobe of the liver and smaller lesions in the right lung. Liver histology confirmed the diagnosis of CC. Elevated calcium levels and suppressed intact parathyroid hormone in the absence of skeletal metastases or parathyroid gland pathology suggested the diagnosis of humoral hypercalcemia of malignancy (HHM). Treatment of hypercalcemia with saline infusion, loop diuretics, biphosphonate and calcitonin was effective in normalizing calcium levels and consciousness state within 48 hours, but a relapse occurred 4 weeks later and the patient succumbed to his disease. Conclusion. Clinicians should be aware of this rare manifestation of CC as prompt and aggressive correction of hypercalcemia alleviates symptoms and improves patient&apos;s quality of life, despite the poor overall prognosis. © 2009 Xynos et al; licensee BioMed Central Ltd
