Serum Levels of Leptin As Marker For Patients At High Risk of Gastric CancerEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Background: Serological screening for gastric cancer (GC) may reduce mortality. However, optimal serum markers for advanced gastric precursor lesions are lacking.Aim: To evaluate in a case[ndash]control study whether serum leptin levels correlate with intestinal metaplasia (IM) and can serve as a tool to identify patients at high risk for GC.Materials and Methods: Cases were patients with a previous diagnosis of IM or dysplasia, controls were patients without such a diagnosis. All patients underwent endoscopy. Fasting serum was collected for the measurement of leptin, pepsinogens I/II, gastrin, and Helicobacter pylori. Rec...

Modulation of Activation-Induced Cytidine Deaminase by Curcumin in Helicobacter pylori-Infected Gastric Epithelial CellsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: Nonbactericidal concentrations of curcumin downregulated H. pylori-induced AID expression in gastric epithelial cells, probably via the inhibition of NF-[kappa]B pathway. Hence, curcumin can be considered as a potential chemopreventive candidate against H. pylori-related gastric carcinogenesis. (Source: Helicobacter)

Conclusions: The standard 7-day clarithromycin-containing triple therapy is still valid as the most effective empirical first-line eradication therapy for H. pylori infection in Hong Kong, as prevalence of primary resistance of H. pylori to amoxycillin and clarithromycin remains low. Patients who failed their empirical first-line eradication therapy should undergo H. pylori susceptibility testing to guide further treatment. (Source: Helicobacter)

Moxifloxacin-Containing Triple Therapy as Second-Line Treatment for Helicobacter pylori Infection: Effect of Treatment Duration and Antibiotic Resistance on the Eradication RateEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: The 7-day moxifloxacin-containing triple therapy produced an unacceptably low eradication rate. Increasing the duration of therapy was expected to increase the eradication rate, but the expected increased did not materialize, most likely because of coincident marked increase in the prevalence of resistance to moxifloxacin. Tailored treatment based on antibiotic susceptibility testing might be more effective in the achievement of high eradication rate when rapid antibiotic resistance such as moxifloxacin is occurring.

Conclusions: The eradication rate with a PPI, metronidazole and amoxicillin triple therapy was unacceptably low in South China.

Gastric cancer and peptic ulcer disease are both important in China making methods to effectively and efficiently eradicate H. pylori a priority. (Source: Helicobacter)

Annual Change of Primary Resistance to Clarithromycin among Helicobacter pylori Isolates from 1996 through 2008 in JapanEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: The resistance rate of H. pylori infection to clarithromycin in Japan has increased gradually to approximately 30% from 1996 through 2004, and remained unchanged since 2004.

Our results suggested that the level of clarithromycin resistance in Japan has now risen to the point where it should no longer be used as empiric therapy. (Source: Helicobacter)

Non-H. pyloriHelicobacter species (NHPHS) are associated with several important human and animal diseases. In the past year research into this group of bacteria has continued to gain attention, and novel species have been described in new niches owing to improvements in detection methods. Polymerase chain reaction and/or sequencing remain the gold standard for the detection of this genus. New insights into the pathogenesis of the NHPHS in hepatobiliary, gastric, and intestinal diseases were gained. In particular, data revealed interaction between hepatic steatosis and infectious hepatitis in the development of hepatocellul...

For two decades, Helicobacter pylori has been considered as the culprit in many extragastric manifestations. However, for several of these supposed associations the hypothesis of an etiological role has not yet been fully investigated. This may be due to a series of factors linked to the epidemiological features of the studies and to the diseases investigated. This review attempts to highlight the main reported associations of H. pylori with extragastric manifestations during the last year. The most convincing data arise in the field of idiopathic thrombocytopenic purpura (ITP) and sideropenic anemia. Long-term follow-up s...

This review summarizes the articles published on Helicobacter pylori infection in children between April 2008 and March 2009. Recent evidence highlights the decreasing prevalence trend of H. pylori infection and supports both intrafamilial and extrafamilial transmission. The association with various symptoms is still being debated. Interestingly, H. pylori infection seems inversely associated with allergic diseases. Monoclonal stool antigen tests are widely used and accurate for the diagnosis of H. pylori infection, but less accurate in young children. The new biprobe real-time PCR assay applied to stools showed a poor sen...

This article aims to examine current best practice in the field reference to first-line, second-line, rescue and emerging treatment regimens for Helicobater pylori eradication. The recommended first-line treatment in published guidelines in Europe and North American is proton pump inhibitor combined with amoxicillin and clarithromycin being the favoured regimen. Rates of eradication with this regimen however are falling alarmingly due to a combination of antibiotic resistance and poor compliance with therapy. Bismuth based quadruple therapies and levofloxacin based regimes have been shown to be effective second line regime...

In spite of important new insights into the basic mechanisms of gastric carcinogenesis, progress in the management of gastric cancer has been modest. Some modifications in the chemotherapies used for palliation and strategies for downstaging of the disease prior to surgical intervention are noteworthy. The positive experience with endoscopic mucosal resection (EMR) and submucosal dissection (ESD) for treatment of early gastric cancer has been confirmed and extended. The procedure-related morbidity and post-interventional quality of life is clearly favorable compared to open surgical resection in well-selected patients. New...
