H. pylori infection

To investigate the prevalence of Helicobacter Pylori (H. Pylori) infection by the gastric biopsy for urease test and association with lesion imaging in patients undergoing oesophagogastroduodenoscopy (OGD).

The rate of antibiotic resistance in Helicobacter pylori (H.pylori) is increasing in Vietnam in recent years and has become a main challenge in the management of H. pylori infection. Data about the resistance remains different depending on the time, demography and especially the methods of determining the antibiotics susceptibility. To determine the antibiogram of H.pylori strains isolated from a population in Central Vietnam to clarithromycin, levofloxacin by E-test and disk diffusion, compare two diffusion methods.

Regulatory B cells (Bregs) produce antiinflammatory cytokines and inhibits proinflammatory response. Recently, immunosuppressive roles of Bregs in the effector functions of dendritic cells (DCs) were demonstrated. However, cross talk between Bregs and DCs in Helicobacter infection remains unknown. Here, we showed that direct stimulation of bone marrow-derived DCs (BMDCs) with Helicobacter felis (H.

 Less than 3 decades ago, Robin Warren and Barry Marshall definitively identified Helicobacter pylori by culturing an organism from gastric biopsy specimens that had been visualized for almost a century by pathologists (196). In 1994, H. pylori was recognized as a type I carcinogen, and now it is considered the most common etiologic agent of infection-related cancers, which represent 5.5% of the global cancer burden (239). In 2005, Marshall and Warren were awarded the Nobel Prize of Medicine for their seminal discovery of this bacterium and its role in peptic ulcer disease

Evaluation of patients with MALT lymphoma follows the pattern (Table 105-11) for staging a patient with non-Hodgkin's lymphoma. In particular, patients with gastric lymphoma need to have studies performed to document the presence or absence of H. pylori infection. Endoscopic studies including ultrasound can help define the extent of gastric involvement. Most patients with MALT lymphoma have a good prognosis, with a 5-year survival of ~75%. In patients with a low IPI score, the 5-year survival is ~90%, while it drops to ~40% in patients with a high IPI score.
