The success of H. pylori cure depends on the type and duration of therapy, patient compliance and bacterial factors such as antibiotic resistance. Patients most often fail to respond to initial H. pylori eradication therapy because of noncompliance or antibiotic resistance. Patients should be queried about any side effects, missed doses, and ...
Several anti-ulcer dosing regimens that combine antibiotics and proton pump inhibitors (PPI) to treat helicobacter pylori (H. pylori) induced peptic ulcer disease (PUD). The role of antibiotic in the therapies is to eradicate H. pylori, while the action of PPI is to reduce gastric acid secretion. The anti-ulcer dosing regimens generally repair ...
H. pylori is able to adhere to the surface of the phagocytes and impede their action. This is responded to by the phagocyte in the generation and release of oxygen metabolites into the surrounding space. H. pylori can survive this response by the activity of catalase at its attachment to the phagocytic cell surface. Catalase decomposes hydrogen ...
Helicobacter heilmannii s.s. (H. heilmannii s.s.) is a species within the Helicobacter genus of Gram negative bacteria. [1] Helicobacter pylori (H. pylori) is by far the best known Helicobacter species primarily because humans infected with it may develop gastrointestinal tract diseases such as stomach inflammation, stomach ulcers, duodenal ulcers, stomach cancers of the non-lymphoma type, and ...
Gastritis caused by H. pylori infection is termed Helicobacter pylori induced gastritis, and listed as a disease in ICD11. [ 6 ] [ 7 ] More than 80% of individuals infected with the bacterium are asymptomatic and it has been postulated that it may play an important role in the natural stomach ecology.
Owing to the causal relationship between H. pylori infection and gastric MALT lymphoma, identification of the infection is imperative. Histological examination of GI biopsies yields a sensitivity of 95% with five biopsies, [7] but these should be from sites uninvolved by lymphoma and the identification of the organism may be compromised by areas of extensive intestinal metaplasia.
Gastric outlet obstruction (GOO) is a medical condition where there is an obstruction at the level of the pylorus, which is the outlet of the stomach.Individuals with gastric outlet obstruction will often have recurrent vomiting of food that has accumulated in the stomach, but which cannot pass into the small intestine due to the obstruction.
Patients swallow urea labelled with an uncommon isotope, either radioactive carbon-14 (nowadays preferred in many countries) or non-radioactive carbon-13.In the subsequent 10–30 minutes, the detection of isotope-labelled carbon dioxide in exhaled breath indicates that the urea was split; this indicates that urease (the enzyme that H. pylori uses to metabolize urea to produce ammonia) is ...
