Urease, Gastric Bacteria and Gastritis
Urease is an enzyme produced by diverse bacterial species including normal flora, non pathogens, and pathogens such as Proteus mirabilis, Staphylococcus saprophyticus, Klebsiella pneumonia, Citrobacter freundii, Enterobacter cloacae Helicobacter spp and Helicobacter pylori. Urease is central in Heli...

| description | Urease is an enzyme produced by diverse bacterial species including normal flora, non pathogens, and pathogens such as Proteus mirabilis, Staphylococcus saprophyticus, Klebsiella pneumonia, Citrobacter freundii, Enterobacter cloacae Helicobacter spp and Helicobacter pylori. Urease is central in Helicobacter pylori metabolism and virulence, important for colonization in the gastric mucosa. Urease catalyzes the hydrolysis of urea to ammonia and carbamate. This ammonia product can be examined by Urease biopsy test and Urea breath test such as 14C-Urea Breath Test or 13C-Urea Breath Test.
Previously, the Urea breath test was intended to detect an increase in ammonia which is a urease product in the gastric mucosa produced by pathogenic gastric bacteria, such as Helicobacter pylori, etc.
Acute and chronic gastritis caused by infection with these pathogenic bacteria infection turned out to be positive on Urea breath test. Indirectly, the results of the urea breath test are also related to the presence of inflammation in acute and chronic gastritis, regardless of whether the cause is Helicobacter pylori or other urease-producing pathogenic bacteria.
The use of the urea breath test indirectly in diagnosing acute and chronic gastritis should be studied further. The use of the urea breath test is indeed very important to assist health services in countries and regions with limited endoscopic facilities, especially developing countries.
We know that the prevalence of Helicobacter pylori infection in causing acute and chronic gastritis by examination of Urea breath test in Indonesia is not too high, ranging from 2-11.2%. So that is why more studies on non-Helicobacter pylori producing urease pathogens are needed, which can appear as a false positive urea breath test.
