Is measurement of basal levels of serum pepsinogen II useful in proving the eradication of Helicobacter pylori by treatment?
The eradication of Helicobacter pylori in patients with duodenal ulcer is associated with a significant decrease in the basal concentrations of serum pepsinogen II measured 5 months after completion of treatment. The verification of this decrease constitutes a useful, inexpensive non invasive method to prove the eradication of H. pylori with treatment.
The data suggest that while αVβ6 integrin is essential for CV-A9 in A549 cell line, it is not required in SW480 cell line in which β2M and HSPA5 alone are sufficient for CV-A9 infection. This suggests that the choice of CV-A9 receptor(s) is dependent on the tissue/cellular environment.
