Correlation of anti-Helicobacter pylori cagA IgG antibodies with resistance to first line treatment, bleeding gastroduodenal ulcers and gastric cancer.

CONCLUSIONS: CagA positive H. pylori are virulent strains and the cagA IgG antibodies titer is associated with persistence of infection after treatment, upper gastroduodenal ulcers or gastric cancer. The presence of these antibodies, associated with positive biopsy for H. pylori, indicates the need of H. pylori treatment. PMID: 22570922 [PubMed - indexed for MEDLINE]
