However, these 2 patients presented with acute gastritis resulting from a Helicobacter pylori infection that may be a predisposing factor for developing IgA-anti-TG1 and/or IgA-anti-TG3 responses.When comparing IgA-anti-TG1, IgA-anti-TG2, and IgA-anti-TG3 responses using the Spearman’s rank correlation, a statistically significant correlation was noted between IgA-anti-TG1 and IgA-anti-TG2 response (r = 0.51), IgA-anti-TG3 and IgA-anti-TG2 response (r = 0.44) and between the IgA-anti-TG1 and IgA-anti-TG3 assay response (r = 0.70). This evidence concerns the gene CD79A and gastritis.
