Influence of proton pump inhibitor treatment on Helicobacter pylori stool antigen test

Figure 1 Urea breath test results (¹³CO₂/¹²CO₂ ratios) before and after proton pump inhibitor treatment. UBT results in all 28 patients were not altered by PPI treatment (P = 0.068). However, among patients treated for ≥ 4 wk, UBT results decreased significantly after PPI treatment (P = 0.048). UBT: Urea breath test; PPI: Proton pump inhibitor.

Figure 2 Stool antigen test results (A₄₅₀/A₆₃₀ ratios) before and after proton pump inhibitor treatment. PPI treatment did not significantly alter stool antigen test results, both in all patients (P = 0.989) and in those treated for ≥ 4 wk (P = 0.099). PPI: Proton pump inhibitor.
