Abstract
AIM
To determine the sensitivity and specificity of the 13C-urea breath test (UBT) in patients taking proton pump inhibitors (PPIs), using a new test meal Refex.
METHODS
One hundred and fourteen consecutive patients with dyspepsia, 53 Helicobacter pylori (H. pylori) positive, 49 H. pylori negative, were included in the study. The patients were then given esomeprazole 40 mg for 29 consecutive days, and the 13C-UBT with the new test meal was performed the next morning.
RESULTS
The sensitivity of the 13C-UBT with a cut off 2.5‰ was 92.45% (95%CI: 81.79%-97.91%) by per-protocol (PP) analysis and 78.13% (95%CI: 66.03%-87.49%) by intention-to-treat (ITT) analysis. The specificity of the 13C-UBT test was 96.00% in the ITT population (95%CI: 86.29%-99.51%) and 97.96% in the PP population (95%CI: 89.15%-99.95%).
CONCLUSION
The new test meal based 13C-UBT is highly accurate in patients on PPIs and can be used in those unable to stop their PPI treatment.
