BACKGROUND/AIMS: Although the efficacy of first-line treatment for Helicobacter pylori infection should aim to be > 90%, it is unclear whether this target has been achieved in Israel. We aimed to determine the success rate of treatment for H. pylori and to describe temporal changes in our region. Methods: Adult patients who underwent a first-time -C13-urea breath test (C13-UBT) at Clalit Health Services between January 1, 2010 and December 31, 2015 were included. In order to isolate a naïve "test-and-treat" population who were unlikely to have undergone an initial endoscopy-based H. pylori test, we excluded patients ≥45 years and those with any previous C13-UBT. RESULTS: A total of 94,590 subjects (36.1% male, age 28.5 ± 6.0) who underwent at least one C13-UBT during the study period were included. C13-UBT was positive in 48,509 (51.3%) subjects. A confirmatory post-treatment C13-UBT was performed in 37.8, 44.1, 46.6, and 45.9% following 1st, 2nd, 3rd, and 4th-line treatment respectively. Eradication was successful in 65.4% following first-line treatment, and eradication success improved during the study period (59.2, 63.3, 65.7, 66.0, 69.0, and 73.1% in 2010, 2011, 2012, 2013, 2014, and 2015 respectively; OR 1.11; 95% CI 1.09-1.13; p < 0.0001). Eradication was successful in 44.7% following second-line treatment, although eradication success did not significantly improve during the study period (OR 1.05; 95% CI 0.99-1.10; p = 0.09). CONCLUSIONS: Despite the increasing success of first-line treatment for H. pylori infection over the study period, eradication rates remain suboptimal. Initiatives to implement the Toronto and Maastricht Consensus Reports should be advanced.
