[Time trends of H. pylori infection and related drug use in patients with peptic ulcer bleeding in a hospital in Beijing from 2010 to 2019].

Objective

To explore the time trends of H. pylori infection and related drug use in patients with peptic ulcer bleeding (PUB) in recent ten years.

Methods

PUB patients in Peking University Third Hospital from 2010 to 2019 were included. Time trends of H. pylori infection, related drugs (non-steroidal anti-inflammatory drugs, aspirin, antiplatelet drugs, anticoagulant drugs, glucocorticoids) use and non-H. pylori-non-drug ulcer in PUB patients were analyzed.

Results

A total of 1 140 PUB patients were included from 2010 to 2019 (including 925 males and 215 females). The age M(Q1,Q3)was 53.5 (33.0, 66.0) years, with 833 patients <65 years old. The positive rates of H. pylori were 79.3%, 75.7%, 73.1%, 71.6%, 77.0%, 70.4%, 69.7%, 63.1%, 51.4%, 50.9%, respectively, showing a decreasing trend (χ²=32.386, P<0.001), and the decreasing trends were significant in different ulcer location, age and gender subgroups(all P<0.05). The proportions of PUB patients using at least one of the above drugs were 23.1%, 28.6%, 34.0%, 39.5%, 33.8%, 35.9%, 28.7%, 39.8%, 40.9%, 41.8%, respectively, showing an increasing trend (χ²=6.857, P=0.009), and the proportions of patients with antiplatelet drugs and anticoagulant drugs history showed increasing trends. The proportions of non-H. pylori-non-drug patients were 12.3%, 22.1%, 14.6%, 13.2%, 7.7%, 13.0%, 16.9%, 18.7%, 22.6% and 20.9%, respectively, showing an increasing trend (χ²=4.808, P=0.028). Accordingly, the proportions of elderly (≥65 years old) patients (χ²=4.608, P=0.032) and large ulcer (≥2 cm) patients (χ²=8.173, P=0.004) showed increasing trends.

Conclusion

In the last decade, the positive rate of H. pylori in PUB patients showed a decreasing trend, while the proportions of patients with antiplatelet drugs and anticoagulant drugs history and the proportion of non-H. pylori-non-drug patients showed increasing trends.
