Helicobacter pylori management in non-steroidal anti-inflammatory drug therapy patients in primary care

摘要

Non-steroidal anti-inflammatory drugs (NSAIDs) may cause gastroduodenal ulcers and its complications. Helicobacter pylori infection is recognized as an additional risk factor for ulcer development, its eradication in NSAIDs users being recommended. In this cross-sectional study, during a 1-week period, consecutive patients who were routinely visiting in 58 primary care clinics were enrolled. A questionnaire was used to collect clinical data on the patients who were chronically taking NSAIDs. Patients with age 65 years, a personal history of peptic ulcer, concomitant therapy with steroids, anti-coagulants, multiple NSAIDs, or relevant co-morbidities were considered at high risk for NSAIDs gastroduodenal complications. Data on H. pylori infection management were collected. Overall, H. pylori was searched for in 140 (16.1%) out of 869 patients receiving chronic NSAID therapy, and it was eventually cured in 43 (72.9%) of the infected cases. In detail, H. pylori status was not investigated in 670 (77.1%) of those patients at high risk of NSAID-related gastroduodenal lesions, including 516 patients ≥65 years old, and 154 younger, but with at least 1 adjunctive risk factor. In addition, 234 (35%) of these high-risk patients were not receiving any gastric mucosa protection. Our data find that H. pylori infection is investigated in fewer than one of every five NSAID-user patients in primary care. The low alertness towards such an infection in these patients suggests a need for prompt implementation of current guidelines.
