| アブストラクト | BACKGROUND: Few epidemiologic studies have investigated predictors of uncomplicated peptic ulcer disease (PUD) separately from predictors of complicated PUD. OBJECTIVE: To analyze risk factors associated with uncomplicated PUD and medication use after diagnosis. METHODS: Patients diagnosed with uncomplicated PUD (n = 3,914) were identified from The Health Improvement Network database among individuals aged 40-84 years during 1997-2005, with no previous history of PUD. Prescription records for the year after the date of diagnosis were reviewed and a nested case-control analysis was performed to calculate the odds ratios for the association of potential risk factors with PUD. RESULTS: Medications associated with developing uncomplicated PUD included current use of acetylsalicylic acid (ASA), nonsteroidal anti-inflammatory drugs (NSAIDs), paracetamol, selective serotonin reuptake inhibitors, antidepressants, antihypertensives or acid suppressants. Uncomplicated PUD was significantly associated with being a current or former smoker and having had a score of at least 3 on the Townsend deprivation index. Approximately 50% of patients who were users of ASA (19% of patients) or chronic users of NSAIDs (7% of patients) at diagnosis did not receive another prescription of the medication in the 60 days after diagnosis, and 30% were not represcribed therapy within a year. Among patients who were current users of ASA or chronic NSAIDs at the time of the PUD diagnosis and received a subsequent prescription for their ASA or NSAID during the following year, the vast majority (80-90%) also received a proton pump inhibitor coprescription. CONCLUSIONS: Our results indicate that several risk factors for upper gastrointestinal bleeding are also predictors of uncomplicated PUD, and that some patients do not restart therapy with ASA or NSAIDs after a diagnosis of uncomplicated PUD. Further investigation is needed regarding the consequences for these patients in terms of increased cardiovascular burden due to discontinuation of antiplatelet therapy. |
