Implication

Retrospective cohort study reveals increased risk of acute liver injury in adults taking non-steroidal anti-inflammatory drugs, indicating a small absolute excess risk.

Key Points

  • To evaluate the association between the use of non-steroidal anti-inflammatory drugs (NSAIDs) and serious, acute non-infectious liver injury.
  • Conducted a retrospective cohort study using a crossover design with provincial health database records from Saskatchewan, Canada (1982–1986).
  • Analyzed N=228,392 adults contributing 645,456 person-years who were current or past users of non-steroidal anti-inflammatory drugs.
  • Tracked NSAID prescriptions and identified hospital admissions for newly diagnosed acute non-infectious liver injury.
  • Identified 34 hospital admissions for acute liver injury, yielding an incidence rate of 9 per 100,000 person-years (95% CI, 6 to 15) among current NSAID users.
  • Current NSAID use showed an unadjusted rate ratio of 2.3 (95% CI, 1.1 to 4.9) and an age- and sex-adjusted rate ratio of 1.7 (95% CI, 0.8 to 3.7), corresponding to an excess risk of 5 per 100,000 person-years.
  • Excluding patients with concomitant hepatotoxic drug use yielded a rate ratio of 4.0 (95% CI, 0.9 to 19.0), whereas prolonged treatment duration showed no increased risk (rate ratio 1.0; 95% CI, 0.3 to 3.5).
