title: Short report: the effect of misoprostol on the anaemia of NSAID enteropathy.
abstract: BACKGROUND
  Small bowel ulceration is an increasingly recognised complication of therapy with non-steroidal anti-inflammatory drugs (NSAID). The ulceration is a potent site of blood loss contributing to unexplained iron deficiency anaemia in patients with arthritis. No drug is currently available to treat NSAID small bowel ulcers.
  
  
  METHODS
  We have retrospectively examined the effect of therapy with the prostaglandin E1 analogue misoprostol on the anaemia of patients with enteroscopically proven NSAID small bowel enteropathy.
  
  
  RESULTS
  All of the patients had proven iron deficiency anaemia. Eleven patients received misoprostol and ten received no treatment. Haemoglobin in the misoprostol-treated group rose significantly from median (range) 9.1 (6.2-10.6) g/dL (95% confidence intervals 8.76, 10.13) to 10.6 (6.5-16.8) g/dL (95% confidence intervals 10.06, 11.82); P = 0.004). Those patients who did not receive misoprostol had no significant change in their haemoglobin: 9.1 (7.5-10.6) g/dL to 8.1 (5.6-14.7) g/dL (P = N.S.).
  
  
  CONCLUSIONS
  Misoprostol therapy was associated with an improvement in the anaemia in patients with proven NSAID enteropathy.
