Abstract:
:We demonstrate that, in patients taking non-steroidal anti-inflammatory drugs (NSAIDs), there is inhibition of the proliferation of mucosal cells that normally leads to healing of duodenal ulcers. A microdissection technique was used to quantitate mitosis in duodenal crypts at the ulcer edge, giving a regeneration index of mitotic rate at that site, as compared to nearby mucosa. In patients with duodenal ulcers occurring in the absence of NSAID therapy, there was a brisk regenerative response (median index 2.48, range 1.55-9.81, n = 8), significantly greater than in patients taking NSAIDs (median index 1.10, range 0.73-2.16, n = 10, p = 0.014). Inhibition of the process of epithelial cell division normally involved in duodenal ulcer healing could contribute to the delay in ulcer healing which may explain the higher complication rate for duodenal ulcer during NSAID therapy.
