B. Godeau et al., HYPERSENSITIVITY TO AZATHIOPRINE MIMICKING GASTROENTERITIS - ABSENCE OF RECURRENCE WITH B-MERCAPTOPURINE, Gastroenterologie clinique et biologique, 19(1), 1995, pp. 117-119
Hypersensitivity mimicking gastroenteritis is a rare complication of a
zathioprine therapy for which the mechanism is unknown. We report a ca
se of devastating diarrhoea and vomiting due to azathioprine treatment
in which hypersensitivity to the imidazole moiety of azathioprine was
demonstrated. This has important therapeutic implications in this sit
uation, 6-mercaptopurine, which is the portion of azathioprine respons
ible for the cytotoxic therapeutic effect, can be administered without
recurrence of side-effects.
