[Factor V-specific circulating anticoagulant and enteropathy. 2 cases]

Two patients with Factor V-specific circulating anticoagulant are presented: one had coeliac disease, the other Crohn's disease. In both patients the inhibitor appeared during flare-ups of the disease and disappeared during remission. This sequence was repeated after 1 year in one case, which seems to exclude a fortuitous association. No haemorrhage was observed. None of the usual aetiological circumstances was noted, which suggests that the condition was most probably auto-immune.
