    Abstract:
    Takayasu's arteritis and Crohn's colitis are exceptionally associated and characteristics of patients affected with both diseases have not been fully described. In a group of 44 consecutive Takayasu patients, 4 also had Crohn's disease. This 9% prevalence (95% confidence interval=2.5-21.7%) of Crohn's disease in the group is significantly greater than the highest reported prevalence of the disease in the general population. In these 4 patients, fulfilling 5 or more ACR criteria for Takayasu's disease, Crohn's disease was confirmed with colonoscopic examination and biopsies. Takayasu-Crohn patients were younger at diagnosis and tended to have systemic symptoms more frequently. Other clinical, radiological and biological characteristics were not different between the 2 groups. In the literature, 16 cases of this unusual association have been reported. The diagnosis of Takayasu's disease was simultaneous or posterior to Crohn's disease in 87%. Data on vascular lesions was available in 6 out of 16 patients and in the 4 patients of the present study: the distribution of vascular lesions in Takayasu-Crohn patients did not appear to be different from Takayasu patients. Our results and previous reports suggest that this association of rare diseases is not fortuitous. With respect to the indolent course of Takayasu's arteritis, early diagnosis of vascular lesions in Crohn patients is encouraged.
