Tu1844 Geranylgeranylacetone Protects Against Small-Intestinal Injuries Induced by Diclofenac in Patients With Rheumatic Diseases: A Prospective Randomized Study

a b s t r a c t Background: We aimed to explore the effect of geranylgeranylacetone on small-intestinal mucosal injuries induced by diclofenac sodium in patients with rheumatic diseases. Methods: The patients were randomly divided into two groups in our prospective study. The patients in the geranylgeranylacetone group received diclofenac sodium plus geranylgeranylacetone, and those in the control group received only diclofenac sodium for 12 weeks. We examined small-intestinal mucosal injuries using capsule endoscopy before and after treatment. Results: There were no significant differences between geranylgeranylacetone (n = 21, male: 42.9%; age: 31.0 ± 9.0 year) and control (n = 19, male: 68.4%; age: 31.0 ± 11.0 year) groups in terms of the numbers of patients with petechiae/red spots, denuded areas and mucosal breaks at baseline capsule endoscopy. After treatment, the numbers of patients with denuded areas (� 2 = 0.000, P = 1.000) and mucosal breaks (� 2 = 1.750, P = 0.186) did not increase in the geranylgeranylacetone group. However, the numbers of patients with petechiae/red spots (� 2 = 5.216, P = 0.022), denuded areas (� 2
