Mucosal healing of Crohn’s disease in a patient with concurrent systemic lupus erythematosus using infliximab

Abstract

We describe a patient with Crohn's disease (CD) concurrent with systemic lupus erythematosus (SLE). Continuous prednisolone and cyclosporine treatment resulted in no recurrent symptoms. However, diarrhea, vomiting, and fever occurred for approximately 3 months. A colonoscopy was then performed, which showed a discontinuous cobblestone appearance and longitudinal ulcers extending from the sigmoid colon to the descending colon and distal ileum. A biopsy revealed a noncaseating granulomatous lesion in the colonic mucosa. These findings led to a diagnosis of CD concurrent with SLE. We first attempted treatment with a full elemental diet, mesalazine, and azathioprine, in that order. However, as there was no improvement in inflammation, we started infliximab, a tumor necrosis factor-alpha inhibitor. Transanal double-balloon enteroscopy performed 4 months after starting infliximab showed mucosal healing, suggesting that infliximab was effective. There are few reports of treating patients with CD concurrent with SLE using a tumor necrosis factor-alpha inhibitor. We report our experience with a patient who had mucosal healing with infliximab and review the literature.
