What other extraintestinal manifestations commonly occur with IBD and peripheral Spondyloarthritis?
About 30 years after diagnosis, approximately 50% of patients with IBD will have developed an extraintestinal manifestation (about 25% before diagnosis of IBD). Development of one extraintestinal manifestation increases the likelihood of having a second. The most common nonarticular extraintestinal manifestations can be remembered with the following mnemonic:
- P —Pyoderma gangrenosum (<2%)
- A —Aphthous stomatitis (<10%)
- I —Inflammatory eye disease (acute anterior uveitis; 2%–5%): more common in Crohn’s
- N —Nodosum (erythema; ∼15%)
