Background/aim: Inflammatory bowel disease (IBD) is a group of inflammatory conditions of the colon and small intestine. To our knowledge, no studies to date pertain to the profile of nail changes in IBD, except for onychomycosis. We aimed to study the frequency and pattern of nail changes among patients with IBD and evaluate their potential relationships with several parameters in IBD. Materials and methods: The study included 73 patients with IBD and 51 healthy control subjects. Nails of both groups were examined for changes with regard to color, striations, texture, curvature of nail plates, dystrophy of nail plates, and pigmentation. Mycological examinations were performed when onychomycosis was suspected. Results: Nail changes were statistically higher in patients with IBD than in the control group (P = 0.001). The presence of onychomycosis was significantly more common in patients with IBD (P = 0.041). Subungual hyperkeratosis and brownish discoloration of the nail were the most common findings in patients with IBD. Conclusion: Our study is the first report showing all nail changes in IBD. Further studies with more subjects are needed to reveal more detailed information about nail changes in IBD.
