Background. Аnkylosing spondylitis (AS) is closely associated with inflammatory bowel disease (IBD). 5–10 % of patients with SpA eventually develop inflammatory bowel disease, with Crohn's disease being more common than ulcerative colitis. Colonoscopy is usually used to diagnose inflammatory bowel disease, but this procedure is invasive. FC is clinically used to detect IBD and correlates well with clinical, endoscopic, and histological indicators of disease activity in IBD. The aim. To evaluate the incidence of inflammatory bowel disease in patients with ankylosing spondylitis. Materials and methods. In the analysis were included 40 patients with ankylosing spondylitis, among them 26 (65.0 %) men, and 14 (35.0 %) women, the average age of patients was 41.2 ± 10.5, the duration of the disease was on average 13.0 ± 8.8 years. All patients were examined with ESR, CRP, esophagogastroduodenoscopy, colonoscopy and quantitative analysis of the fecal calprotectin levels using the method of lateral immunochromatography with the BUHLMANN Quantum Blue rapid test. Standart range: 100–1,800 µg/g. Results. All patients had a high disease activity, the average BASDAI was 5.2 ± 1.7, the average ASDAS CRP 3.8 ± 1.1. 35 (87.5 %) patients had calprotectin level more than 100 µg/g, the remaining 5 (12.5 %) patients less than 100 µg/g. 12 (30.0 %) patients had the calprotectin level more than 1,800 µg/g, 23 (57.5 %) from 101 to 1800 µg/g. All patients with FC levels more than 100 µg/g showed an increase CRP level (mean 28.4 mg/l) and ESR (mean 36.3 mm/h). IBD were diagnosed in 9 (22.5 %) cases: 5 (12.5 %) patients with Crohn's disease and 4 (10 %) patients with ulcerative colitis, in the remaining (77.5 %) cases there was no intestinal pathology. Conclusion. The results showed high frequency of IBD in patients with AS. Patients with high fecal calprotectin levels (more than 100 μg/g) had high disease activity (AS). In most cases, inflammatory bowel disease were diagnosed in patients AS with fecal calprotectin levels more than 100 µg/g.
