Background:Аnkylosing spondylitis (AS) and inflammatory bowel diseases (IBD) have many common features. Approximately one in two patients with axial spondyloarthritis have subclinical (histologically confirmed) inflammation of the intestine, and 5-10% of subclinical inflammation turns into Crohn’s disease (CD) or Ulcerative colitis (UC) [1]. Colonoscopy is usually used to diagnose IBD, but this procedure is invasive. Laboratory biomarkers, as fecal calprotectin (FC) and serum calprotectin (SC) can used to diagnosis of IBD. But there is no consensus regarding SC clinical utility. SC is exposed to proteolytic enzymes, but its level also increases with inflammation in the intestine and is associated with a higher disease activity [2]. SC levels positively correlate with CRP, ESR, disease activity in AS, but not as obvious as with FC [3,4].Objectives:The aim of this study was to evaluate the possibility of using SC in the diagnosis of IBD in patients with AS.Methods:In the analysis were included 50 patients with AS, fulfilling the modified New York criteria, among them man -36 (72%), woman -14 (28%), mean age of patients was 42.5 ±9.9, mean disease duration – 13.4±8.7 years. All patients were examined with ESR, CRP, FC (range: 100-1800 µg /g), esophagogastroduodenoscopy, colonoscopy and quantitative analysis of the SC level using ELISA (BUHLMANN MRP8/14 ELISA, range: 0.4-3.9 µg /ml).Results:All patients had a high disease activity, mean BASDAI was 5.3 ± 1.8, mean ASDAS CRP 3.7 ± 1.01, mean ASDAS ESR 3.6 ± 1.01. 80 % patients had high FC level (more than 100 µg / g), while only 18% patients had an increase of SC level. IBD were diagnosed in 11 cases: 6 patients (12 %) with CD and 5 patients (10 %) - UC, in the remaining cases (78%) was no intestinal pathology. Only 2 patients with IBD had a high SC level. SC level was more correlated with ESR (r=0.5) and CRP (r=0.5) (p <0.05) levels, than with FC level (r=0.4) (p <0.05).Conclusion:The results showed that there is currently insufficient data to assess the possibility of using SC in the diagnosis of IBD in patients with AS. There is a significant association between the SC, CRP and ESR, but not fecal calprotectin. Potentially SC may be more representative of systemic inflammation than an intestinal inflammation.References:[1]Klingberg, E., Strid, H., Stahl, A.et al.

Background:Аnkylosing Spondylitis (AS) is closely associated with inflammatory bowel disease (IBD). About 6-46% of patients with IBD have various lesions of the musculoskeletal system [1]. 5-10% of patients with spondylarthritis (SpA) eventually develop IBD, with Crohn’s disease (CD) being more common than Ulcerative colitis (UC) [2]. Determining the level of fecal calprotectin (FC) is a study that allows to diagnose IBD. The concentration of FC directly depends on the neutrophil infiltration of the intestinal mucosa and has a direct connection with the activity of the inflammatory process [3]. It is known that level of FC increases in 2/3 of patients with AS and is closely related to parameters reflecting higher disease activity [4].Objectives:The aim of this study was to evaluate the frequency of IBD in patients with AS using an assessment of FC level.Methods:In the analysis were included 40 patients with AS, fulfilling the modified New York criteria, among them man -26 (65%), woman -14 (35%), mean age of patients was 41.2 ±10.5, mean disease duration - 13±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: 100-1800 µg /g.Results:All patients had a high disease activity, mean BASDAI was 5.2 ± 1.7, mean ASDAS CRP 3.8 ± 1.1. 35 patients (87.5 %) had FC level more than 100 µg / g, the remaining 5 patients (12.5%) less than 100 µg /g. 12 patients (30 %) had FC level more than 1,800 µg / g, 23 (57.5 %) from 101 µg / g to 1800 µg / g. All patients with FC levels more than 100 µg / g showed an increase CRP (mean 28.4 mg / l) and ESR (mean 36.3 mm\h) levels. IBD were diagnosed in 9 cases (22.5%): 5 patients (12.5 %) with CD and 4 patients (10 %) - UC, in the remaining cases (77.5%) was no intestinal pathology.Conclusion:The results showed high frequency of IBD in patients with AS. Patients with high FC levels (more than 100 μg/g) had high disease activity (AS). In most cases, inflammatory bowel disease were diagnosed in patients with FC levels more than 100 µg/g.References:[1] Bernstein CN, Blanchard JF, Rawsthorne P, Yu N.

Inflammatory Bowel

Inflammasomes are intracellular multiprotein complexes that coordinate the maturation of interleukin (IL)-1β and IL-18 in response to pathogens and metabolic danger. Both cytokines have been linked to intestinal inflammation. However, recently evolving concepts ascribe a major role to the inflammasome in maintaining intestinal homeostasis. This review recapitulates its position in the development of inflammatory bowel disease, thereby outlining a model in which hypo- as well as hyperfunctionality can lead to an imbalance of the system, depending on the specific cell population affected. In the epithelium, the inflammasome is essential for regulation of permeability and epithelial regeneration through sensing of commensal microbes, while excessive inflammasome activation within the lamina propria contributes to severe intestinal inflammation.

Background. Patients with inflammatory bowel diseases (IBD) often have lesions of the musculoskeletal system, which is an extra-intestinal manifestation and mainly belongs to the group of seronegative spondyloarthritis (SPA). Ankylosing spondylitis (AS) is one of the main forms of diseases from the group of spondyloarthritis, associated with IBD. The frequency of AS in patients with IBD is of interest for elucidating the general pathophysiology of diseases. Colonoscopy is required to diagnose intestinal pathology. Colonoscopy in patients with AS to detect IBD, especially in the absence of intestinal symptoms, is very diffcult. Mainly for the diagnosis of IBD, the defnition of fecal calprotectin is used. Recently, there has been an interest in serum calprotectin, an increase in which is associated with a higher activity of the disease and is a marker of the intensity of inflammation in the intestine. However, there is currently no consensus on the clinical signifcance for serum calprotectin.The aim. To evaluate the role of serum calprotectin in diagnosis of inflammatory bowel disease in patients with ankylosing spondylitis.Materials and methods. In the analysis were included 50 patients with AS, fulflling the modifed New York criteria, among them were 36 (72%) men and 14 (28%) women, the mean age of patients was 42.5 ± 9.9, mean disease duration was 13.4 ± 8.7 years. All patients were examined with ESR, CRP, FC (range: 100–1800 µg/g), esophagogastroduodenoscopy, colonoscopy and quantitative analysis of the SC level using ELISA (Buhlmann MRP8/14 ELISA, range: 0.4–3.9 µg/ml).Results. All patients had a high disease activity, mean BASDAI was 5.3 ± 1.8, mean ASDAS CRP was 3.7 ± 1.01, mean ASDAS ESR was 3.6 ± 1.01. 78% patients had high FC level (more than 100 µg/g), while only 18% patients had an increase of SC level. IBD were diagnosed in 11 cases: 6 (12%) patients with CD and 5 (10%) patients with UC, in the remaining cases (78%) was no intestinal pathology. Only two patients with IBD had a high SC level. SC level was more correlated with ESR (r = 0.5) and CRP (r = 0.5) (p < 0.05) levels, than with FC level (r = 0.4) (p < 0.05).Conclusion. The results have shown that there was currently insuffcient data to assess the possibility of using SC in the diagnosis of IBD in patients with AS. There was a signifcant association between the SC, CRP and ESR, but not fecal calprotectin. Potentially SC may be more representative for systemic inflammation than intestinal inflammation.

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.

Leukocyte Imaging

A prospective study was initiated to compare the clinically proven results concerning localization/extent and activity of inflammatory bowel diseases with those of 111ln-oxine leukocyte imaging. All patients studied were completely examined with barium enema x-ray, clinical and laboratory investigations, and endoscopy with histopathology. A total of 31 leukocyte scans were performed in 15 patients (12 with Crohn’s disease, 3 with ulcerative colitis). The scans were graded by comparing the cell uptake of a lesion (when present) and a bone marrow area providing a count ratio (CR). The inflammatory lesions were correctly localized on 26 leukocyte scans, and in 21 scans the scintigraphically estimated extent of disease was identical to endoscopy. In 5 cases the disease extent was underestimated, 4 scans in patients with relapse of Crohn’s disease were falsely negative, and in one patient with remission truly negative. The scintigraphically assessed disease activity was also in a good agreement with clinical disease activity based on histopathology in all cases. We conclude that leukocyte imaging provides valuable information about localization and activity of inflammatory bowel disease.
