The link between ankylosing spondylitis and inflammatory bowel disease is unclear, however it is hypothesized that there is a causal link between the inheritance of a human leukocyte antigen B27 allele and the development of inflammatory bowel disease symptoms in ankylosing spondylitis patients. Research articles assessing the relationship between ankylosing spondylitis, inflammatory bowel disease and the human leukocyte antigen B27 antigen were collected from the PubMed database. Patients expressing the human leukocyte antigen B27 allele have a demonstrated predisposition to developing symptoms of inflammatory bowel disease and sacroiliitis in ankylosing spondylitis. However, human leukocyte antigen B27 is considered to be just a contributing factor in the disease, as interleukin-23, natural killer cells, and alterations to the microbiome have also demonstrated an active role in the development of symptoms. More longitudinal studies using larger cohorts are needed to further substantiate a direct causal relationship between ankylosing spondylitis and inflammatory bowel disease.

Abstract Background Human leukocyte antigen-G (HLA-G) has been proposed to influence susceptibility to inflammatory bowel disease (IBD). Therefore, the genetic association between HLA-G alleles and two clinical phenotypes of IBD (ulcerative colitis [UC] and Crohn’s disease [CD]) was evaluated in Iraqi patients. A case-control study was performed on 50 UC and 50 CD patients and 100 healthy controls (HC). Three HLA-G alleles (G*01:03, G*01:04, and G*01:05N) were determined using sequence-specific polymerase chain reaction assay followed by product digestion with restriction endonucleases (Hinf-I, BseR-I, and PpuM-I, respectively). Results The G*01:03 allele was not detected in IBD patients (UC and CD) or HC, while G*01:04 and G*01:05N alleles showed polymorphic frequencies. The allele G*01:04 was significantly associated with susceptibility to UC (odds ratio [OR] = 2.55; 95% confidence interval [CI] = 1.27–5.13; corrected probability [pc] = 0.018) and CD (OR = 4.45; 95% CI = 2.11–9.41; pc < 0.001). The allele G*01:05N was also associated with increased risk of UC (OR = 4.17; 95% CI = 1.32–13.21; pc = 0.032) and CD (OR = 4.75; 95% CI = 1.53–14.78; pc = 0.014). These associations were more pronounced in IBD (UC + CD), and a significantly increased risk for IBD was found with the alleles G*01:04 (OR = 3.32; 95% CI = 1.86–5.95; pc < 0.001) and G*01:05N (OR = 4.46; 95% CI = 1.59–12.47; pc = 0.008). A stratification of IBD patients according to some demographic and clinical characteristics revealed that frequencies of both alleles showed no significant differences between the subgroups of patients in each stratum. Soluble HLA-G was not influenced by HLA-G alleles in patients or HC. UC was an exception, and the presence of G*01:04 allele was associated with a significantly higher mean of soluble HLA-G compared to patients without the allele (189.6 ± 24.0 vs. 168.6 ± 27.2 ng/mL; p = 0.033). Conclusion This study indicated that HLA-G*01:04 and HLA-G*01:05N alleles may influence susceptibility to UC and CD in Iraqi patients.

Low Incidence

The precise etiology and mechanisms of inflammatory bowel disease (IBD) are still unclear. Nevertheless, several concepts are gaining acceptance and constitute the basis for a better understanding of its pathogenesis and for improved therapy. The association of Crohn’s disease (CD) and ulcerative colitis (UC) with ‘western’ lifestyle is well recognized, and is considered a reason for the increasing frequency of CD and UC in countries with previously low incidence. Proposed linkages of CD and UC with particular human leukocyte antigen haplotypes suggest a genetic predisposition, but no uniform or consistent patterns have emerged. Similarly, the study of susceptibility or disease markers has not offered reproducible results. The search for specific infectious agents is being pursued, and the measles virus is presently considered a possible culprit. A true explosion has occurred in the area of animal models, and a large number of chemically or genetically induced experimental colitides are at hand. Immunological factors continue to dominate the bulk of basic research in IBD. This area is vast and complex, and autoantibodies, immune, epithelial and mesenchymal cells, lipid mediators, cytokines, neuropeptides and oxygen metabolites are under investigation. Finally, other factors whose role in IBD is uncertain, including smoking and possible abnormalities of intestinal permeability or mucus composition, continue to receive attention. These extensive and varied efforts are yielding some profits, and new forms of therapy are being devised. Based mostly on studies of soluble mediators, a number of novel immunosuppressive and highly specific blocking agents are being developed and undergoing clinical trials.

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.

An 18-year-old female with ankylosing spondylitis developed fever, abdominal pain and diarrhea on two occasions after starting sulphasalazine therapy. Flexible sigmoidoscopy revealed pseudomembranous colitis; fecal cultures were positive forClostridium difficile; andC difficiletoxin assay was positive. Despite the frequent use of sulphasalazine in the management of inflammatory bowel disease, this complication has been apparently rare. Clinicians should be wary of the onset of diarrhea in patients receiving sulphasalazine, whether for inflammatory bowel disease or other conditions.
