Abstract
The term spondyloarthritis (SpA) encompasses a group of interrelated disorders characterised by the involvement of the musculoskeletal system as well as extra-articular manifestations like acute anterior uveitis, psoriasis and inflammatory bowel diseases (IBD). Likewise, IBD may present with various extra-intestinal manifestations among which those involving the musculoskeletal system, namely peripheral and axial SpA are the most common. The identification of patients with both SpA and IBD is of paramount importance in clinical practice since the coexistence of these two entities has been associated with great disability and decreased quality of life. In order to achieve an early diagnosis of IBD-SpA it is instrumental that rheumatologists seek for gastrointestinal symptoms in SpA patients and likewise that gastroenterologists seek for inflammatory musculoskeletal symptoms in patients with IBD. This narrative review aims at critically appraising the available evidence about SpA occurring in IBD patients versus IBD occurring in patients with SpA and at highlighting similarities and differences between the two scenarios.

Abstract
Axial spondyloarthritis (axSpA) is a chronic inflammatory disease that predominantly affects the axial skeleton and is characterized by inflammatory back pain. While much has been published regarding non-steroidal anti-inflammatory drugs and tumor necrosis factor inhibitors, other classes of medications which leverage alternate molecular mechanisms receive less attention. In this review, we summarize a few of the novel targets in axSpA, review the putative mechanism of action of therapies that focus on these targets, and reference the germane recently completed, ongoing, or proposed randomized controlled clinical trials. The agents addressed include inhibitors of interleukin-23, interleukin-17, janus kinases, granulocyte-macrophage colony-stimulating factor, macrophage migration inhibitory factor, antibodies recognizing T cell receptor beta variable 9 gene positive clones, as well as inhibitors of mitogen-activated protein kinase-activated protein kinase-2.

Abstract
INTRODUCTION The association between spondyloarthritis (SpA) and inflammatory bowel disease (IBD) has been shown in many studies. More recently, with the hypothesis that increased gut inflammation is of etiopathogenic importance in the development of SpA, evaluation of anti-Saccharomyces cerevisiae antibodies (ASCA) has gained increasing relevance. OBJECTIVE To study the status and frequency of ASCA in SpA patients and the association of these biomarkers with the clinical profile. METHODS An observational study was performed including 231 SpA patients treated with biologic therapy. ASCA IgA and IgG levels were determined by micro-enzyme-linked immunosorbent assay. RESULTS Our data showed an increase of ASCA IgA positivity among SpA patients. No relationship was found between ASCA status and the demographic aspects, genetic factors or clinical presentation, except for the association with IBD. CONCLUSION Our study confirms that ASCA IgA are elevated in SpA patients. Although there was no evidence of association with a particular disease phenotype, the existence of higher ASCA levels sustains a close relationship between gut and SpA.

Abstract
Inflammatory bowel disease-associated spondyloarthritis is a systemic disease characterized by the chronic inflammation of both the gastrointestinal tract and the musculoskeletal system. Since inflammatory bowel disease-associated spondyloarthritis has been associated with a significant diagnostic delay, which may lead to poor quality of life and progression of joint damage, efforts to discover new reliable and noninvasive diagnostic biomarkers have been made. We reviewed the state of the art of biomarker research in inflammatory bowel disease-associated spondyloarthritis, showing that to date it has been largely unsatisfactory. Only a few of the biomarkers that have been investigated are likely to enter the clinical practice upon further validation in independent cohorts. The research of new and innovative biomarkers for inflammatory bowel disease-associated spondyloarthritis is warranted.

Abstract
Spondyloarthritis (SpA) is an inflammatory rheumatic disease with diverse clinical presentation. The diagnosis of SpA remains a big challenge in daily clinical practice because of the limitation in specific biomarkers of SpA, more biomarkers are still needed for SpA diagnosis and disease activity monitoring. In the past, SpA was considered predominantly as auto-inflammatory disease vs. autoimmune disease. However, in recent years several researches demonstrated a broad autoantibody response in SpA patients. Study also indicated that mice lack of ZAP70 in T cell develop SpA featured inflammation. These studies indicated the autoimmune features of SpA and gave rise to the potential use of autoantibody in SpA management. In this article, we reviewed recent reports of autoantibodies associated with SpA patients, revealing the autoimmune features of SpA, suggesting the hypothesis that SpA was also an autoimmune disease, studies about the autoimmune features might provide more insights in the pathogenesis of SpA. In addition, as there are two opposite conclusions in the role of anti-CD74 autoantibody in the diagnosis of SpA, we also gave our own data on the diagnostic value of anti-CD74 in Chinese SpA patients. Though our data indicated that anti-CD74 might not be a good biomarker for SpA diagnosis in Asian people, CD74 was still a good molecule target in the research of SpA pathogenesis.

Abstract
Spondyloarthritis is a common type of arthritis which affects mostly adults. It consists of idiopathic chronic inflammation of the spine, joints, eyes, skin, gut, and prostate. Inflammation is often asymptomatic, especially in the gut and prostate. The HLA-B*27 allele group, which presents intracellular peptides to CD8+ T cells, is by far the strongest risk factor for spondyloarthritis. The precise mechanisms and antigens remain unknown. In 1959, Catterall and King advanced a novel hypothesis explaining the etiology of spondyloarthritis: an as-yet-unrecognized sexually acquired microbe would be causing all spondyloarthritis types, including acute anterior uveitis. Recent studies suggest an unrecognized sexually acquired fungal infection may be involved in prostate cancer and perhaps multiple sclerosis. This warrants reanalyzing the Catterall-King hypothesis based on the current literature. In the last decade, many links between spondyloarthritis and fungal infections have been found. Antibodies against the fungal cell wall component mannan are elevated in spondyloarthritis. Functional polymorphisms in genes regulating the innate immune response against fungi have been associated with spondyloarthritis (CARD9 and IL23R). Psoriasis and inflammatory bowel disease, two common comorbidities of spondyloarthritis, are both strongly associated with fungi. Evidence reviewed here lends credence to the Catterall-King hypothesis and implicates a common fungal etiology in prostate cancer, benign prostatic hyperplasia, multiple sclerosis, psoriasis, inflammatory bowel disease, and spondyloarthritis. However, the evidence available at this time is insufficient to definitely confirm this hypothesis. Future studies investigating the microbiome in relation to these conditions should screen specimens for fungi in addition to bacteria. Future clinical studies of spondyloarthritis should consider antifungals which are effective in psoriasis and multiple sclerosis, such as dimethyl fumarate and nystatin.

Abstract
OBJECTIVE The HLA-B27/β2 -microglobulin (β2 m)-transgenic (Tg) rat is a leading model of B27-associated spondyloarthritis (SpA), and the disease is dependent on the presence of intestinal bacteria. Previous studies have shown that adult HLA-B27/β2 m-Tg rats have an altered intestinal microbiota. This study sought to better define the age-dependent changes to both mucosal immune function and dysbiosis in this rat model of SpA. METHODS Intestinal contents were collected from wild-type and HLA-B27/β2 m-Tg rats postweaning (ages 3 and 6 weeks), at disease onset (age 10 weeks), and after the establishment of disease (ages ≥16 weeks). The microbial community structure was determined by 16S ribosomal RNA sequencing and quantitative reverse transcription-polymerase chain reaction (qRT-PCR). Mucosal and systemic Th1, Th17, and Treg cell responses were analyzed by flow cytometry, as was the frequency of IgA-coated intestinal bacteria. Intestinal expression of inflammatory cytokines and antimicrobial peptides (AMPs) was determined by qRT-PCR. RESULTS An inflammatory cytokine signature and elevated AMP expression during the postweaning period preceded the development of clinical bowel inflammation and dysbiosis in HLA-B27/β2 m-Tg rats. An early and sustained expansion of the Th17 cell pool was specifically observed in the cecal and colonic mucosa of HLA-B27/β2 m-Tg rats. Strongly elevated intestinal colonization of Akkermansia muciniphila and an increased frequency of IgA-coated fecal bacteria were significantly associated with expression of HLA-B27 and arthritis development. CONCLUSION HLA-B27/β2 m expression in this rat model renders the host hyperresponsive to microbial antigens from infancy. Early activation of innate immunity and expansion of a mucosal Th17 signature are soon followed by dysbiosis in HLA-B27/β2 m-Tg animals. The pathologic processes of perturbed mucosal immunity and dysbiosis strongly merit further study in both prediseased and diseased populations of patients with SpA.

Abstract
Ankylosing spondylitis (AS) is a debilitating, chronic, rheumatic disease characterized by inflammation and new bone formation resulting in fusion of the spine and sacroiliac joints. Since early treatment is impeded by a delayed diagnosis, it is highly important to find new biomarkers that improve early diagnosis and may also contribute to a better assessment of disease activity, prognosis and therapy response in AS. Because of the absence of rheumatoid factor, AS was long assumed to have a seronegative character and antibodies are thus not considered a hallmark of the disease. However, emerging evidence suggests plasma cells and autoantibodies to be involved in the disease course. In this review, the role of B cells and antibodies in AS is discussed. Furthermore, an overview is provided of antibodies identified in AS up till now, and their diagnostic potential. Many of these antibody responses were based on small study populations and further validation is lacking. Moreover, most were identified by a hypothesis-driven approach and thus limited to antibodies against targets that are already known to be involved in AS pathogenesis. Hence, we propose an unbiased approach to identify novel diagnostic antibodies. The already successfully applied techniques cDNA phage display and serological antigen selection will be used to identify antibodies against both known and new antigen targets in AS plasma. These newly identified antibodies will enhance early diagnosis of AS and provide more insight into the underlying disease pathology, resulting in a more effective treatment strategy and eventually an improved disease outcome.

Abstract
OBJECTIVE The aim of the study was to compare the prevalence of ASCA in spondyloarthrites (SpA) patients and to investigate the association between ASCA status and disease phenotype. METHODS We performed a case-control study including SpA individuals fulfilling the ESSG SpA criteria. The following data were collected for analysis: gender, age, disease duration, clinical or associated features of SpA, treatments, HLAB27 and ASCA status. A control group of patients without SpA was also analyzed. RESULTS A total of 235 patients with SpA and 54 control patients were studied. The median age of SpA patients (53.6% of male patients, 52.2% of HLAB27) was 46.0 [IQR 35.0-57.0] years old. Disease duration was 60.0 [IQR 24.0-156.0] months. Inflammatory bowel diseases were observed in 11% of SpA patients. ASCA positivity was significantly higher in SpA patients than in control patients (25.5% [95% CI 20.1-31.6] (IgG: 9.8%; IgA: 21.7%) vs. 7.4% [95% CI 2.1-17.9], P=0.004). Multivariate analysis revealed that ASCA positivity was associated with peripheral involvement (OR: 3.30 [1.26-8.62], P=0.015), presence of IBD (OR: 3.43 [1.15-10.20], P=0.026), past of present history of uveitis (OR: 4.36 [1.08-17.64], P=0.039) and arthritis (OR: 3.78 [1.57-9.15], P=0.003). CONCLUSION Our results provided evidence that SpA patients had an increased prevalence of ASCA and that ASCA positivity might be associated with a particular phenotype, notably peripheral involvement and uveitis.

Abstract
Patients with Sjogren’s syndrome (SS) frequently have irritable bowel like symptoms (IBS). Some have celiac sprue. The current studies were designed to examine the presence of food hypersensitivities in a population of patients with SS and IBS.
Ten patients were selected from the autoimmune disease clinics at SUNY at Buffalo who had SS and IBS symptoms. Food hypersensitivities were determined by specific IgG ImmunoCAP® assays. Symptoms of abdominal pain, bloating, diarrhea and joint pain were eliminated with dietary restriction of foods to which hypersensitivity was demonstrated. Symptoms recurred with re-institution of offending foods. Resolution of fatigue required elimination of offending foods as well as treatment of underlying metabolic disorders. The presence of IBS in patients with SS should lead to investigation of food hypersensitivities as possible culprits.

Abstract
The last decade has witnessed an explosion of studies evaluating the impact of the human microbiota on a variety of disease states. The microbiota can impact diseases in multiple ways, including through abnormalities in the diversity and contents of the microbiota, as well as by acting as targets of immunologic dysregulation. Herein, evidence that the microbiota in spondyloarthritis is both altered and abnormally targeted by the immune system will be presented.

Abstract
In about 10-15% of patients with inflammatory bowel diseases (IBD) there is no clear definitive differential diagnosis between Crohn's disease (CD) and ulcerative colitis (UC) and the disease is classified as indeterminate colitis. Since pharmacological and surgical treatments differ in CD and UC, establishing a correct diagnosis is critical. The aim of this work was to access the expression profile of proteins involved in colonic inflammation and cancer in samples from CD and UC. For that, colon samples from 24 CD, 21 UC and 10 control patients were processed for immunohistochemistry using anti-phosphorylated RB at Ser(807/811) and anti-β-catenin. Crypts were blinded, analyzed and counted for phosphorylated RB-positive (phospho-RB) cells or scored for positive β-catenin staining. Western blot was used for confirming immuhistochemical results: RB phosphorylation was significantly greater in colon samples from patients with CD compared with UC (p<0.005). In contrast, the expression of β-catenin was significantly increased in UC compared with CD (p<0.005) samples. Phospho-RB and β-catenin are negatively correlated (CC: -0.573; p = 0.001). A positive phospho-RB test yielded high levels of sensitivity, specificity, negative and positive predictive values, and accuracy for the diagnosis of CD against UC. This work indicates that RB phosphorylation and β-catenin nuclear translocation are differently expressed in CD and UC, and provide novel insights into the pathogenic mechanisms of IBD. In particular, rates of phospho-RB-positive cells in mucosal samples emerge as a promising tool for the differential diagnosis of patients with IBD.

Abstract
Introduction Inflammatory bowel disease (IBD) and ankylosing spondylitis (AS) are similar chronic inflammatory diseases whose definitive etiology is unknown. Following recent clinical and genetic evidence supporting an intertwined pathogenic relationship, we conducted a pilot study to measure fecal calprotectin (fCAL) and IBD-related serologies in AS patients. Methods Consecutive AS patients were recruited from a long-term prospectively collected longitudinal AS cohort at Cedars-Sinai Medical Center. Controls were recruited from Cedars-Sinai Medical Center employees or spouses of patients with AS. Sera were tested by ELISA for IBD-associated serologies (antineutrophil cytoplasmic antibodies (ANCA), anti-Saccharomyces cerevisiae antibody IgG and IgA, anti-I2, anti-OmpC, and anti-CBir1). The Bath Ankylosing Spondylitis Disease Activity Index, the Bath Ankylosing Spondylitis Functional Index, and the Bath Ankylosing Spondylitis Radiology Index were completed for AS patients. Results A total of 81 subjects (39 AS patients and 42 controls) were included for analysis. The average age of AS patients was 47 years and the average disease duration was 22 years. AS patients were predominantly male; 76% were HLA-B27-positive. Median fCAL levels were 42 μg/g and 17 μg/g in the AS group and controls, respectively (P < 0.001). When using the manufacturer's recommended cutoff value for positivity of 50 μg/g, stool samples of 41% of AS patients and 10% of controls were positive for fCAL (P = 0.0016). With the exception of ANCA, there were no significant differences in antibody levels between patients and controls. Median ANCA was 6.9 ELISA units in AS patients and 4.3 ELISA units in the controls. Among AS patients stratified by fCAL level, there were statistically significant differences between patients and controls for multiple IBD-associated antibodies. Conclusion Calprotectin levels were elevated in 41% of patients with AS with a cutoff value for positivity of 50 μg/g. fCAL-positive AS patients displayed higher medians of most IBD-specific antibodies when compared with healthy controls or fCAL-negative AS patients. Further studies are needed to determine whether fCAL can be used to identify and characterize a subgroup of AS patients whose disease might be driven by subclinical bowel inflammation.

Abstract
BACKGROUND Because Mycobacterium avium subspecies paratuberculosis (MAP), the etiologic agent of Johne's disease in ruminant, has been identified in the mucosal layer and deeper bowel wall in CD patients, the seroactivity against MAP may define a distinct subset of patients requiring individual treatment. The aim of this study was to assess the performance of anti-MAP antibodies in the diagnostic strategy for CD. METHODS Two hundred seventy-two individuals were included: 81 with CD, 36 with ulcerative colitis, 35 with coeliac diseases and 120 healthy blood donors. Anti-MAP were detected by ELISA using a purified protein derivative from MAP. Anti-Saccharomyces cerevisiae antibodies (ASCA) were detected by indirect immunofluorescence. RESULTS The sensitivity and specificity of anti-MAP and ASCA for CD diagnosis were similar (sensitivity: 0.33 ± 0.10 and 0.31 ± 0.10; specificity: 0.96 ± 0.03 and 0.98 ± 0.02, respectively). A combination of these two tests enabled an increase in sensitivity (0.53 ± 0.10), although specificity remained unchanged (0.95 ± 0.04). No correlation was found between anti-MAP positivity and clinical features such as age at onset and the duration of CD, disease location, or intestinal complications. Conversely, extra-intestinal manifestations of CD were statistically associated with a positivity of anti-MAP (48% vs. 24%, P = 0.028), mostly with respect to arthritis (44.5% vs. 13%, P < 0.002). Interestingly, anti-MAP and ASCA were also found in an active form of coeliac disease. CONCLUSION Our results suggest a complementary role of ASCA and anti-MAP for CD diagnosis and a possible common role of bacteria in small intestinal mucosal damage in CD and coeliac disease.

Abstract
OBJECTIVE Patients with ankylosing spondylitis (AS) can suffer concurrently from inflammatory bowel disease (IBD), as ulcerative colitis (UC) or Crohn's disease (CD). Serological markers have been described to diagnose IBD. We investigated IBD serological markers in AS patients without IBD and whether these antibodies enable differentiating patients with AS and IBD from those without IBD. METHODS Frequencies of perinuclear antineutrophil cytoplasmic antibodies (pANCA), antibodies to the cell-wall mannan of Saccharomyces cerevisiae (ASCA), and antibodies to porin protein C of Escherichia coli (OmpC) were evaluated in 179 patients: 52 with AS, 50 with UC, 51 with CD, and 26 with IBD and AS. Patient groups were matched for age and sex. All AS patients fulfilled the 1984 modified New York criteria. IBD was ascertained by clinical, endoscopic, and microscopic findings. RESULTS In 55% of the AS patients without manifest IBD at least one antibody associated with IBD was observed. pANCA, ASCA (IgA and/or IgG), and OmpC antibodies were found in 21%, 30%, and 19% of the AS patients, respectively. pANCA was more frequently present in AS with concurrent UC than in AS alone (OR 8.2, 95% CI 1.2-55.6), thus being an indicator for UC in AS patients. CONCLUSION Antibodies associated with IBD are detectable in more than half of AS patients without symptoms or signs of IBD. A relatively recent marker in this setting, OmpC antibodies, does not contribute to the differentiation between AS and type of IBD. Presence of pANCA, however, is significantly increased in AS patients who also have UC, and is an indicator to perform endoscopy. These results corroborate a pathophysiological link between AS and IBD.

Abstract
Inflammatory arthritis presents in a variety of diseases, from rheumatoid arthritis to hepatitis. Antibodies to autoantigens or to microbial constituents are commonly associated with these conditions. In some cases, the antibodies have diagnostic and prognostic relevance. It cannot as yet be determined definitively that any of them mediate joint damage, although the evidence from animal models indicates that this mechanism is likely. The purpose of this article is to give an overview of the spectrum of antibodies found in a variety of inflammatory arthritides. The relevant animal models are also discussed.

Abstract
This article reviews the literature concerning rheumatic manifestations of inflammatory bowel disease (IBD), including common immune-mediated pathways, frequency, clinical course and therapy. Musculoskeletal complications are frequent and well-recognized manifestations in IBD, and affect up to 33% of patients with IBD. The strong link between the bowel and the osteo-articular system is suggested by many clinical and experimental observations, notably in HLA-B27 transgenic rats. The autoimmune pathogenic mechanisms shared by IBD and spondyloarthropathies include genetic susceptibility to abnormal antigen presentation, aberrant recognition of self, the presence of autoantibodies against specific antigens shared by the colon and other extra-colonic tissues, and increased intestinal permeability. The response against microorganisms may have an important role through molecular mimicry and other mechanisms. Rheumatic manifestations of IBD have been divided into peripheral arthritis, and axial involvement, including sacroiliitis, with or without spondylitis, similar to idiopathic ankylosing spondylitis. Other periarticular features can occur, including enthesopathy, tendonitis, clubbing, periostitis, and granulomatous lesions of joints and bones. Osteoporosis and osteomalacia secondary to IBD and iatrogenic complications can also occur. The management of the rheumatic manifestations of IBD consists of physical therapy in combination with local injection of corticosteroids and nonsteroidal anti-inflammatory drugs; caution is in order however, because of their possible harmful effects on intestinal integrity, permeability, and even on gut inflammation. Sulfasalazine, methotrexate, azathioprine, cyclosporine and leflunomide should be used for selected indications. In some cases, tumor necrosis factor-α blocking agents should be considered as first-line therapy.

Abstract
Introduction Ankylosing spondylitis (AS) and inflammatory bowel disease (IBD) share similarities and are classified as spondyloarthropathies. In IBD, anti-Saccharomyces cerevisiae antibody (ASCA), anti-I2 (associated with anti-Pseudomonas activity), anti-Escherichia coli outer membrane porin C (anti-OmpC), anti-flagellin (anti-CBir1), and antineutrophil cytoplasmic antibodies (ANCA) possess clinical significance. Because of the overlap between the two conditions, a pilot study was designed to compare the frequency of these antibodies in AS patients compared to normal controls. Methods Serum stored from 80 AS patients and 80 control subjects was available for analysis. ASCA, anti-I2, anti-OmpC, anti-CBir1, and ANCA studies were completed on all serum samples using Enzyme-Linked Immunosorbent Assay (ELISA) methodology. The following analyses were performed: comparison of positivity based on the established values in IBD, median values, the number of subjects in each serology in the 4th quartile of a normal distribution, and the mean quartile sum of all the antibodies. Results There was no difference in positivity rates between AS and control groups with the established IBD values. The median anti-I2 response was significantly higher in AS than in controls (11.78 vs 7.86, p = 0.017). Significantly more AS patients had quartile scores of 4 for the following antibody responses: ASCA IgG (26% vs 13%, p = 0.016, OR = 2.49, CI 1.168 - 5.313), ASCA IgG and IgA (27% vs 12%, p = 0.006, OR = 2.9, CI: 1.342 - 6.264), and anti - I2 (25% vs 14%, p = 0.0424, OR = 2.15, CI: 1.018 - 4.538). The mean quartile sum of the antibody responses was elevated in AS patients when ANCA was excluded (10.526 vs 9.519, p = 0.03). When ANCA was included, this difference lost significance. Conclusions The data from this pilot study points towards mucosal dysregulation as an important pathway in AS. We were able to demonstrate that anti-I2 could play a pathologic role in AS. The elevated mean total antibody response being significant only with ANCA exclusion is consistent with the histopathological evidence that intestinal inflammation in AS is similar to Crohn's disease. To better define the roles of these antibodies in AS, larger studies with more precisely defined patient characteristics are required.

Abstract
Spondyloarthropathies (SpA) are commonly observed extra-intestinal manifestations of both Crohn’s disease (CD) and ulcerative colitis (UC), the two major forms of inflammatory bowel diseases (IBD). However, the immunological link between these two clinical entities is still poorly understood. Several lines of evidence indicate that SpA may originate from the relocation to the joints of the immune process primarily induced in the gut. The transfer of the intestinal inflammatory process into the joints implicates that immune cells activated in the gut-draining lymph nodes can localize, at a certain point of the intestinal disease, either into the gut or into the joints. This is indicated by the overlapping expression of adhesion molecules observed on the surface of intestinal and synovial endothelial cells during inflammation. Moreover bacterial antigens and HLA-B27 expression may be implicated in the reactivation of T cells at the articular level. Finally, accumulating evidence indicates that a T helper 17 cell-mediated immune response may contribute to IBD and IBD-related SpA with a crucial role played by tumor necrosis factor-α in CD and to a lesser extent in UC.

Abstract
Gut inflammation can occur in 30%-60% of patients with spondyloarthropathies. However, the presence of such gut inflammation is underestimated, only 27% of patients with histological evidence of gut inflammation have intestinal symptoms, but subclinical gut inflammation is documented in two-thirds of patients with inflammatory joint disease. There are common genetic and immunological mechanisms behind concomitant inflammation in the joints and intestinal tract. A number of blood tests, e.g. erythrocyte sedimentation rate, orosomucoid, C-reactive protein, and white cell and platelet counts, are probably the most commonly used laboratory markers of inflammatory disease, however, these tests are difficult to interpret in arthropathies associated with gut inflammation, since any increases in their blood levels might be attributable to either the joint disease or to gut inflammation. Consequently, it would be useful to have a marker capable of separately identifying gut inflammation. Fecal proteins, which are indirect markers of neutrophil migration in the gut wall, and intestinal permeability, seem to be ideal for monitoring intestinal inflammation: they are easy to measure non-invasively and are specific for intestinal disease in the absence of gastrointestinal infections. Alongside the traditional markers for characterizing intestinal inflammation, there are also antibodies, in all probability generated by the immune response to microbial antigens and auto-antigens, which have proved useful in establishing the diagnosis and assessing the severity of the condition, as well as the prognosis and the risk of complications. In short, non-invasive investigations on the gut in patients with rheumatic disease may be useful in clinical practice for a preliminary assessment of patients with suspected intestinal disease.

Abstract
AIM The aim of this study was to evaluate, retrospectively, the frequency of anti-Saccharomyces cerevisiae antibodies (ASCA) in patients with primary biliary cirrhosis (PBC). METHODS ASCA, IgG, and IgA, were determined by ELISA in sera of 95 PBC patients; 80 healthy blood donors served as controls. RESULTS The frequency of ASCA (IgG or IgA) was significantly higher in PBC patients than in the control group (24.2% vs 3.7%, P = 0.0001). The frequency of ASCA IgG and ASCA IgA in PBC patients was also significantly higher than that found in the control group (18.9% vs 2.5%, P = 0.0006 and 11.6% vs 1.2%, P = 0.007, respectively). Six patients out of 95 (6.3%) had both ASCA IgG and ASCA IgA; in contrast, none of the control group had both isotypes (P = 0.02). There was no correlation between ASCA levels and mitochondrial autoantibodies (AMA) titres in PBC patients. CONCLUSION We conclude that ASCA are common in patients with PBC.

Abstract
OBJECTIVES Seronegative spondyloarthropathies, especially ankylosing spondylitis (AS), is shown to be associated with inflammatory bowel disease. Anti-Saccharomyces cerevisiae antibodies (ASCA) is a valid serological marker for Crohn's disease. Presence of ASCA is controversial in AS. In this study, we aimed to investigate the prevalence of ASCA in spondyloarthropathies and its relationship with disease activity and severity. METHODS One hundred and seventy-five patients with AS, 47 patients with undifferentiated spondyloarthropathy (uSpA) and 103 healthy controls (HCs) were studied. All patients were questioned for demographic features and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) scores. Radiological damage is assessed by Bath Ankylosing Spondylitis Radiology Index (BASRI) and modified Stroke Ankylosing Spondylitis Spinal Score (mSASSS). ASCA levels were measured with standard ELISA kits. RESULTS There was an overall increased prevalence of ASCA IgA in AS and uSpA compared with HCs (20.6 and 19.1% vs 5.8%, P = 0.0008 and P = 0.02, respectively). No association was observed between ASCA positivity and erythrocyte sedimentation rate, C-reactive protein levels and BASDAI scores. However, ASCA-positive patients had higher BASRI scores [median BASRI: 7 (2-12) vs 6 (2-12); P = 0.037]. Although not reaching significance, they also had reduced chest expansion and higher Bath Ankylosing Spondylitis Functional Index (BASFI) scores. ASCA-positive AS patients also required anti-tumour necrosis factor therapy more frequently (P = 0.006). CONCLUSIONS ASCA IgA seems to be more prevalent in AS and uSpA. ASCA can also be a marker of radiological damage and a more severe course in AS.

Abstract
OBJECTIVE To evaluate, retrospectively, the frequency of anti-Saccharomyces cerevisiae antibodies (ASCA) in patients with coeliac disease. MATERIAL AND METHODS ASCA, IgG and IgA were determined by ELISA in sera of 238 coeliac patients. The patients were divided into three groups: group I - 125 untreated patients; group II - 42 patients under a strict gluten-free diet (GFD); and group III - 71 patients who did not comply with a GFD. Sera of 80 healthy blood donors served as controls. RESULTS The frequency of ASCA (IgG or IgA) was significantly higher in untreated coeliac patients than in the control group (27.2% versus 3.7%, p=10(-5)). In 238 coeliac patients, the frequency of ASCA was significantly higher in adults than in children (35.4% versus 21.1%, p=0.01). In group III, the frequency of ASCA was significantly higher in adults than in children (60% versus 26.1%, p=0.004). In 238 coeliac patients, ASCA IgG were significantly more frequent than ASCA IgA in both children (19% versus 6.3%, p=0.001) and adults (33.3% versus 12.5%, p=5.10(-4)). In children, ASCA IgG were negative in group II and positive in 20% of group I (p=0.01). In adults, the frequency of ASCA IgG was also significantly lower in group II than in group I (9.5% versus 34%, p=0.03). CONCLUSIONS A high frequency of ASCA has been found in coeliac patients. The frequency of ASCA was not statistically different between patients with successful adherence to GFD and healthy controls.

Abstract
AIM: Anti-Saccharomyces cerevisiae antibodies (ASCA), anti-nuclear associated anti-neutrophil antibodies (NANA) and antibodies to exocrine pancreas (PAB), are serological tools for discriminating Crohn’s disease (CrD) and ulcerative colitis (UC). Like CrD, coeliac disease (CoD) is an inflammatory bowel disease (IBD) associated with (auto) antibodies. Performing a multicenter study we primarily aimed to determine the performance of ASCA, NANA and PAB tests for IBD diagnosis in children and adults, and secondarily to evaluate the prevalence of these markers in CoD.
METHODS: Sera of 109 patients with CrD, 78 with UC, 45 with CoD and 50 healthy blood donors were retrospectively included. ASCA, NANA and PAB were detected by indirect immunofluorescence (IIF).
RESULTS: ASCA+/NANA- profile displayed a positive predictive value of 94.2% for CrD. Detection of ASCA was correlated with a more severe clinical profile of CrD and treatment of the disease did not influence their serum levels. ASCA positivity was found in 37.9% of active CoD. PAB were found in 36.7% CrD and 13.3% CoD patients and were not correlated with clinical features of CrD, except with an early onset of the disease. Fifteen CrD patients were ASCA negative and PAB positive.
CONCLUSION: ASCA and PAB detected by IIF are specific markers for CrD although their presence does not rule out a possible active CoD. The combination of ASCA, NANA and PAB tests improves the sensitivity of immunological markers for CrD. Repeating ASCA, NANA, and PAB testing during the course of CrD has no clinical value.

Abstract
Between 5 and 10% of cases of ankylosing spondylitis (AS) are associated with inflammatory bowel disease (IBD), either Crohn's disease or ulcerative colitis. A much larger percentage of AS patients have subclinical gut inflammation manifested either by endoscopic findings or by histology. The association with HLA-B27 is less strong in IBD-associated AS than in idiopathic AS, and there is evidence for an association between gut inflammation in AS with the Crohn's-disease-related CARD15 mutations. Despite the different genetics, the immunopathology suggests common inflammatory pathways in gut and joint inflammation in AS, and in gut inflammation in AS and IBD. Although this observation is of interest to unravel the pathophysiology of the disease, systematic screening of AS patients by ileocolonoscopy is not indicated in the absence of gut symptomatology as only a small proportion of AS patients with subclinical gut inflammation will develop overt IBD over time. Treatment of AS associated with IBD with non-steroidal anti-inflammatory drugs (NSAIDs) is problematic because of concerns of potential re-activation of IBD by NSAIDs. Major advances have been made in recent years with the establishment of anti-tumour necrosis factor (TNF) therapy in AS, the other spondyloarthritides and IBD. Anti-TNF agents are of particular relevance to AS patients with concomitant IBD who are at risk of exacerbation of the underlying bowel disease when treated with NSAIDs. In IBD, infliximab, unlike etanercept, is effective in treating clinical symptoms, inducing and maintaining remission, and mucosal healing. Adalimumab appears to be effective in treating both AS and IBD; however, official approval is pending. Currently, infliximab is the drug of choice for the treatment of patients with active AS associated with IBD.

The prevalence of extraintestinal manifestations and HLA association in patients with inflammatory bowel disease. Rheumatol Int 2005; 26:663-8.

Abstract
To determine the prevalence, clinical and radiological characteristics of spondyloarthropathy (SpA) in patients with inflammatory bowel disease (IBD), to assess the association between HLA B27 and B51 and the extraintestinal symptoms and to evaluate whether IBD is associated with Behçet's disease (BD). One hundred and sixty-two consecutive adult patients with established diagnosis of IBD as either Crohn's disease (CD) or ulcerative colitis (UC) were evaluated. All the patients including those previously diagnosed with or without SpA had a complete rheumatologic examination and they were evaluated according to the European Spondyloarthropathy Study Group (ESSG) criteria for SpA and The International Study Group for Behçet's disease criteria for BD. The demographic and clinical data were recorded on a standardized form. The radiographies were obtained in all the patients and computed tomography (CT) was performed in the patients with suspected pelvic radiographies and/or low back pain in the physical examination. Radiological evaluation was made according to the Modified New York criteria. HLA B27, B51 and anti-neutrophile cytoplasmic antigen (ANCA) were searched in all the patients. Of the 162 patients with IBD (mean age 41.48+/-11.63 years, male 60, female 102), 78 were CD and 84 were UC. The mean of the IBD duration was 54.92+/-50.32 months and SpA duration was 20.63+/-34.37 months. The prevalence of SpA and AS in IBD was 45.7 and 9.9%, respectively. Frequencies of SpA and AS, the difference between UC and CD were not significant. Spondylitis, enthesitis, peripheral arthritis, oral ulcer and uveitis were not different between UC and CD, but erythema nodosum was found significantly more common in the CD patients compared with UC patients (P=0.005). The duration of IBD and SpA was similar in both groups. As the IBD duration increased, the prevalence of SpA development decreased (rr=0.991, P=0.009). Of the IBD patients, 13.6% were asymptomatic for musculoskeletal manifestations of SpA and their sacroiliac radiographies and CTs showed grade 2 sacroiliitis. HLA B27, B51 and ANCA positivities were not different between the patients with UC and CD. HLA B27 was significantly more common in the patients with sacroiliitis, spondylitis, enthesitis, peripheral arthritis, erythema nodosum, uveitis (P<0.001) and oral ulcer (P=0.025). BD was diagnosed in none of the patients. ANCA positivity was found to be related with the presence of erythema nodosum and uveitis (P=0.001 and P=0.005). The prevalence of SpA and AS is higher in the prospectively evaluated patients with radiological studies than those in the previously published studies. There is a high prevalence of asymptomatic sacroiliitis in IBD. An early diagnosis of inflammatory arthritis in IBD patients may prevent a disability due to SpA and AS.

Abstract
In this paper, the ample experimental, clinical, genetic, histopathologic, and immunologic evidence for an important role of the gut in the pathogenesis of spondylarthropathy (SpA) and for an overlap between SpA and Crohn's disease is reviewed. These data suggest that SpA and Crohn's disease should be scientifically and clinically considered as distinct phenotypes of common immune-mediated inflammatory disease pathways rather than as separate disease entities. Classification, diagnosis, and therapy based on pathophysiologic insights is likely to become superior to an approach based exclusively on signs and symptoms, as evidenced by the recent evolution in treatment of SpA by tumor necrosis factor-a blockade.

Abstract
Potential implications of antibody markers in Crohn's disease: Diagnostic markers, alone or in conjunction with other antibodies? Delineation of clinical phenotypes? Markers of disease behaviour? Markers of (genetic) susceptibility? Identification of genetically homogenous subgroups? Bridge between basic science and clinic? The exact role of serum antibodies in inflammatory bowel disease remains a matter of ongoing debate. Although a direct implication in the disease pathogenesis is unlikely, their diagnostic potential in cases of an undetermined colitis or in defining clinical phenotypes in Crohn's disease has been shown in several studies. Serum antibodies might also be helpful in predicting the disease behaviour and are thus valuable tools in the choice of medical or surgical therapy.
