Newly Diagnosed Crohn's Disease Patients in India and Israel Display Distinct Presentations and Serological Markers: Insights from Prospective Cohorts. J Clin Med 2022; 11:jcm11236899. [PMID: 36498474 PMCID: PMC9737641 DOI: 10.3390/jcm11236899] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 11/12/2022] [Accepted: 11/20/2022] [Indexed: 11/24/2022] Open
Abstract
Background: Crohn’s disease (CD) incidence is rising in India. However, features of newly diagnosed patients with CD in this population are largely unknown. The Indo-Israeli IBD GastroEnterology paRtnership (TiiiGER) aimed to investigate differences in presentation among patients with newly diagnosed CD in India and Israel, and to explore phenotype−serotype correlations. Methods: A prospective observational cohort study of consecutive adults (>18 years) conducted in two large referral centers in India and Israel (2014−2018). Clinical data, an antiglycan serological panel, and 20 CD-associated genetic variants were analyzed. Outcomes: complicated phenotype at diagnosis and early complicated course (hospitalizations/surgeries) within 2 years of diagnosis. Results: We included 260 patients (104, Indian (65.4%, male; age, 37.8); 156 Israeli (49.4%, male; 31.8, age)). Median lag time from symptoms onset to diagnosis was 10.5 (IQR 3−38) vs. 3 (IQR 1−8) months in Indian vs. Israeli patients (p < 0.001). Complicated phenotype at diagnosis was observed in 48% of Indian and 30% of Israeli patients (p = 0.003). Complicated phenotype was associated with higher anti-Saccharomyces cerevisiae antibody (ASCA) seropositivity rate among Israeli patients (p < 0.001), but not among Indian patients. Antiglycan serology did not correlate with the tested genetic variants. Early complicated course occurred in 28 (18%) Israeli and 13 (12.5%) Indian patients. The time from diagnosis to complication was comparable (log rank p = 0.152). Antiglycan serology did not correlate with a complicated early course in either cohort. Conclusions: There are significant differences in patients presenting with newly diagnosed CD in India and Israel, including phenotype and distinct biomarkers at diagnosis. These differences suggest different genetic and environmental disease modifiers.

Abstract
Background/Aims We evaluated whether anti-Saccharomyces cerevisiae antibody (ASCA) titers are associated with diagnostic findings, disease activity, Paris classification phenotypes, and persistence after infliximab (IFX) treatment in children with Crohn’s disease (CD). We also investigated the role of ASCA as a predictor of mucosal healing (MH) and clinical remission (CR). Methods This study included 61 CD patients aged 19 years or younger who were diagnosed and treated between September 2010 and January 2019 and followed for at least 1 year. ASCA was regularly measured at the diagnosis of CD and at least 1 year after IFX therapy. Results The average follow-up period was 3.8±3.4 years (range, 1.0 to 7.2 years). Regression analysis showed that the ASCA titer was the only factor associated with Simple Endoscopic Score for Crohn's Disease (SES-CD) or CR among all the parameters. In patients who had achieved MH (SES-CD=0), ASCA immunoglobulin G (IgG) was not associated with MH, but in patients without MH, ASCA IgG was associated with SES-CD (p=0.005) and CR (p<0.001). The cutoff value of ASCA IgG in patients with CR was 21.8 units. However, there was no difference in the relapse rate between the ASCA IgG-positive and -negative groups during the follow-up period. Conclusions In patients who have not achieved MH, ASCA IgG is closely related to mucosal damage and CR. Unlike Western studies, ASCA IgG may be more helpful in predicting prognosis than immunoglobulin A in Korean patients, but it is not an appropriate indicator to predict the relapse of CD.

Abstract
Hidradenitis suppurativa (HS) is a rare, debilitating skin disease characterized by the presence of recurrent tender subcutaneous nodules that develop into abscesses and fistulae. Isolated perineal Crohn's disease (CD) is unusual, diagnosis can be difficult, and distinction from HS is a challenge for the gastroenterologist. The aim of this work was to determine the criteria that distinguish perineal CD from perineal HS. Four patients with isolated perineal CD and three with perineal HS were included. Rectal or skin biopsies of all CD patients showed granulomas. No granulomas were found for HS. Fistulae were present in 4/4 CD, extended to the anal canal. All patients with HS had gluteal abscesses. They were bilateral in all cases, superficial. Perineal lesions management should involve a multidisciplinary approach in order to make an accurate diagnosis and ultimately to give the best and most effective treatment.

Abstract
BACKGROUND AND AIM Proteinase 3 antineutrophil cytoplasmic antibodies (PR3-ANCAs) are well-known serological markers for granulomatosis with polyangiitis, but their role as serological markers for inflammatory bowel disease remains uncertain. The present study aimed to evaluate the diagnostic and clinical role of PR3-ANCAs as markers for inflammatory bowel disease. METHODS Using a new methodology with chemiluminescence enzyme immunoassay, serum PR3-ANCA titers were assessed in 102 patients with ulcerative colitis (UC), 67 patients with Crohn's disease (CD), 44 controls with other intestinal diseases, and 66 healthy controls. Associations with clinical data were investigated. The diagnostic role of PR3-ANCAs was evaluated by receiver operating characteristic analysis. RESULTS Proteinase 3 antineutrophil cytoplasmic antibody titers were significantly higher in patients with UC than in those with CD patients, patients with intestinal diseases (intestinal controls), and healthy controls (all P < 0.001). Receiver operating characteristic analysis demonstrated an area under the curve of 0.85 (95% confidence interval: 0.83-0.87) and showed that the manufacturer's cutoff value (3.5 U/mL) had a sensitivity of 39.2% and specificity of 96.6% for UC. There was a significant difference between PR3-ANCA-positive and PR3-ANCA-negative patients with regard to disease duration (P < 0.05) and disease severity (P < 0.01). CONCLUSIONS Proteinase 3 antineutrophil cytoplasmic antibodies were significantly more prevalent in patients with UC than in those with CD and controls. Our results suggested the role of PR3-ANCAs as serological markers for aiding in diagnosing UC and evaluating disease severity. Further prospective studies are needed across multiple populations of patients and ethnic groups.

The utility of apoptosis inhibitor of macrophages as a possible diagnostic marker in patients with Crohn's disease. BMC Gastroenterol 2017; 17:40.

Abstract
Background Apoptosis inhibitor of macrophages (AIM) was initially identified as an apoptosis inhibitor that supports the survival of macrophages against various apoptosis-inducing stimuli, and AIM produced by macrophages may contribute to the pathogenesis of inflammatory bowel diseases (IBDs). However, there have been no reports on the kinetics of AIM in IBD and the impact of AIM on the pathogenesis of IBD. In this study, we aimed to investigate the diagnostic utility of levels of AIM and their correlation with the activity of Crohn’s disease (CD) and IBD. Methods We used an enzyme-linked immunosorbent assay (ELISA) to examine AIM serum levels in 16 healthy subjects and 90 patients with inflammatory bowel diseases, namely 39 with CD and 51 with ulcerative colitis (UC), as well as 17 patients with Behcet’s disease (BD) as intestinal disease controls. We compared serum AIM levels among groups and examined whether there were correlations between serum AIM levels and disease activity and type. We also performed immunohistochemical staining of AIM in intestinal tissues of patients with CD. Results Serum AIM levels were significantly higher in patients with CD than in patients with UC, BD, and controls (3.27 ± 2.14, 1.88 ± 1.43, 2.34 ± 1.37, and 2.13 ± 0.64 μg/ml, respectively; P < 0.01). There was no difference in serum AIM levels before and after treatment in patients with CD. However, in these patients the diagnostic rate using AIM was better than that based on anti-Saccharomyces cerevisiae antibodies. AIM was expressed in macrophages that were positive for CD14, CD16, or both in the intestinal tissues of patients with CD. Conclusions AIM is a novel biomarker of CD that can distinguish CD from UC or BD. It is suggested that AIM may contribute to intestinal inflammation by inhibiting the apoptosis of macrophages.

Abstract
The epidemiology, genetics, and clinical manifestations of Crohn's disease (CD) vary considerably among geographic areas and ethnic groups. Thus, identifying the characteristics of Korean CD is important for establishing management strategies appropriate for Korean patients. Since the mid-2000s, many studies have investigated the characteristic features of Korean CD. The incidence and prevalence rates of CD have been increasing rapidly in Korea, especially among the younger population. Unlike Western data, Korean CD shows a male predominance and a lower proportion of isolated colonic disease. Perianal lesions are more prevalent than in Western countries. Genome-wide association studies have confirmed that genetic variants in TNFSF15, IL-23R, and IRGM, but not ATG16L1, are associated with CD susceptibility in the Korean population. Studies of the associations between genetic mutations and the clinical course of CD are underway. Although it has been generally accepted that the clinical course of Korean CD is milder than that in Western countries, recent studies have shown a comparable rate of intestinal resection in Korean and Western CD patients. An ongoing nationwide, hospital-based cohort study is anticipated to provide valuable information on the natural history and prognosis of Korean CD in the near future.

Abstract
BACKGROUND Various noninvasive tests have been studied to screen for patients with Crohn's disease (CD), and were found to have limited accuracy and sensitivity, particularly in Asian populations. The aim of our study was to explore the possible diagnostic utility of antibodies to the CD peptide (ACP) in patients with CD. METHODS In a multicenter study using enzyme-linked immunosorbent assay, serum ACP levels were determined in 196 patients with CD, 210 with ulcerative colitis, 98 with other intestinal diseases, 132 with other inflammatory diseases, and 183 healthy controls. and then examined for correlation to clinical variables. The diagnostic utility of ACP was evaluated by receiver operating characteristics analysis and compared with anti-Saccharomyces cerevisiae antibodies (ASCA). RESULTS ACP levels were significantly elevated in the CD patients, but not in the other groups that included UC, other intestinal diseases, other inflammatory diseases and the healthy controls. Among these other groups, ACP levels were not significantly different. In the CD patients, ACP had a higher sensitivity and specificity (63.3 and 91.0 %, respectively) than ASCA (47.4 and 90.4 %). ACP levels were negatively associated with disease duration, but not with CDAI, disease location, or medical treatment. CONCLUSIONS ACP, a newly proposed serologic marker, was significantly associated with CD and was highly diagnostic. Further investigation is needed across multiple populations of patients and ethnic groups, and more importantly, in prospective studies.

Abstract
BACKGROUND Mannose-binding lectin (MBL) is a pattern-recognition molecule and an important component of the innate defense system. Anti-Saccharomyces cerevisiae antibody (ASCA) is a well known serologic marker of Crohn's disease (CD). This study aimed to investigate the association between MBL, ASCA, and clinical features in Korean CD patients. METHOD Two hundred and eighty-three well-characterized CD patients were included. MBL concentrations, serum IgG and IgA concentrations of ASCA were determined by ELISA. Low MBL concentrations were defined as serum MBL concentrations <500 ng/ml. RESULT Low MBL concentrations were observed in 41 CD patients (14.5%). No differences in MBL concentrations were detected according to the age at diagnosis, behavior, or the location of patients with CD. MBL concentrations and the frequency of low MBL concentrations did not differ according to ASCA positivity. The presence of perianal involvement (p=0.043), younger age at diagnosis (p=0.021), and intestinal surgery (p=0.047) were more frequently associated with ASCA positive patients. CONCLUSION MBL concentration is not associated with clinical features of CD patients or ASCA positivity. ASCA positivity is associated with a severe clinical course in Korean CD patients.

Abstract
INTRODUCTION A hyper-responsive adaptive immunologic response to a variety of microbial antigens has been described in Crohn's disease (CD) patients and elevated levels of a number of antibodies have been identified in the sera of CD patients. To date, the serological profiles of an Irish CD population have not been characterized. OBJECTIVES The aim of this study is to determine the serological profile of Irish patients with CD. Second, we aim to assess the correlation, if any, between serological profile and disease phenotype within this cohort. METHODS A total of 179 consecutive adults with CD attending a specialist inflammatory bowel disease clinic at a university hospital were recruited. Blood samples were taken and sera were analysed for the expression of pANCA and Crohn's related antibodies. RESULTS pANCA was present in 47/179 (26.3%), anti-OmpC antibodies were present in 49/179 (27.4%), anti-Saccharomyces cervisiae (ASCA) in 64/179 (35.75%), ASCA IgA in 56/179 (31.28%) and ASCA IgG in 37/179 (20.67%), and anti-CBir antibodies in 97/179 (54.18%). The presence of ASCA IgA (P=0.031), ASCA IgG (P=0.007) and anti-CBir antibodies (P=0.003) were all significantly associated with small bowel involvement. Anti-OmpC, ASCA IgA and anti-CBir antibodies' positivity were all associated with complicated disease behaviour, whereas ANCA positivity was associated with inflammatory disease. CONCLUSION Our study supports previous findings of an association between serological profiles and disease behaviour and a corresponding association with increased need for surgery. In this genetically homogenous Irish CD study group, the levels of specific antibody responses to commensal gut flora are lower than reported previously in other European and American populations.

Abstract
AIM: To study serological antibodies in Caucasians and Asians, in health and inflammatory bowel disease (IBD), in Australia and Hong Kong (HK).
METHODS: Anti-glycan antibodies [anti-chitobioside (ACCA), anti-laminaribioside (ALCA)], and anti-mannobioside (AMCA), anti-Saccharomyces cervisiae (gASCA); and atypical perinuclear anti-neutrophil cytoplasmic antibody (pANCA) were tested in IBD patients, their unaffected relatives, and healthy controls in Australia and HK (China). Antibody status (positive or negative) and titre was compared between subjects of different geography, ethnicity and disease state.
RESULTS: Ninety subjects were evaluated: 21 Crohn’s disease (CD), 32 ulcerative colitis (UC), 29 healthy controls, and 8 IBD patient relatives. Forty eight subjects were Australian (29 Caucasian and 19 ethnic Han Chinese) and 42 were from HK (all Han Chinese). Caucasian CD patients had a significantly higher antibody prevalence of gASCA (67% vs 3%, P < 0.001), ALCA (44% vs 6%, P = 0.005), and AMCA (67% vs 15%, P = 0.002), whereas HK CD patients had a higher prevalence of only AMCA (58% vs 25%, P = 0.035), when compared with UC and healthy subjects in both countries. Caucasian CD had significantly higher gASCA prevalence (67% vs 0%, P < 0.001) and titre (median 59 vs 9, P = 0.002) than HK CD patients. Prevalence and titres of ALCA, ACCA and AMCA did not differ between CD in the two countries. Presence of at least one antibody was higher in Caucasian than HK CD patients (100% vs 58%, P = 0.045). pANCA did not differ between countries or ethnicity.
CONCLUSION: Serologic CD responses differ between HK Asian and Australian Caucasian patients. Different genetic, environmental or disease pathogenic factors may account for these differences.

Abstract
BACKGROUND Ileal intubation is being increasingly performed at colonoscopy and has in turn lead to an increasingly recognized subgroup of patients-those with mild terminal ileal inflammation, an entity that we have coined isolated active ileitis (IAI). The aims of this study were to define the natural history of IAI and determine if IAI shares a similar genetic and serologic profile with Crohn's disease (CD). METHODS Patients with IAI were identified from our institution's histopathology and endoscopy databases. Cases attended for repeat colonoscopy and blood were analyzed for the expression of antineutrophil cytoplasmic antibody, anti-OmpC, anti-Saccharomyces cerevisiae antigen (ASCA) IgA, ASCA IgG, and anti-CBir antibodies and NOD2 genotyping. Age and sex-matched healthy controls, CD, and UC cases were also recruited. RESULTS Sixty-three patients with IAI were recruited. There was no significant difference in the prevalence of antibodies between IAI cases and healthy controls for antineutrophil cytoplasmic antibody, OmpC, ASCA IgA, or ASCA IgG. The presence of all 5 antibodies was significantly higher in the CD group than the IAI group, P < 0.05. There were 28.6% of CD cases that carried one or more NOD2 variants, compared to 26.2% of the IAI cohort and 6.1% of healthy controls. Forty-three cases underwent follow-up ileocolonoscopy. Six of 43 cases (14%) had definite CD. CONCLUSIONS A majority of IAI cases developed persistent symptoms and terminal ileal abnormalities; however, only 14% developed classical, histological, or radiological features of CD. Although patients with IAI have a low level of seropositivity, similar to healthy controls, they do share an excess of NOD2 mutations with CD cases.

Abstract
BACKGROUND Recent studies suggested that anti-Saccharomyces cerevisiae antibody (ASCA) status was associated with diagnostic findings, stratified classification phenotypes, disease activity and clinical course of Crohn's disease (CD). However, the relationship between ASCA status and phenotypes of CD remains controversial in these studies. AIMS The purpose of this study was to evaluate whether ASCA status is associated with the phenotypes and the risk of surgery in diverse populations in CD. METHODS We conducted a meta-analysis of studies assessing the association of ASCA status with phenotypes and risk of surgery in CD. Three independent reviewers undertook data extraction. We pooled odds ratios separately for the cohort and case-control studies. RESULTS We identified ten cohort studies (n = 2,365) and 14 case-control studies (n = 1,887) that investigated the association of ASCA status with phenotypes and risk of surgery in CD. The meta-analysis of the cohort studies showed significant association between the ASCA-positive status and higher risk of early-onset age (OR 2.25, 95 % CI 1.41-3.57, P < 0.001), ileal involvement disease (1.70, 1.05-2.77, P = 0.03), complicated disease behavior (2.09, 1.71-2.57, P < 0.001), perianal disease (1.49, 1.14-1.94, P = 0.004), and risk for surgery (1.61, 1.29-2.01, P < 0.001). Meta-analysis of the case-control studies also showed a significantly higher risk in ileal involvement disease (1.77, 1.25-2.49, P = 0.001), complicated disease behavior (2.13, 1.70-2.68, P < 0.001), perianal disease (1.96, 1.38-2.78, P < 0.001), and risk for surgery (1.71, 1.17-2.49, P = 0.005), except for the early-onset age (1.16, 0.80-1.69, P = 0.44). CONCLUSIONS This meta-analysis indicated that positive ASCA status is a risk factor for early-onset age, ileal involvement, complicated behavior, perianal disease and requirement for surgery in CD.

Abstract
The diagnosis of inflammatory bowel disease (IBD) is traditionally based on a combination of clinical, endoscopic, histological, and radiological criteria. However, further testing is needed in cases of diagnostic uncertainty and in predicting disease course. This systematic review focuses on the potential for 10 serological antibodies to fill these roles: pANCA, ASCA, anti-OmpC, anti-CBir1, anti-I2, ALCA, ACCA, AMCA, anti-L, and anti-C. We discuss their prevalence in IBD and health; their role in disease diagnosis and risk stratification; their stability over time; their presence in unaffected relatives; their association with genetic variants; and differences across ethnic groups. Serological antibodies have some role in primary diagnosis and in differentiating between Crohn's disease and ulcerative colitis. In indeterminate colitis, preoperative measurement of serological antibodies can help to predict the likelihood of complications among patients undergoing pouch surgery. The combined presence and magnitude of a large panel of antibodies appear to be of value in predicting disease progression. There is currently insufficient evidence to recommend the use of antibody testing to predict responses to treatment or surgery in patients with IBD.

Diagnostic utility of anti-Saccharomyces cerevisiae antibody (ASCA) and Interferon-γ assay in the differential diagnosis of Crohn's disease and intestinal tuberculosis. Clin Chim Acta 2011; 412:1527-32.

Abstract
BACKGROUND Differential diagnosis of Crohn's disease (CD) from intestinal tuberculosis (ITB) is challenging. Anti-Saccharomyces cerevisiae antibody (ASCA) is a specific serological marker for CD and INF-gamma assay (QuantiFERON-TB gold test, QFT) is a good supplementary diagnostic tool for ITB. We evaluated the clinical usefulness of ASCA and QFT for differential diagnosis of CD from ITB in Korean adults. METHODS A total of 147 patients suspected to have ITB or CD were prospectively enrolled from 13 hospitals. ASCA IgG and IgA serum titers were measured by ELISA, and the QFT test was also performed. RESULTS Thirty-two of 72 (44.4%) patients with CD were ASCA positive (titer >25U) compared to 10 of 75 ITB patients (13.3%) and 3 of 20 healthy controls (15%) (p<0.01). The QFT test was positive in 7 patients with CD (9.7%) and 50 patients with ITB (66.6%) (p<0.01). In cases which ASCA positive/QFT negative, the sensitivity, specificity, positive predictive value, and negative predictive value for the diagnosis of CD were 44.4%, 96.0%, 91.4%, and 64.3%, respectively. CONCLUSION ASCA is a useful diagnostic tool for CD in Korea, where ITB is prevalent. In particular, when ASCA is combined with QFT, effective differential diagnosis of CD from ITB is possible.

Abstract
There is an increasing interest in the discovery of new inflammatory bowel disease (IBD) biomarkers able to predict the future patterns of disease and to help in diagnosis, treatment, and prognosis. A biomarker is a substance that can be measured biologically and is associated with an increased risk of the disease. Biomarkers can be a genetic testing factor or proteins in biological samples such as serum, plasma, and cellular subpopulations. All of them should be studied to find out their utility in the management of IBD. Ulcerative colitis and Crohn's disease are relapsing and remitting chronic IBDs characterized by a global immune defect. The gold standard of their diagnosis is histological evaluation performed during endoscopic procedures. Several studies have focused on the identification and combination of less invasive diagnostic serum biomarkers. Nowadays, diagnostic serum tests are not able either to determine whether and when the relapse will occur once the disease is in remission state or to select a patient phenotype more responsive to a specific therapy and more susceptible to different types of complication. In this review we analyze and report the current understanding in IBD biomarkers and discuss potential future biomarkers and new developments of proteomics, such as subproteomics, as an innovative approach for the classification of patients according to their pattern of protein expression.

Abstract
Prescription drugs and surgery are two common medical therapies for Crohn's disease (CD), an inflammatory bowel disease that affects the GI tract. Unfortunately, certain drugs can cause serious side effects, and surgeries must often be repeated. No diet has been established to alleviate the pain and suffering of CD patients. This is curious given the fact that a higher prevalence of food sensitivities exist in this population of patients, and enteral nutrition is not only the first-line of therapy in Japan, but a known research method used to place the majority of CD patients into remission. Although not all patients respond equally to diet, many simply remove symptom-provoking foods, such as dairy, wheat, corn and certain fruits and vegetables. We suggest assisting these patients in their self-assessment of irritating and symptom-provoking foods by educating them in the use of a food-symptom diary followed by a customized elimination diet trialed for 2-4 weeks to determine if there is any benefit to the individual patient.

Abstract
Crohn's disease is suggested to result from a microbially triggered immune-mediated autoimmune process, involving mainly the terminal ileum and ileo-caecal junction. Klebsiella pneumoniae shares certain molecular structures present in pullulanase pulA and pulD secretion enzymes with various self-antigens present in collagens and HLA-B27 molecules, respectively. A link exists between high dietary starch intake and the growth of intestinal microflora, involving especially Klebsiella microbes. Increased exposure to Klebsiella in the gut as the result of high starch intake would lead to high production of antiKlebsiella antibodies as well as autoantibodies to the cross-reactive self-antigens with the resultant inflammation at the pathological sites. Eradication of these microbes from the gut in patients with Crohn's disease with the use of low-starch diet and antibacterial agents as well as immunomodulatory measures could be beneficial in the management of this disease.

Abstract
Inflammatory bowel disease is a chronic inflammatory disease of the gastrointestinal tract. Its main clinical manifestations are abdominal pain and diarrhea. Its etiology is complicated. Immune system is very important. Following factors, such as intestinal environment, immune cells, human leukocyte antigens, antibodies, anti- laminaribioside antibody, anti-chitobioside antibody IgA, cytokines, cell adhesion molecules, NO and NF-κB, play a key role in the pathogenesis of inflammatory bowel disease. Inflammatory bowel disease is related to all these factors. This paper reviews the possible role of these immune factors in the pathogenesis of inflammatory bowel disease.
