Abstract
Diagnosing inflammatory bowel disease (IBD) can often be challenging, and differentiating between Crohn's disease and ulcerative colitis can be particularly difficult. Diagnostic procedures for IBD include laboratory tests, endoscopy, pathological tests, and imaging tests. Serological and stool tests can be easily performed in an outpatient setting and provide critical diagnostic clues. Although endoscopy is an invasive procedure, it offers essential diagnostic information and allows for tissue biopsy and therapeutic procedures. Video capsule endoscopy and device-assisted enteroscopy are endoscopic procedures used to evaluate the small bowel. In addition to endoscopy, magnetic resonance imaging, computed tomography, and ultrasound (US) are valuable tools for small bowel assessment. Among these, US is noninvasive and easily utilized, making its use highly practical in daily clinical practice. Endoscopic biopsy aids in the diagnosis of IBD and is crucial for assessing the histological activity of the disease, facilitating a thorough evaluation of disease remission, and aiding in the development of treatment strategies. Recent advances in artificial intelligence hold promise for enhancing various aspects of IBD management, including diagnosis, monitoring, and precision medicine. This review compiles current procedures and promising future tools for the diagnosis of IBD, providing comprehensive insights.

Abstract
Crohn's disease (CD), a chronic inflammatory bowel disorder, manifests in various phenotypes, with fistulizing perianal CD (CD-PAF) being one of its most severe phenotypes. Characterized by fistula formation and abscesses, CD-PAF impacts 17% to 34% of all CD cases and with a significantly deleterious impact on patient's quality of life, while increasing the risk for anorectal cancers. The pathogenesis involves a complex interplay of genetic, immunological and environmental factors, with cytokines such as tumor necrosis factor-alpha (TNF-α) and transforming growth factor-beta (TGF-β) playing pivotal roles. Diagnostic protocols require a multi-disciplinary approach including colonoscopy, examination under anesthesia and magnetic resonance imaging. In terms of treatment, biologics alone often prove inadequate, making surgical interventions such as setons and fistula surgeries essential. Emerging therapies such as mesenchymal stem cells are under study. The South Asian context adds layers of complexity, including diagnostic ambiguities related to high tuberculosis prevalence, healthcare access limitations and cultural stigma toward perianal Crohn's disease and ostomy surgery. Effective management necessitates an integrated, multi-disciplinary approach, especially in resource-constrained settings. Despite advances, there remain significant gaps in understanding the disease's pathophysiology and a dearth of standardized outcome measures, underscoring the urgent need for comprehensive research.

Clinical and magnetic resonance imaging spectrum of complex perianal fistulizing Crohn's disease: A cohort study from northern India. Indian J Gastroenterol 2023; 42:668-676. [PMID: 37548863 DOI: 10.1007/s12664-023-01399-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Accepted: 05/15/2023] [Indexed: 08/08/2023]
Abstract
BACKGROUND Fistulizing perianal Crohn's disease (CD) is a debilitating condition associated with significant morbidity and reduction in the quality of life. Magnetic resonance imaging (MRI) of the pelvis is the preferred imaging modality for the comprehensive assessment of the perianal fistula. There is a paucity of data from India on the MRI spectrum of complex perianal fistula in CD. METHODS A single-centre cross-sectional analysis of patients with fistulizing perianal CD, who underwent pelvic MRI between January 2020 and December 2021, was performed. The clinical (age, sex, disease duration, disease location and behavior, disease activity [Perianal Disease Activity Index, PDAI] and treatment received) and radiological (number and location of fistulae, extensions, number and location of internal and external openings, fistula activity, presence or absence of perianal abscess and associated proctitis) characteristics of complex perianal fistula (defined according to the American Gastroenterological Association classification) were recorded. RESULTS Of total 175 patients with CD who attended the gastroenterology clinic during the study period, 27 (15.42%) (mean age 42±15.5 years, 62.96% females and median disease duration four years) had complex perianal fistula and were included in the analysis. The mean PDAI was 5.48±2.53. The median Van Assche Index was 17 (interquartile range [IQR] 13-19). A majority (96.29%) of the fistulae were trans-sphincteric and four (14.81%) fistulae extended into the supralevator space. All fistulae were active on MRI. Concomitant perianal abscess and proctitis were seen in 59.26% (n=16) and 62.96% (n=17) of patients, respectively. Combination therapy with biologics and antibiotics/immune-suppressants were the most commonly prescribed medical therapy. Six (22.22%) patients underwent combined medical and surgical (non-cutting seton, fistulectomy, fecal diversion) treatment. CONCLUSION The cumulative risk of the development of fistulizing perianal CD in a northern Indian cohort was similar to the western populations. Complex perianal fistulae were predominantly trans-sphincteric and commoner in females. MRI evaluation is pivotal for the delineation of fistula anatomy, assessment of disease extent and activity and the evaluation of concomitant perianal abscess and other complications.

Abstract
Background and Aim Crohn's disease is an inflammatory condition that affects the gastrointestinal (GI) system. This study aimed to determine the prevalence of upper gastrointestinal Crohn's disease (UGICD) and compare its features to non-UGICD types. Methods We conducted a systematic search in the databases PubMed, Web of Science, Scopus, and Google Scholar. The heterogeneity of prevalence estimates was examined, subgroup analyses were carried out, and meta-analyses were conducted using random-effects modeling. Prognostic data were qualitatively reviewed and combined. Results Two-thousand nine-hundred and forty studies were retrieved and 32 studies were included in the final analysis. Pooled prevalence of UGICD was 15% (CI: 11-18%) among 14 509 patients. UGICD prevalence did not show any significant increase with time (P = 0.45). The most prevalent (38%, CI: 30-47%) behavior of UGICD was B1 (nonstricturing-nonpenetrating), while the most common concurrent location was L3 (ileocolon) with a prevalence of 47% (CI: 34-59%). UGICD patients had higher stricturing phenotype (B2) compared to non-UGICD (0.38 vs 0.30; P = 0.03). There was no significant difference in the prevalence of UGICD between patients classified according to the Montreal or Vienna classification. Stricturing phenotype was more common among Asian patients compared to Western patients (0.44 vs 0.24; P < 0.001). UGICD was a risk factor for surgery and drug therapy and was associated with an aggressive course of the disease and more resections. Pooled prevalence of UGICD was 15%. Conclusion Nonstricturing-nonpenetrating type was the most prevalent UGICD. UGICD patients had more complications and worse outcomes compared to non-UGICD patients.

Abstract
PURPOSE To build computed tomography enterography (CTE)-based multiregional radiomics model for distinguishing Crohn's disease (CD) from intestinal tuberculosis (ITB). MATERIALS AND METHODS A total of 105 patients with CD and ITB who underwent CTE were retrospectively enrolled. Volume of interest segmentation were performed on CTE and radiomic features were obtained separately from the intestinal wall of lesion, the largest lymph node (LN), and region surrounding the lesion in the ileocecal region. The most valuable radiomic features was selected by the selection operator and least absolute shrinkage. We established nomogram combining clinical factors, endoscopy results, CTE features, and radiomic score through multivariate logistic regression analysis. Receiver operating characteristic (ROC) curves and decision curve analysis (DCA) were used to evaluate the prediction performance. DeLong test was applied to compare the performance of the models. RESULTS The clinical-radiomic combined model comprised of four variables including one radiomic signature from intestinal wall, one radiomic signature from LN, involved bowel segments on CTE, and longitudinal ulcer on endoscopy. The combined model showed good diagnostic performance with an area under the ROC curve (AUC) of 0.975 (95% CI 0.953-0.998) in the training cohort and 0.958 (95% CI 0.925-0.991) in the validation cohort. The combined model showed higher AUC than that of the clinical model in cross-validation set (0.958 vs. 0.878, P = 0.004). The DCA showed the highest benefit for the combined model. CONCLUSION Clinical-radiomic combined model constructed by combining CTE-based radiomics from the intestinal wall of lesion and LN, endoscopy results, and CTE features can accurately distinguish CD from ITB.

Abstract
BACKGROUND The impact of diagnostic delay on the clinical course of inflammatory bowel disease (IBD) remains uncertain. AIM To perform a systematic review of time to diagnosis and the impact of delayed diagnosis on clinical outcomes in Crohn's disease (CD) and ulcerative colitis (UC). METHODS We searched EMBASE and Medline from inception to 30th November 2022 for studies reporting diagnostic interval, from symptom onset to IBD diagnosis. We calculated the median, interquartile range (IQR) and pooled weighted median, of median diagnostic intervals of eligible studies. We defined delayed diagnosis as individuals above the 75th centile of longest time to diagnosis in each study. Using random effects meta-analysis, we pooled odds ratios (ORs) with 95% confidence intervals (CI) for studies reporting clinical outcomes, according to delayed diagnosis. RESULTS One hundred and one studies representing 112,194 patients with IBD (CD = 59,359; UC = 52,835) met inclusion criteria. The median of median times to diagnosis was 8.0 (IQR: 5.0-15.2) and 3.7 months (IQR: 2.0-6.7) in CD and UC, respectively. In high-income countries, this was 6.2 (IQR: 5.0-12.3) and 3.2 months (IQR: 2.2-5.3), compared with 11.7 (IQR: 8.3-18.0) and 7.8 months (IQR: 5.2-21.8) in low-middle-income, countries, for CD and UC respectively. The pooled weighted median was 7.0 (95% CI: 3.0-26.4) and 4.6 (95% CI: 1.0-96.0) months, for CD and UC respectively. Eleven studies, representing 6164 patients (CD = 4858; UC = 1306), were included in the meta-analysis that examined the impact of diagnostic delay on clinical outcomes. In CD, delayed diagnosis was associated with higher odds of stricturing (OR = 1.88; CI: 1.35-2.62), penetrating disease (OR = 1.64; CI: 1.21-2.20) and intestinal surgery (OR = 2.24; CI: 1.57-3.19). In UC, delayed diagnosis was associated with higher odds of colectomy (OR = 4.13; CI: 1.04-16.40). CONCLUSION Delayed diagnosis is associated with disease progression in CD, and intestinal surgery in both CD and UC. Strategies are needed to achieve earlier diagnosis of IBD.

Abstract
BACKGROUND The extent of diagnostic delay in inflammatory bowel disease (IBD) is incompletely understood. We aimed to understand the extent of diagnostic delay of IBD in adults and identify associations between patient or healthcare characteristics and length of delay. METHODS Articles were sourced from EMBASE, Medline and CINAHL from inception to April 2021. Inclusion criteria were adult cohorts (18 ≥ years old) reporting median time periods between onset of symptoms for Crohn's disease (CD), ulcerative colitis (UC) or IBD (i.e. CD and UC together) and a final diagnosis (diagnostic delay). Narrative synthesis was used to examine the extent of diagnostic delay and characteristics associated with delay. Sensitivity analysis was applied by the removal of outliers. RESULTS Thirty-one articles reporting median diagnostic delay for IBD, CD or UC were included. After sensitivity analysis, the majority of IBD studies (7 of 8) reported a median delay of between 2 and 5.3 months. From the studies examining median delay in UC, three-quarters (12 of 16) reported a delay between 2 and 6 months. In contrast, three-quarters of the CD studies (17 of 23) reported a delay of between 2 and 12 months. No characteristic had been examined enough to understand their role in diagnostic delay in these populations. CONCLUSIONS This systematic review provides robust insight into the extent of diagnostic delay in IBD and suggests further intervention is needed to reduce delay in CD particularly. Furthermore, our findings provide a benchmark value range for diagnostic delay, which such future work can be measured against.

Abstract
Crohn's disease (CD) usually affects younger individuals but delayed-onset disease is not uncommon. We studied the epidemiology, demographic profile, and clinical characteristics of patients with delayed-onset CD (disease onset >50 years) and compared them with CD in younger individuals (disease onset 20-40 years) in a tertiary care center in India. The presenting symptoms, site of involvement, and treatment profile were similar, except for weight loss, which was more often noted in young-onset CD. However, granulomatous inflammation on mucosal biopsy was twice as common in young-onset compared to delayed-onset CD. As it is thus seen less often in delayed-onset CD, this may lead to a potential delay in diagnosis and treatment.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is a chronic inflammatory disorder affecting the gastrointestinal tract. The etiology of this alarming condition is multifactorial. A Recently increasing trend in IBD is noted in our country. OBJECTIVE The present study was designed with the main objective to assess the incidence and to identify the associated risk factors including demographic, geographical areas, and dietary patterns of IBD population of Northern of Karnataka viz. Hubli-Dharwad city. METHODS A retrospective investigation was conducted on a cohort of 226 patients with a working diagnosis of IBD and those who were admitted between 2015 to 2019 the department of gastroenterology, SDMCMS&H. The diagnosis of IBD was made based on clinical, radiological, endoscopic, and histopathologic findings. The patients were categorized into IBD and those who have symptoms suggestive of IBD but did not fit into the diagnostic criteria into, non-IBD groups. The data about of on demography, diet patterns, and laboratory parameters were recorded. RESULTS Among 226 patients enrolled in this study 2015-2019, IBD was confirmed in 54 Ulcerative colitis - 44 (19.46%), Crohn's disease - 10 (4.42%) patients with varying distribution of disease among different age groups and both genders, Ulcerative colitis (UC) [M: F: 28 (63.6%): 16 (36.4%)] and Crohn's disease (CD) [M: F: 07 (70.0%):03 (30.0%)]. Dietary pattern and other habitats had no significant contribution to illness and its symptoms. Urban (U) and Rural (R) divide was UC [U: R: 32 (72.7%): 12 (27.3%)], CD [U:R:07(70.0%):03(30.0%)] maintained. CONCLUSION Incidence of IBD was high with UC as compared to CD. The incidence of IBD among patients presenting with symptoms suggestive of IBD is 19.46% with UC being major as compared to CD (4.42%). Male predominant patterns of IBD incidences were noted. Year by year increasing trend in disease burden was observed. The Dietary pattern has no direct correlation with IBD disease prevalence and incidences.

Abstract
BACKGROUND AND AIM Inflammatory bowel disease (IBD) is emerging in the newly industrialized countries of South Asia, South-East Asia, and the Middle East, yet epidemiological data are scarce. METHODS We performed a cross-sectional study of IBD demographics, disease phenotype, and treatment across 38 centers in 15 countries of South Asia, South-East Asia, and Middle East. Intergroup comparisons included gross national income (GNI) per capita. RESULTS Among 10 400 patients, ulcerative colitis (UC) was twice as common as Crohn's disease (CD), with a male predominance (UC 6678, CD 3495, IBD unclassified 227, and 58% male). Peak age of onset was in the third decade, with a low proportion of elderly-onset IBD (5% age > 60). Familial IBD was rare (5%). The extent of UC was predominantly distal (proctitis/left sided 67%), with most being treated with mesalamine (94%), steroids (54%), or immunomodulators (31%). Ileocolic CD (43%) was the commonest, with low rates of perianal disease (8%) and only 6% smokers. Diagnostic delay for CD was common (median 12 months; interquartile range 5-30). Treatment of CD included mesalamine, steroids, and immunomodulators (61%, 51%, and 56%, respectively), but a fifth received empirical antitubercular therapy. Treatment with biologics was uncommon (4% UC and 13% CD), which increased in countries with higher GNI per capita. Surgery rates were 0.1 (UC) and 2 (CD) per 100 patients per year. CONCLUSIONS The IBD-ENC cohort provides insight into IBD in South-East Asia and the Middle East, but is not yet population based. UC is twice as common as CD, familial disease is uncommon, and rates of surgery are low. Biologic use correlates with per capita GNI.

A combination of circulating microRNA-375-3p and chemokines CCL11, CXCL12, and G-CSF differentiate Crohn's disease and intestinal tuberculosis. Sci Rep 2021; 11:23303.

Abstract
Differentiation of Crohn’s disease (CD) from intestinal tuberculosis (ITB) is a big challenge to gastroenterologists because of their indistinguishable features and insensitive diagnostic tools. A non-invasive biomarker is urgently required to distinguish ITB/CD patients particularly in India, a TB endemic region, where CD frequency is increasing rapidly due to urbanization. Among the three differentially expressed miRNAs obtained from small RNA transcriptomic profiling of ileocaecal/terminal ileal tissue of ITB/CD patients (n = 3), only two down-regulated miRNAs, miR-31-5p, and miR-215-5p showed comparable data in qRT-PCR. Out of which, only miR-215-5p was detectable in the patient’s plasma, but there was no significant difference in expression between ITB/CD. On the other hand, miR-375-3p, the pulmonary TB specific marker was found in higher amount in the plasma of ITB patients than CD while reverse expression was observed in the ileocaecal/terminal ileal tissues of the same patients. Next, using Bioplex pro-human cytokine 48-plex screening panel, only three chemokines, Eotaxin-1/CCL11, SDF-1α/CXCL12, and G-CSF have noted significantly different levels in the serum of ITB/CD patients. ROC analysis has revealed that compared to a single molecule, a combination of miR-375-3p + Eotaxin-1/CCL11 + SDF-1α /CXCL12 + G-CSF showed a better AUC of 0.83, 95% CI (0.69–0.96) with 100% specificity and positive predictive value while sensitivity, negative predictive value, and accuracy were 56%, 69%, and 78% respectively in distinguishing ITB from CD. This study suggests that a combination of plasma markers shows better potential in differentiating ITB from CD than a single marker and this panel of markers may be used for clinical management of ITB/CD patients.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is increasingly diagnosed in South Asia. This survey by the Tamil Nadu Chapter of the Indian Society of Gastroenterology (TNISG) documents the demography, clinical profile, and therapeutic practices related to IBD in Tamil Nadu. METHODS TNISG members from 32 institutions completed an online cross-sectional questionnaire on IBD patients from March 2020 to January 2021. RESULTS Of 1295 adult IBD patients, 654 had Crohn's disease (CD), 499 ulcerative colitis (UC), and 42 IBD-unclassified (IBD-U). CD and UC showed a unimodal age distribution. A total of 55% were graduates or postgraduates. A positive family history was noted in 30, other risk factors were uncommon. In CD, the pattern of involvement was ileocolonic (42.8%), ileal (34.7%), colonic (18.9%), and upper gastrointestinal (3.5%); while in UC, disease was characterized as extensive (44.9%), left-sided (41.7%), or proctitis (13.4%). Perineal disease, perianal fistulae, and bowel obstruction were noted in 4.3, 14.0, and 23.5%, respectively, of CD. The most widely used drugs were mesalamine, azathioprine, and corticosteroids. Surgery was undertaken in 141 patients with CD and 23 patients with UC. Of the 138 patients with pediatric IBD (≤16 years), 23 were characterized as very early onset IBD (VEO-IBD), 27 as early-onset, and 88 as adolescent IBD. VEO-IBD were more likely to have a positive family history of IBD and were more likely to have perineal disease and to have the IBD-U phenotype. Among pediatric IBD patients, corticosteroids, mesalamine, and azathioprine were the most commonly used medications, while 25 pediatric patients received biologics. CONCLUSION This study provides important information on demography, clinical profile, and treatment practices of IBD in India.

Abstract
Crohn's disease (CD) is a chronic destructive inflammatory bowel disease that affects young people and is associated with significant morbidity. The clinical spectrum and disease course of CD are heterogeneous and often difficult to predict based on the initial presentation. In this article, changes in the disease location, behavior, clinical course during long-term follow-up, and predictive factors are reviewed. Generally, four different patterns of clinical course are discussed: remission, stable disease, chronic relapsing disease, and chronic refractory disease. Understanding the long-term disease course of CD is mandatory to reveal the underlying pathophysiology of the disease and to move toward a more optimistic disease course, such as remission or stability, and less adverse outcomes or devastating sequelae.

Abstract
BACKGROUND A 26-year-old male had a history of frequent bowel movements, mushy stool with mucus and loss of 25 kg body weight in 6 months was diagnosed as a case of inflammatory bowel disease (IBD). The patient did not respond to routine and standard treatment for IBD. His condition was steadily deteriorating, and he was in a very precarious state when he reported to us. METHODS Upon laboratory investigation by using IS900 specific PCR [which is specific for Mycobacterium avium subspecies paratuberculosis (MAP)], the blood and stool samples were found negative. However, the presence of low titer MAP-antibodies by indigenous ELISA were found followed by detection of the typical acid-fast MAP bacilli (with 3 + or 4 + grade) microscopically. The MAP stool culture was positive after 6 months incubation. The biotyping by IS1311 specific polymerase chain reaction restriction enzyme (PCR-RE) confirmed infection with 'Indian Bison Type Genotype', a dominant biotype infecting the domestic livestock population of India. Standard anti-MAP therapy was initiated under supervision of the treating physician. The drug of choice in prescribed treatment regimen included Isoniazid (5 mg/kg), Rifampicin (10 mg/kg), Ethambutol (15-25 mg/kg) once a day for 24 weeks and Clarithromycin (250 mg)/Levofloxacin (250 mg) twice a day for 6 weeks. RESULTS Following treatment, the patient started improving progressively with reduction in bowel movement frequency and gained body weight with an enhanced appetite propensity. Upon follow-up of the patient after 1 year of treatment, stool-microscopy and stool-culture were found negative for MAP. Till the recent past, the patient was further monitored for disease relapse, if any. CONCLUSIONS This patient has experienced a complete resolution of IBD using a combination of anti-MAP antibiotics. The initial detection of heavy shedding of acid-fast MAP bacilli and typical colony morphology with its characterization obtained from culturing of stool sample indicated the infection of MAP. Interestingly, the present case is one more example of the linkage of demonstrable MAP infection treated with anti-MAP therapy in the presence and then absence of disease in the human host.

Abstract
Inflammatory bowel disease (IBD) in recent times is causing a significant healthcare burden as both ulcerative colitis and Crohn's disease (CD) require lifelong therapy and constant monitoring. The current review highlights the concerns in a country like India with special reference to the changing trends of IBD, risk attribution and the financial issues. Indian immigrants behave like residential Indians, whereas their children show IBD prevalence similar to the West, highlighting the role of environmental triggers. However, the environmental and genetic factors in Indians with IBD are not well understood. Men appear to be more frequently affected than women in India. The disease severity is milder in the patients, both males and females, but the risk for colorectal cancer (CRC) is similar to the West. The incidence of paediatric IBD is on the rise. The major burden of IBD in the Indian subcontinent at present is in children, adolescents and teens. Cost towards the management of complications, non-adherence to treatment, differentiating tuberculosis from CD and finally screening for CRC in patients with IBD are the points to ponder in the Indian scenario.

Abstract
Inflammatory bowel diseases (IBD), including ulcerative colitis (UC) and Crohn's disease (CD), are chronic inflammatory disorders of the gastrointestinal tract caused by interactions between genetic, environmental, immunological, and microbial factors. While the incidence and prevalence of IBD in Asian populations were relatively lower than those in Western countries, they appear to be gradually increasing. A Westernized diet, high socioeconomic status, improvement of hygiene, and development of vaccination could affect the increases in IBD incidence and prevalence in Asian countries. This review describes the latest trends in the incidence and prevalence of IBD in Asia. Studying the epidemiology of IBD in Asia may unravel the etiopathogenesis of and risk factors for IBD.

Abstract
Background and Aim Crohn's disease (CD) and intestinal tuberculosis (ITB) have similar symptomatology and overlapping features on imaging, endoscopy, and histopathology. It is important to differentiate ITB from CD to initiate correct medical management. This prospective study aimed to characterize imaging features on computed tomography enteroclysis/enterography (CTE) that help in differentiating ITB from CD. Methods A total of 300 consecutive patients who underwent CTE with the suspicion of small bowel diseases were evaluated. CTE findings were documented on a detailed "CTE case record form" and were correlated with other investigations like endoscopy, histopathological and microbiological examination, and improvement on empirical therapy to arrive at a final diagnosis. Only confirmed cases of ITB/CD were included for further analysis. Results Final diagnoses revealed that 61 patients had ITB, 24 had CD, 90 patients had a final diagnosis not related to ITB/CD, and 125 had no bowel-related diseases. The sensitivity of CTE (ITB vs CD, 90.2 vs 91.6%) was higher than the sensitivity of ileocolonoscopy (ITB vs CD, 87 vs 83.3%). A homogenous pattern of bowel wall thickening and confluent bowel involvement were significantly more common in ITB. Stratified bowel wall thickening with mucosal hyperenhancement, skip lesions in the bowel, and a comb sign were significantly more common in CD. Stratified bowel wall enhancement with an intervening layer of fat was specifically (P < 0.001) seen in patients with CD, and necrotic (P = 0.002) and calcified (P = 0.055) lymph nodes were specifically seen in patients with ITB. Conclusion We propose a systematic approach to the radiological differentiation of ITB from CD.

Abstract
Inflammatory bowel disease (IBD) is increasing in prevalence in resource-limited settings in Asia. Although the prevalence of IBD is lower in these settings than in high-income countries, the high disease burden due to large population size is projected to overtake that of high-income countries in the near future. Unique challenges exist for diagnosing and managing IBD in Asia. On one hand, the inadequate disease awareness in physicians and the general population, the scarcity of diagnostic services, the infectious mimics of IBD (specifically intestinal tuberculosis), and the widespread use of empirical antibiotics and antitubercular therapy pose diagnostic challenges. On the other hand, the absence of a centralised health-care delivery system or universal health insurance, the high cost of therapy, limited access to biologics, and the high risk of opportunistic infections with immunosuppressive therapy present therapeutic challenges. The high probability of tuberculosis reactivation often precludes biological therapy because Asia is highly endemic for tuberculosis and has a high prevalence of latent tuberculosis. Current screening strategies are often ineffective in ruling out latent tuberculosis. Hence, management strategies are often modified according to these challenges. This Series paper discusses the challenges in the diagnosis and management of IBD in resource-limited settings in Asia.

Abstract
BACKGROUND The prevalence and clinical features of inflammatory bowel disease (IBD) vary among different racial and ethnic groups. The aim of this study was to compare the clinical and phenotypic features of Crohn's disease (CD) and ulcerative colitis (UC) in South Asian patients living in the United States with those of a white cohort. METHODS The demographic, clinical, and phenotypic characteristics of 73 South Asian patients (31 CD and 42 UC) who presented initially to our tertiary referral center from 2012 to 2016 and had subsequent follow-up were retrospectively compared with those of 408 consecutive white patients (245 CD and 163 UC). RESULTS South Asian IBD patients were significantly more likely to have UC (58.0% vs 40.0%; P = 0.005) than white patients. South Asians with CD were less likely to have a family history of IBD (9.7% vs 26.9%; P = 0.037) and required fewer CD-related surgeries (22.5% vs 46.1; P = 0.012). South Asians were also less likely to be active or former smokers in both the CD (P = 0.004) and UC (P = 0.020) groups. South Asians with UC had a higher incidence of Clostridium difficile infection compared with white patients (19.0% vs 8.6%; P = 0.050). CONCLUSIONS A cohort of South Asian patients with IBD were more likely to have UC and had differing family and tobacco risk factors, requirements for surgery, and Clostridium difficile infection rates as compared with white patients.

Long-term outcomes in perianal fistulizing Crohn's disease in a resource-limited setting: A cohort analysis. Indian J Gastroenterol 2020; 39:435-444. [PMID: 33040321 DOI: 10.1007/s12664-020-01054-7] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2020] [Accepted: 05/12/2020] [Indexed: 02/04/2023]
Abstract
BACKGROUND Perianal fistula is one of the most challenging complications of Crohn's disease (CD). We aimed to describe treatment response with surgical and medical therapies, and long-term complications. METHODS We retrospectively analyzed records of patients with perianal fistulizing CD who were prospectively followed from January 2005 to December 2018. RESULTS Among 807 patients, 81 (10%) had perianal fistula and 65 were included in the final analysis. The mean age of presentation was 27.4 ± 10.3 years, and 78.5% were males with a median duration of follow-up of 45 (IQR, 24-66) months. 75.4% (n = 49) had complex fistulae. 55.4% (n = 36) of patients received multiple courses (> 5 courses) of antibiotics. Complete response rates with immunomodulators, fistula surgery, biologicals, and diversion were 25%, 42.8%, 39.5%, and 45.4%, respectively. The relapse rate was highest after fistula surgery (52.6%). 44.6% of patients received medical (immunomodulators-21 and biologicals-8) whereas 46.1% received surgery as the first-line therapy. The absence of perianal abscess was associated with complete fistula closure. One patient developed malignancy and 4 (6.1%) died at the end of follow-up. Among the patients (n = 28) who received biologicals, TB reactivation occurred in one patient (3.5%). CONCLUSION Medical therapy should be offered as first-line therapy, and immunomodulators can be considered when patients cannot afford biologicals. Surgery offers temporary improvement and is associated with high relapse rates. Absence of perianal abscess predicts long-term complete fistula closure.

Abstract
The prevalence of Crohn disease (CD) is increasing in Asia, but data from Southeast Asian population are scarce.The databases of 2 university-based national tertiary referral centers located in Bangkok, Thailand, were retrospectively reviewed for adult patients diagnosed with CD during January 2000 to December 2017. Disease characteristics, diagnosis, treatment, and outcomes were described and compared between the 2000 to 2009 cohort (cohort A) and the 2010 to 2017 cohort (cohort B).One hundred eighty-two patients (mean age: 46.4 years, 50% male) with 993 patient-years of follow-up were included. Thirteen percent had a history of intestinal resection, but were not diagnosed until disease recurrence. Another 6% were diagnosed at the time of first surgery. There was no improvement in diagnostic proficiency between cohorts. Mesalamine, corticosteroids, thiopurines, and biologics were prescribed in 75.8%, 81.3%, 84.6%, and 13.7% of patients, respectively (P > .05 between cohorts). Notably, thiopurines were started earlier in cohort B. Median time to the start of thiopurines was 6.2 and 1.65 months in cohort A and B, respectively (P < .01). However, the cumulative 5-year rates of disease behavior progression (P = .43), hospitalization (P = .14), and bowel surgery (P = .29) were not significantly different between cohorts. Subgroup analysis including only patients who required thiopurines showed the early use of thiopurines to be associated with lower risk of intestinal surgery after diagnosis (hazard ratio: 0.30, 95% confidence interval: 0.11-0.85).Early disease recognition and early introduction of immunomodulators may prevent long-term complications and reduce unnecessary surgery in CD.

The role of dietary polyphenols in inflammatory bowel disease: A possible clue on the molecular mechanisms involved in the prevention of immune and inflammatory reactions. J Food Biochem 2020; 44:e13369.

Abstract
Inflammatory bowel disease (IBD) is one of the major complications of the gastrointestinal tract, characterized by chronic inflammation, which disturbs the quality of life of the affected individuals. Genetic predisposition, immune, inflammatory, and enzyme-mediated signaling cascades are the primary mechanisms involved in the pathogenesis of the disease. Currently, the treatment strategy involves the maintenance of remission and induction of inflammation by anti-inflammatory agents and immune suppressants. Polyphenol-containing diets, including fruits and vegetables of regular use, possess anti-inflammatory, and antioxidant potential through the inhibition of major contributing pathways to IBD. This review discusses the role of these dietary polyphenols in downregulating the major signaling cascades in IBD. Our review encourages the development of nutritional strategies to improve the efficiency of current therapies for IBD and reduce the risks of side effects associated with conventional therapy. PRACTICAL APPLICATIONS: At present, almost every third person in society is under stress and having chronic disorders like diabetes, arthritis, allergy, cardiovascular disease, IBD, etc. This insists on the direct/indirect role of changes in the lifestyle for such deterioration in society. This review would emphasize the medicinal value of polyphenols present in fruits and vegetables for chronic inflammatory disorders. This concept portrays the food components which have the potential to promote health, improve general well-being, and reduce the risk of IBD. We propose to add fruits with bioactive polyphenols in the regular diet to help in preventing the immune-mediated intestinal chronic inflammatory syndrome and reduce the risks of colorectal cancer development.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is emerging in the developing world but phenotypic data are limited. We aimed to describe the phenotype, clinical presentation, disease behavior, and treatments of IBD in a large cohort in India. METHODS All persons presenting to the Asian Institute of Gastroenterology in Hyderabad, India since 2004 with a confirmed diagnosis of IBD were enrolled. The demographic profile at the first visit, family history of IBD, smoking history, time from first symptom onset to diagnosis, use of anti-tuberculousis treatment before IBD-specific treatment, disease phenotype, and medication history were collected by interview and chart review. Disease and family history and treatments used were updated at each follow-up visit. RESULTS Of 4006 persons enrolled, 59.9% had ulcerative colitis (UC) and the majority were male (60.3%). The median diagnostic delay in both UC and Crohn's disease (CD) was at least 2 years. At the time of diagnosis only 4.5% of CD were smokers and only 3.8% of UC were ex-smokers. Positive family history was uncommon (2.1%). The phenotype of persons with CD included 22.9% with stricturing disease and 9.4% with fistulizing disease. The most common site of disease was ileocolonic (40.9%) and only 2.5% had perineal fistulas. Among those with UC 18.7% had proctitis and 30.3% had pancolitis. CONCLUSIONS This is the largest cohort of persons with IBD reported from Asia. Although there are several demographic differences between persons with IBD from India compared with the West, the phenotypes of the disease are not highly different.

Abstract
INTRODUCTION The relationship between the incidence of intestinal tuberculosis (TB) and Crohn's disease (CD) is interesting, especially considering the striking similarity between the two conditions. Some studies from Asian populations suggested that the incidence of intestinal TB decreases when there is an increase in CD. AIM To compare the incidence trend between intestinal TB and CD over 15 years. METHODS Medical records of patients seen in the Division of Gastroenterology over 15 years (2005-2019) were reviewed. CD was diagnosed according to the Copenhagen criteria. Intestinal TB was diagnosed in the appropriate clinical situation if any one or more of the following was present: (1) positive TB MGIT culture; (2) positive Gene Xpert for TB; (3) suggestive histologic findings, with positive tissue acid-fast bacillus (AFB) on smear or with sustained response to anti-TB therapy. The incidence time trend of patients with CD and intestinal TB diagnosis was then studied year-wise. RESULTS 632 medical case records were accessed; 60 patients were excluded due to inadequate data or not fulfilling diagnostic criteria. The 572 patients included 224 with intestinal TB (median age 37 years, IQR 22; 125 [56%] females) and 348 with CD (median age 40 years, IQR 25; 159 [46%] females [p < 0.02 as compared to TB]). Thus, more patients with CD were seen during the study period, but there was no correlation between the incidence of the two conditions (r = 0.318; p = 0.25). CONCLUSION In Indian patients in a single private-sector center, there was no inverse correlation between the incidence of intestinal TB and CD over 15 years.

Abstract
Background/Aims Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn’s disease (CD), is increasingly being reported from India and other Asian countries. This study looks into the changing trends of IBD at a tertiary care center in north India over last two decades. Methods Retrospective analysis of a prospectively maintained database of patients diagnosed with IBD between January 1991 and December 2015 was conducted. The study period was divided into five times cohorts (1991–1995, 1996–2000, 2001–2005, 2006–2010, 2011–2015). Results During the study period, 2,467 patients (UC [n = 2,137, 86.6%], CD [n = 330, 13.3%], mean age 38.5 ± 13.3 years; 55.9% males) were registered. The proportion of patients with CD increased (ratio of UC to CD declined from 15.7:1 to 4:1). The mean age at diagnosis decreased for UC (45.7 ± 12.1 years in 1991–1995 vs. 37.6 ± 13.0 years in 2011–2015; P= 0.001) and remained consistent for CD (41.3 ± 13.6 years in 1996–2000 vs. 41.3 ± 16.9 years in 2011–2015, P= 0.86). Patients with proctitis in UC and isolated ileal disease in CD increased over the study period (P= 0.001 and P= 0.007, respectively). Inflammatory CD increased (P= 0.009) whereas stricturing CD decreased (P= 0.01) across all cohorts. There was a trend towards less severe presentation of both UC and CD. The use of thiopurines (P= 0.02) and biologics increased (P= 0.001) with no significant change in trends for requirements of surgery (P= 0.9). Conclusions Increasing prevalence of CD, younger age at diagnosis, diagnosis at an earlier and milder stage, greater use of thiopurines and biologics were observed.

Abstract
Evidence is emerging that inflammatory bowel diseases (IBDs) are becoming increasingly prevalent in developing countries, altering the previously held view that these were diseases of the West. Within this is a substantial increase in the burden of this disease in India, a matter of great importance to the country itself as well as in furthering our understanding of the disease. There is comparatively less data on this, both from the epidemiological standpoint as well as on disease pathogenesis in this particular cohort and is very much a subject matter of evolving understanding and research. This article aims to look at the changing global distribution of the disease and its implications. The Indian disease phenotype, and the aetiology of disease development will also be addressed with particular focus on differing pathogenetic processes in the Indian subpopulation, with consideration of what clues may be offered by the increasing incidence of the disease in this developing nation. Available evidence will be evaluated with the objective of providing a comprehensive overview of the development of IBD in India.

Abstract
Background/Aims The national registry for inflammatory bowel disease (IBD) was designed to study epidemiology and prescribing pattern of treatment of IBD in India. Methods A multicenter, cross-sectional, prospective registry was established across four geographical zones of India. Adult patients with ulcerative colitis (UC) or Crohn’s disease (CD) were enrolled between January 2014 and December 2015. Information related to demographics; disease features; complications; and treatment history were collected and analyzed. Results A total of 3,863 patients (mean age, 36.7 ± 13.6 years; 3,232 UC [83.7%] and 631 CD [16.3%]) were enrolled. The majority of patients with UC (n = 1,870, 57.9%) were from north, CD was more common in south (n = 348, 55.5%). The UC:CD ratio was 5.1:1. There was a male predominance (male:female = 1.6:1). The commonest presentation of UC was moderately severe (n = 1,939, 60%) and E2 disease (n = 1,895, 58.6%). Patients with CD most commonly presented with ileocolonic (n = 229, 36.3%) inflammatory (n = 504, 79.9%) disease. Extraintestinal manifestations were recorded among 13% and 20% of patients in UC and CD respectively. Less than 1% patients from both cohorts developed colon cancer (n = 26, 0.7%). The commonly used drugs were 5-aminosalicylates (99%) in both UC and CD followed by azathioprine (34.4%). Biologics were used in only 1.5% of patients; more commonly for UC in north and CD in south. Conclusions The national IBD registry brings out diversities in the 4 geographical zones of India. This will help in aiding research on IBD and improving quality of patient care.

Abstract
Background/Aims Crohn’s disease (CD) and intestinal tuberculosis (ITB) remain “difficult-to-differentiate” diseases. We have previously documented peripheral blood frequency of CD4+ CD25+ FOXP3+ T-regulatory cells (Treg) as a biomarker to differentiate CD and ITB. We tried to validate these results in a larger cohort of CD and ITB patients. Methods Seventy treatment naïve patients of CD (n = 23) and ITB (n = 47) (diagnosed by standard criteria) were recruited prospectively from October 2016 to May 2017. Patients with history of antitubercular therapy in the past were excluded. The frequency of Treg cells in peripheral blood was determined by flow cytometry, and compared between CD and ITB patients. Results Similar to our previous study, frequency of Treg cells in peripheral blood was significantly increased in ITB as compared to CD patients (40.9 [interquartile range, 33–50] vs. 24.9 [interquartile range, 14.4–29.6], P<0.001). Further, the receiver operating characteristics curve also showed good diagnostic accuracy with an area under the curve (AUC) of 0.77 (95% confidence interval, 0.65–0.89) and a FOXP3+ cutoff value of > 31.3% had a sensitivity and specificity of 83% and 82.6% respectively, to differentiate ITB from CD. Even for the indeterminate cases (n = 33), Treg cell frequency had similar diagnostic accuracy with an AUC of 0.85 (95% confidence interval, 0.68–0.95) and a cutoff of 32.37% had sensitivity and specificity of 87% and 95% respectively, to differentiate ITB from CD. Conclusions The current findings validate that the increased frequency of CD4+ CD25+ FOXP3+ Treg in the peripheral blood can be used as a biomarker with high diagnostic accuracy to differentiate ITB from CD.

Abstract
Extramedullary plasmacytoma of the iris and ciliary body is extremely rare. We present a case which was misdiagnosed as granulomatous uveitis with neovascular glaucoma, and underwent a trabeculectomy with mitomycin-c along with iris biopsy. The post-operative period showed early bleb failure and catastrophic growth of the suspected mass. Histopathological examination revealed a diagnosis iris plasmacytoma. Subsequent ultrasound biomicroscopy showed involvement of the iris and ciliary body. A prompt systemic workup was done, and an associated systemic plasma cell dyscrasia was ruled out. The affected eye was enucleated, and the patient remains disease free at the end of 3-year follow-up.

Abstract
Introduction: Intestinal tuberculosis (ITB) and Crohn's disease (CD) have similar clinical presentation, but require different treatment approaches. Despite advances in various endoscopic, imaging, microbiological, and histological techniques, the differentiation of these two entities is often difficult. Newer radiological and image acquisition modalities have now become indispensable tools for evaluation of these two diseases.Areas covered: This review summarizes the currently available literature on various radiological investigations to differentiate ITB from CD. This review also enumerates the newer modalities in image acquisition techniques and their potential role for differentiating these two diseases. At present abdominal computed tomography (CT) scan is used as a first line investigation for differentiating ITB from CD. Magnetic resonance imaging (MRI) is preferred in pediatric patients and for follow-up studies.Expert opinion: Role of newer modalities like contrast enhanced abdominal ultrasound, perfusion CT, advanced MRI and positron emission tomography (PET) is evolving and requires further exploration. Till further robust studies are available, differentiation between ITB and CD requires use of a combination of clinical, endoscopic, serological, histological, and radiological parameters rather than relying on a single test.

Abstract
Background This study aimed to understand the disease characteristics and treatment outcomes of Crohn’s disease (CD) in a real-world setting in China. Methods In this prospective, non-interventional, multicenter disease registry, adults (≥18 years) with existing and newly diagnosed CD were recruited from 14 medical centers across China from January 2015 to January 2017. The study consisted of the enrollment and follow-up periods, of 12 months each. Demographic, clinical characteristics, diagnostic duration and management of CD at enrollment were evaluated. Logistic regression analysis and stepwise multivariate logistic regression analysis used to assess the relationship between the risk factors and CD. Results Of 504 enrolled patients, 499 (99.0%) were eligible for analysis. The mean (SD) age at study enrollment was 32.3 (11.43) years and the majority (69.7%) of participants were male. In the past 15 years, a sustained decrease of the period of time in the diagnosis of CD was observed, at about 39.4 (24.11) months in 2010, which decreased to 3.1 (2.13) months in 2015. The most common presenting symptoms of CD included abdominal pain (78.0%), diarrhea (58.1%), weight loss (52.9%) and fever (30.1%). Oral ulcer (19.4%) and arthritis (9.8%) were the most common extra-intestinal manifestations. Non-stricturing non-penetrating (B1) (49.9%) behavior and ileocolonic involvement (L3) (56.2%) location were more frequent. Perianal disease was observed in 29.1% of the patients. Around 23.8% (119/499) patients had CD-related surgery other than perianal disease surgery. Older age at enrollment, longer disease course, complicated disease behavior and absence of perianal disease were all surgery risk factors (p < 0.05). The most common medications was immunomodulators (e.g., azathioprine) (41.5%), anti-TNFα agents (32.9%) and aminosalicylates (20.6%). The mean (SD) Crohn’s Disease Active Index (CDAI) score was 159.1 (91.45) and almost half of the patients (49.1%, 81/165) were in remission. Conclusions This study demonstrated the CD-disease characteristics, risk factors of CD-related surgery and perianal disease, and treatment strategies in a real-world setting in China and may help in developing programs to diagnose and manage patients with CD.

Abstract
Ileocecal thickening (ICT) is a common finding on radiological imaging. It can be caused by a variety of inflammatory, infectious, or neoplastic conditions, and evaluating a patient of ICT can be a challenging task. Intestinal tuberculosis (ITB), Crohn's disease (CD), and adenocarcinoma are the most common causes. Enteric bacterial infections, cytomegalovirus, histoplasmosis, amebiasis, systemic vasculitis, lymphoma, etc. should be suspected in appropriate clinical settings. However, it could often be a spurious or nonspecific finding. A thickness of more than 3 mm in a normally distended small bowel is usually considered abnormal. Detailed evaluation of imaging of the site and extent of thickening; the degree and pattern of thickening; and the associated findings, such as degree of fat stranding, fibrofatty proliferation, adjacent lymph nodes, and solid organ involvement, should be performed. Ileocolonoscopy is an important tool for diagnosing and obtaining samples for tissue diagnosis. Histopathology is usually the gold standard for diagnosis, although—not uncommonly—findings could be nonspecific, and reaching a definitive diagnosis is difficult. As such, a systematic approach with the integration of clinical, biochemical, radiological, endoscopic, histological, and other laboratory tests is the key to reaching a diagnosis. In this article, we review the causes of ICT and present a clinical approach for the management of ICT.

Abstract
OBJECTIVES Differentiating Crohn's disease (CD) from intestinal tuberculosis (ITB) remains a diagnostic challenge. Misdiagnosis carries potential grave implications. We aimed to develop and validate a novel diagnostic nomogram for differentiating them. METHODS In total, 310 eligible patients were recruited from 6 tertiary inflammatory bowel disease centers. Among them, 212 consecutive patients (143 CD and 69 ITB) were used in the derivation cohort for the establishment of diagnostic equation and nomogram; 7 investigative modalities including clinical manifestations, laboratory results, endoscopic findings, computed tomography enterography features, and histology results were used to derive the diagnostic model and nomogram. Ninety-eight consecutive patients (76 CD and 22 ITB) were included for validation of the diagnostic model. RESULTS Eight out of total 79 parameters were identified as valuable parameters used for establishing diagnostic equations. Two regression models were built based on 7 differential variables: age, transverse ulcer, rectum involvement, skipped involvement of the small bowel, target sign, comb sign, and interferon-gamma release assays (for model 1) or purified protein derivative (for model 2), respectively. Accordingly, 2 nomograms of the above 2 models were developed for clinical practical use, respectively. Further validation test verified the efficacy of the nomogram 1 with 90.9% specificity, 86.8% sensitivity, 97.1% PPV, 66.7% negative predictive value (NPV), and 87.8% accuracy for identifying CD, and the efficacy of the nomogram 2 with 100% specificity, 84.2% sensitivity, 100% positive predictive value, 64.7% NPV, and 87.8% accuracy for diagnosing CD. CONCLUSIONS The derivation and validation cohorts identified and validated 2 highly accurate and practical diagnostic nomograms for differentiating CD from ITB. These diagnostic nomograms can be conveniently used to identify some difficult CD or ITB cases, allowing for decision-making in a clinical setting.

Abstract
BACKGROUND The literature on disease characteristics of colonic Crohn's disease (CD) is sparse, especially from Asia, where the burden of inflammatory bowel disease is on the rise. The present study aims to describe the disease characteristics of colonic CD, and compare it with that of ileal/ileocolonic disease. METHODS This retrospective study included adult patients of CD (diagnosed by standard criteria, follow-up duration > 6 months) on follow-up between August 2004 and January 2016. The disease location was classified by Montreal classification. The data were recorded on demographic characteristics, smoking status, disease phenotype, disease course, treatment received, hospitalization and surgeries. RESULTS Of 406 CD patients, 123 had colonic [mean age (at onset) 30.4 ± 13.2 years, 59.3% males] and 265 had ileal/ileocolonic disease [mean age (at onset) 32.9 ± 13.8 years, 61.5% males] while 18 patients had isolated upper GI disease. The frequency of inflammatory behavior (B1 phenotype; 61.8 vs. 46.4%, p = 0.003), perianal disease (23.6 vs. 4.5%, p < 0.001), and extra-intestinal manifestation (42.3 vs. 30.2%, p = 0.019) was higher in colonic than ileal/ileocolonic CD. Though not statistically significant, requirement of atleast one course of steroid was lower in colonic CD (72.7 vs. 84.2%, p = 0.098). Although there was no difference in the frequency of hospitalization (30.1 vs. 27.1%, p = 0.45), the overall requirement for surgery was significantly lower in colonic CD (17.1 vs. 26.1%, p = 0.032) and patients with colonic disease had a lower cumulative probability of first surgery in the first 10 years of follow-up [Hazard ratio 0.556 (95% CI 0.313-0.985), p = 0.045]. CONCLUSION Colonic CD was associated with less aggressive disease behavior and lower requirement of surgery as compared to ileal/ileocolonic CD.

Combination of increased visceral fat and long segment involvement: Development and validation of an updated imaging marker for differentiating Crohn's disease from intestinal tuberculosis. J Gastroenterol Hepatol 2018; 33:1234-1241. [PMID: 29205485 DOI: 10.1111/jgh.14065] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2017] [Revised: 11/26/2017] [Accepted: 11/27/2017] [Indexed: 12/14/2022]
Abstract
BACKGROUND AND AIM Computed tomographic (CT) features (long segment, ileocaecal area involvement, and lymph nodes > 1 cm) have demonstrated good specificity but poor sensitivity, while visceral to subcutaneous fat ratio on CT (VF/SC > 0.63) has moderate sensitivity and specificity in differentiating Crohn's disease (CD) and intestinal tuberculosis (ITB). This study aims to develop and validate an updated model incorporating CT features and VF/SC to improve the diagnostic accuracy of imaging in differentiating CD/ITB. METHODS Computed tomographic features and VF/SC were documented in two cohorts (development [n = 59, follow-up: January 2012 to November 2014] and validation [n = 69, follow-up: December 2014 to December 2015]) of CD/ITB patients diagnosed by standard criteria. Patients with normal CT were excluded. Features significantly different between CD/ITB were incorporated into a model. RESULTS In both the cohorts, necrotic lymph nodes were exclusive for ITB (23.1% vs 0% and 43.3% vs 0%), while long segment involvement (57.6% vs 7.7%, P < 0.001, and 52.6% vs 16.1%, P < 0.001) and VF/SC ratio > 0.63 (72.7% vs 19.2%, P < 0.001, and 81.6% vs 25.8%, P < 0.001) were significantly more common in CD. A risk score of 2, based upon long segment involvement and VF/SC ratio > 0.63, had an excellent specificity of 100% and 100% and sensitivity of 54% and 50% for CD in development and validation cohorts, respectively. Based upon these features, in 43% patients with the diagnostic dilemma of CD/ITB, a definite diagnosis based only on imaging could be made. CONCLUSION Necrotic lymph nodes are exclusive for ITB, and the combination of long segment involvement and VF/SC ratio > 0.63 is exclusive for CD, and these features can make a definite diagnosis in 43% patients with a CD/ITB dilemma.

Abstract
BACKGROUND The diagnosis of Crohn's disease (CD) can be delayed in clinical practice. In tuberculosis endemic areas, empirical anti-tubercular therapy further delays treatment. AIM(S) To assess risk factors for diagnostic delay and its impact on the long-term complications of Crohn's disease in India where tuberculosis is endemic. METHODS Data from a large prospectively established inflammatory bowel disease registry were analysed retrospectively. The time from onset of symptoms to diagnosis (diagnostic delay) was calculated and categorised into two groups based on median diagnostic delay. The risk factors for delay including anti-tubercular therapy were analysed. Logistic regression analysis was done to assess impact of diagnostic delay on development of stenotic and fistular complications including need for surgery. RESULTS Seven hundred and twenty Crohn's disease patients (60.3% male, median: 28 years) were included. Main outcome measures were stenosis, fistula and need for surgery. Subjects with diagnostic delay >18 months (median) developed significantly higher stenotic complications and surgery (OR 4.12; 95% CI: 2.74-6.33, P < 0.001 and OR 2.41, 95% CI: 1.68-3.42, P < 0.001), respectively, compared to those ≤18 months. There was no difference in the development of fistulous complications. 193/720 (27%) received anti-tubercular therapy which significantly contributed to diagnostic delay (OR: 2.47; 95% CI: 1.76-3.47, P < 0.001) with 47% showing initial clinical response (Crohn's disease activity index- CDAI decrease >100). Moreover, the incidence of stenotic complications was significantly higher in patients who had received prior anti-tubercular therapy (55/193 (28.49%) vs 78/527 (14.8%), P < 0.001, OR: 2.60, 95% CI: 1.64-4.12). CONCLUSIONS Diagnostic delay in Crohn's disease is associated with significantly higher stenotic complications and need for surgery. Empirical anti-tubercular therapy is the single largest contributor to diagnostic delay in tuberculosis endemic areas. Despite initial clinical response to anti-tubercular therapy, long-term stenotic complications are higher.

Abstract
INTRODUCTION Environmental risk factors have been associated with inflammatory bowel disease (IBD). With rising incidence, it is important to know risk factors associated with IBD in our population. This study was aimed to evaluate risk factors for IBD from western India. METHODS This was prospective, multi-center case-control study which included 1054 patients with IBD of which 765 (72.5%) were ulcerative colitis (UC) and 289 (27.4%) Crohn's disease (CD). Asymptomatic individuals without a history of any major illness served as controls. The questionnaire containing risk factors for IBD was given to patients and control group. Odds ratio and 95% confidence interval were calculated for each variable. RESULT Significant numbers of patients with CD were from rural area. Rural environment (OR 1.071, 0.82-1.38 and OR 1.441, 1.02-2.02), higher education (OR 1.830, 1.52-2.19 and OR 1.519, 1.16-1.97), professional by occupation (OR 1.754, 1.46-2.09 and OR 1.293, 0.99-1.67), annual family income >100,000 Indian national rupees (OR 2.185, 1.52-3.13 and OR 4.648, 3.10-6.95), history of appendectomy (OR 3.158, 1.71-5.80 and OR 3.158, 1.71-5.80), and family history of IBD (OR 4.510, 2.19-9.25 and OR 3.972, 1.58-9.96) were the risk factors for UC and CD, respectively. Vegetarian diet was protective factor for UC (OR 0.29, 0.27-0.39) and risk for CD (OR 1.179, 0.88-1.57). Smoking and chronic alcoholism were not found to be the risk factors. CONCLUSION This study highlights association between socioeconomic, dietary factors, appendectomy, and family history as risk factors for IBD.

Abstract
BACKGROUND Distinguishing between Crohn's Disease (CD) and Intestinal Tuberculosis (ITB) has been a challenging task for clinicians due to their similar presentation. CD4+FOXP3+ T regulatory cells (Tregs) have been reported to be increased in patients with pulmonary tuberculosis. However, there is no such data available in ITB. The aim of this study was to investigate the differential expression of FOXP3+ T cells in patients with ITB and CD and its utility as a biomarker. METHODS The study prospectively recruited 124 patients with CD, ITB and controls: ulcerative colitis (UC) and patients with only haemorrhoidal bleed. Frequency of CD4+CD25+FOXP3+ Tregs in peripheral blood (flow cytometry), FOXP3 mRNA expression in blood and colonic mucosa (qPCR) and FOXP3+ T cells in colonic mucosa (immunohistochemistry) were compared between controls, CD and ITB patients. RESULTS Frequency of CD4+CD25+FOXP3+ Treg cells in peripheral blood was significantly increased in ITB as compared to CD. Similarly, significant increase in FOXP3+ T cells and FOXP3 mRNA expression was observed in colonic mucosa of ITB as compared to CD. ROC curve showed that a value of >32.5% for FOXP3+ cells in peripheral blood could differentiate between CD and ITB with a sensitivity of 75% and a specificity of 90.6%. CONCLUSION Phenotypic enumeration of peripheral CD4+CD25+FOXP3+ Treg cells can be used as a non-invasive biomarker in clinics with a high diagnostic accuracy to differentiate between ITB and CD in regions where TB is endemic.

Abstract
OBJECTIVES The aim of the study was to evaluate clinical, endoscopic, radiologic, and histopathological features helpful in differentiating Crohn disease (CD) from intestinal tuberculosis (ITB) in children. METHODS Patients diagnosed to have CD or ITB based on standard recommended criteria were enrolled. Children with inflammatory bowel disease unclassified or suspected ITB or CD with incomplete work-up or lost to follow-up were excluded. The clinical and laboratory (radiology, endoscopy, and histology) details of children were analyzed. RESULTS Twenty cases of ITB (14 [3-17] years) and 23 of CD (11 [1-17] years) were enrolled. Presentation with chronic diarrhea (82% vs 40%; P = 0.006) and blood in stool (74% vs 10%; P = 0.001) favored CD, whereas subacute intestinal obstruction (20% vs 0%; P = 0.04) and ascites (30% vs 0%; P = 0.005) favored ITB. Presence of deep ulcers (61% vs 30%; P = 0.04), longitudinal ulcers (48% vs 15%; P = 0.02), involvement of multiple colonic segments (70% vs 35%; P = 0.02), left-sided colon (87% vs 40%; P = 0.003), extraintestinal manifestations (21.7% vs 0%; P = 0.02), and higher platelet count (3.9 vs 2.6 × 10/mm; P = 0.02) favored CD. Isolated ileocecal involvement (40% vs 8.7%; P = 0.03) was a feature of ITB. TB bacilli were demonstrated in 40% ITB cases (colon-6, ascites-1, abdominal lymph node-1). On multivariate analysis, presence of blood in stool (odds ratio: 37.5 [confidence interval: 3.85-365.72], P = 0.002) and left-sided colonic involvement (odds ratio: 16.2 [confidence interval: 1.63-161.98], P = 0.02) were independent predictors of CD. CONCLUSIONS Microbiologic confirmation of tuberculosis is possible in 40% ITB cases. Presence of blood in stool and left-sided colonic involvement are the most important features favoring CD.

Abstract
BACKGROUND Inflammatory bowel disease (IBD), once considered to be a Western disease, is increasingly being reported from India and other Asian countries. The present review summarizes epidemiology and disease characteristics of IBD in India with reference to other Asian countries and the West. SUMMARY India is projected to have one of the highest disease burden of IBD across the globe. The overall genetic risk and microbial signature in Indian IBD patients are similar to those of patients in the West as demonstrated by the similar incidence of IBD in second-generation Indian immigrants and matching perturbations in the structural and functional component of gut microbiota in Indian studies. The concept of the hygiene hypothesis continues to remain controversial with Indian studies demonstrating contradictory findings. The disease characteristics, long-term outcomes including the risk of colorectal cancer, and the effect of pregnancy on IBD and vice versa in Indian patients with IBD are in general similar with few differences. Unlike patients in the West, very few Indian patients have a positive family history. KEY MESSAGE The Indian disease pattern is going through a phase of epidemiological transition with a surge in the incidence of IBD. The epidemiology and disease characteristics of IBD mirror the patterns observed in the West.

Abstract
Abdominal computed tomography (CT) can noninvasively image the entire gastrointestinal tract and assess extraintestinal features that are important in differentiating Crohn's disease (CD) and intestinal tuberculosis (ITB). The present meta-analysis pooled the results of all studies on the role of CT abdomen in differentiating between CD and ITB. We searched PubMed and Embase for all publications in English that analyzed the features differentiating between CD and ITB on abdominal CT. The features included comb sign, necrotic lymph nodes, asymmetric bowel wall thickening, skip lesions, fibrofatty proliferation, mural stratification, ileocaecal area, long segment, and left colonic involvements. Sensitivity, specificity, positive and negative likelihood ratios, and diagnostic odds ratio (DOR) were calculated for all the features. Symmetric receiver operating characteristic curve was plotted for features present in >3 studies. Heterogeneity and publication bias was assessed and sensitivity analysis was performed by excluding studies that compared features on conventional abdominal CT instead of CT enterography (CTE). We included 6 studies (4 CTE, 1 conventional abdominal CT, and 1 CTE+conventional abdominal CT) involving 417 and 195 patients with CD and ITB, respectively. Necrotic lymph nodes had the highest diagnostic accuracy (sensitivity, 23%; specificity, 100%; DOR, 30.2) for ITB diagnosis, and comb sign (sensitivity, 82%; specificity, 81%; DOR, 21.5) followed by skip lesions (sensitivity, 86%; specificity, 74%; DOR, 16.5) had the highest diagnostic accuracy for CD diagnosis. On sensitivity analysis, the diagnostic accuracy of other features excluding asymmetric bowel wall thickening remained similar. Necrotic lymph nodes and comb sign on abdominal CT had the best diagnostic accuracy in differentiating CD and ITB.

Abstract
BACKGROUND AND AIM Crohn's disease (CD) and intestinal tuberculosis (ITB) have close phenotypic resemblance. Mesenteric fat (a component of visceral fat [VF]) hypertrophy and fat wrapping, which is visible radiologically as fibrofatty proliferation, is seen more commonly in CD than in ITB. AIM The present study was conducted to study the role of VF in differentiating CD and ITB. METHODS Visceral fat area and subcutaneous (SC) fat area were measured on computed tomography in two cohorts (development and validation). VF/SC ratio was also calculated for all patients. In the development cohort, retrospective data collection was carried out for 75 patients with CD and ITB who were on follow-up from January 2012 to November 2014. In the validation cohort, 82 patients were recruited prospectively from December 2014 to December 2015 and were diagnosed as CD or ITB according to standard diagnostic criteria. RESULTS Visceral fat area and VF/SC ratio were significantly higher in CD patients (n = 42: development, n = 46: validation) than in ITB patients (n = 33: development, n = 36: validation) in both the development (106.2 ± 63.5 vs 37.3 ± 22, P = <0.001; 1.1 ± 0.57 vs 0.43 ± 0.24, P = <0.001) and validation cohorts (102.2 ± 69.8 vs 55.8 ± 44.9, P = 0.01; 1.2 ± 0.68 vs 0.56 ± 0.33, P = <0.001). A cut-off of 0.63 for VF/SC ratio in the development cohort had a high sensitivity (82%) and specificity (81%) in differentiating CD and ITB. Similar sensitivity (81%) and specificity (78%) were seen when this cut-off was applied in the validation cohort. CONCLUSION The VF/SC ratio is a simple, cost-effective, non-invasive and single objective parameter with a good sensitivity and specificity to differentiate CD and ITB.

Abstract
BACKGROUND Differentiation between intestinal tuberculosis and Crohn's disease is difficult and may require therapeutic trial with anti-tubercular therapy in tuberculosis-endemic regions. AIM To evaluate the role of therapeutic trial with anti-tubercular therapy in patients with diagnostic confusion between intestinal tuberculosis and Crohn's disease. METHODS We performed retrospective-comparative (n = 288: 131 patients who received anti-tubercular therapy before being diagnosed as Crohn's disease and 157 intestinal tuberculosis patients) and prospective-validation study (n = 55 patients with diagnostic confusion of intestinal tuberculosis/Crohn's disease). Outcomes assessed were global symptomatic response and endoscopic mucosal healing. RESULTS In the derivation cohort, among those eventually diagnosed as Crohn's disease, global symptomatic response with anti-tubercular therapy was seen in 38% at 3 months and in 37% who completed 6 months of anti-tubercular therapy. Ninety-four per cent of intestinal tuberculosis patients showed global symptomatic response by 3 months. Endoscopic mucosal healing was seen in only 5% of patients with Crohn's disease compared with 100% of intestinal tuberculosis patients. In the validation cohort, all the patients with intestinal tuberculosis had symptomatic response and endoscopic mucosal healing after 6 months of anti-tubercular therapy. Among the patients with an eventual diagnosis of Crohn's disease, symptomatic response was seen in 64% at 2 months and in 31% who completed 6 months of anti-tubercular therapy, none had mucosal healing. CONCLUSIONS Disproportionately lower mucosal healing rate despite an overall symptom response with 6 months of anti-tubercular therapy in patients with Crohn's disease suggests a need for repeat colonoscopy for diagnosing Crohn's disease. Patients with intestinal tuberculosis showing significant symptomatic response after 2-3 months of anti-tubercular therapy, suggest that symptom persistence after a therapeutic trial of 3 months of anti-tubercular therapy may indicate the diagnosis of Crohn's disease.

Abstract
INTRODUCTION Anti-TNF agents are the mainstay of therapy in patients with moderate to severe ulcerative colitis (UC) not responding to 5-aminosalisylic acid, corticosteroids, immunmodulators and for patients dependent on corticosteroids. There is a therapeutic gap of 30%- 60% with infliximab and adalimumab, which is required to be bridged by newer agents. The present review summarizes the literature on the role of golimumab, a new anti TNF agent, in ulcerative colitis. AREAS COVERED Literature search was done on PubMed using the search terms 'golimumab' AND 'ulcerative colitis' from inception till March 2016. Golimumab, a fully human monoclonal antibody against TNF-α, was approved by FDA for clinical use in UC in 2013. In vitro studies showed golimumab to be better than infliximab and adalimumab in terms of affinity and neutralization of TNF-α and its conformational stability. Golimumab was found to be effective and safe in inducing and maintaining clinical remission, clinical response and mucosal healing in patients with UC in the two registration trials. Expert commentary: Although there is no difference in terms of efficacy between golimumab, infliximab and adalimumab, golimumab is better than infliximab in terms of route of administration (subcutaneous vs intravenous) and better than adalimumab in terms of frequency of dosing (4 weeks vs 2 weeks).

Abstract
Intestinal tuberculosis is a common clinical problem in India. The clinical features of this disease are nonspecific and can be very similar to Crohn's disease. Radiological evaluation of the small bowel has undergone a paradigm shift in the last decade. This long tubular organ that has traditionally been difficult to evaluate can now be well-visualized by some innovative imaging and endoscopic techniques. This article highlights the state-of-the-art evaluation of ulceroconstrictive diseases of the bowel and provides recommendations for the differentiation of intestinal tuberculosis from Crohn's disease.

Temporal Change in Phenotypic Behaviour in Patients with Crohn's Disease: Do Indian Patients Behave Differently from Western and Other Asian Patients? J Crohns Colitis 2016; 10:255-61. [PMID: 26519461 PMCID: PMC4957468 DOI: 10.1093/ecco-jcc/jjv202] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/27/2015] [Accepted: 10/25/2015] [Indexed: 12/11/2022]
Abstract
BACKGROUND AND AIMS In Western studies, one-third of patients with Crohn's disease have stricturing or penetrating disease at presentation and one-half will progress to complicated disease in 20 years. Asian studies indicate that the Asian disease phenotype may be different. Our aim was to study the disease behaviour in Indian patients with Crohn's disease. METHODS In this hospital-based study, we analysed [Montreal classification] disease phenotype, presence of perianal disease, need for intestinal surgery, and changes in the Montreal classification over time in Crohn's disease patients from our database. RESULTS In the 178 patients (median age 35, interquartile range [IQR] 21 years; 97 males) with Crohn's disease, the proportion of various features was as follows. More patients had ileo-colonic[L3: 43.8%] than ileal[L1: 27.5%] or colonic[L2: 28.7%] disease. Perianal disease was seen in 11.8% at baseline. Non-stricturing, non-fistulising disease[B1] was seen in 74.7%, 65.7%, 50%, and 44.4% at baseline, at 5, 10 and 15 years, respectively. Stricturing disease[B2] was seen in 21.4%, 21.9%, 28.9%, and 33.3%; penetrating disease[B3] in 3.9%, 11.4%, 21%, and 16.7%; and intestinal surgery was required in 10.7%, 20%, 34.2%, and 55.5%, respectively. KaplanMeier analysis showed no association between progression of disease and patient age or the location of the disease. CONCLUSIONS Gender distribution and predominant ileo-colonic location of disease were similar to earlier Asian reports on Crohn's disease. Perianal disease was less frequent than reported in Western and other Asian studies. One-fourth of Indian patients had aggressive disease at diagnosis, but the tendency to progress towards aggressive disease over time was less pronounced than in Western patients.
