Abstract
The misdiagnosis of intestinal tuberculosis (ITB), such as Crohn's disease (CD), and subsequent treatment with immunosuppressive therapies can lead to severe outcomes. However, the differential diagnosis between these two conditions can be challenging. We herein report a patient from Myanmar who was initially diagnosed with CD due to the presence of non-caseating granulomas. The patient's symptoms were aggravated with steroid treatment, eventually leading to a diagnosis of ITB. In the international medical community, we encounter patients from countries, such as Myanmar, where tuberculosis is endemic. Therefore, it is necessary to understand the epidemiological background of each country to accurately distinguish between CD and ITB.

Abstract
This study aimed to develop and evaluate a CT-based deep learning radiomics model for differentiating between Crohn's disease (CD) and intestinal tuberculosis (ITB). A total of 330 patients with pathologically confirmed as CD or ITB from the First Affiliated Hospital of Zhengzhou University were divided into the validation dataset one (CD: 167; ITB: 57) and validation dataset two (CD: 78; ITB: 28). Based on the validation dataset one, the synthetic minority oversampling technique (SMOTE) was adopted to create balanced dataset as training data for feature selection and model construction. The handcrafted and deep learning (DL) radiomics features were extracted from the arterial and venous phases images, respectively. The interobserver consistency analysis, Spearman's correlation, univariate analysis, and the least absolute shrinkage and selection operator (LASSO) regression were used to select features. Based on extracted multi-phase radiomics features, six logistic regression models were finally constructed. The diagnostic performances of different models were compared using ROC analysis and Delong test. The arterial-venous combined deep learning radiomics model for differentiating between CD and ITB showed a high prediction quality with AUCs of 0.885, 0.877, and 0.800 in SMOTE dataset, validation dataset one, and validation dataset two, respectively. Moreover, the deep learning radiomics model outperformed the handcrafted radiomics model in same phase images. In validation dataset one, the Delong test results indicated that there was a significant difference in the AUC of the arterial models (p = 0.037), while not in venous and arterial-venous combined models (p = 0.398 and p = 0.265) as comparing deep learning radiomics models and handcrafted radiomics models. In our study, the arterial-venous combined model based on deep learning radiomics analysis exhibited good performance in differentiating between CD and ITB.

Abstract
INTRODUCTION The diagnosis of intestinal tuberculosis is challenging even nowadays. This study aims to report the positivity rates of new diagnostic methods such as immunohistochemistry and Real-Time Polymerase Chain Reaction in patients with intestinal tuberculosis, as well as describe the pathological and endoscopic features of intestinal tuberculosis in our population. METHODS This was a retrospective observational study conducted in patients diagnosed with intestinal tuberculosis, between 2010 to 2023 from the Hospital Nacional Daniel Alcides Carrion and a Private Pathology Center, both located in Peru. Clinical data was obtained, histologic features were independently re-evaluated by three pathologists; and immunohistochemistry and real-time Polymerase Chain Reaction evaluation were performed. The 33 patients with intestinal tuberculosis who fulfilled the inclusion criteria were recruited. RESULTS Immunohistochemistry was positive in 90.9% of cases, while real-time Polymerase Chain Reaction was positive in 38.7%. The ileocecal region was the most affected area (33.3%), and the most frequent endoscopic appearance was an ulcer (63.6%). Most of the granulomas were composed solely of epithelioid histiocytes (75.8%). Crypt architectural disarray was the second most frequent histologic finding (78.8%) after granulomas, but most of them were mild. CONCLUSION Since immunohistochemistry does not require an intact cell wall, it demonstrates higher sensitivity compared to Ziehl-Neelsen staining. Therefore, it could be helpful for the diagnosis of paucibacillary tuberculosis.

Abstract
Gastrointestinal Tuberculosis (GITB) and Crohn's disease (CD) are both chronic granulomatous diseases with a predilection to involve primarily the terminal ileum. GITB is often considered a disease of the developing world, while CD and inflammatory bowel disease are considered a disease of the developed world. But in recent times, the epidemiology of both diseases has changed. Differentiating GITB from CD is of immense clinical importance as the management of both diseases differs. While GITB needs anti-tubercular therapy (ATT), CD needs immunosuppressive therapy. Misdiagnosis or a delay in diagnosis can lead to catastrophic consequences. Most of the clinical features, endoscopic findings, and imaging features are not pathognomonic for either of these two conditions. The definitive diagnosis of GITB can be clinched only in a fraction of cases with microbiological positivity (acid-fast bacilli, mycobacterial culture, or PCR-based tests). In most cases, the diagnosis is often based on consistent clinical, endoscopic, imaging, and histological findings. Similarly, no single finding can conclusively diagnose CD. Multiparametric-based predictive models incorporating clinical, endoscopy findings, histology, radiology, and serology have been used to differentiate GITB from CD with varied results. However, it is limited by the lack of validation studies for most such models. Many patients, especially in TB endemic regions, are initiated on a trial of ATT to see for an objective response to therapy. Early mucosal response assessed at two months is an objective marker of response to ATT. Prolonged ATT in CD is recognized to have a fibrotic effect. Therefore, early discrimination may be vital in preventing the delay in the diagnosis of CD and avoiding a complicated course.

Abstract
Distinguishing inflammatory bowel disease (IBD) from its mimics remains a diagnostic challenge for surgical pathologists. Several gastrointestinal infections produce inflammatory patterns that overlap with typical findings of IBD. Although stool culture, PCR, and other clinical assays may identify infectious enterocolitides, these tests may not be performed or the results may be unavailable at the time of histologic evaluation. Furthermore, some clinical tests, including stool PCR, may reflect past exposure rather than ongoing infection. It is important for surgical pathologists to be knowledgeable about infections that simulate IBD in order to generate an accurate differential diagnosis, perform appropriate ancillary studies, and prompt clinical follow-up. This review covers bacterial, fungal, and protozoal infections in the differential diagnosis of IBD.

Abstract
BACKGROUND To establish the epidemiology and patterns of care of Crohn's Disease in low- and lower-middle-income countries. METHODS A cross-sectional survey of gastroenterology providers in countries where the world's poorest billion live was conducted to learn more about the state of diagnostic and treatment capacity for Crohn's. Quantitative data were analyzed in R and Excel. RESULTS A total of 46 survey responses from 15 countries were received, giving a response rate of 54.8%. All responses collected were from providers practicing in Africa and South Asia. The mean number of patients with Crohn's cared for in the last year was 89.5 overall but ranged from 0 reported at one facility in Rwanda to 1000 reported at two different facilities in India. Overall, Crohn's disease made up 20.6% of the inflammatory bowel disease diagnoses reported by survey respondents, with Africa exhibiting a larger proportion of Crohn's compared to ulcerative colitis than Asia. Most providers reported that patients with Crohn's have symptoms for 6-24 months prior to diagnosis and that 26-50% of their patients live in rural areas. The most reported diagnostic challenges are differentiating between Crohn's and intestinal tuberculosis, poor disease awareness, and lack of trained pathologists. The most widely reported challenge in managing Crohn's disease is patients' inability to afford biologics, reported by 65% of providers. CONCLUSION Our study suggests there may be a greater burden of Crohn's disease in low- and lower-middle-income countries than is indicated in prior literature. Respondents reported many challenges in diagnosing and treating Crohn's disease.

Abstract
Gastrointestinal tuberculosis (GITB) and Crohn’s disease (CD) are close mimics. This prospective study aimed to evaluate the diagnostic performance of perfusion computed tomography (CT) in differentiating GITB from CD. Consecutive patients with ileocaecal thickening underwent perfusion CT of the ileocaecal region between January 2019 and July 2020. Two radiologists (blinded to the final diagnosis) independently assessed blood flow (BF), blood volume (BV), mean transit time (MTT), and permeability at perfusion CT. These parameters were compared among the patients with GITB as well as active and inactive CD. Receiver operating characteristic curves were utilized for determining the diagnostic performance of perfusion CT. Interclass correlation coefficient and Bland–Altman analysis were performed to compare the observations of the two radiologists. During the study period, 34 patients underwent perfusion CT. Eight patients had diagnoses other than intestinal tuberculosis or CD. Thus, 26 patients (mean age 36 ± 14 years, 18 males) with GITB (n = 11), active CD (n = 6), and inactive CD (n = 9) were evaluated. BF, MTT, and permeability showed significant differences among the groups, while BV did not differ significantly among the groups. BF and permeability had 100% sensitivity and 100% specificity, while MTT had 61.5–100% sensitivity and 70–100% specificity for differentiating GITB from active CD and active from inactive CD. The interclass correlation coefficient for perfusion CT parameters was 0.88–1. Perfusion CT is a novel imaging technique that can improve the diagnostic performance of differentiating tuberculosis from CD.

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 Isolated ileo-cecal region (ICR) ulcers may represent underlying Crohn's disease (CD), intestinal tuberculosis (ITB), bacterial infections (including typhoid), amoebiasis, eosinophilic enteritis, drug-induced sequelae, or neoplasm. Overlapping morphological and microscopic characteristics of many of these diseases make it challenging to unequivocally confirm a diagnosis. Aims The aim of the study was to investigate the etiology and clinical outcomes of isolated ileo-cecal ulcers discovered during an ileocolonoscopy in patients with gastrointestinal symptoms. Methods Patients with isolated ileo-cecal ulcers and symptoms within the age range of 10 - 80 years were included in the study (N = 100). Patients not giving consent (assent in case of a minor), with a prior diagnosis of tuberculosis or inflammatory bowel disease, with incomplete colonoscopy and associated colonic lesions other than ICR were excluded from the study. Demographics, clinical information, and relevant biochemical and serological tests were recorded. During the colonoscopy, multiple biopsies were taken from the ileo-cecal ulcers for histopathological examination. Repeat ileocolonoscopy was performed as needed in consenting patients. Results The mean age and mean duration of symptoms were 36.0 ± 15.6 years and 18.8 ± 21.6 months, respectively. The majority of the patients presented with abdominal pain (59%), followed by diarrhea (47%), weight loss (20%), gastrointestinal bleeding (15%), and fever (11%). A history of taking nonsteroidal anti-inflammatory drugs was present in only 5% of the patients. Mean hemoglobin, C-reactive protein, and albumin levels were 11.6 ± 2.8 g/dL, 6.9 ± 9.5 mg/L, and 3.7 ± 0.8 g/dL, respectively. Based on clinical, colonoscopic, and histopathological findings, initial treatment was symptomatic/antibiotics in 55%, anti-tubercular treatment in 21%, 5-aminosalicylic acid/steroids for CD in 13%, oral budesonide in 10% of patients, and one patient was referred for management of malignancy. Final diagnoses after 8 - 24 weeks of follow-up were non-specific ileitis/colitis (45%), CD (20%), ITB (18%), infective (7%), eosinophilic ileitis/colitis (6%), non-steroidal anti-inflammatory drug-induced (2%), and amoebic and malignant in 1% of patients each. Conclusions The majority of patients with ileo-cecal ulcers have specific etiologies. Non-specific ulcers at the ICR can be managed symptomatically; however, close follow-up is necessary as sometimes the ulcers may harbor an underlying specific disease. Relevance for Patients Isolated ileo-cecal ulcers are common findings during colonoscopy in both symptomatic and asymptomatic patients. The majority of these ulcers harbor underlying significant diseases that can cause morbidity and mortality if left undiagnosed and untreated. Reaching a specific diagnosis in such cases is not straightforward, and patients are often subjected to repeat examinations.

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.

Abstract
INTRODUCTION Many diseases can imitate inflammatory bowel disease [IBD] clinically and pathologically. This review outlines the differential diagnosis of IBD and discusses morphological pointers and ancillary techniques that assist with the distinction between IBD and its mimics. METHODS European Crohn's and Colitis Organisation [ECCO] Topical Reviews are the result of an expert consensus. For this review, ECCO announced an open call to its members and formed three working groups [WGs] to study clinical aspects, pathological considerations, and the value of ancillary techniques. All WGs performed a systematic literature search. RESULTS Each WG produced a draft text and drew up provisional Current Practice Position [CPP] statements that highlighted the most important conclusions. Discussions and a preliminary voting round took place, with subsequent revision of CPP statements and text and a further meeting to agree on final statements. CONCLUSIONS Clinicians and pathologists encounter a wide variety of mimics of IBD, including infection, drug-induced disease, vascular disorders, diverticular disease, diversion proctocolitis, radiation damage, and immune disorders. Reliable distinction requires a multidisciplinary approach.

Abstract
Gastrointestinal (GI) tuberculosis (TB) remains a significant problem worldwide, and may involve the luminal GI tract from oral cavity to perianal area in addition to associated viscera and peritoneum. Although GI TB more commonly affects immunocompromised hosts, it can also occur in immunocompetent people. Diagnosis is difficult because it usually mimics a malignancy or inflammatory bowel disease. A high index of clinical suspicion and appropriate use of combined investigative methods help in early diagnosis, and reduce morbidity and mortality. Anti-TB therapy is the same as for pulmonary disease, and invasive and specialized interventions are reserved for selected complications.

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
Video capsule endoscopy has an essential role in the diagnosis and management of small bowel bleeding and is the first-line study recommended for this purpose. This article reviews the risk factors for small bowel bleeding, optimal timing for video capsule endoscopy testing, and algorithms recommended for evaluation. Used primarily for the assessment of nonacute gastrointestinal blood loss, video capsule endoscopy has an emerging role for more urgent use in emergency settings and in special populations. Future software incorporation of neural networks to enhance lesion detection will likely result in an augmented role of video capsule endoscopy in small bowel bleeding.

Abstract
BACKGROUND Response to antitubercular therapy (ATT) is often used to differentiate intestinal tuberculosis (ITB) from Crohn's disease. Role of non-invasive biomarkers to predict mucosal response to ATT is unclear. MATERIALS AND METHODS A prospective study to compare faecal calprotectin and serum C-reactive protein (CRP) levels at diagnosis, 2 and 6 months of ATT in patients with suspected ITB started on ATT was done. The patients were eventually divided into two groups: ITB or alternative diagnosis (OTH). Decline of calprotectin and CRP levels was used to compute area under the receiver operating characteristic (AUROC) to predict mucosal healing at 2 months. RESULTS Thirty-seven patients (mean age: 34.95 ± 16.35 years, 23 males) were included and 28 (75.67%) were diagnosed as ITB while nine (24.32%) had alternative diagnosis (OTH). The median faecal calprotectin values of ITB and OTH groups at baseline, 2 months and 6 months were 216 and 282 µg/g (P = 0.466), 43 and 216 µg/g (P = 0.003), and 26 and 213 µg/g (P < 0.001), respectively. The median CRP values at baseline, 2 months and 6 months were 18 and 30 mg/L (P = 0.767), 4.7 and 15 mg/L (P = 0.025), and 3 and 10.85 mg/L (P = 0.068), respectively. The AUROC of percent decline in faecal calprotectin and serum CRP at 2 months for mucosal healing were 0.8287 [95% confidence inteval (CI) 0.6472-1] and 0.6018 (95% CI 0.4079-0.7957), respectively. CONCLUSION Faecal calprotectin can help in assessing response to therapy in suspected ITB patients started on empirical ATT.

Abstract
A granuloma is defined as a localized inflammatory reaction or a hypersensitive response to a nondegradable product leading to an organized collection of epithelioid histiocytes. Etiologies of granulomatous disorders can be divided into two broad categories: infectious and noninfectious (autoimmune conditions, toxins, etc.) causes. The endless list of causalities may prove challenging for gastroenterologists and pathologists to formulate a list of clearly defined differentials. This is true when distinguishing these etiologies based on various clinical presentations and endoscopic and histological findings. We aim to provide a comprehensive review of some of the frequent and rare infectious granulomatous diseases of the gastrointestinal tract documented in the literature to date. We provide an overview of each infectious pathology with an emphasis on epidemiology, clinical presentation, and endoscopic and histologic findings, in addition to treatment.

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 Typhoid fever incidence and complications, including intestinal perforation, have declined significantly in high-income countries, with mortality rates <1%. However, an estimated 10.9 million cases still occur annually, most in low- and middle-income countries. With the availability of a new typhoid conjugate vaccine licensed for children and recommended by the World Health Organization, understanding severe complications, including associated mortality rates, is essential to inform country-level decisions on introduction of this vaccine. This scoping review summarizes over 20 years of the literature on typhoid intestinal perforation in sub-Saharan Africa. METHODS We searched EMBASE, PubMed, Medline, and Cochrane databases for studies reporting mortality rates due to typhoid intestinal perforation in children, under 18 years old, in sub-Saharan Africa published from January 1995 through June 2019. RESULTS Twenty-four papers from six countries were included. Reported mortality rates ranged from 4.6-75%, with 16 of the 24 studies between 11 and 30%. Thirteen papers included postoperative morbidity rates, ranging from 16-100%. The most documented complications included surgical site infections, intra-abdominal abscesses, and enterocutaneous fistulas. High mortality rates can be attributed to late presentation to tertiary centers, sepsis and electrolyte abnormalities requiring preoperative resuscitation, prolonged perforation-to-surgery interval, and lack of access to critical care or an intensive care unit postoperatively. CONCLUSIONS Current estimates of mortality related to typhoid intestinal perforation among children in sub-Saharan Africa remain unacceptably high. Prevention of typhoid fever is essential to reduce mortality, with the ultimate goal of a comprehensive approach that utilizes vaccination, improvements in water, sanitation, and hygiene, and greater access to surgical care.

Abstract
AIM Intestinal tuberculosis (ITb) and Crohn's disease (CD) mimic each other often leading to misdiagnosis. We evaluated the difference between ITb and CD using the extent of apoptosis in peripheral blood lymphocytes. METHODS CD4+ cells as a percentage of the lymphocytes and viable, dead, total apoptotic, early apoptotic, and late apoptotic CD4+ cells were assessed in the peripheral blood by flow cytometry in healthy controls and patients with confirmed active ITb and CD prior to initiating therapy. Early apoptotic and total apoptotic cells were further expressed as a proportion of the percentage of CD4+ cells. RESULTS The percentages of CD4+ cells (6.5 [3.0, 8.7] vs. 13.40 [10.15, 13.40]; p < 0.001), total apoptotic cells (0.13 [0.0, 0.22] vs. 0.08 [0.0, 0.21]; p = 0.045), early apoptotic (1.24 [0.55, 2.54] vs. 0.71 [0.40, 1.30]; p = 0.037), and the proportion of the latter two parameters (17.18 [5.61, 57.33] vs. 4.84 [2.71, 9.83]; p-value 0.039) and (17.18 [7.4, 67.50] vs. 5.51 [3.10, 11.03]; p-value 0.036) were significantly different between patients with ITb and CD. The best sensitivity, specificity, and positive and negative predictive values for the diagnosis of ITb were seen with the CD4+ cell percentage (82.6%, 82.4%, 86.4%, 77.8%, respectively) and the proportion of early apoptotic cells (73.9%, 70.6%, 77.3%, 66.7%, respectively). CONCLUSION CD4+ cells as a percentage of peripheral blood lymphocytes and the proportion of early apoptotic CD4+ cells show promise to diagnostic differentiation between ITb and CD.

Abstract
To analyze the clinical characteristics of intestinal tuberculosis (ITB), pay attention to the diagnostic value of endoscopy and mucosal biopsy, improve the recognition of atypical manifestations of ITB under endoscopy, and reduce misdiagnosis and missed diagnosis.The clinical data of 10 patients who were hospitalized in Changzhou second people's Hospital and finally diagnosed as ITB from January 1, 2015 to present were analyzed retrospectively. The basic information, medical history, clinical manifestations and computed tomography (CT), endoscopy of the patients was analyzed retrospectively. The results of pathological examination were analyzed and sorted out.Among the 10 patients, the ratio of male to female was 7:3, 10 (100%) had abdominal pain, 3 (30%) had diarrhea and 2 (20%) had bloody stool. The positive rate of tuberculosis T cell test was 75% (6/8), the diagnostic rate of chest high resolution CT was 60%, and the abnormal rate of abdominal high-resolution CT was 66.7% (6/9). Colonoscopy showed that the lesions mainly involved ileocecum (70%) and ascending colon (60%). Most of the lesions were intestinal stenosis (60%) and circular ulcer (50%). In a few cases, cold abscess (20%) and scar diverticulum (10%). Most of the pathological manifestations were granuloma formation and multinucleated giant cells (60%). The detection rate of caseous granuloma was 20%.The general condition and clinical manifestations of patients with ITB are not specific. Endoscopy and mucosal biopsy are of great significance for its diagnosis. The clinical manifestations and endoscopy of some patients showed atypical signs. Therefore, the combination of multi-disciplinary team models and the enhancement of clinician's recognition of the characteristics of endoscopic examination of ITB can improve us the diagnosis level of ITB.

Abstract
This review article discusses the challenges of making a firm histopathological diagnosis of inflammatory bowel disease (IBD) on biopsy and resection material and the importance of its distinction from a range of other inflammatory and infective conditions that may closely mimic IBD. In many cases, the diagnosis of ulcerative colitis or Crohn's disease is straightforward, especially when patients have a typical presentation and characteristic histopathological features. Knowledge of the full clinical history is very important, particularly past and recent medical history, drug history, foreign travel, or known contact with individuals with specific infection. Discussion of all cases of suspected IBD within a multidisciplinary team meeting is required to ensure that clinical, radiological, and pathological features can be correlated. Mimics of IBD can be divided into 4 categories: 1) those due to specific infection, 2) those due to a specific localized inflammatory process, 3) those due to iatrogenic causes, and 4) other rarer causes. Accurate diagnosis of IBD and exclusion of these mimics are crucial for patient management. Once a diagnosis of IBD has been proffered by a pathologist, it is very difficult to "undiagnose" the condition when an alternative diagnosis or "mimic" has been subsequently identified. The histological diagnosis of each of these IBD mimics is discussed in detail, with guidance on how to avoid the pitfall of missing these sometimes very subtle and "difficult to diagnose" conditions.

Abstract
The diagnosis of abdominal tuberculosis (TB) is challenging, and the prevalence of abdominal TB in children is likely underestimated. It may present with nonspecific abdominal symptoms and signs, but children who present with pulmonary TB may have additional abdominal subclinical involvement. Diagnosis is specifically challenging because none of the available diagnostic tools provide adequate sensitivity and specificity. In this review, we summarize the best available evidence on abdominal TB in children, covering the epidemiology, pathogenesis, clinical presentation, diagnosis, and treatment. We propose a diagnostic approach that could be followed for symptomatic children. We believe that a combination of investigations could be useful to both aid diagnosis and define the extent of the disease, and we propose that abdominal ultrasound should be used more frequently in children with possible TB and any abdominal symptoms. This neglected disease has received little attention to date, and further research is warranted.

Abstract
Differentiating Crohn’s disease (CD) from intestinal tuberculosis (ITB) is a diagnostic dilemma, particularly in regions where ITB is prevalent and CD incidence is increasing, because both diseases can present quite similarly, and diagnostic tests to identify Mycobacterium tuberculosis in tissue samples have rather poor sensitivity. Studies that were conducted to determine the factors that differentiate CD from ITB identified some significant characteristics, but none of those characteristics are exclusive to either ITB or CD. Many diagnostic models or scoring systems that use one to several diagnostic parameters have been proposed to help distinguish these two intestinal diseases. Early models consisted of parameters common to routine clinical practice, such as clinical features, and endoscopic and pathologic findings. The later models also include more advanced diagnostic parameters like high-resolution imaging and serological testing. However, the number and types of parameters differ among diagnostic models, and the systems used to calculate scoring also vary from model to model. Enhanced awareness and understanding of the currently available diagnostic models will help physicians determine which model(s) is/are most suitable for differentiating CD from ITB in their clinical practice.

Abstract
Background/Aims Opioid-induced bowel dysfunction includes nausea, vomiting, constipation and abdominal distension. We describe patients presenting with gastrointestinal (GI) ulcers and ulcerated strictures secondary to opioid abuse, an entity not well described in literature. Methods This retrospective observational study included patients with opioid abuse gastroenteropathy presenting to Dayanand Medical College and Hospital, Ludhiana, India between January 2013 and December 2018. Opioid abuse gastroenteropathy was defined as gastric or small bowel ulcers and ulcerated strictures in patients abusing opioids, where all other possible etiologies of GI ulcers/strictures were excluded. Clinical, biochemical, endoscopic, radiological and histological parameters as well as response to treatment were assessed. Results During the study period, 20 patients (mean age, 38.5±14.2 years; 100% males) were diagnosed to have opioid induced GI ulcers and/or ulcerated strictures. The mean duration of opioid consumption was 6.2±3.4 years. The mean duration of symptoms at presentation was 222.1±392.3 days. Thirteen patients (65%) had gastroduodenal involvement, 6 (30%) had a jejunoileal disease and 1 (5%) had an ileocecal stricture. Two patients (10%) presented with upper GI bleeding, 11 (55%) had features of gastric outlet obstruction and 7 (35%) presented with small bowel obstruction. Abdominal pain and iron deficiency anemia were the most common presentations. Only 1 patient (5%) responded to proton pump inhibitors, 3 (15%) had a lasting response to endoscopic balloon dilatation, while all other (80%) required surgical intervention. Conclusions Opioid abuse gastroenteropathy presents as ulcers and ulcerated strictures which respond poorly to medical management and endoscopic balloon dilatation. A majority of these cases need surgical intervention.

Abstract
PURPOSE To clarify unique non-contrast CT (NCCT) characteristics for early recognition of Schistosomal associated appendicitis (SAA) differentiating from Non-schistosomal associated appendicitis (NSA). MATERIAL AND METHODS Clinical and pathological data of 50 cases with SAA and 60 cases with NSA who underwent emergency appendectomy were retrospectively compared to pre-surgical NCCT features such as direct and indirect signs of acute appendicitis as well as appendicoliths, colon calcifications as diagnostic criteria. Statistical methods such as Chi-square (χ2), t-tests, Principal component analysis (PCA), Binary Logistic regression (LR) and Factor Analysis (FA) were utilized to observe differences and isolate recognizable CT features of SAA. Pre and post hoc diagnostic performance of all criteria was calculated as sensitivity, specificity, and the Odds Ratio (OR). RESULTS Age > 50 years, diameter > 13 mm, pneumatosis, peri appendiceal abscess, focal wall defect, perforation; Orbital, linear and point types of appendicular wall calcifications; sigmoid colon and cecal curvilinear calcifications were observed as unique characteristics with a sensitivity of 84-95% and specificity of 91-98% in predicting SAA by OR of 6.2 times. Pre and post hoc hypothetical analysis did not show any significance for all other factors. CONCLUSION Factors such as elderly age, CT features such as larger appendicular diameter, appendicular wall calcifications along with sigmoid colon, and cecal calcifications, signs of perforation or abscess are characteristic for early recognition of SAA.

Abstract
BACKGROUND The differentiation between untypical intestinal tuberculosis (UITB) and untypical Crohn's disease (UCD) is a challenge. AIMS To analyze phenotypic variables and propose a novel prediction model for differential diagnosis of two conditions. METHODS A total of 192 patients were prospectively enrolled. The clinical, laboratory, endoscopic, and radiological features were investigated and subjected to univariable and multivariable analyses. The final prediction model for differentiation between UCD and UITB was developed by logistic regression analysis and Fisher discriminant analysis on the training set. The same discriminant function was tested on the validation set. RESULTS Twenty-five candidates were selected from 52 phenotypic variables of typical Crohn's disease (TCD), UCD, and UITB patients. UCD's variables overlapped with both TCD and UITB. The percentages of tuberculosis history, positive PPD, and positive T-SPOT result in UCD were all significantly higher than that in TCD (11.6% vs. 0.0%, 27.9% vs. 0.0%, 25.6% vs. 4.5%, respectively, P < 0.05). The regression equations and Fisher discriminant function for discrimination between UCD and UITB were developed. In the training data, the area under the receiver operating characteristic of equations was 0.834, 0.69, and 0.648 in the clinical-laboratory, endoscopic, and radiological model, respectively. The accuracy of Fisher discriminant function for discrimination was 86% in UCD and 73% in UITB in the validation data. CONCLUSIONS Phenotypes of UCD patients in TB-endemic countries may be associated with TB infection history. Fisher discriminant analysis is a good choice to differentiate UCD from UITB, which is worthy of verification in clinical practice.

Abstract
INTRODUCTION Overlap of clinical, endoscopic and radiographic features, coupled with a poor microbiological yield makes differentiating Crohn's disease (CD) from intestinal tuberculosis (ITB) challenging. A potential histological differentiating mechanism is the use of immunohistochemical staining for the mesenchymal stem cell marker CD73, as a pilot study showed ITB but not CD granulomas stained positive for this marker. The aim of this study was to assess the value of CD73 in differentiating ITB from CD granulomas in a South African cohort. METHODS Patients with confirmed CD or ITB were identified from a pathology database. Tissue sections were reviewed by a pathologist to confirm the presence of granulomas. These were then stained with a mouse monoclonal anti-CD73 antibody. The slides were examined together by a pathologist and gastroenterologist in a blinded manner for anti-CD73 staining around granulomas. RESULTS Ninety six cases were available for analysis; 50 cases of ITB and 46 cases of CD. Thirty percent of CD granulomas (14/46) stained positive for CD73, whereas CD73 positivity was seen in 52% (26/50) of cases of ITB. This was statistically significant (OR 2.48, 95% CI 1.1-5.72, p = .03). The area under the curve (AUC) was 0.61. Sensitivity of CD73 in predicting ITB was 52% and specificity was 70%. Overall CD73 staining of granulomas correctly classified only 60% of cases. CONCLUSIONS In our study we have shown that significantly more patients with ITB express CD73 in their granulomas than those with CD. However the relatively poor sensitivity, specificity and AUC make this test unlikely to be of value in our clinical practice.

Abstract
Introduction Tuberculosis is a disease that has been affecting mankind since time immemorial and it still continues to be a global health concern. Objective of the study was to evaluate the burden, clinical profile, diagnosis and diagnostic difficulties and outcome of abdominal tuberculosis (AbT) in non human immunodeficiency virus (HIV) infected adults in the department of gastroenterology at a tertiary care hospital over a period of two years. Material & methods It was an observational study and the study period was from January 2016 till January 2018. The patients who were sero positive for HIV virus were excluded from the study. Results The number of patients hospitalized during the period of 2016-2018 with abdominal tuberculosis was 58. The burden of tuberculosis of indoor patients was 1.3 cases per every 100 patients admitted. Presenting complaint of most of these patients [61%] was abdominal pain. Constitutional symptoms like fever; weight loss and loss of appetite were present in only 40% of the patients. Ascites was the presenting sign in around 45% of the patients. Peritoneum was the most common site of involvement [27 out of 58]. Almost all of these patients [25 out of 27] presented with abdominal pain and abdominal distension. Intestine was the second most common site. Ileocaecal involvement was present in fourteen patients, while other areas of colon were involved in five patients. All the 58 patients were given anti tubercular therapy. There was complete resolution of tuberculosis in 91% of cases [53 out of 58 patients]. Six patients developed drug induced liver injury. Death occurred in two patients who had disseminated tuberculosis. Conclusion Although the burden of the disease remains the same, availability of newer investigations has aided in its early diagnosis and availability of good drugs has reduced the mortality and morbidity.

Abstract
Differentiating Crohn’s disease (CD) and intestinal tuberculosis (ITB) has remained a dilemma for most of the clinicians in the developing world, which are endemic for ITB, and where the disease burden of inflammatory bowel disease is on the rise. Although, there are certain clinical (diarrhea/hematochezia/perianal disease common in CD; fever/night sweats common in ITB), endoscopic (longitudinal/aphthous ulcers common in CD; transverse ulcers/patulous ileocaecal valve common in ITB), histologic (caseating/confluent/large granuloma common in ITB; microgranuloma common in CD), microbiologic (positive stain/culture for acid fast-bacillus in ITB), radiologic (long segment involvement/comb sign/skip lesions common in CD; necrotic lymph node/contiguous ileocaecal involvement common in ITB), and serologic differences between CD and ITB, the only exclusive features are caseation necrosis on biopsy, positive smear for acid-fast bacillus (AFB) and/or AFB culture, and necrotic lymph node on cross-sectional imaging in ITB. However, these exclusive features are limited by poor sensitivity, and this has led to the development of multiple multi-parametric predictive models. These models are also limited by complex formulae, small sample size and lack of validation across other populations. Several new parameters have come up including the latest Bayesian meta-analysis, enumeration of peripheral blood T-regulatory cells, and updated computed tomography based predictive score. However, therapeutic anti-tubercular therapy (ATT) trial, and subsequent clinical and endoscopic response to ATT is still required in a significant proportion of patients to establish the diagnosis. Therapeutic ATT trial is associated with a delay in the diagnosis of CD, and there is a need for better modalities for improved differentiation and reduction in the need for ATT trial.

Abstract
A young patient had serious hematochezia for nearly 2 months without obvious cause. Abdominal CT images showed rare features such as serious hemorrhage and multiple miliary nodules in the small bowel. The colonoscopy showed multiple lymphoid follicles in the terminal ileum. The laparotomy showed adverse adhesion in the abdominal cavity and multiple miliary noduli in the surfaces of small bowel wall. The pathology suggested tuberculosis. This patient received anti-TB therapy and the condition improved gradually. There are many variants of GI tuberculosis demonstrating uncommon and rare imaging features. It turned to be difficult in diagnosis when it showed the rare appearance, such as the great amount of intestinal bleeding and multiple noduli in our case. The reason why gastrointestinal bleeding might be attributed to the invasiveness of submucosal vessels by the tuberculosis bacteria. And the multiple noduli on the bowel wall might be the granuloma formation. Therefore, from the experience of our case, gastrointestinal tract might also be the first and only involved site, and it may cause great amount of bleeding to a life danger, even in young people.

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.

Aliment Pharmacol Ther 2018; 47:1367-1374. [PMID: 29572889 DOI: 10.1111/apt.14617] [Citation(s) in RCA: 43] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2017] [Revised: 08/30/2017] [Accepted: 02/26/2018] [Indexed: 12/16/2022]
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
Tuberculosis involvement of the gastrointestinal tract, peritoneum, and associated viscera is an uncommon but well described entity. While peritoneal tuberculosis and tuberculous enteritis are more common, involvement of the esophagus, stomach, colon, rectum, anus, liver, bile ducts, gallbladder, and pancreas can occur. Diagnosis is challenging as cases often mimic neoplasm or inflammatory bowel disease. In this review we outline the pathogenesis, clinical presentation, diagnostic testing, and treatment strategies pertaining to such cases.

Abstract
Background/aims As increasing numbers of Crohn's disease (CD) cases are being recognized in India, so the differential diagnosis of CD and gastrointestinal tuberculosis (GITB) is becoming increasingly important. If patients are misdiagnosed with GITB, toxicity may result from unnecessary anti-TB therapy and treatment of the primary disease (ie, CD) gets delayed. We therefore aimed to assess the accuracy of various parameters that can be used to predict GITB diagnosis at index evaluation. Materials and methods This was a prospective, unicentric, observational study carried out in the gastroenterology department of a tertiary care hospital between August 2011 and January 2013. Patients who presented to our hospital and were suspected of having GITB were included in our study. Patients were then followed up over a 6-month period. Statistical analysis Chi-square test was used to analyze the data. Results Of the 69 patients with GITB, 49 (71.01%) had thickening of the involved part of the colon and 33 (47.83%) had abdominal lymphadenopathy. The ileocecal valve was involved in 58 patients (84.05%) Histological detection of granulomas had 78.95% specificity, 36.23% sensitivity, and 51.40% accuracy. Tuberculosis polymerase chain reaction was found to have 78.95% specificity, 71.01% sensitivity, and 73.83% accuracy. BACTEC-MGIT culture was found to have 100% specificity, 20.29% sensitivity, and 48.60% accuracy. Conclusion Although histology is helpful in ruling out other conditions, TB-specific findings such as caseating granuloma and acid-fast bacilli are rarely seen. Instead, tuberculosis polymerase chain reaction has the highest diagnostic accuracy followed by BACTEC culture.

Abstract
Strictures of the small intestine have been attributed many causes of Crohn's disease, nonsteroidal anti-inflammatory drugs, neoplastic, post-surgical, and corrosive ingestion. Opium as a cause of small intestine strictures has not been described. Six cases of opium addicts diagnosed with small intestine strictures were selected after excluding the possible etiology of strictures. Investigations like upper gastrointestinal endoscopy, colonoscopy (in patients with small intestinal obstruction), barium meal follow-through, and histopathology of strictures were done in all patients. Among the six cases, two patients were diagnosed with small intestinal obstruction and four patients with gastric outlet obstruction. Histopathology of the strictures revealed marked thickening of submucosa with infiltration by lymphocytes, plasma cells, and plenty of eosinophils. There was dilatation of vessels and lymphatics. The granulomatous reaction was not seen. These histological features are suggestive of concentric fibrous thickening in submucosa with stricture formation possibly as a result of drug abuse like opioids and opioid-like products resulting in transient ischemia of the small intestine leading to fibrosis. Patients were managed by surgery and deaddiction treatment was given to prevent further complications. Opium and opioid-like drugs can cause small intestinal strictures causing ulceration and fibrosis in opioid-dependent patients.

Abstract
Gastric biopsies are routinely obtained from patients with symptoms related to the gastrointestinal tract and, as a result, a variety of histologic changes are observed in patients with or without endoscopic evidence of mucosal injury. Although Helicobacter pylori-related gastritis is still common, several other patterns of mucosal injury are increasingly encountered. These patterns of injury are classified based on the nature and distribution of inflammation, location of epithelial cell injury, presence of crystal or pigment deposition, and/or other unique features. This article discusses each of these patterns and provides a differential diagnosis for each.

Abstract
AIM To investigate the temporal trends in the misdiagnosis rate between Crohn's disease (CD) and intestinal tuberculosis (ITB) in South Korea. METHODS We retrospectively reviewed the medical records of patients managed for CD or ITB at Asan Medical Center, a tertiary referral hospital, Seoul, Korea between 1996 and 2014. The temporal trends in the misdiagnosis rates between the two diseases were analyzed. The demographic and clinical characteristics were compared between CD patients who were initially misdiagnosed as ITB (final CD group) and vice versa (final ITB group). Final diagnostic criteria for ITB and medication for CD before definite diagnosis of TB were also analyzed in final ITB group. RESULTS In total, 2760 patients were managed for CD and 772 patients for ITB between 1996 and 2014. As well, 494 of the 2760 CD patients (17.9%) were initially misdiagnosed as ITB and 83 of the 772 ITB patients (10.8%) as CD. The temporal trend in misdiagnosing CD as ITB showed a decrease (OR = 0.89, 95%CI: 0.87-0.91, P < 0.001), whereas the temporal trend in misdiagnosing ITB as CD showed an increase (OR = 1.06, 95%CI: 1.01-1.11, P = 0.013). Age at diagnosis, presenting symptoms, and proportion of patients with active/past perianal fistula and active/inactive pulmonary tuberculosis (TB) were significantly different between final CD group and final ITB group. Forty patients (48.2%) in final ITB group were diagnosed by favorable response to empirical anti-TB treatment. Seventeen patients (20.5%) in final ITB group had inappropriately received corticosteroids and/or thiopurines due to misdiagnosis as CD. However, there were no mortalities in both groups. CONCLUSION Cases of CD misdiagnosed as ITB have been decreasing, whereas cases of ITB misdiagnosed as CD have been increasing over the past two decades.

Abstract
BACKGROUND Frequent relapses sometimes necessitating hospitalization and the absence of pharmacological cure contribute to substantial healthcare costs in inflammatory bowel diseases (IBDs). The costs of health care in Indian patients with IBD are unknown. AIM To evaluate the annual costs for treating Crohn's disease and ulcerative colitis. METHODS A prevalence-based, micro-costing method was used to assess the components of annual costs in a prospective, observational study conducted in a tertiary healthcare center enrolled over a 24-month period beginning of July 2014. RESULTS At enrollment, 43/59 (72.88%) patients with UC and 18/25 (72%) with CD were in remission. The annual median (IQR) cost per UC and CD patient in remission was INR 43,140 (34,357-51,031) [USD $707 (563-836)] and INR 43,763.5 (32,202-57,372) [USD $717 (527-940)], respectively, and in active disease was INR 52,436.5 (49,229-67,567.75) [$859 (807-1107)] and INR 72,145 (49,447-92,212) [USD $1182 (811-1512)], respectively. Compared with remission, active disease had a 1.4-fold higher cost for CD as compared to UC. In both groups, the greatest component of direct costs was drugs. Thirteen (22%) and 7 (28%) patients with UC and CD needed hospitalization accounting for 23.1 and 20.4% of the total costs, respectively. At one year, direct costs surmounted indirect costs in UC and CD (p < 0.001). Productivity losses contributed to 18.5 and 16% of the overall costs for UC and CD, respectively. CONCLUSION This first, panoptic, health economic study for IBD from India shows that the costs are driven by medication, productivity losses, and not merely hospitalization alone.

Abstract
AIM To investigated clinical, endoscopic and histopathological parameters of the patients presenting with ileocecal ulcers on colonoscopy.
METHODS Consecutive symptomatic patients undergoing colonoscopy, and diagnosed to have ulcerations in the ileocecal (I/C) region, were enrolled. Biopsy was obtained and their clinical presentation and outcome were recorded.
RESULTS Out of 1632 colonoscopies, 104 patients had ulcerations in the I/C region and were included in the study. Their median age was 44.5 years and 59% were males. The predominant presentation was lower GI bleed (55, 53%), pain abdomen ± diarrhea (36, 35%), fever (32, 31%), and diarrhea alone (9, 9%). On colonoscopy, terminal ileum was entered in 96 (92%) cases. The distribution of ulcers was as follows: Ileum alone 40% (38/96), cecum alone 33% (32/96), and both ileum plus cecum 27% (26/96). The ulcers were multiple in 98% and in 34% there were additional ulcers elsewhere in colon. Based on clinical presentation and investigations, the etiology of ulcers was classified into infective causes (43%) and non-infective causes (57%). Fourteen patients (13%) were diagnosed to have Crohn’s disease (CD).
CONCLUSION Non-specific ileocecal ulcers are most common ulcers seen in ileo-cecal region. And if all infections are clubbed together then infection is the most common (> 40%) cause of ulcerations of the I/C region. Cecal involvement and fever are important clues to infective cause. On the contrary CD account for only 13% cases as a cause of ileo-cecalulcers. So all symptomatic patients with I/C ulcers on colonoscopy are not Crohn’s.

Abstract
OBJECTIVE To describe characteristics, presentation, time to diagnosis and diagnostic findings of patients with intestinal tuberculosis (ITB) in a low-burden country. METHOD Retrospective study of 61 consecutive ITB patients diagnosed between 2008 and 2014 at a large East London hospital. RESULTS Forty of sixty-one patients were male. Mean age was 34.6 years. 93% of patients were born abroad, mostly from TB-endemic areas (Indian subcontinent: 88%, Africa: 9%). 25% had concomitant pulmonary TB. Median time from symptom onset to ITB diagnosis was 13 weeks (IQR 3-26 weeks). Ten patients were initially treated for IBD, although patients had ITB. The main sites of ITB involvement were the ileocaecum (44%) or small bowel (34%). Five patients had isolated perianal disease. Colonoscopy confirmed a diagnosis of ITB in 77% of those performed. 42 of 61 patients had a diagnosis of ITB confirmed on positive histology and/or microbiology. CONCLUSION Diagnosis of ITB is often delayed, which may result in significant morbidity. ITB should be excluded in patients with abdominal complaints who come from TB-endemic areas to establish prompt diagnosis and treatment. Diagnosis is challenging but aided by axial imaging, colonoscopy and tissue biopsy for TB culture and histology.

Abstract
BACKGROUND To analyse our experience with acute presentations of abdominal tuberculosis (TB) in children for early diagnosis and management. MATERIALS AND METHODS From December 2010 to April 2016, available electronic and operation theatre (OT) records of 17 patients with confirmed diagnosis of abdominal TB were analysed retrospectively. Parameters reviewed were age, sex, presentations, diagnostic investigations, surgery/intervention performed, final outcome and follow-up. RESULTS Out of 17 patients, 6 (35.3%) were already operated elsewhere. The duration of symptoms ranged from 4 to 58 weeks. Abdominal pain was present in all cases whereas 11 (64.7%) had abdominal distension, 16 (94.1%) fever, 14 (82.3%) ascites, 9 (52.9%) vomiting, 14 (82.3%) weight loss, 6 (35.3%) anorexia and 4 (23.5%) night sweat. All patients needed surgical intervention for definitive diagnosis. Thirteen (76.5%) out of 17 patients managed by staged surgery and primary anastomosis/repair/adhesiolysis were done in 4 (23.5%) patients. The main post-operative problems were wound infections (8; 47.1%), subacute bowel obstruction (6; 35.3%) and chest infections (12; 70.6%). Follow-up period ranged from 3 months to 5.5 years. CONCLUSION Abdominal TB should always be considered in differential diagnosis in children presenting with abdominal pain/distension, fever and ascites or with abdominopelvic mass. Recurrent bowel obstruction or anastomotic disruptions also give clues of its diagnosis. A careful history of illness, high index of suspicion, ascitic fluid adenosine deaminase or polymerase chain reaction for Mycobacterium needed for early diagnosis. Prompt minimal surgical interventions, preferred diversion over primary anastomosis, algorithmic vigilant post-operative care and early antitubercular treatment required for success in acute crisis.

Accuracy of computed tomographic features in differentiating intestinal tuberculosis from Crohn's disease: a systematic review with meta-analysis. Intest Res 2017; 15:149-159. [PMID: 28522943 PMCID: PMC5430005 DOI: 10.5217/ir.2017.15.2.149] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/04/2016] [Revised: 09/21/2016] [Accepted: 09/21/2016] [Indexed: 12/16/2022] Open
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
Differentiation of small bowel tuberculosis (SBTB) from Crohn’s disease (CD) is a diagnostic challenge. We studied 52 patients with suspected SBTB or CD with terminal ileal involvement, who were prospectively enrolled. After confirming patency of the gastrointestinal tract, 26 patients underwent capsule endoscopy (CE). A final diagnosis of CD was found in 18 patients and SBTB in eight patients. All SBTB patients had involvment of the ileocecal valve (ICV) with large (n = 6) and aphthous (n = 2) ulcers in the ileal segment. In CD, ICV involvement was seen in five (33%) patients. Large and aphthous ulcers were observed in seven (47%) and 15 (100%) patients, respectively. On comparison with CD, patients with SBTB had increased frequency of ICV involvement ( P = 0.002) and lesser frequency of aphthous ulcers ( P = 0.007). CE can help in differentiating CD from SBTB by the position of its involvement and the type of ulcers present.

Meta-Analytic Bayesian Model For Differentiating Intestinal Tuberculosis from Crohn's Disease. Am J Gastroenterol 2017; 112:415-427.

Abstract
OBJECTIVES Distinguishing intestinal tuberculosis (ITB) from Crohn's disease (CD) is difficult, although studies have reported clinical, endoscopic, imaging, and laboratory findings that help to differentiate these two diseases. We aimed to produce estimates of the predictive power of these findings and construct a comprehensive model to predict the probability of ITB vs. CD. METHODS A systematic literature search for studies differentiating ITB from CD was conducted in MEDLINE, PUBMED, and EMBASE from inception until September 2015. Fifty-five distinct meta-analyses were performed to estimate the odds ratio of each predictive finding. Estimates with a significant difference between CD and ITB and low to moderate heterogeneity (I2<50%) were incorporated into a Bayesian prediction model incorporating the local pretest probability. RESULTS Thirty-eight studies comprising 2,117 CD and 1,589 ITB patients were included in the analyses. Findings in the model that significantly favored CD included male gender, hematochezia, perianal disease, intestinal obstruction, and extraintestinal manifestations; endoscopic findings of longitudinal ulcers, cobblestone appearance, luminal stricture, mucosal bridge, and rectal involvement; pathological findings of focally enhanced colitis; and computed tomographic enterography (CTE) findings of asymmetrical wall thickening, intestinal wall stratification, comb sign, and fibrofatty proliferation. Findings that significantly favored ITB included fever, night sweats, lung involvement, and ascites; endoscopic findings of transverse ulcers, patulous ileocecal valve, and cecal involvement; pathological findings of confluent or submucosal granulomas, lymphocyte cuffing, and ulcers lined by histiocytes; a CTE finding of short segmental involvement; and a positive interferon-γ release assay. The model was validated by gender, clinical manifestations, endoscopic, and pathological findings in 49 patients (27 CD, 22 ITB). The sensitivity, specificity, and accuracy for diagnosis of ITB were 90.9%, 92.6%, and 91.8%, respectively. CONCLUSIONS A Bayesian model based on the meta-analytic results is presented to estimate the probability of ITB and CD calibrated to local prevalence. This model can be applied to patients using a publicly available web application.

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
There is rising incidence and prevalence of inflammatory bowel disease (IBD) in India topping the Southeast Asian (SEA) countries. The common genes implicated in disease pathogenesis in the West are not causal in Indian patients and the role of “hygiene hypothesis” is unclear. There appears to be a North-South divide with more ulcerative colitis (UC) in north and Crohn’s disease (CD) in south India. IBD in second generation Indian migrants to the West takes the early onset and more severe form of the West whereas it retains the nature of its country of origin in migrants to SEA countries. The clinical presentation is much like other SEA countries (similar age and sex profile, low positive family history and effect of smoking, roughly similar disease location, use of aminosalicylates for CD, low use of biologics and similar surgical rates) with some differences (higher incidence of inflammatory CD, lower perianal disease, higher use of aminosalicylates and azathioprine and lower current use of corticosteroids). UC presents more with extensive disease not paralleled in severity clinically or histologically, follows benign course with easy medical control and low incidence of fulminant disease, cancer, complications, and surgery. UC related colorectal cancer develop in an unpredictable manner with respect to disease duration and site questioning the validity of strict screening protocol. About a third of CD patients get antituberculosis drugs and a significant number presents with small intestinal bleed which is predominantly afflicted by aggressive inflammation. Biomarkers have inadequate diagnostic sensitivity and specificity for both. Pediatric IBD tends to be more severe than adult. Population based studies are needed to address the lacunae in epidemiology and definition of etiological factors. Newer biomarkers and advanced diagnostic techniques (in the field of gastrointestinal endoscopy, molecular pathology and genetics) needs to be developed for proper disease definition and treatment.
