RESUMO
INTRODUCTION: Abdominal tuberculosis presents in a variety of ways. Different testing modalities must be applied in addition to having a high clinical suspicion to diagnose and initiate therapy. Medications have a good response; however, morbidity has been seen following surgical management of complicated presentations like intestinal obstruction and perforation. There is a paucity of studies in the pediatric age group which evaluate response to the different treatment regimen and identify factors associated with poorer outcomes in children with abdominal tuberculosis. METHODS: Patient records of 75 children with abdominal tuberculosis at a single center were evaluated using a questionnaire, covering a 14-year period from 2007 to 2021. Demographic features, presenting signs and symptoms, investigations and treatment details were studied. In- person or telephonic follow-up was conducted to identify treatment outcomes. RESULTS: Incidence of abdominal TB was 7%, of all TB children with a mean age of 10.1 years. Mesenteric lymph nodes were involved in 67% and small intestine in 33% cases. Surgery was required in 22 children. 85% children completed treatment. Small intestine involvement had higher probability of undergoing surgery. Of the 70 children with complete follow up, 64 were well and 6 children succumbed to the disease. Older age, small intestine involvement and surgery were independently associated with higher mortality. CONCLUSION: Intestinal involvement is associated with greater need for surgical intervention and greater mortality. Adolescents have poorer outcomes. Further studies are required focusing on these individual subgroups to understand the patterns of presentation, causes for mortality and prevention. LEVEL OF EVIDENCE: Level 5.

BACKGROUND: Abdominal tuberculosis presenting as acute surgical emergency continues to be a major issue in developing countries including India. Being an indolent disease with varied presentation, there is a need to describe the epidemiology, clinicopathological nature of the disease. Hence, this series was conducted with the aim of describing our institutional experience in the management of abdominal tuberculosis presenting as acute surgical emergency, outlining the epidemiology, management aspects and the analysis of risk factors for poor outcome in our population. METHODS: This was a descriptive series of patients operated for abdominal tuberculosis presenting as acute surgical emergency at a tertiary care hospital in Eastern India from January 2021 to January 2022. All consecutive patients presenting with intestinal obstruction or peritonitis who underwent laparotomy with intra operative and histopathological finding suggestive of tuberculosis were taken for the study. RESULTS: A total of 30 patients with acute abdominal tuberculosis were included in the study. 56.7% of patients were males; the mean age of presentation was 43 years with majority of patients in the younger to middle age groups. Most (80%) patients were from rural areas with limited access to healthcare. One patient had co-infection with HIV. Five patients had diabetes and six patients had hypertension as co-morbidities. 73.3% of patients had primary intestinal tuberculosis. Majority (76.7%) presented with acute intestinal obstruction. All patients had colicky abdominal pain as a consistent feature. 40% of patients were anaemic and 70% had low serum albumin levels. The most common site of affection was Ileo-cecal region (73.3%) with stricture as the pathology. Segmental resection with end to end anastomosis was the most common procedure performed (46.7%). 26.7% of patients had an adverse post operative complication, and 23.3% had surgical site infection (SSI). The mortality rate in our series was 6.7%. Although coexisting SSI, co-morbidities were associated with increased mortality, it was not found to be statistically significant (p = 0.08). 16 patients were lost to follow up. CONCLUSION: Abdominal tuberculosis presenting as acute abdomen continues to challenge surgeons even in the 21st century. Majority in the developing countries present late with varied complications. A high index of clinical suspicion is required for timely diagnosis to reduce the mortality and morbidity of the disease.

BACKGROUND: The differentiation between intestinal tuberculosis (ITB) and Crohn's disease (CD) remains a challenge, particularly in areas where tuberculosis is highly prevalent. Previous studies have identified features that favour one diagnosis over the other. The aim of the study was to determine the accuracy of a standardized protocol in the initial diagnosis of CD versus ITB. METHODS: All patients with suspected ITB or CD were prospectively recruited. A standardized protocol was applied, and the diagnosis was made accordingly. The protocol consists of history and examination, ileocolonoscopy with biopsies, and tuberculosis workup. The diagnosis of probable ITB was made based on at least one positive finding. All other patients were diagnosed as probable CD. Patients were treated either with anti-tubercular therapy or steroids. Reassessment was then carried out clinically, biochemically, and endoscopically. In patients with suboptimal response, the treatment was either switched or escalated depending on the reassessment. RESULTS: 164 patients were recruited with final diagnosis of 30 (18.3%) ITB and 134 (81.7%) CD. 1 (3.3%) out of 30 patients with ITB was initially treated as CD. 16 (11.9%) out of 134 patients with CD were initially treated as ITB. The initial overall accuracy for the protocol was 147/164 (89.6%). All patients received the correct diagnosis by 12 weeks after reassessment. CONCLUSION: In our population, most patients had CD rather than ITB. The standardized protocol had a high accuracy in differentiating CD from ITB.

BACKGROUND/OBJECTIVES: Tuberculosis is a multisystem disease that might affect any organ. Abdominal tuberculosis (ABT) represents 5-17% from all extrapulmonary tuberculosis (EPT) sites. We aimed to study the clinical, laboratory and evolutionary features of ABT cases and to identify predictive factors associated with ABT. METHODS: We conducted a retrospective study including all patients hospitalized in the infectious diseases department for EPT between 1991 and 2019. We studied the characteristics of ABT cases, and we compared them with other EPT cases. RESULTS: We identified 519 patients with EPT, among whom 86 (16.6%) patients had ABT. There were 58 females (67.4%). Peritoneal tuberculosis was the most common clinical form of ABT (68.6%), followed by intestinal tuberculosis (18.6%). Patients aged 60 years and above were significantly less affected with ABT (odds ratio (OR) = 0.2; p = 0.001). The revealing systemic symptoms including fever (OR = 2.04; p = 0.006), weight loss (OR = 2.5; p < 0.001) and anorexia (OR = 1.7; p = 0.021) were significantly more frequent among ABT patients. Inflammatory markers including C-reactive protein levels (37 [10-89] mg/l vs 10 [4-57] mg/l; p < 0.001) and erythrocyte sedimentation rates (43 [15-95] mm/h vs 27 [15-60] mm/h; p = 0.044) were significantly higher among ABT cases. Multivariate logistic regression analysis showed that anorexia (adjusted OR (AOR) = 1.9; p = 0.015) and pulmonary involvement (AOR = 3.3; p = 0.002) were independent predictors of higher rate of ABT. Concomitant involvement of neuro-meningeal (AOR = 0.18; p = 0.001) and osteo-articular (AOR = 0.2; p = 0.01) sites, 40-59 (AOR = 0.2; p < 0.001) and ≥60 (AOR = 0.2; p < 0.001) age groups as well as hemoglobin rate (AOR = 0.7; p < 0.001) were independently associated with lower rate of ABT. CONCLUSIONS: Anorexia and pulmonary involvement were independent predictors of higher rate of ABT. Concomitant involvement of neuro-meningeal and osteo-articular sites, 40-59 and ≥60 age groups and hemoglobin rate were independently associated with lower rate of ABT.

BACKGROUND AND PURPOSE: abdominal tuberculosis (TB) is a common form of extrapulmonary TB but it is still a diagnostic dilemma in clinical practice. This study aimed to highlight the clinical features and diagnostic approaches for abdominal TB. METHODS: seventy cases of diagnosed abdominal TB were retrospectively collected between August 1st, 2015 and June 30th, 2020. They were classified as peritoneal TB, lymph node TB, gastrointestinal TB, visceral TB or mixed TB. RESULTS: eighteen patients were diagnosed with peritoneal TB, nine with lymph node TB, five with gastrointestinal TB, two with visceral TB and 36 with mixed TB. More than 65 % of the patients had tuberculosis of other sites except the abdomen. The median diagnosis time was 60 days. Ascites (58.6 %), abdominal distension (48.6 %), weight loss (44.3 %) and fever (42.9 %) were the most common symptoms. The overall microbiological and histological detection rates were 70.0 % and 38.6 %, respectively. The non-ascite samples yielded a higher microbiological confirmation rate (63.6 %) than the total samples (40.8 %). Diagnosis was confirmed histologically in 18 patients (69.2 %). Forty-five cases (64.3 %) were clinically diagnosed. Invasive procedures such as surgery (6/7), percutaneous biopsy (7/7) and endoscopy in lymph node TB (4/5) had high confirmation rates. CONCLUSIONS: the diagnosis of abdominal TB should be reached by a combination of clinical, laboratory, radiological, microbiological and pathological findings.

Tuberculosis (TB) once considered a disease of the developing world is infrequent in the developing world too. Its worldwide prevalence with a huge impact on the healthcare system both in economic and health terms has prompted the World Health Organization to make it a top priority infectious disease. Tuberculous infection of the pulmonary system is the most common form of this disease, however, extrapulmonary TB is being increasingly recognized and more often seen in immunocompromised situations. Gastrointestinal TB is a leading extrapulmonary TB manifestation that can defy diagnosis. Overlap of symptoms with other gastrointestinal diseases and limited accuracy of diagnostic tests demands more awareness of this disease. Untreated gastrointestinal TB can cause significant morbidity leading to prolonged hospitalization and surgery. Prompt diagnosis with early initiation of therapy can avoid this. This timely review discusses the epidemiology, risk factors, pathogenesis, clinical presentation, current diagnostic tools and therapy.

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.

OBJECTIVES: Abdominal tuberculosis (ATB) is the second most common type of extra-pulmonary tuberculosis. Though it does not usually pose a significant risk of infectivity, ATB can go unidentified and progress to disseminated infection. The aim of this study is to highlight the incidence and outcome of this infection in a tertiary care centre in the Kingdom of Saudi Arabia (KSA). METHODS: In this retrospective study, we included all ATB patients admitted to our centre between January 1 st, 2010 and December 31, 2018. A total of 42 patients with a median age of 49 (range 18-83 years, 78.6% males) were identified. RESULTS: The most common presentation was abdominal pain, weight loss, and abdominal distension. All the patients were HIV negative; however, 50% had a comorbid condition, mainly diabetes mellitus, chronic renal failure, and liver cirrhosis. Tuberculous peritonitis was the predominant type of ATB. Suspicious and potentially malignant abdominal masses appeared on the abdominal CT scans of six patients. This suggest that TB should be excluded in patients from endemic area presenting with abdominal masses. All patients received standard anti-tuberculous medication for an average duration of 7.4 months. The outcome was excellent with 88%% achieving complete response. Adjunctive corticosteroids were not used, and none of the patients had a surgical complication. CONCLUSION: The diagnosis of ATB is challenging. It can mimic inflammatory bowel disease in young populations and malignancy in middle-aged and elderly population. For this reason, a high index of suspicion with prompt treatment is required to improve the prognosis and prevent complications.

BACKGROUND: Data on external validation of models developed to distinguish Crohn's disease (CD) from intestinal tuberculosis (ITB) are limited. This study aimed to validate and compare models using clinical, endoscopic, and/or pathology findings to differentiate CD from ITB. METHODS: Data from newly diagnosed ITB and CD patients were retrospectively collected from 5 centers located in Thailand or Hong Kong. The data was applied to Lee, et al., Makharia, et al., Jung, et al., and Limsrivilai, et al. model. RESULTS: Five hundred and thirty patients (383 CD, 147 ITB) with clinical and endoscopic data were included. The area under the receiver operating characteristic curve (AUROC) of Limsrivilai's clinical-endoscopy (CE) model was 0.853, which was comparable to the value of 0.862 in Jung's model (p = 0.52). Both models performed significantly better than Lee's endoscopy model (AUROC: 0.713, p<0.01). Pathology was available for review in 199 patients (116 CD, 83 ITB). When 3 modalities were combined, Limsrivilai's clinical-endoscopy-pathology (CEP) model performed significantly better (AUROC: 0.887) than Limsrivilai's CE model (AUROC: 0.824, p = 0.01), Jung's model (AUROC: 0.798, p = 0.005) and Makharia's model (AUROC: 0.637, p<0.01). In 83 ITB patients, the rate of misdiagnosis with CD when used the proposed cutoff values in each original study was 9.6% for Limsrivilai's CEP, 15.7% for Jung's, and 66.3% for Makharia's model. CONCLUSIONS: Scoring systems with more parameters and diagnostic modalities performed better; however, application to clinical practice is still limited owing to high rate of misdiagnosis of ITB as CD. Models integrating more modalities such as imaging and serological tests are needed.

Introducción: La tuberculosis es una enfermedad reemergente, importante como causa mayor de incapacidad y muerte en muchas zonas del mundo. La tuberculosis intestinal representa 11 por ciento de todas las formas extrapulmonares; 0,5 por ciento de todos los casos nuevos de y el 10 al 15 por ciento en los no infectados por el VIH. En el municipio Tunas se notificó el caso de un adolescente de 17 años, masculino, al que se le diagnostica esta enfermedad luego de haber presentado síntomas de dolor abdominal recurrente durante de varios meses antes del diagnóstico. Objetivo: Actualizar la información sobre el diagnóstico y tratamiento de la tuberculosis intestinal. Métodos: Se realizó una revisión bibliográfica sobre tuberculosis intestinal con la literatura encontrada en bases de datos disponibles en la red Infomed: PubMed, Hinari, The Cochrane Library, SciELO, MEDLINE y MedicLatina; con un enfoque histórico-lógico y de análisis-síntesis. Conclusiones: El diagnóstico precoz de la tuberculosis intestinal sin tuberculosis pulmonar activa continúa siendo un problema de salud, ya que los parámetros clínicos, bioquímicos, imagenológicos y endoscópicos aún carecen de especificidad, y en algunos casos se ha mostrado resistencia al tratamiento habitual(AU)
Introduction: Tuberculosis is a reemerging disease, also important as a major cause of disability and death in many regions of the world. Abdominal tuberculosis represents 11 percent of all extrapulmonary forms; 0.5 percent of all new cases of HIV infection and 10-15 percent of those not infected with HIV. In Las Tunas Municipality, the case of a 17-year-old male adolescent who was diagnosed with this disease was reported after the patient presented symptoms of recurrent abdominal pain for several months before diagnosis. Objective: To update information on the diagnosis and treatment of abdominal tuberculosis. Methods: A literature review on intestinal tuberculosis was carried out with the literature found in databases available on the Infomed network, such as PubMed, Hinari, The Cochrane Library, SciELO, MEDLINE, and MedicLatina, with a historical-logical and analysis-synthesis approach. Conclusions: The early diagnosis of intestinal tuberculosis without active pulmonary tuberculosis continues to be a health concern, since clinical, biochemical, imaging, and endoscopic parameters still lack specificity, and, in some cases, resistance to usual treatment has been shown(AU)

OBJECTIVE: To study the clinicopatholgical profile and outcomes of surgical management of abdominal tuberculosis (ATB) Study Design: Cross-sectional observational study. PLACE AND DURATION OF STUDY: Department of Surgery, Services Hospital, Lahore, Pakistan, from May 2008 to April 2018. METHODOLOGY: All patients who underwent emergency laparotomy during the study period due to abdominal tuberculosis, and consented to participate in the study were included. Demographic variables and type of surgical procedure performed were recorded. Patients were followed-up for histopathology, recurrence, or any anti-tuberculous therapy related complications at 1, 4, 6, and 12 months. Data were analysed using SPSS version 21. RESULTS: Out of the 80 patients, 36 were males and 44 were females. The median age was 23.5 years (range = 11-90 years). Mean weight of the patients was 48.7 ±12.2 kg. Commonest presenting symptom was abdominal pain 72 (90%). On exploration, ileocecal region was most commonly involved segment 68 (85%). Stoma formation was the most common surgical procedure performed in 59 (73.8%) patients. Complications and mortality rate were 48 (60%) and 7 (8.7%), respectively. A significant relationship of complications was found with prolonged hospital stay (p <0.001). CONCLUSION: Abdominal tuberculosis is a major public health concern. Vague symptoms lead to diagnostic delay so patients present late with intestinal obstruction. Ileocecal tuberculosis is the most common site of involvement.

BACKGROUND: Few data are published on perianal tuberculosis. OBJECTIVE: This study aimed to determine the best method to diagnose tuberculosis in patients with fistula-in-ano and to conduct a systematic review to determine the incidence and characteristics of tuberculosis fistula-in-ano. DATA SOURCES: The prospective study data and existing literature were derived from PubMed, Google scholar, and Scopus STUDY SELECTION:: Prospective analysis of patients with tuberculous fistula-in-ano treated between 2014 and 2018 was conducted, and a systematic review of studies describing ≥3 patients with tuberculosis fistula-in-ano was completed. INTERVENTION: Testing of tuberculosis was performed by histopathology or polymerase chain reaction of tissue or pus from the fistula tract. MAIN OUTCOME MEASURES: The primary outcomes measured were the detection rate of various tests to detect tuberculosis in fistula-in-ano and the prevalence rate of tuberculosis in simple versus complex fistulas. RESULTS: In 637 samples (410 patients) tested, tuberculosis was detected in 49 samples (43 patients). Additional samples (n = 106) sent in patients with a high index of suspicion tested positive in 14 more patients. Thus, overall, 63 samples tested positive in 57 patients (total: 743 samples in 410 patients were tested). Tuberculosis was detected in 2 of 181 patients (1.1%) in tissue (histopathology), in 28 of 341 patients (8.2%) in tissue (polymerase chain reaction), and in 19 of 115 patients (16.5%) in pus (polymerase chain reaction) samples. To detect tuberculosis, tissue (polymerase chain reaction) was significantly better than tissue (histopathology) (28/341 vs 2/181, p < 0.00001) and pus (polymerase chain reaction) was significantly better than tissue (polymerase chain reaction) (19/115 vs 28/341, p < 0.0009). Tuberculosis was significantly more common in complex fistulas than in simple fistulas (20.3% vs 7.2%, p = 0.0002). The systematic review (n = 199) highlighted that tubercular fistulas are more common in recurrent and complex fistulas and in tuberculosis endemic regions. LIMITATIONS: The true sensitivity and specificity of each testing modality could not be determined because not all patients with tuberculosis fistula-in-ano were tested by every diagnostic modality studied. CONCLUSIONS: The tuberculosis detection rate of polymerase chain reaction was significantly higher than histopathology. Among polymerase chain reaction, pus had higher detection rate than tissue. Tuberculosis was associated with more complex and recurrent fistulas.

Mycobacterium bovis is responsible for bovine tuberculosis in both animals and humans. Despite being one of the most important global zoonotic disease, data related to the ecology and pathogenicity of bovine tuberculosis is scarce, especially in developing countries. In this report, we examined the dynamics of M. bovis transmission among dairy cattle in the Nile Delta of Egypt. Animals belonging to 27 herds from 7 governorates were tested by the Single Intradermal Comparative Skin Tuberculin (SICST), as a preliminary screen for the presence of bovine tuberculosis. Positive SICST reactors were identified in 3% of the animals spread among 40% of the examined herds. Post-mortem examination of slaughtered reactors confirmed the presence of both pulmonary and/or digestive forms of tuberculosis in > 50% of the examined animals. Targeted and whole-genome analysis of M. bovis isolates indicated the emergences of a predominant spoligotype (SB0268) between 2013-2015, suggesting a recent clonal spread of this isolate within the Nile Delta. Surprisingly, 2 isolates belonged to M. bovis BCG group, which are not allowed for animal vaccination in Egypt, while the rest of isolates belonged to the virulent M. bovis clonal complex European 2 present in Latin America and several European countries. Analysis of strain virulence in the murine model of tuberculosis indicated the emergence of a more virulent strain (MBE4) with a specific genotype. More analysis is needed to understand the molecular basis for successful spread of virulent isolates of bovine tuberculosis among animals and to establish genotype/phenotype association.

BACKGROUND: Abdominal tuberculosis (TB) is an uncommon form of infection with Mycobacterium tuberculosis in Korea. In this study, we aimed to highlight the clinical features, diagnostic methods, and outcomes of abdominal TB over 12 years in Southeastern Korea. METHODS: A total of 139 patients diagnosed as having abdominal TB who received anti-TB medication from January 2005 to June 2016 were reviewed. Among them, 69 patients (49.6%) had luminal TB, 28 (20.1%) had peritoneal TB, 7 (5.0%) had nodal TB, 23 (16.5%) had visceral TB, and 12 (8.6%) had mixed TB. RESULTS: The most frequent symptoms were abdominal pain (34.5%) and abdominal distension (21.0%). Diagnosis of abdominal TB was confirmed using microbiologic and/or histologic methods in 76 patients (confirmed diagnosis), while the remaining 63 patients were diagnosed based on clinical presentation and radiologic imaging (clinical diagnosis). According to diagnostic method, frequency of clinical diagnosis was highest in patients with luminal (50.7%) or peritoneal (64.3%) TB, while frequency of microscopic diagnosis was highest in patients with visceral TB (68.2%), and frequency of histologic diagnosis was highest in patients with nodal TB (85.2%). Interestingly, most patients, except those with nodal TB, showed a good response to anti-TB agents, with 84.2% showing a complete response. The mortality rate was only 1.4% in the present study. CONCLUSIONS: Most patients responded very well to anti-TB therapy, and surgery was required in only a minority of cases of suspected abdominal TB.

OBJECTIVE: To describe the experience with abdominal tuberculosis (TB), including potential risk factors, presentation, diagnosis, treatment and clinical course, at one Canadian clinic. DESIGN: This was a retrospective case series of all patients with abdominal TB (excluding the genito-urinary system and abdominal muscle) who received care at the Saint Michael's Hospital TB Clinic (Toronto, ON, Canada) from April 2003 to July 2016. RESULTS: Of 590 active TB cases encountered between April 2003 and July 2016, 24 (4.1%) had abdominal TB. All cases were foreign-born, and over 50% occurred among individuals who were not recent immigrants. Background abdominal illnesses and immunocompromised health status were rarely seen. Lymphadenitis (58.3%) and the peritoneum (41.7%) were the most common forms of abdominal TB, bowel involvement was infrequent and most had concomitant extra-abdominal disease (62.5%). All cases were cured, largely using ⩾9 months of pharmacotherapy. Gastrointestinal intolerance and liver dysfunction were rarely observed side effects of therapy. CONCLUSIONS: Several traditional TB risk factors occurred infrequently among our cases, which highlights the importance of having a low threshold for considering abdominal TB in the appropriate clinical setting. Although abdominal TB often occurred in the context of disseminated disease, cure was achievable, but ⩾9 months of treatment may generally be needed.

BACKGROUND: Overlapping clinical, endoscopic, radiographic and histological features, coupled with poor microbiological yield, make differentiating Crohn's disease (CD) from intestinal tuberculosis (ITB) challenging. Granulomas are present in both diseases; in CD they predict the need for immunosuppressive therapy that requires ITB to be excluded before initiation. OBJECTIVES: To compare granuloma-positive CD and ITB, to identify factors that may aid in diagnosis. METHODS: This was a retrospective cohort study evaluating granuloma-positive CD and ITB identified from a pathology database. RESULTS: Sixty-eight ITB and 48 CD cases were identified. Patients with ITB were more likely to be male, and to have HIV infection, isolated colitis, night sweats and tachycardia. ITB was also associated with lower serum albumin and haemoglobin and higher C-reactive protein levels, a chest radiograph showing active tuberculosis, and lymph nodes >1 cm on imaging. Extraintestinal manifestations (EIMs) were predictive of CD. There were no significant differences in smoking status, symptom duration or perianal disease. On multivariate analysis, HIV positivity (odds ratio (OR) 29.72, 95% confidence interval (CI) 2.15 - 410.96; p=0.01), isolated colitis (OR 6.17, 95% CI 1.17 - 32.52; p=0.03) and the absence of EIMs (OR 0.10, 95% CI 0.01 - 0.65; p=0.02) remained significant risk factors for ITB. CONCLUSION: This is the first study to identify clinical and biochemical factors to aid in differentiating granuloma-positive ITB from CD. EIMs support a diagnosis of CD, while isolated colitis and HIV are predictors of ITB.

BACKGROUND: Globalization and emigration impact on the spectrum of diseases challenging health care systems. Medical practitioners have to particularly prepare for infectious diseases. METHODS: The database of a health care center specialized on tropical medicine was screened for patients with history of migration and one of the following diagnoses: Cystic echinococcosis, tuberculosis, schistosomiasis, visceral leishmaniosis, and neurocysticercosis. Representative casuistics were prepared from select case histories. Radiological pertinent knowledge was compiled based on literature search. RESULTS: A small selection of frequently imported infectious diseases covers a considerable fraction of health care problems associated with migration. For cystic echinococcosis, schistosomiasis, and neurocysticercosis imaging is the most relevant diagnostic procedure defining also disease stages. Tuberculosis and visceral leishmaniosis are important differentials for malignant diseases. CONCLUSION: Imaging plays a meaningful role in diagnosis, treatment stratification, and follow-up of imported infectious diseases. Radiological skills concerning these diseases are important for providing health care for patients in context of migration. KEY POINTS: · Imaging plays a meaningful role in multidisciplinary care for imported infectious diseases.. · A small selection covers a considerable fraction of infectious diseases expected in context of migration..

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.

BACKGROUND/AIMS: In some Western countries, up to 50% of patients with ankylosing spondylitis (AS) have subclinical gut inflammation. This study was conducted to evaluate the prevalence and severity of gut inflammation and to determine clinical factors associated with colonic inflammation in Korean AS patients who performed ileocolonoscopy without evidence of established inf lammatory bowel diseases before. METHODS: One hundred and eight AS patients who underwent ileocolonoscopy were included in this study. Patients were divided into two groups based on gross ileocolonoscopic findings; patients with inflammatory lesions, and patients without inflammatory lesions. RESULTS: Inf lammatory lesions in ileocolonoscopic findings were found in 40 patients. The Ankylosing Spondylitis Disease Activity Score C-reactive protein was higher in the group with inflammatory lesions and gut lesions were found often in the terminal ileum. The risk of inflammatory lesions was higher for AS patients whose symptoms required ileocolonoscopy than for AS patients who underwent routine ileocolonoscopy screening (odds ratio, 3.96). However, abnormal lesions were detected also in 17.6% of the patients who underwent ileocolonoscopy for routine screening and most of them were erosion and ulcer. Among patients with inflammatory lesions (n = 40), 23 showed subclinical gut inflammation associated with AS and 17 were diagnosed finally as Crohn's disease (n = 12), intestinal tuberculosis (n = 4), and ulcerative colitis (n = 1). CONCLUSIONS: Our findings suggest that ileocolonoscopy might be recommended regularly in AS patients even without gastrointestinal symptoms, especially in the patients with high AS activity.
