RESUMO
BACKGROUND & AIMS: Coconut water (CW) is anti-inflammatory, can manipulate the gut microbiome, and is a rich source of potassium. Gut microbiome modulation improves outcomes in ulcerative colitis (UC), and potassium possesses in vitro anti-inflammatory property. We evaluated the effect of CW as an adjunct therapy for patients with mild-moderate UC. METHODS: This single-center, double-blind, placebo-controlled trial randomized patients with mild to moderate (Simple Clinical Colitis Activity Index [SCCAI]: 3-9) endoscopically active UC (Ulcerative Colitis Endoscopic Index of Severity [UCEIS] >1) in 1:1 ratio to CW + standard medical therapy (SMT) vs placebo + SMT. Four hundred mL of CW was administered for 8 weeks. Primary outcome measure was clinical remission (SCCAI ≤2), and secondary outcome measures were clinical response (SCCAI decline ≥3) and adverse events at 8 weeks. Microbiome was analyzed at baseline and 8 weeks. RESULTS: Of 121 patients screened, 95 were included for modified intention to treat analysis (CW, n = 49; placebo, n = 46) (mean age, 37.2 ± 11.2 years; males, 54.1%; disease duration, 48 months [interquartile range (IQR), 24-90 months]; pancolitis, 26.1%; SCCAI, 5 [IQR, 4-6]; UCEIS, 4 [IQR, 3-5]). Clinical response (57.1% vs 28.3%; odds ratio [OR], 3.4; 95% confidence interval [CI], 1.4-7.9; P = .01), remission (53.1% vs 28.3%; OR, 2.9; 95% CI, 1.2-6.7; P = .02), and proportion of patients with fecal calprotectin (FCP) <150 µg/g (30.6% vs 6.5%; OR, 6.3; 95% CI, 1.7-23.6; P = .003) were significantly higher in CW. The relative abundance of bacterial taxa that had a significant or trend towards negative correlation with SCCAI, UCEIS, or FCP increased at 8 weeks in CW, and this effect was independent of disease activity and dietary fiber. Adverse events were comparable, and no patient developed hyperkalemia. CONCLUSIONS: CW was more effective than placebo for induction of clinical remission in patients with mild to moderate UC. The trial was prospectively registered on Clinical Trials Registry of India (ctri.nic.in, Number: CTRI/2019/03/01827).

BACKGROUND: Targeting interleukin-23 (IL-23) is an important therapeutic strategy for Crohn's disease (CD). AIMS: This systematic review and meta-analysis assessed the efficacy and safety of selective IL-23p19 and IL-12/23p40 inhibitors in patients with moderate-to-severe CD. METHODS: MEDLINE, Embase, and the Cochrane library (CENTRAL) were searched from inception to May 24, 2023, for randomized, placebo- or active comparator-controlled induction and/or maintenance trials of selective IL-23p19 and IL-12/23p40 inhibitors in pediatric and adult patients with CD. The primary outcome was the proportion of patients in clinical remission. Secondary outcomes were clinical response, endoscopic remission, endoscopic response, and safety. Data were pooled using a random-effects model. Risk of bias and certainty of evidence were assessed using the Cochrane risk of bias tool and the GRADE criteria, respectively. RESULTS: Eighteen trials (n = 5561) were included. Most studies were rated as low risk of bias. Targeting IL-23 was significantly superior to placebo for inducing clinical (risk ratio [RR] = 1.87, 95% confidence interval [CI] 1.58-2.21) and endoscopic (RR = 3.20, 95%CI 2.17-4.70) remission and maintaining clinical remission (RR = 1.39, 95%CI 1.10-1.77) (GRADE high certainty evidence for all outcomes). Subgroup analysis showed that targeting IL-23 was superior to placebo for inducing clinical remission in biologic-naïve (RR = 2.20, 95%CI 1.46-3.32, I2 = 0%, p = 0.39) and biologic-experienced patients (RR = 1.82, 95%CI 1.27-2.60, I2 = 56.5%, p = 0.01). Targeting IL-23 was associated with a decreased risk of serious adverse events in induction (RR = 0.55, 95%CI 0.44-0.73) and maintenance (RR = 0.72, 95%CI 0.53-0.98) trials compared to placebo (high certainty evidence). CONCLUSION: Targeting IL-23 is effective and safe for inducing and maintaining clinical and endoscopic remission in patients with moderate-to-severe CD.

The novel coronavirus SARS-CoV-2 is responsible for the devastating pandemic which has caused more than 5 million deaths across the world until today. Apart from causing acute respiratory illness and multiorgan dysfunction, there can be long-term multiorgan sequalae after recovery, which is termed 'long COVID-19' or 'post-acute COVID-19 syndrome'. Little is known about long-term gastrointestinal (GI) consequences, occurrence of post-infection functional gastrointestinal disorders and impact the virus may have on overall intestinal health. In this review, we put forth the various mechanisms which may lead to this entity and possible ways to diagnose and manage this disorder. Hence, making physicians aware of this spectrum of disease is of utmost importance in the present pandemic and this review will help clinicians understand and suspect the occurrence of functional GI disease post recovery from COVID-19 and manage it accordingly, avoiding unnecessary misconceptions and delay in treatment.

PURPOSE: Withdrawal of thiopurines after remission is associated with an increased risk of relapse in patients with inflammatory bowel disease (IBD). However, long-term data on thiopurine withdrawal is limited, especially from developing countries where the cost of long-term therapy poses a significant burden on patients. METHODS: Patients with IBD on thiopurine monotherapy for ≥ 4 months, who stopped thiopurines while in clinical remission and were not on any other immunomodulator or biologics at the time of withdrawal, were included in this retrospective analysis. RESULTS: Among 1093 patients with IBD on thiopurine monotherapy, 461 patients stopped thiopurine due to various reasons. Among these, 218 (ulcerative colitis (UC) = 179; Crohn's disease (CD) = 39) patients were in clinical remission and were continued on mesalamine. Overall, 36.7% (n = 80) relapsed after a median duration of 20 months (IQR: 9-49). Relapse rate was higher in UC than CD (39.7% vs 23%, p = 0.055). Cumulative probabilities of relapse were 17%, 34%, and 44% at the end of 1, 3, and 5 years, respectively. The relapse rate at 5 years was significantly lower in patients who had stopped azathioprine after 4 years of therapy (31% vs 54%, p = 0.007). On multi-variate cox regression analysis, male sex [HR: 1.6(1.0-2.6), p = 0.02] and short duration of therapy with thiopurines [HR: 1.02 (1.01-1.02), p = 0.004] before withdrawal were associated with increased risk of relapse. CONCLUSION: Approximately 50% patients with IBD in remission would relapse after 5 years of thiopurine withdrawal. Male sex and shorter treatment duration predict relapse. Treatment should be continued in patients who tolerate and maintain remission on long-term thiopurine.

BACKGROUND AND AIM: Thiopurines are widely used to maintain remission in both ulcerative colitis (UC) and Crohn's disease (CD). Reported effectiveness and tolerability rates have been variable across studies. There are only sparse data in Asian population regarding the long-term efficacy and safety of thiopurines. METHODS: Records of 5351 patients followed up at inflammatory bowel disease (IBD) clinic, All India Institute of Medical Sciences, New Delhi from 2004 to 2020 were evaluated retrospectively. Safety was evaluated in terms of long-term adverse events and development of malignancy. RESULTS: Of 5351 patients with IBD, 1093 who received thiopurine for > 3 months (UC = 788 [proctitis-1.9%, left-sided colitis-44.9%, & pancolitis-53.1%] & CD = 305 [inflammatory-42.6%, stricturing-46.9%, & fistulizing-10.5%]) were included (60.8%-male patients). Follow up and treatment duration on thiopurine were 7 (4-12) years and 39.4 ± 40.3 months, respectively, with 254 (23.2%) patients receiving thiopurines for more than 5 and 68 (6.2%) receiving for more than 10 years. Three hundred and fifty-nine (UC: 249 [31.6%]; CD: 110 [36.1%]; P = 0.1) patients developed adverse events; commonest was myelosuppression (23.4%) followed by gastrointestinal intolerance (3%), flu-like illness (1.7%), and arthralgia/myalgia (1.4%). Myelosuppression was the commonest cause of thiopurine withdrawal. No patient (including 254 patients on thiopurine for ≥ 5 years) developed lymphoma or non-melanoma skin cancer. The cumulative probability of staying free from adverse events in overall IBD cohort at 1, 2, and 5 years was 78.6%, 71.9%, and 68.4%, respectively, and this was comparable between UC and CD (P = 0.09). CONCLUSION: Long-term follow up of patients with IBD from northern India on thiopurine monotherapy demonstrated minimal risk of development of lymphoma as well as non-melanoma skin cancer.

BACKGROUND AND AIM: There is a paucity of data on the clinical presentations and outcome of Budd-Chiari syndrome (BCS) patients presenting as acute-on-chronic liver failure (BCS-ACLF). We aimed to describe the profile and outcomes of endovascular interventions in patients with BCS-ACLF. METHODS: All BCS-ACLF patients presenting between October 2007 and April 2019 satisfying the Asian Pacific Association for the Study of the Liver (APASL) definition were studied. We compared 30- , 90- and, 180-day survival among BCS-ACLF patients who underwent endovascular intervention with those who did not, and with a historical cohort of Child-C BCS patients without ACLF who underwent endovascular intervention. RESULTS: Twenty-eight (5%) of 553 BCS patients presented as ACLF as per APASL definition. The majority (60.7%) were males, and mean age was 29.6 ± 11.2 years. The most common site of the block was isolated involvement of hepatic veins-HV (68%), followed by combined inferior vena cava (IVC) and HV block (25%) and isolated IVC block (7%). The acute precipitants were stent thrombosis (17.9%), acute HV thrombosis (10.7%), acute viral hepatitis (7.1%), and antituberculosis drug with hepatitis B virus reactivation (3.6%). In 60.7% patients, no acute precipitant could be identified. The 30- , 90- , and 180-day survival in BCS-ACLF post-endovascular intervention (n = 15), BCS-ACLF without endovascular intervention (n = 13), and Child-C BCS without ACLF who underwent endovascular intervention (n = 25) were (93%, 87%, and 87%), (46%, 28%, and 0%) and (96%, 92%, and 88%), respectively (log-rank test, p value < 0.001). On multivariate Cox proportional analysis, endovascular intervention and the presence of hepatic encephalopathy were independent predictors of mortality. CONCLUSION: Budd-Chiari syndrome can present as acute-on-chronic liver failure. Endovascular intervention is associated with an improved outcome.

Acute Severe Ulcerative Colitis (ASUC) is a severe form of ulcerative colitis relapse which requires hospitalization and intensive medical intervention to avoid colectomy. The timely recognition of patients at risk of corticosteroid failure and the early initiation of medical rescue therapy are paramount in the management of ASUC. The choice of medical rescue therapy is influenced by multiple factors, especially patient's prior treatment history. This decision should involve the patient and ideally a multidisciplinary team of healthcare professionals, including gastroenterologists, radiologists, surgeons and enterostomal therapists. Although several predictive models have been developed to predict corticosteroid failure in ASUC, there is no single validated tool that is universally utilized. At present, infliximab and cyclosporine are the only agents systematically evaluated and recommended for medical rescue therapy, with recent reports of off-label utilization of tofacitinib and upadacitinib in small case series. The available evidence regarding the efficacy and safety of these oral small molecules for ASUC is insufficient to provide definitive recommendations. Early decision-making to assess the response to medical rescue therapy is essential, and the decision to pursue surgery in the case of treatment failure should not be delayed.
RESUMO
BACKGROUND: Stricturing, penetrating complications and extraintestinal manifestations (EIMs) are frequent in patients with inflammatory bowel disease (IBD). There is limited data on the prevalence of these complications in patients with IBD. Therefore, we aimed to assess the burden of these complications detected incidentally on cross-sectional imaging. METHODS: A retrospective study conducted at two tertiary care centers in London, Ontario. Patients (≥18 years) with a confirmed diagnosis of IBD who underwent CT enterography (CTE) or MR enterography (MRE) between 1 Jan 2010 and 31 Dec 2018 were included. Categorical variables were reported as proportions and the mean and standard deviations were reported for continuous variables. RESULTS: A total of 615 imaging tests (MRE: 67.3% [414/615]) were performed in 557 IBD patients (CD: 91.4% [509/557], UC: 8.6% [48/557]). 38.2% (213/557) of patients were male, with mean age of 45.6 years (±15.8), and median disease duration of 11.0 years (±12.5). Among patients with CD, 33.2% (169/509) had strictures, with 7.8% having two or more strictures and 66.3% considered inflammatory. A fistula was reported in 10.6% (54/509), the most common being perianal fistula (27.8% [15/54]), followed by enterocutaneous fistula (16.8% [9/54]), and enteroenteric fistula (16.8% [9/54]). Additionally, 7.4% (41/557) of patients with IBD were found to have an EIM on cross-sectional imaging, with the most prevalent EIM being cholelithiasis (63.4% [26/41]), followed by sacroiliitis (24.4% [10/41]), primary sclerosing cholangitis (4.8% [2/41]) and nephrolithiasis (4.8% [2/41]). CONCLUSIONS: Approximately 40% of patients with CD undergoing cross-sectional imaging had evidence of a stricture or fistulizing disease, with 7% of patients with IBD having a detectable EIM. These results highlight the burden of disease and the need for specific therapies for these disease phenotypes.
RESUMO
BACKGROUND AND AIMS: Thiopurines are viable option for the treatment of inflammatory bowel disease [IBD] in resource-limited countries. However, data on the effect of disease duration at thiopurines initiation on long-term effectiveness are limited. METHOD: We performed a propensity matched analysis of a retrospective cohort of patients with ulcerative colitis [UC] and Crohn's disease [CD]. Patients initiated on thiopurines early in the disease course [≤2 years] were compared with those started late [>2 years]. Effectiveness was defined as no requirement for hospitalisation, anti-tumour necrosis factor [TNF] agents, or surgery, and minimum steroid requirement [≤1 steroid course in 2 years] during follow-up. RESULTS: A total of 988 [UC: 720, CD: 268] patients were included (male: 665 [60.8%], median age: 40 [32-51] years, median follow-up: 40 [19-81] months). Overall effectiveness at 5 and 10 years was 79% and 72% in UC, and 69% and 63% in CD, respectively. After propensity score matching, there was no difference in 5- and 10-year effectiveness between early and late thiopurine initiation groups either for UC [81% and 80% vs 82% and 74%; pâ =â 0.92] or CD [76% and 66% vs 72% and 51%, pâ =â 0.32]. Male sex for UC (negative: hazard ratio [HR]: 0.67, 95% confidence interval [CI): 0.45-0.97; pâ =â 0.03), and ileal involvement [positive: HR: 3.03, 95% CI: 1.32-6.71; pâ =â 0.008], steroid-dependent disease [positive: HR: 2.70, 95% CI: 1.26-5.68; pâ =â 0.01] and adverse events [negative: HR: 0.47, 95% CI:0.27-0.80; pâ =â 0.005] for CD were predictors of thiopurine effectiveness. CONCLUSION: Thiopurines have sustained long-term effectiveness in both UC and CD. However, early thiopurine initiation had no better effect on long-term disease outcome compared with late initiation.

BACKGROUND: Perianal fistulas (PF) affect one-third patients with Crohn's disease (CD) with limited therapeutic options. There is dearth of literature on safety and efficacy of bone marrow-derived mesenchymal stromal cells (BMSCs) in this population. METHODS: An open-label, phase I/II, single-arm study was conducted involving local administration of human allogeneic bone marrow-derived mesenchymal stromal cells in perianal fistula of patients with Crohn's disease refractory to standard therapies. Clinical severity and biomarkers were assessed at baseline and periodically until week 104 , and MRI at week 24 and 104. Primary and secondary objectives were to assess safety and efficacy respectively. Fistula remission was complete closure of fistula openings with < 2 cm perianal collection on MRI, and fistula response was decrease in drainage by ≥ 50%. Change in perianal disease activity index, quality-of-life and Van Assche index on MRI over time was assessed using mixed-effect linear regression model. RESULTS: Ten patients (male:8, mean age:27.4 ± 12.0years) were recruited. Self-resolving procedure-related adverse events occurred in three patients, with no follow-up adverse events. In intention to treat analysis at week 24, two patients (20%) achieved fistula remission and seven (70%) had fistula response. At week 52, two (20%) patients were in remission and seven (70%) maintained response. At 104 weeks, two (20%) patients maintained response and one (10%) was in remission. Statistically significant decrease in perianal disease activity index (P = 0.008), Van Assche Index (P = 0.008) and improvement in quality-of-life (P = 0.001) were observed over time. CONCLUSIONS: Allogeneic BMSCs are safe and effective for the treatment of perianal fistulizing CD with significant improvement in clinical severity and radiological healing. TRIAL REGISTRATION: The study was prospectively registered on Clinical trials registry - India (CTRI), CTRI/2020/01/022743 on 14 January 2020, http://ctri.nic.in .

BACKGROUND: Crohn's disease (CD) is characterized by discontinuous inflammation. Failure to identify skipping lesions of the terminal ileum (TI) or transmural changes can lead to incorrect management. METHODS: Eligible adult patients with CD undergoing ileo-colonoscopy and computed tomography enterography or magnetic resonance enterography within 6 months. We determined the prevalence of endoscopic skipping (normal ileum on colonoscopy but proximal small bowel inflammation on cross-sectional imaging), skip lesions (discontinuous inflammation along the gastrointestinal tract identified on cross-sectional imaging), structuring, and penetrating complications. RESULTS: Among 202 patients, 45 (22.3%) had endoscopic skipping proximal to TI intubation. Fifty patients (24.5%) had small bowel skip lesions, primarily in the ileum. Strictures were identified in 34 patients (16.8%) through both imaging and ileo-colonoscopy, in 21 patients (10.4%) solely through cross-sectional imaging, and in 3 patients (1.5%) solely through ileo-colonoscopy. Approximately 36.2% of stricturing cases would be missed without cross-sectional imaging. Penetrating complications, including abscesses (2.5%) and various fistula types (4.9%), were detected in 15 (7.4%) patients. CONCLUSIONS: Ileo-colonoscopy missed detection of active CD in approximately one-fifth of cases due to more proximal disease location. Stricturing disease might be missed in more than a third of cases if cross-sectional imaging is not performed.
Crohn's disease often presents with discontinuous inflammation, with endoscopic evaluation sometimes missing proximal lesions. This study highlights the importance of cross-sectional imaging, which identifies skip lesions and strictures missed by endoscopy, crucial for accurate management.
RESUMO
BACKGROUND: The information on seroprevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among patients with inflammatory bowel disease (IBD) and its comparison to healthy controls is sparse. We compared the seroprevalence rates in patients with IBD and healthy controls (HCs). METHODS: Patients with IBD and HCs (contact of patients) underwent SARS-CoV-2 antibody testing (chemiluminescent immunoassay: Siemens kit IgG against antigen-S1RBD) between July 2020 and April 2021. Information on demography, disease characteristics, drug history and past history of SARS-CoV-2 infection were noted. Patients on 5-aminosalicylic acid or no treatment were considered not on immunosuppressants and those who had received steroids, thiopurines or methotrexate within six months of inclusion were considered being on immunosuppressants. RESULTS: A total of 235 patients (51.9%, males; mean age, 38.7 ± 12.4 years; median disease duration, 60 months [interquartile range, IQR: 36-120]) (ulcerative colitis [UC]: 69.4%, Crohn's disease [CD]: 28.9%, IBD unclassified [IBDU]: 1.7%) and 73 HCs (mean age, 39.6 ± 10.9 years, 80% males) were enrolled. Of the 235 patients, 128 (54.5%) patients were on immunosuppressants and 107 (45.5%) were not on immunosuppressants. Seventy-four (31.5%) patients were seropositive, of which two (0.9%) had previous history of SARS-CoV-2 infection and none received coronavirus disease-19 (COVID-19) vaccine. Seroprevalence between IBD patients and HCs (32% vs. 27%, p > 0.05) and between patients with and without immunosuppressants (28.1% vs. 36%, p > 0.05) was similar. Age, gender, disease type, duration and activity in the last six months; and medication use were similar between patients with positive and negative serology. There was a progressive increase in seroprevalence from July 2020 to April 2021. CONCLUSION: Up to 1/3rd of patients with IBD were seropositive for immunoglobulin G (IgG) SARS-Cov-2 antibody indicating high seroprevalence in patients with IBD from Northern India.

BACKGROUND/AIMS: Intestinal tuberculosis (ITB) is difficult to diagnose due to poor sensitivity of definitive diagnostic tests. ITB may be associated with concomitant pulmonary tuberculosis (PTB) which may remain undetected on chest X-ray. We assessed the role of contrast enhanced computed tomography (CECT) chest in detecting the prevalence of active PTB, and increasing the diagnostic yield in patients with suspected ITB. METHODS: Consecutive treatment naïve patients with suspected ITB (n=200) who underwent CECT chest (n=88) and had follow-up duration>1 year were recruited in this retrospective study (February 2016 to October 2018). ITB was diagnosed in the presence of caseating granuloma, positive acid fast stain or culture for Mycobacterium tuberculosis on biopsy, presence of necrotic lymph nodes (LNs) on CT enterography or positive response to anti-tubercular therapy. Evidence of active tuberculosis on CECT-chest was defined as presence of centrilobular nodules with or without consolidation/miliary nodules/thick-walled cavity/enlarged necrotic mediastinal LNs. RESULTS: Sixty-five of eighty-eight patients (mean age, 33.8±12.8 years; 47.7% of females) were finally diagnosed as ITB (4-caseating granuloma on biopsy, 12-necrotic LNs on CT enterography, 1-both, and 48-response to anti-tubercular therapy) and 23 were diagnosed as Crohn's disease. Findings of active TB on CECT chest with or without necrotic abdominal LNs were demonstrated in 5 and 20 patients, respectively. No patient with Crohn's disease had necrotic abdominal LNs or active PTB. Addition of CECT chest in the diagnostic algorithm improved the sensitivity of ITB diagnosis from 26.2% to 56.9%. CONCLUSIONS: Addition of CECT chest significantly improves the sensitivity for definite diagnosis in a patient with suspected ITB.
RESUMO
BACKGROUND: Stricturing Crohn's disease (CD) is difficult to manage medically with limited treatment options, anti-tumor necrosis factor (TNF) therapy being the first-line therapy. Although thiopurines are also recommended first-line treatment option for maintenance of remission in steroid-dependent CD, evidence on their use in stricturing CD is lacking. We evaluated the efficacy of azathioprine (AZA) in patients with stricturing CD. METHODS: In this retrospective cohort study (January 2005 to July 2020), patients with stricturing CD who were managed with AZA as a primary therapy for at least 6 months, and had a follow-up of at least 6 months after AZA initiation were included. Disease characteristics, complications, long-term response, and adverse events were noted. RESULTS: One hundred and fifteen patients were included (mean age 33.8±14 years, 67.8% males, median disease duration 98 months [IQR: 60-158], median follow-up duration 60 months [IQR: 50-96]). 46.1% (n=53) patients had significant anemia at presentation, and 73% (n=84) had isolated small bowel involvement. Median dose of AZA was 100 mg (equivalent to 1.5 mg/kg). Median therapy and follow-up duration (after AZA initiation) was 17 (IQR: 9-42) and 33 months (IQR 18-60), respectively. The cumulative probability of maintaining response without treatment failure at 1, 2, and 5 years was 73.1%, 40.7%, and 18.5%, respectively. Among patients with AZA failure, 15.6% received methotrexate, 13% received anti-TNFs, and 9.5% underwent surgery. Significant anemia (<10 g/dL) at presentation and steroid dependence predicted AZA failure. 31.3% patients experienced adverse events, commonest being leukopenia (n=29, 25.2%). CONCLUSION: Azathioprine demonstrated good short-term and modest long-term response rates in patients with stricturing CD.

BACKGROUND: The information on the risk of thromboembolism (TE) in inflammatory bowel disease (IBD) and its predictors are lacking, especially from developing countries. The present study evaluated the prevalence, predictors, and prognosis of TE in IBD. METHODS: This case-control study included 35 patients with IBD (ulcerative colitis [UC, n = 25]; Crohn's disease [CD], n = 10) and history of TE, from a cohort of 3597 patients (UC n = 2752, CD n = 845) under follow-up from 2005 to 2018. Details on demographics, extraintestinal manifestations (EIMs), patient status, type and outcomes of TE, treatment details, and disease course were compared with IBD patients without TE (age, gender, and duration of follow-up matched) in the ratio of 1:4. RESULTS: Prevalence of TE in IBD was 0.9% (UC-0.89%, CD-1.2%). Among TE patients (mean age: 34.9 ± 13.1 years, 48.6% males), median duration from diagnosis to TE was 12 (inter-quartile range [IQR]: 3-36) months, 37% had other EIMs, 94.1% had moderate/severe disease at time of TE, 62.8% had steroid-dependent/refractory disease, and 5 patients (14.2%) died because of disease-related complications. Lower limb was the commonest site (57.1%), 14.3% had pulmonary TE, and 31.4% had involvement of multiple sites. Phenotypically, more patients with TE (among UC) had steroid-dependent disease (60% vs. 25%, p = 0.001), pancolitis (76% vs. 36%, p = 0.002), chronic continuous disease course (44% vs. 19%, p = 0.009), and acute severe colitis (48% vs. 18%, p = 0.002), of which the latter three were also independent predictors of TE. CONCLUSION: Approximately 1% of patients with IBD develop thromboembolism relatively early during their disease course, and TE is associated with severe disease and higher disease-related complications including mortality.

The use of smartphone-based applications as a telenutrition tool could redefine the nutritional management of IBD. We developed and validated a digital health platform in the form of a smartphone application for the nutritional assessment of IBD patients. Our team of gastroenterologists and dieticians at the All-India Institute of Medical Sciences, New Delhi developed a smartphone application titled IBD NutriCare, which was made available in both Android and iOS interfaces in English and seven other Indian languages. The application includes >650 Indian recipes and provides subjective global assessment and IBD clinical activity scores in a patient-friendly manner. The utility of the smartphone app was validated in comparison with the traditional 24-h dietary recall method. A total of 49 IBD patients were enrolled in the study. The mean difference in energy intake between the two dietary assessment methods was −4.776 kJ (95% LOA, range −417.916−408.365 kJ). A total of 94% of patients found the smartphone application convenient and acceptable in comparison to the recall method for dietary assessment. Bland−Altman plots showed a good level of agreement for nutrients and food groups between the two methods. Telenutrition in the form of a smartphone application helps in real-time tracking of dietary details of IBD patients, thus making appropriate interventions and large-scale data acquisition feasible.
RESUMO
BACKGROUND/AIMS: Exclusive enteral nutrition (EEN), an established modality for pediatric Crohn's disease (CD) is seldomly utilized in adults. The present study reports the outcome of EEN in adult CD patients at a tertiary care hospital in India. METHODS: This was a retrospective analysis of CD patients who received EEN as a sole modality/adjunct to other treatment. The primary and secondary outcomes changed in Crohn's Disease Activity Index (CDAI), and clinical response (decline in CDAI > 70), respectively, at 4 and 8 weeks. Subgroup analysis evaluated response across different phenotypes, EEN formulations and prior treatment. Linear mixed effect model was created to assess the predictors of EEN response. RESULTS: Thirty-one CD patients received EEN over median duration of 4 weeks (range, 2-6 weeks). CDAI showed a significant improvement post EEN at 4 (baseline 290 [260-320] vs. 240 [180-280], P= 0.001) and 8 weeks (baseline 290 [260-320] vs. 186 [160-240], P= 0.001), respectively. The cumulative clinical response rates at 4 and 8 weeks were 37.3% and 80.4% respectively. The clinical response rates at 8 weeks across B1 (n = 4), B2 (n = 18) and B3 (n = 9) phenotypes were 50%, 78.8% and 100% respectively (log-rank test, P= 0.093). The response rates at 8 weeks with polymeric (n = 8) and semi-elemental diet (n = 23) were 75% and 82.6%% respectively (log-rank test, P= 0.49). Baseline CDAI (odds ratio, 1.008; 95% confidence interval, 1.002-1.017; P= 0.046) predicted response to EEN. CONCLUSIONS: EEN was effective in inducing clinical response across different phenotypes of CD. Baseline disease activity remained the most important predictor of clinical response to EEN.
RESUMO
BACKGROUND: Sarcopenia and visceral fat independently predict poor outcomes in Crohn's disease (CD). However, combined influence of these parameters on outcomes is unknown, and was investigated in the present study. METHODS: This retrospective study evaluated skeletal muscle index (SMI-cross-sectional area of five skeletal muscles normalized for height), visceral and subcutaneous fat area and their ratio (VF/SC) on single-slice computed tomography (CT) images at L3 vertebrae in CD patients (CT done: January 2012-December 2015, patients followed till December 2019). Sarcopenia was defined as SMI < 36.5 cm2/m2 and 30.2 cm2/m2 for males and females, respectively. Disease severity, behavior, and long-term outcomes (surgery and disease course) were compared with respect to sarcopenia and VF/SC ratio. RESULTS: Forty-four patients [age at onset: 34.4 ± 14.1 years, median disease duration: 48 (24-95) months, follow-up duration: 32 (12-53.5) months, males: 63.6%] were included. Prevalence of sarcopenia was 43%, more in females, but independent of age, disease severity, behavior and location. More patients with sarcopenia underwent surgery (31.6% vs 4%, p = 0.01). VF/SC was significantly higher in patients who underwent surgery (1.76 + 1.31 vs 0.9 + 0.41, p = 0.002), and a cutoff of 0.88 could predict surgery with sensitivity and specificity of 71% and 65% respectively. On survival analysis, probability of remaining free of surgery was lower in patients with sarcopenia (59.6% vs 94.1% p = 0.01) and those with VF/SC > 0.88 (66.1% vs 91.1%, p = 0.1), and still lower in those with both sarcopenia and VF/SC > 0.88 than those with either or none (38% vs 82% vs 100%, p = 0.01). CONCLUSIONS: Combination of sarcopenia and high visceral fat predict worse outcomes in CD than either.
