RESUMO

BACKGROUND & AIMS: The impact of thiopurine de-escalation while on vedolizumab versus continuing thiopurine therapy in ulcerative colitis (UC) is unclear. We aimed to determine the effect of thiopurine withdrawal for patients with UC in remission on vedolizumab. METHODS: This multicenter randomized controlled trial recruited UC patients on vedolizumab 300 mg intravenously every 8 weeks and a thiopurine. Patients in steroid-free clinical remission for ≥6 months and endoscopic remission/improvement (Mayo endoscopic subscore ≤1) were randomized 2:1 to withdraw or continue thiopurine. Primary outcome was comparing week 48 vedolizumab trough concentrations. Secondary outcomes were clinical relapse (partial Mayo score ≥3 and fecal calprotectin >150 µg/g or increase in Mayo endoscopic subscore ≥1 from baseline), fecal calprotectin remission (<150 µg/g), C-reactive protein remission (<5 mg/L), centrally read endoscopic remission (Mayo endoscopic subscore = 0), histologic remission (Nancy index = 0), histo-endoscopic remission, and adverse events. RESULTS: In total, 62 patients were randomized to continue (n = 20) or withdraw (n = 42) thiopurine. At week 48, vedolizumab trough concentrations were not significantly different between continue and withdrawal groups (14.7 µg/mL, interquartile rate [IQR], 12.3-18.5 µg/mL versus 15.9 µg/mL, IQR, 10.1-22.7 µg/mL, respectively, P = 0.36). The continue group had significantly higher fecal calprotectin remission (95.0%, 19/20 versus 71.4%, 30/42; P = .03), histologic remission (80.0%, 16/20 versus 48.6%, 18/37; P = .02), and histo-endoscopic remission (75.0%, 15/20 versus 32.4%, 12/37; P = .002) than the withdrawal group. Histologic activity (hazard ratio [HR], 15.5; 95% confidence interval [CI], 1.6-146.5; P = .02) and prior anti-tumor necrosis factor exposure (HR, 6.5; 95% CI, 1.3-33.8; P = .03) predicted clinical relapse after thiopurine withdrawal. CONCLUSIONS: Thiopurine withdrawal did not affect vedolizumab trough concentrations. However, it may increase fecal calprotectin, histologic, and histo-endoscopic activity. Histologic activity and prior anti-tumor necrosis factor exposure may predict disease relapse on thiopurine withdrawal for patients using vedolizumab for UC.

RESUMO

Patients with inflammatory bowel diseases (IBDs) may require solid organ transplants (SOTs) for multiple reasons, making its prevalence slightly higher than the general population. Although immunosuppression used in SOT may help control IBD-related inflammation, many patients still require additional immunosuppressive medications. We aim to assess the effectiveness and safety of the combination of SOT-related immunosuppression and IBD medications in patients with liver, kidney, or heart transplantation. We conducted a clinical review using PubMed, Scopus, MEDLINE, Embase, and Google Scholar databases for our search. We included data from systematic reviews, meta-analyses, case series, and case reports to assess the safety, effectiveness, and side effect profile of immunomodulators, biologic therapies, and small molecules in patients with SOT. Our review encompassed 25 liver, 6 kidney, and 1 heart transplant studies involving patients with IBD. Common liver transplant immunosuppressants included tacrolimus, mycophenolate mofetil, cyclosporine, and steroids. Anti-TNF agents, widely used in all SOT types, showed no significant safety issues, though infections and malignancies were noted. Patients with liver transplant on tacrolimus responded well to anti-integrins and ustekinumab without major complications. For kidney transplants, cyclosporine and tacrolimus were prevalent, and their combination with anti-TNF or ustekinumab was generally safe, with rare reports of malignancy or infection. Hence, the use of anti-TNF, anti-integrin agents, and ustekinumab appears to be safe in patients with SOT, regardless of their transplant related immunosuppression. More studies are needed in patients with kidney and heart transplants and in patients treated with small molecules for their IBD.

RESUMO

BACKGROUND: The effect of radiation on the ileal pouch is less well studied in patients with inflammatory bowel disease (IBD) and ileal pouch-anal anastomosis. AIMS: This retrospective study investigates the impact of external radiation therapy on the outcomes of ileal pouches. METHODS: The study included 82 patients with IBD and ileal pouches, of whom 12 received pelvic radiation, 16 abdominal radiation, 14 radiation in other fields, and 40 served as controls with no radiation. Pouch-related outcomes, including pouch failure, worsening of symptoms, pouchitis, and development of strictures, along with changes in Pouch Disease Activity Index (PDAI) scores pre- and post-radiation were assessed. RESULTS: The pelvic radiation group exhibited a significantly higher rate of pouch failure (25%, p < 0.004) and worsening pouch-related symptoms (75%, p = 0.012) compared to other groups. Although not statistically significant, a higher incidence of pouchitis was observed in the pelvic radiation group (45.5%, p = 0.071). Strictures were more common in the pelvic radiation group (25%, p = 0.043). Logistic regression analysis revealed that pelvic radiation significantly increased the odds of pouch-related adverse outcomes (OR 5.66; 95% confidence interval: 1.61-21.5). CONCLUSION: Pelvic radiation significantly impacts the outcomes of ileal pouches in patients with IBD, increasing the risk of pouch failure, symptom exacerbation, and structural complications. These findings underscore the need for careful consideration of radiation therapy in this patient population and highlight the importance of closely monitoring and managing radiation-induced pouch dysfunction.

RESUMO

GOALS AND BACKGROUND: We aimed to develop a novel 1-year mortality risk-scoring system that includes use of antithrombotic (AT) drugs and to validate it against other scoring systems in patients with acute gastrointestinal bleeding (GIB). STUDY: We developed a risk-scoring system from prospectively collected data on patients admitted with GIB between January 2013 and August 2020, who had at least 1- year of follow-up. Independent predictors of 1-year mortality were determined after adjusting for the following confounders: the age-adjusted Charlson Comorbidity Index (CCI) (divided into 4 groups: CCI-0=0, CCI-1=1 to 3, CCI-2=4 to 6, CCI-3 ≥7), need for blood transfusion, GIB severity, need for endoscopic therapy, and type of AT. The risk score was based on independent predictors. RESULTS: Five hundred seventy-six patients were included and 123 (21%) died at 1-year follow-up. Our risk -score was based on the following: CCI-2 (2 points), CCI-3 (4 points), need for blood transfusion (1 point), and no use of aspirin (1 point), as aspirin use was protective (maximum score=6). Patients with higher risk scores had higher mortality. The model had a better predictive accuracy [AUC=0.82, 95% confidence interval (0.78-0.86), P <0.0001] than the Rockall score for upper GIB (Area Under the Curve (AUC)=0.68, P <<0.0001), the Oakland score for lower GIB (AUC=0.69, p =0.004), or the Shock Index for all (AUC=0.54, P <0.0001). CONCLUSION: A simple and novel score that includes use of AT upon admission accurately predicts 1-year mortality in patients with GIB. This scoring system may help guide follow-up decisions and inform the prognosis of patients with GIB.

RESUMO

PURPOSE OF REVIEW: Since there is a lack of head-to-head randomized controlled trials, little direction is provided from guidelines on the positioning of biologics for the treatment of Crohn's disease (CD). This review utilizes comparative effectiveness and safety results from real-world data and network meta-analyses to inform clinical practice for positioning of biological therapies in the treatment of moderate-to-severe CD. RECENT FINDINGS: We summarize the results of studies pertaining to the identification of predictors for response to biologics in CD. Recently published studies about the management of moderate-to-severe CD are discussed and a positioning algorithm is proposed for the therapeutic approach of these patients. SUMMARY: Different classes of biologics are comparable with regards to safety and almost similar in effectiveness in the management of CD. There are certain clinical scenarios in which one biologic is more effective than another. For instance, patients with a more aggressive disease phenotype such as fistulizing disease would benefit from infliximab over other biologics, whereas in older patients at a higher risk for infectious complications, it may be more appropriate to use ustekinumab or vedolizumab over the anti-tumor necrosis factor (TNF) agents. More data pertaining to identifying predictors of response to the different available therapies and head-to-head comparison trials are needed to personalize our therapeutic approach of CD patients.

RESUMO

The therapeutic armamentarium for patients with inflammatory bowel disease has been expanding. Current guidelines make recommendations about whether patients who are biologic naive should be receiving biologic monotherapy or combination therapy, depending on the class of biologics. However, due to the limited available data, guidance to inform clinical practice for patients receiving their second or more biologic are lacking. We hereby review the available data about the use of biologic monotherapy or combination therapy with concomitant immunomodulator therapies in patients receiving their first as well as those receiving their second biologic.

RESUMO

Nutrients in the lumen of the small intestine are sensed by special cells in the epithelial lining. The ensuing neurohumoral reflexes affect gastrointestinal absorption/secretion, motility, and vascular perfusion. To study in vivo the effect of a monosaccharide (glucose) or polysaccharide (starch) present in the jejunum on glucose absorption from an adjacent part of the intestine and investigate the possible underlying mechanisms. Using the single pass intraluminal perfusion technique, a segment of jejunum (perfusion segment) was continuously perfused with 20 mM glucose to determine glucose absorption. One hour later, a bolus of a saccharide was instilled in an isolated adjacent jejunal segment and the change in glucose absorption was monitored for a further 2 h. The contribution of neural mechanisms in this process was investigated. Instillation of glucose (20 mM or 40 mM) in either distal or proximal jejunal pouch elicited immediate and sustained inhibition of glucose absorption (a decrease by 25%; P < 0.01) from the perfused jejunal segment. Comparable inhibition was obtained with instillation of other monosaccharides or starch in the jejunal pouch. This inhibition was abolished by adding tetrodotoxin to the pouch or to the perfused jejunal segment and also by pretreatment with sympathetic blockers (guanethidine or hexamethonium) and by chemical ablation of capsaicin-sensitive primary afferent fibers. Glucose absorption within the jejunum is auto-regulated through backward and forward mechanisms. This regulation is mediated by neural reflexes involving capsaicin-sensitive afferent and sympathetic efferent fibers. These reflexes might serve to protect against hyperglycemia.

RESUMO

Despite the recent advances in endoscopic hemostatic techniques, the management of lower gastrointestinal bleeding could be sometimes challenging. Hemostatic powders such as Hemospray, EndoClot, and Ankaferd Blood Stopper have found their way into digestive endoscopy and are licenced in many countries especially for use in upper gastrointestinal bleeding. We reviewed the literature on the use of these hemostatic powders in different situations in lower gastrointestinal bleeding and looked at the success rate and rebleeding rate. Most of the data are derived from case reports, retrospective and prospective case series with absence of any randomized controlled trials. Hemostatic powders were used as primary or salvage therapy to control bleeding from polypectomy site, colonic tumors, diverticula, arteriovenous malformations, radiation proctitis, ischemic colitis, and surgical intestinal anastomosis. The rate of immediate control of bleeding is in the range of 88-100% with a recurrence rate of 3-13% except for radiation proctitis bleeding where rebleeding rate can be as high as 77%. Although there are many advantages for the use of local hemostatic agents in lower gastrointestinal bleeding, future randomized controlled trials comparing them with conventional methods are needed.

RESUMO

Crohn's disease (CD) is a chronic relapsing and remitting disease that can affect any segments of the gastrointestinal tract. More than 50% of patients with CD develop stricturing or penetrating complications within the first 10 years after diagnosis. Strictures can lead to intestinal obstruction, which is a common indication for surgery. Despite significant advances in the understanding of the pathogenesis of intestinal fibrostenosis, imaging and therapeutic armamentarium of CD, the risk of intestinal surgery remained significantly high. Endoscopic balloon dilation is a promising first-line alternative to surgery as it is less invasive and could preserve intestinal length. In this review, we will evaluate the literature on the mechanism of intestinal fibrosis, emerging imaging techniques, and management strategies for CD associated strictures.

RESUMO

Recently, proteomics studies have provided important information on the role of proteins in health and disease. In the domain of inflammatory bowel disease, proteomics has shed important light on the pathogenesis and pathophysiology of inflammation and has contributed to the discovery of some putative clinical biomarkers of disease activity. By being able to obtain a large number of specimens from multiple sites and control for confounding environmental, genetic, and metabolic factors, proteomics studies using animal models of colitis offered an alternative approach to human studies. Our aim is to review the information and lessons acquired so far from the use of proteomics in animal models of colitis. These studies helped understand the importance of different proteins at different stages of the disease and unraveled the different pathways that are activated or inhibited during the inflammatory process. Expressed proteins related to inflammation, cellular structure, endoplasmic reticulum stress, and energy depletion advanced the knowledge about the reaction of intestinal cells to inflammation and repair. The role of mesenteric lymphocytes, exosomes, and the intestinal mucosal barrier was emphasized in the inflammatory process. In addition, studies in animal models revealed mechanisms of the beneficial effects of some therapeutic interventions and foods or food components on intestinal inflammation by monitoring changes in protein expression and paved the way for some new possible inflammatory pathways to target in the future. Advances in proteomics technology will further clarify the interaction between intestinal microbiota and IBD pathogenesis and investigate the gene-environmental axis of IBD etiology.

RESUMO

BACKGROUND: Colitis is associated with functional abnormalities in proximal non-inflamed gut areas, but animal models to study small bowel dysfunction in colitis have limitations. This study aims to determine small intestinal alanine absorption and cytokine expression in a novel model of colonic ulceration induced by electro-cautery. METHODS: A descending colon ulcer was induced in rats by a bipolar electro-cautery probe. Ulcer score was determined using Satoh's criteria. Jejunal alanine absorption was measured immediately and at different time intervals post ulcer induction. Levels of interleukin-1 (IL-1), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) protein and m-RNA were determined in mucosal scrapings obtained from the colon, duodenum, jejunum and ileum at various time intervals after colonic ulcer induction. RESULTS: The mean ulcer score was 3 up to 48h, followed by healing by 96h post ulcer induction. Small bowel histology was normal throughout. Jejunal alanine absorption was reduced by 12-34% immediately and up to 72h after cautery and returned to normal at 96h. IL-1 and TNF-α mRNA increased significantly in the colon, duodenum, jejunum and ileum 3h post electro-cautery and returned to normal at 48h, while that of IL-6 increased significantly at 48h post ulcer induction. Similarly, IL-1, IL-6 and TNF-α protein levels increased in the duodenum, jejunum, ileum and colon up to 48h post ulcer induction. CONCLUSIONS: Electrically induced localized colonic injury increased production of pro-inflammatory cytokines in non-inflamed segments of the small intestine and was associated with derangements of jejunal absorptive function.

RESUMO

BACKGROUND AND STUDY AIMS: Celiac disease is increasingly recognized worldwide, but guidelines on how to detect the condition and diagnose patients are unclear. In this study the prevalence and predictors of celiac disease were prospectively determined in a cross-sectional sample of Lebanese patients undergoing esophagogastroduodenoscopy (EGD). PATIENTS AND METHODS: Consecutive consenting patients (n = 999) undergoing EGD answered a questionnaire and had blood taken for serologic testing. Endoscopic markers for celiac disease were documented and duodenal biopsies were obtained. The diagnosis of celiac disease was based on abnormal duodenal histology and positive serology. Risk factors were used to classify patients to either high or low risk for celiac disease. Independent predictors of celiac disease were derived via multivariate logistic regression. RESULTS: Villous atrophy (Marsh 3) and celiac disease were present in 1.8 % and 1.5 % of patients, respectively. Most were missed on clinical and endoscopic grounds. The sensitivity of tissue transglutaminase (tTG) testing for the diagnosis of villous atrophy and celiac disease was 72.2 % and 86.7 %, respectively. The positive predictive value of the deamidated gliadin peptide (DGP) test was 34.2 % and that of a strongly positive tTG was 80 %. While the strongest predictor of celiac disease was a positive tTG (odds ratio [OR] 131.7, 95 % confidence interval [CI] 29.0 - 598.6), endoscopic features of villous atrophy (OR 64.8, 95 %CI 10.7 - 391.3), history of eczema (OR 4.6, 95 %CI 0.8 - 28.8), anemia (OR 6.7, 95 %CI 1.2 - 38.4), and being Shiite (OR 5.4, 95 %CI 1.1 - 26.6) significantly predicted celiac disease. A strategy of biopsying the duodenum based on independent predictors had a sensitivity of 93 % - 100 % for the diagnosis of celiac disease, with an acceptable (22 % - 26 %) rate of performing unnecessary biopsies. A strategy that excluded pre-EGD serology produced a sensitivity of 93 % - 94 % and an unnecessary biopsy rate of 52 %. CONCLUSION: An approach based solely on standard clinical suspicion and endoscopic findings is associated with a significant miss rate for celiac disease. A strategy to biopsy based on the derived celiac disease prediction models using easily obtained information prior to or during endoscopy, maximized the diagnosis while minimizing unnecessary biopsies.

RESUMO

Brunner's gland hamartoma (BGH) is a rare, benign tumor of the duodenum. It is mostly asymptomatic and usually found incidentally on routine esophagogastroduodenoscopy (EGD). However, some BGHs present with major complications including anemia, bleeding, obstruction, or dysplasia, requiring management and resection of these lesions. Herein, we present two cases of large BGHs of the duodenum, one presenting as severe gastrointestinal bleeding and the other, noted on EGD for iron deficiency anemia, found to have high grade dysplasia. This literature review discusses the rare serious complications of BGH, including iron deficiency anemia, overt gastrointestinal bleeding, and malignant potential.

RESUMO

BACKGROUND: Despite the growing therapeutic armamentarium, at least half of the patients with Crohn's disease will require surgery during their lifetime. Current evidence for the prevention and treatment of postoperative Crohn's disease supports the use of anti-tumor necrosis factor agents with limited data about the use of the newer biologics, vedolizumab and ustekinumab. METHODS: We performed a systematic review of available data to determine the efficacy of the newer biologics in the management of postoperative Crohn's disease. We included noncomparative and comparative studies. The main outcomes of interest were clinical and endoscopic postoperative recurrence rates. RESULTS: The search strategy identified 1231 citations, with 32 eligible for review. Several studies showed that the postoperative Crohn's disease recurrence rates with the use of the newer biologics were comparable to previously published results with the use of anti-tumor necrosis factor agents, while other studies failed to show their efficacy. It is important to note that the studies were heterogeneous and included a relatively small sample size, making it difficult to draw a definite conclusion about the efficacy of the newer biologics in the management of postoperative Crohn's disease. CONCLUSION: The newer biologics do play a role in the management of postoperative Crohn's disease. After our review, we proposed an updated algorithm on the role of newer biologics in the approach to patients with postoperative Crohn's disease. Yet, until we have better-designed studies, their definite positioning remains to be determined.


Review of the literature showed some encouraging results on the effectiveness of vedolizumab and ustekinumab in the prevention and treatment of postoperative Crohn's disease. However, more controlled studies comparing the new biologic agents with anti-tumor necrosis factor agents are needed.

RESUMO

Background: The incidence of colonic adenomas and colorectal cancer has been on the rise among young patients. In this study, we aimed to describe the characteristics of young patients (<50 years) with adenomatous polyps and to characterize those polyps. We also aimed to determine appropriate surveillance intervals for young patients. Methods: We performed a retrospective chart review of patients <50 years of age who had polypectomy of 1 or more adenomatous polyps on colonoscopy between 2008 and 2021. Patient demographics, colonoscopy indication and polyp characteristics were obtained from the chart. Timing and findings on surveillance colonoscopies were recorded. Results: A total of 610 patients were included: mean age 42.9±5.9 years, 61% males, body mass index 27.5±4.7 kg/m2, and over 50% smokers. The most common indications were abdominal pain (23.3%), rectal bleeding (22.3%), and change in bowel habits (17.6%). Almost half of the patients who had adenomas (299) were younger than 45 years. Tubular adenoma was the most frequently encountered type of polyp (571; 93.6%). Mean polyp size was 1.1±0.9 cm. The most common location of adenomas was the sigmoid colon (41%). Of patients with adenomas, 156 (26%) had surveillance colonoscopy within 2.9±2.3 years; 74 patients (47.4%) were found to have new adenomas. Conclusions: Patients aged <50 years with colonic adenomas were mostly males, overweight, and smokers. Further adenomas were found in 47% of surveillance colonoscopies, and most were encountered within 5 years. High rates of recurrent adenomas in people <50 years of age may warrant frequent surveillance.

RESUMO

Background: The aim of this study was to investigate the impact of blood transfusion (BT) on mortality and rebleeding in patients with gastrointestinal bleeding (GIB) and whether BT at a threshold of ≤7 g/dL may improve these outcomes. Methods: A prospective study was conducted in patients admitted with GIB between 2013 and 2021. Antithrombotic (AT) use and clinical outcomes were compared between transfused and non-transfused patients, and between those transfused at a threshold of ≤7 vs. >7 g/dL. Multivariate analysis was performed to identify predictors of mortality and rebleeding. Results: A total of 667 patients, including 383 transfused, were followed up for a median of 56 months. Predictors of end-of-follow-up mortality included: age-adjusted Charlson Comorbidity Index, stigmata of recent hemorrhage (SRH), and being on anticoagulants only upon presentation (P=0.026). SRH was a predictor of end-of-follow-up rebleeding, while having been on only antiplatelet therapy (AP) upon presentation was protective (P<0.001). BT was not associated with mortality or rebleeding at 1 month or end of follow up. Among transfused patients, being discharged only on AP protected against mortality (P=0.044). BT at >7 g/dL did not affect the risk of short or long-term rebleeding or mortality compared to BT at ≤7 g/dL. Conclusions: Short- and long-term mortality and rebleeding in GIB were not affected by BT, nor by a transfusion threshold of ≤7 vs. >7 g/dL, but were affected by the use of AT. Further studies that account for AT use are needed to determine the best transfusion strategy in GIB.

RESUMO

INTRODUCTION: Diet is thought to play an important role in the clinical course and quality of life (QOL) of patients with inflammatory bowel disease (IBD). However, dietary habits of patients with IBD are still unknown. This case-control study aims to compare the dietary habits of patients with IBD to healthy controls and evaluate differences in disease severity and QOL. MATERIALS AND METHODS: Food frequency, severity scores using the Harvey-Bradshaw and Ulcerative colitis activity index, and QOL were assessed using online questionnaires. Dietary habits were compared for patients with active disease and remission and for those with low QOL (LQOL) and high QOL (HQOL). RESULTS: We recruited 61 patients with IBD and 101 controls. Significance was set at p = 0.05. Controls consumed significantly more daily calories (2546 vs. 1641, p = 0.001). However, patients with IBD consumed a higher percentage of carbohydrates (50% vs. 45%, p = 0.001), more red meat (p = 0.024), and less fiber, sucrose, and lactose (p = 0.001, 0.001, and 0.036). Patients with active disease had higher lipid intake, lower protein intake, and lower QOL (47 vs. 58, p = 0.001). Dietary differences between LQOL and HQOL mirrored those between active disease and remission. CONCLUSION: This study is the first to provide valuable insights into the nutritional profile of Lebanese patients with IBD.

RESUMO

Background: The epidemiology of inflammatory bowel disease (IBD) has changed rapidly in recent years. Objective data concerning the IBD burden in the Middle East and North Africa (MENA) region is limited. We aimed to provide a systematic report on the IBD burden in the MENA region. Additionally, we aimed to study the age- and sex-specific trends in IBD incidence, prevalence and mortality rates from 1990-2019. Methods: Using the Global Burden of Disease (GBD) 2019 Study Database, we investigated the changes in incidence, prevalence and mortality rate, and disability-adjusted life-years (DALYs), at a regional and country level between 1990 and 2019. Results: In 2019, there were 282,534 cases (95% confidence interval [CI] 239,506-334,478) of IBD in the MENA region (50.5% male). There was an overall increase in the incidence and prevalence rates of IBD in the MENA region from 1990 to 2019, while a simultaneous decrease in overall mortality rates was identified. Incidence rates were highest in Jordan, at 6.9 (95%CI 5.8-8.1) per 100,000, and lowest in Morocco, at 1.6 (95%CI 1.4-2) per 100,000. From 1990-2019, the incidence was found increased in males at a higher rate than in females. The age-standardized mortality rate decreased for both sexes by 24% from 1990-2019. Conclusion: The trends and geographic variations in IBD within the MENA region provide policymakers with vital information for making informed decisions in policy, research, and investment, thereby enabling the development of more effective strategies and better allocation of resources.
