Serrated Polyps in Inflammatory Bowel Disease Indicate a Similar Risk of Metachronous Colorectal Neoplasia as in the General Population.

BACKGROUND: The risk of metachronous advanced neoplasia after diagnosing serrated polyps in patients with IBD is poorly understood. METHODS: A retrospective multicenter cohort study was conducted between 2010 and 2019 at three tertiary centers in Montreal, Canada. From pathology databases, we identified 1587 consecutive patients with serrated polyps (sessile serrated lesion, traditional serrated adenoma, or serrated epithelial change). We included patients aged 45-74 and excluded patients with polyposis, colorectal cancer, or no follow-up. The primary outcome was the risk of metachronous advanced neoplasia (advanced adenoma, advanced serrated lesion, or colorectal cancer) after index serrated polyp, comparing patients with and without IBD. RESULTS: 477 patients with serrated polyps were eligible (mean age 61 years): 37 with IBD, totaling 45 serrated polyps and 440 without IBD, totaling 586 serrated polyps. The median follow-up was 3.4 years. There was no difference in metachronous advanced neoplasia (HR 0.77, 95% CI 0.32-1.84), metachronous advanced adenoma (HR 0.54, 95% CI 0.11-2.67), and metachronous advanced serrated lesion (HR 0.76, 95% CI 0.26-2.18) risk. When comparing serrated polyps in mucosa involved or uninvolved with IBD, both groups had similar intervals from IBD to serrated polyp diagnosis (p > 0.05), maximal therapies (p > 0.05), mucosal inflammation, inflammatory markers, and fecal calprotectin (p > 0.05). CONCLUSION: The risk of metachronous advanced neoplasia after serrated polyp detection was similar in patients with and without IBD. Serrated polyps in IBD occurred independently of inflammation. This helps inform surveillance intervals for patients with IBD diagnosed with serrated polyps.

Burden of Mental Health among Patients with Inflammatory Bowel Disease-A Cross-Sectional Study from a Tertiary IBD Center in Hungary.

Background: Inflammatory bowel diseases (IBDs) are chronic conditions that negatively affect the patient's quality of life. With the spread of the biopsychosocial model, the role of mental health in the activity and course of inflammatory bowel disease is becoming more and more recognized. Our study aimed to assess the prevalence of anxiety and depression in IBD patients in our tertiary referral center and determine the predictive factors of these mental conditions. Methods: A total of 117 patients were included consecutively between 1 December 2021 and 28 February 2022. We used a questionnaire to gather demographic information, disease course, and IBD-specific symptoms. We assessed anxiety symptoms using the GAD-7 and depressive complaints using the PHQ-9 questionnaire. We evaluated disease activity using CDAI and pMayo scores. Results: Of the 117 patients (male/female: 63/54), 88 suffered from Crohn's disease, and 29 were diagnosed with ulcerative colitis. Only 6 patients were taking medication for mood disorders, and 38 individuals sought mental support during their lifetime. A total of 15% of the population suffered from moderate-severe anxiety disorder, and 22% were affected by moderate-severe depression. The GAD-7 and PHQ9 values showed a significant correlation between the number of stools, bloody stools, abdominal pain, number of flare-ups, and CDAI scores. Conclusions: Our study confirmed that there is a high incidence of anxiety and depressive symptoms among IBD patients. Our results highlighted the symptoms that could be associated with mental disorders. It is important to assess the mental status of IBD patients to improve their quality of life.

Accuracy of the Pancolonic Modified Mayo Score in predicting the long-term outcomes of ulcerative colitis: a promising scoring system.

Background: Different endoscopic scoring systems for assessing ulcerative colitis (UC) severity are available. However, most of them are not correlated with disease extent. Objectives: Our study aimed to compare the predictive value of the PanMay score versus the endoscopic Mayo (MES), Ulcerative Colitis Endoscopic Index of Severity (UCEIS), and Dublin score in predicting long-term outcomes of UC. Design: This retrospective study enrolled consecutive UC patients who underwent colonoscopy before at least a 3-year follow-up. Methods: The PanMayo, MES, UCEIS, and Dublin scores and the baseline clinical and demographic characteristics of the participants were assessed. Endpoints were disease flare that required novel biological therapy, colectomy, and hospitalization. Patients were stratified using baseline clinical activity. Results: Approximately 62.8% of the 250 enrolled patients were in clinical remission. In these patients, the PanMayo, MES, and Dublin scores were positively associated with the risk of clinical flare. The MES score increased with clinical flare. The PanMayo score (>12 points), but not the MES score, was associated with the need for novel biological initiation and biological escalation. Furthermore, the Dublin and UCEIS scores of patients in remission who need novel biological treatment had a similar trend. Colectomy risk was associated with PanMayo and Dublin scores. Conclusion: The combined endoscopic assessment of disease extent and severity can be more accurate in predicting outcomes among patients with UC. PanMayo score can be utilized in addition to the existing scoring systems, thereby leading to a more accurate examination. Summary: UC endoscopic scores do not assess extension. Our study aimed to analyze the predictive value of the PanMayo score. Based on 250 patients, results showed that the long-term disease outcomes of UC could be predicted with the PanMayo score more accurately.

Current Evidence for Combined Targeted Therapy for the Treatment of Inflammatory Bowel Disease.

Biologicals and small molecules have revolutionized the medical management of inflammatory bowel diseases (IBD), yet they are only effective in a proportion of patients, and their impact on changing the natural history of the disease is still debatable. Recently, the concept of combining targeted biologics and small-molecule therapies has been introduced to the treatment of IBD. Dual-targeted therapy (sequential and combined), which is the combination of two targeted therapies, might be a reasonable choice for patients to break through the therapeutic ceiling. A recent randomized clinical trial (VEGA) provided the first controlled evidence that the short-term combination of two biological agents may lead to superior disease control than either of the agents alone in patients with ulcerative colitis (UC) without jeopardizing safety. Multiple studies are underway in both Crohn's disease and UC. Additionally, real-world evidence is accumulating in IBD patients receiving combination therapies with concomitant IBD and extraintestinal manifestations or in patients with medically refractory IBD. Of note, the majority of these patients were exposed to multiple biological agents earlier and lost response to at least one of the agents in the combination. This review summarizes current knowledge regarding this attractive novel therapeutic option in IBD. Clearly, more controlled data are needed to evaluate optimal timing, efficacy, and mitigation of safety concerns.

Novel and emerging drugs for the treatment of Crohn's disease: a review of phase II and III trials.

INTRODUCTION: Crohn's disease (CD) is a chronic inflammatory bowel disease characterized by unpredictable flare-ups and periods of remission. While several therapeutic options, such as anti-tumor necrosis factor (TNF), anti-integrin, and interleukin (IL) 12/23 inhibitors, as well as IL-23 and Janus kinase (JAK) inhibitors, have been approved for CD treatment, a substantial number of patients fail to respond adequately or experience a loss of response over time. In recent years, the scientific community has been actively investigating novel agents to address these challenges and improve the management of CD. AREAS COVERED: This comprehensive narrative review provides an overview of recent developments in CD treatment, summarizing phase 2 and phase 3 clinical trial data. We delve into the clinical efficacy and safety profiles of emerging therapies, encompassing JAK inhibitors, IL-23 inhibitors, anti-adhesion molecules, S1P1 receptor modulators, and combined targeted treatments. EXPERT OPINION: The armamentarium of CD therapeutic agents is constantly expanding. We analyze pivotal findings from phase 2 and phase 3 CD treatment trials. We also underscore the existing gaps in therapy and the paramount role of ongoing research and innovation in CD management.

Clinical efficacy and nocebo effect following non-medical biosimilar switch in patients with inflammatory bowel disease: A prospective observational study.

BACKGROUND: We aimed to evaluate clinical efficacy, biomarker activity, therapeutic drug monitoring (TDM), adverse events (AEs), and nocebo effect in inflammatory bowel disease (IBD) patients who underwent non-medical biosimilar switching. METHODS: A prospective observational study of consecutive IBD patients who underwent biosimilar switch. Disease activity, biomarkers, TDM, and AEs, including the nocebo effect were captured 8 weeks before switch, at the time of switch (baseline),12 and 24 weeks after the switch. RESULTS: 210 patients were included [81.4% had Crohn's disease (CD), the median age at inclusion: 42 years (IQR 29-61)]. There was no significant difference in the rates of clinical remission at week 8 before switch, baseline, week12, and 24 after switch: 89.0%,93.4%,86.3%,and 90.8%,p = 0.129. The biomarker remission rates were not significantly different; CRP:81.3%,74.7%,81.2%,73.0%,p = 0.343; fecal calprotectin: 78.3%,74.5%,71.7%,76.3%,p = 0.829. The rates of maintaining therapeutic levels (84.7%,83.9%,83.0%,85.3%,p = 0.597) and prevalence of positive anti-drug antibodies remained unchanged. Drug persistence at 12 week of switch was 97.1%, regardless of disease phenotype and originator. The nocebo effect was observed in 13.3%. The discontinuation rate was 4.8%. CONCLUSION: Despite a significant number of early nocebo complaints within the first 6 months after the biosimilar switch, no significant changes were found in clinical efficacy, biomarkers, therapeutic drug level, or anti-drug antibodies.

Burden of perianal disease in Crohn's disease: Accelerating medical therapy and high rates of perianal surgery over the last four decades - Results from a population-based study over four decades.

BACKGROUND: Few population-based studies have investigated the prevalence and disease course of perianal manifestation in Crohn's disease. AIMS: To analyse the prevalence and outcomes of perianal Crohn's disease including medical therapies and need for perianal surgery, over different therapeutic eras based on the time of diagnosis; cohort A (1977-1995), cohort B (1996-2008), and cohort C (2009-2018) METHODS: Patient inclusion lasted between 1977 and 2018. We followed patients prospectively, and regularly reviewed both in-hospital and outpatient records. We defined a perianal surgical procedure as any perianal incision and excision, fistulotomy, or abscess drainage. RESULTS: We included 946 incident patients. Perianal disease at diagnosis was present in 17.4% (n = 165) of the total cohort, with a declining prevalence in cohorts A/B/C, respectively (24.7%/18.5%/13.2%; p = 0.001). By the end of follow-up, an additional 9.3% (n = 88) of the total cohort developed perianal disease. Cumulative immunosuppressive and biologic exposure increased over time; biologic use was higher in patients with perianal disease [pLog Rank < 0.001]. The overall rate of perianal surgery was 44.7% (113/253), with a probability of 28.3% (95% CI: 25.4-31.2) after 10 years, 41.0% (95% CI: 37.5-44.5) after 20 years, and 64.1% (95% CI: 59-69.2) after 30 years. There was no statistically significant difference in the probability of first perianal surgery among cohorts A/B/C [Log Rank = 0.594]. CONCLUSIONS: The burden of perianal disease and perianal surgery rates were high in this cohort. Therapeutic strategy was accelerated in patients with perianal Crohn's over time with higher exposure to immunosuppressives and biologics. Surgical management of perianal disease remained unchanged amongst the cohorts.

Monitoring of Inflammatory Bowel Disease in Pregnancy: A Review of the Different Modalities.

Inflammatory Bowel Disease (IBD) significantly affects women in their reproductive years. Understanding the relationship between IBD and pregnancy is crucial, given its impact across pre-gestational, gestational, and postpartum phases. Monitoring IBD activity during pregnancy involves various modalities. This review discusses these modalities, focusing on the efficacy and safety of Small Intestine Ultrasound (IUS) as a noninvasive and reliable option. While IUS has gained popularity, its technique-sensitive nature necessitates trained staff for optimal usage.

Real-Life Efficacy of Tofacitinib in Various Situations in Ulcerative Colitis: A Retrospective Worldwide Multicenter Collaborative Study.

BACKGROUND AND AIMS: Tofacitinib (TFB) appears to be effective in the treatment of ulcerative colitis (UC); however, available real-world studies are limited by cohort size. TFB could be an option in the treatment of acute severe ulcerative colitis (ASUC). We aimed to investigate efficacy and safety of TFB in moderate-to-severe colitis and ASUC. METHODS: This retrospective, international cohort study enrolling UC patients with ≥6-week follow-up period was conducted from February 1 to July 31, 2022. Indications were categorized as ASUC and chronic activity (CA). Baseline demographic and clinical data were obtained. Steroid-free remission (SFR), colectomy, and safety data were analyzed. RESULTS: A total of 391 UC patients (median age 38 [interquartile range, 28-47] years; follow-up period 26 [interquartile range, 14-52] weeks) were included. A total of 27.1% received TFB in ASUC. SFR rates were 23.7% (ASUC: 26.0%, CA: 22.8%) at week 12 and 41.1% (ASUC: 34.2%, CA: 43.5%) at week 52. The baseline partial Mayo score (odds ratio [OR], 0.850; P = .006) was negatively associated with week 12 SFR, while biologic-naïve patients (OR, 2.078; P = .04) more likely achieved week 52 SFR. The colectomy rate at week 52 was higher in ASUC group (17.6% vs 5.7%; P < .001) and decreased with age (OR, 0.94; P = .013). A total of 67 adverse events were reported, and 17.9% resulted in cessation of TFB. One case of thromboembolic event was reported. CONCLUSIONS: TFB is effective in both studied indications. TFB treatment resulted in high rates of SFR in the short and long terms. Higher baseline disease activity and previous biological therapies decreased efficacy. No new adverse event signals were found.

Declining Trends of Reoperations and Disease Behaviour Progression in Crohn's Disease over Different Therapeutic Eras-A Prospective, Population-Based Study from Western Hungary between 1977-2020, Data from the Veszprem Cohort.

BACKGROUND AND AIMS: Few population-based studies have investigated long-term surgery rates for Crohn's disease [CD]. Our aim was to analyse disease progression and surgery rates in a population-based cohort over different therapeutic eras, based on the time of diagnosis: cohort-A [1977-1995], cohort-B [1996-2008], and cohort-C [2009-2018]. METHODS: A total of 946 incident CD patients were analysed (male/female: 496/450; median age at diagnosis: 28 years [y]; interquartile range [IQR]: 22-40]). Patient inclusion lasted between 1977 and 2018. Immunomodulators have become widespread in Hungary since the mid-1990s and biologic therapies since 2008. Patients were followed prospectively, with both in-hospital and outpatient records reviewed regularly. RESULTS: The probability of disease behaviour progression from inflammatory [B1] to stenosing or penetrating phenotype [B2/B3] significantly decreased (27.1 ±â€…5.3%/21.5 ±â€…2.5%/11.3 ±â€…2.2% in cohorts A/B/C, respectively, after 5 years; 44.3 ±â€…5.9%/30.6 ±â€…2.8%/16.1 ±â€…2.9% after 10 years, respectively; [pLogRank <0.001]). The probability of first resective surgery between cohorts A/B/C were 33.3 ±â€…3.8%/26.5 ±â€…2.1%/28.1 ±â€…2.4%, respectively, after 5 years; 46.1 ±â€…4.1%/32.6 ±â€…2.2%/33.0 ±â€…2.7% after 10 years, respectively; and 59.1 ±â€…4.0%/41.4 ±â€…2.6% [cohorts A/B] after 20 years. There was a significant decrease in first resective surgery risk between cohorts A and B [plog rank = 0.002]; however, no further decrease between cohorts B and C [plog rank = 0.665]. The cumulative probability of re-resection in cohorts A/B/C was decreasing over time (17.3 ±â€…4.1%/12.6 ±â€…2.6%/4.7 ±â€…2.0%, respectively, after 5 years [plog rank = 0.001]). CONCLUSION: We report a continuous decline in reoperation rates and disease behaviour progression in CD over time, with the lowest values in the biologic era. In contrast, there was no further decrease in the probability of first major resective surgery after the immunosuppressive era.

Mucosal Healing and Clinical Efficacy of Adalimumab in Small Intestinal Crohn's Disease (SIMCHA Study): Final Results From a Prospective, Open-Label, Single-Arm Study.

BACKGROUND: Endoscopic healing is a key treatment target in inflammatory bowel disease; few data are available on the clinical and endoscopic efficacy of biological therapy in upper gastrointestinal Crohn's disease. This study aimed to investigate small bowel mucosal healing and clinical efficacy of adalimumab therapy by video capsule endoscopy in patients with endoscopically active upper gastrointestinal Crohn's disease. METHODS: This prospective, open-label, single-arm study included Crohn's disease patients with moderate-severe endoscopic proximal small bowel involvement, defined by a Lewis score >790. Patients were treated with adalimumab monotherapy for 24 weeks. Co-primary outcomes were endoscopic healing, defined as Lewis score <350, and endoscopic response, defined as >50% decrease in Lewis score. Secondary outcomes included clinical (Harvey-Bradshaw index <4) and biomarker remission (fecal calprotectin <250 µg/g, and C-reactive protein <5 mg/L). RESULTS: A total of 59 Crohn's disease patients were screened; 17 patients have met eligibility criteria and were enrolled. Endoscopic healing was observed in 8 patients (47.1%) and endoscopic response in additional 5 patients (29.4%) at 24 weeks. Median Lewis score was significantly decreased compared to baseline (1912 vs. 337, P = .0005). Eleven of 13 patients (84.6%) with clinical activity achieved clinical remission (baseline: 13/17 vs. week 24: 2/17, P < .0001). Nine of 10 patients with elevated C-reactive protein achieved normal C-reactive protein after treatment and the median C-reactive protein significantly decreased from 7.4 to 1.6 mg/L, P = .032. In contrast, no change was observed in fecal calprotectin pre- and posttreatment. CONCLUSIONS: Adalimumab induced endoscopic healing and clinical remission in patients with active small bowel Crohn's disease, with approximately half of the patients achieving endoscopic healing.

Health utilities and willingness to pay in adult patients with coeliac disease in Hungary.

BACKGROUND: Coeliac disease (CD) is a life-long food-related disorder with a global prevalence of approximately 1%. Patients with CD often experience reduced health-related quality of life that could improve with a strict adherence to a gluten-free diet (GFD). OBJECTIVES: To obtain visual analogue scale (VAS), time trade-off (TTO) and willingness-to-pay (WTP) values amongst patients with CD. METHODS: In 2020-2021, a cross-sectional online survey was conducted amongst 312 adult CD patients in Hungary. Patients completed the Gastrointestinal Symptom Rating Scale (GSRS) and evaluated their current health and three hypothetical health state vignettes defined based on dietary adherence using VAS, conventional 10-year TTO and WTP. Multivariate regressions were used to explore the effect of patients' demographic and clinical characteristics on utility and WTP values. RESULTS: Mean VAS values for current health and 'CD with strict adherence to GFD', 'CD with loose adherence to GFD' and 'CD without GFD' hypothetical health states were 79.69 ± 18.52, 85.36 ± 16.18, 62.44 ± 19.91 and 36.69 ± 25.83, respectively. Corresponding mean TTO utilities were: 0.90 ± 0.19, 0.91 ± 0.20, 0.87 ± 0.23 and 0.76 ± 0.29. Mean annual WTP values for returning to full health were: €845 ± 1077, €648 ± 1002, €862 ± 1135 and €1251 ± 1496. Older age at diagnosis, male sex, more severe gastrointestinal symptoms (GSRS) and having comorbidities were associated with lower VAS and TTO or higher WTP values for current own health (p < 0.05). CONCLUSION: This is the first study to report TTO utilities for CD health states. Strict adherence to the GFD may result in substantial health gains in symptomatic patients. Utilities and WTP results can be used to estimate benefits of GFD in cost-utility and cost-benefit analyses.

Time Trends of Environmental and Socioeconomic Risk Factors in Patients with Inflammatory Bowel Disease over 40 Years: A Population-Based Inception Cohort 1977-2020.

BACKGROUND: Data from population-based studies investigating trends in environmental factors associated with inflammatory bowel disease (IBD) is lacking. We aimed to assess long-term time trends of environmental and socioeconomic factors in IBD patients from a well-defined population-based cohort from Veszprem, Hungary. METHODS: Patients were included between 1 January 1977, and 31 December 2020. Trends of environmental and socioeconomic factors were evaluated in three periods based on the decade of diagnosis, representing different therapeutic eras: cohort-A,1977-1995; cohort-B,1996-2008 (immunomodulator era); and cohort-C, 2009-2020 (biological era). RESULTS: A total of 2240 incident patients with IBD were included (ulcerative colitis (UC) 61.2%, male 51.2%, median age at diagnosis: 35 years (IQR 29-49)). Rates of active smoking significantly decreased over time in Crohn's disease (CD): 60.2%, 49.9%, and 38.6% in cohorts A/B/C (p < 0.001). In UC, the rates were low and stable: 15.4%, 15.4%, and 14.5% in cohorts A/B/C (p = 0.981). Oral contraceptive use was more common in CD compared to UC (25.0% vs. 11.6%, p < 0.001). In UC, prevalence of appendectomy before diagnosis decreased over time: 6.4%, 5.5%, and 2.3% in cohorts A/B/C (p = 0.013). No significant changes were found in the socio-geographic characteristics of the IBD population (urban living: UC, 59.8%/64.8%/ 62.5% (p = 0.309) and CD, 62.5%/ 62.0%/ 59.0% (p = 0.636), in cohorts A/B/C). A greater percentage of patients had completed secondary school as the highest education level in later cohorts in both UC (42.9%/50.2%/51.6%, p < 0.001) and CD (49.2%/51.7%/59.5%, p = 0.002). A higher percentage of skilled workers (34.4%/36.2%/38.9%, p = 0.027) was found in UC, but not in CD (p = 0.454). CONCLUSION: The association between trends of known environmental factors and IBD is complex. Smoking has become less prevalent in CD, but no other major changes occurred in socioeconomic factors over the last four decades that could explain the sharp increase in IBD incidence.

The cost of inflammatory bowel disease in high-income settings: a Lancet Gastroenterology & Hepatology Commission.

The cost of caring for patients with inflammatory bowel disease (IBD) continues to increase worldwide. The cause is not only a steady increase in the prevalence of Crohn's disease and ulcerative colitis in both developed and newly industrialised countries, but also the chronic nature of the diseases, the need for long-term, often expensive treatments, the use of more intensive disease monitoring strategies, and the effect of the diseases on economic productivity. This Commission draws together a wide range of expertise to discuss the current costs of IBD care, the drivers of increasing costs, and how to deliver affordable care for IBD in the future. The key conclusions are that (1) increases in health-care costs must be evaluated against improved disease management and reductions in indirect costs, and (2) that overarching systems for data interoperability, registries, and big data approaches must be established for continuous assessment of effectiveness, costs, and the cost-effectiveness of care. International collaborations should be sought out to evaluate novel models of care (eg, value-based health care, including integrated health care, and participatory health-care models), as well as to improve the education and training of clinicians, patients, and policy makers.

The Optimal Management of Inflammatory Bowel Disease in Patients with Cancer.

Patients with inflammatory bowel disease (IBD) have an increased risk of cancer secondary to chronic inflammation and long-term use of immunosuppressive therapy. With the aging IBD population, the prevalence of cancer in IBD patients is increasing. As a result, there is increasing concern about the impact of IBD therapy on cancer risk and survival, as well as the effects of cancer therapies on the disease course of IBD. Managing IBD in patients with current or previous cancer is challenging since clinical guidelines are based mainly on expert consensus. Evidence is rare and mainly available from registries or observational studies. In contrast, excluding patients with previous/or active cancer from clinical trials and short-term follow-up can lead to an underestimation of the cancer or cancer recurrence risk of approved medications. The present narrative review aims to summarize the current evidence and provide practical guidance on the management of IBD patients with cancer.

Impact of biologic therapies and small molecules on the risk of major adverse cardiovascular events in patients with inflammatory bowel diseases: systematic review and meta-analysis of randomized controlled trials.

INTRODUCTION: The aim of this study is to estimate the risk of major adverse cardiovascular events (MACEs) in adult patients with inflammatory bowel disease (IBD) treated with biologic therapies and small molecules. METHODS: Databases were searched up to July 2022 to identify eligible studies that assessed the risk of MACEs in patients (age≥18 years) with IBD treated with biologic therapies and small molecules. Primary outcome was the rate of MACEs observed in patients receiving biologic or small molecules therapies during induction and maintenance phases of RCTs. RESULTS: In total 64 studies were included in the analysis. 22 RCTs involving 12,196 patients with Crohn's disease (CD) were included and 32 RCTs involving 22,007 patients with ulcerative colitis (UC). In patients with CD, risk of MACE was not higher than placebo during induction or maintenance phases, infliximab (OR 0.63, 95% CI 0.07-6.14) and ustekinumab (OR 0.50, 95% CI 0.03-8.04). In patients with UC, risk of MACE was not higher than placebo, tofacitinib (OR 1.30, 95% CI 0.15-11.21) and upadcitinib (OR 0.50, 95% CI 0.03-7.97) during induction or maintenance. CONCLUSION: The use of biologic therapies and small molecules among adult patients with IBD had no significant impact on the risk of MACEs during induction and maintenance period of RCTs. Real world data is warranted to assess long-term risks.

Biologic and new small molecule therapies have been shown to be effective in treating patients with moderate to severe inflammatory bowel disease (IBD), both Crohn's disease and ulcerative colitis. The risk of major adverse cardiovascular events (MACE), such as heart attack or heart failure, due to taking these medications in patients with IBD is not well established. The aim of this systematic review and meta-analysis is to estimate the risk of MACE in patients with IBD on biologic or small molecule therapies during induction and maintenance phases of randomized controlled trials.

Nonalcoholic Fatty Liver Disease Increases Cardiovascular Risk in Inflammatory Bowel Diseases.

Background: Nonalcoholic fatty liver disease (NAFLD) is strongly associated with cardiovascular disease in the general population. Both conditions seem more frequent in patients with inflammatory bowel disease (IBD). We aimed to assess the effect of NAFLD and liver fibrosis on intermediate-high cardiovascular risk in IBD. Methods: We prospectively included IBD patients undergoing a routine screening program for NAFLD by transient elastography (TE) with associated controlled attenuation parameter (CAP). NAFLD and significant liver fibrosis were defined as CAP ≥275 dB m-1 and liver stiffness measurement by TE ≥8 kPa, respectively. Cardiovascular risk was assessed with the atherosclerotic cardiovascular disease (ASCVD) risk estimator and categorized as low if <5%, borderline if 5%-7.4%, intermediate if 7.5%-19.9%, and high if ≥20% or if previous cardiovascular event. Predictors of intermediate-high cardiovascular risk were investigated by multivariable logistic regression analysis. Results: Of 405 patients with IBD included, 278 (68.6%), 23 (5.7%), 47 (11.6%), and 57 (14.1%) were categorized as at low, borderline, intermediate, and high ASCVD risk, respectively. NAFLD and significant liver fibrosis were found in 129 (31.9%) and 35 (8.6%) patients, respectively. After adjusting for disease activity, significant liver fibrosis and body mass index, predictors of intermediate-high ASCVD risk were NAFLD (adjusted odds ratio [aOR] 2.97, 95% CI, 1.56-5.68), IBD duration (aOR 1.55 per 10 years, 95% CI, 1.22-1.97), and ulcerative colitis (aOR 2.32, 95% CI, 1.35-3.98). Conclusions: Assessment of cardiovascular risk should be targeted in IBD patients with NAFLD, particularly if they have longer IBD duration and ulcerative colitis.
