Abstract

BACKGROUND: Patients with chronic immune-mediated disorders (IMIDs), including inflammatory bowel disease (IBD), are at increased risk of cardiovascular disease. While advanced therapies show cardioprotective effects in other IMIDs, their impact on major adverse cardiovascular events (MACE) in IBD remains unclear. We conducted a meta-analysis of randomized controlled trials (RCTs) and observational studies evaluating MACE risk with advanced therapies in IBD. METHODS: Systematic search of PubMed, Embase, and Cochrane Central Register of Controlled Trials identified 43 studies (36 RCTs, including 9 long-term follow-up (LTF) studies, and 7 observational studies) published between 2002 and 2024. Primary analyses estimated odds ratios (OR) for MACE comparing advanced therapy to placebo, with secondary analyses stratifying studies by drug class and length of follow-up. Sensitivity analyses were conducted using alternative methods to account for zero-event data. RESULTS: Placebo-controlled RCTs showed a nonsignificant trend toward reduced MACE risk (OR 0.60; 95% CI 0.24-1.51), with similar findings across sensitivity analyses accounting for sparse and zero-event data. Class-specific trends suggested lower MACE risk with IL-12/IL-23 inhibitors (OR 0.35; 95% CI 0.05-2.21), JAK inhibitors (OR 0.57; 95% CI 0.16-2.06), and a potential increase with Anti-TNF agents (OR: 3.04; 95% CI 0.31-29.47), though none reached statistical significance. LTF studies showed consistent findings. Observational studies suggested lower MACE risk with Anti-TNF therapies (OR 0.29; 95% CI 0.21-0.40), but not with IL-12/IL-23 (OR 4.41; 95% CI 0.49-39.28) or JAK inhibitors (OR 1.57; 95% CI 0.86-2.84). CONCLUSION: Advanced therapies did not demonstrate a clear increase or decrease in cardiovascular risk in IBD. The discrepancies between RCTs and observational studies underscore the urgent need for rigorous-designed observational research with long-term follow-up to evaluate the real-world impact of advanced therapies on MACE risk.

Positive conversion of latent tuberculosis screening in patients with inflammatory bowel disease on antitumor necrosis factor alpha drugs: a systematic review and meta-analysis.

Inflammatory bowel disease (IBD) patients undergoing antitumor necrosis factor-alpha (anti-TNF) therapy are at increased risk of developing tuberculosis (TB), making screening before anti-TNF initiation mandatory. Repeated screening during treatment is not yet recommended because of a lack of studies to support this practice. We aimed to determine the proportion of patients who develop latent TB during anti-TNF therapy. We systematically searched studies from MEDLINE, Embase, and Lilacs, and performed a single-arm meta-analysis investigating the positive conversion rate in IBD patients under anti-TNF therapy with previous negative TB screening. We calculated the combined proportion with 95% confidence interval, using the random-effects model. A P value less than 0.05 was considered statistically significant for subgroup differences. We included 13 studies from nine countries with 1153 patients. The overall positive conversion rate was 9.20%. Portugal had 18.01% of positive conversion, Spain 4.51%, and the USA 1.11%. Tests for subgroup differences were statistically significant for subgroup analysis by country and consistency of test used (performig same test as baseline). Subgroup analyses by continent, study design, or specific test (tuberculin skin test or interferon-gamma release assay) showed no statistical difference. Meta-regression analysis showed a significant positive association between positive conversion and TB incidence. In conclusion, IBD patients on anti-TNF therapy can have a positive conversion rate of 9.20%. Higher conversion rates were seen in European and Asian studies compared with those in the Americas (particularly the USA). TB prevention strategies should, therefore, be individualized and based on geographic location and risk factors.

Randomized Trial of Intensive Nurse-Led Follow‑Up Versus Standard Care in Inflammatory Bowel Disease.

BACKGROUND: &#xa0;Nurses play a key role in inflammatory bowel disease (IBD) management. This randomized controlled trial evaluated intensive nurse-led program in patients with IBD starting advanced therapy. METHODS: &#xa0;Patients were randomized (1:1) to intensive nurse follow&#x2011;up (Arm&#xa0;A) or standard care (Arm&#xa0;B). Both arms received baseline nurse education; Arm A additionally had scheduled nurse calls and visits. Primary outcome was reduction in IBD&#x2011;Disk score in W12. Secondary outcomes were W52 reduction, robust response (>&#x2009;20-point improvement), and IBD-Disk remission (score&#x2009;<&#x2009;40). RESULTS: Overall, 98 patients were randomized (Arm&#xa0;A:&#xa0;n&#x2009;=&#x2009;50; Arm&#xa0;B:&#xa0;n&#x2009;=&#x2009;48) with similar baseline characteristics. Mean baseline IBD&#x2011;Disk scores were 49.2&#x2009;&#xb1;&#x2009;20.7 in Arm&#xa0;A and 42.0&#x2009;&#xb1;&#x2009;19.8 in Arm&#xa0;B (p&#x2009;=&#x2009;0.07). At W12, both groups improved, with greater IBD-Disk reductions in Arm A (16.1&#x2009;&#xb1;&#x2009;22.9 vs. 10.1&#x2009;&#xb1;&#x2009;20.1, p&#x2009;=&#x2009;0.09). At W52, improvement was greater in Arm&#xa0;A (18.4&#x2009;&#xb1;&#x2009;20.7 vs 9.4&#x2009;&#xb1;&#x2009;17.8; p&#x2009;=&#x2009;0.08). More patients achieved robust response in Arm A (49% vs 21%, p&#x2009;=&#x2009;0.013) at W12. By W52, IBD-Disk remission was achieved by 22/25 (88%) patients in Arm A vs 18/28 (64%) in Arm B (p&#x2009;=&#x2009;0.045). CONCLUSIONS: &#xa0;In this pilot randomized trial, intensive nurse-led follow-up did not significantly improve IBD-Disk at week 12, yet favorable trends of functional outcomes were observed. Intensive nurse&#x2011;led follow&#x2011;up program may improve quality of life in patients with IBD. These findings support the integration of specialist IBD nurses to improve patient&#x2011;centered outcomes.

Pairwise Comparative Safety and Effectiveness of Anti-TNF Blockers, Vedolizumab, and Ustekinumab During Pregnancy: A Systematic Review and Meta-Analysis.

PURPOSE: Biologic therapies, including tumor necrosis factor (TNF) blockers, vedolizumab (VDZ), and ustekinumab (UST), are generally considered safe during pregnancy in patients with inflammatory bowel disease (IBD), though comparative data remain limited. This meta-analysis examines their safety and effectiveness. METHODS: A systematic search of MEDLINE, EMBASE, CINAHL, Cochrane, and Web of Science was conducted through July 2025. Eligible studies reported maternal or neonatal outcomes in pregnant IBD patients treated with biologics. Studies were pooled using a random-effects model to calculate risk ratios (RRs) with 95% confidence intervals. Heterogeneity was assessed using I2. Primary outcomes were preterm birth and disease activity; secondary outcomes included pregnancy and neonatal outcomes. RESULTS: Nine observational studies (n&#x2009;=&#x2009;6,054) were included. Compared to TNF blockers, VDZ was associated with a higher risk of preterm delivery (RR&#x2009;=&#x2009;1.35, 95% CI 1.04-1.75, I2&#x2009;=&#x2009;0%) and active disease (RR&#x2009;=&#x2009;1.55, 95% CI 1.01-2.40, I2&#x2009;=&#x2009;50%). UST was associated with a higher risk of active disease (RR&#x2009;=&#x2009;1.30, 95% CI 1.06-1.60, I2&#x2009;=&#x2009;0%) and congenital anomalies (RR&#x2009;=&#x2009;2.08, 95% CI 1.30-3.32, I2&#x2009;=&#x2009;0%) compared to TNF blockers. Compared to UST, VDZ was linked to increased risks of preterm birth (RR&#x2009;=&#x2009;2.60, 95% CI 1.03-6.57, I2&#x2009;=&#x2009;0%) and low birth weight (RR&#x2009;=&#x2009;2.38, 95% CI 1.01-5.60, I2&#x2009;=&#x2009;0%). No significant differences were observed for live births, abortions, hospitalizations, or neonatal infections. CONCLUSION: TNF blockers showed a favorable safety and effectiveness profile, VDZ and UST performed broadly similar, and all three biological classes appeared compatible with safe use in pregnancy to maintain effective disease control. Observed differences reflect that VDZ and UST cohorts likely had longer disease duration, prior biologic exposure, and more active disease. The results of this meta-analysis support the continuation of biologic therapy for disease control in pregnant patients with IBD. Treatment decisions should be individualized and tailored to each patient's clinical context.
