The Relationship between Ocular Vascular Changes and the Levels of Malondialdehyde and Vascular Endothelial Growth Factor in Patients with Inflammatory Bowel Disease.

The Relationship between Ocular Vascular Changes and the Levels of Malondialdehyde and Vascular Endothelial Growth Factor in Patients with Inflammatory Bowel Disease. Ocul Immunol Inflamm. 2020 Apr 07;:1-5 Authors: Sengul Samanci N, Poturoglu S, Samanci C, Ustabasioglu FE, Koldas M, Duman AE, Ormeci AC Abstract Background: We evaluated ocular hemodynamic changes, malondialdehyde(MDA) and vascular endothelial growth factor (VEGF) levels in patients with IBD.Methods: We used ocular color Doppler ultrasonography to analyze 56 eyes with Crohn's disease (CD), 62 eyes with ulcerative colitis (UC), 68 eyes of healthy volunteers. We measured peak systolic velocity (PSV),end-diastolic velocity (EDV),and the resistivity index (RI) of ophthalmic artery (OA) and central retinal artery (CRA). MDA and VEGF levels were measured in the plasma samples.Results: MDA levels were significantly higher in both UC and CD patients, whereas VEGF levels were only higher in the CD group (p = .003,p

RNAseq was performed to unbiasedly assess the transcriptional responses to these stimuli and revealed highly divergent macrophage transcriptional programs in response to non-IBD compared to IBD VLP.

Conclusion: Lnc-ITSN1-2 correlates with increased disease risk, activity, and inflammatory cytokines of IBD, and promotes IBD CD4+ T cell activation, proliferation, and Th1/Th17 cell differentiation by serving as a competing endogenous RNA for IL-23R via sponging miR-125a.

CONCLUSION: Baseline characteristics and outcomes of patients with IBD-IgAV are similar to those with IgAV without IBD. Development of IgAV is not limited to patients with clinically active IBD. Whether TNFi use is related to the pathogenesis of IgAV in some patients with IBD remains unclear. Further research into pathophysiological connections between IBD and IgAV is needed.

The peroxisome proliferator-activated receptors (PPARs) are a group of nuclear receptor proteins that promote ligand-dependent transcription of target genes that regulate energy production, lipid metabolism, and inflammation. The PPAR superfamily comprises three subtypes, PPARα, PPARγ, and PPARβ/δ, with differential tissue distributions. In addition to their different roles in the regulation of energy balance and carbohydrate and lipid metabolism, an emerging function of PPARs includes normal homeostasis of intestinal tissue. PPARα activation represses NF-κB signaling, which decreases the...

CONCLUSION: Our meta-analyses have indicated the significant associations between SNPs (IRF5 rs4728142, PTGER4 rs4613763, and IL12B rs6887695) and CD/UC/IBD. PMID: 32464244 [PubMed - as supplied by publisher]

Conclusions: In this real-life prospective cohort using dose optimization, thiopurines were safe and effective in 21% of CD and 27% of UC patients, including normalization of C-reactive protein and erythrocyte sedimentation rate. Thiopurines remain a viable option in the treatment algorithm of mild-moderate pediatric IBD, especially in girls whose risk for lymphoma is lower.

DiscussionThe etrolizumab phase  3 clinical program is the largest and most comprehensive in inflammatory bowel disease, enrolling more than 3000 patients. The program explores both induction and maintenance regimens. HIBISCUS I and II and GARDENIA are among the first head-to-head trials in UC against an anti-TNF and are the fir st registrational trials making that comparison. This program will also help address unanswered clinical questions on evaluation of treatment effects and treatment selection across a range of patients with varying treatment histories using an extensive repository of patient samples and da...

Authors: D'Amico F, Fiorino G, Furfaro F, Allocca M, Roda G, Loy L, Zilli A, Solitano V, Peyrin-Biroulet L, Danese S Abstract Introduction: Several biological drugs and a new small molecule are available for the treatment of Crohn's disease and ulcerative colitis. However, to date, no reliable predictors of response to treatment have yet been identified.Areas covered: We focused on studies evaluating the therapeutic management of patients with chronic inflammatory bowel diseases in order to identify any predictive factors of response to drugs and to guide therapeutic decisions based on patient and disease character...

ConclusionsA substantial percentage of biologic-na ïve IBD patients suffers from active disease/steroid dependency. The majority receives a monotherapy with systemic CS. Referral to gastroenterologists for treatment optimization is recommended, also because active disease/steroid dependency is associated with increased HCRU/cost.

This study aims to evaluate the thera peutic alternatives that would allow for the appropriate management of patients with both SpA and IBD.Key Points• Collaboration between gastroenterologists and rheumatologists is recommended to improve the management of patients with spondyloarthritis (SpA) and inflammatory bowel disease (IBD).• When treating SpA occurring simultaneously with IBD, it would be appropriate to give priority to the active disease.• Considering its well-proven efficacy in both conditions, anti-tumor necrosis factor (TNF) therapy remains the corner stone in the treatment of these patients...
