Multimodal Profiling of Peripheral Blood Identifies Proliferating Circulating Effector CD4 T Cells as Predictors for Response to Integrin α4β7-Blocking Therapy in Inflammatory Bowel Disease.

Background & Aims: Despite the success of biological therapies in treating inflammatory bowel disease, managing patients remains challenging due to the absence of reliable predictors of therapy response.

Methods: In this study, we prospectively sampled 2 cohorts of patients with inflammatory bowel disease receiving the anti-integrin α4β7 antibody vedolizumab. Samples were subjected to mass cytometry; single-cell RNA sequencing; single-cell B and T cell receptor sequencing (BCR/TCR-seq); serum proteomics; and multiparametric flow cytometry to comprehensively assess vedolizumab-induced immunologic changes in the peripheral blood and their potential associations with treatment response.

Organ Offer Review Cards: Improving Transparency on the Kidney Transplant Waitlist.

Introduction: The 2022 National Academy of Sciences, Engineering, and Medicine report on equity in organ transplantation highlighted limited transparency and accountability for organ offer declines and recommended prioritizing patient engagement in decisions regarding organ offers. Yet, there is no guidance on how to incorporate patients in organ offers. We elected to study the experiences of patients on the waitlist and their perception of a novel Organ Offer Review Card (OORC).

Characterizing proximity and transfers of deceased organ donors to donor care units in the United States.

Some United States organ procurement organizations transfer deceased organ donors to donor care units (DCUs) for recovery procedures. We used Organ Procurement and Transplantation Network data, from April 2017 to June 2021, to describe the proximity of adult deceased donors after brain death to DCUs and understand the impact of donor service area (DSA) boundaries on transfer efficiency. Among 19 109 donors (56.

[Pregnancy and breastfeeding in Crohn's disease].

Inflammatory bowel disease (IBD) is often diagnosed in young adults. Starting a family is an important step in life and can be further complicated by Crohn's disease. Therefore, family planning should be discussed with every patient early in the disease course.

A Core Outcome Set for Inflammatory Bowel Diseases: Development and Recommendations for Implementation in Clinical Practice Through an International Multi-stakeholder Consensus Process.

Background And Aims: Standardising health outcome measurements supports delivery of care and enables data-driven learning systems and secondary data use for research. As part of the Health Outcomes Observatory [H2O] initiative, and building on existing knowledge, a core outcome set [COS] for inflammatory bowel diseases [IBD] was defined through an international modified Delphi method.

Methods: Stakeholders rated 90 variables on a 9-point importance scale twice, allowing score modification based on feedback displayed per stakeholder group.

Myenteric Plexus Immune Cell Infiltrations and Neurotransmitter Expression in Crohn's Disease and Ulcerative Colitis.

Background And Aims: Pain is a cardinal symptom in inflammatory bowel disease [IBD]. An important structure in the transduction of pain signalling is the myenteric plexus [MP]. Nevertheless, IBD-associated infiltration of the MP by immune cells lacks in-depth characterisation.

Presence of spondyloarthritis associated to higher disease activity and HLA-B27 positivity in patients with early Crohn's disease: Clinical and MRI results from a prospective inception cohort.

Objective: To determine the SpA prevalence and identify its associated factors in Crohn's disease (CD) patients receiving a systematically rheumatological and imaging assessment, including magnetic resonance imaging (MRI) of the sacroiliac joints and spine.

Methods: CD patients either naive to biologics or without them for three months prior enrollment were recruited in a subgroup of the German Spondyloarthritis Inception Cohort (GESPIC-Crohn). A structured assessment of SpA manifestations was performed by a rheumatologist, including MRI of sacroiliac joints and spine.

PuraStat in gastrointestinal bleeding: results of a prospective multicentre observational pilot study.

Background: A recently developed haemostatic peptide gel for endoscopic application has been introduced to improve the management of gastrointestinal bleeding. The aim of this pilot study was to evaluate the feasibility, safety, efficacy and indication profiles of PuraStat in a clinical setting.

Methods: In this prospective observational multicentre pilot study, patients with acute non-variceal gastrointestinal bleeding (upper and lower) were included.

Pregnancy Outcomes After Living Liver Donation: A Multi-Institutional Study.

Nearly half of living liver donors in North America are women of child-bearing age. Fetal and maternal outcomes after donation are unknown. We conducted a retrospective cohort study of female living liver donors (aged 18-50 years at donation) from 6 transplant centers.

Acute Kidney Injury in Deceased Organ Donors and Kidney Transplant Outcomes: A National Cohort Study Using a Novel Data Source.

Objective: The aim of this study was to determine graft function and survival for kidney transplants from deceased donors with acute kidney injury (AKI) that persists at the time of organ procurement.

Background: Kidneys from donors with AKI are often discarded and may provide an opportunity to selectively expand the donor pool.

Methods: Using Organ Procurement and Transplantation Network and DonorNet data, we studied adult kidney-only recipients between May 1, 2007 and December 31, 2016.

Wide Variation in the Percentage of Donation After Circulatory Death Donors Across Donor Service Areas: A Potential Target for Improvement.

Background: Substantial differences exist in the clinical characteristics of donors across the 58 donor service areas (DSAs). Organ procurement organization (OPO) performance metrics incorporate organs donated after circulatory determination of death (DCDD) donors but do not measure potential DCDD donors.

Methods: Using 2011-2016 United Network for Organ Sharing data, we examined the variability in DCDD donors/all deceased donors (%DCDD) across DSAs.

Level of Tumor Necrosis Factor Production by Stimulated Blood Mononuclear Cells Can Be Used to Predict Response of Patients With Inflammatory Bowel Diseases to Infliximab.

Background & Aims: A substantial proportion patients with inflammatory bowel disease (IBD) have a primary non-response to infliximab; markers are needed to identify patients most likely to respond to treatment. We investigated whether production of tumor necrosis factor (TNF) by peripheral blood mononuclear cells (PBMCs) can be used as a marker to predict response.

Methods: We performed a prospective study of 41 adults with IBD (mean age, 38 years; 21 male; 21 with Crohn's disease and 20 with ulcerative colitis) not treated with a biologic agent within the past 6 months; patients were given their first infusion of infliximab at a hospital or clinic in Berlin, Germany.

Interstitial and Granulomatous Lung Disease in Inflammatory Bowel Disease Patients.

Background: Interstitial lung [ILD] disease and granulomatous lung disease [GLD] are rare respiratory disorders that have been associated with inflammatory bowel disease [IBD]. Clinical presentation is polymorphic and aetiology is unclear.

Methods: This was an ECCO-CONFER project.

Association of Kidney Transplant Center Volume With 3-Year Clinical Outcomes.

Rationale & Objective: A robust relationship between procedure volume and clinical outcomes has been demonstrated across many surgical fields. This study assessed whether a center volume-outcome relationship exists for contemporary kidney transplantation, specifically for diabetic recipients, older recipients (aged ≥65 years), and recipients of high kidney donor profile index (KDPI ≥ 85) kidneys.

Study Design: Retrospective cohort study.

Evolving swaps in transplantation: global exchange, vouchers, liver, and trans-organ paired exchange.

Purpose Of Review: With the ongoing organ shortage, several mechanisms to facilitate organ exchanges and expand the scope of living kidney or liver donation have been proposed. Although each addresses at least one barrier to transplantation, these innovative programs raise important ethical, logistical, and regulatory considerations.

Recent Findings: This review addresses four recent proposals to expand living donor transplantation.

[Inflammatory bowel disease: cardinal signs and their diagnostics].
