Index cancers were solid organ (138; 46%), dermatologic (100; 33%) GI (34; 11%), hematologic (27; 9%), or of other types (3; 1%); most index cancers (excluding non-melanoma skin cancer) were diagnosed as Stage 1. Following the index cancer, 90 (30%) patients were not exposed to any immunosuppression, and the other 212 were exposed to immunosuppressive therapy: 142 biologic monotherapy (anti-TNF, anti-integrin, anti-IL12/23, anti-IL23; 47%), 13 anti-metabolite monotherapy (mercaptopurine, azathioprine, methotrexate; 4%), 41 biologic + anti-metabolite combination therapy (14%), and 16 exposed to small molecules (JAK inhibitors, ozanimod; 5%).

In this study we aimed to explore whether patients with quiescent IBD reporting fatigue exhibit specific systemic antibody responses, which could provide insight into immune reactivities underlying fatigue.\u0000 \u0000 \u0000 \u0000 Systemic antibody epitope repertoires were profiled in 327 patients with IBD (156 Crohn’s disease [CD]; 171 ulcerative colitis [UC]) leveraging phage-display immunoprecipitation sequencing (PhIP-Seq) against 344,000 rationally selected peptide antigens. Fatigue severity was assessed on a 10-point Likert scale, ranging from 1 (no fatigue) to 10 (highest fatigue severity). Quiescent IBD was defined as clinical (Harvey-Bradshaw Index [HBI] <5 or Simple Clinical Colitis Activity Index [SCCAI] <2.5) and biochemical remission (C-reactive protein [CRP] <5 mg/L) at time of sampling.

Among highly fatigued patients, antibody responses were primarily directed towards viral antigens, notably several antigens from Epstein-Barr virus (EBV), as well as bacterial antigens, including functional proteins from Streptococcus and Staphylococcus species. Fatigued patients with CD exhibited elevated systemic antibody responses against allergens, Staphylococcus, Pseudomonas aeruginosa, and Shigella spp. Fatigued patients with UC showed higher frequencies of antibody responses against herpes simplex virus (HSV), influenza viruses, and few responses against allergens and Streptococcus bacteria.

Primary outcomes were assessed using the modified Pouchitis Disease Activity Index (mPDAI). mPDAI response was defined as a reduction from baseline of ≥2 points, while mPDAI remission was defined as mPDAI response in addition to mPDAI score ≤4.\u0000 \u0000 \u0000 \u0000 Therapeutic interventions among 51 patients included CDED (n=10), vedolizumab (n=21), ustekinumab (n=7) and adalimumab (n=13) [Table 1].\u0000 At 12 and 26 weeks, overall mPDAI response rates were 52% and 48%, respectively, with no significant difference between groups. At 52 weeks, mPDAI response rates were significantly higher for ustekinumab and vedolizumab (60% and 55%, respectively) compared with adalimumab and CDED (27.3% and 0%, respectively), p=0.043. Fecal calprotectin reduction at week-26 was greatest for ustekinumab (93%), followed by vedolizumab (73%), adalimumab (55%), and CDED (-13%), p=0.003.\u0000 Treatment persistence over 150 weeks was significantly higher for ustekinumab (100%) compared with adalimumab (46%), vedolizumab (33%), and CDED (20%), p<0.001 [Figure 1]. The predominant cause for treatment discontinuation was secondary loss of response (50%), followed by primary non-response and surgical complications (14.7% each), poor compliance (11.8%), side-effects (5.9%), and development of antibodies (2.9%).\u0000 Patients without prior biologic or immunomodulator treatment for pouchitis had significantly higher mPDAI response rates at 12 weeks (90%, p=0.016 and 73.3%, p=0.03, respectively). Patients with surgical pouch complications showed a trend towards lower mPDAI-defined response rates at 12 weeks (25% vs. 64.7%; p = 0.064).\u0000 \u0000 \u0000 \u0000 Ustekinumab and vedolizumab demonstrate higher likelihood of maintaining long-term clinical and endoscopic response, along with greater reduction in fecal calprotectin compared with adalimumab and CDED.

Incident patients who received CDED coupled with PEN in the setting of the loss of response to other maintenance therapies from January 1st, 2020 to June 30th 2023 were included. Clinical remission at the end of each phase was defined by a weighted Pediatric Crohn’s Disease Activity Index (wPCDAI) below 12.5. Biochemical remission was defined by a c-reactive protein (CRP) lower than 0.5 mg/dL. A FC lower than 150 mg/kg was used as a surrogate of mucosal improvement (MI).\u0000 \u0000 \u0000 \u0000 25 patients (52% males) met inclusion criteria and were included in the analysis.

The most frequent disease location was ileocolonic (64%), 3 (12%) patients had isolated colonic involvement. 9 (36%) patients had stricturing/penetrating phenotype. 16 patients (68%) were being treated with an anti-TNF-alpha agent, whereas 5 (20%) patients were receiving ustekinumab (Table 1). wPCDAI, CRP and FC significantly decreased after the firs 8 weeks of treatment (22.5 vs 2.5, 1 vs 0.2, 640 vs 360, p<0.001, p=0.019 and p=0.007, respectively). At the end of phase I, 19/25 (76%) of the patients achieved clinical remission, 15 (60%) patients had CRP levels within normal range and 7 (28%) of them had normalized FC. 18/25 patients (72%) had received Exclusive Enteral Nutrition (EEN) for the induction of remission at diagnosis. Patients who achieved clinical remission with the EEN course (i.e.: a wPCDAI of < 12.5 after a complete course of EEN) were more likely to achieve clinical remission when receiving CDED + PEN (11/13 vs 1/5, p=0.022).\u0000 \u0000 \u0000 \u0000 CDED coupled with PEN is a valid treatment strategy in the setting of secondary loss of response to maintenance treatments in children with CD.
