However, evidence on the role of exclusive enteral nutrition (EEN) in TH remains limited. This study aimed to evaluate the efficacy of biologics combined with 16-week EEN in achieving early TH and improving clinical outcomes. This real-world, multicenter retrospective study analyzed medical records of patients with moderate-to-severe CD from 2016 to 2024. Patients received either biologics with concomitant 16-week EEN (BioEEN) or biologics alone (Bio). Clinical and endoscopic outcomes, including transmural healing, were assessed at week 16, year 1, and year 2. At baseline, demographic and clinical characteristics were comparable between the two groups. The BioEEN group demonstrated superior clinical response rates compared to the Bio group (95.1% vs. 70.6% at week 16; P < 0.001), with sustained benefits at week 52 (87.8% vs. 59.5%; P < 0.001). Subgroup analysis revealed higher endoscopic response, mucosal healing, and TH rates in both colorectal and ileal segments at weeks 16 and 52 in the BioEEN group. Additionally, the BioEEN group had significantly lower rates of surgery, escalated treatment, bowel damage progression, and disease relapse at 1 and 2 years. Regression analysis identified the 16-week EEN as the sole protective factor for early transmural healing and improved long-term outcomes. Combined treatment of biologics and 16-week EEN promotes early transmural healing, thereby enhancing long-term clinical outcomes in CD patients.</p>","PeriodicalId":153,"journal":{"name":"Clinical Pharmacology & Therapeutics","volume":" ","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144937075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal of this study was to evaluate the intrinsic anti-epileptic and sedative properties of CBD. A randomized, double-blind, placebo-controlled, 3-way crossover trial was conducted in 25 healthy males. On each visit, single doses of 30 mg CBD, 700 mg CBD, or placebo were administered orally. The effects of CBD on cortical excitability were measured using transcranial magnetic stimulation (TMS) combined with electromyography (EMG) and electroencephalography (EEG). Sedative properties were assessed using a validated CNS test battery. Pharmacokinetic sampling was performed. Data were analyzed using a mixed-effects model. CBD did not have significant effects on single pulse and paired pulse TMS-EMG parameters, compared to placebo. Some significant clusters were seen on paired pulse TMS-EEG at 3 hours post-dose for 30 mg CBD, and at 3 and 5 hours post-dose for 700 mg CBD. CBD did not have significant effects on any tests assessing its sedative properties.
