AI-Summary

What this Trial Is About

This comparative observational cohort clinical study aims to investigate the necessity of premedication for allergy prevention prior to infliximab injection, and is designed to evaluate whether non-routine administration of dexamethasone before intravenous infusion of infliximab yields greater benefits than routine prophylactic medication in patients with moderate-to-severe inflammatory bowel disease (IBD). This study is designed to optimize the prophylactic strategy prior to Infliximab treatment and advocate for risk stratification-based individualized prophylaxis regimens to avoid hormonal abuse. Additionally, it will construct a risk score using biomarkers to accurately identify high-risk populations in need of prophylaxis and establish a corresponding predictive model. The study is also intended to reduce the use of unnecessary medications, shorten infusion duration and alleviate the medical burden. It is expected to provide targeted clinical support during the early stage of the disease or the course of treatment, improve the efficacy and precision of individualized treatment for patients, and reduce the physical, psychological and economic burdens caused by ineffective treatment.

  • Not currently receiving immunosuppressant therapy and no plan to start within 2 months.
  • Current glucocorticoid dose ≤10 tablets with a plan to taper off within 2 months.
  • Planned to receive first infliximab dose within 2 weeks.
Not Eligible

You will not qualify if you...

  • Relative contraindications to glucocorticoids (active tuberculosis, severe infection, gastrointestinal ulcer).
  • Current solid tumors, history of lymphoma or melanoma, or undergoing chemotherapy or radiotherapy.
  • Complications such as massive gastrointestinal hemorrhage, severe liver or kidney dysfunction, active infections, shock, intractable vomiting, severe malabsorption.
  • Psychiatric disorders or insufficient education to understand the study.
