简要总结
The purpose of this study is to improve the investigators understanding of the relationship between Crohn's disease and blood levels of the drug infliximab (Remicade). The investigators want to determine whether measuring drug levels can be helpful in understanding how patients respond to this treatment.
详细描述
The efficacy of infliximab to maintain remission in Crohn's disease has been confirmed by randomized, controlled trials, however the utility of serum infliximab and ATI titers is less clearly described in the clinical practice setting to manage dose and interval levels.
The primary objective of this study is to evaluate the clinical responsiveness of active (HBI >10) Crohn's disease to infliximab as it relates to serum infliximab levels. Though the assay for an infliximab level is commercially available, current dosing practices rely on the assessment of clinical data (laboratory data, symptoms, colonoscopy, etc). In order to understand this relationship, serum infliximab and ATI titers will be collected over the course of 8 (approximately 1 year) infusions. The results of these levels will be retrospectively correlated to the patient's clinical response to treatment.
The secondary objective is to identify predictors of poor response to infliximab by evaluating the efficacy of a dose escalation strategy in patients classified as primary or secondary non-responders.
Understanding the association of serum infliximab levels to disease response may be a useful objective tool to optimize and individualize dosing amount and frequency especially in patients with incomplete or loss of response to therapy.

研究组 & 干预措施
Remicade
Subjects will begin with receiving infliximab at 5 mg/kg for the first visits. If there is no response to treatment, or flare at any visit (beginning at visit #3), infliximab dose or dosing frequency will be increased in a gradual fashion, up to a maximum of 15 mg/kg every 6 weeks, until response is achieved.
干预措施: Remicade (Drug)
