We identified that a serum infliximab trough concentration range of 10–15 μg/mL was associated

2019-10-03 · Serum infliximab (IFX) concentration: 1.0 μg/mL Antibodies to infliximab (ATI) concentration: 3.1 U/mL. Comments: A lower cost option for testing is Higher serum concentrations of infliximab are associated with clinical response, mucosal healing, and clinical remission in adults with moderate to severe ulcerative colitis, according to post hoc analyses of data from the Active Ulcerative Colitis Trials, ACT-1 and ACT-2. Background and aim Objective and more rigorous therapeutic outcomes are emerging as novel targets in Crohn's disease (CD). We investigated the association between maintenance serum infliximab trough concentrations and biochemical, endoscopic, or histologic remission in CD. Methods This retrospective multicenter study involved consecutive CD patients treated with infliximab who had a serum C The intensity of emitted light is measured and correlated to a set of standards with known concentrations of ATI by means of a 4-point logistics curve fitting method.(Willrich M, Balsanek J, Ladwig P, et al: A-374 Antibodies-to-Infliximab: Assay Development and Correlation with Infliximab Concentrations in Serum Samples of Treated Patients. DBS IFX concentrations showed high correlation with serum IFX concentrations (Spearman correlation: ≥0.965), without bias. Passing‐Bablok regression for IFX concentrations in DBS from home sampling also showed no bias (intercept: 1.02 mg L −1 (95% CI −1.77–2.04 mg L −1 ), slope: 0.82 (95% CI 0.63–1.40)), with reasonable correlation (Spearman correlation: 0.671).

High concentrations of infliximab during treatment initiation reduce the development of ATI, and the absence of ATI may be associated with prolonged maintenance of infliximab. Thus, trough serum infliximab concentration should be monitored early in patients with rheumatic diseases. We aimed to study the relationship between trough serum concentrations of infliximab (CIFX) and the risk of a first infectious episode (IE) in treated patients. Methods: We retrospectively included all patients who started infliximab treatment in our department. Patients were followed-up based on recommended infliximab infusions schedule.

At week 0, the median serum concentrations of the 1 hour–postinfusion samples were 68.6 μg/ml and 219.1 μg/ml for subjects receiving 3 mg/kg and 10 mg/kg infliximab, respectively, every 8 weeks (Table 1 ). The trough concentration (TC) of infliximab, which is the drug concentration in serum just before the next infusion, has been linked to biological, clinical, and endoscopic outcomes. 1, 2, 3 Recently, several prospective trials have identified concentration-based dosing as a cost-effective alternative to clinically based dosing. 4, 5 However are (POC) devices for quantification of serum infliximab concentration with 2 validated ELISA assays in children with IBD. Methods: We studied 32 serum samples from 19 children with IBD treated with infliximab.

high serum interferon activity and antiphospholipid syndrome in systemic protein biomarkers provides prediction of anti-TNF response in rheumatoid association study of total serum immunoglobulin E concentration.

s-IFX trough levels were 18 Feb 2021 Overall, participants with a mean infliximab trough concentration as infliximab and adalimumab, that high serum drug concentrations are 19 Sep 2019 Methods: Serum Vit-D and zinc levels as well as Infliximab (IFX) and as the serum drug trough concentration (TC) in anti-TNF-α treated IBD Serum infliximab (IFX) concentration and antibodies (ATI) in pediatric (TDM, measurement of serum drug and ATI levels) may avoid treatment failure. 22 Mar 2021 In the absence of anti-infliximab antibodies, the infliximab drug level typically reflects the total infliximab concentration in serum. In the presence Objective. To study serum infliximab (s-IFX) levels in pediatric patients with inflammatory bowel disease (IBD).
