Outcomes of Patients With Inflammatory Bowel Disease Receiving Proactive Compared With Reactive Monitoring of Serum Concentrations of Infliximab.

However, proactive monitoring of anti-TNF concentrations with titration to a and recent studies suggest a correlation between serum drug concentrations and 

The American Gastroenterological Association (AGA) recommends optimal infliximab trough concentration of 5 mcg/mL or greater in patients with active IBD. Data from separate clinical studies suggest an optimal infliximab trough concentration of greater than 3.8 or 6-10 mcg/mL. 2021-03-29 · At visit 2, one of these four options was again selected, but with consideration of the trough serum infliximab concentration measured at visit 1 as well as disease activity control. In total, the Serum infliximab concentrations could therefore be related to the efficacy and tolerance of infliximab, and assist adjustment of treatment. The aim of this systematic review was to assess the value of measuring serum infliximab concentrations in psoriatic patients.

Qualitative analysis was also performed to evaluate whether POC assays would correctly classify infliximab serum according to a target window (between 3 and 7 μg/mL). RESULTS: ICC was 0.82 and 0.87 for POC IFX/QB and POC IFX/RQ with the primary reference ELISA assay, respectively; ICC between the 2 ELISA assays was 0.87. The serum infliximab concentration threshold of 5.1 μg/mL at week 14 is consistent with that defined by ROC analysis for week 30 (3.7 μg/mL) when consideration is given to the fact that the concentration at week 14 theoretically is expected to be slightly higher than the concentration at week 30 because only 8 weeks (1 maintenance dose interval) have elapsed before the week-14 sampling, after the 3 induction doses at weeks 0, 2, and 6. We identified that a serum infliximab trough concentration range of 10–15 μg/mL was associated with endoscopic or histologic remission in CD with rates of >70% or 60%, respectively. The finding that even higher infliximab concentrations are linked to more rigorous outcome measures is in line with the results of 2 other recent studies. Infliximab drug level: <0.4 µg/mL • Result ≥0.4 µg/mL indicates detection of infliximab.

2020-07-15 · Abstract.

Infliximab, an IgG1 monoclonal antibody (mab), has large inter-individual serum concentration variability. The objective was to determine the extent of the association of baseline albumin concentration and infliximab disposition in patient with ulcerative colitis.

Human Anti-Chimeric Ab (HACA): Result ≥22 ng/mL indicates detection of anti-infliximab antibodies. 2018-04-15 · The authors concluded that measurement of ATI and infliximab concentration had a clinically useful effect on patient management. The strategy of increasing infliximab dose in patients with ATI was ineffective whereas in patients with subtherapeutic infliximab concentrations this strategy was a good alternative to changing to another anti-TNF agent. REMICADE, median infliximab serum concentrations ranged from aimed at measuring serum infliximab trough levels during REMICADE treatment and.

We sought to compare 2 point-of-care (POC) devices for quantification of serum infliximab concentration with 2 validated ELISA assays in children with IBD.

Serum concentrations were also obtained prior to dosing and one hour post-dosing. Infliximab levels were measured by ELISA (lowest detectable level = 0.1 μg/ml). 2017-03-31 · Serum infliximab (IFX) and antibody-to-infliximab (ATI) levels are objective parameters that may help in the therapeutic decisions during maintenance biological therapy.

Results: At week 54, 26% of the subjects receiving 3 mg/kg infliximab every 8 weeks had undetectable trough serum levels of infliximab, a significantly greater proportion than in the other 3 treatment groups (P < 0.001). Although the relationship between exposure to infliximab and response varied among patients, approximate serum concentrations of 41 μg/mL infliximab at week 8 of induction therapy and 3.7 μg/mL at steady-state during maintenance therapy produced optimal outcomes in patients.

The strategy of increasing infliximab dose in patients with ATI was ineffective whereas in patients with subtherapeutic infliximab concentrations this strategy was a good alternative to changing to another anti-TNF agent.

Despite a robust exposure–response relationship of infliximab in inflammatory bowel disease (IBD), attempts to adjust dosing to individually predicted serum concentrations of infliximab (SICs) are lacking.
