Mean serum infliximab levels were 5.46 +/- 5.62 microg/ml 2 weeks after the final administration of infliximab, 2.02 +/- 1.66 microg/ml just before the operation, and 1.48 +/- 1.31 microg/ml 1 day post operation. Moreover, the mean serum level in an autologous blood bag sampled just before AB donation was 5.02 +/- 4.79 microg/ml.

Design In an observational 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. 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.

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.

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. 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.

Serum infliximab concentration

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. • In the presence of anti-infliximab antibodies, the infliximab drug level reflects the antibody-unbound fraction of infliximab concentration in serum.

s-IFX trough levels were  Serum IFX trough concentration and anti-drug antibody (ADA) concentrations were measured.

2020-07-15 · Abstract. 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. Compared with labor‐intensive conventional software for pharmacokinetic (PK) modeling (eg, NONMEM) dashboards are easy‐to‐use programs

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.
