Likewise, no difference in immunogenicity, as measured by concentrations of anti-drug antibodies, was noted before and after switching. 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.

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.

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. We identified that a serum infliximab trough concentration range of 10–15 μg/mL was associated Infliximab, an IgG1 monoclonal antibody (mab), has large inter-individual serum concentration variability.

Serum infliximab levels were measured using an enzyme-linked immunosorbent assay.

The objective was to determine the extent of the association of baseline albumin concentration and infliximab disposition in patient with ulcerative colitis.

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.

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. 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).
