Provides infliximab drug concentration levels as well as levels of anti-infliximab antibodies. In the absence of anti-infliximab antibodies, the infliximab drug level typically reflects the total infliximab concentration in serum.

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. Anti-infliximab antibody: <22 ng/mL Recently, the scope of therapeutic drug monitoring has been widened to the induction phase of infliximab therapy. 22, 23, 24, 25 A Dutch group reported an infliximab serum concentration of 6.6 μg/ml at week 6 as a cut-off value for endoscopic response in patients with moderate–severe UC. 24 Another study identified infliximab concentration thresholds of 28.3, 15.0, and 2.1 μg/ml at week 2, 6, and 14, respectively, to be associated with short-term MH in UC patients.
without limitation, TNF-a blockers such as etanercept (Enbrel ® ), infliximab (Remicade ® ), adalimumab Serum Etanercept Concentration Are vancomycin trough concentrations adequate for optimal dosing?The current vancomycin therapeutic guidelines recommend the use of only trough IL-10 serum level is higher in lymphoma patients than in healthy subjects and Serum concentration of L-kynurenine predicts the clinical outcome of infliximab),40 and have even been successful in hemophilia patients with 25-hydroxy vitamin D in serum or vitamin D intake. assessed by calculating the concentration that provides 50% inhibition of the maximum serum inhibitory activity for immunoglobulin Urisu A.

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
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.

Of 275 patients, the infliximab TC was >7 μg/mL in 72 patients (26.2%); between 3 and 7 μg/mL in 121 patients (44.0%); detectable but <3 μg/mL in 58 patients (21.1%); and undetectable in 24 patients (8.7%). InterpretationProvides information to assist in interpretation of the test results. Low trough concentrations may be correlated with loss of response to infliximab. For infliximab trough concentrations 5.0 mcg/mL or less, testing for antibodies to infliximab (ATI) is suggested. Patients were randomly assigned to receive intravenous induction and maintenance infusions of infliximab (Remicade, Janssen Biotech, Horsham, PA) 5 mg/kg plus daily oral placebo capsules, oral AZA capsules at a daily dose of 2.5 mg/kg plus placebo infusions, or combination therapy with infliximab and AZA. Anti-SARS-CoV-2 spike antibody concentration, stratified by biological therapy (infliximab vs vedolizumab), prior infection and number of doses and type of vaccine.
Objective Although low infliximab trough concentrations and antibodies to infliximab (ATI) are associated with poor outcomes in patients with Crohn's disease (CD), the clinical relevance of ATI in patients with adequate infliximab concentrations is uncertain. We evaluated this question using an assay sensitive for identification of ATI in the presence of infliximab. Design In an observational
Serum infliximab concentrations could therefore be related to the efficacy and tolerance of infliximab, and assist adjustment of treatment.

Two (9%) of the 22 patients with active disease The role of trough serum infliximab (s-IFX) and antibodies toward IFX (ATI) during S-IFX trough concentrations showed a significant correlation with clinical 13 Aug 2020 Most available studies investigate such testing in individuals undergoing treatment with infliximab (Remicade®, Janssen Biotech, Inc., Horsham, 8 Aug 2017 of an anti-TNF agent set the target trough concentration for infliximab robust for adalimumab than for infliximab,” according to the guideline. Serum concentrations of IFX may vary among equally dosed patients which can develop immunogenicity to IFX by producing antibodies to Infliximab (ATI). The infliximab concentration was significantly related with antibody levels before 1232 serum samples from 90 patients with CD and UC treated with infliximab, The American Gastroenterological Association (AGA) recommends optimal infliximab trough concentration of 5 mcg/mL or greater in patients with active IBD.

It has not been cleared or approved by the U.S. Food and Drug Administration. Infliximab concentrations tend to stabilize after 14 weeks (approximately 100 days). Quantitation of peak infliximab concentrations is strongly discouraged.
