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.

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

Infliximab was measured using 2 POC infliximab assays, Quantum Blue (POC IFX/QB) and Rida Quick (POC IFX/RQ Whiskers boxplot (5th–95th centile) representing the C-reactive protein concentration (mg/L) in samples with an infliximab (IFX) trough concentration above or below the threshold of 3 μg/mL, both for antibody to IFX (ATI) negative (<3.13 U/mL) and ATI positive (≥3.13 U/mL) samples. Overall median CRP was 1.8 mg/L (IQR, 0.7–4.8 mg/L) and median infliximab TC was 4.6 μg/mL (IQR, 2.4–7.3 μg/mL). 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.

SPECIAL INSTRUCTIONS. Trough level recommended (immediately before the next dose is due). 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. The measurement of antibodies to include the measurement of serum drug concentrations (trough levels) to adalimumab (Humira), infliximab (Remicade), REMICADE®, a prescription biologic for treatment of gastroenterological, reactions have included anaphylaxis, hypotension, and serum sickness). Similar to therapeutic drug monitoring (TDM) for. 6-mercaptopurine (6MP) metabolite concentrations, regular monitoring of IFX serum concentrations is predicted 10 Aug 2020 Available data suggests that for IBD patients taking Remicade® (infliximab), the lowest level of medication present in the body (trough serum 25 Feb 2016 Serum concentrations of IFX may vary among equally dosed patients which can ultimately affect patient outcomes. Suboptimal levels of IFX have ARD Pharma - Offering Infliximab Powder For Concentrate For Solution For Infusion, Packaging Type: Vial at Rs 32000/unit in Nagpur, Maharashtra. Read about Infliximab is a common treatment for people with Crohn's Disease and Ulcerative Colitis.

Infliximab serum concentrations are associated with improved treatment outcomes in IBD patients. The use of capillary blood on Whatman® paper has been clinically validated for the measurement of therapeutic monoclonal antibody adalimumab.

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.

Subjects and methods. s-IFX trough levels were Serum IFX trough concentration and anti-drug antibody (ADA) concentrations were measured. Patients were grouped by TDM results: group 1, low IFX/high ADA 2 Apr 2019 Eighty percent of all patients had IFX levels above the therapeutic concentration ( 6-10 μg/mL).

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.

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).

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.

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.
