Ordás I, Feagan BG, Sandborn WJ. 2019-05-08 PROMETHEUS® Anser® IFX measures both serum infliximab levels and antibodies to infliximab – valuable information to help guide your treatment decisions for patients who lose response to infliximab. 2017-03-07 · The mean s-IFX trough level was 5.2 µg/mL. The mean trough s-IFX level was significantly higher in the samples taken during remission (7.2 µg/mL) compared to active disease (4.5 µg/mL, p < 0.05). The trough s-IFX levels correlated with ESR, CRP, and albumin. The present study and evidence from previous studies clearly show that it is time to incorporate the measurement of trough serum levels of infliximab in our treatment monitoring strategy in both Crohn’s disease and UC. Measuring trough levels at weeks 10 and 26 should be very useful to guide our treatment. Receiver operation curve revealed that the optimal cutoff value of IFX trough levels for identifying normal laboratory markers was 0.6 μg/ml for CRP, 1.0 μg/ml for serum albumin and 1.1 μg/ml for fecal calprotectin. Background: There is some evidence in adults that higher serum infliximab (IFX) levels are needed to adequately treat fistulizing perianal Crohn's disease (CD).

Relationship between serum trough infliximab levels, pretreatment C reactive protein levels, and clinical response to infliximab treatment in patients with rheumatoid arthritis. Ann Rheum Dis. 2005; 64 : 704-707 Similarly, Davidov et al.

The aim of this study was to identify genetic variants associated with trough serum anti‐TNF levels and whether these variants are differential markers for infliximab and adalimumab. Methods. We included 154 children (age < 18 years) from 17 hospitals who had been diagnosed with IBD and actively treated with infliximab or adalimumab.

Serum trough consecutive infliximab serum trough levels and anti-infliximab antibodies in patients with stable DAS28 and treatment was analysed with Spearman correlation and kappa-analysis. Results: 147 patients with a mean disease duration of 11 years (sd7) and DAS28 of 3.5 (sd1.3) at baseline were CT-P13 is a biosimilar drug of reference infliximab and is approved in some countries for use in some indications for which reference infliximab is ap… Changes in the trough level of infliximab (TLI) from week 14 to week 54. The mean infliximab (IFX) trough concentrations at week 54 in the TLI(14) ≥ 3 (trough level of IFX at week 14 > 3 μg/mL) group and TLI(14) < 3 (trough level of IFX at week 14 < 3 μg/mL) group were 6.5 and 1.0 μg/mL, respectively. ATI = antibodies to infliximab. There is a significant association between serum infliximab levels and rates of fistula healing. Achieving infliximab levels ≥10.1 mcg/mL in patients with Crohn's disease and perianal fistulas may improve outcomes as part of a treat‐to‐target strategy. Background and Aims: Antibodies to infliximab reduce serum infliximab with loss of clinical benefit, but undetectable trough serum concentrations of infliximab may occur without antibody formation.

Methods. We included 154 children (age < 18 years) from 17 hospitals who had been diagnosed with IBD and actively treated with infliximab or adalimumab. In the proactive monitoring group, serum trough levels of infliximab guided dose change to achieve target drug levels according to the algorithm presented in table 3. Reactive testing was done in both groups if the disease lost response or there was a concern for side effects because of antibody formation. 2021-03-22 · In the presence of anti-infliximab antibodies, the infliximab drug level typically reflects the antibody-unbound fraction of infliximab concentration in serum. The presence of infliximab drug, even at concentrations well above target treatment levels (>50 ug/mL), does not interfere with the anti-infliximab antibody detection.
