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.

Infliximab is a common treatment for people with Crohn's Disease and Ulcerative Colitis. Our information can help you to decide if this treatment is right for you. It 

High concentrations of infliximab during treatment initiation reduce the development of ATI, and the absence of ATI may be associated with prolonged maintenance of infliximab. 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.

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. The ATI assay has been verified to analyze infliximab and infliximab-dyyb (Inflectra, Pfizer Inc) with no analytical differences between the 2 drugs quantitation. High concentrations of infliximab during treatment initiation reduce the development of ATI, and the absence of ATI may be associated with prolonged maintenance of infliximab.

Serum infliximab concentration

Serum infliximab and antibodies against infliximab (Prometheus Laboratories, San Diego California, USA) were assessed blindly in duplicate, as described previously.12 Antibodies against infliximab were reported as negative when the concentration was <1.69 μg/ml and the serum infliximab was <1.40 μg/ml, and as positive when the concentration exceeded 1.69 μg/ml and the serum infliximab was 2021-02-18 · Background The threshold concentration of infliximab during maintenance therapy has not been well-defined in relation to histologic remission. The aim of the study is to dentify the maintenance-phase infliximab concentration associated with histologic remission in inflammatory bowel disease patients (IBD).

1, 2, 3 Recently, several prospective trials have identified concentration-based dosing as a cost-effective alternative to clinically based dosing. 4, 5 However, dosing could only be adapted at the next infusion At week 14 of treatment, patients were randomly assigned (1:1:1) to 3 infliximab maintenance groups: dose increases (2 maximum) in steps of 2.5 mg/kg based on clinical symptoms and biomarker analysis and/or serum infliximab concentrations (dose intensification strategy [DIS]1 group); dose increase from 5 to 10 mg/kg based on the same criteria (DIS2 group); dose increase to 10 mg/kg based on clinical symptoms alone (controls). Patients' CD activity index scores, levels of C-reactive protein, fecal levels of calprotectin, and serum concentrations of infliximab were determined at baseline and at weeks 2, 4, 6, 12, and 14 Provides infliximab drug concentration levels as well as levels of anti-infliximab antibodies.

Serum infliximab concentration




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. 25 It is hypothesized

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. 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. 25 It is hypothesized 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. 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.
