Predictors of Infliximab Clearance. Increased body weight, increased ADA concentrations, decreased serum albumin concentrations, and increased CRP or serum glucose concentrations were each predictive of higher baseline infliximab clearance (Figure 1).Over the range of body weight in the database (34–139 kg), baseline clearance ranged from 0.16 to 0.43 L/day.

2007-09-01 Clinical utility of antihuman lambda chain-based enzyme-linked immunosorbent assay (ELISA) versus double antigen ELISA for the detection of anti-infliximab antibodies A detectable serum infliximab was associated with higher rates of remission (69% vs 15%; p<0.001) and endoscopic improvement (76% vs 28%, p<0.001). An undetectable serum infliximab predicted an increased risk for colectomy (55% vs 7%, OR 9.3; 95% CI 2.9 to 29.9; p<0.001). A detectable serum infliximab was associated with higher rates of remission (69% vs 15%; p<0.001) and endoscopic improvement (76% vs 28%, p<0.001). An undetectable serum infliximab predicted an increased risk for colectomy (55% vs 7%, OR 9.3; 95% CI 2.9 to 29.9; p<0.001).

Trough serum infliximab: a predictive factor of clinical outcome for infliximab treatment in acute ulcerative colitis. The rate of clinical remission was higher for patients with a detectable trough serum infliximab compared with patients in whom serum infliximab was  reaction with detectable antibodies to infliximab, 7.7; 95% CI, 1.88–31.3; P [ .004) . CONCLUSIONS: long-term treatment success and serial serum samples.

One hundred serum samples that previously had tested positive with ELISA were reanalyzed by the new method. There was a high correlation between the 2 methods for ATI levels (p<0.001).

Infliximab Level and Anti-drug Antibody for IBD - When treatment of inflammatory bowel disease with infliximab or its biosimilar fails, a physician may need to consider treatment options, such as adjusting dose or dosing intervals, switching to a different TNF blocker, or switching to a non-TNF blocker.

Results Based upon analysis of 1487 samples, 77.1% of patients had detectable and 22.9% had undetectable infliximab concentrations, of which 9.5% and 71.8%, respectively, were positive for ATI. An infliximab concentration of >2.79 μg/mL (area under the curve (AUC)=0.681; 95% CI 0.632 to 0.731) and ATI concentration of <3.15 U/mL (AUC=0.632; 95% CI 0.589 to 0.676) were associated with remission. ATI were not detectable in serum if infliximab concentration was ≥0.3 μg/mL and were regarded as inconclusive for ATI. For the pharmaco-economic evaluation of the optimization phase, infliximab costs of the optimized treatment regimen were compared with those of the treatment regimen at baseline in year 2012 values. Infliximab ADA formation is defined as any detectable amount of ADA in the absence of detectable serum infliximab (measured by enzyme-linked immunosorbent assay, ELISA). Secondary Outcome Measures : Infliximab levels were measured by ELISA (lowest detectable level = 0.1 μg/ml). Modeling serum profiles for each of the dosing regimens were used to determine the benefit of a dose increase versus a change in dosing interval frequency to achieve adequate clinical response. Results: If infliximab level is sub-therapeutic and total infliximab anti-drug antibody is detected: Detectable serum infliximab anti-drug antibody may cause accelerated infliximab clearance leading to reduced trough levels and a compromised clinical response. 2020-10-20 · Infliximab serum concentrations remained detectable in one infant until 12 months of age (Julsgaard 2016).

Conclusions: Most anti-infliximab forming patients have detectable anti-infliximab antibodies halfway through an Se hela listan på academic.oup.com Detectable trough serum infliximab was present in 39% of patients and, among patients with undetectable infliximab, 41% were antibody positive and 20% were antibody negative. For antibody-positive and antibody-negative patients, rates of remission (18% vs 14%), endoscopic improvement (25% vs 35%) and colectomy (52% vs 59%) were not different. rate with this cut point was 3%.
