detectable pre-infusion anti-infliximab antibodies (0/20 patients, p < 0.001). 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%. For serum infliximab levels, a cut point of 0.98 μg/mL was calculated; the false positive rate with this cut point was 5%. 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).

Clinical and imaging efficacy of infliximab in HLA-B27-Positive patients with challenge without detectable serum antibodies to gluten or transglutaminase. 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). Concurrent immunosuppression was not associated with clinical outcomes.

17 Oct 2020 Infliximab is usually either not detectable in breastmilk or detectable at Her infants had detectable serum infliximab levels until 12 months of Detectable drug levels are associated with better clinical outcome as Maser EA , et al.

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. Infliximab is usually not detectable in breastmilk and absorption is unlikely because it is probably destroyed in the infant’s gastrointestinal tract.

In a large, double-blind, randomised study involving patients with active, refractory Crohn’s disease, significantly more recipients of intravenous infliximab, compared In all, 16/76 patients (22.4%) presented detectable infliximab antibodies in the serum. Ten antibody-positive patients had an intensification of infliximab therapy and six (60%) demonstrated a clinical response. After intensification of infliximab therapy the infliximab antibody concentration decreased in … 2017-03-31 Investigating the link between disease activity and infliximab serum levels in rheumatoid arthritis patients L. Valor1, D. Hernández-Flórez 1, I. de la Torre , T. del Rio 1, J.C. Nieto , detectable IFX levels were any predictor of clinical disease activity. 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).

Favorable efficacy was observed in patients with detectable serum infliximab levels (≥0.1 μg/mL) at baseline. 2006-10-01 detectable pre-infusion anti-infliximab antibodies (0/20 patients, p < 0.001). Conclusions: Most anti-infliximab forming patients have detectable anti-infliximab antibodies halfway through an Measurement of antibodies to infliximab or adalimumab in a patient receiving treatment with infliximab or adalimumab, either alone or as a combination test that includes the measurement of serum infliximab levels or serum adalimumab levels is not covered as the evidence is insufficient to determine the effects of the technology on health outcomes. Measurement of Serum Antibodies to Infliximab and Adalimumab Policy Number: 2.04.84 Last Review: 12/2013 Origination: 2/1/2013 Next Review: 12/2014 Policy Blue Cross and Blue Shield of Kansas City (Blue KC) will not provide coverage for measurement of 2010-02-01 2015-08-19 Serum concentrations of infliximab and antibodies to infliximab (ATI) and DAS28 and EULAR clinical response parameters were recorded for one year. Analyses were performed in three patient groups that were defined by infliximab serum concentration prior to treatment enhancement: No detectable, Low (< 1.1 µg/mL) or High (≥ 1.1 µg/mL) drug levels. 2019-10-03 Development of antibodies to infliximab increased infliximab clearance. At 8 weeks after a maintenance dose of 3 to 10 mg/kg of REMICADE, median infliximab serum concentrations ranged from approximately 0.5 to 6 mcg/mL; however, infliximab concentrations were not detectable (<0.1 mcg/mL) in patients who became positive for antibodies to infliximab.
