Changes in serum trough levels of infliximab during treatment intensification but not in anti-infliximab antibody detection are associated with clinical outcomes after therapeutic failure in Crohn's disease. J Crohns Colitis 2015; 9:238–245. The serum concentration of Infliximab immediately prior to re-infusion (trough level) provides important information and should be used to inform dosing, clinical management and appropriate ADA testing; trough drug levels should be monitored during any changes in dosing regimen. Several studies have identified different factors to be associated with sustained clinical response to infliximab.

Trough level quantitation for evaluation of patients with loss of response to infliximab and infliximab-dyyb Clinical Information Infliximab (Remicade, Renflexis, Inflectra) is a chimeric immunoglobulin (IgG1 kappa) targeting tumor necrosis factor-alpha (TNF-a), and it is currently FDA-approved for the treatment of multiple inflammatory conditions.

2014-08-22 2016-01-01 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. Decreased trough level of infliximab (TLI) is associated with diminished efficacy in patients with Crohn disease (CD). We examined whether TLI at 14 weeks subsequent to the start of infliximab (IFX) treatment would impact long-term clinical course. Serum IFX levels and antibodies to IFX (ATI) at 14 and 54 weeks after IFX administration were measured in 12 patients with mild to moderate CD. For infliximab trough concentrations 5.0 mcg/mL or less, testing for antibodies to infliximab (ATI) is suggested. For infliximab trough concentrations above 5.0 mcg/mL, the presence of ATI is unlikely; patients experiencing loss of response to infliximab may benefit from an increased dose or a … 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.

Steenholdt C, Bendtzen K, Brynskov J, et al: Cut-off levels and diagnostic accuracy of infliximab trough levels and Se hela listan på hindawi.com At week 54, the trough serum levels of infliximab varied more than 100‐fold in this group, implying marked differences among subjects in exposure to infliximab. The basis for this individual variability is unknown, but it may be an effect of antibodies to infliximab for some subjects and of metabolic differences for others. 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. 2019-05-08 · The following keywords were included, alone or in combination: “Crohn’s disease”, “ulcerative colitis”, “inflammatory bowel disease”, “vedolizumab”, “trough levels”, “serum levels”, and “therapeutic drug monitoring”.

Gut 2014;63:1721–7. Inter-individual variability in infliximab levels in patients with low DAS28 was high (median 1.4 mg/L, IQR 3.35), with 31% (95%CI: 20-42%) having low (<1 mg/L) and 14% (95%CI 5–22) high trough levels (>5 mg/L). 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.

Currently, trough levels above 3–5 mg/mL are considered adequate but in fistulazing disease target levels may be higher (~10 mg/mL or more).

Serum trough showed that serum inﬂiximab trough concentrations (TCs) are correlated with clinical response, clinical remission, and mucosal healing in patients with IBD.9–12 In general, low inﬂiximab TCs and the presence of ATI are associated with worse clinical outcomes and an inﬂiximab TC within the interval of 3–7 mg/mL during maintenance 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. Several studies have identified different factors to be associated with sustained clinical response to infliximab. 5 – 8 Available data suggest a relationship between clinical efficacy and serum trough levels of infliximab, while detection of antibodies to infliximab (ATI) as such seems to be less relevant parameter. 6, 9 Concomitant 19.
