There was no significant difference in observed ACR20 response rates across the infliximab treatment groups, however, ACR50 and ACR70 response rates increased with increased serum trough levels. 5.

Although ACR20 response rates were not significantly different among the 4 infliximab‐treatment groups, ACR50 and ACR70 response rates showed a trend toward increasing with increasing doses of infliximab (Figure 3).

Detectable trough level of infliximab, but less than 5 micrograms/ml. Infliximab dose increased by 50 mg or 100 mg. Trough levels of infliximab of greater than 10 micrograms/ml on at least 2 occasions. Infliximab dose reduced.

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 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.

Drug trough levels and anti-drug levels were determined using ELISA-based assays. Regarding the serum IFX dosage, patients with higher relative C-reactive

However, data in children are lacking.

Data from separate clinical studies suggest an optimal infliximab trough concentration of greater than 3.8 or 6-10 mcg/mL.

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.

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 Objective: To investigate the relationship between serum trough infliximab levels and clinical response to infliximab treatment in patients with rheumatoid arthritis (RA). Methods: Disease activity and serum trough infliximab levels before and 2, 6, and 14 weeks after initiation of infliximab treatment at a dose of 3 mg/kg in a cohort of 105 patients with RA were assessed. 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.

Trough serum levels of infliximab corresponded with the magnitude of ACR response. There was no significant difference in observed ACR20 response rates across the infliximab treatment groups, however, ACR50 and ACR70 response rates increased with increased serum trough levels.

Reactive testing was done in both groups if the disease lost response or there was a concern for side effects because of antibody formation. Infliximab Drug Levels SPECIMEN.
