We propose that serum levels of 6-10 μg/mL for infliximab and 8-12 μg/mL for adalimumab are required to achieve mucosal healing in 80%-90% of patients with IBD, and that this could be considered as a "therapeutic window." Exceeding these levels produces only a negligible gain in proportion of patients with mucosal healing.

Infliximab, a chimeric monoclonal antibody, is used to treat rheumatoid arthritis, psoriatic arthritis, Crohn's disease, and other autoimmune diseases.

However, if the brand of infliximab called Inflectra has been prescribed, no payment is Infliximab is an anti-tumour necrosis factor-α (TNF-α) mouse–human IgG1/κ antibody used to treat patients with rheumatoid arthritis (RA) and other inflammatory diseases. Unfortunately, response failure and side-effects due to immunogenicity of the drug are not rare. 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. Serum infliximab levels were measured using an enzyme-linked immunosorbent assay as previously described (8).

Methods. We included 154 children (age < 18 years) from 17 hospitals who had been diagnosed with IBD and actively treated with infliximab or adalimumab. In a previous study infliximab was used as a demonstrator molecule and the general workflow was applied for the development of a UPLC–MS method for infliximab in rat serum. The UPLC–MS/MS study of infliximab [ 14 ] was mainly focused on the optimization of the sample purification part (using protein A magnetic beads) and the analyte processing part (elution/denaturation, reduction The correlation between serum infliximab concentrations at different time points was assessed using the Pearson correlation coefficient. Serum infliximab concentration data were compared between patients with and without the specified efficacy outcomes using a 2-sided Wilcoxon–Mann–Whitney, 2-sample, rank-sum test. Postinduction serum infliximab trough level and decrease of C-reactive protein level are associated with durable sustained response to infliximab: a retrospective analysis of the ACCENT I trial.

Infliximab (Remicade) was associated to the development of anti-Infliximab antibodies, even some were reported to be neutralizing, in various percentages of patients during therapy with the drug Remicade®.

Gut. 2014;63:1721–7. CAS Article PubMed PubMed Central Google Scholar Repeated administration of infliximab (5 mg/kg at 0, 2 and 6 weeks in fistulising Crohn's disease, 3 or 10 mg/kg every 4 or 8 weeks in rheumatoid arthritis) resulted in a slight accumulation of infliximab in serum after the second dose. No further clinically relevant accumulation was observed.

There is a significant difference between serum infliximab levels in patients with IBD in remission, compared with those who relapse. A trough threshold during maintenance > 2 µg/ml is associated with a greater probability of clinical remission and mucosal healing. Minimum Infliximab Dosage for Keeping Serum Infliximab Levels Greater than 1 µg/mL among Patients with Rheumatoid Arthritis.

Patients that develop HACA may experience infusion reactions and/or a reduced duration of efficacy of infliximab. Infliximab, a chimeric monoclonal antibody, is used to treat rheumatoid arthritis, psoriatic arthritis, Crohn’s disease, and other autoimmune diseases. Clinical responses are different among patients due to inadequate amount of drug circulating in the blood. Optimizing infliximab (IFX) treatment in pediatric patients with inflammatory bowel disease (IBD) by using serum infliximab (S-IFX) trough levels and antibodies to IFX is recommended. There is need for studies assessing this strategy in clinical practice.
