Subtherapeutic drug concentrations contribute to both primary and secondary nonresponse to infliximab in children with Crohn's disease (CD). The aim of this study was to evaluate treatment outcomes and infliximab concentrations at infusions 2 and 3 with an objective to establish infliximab targets during induction for primary responders.
Infliximab is increasingly used to treat neurosarcoidosis. We aimed to determine the efficacy and tolerance of an infliximab biosimilar for treating neurosarcoidosis.
Biological therapy is currently widely used to treat IBD. Infliximab, adalimumab and golimumab are currently licensed anti-TNF therapies. Biosimilar anti-TNF monoclonal antibodies are increasingly used. Anti-TNF therapies are widely used and their adverse effects are well characterised, and may cause significant morbidity and mortality in a small proportion of exposed patients. Gastroenterologists...
Options for medical management of patients with acute severe colitis (ASC) failing IV steroids are limited and include rescue therapy with either infliximab or ciclosporin. In patients failing infliximab, second-line rescue therapy with ciclosporin is an alternative. The aim of this study was to investigate the efficacy and safety of ciclosporin in patients with steroid-refractory ASC failing firs...
Psoriatic arthritis (PsA) is associated with progressive joint destruction and reduced quality of life. The time until a drug treatment starts to show an effect (TOA) is important for preventing joint destruction. The objective was to assess the time until onset of action of drugs when treating PsA. A systematic review of PsA drug trials was performed. Outcomes were: time until 25% of patients (TO...
In patients undergoing immunotherapy, the quality of the immune response is reduced, which may negatively affect the efficacy of vaccination. This study was conducted in order to evaluate the efficacy of the hepatitis B virus (HBV) vaccine in patients using immunomodulators. Seronegative patients for HBV who were using biological agents, were included in the study. The vaccination was administered...
The introduction of tumor necrosis factor-alpha (TNF-α)-targeting drugs has given new opportunities in the treatment of various inflammatory rheumatic diseases and has been the most important development in the treatment of spondyloarthritis (SpA). However, the increasing use and longer follow-up periods of treatment also pose risks of developing various adverse effects ranging from common ones i...
Drug hypersensitivity reactions to infliximab have been reported in pediatric patients. At times, these patients may need infliximab administration in spite of hypersensitivity. However, only a few reports of desensitization protocols are available in the literature in pediatric patients.
The aim of the study was to identify factors influencing infliximab (IFX) trough levels (TL) in patients with inflammatory bowel disease (IBD).
Therapeutic failure of infliximab therapy in patients with ulcerative colitis remains a challenge even two decades after its approval. Therapeutic drug monitoring (TDM) has shown value during maintenance therapy, but induction therapy is still unexplored. The patients may be primary nonresponders or underexposed with the standard dosing regimen. We aimed to (i) develop a population pharmacokinetic...
There is evidence that it is safe and effective for patients with inflammatory bowel diseases (IBD) to switch from maintenance therapy with an original infliximab drug to a biosimilar, but little is known about outcomes of reverse switches and/or multiple switches. We aimed to evaluate the effects of a reverse switch (from a biosimilar to Remicade) in a real-life cohort.
Pyoderma gangrenosum (PG) is a rare ulcerative skin disease that presents a therapeutic challenge. Tumour necrosis factor alpha (TNFα) inhibitors have been reported to successfully control PG. Our aim was to systematically evaluate and compare the clinical effectiveness of TNFα inhibitors in adults with PG. A literature search including databases such as PubMed, Embase, Scopus, and Web of Scienc...
Infliximab is an effective salvage therapy in acute severe ulcerative colitis; however, the optimal dosing strategy is unknown. We performed a systematic review and meta-analysis to examine the impact of infliximab dosage and intensification on colectomy-free survival in acute severe ulcerative colitis.
Circulating infliximab (IFX) concentrations correlate with clinical outcomes, forming the basis of the IFX concentration monitoring in patients with Crohn's disease. This study aims to investigate and refine the exposure-response relationship by linking the disease activity markers 'Crohn's disease activity index' (CDAI) and C-reactive protein (CRP) to IFX exposure. In addition, we aim to explore ...
The aim of this study was to quantify the production of T-cell cytokines from the peripheral blood mononuclear cells (PBMCs) of RA patients before and after treatment with anti-tumor necrosis factor (TNF)-α infliximab (IFX).
There are limited data concerning infliximab drug monitoring during de-escalation of the treatment of inflammatory bowel disease (IBD).
To search the predictive factors of infliximab resistance in intravenous immunoglobulin (IVIG)-resistant Kawasaki disease (KD) patients.
The aim of the present meta-analysis was to systematically assess the efficacy of the various treatments available for moderate to severe psoriasis. PubMed and Embase databases were systematically searched to select relevant studies up to February 2015. Odds ratios (ORs) and their 95% confidence intervals (CIs) were used as effect estimates. In addition, the Psoriasis Area and Severity Index (PASI...
Anti-TNF therapies infliximab (IFX), adalimumab (ADA), and golimumab (GOL) are approved for treating moderate to severe ulcerative colitis (UC). In UC, only the switch from IFX to ADA has been investigated, reaching no more than 10-43% remission rates at 12 months.
Mucosal healing is an important treatment goal in Crohn's disease. We investigated the association between serum infliximab trough levels and mucosal healing, and the infliximab cut-off levels required for mucosal healing in paediatric patients.
Optimization strategies with infliximab (IFX) are increasingly used as rescue therapy for steroid refractory acute severe ulcerative colitis (ASUC). We aim to determine if intensified IFX induction improves colectomy rate and identifies outcome predictors.
