Impact of Synbiotic Intake on Liver Metabolism in Metabolically Healthy Participants and Its Potential Preventive Effect on Metabolic-Dysfunction-Associated Fatty Liver Disease (MAFLD): A Randomized, Placebo-Controlled, Double-Blinded Clinical Trial. Nutrients 2024; 16:1300. [PMID: 38732547 PMCID: PMC11085762 DOI: 10.3390/nu16091300] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Revised: 04/21/2024] [Accepted: 04/24/2024] [Indexed: 05/13/2024] Open
Abstract
Synbiotics modulate the gut microbiome and contribute to the prevention of liver diseases such as metabolic-dysfunction-associated fatty liver disease (MAFLD). This study aimed to evaluate the effect of a randomized, placebo-controlled, double-blinded seven-week intervention trial on the liver metabolism in 117 metabolically healthy male participants. Anthropometric data, blood parameters, and stool samples were analyzed using linear mixed models. After seven weeks of intervention, there was a significant reduction in alanine aminotransferase (ALT) in the synbiotic group compared to the placebo group (-14.92%, CI: -26.60--3.23%, p = 0.013). A stratified analysis according to body fat percentage revealed a significant decrease in ALT (-20.70%, CI: -40.88--0.53%, p = 0.045) in participants with an elevated body fat percentage. Further, a significant change in microbiome composition (1.16, CI: 0.06-2.25, p = 0.039) in this group was found, while the microbial composition remained stable upon intervention in the group with physiological body fat. The 7-week synbiotic intervention reduced ALT levels, especially in participants with an elevated body fat percentage, possibly due to modulation of the gut microbiome. Synbiotic intake may be helpful in delaying the progression of MAFLD and could be used in addition to the recommended lifestyle modification therapy.

Abstract
Precision-dosing models forecast infliximab doses to achieve targeted trough concentrations in patients with inflammatory bowel disease (IBD). These models have shown to reduce nonresponse and improve patient outcomes. We compared infliximab doses determined by iDOSE precision dosing with standard dosing, and the associated drug costs, in patients with IBD. In this retrospective study, patients with IBD treated with infliximab every 8 weeks at 5 mg/kg were included. An infliximab dose was named dose X if 3 previous infliximab doses, laboratory values including trough infliximab concentrations, and the patient's weight were recorded. The actual dose X was compared to an iDOSE-predicted dose X. Net drug use and costs were evaluated. A total of 174 patients-56% men; median age, 36 (interquartile range, 29-47) years; 135 with Crohn disease; and 31 with ulcerative colitis-were included, with 417 dose X recordings. Median prior infliximab therapy was 2 (0-4) years. Comparing actual dose X with predicted dose X, 52% and 32% of doses were subtherapeutic when aiming for trough concentrations of 5-10 and 3-7 μg/mL, respectively. Treatment costs increased by 102% and 29% for the 2 trough ranges, respectively. On multivariate regression analysis, subtherapeutic infliximab concentrations were associated with ulcerative colitis compared with Crohn disease (odds ratio, 9.81; 95% confidence interval, 1.28-75.40; P = .028) and predose X infliximab trough concentration [odds ratio, 0.07; 95% confidence interval, 0.03-0.15; P < .001]. Over half of maintenance infliximab drug doses were too low to achieve infliximab blood concentrations of 5 μg/mL or greater. While applying precision dosing may improve patient outcomes, drug costs could be considerably greater.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) therapies now utilise higher doses of immunomodulatory and biologic therapies, predisposing patients to an increased risk of infections. AIMS We aimed to determine whether infections were associated with high anti-tumour necrosis factor (TNF) drug levels in IBD and to quantify the risk and consequences of infections. METHODS Two retrospective studies were performed, a descriptive cohort study and a matched case-control study. For the matched case-control study, cases of infection occurring on anti-TNF agents were matched in a 1:2 ratio to controls of anti-TNF treated patients without infections. RESULTS In the descriptive study, 76 infections occurred in 60 patients, including 49 bacterial, 24 viral, four fungal and four parasitic. Of these, 61 (80.3%) were on biologics, 49 (64.5%) on immunomodulators and 11 (14.5%) on corticosteroids. Thirty-four (44.7%) were on combination therapy, 27 (35.5%) on biologic monotherapy and 15 (19.7%) on immunomodulator monotherapy. Median anti-TNF drug levels in infection cases were 3.9 μg/mL for infliximab and 6.0 μg/mL for adalimumab. In the case-control study, 32 cases of infection in 27 anti-TNF treated patients were matched with 64 anti-TNF treated controls without infections. Among infection cases, 59.5% were on combination therapy versus 40.6% on biologic monotherapy (P = 0.59). Median drug levels for cases and controls respectively were 3.9 μg/mL versus 5.5 μg/mL for infliximab (P = 0.72) and 6.0 μg/mL versus 9.9 μg/mL for adalimumab (P = 0.34). CONCLUSION Infections in patients with IBD were common, and the risk was highest with combination therapy. Infections were not associated with high serum anti-TNF levels.

Abstract
BACKGROUND Carriers of the human leucocyte antigen variant HLADQA1*05 (rs2097432) are at risk of developing antibodies against infliximab and adalimumab with reduced tumor necrosis factor (TNF) antagonist persistence. The impact of proactive therapeutic drug monitoring (PTDM) on this association has been barely assessed. METHODS We conducted a retrospective single-center cohort study including patients with inflammatory bowel disease starting anti-TNF therapy between January 2017 and March 2021. Proactive therapeutic drug monitoring was defined as periodic drug level measurement (≥2 determinations during the first year of treatment and ≥1/annual determination during the following years), regardless of clinical condition, followed by dose optimization. Variables associated with treatment persistence were assessed with multivariable Cox regression analysis. RESULTS A total of 112 patients were included, 52 (46.4%) HLA-DQA1*05 carriers, with a median follow-up of 73.9 (interquartile range, 35.4-133.1) weeks. Combination therapy with thiopurines was more frequent among HLA-DQA1*05 noncarriers (28 [46.7%] vs 12 [23.1%]; P = .01). Clinical remission rates at week 14 (77.9% vs 73.9%; P = .69) and 56 (73.2% vs 68.4%; P = .64) were similar between HLA-DQA1*05 noncarriers and carriers. Drug persistence was higher among HLA-DQA1*05 carriers (hazard ratio [HR], 0.32; 95% confidence interval, 0.14-0.71; P = .01). Multivariable Cox regression analysis identified systemic steroids at anti-TNF initiation (HR, 4; 95% confidence interval, 1.7-9.7) as a risk factor and HLA-DQA1*05 carriers (HR, 0.31; 95% confidence interval, 0.12-0.81) as a protective factor of treatment cessation. CONCLUSION In adult patients with PTDM, a positive HLA-DQA1*05 genotype does not associate a higher risk of treatment cessation nor worse clinical outcomes.

Abstract
In the last two decades, biologicals have become essential in treating children and adolescents with inflammatory bowel disease. TNF-α inhibitors (infliximab, adalimumab and golimumab) are preferentially used. Recent studies suggest that early application of TNF-α inhibitors is beneficial to inducing disease remission and preventing complications such as development of penetrating ulcers and fistulas. However, treatment failure occurs in about one third of pediatric patients. Particularly, children and adolescents differ in drug clearance, emphasizing the importance of pharmacokinetic drug monitoring in the pediatric setting. Here, current data on the choice and effectiveness of biologicals and therapeutic drug monitoring strategies are reviewed.

90K/Mac-2 BP Is a New Predictive Biomarker of Response to Infliximab Therapy in IBD Patients. Int J Mol Sci 2023; 24:ijms24043955.

Abstract
Inflammatory bowel diseases (IBD), comprising Crohn's disease (CD) and Ulcerative Colitis (UC), are multifactorial disorders characterized by a chronic inflammatory status with the secretion of cytokines and immune mediators. Biologic drugs targeting pro-inflammatory cytokines, such as infliximab, are broadly used in the treatment of IBD patients, but some patients lose responsiveness after an initial success. The research into new biomarkers is crucial for advancing personalized therapies and monitoring the response to biologics. The aim of this single center, observational study is to analyze the relationship between serum levels of 90K/Mac-2 BP and the response to infliximab, in a cohort of 48 IBD patients (30 CD and 18 UC), enrolled from February 2017 to December 2018. In our IBD cohort, high 90K serum levels were found at baseline in patients who then developed anti-infliximab antibodies at the fifth infusion (22 weeks after the first), becoming non-responders (9.76 ± 4.65 µg/mL compared to 6.53 ± 3.29 µg/mL in responder patients, p = 0.005). This difference was significant in the total cohort and in CD, but not significant in UC. We then analyzed the relationship between serum levels of 90K, C-reactive protein (CRP), and Fecal calprotectin. A significant positive correlation was found at baseline between 90K and CRP, the most common serum inflammation marker (R = 0.42, p = 0.0032). We concluded that circulating 90K could be considered a new non-invasive biomarker for monitoring the response to infliximab. Furthermore, 90K serum level determination, before the first infliximab infusion, in association with other inflammatory markers such as CRP, could assist in the choice of biologics for the treatment of IBD patients, thereby obviating the need for a drug switch due to loss of response, and so improving clinical practice and patient care.

Abstract
INTRODUCTION Monitoring plasma levels of Infliximab plays an important role in optimising treatment in patients with inflammatory bowel disease (IBD). The aim of the following study has been to determine the predictive potential of monitoring infliximab plasma levels for sustained clinical response and evaluate its usefulness to improve treatment efficacy and symptom control, in patients with IBD. METHODS This single-centre retrospective study (2017-2019) included patients diagnosed with IBD treated with infliximab. Serum levels and the occurrence of drug-associated immunogenicity were analysed at Week 8 post-induction and 6, 12 and 24 months. Clinical parameters and inflammatory markers were recorded such as subjective global assessment (SGA), C-reactive protein (CRP) and faecal calprotectin (FC). Factors associated with early discontinuation and dose intensification of infliximab were determined. RESULTS Multivariate analysis determined that IFX concentrations>7μg/mL at week 8, and at 6 months, are associated with inflammatory remission (p=0.046, 0.045). IFX>7μg/mL at 12 months predicted remission at 18 months of treatment (p=0.006). IFX values>3μg/mL at 12 months are associated with stable SGA at 18 months (p=0.001). Such values at 18 months are associated with stable SGA at 24 months (p=0.044). CONCLUSIONS AND RELEVANCE The predictive potential of monitoring IFX plasma levels as a strategy to evaluate sustained long-term clinical response was confirmed. Our results highlight the importance of its introduction into routine clinical practice to enable early identification of non-responders, treatment optimisation, relapse prevention and improve long-term therapy maintenance.

Abstract
BACKGROUND It is uncertain if higher infliximab trough levels (TLs) confer a greater risk of infectious/noninfectious complications (IC/NIC). We aimed to assess the risk of IC and NIC in patients with different TLs. METHODS We retrospectively evaluated a cohort of Crohn's disease (CD) patients treated with infliximab who underwent therapeutic drug monitoring (TDM), at a tertiary inflammatory bowel disease center, between January 1, 2010, and December 1, 2019. TDM was defined as checking of infliximab trough and antibody levels within a 48-hour period before administration. Patients with a minimum of 3-month assessment pre-TDM and post-TDM were included. In the case of multiple TDMs, the highest TL was considered, and patients were distributed across 4 predefined TL groups (A: <5 µg/mL, B: 5 to 10 µg/mL, C: 10 to 15 µg/mL, and D: ≥15 µg/mL). Rates of IC and NIC during the 3-month prior and following TDM were compared across the groups. In addition, duration of exposure, in terms of months up to TDM, was collected to analyze differences in rates of IC and NIC. RESULTS Our study included 341 CD patients (median age: 35 y, 58% men). IC and NIC occurred in 52 (15%) and 30 (9%) patients, respectively. Rates of IC and NIC were similar across the 4 TL groups ( P =0.9 and 0.7, respectively for IC and NIC). On multivariable analysis, exposure to infliximab >40 months (as determined by receiver operating characteristic curve analysis) was associated with decreased odds for IC (adjusted odds ratio=0.51, P =0.04), but not NIC (adjusted odds ratio=0.72, P =0.46). CONCLUSIONS In this large CD cohort, there was no association between infliximab TL and risk of short-term IC or NIC. Interestingly, a shorter duration of exposure predicted higher rates of IC. This supports the safety of targeting higher infliximab TLs when necessary and greater vigilance during the early stages of treatment.

Abstract
Monoclonal antibodies (MAbs) have revolutionized the treatment of many chronic inflammatory diseases, including inflammatory bowel disease (IBD). IBD is a term that comprises two quite similar, yet distinctive, disorders—Crohn’s disease (CD) and ulcerative colitis (UC). Two blockbuster MAbs, infliximab (IFX) and adalimumab (ADL), transformed the pharmacological approach of treating CD and UC. However, due to the complex interplay of pharmacology and immunology, MAbs face challenges related to their immunogenicity, effectiveness, and safety. To ease the burden of IBD and other severe diseases, biosimilars have emerged as a cost-effective alternative to an originator product. According to the current knowledge, biosimilars of IFX and ADL in IBD patients are shown to be as safe and effective as their originators. The future of biosimilars, in general, is promising due to the potential of making the health care system more sustainable. However, their use is accompanied by misconceptions regarding their effectiveness and safety, as well as by controversy regarding their interchangeability. Hence, until a scientific consensus is achieved, scientific data on the long-term effectiveness and safety of biosimilars are needed.

Abstract
Anti-tumor necrosis factor (anti-TNF) therapy has been successfully used as first-line biologic treatment for moderate-to-severe inflammatory bowel disease (IBD), in both “step-up” and “top-down” approaches, and has become a cornerstone of IBD management. However, in a proportion of patients the effectiveness of anti-TNF therapy is sub-optimal. Either patients do not achieve adequate initial response (primary non-response) or they lose response after initial success (loss of response). Therapeutic drug monitoring determines drug serum concentrations and the presence of anti-drug antibodies (ADAbs) and can help guide treatment optimization to improve patient outcomes. For patients with low drug concentrations who are ADAb-negative or display low levels of ADAbs, dose escalation is recommended. Should response remain unchanged following dose optimization the question whether to switch within class (anti-TNF) or out of class (different mechanism of action) arises. If ADAb levels are high and the patient has previously benefited from anti-TNF therapy, then switching within class is a viable option as ADAbs are molecule specific. Addition of an immunomodulator may lead to a decrease in ADAbs and a regaining of response in a proportion of patients. If a patient does not achieve a robust therapeutic response with an initial anti-TNF despite adequate drug levels, then switching out of class is appropriate. In conjunction with the guidance above, other factors including patient preference, age, comorbidities, disease phenotype, extra-intestinal manifestations, and treatment costs need to be factored into the treatment decision. In this review we discuss current evidence in this field and provide guidance on therapeutic decision-making in clinical situations.

[PMID: 35631594 PMCID: PMC9145467 DOI: 10.3390/pharmaceutics14051009] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2022] [Revised: 04/27/2022] [Accepted: 04/30/2022] [Indexed: 02/01/2023] Open
Abstract
Infliximab and adalimumab are monoclonal antibodies against tumor necrosis factor (anti-TNF) used to manage inflammatory bowel disease (IBD). Therapeutic Drug Monitoring (TDM) has been proven to prevent immunogenicity, to achieve better long-term clinical results and to save costs in IBD treatment. The aim of this study was to conduct a systematic review on cost-effectiveness analyses of studies that apply TDM of anti-TNF in IBD and to provide a critical analysis of the best scientific knowledge available in the literature. The quality of the included studies was assessed using Consolidated Health Economic Evaluation Reporting Standards (CHEERS). Cost-effectiveness of the TDM strategies was presented as total costs, cost savings, quality-adjusted life-years (QALY) and incremental cost-effectiveness ratio (ICER). Thirteen studies that examined the health economics of TDM of anti-TNF in IBD from 2013 to 2021 were included. Eight of them (61.5%) achieved a score between 17 and 23 on the CHEERS checklist. The comparison between the TDM strategy and an empirical strategy was cost saving. The ICER between reactive TDM and an empirical strategy was dominated (favorable) by reactive TDM, whereas the ICER value for proactive TDM compared to an empirical strategy ranged from EUR 56,845 to 3,901,554. This systematic review demonstrated that a TDM strategy is cost-effective or cost-saving in IBD.

Delaying an infliximab infusion by more than 3 days is associated with a significant reduction in trough levels but not with clinical worsening. Therap Adv Gastroenterol 2022; 15:17562848221083395. [PMID: 35646158 PMCID: PMC9133860 DOI: 10.1177/17562848221083395] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Accepted: 02/08/2022] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND Higher infliximab trough levels (TLs) correlate with better clinical, inflammatory, and endoscopic outcomes among inflammatory bowel disease (IBD) patients. Although standard scheduled infliximab therapy regimen consists of infusions at pre-defined time-points (weeks 0, 2, 6, and every 8 weeks), short-period deviations from therapeutic schedule are common in 'real life', but the pharmacokinetic impact of these deviations has not been explored. In this study, we aim to determine whether short-period deviations from infusion schedule affect infliximab-TL. METHODS A retrospective analysis of all IBD patients receiving infliximab maintenance therapy every 8 weeks was conducted in a tertiary medical center. Patients with anti-drug antibodies, deliberate interval shortening and <3 sequential maintenance sera available were excluded. Associations between time since last infusion and TL were studied. Statistical analysis was performed using generalized estimating equations. RESULTS Out of over 10,000 sera, 2088 sera of 302 maintenance period stable infliximab-therapy-patients met inclusion criteria (median TL 4.1 μg/mL, interquartile range (IQR) 2.3-6.5 μg/mL). A delay beyond 3 days in infusion schedule (n > 59 days since last infusion) was found to significantly affect TL (mean difference in TL 0.9 μg/mL, 95% confidence interval (CI): 0.03-1.9 μg/mL, p < 0.04). Furthermore, among patients with delayed infusions, 80% had TL below 5 μg/mL, in comparison to 55% of patients who were not late (odds ratio (OR): 2.81, CI: 2.02-3.92, p < 0.0001). CONCLUSION Real-life delays of ⩽3 days from infusion protocol can probably be allowed. Delays >3 days culminate in measurable decrease of TL, although effect on clinical outcome is unclear. This needs to be taken into account when interpreting drug-level test results. SUMMARY A total of 2088 sera of 302 maintenance period inflammatory bowel disease (IBD) patients treated with infliximab were analyzed, to assess effect of small deviations from infusion schedule on TLs. A significant decline in patients' trough level (TL) was noted as early as 3 days after scheduled infusion.

Relationship between clinical remission of perianal fistulas in Crohn’s disease and serum adalimumab concentrations: A multi-center cross-sectional study. World J Gastroenterol 2022; 28:961-972.

Abstract
BACKGROUND Crohn’s disease (CD) is complicated by perianal fistulas in approximately 20% of patients. Achieving permanent fistula closure remains a challenge for physicians. An association between serum anti-tumor necrosis factor-α concentrations and clinical outcomes in patients with CD has been demonstrated; however, little information is available on serum adalimumab (ADA) concentrations and remission of perianal fistulas in such patients.
AIM To study the relationship between serum ADA concentrations and clinical remission of CD-associated perianal fistulas.
METHODS This cross-sectional study of patients with CD-associated perianal fistulas treated with ADA was performed at four French hospitals between December 2013 and March 2018. At the time of each serum ADA concentration measurement, we collected information about the patients and their fistulas. The primary study endpoint was clinical remission of fistulas defined as the absence of drainage (in accordance with Present’s criteria), with a PDAI ≤ 4, absence of a seton and assessment of the overall evaluation as favorable by the proctologist at the relevant center. We also assessed fistula healing [defined as being in clinical and radiological (magnetic resonance imaging, MRI) remission] and adverse events.
RESULTS The study cohort comprised 34 patients who underwent 56 evaluations (patients had between one and four evaluations). Fifteen patients had clinical remissions (44%), four of whom had healed fistulas on MRI. Serum ADA concentrations were significantly higher at evaluations in which clinical remission was identified than at evaluations in which it was not [14 (10-16) vs 10 (2-15) μg/mL, P = 0.01]. Serum ADA concentrations were comparable at the times of evaluation of patients with and without healed fistulas [11 (7-14) vs 10 (4-16) μg/mL, P = 0.69]. The adverse event rate did not differ between different serum ADA concentrations.
CONCLUSION We found a significant association between high serum ADA concentrations and clinical remission of CD-associated perianal fistulas.

Abstract
ABSTRACT Anti-tumor necrosis factor alpha (anti-TNFα) therapy is commonly used to treat refractory pediatric inflammatory bowel disease (IBD) and carry risks for adverse events. We aimed to assess the relationship between anti-TNFα trough concentrations and adverse events rate among pediatric patients with IBD. The medical records of pediatric patients with IBD who were treated with anti-TNFα agents from 2015 to 2020 and had sequential monitoring of trough concentration (TC) were reviewed retrospectively for the presence of adverse events. The study cohort included 135 eligible patients (59 [43.7%] girls, mean age at diagnosis 12.9 [±3] years, 111 [82.2%] Crohn disease) who had 1589 measurements of TCs (1037 [63%] infliximab). During a median follow-up period of 1.7 years (IQR 1.1-2.7), we recorded 156 adverse events in 50 patients (37%). Higher TCs were not associated with higher rate of anti-TNFα-related adverse events whereas these events (excluding increase in liver transaminases) were associated with younger age.

Abstract
Inflammatory bowel disease is a chronic disease with variable degrees of extent, severity, and activity. A proportion of patients will have disease that is refractory to licensed therapies, resulting in significant impairment in quality of life. The treatment of these patients involves a systematic approach by the entire multidisciplinary team, with particular consideration given to medical options including unlicensed therapies, surgical interventions, and dietetic and psychological support. The purpose of this review is to guide clinicians through this process and provide an accurate summary of the available evidence for different strategies.

Abstract
Introduction Fecal calprotectin is a biomarker for monitoring inflammatory bowel disease (IBD) activity. Our aim, therefore, was to evaluate two new assays, the point of care test Quantum Blue and the Liaison Calprotectin with respect to the Calprest, commonly used assay, and to determine their performance for IBD diagnosis. Materials and methods We included 73 prospective patients with IBD. Fecal calprotectin was measured and analysed with the routine Calprest assay and two recently introduced assays, the Quantum Blue and the Liaison Calprotectin. Furthermore, we compared the results by Bland and Altman analysis, and Passing-Bablok regression. Results We observed no difference in median calprotectin values obtained by the Calprest (94.6 µg/g, 95%CI 66.5 to 166.1) and Liaison assay (101.0 µg/g, 95%CI 48.1 to 180.1) whereas significantly higher concentrations were obtained with the Quantum Blue assay (240.0 µg/g, 95%CI 119.9 to 353.2). The mean absolute and relative difference between the Calprest and Quantum Blue methods was statistically significant (- 162.3 µg/g and
- 143.1%). Mean absolute difference between the Calprest and Liaison calprotectin methods was positive (2.2 µg/g). The agreement between assays revealed that Quantum Blue and Calprest have fair agreement with Kappa coefficient of 0.38 (95%CI 0.26 to 0.51). Liaison Calprotectin and Calprest revealed moderate agreement with a weak Kappa coefficient of 0.47 (95%CI 0.32 to 0.62). Conclusion Clinicians should be aware of these differences between the assays and avoid comparison of their respective results.

Abstract
BACKGROUND & AIMS Infliximab increases the risk of infection in patients with inflammatory bowel diseases (IBD), but there is controversy over the relationship between drug concentration and infections. We aimed to assess factors associated with infection in infliximab-treated patients, including pharmacokinetic features. METHODS We collected data from 209 patients with IBD (102 men; mean age, 39 y; 159 with Crohn's disease; 54 received combination therapy) who received an infliximab maintenance regimen from November 2016 through April 2017 in France. Data were collected from each infusion visit (total of 640 infusions). Infliximab exposure was estimated based on the area under the curve (AUC) of drug concentration in pharmacokinetic models; individual exposures over the 6-month period were estimated based on the sum of the AUC (ΣAUC). RESULTS The mean infliximab trough level was 5.46 mg/L, and the mean ΣAUC was 3938 ± 1427 mg.d/L. A total of 215 infections were collected from the 640 infusion visits; 123 patients (59%) had at least 1 infection. Factors independently associated with infection after multivariate analysis were smoking (odds ratio [OR], 2.05; P = .046), IBD flare (OR, 2.71; P = .006), and a high ΣAUC of infliximab (above 3234 mg x d/L) (OR, 2.02; P = .02). The ΣAUC was higher in patients with an occurrence of infection (P = .04) and correlated with the number of infections (P = .04). Trough concentration of infliximab alone was not associated with infection. CONCLUSIONS Almost two-thirds of patients treated with infliximab developed an infection; risk was individually correlated with cumulative increase in drug exposure, but not infliximab trough level.

Abstract
The introduction of tumor necrosis factor (TNF) inhibitors has significantly changed the treatment landscape in Crohn's disease (CD). The overall therapeutic achievements with TNF inhibitors such as infliximab, adalimumab, and certolizumab pegol paved the way to push the boundaries of treatment goals beyond symptomatic relief and toward cessation of objective signs of inflammation, including endoscopic remission. Even though these agents are widely used for the treatment of moderate to severe CD, heterogeneity still exists in translating evidence-based guidelines on the use of anti-TNF agents into actual treatment algorithms in CD. This might be due to several reasons including disparities in health expenditure policies; lack of harmonization between countries; and variations in assessment of disease severity, use of disease monitoring tools, or application of treatment targets by physicians. With the advent of biosimilars, patent-free versions of reference biologics are now available to minimize health inequalities in drug availability. In this context, this article aims to provide practical clinical guidance for the use of infliximab and adalimumab biosimilars in patients with moderate to severe CD by outlining different clinical scenarios that patients may encounter during their treatment journey.

Abstract
BACKGROUND In 2018, the European Medicines Agency (EMA) replaced a fixed 50 mg every 4-week maintenance regimen of golimumab for ulcerative colitis (UC) patients weighing <80 kg with new, flexible dosing that allows reactive dose optimization to 100 mg if clinically needed. We analyzed the endoscopic remission rates and pharmacokinetics of this new dosing regimen in real-life settings. METHODS We prospectively recruited 30 consecutive (17 with body weight <80 kg) patients with UC who received golimumab with the new EMA label. The primary endpoint was endoscopic remission (Mayo ≤1) assessed by centrally-read endoscopy at week 14 and year 1. Golimumab concentrations, measured at nine prespecified timepoints, were correlated with endoscopic remission and identified cut-offs. RESULTS Endoscopic remission was achieved in 15/30 (50%) and 10/30 (33%) patients at week 14 and year 1, respectively. Reactive dose optimization to 100 mg maintenance was needed in 13/17 (76%) patients. Golimumab concentrations at week 6 predicted week 14 and year 1 endoscopic remission. Week 6 concentrations >10.7 µg/ml were a strong predictor for achievement and maintenance of endoscopic remission during the first year of treatment, while concentrations <5.1 µg/ml identified the opposite. CONCLUSION One-third of the patients reached and maintained endoscopic remission during the first year of golimumab treatment, but the need for dose optimization to 100 mg every 4 weeks of maintenance was high in patients weighing <80 kg. Golimumab concentrations <5.1 µg/ml at week 6 identified patients who are unlikely to reach and maintain endoscopic remission with the new, flexible EMA label.

Mucosal concentrations of N-acetyl-5-aminosalicylic acid related to endoscopic activity in ulcerative colitis patients with mesalamine. J Gastroenterol Hepatol 2020; 35:1878-1885. [PMID: 32250471 PMCID: PMC7687243 DOI: 10.1111/jgh.15059] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2020] [Revised: 03/23/2020] [Accepted: 03/29/2020] [Indexed: 12/18/2022]
Abstract
BACKGROUND AND AIM 5-Aminosalicylic acid (5-ASA) is a fundamental treatment for mild-to-moderate ulcerative colitis (UC). 5-ASA is taken up into the colonic mucosa and metabolized to N-acetyl-5-ASA (Ac-5-ASA). Few studies have assessed whether mucosal 5-ASA and Ac-5-ASA concentrations are associated with endoscopic remission. This study aimed to investigate differences in 5-ASA and Ac-5-ASA concentrations according to endoscopic activity. METHODS This single-center, prospective, cross-sectional study was conducted between March 2018 and February 2019. UC patients who were administered with 5-ASA medication for at least 8 weeks before sigmoidoscopy were enrolled. Mucosal 5-ASA and Ac-5-ASA concentrations were measured using liquid chromatography with tandem mass spectrometry. The primary endpoint was defined as the difference in mucosal concentrations of 5-ASA and Ac-5-ASA, according to the Mayo endoscopic subscore (MES). RESULTS Mucosal concentrations were analyzed in 50 patients. In the sigmoid colon, the median 5-ASA concentration in patients with MES of 0 (17.3 ng/mg) was significantly higher than MES ≥ 1 (6.4 ng/mg) (P = 0.019). The median 5-ASA concentrations in patients with Ulcerative Colitis Endoscopic Index of Severity ≤ 1 (16.4 ng/mg) were also significantly higher than in patients with Ulcerative Colitis Endoscopic Index of Severity ≥ 2 (4.63 ng/mg) (P = 0.047). In the sigmoid colon, the concentration of Ac-5-ASA was higher in patients with MES of 0 (21.2 ng/mg) than in patients with MES ≥ 1 (5.81 ng/mg) (P = 0.022). CONCLUSIONS The present study showed that mucosal Ac-5-ASA concentrations, as well as 5-ASA concentrations, are higher in UC patients with endoscopic remission. Ac-5-ASA may be useful for a biomarker of 5-ASA efficacy.

Abstract
OBJECTIVE We aimed to provide an evidence-supported update of the ECCO-ESPGHAN guideline on the medical management of paediatric Crohn's disease [CD]. METHODS We formed 10 working groups and formulated 17 PICO-structured clinical questions [Patients, Intervention, Comparator, and Outcome]. A systematic literature search from January 1, 1991 to March 19, 2019 was conducted by a medical librarian using MEDLINE, EMBASE, and Cochrane Central databases. A shortlist of 30 provisional statements were further refined during a consensus meeting in Barcelona in October 2019 and subjected to a vote. In total 22 statements reached ≥ 80% agreement and were retained. RESULTS We established that it was key to identify patients at high risk of a complicated disease course at the earliest opportunity, to reduce bowel damage. Patients with perianal disease, stricturing or penetrating behaviour, or severe growth retardation should be considered for up-front anti-tumour necrosis factor [TNF] agents in combination with an immunomodulator. Therapeutic drug monitoring to guide treatment changes is recommended over empirically escalating anti-TNF dose or switching therapies. Patients with low-risk luminal CD should be induced with exclusive enteral nutrition [EEN], or with corticosteroids when EEN is not an option, and require immunomodulator-based maintenance therapy. Favourable outcomes rely on close monitoring of treatment response, with timely adjustments in therapy when treatment targets are not met. Serial faecal calprotectin measurements or small bowel imaging [ultrasound or magnetic resonance enterography] are more reliable markers of treatment response than clinical scores alone. CONCLUSIONS We present state-of-the-art guidance on the medical treatment and long-term management of children and adolescents with CD.

Therapeutic Drug Monitoring-guided High-dose Infliximab for Infantile-onset Inflammatory Bowel Disease: A Case Series. J Pediatr Gastroenterol Nutr 2020; 71:516-520.

Abstract
Very early-onset inflammatory bowel disease (IBD) and specifically infantile-onset IBD patients, are characterized by high rates of extensive colonic involvement and decreased response rate to standard therapeutic regimens, including infliximab (IFX). We present a case series of 4 patients with infantile-onset IBD achieving clinical and biologic remission, after treatment with therapeutic drug monitoring (TDM)-guided accelerated high-dose IFX therapy. All patients were treated with accelerated high-dose IFX induction of up to 22 mg/kg. In 3 of these patients, accelerated high-dose IFX was used following failure of intensified standard dose induction. All patients achieved remission following re-induction.We suggest that children with infantile-onset IBD may require a TDM-guided accelerated high-dose IFX induction and maintenance treatment in order to achieve and maintain remission. Personalized approach in these patients is essential in order to prevent underdosing and to avoid inappropriate interpretation of treatment failure.

Abstract
BACKGROUND/AIMS The measurement of infliximab trough levels (IFX-TLs) in patients with inflammatory bowel disease (IBD) is performed to optimize treatment. However, the association between the development of adverse events (AEs) and IFX-TLs has not been sufficiently studied thus far. To investigate the possible association of IFX-TLs with AEs in Greek patients with IBD receiving maintenance treatment with IFX. METHODS A retrospective analysis of the registry data of the Gastroenterology Department of the University Hospital of Heraklion, from IBD patients with at least one available IFX-TL measurement during the years 2016 to 2017 was conducted. AEs reported 4 months before and 4 months after the measured IFX-TLs were recorded. The IFX-TLs of patients with or without AEs were compared. RESULTS Of a total of 83 IBD patients (61 Crohn's disease [73%]; 52 men [63%]; mean age ± standard deviation, 43.3 ± 16.0 years), 147 measurements of IFX-TLs were available (median 4.69 μg/ mL [1.32-9.16]), and 99 AEs (67.3%, 14 severe) were registered. The median IFX-TL of patients with AEs was 5.79 μg/mL (1.36- 10.25), higher than the median IFX-TL of patients without AEs (3.40 μg/mL [1.30-5.92]), but the difference was not significant (P= 0.97). The presence of infections or dermatologic reactions was not correlated with IFX-TLs. There was no difference in the prevalence of the total AEs (66.7% vs. 73.3%, P= 0.77) or in the analysis of AEs by group between patients with IFX-TLs ≥ 15 μg/ mL and patients with IFX-TLs < 15 μg/mL. CONCLUSIONS IFX-TLs are not significantly associated with the development of AEs in IBD patients receiving maintenance treatment with IFX.

Abstract
Infliximab (IFX), as a drug of first-line therapy, can alter the natural progression of Crohn’s disease (CD), promote mucosal healing and reduce complications, hospitalizations, and the incidence of surgery. Perianal fistulas are responsible for the refractoriness of CD and represent a more aggressive disease. IFX has been demonstrated as the most effective drug for the treatment of perianal fistulizing CD. Unfortunately, a significant proportion of patients only partially respond to IFX, and optimization of the therapeutic strategy may increase clinical remission. There is a significant association between serum drug concentrations and the rates of fistula healing. Higher IFX levels during induction are associated with a complete fistula response in these patients. Given the apparent relapse of perianal fistulizing CD, maintenance therapy with IFX over a longer period seems to be more beneficial. It appears that patients without deep remission are at an increased risk of relapse after stopping anti-tumor necrosis factor agents. Thus, only patients in prolonged clinical remission should be considered for withdrawal of IFX treatment when biomarker and endoscopic remission is demonstrated, especially when the hyperintense signals of fistulas on T2-weighed images have disappeared on magnetic resonance imaging. Fundamentally, the optimal timing of IFX use is highly individualized and should be determined by a multidisciplinary team.

Abstract
BACKGROUND AND OBJECTIVES Vedolizumab has demonstrated efficacy and safety in patients with Crohn's disease [CD] and ulcerative colitis [UC]. Endoscopic outcome data are limited, especially in anti-tumour necrosis factor [TNF] naïve patients. The present study compared endoscopic outcome in anti-TNF naïve and exposed patients, and explored if this was affected by drug exposure. METHODS We retrospectively analysed all patients initiating vedolizumab at our tertiary referral centre since 2015. For UC, endoscopic improvement was defined as a Mayo endoscopic subscore ≤1 at week 14. For CD, endoscopic remission was defined as absence of ulcerations at week 22. Vedolizumab trough concentrations were measured at week 6, week 14 and during maintenance. RESULTS A total of 336 patients were identified [53.3% CD], 20% of them being anti-TNF naïve. Endoscopic improvement was achieved by 56.1% of UC patients and endoscopic remission by 39.1% of CD patients. Endoscopic outcomes were significantly better in anti-TNF naïve vs exposed patients [all: 67.2% vs 42.0%, p = 0.0002; UC: 74.4% vs 50.0%, p = 0.02; CD: 57.1% vs 35.8%, p = 0.03]. Achievement of endoscopic end points significantly impacted long-term treatment continuation [p = 9.7 × 10-13]. A better endoscopic outcome was associated with significantly higher drug exposure in both CD and UC. CONCLUSIONS The results of this observational, single-centre real-life study suggest that vedolizumab may induce endoscopic remission in both CD and UC. Although anti-TNF naïve patients had a significantly better outcome, 42% of anti-TNF exposed patients still benefited endoscopically. A clear exposure-endoscopic response relationship exists, but not all patients will benefit from treatment intensification. Hence, predictive biomarkers remain necessary.

Abstract
BACKGROUND Clinical application of therapeutic drug monitoring (TDM) to optimise anti-TNF therapies in patients with IBD depends upon target ranges. AIMS To review methodology used to determine therapeutic ranges and critically compare and contrast its application to infliximab and adalimumab. METHODS A systematic review was performed, and relevant literature was summarised and critically examined. RESULTS Upper limits of the therapeutic range are determined by toxicity, a plateau response and cost. Lower limits are determined by optimal concentration on the target of action in vitro and/or in vivo, or by correlation of drug levels with clinical efficacy using area-under-receiver-operator-curve (AUROC) analysis. In 43 studies, there were huge variations in time at which infliximab and adalimumab levels were measured, the end-points used (clinical remission to mucosal healing), the clinical setting (active disease vs maintenance phase) and the reason for TDM (proactive vs reactive). In the maintenance phase for infliximab, lower trough limits 2.8-5.7 µg/mL are reported depending upon end-points used, with consistent AUROC 0.68-0.77. Adalimumab TDM targets are even less consistent with a lower limit 5.9-11.8 µg/mL (AUROC 0.66-0.83) in some studies, but no cut-off can be identified that is significantly associated with outcome in others, related to inherent pharmacokinetic and pharmacodynamic differences, and heterogeneity of study design. CONCLUSIONS Evidence for exposure-response relationship is stronger for infliximab than adalimumab. Due to heterogeneity in settings for drug level measurements, therapeutic ranges vary. These factors need to be taken into account when interpreting the evidence and extending this to therapeutic strategies for IBD patients.

Abstract
Infliximab (IFX) is administered intravenously using weight-based dosing (5 mg/kg) in inflammatory bowel disease (IBD) patients. Our hypothesis is that especially young children need a more intensive treatment regimen than the current weight-based dose administration. We aimed to assess IFX pharmacokinetics (PK), based on existing therapeutic drug monitoring (TDM) data in IBD patients < 10 years. TDM data were collected retrospectively in 14 centres. Children treated with IFX were included if IFX was started as IBD treatment at age < 10 years (young patients, YP) and PK data were available. Older IBD patients aged 10-18 years were used as controls (older patients, OP). Two hundred and fifteen paediatric inflammatory bowel disease (PIBD) patients were eligible for the study (110 < 10 year; 105 ≥ 10 years). Median age was 8.3 years (IQR 6.9-8.9) in YP compared with 14.3 years (IQR 12.8-15.6) in OP at the start of IFX. At the start of maintenance treatment, 72% of YP had trough levels below therapeutic range (< 5.4 μg/mL). After 1 year of scheduled IFX maintenance treatment, YP required a significantly higher dose per 8 weeks compared with OP (YP; 9.0 mg/kg (IQR 5.0-12.9) vs. OP; 5.5 mg/kg (IQR 5.0-9.3); p < 0.001). The chance to develop antibodies to infliximab was relatively lower in OP than YP (0.329 (95% CI - 1.2 to - 1.01); p < 0.001), while the overall duration of response to IFX was not significantly different (after 2 years 53% (n = 29) in YP vs. 58% (n = 45) in OP; p = 0.56).Conclusion: Intensification of the induction scheme is suggested for PIBD patients aged < 10 years. What is Known? •Infliximab trough levels of paediatric IBD patients are influenced by several factors as dosing scheme, antibodies and inflammatory markers. •In 4.5-30% of the paediatric IBD patients, infliximab treatment was stopped within the first year. What is New? •The majority of young PIBD (< 10 years) have inadequate IFX trough levels at the start of maintenance treatment. •Young PIBD patients (< 10 years) were in need of a more intensive treatment regimen compared with older paediatric patients during 1 year of IFX treatment. •The chance to develop antibodies to infliximab was relatively higher in young PIBD patients (< 10 years).

Abstract
Introduction: Secondary loss of response to anti-tumor necrosis factor (TNF) therapy remains a challenge in the clinical management of inflammatory bowel disease (IBD) patients. A frequently observed reason for secondary loss of response to TNF blockers is inadequate drug exposure and sub-therapeutic serum drug concentrations. Areas covered: This review presents an overview of recent research on therapeutic drug monitoring (TDM)-based dosing with anti-TNF agents in IBD. The role of reactive and proactive TDM and different approaches on how to optimize anti-TNF treatment are discussed. Expert opinion: Due to variations within and between patients, the 'one size fits all' theory does not apply to all IBD patients receiving anti-TNF agents. Timing of TDM (i.e. reactive versus proactive) is a matter of debate. Both strategies might optimize anti-TNF treatment, although most trials did not show a clinical benefit compared to conventional dosing up to now. So-called dashboard systems might have an additive value in the optimization of anti-TNF treatment, since these tools enable clinicians to really personalize anti-TNF treatment.

Abstract
Background: The relationship between serum adalimumab concentrations and adverse events in patients with inflammatory bowel disease (IBD) is unknown. We aimed to determine whether patients with IBD using adalimumab are at increased risk of adverse events if they have higher adalimumab serum levels compared to those with lower adalimumab levels. Methods: This was a retrospective study of 191 IBD patients with at least one serum adalimumab level measurement available. The cohort was divided using a cutoff level of 10 mcg/mL. The primary outcome was the rate of overall adverse events between the two groups. Secondary outcomes included rate of infections, dermatologic reactions, injection-site reactions and other adverse events in both groups. Rates of discontinuation of adalimumab due to adverse events were evaluated. Multivariate logistic regression analysis was performed to evaluate the relationship between adalimumab levels and adverse events. Results: A total of 41 adverse events were reported in 191 patients in the overall cohort. Among 86 patients with higher adalimumab levels, 22 adverse events were reported, vs. 19 adverse events among 105 patients with lower adalimumab levels (25.6% vs. 18.1%, p = .21). Analysis according to adalimumab level tertiles also did not show significant differences in the rates of adverse events. A multivariate forward selection model also did not find higher odds of an adverse event in IBD patients with higher adalimumab levels compared to lower levels (OR 1.54, 95% CI 0.77-3.08). Conclusions: There does not appear to be a relationship between adalimumab exposure and risk of adverse events in IBD patients.

Abstract
PURPOSE OF REVIEW Crohn's disease management has changed significantly with increasing use of biologics. We review the recent literature on the clinical management of Crohn's disease and new approaches in selecting and optimizing therapy. RECENT FINDINGS Recent studies have addressed the efficacy of proactive anti-TNFα trough level monitoring, the efficacy of biosimilars, and the efficacy and immunogenicity of newer biologics including anti-integrin therapy and anti-IL12/23 therapy. Optimizing anti-TNFα therapy according to trough concentrations correlates with improved remission rates. Patients can be switched from the reference drug to a biosimilar, or vice versa, without a measurable change in efficacy, safety, or immunogenicity. Immunomodulators are effective in decreasing immunogenicity and boosting anti-TNFα drug level. The anti-integrin and anti-IL12/23 therapies are effective as induction and maintenance therapy with low immunogenicity and excellent safety profiles. Patients at high risk for post-operative recurrence should be started on a biologic therapy within 4 weeks post-op. Multiple biologic therapies are currently available for treatment of Crohn's disease including anti-TNFα therapy, anti-integrin therapy, and anti-IL12/23 therapy. The choice of first-line therapy should be based on individual risk-benefit analysis, route of administration, and patient preference. Patient with inadequate response should have their trough level checked and therapy optimized. Therapeutic prophylaxis for post-operative recurrence should be based on patient's risk factors for recurrence.

Optimised infliximab monotherapy is as effective as optimised combination therapy, but is associated with higher drug consumption in inflammatory bowel disease. Aliment Pharmacol Ther 2019; 49:880-889. [PMID: 30784100 DOI: 10.1111/apt.15179] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2018] [Revised: 10/01/2018] [Accepted: 01/16/2019] [Indexed: 12/11/2022]
Abstract
BACKGROUND Combination treatment with azathioprine for 6-12 months is the preferred strategy for starting infliximab due to improved pharmacokinetics. However, optimised infliximab monotherapy with proactive dose escalations in case of low trough levels is a safer but under-studied alternative. AIM To compare the clinical success and infliximab consumption of combination vs optimised monotherapy strategies. METHODS We studied the clinical success and infliximab consumption of both strategies in 149 patients (94 Crohn's disease; 55 ulcerative colitis) starting infliximab and undergoing intensive drug monitoring assisted treatment optimisation. RESULTS The drug retention rates were similar for optimised monotherapy and combination treatment after induction (96% vs 97%, P = 0.73), after the first year (90% vs 83%, P = 0.23) and at the end of follow-up (74% vs 75%, P = 0.968). Similarly, no differences were observed for steroid use at year 1 (5% vs 14%, P = 0.08) or mucosal healing at the end of follow-up (64% vs 67%, P = 0.8). Higher infliximab consumption (7.6 mg/kg q8 weeks [interquartile range (IQR): 5.9-10.3] vs 6.4 mg/kg q8 weeks [IQR: 5.2-8.0], P = 0.019) combined with lower trough levels (1.7 µg/mL [IQR: 0.3-6.6] vs 5.0 µg/mL [2.5-8.7], P = 0.012) resulted in almost 3-fold higher drug-to-trough ratio (3.9 vs 1.5) in monotherapy compared to combination strategy at year 1. At the end of follow-up, when azathioprine had been discontinued for a median of 14 [IQR: 3-33] months, these differences disappeared. CONCLUSIONS In this study, optimised infliximab monotherapy was as clinically effective as combination therapy but was associated with significantly higher infliximab consumption. The infliximab-sparing effect disappeared after azathioprine withdrawal.

Mucosal IL13RA2 expression predicts nonresponse to anti-TNF therapy in Crohn's disease. Aliment Pharmacol Ther 2019; 49:572-581. [PMID: 30663072 PMCID: PMC6849553 DOI: 10.1111/apt.15126] [Citation(s) in RCA: 42] [Impact Index Per Article: 8.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2018] [Revised: 11/04/2018] [Accepted: 12/13/2018] [Indexed: 12/19/2022]
Abstract
BACKGROUND Ileocolonic expression of IL13RA2 has been identified as a predictive marker for nonresponsiveness to infliximab (IFX) in patients with Crohn's disease (CD). AIM To validate the IL13RA2 biomarker, study its anti-TNF specificity and get a better understanding of the underlying biology driving its expression. METHODS IL13RA2 mucosal expression was studied in a cohort of adalimumab and vedolizumab treated patients. To identify the upstream regulators of anti-TNF nonresponsiveness, weighted gene co-expression network analysis was applied on publicly available microarray data of IFX-treated patients. Selected serum proteins, including TNF, were measured prior to first IFX exposure and compared between healers and nonhealers. RESULTS Increased mucosal IL13RA2 expression prior to start of biological therapy was predictive for anti-TNF nonresponsiveness specifically (AUROC, area under the curve = 0.90, P < 0.001 in anti-TNF vs AUROC = 0.63, P = 0.30 in vedolizumab treated patients). In baseline biopsies, TNF-driven pathways were significantly enriched in future anti-TNF nonhealers (P = 5.0 × 10-34 ). We found an increased baseline mucosal TNF burden in nonhealers (P = 0.02), and TNF mRNA correlated significantly with IL13RA2 expression (ρ = 0.55, P = 0.02). Baseline serum TNF levels were significantly lower in nonhealers (P = 0.04), and correlated inversely with IFX serum induction levels (r = -0.45, P = 0.002 at week 6). CONCLUSIONS Increased mucosal IL13RA2 expression is associated with an increased mucosal TNF burden in CD patients. In view of its specificity for prediction of anti-TNF therapy resistance, mucosal IL13RA2 expression is a potential biomarker for therapy selection and/or for the need of increased anti-TNF drug dosing.

Predictors of relapse following infliximab de-escalation in patients with inflammatory bowel disease: the value of a strategy based on therapeutic drug monitoring. Aliment Pharmacol Ther 2019; 49:147-154. [PMID: 30589970 DOI: 10.1111/apt.15046] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2018] [Revised: 09/11/2018] [Accepted: 10/09/2018] [Indexed: 12/27/2022]
Abstract
BACKGROUND There are limited data concerning infliximab drug monitoring during de-escalation of the treatment of inflammatory bowel disease (IBD). AIM To define the rate and the predictors of relapse following infliximab de-escalation in IBD patients in remission. METHODS All IBD patients at a single referral centre in clinical and biological remission and in whom the dose of infliximab had been de-escalated were included. Patients in remission with a high trough level of infliximab (>7 mg/L) were considered to be trough level-based de-escalation patients. The data were retrieved from a prospective IBD database. Actuarial analysis was performed for statistical purposes. RESULTS A total of 146 de-escalations were performed in 96 patients (Crohn's disease/ulcerative colitis: 68%/32%); 54 (37%) were based on clinical remission only, and 92 (63%) were based on clinical remission associated with a trough level above 7 mg/L. The cumulative probabilities of relapse following infliximab de-escalation were 16% and 47% at 1 and 2 years, respectively. Ulcerative colitis was associated with an increased risk of relapse (HR = 3.2, P = 0.005). Conversely, combination therapy at infliximab initiation (HR = 0.39, P = 0.0110) and trough level-based de-escalation were associated with decreased risk of relapse (HR = 0.45, P = 0.024). Trough levels before and after de-escalation were well correlated; a decrease by half was observed following a 2-week interval increase or a half-dose decrease. CONCLUSION The use of trough levels to assess the feasibility of dose de-escalation seems to be a prerequisite for decreasing the risk of relapse.
