          Abstract

          Resumen Introducción: El fracaso de la terapia con biológicos en la enfermedad inflamatoria intestinal (EII) es un problema común. La monitorización farmacocinética es una herramienta que podría permitir optimizar estos tratamientos mediante la individualización de la posología en los diferentes escenarios clínicos. Objetivo: Describir las determinaciones de concentraciones séricas de infliximab y adalimumab en pacientes con EII y evaluar el impacto de las recomendaciones farmacocinéticas en la toma de decisiones clínicas y la evolución de los pacientes. Métodos: Estudio trasversal observacional retrospectivo de dos años de duración (2017-2018) de las determinaciones de inhibidores del factor de necrosis tumoral (anti-TNF) realizadas en pacientes del Servicio de Medicina Digestiva de un hospital general. Resultados: Se realizaron 133 determinaciones correspondientes a 66 sujetos (38% tratados con adalimumab; 62% infliximab). El principal motivo de monitorización (>55%) fue la presencia de enfermedad activa. Más de la mitad de los pacientes tenían concentraciones fuera del intervalo terapéutico (el 51% de adalimumab y 37% de infliximab presentaban una exposición subóptima). La recomendación de mantener la pauta posológica previa se propuso en <40% de los informes farmacocinéticos, siendo el grado de aceptación de la recomendación superior al 80% en todos los casos. Los datos analíticos de inflamación se redujeron tras la monitorización sin mostrar significación estadística en todos los casos. Conclusión: La mayoría de pacientes con EII tratados con anti-TNF presentan concentraciones de fármaco inadecuadas. La monitorización ha demostrado ser una herramienta útil para guiar la toma de decisiones terapéuticas y podría contribuir en la mejora de los parámetros clínicos de estos pacientes.

          Abstract Introduction: The failure of biologic therapy in inflammatory bowel disease (IBD) is a common problem. The pharmacokinetic monitoring is a useful tool that allows to optimize these treatments. Objective: To describe the pharmacokinetic determinations of plasma concentrations of infliximab and adalimumab in patients with IBD and evaluate its impact on clinical decision. Method: Retrospective, observational study of two years duration (2017-2018) of the tumor necrosis factor (anti-TNF) inhibitor determinations performed in patients of the Digestive Service of a general hospital. Results: A total of 133 determinations were obtained about 66 subjects (38% adalimumab, 62% infliximab). The main reason (>55%) of the request for monitoring was the presence of active disease. More than half of the patients had concentrations outside the therapeutic range (51% of patients with adalimumab and 37% of those with infliximab had plasma levels below the lower range considered suboptimal). The maintenance of the previous dosage was recommended only in <40% of the monitoring and the degree of acceptance of the interventions were more than 80% in all cases. The analytical data of inflammation were reduced after monitoring without showing statistical significance in all cases. Conclusion: Standard anti-TNF regimen was not adequate to obtain range concentrations in more than half of analyzed cases. Monitoring has proven to be very useful in supporting clinical decision and it may promote an improvement in the clinical parameters of patients with IBD.

          British Society of Gastroenterology consensus guidelines on the management of inflammatory bowel disease in adults

          Ulcerative colitis and Crohn’s disease are the principal forms of inflammatory bowel disease. Both represent chronic inflammation of the gastrointestinal tract, which displays heterogeneity in inflammatory and symptomatic burden between patients and within individuals over time. Optimal management relies on understanding and tailoring evidence-based interventions by clinicians in partnership with patients. This guideline for management of inflammatory bowel disease in adults over 16 years of age was developed by Stakeholders representing UK physicians (British Society of Gastroenterology), surgeons (Association of Coloproctology of Great Britain and Ireland), specialist nurses (Royal College of Nursing), paediatricians (British Society of Paediatric Gastroenterology, Hepatology and Nutrition), dietitians (British Dietetic Association), radiologists (British Society of Gastrointestinal and Abdominal Radiology), general practitioners (Primary Care Society for Gastroenterology) and patients (Crohn’s and Colitis UK). A systematic review of 88 247 publications and a Delphi consensus process involving 81 multidisciplinary clinicians and patients was undertaken to develop 168 evidence- and expert opinion-based recommendations for pharmacological, non-pharmacological and surgical interventions, as well as optimal service delivery in the management of both ulcerative colitis and Crohn’s disease. Comprehensive up-to-date guidance is provided regarding indications for, initiation and monitoring of immunosuppressive therapies, nutrition interventions, pre-, peri- and postoperative management, as well as structure and function of the multidisciplinary team and integration between primary and secondary care. Twenty research priorities to inform future clinical management are presented, alongside objective measurement of priority importance, determined by 2379 electronic survey responses from individuals living with ulcerative colitis and Crohn’s disease, including patients, their families and friends.

            Human anti-tumor necrosis factor monoclonal antibody (adalimumab) in Crohn's disease: the CLASSIC-I trial.

            Tumor necrosis factor blockade has been shown to be an effective treatment strategy in Crohn's disease (CD). Adalimumab is a human immunoglobulin G1 (IgG(1)) monoclonal antibody targeting tumor necrosis factor (TNF). A randomized, double-blind, placebo-controlled, dose-ranging trial was performed to evaluate the efficacy of adalimumab induction therapy in patients with CD. A total of 299 patients with moderate to severe CD naive to anti-TNF therapy were randomized to receive subcutaneous injections at weeks 0 and 2 with adalimumab 40 mg/20 mg, 80 mg/40 mg, or 160 mg/80 mg or placebo. The primary endpoint was demonstration of a significant difference in the rates of remission at week 4 (defined as a Crohn's Disease Activity Index score <150 points) among the 80 mg/40 mg, 160 mg/80 mg, and placebo groups. The rates of remission at week 4 in the adalimumab 40 mg/20 mg, 80 mg/40 mg, and 160 mg/80 mg groups were 18% (P = .36), 24% (P = .06), and 36% (P = .001), respectively, and 12% in the placebo group. Adverse events occurred at similar frequencies in all 4 treatment groups except injection site reactions, which were more common in adalimumab-treated patients. Adalimumab was superior to placebo for induction of remission in patients with moderate to severe Crohn's disease naive to anti-TNF therapy. The optimal induction dosing regimen for adalimumab in this study was 160 mg at week 0 followed by 80 mg at week 2. Adalimumab was well tolerated.
