RESUMEN
RESUMEN

Objetivo:

Evaluar la respuesta al tratamiento con anti-TNFs en pacientes con enfermedad inflamatoria intestinal. Materiales y

métodos:

Estudio prospectivo observacional realizado en el Servicio de Gastroenterología del Hospital Nacional Guillermo Almenara, de enero 2015 a agosto 2018.

Resultados:

Se evaluó 31 pacientes con enfermedad inflamatoria intestinal que recibían terapia de mantenimiento con Infliximab. Doce (38,7%) pacientes (3 con colitis ulcerativa y 9 con enfermedad de Crohn) presentaron pérdida de respuesta a partir de los 6 meses del inicio de la fase de mantenimiento 2 entre 6-12 meses, 4 entre 12-18 meses y 6 entre 18-24 meses. Como primera medida se duplicó la dosis (10 mg/kg) a los 12 pacientes, obteniendo respuesta en 6 (50%) luego de 12 semanas. De los 6 pacientes restantes, 4 cambiaron a Adalimumab, 1 paciente presentó cáncer de colon y 1 paciente presentó anafilaxia y sarcoidosis. De los pacientes que recibieron Adalimumab, 3 presentaron recidiva endoscópica (75%) a partir de los 6 meses y 1 no respondió a la terapia de inducción y fue sometido a colectomía (25%).

Conclusiones:

Aproximadamente un tercio de nuestros pacientes presentó pérdida de respuesta a terapia de mantenimiento con Infliximab. El escalamiento de dosis como rescate tuvo éxito en la mitad de los pacientes. El cambio a Adalimumab en pacientes con pérdida de respuesta a un primer fármaco anti-TNF no parece ser efectivo.
ABSTRACT
ABSTRACT

Objective:

To evaluate the response to treatment with anti-TNFs in patients with inflammatory bowel disease. Materials and

methods:

Prospective observational study conducted in the Gastroenterology service of the Guillermo Almenara National Hospital, from January 2015 to August 2018.

Results:

31 patients with inflammatory bowel disease who received maintenance therapy with Infliximab were evaluated. Twelve (38.7%) patients (3 with ulcerative colitis and 9 with Crohn's disease) presented loss of response after 6 months of the beginning of the maintenance phase 2 between 6-12 months, 4 between 12-18 months and 6 between 1824 months. As a first step, the dose was doubled (10 mg/kg) to the 12 patients, obtaining a response in 6 (50%) after 12 weeks. Of the remaining 6 patients, 4 switched to Adalimumab, 1 patient presented colon cancer and 1 patient presented anaphylaxis and sarcoidosis. Of the patients who received Adalimumab, 3 had endoscopic recurrence (75%) after 6 months and 1 did not respond to induction therapy and was subjected to colectomy (25%).

Conclusions:

Approximately one third of our patients presented loss of response to maintenance therapy with Infliximab. The dose escalation as a rescue therapy was successful in half of the patients. The change to Adalimumab in patients with loss of response to a first anti-TNF drug does not seem to be effective.
