Resumen

En la DDW 2010, acerca del tratamiento de la colitis ulcerosa se han presentado varios ensayos clínicos sobre nuevas terapias, con resultados negativos en su mayoría. Así, rituximab (anti CD 20) y MDX-1100 (inhibidor de quimiocinas) no mostraron eficacia, aunque es probable que en el futuro se prueben dosis más elevadas de ambos agentes. Tampoco se mostró útil un probiótico con capacidad de sintetizar y liberar interleucina 10 en la luz intestinal. Por el contrario, se comunicó otro ensayo con HMPL-004, extracto de una planta utilizada en medicina oriental, con resultados positivos en colitis levesmoderadas. Además de estos ensayos sobre nuevas terapias, también se presentaron datos acerca de las terapias actuales. En relación con los salicilatos, los resultados comunicados vuelven a enfatizar la importancia del cumplimiento en su eficacia y, en este sentido, del empleo en monodosis. En cuanto a su papel protector contra el cáncer de colon, los datos expuestos son contradictorios. Acerca de los agentes biológicos, estudios observacionales comunicados apoyan la eficacia de infliximab y datos controlados preliminares sugieren la utilidad de adalimumab. Sobre la aféresis leucocitaria, además de estudios observacionales españoles, se presentó un póster de un ensayo controlado y ciego, en el que se mostró eficaz para mantener la remisión de la colitis ulcerosa corticorrefractaria. Finalmente, sobre beclometasona se presentaron datos también españoles, retrospectivos y observacionales, que apoyan su utilidad.

Abstract

Several clinical trials on new therapies in ulcerative colitis were presented in Digestive Disease Week 2010, mostly with negative results. Thus, rituximab (anti CD 20) and MDX-1100 (a chemokine inhibitor) failed to show efficacy, although higher doses of both agents will probably be tested in the future. A probiotic able to synthesize and release interleukin-10 into the gut lumen also failed to prove useful. In contrast, HMPL-004, an extract from a herb used in Oriental medicine, was reported to have positive results in mild-to-moderate colitis. In addition to these data on new therapies, some other results segurion current therapies were also presented. The results communicated on salicylates once again emphasized the importance of compliance to achieve efficacy and the advantages of single-dose regimens in achieving this goal. The data reported on the protective role of salicylates against colon cancer were contradictory. Observational studies of biological agents supported the efficacy of infliximab and controlled preliminary data suggested the utility of adalimumab. Both Spanish observational studies and a poster presenting a blind, controlled trial showed the efficacy of leukocyte apheresis in maintaining remission in steroid-refractory ulcerative colitis. Finally, retrospective and observational Spanish data on beclomethasone supported the usefulness of this drug.
