El test de sang oculta en femta immunol\u00f2gic<\/strong> (TSOFi)\n \u00e9s una prova no invasiva que detecta la pres\u00e8ncia de sang no visible en\n la femta per localitzar a temps p\u00f2lips en el c\u00f2lon que podrien derivar \nen un tumor maligne. No obstant aix\u00f2, no \u00e9s una prova perfecta i pot \ndonar un resultat fals positiu (un TSOFi positiu seguit d\u2019una \ncolonosc\u00f2pia sense lesions de risc o c\u00e0ncer colorectal), el que pot \ncomportar angoixa i realitzaci\u00f3 de colonosc\u00f2pies innecess\u00e0ries, amb els \nseus possibles riscos i uns costos addicionals per a la sanitat p\u00fablica i\n el pacient. <\/p>\n\n\n\n

Un\n nou estudi ha evidenciat que l\u2019\u00fas d\u2019inhibidors de la bomba de protons \n(IBP), un tipus de f\u00e0rmacs utilitzats per al bloqueig de la producci\u00f3 \nd\u2019\u00e0cid a l\u2019est\u00f3mac coneguts com a \u201cprazols\u201d, en el moment de fer-se el \nTSOFi,  augmenta la probabilitat d\u2019obtenir un resultat fals positiu en un 13%. <\/p>\n\n\n\n

Altres\n medicaments com els antiinflamatoris no estero\u00efdals, l’\u00e0cid \nacetilsalic\u00edlic, els antibi\u00f2tics i els laxants tamb\u00e9 s\u2019associen amb un \nfals resultat en el test. L\u2019efecte dels IBP \u00e9s independent del consum d\u2019altres f\u00e0rmacs. No\n obstant, prendre IBP de forma combinada amb antiinflamatoris augmenta \nmolt m\u00e9s la probabilitat de tenir un resultat fals positiu.   <\/p>\n\n\n\n

La recomanaci\u00f3 d\u2019evitar el consum dels IBP abans de fer-se el TSOFi podria reduir fins a un 3% de les colonosc\u00f2pies del programa de cribratge. Abans de poder fer aquesta recomanaci\u00f3, per\u00f2, seria necessari que estudis cl\u00ednics prospectius confirmessin aquests resultats
