THE FAECAL MARKER OF CROHN`S DISEASE
Research aim: to study the diagnostic amount of faecal stoolproctine in revealing Crohn`s disease. During the research have been examined 14 patients, suffering from Crohn`s disease and 137 patients without any inflammatory or oncologic bowels pathology. It has been ascertained, that the faecal stoolproctine exceeds the immunochemical test, which revels latent blood in stool, also S-reactive albumen and erythrocyte sedimentation rate in the diagnostic amount (ППК: 0,94, СО: 0,05; ППК: 0,73, СО: 0,08; ППК: 0,71, СО: 0,09; ППК: 0,72, СО: 0,08 accordingly, р < 0,05). The marker sensitivity in revealing Crohn`s disease at the cutting off point of 75,18 mkg/g was 92,31 % (95 % ДИ: 63,90-98,70) and specifity - 95,49 % (95% ДИ: 90,40-98,30).
