CATALINA MIHAI, CRISTINA CIJEVSCHI PRELIPCEAN, MIHAELA DRANGA, OTILIA GAVRILESCU, ANCA CARDONEANU, CRISTINA LACATUSU, BOGDAN MIRCEA MIHAI CORRELATIONS BETWEEN INFLAMMATORY BIOMARKERS AND ACTIVITY IN INFLAMMATORY BOWEL DISEASES There is an increasing interest in non-invasive methods to assess gut inflammation. The data regarding the correlations between inflammatory markers and activity of inflammatory bowel disease (IBD) are still controversial. In the last years faecal calprotectin became the most widely used biomarker in diagnosis and monitoring the IBD activity. We prospectively studied the correlation between the serological inflammatory markers (platelets, erythrocyte sedimentation rate - ESR, fibrinogen, C Reactive Protein -CRP, ferritin, albumin), faecal calprotectin and severity of IBD in a tertiary referral centre in North-East Romania. Our study demonstrated that is a good correlation between serologic inflammatory markers (platelets, fibrinogen and ferritin, not ESR and albumin) and severity of IBD. CRP is a good marker in Crohn’s disease (CD) but not in ulcerative colitis (UC). Faecal calprotectin (FC) is the best inflammatory biomarker which correlates with activity both in UC and CD. Inflammatory biomarkers, especially FC are an important tool to evaluate patients with IBD.
