Infections ACLF Death Different clinical courses of acutely decompensated cirrhosis Pre-ACLF Unstable decompensated cirrhosis Stable decompensated cirrhosis 0 90 180 270 360 Days Highlights Patients with acutely decompensated cirrhosis without ACLF develop 3 different clinical courses. Patients with pre-ACLF develop ACLF within 90 days and have high systemic inflammation and mortality. Patients with unstable decompensated cirrhosis suffer from complications of severe portal hypertension. Patients with stable decompensated cirrhosis have less frequent complications and lower 1-year mortality risk.

C-reactive protein on its own is a sensitive screening test for the presence of bacterial infections in cirrhosis and is also a useful marker to predict the likelihood of clinically significant bacterial infections in patients without overt infections.

Serological markers were useful in the differentiation between CD and UC in an Eastern European IBD cohort. Reactivity to microbial components was associated with disease phenotype and NOD2/CARD15 genotype, further supporting the role of altered microbial sensing in the pathogenesis of CD.

PAB autoantibodies in combination with ASCA or anti-glycan antibodies increase the sensitivity for detecting CD, especially isolated colonic CD. Antibody response to PAB was associated with complicated disease phenotype and extraintestinal manifestations in this Eastern European IBD cohort.
