Background:
Calprotectin, a marker of neutrophil activation, has been associated with a poor prognosis in alcohol-induced cirrhosis. The aims were to study concentrations of calprotectin in patients with various liver diseases, and to further investigate the prognostic value of calprotectin in cirrhosis.
Methods:
Plasma calprotectin concentrations were determined in 84 patients with alcohol-induced liver disease, 32 hepatitis B or C infected patients, 33 patients with liver disease of other aetiologies, 7 patients with combined aetiologies and in 24 patients with malignant disease. Thirty healthy individuals were included as controls. Ascites calprotectin concentrations were determined in patients with ascites (n = 75). Follow-up for survival was performed after a median observation period of 10 months.
Results:
Increased plasma and ascites calprotectin concentrations were observed in malignant disease compared to non-malignant disease (P < 0.0001). Plasma calprotectin concentrations were low in viral liver disease compared to patients with non-viral liver disease (P = 0.02) and to controls (P = 0.0002). Plasma calprotectin (>median) was a highly significant marker of poor survival in alcohol-induced cirrhosis (P = 0.001), but was of no prognostic value in non-alcohol-induced cirrhosis (P = 0.88). In decompensated cirrhosis high (>upper quartile) ascites calprotectin concentrations were associated with an increased mortality (P = 0.002), as were high (>median) plasma calprotectin levels (P = 0.009).
Conclusion:
The prognostic importance of calprotectin in alcohol-induced cirrhosis is confirmed and demonstrated as specific for alcohol-induced liver disease. Low calprotectin levels are indicated in viral liver disease, and an association between high ascites calprotectin levels and malignant ascites was observed.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
