OBJECTIVES: To verify the diagnostic usefulness of soluble CD44 (sCD44) in liver diseases.
METHODS: We studied 142 subjects (90 male, 52 female): 14 had acute hepatitis (AH); 45, noncirrhotic chronic liver disease (CLD); 34, cirrhosis; 35 had extrahepatic diseases (EHD); and 14 were healthy controls. sCD44, soluble intercellular adhesion molecule-1 (slCAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) were measured immunoenzymatically.
RESULTS: Patients with AH or cirrhosis had higher sCD44 in comparison to CLD, EHD, and controls (p < 0.01). On univariate analysis, sCD44 was associated with sVCAM-1, sICAM-1, bilirubin, cholinesterase, aspartate aminotransferase, and alkaline phosphatase (p < 0.001). By stepwise discriminant analysis, a set of variables, including sCD44 and sVCAM-1, were entered into a model that allocated correctly 79% of observations (p < 0.0001). However, when adhesion molecules were excluded, the model could still allocate correctly 72% of observations.
CONCLUSION: Although sCD44 concentration increases during severe acute or chronic liver disease, its measurement adds little to the clinical information provided by traditional liver biochemistry.
