title: Serum laminin levels offer only a little additional information in liver disease.
abstract: We have measured serum laminin, a marker of portal hypertension, in 151 patients with nonmalignant liver diseases, to evaluate its utility in cirrhosis and portal hypertension. There were abnormal serum levels in 43.1% of the patients as a whole and in 62.7% of the cirrhotics. Laminin showed a correlation with many laboratory tests, especially those that reflect liver insufficiency and alcohol intake. Cirrhotics had higher laminin levels than noncirrhotics (p < 0.0001); an association was also found with portal hypertension (p < 0.0001), but laminin was also increased in patients without portal hypertension. Our results suggest that liver dysfunction can also lead to abnormal laminin concentrations, probably through slower metabolization rate. Laminin serum concentrations reflect the severity of the liver disease, and are also a marker of alcohol consumption. Determination of laminin serum levels could play an adjunctive role with respect to other liver tests in the evaluation of these patients although the measure does not really provide more useful information.
