title: [The clinical value of laminin determination in advanced liver cirrhosis].
abstract: OBJECTIVE
  To test prospectively whether serum laminin levels, which is taken to indicate portal hypertension, can predict the occurrence of severe complications in advanced cirrhosis of the liver.
  
  
  METHODS
  In 38 patients (21 men, 17 women; mean age 55.6 +/- 13.4 years) with liver fibrosis (n = 4) or liver cirrhosis (n = 34) serum laminin was measured by a commercially available radioimmunoassay (Behring, Marburg). The severity of liver cirrhosis was graded according to the Child-Pugh-Christensen criteria. Portal hypertension was assessed by standard endoscopic methods and portal-vein duplex sonography. Within a mean observation period of 12.5 +/- 3.5 months, the following were used as signs of severe clinical complications of liver cirrhosis: stages III and IV of hepatic coma, treatment-refractory ascites, portal vein thrombosis and death due to multi-organ failure. Acute bleeding from oesophageal varices was confirmed by emergency endoscopy.
  
  
  RESULTS
  At laminin concentrations of 3.25 +/- 0.20 U/ml there was a highly significant correlation (P < 0.001) with complications of liver cirrhosis. Using 2.6 U/ml as the critical level, the occurrence of severe complications had a positive predictive value of 0.80 with a sensitivity and specificity of 0.71 and 0.86 respectively. This means that a patient who, at the beginning of the study period, had a raised laminin concentration, had a relative risk of 2.65 (1.41-4.97) for later severe complications.
  
  
  CONCLUSIONS
  Serum laminin concentration has a diagnostic efficiency of 0.79 as a prognostic indicator and can thus serve as a valuable addition to the Child-Pugh-Christensen classification of liver cirrhosis.
