ROLE OF THE MEASUREMENT OF SERUM PROCOLLAGEN TYPE-III N-TERMINAL PEPTIDE IN THE EVALUATION OF LIVER-DISEASES

Serum N-terminal procollagen-III peptide (PIIIP) was measured in 151 patients with diverse liver diseases together with other clinical and laboratory data. Patients with cirrhosis had higher serum PIIIP than those without cirrhosis (P < 0.0001). Significant associations were found between PIIIP and many data characteristic of liver diseases, including alcohol markers. Serum PIIIP was also associated with portal hypertension (P = 0.0001), although such association was probably due to the fact that most patients with portal hypertension were cirrhotic patients. The predictive values of PIIIP in portal hypertension were too low to be clinically useful. No one single factor could be identified as responsible for the increase in PIIIP and the data suggest that the mechanism is multifactorial. Measurement of serum PIIIP has a limited clinical value in the evaluation of patients with diverse liver diseases.
