The prognostic value of the aminoterminal propeptide of type III procollagen (P3NP) was investigated in 63 patients with primary biliary cirrhosis (PBC) followed for up to 87 months. No patient with an initially normal serum P3NP level died during the study; survival was significantly worse with increasing serum P3NP levels. Cox multivariate analysis confirmed that serum P3NP was an independent prognostic variable. Positive correlations were found between serum P3NP and histological stage, pericellular fibrosis, piecemeal necrosis, and serum concentrations of alanine aminotransferase and aspartate aminotransferase. Raised P3NP levels also correlated with the degree of cholestasis as evaluated by serum bilirubin, serum alkaline phosphatase, and copper binding protein deposition in the liver. Serum P3NP is of prognostic value because it reflects the major pathophysiological features of PBC.

The turnover of type III collagen, a major constituent of the myometrium and the uterine cervix, during pregnancy was evaluated by monitoring serum antigens related to the aminoterminal propeptide of type III procollagen. Their concentration increased markedly towards term in most uncomplicated pregnancies, while their size distribution throughout the pregnancy resembled that seen in the sera of normal healthy persons. In some patients, however, the level remained low, indicating interindividual variation in the release into serum and metabolism of the propeptide. There were no distinct changes during or immediately after vaginal delivery. Values exceeding the reference range for uncomplicated pregnancies were found during weeks 28-37 in patients with pre-eclampsia, essential hypertension, intrahepatic cholestasis of pregnancy or twin pregnancy. Thus, pregnancy should be taken into account when evaluating results of the serum assay for the aminopropeptide and the use of this assay as an indicator of pregnancy complications warrants further study.

This study was carried out to evaluated the role of the fibronectin (FN) in chronic liver diseases. For these reasons FN plasmatic concentration was assayed in patient with different degrees of chronic liver disease. For these reasons FN plasmatic concentration was assayed in patient with different degrees of chronic liver disease; the correlation between FN and the most common parameters of liver function was also evaluated. Moreover we also correlated FN plasma levels with laminin and the N-terminale peptide of type III procollagen, serum levels, that are through to be markers of fibrogenesis. 172 patients were studied: twenty-one patients suffering from chronic persistent hepatitis (CPH), 45 from chronic active hepatitis (CAH) and 106 from liver cirrhosis (LC). Last patients were also divided according the Child-Pugh's classification. Control group was composed of 74 healthy blood donors. Significant reduction of plasmatic levels of FN was found in the LC groups in comparison with control group (p < 0.0001) and also with CPH group (p < 0.01) and with CAH group (p < 0.0001). Lower values of FN were found in the LC group at advanced stage (Child-Pugh's B and C classes). In the group of CAH significant correlations with the parameters of cholestasis (GGT, APh, Tot. Bil. p < 0.005) were found, while in the group of LC significant correlations both with the parameters of synthesis (Alb. and Protr. time p < 0.01) and necrosis (AST/ALT p < 0.001). A negative correlation was also found between FN and spleen volume (p < 0.05). No correlation between FN and the parameters of fibrosis was found.(ABSTRACT TRUNCATED AT 250 WORDS)

The severity of pancreatic fibrosis, a characteristic feature of patients with chronic pancreatitis (CP), can be assessed only by direct histologic analysis of pancreatic tissue. Since serum levels of the amino-terminal type III procollagen propeptide (PIIIP) can reflect the degree of fibrogenic activity in several diseases associated with fibrosis, the current study was aimed at investigating whether PIIIP are increased in chronic pancreatitis, the relationship between PIIIP and pancreatic fibrogenic activity, and the influence of pancreatectomy, pancreatic exocrine function, and duration of disease on PIIIP levels. Serum PIIIP was measured in 18 patients with CP (15 without liver disease and three with cholestasis) and in 21 healthy controls. The effect of pancreatectomy on PIIIP was evaluated in seven patients, in whom PIIIP was measured immediately before and 2 months after surgery. Prolylhydroxylase (PHase) activity as an index of pancreatic fibrogenesis was evaluated in pancreatic tissue from 11 patients who had undergone subtotal pancreatectomy and from 11 organ donors. The bentiromide (BT)-PABA test as an index of exocrine pancreatic function was measured in all patients. PIIIP was significantly higher in patients who had or had not undergone pancreatectomy (17.3 +/- 4.0 and 25 +/- 11.4 ng/ml, respectively) than in controls (12.3 +/- 3.1 ng/ml) (p < 0.001). PIIIP decreased significantly after pancreatectomy (before, 32.0 +/- 9.3 ng/ml; after, 18.4 +/- 4.8 ng/ml; p = 0.005). PHase was significantly higher in patients (773 +/- 250 cpm/mg protein) than in controls (405 +/- 121 cpm/mg protein) (p < 0.001). PIIIP was correlated with pancreatic PHase (r = 0.7, p = 0.001) but not with BT-PABA or with the duration of the disease. In conclusion, serum PIIIP levels are increased in patients with CP and reflect the severity of pancreatic fibrogenic activity. No relationship between the serum PIIIP levels and the pancreatic exocrine function and duration of disease was found.
