Assessment of the fibrogenetic activity in chronic pancreatitis. The role of circulating levels of extracellular matrix components.
Determination of circulating levels of extracellular matrix components has been proposed as a reliable method to assess the activity of fibrogenetic processes. Therefore, we aimed to analyze circulating levels of laminin, fibronectin, and procollagen III peptide (PIIIP) in patients with chronic pancreatitis (CP) and to correlate them with the morphological and functional stage, and duration of the disease. Thirty patients with CP and 18 healthy controls were studied. Serum PIIIP concentrations (RIA), but not fibronectin (RID) and laminin (RIA), were abnormally high in 8 patients with CP. No correlation was found between circulating levels of extracellular matrix components and both functional and morphological stage and duration of CP. Nevertheless, patients with elevated serum PIIIP levels tend to have a more advanced CP (morphological and functional changes) than those with normal levels after a similar duration of the disease. We hypothesize that whereas functional and morphological findings reflect the cumulative effect of chronic inflammation on the pancreas, serum PIIIP concentrations would reflect the activity of the fibrogenetic process within the gland at the time of sampling. The results shown in the present study may be considered a starting point for longitudinal studies that examine the relationship between serum PIIIP or other markers for fibrogenetic activity and evolution of CP.
