Summary
In this second part, clinical aspects of connective tissue metabolism in the liver will be described and two main aspects considered. The first is the possibility to monitor the activity of fibrosis by the use of metabolites and enzymes of connective tissue metabolism. In recent studies the qualification for this purpose of enzymes such as procollagen prolyl hydroxylase and lysosomal N-Acetyl-β-glucosaminidase and the N-terminal peptide of procollagen type III has been tested. The serum activities or concentrations of these substances in patients with chronic active liver diseases increase in due relation to the histologically estimated activity of liver fibrosis.
The second aspect deals with therapeutic approaches to fibrosis in the liver by using connective tissue specific agents. So far none of the antifibrotic substances such as proline analogues, colchicine, lathyrogens and penicillamine has been used in longer-term antifibrotic treatment.
Zusammenfassung
Im zweiten Teil dieser Übersicht werden die klinischen Aspekte des Bindegewebsstoffwechsels in der fibrotischen Leber dargestellt. Besonders eingegangen wird auf die Möglichkeit, die Aktivität der Leberfibrose durch neuere Laborproben zur Erfassung von Enzymen und Metaboliten des Bindegewebsstoffwechsels zu verfolgen. Für diesen Zweck geeignet erscheinen die Enzyme Prokollagen-Prolyl-Hydroxylase, die lysosomale N-Acetyl-β-Glucosaminidase und das N-terminale Peptid vom Prokollagen Typ III. Die Aktivitäten bzw. Konzentrationen im Serum von Patienten mit chronisch aktiven Leberkrankheiten korrelieren gut mit der histologisch geschätzten Aktivität der Fibrose im punktierten Lebergewebe der gleichen Patienten. Weiterhin werden die therapeutischen Versuche zur Behandlung der Leberfibrose mit bindegewebsspezifischen Substanzen besprochen.
