The striking proliferation of connective tissue in Duchenne muscular dystrophy is attributed, besides other components of the extracellular matrix, to an increase of endomysial and perimysial type III and type I collagen. We investigated if muscle fibrosis correlates to an increased serum concentration of procollagen I or III. Therefore, we measured the serum levels of carboxyterminal propeptide of type I procollagen, aminoterminal propeptide of type III procollagen and laminin P1 in 20 boys with progressive muscular dystrophy (16 definite Duchenne muscular dystrophy, 2 suspected of Duchenne muscular dystrophy, 2 Becker muscular dystrophy). In contrast to collagen I and III the expression of laminin in the basement membrane is known to be normal in Duchenne muscular dystrophy. There was no significant alteration of serum concentration of procollagen III N-peptide, procollagen I C-peptide and laminin P1 in boys with Duchenne muscular dystrophy. Measuring these parameters is not useful for investigating the extent of muscle fibrosis or for monitoring the effect of therapeutic trials such as steroid treatment.

UI	MeSH Term	Description	Entries
D007797	Laminin	Large, noncollagenous glycoprotein with antigenic properties. It is localized in the basement membrane lamina lucida and functions to bind epithelial cells to the basement membrane. Evidence suggests that the protein plays a role in tumor invasion.	Merosin,Glycoprotein GP-2,Laminin M,Laminin M Chain,Chain, Laminin M,Glycoprotein GP 2,M Chain, Laminin
