title: Dupuytren's disease in type I diabetic subjects: investigation of biochemical markers of type III and I collagen.
abstract: OBJECTIVE
  To clarify whether biochemical markers of collagen type III and I metabolism show alterations in type I diabetic subjects with Dupuytren's disease (DD) compared to those without DD.
  
  
  METHODS
  DD was assessed in a total of 28 type I diabetic subjects, mean age 43.4 +/- 9.5 (SD) and duration of diabetes 25.2 +/- 9.7 years. Concentrations of aminoterminal propeptide of type III procollagen (PIIINP), carboxyterminal propeptide of type I procollagen (PICP) and carboxyterminal cross-linked telopeptide of type I collagen (ICTP) in serum and excretion of cross-linked N-telopeptides of type I collagen (NTX) and deoxypyridinoline crosslinks (DPyr) into urine were measured.
  
  
  RESULTS
  The prevalence of DD was 32% (9 of 28 diabetic subjects). Average serum ICTP was 2.7 +/- 0.8 micrograms/l in subjects without DD and 3.6 +/- 1.2 micrograms/l with DD (p = 0.0276). No significant association between other collagen markers and DD was found. The reference intervals of PIIINP and ICTP were exceeded only in 1 and 2 subjects, respectively, and they both had DD.
  
  
  CONCLUSIONS
  The degradation of type I collagen might be increased in diabetic subjects with DD. The overall implication was that synthesis or degradation of type III and I collagen in diabetic subjects with DD did not differ enough from those without DD to reflect changes in the biochemical markers of type III and I collagen.
