Serum Vitamin D and
Pyridinoline Cross-Linked Carboxyterminal Telopeptide of Type I Collagen in Patients with Ankylosing Spondylitis.
Urinary
pyridinoline cross-links in Ehlers-Danlos syndrome type VI.
The number of
pyridinoline cross-links and Hyl residues was expressed per collagenmolecule assuming 300 hydroxyproline residues per triple helix.
Comparison of free and peptide-bound
pyridinoline cross-links excretion in rheumatoid arthritis and osteoarthritis.
Such findings were then expressed in terms of peak ratios, with larger ratios reflecting an increase in the size and maturity of the crystals and an increase in the
pyridinoline cross-links in collagen, both of which reflect a deterioration in the quality of the bone matrix, Dr.
The only study investigating the influence of the perimenopausal status on urinary
pyridinoline cross-links excretion reported no differences between premenopausal women and perimenopausal women (36).
Radioimmunoassay for the

Urinary excretion of
pyridinoline cross-links correlates with bone turnover measured on iliac crest biopsy in patients with vertebrae osteoporosis.
The carboxy-terminal
pyridinoline cross-linked telopeptide of type I collagen in serum as a marker of bone resorption: the effect of nandrolone decanoate and hormone replacement therapy.
An initial immunoassay for
pyridinoline cross-links, using polyclonal antiserum that recognized the free form of both DPD and pyridinoline, revealed increased urinary concentrations of the crosslink compounds in metabolic osteopathies but did not provide tissue-specific information and therefore lacked clinical specificity (29).

pyridinoline cross-links excreted in human urine evaluated by chromatographic and immunoassay methods.
