Abstract We investigated the effect of the menopause and postmenopausal hormone replacement therapy (HRT) on the serum concentration of carboxy-terminal pyridinoline cross-linked telopeptide of type I collagen (ICTP), a potential new biochemical marker of bone resorption. A group of 44 healthy postmenopausal women, aged 45–54 years, had about 19% higher serum ICTP than did a group of 42 healthy premenopausal women aged 35–50 years (3.6±0.8 µg/l v 3.0±0.7 µg/l (mean ±SD);p〈0.01), although there was a large overlap in the values. The 44 postmenopausal women also participated in a longitudinal clinical study, in which 20 received HRT and 24 received a placebo. Compared with the placebo group, those who received HRT had a significant (p〈0.05) decrease in ICTP of about 12% at the end of 1 year of treatment, but again there was considerable overlap in the values. The menopause-and HRT-induced changes in ICTP were less than those seen in serum osteocalcin, serum total alkaline phosphatase, and fasting urinary excretion of hydroxyproline, calcium, pyridinoline and deoxypyridinoline. We conclude that the menopause increases and HRT decreases ICTP, although these changes are less pronounced than those seen in other biochemical markers of bone turnover.
