    Notes: 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.

    Notes: Abstract We investigated the effect of the menopause and postmenopausal hormone replacement therapy on the serum concentration of carboxyterminal propeptide of type I procollagen (PICP), which is a biochemical marker of type I collagen synthesis. A group of 124 healthy postmenopausal women, aged 45–53 years, had about 20% higher serum PICP than did a group of 40 healthy premenopausal women aged 35–52 years (114±35 µg/1 vs. 95±26 µg/l (mean ± SD);p=0.002). The 124 postmenopausal women were also participating in a double-masked longitudinal study with two placebo groups and four different hormone replacement therapy groups. The four hormone regimens resulted in similar responses in serum PICP. Compared with placebo, 1 year of treatment with any of the four hormone replacement therapies significantly decreased serum PICP to premenopausal levels. We conclude that the formation of type I collagen is increased shortly after the menopause and that hormone replacement therapy reverses this increase.

    Non-responders to hormone replacement therapy for the prevention of postmenopausal bone loss: Do they exist? (1994)

    Notes: Abstract Hormone replacement therapy (HRT) prevents postmenopausal bone loss, but the prevalence of non-responders in healthy early postmenopausal women is not known. In order to study this, we reviewed data from three published studies, each carried out in a randomized, placebo-controlled, longitudinal design over 2 year, that used seven hormone replacement therapies. Bone mineral content (BMC) was measured in the distal forearm by single photon absorptiometry. A mathematical model for elimination of measurement errors was applied to published BMC data. After this correction, we found that only 1.2% of early healthy postmenopausal women who are receiving HRT in conventional doses will lose more than 1% of forearm BMC per year. In conclusion, most, if not all, healthy early postmenopausal women who might need HRT against loss of bone will respond positively in forearm BMC to such therapy.

    Serum concentration of vitamin D metabolites in rheumatoid arthritis (1987)

    Notes: Summary One-hundred and two patients with rheumatoid arthritis (RA) were studied. They were divided into three groups according to treatment with gold salts, penicillamine or glucocorticoids. Blood samples were drawn between November and January and four different metabolites of vitamin D (25(OH)D3, 24,25 (OH)2D3, 25,26 (OH)2D and 1,25 (OH)2D) were measured and compared to values from normal subjects. The mean serum concentrations of 25(OH)D3 in all three patient groups were significantly lower than those of the controls (p〈0.01–0.001). The mean serum concentrations of 24,25 (OH)2D3 and 25,26 (OH)2D were not significantly different from the control values, whereas 1,25 (OH)2D concentrations were significantly lower in the penicillamine and steroid groups (p〈0.05–0.01). When patients were stratified according to functional classes, we found a significant inverse relation between serum concentrations of 25(OH) D3, 24,25(OH)2D3, 25,26(OH)2D and the functional class, but not between 1,25(OH)2D and the functional class. We conclude that the decreased serum 25(OH)D3 concentration found in patients with RA is likely to be caused by decreased exposure to sunlight due to decreased activity, and thus is a result of the disease rather than a pathogenetic factor. Whether the small decrease in serum 1,25(OH)2D is of clinical significance and related to the development of osteoporosis in patients with RA is probably doubtful.

    Prevalence of decreased bone mass in rheumatoid arthritis. Relation to anti-inflammatory treatment (1984)

    Notes: Summary The bone mineral content (BMC) in both forearms (highly correlated to total body calcium) was measured by photon absorptiometry in a representative sample of rheumatoid arthritis outpatients comprising 129 patients treated with either gold salts (n=29), penicillamine (n=61), prednisone (n=24), or other anti-RA drugs (n=15). The mean BMC value was 84% of normal (p〈0.001) with the lowest mean value in the group treated with prednisone (73% of normal). The patients as a group had hypocalcaemia (p〈0.001), raised serum alkaline phosphatase (p〈0.001), and normal urinary excretion rates of calcium and hydroxyproline. These results indicate that RA patients have disturbances in their calcium and bone metabolism.
