Short-term growth and collagen turnover in asthmatic adolescents treated with the inhaled glucocorticoid budesonide.
    Steroids, 1997, Volume: 62, Issue:10

    Short-term lower leg growth, the insulin-like growth factor axis, and collagen turnover were assessed in 16 adolescents with asthma during treatment with inhaled budesonide, 800 micrograms/d, from a pressurized metered dose inhaler with a volume spacer. The design was a randomized double blind, placebo-controlled two-period crossover trial with treatment periods of 4 weeks and a 1-week wash-out. Lower leg growth was assessed by knemometry. Serum levels of insulin-like growth factor-I, insulin-like growth factor-binding protein-3, and the following markers of collagen turnover were evaluated: Serum markers of type I collagen formation and degradation; the carboxy-terminal propeptide of type I procollagen and the carboxy terminal pyridinoline cross-linked telopeptide of type I procollagen (ICTP), the serum marker of type III collagen formation; the amino-terminal propeptide of type III procollagen (PIIINP) and the urinary concentrations of the type I collagen degradation products pyridinoline (PYD) and deoxypyridinoline (DPD) cross-links. Mean lower leg growth velocity was suppressed from 0.51 mm/week during placebo to 0.18 mm/week during budesonide treatment (p < 0.001). No statistically significant effects on insulin-like growth factor-1, insulin-like growth faster-binding protein-3, or carboxy-terminal propeptide of type I procollagen were observed. ICTP and PIIINP were reduced with 2.3 and 2.5 micrograms/liter (p < 0.001 and p < 0.001, respectively) during budesonide treatment, urinary concentrations of PYD and DPD with 32.9 nmol/mmol creatinine (p < 0.005) and 6.8 nmol/mmol creatinine (p < 0.005), respectively. Significant correlations between lower leg growth velocity and ICTP, PIIINP, PYD, and DPD during placebo (p < 0.01, p < 0.05, p < 0.01, and p < 0.01) and budesonide (p < 0.05, p < 0.05, p < 0.05, and p < 0.05) periods were found. Short term lower leg growth suppression in adolescents treated with inhaled budesonide, 800 micrograms/d, reflects suppression of type I and III collagen turnover.

Bone and collagen turnover during treatment with inhaled dry powder budesonide and beclomethasone dipropionate.
    Archives of disease in childhood, 1995, Volume: 73, Issue:6

    To assess bone and collagen turnover in asthmatic children treated with dry powder budesonide from the Turbuhaler and dry powder beclomethasone dipropionate from the Diskhaler in a dose of 800 micrograms/day.. Thirteen prepubertal children with asthma.. Open crossover study with two treatment periods and treatment free run-in and wash-out periods. All periods were of two weeks' duration. At day 14 in each period blood samples were taken for assessment of serum osteocalcin, the carboxyterminal propeptide of type I collagen (PICP), and the aminoterminal propeptide of type III collagen (PIIINP). At the same time urine was collected for assessment of creatinine corrected pyridinoline (uPYR/cr) and deoxypyridinoline (udPYR/cr) crosslinks.. Osteocalcin concentrations were not influenced by any of the treatments. During budesonide treatment mean (SEM) PICP was reduced by 18% (8%) (p = 0.03), PIIINP by 24% (3%) (p = 0.0002), uPYR/cr by 16% (6%) (p = 0.03), and udPYR/cr by 21% (13%) (p = 0.12). During treatment with beclomethasone dipropionate mean (SEM) PICP was reduced by 20% (6%) (p = 0.01), PIIINP by 36% (3%) (p = 0.0002), uPYR/cr by 18% (4%) (p = 0.004), and udPYR by 13% (5%) (p = 0.02). The suppressive effect of beclomethasone dipropionate on PIIINP was more marked than that of budesonide (p = 0.001).. Treatment with dry powder budesonide and beclomethasone dipropionate 800 micrograms/day is associated with suppression of bone and collagen turnover. The suppression seems to be more marked during treatment with beclomethasone dipropionate. Long term effects and effects of lower doses of budesonide and beclomethasone dipropionate on bone and collagen markers needs further study.
