| Popis: | The use of inhaled corticosteroids in bronchial asthma has widened, but there is a lack of data on their effect on bone collagen synthesis and degradation. This paper reports the effect of three dose levels (200, 1000 and 2000 micrograms day-1, 3 weeks each) of inhaled beclomethasone on specific characteristics of bone collagen metabolism in seven postmenopausal women with new asthma without any previous corticosteroid therapy. Serum aminoterminal (PINP) propeptide of human type I procollagen was seen, after an initial increase, to decrease significantly (from 42.2 to 35.5 micrograms l-1, P = 0.001) with the higher doses of inhaled beclomethasone, but no statistical change was found in the carboxyterminal propeptide (PICP) or type I collagen crosslinked telopeptide (ICTP). This data shows that type I collagen synthesis may be disturbed when using high-dose inhaled corticosteroids. However, further studies are needed to assess the effects of inhaled beclomethasone on the ability of the osteoblasts to form bone matrix, and on the density of bone during a longer treatment period with inhaled corticosteroids. |
