Abstract:
Objective To observe the influence of long-term treatment with inhaled corticosteroid on biochemical bone indexes and bone mineral density (BMD) in children with asthma. Methods The design was a randomized, paralleled group study with 3 low dose regiments of 100, 200,300 micrograms of budesonide per day in 45 children with asthma aged 5-8 years old for 12 months. Before inhaled corticosteroid therapy and 6th,12th month,clinical effects were observed and lung function(FEV1) was measured; concentration of serum osteocalcin(OST),insulin-like growth factor-1(IGF-1),bony alkaline phosphatase (BALP) and urinary deoxypyridinolin: creatinine (DPD/Cr) were measured; BMD was examined by dual energy X-ray absorptiometry. Results Clinical evaluation was improved and there was significant increase in FEV1 of asthmatic children. The amount of serum OST was slightly higher,yet no significant compared with that of normal control group. There was significant increase of serum BALP in asthmatic children after treatment; there was significant increase in serum IGF-1 of patients group after treatment compared with in normal children at the same age group; there was significant decrease in urinary DPD/Cr after treatment.There was no significant decrease in BMD before and after treatment at the hip (neck of femur , trochanter of femur ,Ward′s triangle),the lumber area of the spine (L2-4) and forearm (ultradis, distal). Conclusion Long-term treatment with low does corticosteroid dose not restrictedly affect bone metabolism and BMD in children with asthma.
