Procollagen type 1 N-terminal propeptide and beta-collagen special sequence for the diagnosis and treatment of osteoporosis / 中国组织工程研究

ABSTRACT

BACKGROUND:Procolagen type 1 N-terminal propeptide (P1NP) and β-colagen special sequence(β-CrossLaps) are two bone metabolic markers that are closely related to osteoporosis. Combined detection of bone metabolic markers and bone mineral density is of clinical significance for the diagnosis of osteoporosis. Bone metabolic markers are ideal indicators to predict fractures, which can compensate for the lack of bone density test. OBJECTIVE:To introduce the application of bone metabolic markers in the monitoring of drug efficacy on the treatment of osteoporosis as wel as in the prediction of fracture risks in recent 20 years and to explore the clinical values of P1NP and β-CrossLaps to assess the therapeutic efficacy on osteoporosis and risks for osteoporotic fractures. METHODS:A computer-based search of CNKI and SCI databases were performed for relevant articles published from 2000 to 2014 using the keywords of “serum bone metabolic markers; osteoporosis; bone mineral density” in Chinese and English, respectively. Finaly, 44 articles meeting the inclusive criteria were reviewed. RESULTS AND CONCLUSION:This paper analyzes the source and detection mechanisms of P1NPand β-CrossLaps and then compares their advantages in the therapeutic effect assessment of osteoporosis. Serum bone metabolic markers cannot only reflect the dynamic changes of bone metabolism, but also have earlier changes than the bone mineral density. Both P1NPand β-CrossLaps are very important for assessing the early diagnosis of osteoporosis as wel as anti-osteoporosis drug efficacy.
