Brief Summary:

In this study, the investigators would like to analyze the bone mineral density (BMD) , bone turnover makers, and fracture prevention effects of denosumab in Japanese patients under clinical practice. The participants are treated in the investigators hospital, who are under severe osteoporotic condition.

The main objective of this study is to investigate effects of denosumab. The researchers also investigate the effects of Effects of previous osteoporotic therapy to denosumab treatment. In this study, the investigators analyse the determinants of subsequent BMD increase and fracture preventing effect by teriparatide.

Condition or disease Intervention/treatment

Drug Information available for: Denosumab

Intervention Details:
  • Drug: Denosumab
    every 6 month injection
    Other Name: Prolia

Primary Outcome Measures :
  1. BMD increase by denosumab in Japanese [ Time Frame: Up to 48 months ]
    The investigators evaluate BMD increase by denosmab in Japanese patients.

Secondary Outcome Measures :
  1. The determinants related to BMD increase and fracture prevention for denosumab treatment [ Time Frame: Up to 48 months ]
    The investigators evaluated lumbar and femoral neck BMD. The investigators evaluated baseline patients characteristics. The investigators will evaluate the relationship between BMD increase or fracture and patients characteristics using univariate and multivariate analysis.

  2. Effects of previous therapy to denosumab [ Time Frame: Up to 48 months ]
    The investigators evaluate effects of previous osteoporosis treatment to denosumab in BMD increase and bone turnover marker response using univariate and multivariate analysis.
