title: Short-term effects of hormone therapy on serum C-reactive protein levels in postmenopausal women.
abstract: OBJECTIVE
  The aim of this study was to investigate the effects of tibolone and conjugated equine estrogens (CEEs) plus medroxyprogesterone acetate (MPA) (CEE + MPA) on levels of serum C-reactive protein (CRP), an independent risk factor for cardiovascular disorders, in postmenopausal women.
  
  
  METHODS
  In this prospective randomized study, we randomly assigned 58 healthy postmenopausal women to CEE (0.625 mg/day) plus MPA (2.5 mg/day) (CEE + MPA) or tibolone (2.5 mg/day). The serum levels of CRP at 3 months after starting treatment were compared with baseline values for both therapies.
  
  
  RESULTS
  After 3 months of treatment the median CRP levels increased by 29% in the CEE + MPA group and by 5% in the tibolone group. But, these changes did not have statistical significance (P=0.15, P=0.06, respectively).
  
  
  CONCLUSIONS
  Our findings show that neither tibolone nor CEE + MPA caused significant changes in serum CRP levels in postmenopausal women. The potential impact of hormone therapy on serum CRP levels should be investigated in ongoing clinical trials.
