Abstract
Objective
The aim of the present study was to determine the effects of raloxifene on changes
in circulating levels of cytokines and chemokines in relation to changes in lipid
profiles and markers of inflammation in postmenopausal women.
Methods
Fifty-three postmenopausal women aged 45–65 years old were randomly assigned in open,
parallel-group fashion to a control group or raloxifene group. Twenty-six women received
oral administration of 60 mg raloxifene every day and 27 women did not receive any drugs for 12 months. Serum
cytokines levels were simultaneously measured using a multiplexed human cytokine assay.
Results
Serum IL-7 concentrations in women who received raloxifene were decreased significantly
(p = 0.014), and serum monocyte chemoattractant protein (MCP)-1 concentrations in women
who received raloxifene were decreased significantly (p = 0.0003) at 12 months. In the control group, serum levels of MCP-1 and IL-7 did not
show significant changes. There were significant differences (p = 0.032 and p = 0.0024, respectively) in percentage changes in IL-7 and MCP-1 in the control group
and in the raloxifene group. Levels of low-density lipoprotein cholesterol (LDL-C)
and E-selectin were decreased significantly in women who received raloxifene, but
the percentage changes in LDL-C and E-selectin over a period of 12 months were not
significantly correlated with percentage changes in IL-7 and MCP-1 over the same period.
Conclusion
Circulating levels of IL-7 and MCP-1 decrease in postmenopausal women who received
raloxifene.
