Changes in circulating cytokine levels in midlife women with psychological symptoms with selective serotonin reuptake inhibitor and Japanese traditional medicine.

OBJECTIVE: The aim of the present study was to compare the effects on serum cytokine concentrations of paroxetine, a selective serotonin re-uptake inhibitor, and kamishoyosan, a Japanese traditional medicine, in midlife women with psychological symptoms. METHODS: Seventy-six women with psychological symptoms such as anxiety and mild depression as menopausal symptoms were enrolled in this study. Thirty-eight women received oral administration of 10mg paroxetine every day, and 38 women received oral administration of kamshoyosan every day for 6 months. Overall climacteric symptoms were assessed using Greene's climacteric scale. Serum levels of cytokines were measured using a multiplexed human cytokine assay. RESULTS: Greene's total scores in both women treated with paroxetine and in women treated with kamishoyosan decreased significantly. Percentage decreases in Greene's total, psychological and vasomotor scores during the 6-month period in the paroxetine group were significantly greater than those in the kamishoyosan group. Serum IL-6 concentration in women treated with paroxetine decreased significantly. Serum concentrations of IL-8, IL-10, macrophage inflammatory protein (MIP)-1beta and monocyte chemoattractant protein-1 in women treated with paroxetine decreased significantly. On the other hand, serum IL-6 concentration in women treated with kamishoyosan decreased significantly, but other serum concentrations did not change significantly. CONCLUSION: Decrease in IL-6 concentration may be involved in the mechanism of the actions of both paroxetine and kamishoyosan in women with psychological symptoms, and IL-6 may therefore be useful as a marker of treatment. The action of paroxetine may also be associated with decreases in IL-8, IL-10, MIP-1beta.

Circulating osteoprotegerin is associated with age and systolic blood pressure, but not with lipid profile or fasting glucose, in postmenopausal women.

OBJECTIVE: Osteoprotegerin (OPG), an inhibitor of osteoclastogenesis and osteoclast activation, has been reported to be linked to vascular biology. The aim of this study was to clarify the relationships between circulating OPG and the risk factors for vascular disorders in postmenopausal women. DESIGN: Eighty Japanese postmenopausal women were enrolled in this cross-sectional study. Clinical parameters (age, number of years since menopause, body mass index, systolic and diastolic blood pressure); serum concentrations of OPG, creatinine, calcium, and phosphorus; serum lipid profile; plasma glucose; and bone mineral density of the L2-4 vertebral bodies were determined for each woman. RESULTS: In rank-order correlation analysis, serum OPG concentrations had significant positive correlations with age (r = 0.29, P = 0.03), systolic blood pressure (r = 0.45, P < 0.01), diastolic blood pressure (r = 0.34, P < 0.01), and serum creatinine (r = 0.29, P = 0.04). Serum OPG concentration also had a marginally significant negative correlation with bone mineral density of the L2-4 vertebral bodies (r = -0.25, P = 0.06). However, serum OPG did not correlate with body mass index, serum lipid profile, or plasma glucose. The correlation of serum OPG with systolic blood pressure persisted after adjustment for both age and serum creatinine. CONCLUSIONS: These results suggest that increased circulating OPG in postmenopausal women is closely related to higher systolic blood pressure, which could cause atherosclerosis.
