Can soy intake affect serum uric acid level? Pooled analysis from two 6-month randomized controlled trials among Chinese postmenopausal women with prediabetes or prehypertension

Background: Uric acid is one of natural antioxidants in human body. There have been several studies on the correlation between uric acid with oxidative stress and osteoporosis. However, the data are insufficient and results are controversial. In this regard, we determined the association between uric acid levels and bone mineral density (BMD) during the postmenopausal period. Methods: We analyzed data from 328 postmenopausal women (mean age, 57.3 ± 6.5 years; mean serum uric acid level, 4.6 ± 1.0 mg/dL). The participants were divided into three groups based on tertiles of the serum uric acid level. The participants receiving hormone replacement therapy (HRT), bisphosphonates, or lipid-lowering agents were included. Results: Blood urea nitrogen, serum creatinine, and serum triglyceride levels were significantly higher in the upper tertiles of uric acid levels. No significant difference was found in the mean uric acid levels between medication users and non-users. Each HRT regimen had a different mean serum uric acid level. A cross-sectional analysis showed no significant correlation between the serum uric acid levels and BMD in the spine and femoral neck (spine BMD: 1.050 ± 0.131, 1.060 ± 0.160, 1.084 ± 0.140, p = 0.22; femoral neck BMD: 0.837 ± 0.110, 0.849 ± 0.096, 0.863 ± 0.115, p = 0.28 for each tertile of uric acid). Longitudinal analysis of data from 186 women with follow-up examinations at a mean interval of 14.6 months also revealed no difference in reduction in both spine and femoral neck BMD between tertile groups of serum uric acid (the median BMD reduction for spine: −0.02, 0.01, −0.04, p = 0.95; the median BMD reduction for femoral neck: 0.008, 0.005, −0.003, p = 0.34). Conclusions: Serum uric acid level is not associated with BMD in postmenopausal women.

The Mean

Background: Hyperuricemia develops when serum uric acid level exceeds the normal value. Estrogen may influence the level of serum uric acid. Postmenopausal females have a remarkable reduction in its level, so serum estradiol is studied in relation to serum uric acid levels in pre and post-menopausal women. Objective: To find out the relationship of serum Estradiol with serum uric acid level in premenopausal and postmenopausal women in local population. Study Design: Case control study. Setting: This study was conducted in Lady Aitchison Hospital Lahore. Period: March 2017- August 2017. Material and Methods: 134 females were enrolled in total and were grouped in to two. Group A comprised of premenopausal and Group B included postmenopausal females. After complete history and general physical examination, 5 ml venous blood sample under aseptic measures was taken. Serum uric acid was measured by enzymatic and serum estradiol by Enzyme-linked immunosorbent assay method. Results: The mean age of pre and postmenopausal women was 32 and 57 ± 7 years, with significantly lower in premenopause. The mean serum E2 was 91.86 ± 26.71 mg/dL in premenopause and 22.04 ± 9.28 mg/dL in postmenopause, with significantly lower mean in postmenopause. Mean serum uric acid was statistically higher in postmenopause that was 6.04 ± 0.58 mg/dL, when compared to premenopause that was 4.22 ± 0.90 mg/dL. Conclusion: Serum uric acid levels increased due to decreased serum estradiol in postmenopausal women as compared to premenopausal women.
