Effects of anti-osteoporosis therapy on plasma aldosterone and renin

Posted on 2020-06-03 - 12:08
Objective:

This study aimed to investigate the effect of anti-osteoporosis therapy on plasma aldosterone concentration (PAC), plasma renin concentration (PRC) and the aldosterone/renin ratio (ARR) in patients with postmenopausal osteoporosis.

Methods:

In 60 patients with postmenopausal osteoporosis, bone mineral density (BMD), PAC and PRC were measured before and after treatment with alendronate (70 mg/week, n=22) or recombinant human parathyroid hormone (20 μg/day, n=35) for 48 weeks.

Results:

PAC was negatively correlated with the T-score of lumbar spine BMD and femoral neck BMD (lumbar r=−0.386, p<0.01; femoral neck r=−0.262, p<0.05). With the improvement in lumbar BMD after anti-osteoporosis treatment (T-score −3.4±0.5 vs. –3.1 ±0.4, p<0.0001), PAC decreased from 182.8±53.2 to 143.7±68.6 pg/mL (p<0.0001), PRC increased from 7.8±11.6 to 39.2±50.0 μIU/mL (p<0.0001) and the ARR decreased from 74.8±75.2 to 13.1±17.1 pg/μIU (p<0.0001). At baseline, 58% (35/60) of the patients had an ARR >37 pg/μIU, and the proportion decreased to 8% (5/57) after treatment.

Conclusion:

Treatment with alendronate or parathyroid hormone causes decreased PAC and increased PRC, resulting in a decreased ARR in postmenopausal women with osteoporosis.
