As a selective estrogen receptor modulator (SERM), raloxifene is used in healthy
postmenopausal women to prevent bone loss and reduce fractures. However, the
benefit of raloxifene is uncertain in the treatment of osteoporosis among
patients with end-stage renal disease (ESRD) or those who require maintenance
dialysis. We assessed the safety and efficacy of raloxifene in this particular
population. Studies were selected from PubMed, Springer, CNKI (Chinese National
Knowledge Infrastructure) and Wanfang Database. Randomized controlled trials
(RCTs) and prospective studies with control/placebo groups were
included. Five studies were included with a total of 244 participants (121
patients in the raloxifene group and 123 patients in the placebo/control
group). The median duration of treatment was 12 months. The incidence rate of
side effects of raloxifene was 0/121 (0%). There was a
significant improvement of lumbar spine bone mineral density (BMD) levels in the
raloxifene group compared with the placebo group (MD: 33.88, 95% CI:
10.93, 56.84, p=0.004). There was no significant difference concerning
the improvement of femoral neck BMD (MD: 8.42, 95% CI: –10.21,
27.04, p=0.38), intact parathyroid hormone (iPTH) (MD: –12.62,
95% CI: –35.36, 10.13, p=0.28), calcium (MD: -0.08,
95% CI: –0.61, 0.44, p=0.76), phosphorus (MD: 0.18,
95% CI: –0.12, 0.48, p=0.23) or bone alkaline
phosphatase (BAP) (MD: –4.33, 95% CI: –14.44, 5.79,
p=0.40). Raloxifene seems to be effective in improving the lumbar spine
BMD in postmenopausal women with ESRD. More large RCTs are necessary to evaluate
the long-term safety of raloxifene in uremic patients.
