The Evidence for Efficacy of Osteoporosis Treatment in Men with Primary Osteoporosis : A Systematic Review and Meta-Analysis of Antiresorptive and Anabolic Treatment in Men

Abstract EN

Purpose.

Fragility fractures in men constitute a major worldwide public health problem with a life-time risk of 13%.

It cannot be directly inferred that antiosteoporotic drugs effective in women have the same effect in men.

Our aim was to appraise the existing evidence for efficacy of osteoporosis treatment in men.

Methods.

This study was a systematic review of the published literature on the clinical efficacy of medical osteoporosis therapy in the reduction of fracture risk in men (age > 50 years).

Studies included were randomised, placebo-controlled trials of men.

Results.

Five BMD studies of antiresorptive treatment were included.

All studies showed an increase in BMD, but there was only a nonsignificant trend in the reduction of clinical fractures.

Three BMD studies of anabolic treatment with teriparatide were also included.

These showed a significant mean increase in spine BMD and for vertebral fractures a non-significant trend towards a reduction was seen.

Conclusion.

The evidence of medical osteoporosis treatment in men is scant and inconclusive due to the lack of prospective RCT studies with fracture prevention as primary end point.

So far, all evidence is based on BMD increases in small RCT studies showing BMD increases comparable to those reported in postmenopausal women.
