Network meta-analysis of current drug options for the treatment of osteoporosis in men .
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2015;3(15):5 PLoS One. 2015 May 26;10(5):e012803213 studies with a total of 3647 men were included in this meta-analysis to analyze the effect of eight drugs (alfacalcidol, alendronate, ibandronate, risedronate, zoledronate, strontium ranelate, teriparatide, and parathyroid hormone) on bone mass density (BMD) in the lumbar spine (LS) and fracture incidence in males with osteoporosis. Network meta-analysis based on direct and indirect comparisons demonstrated that zoledronate had the greatest efficacy in increasing BMD in LS when compared to placebo, and teriparatide had the greatest efficacy in reducing fracture rate when compared to placebo.

لماذا كانت هناك حاجة لهذه الدراسة الآن؟
Osteoporosis is a common bone disease that results in decreased bone mass, and in turn significantly increases the risk of fracture. An improvement of bone mass density has been demonstrated to minimize the incidence of osteoporotic fractures. There have been a number of drugs which have been suggested to be efficacious in osteoporosis treatment, such as bisphosphonates (including alendronate, risedronate, ibandronate, and zoledronate), bone-anabolic drugs of parathyroid or teriparatide, strontium ranelate, and alfacalcidol, a vitamin D analog. Due to the wide range of drugs available, and conflicting results from many randomized controlled trials, the study sought to compare these options for primary treatment of osteoporosis.
ما هو سؤال البحث الرئيسي؟
Between available drug therapies for osteoporosis (alfacalcidol, alendronate, ibandronate, risedronate, zoledronate, strontium ranelate, teriparatide, and parathyroid hormone) what is the hierarchy of efficacy with respect to improvement in bone mineral density of the lumbar spine and reduction of fracture rate?
- Compared to placebo, effect on lumbar spine BMD from greatest to lowest was zoledronate (SMD 13.48 [95% CrI 11.88 to 15.08]), alendronate (11.04 [9.68 to 12.41]), teriparatide (20mcg) + risedronate (10.98 [8.55 to 13.48]), risedronate (10.33 [8.68 to 12.01]), teriparatide (20mcg) (9.33 [6.87 to 11.76]), strontium ranelate (8.88 [7.51 to 10.24]), ibandronate (5.49 [3.82 to 7.16]), parathyroid hormone (4.89 [3.12 to 6.62]) and alfacalcidol (3.42 [1.7 to 5.2]).
- With the exception of teriparatide (20mcg) + risedronate, zoledronate demonstrated a significantly greater effect size on LS BMD when compared to all other treatment options.
- Compared to placebo, significantly lower fracture rates were demonstrated with treatment with teriparatide (20mcg) (4.04 [1.36 to 8.49]), teriparatide (40mcg) (3.5 [1.14 to 8.34]), zoledronate (2.92 [1.29 to 5.62]), and risedronate (OR 2.51 [95%CrI 1.23 to 4.24]).
- Alfacalcidol was associated with significantly higher fracture rate than treatment with risedronate (7.66, 1.74 to 19.27), zoledronate (8.41, 2.12 to 20.03), strontium ranelate (5.21, 1.32 to 11.88), teriparatide (40mcg) (10.49, 1.83 to 30.47), or teriparatide (20mcg) (12.12, 2.17 to 33.84)
ما الذي يجب أن أتذكره أكثر؟
In osteoporosis treatment in men, zoledronate was associated with the greatest effect on lumbar spine bone mineral density relative to placebo treatment. Among the drug options, zoledronate, risedronate, and teriparatide (20 or 40mcg) demonstrated significant reductions in fracture incidence compared to placebo.
كيف سيؤثر ذلك على رعاية مرضاي؟
The results of this study offer a preliminary analysis on the current evidence regarding effect of current drug options for osteoporosis on bone mineral density increase and fracture risk reduction. In general, zoledronate may be the most effective therapy drug for increasing lumbar BMD, whereas teriparatide may be associated with the greatest reduction in fracture rate. Nevertheless, results should be interpreted with careful consideration, as head-to-head comparisons between each drug are needed to ultimately conclude which treatment option offers the greatest efficacy for men with osteoporosis. Additional, future trials should consider safety analyses associated with the treatment options evaluated in the current study.
