Zoledronic acid reduces the risk of death by 28% after hip fracture, but the mechanisms are not known. This exploratory analysis sought to identify potential pathways for the reduction in mortality with zoledronic acid after hip fracture. This was a retrospective analysis of a randomized, controlled trial. Patients with recent hip fracture (n = 2111) were treated with zoledronic acid or placebo infusion yearly, as well as calcium and vitamin D supplementation. Causes of death were adjudicated by a blinded central review committee. Baseline comorbidities, events occurring during the study period, including subsequent fracture, change in bone density, infections, cardiovascular events, arrhythmias, and falls, were included in multivariable analyses. In a model adjusted for baseline risk factors, zoledronic acid reduced the risk of death by 25% [95% confidence interval (CI) 0.58-0.97). The effect was consistent across most subgroups. Subsequent fractures were significantly associated with death (hazard ratio 1.72, 95% CI 1.17-2.51) but explained only 8% of the zoledronic acid effect. Adjusting for acute events occurring during follow-up eliminated the death benefit, and zoledronic acid-treated subjects were less likely to die from pneumonia (interaction p = .04) and arrhythmias (interaction p = .02) than placebo-treated subjects. Only 8% of zoledronic acid's death benefit is due to a reduction in secondary fractures. Zoledronic acid may have an effect on cardiovascular events and pneumonia. Further studies of zoledronic acid in other acute illnesses may be warranted.

The European Myeloma Network provides recommendations for the management of the most common complications of multiple myeloma. Whole body low-dose computed tomography is more sensitive than conventional radiography in depicting osteolytic disease and thus we recommend it as the novel standard for the detection of lytic lesions in myeloma (grade 1A). Myeloma patients with adequate renal function and bone disease at diagnosis should be treated with zoledronic acid or pamidronate (grade 1A). Symptomatic patients without lytic lesions on conventional radiography can be treated with zoledronic acid (grade 1B), but its advantage is not clear for patients with no bone involvement on computed tomography or magnetic resonance imaging. In asymptomatic myeloma, bisphosphonates are not recommended (grade 1A). Zoledronic acid should be given continuously, but it is not clear if patients who achieve at least a very good partial response benefit from its continuous use (grade 1B). Treatment with erythropoietic-stimulating agents may be initiated in patients with persistent symptomatic anemia (hemoglobin <10g/dL) in whom other causes of anemia have been excluded (grade 1B). Erythropoietic agents should be stopped after 6-8 weeks if no adequate hemoglobin response is achieved. For renal impairment, bortezomib-based regimens are the current standard of care (grade 1A). For the management of treatment-induced peripheral neuropathy, drug modification is needed (grade 1C). Vaccination against influenza is recommended; vaccination against streptococcus pneumonia and hemophilus influenza is appropriate, but efficacy is not guaranteed due to suboptimal immune response (grade 1C). Prophylactic aciclovir (or valacyclovir) is recommended for patients receiving proteasome inhibitors, autologous or allogeneic transplantation (grade 1A).
