title: [Treatment of Paget's disease of bone with zoledronic acid].
abstract: Bone pain and bone deformities are the most common manifestations of Paget's disease of bone, even if the diagnosis is nowadays most often made by chance following a routine measurement of serum alkaline phosphatase. Woven bone is formed following a marked increase in bone resorption due to a stimulation of osteoclast activity. Biphosphonates constitute the modern treatment of Paget's disease of bone. Tiludronate (Skelid), or better risedronate (Actonel), are administered orally every day during at least 2 months. Zoledronic acid (Aclasta), as a single 15-min 5 mg infusion, has been recently compared to risedronate, 30 mg/d orally for 2 months, in two randomized studies including 357 patients. Zoledronic acid had a superior therapeutic efficacy, as judged by its rapidity of action, the duration of the biochemical response and the percentage of responders. Thus, at 6 months, alkaline phosphatase levels were normalized in 89% of the patients in the zoledronic acid group as compared to 58% in the risedronate group. The most frequent side effect was a flu-like syndrome, observed in 10% of the patients. An adequate intake of calcium and vitamin D is recommended to avoid posttreatment hypocalcemia. The introduction of Aclasta should simplify and improve the therapeutic management of Paget's disease of bone.
