    Abstract:
    Early-onset familial Paget disease of bone (EoPDB) is a rare condition caused by a 27-bp insertion mutation affecting the signal peptide of TNFRSF11A, which encodes RANK. EoPDB shows phenotypic overlap to both familial expansile osteolysis and expansile skeletal hyperphosphatasia, which are caused by similar mutations in TNFRSF11A. Although EoPDB is characterized by elevated bone turnover, there is no published information on the response of this condition to antiresorptive therapy. Here, we describe the clinical and biochemical response to bisphosphonate therapy in three patients with EoPDB. In all cases, treatment with the first-generation bisphosphonate etidronate at high doses reduced biochemical markers of bone turnover but the response was incomplete and short-lived. In contrast, treatment with aminobisphosphonates resulted in greater suppression of biochemical markers of bone turnover with an extended duration of response. From a clinical perspective, the results were less impressive and there was no clear benefit from antiresorptive treatment in terms of bone deformity, deafness, and tooth loss, although bone pain improved in one patient. We conclude that intravenous aminobisphosphonate therapy may be the preferred mode of treatment for EoPDB to provide long-term suppression of bone turnover. The long-term clinical effects of treatment on the natural history of the bone disease remain uncertain however, and this will require further study.
