SARLI, Marcelo et al. Clinical features, diagnostic evaluation and responses to treatment in Paget’s disease of bone in a center specialized in bone metabolism. Medicina (B. Aires) [online]. 2022, vol.82, n.3, pp.408-414. ISSN 0025-7680.

The epidemiology of Paget’s disease of bone (PDB) has changed in the last years but there is no update data on its clinical presentation, diagnosis and management in Latin America. Our aim was to describe its clinical features, diagnostic evaluation and responses to treatment in a group of PDB patients treated between June 2012 and December 2019 in an institution specialized in bone diseases, in Buenos Aires, Argentina. The frequency of PDB (180/10 714) was 1.68%. Median age was 67 (range 39-97) years and 59.5% were women. Most patients were asymptomatic (58.6%) and had monostotic disease (54.3%). Favorable responses were obtained in all patients who were treated with zoledronate (n = 36), in 10 out of 14 treated with pamidronate, in 9 out of 10 who received intravenous ibandronate and in 12 out of 13 who received oral bisphosphonates. The response rates were not significantly different when we compared monostotic vs. polyostotic disease. Among the biochemical parameters, mean values of bone specific and total alkaline phosphatase, and C-terminal cross-linked telopeptide of type I collagen decreased significantly after treatment with bisphosphonates. It seems that our results reflect the change in PDB epidemiology towards a more indolent disease. In the future, this would probably allow physicians to use lower doses of bisphosphonates than the ones historically recommended for these patients.
