An evidence based clinical guideline for the diagnosis and management of Paget’s disease of Bone (PDB) was developed using GRADE methodology, by a Guideline Development Group (GDG) led by the Paget’s Association (UK). A systematic review of diagnostic tests, pharmacological and non-pharmacological treatment options was conducted which sought to address several key questions of clinical relevance. Twelve recommendations and five conditional recommendations were made but there was insufficient evidence to address eight of the questions posed. The following recommendations were identified as the most important. Radionuclide bone scans, in addition to targeted radiographs, are recommended as a means of fully and accurately defining the extent of the metabolically active disease in patients with PDB.Serum total alkaline phosphatase (ALP) is recommended as a first line biochemical screening test in combination with liver function tests in screening for the presence of metabolically active PDB.Bisphosphonates are recommended for the treatment of bone pain associated with Paget’s disease. Zoledronic acid is recommended as the bisphosphonate most likely to give a favourable pain response.Treatment aimed at improving symptoms is recommended over a treat-to-target strategy aimed at normalising total ALP in PDB.Total hip or knee replacements are recommended for patients with PDB who develop osteoarthritis in whom medical treatment is inadequate. There is insufficient information to recommend one type of surgical approach over another.
The guideline was endorsed by the European Calcified Tissues Society, the International Osteoporosis Foundation, the American Society of Bone and Mineral Research, the Bone research Society (UK) and the British Geriatric Society. The GDG noted that there had been a lack of research on patient-focused clinical outcomes in PDB and identified several areas where further research was needed.
