Rheumatology Flashcards
Markers of bone turnover in Paget’s
Raised alkaline phosphatase (ALP)
Serum C-telopeptide (CTx)
Urinary hydroxyproline
Management of Paget’s
Bisphosphonate
(either oral risedronate or IV zoledronate)
Denosumab
RANKL inhibitor (Human monoclonal antibody)
Prevents the development of osteoclasts
Bony metastases - bone protection
Bisphosphonates and denosumab can be used to prevent pathological fractures in bone metastases.
If the eGFR < 30, denosumab is preferred
