A case of Paget's disease in hemodialysis

Paget's disease is the second most common bone disease after osteoporosis and causes an excessive bone turnover. Moreover, chronic kidney failure causes an impairment of bone mineral metabolism and electrolytes and PTH homeostasis. As far as we know, this is the first reported case of Paget's disease in a hemodialysis patient: the patient was also affected by secondary hyperparathyroidism and was successfully treated with clodronate, cinacalcet and paracalcitol. The safety and efficacy of this combined therapy was periodically revised in a 12-month follow-up considering the common markers of bone turnover as well as the dosage of OPG, RANKL, IL-6 and MCSF, involved in the pathophysiology of Paget's disease.
