Abstract
Charcot neuroarthropathy is a devastating condition, most commonly affecting poorly controlled diabetic patients with peripheral neuropathy. Pharmacological options for the condition are currently limited. The purpose of this study was to investigate the potential of Prolia® (denosumab) as a safe and feasible option in the treatment of acute Charcot neuroarthropathy. A total of 7 consecutive subjects were enrolled and followed for 1 year. Subjects received a single one-time injection of denosumab 60 mg. Subjects also received standard of care treatment, which included total contact casting, restricted weightbearing status, and biweekly office visits until normalization of the skin temperature gradient. Overall, the pharmaceutical treatment was generally well-tolerated. One subject developed a diabetic foot infection with cellulitis of the contralateral lower extremity, which occurred following the 6-month follow-up visit and which resolved with oral antibiotics One subject identified transient muscle pain in the same upper extremity which received the injection. Subjects were found to exit the acute phase of the condition at an average of 52.00 ± 17.89 days after their injection, which was defined by normalization of skin temperature to within 2°C of the contralateral foot. Treatment of acute Charcot neuroarthropathy with denosumab was well-tolerated in this open-label, pilot study. The clinical outcomes suggest that the medication may be efficacious, though a larger sample size would be needed to confirm these preliminary results. An adequately-powered, randomized, controlled study may be an appropriate follow-up.
