Case ReportsLidocaine Infusion: An Analgesic Option for Checkpoint Inhibitor Arthritis: A Case Report.
This report describes the use of subcutaneous lidocaine infusion to manage complex pain associated with checkpoint inhibitor inflammatory arthritis. In addition, the safe administration of lidocaine in the home setting is described. A 49-year-old man with metastatic melanoma to lung, right axilla and posterior chest wall on regular pembrolizumab developed checkpoint inhibitor inflammatory arthritis. ⋯ Inflammatory pain responded well to 2 mg/kg/h lidocaine infusion over 4 days with sustained response between infusions of up to 6 wk. Resulting in improved mobility, functional status, and overall quality of life. Lidocaine infusion should be considered as an option for analgesic management of checkpoint inhibitor inflammatory arthritis in patients for whom usual treatment is ineffective, and as an opioid-sparing intervention.
