Inflammatory Arthritis Induced by Pembrolizumab in a Patient With Head and Neck Squamous Cell Carcinoma

Abstract: Introduction: T cell checkpoint inhibitors targeting Programmed cell Death protein-1 (PD-1) have emerged as novel immunotherapy agents showing remarkable efficacy in head and neck squamous cell carcinoma (HNSCC). Despite important clinical benefits, they are associated with side effects that occur as a consequence of general immunological stimulation due to loss of T cell inhibition. Herein, we report the unusual case of inflammatory arthritis induced by anti-PD-1 agent pembrolizumab.Case report: A 55-years ol… Show more

“…In a recent systematic review and metaanalysis of studies performed on cancer patients receiving anti-PD-1 and anti-PDL1 agents, only few individual cases of arthritis were reported at a rate below 1%. However, across the groups, musculoskeletal complaints were very common, ranging from 9 to 18% for arthralgia, 2 to 16% for back pain, 4 to 6% for musculoskeletal pain, and 4 to 16% for myalgia, suggesting that organ specific immune adverse events are uncommon with anti-PD-1 drugs, yet they are associated with a higher risk compared to control treatments (8,9). The pathophysiology of pembrolizumabinduced inflammatory arthritis has not yet been clarified.…”

“…The patient’s quality of life was severely affected due to her extensive psoriatic lesions, even though she had no evidence of metastatic disease or recurrence of NSCLC. The etiology of psoriasis and other autoimmune adverse events secondary to immunotherapy is said to be due to T-cell activation-enhanced autoimmunity [3].…”

“…Also, acute and delayed onset inflammatory polyarthritis after treatment with pembrolizumab have been reported. 18,19 However, there is no anti-VEGF therapy-induced RS3PE or arthritis cases have been reported yet. At present, main treatment of RS3PE is corticosteroids.…”
