Cytokine release syndrome-like serum responses after COVID-19 vaccination are frequent and clinically inapparent under cancer immunotherapy

Abstract: Patients with cancer frequently receive immune-checkpoint inhibitors (ICIs), which may modulate immune responses to COVID-19 vaccines. Recently, cytokine release syndrome (CRS) was observed in a patient with cancer who received BTN162b2 vaccination under ICI treatment. Here, we analyzed adverse events and serum cytokines in patients with 23 different tumors undergoing (n = 64) or not undergoing (n = 26) COVID-19 vaccination under ICI therapy in a prospectively planned German single-center cohort study (n = 220… Show more

“…Additionally, we investigated whether CCG responses are different in patients who developed severe AE: only placental growth factor (PlGF) was observed to be significantly downregulated after the primer dose in an uncorrected paired t-test statistics ( p = 0.027) and was not significant after post-hoc false discovery rate correction. These data fit well with studies suggesting that systemic adverse events noted after vaccination in cancer patients are not necessarily vaccine related [5, 28].…”

“…To the best of our knowledge, a higher prevalence of AEs in patients with long-standing disease or long duration of immunotherapy has not been reported, but this may reflect a more robust reaction of the immune system and cytokine production in patients with effectively activated T-cells. Cytokine-release syndrome-like serum responses have been recently reported in cancer patients under immunotherapy who have been vaccinated against SARS-CoV-2 [ 24 , 25 ].…”

“…Immunotherapies can enhance the immune response by reinvigorating exhausted T cells, and therefore may potentiate cell-mediated vaccine responses. Despite the amplified immune response with ICIs, patients rarely display symptoms of immunerelated adverse events (irAEs) or cytokine release syndrome (CRS), thus highlighting a favourable safety profile in this cohort [103]. Patients on endocrine or targeted therapies are unlikely to have treatment-driven reduced vaccine-induced immune responses [15][16][17]23].…”
