A case report involving suppressed nuclear receptor transcription factors 4a1 and Stevens-Johnson syndrome induced by a single dose of pembrolizumab and successfully treated with early steroid administration, resulting in complete remission of stage III lung cancer.

ABSTRACT:

Background

Immunotherapy with immune checkpoint inhibitors is associated with immune-related adverse events (irAEs). A positive correlation between treatment efficacy and irAEs has been reported. Clinical indicators are required for appropriate interventions, such as steroid administration, to prevent fatal outcomes. Nuclear receptor transcription factor 4a (Nr4a), which is involved in T-cell anergy, exhaustion, and regulatory T cells, were observed not only in thymocytes but in peripheral blood mononuclear cells. We describe a case of Stevens-Johnson syndrome (SJS) that was induced by a single dose of pembrolizumab and successfully treated with steroids, leading to complete remission of lung cancer during the monitoring of immune response indices, including Nr4a1 mRNA.
