Table 2 Simple regression analysis of the pembrolizumab level, prednisolone dose, predictive factors for serious immune-related adverse events and immune response indices, such as selected immune response indices related to blood levels of Nr4a1 and Nr4a2 mRNA

From: 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

  1. The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were used as predictive factors for serious immune-related adverse events. The plasma concentrations of pembrolizumab and cytokines, such as IL-17, IFN-γ, and IL-10, were evaluated by ELISA. Target mRNAs, such as Nr4a1, Nr4a2, IL-23 receptor (IL-23R), Foxp3, RORγt, and Lag3, were evaluated by RT‒qPCR methods with extracted total RNA from peripheral blood mononuclear cells. *p < 0.05, **P < 0.001
