BACKGROUND With the widespread application of immune checkpoint inhibitor(ICI)therapy,the number of immune-related adverse effects(irAEs)has increased over the years.Autoimmune diabetes mellitus(DM)is a rare irAEs of ICIs and can be troublesome and life threatening.CASE SUMMARY We report a 78-year-old woman with no history of diabetes who presented with hyperglycemia up to 23.4 mmol/L(random blood glucose level)after 14 courses of sintilimab.Hemoglobin A1c was 8.2%,fasting insulin was 0.29 mIU/mL,and fasting C-peptide was decreased to a level with negative autoantibodies.Combing her medical history and laboratory examination,she was diagnosed with programmed cell death(PD)-1-inhibitor-induced,new-onset autoimmune DM.After controlling her blood glucose,she was treated with daily insulin by subcutaneous injection.She was allowed to continue anti-PD-1 therapy and she still obtained some therapeutic efficacy.We also reviewed some published cases(n=36)of PD-1/PD-ligand 1(PD-L1)inhibitor-induced DM.We also discuss potential pathogenic mechanisms,clinical features,prognostic markers(βcell antibodies,human leukocyte antigen type,PD-L1 Level)of this rare adverse effect.CONCLUSION It is important for all clinicians to be aware of DM as an irAEs of ICIs.
