Data are reported from a recent cohort (32) and review (36). N, number; IQR, interquartile range; T1DM, type 1 diabetes mellitus; AIHA, autoimmune hemolytic anemia; WBC, white blood cells; NK, natural killer.
Data about severe infections refers to patients who did not yet start immunosuppressive drugs or did not yet undergo hematopoietic stem cell transplantation.
Higher compared to healthy ranges for infants.
