Flow cytometry analysis of circulating T cells obtained at diagnosis (pre-IVIG, acute), post-CSA (36-48 hours after initiation of CSA), subacute (2-3 weeks), and convalescent (1-3 months) time points. Cell populations were defined as CD4+ T effector memory (Tem) cells (IL-15r+ CCR7−), CD8+ Tem cells (IL-15r+ CCR7−), and CD4+ CD25high Treg cells. Illness day 1 refers to the first day of fever. Tem, T effector memory cells; WBC, white blood cell.
