“…Although white blood cell counts were frequently increased (12,800/μl [9150–20,075]), lymphocytopenia was common (831.5/μl [510–1157.5]) [ 12 , 24 , 30 – 36 , 39 – 41 , 43 – 46 , 48 – 50 , 52 – 57 , 60 , 62 , 67 – 73 , 75 , 77 , 80 , 84 ], contrasting with historical KD cohorts [ 15 , 64 ] (median lymphocytes 2800–3080/μl) or non-PIMS-TS/MIS(-C) (median 2100/μl) [ 23 ]. Most PIMS-TS/MIS(-C) presented reduced to normal thrombocytes (platelets below 150,000/μl in 44/104; 42.3%) [ 11 , 12 , 24 , 30 , 32 – 36 , 38 , 40 , 41 , 43 – 46 , 48 , 50 , 52 – 56 , 62 , 66 – 68 , 70 , 71 , 77 , 80 , 84 ]. Thrombocytosis (platelets above 450,000/μl), a typical KD sign and a laboratory criterium for incomplete KD [ 87 ], occurred in only 5/104 (4.8%).…”
