Abbreviations: F = female; M = male; (v)SAA = (very) severe aplastic anemia; n = no; y = yes; PB = peripheral blood; BM = bone marrow; I = pool I at initial presentation (n = 4); IIa = pool II at initial presentation (n = 2); IIb = pool II in hematological remission (n = 2). Disease classification was performed according to the International Study of Aplastic Anemia and Agranulocytosis [45].
