Gemtuzumab Ozogamicin Monotherapy Is a Well-tolerated Palliative Chemotherapy Option in Pediatric Multiply Relapsed Acute Myeloid Leukemia: A Multicenter Case Series and Review of the Literature.

Gemtuzumab ozogamicin (GO) is an anti-CD33 antibody that is Food and Drug Administration approved in upfront acute myeloid leukemia (AML) for patients over 1-month old, and for relapsed or refractory AML in patients over 2 years old. GO is now integrated in upfront pediatric AML treatment, and often in CD33+ relapse treatment combined with intensive conventional chemotherapy. Although GO was initially tested as a monotherapeutic agent in relapsed or refractory AML, there are few data in pediatric patients supporting this indication.

Congenital dyserythropoietic anemia type IV in the genetic era: A rare neonatal case report of rapid identification with a review of the literature.

Congenital dyserythropoietic anemia type IV (CDAIV) is a rare inherited hematological disorder, presenting with severe anemia due to altered erythropoiesis and hemolysis, with variable needs for recurrent transfusions. We present a case of a transfusion-dependent male newborn who presented at birth with severe hemolytic anemia, and required an intrauterine transfusion. Genetic testing rapidly identified a Kruppel-like factor 1 (KLF1) pathogenic variant (c.
