Article Synopsis
  • * This study analyzes six new cases of HK deficiency, identifying six distinct mutations in the HK1 gene, four of which are newly discovered.
  • * The research also confirmed the harmful nature of these mutations through biochemical tests and structural analysis, further enhancing understanding of the disease's underlying mechanisms and the relationship between genotype and phenotype in HK deficiency.

Background: Acute lymphoblastic leukemia (ALL) is the most frequent childhood malignancy. Treatment has been unified in the middle of 1980 in the Czech Republic. In 2002-2007 children and adolescents with acute lymphoblastic leukemia were treated in an international randomized trial ALL-IC BFM 2002 in the Czech Republic.

Introduction: Glucocorticoids, particularly prednisone/ prednisolone and dexamethasone, play a prominent role in the treatment of pediatric patients with acute lymphoblastic leukemia due to their ability to induce apoptosis in susceptible cells. Current therapeutic protocols use prednisone for both the prophase and the induction phase of the therapy because the greater antileukemic activity of dexamethasone is compromised by its high frequency of serious adverse reactions.

Aim: To compare, for the first time, the in vitro antileukemic activity of prednisolone alone to that of a combination of prednisolone and dexamethasone using dexamethasone at a very low and presumably safe dosage (1/50 w/w).

Diamond-Blackfan anemia is a rare inherited bone marrow failure syndrome diagnosed in early infancy that is characterized by a (a) macrocytic anemia with no other significant cytopenia, (b) reticulocytopenia, and (c) normal bone marrow cellularity with a paucity of erythroid precursors. Physical anomalies are often present. Mutations in several ribosomal proteins have been associated with the disease.
