Normalisation of red blood cell pyruvate kinase in pyruvate kinase deficiency by riboflavin treatment

Prevalence of Pyruvate Kinase Deficiency among the Newborns (Shiraz-Iran)

Background: The frequency of pyruvate kinase (PK) deficiency, an autosomal recessive defect, is approximately 3 per 10,000 individuals in Shiraz and surrounding areas, and is increased due to high consanguinity marriage frequency. The purpose of this study is to obtain data on the frequency and spectrum of gene mutation of PK in newborns, from Shiraz and surrounding areas. Materials and Methods...

Red cell pyruvate kinase deficiency: molecular and clinical aspects.

Red cell pyruvate kinase (PK) deficiency is the most frequent enzyme abnormality of the glycolytic pathway causing hereditary non-spherocytic haemolytic anaemia. The degree of haemolysis varies widely, ranging from very mild or fully compensated forms, to life-threatening neonatal anaemia and jaundice necessitating exchange transfusions. Erythrocyte PK is synthesized under the control of the PK...

Pyruvate Kinase Deficiency (PKD) — Symptoms and Treatment

Pyruvate kinase deficiency is an inherited metabolic disorder characterized by a deficiency in the enzyme "pyruvate kinase" causing hemolytic anemia. It is more severe in early presentation, and it has no sex predilection. The majority of the cases occur because of genetic mutation while some may be caused by diseases such as leukemia and refractory sideroblastic anemia. PKD presents with sever...
