Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an enzymopathy in which reduced NADPH concentrations are not maintained, resulting in oxidative damage. We evaluated G6PD activity, oxidative stress levels and Trolox equivalent antioxidant capacity in individuals with the A-(202G>A) mutation for G6PD deficiency. Five hundred and forty-four peripheral blood samples were screened for G6PD de...

is known about the safety of RBV treatment in patients with concomitant glucose-6-phosphate dehydrogenase (G6PD) deficiency, who are inherently prone to hemolysis.5 We prospectively studied changes in hemoglobin (Hb) levels in 112 patients with chronic hepatitis C, associated or not with G6PD deficiency, during and after combination therapy. G6PD activity was tested by a spectrophotometric meth...

Tumor lysis syndrome (TLS) is a life-threating hematologic emergency caused by massive lysis of tumor cells into the blood stream. TLS can be prevented and treated with rasburicase. Rasburicase-induced hemolysis and methemoglobinemia is a rare but serious complication. Screening for G6PD should be considered for patients at higher risk for G6PD deficiency who may be also at high risk for TLS on...

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is common in malaria endemic regions and is estimated to affect more than 400 million people worldwide. Deficient subjects are mostly asymptomatic but clinical manifestations range from neonatal jaundice due to acute hemolytic anemia to chronic non-spherocytic hemolytic anemia. To date, biochemical parameters allowed more than 400 different G6...

BACKGROUND Previously published data have demonstrated that sickle red blood cells produce twice as much reactive oxygen species (ROS) suggesting that co-inheritance of sickle cell disease (SCD) and glucose 6-phosphate dehydrogenase (G6PD) enzymopathy could lead to more severe anaemia during sickling crises. Elevated foetal haemoglobin (Hb F) levels have been shown to have positive modulatory e...

Background: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common enzyme disorder in human. The aim of this study was to determine the prevalence of G6PD deficiency among children and evaluate its association with ABO/Rh blood groups. Method: Blood samples of 3401 asymptomatic children were analyzed and compared with 317 children who were admitted to hospital because of hemolys...

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an X-linked hereditary disease that predisposes red blood cells to oxidative damage. G6PD deficiency is particularly prevalent in historically malaria-endemic areas. Use of primaquine for malaria treatment may result in severe hemolysis in G6PD deficient patients. In this study, we systematically evaluated the prevalence of G6PD deficiency ...

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an X-linked genetic disorder characterized by low levels of the G6PD enzyme. It is present worldwide but with more prevalence in the Middle East and the Mediterranean areas. We report a case of severe hemolysis due to G6PD deficiency manifesting as methemoglobinemia in a 70 year old Omani male never known to have any previous hemolytic epis...

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is common in tropical Sub-Saharan countries. The allele most frequently associated with G6PD deficiency in this a region is G6PD 376G/202A. Here, we show that, the prevalence of G6PD deficiency is 12% in the Sereer ethnic group from Senegal ant that the 376G/968C genotype is predominant; the frequency of the 376G/202A genotype is very low in t...

The major role of glucose-6-phosphate dehydrogenase (G6PD) is to generate reduced nicotinamide adenine dinucleotide phosphate (NADPH), which is indispensable to reductive metabolism and maintenance of cellular redox homeostasis. Most advances in this field have been made in the pathophysiology of G6PD-deficient erythrocytes and the molecular characterization of different G6PD variants. Recently...
