A 8 month-old infant presented with acute onset of severe jaundice, anemia requiring transfusion and Glucose-6-Phosphate Dehydrogenase deficiency. The infant did not take drugs, he did not consume fava beans, but fava beans DNA was found on pumpkin he consumed the day before jaundice onset. This is the first case of hemolysis triggered by ingestion of food cross-contaminated with fava beans.

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common erythrocyte enzyme deficiency in the world. The epidemiological, biochemical and molecular studies on G6PD enzyme deficiency performed over the past 50 years are summarized herein, with special emphasis on the findings of studies related to the enzyme deficiency in Turkey.

Background: Jaundice is affecting over 60-80 percent of neonates in the first week of life. Glucose-6-phosphate dehydrogenase (G6PD) deficiency, which is an important cause of pathologic hyperbilirubinemia, can lead to hemolytic anemia, jaundice and kernicterus. The present study was performed to determine the prevalence of G6PD deficiency among icteric neonates in Shirvan, Iran. Methods: This...

Glucose-6-phosphate dehydrogenase (G6PD) activity and the affinity for its substrate glucose-6-phosphate were investigated under conditions similar to the physiological environment in terms of ionic strength (I: 0.188), cation concentration, pH 7.34, and temperature (37 degrees C). A 12.4, 10.4 and 21.4% decrease was observed in G6PD B, G6PD A+ and G6PD A- activities, respectively. A Km increas...

n-Glucose-6-phosphate dehydrogenase (Zwischenferment) was discovered by Warburg and Christian in 1931 (1, 2). An active preparation was obtained then from horse erythrocytes and in 1932 from the Lebedev juice made from brewers’ yeast (3). Because of its extreme specificity, this enzyme has become an important analytical tool. Various preparations of it have been described, the first being those...

A new D-glucose-6-phosphate phosphohydrolase (G6Pase) inhibitor, CJ-21,164 (1) was isolated from the fermentation broth of the fungus Chloridium sp. CL48903. The structure was elucidated to be a novel tetramer of the salicylic acid derivatives by spectroscopic analyses. Compound I inhibited G6Pase in rat liver microsomes with an IC50 of 1.6 microM. Glucose output from hepatocytes isolated from ...

Renewed interest in the direct oxidative pathway of glucose 6-phosphate metabolism during the last few years has revealed that this pathway is by no means restricted to erythrocytes, yeast and microorganisms. The triphosphopyridine-nucleotide(TPN)-specific glucose 6-phosphate and 6-phosphogluconate dehydrogenases are also widely distributed in mammalian tissues (Dickens & Glock, 1950, 1951; Hor...
