Abstract
Glucose-6-phosphate dehydrogenase (G6PD) represents a common human enzyme defect, particularly prevalent in the Mediterranean, African e Asian area, where malaria was or is still endemic. Recently, we identified G6PD deficiency as a risk factor for developing invasive fungal disease (IFD) and particularly Candida Sepsis in patients undergoing intensive chemotherapy for acute myeloid leukemia (AML), suggesting that there is an urgent need for strategies to properly manage this kind of patients at high risk of invasive mycoses. Here we propose our algorithm for correct identification, prophylaxis, and treatment of IFD in patients with G6PD deficiency undergoing intensive chemotherapy for AML.

Abstract
Invasive fungal diseases (IFD) are still a leading cause of morbidity and mortality in patients with acute myeloid leukemia (AML). Glucose-6-phosphate dehydrogenase is an enzyme that leads to the production of NADPH, required to destroy microorganisms in the respiratory burst reaction of white blood cells. We evaluated the role of G6PD deficiency in susceptibility of IFD in 108 AML patients undergoing intensive chemotherapy. In all, 28 patients harbored G6PD deficiency (G6PD-), whereas 80 were normal (G6PD +). Incidence of IFD was significantly higher in G6PD- patients compared to G6PD + patients (35.7% vs. 5%, p = .0002, OR = 10, 95% CI = 2.96-37.5). Higher risk of mold infections (17.9% vs. 5%, p = .048, OR = 4.1, 95% CI = 1.0-16.6) and Candida sepsis (17.9% vs. 0%, p = .0009, OR = 37.68, 95% CI =2.0-707.1) was observed in G6PD - patients. The evaluation of G6PD activity may help to identify AML patients at higher risk of IFD, allowing to design more intensive surveillance and therapeutic strategies.

Abstract
We have carried out a systematic study of the molecular basis of glucose-6-phosphate dehydrogenase (G6PD) deficiency on three samples of 1,183 children aged 0.5-6 years from Erzurum, in eastern Anatolia. Total genomic DNAs were isolated from the blood samples of a healthy person and the three persons determined with G6PD deficiency by examining the enzyme activity and hemoglobin ratio. Then PCR amplification of the entire coding region in eight fragments was carried out followed by Agarose gel electrophoresis. The 540-bp PCR fragment containing exons VI-VII and the 550bp PCR fragment containing exons XI-XIII were digested with EcoRI and with NIaIII, respectively. SSCP techniques for eight fragments (exons II, III-IV, V, VI-VII, VIII, IX, X, and XI-XIII) were employed to determine the mutations on the exons of the G6PD gene. A mutation occurred on the region of the exons 6 and 7 of one person (person-1) and exon 5 of two G6PD-deficient persons (person 2 and 3) examined. The sequential approach described is fast and efficient and could be applied to other populations. Effects of analgesic drugs on G6PD were studied on the purified enzyme (ammonium fractionation, dialysis and 2',5' ADP-Sepharose 4B affinity chromatography) for the healthy person and G6PD-deficient persons 1, 2 and 3. The effects of remifentanil hydrochloride, fentanyl citrate, alfentanil hydrochloride and pethidine hydrochloride, as analgesic drugs, on G6PD activity were tested. Although remifentanil hydrochloride, fentanyl citrate (I50 values; 1.45mM and 6.1 mM, respectively) inhibited the activity of the enzyme belonging to the healthy person, they did not alter enzyme activity on two of the three persons with G6PD deficiency. Other drugs (alfentanil hydrochloride and pethidine hydrochloride) did not effect the enzyme activity of the healthy or G6PD-deficient children.

Abstract
BACKGROUND AND OBJECTIVES Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a genetic enzymatic disorder that affects millions of people worldwide, and is a major health problem in Jordan. We studied factors that may predict severe hemolysis in children with G6PD deficiency. METHODS We reviewed the records of patients with low G6PD activity admitted to a teaching hospital be- tween 1996 to 2007. We collected demographic data, details of sign and symptoms, history and type of fava bean ingestion, blood and Rh group, history of neonatal jaundice, history and type of drug use, abdominal pain at admission and the results of tests for hemoglobin, white blood cells (WBC), and hepatic function. We classified patients into mild and severe groups based on hemoglobin levels at admission. RESULTS Of 428 children with G6PD deficiency, 79 (18%) were severe cases and 349 (82%) patients with mild disease. There were no statistically significant differences in most factors between the two groups. Factors that achieved statistical significance for severe hemolysis included younger age (P<.05), male gender (P<.05), higher alkaline phosphatase (ALP) (P<.05), presence of fever at admission (P<.01), presence of vomiting during the at- tack (P=.006), and a negative family history for G6PD deficiency (P=.005). CONCLUSIONS Severe hemolysis can be predicted during hemolytic episodes in children with low G6PD by young age, male gender, a negative family history of G6PD deficiency, the presence of fever and vomiting and a high ALP.

Abstract
The purpose of this study was to investigate effects of some antibiotics on glucose-6-phosphate dehydrogenase (G6PD), antioxidant enzymes, and malondialdehyde (MDA). Initially, for in vitro studies, G6PD was purified from human erythrocyte, 9811-fold in a yield of 42.4% by using ammonium sulfate precipitation and 2',5' ADP-Sepharose 4B affinity gel. The purified enzyme showed a single band on sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). The effects of four different antibiotics (isepamicin sulfate, meropenem, chloramphenicol, and thiamphenicol glisinat hydrochloride) were investigated on the purified enzyme. K(i) value and type of inhibition were determined by means of Lineweaver-Burk graphs and regression analysis graphs. Isepamicin sulfate inhibited the enzyme activity (I(50) value, 2.1 mM; K(i) value, 1.7 mM), whereas thiamphenicol glisinat hydrochloride activated the G6PD dose dependently. Other drugs showed no inhibition and activation effect. In addition, the effects of isepamicin sulfate on the activities of G6PD, glutathione reductase (GR), superoxide dismutases (SOD), glutathione peroxidase (GPx), catalase (CAT), and glutathione S-transferase (GST) and MDA concentrations were examined in Sprague-Dawley rat erythrocytes in vivo. A marked alteration in the activities of these enzymes and MDA levels may be the result of oxidative stress in the rats receiving isepamicin sulfate.

Abstract
Corticosteroids are anti-inflammatory drugs that are similar to the natural corticosteroid hormones produced by the cortex of the adrenal glands. The objective of this study was to scrutinize effects of some corticosteroids on glucose-6-phosphate dehydrogenase (G6PD) and some antioxidant enzymes. Initially, G6PD was purified from human erythrocytes by using ammonium sulphate precipitation and affinity chromatography. The two drugs, dexamethasone phosphate and prednisolone, investigated on the purified enzyme inhibited the enzyme activity. Comparative in vivo studies were performed to determine the effects of dexamethasone phosphate on the antioxidant enzyme activities using Spraque-Dawley rats. G6PD and catalase (CAT) activities were found significantly lower than in the control, whereas glutathione peroxidase (GP) activity was significantly increased in the erythrocytes of rats the receiving drug; glutathione reductase (GR) activity was unaffected. The results imply that dexamethasone phosphate may affect oxidative stress by changing antioxidant enzyme activities.

Abstract
The incidence of infections among patients with thalassaemia and the role of risk factors for infection are uncertain. We studied the occurrence of infections necessitating hospitalisation in 92 homozygous beta-thalassaemia patients who had been followed longitudinally for decades, and investigated the role of potential risk factors for these infections. Pneumonia accounted for 26% of the infections and fever of unknown origin for 14%. Staphylococcus aureus was the major pathogen possibly related to injections associated with intensive chelation with deferoxamine. There was a significant increase in the rate of infection over time, notably after 15 years. Splenectomy correlated with the incidence of infection (P < 0.001) without being confounded by other variables and with highest frequencies of infections present after 10 years. A direct correlation between iron overload and infection was evident only before the initiation of iron-chelating treatment (P < 0.01). Following initiation of deferoxamine, paradoxically, the infection rate increased (P = 0.046). The combination of splenectomy and deferoxamine treatment was associated with the highest adjusted infection rate. Parathyroid dysfunction and glucose-6-phosphate dehydrogenase deficiency were significantly associated with infection (P = 0.02 and P = 0.04 respectively). The infection rate in thalassaemia is affected mainly by the duration of the disease and is increased by splenectomy and, in the long term, by treatment with deferoxamine.

Abstract
The aim of this study was to investigate effect of antiemetics on G6PD and antioxidant enzymes. Antiemetics are currently being used to reduce or prevent nausea and vomiting in patients. This is the first study to show effect of antiemetics on glucose-6-phosphate dehydrogenase (G6PD) and antioxidant enzyme activities. For in vitro studies, G6PD was purified from human erythrocyte, 10, 26-fold in a yield of 51.3% by using ammonium sulphate precipitation and 2',5'-ADP-Sepharose 4B affinity gel. The purified enzyme showed a single band on sodium dodecyl sulfate-polyacrilamide gel electrophoresis (SDS-PAGE). The effects of four different antiemetics (granisetron hydrochloride, ondansetron hydrochloride, metoclopramide hydrochloride, trimethobenzamide hydrochloride) were investigated on the purified enzyme. Granisetron hydrochloride and ondansetron hydrochloride inhibited the enzyme activity (Ki values; 5.05 mM and 0.034 mM, I50 values; 3.9 mM and 0.036 mM, respectively). Metoclopramide hydrochloride, trimethobenzamide hydrochloride showed no inhibition effects. In addition, in vivo studies, effects of ondansetron hydrochloride on the G6PD, glutathione reductase (GR), glutathione peroxidase (GPx) and catalase (CAT) were examined in the rat erythrocytes. G6PD (49% of control), GR (55% of control), CAT (60% of control) activities in erythrocytes were significantly decreased whereas GPx (183% of control) was significantly increased. A marked alteration in these enzymes may be result of oxidative stress in the rats receiving ondansetron hydrochloride.

Abstract
BACKGROUND It has recently been suggested that primary lactase deficiency might have been selected for by malaria, as has been previously shown to occur for thalasaemia and glucose 6-phosphate dehydrogenase (G6PD) deficiency. AIMS To test this hypothesis, the prevalence of primary lactase deficiency in G6PD deficient subjects and in controls from the area of Sassari (Northern Sardinia) was determined, which in the past was characterised by an intermediate malarial endemicity. SUBJECTS 70 adult subjects with G6PD deficiency, 34 of whom had a past history of favism, and 50 age matched control subjects. METHODS The capacity to absorb lactose was assessed by measuring breath hydrogen production after oral administration of lactose (50 g) by a gas chromatographic method. RESULTS Twenty per cent of G6PD deficient subjects with a positive history of favism and 22% of G6PD deficient subjects without a positive history of favism were lactose absorbers compared with 14% lactose absorbers in the control group. The differences were not statistically significant. CONCLUSIONS These data show that the prevalence of primary lactase deficiency in the area of Sassari is relatively high, but comparable to that seen in the adult population from another area of southern Italy (Naples) where malaria was less endemic.
