ABSTRACT

Objective To observe the interference of glucose-6-phosphate dehydrogenase (G6PD) deficiency on glycated hemoglobin (HbA1c) detected by three measurement systems.Methods A total of 286 cases of blood and serum samples were collected at Zhongshan Hospital of Sun Yat-Sun University from August 2012 to April 2016.The blood samples were divided into healthy control group (122 cases),diabetes group (82 cases),glucose-6-phosphate dehydrogenase deficiency group (61 cases) and diabetes with G6PD deficiency group (21 cases).The levels of HbA1 c were detected by three measurement systems,including Primus Ultra2,Variant lⅡ Turbo 2.0 and Modular P.The results of HbA1c were converted into the estimated average blood glucose concentration (eAG).The values of A eAG-FPG in different groups were calculated and statistical analysis was performed for evaluation of the differences from the three measurement systems.Results The HbA1c results measured by the three systems and AeAG-FPG values in G6PD deficiency group were all lower than healthy control group(all P <0.05).The measured results were similar in both diabetes group and diabetes with G6PD deficiency group.Conclusion G6PD deficiency may cause false H-bA1c results detected by three measurement systems.In the case of HbA1c for evaluating blood glucose control,the interference of G6PD deficiency should be noticed.

ABSTRACT

Objective To investigate the diagnostic value of dual-energy CT pulmonary angiography (DE-CTPA) and dual-energy CT lung perfusion (DE-CTLP) in the assessment of pulmonary embolism comparing with pulmonary ventilation-perfusion scintigraphy. Methods Fifty patients suspected of PE (26 males, 24 females) underwent both DE-CTPA, DE-CTLP and pulmonary ventilation-perfusion scintigraphy. The results were compared and the correlation between the intravascular clots in DE-CTPA and the perfusion defects in DE-CTLP was analyzed. The sensitivity, specificity and accuracy of DE-CTLP for PE were assessed according to scintigraphic results which was considered as a "gold" standard. Result ( 1 ) Of 50 cases,920 segments in 46 cases were diagnostable, 4 cases were not included because of the poor image quality. lntravascular clots were found in 262 segments on DE-CTPA and perfusion defects in 266 segments were identified on DE-CTLP, while 268 segments were positive on scintigraphy. (2) The perfusion defects on DE-CTLP were correlated well with the clots on CTPA ( r = 0. 883, P < 0. 01 ). The Dual energy CT Lung perfusion imaging had a good consistence with scintigraphy (Kappa = 0. 940, P <0. 01 ). The sensitivity, specificity, positive and negative predictive value were 96. 2% (279/290), 98.0%(641/654), 95. 5% (279/292) and 98. 3% (641/652), respectively. (3)The radiation dose of DE-CTPA and CE-CTLP scan was(4. 37 ± 0. 47) mSv by using CareDose 4D technique. Conclusion DE-CTPA and CE-CTLP can provide pulmonary vascular morphology and parenchyma perfusion information which are useful and valuable for the diagnosis of PE.
