简介:AbstractBackground:The elimination of Plasmodium vivax malaria requires 8-aminoquinolines, which are contraindicated in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency due to the risk of acute haemolytic anaemia. Several point-of-care devices have been developed to detect G6PD deficiency. The objective of the present study was to evaluate the performance of two of these devices against G6PD genotypes in Mauritania.Methods:Outpatients were screened for G6PD deficiency using CareStart™ rapid diagnostic test (RDT) and CareStart™ G6PD biosensor in Nouakchott, Mauritania, in 2019-2020. African-type and Mediterranean-type G6PD genotypes commonly observed in Africa were determined by polymerase chain reaction-restriction fragment length polymorphism and sequencing. Qualitative variables were compared using Fisher’s exact test.Results:Of 323 patients (74 males and 249 females), 5 males and 2 homozygous females had the African-type A-genotype: A-(202) in 3 males and 2 females and G6PD A-(968) in 2 males. Among heterozygous females, 13 carried G6PD A-(202), 12 G6PD A-(968), and 3 G6PD A-(542) variants. None had the Mediterranean-type G6PD genotype. Eight had a positive G6PD RDT result, including all 7 hemizygous males and homozygous females with A- or A-A- (0.12 to 2.34 IU/g haemoglobin, according to G6PD biosensor), but RDT performed poorly (sensitivity, 11.1% at the cutoff level of < 30%) and yielded many false negative tests. Thirty-seven (50.0%) males and 141 (56.6%) females were anaemic. The adjusted median values of G6PD activity were 5.72 and 5.34 IU/g haemoglobin in non-anaemic males (n = 35) and non-anaemic males and females (n = 130) with normal G6PD genotypes using G6PD biosensor, respectively. Based on the adjusted median of 5.34 IU/g haemoglobin, the performance of G6PD biosensor against genotyping was as follows: at 30% cut-off, the sensitivity and specificity were 85.7% and 91.7%, respectively, and at 80% cut-off, the sensitivity was 100% while the specificity was 64.9%.Conclusions:Although this pilot study supports the utility of biosensor to screen for G6PD deficiency in patients, further investigation in parallel with spectrophotometry is required to promote and validate a more extensive use of this point-of-care device in areas where P. vivax is highly prevalent in Mauritania.
简介:摘要目的探讨中药抗癌1号和抗癌2号对肝癌细胞凋亡的影响。方法用1640培养基培养肝癌细胞(Hepg2)分别加入不同的抗癌中药一起培养,并设一组标准抗癌药和一组不加中药的培养。培养5d后,在倒置显微镜下观察细胞生长情况并拍摄图片分析,收集细胞计数。结果抗癌1号、抗癌2号、三尖杉和对照组细胞计数分别为1644.0±404.1、2345.0±169.5、2373.5±542.7、3410.3±377.3万个/ml,对照组明显高于其他组(P<0.05,P<0.01);加药三个组细胞均表现粗糙、颗粒多、易剥落凋亡现象。结论抗癌1、2号和对照药物对肝癌细胞生长均有明显的抑制作用,促进癌细胞凋亡。
