摘要:

ELISA检测贵州省白血病和淋巴瘤患者各150例血样中弓形虫特异性抗体(IgG、IgM)和循环抗原(CAg),计算阳性率。PCR扩增弓形虫529 bp特异性片段。结果显示,白血病患者弓形虫IgG和IgM抗体阳性率分别为16.0%(24/150)和2.7%(4/150),CAg阳性率为2.0%(3/150)。淋巴瘤患者弓形虫IgG和IgM抗体阳性率分别为20.0%(30/150)和1.3%(2/150),CAg阳性率为0.7%(1/150)。健康人IgG和IgM抗体阳性率分别为6.4%(7/110)和0.9%(1/110),CAg阳性率为0.9%(1/110)。白血病患者、淋巴瘤患者和健康人之间弓形虫IgG抗体阳性率差异有统计学意义(P<0.05),白血病和淋巴瘤患者间IgG抗体阳性率差异无统计学意义(P>0.05);弓形虫IgM抗体和CAg阳性率在各组间差异均无统计学意义(P>0.05)。白血病患者、淋巴瘤患者和健康人血样中均未扩增出529 bp特异性条带。

Abstract:

Blood samples were collected from patients with leukemia(n=150) or lymphoma(n=150) in the Cancer Hospital from March to September 2014. The specific antibodies(IgG, IgM)to, and circulating antigens(CAg) of Toxoplasma gondii were determined by ELISA. A 529 bp specific sequence was amplified by PCR from the genomic DNA of T. gondii. T. gondii-specific IgG positive rate in patients with leukemia and lymphoma were 16.0%(24/150) and 20.0%(30/150), respectively, which were significantly higher than that of healthy persons(6.4%, 7/110)(P<0.05). IgM positive rate of the leukemia patients, lymphoma patients, and healthy persons was 2.7%(4/150), 1.3%(2/150), and 0.9%(1/110)(P>0.05), respectively. No significant difference was found in IgM and CAg positive rate among leukemia patients, lymphoma patients, and healthy persons (P>0.05). No specific band (529 bp) was detected in all samples.
