本文报告241例孕妇血清中人微小病毒B19-IgM及其他TORCH抗体的检测结果,其中B19-IgM阳性率为7.05%,与蓁四项抗体阳性率比较,均呈显著性差异,表明我地区孕妇中人微小病毒B19较其余四项TORCH因子有着较高的新近感染率,从而提示有必要将B19-IgM列为孕发TORCH监测项目之一。  相似文献

作者用ELISA法检测了105例有上感及皮疹史孕妇和正常孕妇血清中的B19特异性抗体,其结果B19-IgG抗体的总阳性率为33.3%(35/105),表明在我地区存在着B19感染孕妇和B19易感孕妇(B19-IgG抗体阴性者);同时检测的B19-IgM抗体的阳性率为:有上感及皮疹史者是12.9%(9/70),正常孕妇均为阴性(0/35),两者有显著性差异(P<0.05),提示上感及皮疹与B19的新近感染相关,而孕期的B19新近感染可致胎儿水肿死亡。因而我们认为孕期作该病毒监测在保证优生工作中有着重要意义。  相似文献

1971年Nahmias将可造成胎儿垂直感染的几种病原体称为“TORCH”,包括弓形虫(Toxoplasma,TOX),风疹病毒(Rubella Virus,RV),单纯疱疹病毒(Herpes Si mplexVirus,HSV),巨细胞病毒(Cytomaglovirus,CMV)及其它微生物(Others),这些病原体可通过胎盘屏障传播给胎儿,导致流产、早产、胎儿中枢神经发育迟缓、畸形及死胎等,在围产医学中称为“TORCH综合征”。为了解武汉地区孕妇中TORCH的感染情况,以便在孕前和孕期向孕妇提出正确的建议,保证母婴健康,我们对本地区1078例孕妇进行了TORCH抗体水平测定,结果报道如下。1资料与方法1.1研…  相似文献

TORCH感染治疗与否对胎婴儿预后的关系探讨   总被引:14,自引:2,他引:12  
目的:探讨TORCH感染治疗与否与胎婴儿预后的关系。方法:用ELISA结合PCR方法对妊娠6周-20周间检出TORCH感染而不愿终止妊娠的95例孕妇进行治疗后,随访直至分娩,与同期检出TORCH感染而未行治疗的195例中晚期孕妇比较。结果:在妊娠各期TORCH感染情况大致相同,只是各种病原体比例有所差异。继往有感染者,孕期易复发性感染。研究表明:无论在妊娠哪一期感染,均可以发生母婴垂直传播,治疗后并不能减少母婴垂直传播率,对早孕TORCH感染者,虽经积极治疗,队季可改善部分围产儿感染、出血等并发症外,沿不能从根本上纠正出生缺陷及胎婴儿的发育落后。结论:在早孕期间检出TORCH活动性感染者,可考虑胎儿的健康建议终止妊娠。  相似文献

A split-sample study was conducted to evaluate the performances of three enzyme immunoassays (EIAs) utilizing one or more conformational antigens to detect human parvovirus B19 (B19V)-specific immunoglobulin M (IgM) or IgG in the sera of 198 pregnant women. We compared EIAs available from Biotrin International, Inc. (Dublin, Ireland), Medac Diagnostika (Wedel, Germany), and Mikrogen (Martinsried, Germany). Specimens with discordant results were analyzed further using an immunofluorescence assay (Biotrin). Equivocal data accounted for close to half of all the discrepant results for both IgM and IgG, with 7 of 15 discrepant results from the Medac and Mikrogen kits involving equivocal data and the Biotrin kit giving a single equivocal result. For each specimen, a consensus was established from the four test results if agreement occurred among at least three of four results. Overall, the highest percentage of agreement with the consensus results was seen when Biotrin kits were used; 194 (100%) of 194 and 194 (99.5%) of 195 results for IgM and IgG, respectively, agreed with the consensus results. When Medac kits were used, 189 (97.4%) of 194 and 191 (97.9%) of 195 results for IgM and IgG, respectively, agreed with the consensus, and when Mikrogen kits were used, 179 (92.3%) of 194 and 193 (99%) of 195 results for IgM and IgG, respectively, agreed with the consensus. Given the consensus results, the Medac EIA appeared to generate presumed false-positive results for IgM and the Mikrogen EIA appeared to generate presumed false-positive results for IgG and IgM. In summary, the Biotrin EIAs produced far fewer equivocal results than the other assays and results of the Biotrin EIAs agreed more often with the consensus results than did those of the other commercially available EIAs for detecting B19V-specific IgM and IgG antibodies.  相似文献

Sera from inhabitants of Belém, Pará (542 sera), Brazil and of members of 3 Brazilian tribes--Tiriyo/Alto Paru (near Surinam) (212 sera), Xicrin (128 sera), and Mekranoiti (121 sera)--of different age and sex groups were tested for the presence of specific antibody against human parvovirus (B19) (RIA) and rubella virus (latex agglutination test). Parvovirus (B19) IgG was found in 42.6% of the population sample from Belém but in only 4.7 to 10.7% of the members of the tribes. Rubella virus antibody was found in 72.7% of the sera from Belém but approaching a prevalence of 85-90% in age groups above 20 years. In the tribes rubella virus antibody was detected in 36.9 to 72.6% of all sera. There were remarkable sex differences of antibody prevalence in several age groups of the population from Belém and of the tribal populations. About a quarter of the skin rashes in Belém that were not attributable to infections with rubella, measles, or arboviruses were caused by recent B19 infections.  相似文献

Objective: To study parvovirus B19 infection in immunocompromised subjects such as renal transplantation recipients.
Methods: Two cases of B19 infection in renal transplant recipients have been included in the study. The outcome of the infection has been studied by both serologic and virologic methods. A monitoring of the DNAemia was done by a nested PCR in endpoint titration assays.
Results: In one patient with severe anemia an acute B19 infection was diagnosed by PCR 26 days after the transplant; a high level of DNAemia persisted until an intravenous immunoglobulin treatment. Then a sharp decrease of the DNAemia was shown, without full clearance of B19 virus. In a lymphocyte suspension from the organ donor, B19 DNA was detected. In the other patient, who recovered spontaneously from anemia, a persistent B19 infection was demonstrated at day 106 after transplantation and was still demonstrable after 470 days.
Conclusions: A high level of B19 DNAemia was associated with symptomatic infection, with severe anemia, whereas low-level DNAemia was long-lasting in asymptomatic subjects with impaired immunologic responses. The endpoint titration assay by nested PCR was very useful for the monitoring of B19 infection, particularly following the therapeutic intravenous immunoglobulin administration.  相似文献

Development of rapid and sensitive detection methods for group B streptococci (GBS) in pregnant women remains useful in order to adequately identify pregnant women at risk of transferring GBS to their neonate. This study compared the CDC recommended sampling and culture method with two qPCR methods for detecting GBS colonization.For a total of 100 pregnant women at 35-37 weeks of gestation, one rectovaginal ESwab each was collected. Eswab medium was inoculated into Lim broth, incubated for 24 h and plated onto chromID™ Strepto B agar (ChromAgar). DNA was extracted with the bioMérieux easyMAG platform, either directly from the rectovaginal ESwab or from Lim broth enrichment culture. Two different qPCR formats were compared, i.e. the hydrolysis probe format (Taqman, Roche) targeting the sip gene and the hybridization probe format (Hybprobe, Roche) targeting the cfb gene.Both qPCR techniques identified 33% of the women as GBS-positive. Only one culture-positive sample was qPCR-negative. QPCR directly on the sample significantly increased the number of women found to be GBS-positive (27%) compared to culture (22%). Moreover, the sensitivity of qPCR after Lim broth enrichment (33%) was again significantly higher than qPCR after DNA extraction directly from the rectovaginal swabs (27%).In conclusion, for prenatal screening of GBS from rectovaginal samples of pregnant women, our results are in accordance with CDC guidelines, which suggest using qPCR after Lim broth enrichment in addition to conventional (culture-based) detection. qPCR after Lim broth enrichment further increased the percentage of GBS-positive women, as detected by direct qPCR, from 27 to 33%, although the bacterial inoculum was low for these subjects.  相似文献

Abstract The main aim of this study was to investigate the genotoxic effect of combined pharmacotherapy applied in post-operative treatment of cervical cerclage in pregnant women over six days. This study included 19 phenotypically healthy pregnant women in mid-trimester with a diagnosis of cervical insufficiency, mean age 28±5.33. The frequency of micronuclei (MN) was estimated in peripheral blood lymphocytes of patients before surgical intervention and after the end of applied pharmacotherapy by application of cytokinesis block micronucleus (CBMN) test. Mean value of baseline MN frequency was 6.84±2.91 MN/1000 binucleated cells, and after the end of the applied therapy, 10.32±4.27 MN/1000 binucleated cells (P<0.001) were found. The data of cell proliferation index showed that the combined therapy did not induce significant difference in cell kinetics (P>0.05). Our results showed that combined pharmacotherapy treatment over six days significantly increased the frequency of MN in peripheral blood lymphocytes of pregnant women.  相似文献
