孕妇与胎儿巨细胞病毒感染的血清学研究   总被引:7,自引:0,他引:7  
测定了173例孕妇及81例胎儿血清CMV抗体。结果:173例孕妇血清中CMV-IgG阳性率为70.5%(122/173),CMV-IgM阳性率为0.58%(1/173),孕妇早、中、晚孕期CMV感染率分别为52%、72.9%,74.4%,妊娠次数≥4次的孕妇CMV感染率较高。81例脐血血清中CMV-IgG阳性率为54.3%(44/81),CMV-IgM阳性率为6.2%(5/81),5例先天性CMV感染儿分别为4例胎儿畸形及1例产前咨询者,后者取脐血查到IgM阳性后1个月,胎死宫内。提示脐血中一旦查到CMV-IgM阳性,胎儿有严重后果。因此,产前诊断胎儿CMV感染,早期发现CMV感染儿,是非常重要的。  相似文献

Objective.?Low maternal plasma protein Z (PZ) concentrations were reported in patients with pre-eclampsia (PE), a small for gestational age (SGA) neonate, and a fetal demise (FD). Anti-protein Z antibodies (APZ-AB) have been proposed as a possible underlying mechanism leading to low plasma PZ concentrations. The objective of this study was to determine the maternal plasma concentration of APZ-AB in women with a normal pregnancy, and patients with PE, an SGA neonate or a FD.

Study design.?A cross-sectional study included women in the following groups: (1) non-pregnant women (n = 45); and pregnant women with: (2) normal pregnancies (n = 70); (3) PE (n = 123); (4) SGA neonates (n = 51); and (5) a FD (n = 51). Plasma concentrations of anti-protein Z IgM and IgG antibodies were measured by ELISA. Elevated APZ-AB was defined as >75th, 90th and 95th percentile of the normal pregnancy group. Non-parametric statistics were used for analyses.

Results.?(1) Patients with an SGA neonate had a higher median maternal plasma IgG APZ-AB concentration than women with normal pregnancies (p < 0.001), and patients with PE (p < 0.001) or with a FD (p = 0.001). (2) The proportion of patients with a maternal plasma IgM APZ-AB concentration >90th percentile was higher in the SGA group than in the PE group (p = 0.01). (3) Patients with PE maternal plasma IgM APZ-AB concentration >90th percentile had a higher rate of villous thrombosis (p = 0.03) and persistent muscularisation of basal plate arteries (p = 0.01) than those with IgM APZ-AB concentration <90th percentile; and (5) Patients with FD and maternal plasma IgM APZ-AB concentration >90th percentile had a higher rate of umbilical phlebitis and arteritis than those with IgM APZ-AB concentration <90th percentile (p = 0.003).

Conclusions.?(1) Patients with SGA neonates have a higher median plasma concentration of IgG APZ-AB than normal pregnant women, or patients with PE or FD; and (2) maternal plasma IgM APZ-AB concentration >90th percentile was associated with vascular placental lesions in patients with PE, but not in those with an SGA neonate, suggesting that in a subset of patients, these antibodies can be associated with abnormal placentation and pregnancy complications.  相似文献

The presence of elevated titres of anticardiolipin antibodies (ACA) and antihistone antibodies (AHA) in the blood serum is considered as one of serious reasons of repeated pregnancy losses. According to some reports, heparin significantly improves live birth rates in these cases. The aim of the work is an evaluation of the results of the heparin therapy in pregnant women with elevated titres of ACA and/or AHA in blood and bad obstetric anamnesis, or after sterility treatment. Our material consisted of three groups: the first one was composed of 25 ACA- and/or AHA-seropositive pregnant women 30.0 +/- 4.1 years old with 1-5 early miscarriages in past, the second one of six seropositive patients 31.3 +/- 2.8 years old, actually pregnant after the treatment of unexplained sterility (two of them after assisted reproduction) and, finally, in the third group were placed five pregnant ACA- and AHA-seronegative pregnant women 30.8 +/- 2.2 years old with 2-4 abortions of unexplained etiology in past. The ACA IgA, IgM and IgG and AHA IgG levels in blood sera were determined by ELISA. As a positive titre ACA in the class IgA was considered > 7 APL/ml, in the class IgM > 4 MPL/ml, IgG > 7 GPL/ml and in case of AHA IgG > 25 GPL/ml. The patients were treated by heparin 7500-30,000 units daily during all the pregnancy under the control of kaolin-kephalin time. In the first group, where 53 pregnancies from 56 were miscarried (94.6%), after the heparin therapy in 10 women 9 pregnancies of 11 (81.8%) were terminated by live birth (p < 0.001). One of the patients died three days after cesarean section because of myocardial infarction, probably due to sudden stopping of heparin. In the second group three women after heparin treatment delivered live babies, but three untreated aborted. In the last group only two women treated by heparin delivered live babies and three, despite treatment, miscarried. It should be concluded, that heparin therapy in ACA- and/or AHA-positive pregnant women might be a recommended therapeutic method. In cases of antiphospholipid syndrome a special precaution should be undertaken, when stopping the heparin. It seems, that double assay of ACA and AHA in patients with conception troubles might be usefull.  相似文献

Objective

To investigate the association of antibodies to β2-glycoprotein I (anti-β2GPI), cardiolipin (ACA), phosphatidylserine (anti-PS) and prothrombin (anti-PT) with recurrent spontaneous miscarriage (RSM).

Study design

Case–control study involving 277 RSM cases and 288 controls: autoantibody levels were measured by ELISA. Differences between cases and controls were analyzed by nonparametric Mann–Whitney test, and logistic regression was used in analyzing the association of autoantibodies with RSM.

Results

Anti-PS IgG, ACA IgM and IgG, and anti-PT IgM were significantly associated with RSM risk, and differential antibody association was noted according to BMI and primary and secondary RSM. Higher prevalence of elevated anti-PS IgG was seen in cases, with the strongest risk above the 99th percentile. For ACA IgM, 28 cases (10.1%) and 5 controls (1.7%) were positive, with increasing OR for increasing cut-off points, which was significant at antibody titers >99th percentile. For ACA IgG, 101 cases (36.5%) and 13 controls (4.5%) were positive, with graded increase in OR for increasing cut-off points, which was significant at titers >90th percentile (maximal at titers >99th percentile). For anti-PT, 23 cases (12.0%) and 9 controls (6.1%) were positive, with increased OR at titers >90th percentile. Regression analyses confirmed the independent association of anti-PS IgG, ACA IgM and IgG with RSM, and significant RSM risk was associated with high anti-PS IgG (P < 0.001) and ACA IgM (P < 0.001) titers, and a dose-dependent increase in RSM risk was seen with progressively increased ACA IgG titers. No significant association existed between anti-PT IgM and RSM.

Conclusion

Elevated ACA IgM and IgG, and anti-PS IgG antibodies are positively associated with RSM.  相似文献

In 265 Canadian women, with and without tubal factor infertility (TFI), we compared Chlamydia trachomatis cultures of endocervical swabs, endotubal swabs and biopsies, serology, and past history. A history of pelvic inflammatory disease (PID) was absent in 69.2% of TFI women, despite visual evidence of tubal damage. C. trachomatis was not isolated in any of 52 patients with TFI (TFI group), 114 having tubal ligation (STER group), or 99 patients having hysterectomy (HYST group). However, chlamydial antigen was detected with an immunochemical method in 1 of 16 tubal biopsy specimens from TFI women. The prevalence of chlamydial IgM or IgG antibody in serum was significantly higher (P less than 0.0001) in the TFI group (79.1%) than in the other two groups (relative odds, 6.3; 95% confidence interval: 2.5, 16.8). In seropositive (IgG or IgM) subjects, there was a significant (P = 0.003) and strong (relative odds, 5.1; 95% confidence interval: 1.5, 18.1) association between chlamydial IgA antibody and TFI. In women with TFI, there was no significant association between IgM or IgG seropositivity (P = 0.56). or IgA seropositivity (P = 0.53), and a negative history for PID. These findings are consistent with the hypothesis that C. trachomatis is a major cause of TFI following PID, which may or may not be asymptomatic.  相似文献

Our purpose was to determine whether small-for-gestational-age (SGA) fetus can be divided to subclassified groups using fetal Doppler velocimetry. Fifty-four pregnant women with SGA infant delivered after 37 weeks of gestation were studied. After 24 weeks of gestation, fetal middle cerebral artery puslatility index (MCAPI) and umbilical artery pulsatility index (UAPI) were measured at 2- to 3-week intervals using Doppler ultrasound. Perinatal outcomes [operative delivery due to fetal distress, abnormal fetal heart rate (FHR) pattern, meconium staining, low Apgar score (<7), neonatal acidosis (umbilical artery blood pH <7.15), neonatal intensive care unit (NICU) admission due to neonatal asphyxia, and decreased amniotic fluid] were compared in subclassified SGA groups using fetal Doppler velocimetry. The number of SGA fetuses with normal MCAPI and UAPI (normal SGA group) was 39, and those with significantly low MCAPI but normal UAPI (eventful SGA group) 15, respectively. Birth age and birth weights in the eventful SGA group were significantly earlier and lower than those in the normal SGA group, respectively (p < 0.05, and p < 0.005). There were significant increases in operative deliveries, abnormal FHR patterns and decreased amniotic fluid in eventful SGA group, when compared with events related to normal SGA group. However, there were no significant differences in meconium staining of amniotic fluid, low Apgar score, neonatal acidosis, and NICU admission between the two groups. These results suggest that SGA fetus with abnormally low MCAPI but normal UAPI has more poor perinatal outcomes, compared with that with normal MCAPI and UAPI.  相似文献
