To elucidate the association between anticardiolipin antibody (aCL-Ab) or anti-cardiolipin beta-2-glycoprotein I-antibody (aCL-beta-2-GP I-Ab) and recurrent fetal miscarriage, the positive rates of aCL-Ab were assessed in 667 patients with recurrent fetal miscarriages and those of aCL-beta-2-GP I-Ab were assessed in 208 patients. The rates were then compared with the control group. The positive rate of aCL-Ab in the patients group (17.4%) was significantly higher than that in the control group (4.0%). The rate of aCL-Ab was especially high in patients who had experienced two or more fetal miscarriages including at least one or more intrauterine fetal deaths during the second or third trimester (41.3%). The positive rate of aCL-beta-2-GP I-Ab in patients with recurrent fetal miscarriage (3/208 cases, 1.4%) was not significantly different from the control group (0/100 cases, 0%). However, the rate of aCL-beta-2-GP I-Ab was significantly higher in patients who had experienced two or more fetal miscarriages including at least one or more intrauterine fetal deaths during the second or third trimester (8.3%) compared with the control group. In conclusion, the implication of aCL-Ab in the genesis of recurrent fetal miscarriage was confirmed. It was suggested that aCL-beta-2-GP I-Ab was associated with the generation of intrauterine fetal death, although it had little association with the genesis of recurrent fetal miscarriage during the first trimester.
Twelve patients with recurrent abortion who had shown positive antiphospholipid antibodies were treated through the administration of a Japanese modified traditional Chinese herbal medicine Sairei-To (Chan ling-Tang) The patients had experienced a total of 27 spontaneous abortions in their previous pregnancies and had no other pregnancy history except for one patient. The patients were treated with 9.0 g of Sairei-To per day before their next pregnancy. The positive value of antiphospholipid antibodies returned to negative in 9 patients out of 12 patients through the treatment. Out of 12 patients, in 10 patients, their new pregnancy continued uneventfully and delivered an offspring (Success rate: 83.3%). Thus, the current treatment was considered to be an effective therapy for patients with recurrent abortion who were found to be positive for antiphospholipid antibodies.
The polymerase chain reaction-restricted fragment length polymorphism (PCR-RFLP) method was used for both examining compatibility at the HLA-DQB1 gene locus and determining HLA-DQ antigen polymorphism in spouses of unexplained recurrent abortions. Genomic DNA samples were prepared from peripheral mononuclear cells from patient and control couples. Two hundred and thirty base pair fragments of the second exon of the HLA-DQB genes were selectively amplified. Amplified DNAs were digested with the restriction endonucleases, Fok I, Hae III, Hha I, Rsa I and Sau3A I, and subjected to electrophoresis in a polyacrylamide gel. The RFLPs showed that habitual aborters and their husbands had neither significantly frequent alleles nor shared common alleles at the HLA-DQB locus when compared to the control group. Since significant HLA-DQB compatibility was not observed between the spouses and unexplained recurrent aborters, in order to determine whether or not HLA compatibility is responsible for the genesis of unexplained recurrent abortions, it is imperative to further examine the compatibility between other HLA gene loci.
Incarceration of the retroverted uterus is a rare complication of pregnancy and rarely persists until term. The diagnosis is extremely difficult to make and a cesarean section should be performed in such cases. A 33-year-old Japanese woman was admitted at 40 weeks gestation for evaluation of preeclampsia. Vaginal examination revealed that the uterine cervix could hardly be visualized, although the fetal head was impacted in the pelvis. These findings suggested incarceration of the retroverted uterus. Magnetic resonance imaging (MRI) was performed and clarified the exact anatomical relationship and confirmed the diagnosis. She therefore underwent a cesarean section and a male infant weighing 3552 g was delivered with Apgar scores of 9 and 10 at 1 and 5 minutes, respectively. At surgery she was found to have an adhesion between the uterus and the pouch of Douglas. MRI is a useful tool in correctly making the diagnosis of uterine incarceration and facilitates preparation for a cesarean section.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
