  • Attitudes toward preimplantation genetic testing for aneuploidy among patients with recurrent pregnancy loss in Japan., Eri Takeda, Mayumi Sugiura-Ogasawara, Takeshi Ebara, Tamao Kitaori, Shinobu Goto, Hiroyuki Yoshihara, Takeshi Sato, The journal of obstetrics and gynaecology research,   2020年02月07日, 査読有り, AIM: To examine attitudes toward preimplantation genetic testing for aneuploidy (PGT-A) in patients with recurrent pregnancy loss (RPL) because it has been performed worldwide in spite of little evidence regarding whether it can improve the live birth rate and prevent miscarriage. There has been no study to examine attitudes toward PGT-A in patients with RPL. METHODS: We conducted a cross-sectional study that used a questionnaire to examine attitudes toward PGT-A, the desire for PGT-A and the factors associated with this desire in 386 patients with RPL between November 2014 and January 2019. RESULTS: Overall, 25.1% of patients desired PGT-A and 35.2% answered that they knew about it. Regarding the reasons for wanting PGT-A, 42.3% thought that it would insure a live birth and with complete case analysis, showed that the patients' wish for PGT-A as a means of giving live birth was affected by their IVF-ET history (adjusted odds ratio 2.7, 95% CI 1.2-7.2) and whether they had any knowledge of PGT-A (2.4, 1.1-5.3). Those with a higher total family income (3.5, 1.2-10.1) and a previous IVF-ET (4.6, 2.0-10.3) tended to want PGT-A as a means of avoiding miscarriage. CONCLUSION: The majority had no opinion or a poor knowledge of PGT-A. More patients who self-assessed as knowing about PGT-A or who had undergone IVF-ET had the above type of misunderstanding. Accurate and up-to-date information from facilities different from those in which PGT-A is performed is necessary before reaching a decision on PGT-A.

  • Clinical utility of decorin in follicular fluid as a biomarker of oocyte potential, Yuki Sawada, Takeshi Sato, Chieko Saito, Fumiko Ozawa, Yasuhiko Ozaki, Mayumi Sugiura-Ogasawara, Reproductive Biology, 18, 33 - 39,   2018年03月, 査読有り, © 2017 Society for Biology of Reproduction & the Institute of Animal Reproduction and Food Research of Polish Academy of Sciences in Olsztyn This study investigated the concentration of decorin (DCN) in mature follicular fluid and the existence in the granulosa cells. It also investigated whether DCN is useful as a biomarker for outcomes of assisted reproductive technology (ART). A retrospective cohort study was performed involving 130 oocytes of 88 patients treated with ART because of unexplained infertility. The concentration of DCN in the follicular fluid (F-DCN) was 39.26 ng/ml (median value); it was higher than that in serum. F-DCN of the oocytes fertilized by intracytoplasmic sperm injection (ICSI) was significantly lower than that of oocytes that were not fertilized (33.24 ng/ml vs 40.18 ng/ml; P = 0.043). When a cut-off level of 34.5 ng/ml was set according to the receiver-operating characteristic curve, the fertilization rate of the oocytes from the follicles in which F-DCN was lower than the cut-off level tended to be good compared to that of the oocytes with F-DCN higher than the cut-off level (P = 0.052). DCN is less likely to be produced by the granulosa cells (GCs), because it was not detected in GCs by immunostaining and Western blot analysis. F-DCN has a possibility to be a biomarker indicating the quality of oocytes collected from the corresponding follicle.
  • Preimplantation genetic diagnosis and natural conception: A comparison of live birth rates in patients with recurrent pregnancy loss associated with translocation, Shinichiro Ikuma, Takeshi Sato, Mayumi Sugiura-Ogasawara, Motoi Nagayoshi, Atsushi Tanaka, Satoru Takeda, PLoS ONE, 10,   2015年06月, 査読有り, © 2015 Ikuma et al. This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited. Background: Established causes of recurrent pregnancy loss (RPL) include antiphospholipid syndrome, uterine anomalies, parental chromosomal abnormalities, particularly translocations, and abnormal embryonic karyotypes. The number of centers performing preimplantation genetic diagnosis (PGD) for patients with translocations has steadily increased worldwide. The live birth rate with PGD was reported to be 27-54%. The live birth rate with natural conception was reported to be 37-63% on the first trial and 65-83% cumulatively. To date, however, there has been no cohort study comparing age and the number of previous miscarriages in matched patients undergoing or not undergoing PGD. Thus, we compared the live birth rate of patients with RPL associated with a translocation undergoing PGD with that of patients who chose natural conception. Methods and Findings: After genetic counseling, 52 patients who desired natural conception and 37 patients who chose PGD were matched for age and number of previous miscarriages and these comprised the subjects of our study. PGD was performed by means of fluorescence in situ hybridization analysis. The live birth rates on the first PGD trial and the first natural pregnancy after ascertainment of the carrier status were 37.8% and 53.8%, respectively (odds ratio 0.52, 95% confidence interval 0.22-1.23). Cumulative live birth rates were 67.6% and 65.4%, respectively, in the groups undergoing and not undergoing PGD. The time required to become pregnancy was similar in both groups. PGD was found to reduce the miscarriage rate significantly. The prevalence of twin pregnancies was significantly higher in the PGD group. The cost of PGD was $7,956 U.S. per patient. Conclusions: While PGD significantly prevented further miscarriages, there was no difference in the live birth rate. Couples should be fully informed of the similarity in the live birth rate, the similarity in time to become pregnancy, the advantages of PGD, such as the reduction in the miscarriage rate, as well as its disadvantages, such as the higher cost, and the advantages of a natural pregnancy, such as the avoidance of IVF failure. The findings presented here should be incorporated into the genetic counseling of patients with RPL and carrying a translocation.
  • Comparison of follicular fluid and serum anti-Mullerian hormone levels as predictors of the outcome of assisted reproductive treatment, Yukio Hattori, Takeshi Sato, Hideki Okada, Chieko Saito, Mayumi Sugiura-Ogasawara, EUROPEAN JOURNAL OF OBSTETRICS & GYNECOLOGY AND REPRODUCTIVE BIOLOGY, 169, (2) 252 - 256,   2013年07月, 査読有り, Objective: To compare follicular fluid and serum concentrations of anti-Mullerian hormone (AMH) as predictors of the outcome of assisted reproduction. Study design: This observational study enrolled 58 women who were undergoing IVF or ICSI treatment with the long stimulation protocol. Patients diagnosed as having PCOS were excluded. Serum and follicular fluid AMH levels were assessed as predictors of clinical pregnancy. Results: Both the serum and follicular fluid AMH levels were higher in the clinical pregnancy group than in the failed group. A significant correlation was found between the serum and follicular fluid AMH levels, but a discrepancy was observed in some patients with elevated AMH levels in the follicular fluid or serum alone. Assisted reproductive treatment resulted in clinical pregnancy in all of the patients with elevated AMH levels in the follicular fluid (>40 pM) or in the serum (>10 pM). The ROC-AUC for the combination of follicular and serum AMH was 0.772, which was relatively higher than that for either the serum AMH (AUC: 0.691) or follicular fluid AMH (AUC: 0.688) alone. Conclusion(s): Elevated AMH levels in either the serum or follicular fluid appeared to be predictive of clinical pregnancy, even if AMH levels in other fluids were low. This is a pilot study with preliminary data that need further confirmation. (C) 2013 Elsevier Ireland Ltd. All rights reserved.

  • The polycystic ovary syndrome does not predict further miscarriage in Japanese couples experiencing recurrent miscarriages, Mayumi Sugiura-Ogasawara, Takeshi Sato, Nobuhiro Suzumori, Tamao Kitaori, Kyoko Kumagai, Yasuhiko Ozaki, American Journal of Reproductive Immunology, 61, 62 - 67,   2009年01月, 査読有り, Problem: It has been a matter of controversy whether the polycystic ovary syndrome (PCOS) is actually a causal factor of miscarriages because of the absence of internationally established criteria. We, therefore, in this study investigated whether PCOS and a polycystic ovary (PCO) morphology have predictive value for subsequent miscarriages using new International and Japanese criteria. Method of study: A total of 195 patients with a history of two consecutive first trimester miscarriages and without abnormal chromosomes in either partner, antiphospholipid antibodies or uterine anomalies, were examined. The prospective pregnancy outcome was compared between patients with and without PCOS, PCO morphology, elevated luteinizing hormone (LH), hyperandrogenism and obesity. Results: Of a total of 195 patients, 56 (28.7%) miscarried subsequently. Three (1.5%) and 12 (6.2%) were diagnosed as suffering from PCOS by Japanese and International criteria respectively. There was no relation between a diagnosis of PCOS, PCO morphology, elevated LH, free testosterone or obesity and the subsequent miscarriage rate. Conclusions: A routine test for diagnosis of PCOS is not necessary in patients experiencing recurrent miscarriages because none of the related parameters examined in this study predicted subsequent miscarriage. © 2009 John Wiley & Sons A/S.
  • Occasional antiphospholipid antibody positive patients with recurrent pregnancy loss also merit aspirin therapy: A retrospective cohort-control study, Mayumi Sugiura-Ogasawara, Yasuhiko Ozaki, Tamao Nakanishi, Takeshi Sato, Nobuhiro Suzumori, Kyoko Kumagai, American Journal of Reproductive Immunology, 59, 235 - 241,   2008年03月, 査読有り, Problem: It is well known that treatment with aspirin plus heparin is effective for patients with antiphospholipid syndrome (APS) to prevent pregnancy loss. However, it is unclear if occasional antiphospholipid antibodies (aPL) are a risk factor and whether patients with aPL at one time point but not diagnosed as APS should be treated. Methods of study: We therefore studied whether aspirin alone is effective in patients with occasional aPL who did not meet the criteria for APS. We compared live birth rates between 52 patients with occasional aPL treated with aspirin and 672 unexplained patients with no medication. Patients in both group had a history of two or three pregnancy losses. Results: In all, 44 of 52 patients (84.6%) with occasional aPL could experience live birth when treated with aspirin alone. 509 of 672 patients (75.7%) with unexplained pregnancy losses could have babies. When miscarriage cases caused by an abnormal embryonic karyotype were excluded, the success rates were 95.7% (44/46) and 81.2% (509/621), respectively. The live birth rate in patients with occasional aPL treated with aspirin was significantly higher than that in unexplained patients with no medication (P = 0.008). Conclusion: We therefore conclude that aspirin is also useful in patients with occasional aPL but not APS. © Journal compilation © 2008 Blackwell Munksgaard.
  • Meiotic segregation analysis in male translocation carriers by using fluorescent in situ hybridization, N. Nishikawa, T. Sato, N. Suzumori, S. Sonta, K. Suzumori, K. Suzumori, International Journal of Andrology, 31, 60 - 66,   2008年02月, 査読有り, Balanced reciprocal and Robertsonian translocations are the most common structural chromosome abnormalities in humans, with incidences of 0.7 and 1.23 per 1000. These translocations can affect fertility and/or pregnancy outcome because of possibly impaired production of gametes with an unbalanced zygote caused by the parental arrangement. Fertility problems in male translocation carriers are because of various degrees of sperm alterations that are directly related to the disturbance of the meiotic process. Investigation of human sperm chromosomes was performed by karyotyping spermatozoa after penetration of zona-free hamster oocytes, karyotype analysis now being possible to analyse the segregation patterns by using fluorescent in situ hybridization (FISH). Here, we document the results of meiotic segregation analysis for four Robertsonian and four reciprocal translocation carriers by FISH. In the sperm of Robertsonian translocation males, the majority of spermatozoa were normal/balanced. On the other hand, males with reciprocal translocations demonstrated a high rate of unbalanced spermatozoa of about 50% on meiotic segregation, with an unusually high rate (23.5%) of 3 : 1 segregation. This knowledge can be used for genetic counselling of families with these types of translocations. © 2007 The Authors.
  • Successful pregnancy after artificial insemination in a case of human seminal plasma allergy, Aiko Makino, Takeshi Sato, Yukio Hattori, Chieko Saito, Mayumi Sugiura-Ogasawara, Chiyo Saito, Yoichi Shintani, Reproductive Medicine and Biology, 7, 119 - 122,   2008年01月, 査読有り, Human seminal plasma allergy in women is uncommon, but causes a variety of serious reactions, including urticaria, dyspnea and vomiting, in those that are affected. Semen barriers, such as condoms, are the most widely advocated method for avoiding these reactions. However, this is not acceptable to couples who wish to have children. We present a case of a woman with human seminal plasma allergy who became pregnant after the eighth cycle of artificial insemination using washed sperm from her spouse. © Journal compilation © 2008 Japan Society for Reproductive Medicine.
  • Uterine cervical inflammatory cytokines, interleukin-6 and-8, as predictors of miscarriage in recurrent cases, Yukio Hattori, Tamao Nakanishi, Yasuhiko Ozaki, Kyoko Nozawa, Takeshi Sato, Mayumi Sugiura-Ogasawara, AMERICAN JOURNAL OF REPRODUCTIVE IMMUNOLOGY, 58, (4) 350 - 357,   2007年10月, 査読有り, Problem: Inflammatory changes frequently occur in cases of second trimester miscarriage or pre-term delivery, but little attention has been paid to this association with recurrent miscarriage. As interleukin-6 and interleukin-8 are inflammatory cytokines reported to be associated with bacterial vaginosis, intrauterine infections, and pre-term delivery, we here investigated whether they might have predictive value for spontaneous abortion in recurrent cases. Method of study: Cervical mucus and sera were collected at 4-5 weeks' gestation from a total of 59 patients with a history of two or more unexplained consecutive first trimester miscarriages, and examined by enzyme-linked immunosorbent assay. Patients then were followed up without medication and their pregnancy outcomes were compared with the test results. Results: Of a total of 59 patients, 13 (22%) miscarried subsequently. Both IL-6 and IL-8 in cervical mucus were significantly higher in patients who miscarried subsequently than in those who had a live birth. In addition, there was no correlation between cervical mucus and serum concentrations of IL-6 and IL-8 take at the same time, and there was no relation with serum IL-6 and IL-8 levels between the two groups. Conclusion: Cervical IL-6 and IL-8 might have predictive value for cases of recurrent miscarriage.

  • Elevated aldosterone in amniotic fluid and maternal blood has diagnostic potential in pregnancies complicated with a fetus of Bartter syndrome, T Nakanishi, N Suzumori, H Mizuno, K Suzuki, T Sato, M Tanemura, Y Suzuki, K Suzumori, FETAL DIAGNOSIS AND THERAPY, 20, (6) 481 - 484,   2005年, 査読有り, Pregnancies with fetuses affected with the Bartter syndrome, an autosomal recessive disorder of hyperreninism and hyperaldosteronism, are complicated by early onset of polyhydramnios which results in preterm deliveries. We have assessed biochemical changes in amniotic fluid and the mother's blood with a view to early diagnosis. Aldosterone levels of both amniotic fluid and the mother's blood were found to be increased at 27 weeks of gestation, while electrolyte levels did not differ significantly from those reported earlier for controls. After birth the baby suffered from polyuria with hyponatremia, hypomagnesemia and hypercalciuria which could be controlled by treatment with sodium chloride and magnesium. Elevated aldosterone thus might be a useful marker for early diagnostic purposes. Copyright (c) 2005 S. Karger AG, Basel.

  • Poor prognosis of recurrent aborters with either maternal or paternal reciprocal translocations, M Sugiura-Ogasawara, Y Ozaki, T Sato, N Suzumori, K Suzumori, FERTILITY AND STERILITY, 81, (2) 367 - 373,   2004年02月, 査読有り, Objective: To determine whether the miscarriage rate in recurrent miscarriage patients with an abnormal karyotype, especially reciprocal translocations, in either partner is worse than without an abnormal karyotype. Design: Retrospectively analyzed prospectively obtained database. Setting: Nagoya City University Hospital. Patient(s): One thousand and two hundred eighty-four couples with a history of 2 or more (2 to 12) consecutive first-trimester miscarriages. Intervention(s): Patients with antiphospholipid antibodies were treated with low-dose aspirin and combined therapy. Main Outcome Measure(s): Subsequent miscarriages were compared for cases with and without an abnormal karyotype in either partner. A karyotype analysis was also conducted for each aborted conceptus and offspring of 95 pregnancies of 47 patients with reciprocal translocations. Result(s): Of the total of 1,284 couples, 58 (4.5%) had translocations, 11 being Robertsonian translocations. Eleven of the 18 cases (61.1%) where the husband had a reciprocal translocation suffered further miscarriage; this also was the case for 21 of the 29 cases (72.4%) where the wives had a reciprocal translocation. Those with reciprocal translocations in either partner miscarried significantly more frequently than those without an abnormal karyotype. Only one infant with an unbalanced translocation was found in 34 cases of successful pregnancy following habitual abortion. Conclusion(s): The pregnancy prognosis with either maternal or paternal reciprocal translocations is poorer than without them. The presence of a reciprocal translocation is thus a risk factor in couples who have recurrent miscarriages. (C)2004 by American Society for Reproductive Medicine.
  • Reduction of pleural effusion by OK-432 in a fetus complicated with congenital hydrothorax, A Tsukihara, M Tanemura, Y Suzuki, T Sato, T Tanaka, K Suzumori, FETAL DIAGNOSIS AND THERAPY, 19, (4) 327 - 331,   2004年, 査読有り, A 29-year-old, primiparous woman was referred to our hospital at 21 weeks of gestation because of right pleural effusion in the fetus shown by routine ultrasonographic examination. Cytology revealed abundant lymphocytes, suggesting chylothorax. We removed the pleural effusion and injected OK-432 into the chest cavity at 24 and 25 weeks of gestation. Pleural effusion declined and an adhesion between the lung surface and the pleural membrane seemed to form. At 33 weeks of gestation, a female infant was born by cesarean section (1,090 g and Apgar score 6/8). Although she demonstrated slight retraction and tachypnea, management could be achieved by administration of oxygen alone without mechanical ventilation. Later, the baby was diagnosed as suffering from the Cornelia de Lange syndrome with characteristic features. OK-432 injections could thus prevent complications of chylothorax and hypoplastic lungs, without injury to either the baby or the mother. Copyright (C) 2004 S. Karger AG, Basel.
  • Characteristic findings for diagnosis of baby complicated with both the VACTERL association and duodenal atresia, E Fujishiro, Y Suzuki, T Sato, S Kondo, M Miyachi, K Suzumori, FETAL DIAGNOSIS AND THERAPY, 19, (2) 134 - 137,   2004年, 査読有り, The VACTERL [vertebral defects (V), anal atresia (A), cardiac anomaly (C), tracheal-esophageal fistula with esophageal atresia (TE), renal defects (R), and radial limb dysplasia (L)] association can sometimes be diagnosed by ultrasonography and magnetic resonance imaging (MRI). Although the preaxial limb anomalies on ultrasonography were strongly associated with VACTERL association, the rate of limb anomalies is low. On ultrasonography, useful findings for prenatal diagnosis are a combination of esophageal atresia with hydramnion and renal anomalies. If esophageal atresia cannot be detected due to masking, diagnosis may be very difficult. In this case report, we reported the VACTERL association along with duodenal atresia. The detection of characteristic findings (enlarged stomach and duodenum, possibly change in gallbladder) by use of ultrasonography and MRI might be useful for the prenatal diagnosis of such cases.

  • Examination of fetal cells and cell-free fetal DNA in maternal blood for fetal gender determination, XX Zhao, N Suzumori, Y Ozaki, T Sato, K Suzumori, GYNECOLOGIC AND OBSTETRIC INVESTIGATION, 58, (1) 57 - 60,   2004年, 査読有り, Background: To assess applicability of noninvasive methods for prenatal sex determination, both intact fetal cells and cell-free DNA from maternal blood were studied. Methods: Maternal peripheral blood samples were obtained from 41 women carrying chromosomally normal fetuses and from 3 women with aneuploid fetuses (47, XX,+18; 47, XY,+18 and 47, XY,+21) at 9-22 weeks of gestation. DNA was extracted from the plasma fraction and analyzed by the nested polymerase chain reaction (PCR) using Y chromosome specific primers. After fetal cells were enriched by MACS, fluorescence in situ hybridization (FISH) with chromosome X and Y specific probes was performed to detect XY cells. Results: Although Y-chromosome-specific DNA was detected by PCR analysis in all maternal plasma samples with male fetuses, 26% women bearing female fetuses also gave positive results. By FISH analysis, XY cells were detected in not only 58% of women bearing male fetuses, but also 13% of their counterpoints with female fetuses. Conclusions: Our findings suggested that consistent results for fetal gender using PCR or FISH cannot be obtained with intact fetal cells and cell-free DNA present in maternal blood and plasma at 9-22 weeks of gestation, despite their apparent abundant presence.

  • Use of aspirin and low-molecular-weight heparin to prevent recurrence of maternal floor infarction in women without evidence of antiphospholipid antibody syndrome, A Makino, Y Suzuki, T Yamamoto, T Sato, K Kojima, K Suzumori, FETAL DIAGNOSIS AND THERAPY, 19, (3) 261 - 265,   2004年, 査読有り, During pregnancy, maternal floor infarction (MFI) and massive perivillous fibrin deposition (MFD) often cause fetal growth restriction and death, both being markedly increased by occlusion of the maternal intravenous circulation. Incident rates have been reported to be in the range of 0.09 - 0.5% and recurrent MFI/MFD might be more frequent in early-onset cases. Thus, prevention measures are necessary for high-risk women who have had MFI/MFD as complications in a previous pregnancy. In this report, the use of oral low-dose aspirin at the early trimester and low-molecular-weight heparin drip infusion from the mid-second trimester was examined for this purpose.

  • Cardiac failure caused by severe pre-eclampsia with placental abruption, and its treatment with anti-hypertensive drugs, K Aoyama, Y Suzuki, T Sato, T Yamamoto, K Kojima, T Usami, N Ohte, K Suzumori, JOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH, 29, (5) 339 - 342,   2003年10月, 査読有り, Pre-eclampsia is the abnormality of blood circulation in late pregnancy, often caused by renal failure, hemolysis, elevated liver enzyme, low platelet syndrome, and eclampsia. We present a case of severe pre-eclampsia with placental abruption in a 24-year-old woman, pregnant for the first time. The patient was diagnosed with congestive heart failure, which came as a result of pre-eclampsia. Anti-hypertensive drugs were used for its treatment.

  • Conservative treatment by angiographic artery embolization of an 11-week cervical pregnancy after a period of heavy bleeding, N Suzumori, K Katano, T Sato, J Okada, T Nakanishi, D Muto, Y Suzuki, K Ikuta, K Suzumori, FERTILITY AND STERILITY, 80, (3) 617 - 619,   2003年09月, 査読有り, Objective: To describe a rare case of conservative treatment of an 11-week cervical pregnancy after a period of heavy bleeding. Design: Case report. Setting: A university hospital. Patient(s): A 33-year-old woman was admitted to our hospital for treatment of a cervical pregnancy. Two-and-a-half years thereafter, she gave birth to a healthy baby by vaginal delivery at 38 weeks of gestation. Intervention(s): Systemic methotrexate treatment, ligation of descending branches of uterine arteries, cervical cerclage, and unilateral internal iliac artery embolization. Main Outcome Measure(s): Transvaginal ultrasound, magnetic resonance imaging, and arteriography findings. Result(s): The patient was successfully treated with unilateral internal iliac artery embolization on the same side as the pregnancy in the 11th gestational week. Conclusion(s): After failed methotrexate and vessel ligation in cervical pregnancy, unilateral internal iliac artery embolization is an effective and conservative treatment that allows preservation of reproduction potential.

  • Comparison between fluorescence in situ hybridization (FISH) and quantitative-fluorescent polymerase chain reaction (QF-PCR) for the detection of aneuploidies in single blastomeres, T Sato, K Ikuta, J Sherlock, M Adinolfi, K Suzumori, PRENATAL DIAGNOSIS, 23, (8) 678 - 684,   2003年08月, 査読有り, Objectives The aim of our investigation was to compare the efficiencies of the fluorescence in situ hybridization (FISH) and the quantitative-fluorescent PCR (QF-PCR) methods for the detection of sexing and numerical chromosome disorders in single blastomeres collected from the same preimplantation human embryos. Methods FISH analysis was carried out on 145 blastomeres from the 79 surplus embryos with probes specific for chromosomes 13, 18, 21, X, and Y. QF-PCR was performed with each one or two of the primers specific for the same chromosomes on 151 blastomeres from the same embryos obtained from patients undergoing IVF treatment. Results Analyses were possible on 135 blastomeres (93%) by FISH and on 117 blastomeres (77%) by QF-PCR. Of 65 embryos, which could be analyzed by both methods, 20 embryos (31%) were diagnosed as abnormal. Conclusion The present study shows that FISH tests are more accurate than QF-PCR assays for the detection of numerical chromosome disorders when performed on single blastomeres.

  • Prenatal diagnosis of triple X using fetal cells obtained by endocervical lavage, XX Zhao, K Suzumori, T Sato, PRENATAL DIAGNOSIS, 23, (7) 549 - 551,   2003年07月, 査読有り, Prenatal diagnosis of aneuploidies currently relies on invasive procedures such as chorionic villous sampling and amniocentesis. These methods can provide an accurate diagnosis of the fetal karyotype but are relatively invasive. Here, we report a case of the prenatal detection of triple X using fetal cells obtained by lavage of the endocervical canal prior to amniocentesis, following ultrasound diagnosis of hydrops fetalis.

  • Gonadotropins and cytokines affect luteal function through control of apoptosis in human luteinized granulosa cells, Hirokazu Matsubara, Hirokazu Matsubara, Katsuo Ikuta, Yasuhiko Ozaki, Yuka Suzuki, Noritaka Suzuki, Takeshi Sato, Kaoru Suzumori, Journal of Clinical Endocrinology and Metabolism, 85, 1620 - 1626,   2000年01月, 査読有り, The luteal phase in the normal human menstrual cycle is known to be about 14 days. The physiological mechanisms that regulate the corpus luteum remain to be clarified, although apoptosis is reported to be involved. This study was undertaken to investigate the regulation of luteal function by gonadotropins, cytokines, and PGs, concentrating attention on the incidence of apoptosis and its molecular mechanisms in cultured human luteinized granulosa cells collected at oocyte pick-up from patients undergoing in vitro fertilization and embryo transfer. Clusters of granulosa cells were pipetted in 0.1% hyaluronidase in phosphate-buffered saline. After cell separation by centrifugation using Ficoll-Paque, 1 × 104viable cells/mL in RPMI 1640 medium with 10% FCS were used for experimentation. Substances added were FSH (100 ng/mL), hCG (100 ng/mL), LH (100 ng/mL), interleukin-1β (IL-1β; 10 ng/mL), transforming growth factor-β1 (TGFβ1; 10 ng/mL), macrophage colony-stimulating factor (M-CSF; 10 ng/mL), tumor necrosis factor-α (TNFα; 10 ng/mL), and PGF2α(10 ng/mL). After 24-h culture at 37 C under 5% CO2and air, cells were fixed with 4% neutral buffered formalin and stained with Hoechst 33258. Apoptotic bodies were counted under a fluorescence microscope, and immunostaining was performed using anti-Fas, Fas ligand, Bcl-2, Bax, and p53 antibodies. Incidences of apoptotic bodies in the group without substance addition were 0.7 ± 0.2% (0 h), 5.9 ± 0.6% (24 h), and 7.9 ± 1.2% (48 h); spontaneous increase was significant at the latter time points. Defining the incidence at 24 h as 100%, values after treatment were: FSH, 57%; LH, 84%; hCG, 44%; IL-1β, 76%; TGFβ1, 52%; M-CSF, 50%; TNFα, 177%; and PGF2α, 147%. Significant suppression was observed with FSH, hCG, TGFβ1, and M-CSF (P < 0.01). On the other hand, significant induction occurred with TNFα and PGF2α(P < 0.01). On immunostaining, the incidence of stained cells with anti-Fas, Fas ligand, Bax, and p53 antibody was increased after 24-h incubation without addition. This was reduced by hCG, TGFβ1, and M-CSF. No stained cells were observed with anti-Bcl-2 antibody before or after incubation. In conclusion, our results suggest that both gonadotropins (FSH and hCG) and cytokines (TGFβ1 and M-CSF) may be involved in the support of luteal function via suppression of apoptosis, and that TNFα and PGF2αmay contribute to ovarian dysfunction and/or luteal regression via its induction in human luteinized granulosa cells. Our results also suggest that Fas, Fas ligand, p53, and Bax may play roles in this apoptosis controlled by hCG, TGFβ1, and M-CSF.
