Abstract

PURPOSE:To report the first live birth after frozen-thawed ovarian transplantation in Turkey and the second case for an acute lymphoblastic leukemia (ALL) survivor in the world. METHODS:A 19-year-old patient underwent ovarian tissue cryopreservation (OTC) before cord blood transplantation in 2010. She was diagnosed as ALL with a bone marrow biopsy revealing 90% blast ALL-L2 type, and karyotype analyses indicated reciprocal translocation at t(9;22)(q34;q11). The patient received the Berlin-Frankfurt-Munster (BFM) protocol, and complete remission was achieved before fertility preservation. Serum AMH level was measured as 1.5 ng/ml, and 12 antral follicles were counted on ultrasound. She was informed about fertility preservation options and decided to proceed with OTC, with her signed consent before cord blood transplantation in April 2011. Ovarian tissue transplantation (OTT) was performed in 2017 when the patient was menopausal with serum FSH levels > 100 IU/ml and estradiol < 20 pg/ml and hematologically in molecular remission. Detailed molecular analysis, standard histology, and immunohistochemistry demonstrated that the thawed tissue is free of malignant cells. RESULTS:Six months following OTT, she had spontaneous menstruation with serum FSH 11 IU/ml and estradiol 53 pg/ml. Two consecutive IVF cycles yielded three top-quality embryos. Following three embryo transfer cycles, one fresh and two frozen, a healthy term live birth was achieved. Frozen-thawed-transplanted tissues were extracted during caesarean delivery upon the patient's request after a total period of 25 months in vivo, and histopathological evaluation revealed that the tissue was free of leukemic infiltration. CONCLUSION:The authors report the first pregnancy and live birth in Turkey and the second live birth in the world following transplantation of frozen-thawed ovarian tissue in a leukemia survivor. As the transplanted tissues were removed during caesarean delivery, histological findings prove the functionality and the malignant-free status of the transplanted tissue during the grafted period.

摘要

目的: 报道土耳其冻融卵巢移植后的第一次活产和世界上第二例急性淋巴细胞白血病 (ALL) 幸存者。 方法: 1 例 19 岁患者,2010 年行脐血移植前卵巢组织冷冻保存 (OTC)。她被诊断为 ALL,骨髓活检显示 90% blast ALL-L2 型,染色体核型分析表明 t(9;22)(q34;q11) 易位。患者接受了柏林-法兰克福-明斯特 (BFM) 方案,在保留生育能力之前达到完全缓解。测定血清 AMH 水平为 1.5 ng/ml,超声计数 12 个窦卵泡。她被告知生育保存选项,并决定继续使用 OTC,并在 2011 年 4 月脐带血移植前签署同意书。2017 年行卵巢组织移植 (OTT),患者绝经后血清 FSH 水平> 100 IU/ml,雌二醇 <20 pg/ml,血液学处于分子缓解状态。详细的分子分析、标准组织学和免疫组织化学证明解冻后的组织无恶性细胞。 结果: OTT 术后 6 个月自主月经,血清 FSH 11 IU/ml,雌二醇 53 pg/ml。连续两个 IVF 周期产生了三个高质量的胚胎。经过 3 个胚胎移植周期,1 个新鲜,2 个冷冻,实现了健康足月活产。在体内总共 25 个月后,应患者要求在剖腹产期间提取冻融移植组织,组织病理学评价显示组织无白血病浸润。 结论: 作者报道了一名白血病幸存者在冻融卵巢组织移植后在土耳其第一次怀孕和活产,以及世界上第二次活产。由于在剖腹产期间移植组织被移除,组织学结果证明了移植组织在移植期间的功能性和无恶性状态。

METHODS:BACKGROUND:Controlled ovarian stimulation (COS) has a negative effect on the endometrial receptivity compared with natural menstrual cycle. Whether it's necessary to postpone the first frozen embryo transfer (FET) following a freeze-all strategy in order to avoid any residual effect on endometrial receptivity consequent to COS was inconclusive. OBJECTIVE:The purpose of this retrospective study was to explore whether the delayed FET improve the live birth rate and neonatal outcomes stratified by COS protocols after a freeze-all strategy. METHODS:A total of 4404 patients who underwent the first FET cycle were enrolled in this study between April 2014 to December 2017, and were divided into immediate (within the first menstrual cycle following withdrawal bleeding) or delayed FET (waiting for at least one menstrual cycle and the transferred embryos were cryopreserved for less than 6 months). Furthermore, each group was further divided into two subgroups according to COS protocols, and the pregnancy and neonatal outcomes were analyzed between the immediate and delayed FET following the same COS protocol. RESULTS:When FET cycles following the same COS protocol, there was no significant difference regarding the rates of live birth, implantation, clinical pregnancy, multiple pregnancy, early miscarriage, premature birth and stillbirth between immediate and delayed FET groups. Similarly, no significant differences were found for the mean gestational age, the mean birth weight, and rates of low birth weight and very low birth weight between the immediate and delayed FET groups. The sex ratio (male/female) and the congenital anomalies rate also did not differ significantly between the two FET groups stratified by COS protocols. CONCLUSION:Regardless of COS protocols, FET could be performed immediately after a freeze-all strategy for delaying FET failed to improve reproductive and neonatal outcomes.

METHODS:OBJECTIVE:To evaluate the effect of oral diosmin on the incidence and severity of ovarian hyperstimulation syndrome (OHSS) and explore the value of diosmin in preventing and treating OHSS. METHOD:A retrospective study of women attending a reproductive center in Guangzhou, China, between September and December 2016. The inclusion criterion was previous cancellation of embryo transfer after oocyte retrieval during IVF owing to a high risk of OHSS. The women were divided into two groups depending on whether they received oral diosmin (1000 mg twice daily for 10 days) after oocyte retrieval (diosmin group) or not (control group). Apart from diosmin, both groups underwent the same treatment. Baseline information and data related to OHSS were compared. RESULTS:Overall, 146 women were included: 74 in the diosmin group and 72 in the control group. The incidence of moderate-to-severe OHSS in the diosmin and control groups was 5/74 (6.2%) and 14/72 (13.4%), respectively (P=0.027). The control group included four cases of paracentesis due to ascites; there were no cases of paracentesis or severe OHSS in the diosmin group. CONCLUSION:Oral administration of diosmin effectively reduced both the incidence of moderate-to-severe OHSS and the severity of OHSS among high-risk women.

METHODS::Recurrent implantation failure (RIF) remains a clinical dilemma. Helium-Neon (He-Ne) laser irradiation has recently become more popular under certain clinical conditions. Given the unique therapeutic effects, we were interested in determining whether pretreatment with He-Ne laser irradiation prior to frozen-thawed embryo transfer (FET) would improve the microcirculation and cause the release of growth factors and cytokines, thus improving endometrial receptivity and the clinical pregnancy rates. Patients chose for themselves whether to proceed with (n = 29) or without (n = 31) pretreatment with He-Ne laser irradiation prior to FET. The clinical pregnancy rate (37.9%) and implantation rate (20.3%) were higher in the laser-treatment group than in the control group (35.5% and 15.9%, respectively, p = .844 and .518, respectively). The live birth rate was higher in the laser-treatment group (27.6% vs. 25.8%, respectively, p = .876) and the miscarriage rate was lower in the laser-treatment group (18.2% and 27.3%, respectively, p = .611). No side effects or complications from laser irradiation were encountered in patients who received the laser treatment. We concluded that pretreatment with He-Ne laser prior to FET may be an alternative choice for RIF-affected women; however, additional well-designed prospective studies are necessary to determine the precise clinical value of this treatment.
