Reproductive, obstetric, and long-term health outcome after uterus transplantation: results of the first clinical trial.

OBJECTIVE: To evaluate reproductive, obstetric, and long-term health of the first completed study of uterus transplantation (UTx). DESIGN: Prospective. SETTING: University hospital. PATIENT(S): Nine live donor UTx procedures were conducted and seven were successful. Donors, recipients, and children born were observed. INTERVENTION(S): In vitro fertilization was performed with embryo transfer (ET) of day 2 or day 5 embryos in natural cycles. Pregnancies and growth trajectory of the children born were observed. Health-related quality of life, psychosocial outcome, and medical health of donors and recipients were evaluated by questionnaires. MAIN OUTCOME MEASURE(S): The results of in vitro fertilization, pregnancies, growth of children, and long-term health of patients were reported. RESULT(S): Six women delivered nine infants, with three women giving birth twice (cumulative birth rates of 86% and 67% in surgically successful and performed transplants, respectively). The overall clinical pregnancy rate (CPR) and live birth rate (LBR) per ET were 32.6% and 19.6%, respectively. For day 2 embryos, the CPR and LBR per ET were 12.5% and 8.6%, respectively. For day 5 embryos, the CPR and LBR per ET were 81.8% and 45.4%, respectively. Fetal growth and blood flow were normal in all pregnancies. Time of delivery (median in full pregnancy weeks + days [ranges]) by cesarean section and weight deviations was 35 + 3 (31 + 6 to 38 + 0) and -1% (-13% to 23%), respectively. Three women developed preeclampsia and four neonates acquired respiratory distress syndrome. All children were healthy and followed a normal growth trajectory. Measures of long-term health in both donors and recipients were noted to be favorable. When UTx resulted in a birth, scores for anxiety, depression, and relationship satisfaction were reassuring for both the donors and recipients. CONCLUSION(S): The results of this first complete UTx trial show that this is an effective infertility treatment, resulting in births of healthy children and associated with only minor psychological and medical long-term effects for donors and recipients.

Striving for motherhood after uterus transplantation: a qualitative study concerning pregnancy attempts, and the first years of parenthood after transplantation.

STUDY QUESTION: How do women experience attempts to become pregnant, and the first years of motherhood, after uterus transplantation (UTx)? SUMMARY ANSWER: Women who try to become pregnant after UTx experience the general strains typically associated with infertility and childlessness, such as failure of embryo transfer (ET), and specific worries about graft survival but when they become mothers they essentially feel like other mothers, with the associated rewards and stresses. WHAT IS KNOWN ALREADY: UTx has proven to be a successful treatment for absolute uterine factor infertility (AUFI). Although UTx seems to have a positive effect on self-image there is a lack of knowledge about how women who have received uterine grafts experience pregnancy attempts, pregnancy itself and the first years of motherhood. STUDY DESIGN, SIZE, DURATION: This prospective cohort study included the seven participants in the first UTx trial who had experienced surgically successful grafts. Pregnancy was attempted using ET 12 months after transplantation. Structured interviews were performed once a year for 5 years after transplantation. PARTICIPANTS/MATERIALS, SETTING, METHODS: Six of the seven participants (mean age 29.3 years at UTx) had AUFI owing to the congenital absence of the uterus, while the seventh woman had undergone a hysterectomy. Post-transplantation, yearly interviews (2013-2018) were performed, comprising a total of 34 interviews. Interview data were analysed thematically. MAIN RESULTS AND THE ROLE OF CHANCE: All seven participants achieved pregnancy during the study period and six became mothers. Experiencing the previously unimaginable was classed as an overarching theme with the following underlying themes: The yoke of childlessness; Going through the impossible and Motherhood as surreal and normal. The results showed that the women who try to achieve motherhood after UTx generally describe their situation as manageable and present strains comparable to other women undergoing infertility treatments. LIMITATIONS, REASONS FOR CAUTION: The fact that all participants came from one centre is a limitation. WIDER IMPLICATIONS OF THE FINDINGS: There are real psychological strains in motherhood after UTx, such as the concern the women expressed relating to health of the child and the effects of immunosuppressants. These findings are in line with those of other women who became pregnant after transplantation of organs other than the uterus. The results show that extra psychological support and attention should be given to those with repeated pregnancy failures or unsuccessful outcomes. In the cases where women became mothers, attention needs to be given to the possible worries connected to the UTx, but in other respects, they should be treated like any mother-to-be.

Live birth after robotic-assisted live donor uterus transplantation.

INTRODUCTION: The proof-of-concept of uterus transplantation, as a treatment for absolute uterine factor infertility, came with the first live birth after uterus transplantation, which took place in Sweden in 2014. This was after a live donor procedure, with laparotomy in both donor and recipient. In our second, ongoing trial we introduced a robotic-assisted laparoscopic surgery of the donor to develop minimal invasive surgery for this procedure. Here, we report the surgery and pregnancy behind the first live birth from that trial. MATERIAL AND METHODS: In the present study, within a prospective observational study, a 62-year-old mother was the uterus donor and her 33-year-old daughter with uterine absence as part of the Mayer-Rokitansky-Küster-Hauser syndrome, was the recipient. Donor surgery was mainly done by robotic-assisted laparoscopy, involving dissections of the utero-vaginal fossa, arteries and ureters. The last part of surgery was by laparotomy. Recipient laparotomy included vascular anastomoses to the external iliac vessels. Data relating to in vitro fertilization, surgery, follow up, obstetrics and postnatal growth are presented. RESULTS: Three in vitro fertilization cycles prior to transplantation gave 12 cryopreserved embryos. The surgical time of the donor in the robot was 360 minutes, according to protocol. The durations for robotic surgery for dissections of the utero-vaginal fossa, arteries and ureters were 30, 160 and 84 minutes, respectively. The remainder of donor surgery was by laparotomy. Recipient surgery included preparations of the vaginal vault, three end-to-side anastomoses (one arterial, two venous) on each side to the external iliacs and fixation of the uterus. Ten months after transplantation, one blastocyst was transferred and resulted in pregnancy, which proceeded uneventfully until elective cesarean section in week 36+1 . A healthy boy (Apgar 9-10-10) was delivered. Follow up of child has been uneventful for 12 months. CONCLUSIONS: This is the first report of a live birth after use of robotic-assisted laparoscopy in uterus transplantation and is thereby a proof-of-concept of use of minimal invasive surgery in this new type of transplantation.

One uterus bridging three generations: first live birth after mother-to-daughter uterus transplantation.

OBJECTIVE: To determine whether a uterus from the mother of a woman with absolute uterine factor infertility can be transplanted to daughter and carry a pregnancy with delivery of a healthy child. DESIGN: Part of an observational study. SETTING: University teaching hospital. PATIENT(S): Twenty eight-year-old woman with uterine agenesis, her male partner, and her 50-year-old mother. INTERVENTION(S): In vitro fertilization with embryo cryopreservation before live donor uterus transplantation (UTx). Induction immunosuppression. Embryo transfer 12 months after UTx, pregnancy controls, delivery, and hysterectomy. MAIN OUTCOME MEASURE(S): Results of IVF-ET, parameters of pregnancy/birth, and surgical data of transplantation/cesarean section/hysterectomy. RESULT(S): Two IVF cycles before UTx resulted in 10 cryopreserved embryos. Donor surgery included hysterectomy with vascular pedicles of uterine vessels and proximal vessels up to and including parts of internal iliacs. Recipient surgery was by bilateral vascular connections to external iliacs, vaginal-vaginal anastomosis, and uterine fixation. Pregnancy occurred at the first single ET, and the pregnancy proceeded uneventfully until gestational week 34, when the patient developed cholestasis with intense pruritus. Cesarean section was performed at 34+6, with delivery of a healthy boy (weight 2,335 g). Hysterectomy was performed 3.5 months after delivery. The weight of the healthy child at 12 months was 9.3 kg. Grandmother (uterus donor) and mother are in good health 3 years after UTx. CONCLUSION(S): This is the first report of a live birth after mother-to-daughter UTx, and it also represents the second birth ever after human UTx. CLINICAL TRIAL REGISTRATION: NCT01844362.

Livebirth after uterus transplantation.

BACKGROUND: Uterus transplantation is the first available treatment for absolute uterine infertility, which is caused by absence of the uterus or the presence of a non-functional uterus. Eleven human uterus transplantation attempts have been done worldwide but no livebirth has yet been reported. METHODS: In 2013, a 35-year-old woman with congenital absence of the uterus (Rokitansky syndrome) underwent transplantation of the uterus in Sahlgrenska University Hospital, Gothenburg, Sweden. The uterus was donated from a living, 61-year-old, two-parous woman. In-vitro fertilisation treatment of the recipient and her partner had been done before transplantation, from which 11 embryos were cryopreserved. FINDINGS: The recipient and the donor had essentially uneventful postoperative recoveries. The recipient's first menstruation occurred 43 days after transplantation and she continued to menstruate at regular intervals of between 26 and 36 days (median 32 days). 1 year after transplantation, the recipient underwent her first single embryo transfer, which resulted in pregnancy. She was then given triple immunosuppression (tacrolimus, azathioprine, and corticosteroids), which was continued throughout pregnancy. She had three episodes of mild rejection, one of which occurred during pregnancy. These episodes were all reversed by corticosteroid treatment. Fetal growth parameters and blood flows of the uterine arteries and umbilical cord were normal throughout pregnancy. The patient was admitted with pre-eclampsia at 31 full weeks and 5 days, and 16 h later a caesarean section was done because of abnormal cardiotocography. A male baby with a normal birthweight for gestational age (1775 g) and with APGAR scores 9, 9, 10 was born. INTERPRETATION: We describe the first livebirth after uterus transplantation. This report is a proof-of-concept for uterus transplantation as a treatment for uterine factor infertility. Furthermore, the results show the feasibility of live uterus donation, even from a postmenopausal donor. FUNDING: Jane and Dan Olsson Foundation for Science.

Nitroglycerin for management of retained placenta: a multicenter study.

The primary aim was to determine if sequential administration of oxytocin and nitroglycerin is effective for management of retained placenta when performed by obstetricians with no experience of the method. Secondary aims were to examine possible adverse effects of nitroglycerin. One hundred and five women with retained placenta were randomly selected to receive either 1 mg nitroglycerin or placebo tablets sublingually if intravenous oxytocin had failed to expel the placenta. At two of the hospitals some of the midwives were familiar with the use of nitroglycerin. The other midwives and all the participating obstetricians had no clinical experience of the method. In the treatment group, detachment of placenta following nitroglycerin occurred in 37.3% of the women compared to 20.4% in the placebo group (P = 0.056). In the two hospitals with some experience of the method, placenta was removed in 9 of 19 (47.4%) women in the nitroglycerin group compared to 3 of 17 (15.0%) women in the placebo group. No adverse effects of clinical importance were registered. Although the difference between the two groups did not reach statistical significance, the higher success rate in the two hospitals with some experience could indicate that clinical experience is of importance in order to achieve placental detachment.

Microbial invasion and cytokine response in amniotic fluid in a Swedish population of women with preterm prelabor rupture of membranes.

BACKGROUND: Previous studies have shown an association between intra-amniotic microbial invasion and/or inflammation and spontaneous preterm birth. The aim of this study was to investigate the occurrence of intra-amniotic microorganisms and cytokines [interleukin (IL)-6 and IL-8] in a Swedish population, with low incidence of preterm birth, of women with preterm prelabor rupture of membranes and their correlation to preterm birth. METHODS: Amniotic fluid was retrieved transabdominally from 58 patients with preterm prelabor rupture of membranes before 34 weeks of gestation. Polymerase chain reaction (PCR) analyses for Ureaplasma urealyticum and Mycoplasma hominis and culture for aerobic and anaerobic bacteria were performed. IL-6 and IL-8 were analyzed with enzyme-linked immunosorbent assay (ELISA). RESULTS: Microorganisms in amniotic fluid were detected in 13 patients (25%). Patients with bacteria detected in the amniotic fluid had significantly higher levels of IL-6 and IL-8. An amniotic fluid concentration of IL-6 >/= 0.80 ng/ml [relative risk 1.93, 95% confidence interval (CI) 1.13-3.29, sensitivity 63%, specificity 75%] was associated with an increased risk of delivery within 7 days. There was also an association between IL-8 and preterm birth (< 34 weeks). CONCLUSIONS: Intra-amniotic microbial invasion and inflammation in this population of Swedish women with preterm prelabor rupture of membranes were similar to data reported from populations with a higher incidence of preterm delivery. Amniotic IL-6 correlated to the presence of microorganisms and delivery within 7 days and IL-8 to delivery before 34 weeks.

Microbial invasion and cytokine response in amniotic fluid in a Swedish population of women in preterm labor.

BACKGROUND: Previous studies indicate an association between intra-amniotic microbial invasion and/or inflammation and spontaneous preterm birth, but there is a limited amount of data available from Europe. The aim of this study was to investigate the occurrence of intra-amniotic microorganisms and cytokines (interleukin-6 and interleukin-8) in a Swedish population of women in preterm labor and their correlation with preterm birth. METHODS: Amniotic fluid was retrieved transabdominally from 61 patients in preterm labor before 34 weeks of gestation. Polymerase chain reaction analyses for Ureaplasma urealyticum and Mycoplasma hominis and culture for aerobic and anaerobic bacteria were performed. Interleukin-6 and interleukin-8 were analyzed with enzyme-linked immunosorbent assay. RESULTS: Microorganisms in amniotic fluid were detected in 10 patients (16%). Patients with detected bacteria in the amniotic fluid had significantly higher levels of interleukin-6 and interleukin-8. There was also an association between interleukin-6/-8, the amniocentesis-delivery interval (or= 1.5 ng/mL or interleukin-8 >or= 1.3 ng/mL was associated with an increased risk of delivery within 7 days (interleukin-6: relative risk 7.3; 95% confidence interval: 2.8-19; sensitivity 83%, specificity 87%; interleukin-8: relative risk 14, 95% confidence interval: 3.6-55, sensitivity 91%, specificity 87%). CONCLUSIONS: The occurrence of intra-amniotic microbial invasion and inflammation in this population of Swedish women in preterm labor was similar to data reported from populations with a higher incidence of preterm delivery. Amniotic interleukin-6 and interleukin-8 correlated with the presence of microorganisms and with preterm birth.
