Revaluation and lessons learned from the first 9 cases of a Czech uterus transplantation trial: Four deceased donor and 5 living donor uterus transplantations
Uterus transplantation is the surgical treatment for absolute uterine factor infertility (AUFI), a congenital or acquired condition characterized by the absence of a uterus. More than 80 transplants have been performed worldwide, resulting in more than 30 live births, originating both from living and deceased donors. The collection of published articles on deceased donor uterus transplantations was performed in PubMed and SCOPUS by searching for the terms "Uterus transplantation" AND "deceased donor"; from the 107 articles obtained, only case reports and systematic reviews of deceased donor uterus transplantations and the resulting live births were considered for the present manuscript. The extracted data included the date of surgery (year), country, recipient (age and cause of AUFI) and donor (age and parity) details, outcome of recipient surgery (hysterectomy), and live births (date and gestational age). The search of peer-reviewed publications showed 24 deceased donor uterus transplantations and 12 live births (a birth rate of 66%) with a 25% occurrence of graft loss during follow-up (6 of 24). Among this series, twelve transplants were performed in the USA (seven births), five in the Czech Republic (one birth), three in Italy (one birth), two in Turkey (two births), and two in Brazil (one birth). The median recipient age was 29.8 years (range 21-36), while the median donor age was 36.1 years (range 20-57). Of 24 recipients, 100% were affected by MRKH (Mayer-Rokitanski-Kuster-Hauser) syndrome. Two live births were reported from nulliparous donors. Deceased donor uterus transplantation birth rates are very similar to the living donor rates reported in the literature, but ethical implications could be less important in the first group. It is necessary to register every case in the International Registry for Uterus Transplantation in order to perform a systematic review and comparison with living donor rates.

INTRODUCTION: Uterus transplantation is a causal treatment for absolute uterine factor infertility. Assessing rejection signs using a histopathological examination of the ectocervical biopsy from the transplanted uterus is common practice in all human uterus transplants worldwide to date. A provisional scoring system was used for the histopathological assessment of subclinical rejection signs in uterus recipients. Here we hypothesized that histopathological and immunohistochemical findings in the normal uteri would differ from the borderline category of subclinical rejection in uterine transplants. MATERIAL AND METHODS: This prospective observational study included ectocervical biopsies of 54 women who underwent hysterectomy for benign reasons. All biopsy samples were assessed histopathologically and immunohistochemically. RESULTS: Most of the ectocervical biopsies showed clustering lymphocytic infiltrates affecting the stromal-epithelial interface with the epithelial influx of lymphocytes, primarily CD45RO-positive activated T-cells with CD8 T-lymphocyte predominance. CD4-positive T-lymphocytes and B-cells were rarely detected in the ectocervix. These morphological findings and immunoprofiles of lymphocytic populations overlapped with the so-called borderline changes defined in the provisional scoring system for rejection in the transplanted uteri. The immunoprofiles of ectocervical and endocervical lymphocytic populations differed, with strikingly prominent B-cell participation in the endocervix vs the rare detection of B-cells in the ectocervix. CONCLUSIONS: The histopathological and immunohistochemical findings in the uteri of premenopausal women were similar to the borderline category of the currently used provisional scoring system of subclinical uterine rejection utilized in all uterine transplant studies. However, future similar studies are required to validate our findings.

INTRODUCTION: Uterus transplantation (UTx) is a rapidly evolving treatment of uterine-factor infertility. We report the results of the first 10 UTx procedures performed at our institution. METHODS: The program started in April 2016 as a two-arm study comparing the efficacy of UTx from live donors (LD) and deceased donors (DD). RESULTS: Between April 2016 and April 2018, we performed five DD UTx and five LD UTx. Two grafts had to be removed early due to thrombosis. One graft was removed due to chronic rejection and previous herpes simplex infection at month 7. Graft survival is 70% at one year. Recipient survival is 100% at two years. Live donor survival is 100% at three years. Three live-births have been achieved, two from a LD and one from a graft from a nulliparous DD. Vaginal anastomotic stenosis occurred in 63% (5/8) of grafts. Self-expanding stents have shown preliminary suitability for the treatment of vaginal stenosis. Three recipients developed severe acute rejection. CONCLUSION: The interim results of our study demonstrate mid-term viability in 70% of grafts. The LD UTx produced two live births and the DD UTx produced one live birth. Nulliparous donors should be considered for donation.
