Mûllerian anomalies are associated with infertility and obstetric complications, such as recurrent pregnancy loss, preterm labor or birth, as well as malpresentation. The most common anomalies inlude septate uterus, uterus bicornuate, and uterus didelphys (Class II and III according to ESHRE/ESGE classification). Hypoplastic uteri are rare, being usually caused by in utero exposure to diethylstilbestrol. Hysteroscopic metroplasty has been shown to improve both fertility and obstetrical outcomes in patients with hypoplastic or septate uterus [less ▲]

A few years ago, the prevention of anti-D immunization was currently based on systematic postnatal prophylaxis associated with targeted antenatal injection in high-risk situations of foeto-maternal haemorrhage. The failures of prevention are mainly due to the non-respect of established guidelines for RhIG prophylaxis, and to spontaneous undetected foetal-maternal haemorrhages without any obvious cause during the third trimester of pregnancy. In order to reduce the rate of residual post-pregnancy anti-D immunization, several countries decided to associate the classical prophylaxis to a routine antenatal anti-D prophylaxis (RAADP) during the 28th or 29th week of gestation. Since about ten years, the foetal RHD genotyping in maternal plasma enables us to limit the antenatal prophylaxis only to those D- women carrying a D+ foetus. This paper deals with: the advantages of an antenatal prevention in the light of non invasive foetal RHD genotyping, the rules rendering prevention protocols efficient whatever the algorithm applied, and the recommended immuno-haematology follow-up of women who have received RhIG.

Study question: In a model reproducing early ischemia after ovarian tissue transplantation, does the pan-caspase inhibitor Z-VAD-FMK could prevent granulosa cell apoptosis? Summary answer: Results obtained with HGL5 granulosa cell line suggest that Z-VAD-FMK is efficient to protect granulosa cells from etoposide or CoCl2 induced apoptosis. What is known already: Removal, cryopreservation and subsequent graft of ovarian strips after cancer treatment have been successfully used to re-establish female fertility. However, the pregnancy rate after autografting of cryopreserved tissue is about 30%. Indeed, the major problem after transplantation is follicular loss due to ischemic reperfusion injury. Study design, size, duration: Three human granulosa cell lines (GC1a, HGL5 and COV434) were cultured during 48h with Z-VAD-FMK with or without etoposide to induce apoptosis. To reproduce the ischemic phase of the graft, cells were cultured without serum under reduced O2 (1%) or with CoCl2 (chemical hypoxia). Participants/materials, setting, methods: Granulosa cells were used as a model since they are essential for oocyte survival. Metabolic cell activity was evaluated by the WST-1 assay. Cell apoptosis was analyzed by flow cytometry after annexin V-FITC and propidium iodide double staining. The mRNA levels and protein expression of apoptotic markers were evaluated using RT-qPCR and western blot analysis. Main results and the role of chance: Flow cytometry showed that cells co-treated with etoposide and Z-VAD-FMK displayed a higher percentage of viable cells as compared to etoposide alone. When in vivo ischemic stage was mimicked (1% O2), no beneficial effect of the Z-VAD-FMK was detected. However, a significant decrease of the number of early apoptotic cells was evidenced by flow cytometry for HGL5 cells treated with Z-VAD-FMK. RT-qPCR and western blot analysis revealed that apoptotic molecules were not modulated. Metabolic activity of the 3 cell lines was reduced by CoCl2. For HGL5 cells, this decrease was partially reversed by Z-VAD-FMK. The number of viable cells was reduced by CoCl2 in HGL5 cells but Z-VAD-FMK allowed to preserve a similar number of viable and apoptotic cells than in control condition. Limitations, reasons for caution: In this study we used 3 different cell lines but granulosa cells represent only a part of the cell types present in ovarian tissue biopsies. Experiences on the effect of Z-VAD-FMK on primary culture of granulosa cells have not yet been realized. Wider implications of the findings: This study suggests that the use of an antiapoptotic drug could be efficient to improve ovarian tissue transplantation outcomes. Ovarian tissue grafting studies using our xenograft murine model will be performed to test the potential efficacy of this drug to improve tissue viability and primordial follicles preservation after transplantation.
