[Ovum collection following ovarian stimulation in patients with chronic active Epstein-Barr virus infection]

The only curative treatment for chronic active Epstein-Barr virus infection (CAEBV) is hematopoietic stem cell transplantation. For young female patients, ovulation induction and oocyte cryopreservation may be performed prior to transplantation to provide for future pregnancies. However, the effects of this ovum treatment on CAEBV and EBV infections have not been reported. Attempts were made to collect ova from three female CAEBV patients before transplantation conditioning, but this was only successful in two cases. Ovarian stimulation did not induce disease progression, and there was no change in the peripheral blood EBV DNA load. In one patient, 460 copies/ml of EBV DNA were detected in the follicular fluid by real-time PCR. Red blood cells were also present in the follicular fluid but not mononuclear cells. EBV protein mRNA was not detected in the RNA extracted from the same fluid, suggesting that the EBV DNA resulted from peripheral blood contamination. Moreover, there were no EBV-infected cells in the follicular fluid. Therefore cryopreservation of oocytes from CAEBV patients is possible and may be used to provide for future pregnancies.
