To report the occurrence of Candida glabrata chorioamnionitis complicating an in vitro fertilization (IVF) pregnancy. Case report. University hospital. A 30-year-old woman, primagravida, with an IVF dichorionic-diamniotic pregnancy who presented at 15 weeks with vaginal bleeding. Before embryo transfer in next IVF cycle, vaginal culture from the patient revealed colonization with C. glabrata, which was treated with boric acid. Subsequent pregnancy after eradication of fungal organisms. The patient's first pregnancy was treated with indomethacin and broad-spectrum antibiotics, but her membranes ruptured, and she delivered both twins at 16 weeks; the autopsy and pathology reports were consistent with C. glabrata chorioamnionitis. After boric acid treatment eradicated the organisms, two embryos were transferred in subsequent IVF treatment; the second pregnancy was uncomplicated, with dichorionic-diamniotic twins, delivered by cesarean section at 38 weeks. Eradication of vaginal colonization with C. glabrata may prevent infection of the next IVF pregnancy.
