Severe ovarian hyperstimulation syndrome after combined GnRH-agonist and low-dose human chorionic gonadotropin trigger in a patient with a single kidney.
Overview
abstract
Ovarian hyperstimulation syndrome (OHSS) following gonadotropin-releasing hormone agonist (GnRH-a) trigger is rare. Here, we report a case of severe OHSS after combined GnRH-a and low-dose human chorionic gonadotropin (hCG) trigger in a patient with a single kidney. The patient is a 32-year-old women with a two-year history of infertility. The patient's history was significant for a single kidney, that is, she had donated a kidney to a family member three years ago. The patient underwent controlled ovarian stimulation (COS) for in vitro fertilization (IVF) and received a combined 2 mg GnRH-a and 1500 IU hCG ovulatory trigger. Estradiol (E2) levels on the day of and after the trigger were 3800 pg/mL and 4001 pg/mL, respectively. Four days after the trigger, the patient began experiencing nausea, abdominal distention and dyspnea, and her blood testing revealed hemoconcentration (hemoglobin: 16.9 g/dL; hematocrit: 51.0%) and an elevated creatinine level (1.16 mg/dL). Fresh embryo transfer was deferred. The patient was admitted to the hospital for fluid monitoring and prophylactic anticoagulation. Following inpatient management, her hemoglobin, hematocrit and creatinine levels normalized. The current report highlights that the systemic effects of OHSS can be accentuated in patients with preexisting renal disease or a single kidney.
