ABSTRACT
BACKGROUND: To establish correlations between laboratory findings and clinical symptoms of moderate and severe ovarian hyperstimulation syndrome (OHSS). DESIGN: A retrospective study. SETTING: Department of obstetrics and gynecology, public clinical hospital. PATIENTS: Nineteen women admitted to the public hospital with a diagnosis of OHSS. The procedure of controlled ovarian stimulation (COH) was performed in the private assisted reproductive technology centre. METHODS: Blood samples were collected, ultrasound examination of ovaries, abdominal circumference measurement were performed, intravenous crystalloids, plasma expanders such colloids and albumin were given. Correlations between mean laboratory results (haematocrit, c-reactive protein (CRP), white blood count, serum protein, serum albumin), ovarian size in ultrasound examination, abdominal circumference, and amount of albumin and hydroxyethyl starch transfused to the patient were assessed. RESULTS: Significant correlation was observed between CRP concentration and abdominal circumference measured when the patient was admitted to the department, between CRP concentration and ovarian size measured during ultrasound examination at admission and between CRP concentration and body weight. CONCLUSIONS: CRP can be a potential candidate to an indicator of OHSS severity.
