The comparison between the serum level of interleukin-6 in women with acute ovarian torsion and other causes of lower abdominal pain.

The aim of this study was to investigate the role of serum Interleukin-6 (IL-6) as a predictive value to make decision for surgical interventions when ovarian torsion (OT) is suspected. This study was performed on 284 women with lower abdominal pain. IL-6 levels were compared between OT (n = 67, 23.6%) and control groups (n = 217, 76.4%). For the purpose of diagnosis of OT, sensitivity and specificity of IL-6 at the cut-off point of 9.6 pg/ml were 41.79 and 82.49%, respectively. Patients with ovarian masses on ultrasound and IL-6 >9.6 pg/ml were found to be 24 times more likely to develop OT. Patients with serum IL-6 >9.6 pg/ml who lacked blood flow in ovarian Doppler ultrasound had 40.75 times higher risk of developing OT. It seems that simultaneous use of Doppler ultrasound and serum IL-6 levels can be helpful for early diagnosis of OT and making decision for surgical intervention.
