title: Oxidative status shifts in uterine cervical incompetence patients.
abstract: Uterine cervical incompetence (UCI) is a pregnancy complication affecting about 10% of the pregnancies in the western world. Studying the etiology of the UCI requires a specific approach adequate for this highly heterogenous syndrome. Oxidative status disorders are associated with various pathologies, including pregnancy complications. As such, general oxidative status profiling is a promising methodology to treat UCI. We aimed at assaying the closely interrelated oxidative status markers in the uterine cervical incompetence patients by means of the systems biology-oriented approach. Chemiluminescent assay, circulating thioredoxin 1 protein, uric acid, and homocysteine level measurements were used to assess the character of the oxidative status regulation in the UCI patients. We found UCI to be associated with the atypical plasma oxidative status deregulation; UCI plasma samples demonstrated lowered proneness to the pro-oxidative processes, and this was not due to the excessive antioxidant activity. There were neither signs of oxidative stress nor destructive pro-oxidant feedforward circuit locking in the UCI group. We also report increased circulating levels of uric acid in the UCI patients.
