title: Urinary tract infection during pregnancy affects the level of leptin, ghrelin and insulin in maternal and placental blood.
abstract: OBJECTIVE
  We examined ghrelin, leptin and insulin in maternal blood during normal pregnancy and pregnancy complicated by urinary tract infection (UTI), as well as in cord blood at labor.
  
  
  METHODS
  A total of 36 delivering women with history of UTI during the third trimester of pregnancy were enrolled in the study; 12 healthy pregnant women served as a control. Infection markers (CRP and procalcitonin) were determined in maternal blood during the course of UTI and at labor. Ghrelin, leptin and insulin were determined during labor in venous maternal and in umbilical cord blood.
  
  
  RESULTS
  We found negative correlation between infection markers in maternal blood during UTI, and level of tested hormones in cord blood, indicating potential risk of placental impairment due to energetic imbalance. We noted lower level of leptin in mothers with UTI and no change in leptin from umbilical blood comparing subjects with and without UTI. Low level of ghrelin was observed in maternal and cord blood when pregnancy was complicated by UTI. Insulin concentrations were high in mothers with UTI and low in their newborn's cord blood. Increased maternal insulin level could indicate peripheral insulin resistance caused by the infection.
  
  
  CONCLUSIONS
  UTI during pregnancy affects the concentration of hormones responsible for regulating energetic homeostasis within the placenta.
