title: Clinical, but Not Laboratory Features Are Predictive of Risk of Subsequent Development of Preeclampsia in Patients With Isolated Proteinuria After Midgestation.
abstract: OBJECTIVE
  The present study aimed to investigate perinatal outcomes and to describe antenatal factors for development of preeclampsia (PE) in patients with isolated proteinuria in pregnancy.
  
  
  METHODS
  This retrospective case control study consisted of patients with isolated proteinuria between 2009 and 2014. The patients were considered as gestational proteinuria (GP) (group 1, n: 35) if they remain normotensive. Patients who develop PE after onset of proteinuria were allocated into group 2 (n: 19). Perinatal outcomes of patients in each group were compared. Logistic regression analysis was performed to detect antenatal risk factors for PE.
  
  
  RESULTS
  The rate of small for gestational age (SGA) fetuses was higher in patients with isolated proteinuria than control group. In the logistic regression model, maternal age and completed gestational weeks at onset of proteinuria decreased the risk of PE in multivariate analysis (OR: 0.849 (95% CI: 0.731-0.986), OR: 0.732 (95% CI: 0.594-0.902) respectively). Systolic BP at onset of proteinuria, however, was associated with an independently increased risk of PE (OR: 1.181 (95% CI: 1.046-1.333)).
  
  
  CONCLUSIONS
  Maternal clinical characteristics, but not laboratory features may help to predict development of PE.
