title: Protein creatinine ratio in random urine sample of hypertensive pregnant women: maternal and perinatal outcomes.
abstract: Objective. To compare protein/creatinine ratio (PCR) in random urine sample levels and adverse outcomes in hypertensive pregnant women. Methods. A total of 370 medical charts from hypertensive pregnant women were reviewed and stratified into three groups according to different PCR in random urine sample levels (group 1: PCR < 0.3 mg/mg; group 2: PCR 0.3-1.99 mg/mg; group 3: PCR ≥ 2.0 mg/mg) and compared with composite maternal and perinatal outcomes. Those outcomes were severe hypertension, thrombocytopenia, high lactate dehydrogenase count, disseminated intravascular coagulation, abruptio placentae, HELLP (hemolysis, elevated liver enzymes, low platelet count) syndrome, eclampsia, perinatal death, newborn cerebral hemorrhage, respiratory distress syndrome of newborn, neonatal sepsis, and newborn small for gestational age. Results. To obtain a composite maternal adverse outcome the odds ratio [ORs] between PCR groups were 1.8 (95% confidence interval [CI]: 1.1-3.2) between groups 1 and 2, and 3.1 (95% CI: 1.5-6.3) between groups 1 and 3; for composite perinatal adverse outcomes, the ORs were 3.0 (95% CI: 1.5-5.9) between groups 1 and 2, and 3.4 (95% CI: 1.6-7.5) between groups 1 and 3. Conclusions. Hypertensive pregnant women with a PCR ≥ 0.3 mg/mg, had worse maternal and perinatal outcomes than those with PCR < 0.3 mg/mg. Above the cut-off of 0.3 mg/mg, higher PCRs are not associated with a significant increase in maternal and perinatal morbidity.
