title: [Risk factors analysis of reversible posterior leukoencephalopathy syndrome in pre-eclampsia or eclampsia gravida].
abstract: Objective:To investigate the risk factors of reversible posterior leukoencephalopathy syndrome (RPLS) in pre-eclampsia or eclampsia gravida.Methods:This study was conducted in the Third Affiliated Hospital of Guangzhou Medical University between January 2013 and March 2016. A total of 100 patients who had no severe neurological diseases and were diagnosed pre-eclampsia or eclampsia, and underwent brain MRI were collected retrospectively. They were divided into 2 groups according to the MRI results, the RPLS group (n=49) and the non-RPLS group (n=51). The medical history, clinical symptoms and the results of laboratory examination were analyzed by the logistic regression, in order to explore the risk factors.Results:In single factor analysis, HELLP syndrome, pregnancy associated with other diseases, poor prenatal care, grade 3 hypertension, elevated systolic blood pressure or diastolic blood pressure, elevated WBC, aspartate transaminase (AST), alanine aminotransferase (ALT), uric acid (UA) and lactate dehydrogenase (LDH), decreased platelet (PLT), headache, visual changes, seizures and conscious disturbance were more frequent in the RPLS group than those in the non-RPLS group (allP<0.05). According to the multivariate logistic regression analysis, the elevated WBC (OR=1.291, 95%CI: 1.058-1.575,P=0.012), UA (OR=1.008, 95%CI: 1.001-1.016,P=0.032) and headache (OR=18.260, 95%CI: 3.562-93.607,P=0.000) were the independent risk factors.Conclusions:Maternal history, clinical symptoms and some laboratory examinations might help in the early diagnosis of RPLS in pre-eclampsia or eclampsia gravida. Headache, the elevation of WBC and UA were the most significant factors.
