RESUMO
Posterior reversible encephalopathy syndrome (PRES) is a cliniconeuroradiological entity presenting with headache, confusion, visual disturbances or blindness, and seizures. Parieto-occipital white matter changes due to vasogenic oedema can be observed on imaging modalities. It rarely occurs without seizures and after delivery. We report a 33-year-old multigravida with a history of preeclampsia in term pregnancy complicated by PRES without seizures at the postpartum period. Clinical improvement with complete resolution without any complications was observed on the 6th day after delivery. Posterior reversible encephalopathy syndrome is reversible when early diagnosis is established and appropriate treatment is started without delay.
RESUMO
OBJECTIVE: The aim of this study was to determine the plasma levels of natriuretic peptides amino-terminal pro B-type natriuretic peptide (NT proBNP) and amino-terminal pro C-type natriuretic peptide (NT proCNP) during pregnancy and any possible changes occurring in each trimester. METHODS: This was a prospective longitudinal case-control study conducted in a University Hospital antenatal outpatient clinic. Subjects were all healthy pregnant women without a history of previous cardiac disease, hypertension or preeclampsia, and each patient was assessed during every trimester, and blood samples were collected for the measurement of NT proBNP and NT proCNP levels. RESULTS: Twenty pregnant women were followed-up during pregnancy without any complications. We obtained longitudinal levels of natriuretic peptides in each trimester. The mean NT proBNP levels were 14.95 ± 16.8, 9.37 ± 10.76, 52.48 ± 126.65 pmol/ml and the mean NT proCNP levels were 44.64 ± 41.64, 45.70 ± 47.03, 47.22 ± 55.09 pmol/l, respectively. No statistically significant alteration of plasma levels of natriuretic peptides was detected between trimesters. CONCLUSION: This is the first study evaluating the longitudinal levels of NT proCNP during the pregnancy, and demonstrates that NT proCNP remained constant, but NT proBNP levels do not significantly alter during pregnancy.
