ABSTRACT

OBJECTIVE: To assess the predictive abilities of serum and urinary cystatin C levels for glomerular lesions in pregnant women with pre-eclampsia. METHODS: In this study, kidney function markers were compared between38 pregnant women with pre-eclampsia and 22 healthy pregnant women. RESULTS: The serum and urine levels of cystatin C and urea were significantly higher in the pre-eclampsia group than in the control group. Receiver operating characteristic curve analysis demonstrated that the serum cystatin C level (91.7%) had a superior diagnostic accuracy for pre-eclampsia than the other markers. CONCLUSION: Serum cystatin C level maybe a significant marker of pre-eclampsia.

ABSTRACT

A função renal alterada é um componente essencial do processo fisiopatológico que está relacionado ao pior prognóstico materno-fetal. Os rins estão entre os órgãos centrais afetados na pré-eclâmpsia, e desempenham um papel significativo na síntese e degradação das substâncias de baixo peso molecular, como creatinina, ureia e cistatina C. A cistatina C vem sendo apontada como uma substância promissora para avaliar a função renal, e alterações da filtração glomerular precocemente. O presente trabalho foi realizado para investigar a cistatina C sérica e urinária como marcador de lesão glomerular em grávidas portadoras de PE, e correlacionar com a dosagem de creatinina e uréia. Trata-se de um estudo transversal com 44 gestantes com diagnóstico da pré-eclâmpsia e 24 normotensas. Os níveis de cistatina C plasmáticos e urinárias apresentam-se elevados e estatisticamente significativos (respectivamente, p=0,001, p=0,012) nas mulheres portadoras de PE quando comparadas com as normotensas. Comparando-se com outros marcadores, a cistatina C sérica demonstrou melhor capacidade de identificar a função renal, com valor percentual de área da curva ROC de 91,7%. Nesse estudo, a cistatina C mostra-se um bom marcador de lesão glomerular em gestantes portadoras de pré eclâmpsia, comparável aos marcadores tradicionais uréia e creatinina. Sua vantagem sobre estes marcadores refere-se a sua menor influência de diversos aspectos biológicos não relacionados a doença gestacional propriamente dita.


Renal function is an essential component of the pathophysiological process that is related to the worst maternal-fetal prognosis. The kidneys are among the major levels of affection in PE, and play a significant role in the turnover of most low molecular weight substances such as creatinine, urea and cystatin C. Cystatin C has been shown to be a promising substance for assessing renal function and glomerular filtration changes earlier. The present study was carried out to investigate serum and urinary cystatin C as marker of glomerular lesion in pregnant women with PE, and correlate with creatinine and urea. It is a cross-sectional study with 44 pregnant women diagnosed with preeclampsia and 24 normotensive women. Plasma and urinary cystatin C levels were elevated and statistically significant (p = 0.001, p = 0.012) in women with PE compared to normotensive women, respectively. Compared with other markers, serum cystatin C demonstrated a better ability to identify renal function, with a percentage of area of the ROC curve of 91.7%. Cystatin C is a good marker of glomerular lesion in pregnant women with preeclampsia, comparable to traditional urea and creatinine markers. Their advantage over these markers is their lower influence of several biological aspects unrelated to gestational disease itself.
