Measuring protein excretion in pregnancy.
The recognition and detection of proteinuria has been acknowledged as an important clinical marker of renal disease since 1827 when Richard Bright published his landmark medical case reports. In more recent times, the broader community of clinicians has come to share the enthusiasm of nephrologists in recognizing the importance of protein excretion, not only as a marker of current renal disease but also as a predictor of long-term renal and cardiovascular morbidity and mortality. It is important that methods for detecting and measuring proteinuria are accurate, and this is particularly relevant to diseases that are defined by the detection of proteinuria, such as pre-eclampsia. This review will first discuss current knowledge of protein handling by the normal kidney, then the changes in normal and hypertensive pregnancy, and finally, how recent advances in our understanding of proteinuria may affect our future management of hypertensive pregnancies.
