Longitudinal follow-up of kidney function in patients with a history of preeclampsia: From 11 to 18 years postpartum.

Formerly preeclamptic (fPE) women are reported to have an increased risk to develop end stage kidney disease. To gain more insight in the course of kidney function after preeclampsia we assessed blood pressure, eGFR and urinary protein loss in 75 fPE women at 11 and 18 years postpartum. We found that during follow-up blood pressure did not increase and no cases of CKD were identified. Only a small decrease in eGFR (6-7 mL/min) and a small increase in urinary protein loss were observed, which fall within the expected range of normal aging. In conclusion, our data suggests that progression to kidney disease might not be a major concern in women after preeclampsia within 18 years postpartum.
