Abstract Background Data on the prevalence of persistent symptoms in the first year after preeclampsia are limited. Furthermore, possible risk factors for these sequelae are poorly defined. We investigated kidney function, blood pressure, proteinuria and urine sediment in women with preeclampsia 6 months after delivery with secondary analysis for possible associated clinical characteristics. Methods From January 2007 to July 2014 all women with preeclampsia and 6-months follow up at the University Hospital Basel were analyzed. Preeclampsia was defined as new onset of hypertension (≥140/90 mmHg) and either proteinuria or signs of end-organ dysfunction. Hypertension was defined as a blood pressure ≥ 140/90 mmHg or the use of antihypertensive medication. Proteinuria was defined as a protein-to-creatinine ratio in a spot urine > 11 mg/mmol. Urine sediment was evaluated by a nephrologist. Secondary analyses were performed to investigate for possible parameters associated with persistent symptoms after preeclampsia. Results Two hundred two women were included into the analysis. At a mean time of follow up of 172 days (+/− 39.6) after delivery, mean blood pressure was 124/76 mmHg (+/− 14/11, range 116–182/63–110) and the mean serum-creatinine was 61.8 μmol/l (33–105 μmol/l) (normal 60 mml/min/1.73m2). 20.3% (41/202) had a blood pressure of 140/90 mmHg or higher (mean 143/89 mmHg) or were receiving antihypertensive medication (5.5%, 11/202). Proteinuria was present in 33.1% (66/199) (mean 27.5 mg/mmol). Proteinuria and hypertension was present in 8% (16/199). No active urine sediment (e.g. signs of glomerulonephritis) was observed. Age and gestational diabetes were associated with persistent proteinuria and severe preeclampsia with eGFR decline of ≥ 10 ml/min/1.73m2. Conclusion Hypertension and proteinuria are common after 6 months underlining the importance of close follow up to identify those women who need further care.
