ABSTRACT
RATIONALE & OBJECTIVE:
Preeclampsia is a pregnancy-related complication characterized by acute hypertension and end-organ dysfunction. We evaluated the long-term association between preeclampsia and the risk of developing chronic hypertension and kidney disease. STUDYDESIGN:
Observational cohort study. SETTING &PARTICIPANTS:
27,800 adults with deliveries in the Geisinger Health System between 1996 and 2019. EXPOSURE Preeclampsia.OUTCOME:
Hypertension, reduced estimated glomerular filtration rate (eGFR)<60mL/min/1.73m2), and albuminuria>300mg/g. ANALYTICALAPPROACH:
Propensity-score matching and Cox proportional hazards models to evaluate the association between preeclampsia and incident hypertension, reduced eGFR, and albuminuria.RESULTS:
Of 27,800 adults with pregnancies during the study period (mean age, 28 years; 3% Black race), 2,977 (10.7%) had at least 1 pregnancy complicated by preeclampsia. After matching for multiple characteristics, individuals with preeclampsia had a higher risk of developing chronic hypertension (HR, 1.77 [95% CI, 1.45-2.16]), eGFR<60mL/min/1.73m2 (HR, 3.23 [95% CI, 1.64-6.36]), albuminuria (HR, 3.60 [95% CI, 2.38-5.44]), and a subsequent episode of preeclampsia (HR, 24.76 [95% CI, 12.47-48.36]), compared with matched controls without preeclampsia. Overall, postpartum follow-up testing was low. In the first 6 months after delivery, 31% versus 14% of individuals with and without preeclampsia had serum creatinine tests, respectively, and testing for urine protein was the same in both groups, with only 26% having follow-up testing.LIMITATIONS:
Primarily White study population, observational study, reliance on ICD codes for medical diagnosis.CONCLUSIONS:
Individuals with a pregnancy complicated by preeclampsia had a higher risk of hypertension, reduced eGFR, and albuminuria compared with individuals without preeclampsia. PLAIN-LANGUAGESUMMARY:
Preeclampsia is a significant contributor to perinatal and maternal morbidity and is marked by new-onset hypertension and end-organ damage, including acute kidney injury or proteinuria. To gain insight into the long-term kidney effects of the disease, we compared adults with deliveries complicated by preeclampsia with those without preeclampsia in the Geisinger Health System, while also assessing postpartum testing rates. Our results demonstrate that pregnant individuals with preeclampsia are at a heightened risk for future hypertension, reduced eGFR, and albuminuria, with overall low rates of postpartum testing among both individuals with and without preeclampsia. These findings underscore the need to consider preeclampsia as an important risk factor for the development of chronic kidney disease. Further studies are required to determine optimal postpreeclampsia monitoring strategies.Palavras-chave
