Chronic Kidney Disease and Pregnancy

Women with chronic kidney disease (CKD) are at high risk for adverse outcomes in pregnancy. In the United States, pregnancy rates in women with risk factors for CKD such as obesity and advanced maternal age are increasing; thus, more pregnancies are likely to be affected by CKD. Strategies that involve coordinated multidisciplinary care to optimize preconception health, perform meticulous antenatal monitoring, and provide continued care in the postpartum "fourth trimester" appear to be most beneficial for both the mother and baby. Discussions surrounding preconception risk stratification should be individualized based on CKD stage/serum creatinine level, degree of hypertension and proteinuria, and comorbid conditions. Preparation for pregnancy should include optimization of comorbidities and medication adjustments to those compatible with pregnancy. Unless contraindicated, all women with CKD should be prescribed low-dose aspirin in pregnancy to reduce risk of preeclampsia. After delivery, women with CKD may benefit from an early postpartum visit (within 7-10 days) for blood pressure check and may require serial monitoring of serum creatinine and proteinuria as appropriate. Breastfeeding is safe and can be recommended for most women with CKD. A contraceptive plan that includes patients' preferences, feasibility, medical eligibility, duration, and effectiveness of the contraceptive method should be implemented.
