Background: Contemporary data regarding pregnancy outcomes in US patients with primary glomerular diseases are lacking. We aimed to report fetal and maternal outcomes among women with biopsy-proven primary glomerular disease who received obstetric care at a single large academic US center. Methods: All women with a biopsy-confirmed primary glomerular disease diagnosis and without end-stage kidney disease who received obstetric care at the University of North Carolina (UNC) Hospitals (1996-2015) were identified using the Glomerular Disease Collaborative Network registry and the UNC Hospitals Perinatal Database. The primary study outcome was perinatal death (stillbirth at >20 weeks or neonatal death). Secondary outcomes included premature birth (<37 weeks), birth weight, preeclampsia, and kidney function changes (postpartum vs. baseline). Demographics, clinical characteristics, and outcomes were compared across glomerular disease subtypes. Results: Among 48 pregnancies in 43 women (IgA nephropathy n = 17, focal segmental glomerulosclerosis [FSGS] n = 16, membranous nephropathy n = 6, minimal change disease n = 4), 13% of pregnancies resulted in perinatal death and 48% of babies were born prematurely. From a maternal perspective, 33% of pregnancies were complicated by preeclampsia, 39% by a doubling of urinary protein, and 27% by a ≥50% increase in serum creatinine. Outcome differences across glomerular disease subtypes were not statistically significant, although decline in kidney function appeared most frequent in FSGS. Conclusion: Adverse pregnancy outcomes are frequently observed in women with glomerular disease. The independent influence of glomerular disease subtype on outcomes requires further study. More widespread reporting and analysis of pregnancy outcomes in women with glomerular disease are urgently needed.
