Abstract

RATIONALE & OBJECTIVE: Cardiovascular (CV) and thromboembolic (TE) events are known complications of glomerular disease (GD), but their incidence and risk factors are poorly characterized. This analysis describes CV and TE outcomes in the Cure GlomeruloNephropathy (CureGN) Network.

STUDY DESIGN: Prospective cohort study.

SETTING & PARTICIPANTS: CureGN is a prospective cohort study of children and adults with biopsy-proven minimal change disease (MCD), focal segmental glomerulosclerosis (FSGS), membranous nephropathy (MN), or IgA nephropathy (IgAN)/vasculitis (IgAV). Data from 2,545 children and adults (23% MCD, 23% MN, 25% FSGS, 29% IgAN/IgAV) was analyzed.

EXPOSURE: Estimated glomerular filtration rate (eGFR), proteinuria, serum albumin, tobacco use, body mass index, hypertension, renin-angiotensin-aldosterone system.

OUTCOMES: CV and TE events.

ANALYTIC APPROACH: Kaplan-Meier curves were used to estimate cumulative incidence, and multivariable Cox proportional hazards models were fitted to estimate associations of histologic diagnosis, age, biological sex, and race. Laboratory and other clinical data were evaluated separately in models adjusted for base model covariates.

RESULTS: Median follow-up time was 4.6 years (IQR 2.7-6.1). The cumulative incidence of first CV and TE event postbiopsy was 3% and 2% in children and 10% and 5% in adults, respectively. No association between GD subtype and risk of CV or TE event was detected. Older age and Black race were associated with higher risk of first CV and TE event {hazard ratio (HR) (95% confidence interval {CI}) per 5 years, CV = 1.17 (1.12-1.23); TE = 1.11 (1.05-1.18); for Black race, CV = 1.62 (1.03-2.56), TE = 2.25 (1.27-4.01)}. Lower eGFR, higher urinary protein-creatinine ratio (UPCR), and lower serum albumin levels at enrollment were associated with higher risk of first CV and TE event (eGFR per 10 mL/min/1.73 m

LIMITATIONS: Age of cohort, duration of follow-up.

CONCLUSIONS: In the CureGN cohort, elevated risk of incident CV and TE events is associated with severity of kidney disease rather than GD subtype.
