How Do Lupus Nephritis Patients Who Achieve Renal Remission Fare? A 3-year Comparison in Terms of GFR Decline
Background/Purpose: Lupus nephritis (LN) occurs in over 50% of SLE patients, contributing significant morbidity and mortality. Despite a generally accepted treatment goal of Complete Renal…Abstract Number: 1642 • ACR Convergence 2024
A Urinary Biomarker Panel to Predict the Probability of Histologically Active Lupus Nephritis
Background/Purpose: Achieving an NIH Activity Index of < 2 upon treatment is associated with less LN flare and thus better long-term kidney survival. Here, we…Abstract Number: 1686 • ACR Convergence 2024
Urine Proteomics in Class II Lupus Nephritis Reveals Immune Activation and Pro-Fibrotic Signatures
Background/Purpose: Lupus nephritis (LN) is a pathologically diverse autoimmune disease that can lead to end-stage kidney disease and mortality. Although Class II LN is considered…Abstract Number: 1798 • ACR Convergence 2024
CXCL6 Synthesized by Proximal Tubule Cells May Promote Fibrosis in Lupus Nephritis
Background/Purpose: Detection of urinary CXCL6, a member of the IL-8 chemokine family, has been linked to CKD and is a proposed marker of chronic damage…Abstract Number: 1802 • ACR Convergence 2024
Heterogeneous Neutrophil Subsets Infiltrate Glomeruli of Lupus Nephritis Patients and Are Elevated in the Kidneys and Urine of Sunlight-induced Nephritis Flares
Background/Purpose: Up to ~60% of SLE patients in North America will develop kidney disease, lupus nephritis (LN), one of the main contributors to disease morbidity…Abstract Number: 1811 • ACR Convergence 2024
The Immune Map of Lupus Nephritis: A Spatially Resolved Kidney Proteomic Approach
Background/Purpose: Treatment response rates in lupus nephritis (LN) remain suboptimal, highlighting the need for a better understanding of LN pathogenesis to enhance treatment strategies. Single-cell…Abstract Number: 2372 • ACR Convergence 2024
Incidence and Predictors of Recurrent Pericarditis in Systemic Lupus Erythematosus
Background/Purpose: Pericarditis is the most common cardiac manifestation of systemic lupus erythematosus (SLE). In the general population, pericarditis commonly recurs (~30%), likely due to immune-mediated…Abstract Number: 2413 • ACR Convergence 2024
The Natural History of SLE Has Changed Since the 1970s
Background/Purpose: We investigated the changes in the prevalence of specific SLE manifestations over the last 50 years. In addition, we looked for differences between African-Americans…Abstract Number: 1695 • ACR Convergence 2023
Single Cell Transcriptomics in Kidney Tissue from African American Patients Enrolled in the Accelerating Medicines Partnership (AMP) Implicates Tubular Cells in the Pathogenesis of APOL1 Associated Lupus Nephritis
Background/Purpose: The G1 and G2 risk variants (RVs) in Apolipoprotein L1 (APOL1) associate with CKD and may contribute to poorer outcomes for African American (AA)…Abstract Number: 2327 • ACR Convergence 2023
Hydroxychloroquine Improves Low Complement Levels
Background/Purpose: Low complement is associated with clinical disease activity and future organ damage in patients with systemic lupus erythematosus (SLE). Prior studies from Japan, although…Abstract Number: 2427 • ACR Convergence 2023
Degranulating PR3+ Myeloid Cells Characterize Proliferative Lupus Nephritis
Background/Purpose: As part of the Accelerating Medicines Partnership (AMP), we discovered that urinary PR3, a neutrophil degranulation product, is associated with histological activity, indicating the…
