Cellular expression of CD80 and CD163 may play a role in the pathogenesis of certain glomerulopathies. Urinary or blood concentrations may predict and/or track response to specific immunosuppressive therapies and long term renal function.


Urine was obtained from Mayo Clinic patients (286) and NEPTUNE cohort participants (104) with biopsy-proven minimal change disease (MCD, 103), focal segmental glomerulosclerosis (FSGS, 97), lupus nephritis (LN, 31), IgA nephropathy (IgAN, 28), and membranous nephropathy (MN, 54), as well as non glomerular disease patients with autosomal dominant polycystic kidney disease (ADPKD, 9), pyuria (19), and controls (34). Data expressed as (mean, median (IQR)) was analyzed by Kruskal-Wallis test, generalized estimating equation models (GEE) or receiver operating characteristic (AUC) curve analysis.


CD80/Creatinine and CD163/Creatinine were higher in relapse vs remission in paired urine samples of MCD and FSGS cases (GEE: Active vs. remission p<0.0001); MCD vs. FSGS p<0.0001). Urinary CD80/Creatinine ratios were higher in active MCD, LN, DN and CD163/Creatinine was higher in active LN compared to active cases of other glomerular diseases or controls (Table 1). Differences remained significant after adjusting for proteinuria (p≤0.01; GEE).


Urinary CD80 and CD163 excretions varied between disease groups and by disease activity. These results suggest a pathogenic role for these molecules in certain glomerular diseases, including diabetic nephropathy.

Urinary CD80/creat and CD163/Creat discriminate by proteinuric kidney disease type.
