Glomerular and tubular proteinuria as markers of nephropathy in rheumatoid arthritis

Abstract

Proteinuria is a frequent symptom of nephropathy in RA. Screening for renal disease in RA should not only include creatinine measurement and dipstick examination of urine, but also more sensitive methods to detect tubular and glomerular proteinuria as a marker of tubular and early stages of glomerular damage.
