Proteinuria in sickle cell trait and disease: an electrophoretic analysis.
Using ultrafiltration and SDS-PAGE, abnormal urinary protein excretion was found in 25.4% of 189 persons with sickle cell disease and trait, but none of 72 controls. Based upon molecular weight of urinary proteins, underlying renal lesions were classified as glomerular, tubular, or both. Altered protein excretion appeared at an early age, was more abnormal in older subjects, and was related to the severity of sickle cell disease (SS greater than SC = S/beta Thal greater than AS). Since none of the subjects had yet developed clinically significant renal disease, SDS-PAGE may permit early detection of patients who require careful follow-up or aggressive therapy.
