Orthostatic proteinuria.

Adult orthostatic proteinuria

Orthostatic proteinuria is characterized by elevated levels of urinary protein excretion while in the upright or lordotic position and normal excretion when in the supine or recumbent position, such as that during bed rest. This type of proteinuria is the most frequent cause of isolated proteinuria in children and adolescents. In adolescents, the prevalence of orthostatic proteinuria is reporte...

Observations on aberrant renal arteries curving around and compressing the renal vein; possible relationship to orthostatic proteinuria and to orthostatic hypertension.

On Some Forms of Albuminuria Not Dangerous to Life

Dr. Grainger Stewart, in the January issue of The American Journal of the Medical Sciences, studies the following varieties: paroxysmal albuminuria; 2nd, dietetic albuminuria; 3rd, albuminuria from muscular exertion; and 4th, simple persistent albuminuria; and illustrates each with reports of cases which are markedly characteristic. The diagnostic features of paroxysmal albuminuria are the sudd...

Hereditary proteinuria syndromes and mechanisms of proteinuria.

N Engl J Med 2006;354:1387-401. Copyright © 2006 Massachusetts Medical Society. The inherited forms of proteinuria comprise a heterogeneous group of rare renal diseases in which glomerular dysfunction and proteinuria are prominent. Despite the rarity of hereditary proteinuria syndromes, genetic, biochemical, and structural studies of these diseases have made important contributions to our knowl...

Effects of Folic Acid Supplementation on Proteinuria in Type 2 Diabetic Patients with Overt Proteinuria

Objective: An association between high homocysteine levels and proteinuria in diabetic nephropathy has been shown. On the other hand, supplementation with folic acid lowers homocysteine concentration. We have studied the effects of folic acid supplementation on proteinuria in type 2 diabetic patients with overt proteinuria. Materials and Methods: Forty five (29 men and 16 women) type 2 diabe...
