increased excretion of normally filtered low-molecular weight proteins due to impaired reabsorption by the proximal tubules. A UPr/Cr greater than.0 is associated with nephrotic syndrome, and further evaluation with history, physical examination, and additional blood work is essential. Original Article 47 Downloads 18 Citations, abstract, in a mass screening programme, 54 children with haematuria and proteinuria were detected and evaluated by clinical findings and renal histology. Proteinuria can cause damage in the epitheliumof glomeruli leading to the loss of podocyte and production of chemokines and cytokines that can cause inflammatory response. Casts and proteinuria may be present because the person is recovering from a recent undiagnosed episode of kidney inflammation (nephritis). Yoshikawa N, Ito H, Yoshiya K, Nakahara C, Yoshiara S, Hasegawa O, Matsuyama S, Matsuo T (1987) Henoch-Schoenlein nephritis and IgA nephropathy in children: a comparison of clinical course. Clinical features from the history, physical examination, and laboratory tests help determine the cause of proteinuria. An elevation in blood urea nitrogen or serum creatinine suggests impaired renal function. Gordillo R, Spitzer.

Patients with post-infectious glomerulonephritis usually have a history of pharyngitis or impetigo before 2-4 weeks and present with an acute nephritic syndrome, hematuria, proteinuria, hypertension, and acute renal failure. If red blood cells (particularly casts) and proteinuria persist, the cause is usually one of three disorders: Immunoglobulin A (IgA) nephropathy, a type of glomerulonephritis caused by deposition of immune complexes (combinations of antibodies and antigens) in the kidneys that can be very mild and. Heavy proteinuria is marked when wasting of protein is more than 2-3 g per day with a ratio of protein and creatinine 200-300. 1, 9, 10 The electrostatic barrier consists of negatively charged sialoproteins and proteoglycans. If the UPr/Cr is greater than.2 (greater than.5 for children six to 24 months of age or if urinalysis results are abnormal (e.g., hematuria, leukocyturia, active urinary sediments persistent proteinuria or proteinuria of clinical significance is more likely.
