Extractions: The Cleveland Clinic Foundation National Guidelines National Kidney Foundation: Assessment of Proteinuria DEFINITION Proteinuria usually reflects an increase in glomerular permeability for normally non-filtered plasma macromolecules such as albumin. A 24-hour urine collection containing more than 150 mg of protein is abnormal. Significant proteinuria is suspected when a dipstick test of the urine is persistently positive for protein. In such a situation the daily protein excretion will usually exceed 300-500 mg per day. Since the dipstick method can detect urine protein concentration of as little as 30 mg/dL, a very concentrated urine specimen might test positive for protein even though the quantitative amount of proteinuria is less than 150 mg/day. of proteins in the urine. The SSA test is carried out by mixing 1 part urine supernatant (eg, 2.5 mL) with 3 parts 3% sulfosalicylic acid and grading the resultant turbidity

DISCUSSION BOARD PANEL DE DISCUSION. proteinuria AND RENAL DISEASE PROGRESSION. DGFR improved in parallel with a significant reduction on proteinuria.
http://www.uninet.edu/cin2000/conferences/remuzzi/remuzzi.html

Extractions: Introduction Progression to irreversible renal parenchymal damage and end-stage renal disease is the final common pathway of chronic proteinuric nephropathies and is relatively independent of the type of initial insult [1]. In animals, a reduction in nephron mass exposes the remaining nephrons to adaptive hemodynamic changes that are intended to sustain renal function but may be detrimental in the long term [2,3]. High glomerular capillary pressure impairs glomerular permeability to proteins, which are then filtered in excessive quantities and reach the lumen of the proximal tubule [4]. In the past the amount of proteins found in the urine, taken as an indicator of the underlying abnormality in glomerular permeability, was considered by most nephrologists simply as a marker of the severity of renal lesions. Today the results of many studies indicate that proteins filtered through the glomerular capillary may have intrinsic renal toxicity, which together with other independent risk factors such as hypertension, can play a contributory role in the progression of renal damage [1,5]. Indeed, the secondary process of reabsorption of filtered proteins can contribute substantially to renal interstitial injury by activating intracellular events, including up-regulation of vasoactive and inflammatory genes. The corresponding molecules formed in excessive amounts by the renal tubules cause an interstitial inflammatory reaction that normally precedes renal scarring and correlates with declining renal function [1] (Figure 1).

Extractions: Forma en que se realiza el examen: Existen dos m©todos para recolectar la orina para este examen. En el primero, la proteinuria puede detectarse en un "examen de mancha" por medio de una cinta de prueba (una tirilla especialmente tratada que se sumerge en una muestra de orina al azar) y en el segundo, se puede cuantificar en una muestra de 24 horas. El m©dico le solicitar¡ a la persona descontinuar medicamentos que pueden interferir con el examen si es necesario. Se necesita una muestra de orina de 24 horas recolectada de la siguiente manera: El da 1: la persona debe orinar en la taza del ba±o al levantarse en la ma±ana. Recolectar toda la orina subsiguiente (en un recipiente especial) durante las siguientes 24 horas. El da 2: la persona debe orinar en el recipiente al levantarse en la ma±ana. Tapar el recipiente y guardarlo en el refrigerador o en un lugar fresco durante el perodo de recolecci³n. Se debe marcar el recipiente con el nombre, fecha, hora de terminaci³n y retornarlo de acuerdo con las instrucciones.

Extractions: The health care provider will instruct you, if necessary, to discontinue drugs that may interfere with the test. The procedure for collecting urine over 24 hours is as follows: On day 1, urinate into the toilet upon arising in the morning. Collect all subsequent urine (in a special container) for the next 24 hours. On day 2, urinate into the container in the morning upon arising.

Proteinuria
proteinuria. proteinuria refers to the presence of protein in the urine. Theterm albuminuria may be used interchangeably with proteinuria.
http://www.rnceus.com/ua/uapro.html

Extractions: Proteinuria Proteinuria refers to the presence of protein in the urine. In healthy persons, the urine contains no protein or only a trace amount of protein. Proteins in the urine are comprised of albumin and globulin from the plasma. Because albumin is filtered more easily than globulin, it is the predominant type of protein that may appear in the urine. The term albuminuria may be used interchangeably with proteinuria. Detection of protein in the urine, combined with a microscopic exam of urinary sediment, provides the basis for the differential diagnosis of renal disease. Normally, the glomeruli prevent passage of protein from the blood to the glomerular filtrate. A small amount of filtered plasma proteins and proteins secreted by the nephrons can be found in normal urine; however, in healthy individuals, protein excretion does not exceed 150 mg in 24 hours or 10 mg per 100 ml of any single specimen. Glomerular injury causes increased permeability to plasma proteins, resulting in proteinuria. A persistent finding of proteinuria is the single most important indication of renal disease. If more than a trace of protein is found on a routine UA, a quantitative 24-hour evaluation of protein excretion is done. The dipstick method of checking for protein does not detect the presence of abnormal proteins such as globulins and Bence-Jones proteins excreted in multiple myeloma. Persons with diabetes have a higher than normal potential for renal disease, so they may have regular checks for proteinuria. If random samples are persistently positive for protein, a quantitative (24-hour) sample may be done.
APPROACH TO PROTEINURIA
APPROACH TO proteinuria MANAGEMENT. OF NEPHROTIC SYNDROME. proteinuria isusually due to renal disease with particular involvement of glomerulus.
http://www.imakerala.org/cme/proteinuria.htm

Extractions: Nehrologist, Medical College Hospital, Alappuzha Kidneys are a pair of retroperitoneal organs which perform very important functions to maintain the normal homeostasis. One such function is the fluid balance which is brought about by conservation of essential substances and excretion of certain others, of which proteins play an important role in maintaining plasma oncotic pressure. Reduction in plasma protein below a critical level due to its leak in kidneys leads to oedema formation which is the hallmark of nephrotic syndrome. Normal glomerular filtration is highly efficient producing @ 18OL of ultrafiltrate per day, which contains @ 11,000 to 14,000 gm of protein, yet the final urine is virtually protein free. This conservation of essential proteins is necessary for oncotic regulation as mentioned before. In addition, it is also important for the normal coagulation and immunological functions. Proteinuria is usually due to renal disease with particular involvement of glomerulus. It may be due to primary glomerulopathies or glomerulopathies secondary to systemtic diseases like DM, SLE, Amyloidosis, Lymphoma etc.

Thus, screening is not advocated except in those patients with IDDM. Over 3,000 patients are on ESRD programs (dialysis and transplantation) in Canada. An additional 2,000 patients enter dialysis programs every year, an annual increase of 7%.

Extractions: Questions Discussion After studying the pathologic findings of this case, further clinical information was obtained. The patient had a clinical diagnosis of systemic lupus erythematosus (SLE). Complement levels at the time of biopsy were: C330 mg/dl (nl:70-200mg/dl), and C4 <10 mg/dl (nl:15-50 mg/dl). The patient had high titers of antinuclear antibody with a speckled pattern. Systemic lupus erythematosus is a complex disease which involves multiple organ systems. It results from poor regulation of the immune response system with the production of numerous antibodies directed against plasma membrane components, plasma proteins, and cytoplasmic and nucleo proteins. As a consequence, immune complexes and subsequent inflammatory responses lead to pathologic tissue reactions in multiple organs. Intravascular thrombosis, associated with the presence of the lupus anticoagulant or anticardiolipin antibodies has also been implicated in the pathogenesis of this disorder. The multiple different morphologic patterns which occur in lupus nephritis is generally thought to be due to differences in immune response in various individuals, or in one individual over a course of time. There is evidence that various characterisitics of the antibodies such as idiotype also plays a role. Membranous glomerulonephritis, for example, develops after unstable immune complexes which dissociate in the peripheral circulation reform in the glomerular capillary wall. Positively charged histone proteins have been shown to have a high affinity to the glomerular capillary wall and may play a role in the development of the membranous version of lupus nephritis.
