PIDL Home/ Contents Development Nutrition Acute Illness ... Psychosocial Nephrology EVALUATION OF ASYMPTOMATIC PROTEINURIA Despite the availability of sophisticated methods for the determination of protein in the urine, the evaluation of the child with proteinuria represents a difficult problem. Proteinuria may be completely benign or may herald the presence of significant renal parenchymal disease and chronic renal failure. Normal protein excretion is affected by the interplay of glomerular and tubular mechanisms. Damage to either the glomerulus or the proximal tubular cells results in an increased loss of protein. Glomerular injury results in abnormal losses of intermediate molecular weight proteins such as albumin as well as some larger macromolecules, and is by far the most common. Tubular damage, yields increased excretion of low molecular weight proteins. Table 1 gives a listing of normal daily urinary protein excretion as a function of age. There are two semiquantitative tests for proteinuria. The most common is the dipstick method. Urinary protein induces color changes of the indicator dye, tetrabromphenol, which is buffered to maintain the pH of the paper at 3.0. The test in unaffected by x- ray contrast material and drugs. False positives occur with strongly alkaline urine. In patients with nonalbumin proteinuria, the dipstick may demonstrate no color change. To circumvent missing mild proteinuria, it is recommended that only concentrated urines be tested. The second method is a turbidimetric test using sulfosalicylic acid. False positive reactions may occur with x- ray contrasts media, penicillin, and sulfisoxazole metabolites.

Proteinuria: Causes Glomerular permeability is affected by molecular weight, size, shape and electrical charge of molecules. It is also influenced by renal hemodynamics. In general, the renal threshold is 68,000 daltons, therefore the glomerular filtrate contains electrolytes (in a similar concentration to plasma) and low molecular weight proteins. These filtered proteins are normally taken up and catabolized by renal tubular epithelial cells, therefore altered renal tubular function can result in these proteins being retained in the urine (tubular proteinuria). Alterations in the glomerular barrier from altered renal blood flow (e.g. passive venous congestion in congestive heart failure) may result in mild proteinuria, whereas glomerular disease will result in a significant and severe proteinuria, consisting mostly of albumin (glomerular proteinuria). Increased filtration of low molecular weight proteins that are in high concentration in blood (hemoglobin, myoglobin, Bence-Jones proteins) will result in a significant proteinuria as the high concentration of these proteins in the filtrate overwhelm the renal tubular resorptive capacity (prerenal proteinuria). Urinary tract inflammation and hemorrhage will also result in proteinuria because of the contribution of plasma proteins. Note that there are also cases in which physiologic proteinuria occurs. These are usually due to alterations in the glomerular barrier and are typically transient in nature. Physiologic proteinuria may occur with exercise and fever. The exact mechanism is unknown, but may be due to alterations in renal hemodynamics.

ASSESSMENT OF PROTEINURIA Guidelines for Adults and Children It is usually not necessary to obtain a timed urine collection (overnight or 24-hour) for these evaluations in either children or adults. First morning specimens are preferred, but random specimens are acceptable if first morning specimens are not available. In most cases, screening with urine dipsticks is acceptable for detecting proteinuria: Standard urine dipsticks are acceptable for detecting increased total urine protein. Albumin-specific dipsticks are acceptable for detecting albuminuria. Patients with a positive dipstick test (1+ or greater) should undergo confirmation of proteinuria by a quantitative measurement (protein-to-creatinine ratio or albumin-to-creatinine ratio) within 3 months. Patients with two or more positive quantitative tests temporally spaced by 1 to 2 weeks should be diagnosed as having persistent proteinuria and undergo further evaluation and management for chronic kidney disease as stated in Guideline 2 Monitoring proteinuria in patients with chronic kidney disease should be performed using quantitative measurements.

PODS Library Underwear Toilet Training Proteinuria In Children Proteins are essential in our bodies. Normally, proteins move around in our blood, carrying food, hormones and medicine to all parts of the body. They also help keep water inside tiny blood vessels. A basic collection of urine Or 24 hour urine collection. This test helps show how well your child's kidneys are working. Your doctor may also do some blood tests. If a lot of protein is found in your child's urine, a more serious kidney disease might be the problem. Proteinuria doesn't cause pain. But when a lot of protein is in the urine, the level of protein in the blood may go down. This can cause swelling in your child's eyelids, ankles and legs. High blood pressure is another sign of this problem. What is Orthostatic Proteinuria ? Orthostatic proteinuria occurs in some older children and teenagers. The word orthostatic means "upright." The condition is called "orthostatic proteinuria" because protein goes into the urine only when the child is in the upright position (standing up). Children with this condition have no kidney damage but, for some unknown reason, they lose protein into the urine during the day when they are active. At night, while they sleep, their kidneys don't let any protein into the urine. Your doctor diagnoses this harmless condition by checking 2 urine samples. The first is collected in the morning, right after your child gets up. The second sample is collected throughout the day. The 2 samples are kept in separate containers. If your child has orthostatic proteinuria, the morning sample won't have protein in it, but the urine collected during the day will have protein in it.

Advertisement Welcome to Med Help! Questions in The Maternal and Child Health Forum are being answered by medical professionals from Henry Ford Health System , consistently ranked one of the best hospitals in America. Subject: Proteinuria Topic Area: Pregnancy - Abnormal Forum: The Maternal and Child Health Forum Question Posted By: Pam Summers on Saturday, January 09, 1999 I am a 28 year-old in my second pregnancy. I am currently 33 weeks pregnant. At approximately 25 weeks, I presented with a blood pressure of 153/96 at a routine examination. My blood pressure came down almost immmediately after lying on my left side and I have had no subsequent high BP's. However, we began doing 24-hour urine tests and I have had abnormal levels of protein in my urine. Levels of protein started at 186 and have now reached 409. I have had no other symptoms of preclampsia. Is it possible to be preclampsic without the high blood presssure? Is 409 a significant level of protein? Should I be consulting with a perinatalogist? What is your recommended course of action? Dear Pam Summers: Pre-eclampsia can have proteinuria without hypertension or edema (the three major signs), but this is uncommon: generally high blood pressure preceeds urine protein.

Hypertension Proteinuria MAMC Intranet or WRMC Internet Referral Guidelines Guideline Updated: April 2002 Specialty: Nephrology Proteinuria Referral Guideline Diagnosis/Definition Greater than 150 mg of proteinuria per day. Initial Diagnosis and Management Diagnosis is usually suspected on the basis of an abnormal dipstick urinalysis. The suspicion should be confirmed by either a 24-hour urine for protein or a spot urine protein to creatinine ratio of greater than 0.15 (equivalent to or greater than 150 mg of urinary protein daily). Proteinuria is a marker of intrinsic renal disease, and causes of this need to be assessed. Perform a history and physical examination to evaluate for evidence of a systemic disorder that may cause glomerulonephritis, i.e., signs/symptoms to suggest collagen vascular disease such as SLE, cancer, chronic infections, or diabetes. Evaluate for evidence of nephrotic syndrome: serum albumin (low), cholesterol (high), the presence of edema, and greater than 3 gm of proteinuria daily.

Why is the Test Performed? This test is most often performed when kidney disease is suspected. It may be used as a screening test. Normally, protein is not present in the urine when measured by routine dipstick qualitative tests. This is because the glomerulus (which is the part of the kidney nephron which filters fluid from the blood) generally prevents large molecules (which includes most proteins ) from entering the renal filtrate. Even if small amounts get through, they are normally taken up by renal tubular cells which then metabolize the proteins as a source of energy. However, even if both the glomerulus and renal tubules are completely normal, some proteins will appear in the urine if plasma (blood) concentrations exceed the threshold value.
