proteinuria

 [pro″te-nu´re-ah]
an excess of serum proteins in the urine, such as in renal disease, after strenuous exercise, or in dehydration.
accidental proteinuria (adventitious proteinuria) proteinuria due not to a kidney disease but to some other condition such as hemorrhage in the urinary tract; called also false proteinuria.
athletic proteinuria effort proteinuria.
dietetic proteinuria (digestive proteinuria) functional proteinuria produced by the eating of certain foods.
effort proteinuria functional proteinuria occurring as a result of vigorous and prolonged exercise of the lower limbs; called also athletic proteinuria.
false proteinuria adventitious proteinuria.
functional proteinuria any proteinuria that is not due to renal disease, such as the transient proteinuria of pregnancy, effort proteinuria, and orthostatic proteinuria.
glomerular proteinuria the most common kind of proteinuria, being due to glomerular disease and abnormal permeability of the glomerular capillaries to protein.
orthostatic proteinuria a form of functional proteinuria, usually seen between the ages of ten and twenty, that occurs on standing erect and disappears on lying down.
overflow proteinuria that due to hemoglobin, myoglobin, or immunoglobulin loss into the urine due to excessive amounts in the bloodstream, such as in multiple myeloma; it is not usually associated with glomerular or tubular disease.
tubular proteinuria proteinuria due to excretion of proteins of low molecular weight such as immunoglobulins, which normally should be reabsorbed.

glomerular proteinuria

Loss of protein (primarily albumin and other large molecules) in the urine because of defects in the glomerular capillary membranes of the kidneys.

The appearance of tubular proteinuria may precede glomerular proteinuria in critically ill patient with AKI.6 Thus tubular proteinuria appeared to be a more reliable marker than glomerular proteinuria in predicting the length of interim support for critically patients who has AKI.13
In summary SDS-PAGE analysis is shown to be a cheap and reliable method in defining the presence of tubular and glomerular proteinurias in severe AKI patients requiring aRRT in ICUs.
By contrast, the marker protein approach revealed a mixed pattern of predominantly glomerular proteinuria as well as increased tubular marker proteins.
The excretion pattern of glomerular proteinuria has diagnostic and prognostic significance.
Eight samples were identified as glomerular proteinuria, either selective (n = 5) or not selective (n = 3); the total protein was 390 [+ or -] 88 and 4500 [+ or -] 133 mg/24 h, respectively.
