In nephritic syndrome the following features indicate poor prognosis except -
ACUTE NEPHRITIC SYNDROME. This is the acute onset of haematuria, proteinuria, hypeension, oedema and oliguria following an infective illness about 10 to 20 days earlier. 1. The haematuria is generally slight giving the urine smoky appearance and erythrocytes are detectable by microscopy or by chemical testing for haemoglobin. Appearance of red cell casts is another classical feature of acute nephritic syndrome. 2. The proteinuria is mild (less than 3 gm per 24 hrs) and is usually non-selective (nephritic range proteinuria). 3. Hypeension is variable depending upon the severity of the glomerular disease but is generally mild. 4. Oedema in nephritic syndrome is usually mild and results from sodium and water retention. 5. Oliguria is variable and reflects the severity of glomerular involvement. The underlying causes of acute nephritic syndrome may be primary glomerulonephritic diseases (classically acute glomerulonephritis and rapidly progressive glomerulonephritis) or ceain systemic diseases Ref: Harsh Mohan textbook of pathology 6th Ed. page 660
