Azotemic or Hydropic Glomerulonephritis

The high concentration of non protein nitrogen (NPN) in the blood of a patient, mainly due to elevated level of urea is termed as azotemia. Elevated level of urea in blood is termed as uremia and it may be due to renal abnormality or due to other health problems like dehydration and excessive burns on the body. The glomerulonephritis (inflammation of glomeruli of kidneys) may be azotemic or hydropic type depending on the nature of glomerular lesions. There may be marked narrowing of the glomerular capillaries leading to azotemia with renal insufficiency and hypertension. On the other hand the status of glomerular capillaries may remain normal but there could be an increase in the permeability of glomerular basement membrane (GBM), the filtration barrier of kidneys. The clinical picture would be hydropic (accumulation of water in the tissues of the body) in character. The hydropic glomerulonephritis is clinically represented with edema associated with hypoproteinemia (low level of protein in blood) and hyperlipemia (high concentration of lipids or cholesterol in blood).

A child or an adult affected with fever or some other acute disease finds the increase in the daily output of urine. There may be tinge of blood in the urine of the patient affected by glomerulonephritis. Sudden appearance of features like puffiness or swelling on face (facial edema), ankles and hands after any acute disease needs expert medical attention and medication. The urine of such patients would show notable excretion of albumin. The patient may be less perspiring with dry skin. The pulse could be full and hard. The loin pain and a feeling of heaviness in the lower abdominal region are the associated symptoms. The polyuria (excessive output of urine) is probably compensatory action of affected kidneys to flush out solid wastes of metabolism form the body. An effective therapy would definitely reverse the associated symptoms and lesions.
