Glomerulonephritis Is a bilateral inflammatory kidney disease that mainly affects glomeruli. They are the basic functional unit of the kidney tissue, which provides the cleansing function in the body and, on the other hand, they are essential for the maintenance of the acid-alkaline and electrolyte equilibrium. Due to the proper functioning of the glomeruli from the blood, unnecessary and redundant substances are cleansed, while maintaining the necessary constituents and structures such as protein molecules and erythrocytes. This is why the damage to glomeruli is associated with a serious impairment of normal kidney function and hence of the whole organism. In some cases, glomerulonephritis may be a secondary manifestation, i. They arise on the basis of the underlying disease. In most cases, however, it is primary glomerulonephritis, the cause of which remains unclear. Additionally, depending on the course of development, glomerulonephritis can be acute and chronic. Some of the sharp forms have a good prognosis and with appropriate therapy are subject to complete cure. However, chronic gemoralonephritis is the third cause of end-stage renal failure requiring hemodialysis treatment. This makes the disease extremely serious and requires rapid and adequate therapeutic measures to control symptoms and prevent possible kidney failure.
