Definition of Acute glomerulonephritis

Acute glomerulonephritis: one of a group of kidney diseases characterized by the abrupt onset of inflammation and proliferation of the glomeruli, microscopic structures within the kidney that are responsible for filtering the blood and producing urine. Acute glomerulonephritis can result in long-term damage or may resolve, depending upon the cause and severity. Acute poststreptococcal glomerulonephritis is the prototype condition of this group. This condition involves inflammation of the kidney that occurs following an infection with Streptococcus bacteria, such as strep throat. Other conditions that can cause acute glomerulonephritis include systemic lupus erythematosus, Goodpasture's syndrome, Wegener's disease, and polyarteritis nodosa.
