Persistent Glomerulonephritis in Children
Persistent glomerulonephritis is abbreviated as protracted nephritis. The course of the disease is prolonged but the systemic symptoms are mild. In addition to the more common acute glomerulonephritis, nephrotic syndrome, isolated hematuria, and isolated proteinuria, there are some more chronic glomerulonephritis with varying degrees of severity, including protracted nephritis and chronic nephritis. The concept of protracted nephritis is not unified. The Pediatric Kidney Disease Collaborative Group of my country refers to acute nephritis with a protracted course of more than one year, if not accompanied by hypertension, renal insufficiency, or anemia, as protracted nephritis.
