Post-Infectious Glomerulonephritis

Post-infectious glomerulonephritis is a type of kidney inflammation? that typically follows an infection, particularly those caused by certain bacteria or viruses. It is most commonly seen in children but can affect individuals of any age. The inflammation in the glomeruli? (tiny filters in the kidneys) leads to various symptoms and can result in complications if not treated properly.

Pathophysiology

Structure of the Kidneys

The kidneys are two bean-shaped organs located on either side of the spine, just below the rib cage?. Each kidney contains about a million tiny filtering units called nephrons?, which include glomeruli. The glomeruli filter waste and excess substances from the blood, producing urine.

Blood Supply

The kidneys receive blood through the renal? arteries?, which branch off from the aorta?. Once blood enters the kidneys, it passes through the glomeruli, where filtration occurs. After filtration, the blood is returned to circulation through the renal veins?.

Nerve Supply

The kidneys are supplied by both sympathetic and parasympathetic nerves, which help regulate blood flow and kidney function. The sympathetic nerves can constrict blood vessels in the kidneys, while parasympathetic nerves can promote relaxation and enhance kidney activity.

Types of Post-Infectious Glomerulonephritis

1. Acute? Post-Infectious Glomerulonephritis: This is the most common type, usually occurring after infections like streptococcal throat or skin infections.
2. Chronic? Post-Infectious Glomerulonephritis: Less common, this type can develop slowly over time, often following repeated infections or other underlying kidney conditions.

PIGN can be caused by various infections, including:

1. Streptococcus bacteria (most common)
