Rapidly Progressive Glomerulonephritis (RPGN)

Pathophysiology of RPGN

1. Structure of the Kidneys: The kidneys are bean-shaped organs that filter blood and remove waste. The glomeruli are clusters of tiny blood vessels (capillaries?) where blood filtration begins.
2. Blood Supply: The kidneys receive blood through the renal? arteries?, which branch from the abdominal aorta?. This blood flows through the glomeruli, where waste products are filtered out.
3. Nerve Supply: The kidneys are innervated by the autonomic nervous system, which helps regulate blood flow and pressure within the kidneys.

Types of RPGN

RPGN is typically classified into three types based on the underlying causes:

1. Type I (Anti-Glomerular Basement Membrane Disease): Involves the immune system attacking the kidney’s basement membrane.
2. Type II (Immune Complex Disease): Caused by the deposition of immune complexes in the glomeruli (e.g., lupus? nephritis?, post-infectious glomerulonephritis).
3. Type III (Pauci-Immune Disease): Associated with small vessel vasculitis and does not show significant immune complex deposits.

Causes of RPGN

Here are 20 potential causes of RPGN:

1. Goodpasture’s Syndrome?: An autoimmune? disorder affecting the lungs and kidneys.
2. Systemic Lupus Erythematosus? (SLE?): A chronic? autoimmune disease? that can affect multiple organs.
3. Post-Infectious Glomerulonephritis: Often follows infections, especially with certain bacteria.
4. IgA Vasculitis (Henoch-Schönlein Purpura): A small vessel vasculitis that causes skin, joint, gut, and kidney issues.
5. Vasculitis: Inflammation of blood vessels affecting the kidneys.
6. Wegener’s Granulomatosis: A type of vasculitis affecting the kidneys and lungs.
7. Churg-Strauss Syndrome: An autoimmune disease causing asthma? and kidney inflammation.
8. Diabetes Mellitus?: Can lead to diabetic nephropathy.
9. Hypertension?: High blood pressure can damage kidney function.
