Rapidly Progressive Glomerulonephritis (RPGN)

Key Points:

• Glomeruli: Tiny filters in the kidneys.
• Rapid Progression: Kidney function declines quickly, often over weeks to months.

Pathophysiology of RPGN

Structure

The kidneys consist of:

• Glomeruli: Filters blood.
• Tubules: Reabsorb necessary substances and excrete waste.
• Interstitium: Supportive tissue around the tubules.

Blood Supply

The kidneys receive blood through the renal? arteries. Adequate blood flow is crucial for maintaining kidney health. In RPGN, damage to glomeruli can disrupt this blood supply.

Nerve Supply

The kidneys are innervated by the autonomic nervous system, which helps regulate functions such as blood pressure and filtration rate. Damage or infection?, or irritation, often causing pain?, swelling?, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation? in the kidneys can affect these functions.

Types of RPGN

RPGN can be classified into three main types based on the underlying cause:

1. Type I: Anti-GBM Disease
   • Caused by antibodies attacking the glomerular basement membrane.
2. Type II: Immune Complex Disease
   • Results from the buildup of immune complexes in the glomeruli. Common causes include:
     • Lupus nephritis
     • IgA nephropathy
3. Type III: Pauci-Immune Disease
   • Involves the presence of few immune complexes. Often associated with vasculitis.
