Goodpasture Syndrome

Pathophysiology

Structure Involved:

• Kidneys: The immune system attacks the glomeruli, which are tiny filtering units in the kidneys responsible for removing waste from the blood.
• Lungs: The immune system targets the alveoli, the tiny air sacs where gas exchange occurs.

Blood:

Autoantibodies (anti-GBM antibodies) are produced against the glomerular basement membrane in the kidneys and the alveolar basement membrane in the lungs. These antibodies activate the complement system, leading to 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? and tissue damage.

Nerve Supply:

Goodpasture Syndrome primarily affects the kidneys and lungs, which are not directly involved with the nervous system. However, severe illness can lead to systemic? effects impacting overall neurological function indirectly.

Types of Goodpasture Syndrome

Goodpasture Syndrome is generally categorized based on the organs affected:

• Classic Goodpasture Syndrome: Involves both the kidneys and lungs.
• Renal? Goodpasture Syndrome: Primarily affects the kidneys.
• Pulmonary Goodpasture Syndrome: Primarily affects the lungs.

Causes of Goodpasture Syndrome

Goodpasture Syndrome is an autoimmune? disorder, meaning the exact cause isn’t entirely understood. However, several factors may contribute:
