Nokea
Which condition involves the body's immune system attacking the lungs and kidneys, causing severe respiratory and renal damage?
Correct Answer: A
Rationale: Step-by-step rationale for A being correct:
1. Goodpasture syndrome is an autoimmune disease where the body produces antibodies against collagen in the lungs and kidneys.
2. Antibodies attack the basement membrane of the lungs and kidneys, leading to severe respiratory and renal damage.
3. Symptoms include coughing up blood, difficulty breathing, and kidney failure.
4. Treatment involves immunosuppressive therapy and plasma exchange to remove harmful antibodies.
Summary:
- B: Sarcoidosis involves granulomas in multiple organs but typically not lung-kidney damage.
- C: Wegener's granulomatosis affects the respiratory tract and kidneys but involves inflammation, not antibodies against collagen.
- D: Interstitial lung disease is a broad term for various lung conditions but doesn't specifically involve the immune system attacking lungs and kidneys.
