QBank

A 23-year-old man comes to the emergency department with paresthesias and progressive weakness in his legs. He first noticed the weakness 3 days ago, and now he has difficulty walking. The patient has no history of trauma, but he had an upper respiratory infection 2 weeks ago. He has no significant past medical history and takes no medications. His temperature is 37.2 C (99 F), blood pressure is 130/80 mm Hg, pulse is 80/min, and respirations are 14/min. On physical examination, the patient has decreased strength in his lower extremities and is unable to walk without assistance. Deep tendon reflexes are absent in the lower extremities. The remainder of the physical examination is unremarkable. A nerve biopsy is performed. Histologic examination of the specimen is most likely to reveal which of the following?
A. Vasculitis with fibrinoid necrosis
B. Endoneurial lymphocytes and macrophages
C. Epineurial granulomas
D. Perineurial plasma cells
E. Segmental demyelination with no inflammation

Flashcards

Guillain-Barré syndrome classically presents with symmetric ascending weakness

Guillain-Barré syndrome (GBS) is an acute inflammatory polyneuropathy often triggered by infections such as Campylobacter jejuni, cytomegalovirus, or Epstein-Barr virus.

Key features include:

  • Symmetric weakness: Begins in the lower limbs and ascends, potentially leading to paralysis.
  • Paresthesias: Abnormal sensations starting in the feet and hands and moving upwards.

Severe GBS can lead to respiratory failure due to paralysis of respiratory muscles, which is the most common cause of death. Diagnosis is confirmed by cerebrospinal fluid showing albuminocytologic dissociation and nerve conduction studies.

Treatment involves supportive care, monitoring for respiratory failure, and specific therapies such as intravenous immunoglobulin (IVIG) or plasma exchange. IVIG is generally preferred over plasma exchange due to its ease of administration, fewer side effects, and equal efficacy in reducing the severity and duration of the illness.
