Study Notes
Autoimmune Disorders
Guillain-Barré Syndrome
- Follows viral infection (URTI, GIT) or swine flu immunization
- Affects all age groups and sexes
- Causes: Campylobacter jejuni, Cytomegalovirus, Epstein-Barr virus, Mycoplasma pneumoniae, Haemophilus influenzae, HIV
- Histology: Nerve infiltrated lymphoid cells with phagocytosis of myelin by macrophages
- Clinical features:
- Ascending muscle weakness and paralysis
- Respiratory failure possible
- Less prominent sensory changes
- Remyelination over 3-4 months
- Diagnostics:
- EMG
- CSF Analysis
- CT scan/MRI
- Management:
- Maintain airway and support pulmonary function
- Prepare patient for Plasmapheresis during acute phase
- Pharmacologic treatment: Steroids, IV IgG, Anti-arrhythmic, Propranolol
- Encourage patient to move around to prevent complications due to immobility
- Prevent Contractures and atrophy
- Prevent DVT
- Provide Nutritional support
- Safe environment to minimize infection
- Emotional support
Multiple Sclerosis
- Chronic, debilitating, progressive disease with periods of remission and exacerbation
- Characterized by randomly scattered patches of demyelination
- Common in females of 20-40 years old
- Etiology:
- Autoimmune response
- Environmental factors (Vitamin D levels)
- Genetics (HLA)
- Infection by a slow latent virus
- Manifestations occur intermittently and depend on CNS involvement
- Blood-Brain Barrier Breakdown: Leaks form in the blood-brain barrier, allowing immune cells to infiltrate
- Pathology:
- Immune response leads to recurrent inflammatory reactions
- Lymphocytes secrete IgG antibodies, which increase during exacerbations
- Macrophages enter the myelin sheath, removing degenerating myelin, forming patchy areas of demyelination
- Areas of Plaque Formation:
- Corticospinal syndrome
- Generalized muscle weakness
- Muscle wasting and atrophy
- Diagnostics:
- Electromyography
- Blood tests (CRH modulator antibodies)
- Chest x-ray/CT Scan
- Edrophonium Chloride (Tensilon test)
