Lambert-Eaton Syndrome

Aka: Lambert-Eaton Syndrome, Lambert Eaton Syndrome, Lambert-Eaton Myasthenic Syndrome
  1. Associated Conditions
    1. Cancer (esp. Small Cell Lung Cancer) in 50% of cases
  2. Pathophysiology
    1. Similar to Myasthenia Gravis (in that acetylcholine is not functional at Synapse)
    2. Calcium channel antibodies block acetylcholine release from presynaptic terminals
  3. Symptoms
    1. Proximal Muscle Weakness and Fatigue (better with use)
      1. Thighs and hips are most affected (contrast with initial bulbar symptoms of myasthenia)
  4. Management
    1. Plasmaphoresis
    2. Tumor resection
    3. Avoid provocative agents
      1. Neuromuscular blocking agents
      2. Aminoglycosides
      3. Intravenous Contrast dye

Lambert-Eaton Myasthenic Syndrome (C0022972)

Definition (MSHCZE) Paraneoplastický stav provázející malobuněčný bronchogenní karcinom plic připomínající klinicky myastenii (pseudomyastenie). Paraneoplastický syndrom charakterizovaný nervosvalovými poruchami a vegetativní dysfunkcí, svalová slabost, hyporeflexie, ptóza, xerostomie, ortostatická hypotenze, trávicí obtíže aj.. Podstatou je vznik autoprotilátek proti iontovým kanálům. (cit. Velký lékařský slovník online, 2013 http://lekarske.slovniky.cz/ )
Definition (NCI) A rare autoimmune presynaptic disorder characterized by impairment of the impulse transmission at the neuromuscular junction. It affects predominantly the proximal muscles of the lower extremities, resulting in muscle weakness and fatigability. It has been associated with small cell lung carcinoma.
Definition (MSH) An autoimmune disease characterized by weakness and fatigability of proximal muscles, particularly of the pelvic girdle, lower extremities, trunk, and shoulder girdle. There is relative sparing of extraocular and bulbar muscles. CARCINOMA, SMALL CELL of the lung is a frequently associated condition, although other malignancies and autoimmune diseases may be associated. Muscular weakness results from impaired impulse transmission at the NEUROMUSCULAR JUNCTION. Presynaptic calcium channel dysfunction leads to a reduced amount of acetylcholine being released in response to stimulation of the nerve.
