Lambert-Eaton myasthenic syndrome (LEMS) — rare presynaptic neuromuscular junction (NMJ) autoimmune disorder; anti-P/Q-type voltage-gated calcium channel (VGCC) antibodies (VGCC-Ab, ~85% LEMS) → reduced Ca2+ entry at motor nerve terminal → impaired acetylcholine (ACh) vesicle exocytosis → proximal limb weakness (legs > arms, characteristic Lambert sign — brief facilitation with repetitive stimulation/exercise, distinguishing from MG); autonomic dysfunction (dry mouth, impotence, constipation); paraneoplastic LEMS (~50-60%): SCLC (small cell lung cancer, most common) — SCLC expresses neuronal VGCC → tumor-triggered anti-VGCC Abs; non-paraneoplastic LEMS (~40-50%): HLA-B8/DR3 associations; EMG: low-amplitude CMAPs with increment >100% at high-frequency stimulation (50 Hz); VGCC-Ab titer; 3,4-diaminopyridine (3,4-DAP, amifampridine — FDA 2019 LEMS, blocks K+ channels → prolonged action potential → enhanced ACh release); pyridostigmine (AChE inhibitor, weak effect); IVIG; plasma exchange; immunosuppressants (prednisone, azathioprine); anti-tumor treatment (if SCLC).
