Review of the Diagnostic Challenges of Lambert–Eaton Syndrome Revealed Through Three Case Reports

Abstract: Lambert-Eaton syndrome (LES) is a rare immune-mediated disorder characterized by proximal leg weakness, autonomic symptoms and hypoactive tendon reflexes. The paraneoplastic form is associated with small-cell lung cancer in 50-60% of cases, whereas the remaining cases are found in younger adults with a higher likelihood of coexisting autoimmune disease. The early recognition of LES is crucial for improving clinical outcomes but remains a major challenge. In this review, we analyze the clinical characteristics … Show more

“…SSR, a non-invasive measure to assess sympathetic cholinergic sudomotor function, has not been widely performed on LEMS patients. To date, only two case reports [ 9 , 10 ] have mentioned SSR test on LEMS patients, and one study suggests the absence of SSR in 18 out of 33 cases [ 11 ]. None of them describe the detailed results of the test as we do in the current presentation.…”

“…Los síntomas oculares y bulbares son menos frecuentes y como se indica éstos se reportan mayormente con la progresión avanzada de la enfermedad, entre los que se citan ptosis, diplopia, disartria y disfagia (6,11,14). Menos del 10% de pacientes con SMLE pueden desarrollar degeneración cerebelosa manifestando ataxia, encefalitis límbica y neuropatía sensorial (8,14,15,16). Dentro de las disfunciones autonómicas que se describen se encuentran constipación, alteración pupilomotora, xerostomía, disfunción erectil y anormalidades en la sudoración hasta en un 30% de los pacientes (1,2,5,15,17).…”

Algunos síntomas constitucionales pueden estar presentes como parte de la malignidad subyacente, como lo son pérdida de peso y anorexia (10,16).…”
