Are there causal relationships between the development of the inflammatory diseases amyotrophic lateral sclerosis and asthma?
Amyotrophic lateral sclerosis (ALS) and asthma are inflammatory diseases. ALS is a fatal progressive, neurodegenerative disease with inflammation around the upper and lower motor neurons leading to their degeneration, muscle atrophy, paralysis, and death. Asthma is a chronic inflammatory disease with reversible airway obstruction and nonspecific airway hyper-reactivity. The local release of sensory neuropeptides from capsaicin-sensitive primary afferents causes motor neuron pathophysiology and airway inflammation and hyper-reactivity. While there is no cure for ALS, asthma is managed according to its symptoms and severity, to decrease the symptoms, improve pulmonary function, and reduce morbidity. To determine whether understanding asthma may provide insights into how to clinically deal with ALS, the authors examined the etiologies of ALS and asthma, and the factors that exacerbate the symptoms. Although no direct correlations were found, the similar multifactorial triggers, and the critical roles of neuronal inflammation, suggest that one or more exists.
