Abstract

Objective:

Although neurogenic cough is increasingly recognised, its pathophysiology remains obscure. We describe two cases of chronic cough following laryngeal herpes zoster, a rarely described manifestation of varicella-zoster virus reactivation, and suggest that this may be analogous to post-herpetic neuralgia. The same mechanisms may cause both phenomena.

Case reports:

We describe two cases of chronic cough persisting for more than three months following an acute attack of laryngeal herpes zoster.

Conclusion:

Neuronal damage by varicella-zoster virus results in irritable nociceptors and deafferentation, mechanisms known to cause post-herpetic neuralgia. When the vagus nerve is affected, as in laryngeal herpes zoster, the result may be a chronic cough. Similar damage may underlie chronic neurogenic cough in other contexts.
