The role of oxidative stress in onychomycosis: Thiol/disulphide homeostasis.

Patients with onychomycosis showed a shifted thiol/disulphide homeostasis towards oxidative stress with a reduction in thiols and an increase in disulphide/native thiol, and disulphide/total thiol ratios. These findings may indicate the role of oxidative stress in the pathogenesis of onychomycosis.
