Abstract

BACKGROUND
Onychomycosis is a chronic fungal nail disease that may have a profound effect on quality of life (QOL).
OBJECTIVE
The purpose of this study was to evaluate the QOL in patients with toenail onychomycosis using the onychomycosis quality of life questionnaire (ONYCHO) and to determine the factors influencing the QOL of toenail onychomycosis patients.
METHODS
A total of 102 adults (mean age, 59.54 years) with toenail onychomycosis who visited our department between July 2017 and June 2018 completed the ONYCHO, which consists of statements pertaining to social, emotional, and symptom problems. All patients with toenail onychomycosis had been diagnosed by positive direct microscopic examination.
RESULTS
Most of the patients demonstrated significantly reduced QOL. The degree of QOL impairment differed between subgroups. Both social (p<0.01) and emotional (p<0.05) impairments were more conspicuous in the female than in the male patients, although there were no differences according to symptoms. Patients with more extent of toenail involvement were more affected by onychomycosis in all three ONYCHO scales (p for trend<0.05). In terms of the type of toenail onychomycosis, the degrees of social (p for trend<0.05), emotional (p for trend<0.05), and symptom (p for trend<0.01) impairment were more prominent in patients with total dystrophic onychomycosis than in those with superficial white onychomycosis and distal and lateral subungual onychomycosis. A tendency toward better QOL in terms of social problems, but not emotional or symptom problems, was associated with a longer duration of the disease (B, 8.95, 95%CI, 0.99-16.91).
CONCLUSION
Although toenail onychomycosis is not a life-threatening disease, it has a significantly negative impact on the overall QOL of patients, which should be a focus of concern.
