Background:
Onychomycosis is a fungal infection of the fingernails and/or toenails, caused by dermatophytes, yeast and non-
dermatophyte moulds. The epidemiology of onychomycosis in Serbia is yet to be fully established.
Objectives:
This epidemiological study was aimed at evaluating the epidemiology of onychomycosis in a sample of the Serbian
patients at risk of onychomycosis, to determine the fungal aetiological agents and to identify the possible risk factors.
Patients & Methods:
The study population included 374 patients from six centers in Serbia with suspected onychomycosis.
Demographic data, data about comorbidities, lifestyle, clinical aspects of onychomycosis, trauma, excessive perspiration, and personal
and family history of previous onychomycosis were studied. Laboratory confirmation of diagnosis was done by direct microscopy,
fungal culture and PCR.
Results:
Diagnosis of onychomycosis was confirmed in 50.8% of patients, who tested positive to at least one laboratory test (direct
microscopy, fungal culture or PCR). T. rubrumwas predominant both on toenails (85.98%) and on fingernails (38.46%). Independent
risk factors for onychomycosis were: old age (OR=2.285; p<0.001), family history of previous onychomycosis and/or tinea pedis
(OR=2.452; p=0.005), excessive perspiration (OR=2.165; p=0.002), and higher degree of hyperkeratosis (OR=1.755; p=0.020).
Conclusions:
Identification of the most common causative agents of onychomycosis revealed the predominance of dermatophytes
and may be useful in discerning the epidemiological situation and planning preventive strategies. A significant contribution is insight
in the importance of certain conventional and methods of molecular biology in the diagnosis of onychomycosis since that for the first
time in Serbia molecular diagnosis was used in laboratory confirmation. These results could help in defining the optimal laboratory
protocols for reliably identification of onychomycosis suitable to our local epidemiology and the economic situation.
