BACKGROUND. The prevalence of onychomycosis, the
most frequent cause of nail disease, ranges from 2% to 13%. Standard
treatments include debridement, topical medications, and systemic
therapies. This study assesses the efficacy and tolerability of
topical application of 1% clotrimazole solution compared with that
of 100% Melaleuca alternifolia (tea tree) oil for the treatment of
toenail onychomycosis. METHODS. A double-blind, multicenter,
randomized controlled trial was performed at two primary care health
and residency training centers and one private podiatrist's office.
The participants included 117 patients with distal subungual
onychomycosis proven by culture. Patients received twice-daily
application of either 1% clotrimazole (CL) solution or 100% tea tree
(TT) oil for 6 months. Debridement and clinical assessment were
performed at 0, 1, 3, and 6 months. Cultures were obtained at 0 and
6 months. Each patient's subjective assessment was also obtained 3
months after the conclusion of therapy. RESULTS. The baseline
characteristics of the treatment groups did not differ
significantly. After 6 months of therapy, the two treatment groups
were comparable based on culture cure (CL = 11%, TT = 18%) and
clinical assessment documenting partial or full resolution (CL =
61%, TT = 60%). Three months later, about one half of each group
reported continued improvement or resolution (CL = 55%; TT = 56%).
CONCLUSIONS. All current therapies have high recurrence rates. Oral
therapy has the added disadvantages of high cost and potentially
serious adverse effects. Topical therapy, including the two
preparations presented in this paper, provide improvement in nail
appearance and symptomatology. The use of a topical preparation in
conjunction with debridement is an appropriate initial treatment
strategy.
