    Abstract:
    BACKGROUND: Nondermatophyte mold (NDM) onychomycosis shows poor response to current topical, oral or device-related antifungal therapies. This study was aimed to determine the efficacy and safety of itraconazole and terbinafine pulse therapy on NDM onychomycosis. METHODS: Mycologically proven subjects were treated with itraconazole 400 mg daily or terbinafine 500 mg daily for 7 days/month; two pulses for fingernails and three pulses for toenails(SLCTR/2013/013). RESULTS: One-hundred seventy-eight patients underwent mycological studies and 148 had positive fungal isolates. NDM were the prevailing fungi, 68.2%, followed by candida species 21.6%, and dermatophytes made up only 10.1%. Out of NDM Aspergillus spp (75.1%) predominated followed by 8.9% Fusarium spp and 4.95% Penicillium spp. The clinical cure at completion of pulse therapy was statistically significant 9.2% versus 2.0% (p < 0.05) in itraconazole group. But no statistically significant difference was detected between the two regimens at the end of 12 months; 65.1% versus 54.64%. Recurrences observed in both groups (6.5% vs. 4.1%) were not statistically significant. With itraconazole pulse 68.22% Aspergillus spp, 50.0% Fusarium spp and 84.6% Penicillium spp showed clinical cure, while terbinafine pulse cured 55.0% Aspergillus spp and 50.0% Fusarium spp. CONCLUSIONS: NDM was the prevailing fungi in onychomycosis in Sri Lanka. Both itraconazole and terbinafine were partially effective on NDM onychomycosis showing a clinical cure of 54-65%. Future research should focus on searching more effective antifungal for NDM onychomycosis.
