BACKGROUND: An open-label, noncomparative study was conducted to assess the safety and efficacy of ciclopirox 8% nail lacquer topical solution in patients with type 2 diabetes mellitus.
METHODS: Forty-nine diabetic patients with distal subungual onychomycosis were treated once daily for 48 weeks with ciclopirox 8% nail lacquer, a topical nail solution approved for the treatment of patients with mild-to-moderate onychomycosis.
RESULTS: Treatment resulted in clinical improvement in 63.4% of patients. Most patients (85.7%) had a mycologic outcome of improvement or cure, with 54.3% attaining mycologic cure. Consideration of mycologic and clinical outcomes generated a treatment outcome of improvement, success, or cure in 84.4% of patients. Moreover, patients experienced improvement in the diseased area of the nail (63.4%), nail surface (56.1%), nail color (48.8%), and nail thickness (65.9%). Ciclopirox 8% nail lacquer was safe, with treatment-related adverse events limited to infection in one patient, which resolved in 15 days; the patient completed the study. No treatment-related serious adverse events were observed.
CONCLUSION: Ciclopirox 8% nail lacquer is a safe and effective treatment for distal subungual onychomycosis in patients with type 2 diabetes mellitus receiving insulin or oral hypoglycemic therapy.
