Treatments for Onychomycosis: A Bibliometric Analysis.

INTRODUCTION

Oral antifungals were the earliest treatments to receive approval for the management of onychomycosis and have a long-standing record to support their efficacy. Topical antifungals and device-based treatments have been explored and some implemented in more recent years as alternatives to traditional oral antifungals. The present bibliometric analysis summarizes trends in publication frequency for onychomycosis treatment modalities over time and characterizes their body of literature in terms of types of studies available and relative level of evidence.

METHODS

A comprehensive literature search was performed using Web of Science and SCOPUS databases.

RESULTS

Covering all publications from 1970 to present day, our search identified oral therapeutics = 295 articles ( = 63 randomized control trials [RCTs]), topical therapeutics = 358 articles ( = 72 RCTs), and device-based treatments = 158 articles ( = 37 RCTs). Spikes in research activity surround FDA approval of therapeutics for each treatment modality. Research activity within the last decade has focused on topical and device-based treatments. Evidence for efficacy of device-based treatments is lacking from relatively few high-quality RCTs.

CONCLUSION

With growing concern for non-dermatophyte mold onychomycosis and terbinafine resistance, researchers should validate the efficacy and safety of device-based treatments with high-quality studies.
