Summary

Onychomycosis (fungal nail infection) monotherapy often leads to relapse. Combination antifungal therapies, combining oral and topical treatments, show improved long-term cure rates compared to single-drug approaches.

A survey among dermatologists: diagnostics of superficial fungal infections - what is used and what is needed to initiate therapy and assess efficacy?

Journal of the European Academy of Dermatology and Venereology : JEADV·2018

Area of Science:

  • Mycology
  • Dermatology
  • Pharmacology

Background:

  • Onychomycosis (fungal nail infection) presents a significant challenge in treatment due to high relapse rates with monotherapy.
  • The LION Study's Icelandic cohort indicated low long-term disease-free rates (46% for terbinafine, 13% for itraconazole) after 5 years, highlighting the limitations of monotherapy.

Purpose of the Study:

  • To evaluate the efficacy of combination antifungal therapies for onychomycosis.
  • To compare combination therapy outcomes against monotherapy in managing fungal nail infections.

Main Methods:

  • Review of existing combination therapy trials for onychomycosis.
  • Analysis of drug combinations including oral and topical antifungal agents.
  • Consideration of sequential versus parallel administration strategies.

Main Results:

  • Combination therapy is generally advantageous over monotherapy for onychomycosis treatment.
  • Specific combinations like amorolfine with terbinafine or itraconazole show promise.
  • Parallel therapy is suggested for high-risk patients (e.g., diabetics), while sequential therapy suits non-responders.

Conclusions:

  • Combination antifungal therapy offers superior outcomes for onychomycosis compared to monotherapy.
  • Strategic administration (sequential or parallel) can optimize treatment success based on patient risk factors.
  • Further research with standardized trial durations is needed to definitively compare various combination regimens.
