Clinical Trial Summary

This study aims to assess if laser treatment can cure fungal infection in toenails. Nail clippings from eligible subjects were obtained and randomised into two groups. All nail clippings were treated once with a 1064 nm Nd:YAG-laser. Before and after treatment, nail clippings were tested for fungal infection by microscopy and by culture.


Description:

This study was carried out as a randomised controlled trial (RCT) including two treatment groups subjected to two different laser treatments. A 1064 nm Nd:YAG-laser (Candela Medical, Ellipse Nordlys (Nd:YAG 1064), USA) was used for all treatments. Potential subjects were recruited from general practitioners and skin clinics in North Jutland from August 24th, 2021, through December 2021. All interventions and mycological tests for each subject were performed over the course of one day. After subjects were included, toenails with a clinical suspicion of onychomycosis (OM) were tested for fungal infection by culture and microscopy. At the same time, nail clippings from said toenails were obtained and randomised into one of two treatment groups, i.e., group A and group B. The nail clippings were then treated with a 1064 nm Nd:YAG-laser with laser settings as specified by the treatment groups. All nail clippings were treated only once. Immediately after treatment, nail clippings were again tested for fungal infection by culture and microscopy.

Outcome

Type Measure Description Time frame Safety issue
Primary Fungal infection status in nail clippings measured by microscopy after laser treatment. The number (rate) of included nail clippings in each group that were found negative for fungal infection measured by microscopy after therapy. Approximately 10 minutes after treatment
Primary Fungal infection status in nail clippings measured by culture after laser treatment. The number (rate) of included nail clippings in each group that were found negative for fungal infection measured by culture after therapy. Approximately 10 minutes after treatment
Primary Fungal infection status in nail clippings measured by microscopy before laser treatment. The number (rate) of included nail clippings in each group that were found negative for fungal infection measured by microscopy before therapy. Approximately 10 minutes before treatment
Primary Fungal infection status in nail clippings measured by culture before laser treatment. The number (rate) of included nail clippings in each group that were found negative for fungal infection measured by culture before therapy. Approximately 10 minutes before treatment
Secondary Fungal infection status in nail clippings measured by PCR before laser treatment. The number (rate) of included nail clippings in each group that were found negative for fungal infection measured by PCR before therapy. Approximately 10 minutes before treatment
Secondary Fungal infection status in nail clippings measured by PCR after laser treatment. The number (rate) of included nail clippings in each group that were found negative for fungal infection measured by PCR after therapy. Approximately 10 minutes after treatment
Secondary Nail clippings temperatures Nail clippings temperature measured at the end of treatment Approximately 2 seconds after end of treatment.
