Abstract:
Recently, there has been a resurgence of interest in potential phototherapy technologies for the local treatment of bacterial and fungal infection. Currently, onychomycosis is the principle disease that is the target of these phototherapies in podiatric medicine. Some of these technologies are currently undergoing in vitro and in vivo trials approved by institutional review boards. The three light-based technologies are ultraviolet light therapy, near infrared photo-inactivation therapy, and photothermal ablative antisepsis. Each of these technologies have markedly dissimilar mechanisms of action. In this review, each technology will be discussed from the perspectives of history, photobiology, individual mechanism of action, safety, and potential clinical efficacy, with data presented from published material. This review is intended to give podiatric physicians detailed information on state-of-the-art infectious disease phototherapy.
Insights
Phototherapy shows promise for treating nail infections like onychomycosis. This review details three light-based methods: ultraviolet light, near-infrared photo-inactivation, and photothermal antisepsis, evaluating their mechanisms, safety, and efficacy.
Area of Science:
- Podiatric medicine
- Photobiology
- Infectious disease treatment
Background:
- Onychomycosis is a common fungal infection targeted by new podiatric treatments.
- Phototherapy is experiencing a revival for localized bacterial and fungal infections.
Purpose of the Study:
- To review state-of-the-art phototherapy technologies for podiatric physicians.
- To provide detailed information on the history, mechanisms, safety, and efficacy of light-based treatments.
Main Methods:
- Review of published data on three distinct phototherapy technologies.
- Discussion of ultraviolet light therapy, near-infrared photo-inactivation therapy, and photothermal ablative antisepsis.
- Analysis of each technology's photobiology and mechanism of action.
Main Results:
- The three technologies (UV, NIR, photothermal) have different mechanisms of action.
- In vitro and in vivo trials are underway for some of these therapies.
- Data on safety and potential clinical efficacy are presented from existing literature.
Conclusions:
- Phototherapy offers potential for treating onychomycosis and other infections.
- Understanding the distinct mechanisms, safety profiles, and efficacy is crucial for clinical application.
- Further research and trials are supporting the advancement of these light-based therapies in podiatry.
