Abstract

Estimado Editor:

Las úlceras del pie diabético (UPD) presentan una alta morbimortalidad y costos sanitarios elevados. La curación de estas lesiones a menudo se retrasa por la colonización microbiana, lo cual puede generar consecuencias como la amputación. En los estudios recientes se propone el uso de la terapia fotodinámica antimicrobiana (TFA) en las UPD. Esta terapia se basa en moléculas fotosensibilizadoras (fenotiazinio, verde de indocianina, ácido etilendiaminotetraacético) que generan especies reactivas de oxígeno capaces de inducir la destrucción de las células diana cuando se irradian con luz de una longitud de onda adecuada, para erradicar a microorganismos patógenos.

ABSTRACT

Dear Editor:

Diabetic foot ulcers (UPD) have high morbidity and mortality and high healthcare costs. The healing of these lesions is often delayed by microbial colonization, which can lead to consequences such as amputation. Recent studies propose the use of antimicrobial photodynamic therapy (TFA) in UPDs. This therapy is based on photosensitizing molecules (phenothiazinium, indocyanine green, ethylenediaminetetraacetic acid) that generate reactive oxygen species capable of inducing the destruction of target cells when irradiated with light of an appropriate wavelength, to eradicate pathogenic microorganisms.
