Distal and lateral toenail onychomycosis caused by Trichophyton rubrum: treatment with photodynamic therapy based on methylene blue dye

Abstract: The study showed the effectiveness of photodynamic therapy based on methylene blue to treat severe distal and lateral subungual toenail onychomycosis. 22 patients were divided into two groups: group A consisting of 11 patients with severe toenail onychomycosis and group B consisting of 11 patients with mild-to-moderate toenail onychomycosis. All patients had onychomycosis caused by Trichophyton rubrum. The patients were treated with sessions of 2% methylene blue aqueous solution irradiated with light emission … Show more

“…Most authors reported a clinical and microbiological cure rate of 90-100% following treatments. PDT efficacy depends however on the pretreatment of the nail with urea and/or mechanical abrasion to increase its permeability to the photosensitizing agent and active removal of hyperkeratosis [85,87] .…”

“…Also, the authors of one study point out that the clinical response to PDT was superior in the treatment of mild and moderate mycosis (100%) to severe toenail onychomycosis (63.3%). Importantly, the highest cure rate has been observed in patients with the distal-lateral type of onychomycosis and endonyx onychomycosis which is a relatively rare presentation of the disease [26][27][28].…”

“…Ponadto opublikowano badanie, w którym uzyskano lepszą odpowiedź kliniczną w przypadku zastosowania PDT w leczeniu grzybicy o łagodnym i umiarkowanym nasileniu (100%) niż grzybicy paznokci stóp o znacznym nasileniu (63,3%). Największy odsetek wyleczeń obserwowano u pacjentów z odmianą dystalno-boczną oraz wewnątrzpłytkową, która jest dość rzadka [26][27][28].…”

“…[47] z zastosowaniem terapii fotodynamicznej (LED 630 nm, preparat fotouczulający -2% błękit metylenowy) wykazano dobre efekty terapii u 22 chorych. Ciężka postać grzybicy dystalno-bocznej paznokci jest trudna do wyleczenia każdą ze stosowanych metod.…”

“…Ciężka postać grzybicy dystalno-bocznej paznokci jest trudna do wyleczenia każdą ze stosowanych metod. Dlatego nie dziwi fakt, że terapia tej postaci za pomocą metody fotodynamicznej z użyciem błękitu metylenowego była mniej skuteczna niż terapia postaci średnio nasilonej, w której wskaźnik wyleczeń sięgał 100% [47].…”
