HPV - infected cells because they are metabolically more active, can be better affected by this technique, promoting an alternative topic treatment for Cervical Intraepithelial Lesions (CIN). The present prospective and randomized study compared three PDT protocols applied to 31 patients with high-grade CIN and infected by HPV. Protocols used LEDs with a wavelength of 630 nm and a fluence of 150 J/cm<sup>2</sup> as a light source, with different number of sessions and intervals between the three groups. There was no statistical difference between the protocols, however, we noticed a clinical difference that indicates a better response to PDT in the treatment with two PDT sessions, and an interval of 21 days between sessions. In this protocol, after 120 days of therapy, 50 % of patients had a regression in the lesion, presenting cytology compatible with CIN I or chronic cervicitis and after 6 months there was an 80 % cure rate. Furthermore, 50 % of patients who, before treatment, were carriers of high-risk HPV had a complete viral load clearance. Therefore, we conclude that a greater number of sessions, as well as a longer interval between the treatments day, is an efficient method to enhance the results of PDT, allowing more time for regeneration and viral clearance of the cervical tissue.</div></div>","PeriodicalId":20141,"journal":{"name":"Photodiagnosis and Photodynamic Therapy","volume":"53 ","pages":"Article 104603"},"PeriodicalIF":3.1,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143906370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional treatment for MG typically involves a combination of systemic oral antifungal drugs and topical medications; however, this approach often results in a low cure rate, high recurrence rate, and significant adverse effects. In contrast, 5-aminolevulinic acid photodynamic therapy (ALA-PDT), which has emerged as a novel strategy for treating fungal infections, is being increasingly utilized in the management of infectious granulomas.</div></div><div><h3>Methods</h3><div>A patient with refractory MG caused by Trichophyton mentagrophytes (<em>T. mentagrophytes</em>) received three cycles of ALA-PDT.

Cytokine analyses were performed under conditions where the compound was applied in the dark and under 5 and 10 min light exposure. The data show that the porphyrin derivative exhibits a significant anti-inflammatory photodynamic effect in vitro when applied at subtoxic concentrations. No cytotoxicity was observed at all applied doses, both in the presence and absence of light. This is consistent with previous literature findings demonstrating the non-cytotoxic nature of porphyrin derivatives. While high-concentration POR applications create a strong anti-inflammatory response in dark conditions, a significant decrease in TNF-α and IL-6 release was recorded with light application. Furthermore, the observed effects were dose-dependent, highlighting the critical importance of optimizing the dose for potential therapeutic uses.
