Comparison of blue laser and red light-emitting diode-mediated aminolevulinic acid-based photodynamic therapy for moderate and severe acne vulgaris: A prospective, split-face, nonrandomized controlled study. Photodiagnosis Photodyn Ther 2024; 49:104325. [PMID: 39245305 DOI: 10.1016/j.pdpdt.2024.104325] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2024] [Revised: 08/21/2024] [Accepted: 08/28/2024] [Indexed: 09/10/2024]
Abstract
BACKGROUND Acne is a chronic inflammatory skin disease. Photodynamic therapy (PDT) is a highly effective and safe drug-device combination treatment, typically using red and blue light. However, direct comparisons of aminolevulinic acid (ALA)-based PDT using these two light sources are lacking. Therefore, we compared the efficacy and adverse effects of ALA-based 450 nm blue laser-mediated PDT (BL-PDT) and 630 ± 10 nm red light-emitting diode-mediated PDT (RL-PDT) in the treatment of moderate-to-severe acne vulgaris, including analyses of different lesion types. METHODS Sixteen patients with moderate-to-severe acne vulgaris were recruited. All patients underwent BL-PDT on the left side of the face and RL-PDT on the right side. Treatments were administered thrice at 2-week intervals, and follow-up continued for 2 weeks after the final treatment. The average rates of improvement in inflammatory and non-inflammatory acne lesions, IGA (Investigator's Global Assessment) scales, and IGA success rates were calculated. In addition, adverse effects during and after each treatment were recorded. RESULTS At the 2-week follow-up after the final treatment, the average rates of improvement in total acne, inflammatory, and non-inflammatory lesions were 48.0 %, 63.0 %, and 30.0 % in the BL-PDT group and 42.2 %, 58.1 %, and 27.5 % in the RL-PDT group, respectively. The IGA scores for the two groups decreased by 1.8 and 1.7 points, respectively, and the IGA success rate was 53.3 % in both groups. There were no significant differences between the BL-PDT and RL-PDT groups in any measure of effectiveness. However, the BL-PDT group exhibited more severe adverse effects, especially pain and hyperpigmentation. CONCLUSIONS BL-PDT and RL-PDT have similar efficacies in moderate-to-severe acne vulgaris and are particularly effective for inflammatory acne lesions. RL-PDT benefits from milder adverse effects than those of BL-PDT.

[PMID: 38965092 DOI: 10.1007/s10103-024-04129-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2023] [Accepted: 06/26/2024] [Indexed: 07/06/2024]
Abstract
The study utilized 5-ALA-PDT to treat patients with CIN or VaIN and assessed their clinical response, HPV clearance, and influencing factors after photodynamic therapy (PDT). This study involved 56 patients who received 5-ALA-PDT in a single center from May 2020 to March 2022, including 12 patients with CIN, 30 patients with VaIN, and 14 patients with both CIN and VaIN. Follow-up were conducted within 6 and 12 months after treatment to evaluate the clinical effectiveness of PDT. The assessment criteria included histological response (ER, elimination rate, RR, regression rate) and HPV clearance. Additionally, factors that could potentially influence the outcomes were analyzed. After PDT, the histological response showed an ER of 48.2% (27/56) and a RR of 80.4% (45/56) within 6 months of follow-up. The elimination rate increased to 69.6% (39/56) within 12 months, along with a regression rate of 82.1% (46/56). The rates of HPV clearance were observed to be 37.5% (21/56) and 44.6% (25/56) within 6 and 12 months, respectively. The study also revealed that HPV clearance significantly influenced histologic elimination within 6 months (p < 0.001) and histologic regression within 12 months (p < 0.01). Furthermore, premenopausal women exhibited a higher HPV clearance rate compared to postmenopausal women (61.5% vs. 30.0%, p = 0.036). 5-ALA PDT can be considered as an available option for the treatment of lower genital squamous intraepithelial lesions. The efficacy of its histologic response depends on HPV clearance. Additionally, it has been found that premenopausal women may benefit more from this treatment.

Abstract
Perifolliculitis capitis abscedens et suffodiens, also known as dissecting cellulitis of the scalp, is a rare, chronic suppurative, inflammatory head hair follicle disease, which seriously affects the patient's quality of life. Clearly, clinical treatment varies widely and is somewhat challenging. We report a case of a 19-year-old male patient who had good results through surgery combined with photodynamic therapy. Surgery combined with photodynamic therapy for perifolliculitis capitis abscedens et suffodiens is effective and safe, especially for patients with poor responses to previous traditional treatments.

Abstract
Background: Photodynamic therapy (PDT) can be a promising alternative for patients with acne vulgaris. Our study aimed to evaluate the efficacy and safety of red light photodynamic therapy with BF-200 ALA gel in the treatment of different types of acne vulgaris. Methods: We performed a retrospective, observational study of a series of 22 cases. All patients were treated according to a mild PDT protocol. After a careful wash of the affected skin areas, BF-200 ALA gel was applied to the skin in a thin layer and incubated for 30 min, followed by illumination using narrow-spectrum red light (635 nm) at a dose of 4 J/cm2. Most patients received one (36.4%), two (27.3%), or three (22.7%) PDT sessions. About a third of the patients received concomitant acne treatment with topical retinoids. Results: Patients of 25.1 ± 8.9 years suffering from papulopustular (45.5%), nodular (27.3%), and comedonal acne (27.3%) in the face were included. Irrespective of acne type or severity, 95.5% of patients had good or excellent responses to the treatment with PDT (≥60% lesion clearance). We found no association between concomitant acne medication and the favorable results achieved by PDT. Most patients reported no adverse events (72.7%), except for six patients who experienced erythema. The good efficacy results were maintained over a follow-up period of 12.5 ± 10.8 months. Conclusions: In this study, we show that PDT with BF-200 ALA gel and low light dose is an effective and long-lasting option for the treatment of different acne types.

J Am Acad Dermatol 2023; 89:711-718. [PMID: 37356626 DOI: 10.1016/j.jaad.2023.06.027] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Revised: 05/23/2023] [Accepted: 06/01/2023] [Indexed: 06/27/2023]
Abstract
BACKGROUND 5-Aminolevulinic acid photodynamic therapy (ALA-PDT) showed potential to treat rosacea according to recent studies; however, a lack of clinical evidence and unclear adverse effects limit its use. OBJECTIVE To compare the effect of ALA-PDT vs minocycline on rosacea. METHODS In this single-center, randomized, evaluator-blind, controlled study, patients with moderate-to-severe rosacea were allocated to receive 3 to 5 sessions of ALA-PDT or 8 weeks of 100 mg daily minocycline treatment, followed by a 24-week follow-up. RESULTS Of all the 44 randomized patients, 41 received complete treatment (ALA-PDT: 20 and minocycline: 21 patients). At the end of treatment, ALA-PDT showed noninferior improvement of papulopustular lesions and Rosacea-specific Quality of Life compared with minocycline (median reduction of lesion count: 19 vs 22, median change of Rosacea-specific Quality of Life score: 0.48 vs 0.53). The Clinician's Erythema Assessment success of ALA-PDT was lower than that of minocycline's (35% vs 67%). Demodex density and relapse rate were comparable in both groups. Erythema, mild pain, and exudation were the most common adverse reactions of ALA-PDT. LIMITATIONS Limited sample size restricted us from drawing further conclusions. CONCLUSION As minocycline does, ALA-PDT can improve rosacea mainly in papulopustular lesions and patients' quality of life, indicating a new option for rosacea.

Abstract
BACKGROUND The aim of this study was to explore the anti-inflammatory and anti-lipid effects of lactoferrin on SZ95 human sebaceous gland cells and mouse model of acne. METHODS SZ95 cells were co-cultured with different concentrations of lactoferrin, and cell viability was determined using the 2,5-diphenyl-2H-tetrazolium bromide method. Oil red O and Nile red staining were performed to determine the lipid content. The mRNA expression of genes related to lipid metabolism (sterol regulatory element-binding protein-1 [SREBP-1], fatty acid synthase [FAS], stearoyl-CoA desaturase-1 [SCD-1], fatty acid desaturase 2 [FADS2]) and inflammation (interleukin-8 [IL-8]) was determined by reverse transcription-polymerase chain reaction. An acne mouse model was established using injection of P. acnes on the backs of mice. The proliferation and apoptosis of sebaceous gland cells were examined by immunohistochemistry against proliferating cell nuclear antigen (PCNA) and TUNEL staining, respectively. Western blotting was used to detect FADS2 and CXCL15 protein expression. RESULTS Lactoferrin treatment at 10-500 μg/ml significantly decreased the lipid content, as revealed by the oil red O and Nile red staining. It also attenuated the increase of mRNA expression of SREBP-1, FAS, SCD-1, FADS2, and IL-8 in insulin-treated SZ95 cells. Moreover, lactoferrin treatment at the doses of 1-50 mg/mouse significantly reduced the inflammation and lipid production in the mouse model of acne. Also, the number of sebaceous gland cells was significantly reduced, and apoptosis was significantly increased by lactoferrin treatment in the mice. Mechanically, the levels of FADS2 and CXCL15 proteins in tissues were significantly decreased after lactoferrin treatment in the model mice. CONCLUSION Our results demonstrate the potential of lactoferrin against sebogenesis, sebaceous gland inflammation in acne.

Abstract
BACKGROUND Acne is the eighth-most prevalent inflammatory skin disease with no optimal treatment. Photodynamic therapy (PDT) is an effective treatment for severe acne. AIMS The effect of PDT on the composition and diversity of skin microflora in severe acne patients was studied. MATERIALS AND METHODS A total of 18 patients with severe acne and 8 healthy individuals were selected for this study. Patients were treated with 5-aminolevulinic acid-mediated PDT once a week three times in total; the skin microbiome was measured by 16S ribosomal RNA gene sequencing before and after treatment (1 week after each PDT). RESULTS The microflora composition was different between healthy controls and patients, and between patients before and after treatment. Alpha diversity indices were lower in patients than those in control. There were 15 bacterial genera with high relative abundance that had noticeable changes during treatment. At the genus level,particularly Cutibacterium acnes (C. acnes formerly Propionibacterium acnes), there was no statistically significant difference among different group. The abundances of Staphylococcus epidermidis and Staphylococcus aureus were low. DISCUSSION The microbial composition is different between severe acne patients acne patients and healthy individuals. The therapeutic efficacy of severe acne treated with PDT is associated with the composition and diversity of skin microbiota. CONCLUSION The skin microbial composition changes after PDT treatment. PDT is an effective method for the treatment of severe acne.

Abstract
Cervical cancer ranks 4th place among malignant neoplasms in the world in 2020. HPV is the main reason for cervical cancer. The «Gold standard» of cervical screening is an «HPV-testing + PAP-test» co-test. The immune system can clear HPV infection. Pathway of cervical cancer development is investigated, but immunity recognition of HPV is still incompletely studied. Toll-like receptors (TLRs) are membrane receptors on the cell membranes and membrane organelles. TLRs ligands could be bacterial, viral pathogens or toxins. When a ligand binds to TLRs, cytokines production is triggered. Chronic inflammation process down-regulates TLRs expression. This helps develop HPV infection. The current paper demonstrates how photodynamic therapy induces TLRs gene expression. A personal approach to estimating photodynamic therapy by an innate immune response in a clinical case is described. A 43-year-old woman with high-grade squamous intraepithelial lesion and 33rd type of HPV infection turned into a private clinic. The patient had complex check-ups before we defined a treatment strategy. Photodynamic therapy was performed as a non-invasive fertility-preserving treatment. We tested TLRs 2/3/4/8 gene expression before and after photodynamic therapy in 2 hours, one week and 6-month periods. PDT induces TLRs gene expression in a 6-month period. HPV elimination was achieved. The patient has no atypical cells in liquid-based cytology investigation after PDT.

Abstract
BACKGROUND Condyloma acuminatum (CA) is a common sexually transmitted disease caused by human papillomaviruses. Five-aminolevulinic acid-photodynamic therapy (ALA-PDT) can promote the apoptosis of keratinocytes and inhibit proliferation; however, the effect of ALA-PDT on the immune mechanism of CA tissue is not well understood. In this study, we examined the changes in Toll-like receptor 4 (TRL4) and nuclear factor kappa B (NF-κB) expression in CA tissues before ALA-PDT treatment to determine its effects and possible immune mechanisms. METHODS Immunohistochemistry (streptavidin-peroxidase) was used to detect the expression of TLR4 and NF-κB in the keratinocytes of the patients with CA before and after ALA-PDT treatment. RESULTS Before treatment, the positive TLR4 and NF-κB expression rates in the keratinocytes of the patients with CA were 86.53% (45/52) and 94.23% (49/52), respectively, whereas after treatment, these rates were 44.230% (23/52) and 38.46% (20/52), respectively. Positive TLR4 and NF-κB expression in the keratinocytes of CA was mostly ++ to +++ in intensity before ALA-PDT and mostly ranged from - to + after treatment. The positive expression rate and intensity of TLR4 and NF-κB in the two groups before and after ALA-PDT were significantly different (P < 0.05). There was a positive correlation between the expression of TLR4 and NF-κB in the CA tissues after ALA-PDT (r = 0.486, P < 0.05). CONCLUSIONS ALA-PDT may relieve local immunosuppressive states by reducing TLR4 and NF-κB expression and jointly promoting CA regression, which is a potential molecular mechanism of ALA-PDT in CA treatment.

Abstract
Acne vulgaris (AV) is a chronic inflammatory disease of the pilosebaceous unit, and Propionibacterium acnes (P. acnes) has been implicated in acne inflammation. Numerous studies have shown that non-coding RNAs play important roles in regulating the pathophysiological processes of acne. In addition, the first imprinted long non-coding RNA (lncRNA) identified, H19, plays a critical role in inflammatory disease. However, the expression and role of H19 in AV remain unclear. In this study, we investigated the effects of H19 in keratinocytes and explored the regulatory mechanisms underlying these effects. H19 was upregulated in keratinocytes treated with P. acnes in a concentration-dependent manner. The phosphorylated forms of the nuclear factor (NF)-κB-related proteins IκBα (p-IκBα) and p65 (p-P65) were significantly upregulated after P. acnes treatment. Additionally, secretion of the proinflammatory cytokines tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-8 was upregulated in a concentration-dependent manner. Knockdown of H19 inhibited the expression of p-IκBα and p-P65 as well as the secretion of TNF-α, IL-6, and IL-8 in keratinocytes treated with P. acnes. Moreover, H19 was found to exert its proinflammatory effects by activating NF-κB. H19, which was localized mainly in the cytoplasm of keratinocytes, facilitated Toll-like receptor 2 (TLR2) expression by acting as a miR-196a sponge. H19 thus promoted the activation of NF-κB and the secretion of inflammatory cytokines through the miR-196a/TLR2 axis. These findings provide novel insight into the pathogenesis of AV.

Evidence of hypericin photoinactivation of E. faecalis: From planktonic culture to mammalian cells selectivity up to biofilm disruption. Photodiagnosis Photodyn Ther 2020; 31:101759. [PMID: 32380254 DOI: 10.1016/j.pdpdt.2020.101759] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2019] [Revised: 03/22/2020] [Accepted: 03/27/2020] [Indexed: 12/28/2022]
Abstract
Antimicrobial Photodynamic Therapy (aPDT) is an alternative for microbiological inactivation. The aPDT is a method that uses a photosensitizer (PS) excited by visible light at the appropriate wavelength and the molecular oxygen present in the tissues resulting in the production of reactive oxygen species, which causes oxidative damage to biological molecules. This study aimed to perform an in vitro experimental sequence for photoinactivation of E. faecalis using Hypericin (HY) from planktonic culture to selectivity assays using mammalian cells up to biofilm. The results show that E. faecalis rapidly absorb HY. The levels of inactivation of E. faecalis reached up to 99% in planktonic culture. Transmission and Scanning Electron Microscopy demonstrate the remarkable morphological alterations resulting from photooxidation being the loss of membrane integrity assessed by fluorescence microscopy combined with a LIVE/DEAD™ kit. HY did not present cytotoxicity to the fibroblasts cell at the used conditions proving to be a selective molecule. Finally, 60% of photoinactivation was observed in the biofilm of E. faecalis when subject to HY-aPDT. These outcomes show the advantages of sequential in vitro experiments besides showing that HY is a potential PS for clinical trials due to its selectivity and photodynamic effect. This study also draws attention to the benefits of using methodologies that can evidence the antimicrobial effect beyond the typical constellation of cell death.

Abstract
BACKGROUND Photodynamic therapy (PDT) with 5-aminolevulinic acid (ALA) has been described as an effective treatment for severe acne. However, very little evidence exists on the optimal concentration of ALA used in PDT for severe acne. OBJECTIVES To compare the efficacy and safety of PDT with 5% ALA vs 10% ALA in severe acne. METHODS Twenty-three patients with severe facial acne were randomly assigned to receive PDT with 5% ALA or 10% ALA on the left or right side of the face. Four PDT sessions were conducted with a light dose of 96 J/cm2 . The reduction rates of lesion counts between the two groups were compared at the week-4 and week-12 follow-up visits. Effective rate at the week-12 visit was the primary clinical outcome. Pain and other side effects were evaluated at each visit. RESULTS The decrease in inflammatory lesions in the 10% ALA group was greater than that in the 5% ALA group at both week-4 (79.2% vs 62.5%, P = 0.009) and week-12 follow-up visits (88.5% vs 78.3%, P = 0.018), while the decrease in noninflammatory lesion counts between the two groups was not statistically significant at each follow-up visit. The effective rate in the 10% ALA group was significantly higher than that in the 5% ALA group (95.7% vs 69.6%, P = 0.02). No significant difference was observed in pain scores between the two groups except in the first treatment session. CONCLUSIONS Photodynamic therapy using 10% ALA was more effective for severe acne than PDT using 5% ALA.

Abstract
Antibiotics and photodynamic therapy (PDT) are widely employed in curing acne. However, antibiotics as an effective treatment would lead to bacterial resistance and severe side effects. In this study, we aimed to develop a novel TBO hydrogel, which could prolong the retention time of photosensitizer (TBO) at the lesion site and improve therapeutic effect. In vitro antibacterial experiments (against Staphylococcus aureus and Escherichia coli), the response surface methodology was used to optimize the formulation of TBO hydrogel. The results indicated that the optimal formulation was 0.5% (v/v) carbomer, 0.01 mg/mL TBO, 0.5% (v/v) ethanol concentration, 0.5% (v/v) Tween 80, the mass ratio of NaOH to carbomer of 0.4 (w/w). The TBO hydrogel formulation showed the strong antibacterial activity for Propionibacterium acnes. The stability, pH, and antibacterial activity of TBO hydrogel did not significantly change under 4 °C, 25 °C, and 40 °C during 6-week storage. Furthermore, TBO combined with carbomer hydrogel showed the 51.28% (4 h) and 69.80% (24 h) release. In summary, the hydrogel TBO might be a vital therapeutic strategy to promote the PDT applied in the topical therapy of acne.

Abstract
BACKGROUND Rosacea is a common chronic cutaneous disorder which is characterized by flushing, erythema, papulopustules and telangiectasia. The pathogenesis of the disease is still unknown. A multifaceted approach is necessary to control the disease because of its tendency to relapse. New more effective treatment options are desirable to achieve a complete remission. Aminolevulinic acid-photodynamic therapy (ALA-PDT) is a well-established treatment for non-melanoma skin cancer and precancerous lesions. ALA- PDT can also be used for inflammatory disease, including acne vulgaris. However, little is known about the efficacy and safety of ALA-PDT for rosacea in Chinese patients with Fitzpatrick skin types III and IV. OBJECTIVES To investigate the efficacy and safety of ALA-PDT in the treatment of rosacea classified as erythematotelangiectatic type or papulopustular type. METHODS Twenty rosacea patients with either erythematotelangiectatic or papulopustular types were enrolled. 5% 5-Aminolevulinic acid in an oil-in-water emulsion was applied to the lesions under occlusion with plastic film for 2 h, and the lesions were irradiated with 100 mW/cm2, 80-90 J/cm2, LED red light (635 ± 15 nm) over 15 min in each session with four sessions at 10-day intervals. Objective measures (severity of flushing, erythema and telangiectasia, number of inflammatory lesions, VISIA Red Complexion Analysis images), subjective symptoms (including itching, prickling, burning, etc.) were recorded at baseline and at 4, 12 and 24 weeks after the last treatment. Adverse effects were recorded at each treatment and follow-up visit. RESULTS During the follow-up period, all patients showed gradual objective clinical improvement compared with baseline (P < 0.01). Clinical inflammatory lesions disappeared completely in all patients after 24 weeks. Subjective symptoms, including flushing, itching, prickling, burning et al, had vanished and did not show any relapse during the follow-up period. The main side effects of ALA-PDT were pain, erythema, swelling and post- inflammatory hyperpigmentation. All side-effects were transient and tolerated by all the patients. No patients were dissatisfied with the therapeutic outcome. CONCLUSIONS ALA-PDT is an effective and safe approach for the treatment of rosacea of erythematotelangiectatic or papulopustular types, to control clinical manifestations and reduce subjective symptoms.

Abstract
Antimicrobial Photodynamic Inactivation (a-PDI) is based on the oxidative destruction of biological molecules by reactive oxygen species generated by the photo-excitation of a photosensitive molecule. When a-PDT is performed with the use of mathematical models, the optimal conditions for maximum inactivation are found. Experimental designs allow a multivariate analysis of the experimental parameters. This is usually made using a univariate approach, which demands a large number of experiments, being time and money consuming. This paper presents the use of the response surface methodology for improving the search for the best conditions to reduce E. coli survival levels by a-PDT using methylene blue (MB) and toluidine blue (TB) as photosensitizers and white light. The goal was achieved by analyzing the effects and interactions of the three main parameters involved in the process: incubation time (IT), photosensitizer concentration (CPS), and light dose (LD). The optimization procedure began with a full 23 factorial design, followed by a central composite one, in which the optimal conditions were estimated. For MB, CPS was the most important parameter followed by LD and IT whereas, for TB, the main parameter was LD followed by CPS and IT. Using the estimated optimal conditions for inactivation, MB was able to inactivate 99.999999% CFU mL-1 of E. coli with IT of 28 min, LD of 31 J cm-2, and CPS of 32 μmol L-1, while TB required 18 min, 39 J cm-2, and 37 μmol L-1. The feasibility of using the response surface methodology with a-PDT was demonstrated, enabling enhanced photoinactivation efficiency and fast results with a minimal number of experiments.
