An Bras Dermatol 2018; 92:350-355. [PMID: 29186247 PMCID: PMC5514575 DOI: 10.1590/abd1806-4841.20175543] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2016] [Accepted: 05/03/2016] [Indexed: 11/22/2022] Open
Abstract
Background Photodynamic therapy with topical aminolevulinic acid (ALA-PDT) has been
suggested to be effective in treatment of acne vulgaris. However, adverse
events occur during and after treatment. Objectives To compare the efficacy and tolerability of optical intra-tissue fiber
irradiation (OFI) ALA-PDT versus traditional ALA-PDT in treatment of acne
vulgaris in rabbit models. Methods Twenty-five rabbits of clean grade were used. Twenty rabbits were randomly
selected to establish acne model and the other five were used as control.
Rabbits in model group (40 ears) were further divided into four groups (10
ears/group): I, OFI-ALA-PDT with the head of optical fiber inserted into the
target lesion (intra-tissue); II, traditional ALA-PDT group; III, OFI group;
IV, blank control group without any treatment. Uncomfortable symptoms,
adverse events, and effectiveness rates were recorded on post-treatment day
14, 30, and 45. Results On post-treatment day 14, the effectiveness rate in OFI-ALA-PDT group was
obviously higher than that of the other three groups (P<0.05). However,
no improved effects were observed in OFI-ALA-PDT group on day 30 and 45.
During the period of treatment, the frequencies of uncomfortable symptoms in
ALA-PDT group were obviously higher than those in the other three groups
(P<0.05). The adverse event rate in OFI-ALA-PDT group was obviously lower
than that of the ALA-PDT group (P<0.05). Study limitations The unblindness of the study and temporary animal models of acne induced may
hamper the assessment and monitoring of the results, and future studies are
still needed to clarify it further. Conclusion The OFI-ALA-PDT group (intra-tissue irradiation) showed no improved efficacy
on treating rabbit ear acne but had higher safety and better
tolerability.

Abstract
The objective of this article is to investigate the effectiveness and safety of photodynamic therapy (PDT) with 3.6 % topical aminolevulinic acid (ALA) and a short incubation time with red light in moderate to severe acne. One hundred and thirty-six patients with moderate to severe acne were treated with 3.6 % topical ALA-PDT for three sessions with an interval of 2 weeks. Patients were evaluated for efficacy and safety on week 2, 4, 6, 8, and 12 after the initial treatment. Most patients showed apparent clearance of acne lesions at the treated site after three sessions. The effective treatment rates were increased after the multiple therapies. The clinical outcomes are the best at 4 weeks after the final treatment. The total effectiveness rate and cure rate of the low-dose ALA-PDT procedure is 92.65 and 47.06 %, respectively. Thirty-one patients and nineteen patients showed apparent exacerbation of acne lesions before the 2nd and 3rd treatment, respectively, but all of them showed good or excellent improvement after a three-course treatment. A few patients showed mild relapse including papules and comedos at 8 weeks after the final treatment. No significant differences are found in the effects of different acne severity and different genders. Adverse reactions are mild and transient. A 3.6 % topical ALA-PDT with a short time incubation with red light is a simple and an effective treatment option for moderate to severe acne with mild side effects in Chinese people.

Abstract
Background To treat moderate to severe acne vulgaris, we developed an optical fiber imported intra-tissue photodynamic therapy: the optical fiber irradiation 5-aminolevulinic acid photodynamic therapy (OFI-ALA-PDT). The aim of this study was to compare the treatment effect and tolerability of OFI-ALA-PDT versus traditional ALA-PDT in the treatment of moderate to severe acne vulgaris. Material/Methods 60 patients with facial acne enrolled into this study were randomly divided into an OFI-ALA-PDT group and a traditional ALA-PDT group, with 30 patients in each group. The difference between these 2 groups was the red light irradiation methods used. In the OFI-ALA-PDT group we used intra-tissue irradiation (import the red light directly into the target lesion with optical fiber) for 5 min, while the traditional ALA-PDT group received whole-face irradiation for 20 min. All patients received 1 irradiation every 7 to 10 days for a total of 6 irradiations. Treatment effects and adverse reactions were recorded after the 4th and 6th irradiation, and at 4, 8, 16 weeks after the entire treatment. Results After the 4th irradiation, significantly different effective rates were observed in these groups (90.0% for the OFI-ALA-PDT group and 66.7% for the control group). However, no significant difference in effective rate was recorded in the later observations. There were 182 adverse reactions in the OFI-ALA-PDT group and 497 in the control group, which showed a significant difference (P<0.05). Conclusions OFI-ALA-PDT showed improved treatment effective rate in the early stage of irradiation, and it had fewer adverse reactions.

Abstract
BACKGROUND Topical photodynamic therapy (PDT) mediated with 5-aminolevulinic acid (ALA) offers an alternative option for the treatment of acne vulgaris. OBJECTIVE To study the effects of ALA dose, incubation time, and lesion type on protoporphyrin IX (PpIX) production and treatment outcomes. METHODS To examine the time course of PpIX production, 10% ALA was applied to inflammatory papules for 1 to 5 hours and followed by in situ fluorescence examination. To determine the effects of ALA dose and lesion type, 3, 5, and 10% ALA was applied to acne lesions in split-face fashion for 3 hours followed by whole-face light irradiation at 633 nm and 30 to 70 J/cm2. Treatment was repeated twice at 2-week intervals. RESULTS PpIX reached a stable level after 3 hours of incubation. Similar PpIX levels were seen in areas receiving 3, 5, and 10% ALA. Poisson regression analyses indicated that lesion counts decreased by 0.791 times for a one-unit increase in treatment times (95% CI 0.782-0.799 < .0001) but only by 0.999 times for a one-unit increase in ALA dose (95% CI 0.998-1.000 = .22). CONCLUSION The combination of low-dose ALA and a red light is a safe and effective option for the treatment of moderate to severe acne.

Abstract
The purpose of this study was to investigate the efficacy of phototherapy with a newly-developed 1450-nm diode laser in patients with mild to moderate acne. An open study was performed in acne patients who were treated up to five times with a two week interval. Acne lesions were reduced by 63%. Only one patient discontinued treatment due to vesicle formation as an adverse effect. Phototherapy using this diode laser source was effective and well tolerated in acne patients, suggesting that this phototherapy may be a new modality for the treatment of acne.

Abstract
Label-free chemical contrast is highly desirable in biomedical imaging. Spontaneous Raman microscopy provides specific vibrational signatures of chemical bonds, but is often hindered by low sensitivity. Here we report a three-dimensional multiphoton vibrational imaging technique based on stimulated Raman scattering (SRS). The sensitivity of SRS imaging is significantly greater than that of spontaneous Raman microscopy, which is achieved by implementing high-frequency (megahertz) phase-sensitive detection. SRS microscopy has a major advantage over previous coherent Raman techniques in that it offers background-free and readily interpretable chemical contrast. We show a variety of biomedical applications, such as differentiating distributions of omega-3 fatty acids and saturated lipids in living cells, imaging of brain and skin tissues based on intrinsic lipid contrast, and monitoring drug delivery through the epidermis.

Abstract
The polymorphic nature of the cytochrome P450 (CYP) genes affects individual drug response and adverse reactions to a great extent. This variation includes copy number variants (CNV), missense mutations, insertions and deletions, and mutations affecting gene expression and activity of mainly CYP2A6, CYP2B6, CYP2C9, CYP2C19 and CYP2D6, which have been extensively studied and well characterized. CYP1A2 and CYP3A4 expression varies significantly, and the cause has been suggested to be mainly of genetic origin but the exact molecular basis remains unknown. We present a review of the major polymorphic CYP alleles and conclude that this variability is of greatest importance for treatment with several antidepressants, antipsychotics, antiulcer drugs, anti-HIV drugs, anticoagulants, antidiabetics and the anticancer drug tamoxifen. We also present tables illustrating the relative importance of specific common CYP alleles for the extent of enzyme functionality. The field of pharmacoepigenetics has just opened, and we present recent examples wherein gene methylation influences the expression of CYP. In addition microRNA (miRNA) regulation of P450 has been described. Furthermore, this review updates the field with respect to regulatory initiatives and experience of predictive pharmacogenetic investigations in the clinics. It is concluded that the pharmacogenetic knowledge regarding CYP polymorphism now developed to a stage where it can be implemented in drug development and in clinical routine for specific drug treatments, thereby improving the drug response and reducing costs for drug treatment.

Abstract
BACKGROUND Recently, a demand for safe and effective treatment of acne has been increasing. Although visible light has attracted attention as a new option, the effect of red light alone has not yet been evaluated. OBJECTIVES The objective was to assess the efficacy of red light phototherapy with a portable device in acne vulgaris. METHODS Twenty-eight volunteers with mild to moderate acne were treated with portable red light-emitting devices in this split-face randomized trial. The right or left side of the face was randomized to treatment side and phototherapy was performed for 15 minutes twice a day for 8 weeks. Clinical photographs, lesion counts, and a visual analog scale (VAS) were used to assess each side of the face at baseline and Weeks 1, 2, 4, and 8, and a split-face comparison was performed. RESULTS The percent improvement in noninflammatory and inflammatory lesion counts of the treated side was significant compared to the control side (p<.005). VAS decreased from 3.9 to 1.9 on the treatment side and the difference between the treatment and control sides was significant at Week 8 (p<.005). CONCLUSIONS This study shows that red light phototherapy alone can be a new therapeutic option for acne vulgaris.
