Project description:INTRODUCTION:Scarring is an unfortunate clinical outcome of acne. Current treatment options for atrophic acne scars are dominated by non-pharmacological, invasive procedures which may not be suitable or affordable to all patients. This phase II, single-center, open-label, exploratory study assessed the efficacy, safety and subject-reported outcomes of adapalene 0.3% gel in the treatment of atrophic acne scars. METHODS:The study included subjects aged 18-50 years with past history of acne and moderate to severe facial atrophic acne scars. Subjects received adapalene 0.3% gel once daily for the first 4 weeks and twice daily for the following 20 weeks. Assessments were performed at baseline, day 10 and weeks 4, 8, 16 and 24, and at post-treatment follow-ups (weeks 36 and 48-72). RESULTS:At week 24, investigator and subject assessments reported improvement in skin texture/atrophic scars in 50% and > 80% of subjects, respectively. Subjects were satisfied with the treatment and reported improvements in quality of life. CONCLUSION:Daily use of adapalene 0.3% gel for the treatment of atrophic acne scars showed promising clinical efficacy, a favorable tolerability profile, and improvement in quality of life.

Project description:IntroductionAtrophic scarring occurs throughout the course of inflammatory acne and across the spectrum of severity. This study evaluates perceptions of the general population toward individuals with clear skin and acne scars.MethodsAn online survey administered in the USA, UK, Japan, Germany, France and Brazil to respondents 18 years and over presented three facial pictures of clear skin or digitally superimposed acne scars (but no active acne lesions) in a random fashion. At least one clear and one scar picture were presented to each participant.ResultsAmong the 4618 responders, 33% themselves had facial acne scars. The skin was the first thing noticed about the face by 41% when viewing pictures with scars vs 8% viewing clear skin (p < 0.05). Those with scars were less likely to be considered attractive (17% vs 25%), confident (25% vs 33%), happy (23% vs 30%), healthy (21% vs 31%) and successful (17% vs 24%), and more likely to be perceived as insecure (15% vs 8%) and shy (23% vs 14%) compared with those with clear skin (all p < 0.05). The significance of the responses obtained varied according to the acne and scar status of the respondent. Skin care was cited as the habit most in need of improvement by 59% vs 13% of respondents viewing pictures with scars vs clear skin, respectively (p < 0.05). All respondent subgroups cited skin care irrespective of their own acne and scar status (all p < 0.05 vs pictures with clear skin). Those with scars were thought less likely to have a promising future (78% vs 84%) than those with clear skin (p < 0.05). The majority of respondents reported willingness to pay money to eradicate scars.ConclusionThe results of this multi-national survey demonstrate that facial acne scars are perceived negatively by society, confirming the importance of preventing acne scars with early treatment of inflammatory acne.FundingGalderma International S.A.S France.

Project description:BackgroundAcne affects more than 80% of adolescents and young adults, who most often develop acne scars. Supporting data on the effect of acne scars on patient's health-related quality of life (HRQOL) are limited.ObjectiveThe aim was to determine how the severity of acne scars impacts the HRQOL of afflicted individuals.MethodsIn this population-based cross-sectional study, 723 adults with facial acne scars but without active acne lesions self-completed the Self-assessment of Clinical Acne-Related Scars (SCARS) questionnaire formulated to investigate degree of acne scarring. The Facial Acne Scar Quality of Life (FASQoL), Dermatology Life Quality Index (DLQI), and Dysmorphic Concern Questionnaire (DCQ) were completed to assess the attitude of these patients toward their scars and the impact of scarring on their HRQOL.ResultsThe mean (standard error) DLQI score for facial acne scars was 6.26 (0.22). Acne scars were considered a 'very large' or 'extremely large' concern by 19.3% of participants with mild scars as compared to 20.1% and 34.0% of participants with moderate and severe/very severe scars, respectively (P = 0.003). Higher FASQoL scores were associated with increased severity of scarring (P = 0.001). In total, 16.9% of participants had clinical features of dysmorphia (i.e., DCQ > 13). DCQ scores were significantly higher among participants with more severe scarring (mean DCQ score of 8.04 [0.28], 8.40 [0.18], and 10.13 [0.08] among participants with mild, moderate, and severe/very severe acne scars, respectively; P = 0.001). Most commonly reported signs of emotional distress were self-consciousness (68.0%) and worry about scars not going away (74.8%).ConclusionsThis study highlights the significant psychosocial impact of atrophic acne scars in the form of embarrassment and self-consciousness. Individuals with mild scars also expressed significant impact on quality of life that increased with aggravation of scar severity. Patient-reported outcomes provide an insight into the physical, functional, and psychological impact of acne scarring from the patient's perspective.

Project description:Background: Acne-induced scarring is associated with a similar burden as acne, i.e. diminished quality of life, and may be avoided if patients receive appropriate and timely acne treatment. In 2017, a four item-Acne-Scar Risk Assessment Tool (4-ASRAT) was designed by Tan et al. to categorise patients with acne into lower-risk or higher-risk for acne scarring. Its applicability outside the initial study population (France, Brazil and United States) remains to be determined. Methods: A study protocol was developed to create a systematic approach for validating and adapting 4-ASRAT to different populations, Ecuador in this case. The protocol was reviewed by 11 local and international dermatologists and pilot-tested in an Ecuadorian population using a sample of 10 participants who currently had or had had acne. Feedback from the pilot study was used to improve the study protocol. The results of the pilot study are included here, and the final study protocol is available as extended data. Results: The protocol proved to be applicable. Images taken of participants were a valuable resource for dermatological evaluation about the presence or absence of acne scars. Tangential light is necessary for this evaluation. Although dermatological assessments varied, we concluded that assessment by three local dermatologists for each participant was adequate for reaching a consensus on the presence or absence of acne scars. Conclusions: Considering the morbidity related to acne and acne scars, tools designed as prevention that alert patients about risk of developing scarring are necessary. The proposed protocol shows a feasible way of validating and adapting 4-ASRAT to different populations.

Project description:IntroductionAcne scarring is a common undesirable complication of acne vulgaris. Fractional erbium-yttrium aluminum garnet (YAG) 2940 nm laser and platelet-rich plasma have been used in treating acne scars with variable outcomes. The objective of this study is to assess the efficacy of fractional erbium-YAG 2940 nm laser and platelet-rich plasma as a single line of treatment in comparison with combined treatment in atrophic postacne scars.MethodsSeventy-five patients were included in this trial and randomized into three equal groups (25 each). Group A was subjected to six sessions of erbium-YAG laser for 6 months, group B was treated with 12 sessions of platelet-rich plasma over the same period, and group C was subjected to six sessions of erbium-YAG laser plus 12 sessions of platelet-rich plasma over the same period. Each subject was evaluated by acne scar grading, photography, and subjective evaluation.ResultsBoth treatment modalities showed improvement of acne scars, but the improvement with combined treatment was better than that with erbium-YAG laser or platelet-rich plasma alone regarding scar grade improvement (P = 0.007 and 0.001), clinical improvement (P = 0.001 and 0.001), and patient satisfaction (P = 0.005 and 0.001), respectively.ConclusionsThe combination of platelet-rich plasma plus erbium-YAG laser is superior to either treatment alone for acne scars, with trivial side effects for all treatment modalities.Trial registrationClinicalTrials.gov identifier; NCT03933033.

Project description:BackgroundFractional picosecond lasers is effective for the treatment of wrinkles or acne scars.ObjectiveTo investigate the safety and efficacy of treatment with a fractional 1,064-nm picosecond laser with a diffractive optic element for facial wrinkles and acne scars.MethodsThis prospective open-labeled trial comprised 22 subjects with facial wrinkles or acne scars. Subjects received three laser treatments with a fractional 1,064-nm picosecond laser at 3-week intervals. The efficacy and safety were evaluated at every visit and 2 months after the final treatment (14 weeks from the first treatment session). Global photographic assessments were performed by three blinded dermatologists and the subjects. Skin profilometry was performed using three-dimensional digital photographs; viscoelasticity was measured.ResultsThe overall mean global improvement scores assessed by the dermatologists at weeks 3, 6, and 14, were 1.8±1.46, 2.5±1.88, and 3.5±1.84, respectively, and those assessed by the subjects were 2.7±2.08, 4.1±2.24, and 5.0±2.52, respectively. Skin profilometry showed significant improvements in the skin wrinkles, texture, depressions, and pores. The gross elasticity and skin firmness significantly improved by 10.96% and 9.04%, respectively. The major adverse reactions were erythema, pruritus, and petechiae, which disappeared within 2~3 days.ConclusionThe fractional 1,064-nm picosecond laser is an effective and safe therapeutic modality for skin rejuvenation.

Project description:BackgroundVery few clinical trials have investigated the effect of topical acne treatment on scarring.ObjectivesOur objective was to evaluate the efficacy of adapalene 0.3%/benzoyl peroxide 2.5% gel (A0.3/BPO2.5) in atrophic acne scar formation in patients with acne.MethodsIn this multicenter, randomized, investigator-blinded, vehicle-controlled study, subjects with moderate or severe facial acne (Investigator's Global Assessment [IGA] score 3 or 4; ≥ 25 inflammatory lesions; ten or more atrophic acne scars) applied A0.3/BPO2.5 or vehicle daily per half face for 24 weeks. Subjects with acne requiring systemic treatment were excluded. Assessments included investigator atrophic acne scar count, Scar Global Assessment (SGA), acne lesion count, IGA, skin roughness and skin texture, subject self-assessment of clinical acne-related scars and satisfaction questionnaire, tolerability, and safety.ResultsIncluded subjects (n = 67) had mainly moderate acne (92.5% IGA 3); mean scores at baseline were approximately 40 acne lesions and 12 scars per half face. By week 24, the change from baseline in total scar count was - 15.5% for A0.3/BPO2.5 versus + 14.4% for vehicle (approximately 30% difference), with a mean of 9.5 scars versus 13.3 per half face, respectively (p < 0.0001). For SGA at week 24, a total of 32.9% with A0.3/BPO2.5 versus 16.4% with vehicle (p < 0.01) were clear/almost clear. Inflammatory acne lesions decreased by 86.7% for A0.3/BPO2.5 versus 57.9% for vehicle (p < 0.0001), and 64.2 versus 19.4% of subjects, respectively, were IGA clear/almost clear (p < 0.0001) at week 24. Treatment-related AEs were reported by 20.9% for A0.3/BPO2.5 versus 9% for vehicle side, most commonly skin irritation (14.9 vs. 6%, respectively).ConclusionsTopical A0.3/BPO2.5 prevented and reduced atrophic scar formation. Scar count increased with vehicle (+ 14.4%) but decreased with A0.3/BPO2.5 (- 15.5%) over 24 weeks.Trial registryClinicalTrials.gov identifier NCT02735421.

Project description:Acne has several effects on physical symptoms, but the main impacts are on the quality of life, which can be improved by treatment. There are several acne treatments but less evidence comparing their relative efficacy. Thus, we assessed the comparative efficacy of pharmacological and nonpharmacological interventions for acne. We searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials from inception to April 2019, to include randomized controlled trials for acne that compared topical antibiotics (TA), benzoyl peroxide (BPO), topical retinoids (TR), oral antibiotics (OA), lasers, light devices including LED device (LED), photodynamic therapy (PDT), and intense pulsed light, chemical peels (CP), miscellaneous therapies or complementary and alternative medicine (MTCAM), or their combinations. We performed Bayesian network meta-analysis with random effects for all treatments compared with placebo and each other. Mean differences (MDs) of lesions count and risk ratios of adverse events with their 95% credible intervals (CrIs) were calculated, and all interventions were ranked by the Surface Under the Cumulative Ranking (SUCRA) values. Additional frequentist additive network meta-analysis was performed to detect the robustness of results and potential interaction effects. Sensitivity analyses were carried out with different priors, and metaregression was to adjust for nine potential effect modifiers. In the result, seventy-three randomized controlled trials (27,745 patients with mild to moderate acne), comparing 30 grouped intervention categories, were included with low to moderate risk of bias. For adverse effects, OA had more risk in combination treatment with others. For noninflammatory lesions reduction, seventeen interventions had significant differences comparing with placebo and three interventions (TR+BPO: MD = -21.89, 95%CrI [-28.97, -14.76]; TR+BPO+MTCAM: -22.48 [-34.13, -10.70]; TA+BPO+CP: -20.63 [-33.97, -7.13]) were superior to others with 94, 94, and 91% SUCRA values, respectively. For inflammatory lesions reduction, nineteen interventions were significantly better than placebo, and three interventions (TR+BPO: MD = -12.13, 95%CrI [-18.41, -5.80]; TR+BPO+MTCAM: -13.21 [-.39, -3.04]; LED: -11.30 [-18.34, -4.42]) were superior to others (SUCRA: 81, 81, and 77%, respectively). In summary of noninflammatory and inflammatory lesions results, TR+BPO and TA+BPO were the best options compared to others. The frequentist model showed similar results as above. In summary, current evidence supports the suggestion that TR+BPO and TA+BPO are the best options for mild to moderate acne. LED is another option for inflammatory lesions when drug resistance occurs. All the combinations involved with OA showed more risk of adverse events than others. However, the evidence of this study should be cautiously used due to the limitations.

Project description:The pathogenesis of acne has been linked to multiple factors such as increased sebum production, inflammation, follicular hyperkeratinization, and the action of Propionibacterium acnes within the follicle. In an attempt to understand the specific genes involved in inflammatory acne, we performed gene expression profiling in acne patients. Skin biopsies were obtained from an inflammatory papule and from normal skin in six patients with acne. Biopsies were also taken from normal skin of six subjects without acne. Gene array expression profiling was conducted using Affymetrix HG-U133A 2.0 arrays comparing lesional to nonlesional skin in acne patients and comparing nonlesional skin from acne patients to skin from normal subjects. Within the acne patients, 211 genes are upregulated in lesional skin compared to nonlesional skin. A significant proportion of these genes are involved in pathways that regulate inflammation and extracellular matrix remodeling, and they include matrix metalloproteinases 1 and 3, IL-8, human beta-defensin 4, and granzyme B. These data indicate a prominent role of matrix metalloproteinases, inflammatory cytokines, and antimicrobial peptides in acne lesions. These studies are the first describing the comprehensive changes in gene expression in inflammatory acne lesions and are valuable in identifying potential therapeutic targets in inflammatory acne. Experiment Overall Design: total 18 chips. 6 for acne lesion samples, 6 for normal skin samples, 6 for non-acne patient normal skin samples
