[PMID: 38760974 DOI: 10.1111/ijd.17194] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Revised: 03/27/2024] [Accepted: 03/29/2024] [Indexed: 05/20/2024]
Abstract
BACKGROUND Acne vulgaris is a chronic inflammatory dermatosis. Cutibacterium acnes plays a crucial role in the acne pathophysiology. Recent works present evidence of C. acnes growing as a biofilm in cutaneous follicles. This development is currently considered one of the leading causes of C. acnes in vivo persistence and resistance to antimicrobials used to treat acne. OBJECTIVE Our objective was to evaluate the effects of various active compounds (clindamycin, erythromycin, doxycycline, and myrtle extract) on eight distinct, well-characterized strains of C. acnes following their growth in biofilm mode. METHODS/RESULTS Cutibacterium acnes isolates from phylotypes IA1 and IA2 produce more biofilm than other phylotypes. No antibiotic effect was observed either during the curative test or preventive test. Myrtle extract at 0.01% (w/v) showed significant efficacy on the biofilm for C. acnes strains (curative assays). Furthermore, it appear that myrtle extract and doxycycline together reduce the overall biomass of the biofilm. A significant dose-dependent effect was observed during the preventive test, greater than the one observed under curative conditions, with an important loss of activity of the myrtle extract observed from 0.001% (w/v) concentration onwards. Transmission electron microscopy showed that bacteria treated with myrtle extract grew biofilms much less frequently than untreated bacteria. Additionally, when the quantity of myrtle extract grew, the overall number of bacteria dropped, indicating an additional antibacterial action. CONCLUSION These findings support the hypothesis that the different C. acnes phylotypes have various aptitudes in forming biofilms. They also suggest that myrtle extract is a promising alternative as an anti-biofilm and antibacterial agent in fighting diseases caused by planktonic and biofilm C. acnes.

Abstract
BACKGROUND Photodynamic therapy had made great progress in the treatment of acne vulgaris. However, there is no meta-analysis on the effectiveness and safety of red light therapy for acne vulgaris. OBJECTIVE To assess the efficiency and safety of red light therapy for acne vulgaris. METHODS PubMed, Cochrane Library, EMBASE, and Web of Science were retrieved to identify related studies. The outcomes were expressed as improvement in the average percentages of inflammatory acne lesions (MPRI) and non-inflammatory acne lesions (NMPRI), as well as the improvement of acne lesions respectively after treatment. RESULTS 13 randomized controlled trials (RCTs) consisting of 422 participants were included. There was no significant difference in the average number of non-inflammatory lesions (weighted mean difference (WMD = -0.527; 95% CI,-3.055~2.001; p = 0.683). Moreover, there was no statistically significant difference in the average number of inflammatory lesions (WMD =0.701; 95% CI, -0.809~2.212; p =0.363). In the subgroup analysis of the outcome changes in comedones, pustules, papules, and total lesions, it was found that red light therapy elicited no significant superiority compared with other conventional treatment methods (WMD = -1.125; 95% CI, -3.122~0.873; p = 0.270). Adverse events of the red light group were generally mild or even completely non-existent. CONCLUSION There was no statistically significant difference between red light therapy and traditional therapies in terms of efficacy. However, due to the heterogeneity of the researches and the lack of large sample size, the result of this study needs to be interpreted with caution.

Abstract
Acne vulgaris is a common, multifactorial, inflammatory skin disease affecting the pilosebaceous unit. Topical therapy is the first choice in the treatment of mild to moderate acne, and azelaic acid (AZA) is one of the most commonly used drugs. The aim of this study was to evaluate the safety and efficacy of a low-dose azelaic acid nanocrystal (AZA-NC) hydrogel in the treatment of mild to moderate facial acne. The study was designed as a double-blind, randomized controlled trial. Patients were randomized to treatment with AZA-NC hydrogel, 10%, or AZA cream, 20%, administered in quantities of approximately 1 g twice daily for 8 weeks. Efficacy of therapy was measured by the number of lesions and safety by the frequency and severity of adverse events. At week 8, the success rate of treatment with AZA-NC hydrogel, 10%, was 36.51% (p < 0.001) versus 30.37% (p < 0.001) with AZA cream. At week 8, treatment with AZA-NC hydrogel, 10%, resulted in a significant reduction in total inflammatory lesions from baseline of 39.15% (p < 0.001) versus 33.76% (p < 0.001) with AZA cream, and a reduction in non-inflammatory lesions from baseline of 34.58% (p < 0.001) versus 27.96% (p < 0.001) with AZA cream, respectively. The adverse event rate was low and mostly mild.

Abstract
BACKGROUND Acne is a common, economically burdensome condition that can cause psychological harm and, potentially, scarring. Topical benzoyl peroxide (BPO) is a widely used acne treatment; however, its efficacy and safety have not been clearly evaluated. OBJECTIVES To assess the effects of BPO for acne. SEARCH METHODS We searched the following databases up to February 2019: the Cochrane Skin Specialised Register, CENTRAL, MEDLINE, Embase, and LILACS. We also searched five trials registers and checked the reference lists of relevant randomised controlled trials (RCTs) and systematic reviews. SELECTION CRITERIA We included RCTs that compared topical BPO used alone (including different formulations and concentrations of BPO) or as part of combination treatment against placebo, no treatment, or other active topical medications for clinically diagnosed acne (used alone or in combination with other topical drugs not containing BPO) on the face or trunk. DATA COLLECTION AND ANALYSIS We used standard methodological procedures as expected by Cochrane. Primary outcome measures were 'participant global self-assessment of acne improvement' and 'withdrawal due to adverse events in the whole course of a trial'. 'Percentage of participants experiencing any adverse event in the whole course of a trial' was a key secondary outcome. MAIN RESULTS We included 120 trials (29,592 participants randomised in 116 trials; in four trials the number of randomised participants was unclear). Ninety-one studies included males and females. When reported, 72 trials included participants with mild to moderate acne, 26 included participants with severe acne, and the mean age of participants ranged from 18 to 30 years. Our included trials assessed BPO as monotherapy, as add-on treatment, or combined with other active treatments, as well as BPO of different concentrations and BPO delivered through different vehicles. Comparators included different concentrations or formulations of BPO, placebo, no treatment, or other active treatments given alone or combined. Treatment duration in 80 trials was longer than eight weeks and was only up to 12 weeks in 108 trials. Industry funded 50 trials; 63 trials did not report funding. We commonly found high or unclear risk of performance, detection, or attrition bias. Trial setting was under-reported but included hospitals, medical centres/departments, clinics, general practices, and student health centres. We reported on outcomes assessed at the end of treatment, and we classified treatment periods as short-term (two to four weeks), medium-term (five to eight weeks), or long-term (longer than eight weeks). For 'participant-reported acne improvement', BPO may be more effective than placebo or no treatment (risk ratio (RR) 1.27, 95% confidence interval (CI) 1.12 to 1.45; 3 RCTs; 2234 participants; treatment for 10 to 12 weeks; low-certainty evidence). Based on low-certainty evidence, there may be little to no difference between BPO and adapalene (RR 0.99, 95% CI 0.90 to 1.10; 5 RCTs; 1472 participants; treatment for 11 to 12 weeks) or between BPO and clindamycin (RR 0.95, 95% CI 0.68 to 1.34; 1 RCT; 240 participants; treatment for 10 weeks) (outcome not reported for BPO versus erythromycin or salicylic acid). For 'withdrawal due to adverse effects', risk of treatment discontinuation may be higher with BPO compared with placebo or no treatment (RR 2.13, 95% CI 1.55 to 2.93; 24 RCTs; 13,744 participants; treatment for 10 to 12 weeks; low-certainty evidence); the most common causes of withdrawal were erythema, pruritus, and skin burning. Only very low-certainty evidence was available for the following comparisons: BPO versus adapalene (RR 1.85, 95% CI 0.94 to 3.64; 11 RCTs; 3295 participants; treatment for 11 to 24 weeks; causes of withdrawal not clear), BPO versus clindamycin (RR 1.93, 95% CI 0.90 to 4.11; 8 RCTs; 3330 participants; treatment for 10 to 12 weeks; causes of withdrawal included local hypersensitivity, pruritus, erythema, face oedema, rash, and skin burning), erythromycin (RR 1.00, 95% CI 0.07 to 15.26; 1 RCT; 60 participants; treatment for 8 weeks; withdrawal due to dermatitis), and salicylic acid (no participants had adverse event-related withdrawal; 1 RCT; 59 participants; treatment for 12 weeks). There may be little to no difference between these groups in terms of withdrawal; however, we are unsure of the results because the evidence is of very low certainty. For 'proportion of participants experiencing any adverse event', very low-certainty evidence leaves us uncertain about whether BPO increased adverse events when compared with placebo or no treatment (RR 1.40, 95% CI 1.15 to 1.70; 21 RCTs; 11,028 participants; treatment for 10 to 12 weeks), with adapalene (RR 0.71, 95% CI 0.50 to 1.00; 7 RCTs; 2120 participants; treatment for 11 to 24 weeks), with erythromycin (no participants reported any adverse events; 1 RCT; 89 participants; treatment for 10 weeks), or with salicylic acid (RR 4.77, 95% CI 0.24 to 93.67; 1 RCT; 41 participants; treatment for 6 weeks). Moderate-certainty evidence shows that the risk of adverse events may be increased for BPO versus clindamycin (RR 1.24, 95% CI 0.97 to 1.58; 6 RCTs; 3018 participants; treatment for 10 to 12 weeks); however, the 95% CI indicates that BPO might make little to no difference. Most reported adverse events were mild to moderate, and local dryness, irritation, dermatitis, erythema, application site pain, and pruritus were the most common. AUTHORS' CONCLUSIONS Current evidence suggests that BPO as monotherapy or add-on treatment may be more effective than placebo or no treatment for improving acne, and there may be little to no difference between BPO and either adapalene or clindamycin. Our key efficacy evidence is based on participant self-assessment; trials of BPO versus erythromycin or salicylic acid did not report this outcome. For adverse effects, the evidence is very uncertain regarding BPO compared with adapalene, erythromycin, or salicylic acid. However, risk of treatment discontinuation may be higher with BPO compared with placebo or no treatment. Withdrawal may be linked to tolerability rather than to safety. Risk of mild to moderate adverse events may be higher with BPO compared with clindamycin. Further trials should assess the comparative effects of different preparations or concentrations of BPO and combination BPO versus monotherapy. These trials should fully assess and report adverse effects and patient-reported outcomes measured on a standardised scale.

Abstract
We developed an artificial intelligence algorithm (AIA) for smartphones to determine the severity of facial acne using the GEA scale and to identify different types of acne lesion (comedonal, inflammatory) and postinflammatory hyperpigmentation (PIHP) or residual hyperpigmentation. Overall, 5972 images (face, right and left profiles) obtained with smartphones (IOS and/or Android) from 1072 acne patients were collected. Three trained dermatologists assessed the acne severity for each patient. One acne severity grade per patient (grade given by the majority of the three dermatologists from the two sets of three images) was used to train the algorithm. Acne lesion identification was performed from a subgroup of 348 images using a tagging tool; tagged images served to train the algorithm. The algorithm evolved and was adjusted for sensibility, specificity and correlation using new images. The correlation between the GEA grade and the quantification and qualification of acne lesions both by the AIA and the experts for each image were evaluated for all AIA versions. At final version 6, the GEA grading provided by AIA reached 68% and was similar to that provided by the dermatologists. Between version 4 and version 6, AIA improved precision results multiplied by 1.5 for inflammatory lesions, 2.5 for non-inflammatory lesions and by 2 for PIHP; recall was improved by 2.6, 1.6 and 2.7. The weighted average of precision and recall or F1 score was 84% for inflammatory lesions, 61% for non-inflammatory lesions and 72% for PIHP.

Abstract
Background. According to European and RF clinical guidelines, only the systemic use of isotretinoin in severe acne has a high level of evidence. However, this therapy is frequently associated with the development of retinoid dermatitis, the prevention and correction of which requires the application of emollients. Aim. To evaluate the efficacy and tolerability of the Perfectoin cream during treatment and prevention of retinoid dermatitis in patients with severe acne receiving systemic treatment with isotretinoin.Materials and methods. Two groups of patients each comprising 38 people with moderate, severe and resistant to standard therapy forms of acne were observed. Each group included 22 patients with retinoic dermatitis manifestations and 16 without such symptoms. The patients in the main and comparison groups were prescribed the Perfectoin cream and the dexpanthenol cream, respectively. Control of the skin condition was performed prior to the study and following 1, 3 and 6 months of therapy. Assessment parameters were the main symptoms of retinoid dermatitis (erythema, lichenification, excoriation, itching, feeling of dryness/tightness of the skin), indicators of the hydration of the horny layer of the epidermis and the transepidermal loss of moisture, as well as the dermatology life quality index.Results. The study has shown that the Perfectoin cream in patients with acne receiving isotretinoin therapy helps to restore skin hydration and leads to a rapid regression of the main dermatological symptoms of retinoid dermatitis, thus improving the overall quality of patients’ life.

Abstract
INTRODUCTION Acne is a chronic disorder of the pilosebaceous unit affecting all ethnic groups. It remains in the top 5 skin conditions seen worldwide. The paucity of data characterizing acne in South African Blacks led us to the documentation of types and sequelae of acne. METHODS This is a cross- sectional study describing the spectrum and variants of acne in 5 tertiary hospitals in the second most populous province in South Africa over 3 months (January 1 - March 31, 2015). RESULTS Out of 3,814 patients seen in tertiary dermatology clinics, 382 (10%) had a primary diagnosis of acne or rosacea, forming the fourth most common condition seen. Acne accounted for 361 (94.5%); acne vulgaris was the commonest subtype at 273 (75.6%), followed by steroid-induced acne 46 (12.7%), middle-age acne 6 (1.7%), acne excoriée 2 (0.6%), and "undefined" 34 (9.4%). CONCLUSION The observation of steroid-induced acne as the second most common variant in Black patients underlines the need to enquire about steroid use and education about the complications of using steroid-containing skin-lightening creams. Treatment of postinflammatory hyperpigmentation should be part of the armamentarium for holistic acne treatment in Blacks, as it remains a major concern even after active acne has resolved.

Abstract
Background Acne is one of the most common skin diseases. It has significant effect on
self-image and negative impact on quality of life. Postinflammatory
hyperpigmentation is an acquired hypermelanosis that occurs after a skin
injury or cutaneous inflammation. It is common sequelae in acne
patients. Objectives This study aimed to investigate the psychosocial impact of acne and
postinflammatory hyperpigmentation among patients treated in a dermatology
outpatient clinic at the University of Miami Hospital. Methods The study had the participation of 50 patients with acne and postinflammatory
hyperpigmentation. All participants volunteered to complete an anonymous
questionnaire containing socio-demographical information, questions about
patient's attitudes toward postinflammatory hyperpigmentation caused by
acne, the Cardiff Acne Disability Index and the Dermatology Life Quality
Index. Results Postinflammatory hyperpigmentation was more predominant in the face. Makeup
was frequently used to conceal the imperfections and the majority of
patients felt embarrassed due to their condition. Interestingly, the
majority of our patients did not have their quality of life impacted for
acne and postinflammatory hyperpigmentation. Study limitations A limitation of the study was the relatively small sample size. For this
reason, the findings of the study should not be generalized to the broader
community. Conclusion The current medical literature has many studies analyzing the psychological
impact of acne. This study is the first study in the literature that
analyzed the psychosocial impact of acne and postinflammatory
hyperpigmentation caused by acne.

Abstract
BACKGROUND Isotretinoin is a systemic retinoid used to treat acne and it binds receptors which are the member of steroid-thyroid hormone superfamily. Certain types of retinoids may cause abnormalities in serum thyroid function tests (sTFTs) by suppressing thyroid stimulating hormone (TSH). However, it is uncertain whether systemic isotretinoin has any effect on sTFTs. OBJECTIVE The aim of the study was to find out if there is any alteration in sTFTs of patients with acne vulgaris treated with systemic isotretinoin. METHODS A total of 51 patients (male/female: 22/29) with severe acne vulgaris treated with a total dose of 120 mg/kg isotretinoin were included into the study prospectively. Serum free T3 (fT3), free T4 (fT4) and TSH levels were measured at baseline, 3rd and 6th months of treatment. RESULTS Mean serum TSH levels at baseline, 3rd and 6th months of treatment were 1.57 ± 0.67, 2.07 ± 0.88 and 2.25 ± 0.86 uIU/mL, respectively. Mean serum TSH levels increased significantly following isotretinoin therapy (p < 0.01, p = 0.007 and p < 0.01, respectively). Mean serum fT3 levels at baseline, 3rd and 6th months of treatment were 3.59 ± 0.57, 3.19 ± 0.45 and 3.09 ± 0.61 pmol/L, respectively. Mean serum fT4 levels at baseline, 3rd and 6th months of treatment were 1.21 ± 0.19, 1.09 ± 0.16 and 1.11 ± 0.19 pmol/L, respectively. Mean serum fT3 and fT4 levels decreased significantly at 3rd and 6th months compared to baseline levels (p < 0.01 and p < 0.01, p < 0.01 and p = 0.001, respectively). CONCLUSION Systemic isotretinoin therapy causes significant alterations in sTFTs. Dose dependent or long-term effects of systemic isotretinoin on sTFTs needs further evaluation.

Abstract
Acne is a common inflammatory disease. Scarring is an unwanted end point of acne. Both atrophic and hypertrophic scar types occur. Soft-tissue augmentation aims to improve atrophic scars. In this review, we will focus on the use of dermal fillers for acne scar improvement. Therefore, various filler types are characterized, and available data on their use in acne scar improvement are analyzed.

Abstract
BACKGROUND Acne is a common disease in adolescents, but there are no epidemiological
data for acne in Brazil. OBJECTIVES To estimate the prevalence and degree of acne in adolescents from Sao Paulo
and study socio-demographic factors, family history and lifestyle,
associated with the disease. METHODS Cross-sectional study with 452 adolescents aged between 10 and 17 (mean=13.3
years), students from elementary and high school, examined by 3 independent
evaluators. RESULTS 62.4% were female, 85.8% white and 6.4% were aged 14. The prevalence was
96.0% and increased with age - all students over 14 had acne. The most
prevalent form of acne was comedonal (61.1%), followed by mild (30.6%) and
moderate (7.6%) papular-pustular, which affected mostly the face (97.5%).
About half of the adolescents reported family history for acne in mother or
father, and 20.6% reported previous treatment for acne. There was a higher
chance of presenting non-comedonal acne with increased age (p<0.001). DISCUSSION The prevalence of acne in adolescents varies widely due to the clinical
features and diagnostic methods used. Adolescents whose brothers/sisters had
acne (OR=1.7-p=0.027) and those over 13 (OR=8.3-p<0.001), were more
likely to have non-comedonal acne. CONCLUSION This study showed high prevalence of acne in adolescents from Sao Paulo,
predominantly the comedonal form on the face, with a higher chance of
presenting non-comedonal acne with increased age.

Abstract
There is a high unmet clinical need for new and better treatments in acne vulgaris. Propionibacterium acnes has a strong proinflammatory activity and targets molecules involved in the innate cutaneous immunity, keratinocytes and sebaceous glands of the pilosebaceous follicle. The role of P. acnes in acne confers legitimacy on the possible benefits of immunization-based approaches, which may represent a solution for limiting the development of antibiotic-resistant P. acnes. Various immunization-based approaches have been developed over the last decades, including killed pathogen-based vaccines, vaccination against cell wall-anchored sialidase, monoclonal antibodies to the Christie, Atkins, Munch-Peterson factor of P. acnes, anti-Toll-like receptors vaccines and natural antimicrobial peptides. This review summarizes the current evidence and explores the challenges to making this a realistic treatment option for the future.

Abstract
Acne in the adult female often presents as a chronic condition that can have a considerable negative psychological, social and emotional impact on the affected individual. Estimated prevalence rates of adult female acne vary widely according to study type. Case reports and clinical examinations estimate the prevalence of clinical acne at 10-12%, while survey estimates of physiological disease states are as high as 54%. Two subtypes of adult female acne may be defined according to time of onset: 'persistent' and 'late-onset', accounting for approximately 80 and 20% of cases, respectively. Postadolescent acne is generally mild-to-moderate in severity and presents with more inflammatory lesions and fewer comedones compared to adolescent acne. Furthermore, the impact of acne on the quality of life is often greater in adult females than in younger individuals. Despite these important differences, the key principles of acne treatment in the adult female do not differ significantly from those of other age groups. However, specific characteristics relating to the adult female should be considered when selecting a treatment regimen.

Abstract
The multifactorial etiology of acne vulgaris makes it challenging to treat. Current treatments include topical retinoids, benzoyl peroxide, topical and systemic antibiotics, azelaic acid, and systemic isotretinoin. Adjunctive and/or emerging approaches include topical dapsone, taurine bromamine, resveratrol, chemical peels, optical treatments, as well as complementary and alternative medications. The purpose of this paper is to discuss the therapies available for acne and their latest developments, including new treatment strategies (i.e. re-evaluation of the use of oral antibiotics and avoidance of topical antibiotic monotherapy, use of subantimicrobial antibiotic dosing, use of low-dose isotretinoin, optical treatments), new formulations (microsponges, liposomes, nanoemulsions, aerosol foams), new combinations (fixed-combination products of topical retinoids and topical antibiotics [essentially clindamycin] or benzoyl peroxide), new agents (topical dapsone, taurine bromamine, resveratrol) and their rationale and likely place in treatment. Acne vaccines, topical natural antimicrobial peptides, and lauric acid represent other promising therapies.

Abstract
Oral isotretinoin (13-cis retinoic acid) is the most effective drug in the treatment of acne and restores all major pathogenetic factors of acne vulgaris. isotretinoin is regarded as a prodrug which after isomerizisation to all-trans-retinoic acid (ATRA) induces apoptosis in cells cultured from human sebaceous glands, meibomian glands, neuroblastoma cells, hypothalamic cells, hippocampus cells, Dalton's lymphoma ascites cells, B16F-10 melanoma cells, and neuronal crest cells and others. By means of translational research this paper provides substantial indirect evidence for isotretinoin's mode of action by upregulation of forkhead box class O (FoxO) transcription factors. FoxOs play a pivotal role in the regulation of androgen receptor transactivation, insulin/insulin like growth factor-1 (IGF-1)-signaling, peroxisome proliferator-activated receptor-γ (PPArγ)- and liver X receptor-α (LXrα)-mediated lipogenesis, β-catenin signaling, cell proliferation, apoptosis, reactive oxygene homeostasis, innate and acquired immunity, stem cell homeostasis, as well as anti-cancer effects. An accumulating body of evidence suggests that the therapeutic, adverse, teratogenic and chemopreventive effecs of isotretinoin are all mediated by upregulation of FoxO-mediated gene transcription. These FoxO-driven transcriptional changes of the second response of retinoic acid receptor (RAR)-mediated signaling counterbalance gene expression of acne due to increased growth factor signaling with downregulated nuclear FoxO proteins. The proposed isotretinoin→ATRA→RAR→FoxO interaction offers intriguing new insights into the mode of isotretinoin action and explains most therapeutic, adverse and teratogenic effects of isotretinoin in the treatment of acne by a common mode of FoxO-mediated transcriptional regulation.
