A review of diagnosis and treatment of acne in adult female patients

Comprehensive transition of care for polycystic ovary syndrome from adolescence to adulthood

Polycystic ovary syndrome (PCOS) is a lifelong chronic condition that affects one in ten females and can be diagnosed in adolescence. As adolescents with PCOS transition to adulthood, counselling for lifestyle management and mental health concerns often transition from involving the family unit to increasingly individual-focused approaches. PCOS is associated with a large range of comorbidities affecting reproductive, metabolic, dermatological, and psychological health. The diagnosis and comorbidities of PCOS are influenced by pubertal hormones and need to be reassessed continuously to ensure that treatment remains appropriate for age and development. As young patients grow up, personal concerns often change, especially in relation to reproductive management. In this Review, we present prevalence rates, screening tools, and treatment recommendations for PCOS-related conditions, and we consider the diagnostic and clinical elements of optimal transition of care models that ensure continuity of comprehensive care for adolescents moving from the paediatric health-care system to the adult health-care system.

Integrative bioinformatics and experimental validation of hub genetic markers in acne vulgaris: Toward personalized diagnostic and therapeutic strategies

BACKGROUND

Acne vulgaris is a widespread chronic inflammatory dermatological condition. The precise molecular and genetic mechanisms of its pathogenesis remain incompletely understood. This research synthesizes existing databases, targeting a comprehensive exploration of core genetic markers.

METHODS

Gene expression datasets (GSE6475, GSE108110, and GSE53795) were retrieved from the GEO. Differentially expressed genes (DEGs) were identified using the limma package. Enrichment analyses were conducted using GSVA for pathway assessment and clusterProfiler for GO and KEGG analyses. PPI networks and immune cell infiltration were analyzed using the STRING database and ssGSEA, respectively. We investigated the correlation between hub gene biomarkers and immune cell infiltration using Spearman's rank analysis. ROC curve analysis validated the hub genes' diagnostic accuracy. miRNet, TarBase v8.0, and ChEA3 identified miRNA/transcription factor-gene interactions, while DrugBank delineated drug-gene interactions. Experiments utilized HaCaT cells stimulated with Propionibacterium acnes, treated with retinoic acid and methotrexate, and evaluated using RT-qPCR, ELISA, western blot, lentiviral transduction, CCK-8, wound-healing, and transwell assays.

RESULTS

There were 104 genes with consistent differences across the three datasets of paired acne and normal skin. Functional analyses emphasized the significant enrichment of these DEGs in immune-related pathways. PPI network analysis pinpointed hub genes PTPRC, CXCL8, ITGB2, and MMP9 as central players in acne pathogenesis. Elevated levels of specific immune cell infiltration in acne lesions corroborated the inflammatory nature of the disease. ROC curve analysis identified the acne diagnostic potential of four hub genes. Key miRNAs, particularly hsa-mir-124-3p, and central transcription factors like TFEC were noted as significant regulators. In vitro validation using HaCaT cells confirmed the upregulation of hub genes following Propionibacterium acnes exposure, while CXCL8 knockdown reduced pro-inflammatory cytokines, cell proliferation, and migration. DrugBank insights led to the exploration of retinoic acid and methotrexate, both of which mitigated gene expression upsurge and inflammatory mediator secretion.

CONCLUSION

This comprehensive study elucidated pivotal genes associated with acne pathogenesis, notably PTPRC, CXCL8, ITGB2, and MMP9. The findings underscore potential biomarkers, therapeutic targets, and the therapeutic potential of agents like retinoic acid and methotrexate. The congruence between bioinformatics and experimental validations suggests promising avenues for personalized acne treatments.

Efficacy of Topical Treatments in the Management of Mild-to-Moderate Acne Vulgaris: A Systematic Review

Acne vulgaris, commonly called acne, is a skin condition affecting many individuals globally. It is a chronic condition characterized by developing pimples, blackheads (open comedones), whiteheads (closed comedones), and other skin lesions. Acne usually appears on the face, neck, chest, and back. It is commonly associated with puberty and adolescence but can also affect adults of all ages. Acne can be very frustrating and embarrassing, leading to low self-esteem and social isolation. The condition arises from various factors, including clogged pores, excessive sebum production, bacteria, and inflammation. This systematic review assesses the effectiveness of topical antibiotics, retinoids, niacinamide, azelaic acid, and clascoterone in treating mild-to-moderate acne vulgaris. A comprehensive search across PubMed, PubMed Central, and Google Scholar yielded 10 articles focused on topical antibiotics, with findings from 198 subjects indicating the efficacy of doxycycline against inflammatory lesions. Retinoids, such as tretinoin and adapalene, significantly improved both lesion types (open and closed comedones). Niacinamide, examined in a randomized controlled trial involving 41 participants, reduced sebum production. Another study with 60 patients revealed that azelaic acid effectively reduced both inflammatory and non-inflammatory lesions. Clascoterone emerged as a promising antiandrogenic treatment, supported by a randomized controlled trial involving 4,440 patients. It is essential that individualized therapy, incorporating patient preferences and considering adverse effects, is emphasized for optimizing acne management.

The Promising Role of Polyphenols in Skin Disorders

The biochemical characteristics of polyphenols contribute to their numerous advantageous impacts on human health. The existing research suggests that plant phenolics, whether consumed orally or applied directly to the skin, can be beneficial in alleviating symptoms and avoiding the development of many skin disorders. Phenolic compounds, which are both harmless and naturally present, exhibit significant potential in terms of counteracting the effects of skin damage, aging, diseases, wounds, and burns. Moreover, polyphenols play a preventive role and possess the ability to delay the progression of several skin disorders, ranging from small and discomforting to severe and potentially life-threatening ones. This article provides a concise overview of recent research on the potential therapeutic application of polyphenols for skin conditions. It specifically highlights studies that have investigated clinical trials and the use of polyphenol-based nanoformulations for the treatment of different skin ailments.

The Role of the Gut Microbiome and Microbial Dysbiosis in Common Skin Diseases

Dermatoses are an increasingly common problem, particularly in developed countries. The causes of this phenomenon include genetic factors and environmental elements. More and more scientific reports suggest that the gut microbiome, more specifically its dysbiosis, also plays an important role in the induction and progression of diseases, including dermatological diseases. The gut microbiome is recognised as the largest endocrine organ, and has a key function in maintaining human homeostasis. In this review, the authors will take a close look at the link between the gut-skin axis and the pathogenesis of dermatoses such as atopic dermatitis, psoriasis, alopecia areata, and acne. The authors will also focus on the role of probiotics in remodelling the microbiome and the alleviation of dermatoses.

Resolving acne with optimized adapalene microspongeal gel, in vivo and clinical evaluations

In our pursuit of enhancing acne treatment while minimizing side effects, we developed tailored Adapalene microsponges (MS) optimized using a Box-Behnken design 33. The independent variables, Eudragit RS100 percentage in the polymer mixture, organic phase volume, and drug to polymer percentage, were explored. The optimized formulation exhibited remarkable characteristics, with a 98.3% ± 1.6 production yield, 97.3% ± 1.64 entrapment efficiency, and a particle size of 31.8 ± 1.1 µm. Notably, it achieved a 24 h cumulative drug release of 75.1% ± 1.4. To delve deeper into its efficacy, we evaluated the optimized microspongeal-gel in vitro, in vivo, and clinically. It demonstrated impressive retention in the pilosebaceous unit, a target for acne treatment. Comparative studies between our optimized Adapalene microspongeal gel and marketed Adapalene revealed superior performance. In vivo studies on Propionibacterium acnes-infected mice ears showed a remarkable 97% reduction in ear thickness, accompanied by a significant decrease in inflammatory signs and NF-κB levels, as confirmed by histopathological and histochemical examination. Moreover, in preliminary clinical evaluation, it demonstrated outstanding effectiveness in reducing comedonal lesions while causing fewer irritations. This not only indicates its potential for clinical application but also underscores its ability to enhance patient satisfaction, paving the way for future commercialization.

The Impact of Consuming Probiotics and Following a Vegetarian Diet on the Outcomes of Acne

Acne vulgaris is a common skin condition that affects millions of people worldwide. While the exact cause of acne is not fully understood, it is believed to be influenced by various factors such as the skin microbiome, host immunity, hormones, genetics, and possibly diet. There are several treatment options for acne, including antibiotics and vitamin A derivatives (retinoids). However, these treatments can have side effects, such as dryness, redness, and peeling of the skin. The relationship between diet and acne remains somewhat controversial. Studies have found that Western societies have a higher incidence of acne than non-Western societies, which is believed to be due to dietary differences. Several experiments were conducted to target the skin microbiome and treat acne with the hope of using probiotics orally or topically to regulate the immune response and reduce inflammation in acne. In addition, studies have shown that a plant-based diet can benefit individuals with acne. Avoiding dairy consumption is one of the most effective dietary changes for reducing acne. As part of our investigation, we conducted a review to determine the effect of probiotics and vegetarian diets on acne.

Scientometric analysis of trends in global research on acne treatment

Acne or acne vulgaris is the most common chronic inflammatory disease of the sebaceous follicles.

Objectives

The present study aims to identify the main lines of research in the field of acne treatment using reproducible scientometric methods. In this article, we reviewed the following research trends: facial acne, different antibiotics, retinoids, anti-inflammatory drugs, epidermal growth factor receptor inhibitors therapy, and associated diseases.

Methods

The analysis of publications from the PubMed collection was carried out from 1871 to 2022. All data were analyzed using Microsoft Excel. The evolution of the terminological portrait of the disease is shown.

Results

Trends in the use of various groups of antibiotics, retinoids, anti-inflammatory drugs, and photodynamic therapy for acne treatment have been found. There is a growing interest in clindamycin and doxycycline (polynomial and exponential growth, respectively). The effects of isotretinoin are also being studied more frequently (active linear growth). The publication of studies on spironolactone is increasing (linear growth). There is also a steady interest in the use of epidermal growth factor receptor inhibitors in the recent years. There is active research on acne and polycystic ovary syndrome (exponential growth).

Limitations

Only articles in English were selected. The most frequent terms were considered.

Conclusions

The dynamics of publication activity in the field of acne was considered. The aim of the current scientometric study was to analyze the global trends in acne treatments. The trend analysis made it possible to identify the most explored areas of research, as well as indicate those areas in dermatology in which interest is declining.

Acne accounts for an almost 2.5-fold higher proportion of dermatology visits among adult females compared to adult males in the United States: A study of the national ambulatory medical care survey from 2002-2016

BACKGROUND

Acne vulgaris affects a significant number of females into adulthood. Juvenile acne and adult acne have different presentations and potentially distinctive pathogeneses. However, patterns in treatments specifically related to the adult female population have previously not been studied.

METHODS

Retrospective database analysis of healthcare utilization and medications prescribed for acne using the National Ambulatory Medical Care Survey (NAMCS) data from 2002-2016 was performed.

RESULTS

After age 20, acne accounted for an almost 2.5-fold higher proportion of dermatology visits among females compared to males (10.1% vs. 4.1%, P < 0.001). Tetracycline-class antibiotics were the most prescribed therapy within all age groups of females between 2002-2016. However, there was also a substantial rise in prescriptions of spironolactone beginning in 2012.

CONCLUSION

A significantly greater proportion of dermatology visits by adult females are for acne in comparison to adult males. Tetracycline-class antibiotics remain the most prescribed therapy in adult age groups despite a potentially different pathogenesis of adult acne. Therefore, there is a need for further studies comparing the effectiveness of therapies specifically for adult female acne.

Nanotechnology and narasin: a powerful combination against acne

Acne vulgaris is widely regarded as the most prevalent skin disorder characterized by painful, inflammatory skin lesions that are primarily attributed to the pathogenic actions of Cutibacterium acnes (C. acnes). To improve the clinical management of this disease, there is a pressing clinical demand to develop innovative antibacterial therapies that utilize novel mechanisms. The current research aimed to discover the antibacterial efficacy of narasin (NAR), a polyether ionophore, against drug-resistant acne bacteria. In addition, the study aimed to formulate self-nanomicellizing solid dispersions (SNMSD), utilizing Soluplus® (SOL), as a drug delivery system to incorporate NAR and selectively target the lipophilic C. acnes abundant environments within the skin. Furthermore, the study aimed to investigate the ex vivo deposition and permeation of NAR into the various layers of the skin using full-thickness porcine ear skin as a model skin. By encapsulating NAR within spherical polymeric micelles (dn < 80 nm) aqueous solubility was significantly increased by approximately 100-fold (from <40 μg mL-1 to 4600 μg mL-1). Following optimization, the micelle solution was integrated into a gel formulation (containing 0.2% w/v NAR) and evaluated for stability over 4 weeks at room temperature (drug content >98%). Results from drug deposition and permeation experiments demonstrated that the deposition of NAR from the NAR-micelle solution and its gel formulation into the lipophilic stratum corneum (19 835.60 ± 6237.89 ng cm-2 and 40 601.14 ± 3736.09 ng cm-2) and epidermis (19 347 ± 1912.98 ng cm-2 and 18 763.54 ± 580.77 ng cm-2) was superior to that of NAR in solution, which failed to penetrate any skin layers. In conclusion, the outcomes of this study provide evidence that NAR exhibits promising activity against antimicrobial resistant strains of C. acnes (MIC range ≤0.008-0.062) and that micelle nanocarriers can improve the aqueous solubility of poorly water-soluble drugs. Furthermore, our results highlight the ability of nanomicelles to enable selective and targeted drug delivery to the lipophilic skin layers.

Correlating the Gut Microbiota and Circulating Hormones with Acne Lesion Counts and Skin Biophysical Features

Acne vulgaris is a common inflammatory condition that is multi-factorial and impacted by both intrinsic and extrinsic features. Several previous studies have assessed for correlations between factors such as circulating hormones, stress, or the microbiome. However, there have not been any correlations specifically against lesion counts or differentiating correlations between inflammatory and non-inflammatory lesion counts. Here, we correlate several factors against acne lesions. Twenty men and women with mild to moderate acne were recruited, and their hormonal levels and their gut microbiome were collected and correlated against their inflammatory and non-inflammatory lesions of acne. Facial non-inflammatory lesions were weakly correlated to sebum excretion rate and weakly inversely correlated to forehead and cheek hydration. We examined stress through the use of a normalized peak-to-trough ratio (higher numbers indicated less stress), which correlated with skin hydration and inversely correlated with sebum excretion rate. Sebum excretion rate was weakly correlated to testosterone levels, and facial hydration correlated with estradiol levels. Correlations with the gut microbiome showed differential correlations with inflammatory and non-inflammatory lesions, with Clostridium sp AF 23-8 correlating to inflammatory lesion counts, while Actinomyces naeslundii str Howell 279 correlated to non-inflammatory lesions. Overall, measures of stress and circulating hormones correlate to skin biophysical properties and acne lesion counts. Also, different gut bacteria correlate with either inflammatory or non-inflammatory lesion counts. We hope that our findings stimulate further work on the gut-mind-stress-skin axis within acne.

Efficacy and Safety of Detachable Microneedle Patch Containing Triamcinolone Acetonide in the Treatment of Inflammatory Acne

Background

Detachable microneedles (DMNs) are dissolvable microneedles that detach from the base during administration. The use of DMNs-containing steroids for acne has never been investigated.

Methods

Thirty-five patients with facial inflammatory acne were evaluated for acne treatment efficacy and safety of DMNs and DMNs containing triamcinolone acetonide (TA) via a 28-day randomized, double-blind, controlled trial. Four inflammatory acne lesions were selected from each participant and randomly treated with a single application of 700 µm DMNs containing 262.02 ± 15.62 µg TA (700DMNTA), 1000 µm DMNs containing 160.00 ± 34.92 µg TA (1000DMNTA), 700 µm DMN without TA (700DMN), and a control. Efficacy was measured by assessing physical grading, diameter, volume, erythema index, and melanin index. Safety was evaluated by assessing reports of adverse effects from patients and physicians.

Results

All three treatment groups achieved resolution of inflammatory acne significantly faster than the control group, with median times for resolution of 4.6, 5.25, 6.7, and 8.1 days in the 1000DMNTA, 700DMNTA, 700DMN, and control, respectively. When compared to the control group, the diameters and post-acne erythema of inflammatory acne were significantly reduced in the treatment groups. The 1000DMNTA decreased acne size and erythema more than other treatments. DMNTA also tended to decrease acne size and erythema more than DMN with no TA, but there was no statistically significant difference. All participants preferred DMN over conventional intralesional steroid injection due to less pain and self-application. No adverse effect was observed.

Conclusion

DMNTA is a safe, effective alternative treatment for inflammatory acne and significantly reduces post-acne erythema.

Maternal androgen excess increases the risk of pre-diabetes mellitus in male offspring in later life: a long-term population-based follow-up study

PURPOSE

Prenatal androgen exposure could be a source of early programming, leading to the development of cardiometabolic diseases in later life. In this study, we aimed to examine cardiometabolic disturbances in males exposed to maternal androgen excess during their prenatal life.

METHODS

In this prospective population-based study, 409 male offspring with maternal hyperandrogenism (MHA), and 954 male offspring without MHA, as controls, were included. Both groups of male offspring were followed from the baseline to the date of the incidence of events, censoring, or end of the study period, whichever came first. Age-scaled unadjusted and adjusted Cox regression models were applied to assess the hazard ratios (HR) and 95% confidence intervals (CIs) for the association between MHA with pre-diabetes mellitus (Pre-DM), type 2 diabetes mellitus (T2DM), pre-hypertension (Pre-HTN), hypertension (HTN), dyslipidemia, overweight, and obesity in the offspring of both groups. Statistical analysis was performed using the STATA software package; the significance level was set at P < 0.05.

RESULTS

A higher risk of Pre-DM (adjusted HR: 1.46 (1.20, 1.78)) was observed in male offspring with MHA after adjustment for potential confounders, including body mass index, education, and physical activity. However, no significant differences were observed in the risk of T2DM, Pre-HTN, HTN, dyslipidemia, overweight, and obesity in males with MHA compared to controls in both the unadjusted and adjusted models.

CONCLUSION

Maternal androgen excess increases the risk of Pre-DM in male offspring in later life. More longitudinal studies with long enough follow-up are needed to clarify the effects of MHA on the cardiometabolic risk factors of male offspring in later life.

Flavonoids as Promising Natural Compounds in the Prevention and Treatment of Selected Skin Diseases

Phytochemicals represent a large and diverse group of naturally occurring compounds, bioactive nutrients, or phytonutrients produced by plants, widely found in fruits, vegetables, whole grains products, legumes, beans, herbs, seeds, nuts, tea, and dark chocolate. They are classified according to their chemical structures and functional properties. Flavonoids belong to the phenolic class of phytochemicals with potential solid pharmacological effects as modulators of multiple signal transduction pathways. Their beneficial effect on the human body is associated with their antioxidant, anti-inflammatory, antimutagenic, and anticarcinogenic properties. Flavonoids are also widely used in various nutritional, pharmaceutical, medical, and cosmetic applications. In our review, we discuss the positive effect of flavonoids on chronic skin diseases such as vitiligo, psoriasis, acne, and atopic dermatitis.

Acne Vulgaris Relapse in Sudanese Patients Treated with Oral Isotretinoin: Rate and Predictive Factors

Purpose

Acne vulgaris is a skin disorder primarily affecting teenagers and young adults. Acne relapse is the main drawback of oral isotretinoin (OI), which is the golden therapy for severe acne. This study aimed to assess the rate and predictive factors of acne relapse among Sudanese patients using OI.

Patients and Methods

A cross-sectional study was conducted in a dermatology and venereology clinic-Sudan, using a self-administered questionnaire and data collection sheet. Patients using OI for acne treatment were enrolled in the study. Chi-square test and logistic regression analysis were used to evaluate the association between variables. P-value <0.05 was considered statistically significant.

Results

225 acne patients (mean age: 26.0±4.2 years, females: 88.9%) were included in this study. OI daily dose ranged from 0.25 to 1 mg/kg/day, with frequent daily doses of 40-49 mg (57.3%) over 3-6 months (81.8%). Around one-third of patients (36%) received maintenance therapy after completion of OI course. At a 2-year follow-up, approximately 36% of patients experienced acne relapse that commonly occurred within 6-18 months after the last OI therapy. Early discontinuation of OI was a positive predictor of acne relapse which was 3.99 times greater in patients who had early discontinued OI than those completing the planned OI course (OR=3.99; p=0.002). OI cumulative doses of 120-139 mg/kg and 140-159 mg/kg were negative predictors of acne relapse (OR=0.23; p=0.001 and OR=0.15; p=0.02, respectively). Most patients (94.2%) received prescription OI, and 76.4% of women were advised to use contraceptives. About 69% of patients practiced skin care.

Conclusion

About one-third of patients experienced acne relapse. Early discontinuation and low cumulative doses of OI are the main risk factors for acne relapse. Long-term therapy of OI, with cumulative doses of 120-159 mg/kg, would be beneficial to reduce acne relapse.

Prospective Evaluation of a Topical Botanical Skin Care Regimen on Mild to Moderate Facial and Truncal Acne and Mood

Acne vulgaris is a common inflammatory condition that can be associated with profound psychosocial impacts. Conventional treatment includes topical retinoids, benzoyl peroxide, and antimicrobials, and some may cause irritation and skin dryness. In this 8-week open-label study, we examined the effects of a botanical skin care regimen (Codex Labs Shaant Balancing regimen) on mild to moderate facial and truncal acne. Twenty-four male and female subjects between the ages of 12 and 45 years were assessed for eligibility, 20 were enrolled, and 15 completed all study visits. Facial and truncal acne lesion counts, skin hydration, sebum excretion rate, and mood were assessed at baseline, week 4, and week 8. Total facial lesion counts (inflammatory and non-inflammatory lesions) decreased by 20.5% at week 4 (p = 0.06) and by 25.2% at week 8 (p < 0.05). Inflammatory lesion counts on the trunk were found to decrease at week 8 relative to baseline by 48% (p < 0.05). Forehead sebum excretion rate decreased by 40% at week 4 (p = 0.07) and 22% at week 8 (p = 0.08), and cheek skin hydration increased by 27.6% at week 4 (p = 0.14) and 65% at week 8 (p = 0.10). Participants also experienced significant improvement in components of a positive effect, such as feeling "strong" and "inspired", and a decrease in negative effects, such as feeling "irritable." Overall, the botanical skin care regimen was found to be well-tolerated. Our study suggests that a botanical skin care regimen may reduce facial and truncal acne lesion counts, increase skin hydration, reduce sebum production, and augment positive effects and moods in those with mild to moderate facial and truncal acne.

Stabilization of Acne Vulgaris-Associated Microbial Dysbiosis with 2% Supramolecular Salicylic Acid

Facial microbiota dysbiosis is an important factor in causing acne vulgaris. The present study aimed to analyze the effect of 2% Supramolecular Salicylic Acid (SSA) on acne-associated facial bacteria. In the current study, 30 acne vulgaris patients (treated with 2% SSA for eight weeks) and ten volunteers with no facial acne were selected. Samples from acne patients (before and after treatment) and volunteers (not treated) were analyzed via high throughput sequencing, Deblur algorithm, and R microbiome package. After treatment with 2% SSA, the total lesion count and global acne grading system (GAGS) score reduced significantly (p < 0.001). Metagenomic sequencing analysis revealed that the pre-treated acne group had low α and deviated β diversity compared to the control and post-treated acne groups. Due to the treatment with 2% SSA, α diversity index was increased and β diversity was stabilized significantly (p < 0.001). The relative abundance of bacterial genera in the pre-treated acne group was uneven and had a high proportion of Staphylococcus, Ralstonia, and Streptococcus. The proportion of these three genera was significantly decreased in the post-treated group, and overall bacteria genera distribution tends toward the healthy individual. It is concluded that 2% SSA normalizes the microbial communities associated with the skin.

Evaluation of Psychiatric Comorbidities and Quality of Life As Well As Brain-Derived Neurotrophic Factor (BDNF) Concentrations Among Patients Suffering From Acne Vulgaris: A Systematic Review and Meta-Analysis

Acne vulgaris usually affects the dermal layer of the skin and is revealed frequently in young adulthood and adolescence. It has serious psychosocial comorbidities. We conducted the present systematic review and meta-analysis to elucidate the association of acne vulgaris with psychiatric comorbidities and quality of life as well as the brain-derived neurotrophic factor (BDNF) level. A systematic review and meta-analysis of the published articles were carried out following the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. We investigated diverse databases: Web of Science, PubMed, the Cochrane Library, Embase, PsycINFO, and CINAHL to search for articles reporting the prevalence of psychosocial comorbidities among patients with acne vulgaris from database inception through June 2022. The outcomes were depression, anxiety, symptom checklist-90-R (SCL-90-R), quality of life, self-esteem, stress, loneliness, and BDNF concentrations. Of 3647 articles identified, 23 met the inclusion criteria. Patients with acne vulgaris have a significantly higher level of anxiety, depression, and stress (P<0.05). Yet, the reported findings of the SCL-90-R, self-esteem, loneliness, and BDNF scores among patients suffering from acne vulgaris were variable and did not differ significantly compared to healthy participants (P>0.05), hampering any conclusive findings on absolute prevalence. Subgroup analysis and comparison showed that heterogeneity between studies was likely due to factors, including country, study design, and assessment tools. This comprehensive review and meta-analysis revealed that anxiety, depression, and stress are significantly more frequent among patients suffering from acne vulgaris. These findings confirm that acne vulgaris has both psychiatric and medical characteristics and requires a multidisciplinary approach.

Evaluation of the safety and efficacy of a fractional picosecond 1064 nm laser for post-acne erythema in adult Chinese patients

OBJECTIVE

To evaluate the efficacy and safety of fractional 1064 nm picosecond Nd:YAG laser (FPNYL) in the treatment of post-acne erythema (PAE) of adult Chinese.

MATERIALS AND METHODS

A total of 22 patients received 1 session of treatment and were followed up at the eighth week. Primary outcomes were measured by the Clinician erythema assessment scale (CEAS). Secondary outcomes included a global aesthetic improvement scale (GAIS) and patients' assessment of satisfaction on a five-point scale. Pain scores and adverse effects were also evaluated.

RESULTS

Twenty-two patients with Fitzpatrick skin types III and IV were enrolled in the study and completed all treatments and follow-up visits. The mean CEAS scores fell from 2.74 ± 0.80 to 1.95 ± 0.75 (p < 0.05). The mean GAIS of PAE improvement was 2.46 ± 0.68. Erythema percentile scores by VISIA increased from 32.63 ± 7.0 to 45.75 ± 11.45 (t = 5.442, p = 0). The patient satisfaction score was 1.86 ± 1.17. The pain scores were 3.27 ± 1.17 for the FPNYL treatment (varied from 2 to 6). There were moderate erythema and oedema, which last for 3.84 ± 0.78 days. There were overall 68.18% (15/22) patients who felt pruritus in different degrees and 27.27% patients who encountered acne eruptions (white head type). No scar, hyperpigmentation or hypopigmentation was found.

CONCLUSION

Treatment with fractional 1064 nm picosecond Nd:YAG laser is effective and safe for PAE of Chinese patients.

Long‐pulsed Nd: YAG laser (1064 nm) versus intralesional botulinum toxin type (A) in acne vulgaris therapy: a split face study

BACKGROUND

Acne can be considered more than a cosmetic concern due to its large impact on patients' quality of life. There are various therapeutic options for inflammatory acne, but inconvenience and undesirable side effects prompted a search for more acceptable treatments. This study aimed to compare the clinical efficacy and safety of long-pulsed Nd: YAG laser 1064 nm versus intralesional botulinum toxin type-A (BTX-A) in inflammatory acne therapy.

METHODS

A prospective randomized split-face comparative study involved 30 patients with inflammatory acne. Each patient received long-pulsed Nd: YAG 1064 nm laser on one side, and intralesional BTX-A on the other side, monthly until improvement or maximum three sessions. Cases were assessed by acne lesions counting and grading of severity by Investigator's Global Assessment of acne (IGAs) at baseline, each session, and after 3 months follow-up.

RESULTS

A highly statistically significant improvement in lesions count and IGAs for both sides was observed, with statistically non-significant difference between both sides at end of treatment sessions. While, after 3 months follow-up, there was a more significant improvement at laser side.

CONCLUSION

Both long-pulsed Nd: YAG laser 1064 nm and intralesional BTX-A are safe and effective for acne therapy. Nd-YAG laser has a more prolonged efficacy and lower recurrence rate than intralesional BTX-A.

Efficacy and Tolerability of HydraFacial Clarifying Treatment Series in the Treatment of Active Acne Vulgaris

OBJECTIVE

This 12-week, multicenter, open-label study investigated the efficacy and tolerability of the HydraFacial Clarifying Treatment for improving skin appearance in patients who present with acne vulgaris.

METHODS

Twenty eligible adult patients with mild-to-moderate acne were enrolled at one of two treatment sites in the United States and were to undergo six HydraFacial Clarifying Treatments, one every two weeks for 12 weeks. Treatment occurs in three steps: cleansing and peeling; suction to extract dead skin cells, sebum, and debris; and application of blue LED light. Acne severity was graded by investigators and by patients using the Global Acne Severity Score (GASS).

RESULTS

The proportion of patients with no acne or almost clear skin (GASS ≤1) at baseline versus final treatment increased from 20 to 65 percent per investigator assessment (p=0.0027), and from 5 to 55 percent per patient self-report (p=0.0016). At final treatment, more than 80 to 100 percent of both investigators and patients agreed or strongly agreed there was an improvement in skin appearance across multiple assessment parameters. Treatments were generally well tolerated.

LIMITATIONS

Due to the nature of the treatment, blinding of neither investigators nor patients was feasible.

CONCLUSION

The results presented here suggest that a series of six HydraFacial Clarifying Treatments improves overall skin appearance in patients with active acne.

Clinical evaluation of anti-aging effects of combined therapy-Azelaic acid, phytic acid, and vitamin C applied layer by layer in females with Fitzpatrick skin types II and III

INTRODUCTION

Vitamins C, E, and A and substances of plant origin, including azelaic acid and phytic acid are frequently used in cosmetic preparations to counteract oxidative stress and negative effects of free radicals. The aim of the study was to evaluate a novel combined therapy consisting of azelaic acid, ascorbic acid, and phytic acid applied layer on layer.

METHODS

Twenty study participants received a series of eight treatments performed every 7 days. Twenty percent azelaic acid and then 30% phytic acid were applied to the entire face, while 40% l-ascorbic acid only on the left side. The preparations were applied layer by layer. Skin parameters were measured before the series of treatments (T0), after the series of eight treatments (T1-8 weeks), and 1 month after the end of the treatment (T2-12 weeks).

RESULTS

The application of two and three active compounds resulted in a significant improvement in erythema and hyperpigmentation both on the forehead and the cheeks, however, more pronounced effects were observed when all the three active compounds were used. Both applied types of treatment considerably increased skin moisture. All the participants (100%) were satisfied with the effects of the treatment. A majority of them reported an improvement in skin hydration, firmness, and elasticity, more uniform skin tone and a reduction of skin redness and wrinkles.

CONCLUSIONS

Topical application of these active compounds resulted in improvement of skin elasticity and flexibility, reduction of wrinkles, hyperpigmentation, erythema, and telangiectasia as well as amelioration of skin tone.

Relation Between Non-Alcoholic Fatty Pancreas and Clinical and Biochemical Parameters in Women with Polycystic Ovary Syndrome: A Multi-Centric Study

BACKGROUND

Polycystic ovary syndrome (PCOS) is the most common endocrinological disease affecting women in the reproductive age. Non-alcoholic fatty pancreas disease (NAFPD) can promote many aspects of pancreatic dysfunction. The present study aimed to determine the prevalence of NAFPD and to identify its association with clinical and biochemical parameters in PCOS patients.

METHODS

The present study included 150 patients with PCOS and 150 age-matched healthy controls. All patients were submitted to careful history taking and thorough clinical examination. Performed laboratory investigations included fasting and postprandial blood glucose, lipid profile, liver function tests, serum prolactin and total testosterone. Fatty pancreas was diagnosed using abdominal ultrasound.

RESULTS

Among PCOS women, NAFPD was diagnosed in 57 women (38.0%) in contrast to 18 women (12.0%) in the control group (p < 0.001). Patients with NAFPD were significantly older [median (IQR): 38.0 (35.0-43.0) versus 29.0 (25.5-33.0) years, p = 0.001] with higher BMI [median (IQR): 31.5 (29.1-34.7) versus 30.4 (28.6-32.4) kg/m2, 0.042]. Moreover, they had significantly higher frequency of metabolic syndrome (84.2% versus 54.8%, p = 0.001), insulin resistance (68.4% versus 26.9%, p < 0.001) and severe NAFLD (22.8% versus 2.2%, p < 0.001). NAFPD patients had significantly lower sex hormone binding globulin (SHBG) [median (IQR): 36.0 (30.8-40.7) versus 38.1 (35.15-42.7), p = 0.002] and significantly higher free androgen index (FAI) [median (IQR): 4.08 (3.3-4.92) versus 3.47 (3.12-4.05), p < 0.001].

CONCLUSION

NAFPD is prevalent PCOS. It is related to metabolic syndrome, insulin resistance, dyslipidemia and hyperandrogenism.

Efficacy of a retinoid complex plus anti-inflammatory component cream alone or in combination with prebiotic food supplement in adult acne: A randomized, assessor-blinded, parallel-group, multicenter trial on 184 women

BACKGROUND

Adult female acne (AFA) nowadays is a very common skin condition affecting mainly women aged between 25 and 40. The treatment of AFA could be challenging.

STUDY AIM

We evaluate and compare the efficacy and tolerability of a cream formulation containing two retinoid molecules (hydroxypinacolone/retinyl palmitate) combined with Iris Florentina root extract and a complex of three oligopeptides (C) applied twice a day (morning and evening) alone or in combination (C + O) with a food supplement containing a mixture of prebiotic molecules (FOS&GOS) zinc, lactoferrin, and niacinamide.

SUBJECTS AND METHODS

In a multicenter, randomized, assessor-blinded, 12-week trial, we assessed the efficacy of these two regimens in the evolution of AFA lesions (non-inflammatory: NI-L; inflammatory: IL; and total number of lesions: TL). Additional efficacy endpoints were the evolution of the 6-point (from 0 to 5) GEA and Adult Female Acne Scoring Tool (AFAST) scores.

RESULTS

One hundred and eighty-four women (mean age 32 ± 6 years) with AFA agreed to participate after obtaining informed consent. They were randomized (2:1) to the topical product (n = 123) (Group C) or to the combination (n = 61) (Group C + O) treatment. All enrolled patients concluded the trial with no drop-out. At baseline, NI-L, IL, and TL acne lesion count were 15 ± 9, 9 ± 5, and 24 ± 14 in the Group C and 19 ± 8, 9 ± 4, and 29 ± 10 in Group C + O. In comparison with the number of the acne lesions at the baseline, both treatment regimens induced a significant reduction (p = 0.0001, ANOVA test) at Week 12 in NI-L, IL, and TL by -54%, -63%, and - 59% in Group C and by -55%, -73%, and - 61% in the Group C + O, respectively. At Week 12, the absolute IL count reduction vs. baseline was significantly (p = 0.0158) greater in Group C + O (-7.0) in comparison with Group C (-5.5). The GEA absolute score reduction in Group C + O group was significantly greater in comparison with Group C (-1.5 vs. -1.1; p = 0.0097). In the Group C + O, a greater percentage of success treatment (defined as a GEA score of 0/1 at Week 12) was observed in comparison with Group C (39% vs. 27%; p = 0.06). AFAST score at baseline was 2.4 ± 0.5 in group C and 2.8 ± 0.6 in group C + O. AFAST score was reduced by 21% and by 51% after 6 and 12 weeks of treatment in group C and by 22% and 55% in group C + O, respectively. Both treatment regimens were well tolerated. Not relevant adverse events were recorded.

CONCLUSION

A cream containing retinoid molecules and Iris Florentina root extract is effective and well tolerated in the management of AFA. The treatment combination with a prebiotic and anti-inflammatory food supplement offers an additional clinical benefit mainly in reducing inflammatory lesions and improving the severity acne score.

Influence of Selected Food Product Groups Consumption Frequency on Acne-Related Quality of Life in a National Sample of Polish Female Adolescents

Acne vulgaris affects over 80% of adolescents, mainly female ones, and may reduce their general quality of life, so its prevention and treatment are becoming necessary, while among the options for acne management, the potential influence of diet is indicated. The aim of the study was to assess the influence of selected food product groups consumption frequency on acne-related quality of life in a national sample of Polish female adolescents. The studied population of 1370 Polish female adolescents was gathered using random quota sampling of secondary schools representative of the whole country. The acne-related quality of life was assessed using the Acne Quality of Life (AQoL) Scale with the calculated Social Quality of Life (SOCQOL) Score, as well as the Acne Disability Questionnaire (ADQ) with the calculated Cardiff Acne Disability Index (CADI). The acne-related food product groups' consumption frequency was assessed using the Acne-specific Food Frequency Questionnaire (Acne-FFQ). There were no differences in food product consumption between subgroups stratified by the acne-related quality of life (p > 0.05), and there was no correlation between food product consumption and the results of the SOCQOL Score (p > 0.05). For the CADI, positive correlations were indicated for fast foods (p = 0.0450; R = 0.0688), salty snacks (p = 0.0342; R = 0.0727), and chocolate confectionary (p = 0.0147; R = 0.0837), while a negative correlation was indicated for dairy beverages other than milk (p = 0.0414; R = -0.0701). In the studied group of Polish female adolescents, fast foods, salty snacks, and chocolate confectionary were indicated as potential acne-promoting factors, while dairy beverages other than milk were indicated as a potential acne-protective factor.

In Vitro Antibacterial and Anti-Inflammatory Activity of Arctostaphylos uva-ursi Leaf Extract against Cutibacterium acnes

Cutibacterium acnes (C. acnes) is the main causative agent of acne vulgaris. The study aims to evaluate the antimicrobial activity of a natural product, Arctostaphylos uva-ursi leaf extract, against C. acnes. Preliminary chemical–physical characterization of the extract was carried out by means of FT-IR, TGA and XPS analyses. Skin permeation kinetics of the extract conveyed by a toning lotion was studied in vitro by Franz diffusion cell, monitoring the permeated arbutin (as the target component of the extract) and the total phenols by HPLC and UV-visible spectrophotometry, respectively. Antimicrobial activity and time-killing assays were performed to evaluate the effects of Arctostaphylos uva-ursi leaf extract against planktonic C. acnes. The influence of different Arctostaphylos uva-ursi leaf extract concentrations on the biofilm biomass inhibition and degradation was evaluated by the crystal violet (CV) method. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) test was used to determine the viability of immortalized human keratinocytes (HaCaT) after exposure to Arctostaphylos uva-ursi leaf extract for 24 and 48 h. Levels of interleukin (IL)-1β, IL-6, IL-8 and tumour necrosis factor (TNF)-α were quantified after HaCaT cells cotreatment with Arctostaphylos uva-ursi leaf extract and heat-killed C. acnes. The minimum inhibitory concentration (MIC) which exerted a bacteriostatic action on 90% of planktonic C. acnes (MIC₉₀) was 0.6 mg/mL. Furthermore, MIC and sub-MIC concentrations influenced the biofilm formation phases, recording a percentage of inhibition that exceeded 50 and 40% at 0.6 and 0.3 mg/mL. Arctostaphylos uva-ursi leaf extract disrupted biofilm biomass of 57 and 45% at the same concentrations mentioned above. Active Arctostaphylos uva-ursi leaf extract doses did not affect the viability of HaCaT cells. On the other hand, at 1.25 and 0.6 mg/mL, complete inhibition of the secretion of pro-inflammatory cytokines was recorded. Taken together, these results indicate that Arctostaphylos uva-ursi leaf extract could represent a natural product to counter the virulence of C. acnes, representing a new alternative therapeutic option for the treatment of acne vulgaris.

Compatibility of Personalized Formulations in Cleoderm™, A Skin Rebalancing Cream Base for Oily and Sensitive Skin

Inflammatory skin conditions are prevalent in the general population and are a source of much concern for those who suffer from them. Acne is an extremely common condition and can significantly impact the quality of life of affected patients. Rosacea is another common dermatological disorder that often affects the face and can present with flushing, irritated skin, and pimples. In addition to being key for acne and rosacea, inflammation can also play a role in prematurely aging skin and contributes to the formation of wrinkles. Given the prevalence and patient impact of dermatological conditions on the face, such as those previously described, there is a demand for personalized medicines to manage these conditions when commercially available options are unsuitable, unavailable, or insufficient to fully resolve the condition. When designing an appropriate personalized therapy for a patient, both the vehicle and the active pharmaceutical ingredient choices are key to the success of the treatment. Cleoderm™ is a topical cream designed for use as a vehicle for the preparation of dermatological treatments by compounding pharmacies. Its ingredient profile was specifically curated to be gentle on the skin, allowing its use as a vehicle for compounded preparations that may be applied to sensitive and affected skin. In this bracketed study, benzoyl peroxide, cyproterone acetate, estriol, metronidazole, niacinamide, progesterone, retinoic acid, spironolactone, and tranexamic acid were selected, due to their known applications for dermatological skin conditions. To evaluate the compatibility and stability of Cleoderm™ in these formulations, high-performance liquid chromatography, followed by antimicrobial effectiveness testing, were performed for 180 days. For most formulations, a beyond-use date of 180 days was observed when stored at room temperature, except for retinoic acid, which had a beyond-use date of 30 days. Through the outcomes of this study, we concluded that Cleoderm™ presents increased convenience for both the compounding pharmacist and the patient, suggesting that it is an adequate candidate vehicle for compounding different dermatological formulations with adequate stability, presenting itself as a good alternative to commercially available treatments that cannot be personalized.

The Social and Psychological Impact of Acne Treatment: A Cross-Sectional Study of Blood Donors

BACKGROUND

Acne in adolescence and adulthood is believed to have a long-term impact on socioeconomic status (SES) and health-related quality-of-life (HRQoL) in adults.

OBJECTIVE

To estimate the cross-sectional prevalence of medically treated (MedTreAc) and untreated acne (UnTreAc) and to characterize its long-term impact in adults.

METHODS

A nationwide cross-sectional study on 17 428 blood donors aged 18-35 was performed. Associations among acne and HRQoL, depressive symptoms, total income, and SES were investigated via linear/logistic/multinomial logistic regression analyses adjusted for relevant covariables. HRQoL was measured by the Short Form-12, and depressive symptoms by the Major Depression Inventory. The data were self-reported.

RESULTS

Of the participants, 3591 (20.6%) and 1354 (7.8%) identified as the MedTreAc and UnTreAc phenotype, respectively. Neither phenotype was associated with a long-term impact on total income, but the MedTreAc group was associated with being an apprentice/student (OR = 1.26; 95% CI: 1.12, 1.42; P = 1.3×10^-4) or high skill-level employee (OR = 1.22, 95% CI: 1.07; 1.39, P = .0023), while self-employment was more common for those with UnTreAc (OR = 1.53; 95% CI: 1.12, 2.06, P = .0061). Additionally, the UnTreAc group was associated with a lower mental HRQoL (SF-12 mental component summary score -1.05, 95% CI: -1.56, -0.54; P = 1.4×10^-9) and increased odds ratio of depressive symptoms (OR = 1.44; 95% CI: 1.00, 2.02, P = .046).

CONCLUSION

In this population of blood donors, the cumulative prevalence of MedTreAc and UnTreAc were 20.6% and 7.8%, respectively. Untreated acne had a long-term impact on psychosocial well-being in adulthood. It was associated with lower mental HRQoL and higher occurrence of depressive symptoms. Acne was not associated with a lower salary or SES.

Coincidence of pachydermoperiostosis and synovitis, acne, pustulosis, hyperostosis, osteitis syndrome, a causal or casual association?

Pachydermoperiostosis (PDP) is a rare disorder characterized by skin thickening, acropachia, and periostosis. Synovitis, acne, pustulosis, hyperostosis, osteitis (SAPHO) syndrome is also an orphan disease featured by different dermatological and osteoarthritic manifestations. Herein, we report the first case of an adolescent male diagnosed with both PDP and SAPHO syndrome, presenting with digital clubbing, polyarthralgia, ostealgia, pachydermia and acne on his face, chest and back. Furthermore, we distinguish the characteristics of both diseases and explore the potential pathological mechanism for this coexistence in one patient. Further investigations are needed to establish the detailed pathophysiological association of these 2 diseases.

Increased Vitamin A Level is associated with Clinical Improvement in Mild Acne Vulgaris: A Pre-test and Post-test Clinical Trial

AV is a global cutaneous disorder that although is benign, can significantly affect the patient’s quality of life. The pathognomonic feature of the disease is the emergence of comedones. There are four known pathophysiology of AV, increased sebum production, ductal cornification, colonization of the bacteria P. acnesin the pilosebaceous unit, and inflammation. Furthermore, Vitamin A although already a well-established acne treatment that can affect all four of these factors, here are still limited data regarding the quantitative measurement of vitamin A itself in acne vulgaris cases. This study seeks to review the association between vitamin A levels measured quantitatively using ELISA with the outcome of inflamed lesions and comedones prior and after treatment with Tretinoin 0.025% in patients with mild AV. Our studies found that increased level of vitamin A is associated with significant clinical improvements in both inflamed and non-inflamed AV lesions.

A Randomized, Controlled Trial of Trifarotene Plus Doxycycline for Severe Acne Vulgaris

OBJECTIVE

We evaluated the efficacy and safety of trifarotene plus oral doxycycline in acne.

METHODS

This was a randomized (2:1 ratio) 12-week, double-blind study of once-daily trifarotene cream 50µg/g plus enteric-coated doxycycline 120mg (T+D) versus trifarotene vehicle and doxycycline placebo (V+P). Patients were aged 12 years or older with severe facial acne (≥20 inflammatory lesions, 30 to 120 non-inflammatory lesions, and ≤4 nodules). Efficacy outcomes included change from baseline in lesion counts and success (score of 0/1 with ≥2 grade improvement) on investigator global assessment (IGA). Safety was assessed by adverse events and local tolerability.

RESULTS

The study enrolled 133 subjects in the T+D group and 69 subjects in the V+P group. The population was balanced, with an approximately even ratio of adolescent (12-17 years) and adult (≥18 years) subjects. The absolute change in lesion counts from baseline were: -69.1 T+D versus -48.1 V+P for total lesions, -29.4 T+D versus -19.5 V+P for inflammatory lesions, and -39.5 T+D versus -28.2 for non-inflammatory lesions (P<0.0001 for all). Success was achieved by 31.7 percent of subjects in the T+D group versus 15.8 percent in the V+P group (P=0.0107). The safety and tolerability profiles were comparable between the T+D and V+P arms.

CONCLUSION

T+D was demonstrated to be safe and efficacious as a treatment option for patients with severe acne.

The increasing importance of the gut microbiome in acne vulgaris

Acne is a frequently presented dermatological condition brought about by an interplay among inflammation, increased sebum production, hyperkeratinisation, and predominantly Propionibacterium acnes (renamed as Cutibacterium acnes) proliferation, leading to debilitating psychological scars. However, it has been shown that it is the loss of microbial diversity in the skin and the imbalance among C. acnes phylotypes that brings about acne rather than the C. acnes species as a whole. Interestingly, recent evidence suggests that other microorganisms may be implicated, such as the fungi Malassezia and the bacteria Cutibacterium granulosum. A plethora of scientific evidence suggests that the gut microbiome is implicated in the overall health and physiology of the host; studies show that the gut microbiome of acne patients is distinct and depicts less microbial diversity compared to individuals without acne. Herein, using the key terms: acne, C. acnes, IGF-1, sebum, and gut microbiome, we carried out a review of the literature, using Google Scholar and PubMed, and discussed the role of the gut and skin microbiome in relation to acne, as a narrative review. The role of hormones, diet, sebum, and stress in relation to the gut microbiome was also investigated. Therapeutic implications and the use of pre-/postbiotics are also deliberated upon. In this light, future research should investigate the relationship between the gut microbiome and the agreed upon factors of acne pathology, potentially leading to the discovery of novel acne treatments with milder side effects.

Role of Lactium™ in Psychodermatology: The CERTAIN Trial# on Patients with Acne Vulgaris

Stress plays an important role in the causation and aggravation of psychodermatological conditions such as acne vulgaris. Alpha casein hydrolysate (αs1-casein hydrolysate; Lactium) has been shown to decrease serum cortisol levels, reduce stress-related symptoms, and promote relaxation. “This study aimed to compare the efficacy and safety of Lactium™ plus standard care to those of standard of care alone in reducing stress levels and acne severity in patients with acne vulgaris.” The C.E.R.T.A.I.N trial (Name registered with Clinical Trials Registry-India-No. CTRI/2019/01/017172) is a randomized, controlled, multicenter, open-label, two-arm, investigator-initiated clinical trial. A total of 100 patients with moderate-to-severe acne vulgaris were enrolled and randomly assigned to one of the two groups: Lactium™ plus standard care or standard care alone. Stress levels were assessed using serum cortisol levels, Investigator's Global Assessment (IGA) acne severity scale scores, Perceived Stress Scale (PSS) scores, and the Hamilton Anxiety Rating Scale (HAM-A) scores. The Dermatology Life Quality Index (DLQI) was also used to assess the impact of the skin disease on patients' quality of life. At 12 weeks, stress levels were significantly lower in group A (Nixiyax plus standard of care) than that in group B(only standard care), as measured by the change in serum cortisol levels (4.75 ± 4.46 vs. −0.24 ± 5.22). Furthermore, the mean change in PSS scores (3.09 ± 2.04 vs. 0.90 ± 2.76) and HAM-A scores (5.11 ± 1.94 vs. 1.25 ± 3.13) was significant. Patients in both arms had a significant decrease in total, inflammatory, and noninflammatory acne lesions, as well as a significant improvement in DLQI and IGA scores. In patients with moderate-to-severe acne vulgaris, Lactium™ was found to be both safe and well-tolerated. Lactium™ plus standard care is more effective than standard care alone in reducing acne severity through stress reduction.

A prospective, randomized, split-face study of concomitant administration of low-dose oral isotretinoin with 30% salicylic acid chemical peeling for the treatment of acne vulgaris in Asian population

BACKGROUND

Acne vulgaris (AV) is a common dermatosis. For moderate to severe AV, isotretinoin is the first-line treatment. Chemical peeling with supramolecular salicylic acid (SSA) was developed with water solubility and advanced skin penetration properties. In the present study, we investigated the efficacy and safety of oral low-dose isotretinoin combined with 30% SSA chemical peeling.

METHODS

Thirty-three moderate-to-severe acne patients were enrolled and received oral low-dose (0.2-0.4 mg/kg/d) isotretinoin and were then randomly assigned to receive 30% SSA or not on each side of the face with 2-week intervals for four sessions. Photos, the number of lesions, GAGS score, skin indices (melanin, erythema, pore, and texture), hydration, and transepidermal water loss (TEWL) were assessed at 0, 2, 4, 6, and 10 weeks. Side effects, efficacy, and satisfactory rates were recorded.

RESULTS

A total of 29 patients completed the study. Oral isotretinoin combined with SSA decreased response time compared to isotretinoin monotherapy, with significantly improved GAGS score, count of lesions, and efficacy (%) at 4-6 weeks. Skin indices of melanin, erythema, pore, and texture evaluated at week 10 were improved as well. Oral isotretinoin with or without SSA was effective by the lesion clearance; only SSA significantly improved the TEWL. All the side effects were temporary and tolerable, and no adverse effects were observed.

CONCLUSION

Oral low-dose isotretinoin combined with 30% SSA is safe and effective, which advanced the onset of action and improves lesion clearance.

The Prevalence of Polycystic Ovary Syndrome, Its Phenotypes and Cardio-Metabolic Features in a Community Sample of Iranian Population: Tehran Lipid and Glucose Study

Objectives

The aim of the present study was to evaluate the prevalence of polycystic ovary syndrome (PCOS), its phenotypical and cardio-metabolic features in a community sample of the Iranian population in comparison to healthy eumenorrheic, non-hirsute women without polycystic ovaries. The second aim was to assess the cardio-metabolic characteristics of women who suffered from one criteria of PCOS compared to those healthy eumenorrheic, non-hirsute women.

Methods

In this cross-sectional population-based study, a total of 1,960 eligible women, aged (18-45 years) were recruited from the Tehran-Lipid and Glucose-Study participants and were classified as the three groups of (i) women with PCOS by the Rotterdam criteria, (ii) non-PCOS women with one criteria of PCOS and (iii) healthy eumenorrheic, non-hirsute women without polycystic ovaries morphology (PCOM) as the control group. Further PCOS women were extended to four phenotypes of hyperandrogenism, oligo-anovulation, polycystic ovaries (phenotype A), hyperandrogenism, oligo/anovulation (phenotype B), hyperandrogenism, polycystic ovaries (phenotype C) and oligo-anovulation, polycystic ovaries (phenotype D). Cardio-metabolic profiles and the prevalence of comorbidities of metabolic syndrome (MetS) and lipid abnormalities were compared among these groups linear, and the median regression models adjusted for age and body mass index.

Results

The prevalence of PCOS according to the diagnostic criteria of the NIH, Rotterdam and AE-PCOS Society were 13.6, 19.4, and 17.8, respectively. Among those who met the Rotterdam criteria, 23.9, 46.3, 21.6, and 8.2% had phenotypes A, B, C, and D, respectively. Among the remaining 1,580 women who did not fulfil the PCOS criteria, 108 (6.8%) suffered from only oligo/anovulation, 332 (21%) only hyperandrogenism/hyperandrogenemia, 159 (16.2%) only PCOM in ultrasound and 981 (62%) were healthy eumenorrheic, non-hirsute women without PCOM. The study revealed that some adiposity indices and lipid abnormalities in PCOS phenotypes with hyperandrogenism (A, B, and C) were worse than in healthy women. By contrast, women with phenotype D did not differ from the healthy ones in terms of adiposity and lipid abnormalities. However, the respective values for other cardio-metabolic profiles and MetS rates in different phenotypes of PCOS were similar to the healthy women. Only the prevalence of MetS in phenotype A was significantly higher than in the healthy women. There were no statistically significant differences between participants with one criteria of PCOS and healthy counterparts in terms of most adiposity indexes, cardio-metabolic factors, and comorbidity of MetS and its components. However, women with hyperandrogenism had a significantly higher level of the waist to height ratio (WHtR) and hypertriglyceridemia than their healthy counterparts.

Conclusion

PCOS, mainly classical phenotypes A and B, are common among Iranian women of reproductive age. Women with PCOS who had androgen excess exhibited the worst lipid profile, and those who had full three criteria of the syndrome exhibited the higher rate of MetS. However, women with only ovulatory dysfunction and only PCOM had similar cardio-metabolic characteristics, compared to healthy subjects. These data suggest that routine screening for metabolic disturbances may be needed in the prevention of cardio-metabolic disorders in patients with more serious phenotypes of PCOS.

Proteomic Analysis of the Antibacterial Effect of Improved Dian Dao San against Propionibacterium acnes

Propionibacterium acnes (P. acnes) is a major pathogen of acne vulgaris. The traditional Chinese medicine (TCM) compound prescription, Dian Dao San (DDS), is effective for treating P. acnes. Previous clinical work by our team demonstrated that improved Dian Dao San (IDDS) has better antibacterial effects. However, the mechanism of IDDS inhibition of P. acnes is still unknown. Hence, the isobaric tags for relative and absolute quantitation (iTRAQ) technology was applied to explore the antibacterial mechanism of IDDS against P. acnes. Our results suggested that the antibacterial mechanism of IDDS was related to the glycolytic pathway. gap, pgk, and tpiA enzymes were found to be potential target proteins in the bacterial glycolytic pathway as an antibacterial mechanism of inhibition. In addition, SEM and TEM analyses revealed that IDDS may destruct bacterial plasma membrane and cell wall. The results provide a reliable, direct, and scientific theoretical basis for wide application of IDDS.

Adult female acne: Clinical and therapeutic particularities (Review)

Acne is a chronic inflammatory condition affecting the pilosebaceous unit that was traditionally viewed as a disease of the adolescence. However, over the past several years, an increasing number of adult women have been reported to suffer from this condition. The prevalence of adult female acne ranges between 12 and 54%. Two clinical types can be distinguished in this population, a 'retentional' and an 'inflammatory' type, which usually tend to overlap. In terms of evolution, three main subtypes can be identified: Persistent acne, which is the most frequent subtype, late-onset acne and recurrent acne. This type of acne is mainly mild-to-moderate in severity and may be refractory to conventional treatment. The etiopathogenesis is complex and has yet to be fully elucidated. It appears to involve an interaction among genetic predisposition, hormonal factors, and chronic activation of the innate immune system overlapping with external factors, such as daily stress, Western-type diet, use of tobacco and cosmetics. The treatment may be challenging and a holistic approach is required, with special attention to the individual needs and particularities of adult women. Both topical and systemic treatments are available, with hormonal therapies being of special value in this population. The aim of the present article was to provide up-to-date, evidence-based information on the clinical presentation, etiopathogenesis and treatment of adult female acne.

Low dose oral isotretinoin for the treatment of adult patients with mild-to-moderate acne vulgaris: Systematic review and meta-analysis

Acne vulgaris is one of the most common dermatologic complaints. Recently, isotretinoin has been used as an off-label indication for the treatment of mild-to-moderate grades of acne not responding to conventional treatment. Its conventional recommended dose is 0.5-1.0 mg/kg per day to the cumulative dose of 120-150 mg/kg.

OBJECTIVES

To qualify the state of evidence and analyze the efficacy of the low daily dose and the pulsed doses of isotretinoin in treating mild-to-moderate acne patients with regards to response and relapse rates.

METHOD

Systematic review and meta-analysis using an electronic literature search were performed. 320 potentially relevant articles were included and reviewed.

RESULTS

The level of evidence is moderate to low as conducted by the GRADE quality of evidence assessment. The pooled statistical estimate for response to treatment in the group comparing low daily doses with conventional dose showed an overall benefit for conventional dose. On the other hand, pooled data from the group comparing the low daily dose with the pulsed doses yielded an overall beneficial effect from using the low daily dose compared with the pulsed doses on achieving the response.

CONCLUSIONS

Given all of the available studies, the quality of evidence is low. It appears that conventional dose isotretinoin improves the odds of prolonged remission in adults with mild-to-moderate acne vulgaris compared to the low doses.

The Effectiveness of Autologous Serum and Single-dose Oral Doxycycline in the Treatment of Acne Vulgaris: A Pilot Clinical Trial

Introduction: Acne vulgaris is a chronic inflammatory disease that occurs with various factors, both intrinsic and extrinsic. Treatment of choice can vary from topical, systemic or a combination of both depending on the degree of severity. Recently, treatment using products from human blood has been widely studied, including in the field of dermatology as it has a unique composition. Objective: to assess the effectiveness of autologous serum and single-dose oral doxycycline in the treatment of acne vulgaris Methods: this clinical trial compared two groups which received autologous serum only and autologous serum combined with single dose of oral 200 mg doxycycline, respectively. Photographic pictures and number of lesions (blackheads, papules, pustules) were compared before and after application using Wilcoxon test. Results: A total of 20 participants participated in this study. Both treatment groups showed significant decrease in lesion count (p <0.01). However, the group which received autologous serum and single dose of oral doxycycline showed superior improvement of inflammatory acne lesions. Conclusion: autologous serum and single dose of oral doxycycline was superior to autologous serum only in the treatment acne lesions. Keywords: Acne Vulgaris, Doxycycline, Autologous Serum

The comparison of demographics and comorbidities of female pattern hair loss according to the clinical subtype and stage

BACKGROUND

Previous literature regarding the frequencies of each subtype of female pattern hair loss is contradictory and the subtypes have not been compared to each other in terms of their epidemiologic characteristics and relationships with comorbid diseases.

OBJECTIVES

The aims of this study are to determine the frequency and the relationship with comorbidities for each subtype, and to determine the relationship of clinical stage with age and comorbid diseases.

METHODS

This is a prospective cross-sectional study involving patients with a definitive diagnosis of female pattern hair loss. The age, age at the time of diagnosis, family history for androgenetic alopecia, clinical subtype, clinical stage, and comorbid conditions were noted for each patient. SPSS version 21 (IBM SPSS) was used for statistical analysis.

RESULTS

Advanced stages of female pattern hair loss are related to increased age, menopausal state, and hypertension. Acne vulgaris is more prevalent in earlier stages. Hirsutism and acne vulgaris are more commonly encountered in the Ludwig and Hamilton subtypes. Hypertension is more frequent in Ludwig subtype.

LIMITATIONS

The confounding effect of age on the relationship between clinical subtype and comorbid diseases.

CONCLUSION

The relationship between comorbid diseases and stage in specific subtypes can guide us to the diagnosis of undiagnosed comorbid diseases.

Management of Acne Vulgaris: A Review

IMPORTANCE

Acne vulgaris is an inflammatory disease of the pilosebaceous unit of the skin that primarily involves the face and trunk and affects approximately 9% of the population worldwide (approximately 85% of individuals aged 12-24 years, and approximately 50% of patients aged 20-29 years). Acne vulgaris can cause permanent physical scarring, negatively affect quality of life and self-image, and has been associated with increased rates of anxiety, depression, and suicidal ideation.

OBSERVATIONS

Acne vulgaris is classified based on patient age, lesion morphology (comedonal, inflammatory, mixed, nodulocystic), distribution (location on face, trunk, or both), and severity (extent, presence or absence of scarring, postinflammatory erythema, or hyperpigmentation). Although most acne does not require specific medical evaluation, medical workup is sometimes warranted. Topical therapies such as retinoids (eg, tretinoin, adapalene), benzoyl peroxide, azelaic acid, and/or combinations of topical agents are first-line treatments. When prescribed as a single therapy in a randomized trial of 207 patients, treatment with tretinoin 0.025% gel reduced acne lesion counts at 12 weeks by 63% compared with baseline. Combinations of topical agents with systemic agents (oral antibiotics such as doxycycline and minocycline, hormonal therapies such as combination oral contraception [COC] or spironolactone, or isotretinoin) are recommended for more severe disease. In a meta-analysis of 32 randomized clinical trials, COC was associated with reductions in inflammatory lesions by 62%, placebo was associated with a 26% reduction, and oral antibiotics were associated with a 58% reduction at 6-month follow-up. Isotretinoin is approved by the US Food and Drug Administration for treating severe recalcitrant nodular acne but is often used to treat resistant or persistent moderate to severe acne, as well as acne that produces scarring or significant psychosocial distress.

CONCLUSIONS AND RELEVANCE

Acne vulgaris affects approximately 9% of the population worldwide and approximately 85% of those aged 12 to 24 years. First-line therapies are topical retinoids, benzoyl peroxide, azelaic acid, or combinations of topicals. For more severe disease, oral antibiotics such as doxycycline or minocycline, hormonal therapies such as combination oral conceptive agents or spironolactone, or isotretinoin are most effective.

Red Seaweed-Derived Compounds as a Potential New Approach for Acne Vulgaris Care

Acne vulgaris (AV) is a chronic skin disease of the pilosebaceous unit affecting both adolescents and adults. Its pathophysiology includes processes of inflammation, increased keratinization, sebum production, hormonal dysregulation, and bacterial Cutibacterium acnes proliferation. Common AV has been treated with antibiotics since the 1960s, but strain resistance has emerged and is of paramount concern. Macroalgae are known producers of substances with bioactive properties, including anti-viral, antibacterial, antioxidant, and anti-inflammatory properties, among several others. In particular, red algae are rich in bioactive compounds such as polysaccharides, phenolic compounds, lipids, sterols, alkaloids, and terpenoids, conferring them antioxidant, antimicrobial, and anti-inflammatory activities, among others. Thus, the exploration of compounds from marine resources can be an appealing approach to discover new treatment options against AV. The aim of this work is to provide an overview of the current knowledge of the potentialities of red macroalgae in the treatment of AV by reviewing the main therapeutic targets of this disease, and then the existence of compounds or extracts with bioactive properties against them.

Transcriptomics Analysis Indicates Trifarotene Reverses Acne-Related Gene Expression Changes

Background and Objectives: Trifarotene is a topical retinoid selective for retinoic acid receptor gamma that was recently approved for treatment of acne vulgaris. We performed a gene expression analysis to identify the molecular and cellular impact of trifarotene treatment on acne papules. Methods: In this open-label prospective study, subjects with moderate inflammatory acne of the back were treated with trifarotene 0.005% or vehicle cream on dedicated areas for 27 days, and 4 biopsies were collected from each subject (1 from skin without a visible acne lesion and three at the site of an acne papule: one baseline, one after vehicle treatment, and one after trifarotene treatment). Large scale gene expression profiling of the biopsies was performed using Affymetrix technology, treatment-specific gene expression profiles were generated using statistical modeling, and pathway analysis was performed. Using single-cell RNAseq data, in silico deconvolution of transcriptomics data was performed to identify cellular signatures. Results: We discovered a unique set of 67 genes modulated by trifarotene that are primarily involved in cellular migration, inflammation, and extracellular matrix reorganization. Changes in cellular expression were similar in both trifarotene-treated and spontaneously-resolving lesions. However, only trifarotene treatment impacted SPP1⁺ macrophages, a subset of highly proliferative macrophages recently identified in fibrotic tissue. Conclusions: These results show that trifarotene has a novel action in acne treatment by affecting epidermal and immune components of acne pathogenesis.

Long-term effect of azelaic acid peel on sebum production in acne

Seborrhea and the associated oily skin are undoubtedly the problem of women and men around the world. The pathogenesis of acne vulgaris involves excessive activity of sebaceous glands, as well as disturbances in the composition of sebum. The aim of the study was to assess the severity of seborrhea in a group of acne vulgaris patients and to determine the effect of a 20% azelaic acid solution on the activity of sebaceous glands. Twenty seven women, aged 19-25 years, underwent a series of six treatments with the application of a 20% solution of azelaic acid to the face. The mean values of sebum level showed a decreasing tendency. On the forehead, the results were as follows-195.5 before the treatment and 162.7 2 weeks after the last treatment. Measurements of the right cheek decreased from 175.3 to 141.3 The measurements taken 3 months after the study were 151.3 on the forehead and 138.9 on the cheek. Similarly, the values determining the total number of acne lesions and the severity of the disease according to the IGA scale also changed significantly. Chemical peel with 20% azelaic acid shows long-term sebostatic action, which inhibits the formation of new acne lesions.

Acupuncture: A therapeutic approach against acne

Acne is a common but chronic skin disease that influence large population especially juvenile. Acne can continue, begin, or grow into severe form in adult age, affecting face, back, and chest. It may be a serious issue if not cared or treated timely. Even if acne got treated it leaves a persistent scar, which is difficult to alleviate. These acne lesions are long-lasting and result in significant impact on mental and physical health of an individual. There are four mechanisms that are involved in acne lesion formation. However, the accurate series of events of the interaction among the factors in acne pathogenesis is still unsettled. Pubescent acne is due to increase hormone levels, when in fact adult acne is due to fluctuation in hormone levels. There are various approaches for the treatment of acne, including oral medications, creams or gels, acupuncture. Traditional Chinese Medicine stated acne as a infection that is associated with the pathogenic influence of damp heat and heat on specific meridians. As an ancient and integral part of Chinese medicine acupuncture therapy is employed in the treatment of many diseases including acne. It functions by ameliorating the deep-rooted mechanisms playing crucial role in acne development. In this review, we have explained the acne causes, pathogenesis, and its available treatment options. Additionally, we also discussed the acupuncture therapy methods, devices, different techniques. and its mechanism of action in treating acne. Furthermore, clinical trials studies motivated us to highlight the scope of acupuncture in the growing system of medicine.

Assessment of Anxiety and Depression in Patients with Acne Vulgaris in Medina: A Case-Control Study

Purpose

Acne vulgaris is a common dermatological disease in adolescents that show high prevalence rates of anxiety and depression that may lead to consequences that affect quality of life. This study aimed to assess and compare anxiety and depression in patients with acne and a control group and to determine their correlation with other demographic data.

Patients and Methods

This was a case-control study conducted in 2019 for 3 months at the derma-tology department of Ohud Hospital and two other private clinics in the Medina region of Saudi Arabia. For this study, 296 consecutive patients in the age group of 12 to 60 years who were diagnosed as having acne vulgaris were enrolled and matched with a control group. Data were collected through a self-administered questionnaire, including sociodemographic data and Hospital Anxiety and Depression Scale scores.

Results

We found no significant differences between the two groups regarding sex, age group, nationality, and educational level, but found a significant difference in marital status (p < 0.001). Most (62.5%) of the acne cases were moderate in severity. The overall anxiety score in the acne group was 7.68 ± 4.90, with a significant difference with the control group (p = 0.031), whereas the anxiety level and depression score showed no significant difference (p = 0.082 and p = 0.656, respectively). Moreover, a strong correlation was found between anxiety and depression in the acne group (r = 0.732, p < 0.001).

Conclusion

A positive correlation was found between the anxiety and depression scores in the patients with acne, which was not related to age group or educational level. However, the anxiety scores of the patients with acne showed a significant relationship with sex.

Nanotechnology-based formulations toward the improved topical delivery of anti-acne active ingredients

Introduction: Acne vulgaris is a chronic inflammatory skin disorder that affects an extremely concerning percentage of teenagers (ca. 85%), gathering serious negative impacts on the social life and psychological well-being of individuals. Conventional topical formulations for acne show low tolerability and side effects, such as skin irritation, leading to a decrease in the user's adherence to therapy. Nanotechnology-based formulations were developed as new strategies for topical acne management, particularly to overcome the difficulties associated with conventional treatments.Areas covered: This paper presents a critical analysis of reviewed nanosized anti-acne technological strategies, strongly supporting controlled active ingredient release, improved skin permeation, and lower skin irritation. An updated regulatory framework, considering the promising applications in nanomedicine, and the toxicity of these nanosystems are also addressed.Expert opinion: Nanosystems evidence several advantages, attending to the possibility of controlled active ingredient release, better skin permeation, and lower skin irritation. However, novel nanotechnological strategies for acne treatment and care can lead to new side effects, but also environmental nano pollution. Little is known about the toxicology of these nanotechnology-based formulations, therefore, as future trends, more studies should be conducted to assure the consumers' health and environmental safety.

Clascoterone: a new topical anti-androgen for acne management

Clascoterone is an androgen receptor inhibitor which has been approved by the United States Food and Drug Administration for the topical treatment of acne vulgaris in patients 12 years of age and older. It competes with androgens, especially dihydrotestosterone, for androgen-receptor binding and limits their binding, thus inhibiting downstream signaling of pathways involved in the pathogenesis of acne. It inhibits androgen receptor-regulated gene transcription, and antagonizes lipid and inflammatory cytokine production in a dose-dependent manner in human primary sebocytes. Clascoterone is commercially available as 1% (10 mg/g) cream. Adverse effects of topical clascoterone are mild and infrequent, and are mostly limited to local skin reactions. Long-term safety studies have shown an absence of systemic antiandrogenic effects like reduced libido or feminization in male participants. Clascoterone seems a promising topical drug with a novel mechanism of action that could be added to the armamentarium of therapies for acne.
