Rhizoma Paridis saponins attenuate Gram-negative bacteria-induced inflammatory acne by binding to KEAP1 and modulating Nrf2 and MAPK pathways.

Acne vulgaris represents a chronic inflammatory condition, the pathogenesis of which is closely associated with the altered skin microbiome. Recent studies have implicated a profound role of Gram-negative bacteria in acne development, but there is a lack of antiacne agents targeting these bacteria. Polyphyllins are major components of Rhizoma Paridis with great anti-inflammatory potential. In this study, we aimed to evaluate the antiacne effects and the underlying mechanisms of PPH and a PPH-enriched Rhizoma Paridis extract (RPE) in treating the Gram-negative bacteria-induced acne. PPH and RPE treatments significantly suppressed the mRNA and protein expressions of interleukin (IL)-1ß and IL-6 in lipopolysaccharide (LPS)-induced RAW 264.7 and HaCaT cells, along with the intracellular reactive oxygen species (ROS) generation. Furthermore, PPH and RPE inhibited the nuclear translocation of nuclear factor kappa-B (NF-κB) P65 in LPS-induced RAW 264.7 cells. Based on molecular docking, PPH could bind to kelch-like ECH-associated protein 1 (KEAP1) protein. PPH and RPE treatments could activate nuclear factor erythroid 2-related factor 2 (NRF2) and upregulate haem oxygenase-1 (HO-1). Moreover, RPE suppressed the mitogen-activated protein kinase (MAPK) pathway. Therefore, PPH-enriched RPE showed anti-inflammatory and antioxidative effects in vitro, which is promising for alternative antiacne therapeutic.

Haplotype analysis and linkage disequilibrium of ApoB gene polymorphisms and its relationship with hyperlipidemia in patients with acne vulgaris.

BACKGROUND: Acne vulgaris (AV) is a chronic, multifactorial inflammatory disease of the pilosebaceous unit brought on by hormonal imbalance, excessive sebum production, follicular hyperkeratinization, inflammation and Cutibacterium acne. Acne patients are characterized by alteration of the lipid profile. Apolipoprotein B gene (ApoB) plays an essential role in lipoprotein biosynthesis and multiple single-nucleotide polymorphisms (SNPs) in ApoB are associated with dyslipidemia. AIM: The aim of this study was to estimate the alteration of lipid profiles in AV, determine the genetic association with lipid profile alteration by studying the ApoB gene polymorphisms, and to identify the exact haplotypes associated with acne and lipid profile alteration. SUBJECTS AND METHODS: In a case-control study consisting of 63 non-obese acne patients and 43 healthy controls, all participants underwent biochemical, anthropological assessments, and genetic analysis for ApoB polymorphisms. RESULT: Our results indicate that serum ApoB and the lipid profile were higher in acne patients compared with healthy subject. The most common haplotypes in acne patients were rs562338 A/rs17240441 I/c.12669 A/rs1042034 G, whereas the most common haplotypes in healthy subjects were rs562338 G/rs17240441 D/c.12669 A/rs1042034 G. Patients with mild acne had higher serum ApoB levels p = 0.005. Also, the low-density lipoprotein cholesterol (LDL-C) level was higher in mild acne compared with other acne groups, with a highly significant variation of p ≤ 0.001. CONCLUSION: We found a significant variation between the acne group and healthy controls in serum ApoB, triglycerides, total cholesterol and LDL-C. The most common haplotypes in acne patients are rs562338 A/, rs17240441 I/, c.12669 A/ and rs1042034 G, and there is a linkage disequilibrium between the four selected SNPs.

Applications of nitric oxide-releasing nanomaterials in dermatology: Skin infections and wound healing.

Nitric oxide (NO) is produced in most cells in the skin and is an important regulator of essential cutaneous functions, including responses to UV irradiation, microbial defense, wound healing, melanogenesis and epidermal permeability barrier homeostasis. Harnessing the physiological activities of NO for therapeutic use is difficult because the molecule is highly reactive and unstable. A variety of exogenous NO delivery platforms have been developed and evaluated; however, they have limited clinical applications in dermatology due to instability and poor cutaneous penetration. NO-releasing nanomaterials overcome these limitations, providing targeted tissue delivery, and sustained and controlled NO release. This review provides a comprehensive and up-to-date evaluation of the use of NO-releasing nanomaterials in dermatology for the treatment of skin and soft tissue infections and wound healing.

The epidemiology of acne vulgaris in a multiethnic adolescent population from Rotterdam, the Netherlands: A cross-sectional study.

BACKGROUND: Although acne is a prevalent multifactorial inflammatory skin condition, few studies were performed in multiethnic populations. OBJECTIVES: To study the prevalence and determinants of acne in a multiethnic study at the start of puberty. METHODS: This cross-sectional study is embedded in Generation R, a population-based prospective study from Rotterdam, the Netherlands. Three-dimensional facial photos at the center visit in 2016-2019 (of ∼13-year-olds) were used to grade acne severity using the Global Evaluation of the Acne Severity (GEA). Analyses were stratified by biological sex and explored through chi-square tests and multivariable ordinal logistic regression. RESULTS: A total of 4561 children (51% girls) with a median age of 13.5 (IQR 13.3-13.6) were included. The visible acne prevalence (GEA 2-5) for girls vs boys was 62% vs 45% and moderate-to-severe acne (GEA 3-5) 14% vs 9%. Higher puberty stages (adjusted odds ratios: 1.38 [1.20-1.59] and 2.16 [1.86-2.51] for girls and boys, respectively) and darker skin colors V and VI (adjusted odds ratios: 1.90 [1.17-3.08] and 2.43 [1.67-3.56]) were associated with more severe acne in both sexes, and being overweight in boys (adjusted odds ratio: 1.58 [1.15-2.17]). LIMITATIONS: Cross-sectional design. CONCLUSIONS: Acne prevalence was high at the age of 13 years and was associated with advanced puberty, darker skin color, and weight status.

Photobiomodulation CME part II: Clinical applications in dermatology.

Photobiomodulation (PBM) is an emerging treatment modality in dermatology with increasing office and home-based use. PBM is the use of various light sources in the red light (620-700 nm) and near-infrared (700-1440 nm) spectrum as a form of light therapy. PBM is often administered through low-level lasers or light-emitting diodes. Studies show that PBM can be used effectively to treat conditions secondary to cancer therapies, alopecia, ulcers, herpes simplex virus, acne, skin rejuvenation, wounds, and scars. PBM offers patients many benefits compared to other treatments. It is noninvasive, cost-effective, convenient for patients, and offers a favorable safety profile. PBM can be used as an alternative or adjuvant to other treatment modalities including pharmacotherapy. It is important for dermatologists to gain a better clinical understanding of PBM for in-office administration and to counsel patients on proper application for home-use devices to best manage safety and expectations as this technology develops. PBM wavelengths can induce varied biological effects in diverse skin types, races, and ethnicities; therefore, it is also important for dermatologists to properly counsel their skin of color patients who undergo PBM treatments. Future clinical trials are necessary to produce standardized recommendations across conditions and skin types.

Guidelines of care for the management of acne vulgaris.

BACKGROUND: Acne vulgaris commonly affects adults, adolescents, and preadolescents aged 9 years or older. OBJECTIVE: The objective of this study was to provide evidence-based recommendations for the management of acne. METHODS: A work group conducted a systematic review and applied the Grading of Recommendations, Assessment, Development, and Evaluation approach for assessing the certainty of evidence and formulating and grading recommendations. RESULTS: This guideline presents 18 evidence-based recommendations and 5 good practice statements. Strong recommendations are made for benzoyl peroxide, topical retinoids, topical antibiotics, and oral doxycycline. Oral isotretinoin is strongly recommended for acne that is severe, causing psychosocial burden or scarring, or failing standard oral or topical therapy. Conditional recommendations are made for topical clascoterone, salicylic acid, and azelaic acid, as well as for oral minocycline, sarecycline, combined oral contraceptive pills, and spironolactone. Combining topical therapies with multiple mechanisms of action, limiting systemic antibiotic use, combining systemic antibiotics with topical therapies, and adding intralesional corticosteroid injections for larger acne lesions are recommended as good practice statements. LIMITATIONS: Analysis is based on the best available evidence at the time of the systematic review. CONCLUSIONS: These guidelines provide evidence-based recommendations for the management of acne vulgaris.

In severe acne vulgaris, TNF-α gene variants are connected to increased TNF-α gene expression and insulin resistance.

BACKGROUND: Acne vulgaris (AV) is a chronic inflammatory skin condition affecting the pilosebaceous unit, commonly presenting as comedones, papules, pustules, or nodules on the face, upper limbs, torso, and back, with comedones formation being the primary pathology leading to disfiguring inflammation, hyperpigmentation, scarring, and psychological impact. AIM: The purpose of this study was to investigate the significance of two genetic variants in the promoter region of the tumor necrosis factor-alpha (TNF-α) gene and their association with insulin resistance (IR) in acne patients. To understand how these variants contribute to AV and its associated IR. SUBJECTS AND METHODS: An analytical cross-sectional study with a case-control design and research evaluation was carried out on 87 AV patients and 73 healthy volunteers. The medical histories of both groups were obtained, as well as the severity and duration of inflammation among acne sufferers, as well as demographic data. Biochemical analysis was performed on both sets of participants, including fasting blood glucose levels, insulin levels while fasting, IR, and serum TNF-α. PCR-RFLP analysis identified -863 G > A (rs1800630) and -308 G > A (rs1800629) variations, and real-time PCR analysis evaluated TNF-α gene expression in both patients and healthy people. RESULTS: Acne patients exhibited significantly higher levels of IR, fasting glucose, fasting insulin, serum TNF-α, and TNF-α folding change, when compared to healthy controls. The co-dominant model for -863 G > A and -308 G > A variants exhibited significant variations between the two groups. Severe acne patients who had the A/A genotype for -308 variants exhibited higher levels of IR, serum TNF-α, and TNF-α folding change. Highly significant positive linear correlation between IR, serum TNF-α, and TNF-α folding change in severe AV. CONCLUSION: There is a correlation between AV, especially severe acne, and the -863 G > A and -308 G > A polymorphism, which influences TNF-α gene expression and serum TNF-α levels.

Poly­d,l­lactic acid­enhanced atrophic scar treatment via transdermal microjet drug delivery in Asians.

BACKGROUND: Acne vulgaris often results in permanent scars, with atrophic scars being the most common type and posing a significant therapeutic challenge due to their prevalence and impact on patients' quality of life. Various treatment options exist, including the use of poly-d,l-lactic acid delivered via different methods. OBJECTIVE: This study aimed to assess the efficacy and safety of poly-d,l-lactic acid delivered via laser-assisted needle-free microjet injection for treating atrophic scars. METHODS: Five Korean participants with atrophic facial scars were recruited. Poly-d,l-lactic acid solution was administered via the Mirajet system in five sessions, with clinical assessments conducted at baseline, before each session, and at 12-week and 22-week follow-ups. Outcome measures included the Global Aesthetic Improvement Scale and patient satisfaction scores. RESULTS: Positive results were observed at the 12-week and 22-week follow-ups, with high patient satisfaction and improvements in atrophic scars and skin texture. Mild discomfort and transient side effects were reported, with no adverse events observed during the follow-up period. CONCLUSION: Poly-d,l-lactic acid delivered by a laser-assisted needle-free microjet injector was judged to be effective for improving atrophic the facial area. Further research, particularly through randomized controlled trials, is needed to validate these findings and assess the longer-term safety and sustainability of outcomes.

Causal relationship between inflammatory skin diseases and breast cancer: A bidirectional Mendelian randomization study.

INTRODUCTION: Prior research has explored the relationship between inflammatory skin disorders and breast cancer (BC), yet the causality of this association remains uncertain. METHODS: Utilizing a bidirectional two-sample Mendelian randomization (MR) approach, this study aimed to elucidate the causal dynamics between various inflammatory skin conditions-namely acne, atopic dermatitis, psoriasis vulgaris, urticaria, and rosacea-and BC. Genetic variants implicated in these disorders were sourced from comprehensive genome-wide association studies representative of European ancestry. In the forward MR, BC was posited as the exposure, while the reverse MR treated each inflammatory skin disease as the exposure. A suite of analytical methodologies, including random effects inverse variance weighted (IVW), weighted median (WME), and MR-Egger, were employed to probe the causative links between inflammatory skin diseases and BC. Sensitivity analyses, alongside evaluations for heterogeneity and pleiotropy, were conducted to substantiate the findings. RESULTS: The MR analysis revealed an increased risk of acne associated with BC (IVW: OR = 1.063, 95% CI = 1.011-1.117, p = 0.016), while noting a decreased risk of atopic dermatitis (AD) in BC patients (IVW: OR = 0.941, 95% CI = 0.886-0.999, p = 0.047). No significant associations were observed between BC and psoriasis vulgaris, urticaria, or rosacea. Conversely, reverse MR analyses detected no effect of BC on the incidence of inflammatory skin diseases. The absence of pleiotropy and the consistency of these outcomes strengthen the study's conclusions. CONCLUSION: Findings indicate an elevated incidence of acne and a reduced incidence of AD in individuals with BC within the European population.

Long-term efficacy and safety of nonablative monopolar radiofrequency in the treatment of moderate to severe acne vulgaris.

BACKGROUND: Acne vulgaris (AV) is a prevalent skin condition known for its potential to cause scarring and psychological distress, often leading to diminished self-esteem. While topical and oral treatments are commonly prescribed, some patients experience treatment failure, adverse effects, or contraindications to conventional therapies. In response to these challenges, laser and energy-based device therapies have emerged as promising alternatives for individuals who fall into these categories, showing considerable potential in the treatment of AV. OBJECTIVE: This study aimed to evaluate the long-term efficacy and safety of a nonablative monopolar radiofrequency (NMRF) in treatment of moderate to severe AV. METHODS: Twenty-four patients with moderate to severe AV underwent a series of two NMRF treatment sessions, spaced 4 weeks apart. To evaluate treatment outcomes, live in-person lesion counts and measurements of pore size and volume, and sebum production were quantified using Antera® 3D imaging system, and Sebumeter®, respectively. Patients' self-assessment data regarding degree of improvement and facial oiliness were gathered. Dermatology life quality index (DLQI) questionnaire was utilized to assess the impact of AV on their quality of life. All objective and subjective evaluations were conducted at the baseline, 1 month after the first treatment, and during follow-up visits 1, 3, and 6 months after the last treatment sessions. Adverse effects were also recorded during each visit. RESULTS: Twenty out of the 24 subjects completed the study protocol. The mean inflammatory lesion counts significantly reduced by 42.86% and 45.71% from the baseline at 3 (p = 0.027) and 6 months (p = 0.032) after the second treatment. Sebum excretion likewise significantly decreased from baseline by 11.62% (p = 0.012), 13.37% (p < 0.001), and 21.51% (p = 0.004), 1 month after the first treatment, 1 and 6 months after the second treatment, respectively. The pore volume continued to decrease by 35% (p = 0.003) and 41.5% (p < 0.001) at 1 and 6 months following the final treatment, respectively. The DLQI significantly decreased from 10.00 (interquartile range [IQR]: 6.50-15.00) to 2.00 (IQR: 1.00-4.75), corresponding to 80% improvement of the index, 1 month after the last treatment and was sustained up to the last follow-up visit. Patients' self-assessments on degree of improvement and facial oiliness also significantly improved following NMRF treatments. The treatments were well-tolerated without significant adverse effects. CONCLUSION: NMRF appears to be an effective and safe treatment for inflammatory AV, with therapeutic outcomes persisting up to 6 months after two treatment sessions.

The Acne Education Project: An educational initiative to improve acne health literacy and promote help-seeking behavior in young adolescents.

BACKGROUND: Acne vulgaris is an inflammatory skin condition that is associated with poor acne health literacy. Diminished acne health literacy leads to delays in the access of health care, resulting in mismanagement, disfigurement, and psychosocial morbidity. This study evaluates the potential role of early acne education in young adolescent populations to improve acne health literacy and facilitate help-seeking behavior. METHODS: The Acne Education Project is a Canadian medical student-led initiative founded to create evidence-based resources to increase acne health literacy. A 45-min interactive Zoom presentation on acne was created and delivered to 2292 students ages 9-13 in British Columbia, Canada. A quality improvement survey was administered pre-intervention, immediate post-intervention, and 1-month post-intervention to evaluate baseline acne knowledge and knowledge retention to guide presentation and resource development. RESULTS: Responses from 676 unique individuals were collected. Analysis using linear mixed-effects models demonstrated that respondents were significantly more confident in their general knowledge of acne, strategies to prevent acne, identification of psychosocial sequelae of acne, and more willing to seek help immediately post-intervention (p < .001). Differences in scores were not fully preserved in magnitude at the 1-month post-intervention assessment. However, students still scored significantly higher in all categories compared to the pre-intervention baseline (p < .001). CONCLUSION: Our findings suggest that early acne education can improve acne health literacy and promote help-seeking behavior. Given the potential long-term implications, further research is needed to explore the long-term impact of early acne education and the benefit of integrating acne education into the public education curriculum in Canada.

Topical Silymarin Cream as a Novel Therapy Versus Salicylic Acid Peels in Acne Vulgaris: A Split-Face Clinical Trial.

BACKGROUND: Acne vulgaris is a common dermatological condition that greatly impacts patients' self-confidence. Ongoing research is conducted to explore new treatment modalities. Silymarin owns special characteristics that qualify it as a possible treatment for acne vulgaris. OBJECTIVE: We evaluated the efficacy and safety of silymarin cream as a new therapeutic option against salicylic acid peels in the treatment of mild to moderate acne vulgaris. METHODS: A split-face, comparative, Quasi-experimental clinical trial included 30 patients with acne vulgaris. Salicylic acid 30% peels were applied as an office procedure to one half of the face every 2 weeks for 3 months. Topical silymarin 1.4% cream was prescribed as a home treatment, twice daily, to the other half of the face for 3 months. The results were evaluated using the Global Acne Grading System (GAGS), photographic evaluation, and patient self-assessment scale. The adverse effects during treatment were recorded. The sample size was calculated by Stata/IC 16.1. RESULTS: After treatment, a significant reduction of GAGS was noted on both sides of the face, with an insignificant difference between both treatments. The comparative photographic evaluation and patient self-assessment scale were also insignificant. Hyperpigmentation was recorded in 2 cases on the salicylic acid-treated side. No side effects for silymarin cream were observed. CONCLUSION: Topical silymarin cream 1.4% showed comparable results to Salicylic acid 30% peels. It can be considered a promising safe treatment modality for mild to moderate acne vulgaris.

Recent advances in the treatment of acne using radiofrequency techniques.

Acne is a long-lasting inflammatory skin condition that impacts the sebaceous units of the hair follicles, affecting around 85-90% of the population. Due to the potential for permanent facial scarring and negative social consequences, as well as the limitations of conventional medications like drug resistance and difficulties following treatment plans, it's crucial to investigate non-pharmacological options for treating acne, among which radiofrequency(RF) shows distinct superiority. To assess the impact of RF in the management of acne vulgaris, we conducted a thorough examination of scientific literature (including clinical trials and scientific reviews) through electronic databases like MEDLINE and PubMed. Our analysis indicates that RF could be a viable substitute for acne treatment due to its notable effectiveness and minimal adverse effects.

Microchanneling and ultrasonic delivery of gold and platinum nanoparticles for selective photothermolysis of sebaceous follicles in the treatment of acne: a pilot study using porcine skin.

PURPOSE: Several treatment options for acne vulgaris are limited by their associated adverse effects. An innovative approach involves introducing light-absorbing nanoparticles into sebaceous follicles before destroying the follicles using selective photothermolysis. We aimed to investigate efficient methods for introducing gold and platinum nanoparticles into sebaceous follicles and to identify suitable laser equipment and parameters for the effective destruction of these follicles. METHODS: We used porcine skin as the experimental model. We compared the efficacies of a thulium laser, ultrasound, and manual massage and evaluated the optimal method for delivering nanoparticles in close proximity to sebaceous follicles. Subsequently, a 1064-nm-wavelength neodymium-doped yttrium aluminum garnet (Nd: YAG) laser was employed to induce selective photothermolysis. We compared different parameters to identify the optimal pulse duration and fluence of the Nd: YAG laser. The extent of penetration and destruction of sebaceous follicles was assessed using hematoxylin and eosin (H&E) staining, and a numerical evaluation was conducted. RESULTS: H&E staining showed that irradiation with a long-pulsed Nd: YAG laser following a combination of thulium laser and sonophoresis effectively destroyed sebaceous follicles, with destruction rates exceeding 50%. These results were valid with a long pulse duration and a high fluence of the Nd: YAG laser. CONCLUSION: This study demonstrated that sebaceous follicles can be effectively destroyed through a mixture of gold and platinum nanoparticle delivery by a combination of microchanneling and sonophoresis, followed by selective thermal damage induced by a 1064-nm long-pulsed high-fluence Nd: YAG laser.

1726 nm Lasers for the Treatment of Acne Vulgaris.

The treatment of acne vulgaris traditionally consists of a combination of topical and oral medications. The use of lasers to treat this condition has been an area of increasing research, and several types have previously been used in the treatment of acne. New 1726 nm lasers specifically target the sebaceous gland, which is known to be pivotal in acne pathophysiology. This laser wavelength demonstrates substantial potential as a safe and effective therapeutic option for moderate to severe acne without the risks of systemic therapy. This paper reviews the 1726 nm lasers for acne vulgaris.

Understanding Type 3 Innate Lymphoid Cells and Crosstalk with the Microbiota: A Skin Connection.

Innate lymphoid cells (ILCs) are a diverse population of lymphocytes classified into natural killer (NK) cells, ILC1s, ILC2s, ILC3s, and ILCregs, broadly following the cytokine secretion and transcription factor profiles of classical T cell subsets. Nonetheless, the ILC lineage does not have rearranged antigen-specific receptors and possesses distinct characteristics. ILCs are found in barrier tissues such as the skin, lungs, and intestines, where they play a role between acquired immune cells and myeloid cells. Within the skin, ILCs are activated by the microbiota and, in turn, may influence the microbiome composition and modulate immune function through cytokine secretion or direct cellular interactions. In particular, ILC3s provide epithelial protection against extracellular bacteria. However, the mechanism by which these cells modulate skin health and homeostasis in response to microbiome changes is unclear. To better understand how ILC3s function against microbiota perturbations in the skin, we propose a role for these cells in response to Cutibacterium acnes, a predominant commensal bacterium linked to the inflammatory skin condition, acne vulgaris. In this article, we review current evidence describing the role of ILC3s in the skin and suggest functional roles by drawing parallels with ILC3s from other organs. We emphasize the limited understanding and knowledge gaps of ILC3s in the skin and discuss the potential impact of ILC3-microbiota crosstalk in select skin diseases. Exploring the dialogue between the microbiota and ILC3s may lead to novel strategies to ameliorate skin immunity.

Efficacy of Glycyrrhetinic Acid in the Treatment of Acne Vulgaris Based on Network Pharmacology and Experimental Validation.

Glycyrrhetinic acid (GA) is a saponin compound, isolated from licorice (Glycyrrhiza glabra), which has been wildly explored for its intriguing pharmacological and medicinal effects. GA is a triterpenoid glycoside displaying an array of pharmacological and biological activities, including anti-inflammatory, anti-bacterial, antiviral and antioxidative properties. In this study, we investigated the underlying mechanisms of GA on acne vulgaris through network pharmacology and proteomics. After the intersection of the 154 drug targets and 581 disease targets, 37 therapeutic targets for GA against acne were obtained. A protein-protein interaction (PPI) network analysis highlighted TNF, IL1B, IL6, ESR1, PPARG, NFKB1, STAT3 and TLR4 as key targets of GA against acne, which is further verified by molecular docking. The experimental results showed that GA inhibited lipid synthesis in vitro and in vivo, improved the histopathological damage of skin, prevented mast cell infiltration and decreased the level of pro-inflammatory cytokines, including TNF-α, IL-1ß and IL-6. This study indicates that GA may regulate multiple pathways to improve acne symptoms, and the beneficial effects of GA against acne vulgaris might be through the regulation of sebogenesis and inflammatory responses.

Bioactive Compounds from Medicinal Plants as Potential Adjuvants in the Treatment of Mild Acne Vulgaris.

In recent years, there has been a growing interest in the use of medicinal plants and phytochemicals as potential treatments for acne vulgaris. This condition, characterized by chronic inflammation, predominantly affects adolescents and young adults. Conventional treatment typically targets the key factors contributing to its development: the proliferation of Cutibacterium acnes and the associated inflammation. However, these treatments often involve the use of potent drugs. As a result, the exploration of herbal medicine as a complementary approach has emerged as a promising strategy. By harnessing the therapeutic properties of medicinal plants and phytochemicals, it may be possible to address acne vulgaris while minimizing the reliance on strong drugs. This approach not only offers potential benefits for individuals seeking alternative treatments but also underscores the importance of natural remedies of plant origin in dermatological care. The primary aim of this study was to assess the antimicrobial, antioxidant, and anti-inflammatory properties of plants and their phytochemical constituents in the management of mild acne vulgaris. A comprehensive search of scientific databases was conducted from 2018 to September 2023. The findings of this review suggest that medicinal plants and their phytochemical components hold promise as treatments for mild acne vulgaris. However, it is crucial to note that further research employing high-quality evidence and standardized methodologies is essential to substantiate their efficacy and safety profiles.

Effect of isotretinoin treatment on inflammatory and hematological parameters in patients with acne vulgaris.

PURPOSE: Although the inflammatory and anti-inflammatory effects of isotretinoin (ISO) treatment in patients with acne vulgaris have been discussed in the literature in recent years, no sensitive and specific marker has been found in studies so far. Neutrophil/HDL (high-density lipoprotein) (NHR), lymphocyte/HD L(LHR), platelet/HDL (PHR), and lymphocyte/monocyte (LMR) are new biomarkers related to inflammation. Triglyceride/HDL (TG/HDL), LDL/HDL, and total cholesterol/HDL have been shown to be cardiometabolic risk factors predicting both cardiovascular disease risk and metabolic risk, rather than just a simple dyslipidemia scale. To our knowledge, the relationship between these parameters and ISO treatment has never been studied before. We aimed to evaluate the immuno-inflammatory response of ISO treatment in patients with acne vulgaris with NHR, LHR, PHR, LMR, TG/HDL, LDL/HDL, and total cholesterol/HDL parameters. MATERIALS AND METHODS: In this study, 153 patients who received oral ISO treatment for at least 3 months with a diagnosis of moderate-severe acne vulgaris were evaluated retrospectively. Patients were given oral isotretinoin at a dose of 0.5-1 mg/kg. Pre and post-treatment leukocyte (WBC), neutrophil (NE), lymphocyte (LY), platelet (PLT), red cell distribution width (RDW), plateletcrit (PCT), neutrophil/lymphocyte (NLR), platelet/lymphocyte (PLR), mean platelet volume (MPV), monocyte/lymphocyte (MLR), LMR, total cholesterol, LDL cholesterol, HDL cholesterol, triglyceride, MHR, NHR, LHR, PHR, TG/HDL, total cholesterol/HDL, LDL/HDL parameters were evaluated. RESULTS: It was found that post-treatment WBC and MPV values increased statistically significantly; NLR, neutrophil, and PCT values, on the other hand, decreased significantly (p < 0.05). No statistically significant change was detected in PLR, MLR, LMR, MHR, NHR, LHR, PHR, lymphocyte, monocyte, platelet, and RDW parameters (p > 0.05). It was determined that post-treatment total cholesterol, triglyceride, VLDL, and LDL levels increased statistically significantly; however, the HDL level decreased significantly (p < 0.05). Levels of total cholesterol/HDL, TG/HDL, and LDL/HDL were also found to increase statistically significantly (p < 0.05). CONCLUSION: Our study suggests that the MPV and NLR ratio as biomarkers can be used as indicators of atherosclerosis-related inflammation due to ISO treatment, but the MHR, NHR, LHR, PHR, MLR, LMR ratios cannot be used. Moreover, we believe that the ratios of TG/HDL, LDL/HDL, and total cholesterol/HDL offer a new contribution as indicators of cardiovascular risk and systemic inflammation related to ISO treatment.

Evaluation of isotretinoin effects on depression, sleep apnea and sleep quality.

BACKGROUND: Isotretinoin is used to treat severe acne, treatment-resistant moderate acne, and acne that leads to scarring or psychological distress. It has many side effects and is also associated with depression, sleep apnea, and sleep disturbances. OBJECTIVES: In this study, we aimed to evaluate the effects of isotretinoin on depression, sleep apnea, and sleep quality. METHODS: A total of 42 patients diagnosed with acne and started isotretinoin treatment were included in the study. In order to compare the effects of isotretinoin, patients were asked to fill out a questionnaire containing the Beck Depression Inventory (BDI), the Berlin Questionnaire (BQ), and the Pittsburg Sleep Quality Index (PSQI) at baseline and third months of treatment. RESULTS: There was no statistically significant difference in BDI, BQ, and PSQI scores between the 1st and 3rd months of treatment (p = .53, p = .5, p = .35). CONCLUSION: This study showed that isotretinoin had no significant effects on depression and sleep quality.
