Shi Y, Lain E, Frasson N, Ortiz-Brugués A, Stennevin A. The Real-World Effectiveness and Tolerability of a Soothing Cream Containing the Postbiotic Aquaphilus dolomiae Extract-G2 for Skin Healing. Dermatol Ther (Heidelb) 2024; 14:697-712. [PMID: 38451421 PMCID: PMC10965845 DOI: 10.1007/s13555-024-01119-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Accepted: 02/13/2024] [Indexed: 03/08/2024] Open
Abstract
INTRODUCTION In vitro and pre-marketing clinical data have shown the healing properties of a postbiotic extract from Aquaphilus dolomiae (ADE-G2). The effectiveness and tolerability of an ADE-G2-based cream were therefore evaluated for the management of minor skin impairment and wound healing in a large population of subjects in routine clinical practice. METHODS A real-world, international, pre-post comparative study was conducted in infants, children, and adults with various types of superficial skin impairment who used the study product daily for around 3 weeks according to their dermatologist's advice. Immediate and follow-up changes in dermatologic signs and symptoms were assessed through clinical scoring. User satisfaction, overall product effectiveness, and tolerability were also evaluated. Analyses were performed in the whole study population and in subject subgroups according to skin impairment type and age. RESULTS Overall, 1317 subjects (83.1% adults, 72.0% female) were included. Dermatologists reported effectiveness and "good" or "very good" tolerability of the cream in 93.8% (1221/1302) and 98.5% (1278/1297) of subjects, respectively. Immediate symptom relief after the first application was reported by 88.3% (849/962) of subjects. After several weeks of regular use (16.7 ± 11.6 days), dermatologic signs and symptoms significantly improved in the whole study population and in the subgroups, with mean decreases in severity scores ranging from -34.5% to -92.5% (p < 0.0001). The smallest improvements were found in subjects with oncologic treatment-related skin impairment. At study end, most users (> 95%) were "very satisfied" or "satisfied" with the cream and found that skin healing was rapid and of good quality. CONCLUSION The ADE-G2-based cream proved to be effective and well tolerated in real-life conditions for the management of minor skin impairment in a large and varied cohort of subjects. This product, used as a standalone or adjunctive regimen, can help accelerate the healing of various types of superficial skin impairment.

Abstract
The interplay between the skin microbiome and its host is a complex facet of dermatological health and has become a critical focus in the development of microbiome cosmetics. The skin microbiome, comprising various microorganisms, is essential from birth, develops over the lifespan, and performs vital roles in protecting our body against pathogens, training the immune system, and facilitating the breakdown of organic matter. Dysbiosis, an imbalance of these microorganisms, has been implicated in a number of skin conditions such as acne, atopic dermatitis, and skin cancer. Recent scientific findings have spurred cosmetic companies to develop products that preserve and enhance the skin's microbial diversity balance. These products may incorporate elements like prebiotics, probiotics, and postbiotics, which are beneficial for the skin microbiome. Beyond topical products, there's increasing interest in ingestible beauty supplements (i.e. oral probiotics), highlighting the connection between the gut and skin. This review examines the influence of the microbiome on skin health and the emerging trends of microbiome skincare products.

Should Emollients Be Recommended for the Prevention of Atopic Dermatitis?-New Evidence and Current State of Knowledge. J Clin Med 2024; 13:863. [PMID: 38337555 PMCID: PMC10856443 DOI: 10.3390/jcm13030863] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Revised: 01/17/2024] [Accepted: 01/30/2024] [Indexed: 02/12/2024] Open
Abstract
INTRODUCTION Atopic dermatitis (AD) is a chronic, pruritic skin disease with complex pathogenesis, which affects about 43 million children aged 1-4 years. One of the most known methods of alleviating symptoms of AD is emollient treatment, which varies depending on formulation and additional active ingredients. There is some evidence that emollients could be used in AD prevention in high-risk children. MATERIALS AND METHODS A search of the literature from Cochrane Library, PubMed and Medline was conducted between August and September 2023 with the following keywords: "atopic dermatitis", "emollients", and "prevention". Only randomised clinical trials published in the last 5 years were included into the meta-analysis. RESULTS Considering the inclusion criteria only 11 randomized clinical trials were taken into account, and six of them proved lack of effect of emollients in the prevention of atopic dermatitis among neonates from AD risk groups. CONCLUSIONS Emollient treatment has a good safety profile and most of the ingredients used in formulations are nonirritant for sensitive newborn and infant skin. There is some evidence of the positive effects of emollient treatment in prevention of AD in predisposed populations. The relatively high cost of emollient treatment (vs regular infant skin-care routine) would support the necessity for further evaluation of their effectiveness in nonpredisposed populations.

Abstract
Emollients are the mainstay maintenance treatment for atopic dermatitis (AD). A novel generation of emollients, 'emollients plus', containing active, non-medicated substances, has softened the distinction between emollients and topical drugs. A literature search for selected key words was performed using PubMed. Additional papers were identified based on author expertise. Whilst the inclusion of five components of an ideal emollient has been proposed, no such consensus exists for emollients plus and they can vary markedly in their composition and modes of action for AD treatment. This could have a profound effect on their clinical efficacy. The efficacy of emollients plus in restoring and maintaining skin barrier function has been demonstrated on multiple levels, with evidence reported for their effects on the physical and biochemical, microbial, immunological, and neurosensory barriers. When selecting an appropriate AD treatment approach, the safety profiles of the available topical therapies must be carefully considered. There are several proposed treatment approaches for AD, including preventive, proactive, intermittent, and synergistic approaches. Emollients plus may be effective not only as maintenance therapy for AD, but also when used synergistically with anti-inflammatory pharmacological therapies.

Abstract
The evidence- and consensus-based guideline on atopic eczema was developed in accordance with the EuroGuiDerm Guideline and Consensus Statement Development Manual. Four consensus conferences were held between December 2020 and July 2021. Twenty-nine experts (including clinicians and patient representatives) from 12 European countries participated. This second part of the guideline includes recommendations and detailed information on basic therapy with emollients and moisturizers, topical anti-inflammatory treatment, antimicrobial and antipruritic treatment and UV phototherapy. Furthermore, this part of the guideline covers techniques for avoiding provocation factors, as well as dietary interventions, immunotherapy, complementary medicine and educational interventions for patients with atopic eczema and deals with occupational and psychodermatological aspects of the disease. It also contains guidance on treatment for paediatric and adolescent patients and pregnant or breastfeeding women, as well as considerations for patients who want to have a child. A chapter on the patient perspective is also provided. The first part of the guideline, published separately, contains recommendations and guidance on systemic treatment with conventional immunosuppressive drugs, biologics and janus kinase (JAK) inhibitors, as well as information on the scope and purpose of the guideline, and a section on guideline methodology.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory dermatosis with periods of exacerbation and remissions. AD is characterized by intense, persistent pruritus and heterogeneity in clinical symptomatology and severity. Therapeutic goals include the amelioration of cutaneous eruptions, diminishing relapses and eventually the disease burden. To date, topical corticosteroids (TCS) and calcineurin inhibitors (TCI) have yet been deemed the mainstay of topical treatments in AD management. Nevertheless, despite their indisputable efficiency, TCS and TCI are not indicated for continuous long-term use given their safety profile. While research in AD has concentrated predominantly on systemic therapies, more than 30 novel topical compounds are under development. The existing data appear encouraging, with some regimens that are already FDA-approved (ruxolitinib was the most recent in September 2021) and several pharmaceutical pipeline products for mild-to-moderate AD that are in an advanced stage of development, such as tapinarof, difamilast and roflumilast. Larger, long-term studies are still required to evaluate the efficacy and safety of these novel compounds in the long run and weigh their advantages over present treatments. In this review, we aim to provide an overview of the latest knowledge about AD topical treatments, echoing upcoming research trends.

Abstract
Currently, there are a few detailed guidelines on the overall management of children and adolescents with moderate-severe atopic dermatitis. AD is a complex disease presenting with different clinical phenotypes, which require an individualized and multidisciplinary approach. Therefore, appropriate interaction between primary care pediatricians, pediatric allergists, and pediatric dermatologists is crucial to finding the best management strategy. In this manuscript, members of the Italian Society of Pediatric Allergology and Immunology (SIAIP), the Italian Society of Pediatric Dermatology (SIDerP), and the Italian Society of Pediatrics (SIP) with expertise in the management of moderate-severe atopic dermatitis have reviewed the latest scientific evidence in the field. This narrative review aims to define a pathway to appropriately managing children and adolescents with moderate-severe atopic dermatitis.

Abstract
INTRODUCTION Xerosis is a common skin side effect of current anticancer therapies, including chemotherapy, targeted therapy, radiotherapy, and hormonotherapy. We evaluated the effectiveness of an emollient PLUS containing an Aquaphilus dolomiae extract (ADE-G1) for the management of xerosis in adult patients treated for cancer. METHODS This real-world, prospective, observational, multicenter study involved 319 xerotic cancer patients, who were prescribed the study product according to the usual practice of their physician. The practitioner assessed xerosis severity and objective clinical signs, and the patients assessed subjective clinical signs and the impact of their skin condition on their quality of life, at inclusion and after around 4 weeks of use. Overall effectiveness and tolerance were assessed at the end of the study. Clinical success was defined by the combination of several of these effectiveness outcomes. RESULTS Daily application of the emollient PLUS reduced xerosis severity in 62.7% of patients (p < 0.0001). The mean total severity scores for objective and subjective clinical signs were reduced by 67.7% and 57.4% (p < 0.0001), respectively, compared with baseline. The mean Dermatology Life Quality Index (DLQI) score also significantly improved at the end of follow-up (-56.6%, p < 0.0001). The product was rated as "effective" or "very effective" by the physician for over 80% of patients, regardless of the initial severity grade of xerosis. Overall clinical success was achieved in 73.7% of patients. A trend toward higher effectiveness and clinical success was observed in patients under hormonotherapy. The study product was well tolerated, regardless of the anticancer therapy being received. CONCLUSION This study shows that the emollient PLUS containing ADE-G1 is an effective treatment for xerosis in cancer patients, regardless of the initial grade of xerosis and the anticancer treatment received.

Abstract
Many pregnant women experience skin symptoms caused by immunological, metabolic or other changes that occur in their body during pregnancy. One of the most common complaints of pregnant women is itchy skin. In about 20% of cases, itching in pregnant women is associated with atopic skin lesions. Histologically, these lesions are indistinguishable from atopic dermatitis, which also tends to worsen during pregnancy. It is believed that these lesions are due to increased production of Th2 cytokines (interleukin-4 and -10) in the body of a pregnant woman. Topical glucocorticosteroids and skin care products are best treatments for atopic skin lesions of pregnant women and exacerbation of atopic dermatitis. In cases of limited rashes or mild dermatitis, only care products with a strong moisturizing effect can be used. Using moisturizers can help minimize itching and skin discomfort. One of these agents that we use in practice is XeraCalm A.D Lipid-Replenishing cream, the unique formula of which not only has a regenerating and antipruritic effect, but also enhances the natural immunity of the skin.

Abstract
Frequently described as 'the worst itch' one can ever experience scabies itch is the hallmark of Sarcoptes scabiei mite infestation. Notably, the itchiness often persists for weeks despite scabicides therapy. The mechanism of scabies itch is not yet fully understood, and effective treatment modalities are still missing which can severely affect the quality of life. The aim of this review is to provide an overview of the scope of itch in scabies and highlight candidate mechanisms underlying this itch. We herein discuss scabies itch, with a focus on the nature, candidate underlying mechanisms and treatment options. We also synthesize this information with current understanding of the mechanisms contributing to non-histaminergic itch in other conditions. Itch is a major problem in scabies and can lead to grave consequences. We provide the latest insights on host-mite interaction, secondary microbial infection and neural sensitization with special emphasis on keratinocytes and mast cells to better understand the mechanism of itch in scabies. Also, the most relevant current modalities remaining under investigation that possess promising perspectives for scabies itch (i.e. protease-activated receptor-2 (PAR-2) inhibitor, Mas-related G protein-coupled receptor X2 (MRGPRX2) antagonist) are discussed. Greater understanding of these diverse mechanisms may provide a rational basis for the development of improved and targeted approaches to control itch in individuals with scabies.

Characteristics associated with clinical response to Comano thermal spring water balneotherapy in pediatric patients with atopic dermatitis. Ital J Pediatr 2021; 47:91. [PMID: 33863356 PMCID: PMC8052702 DOI: 10.1186/s13052-021-00971-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2020] [Accepted: 01/21/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Several studies have investigated the efficacy of balneotherapy in atopic dermatitis (AD), including a pediatric open randomized clinical trial conducted at the Comano thermal spring water center, which showed a significant reduction in AD severity and an improvement of the quality of life. However, so far many studies on balneotherapy in pediatric AD have included relatively small populations without identifying patients' characteristics associated with their response. The aim of the present study was to identify any features associated with the clinical response to the Comano thermal spring water balneotherapy in a large cohort of pediatric AD patients. METHODS An observational study was conducted on 867 children aged ≤16 years (females 50.5%, mean patient's age 5.9 years, standard deviation ±3.6 years) with mild to severe AD who underwent balneotherapy at the Comano thermal spring water center (Comano, Trentino, Italy) from April to October 2014. Patients were stratified according to their disease severity, which was evaluated using five SCORing Atopic Dermatitis (SCORAD) categories before and immediately after a thermal spring water balneotherapy course. Potential characteristics associated with the patients' clinical response to Comano thermal spring water balneotherapy were investigated. RESULTS A statistically significant improvement in AD severity was observed after Comano thermal spring water balneotherapy (p < 0.0001). A significantly higher percentage of patients achieving improvement in AD severity was reported among children ≤4 years old (p < 0.0001) with early-onset AD (p < 0.0001), severe AD (p < 0.0001) or coexistent reported food allergies (p < 0.01). The therapy was well tolerated, and no relevant adverse effects were reported during the treatment course. CONCLUSIONS Comano thermal spring water balneotherapy is a safe complementary treatment for pediatric patients with AD, as it was able to reduce the disease severity, especially in children ≤4 years old, with early onset AD, severe AD or concomitant food allergies.

Abstract
The anti-inflammatory effects of a 50% aqueous extract of Rosa roxburghii fruit (RRFE) and two ellagitannins (strictinin and casuarictin) isolated from the RRFE were evaluated in a cell model of skin inflammation induced by self-RNA released from epidermal cells damaged by UV ray (UVR) irradiation. The RRFE inhibited interleukin-8 (IL-8) mRNA expression in normal human epidermal keratinocytes (NHEKs) stimulated with polyinosinic:polycytidylic acid (poly(I:C)), a ligand of toll-like receptor-3 (TLR-3). The plant-derived anti-inflammatory agents, dipotassium glycyrrhizinate (GK2) and allantoin, had no influence on the IL-8 expression. The purified compounds, strictinin and casuarictin, inhibited the IL-8 mRNA expression and IL-8 release induced in NHEKs by poly(I:C). These ellagitannins were thus found to be responsible for the biological activity exhibited by the RRFE. This study demonstrates that RRFE and isolated RRFE compounds show promise as ingredients for products formulated to improve skin disorders induced by UVR irradiation.

Abstract
Thermal therapy has gained popularity over the years, and Portugal is one of the richest European countries in mineral therapeutic waters. The interest in the use of these natural mineral waters (NMW) for dermatologic purposes is continuously growing but there is a lack of scientific studies supporting its health benefits. The study aims to investigate the effect of a silica-rich NMW in skin cell homeostasis using two representative cell lines of the epidermis and dermis, keratinocytes and fibroblasts, respectively, in addition to a macrophage cell line. Mouse skin fibroblasts, macrophages and human keratinocytes were exposed to culture medium prepared with NMW. Cell metabolism (MTT or resazurin assays) and cell proliferation (trypan blue exclusion dye assay) were investigated. Migration (scratch-wound assay) and senescence (β-galactosidase activity assay) of fibroblasts were also studied. Exposure to NMW compromised the cell metabolic state of all the cell lines tested. This impairment was more pronounced in skin keratinocytes (60% reduction) relatively to skin fibroblasts (45% reduction) or macrophages (25% reduction). Proliferation of macrophages was reduced threefold upon exposure to thermal water, compared to controls. No differences were observed in migration between fibroblasts exposed to NMW and controls, while a potentiation of senescence of these cells was observed. Our results shed light in the bioactive effects of a silica-rich NMW supporting its therapeutic use. A reduction in both cell metabolism and proliferation of keratinocytes and macrophages supports the empirical clinical benefits of this NMW in hyperkeratotic conditions, such as psoriasis and atopic dermatitis.

Abstract
INTRODUCTION Xerosis and pruritus are common manifestations of numerous dermatologic and systemic diseases. We evaluated the effectiveness of an emollient containing an Aquaphilus dolomiae extract (ADE-G1) for the management of pruritus and xerosis in patients of all age with a range of dermatologic and systemic diseases. METHODS This open-label, real-world study involved 5910 patients from 33 European, South American, Asian, and North and South African countries, who applied the product for 7 days twice daily to the face and body after the skin had been cleansed and dried. The physician assessed xerosis severity and patients assessed pruritus severity, the duration of itch, sleep quality, and the impact of their skin disease on their quality of life, using scales derived from the SCORing Atopic Dermatitis (SCORAD) index and questionnaires, at inclusion and after 7 days of use. RESULTS The 7-day care regimen resulted in 56% and 60% reductions in xerosis and pruritus severity, respectively, regardless of the underlying pathology (p < 0.0001), with the largest decreases observed for patients with ichthyosis for xerosis and for patients post scabies treatment for pruritus. The mean sleep disturbance and mean total Dermatology Life Quality Index (DLQI) scores were also reduced by 58% and 60% (p < 0.0001), respectively. The emollient was effective whether the product was used alone or in combination with topical or systemic treatments and was well tolerated. CONCLUSION Our study shows that the 7-day regimen with the emollient was a universally effective treatment for pruritus and xerosis, regardless of the underlying pathology.

Abstract
Aquaphilus dolomiae (AD) is a unique isolate from Avène Thermal Spring Water. I-Modulia, the first biotech extract from culture of AD, was used as immune modulator in Th2 inflammatory models. In this short publication, firstly we describe generation of two AD de novo extracts specifically designed for repairing and for neuroinflammation modulation activities which will be described, respectively, in two other articles in this supplement. Finally, for I-modulia, we describe new data on inhibition of human mast cell degranulation in vitro and its effect on substance P-induced neurogenic inflammation on ex vivo human skin explants.

Abstract
BACKGROUND A biological concentrate was produced from cultures of an Avène aquatic microflora isolate, namely Aquaphilus dolomiae. Some of the beneficial effects on diseased and damaged skin are thought to be due to the presence of this microorganism. AIMS An extract of A. dolomiae (A. dolomiae extract-G2, ADE-G2) was evaluated for its wound-healing effects using in vitro and ex vivo models of injured skin. METHODS The effect of ADE-G2 on the proliferation of fibroblasts, migration of keratinocytes and re-epithelialization of ex vivo wounded skin explants was measured. Antimicrobial protection by ADE-G2 was measured by analysing the gene expression of a panel of antimicrobial proteins (AMPs) in keratinocytes (RNASE7, S100A7, DEFB4A/B and DEFb103B), as well as the protein encoded by DEFB4A-B (hBD2) in the medium. RESULTS ADE-G2 increased fibroblast proliferation and keratinocyte migration, as well as re-epithelialization of wounded ex vivo skin. ADE-G2 induced the expression of all AMP genes analysed in keratinocytes, as well as stimulated the release in to the medium of hBD2 peptide, encoded by DEFB4A/B. CONCLUSIONS We have shown the broad spectrum of the repairing properties of the A. dolomiae extract, ADE-G2. These results support the use of ADE-G2 as a promising component for use in formulations aimed at repairing skin, limiting wound superinfection and preventing complicated wounds.

Abstract
BACKGROUND Atopic dermatitis (AD) is a common skin disease characterized by recurrent pruritic inflammatory skin lesions and defects of the skin barrier. Bacterial infection with Staphylococcus aureus contributes to increased severity of AD by compromising the barrier further. A microorganism component of Avène Thermal Spring Water, Aquaphilus dolomiae, is thought to contribute to some of its beneficial effects to skin, eg AD alleviation. AIMS Here, we have investigated the effects of an extract of A. dolomiae, A. dolomiae extract-G1 (ADE-G1), on the structural barrier function of keratinocytes, tight junction (TJ) protein expression and the expression of several genes altered in AD patients. METHODS An epidermal cell culture model mimicking the AD environment and phenotype was used, in which S. aureus-infected cell cultures of normal human epidermal keratinocytes were exposed to a proinflammatory environment. Endpoints measured included the transepithelial electrical resistance (TER) and immunohistological staining of the epidermal TJ proteins, claudin and occludin. Additional analysis was made of several genes known to be differentially regulated in skin from AD patients (C-C motif chemokine ligand 20 (CCL20), interleukin-8 (IL-8), S100 calcium binding protein A7 (S100A7), defensin beta 4 (DEFB4) and filaggrin). RESULTS Aquaphilus dolomiae extract-G1 strongly increased TER in non-infected cells and provided protection against infection by overcoming the decrease in TER induced by the infection with S. aureus. In infected cells exposed to a pro-inflammatory environment - depicting AD-like conditions - TER protection by ADE-G1 was still observed. Gene expression analysis of infected and pro-inflammatory stimulated cells indicated that ADE-G1 modulated the inflammatory response (induced IL-8 and attenuated CCL20 expression), increased antimicrobial activities (induced DEFB4 and A100A7) and strengthened barrier function (restored filaggrin expression). CONCLUSIONS ADE-G1 reinforces barrier function and strongly protects TJ barrier disruption induced by bacterial infection and inflammation.

Abstract
BACKGROUND Inflammatory skin disorders, including atopic dermatitis (AD), associated pruritus and sensitive skin, have a complex multifactorial pathogenesis including neurogenic inflammation involving the release in blood and skin of neurotransmitters such as substance P (SP). AIMS AND METHODS In vitro models evaluated the effect of the original biological extract of Aquaphilus dolomiae extract-G3 (ADE-G3) on cutaneous neurogenic inflammation. RESULTS ADE-G3 significantly inhibited SP-stimulated release of IL-1β and TNF-α from normal human epidermal keratinocytes; significantly and dose-dependently inhibited SP-stimulated activation of human mast cells; significantly inhibited veratridine-stimulated release of SP from human sensory neurons; modulated expression of genes involved in lipid synthesis, innate immunity, corneocyte scaffolding and epidermal differentiation in a histamine-sensitized reconstructed human epidermis model; and, when applied topically to ex vivo human explants, inhibited IL-8 and histamine release. CONCLUSIONS Topically applied ADE-G3, once formulated, may improve neuro-inflammation in patients with inflammatory skin disorders.

Abstract
Psoriasis is a common non-contagious chronic inflammatory skin lesion, with frequent recurrence. It mainly occurs due to aberrant regulation of the immune system leading to abnormal proliferation of skin cells. However, the pathogenic mechanisms of psoriasis are not fully understood. Although most of the current therapies are mostly efficient, the side effects can result in therapy stop, which makes the effectiveness of treatment strategies limited. Therefore, it is urgent and necessary to develop novel therapeutics. Here, we investigated the efficacy of chrysin, a plant flavonoid, which we previously reported to possess strong antioxidant and anti-inflammatory effects, against psoriasis-like inflammation. Our results revealed that chrysin significantly attenuated imiquimod-induced psoriasis-like skin lesions in mice, and improved imiquimod-induced disruption of skin barrier. Moreover, the TNF-α, IL-17A, and IL-22-induced phosphorylation of MAPK and JAK-STAT pathways, and activation of the NF-κB pathway were also attenuated by chrysin pretreatment of epidermal keratinocytes. Most importantly, chrysin reduced TNF-α-, IL-17A-, and IL-22-induced CCL20 and antimicrobial peptide release from epidermal keratinocytes. Thus, our findings indicate that chrysin may have therapeutic potential against inflammatory skin diseases. Our study provides a basis for further investigating chrysin as a novel pharmacologic agent and contributes to the academic advancement in the field of Chinese herbal medicine.

Abstract
Atopic dermatitis is a chronic and recurrent inflammatory dermatosis with concomitant intensive pruritus, and is diagnosed both in children and adults. Atopic dermatitis-patients are predisposed to have bacterial, viral and fungal skin infections; they also suffer from an increased risk of developing food allergies (especially, at an infantile age), allergic rhinitis, or bronchial asthma (a so-called atopic march). Currently, an increasing atopic dermatitis incidence constitutes a serious medical problem that regards not only dermatology and allergology, but also paediatrics, and family medicine. The basis for atopic dermatitis treatment and prophylaxis is restoration of epidermal barrier functions by means of tailored emollients. Atopic dermatitis therapies should effectively eliminate clinical symptoms of the disease, prevent exacerbations as well as complications, and improve patients' quality of life.

Abstract
Background Hydrotherapy appears as a valuable therapeutic tool in the management of patients suffering from chronic skin inflammatory diseases. Nevertheless, the underlying immune mechanisms of these beneficial effects remain poorly understood. To better understand the biological effects of thermal spring water on the immune system, we investigated the effects of Avène thermal spring water (ASW) on dendritic cells as key cells participating in the control of the immune response. Methods Dendritic cells (DCs) were generated from human monocytes and matured with LPS in ASW-based culture medium or in dexamethasone supplemented culture medium as an anti-inflammatory treatment. The phenotypes and abilities of these DCs to produce cytokines and induce allogeneic T cell response was next assessed. Results We showed that ASW modulated the differentiation of monocytes into DCs and impacted the DC maturation upon LPS priming. We observed a reduction of the CD83, CD86, CD1a and HLA-DR molecule expression and a decrease of IL-12 and IL-23 production whereas IL-10 production was increased. LPS-primed DCs generated in presence of ASW exhibited a reduced capacity to induce naive CD4+ T cell proliferation and IFN-γ and IL-17 production. Conclusion Our study showed that ASW is endowed with an immunomodulatory potential. ASW limits the DC stimulatory capacity of Th1 and Th17 cell responses by impairing their maturation, IL-12 and IL-23 production and accessory cell function.

Abstract
Human hosts a large number of microorganisms that constitute its microbiome and the vast majority of them are very useful and even essentials. The human microbiome is a complex ecosystem where live populations of transient or resident microorganisms. The process of co-development or co-adaptation played a major role in the establishment of indigenous communities and help explain the dominance of positive interactions (commensal, symbiotic or mutualistic) in the human-microorganism relationship. The assimilation of nutrients, production of anti-inflammatory compounds, defense against pathogens, vitamin production or stimulating the immune system are some of the key benefits of the indigenous microorganisms. Understanding the skin microbiome opens new exploratory fields and represents a real challenge for both the academic knowledge and the development of new therapeutic approaches.

Abstract
INTRODUCTION AND OBJECTIVES Atopic dermatitis (AD) is the most common cutaneous inflammatory disease in both adults and children. Although emerging therapeutic approaches are being investigated for the management of pediatric AD, it still needs to be managed with conventional treatments. This consensus document is aimed at providing an update on general management and therapies of pediatric AD, defining practical recommendations for using both topical and systemic agents. MATERIAL AND METHODS A panel of experts consisting of dermatologists and pediatricians were convened in order to define statements, through a Delphi process, standardizing the management of AD in pediatric subjects in a real-world setting. RESULTS A set of practical recommendations obtaining an at least 75% agreement was presented. CONCLUSIONS This set of practical recommendations represents a simple and fast snapshot on the pediatric use of common anti-AD therapeutics.

Abstract
Recent findings highlight the role of skin microbiome in modulating immune function and inflammatory response. This systematic review aims to investigate the effects of muds, already used for the treatment of several rheumatic and dermatologic conditions, on skin microbiome. Medline via PubMed, Embase, Cochrane Library, and Google Scholar were searched for articles about the effects of therapeutic muds on microorganisms of skin microbiome. Five studies were included in the review and critically appraised. Limited data suggest that muds have various properties that may explain their action on skin microbiome, with different effects on commensal and pathogenic microorganisms. Further investigation on this topic is needed to better characterize the effects of different muds on skin microbiome, thus possibly extending their indications.

Abstract
This guideline was developed as a joint interdisciplinary European project, including physicians from all relevant disciplines as well as patients. It is a consensus-based guideline, taking available evidence from other guidelines, systematic reviews and published studies into account. This first part of the guideline covers methods, patient perspective, general measures and avoidance strategies, basic emollient treatment and bathing, dietary intervention, topical anti-inflammatory therapy, phototherapy and antipruritic therapy, whereas the second part covers antimicrobial therapy, systemic treatment, allergen-specific immunotherapy, complementary medicine, psychosomatic counselling and educational interventions. Management of AE must consider the individual clinical variability of the disease; highly standardized treatment rules are not recommended. Basic therapy is focused on treatment of disturbed barrier function by hydrating and lubricating topical treatment, besides further avoidance of specific and unspecific provocation factors. Topical anti-inflammatory treatment based on glucocorticosteroids and calcineurin inhibitors is used for flare management and for proactive therapy for long-term control. Topical corticosteroids remain the mainstay of therapy, whereas tacrolimus and pimecrolimus are preferred in sensitive skin areas and for long-term use. Topical phosphodiesterase inhibitors may be a treatment alternative when available. Adjuvant therapy includes UV irradiation, preferably with UVB 311 nm or UVA1. Pruritus is targeted with the majority of the recommended therapies, but some patients may need additional antipruritic therapy. Antimicrobial therapy, systemic anti-inflammatory treatment, immunotherapy, complementary medicine and educational intervention will be addressed in part II of the guideline.

Abstract
Psoriasis is a common inflammatory disease. It affects 1-3% of the population worldwide and is associated with increasing medical costs every year. Typical psoriatic skin lesions are reddish, thick, scaly plaques that can occur on multiple skin sites all over the body. Topical application of imiquimod (IMQ), a toll-like receptor (TLR)7 agonist and potent immune system activator, can induce and exacerbate psoriasis. Previous studies have demonstrated that isoflavone extract has an antioxidant effect which may help decrease inflammation and inflammatory pain. Through in vivo studies in mice, we found that the topical application to the shaved back and right ear of mice of isoflavone extract prior to IMQ treatment significantly decreased trans-epidermal water loss (TEWL), erythema, blood flow speed, and ear thickness, while it increased surface skin hydration, and attenuated epidermal hyperplasia and inflammatory cell infiltration. Through in vitro experiments, we found that isoflavone extract can reduce IL-22, IL-17A, and TNF-α-induced MAPK, NF-κB, and JAK-STAT activation in normal human epidermal keratinocytes. At the mRNA level, we determined that isoflavone extract attenuated the increased response of the TNF-α-, IL-17A-, and IL-22- related pathways. These results indicate that isoflavone extract has great potential as an anti-psoriatic agent and in the treatment of other inflammatory skin diseases.

Abstract
Carnosol is a phenolic antioxidant present in rosemary (Rosmarinus officinalis). It is known for anti-inflammatory effects, analgesic activity and anti-cancer effects. However, no study has been dedicated yet to its effect on atopic dermatitis (AD). Here, we show that carnosol effectively inhibited LPS-induced nitric oxide (NO) generation and expression of inflammatory marker proteins (iNOS and COX-2) in RAW 264.7 cells. In addition, carnosol effectively inhibits the phosphorylation of STAT3 and DNA binding activity in RAW 264.7 cells. Pull down assay and docking model analysis showed that carnosol directly binds to the DNA binding domain (DBD) of STAT3. We next examined the anti-atopic activity of carnosol (0.05 µg/cm2) using 5% Phthalic anhydride (PA)-induced AD model in HR1 mice. Carnosol treatment significantly reduced 5% PA-induced AD like skin inflammation in skin tissues compared with control mice. Moreover, carnosol treatment inhibits the expression of iNOS and COX-2 in skin tissue. In addition, the levels of TNF-α, IL-1β, and Immunoglobulin-E in blood serum was significantly decreased in carnosol treated mice compared with those of 5% PA treated group. Furthermore, the activation of STAT3 in skin tissue was decreased in carnosol treated mice compared with control mice. In conclusion, these findings suggest that carnosol exhibited a potential anti-AD activity by inhibiting pro-inflammatory mediators through suppression of STAT3 activation via direct binding to DBD of STAT3.
