Abstract
INTRODUCTION Atopic dermatitis (AD) is a chronic immuno-inflammatory skin disease. Crisaborole ointment, 2%, is a nonsteroidal phosphodiesterase 4 inhibitor approved for the treatment of mild to moderate AD. This post hoc analysis assesses the efficacy and safety of crisaborole in Chinese patients aged ≥ 2 years with mild to moderate AD. METHODS We evaluated the efficacy and safety of crisaborole in Chinese patients from the vehicle-controlled, phase 3 CrisADe CLEAR study. Patients were randomly assigned 2:1 to receive crisaborole or vehicle twice daily, respectively, for 28 days. The primary endpoint was percent change from baseline in Eczema Area and Severity Index (EASI) total score at day 29. Key secondary endpoints were improvement in Investigator's Static Global Assessment (ISGA), ISGA success, and change from baseline in weekly average Peak Pruritus Numerical Rating Scale (PP-NRS) score. Adverse events were documented. RESULTS Of 391 patients in the overall study, 237 were from China, 157 assigned to crisaborole and 80 assigned to vehicle. A greater reduction in percent change from baseline in EASI total score at day 29 was shown in the crisaborole vs. vehicle group (least squares mean [LSM]: -66.34 [95% (confidence interval) CI -71.55 to -61.12] vs. -50.18 [95% CI -58.02 to -42.34]). Response rates for achievement of ISGA improvement (43.2% [95% CI 35.4-51.1] vs. 33.4% [95% CI 22.5-44.2]) and ISGA success (31.7% [95% CI 24.3-39.0] vs. 21.5% [95% CI 12.1-30.9]) at day 29 were higher in the crisaborole vs. vehicle group. A greater reduction in change from baseline in weekly average PP-NRS score at week 4 was observed in the crisaborole vs. vehicle group (LSM: -1.98 [95% CI -2.34 to -1.62] vs. -1.08 [95% CI -1.63 to -0.53]). No new safety signals were observed. CONCLUSION Crisaborole was effective and well tolerated in Chinese patients aged ≥ 2 years with mild to moderate AD. TRIAL REGISTRATION ClinicalTrials.gov, NCT04360187.

Abstract
Atopic dermatitis (AD) is an abnormal inflammatory response in the skin to food, environmental IgE, or non-IgE allergens. This disease belongs to a group of inflammatory diseases that affect both children and adults. In highly developed countries, AD is diagnosed twice as often in children than in adults, which may possibly be connected to increased urbanization. The immune system's pathomechanisms of AD involve humoral mechanisms with IgE, cellular T lymphocytes, dendritic cells occurring in the dermis, Langerhans cells occurring in the epidermis, and other cells infiltrating the site of inflammation (eosinophils, macrophages, mast cells, neutrophils, and basophils). Cytokines are small proteins that affect the interaction and communication between cells. This review characterizes cytokines and potential aspects of the treatment of atopic dermatitis, as well as new strategies that are currently being developed, including targeting cytokines and their receptors.

Abstract
Atopic dermatitis is one of the most common inflammatory skin diseases among children and adults. Over the last 5 years, the armamentarium for the treatment of this disease, with both topical and systemic drugs, has increased. Treat-to-target is basically the concept where a treatment goal and a time frame for that goal is set at initiation of a new treatment, and if the goals are not achieved in time, treatment will be adjusted. In clinical trials, treatment targets are based on scoring systems for disease severity as recommended by the Harmonizing Outcome Measure for Eczema (HOME) initiative, with the primary endpoint being a reduction of at least 75% of the baseline Eczema Area and Severity Index (EASI) score (EASI-75). The question, however, is if these are useful targets in real-world settings and how this should be implemented in everyday clinical practice. In rheumatology, setting a measurable target and a time frame for an instigated therapy has been shown to lead to more efficient and successful treatment. For atopic dermatitis, the instruments recommended by HOME form the core outcome measures for the treat-to-target frameworks published to date, which are based on expert consensus and Delphi processes. Although atopic dermatitis patients have a high risk of co-morbidities, including physical, psychological and socioeconomic, instruments to measure the severity of co-morbidities have not been included in these existing frameworks. In order to apply a treat-to-target strategy that is meaningful for both the patient and the doctor, validated tools for the measurement of treatment effect on co-morbidities exist and should be included in a shared decision-making process with the individual patient when choosing which targets to aim for and what should be considered treatment success. An obvious limitation for the implementation of a treat-to-target strategy in the clinical setting with atopic dermatitis is that retrieving the data needed is very time consuming. This could to some degree be mitigated by the use of electronic applications in which patients could report their outcomes.

Abstract
Comel-Netherton syndrome, or Netherton syndrome (NS), is a rare chronic genetic skin condition affecting the daily life of patients, which often results in poorly developed social skills and anxiety. Genetic predisposition plays a key role alongside the clinical findings, and clinicians must be aware of it as it can mimic other well-known skin conditions. Diagnosis is challenging both clinically and histologically. Clinically, it can mimic a severe form of atopic dermatitis, psoriasiform dermatitis overlapping with atopic dermatitis, or erythrokeratodermia variabilis. The difficulties in making histological diagnosis are similar, and it is often necessary to take several biopsies in order to clarify the diagnosis. Although retinoids are used for both psoriasis, erythrokeratodermia variabilis, and other congenital forms of keratodermia, the recommended treatment doses are different. This often results in poor treatment outcome. We present a 16-year-old patient previously diagnosed as erythrokeratodermia variabilis and treated with little to no improvement. Systemic therapy with acitretin 10 mg daily, local pimecrolimus 1%, emollients, and bilastine 20 mg once daily was initiated. Due to the limited application of retinoids and the difficulties in achieving permanent remission, modern medicine is faced with the challenge of seeking innovative therapeutic solutions. New hopes are placed on targeted or anti-cytokine therapy, based on inhibiting the inflammatory component of the disease. This article is mainly focused on innovative therapeutic options, including modern medications such as dupilumab, infliximab, secukinumab, anakinra, omalizumab, and others.

Abstract
It is known that animal-origin medicine could be one of effective treatment to remedy atopic dermatitis (AD) by controlling the cytokines. Cicadidae Periostracum (CP), the slough of Cryptotympana pustulata, has been frequently used for treating AD and skin affliction in traditional Korean Medicine. This study is aimed at investigating the ameliorating effects of CP on AD and its potential mechanism. The dinitrochlorobenzene sensitized mice were treated with CP for 2 weeks. The various biomarkers and the dermatitis scores presented that CP treatment can induce the visual and biological improvements of AD model. Pruritus, the most serious symptom of AD, which can cause repeated scratching behaviors and finally lead to lichenification, was reduced with CP treatment by regulating the inflammatory reactions. In addition, CP treatment diminished the number of mast cells that are known for causing inflammatory reactions. Moreover, it is proven that CP can decline secretion of interleukin-22, which means CP treatment has anti-inflammatory effects. CP treatment can correct the imbalance of helper T (Th)1 and Th2, downregulating thymic stromal lymphopoietin that leads to decrease of mRNA level of inflammatory cytokines. The crucial role of CP treatment is controlling of the Janus kinase 1/signal transducer and activator of transcription 3 pathway. In addition, CP treatment has the inhibitory effects on kallikrein related peptidase (KLK) 5 and KLK7. Taken together, CP treatment can ameliorate most symptoms and problems caused by AD disease, improving the AD patients' life quality.

Heliyon 2023; 9:e16704. [PMID: 37332971 PMCID: PMC10272339 DOI: 10.1016/j.heliyon.2023.e16704] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2022] [Revised: 05/24/2023] [Accepted: 05/24/2023] [Indexed: 06/20/2023] Open
Abstract
Background The sparsity of head-to-head trials for medications used as in atopic dermatitis (AD) treatment makes therapy options difficult. Objective To better compare the efficacy and safety of abrocitinib and upadacitinib with dupilumab in patients with moderate-to-severe AD. Methods We systematically searched MEDLINE, EMBASE, and the Cochrane Library database for head-to-head trials. Results Three studies with 2256 patients were included. The analysis revealed that improvement of EASI-75 was rapidly registered with abrocitinib/upadacitinib as compared to the dupilumab, even as early as week 2 of treatment. The proportions of patients who reached the endpoint of EASI-75 at week 12 and end of therapy were also higher in the abrocitinib/upadacitinib group. Significant improvement in EASI-90 scores was demonstrated with abrocitinib/upadacitinib at week 2 and at all subsequent time points. The administration of abrocitinib/upadacitinib provided a faster onset of IGA response at week 2. The differences in IGA response remained significant at week 12 and end of therapy. Compared with dupilumab, a larger proportion of patients treated with abrocitinib/upadacitinib achieved early itch relief at 2 weeks. Better results were found later during treatment, in between the 12 weeks to the end of study in abrocitinib/upadacitinib group. The only observed significant result of adverse events were severe adverse events between the abrocitinib/upadacitinib group (n = 40) and the dupilumab group (n = 24) (p = 0.043). TEAEs of any causality that led to treatment discontinuation and serious adverse events have not shown special risks in the patients treated with abrocitinib/upadacitinib. Conclusions This study demonstrated that anti-JAK therapy, particularly abrocitinib and upadacitinib, exhibited superiority over dupilumab in achieving fast relief of disease signs with an acceptable safety profile in patients with moderate-to-severe atopic dermatitis.

Abstract
Atopic dermatitis is a chronic inflammatory skin disease with a significant impact on the overall wellbeing of patients and their families. Crisaborole ointment, 2%, is a nonsteroidal phosphodiesterase 4 inhibitor approved for the treatment of mild-to-moderate atopic dermatitis in multiple countries. However, in the key pivotal trials, a low proportion of the overall patient population was Asian, therefore the safety and efficacy of crisaborole in the Asian population with atopic dermatitis remains unclear. CrisADe CLEAR was a multicenter, randomized, double-blind, vehicle-controlled, phase 3 study (NCT04360187) to assess the efficacy and safety of crisaborole ointment in Chinese and Japanese patients aged ≥2 years with mild-to-moderate atopic dermatitis involving ≥5% treatable body surface area. Patients were randomly assigned 2:1 to receive crisaborole or vehicle twice daily for 28 days. The primary endpoint was percentage change from baseline in the Eczema Area and Severity Index total score at day 29. Additional endpoints were improvement and success per Investigator's Static Global Assessment score at day 29 and change from baseline on the Peak Pruritus Numerical Rating Scale at week 4. Safety was assessed using rates of treatment emergent adverse events, serious adverse events, and clinically significant changes in vital signs and clinical laboratory parameters. Crisaborole-treated patients showed a significantly greater reduction versus vehicle in percentage change from baseline in Eczema Area and Severity Index total score at day 29 (P = 0.0002). Response rates for achievement of Investigator's Static Global Assessment improvement and success at day 29 were significantly higher for patients treated with crisaborole versus vehicle (P = 0.0124 and P = 0.0078, respectively). Crisaborole-treated patients showed a significantly greater reduction versus vehicle in change from baseline on the Peak Pruritus Numerical Rating Scale at week 4 (P = 0.0009). No new safety signals were identified. Treatment with crisaborole was effective and well tolerated in Chinese and Japanese patients with mild-to-moderate atopic dermatitis.

Abstract
Atopic dermatitis (AD) is a common chronic inflammatory skin condition that has a significant impact on a patient's quality of life and requires ongoing management. Conventional topical and systemic therapies do not target specific components of AD pathogenesis and, therefore, have limited efficacy and may be associated with long-term toxicity. Thus, AD management is challenging, with a significant proportion of patients not achieving clear skin or a reduction in pruritus. There remains a large unmet need for effective therapeutic strategies with favorable safety profiles that can be used long-term in patients with refractory AD. The emergence of targeted biological and small molecule therapies has effectively broadened available treatment options for moderate-to-severe AD. Most recently, interleukin 13 (IL-13) inhibitors were shown to be efficacious and well-tolerated, with tralokinumab already approved for use in this patient population. It is important for dermatologists to be aware of the evidence behind this emerging class of biologic agents to guide treatment choices and improve outcomes in patients with AD. The main objective of this paper is to review the current literature regarding the efficacy and safety of current and emerging anti-IL-13 monoclonal antibodies, including tralokinumab, lebrikizumab, cendakimab, and eblasakimab, for the treatment of moderate-to-severe AD.

Abstract
Atopic dermatitis (AD), a pruritic, inflammatory chronic disease with multifactorial pathogenesis, has been a therapeutic challenge. Novel target treatments aim to reduce not only the immunologic dysfunction and microbiome dysbiosis but also the recovery of the damaged skin barrier. The current review focuses on the interleukin 31 (IL-31) pathway and AD and offers an overview of the current clinical studies with monoclonal antibodies blocking this cascade. Pruritus, the key symptom of AD, has substantial participation of the IL-31 complex and activation of relevant signaling pathways. Epidermal keratinocytes, inflammatory cells, and cutaneous peripheral nerves express the interleukin-31 receptor α-chain (IL-31RA), upregulated by Staphylococcus aureus toxins or Th2 cytokines involved in AD. Nemolizumab is a humanized monoclonal antibody that antagonizes IL-31RA, inhibiting the IL-31 cascade and therefore contributing to reducing the pruritus and inflammation and recovering the damaged skin barrier in AD patients. Phases 2 and 3 clinical trials with nemolizumab in AD show a suitable safety profile, with a fast, efficient, and sustained reduction of pruritus and severity scores, especially when associated with topical treatment. Deciphering the full interplay of the IL-31 pathway and AD may expand the potential of nemolizumab as a targeted therapy for AD and other pruritic conditions.

Abstract
In the last few decades, the prevalence of allergodermatoses in European countries, including the Russian Federation, has increased two to three times. The skin barrier plays an essential role in preventing the penetration of allergens and microbial agents into the human body.Atopic dermatitis is one of the most common, genetically determined skin diseases. The development of atopic dermatitis involves environmental factors that violate the skin barrier, as well as genetic, immunological features of the patient.In modern science, the issue of pathogenetic treatment of atopic dermatitis remains not fully resolved. The problem is complicated by the fact that this disease is multifactorial, with the dominance of IgE-mediated allergic reactions, although the level of IgE does not always correlate with the severity of atopic dermatitis.Currently, the development and implementation of genetically engineered drugs for the treatment of this pathology continues, one of such drugs is dupilumab.The article describes the efficacy and safety of the drug dupilumab in the treatment of severe continuously recurrent atopic dermatitis.Keywords: allergodermatoses, atopic dermatitis, severe continuously recurrent course, genetically engineered drugs, dupilumab.

Abstract
Atopic dermatitis (AD) is a chronic, relapsing inflammatory skin disease with a complex pathophysiology. Treatment of AD remains challenging owing to the presence of a wide spectrum of clinical phenotypes and limited response to existing therapies. However, recent genetic, immunological, and pathophysiological insights into the disease mechanism resulted in the invention of novel therapeutic drug candidates. This review provides a comprehensive overview of current therapies and assesses various novel drug delivery strategies currently under clinical investigation. Further, this review majorly emphasizes on various topical treatments including emollient therapies, barrier repair agents, topical corticosteroids (TCS), phosphodiesterase 4 (PDE4) inhibitors, calcineurin inhibitors, and Janus kinase (JAK)-signal transducer and activator of transcription (STAT) pathway inhibitors. It also discusses biological and systemic therapies, upcoming treatments based on ongoing clinical trials. Additionally, this review scrutinized the use of pharmaceutical inactive ingredients in the approved topical dosage forms for AD treatment.

Anti-Allergic Effects of Fermented Red Ginseng Marc on 2,4-Dinitrochlorobenzene-Induced Atopic Dermatitis-like Mice Model. APPLIED SCIENCES-BASEL 2022.

Abstract
Atopic dermatitis (AD) is a chronic and allergic skin disease; however, there is no cure for the disease. Red ginseng is well known to have anti-AD potential, while red ginseng marc (RGM) remaining after ginseng extraction is regarded as useless and discarded. However, it has recently been reported that RGM, particularly fermented RGM (fRGM), still contains bioactive properties. Thus, the anti-allergic effects of fRGM were examined in a 2,4-dinitrochlorobenzene-induced AD-like mice model. The model was topically treated with distilled water (control), dexamethasone, or fRGM for six weeks. Treatments of fRGM alleviated skin lesions and reduced serum IgE levels, compared with the control. The fRGM also reduced skin levels of lipid peroxidation and superoxide anion; however, it increased glutathione contents, with downregulated gene expression for inflammatory mediators. Histopathological analyses demonstrated that fRGM suppressed epidermal thickening, collagen deposition, and inflammatory cell and mast cell infiltration, which involved anti-inflammatory, antioxidant, and anti-apoptotic effects. Further, fRGM suppressed hypertrophic changes and inflammatory responses in the spleen and lymph nodes. The beneficial effects were observed in the dexamethasone and fRGM groups; however, the antioxidant effects were evident only in the fRGM treatments. These results provide useful information for developing fRGM as a therapeutic source for AD.

The evaluation of dupilumab treatment response in atopic dermatitis patients. North Clin Istanb 2021; 8:145-149. [PMID: 33851078 PMCID: PMC8039099 DOI: 10.14744/nci.2020.42375] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2020] [Accepted: 11/08/2020] [Indexed: 11/20/2022] Open
Abstract
OBJECTIVE: This study aims to demonstrate real-life effectiveness of dupilumab treatment in moderate-to-severe atopic dermatitis patients. METHODS: The 14 patients diagnosed with moderate-to-severe atopic dermatitis were included in this study. All of the patients started dupilumab treatment in our faculty between October 2019 and October 2020. The patients were evaluated at the beginning of the treatment and after 12 weeks of treatments. The baseline scoring atopic dermatitis (SCORAD) scores, the total immunoglobulin E (IgE) levels, and the visual analog scale (VAS) of 0–10 points for itch intensity compared with the post-treatment scores. RESULTS: The SCORAD scores, the serum total IgE levels, and the VAS itch scores of the patients receiving dupilumab treatment dropped significantly following 12 weeks of dupilumab treatment. No significant correlation was demonstrated between the initial SCORAD scores and the serum total IgE values. Besides, no correlation was shown to exist in the reduction of the SCORAD and the serum total IgE values after dupilumab treatment. CONCLUSION: Dupilumab treatment showed significant improvement in disease severity with remarkable reduction in serum total IgE levels.

Gonçalves F, Freitas E, Torres T. Selective IL-13 inhibitors for the treatment of atopic dermatitis. Drugs Context 2021; 10:dic-2021-1-7. [PMID: 33889195 PMCID: PMC8015935 DOI: 10.7573/dic.2021-1-7] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2021] [Accepted: 02/26/2021] [Indexed: 12/19/2022] Open
Abstract
Background Atopic dermatitis (AD) is one of the most common chronic inflammatory skin diseases worldwide. AD pathogenesis is multifactorial, involving environmental and genetic factors. IL-13 stands out as one of the main cytokines in the pathophysiology of AD. Currently, dupilumab, which targets both IL-4 and IL-13 signalling, is the only biologic agent approved for the treatment of moderate-to-severe AD. New targeted biologic therapies are being developed, such as lebrikizumab and tralokinumab, two selective IL-13 inhibitors. This article reviews the role of IL-13 in AD and the most recent data on lebrikizumab and tralokinumab. Methods A narrative review of the literature was written after retrieving relevant articles in the PubMed database (up until December 2020) using the following keywords present in the title, abstract or body: atopic dermatitis; interleukin 13; IL-13; tralokinumab; lebrikizumab, biologic therapy. Discussion A phase IIb trial showed that all three dosing regimens evaluated (lebrikizumab 125 mg every 4 weeks (Q4W), 250 mg Q4W or 250 mg every 2 weeks) achieved rapid and dose-dependent efficacy concerning the signs and symptoms of AD, with a statistically significant improvement, at week 16. Tralokinumab was studied in three phase III clinical trials and reached its primary endpoints at week 16 (ECZTRA 1 and 2 in monotherapy and ECZTRA 3 with concomitant topical corticosteroids), with response maintained over time. Both lebrikizumab and tralokinumab exhibited good safety profiles in AD trials, with adverse effects usually being comparable between the control and treatment groups. Conclusion The evidence supports the hypothesis that selective antagonism of IL-13 is sufficient to control AD, providing an improvement in the patient’s quality of life. Therefore, the development of lebrikizumab and tralokinumab represents a new and exciting phase in the management of AD.

Abstract
In recent years, the published literature has suggested the key involvement of the cytokine interleukin-31 (IL-31) in the symptomatology of pruritus, and both IL-31 and its receptor have become potential therapeutic targets for a range of pruritic diseases. Elevated levels of IL-31 or its receptor have been reported in the tissue or serum of patients with pruritic skin diseases, such as atopic dermatitis, prurigo nodularis, and psoriasis. Pruritus places a heavy burden on patients, and can have a negative impact on daily life, sleep, and mental health. Since current anti-pruritic treatments are often ineffective, affected patients are in urgent need of new therapies. As a result, drug development targeting the IL-31 pathway is evolving rapidly. To date, only nemolizumab, a humanized monoclonal antibody targeting the IL-31 receptor, has successfully completed late-stage clinical studies. This article will highlight our current clinical understanding of the role of IL-31 in pruritic disease, and explore recent progress in drug development as well as the anticipated future advances in this field.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2021; 82:153453. [PMID: 33450637 DOI: 10.1016/j.phymed.2020.153453] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/22/2020] [Revised: 12/22/2020] [Accepted: 12/24/2020] [Indexed: 06/12/2023]
Abstract
BACKGROUND Dictamni Cortex (DC), a Chinese herbal medicine with wind dispelling and itchiness relieving effects, is the most popular single herb prescribed for the treatment of atopic dermatitis (AD), as it is used in up to 12.68% of all herbal prescriptions for AD. PURPOSE The present study aimed to evaluate the anti-AD effect of Dictamni Cortex extract (DCE) and elucidate the underlying molecular mechanisms of its action using the 1-chloro-2,4-dinitrobenzene (DNCB)-induced AD-like mouse model and a relevant in vitro experimental model. METHODS Female Balb/c mice were sensitized with 200 μl 0.5% DNCB for three days. After sensitization, mice were challenged with 200 μl 1% DNCB on the same dorsal skin and also 20 μl 1% DNCB on each ear every 3 days, and orally administrated by gavage with DCE (0.6, 1.2 and 2.4 g/kg) daily from day 14 to day 29 for 16 consecutive days. At the end of experiment, the clinical scores for AD on the mice were calculated to evaluate the therapeutic effect of DCE; and serum, ears and dorsal skin of the mice were collected for mechanistic study. The anti-allergic activity of DCE was also evaluated using antigen-induced RBL-2H3 cell line. The release of selected cytokines, chemokines and β-hexosaminidase was measured to determine the anti-allergic activity of DCE. In addition, intracellular Ca2+ level, MAPKs and Lyn phosphorylations were further investigated to reveal its anti-allergic molecular mechanisms. RESULTS Our results demonstrated that DCE could markedly improve the AD-like symptoms in AD-like mice by inhibiting the mast cell infiltration, suppressing the production of Th2-associated cytokine (IL-4) and pro-inflammatory cytokines (TNF-α), and enhancing the protein expression of filaggrin through inhibition of the MAPKs and NF-κB pathways. Moreover, DCE suppressed mast cell degranulation through decreasing the intracellular Ca2+ level and inactivation of Lyn, Syk and PLCγs, suggesting DCE could regulate mast-cell-mediated allergic response. CONCLUSION Our experimental results unambiguously indicate that DCE possesses potent anti-allergic effect, and help place the application of DC for the treatment of AD on a scientific footing.

Murata S, Kaneko S, Morita E. Interleukin-8 Levels in the Stratum Corneum as a Biomarker for Monitoring Therapeutic Effect in Atopic Dermatitis Patients. Int Arch Allergy Immunol 2021; 182:592-606. [PMID: 33486487 DOI: 10.1159/000512965] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2020] [Accepted: 11/09/2020] [Indexed: 01/06/2023] Open
Abstract
INTRODUCTION The stratum corneum contains several growth factors and cytokines that are synthesized in keratinocytes. We previously reported that the amount of interleukin-8 in the stratum corneum (scIL-8) is related to the severity of local skin inflammation in atopic dermatitis (AD). However, it is unknown whether scIL-8 levels reflect pharmacologic responses to a therapeutic intervention in AD patients. Therefore, in this study, we aimed to investigate whether the improvement of dermatitis in AD is correlated with scIL-8 levels before and after topical corticosteroid treatment. METHODS Stratum corneum samples were collected from 22 AD patients using the noninvasive tape-stripping method before treatment, 2 weeks after topical treatment, and 4-6 weeks after treatment. RESULTS scIL-8 levels on the forearm reduced significantly from 790 ± 348 pg/mg before treatment to 163 ± 68 pg/mg 2 weeks after treatment and 100 ± 37 pg/mg 4-6 weeks after corticosteroid treatment. scIL-8 levels on the abdomen also reduced significantly from 902 ± 391 to 142 ± 38 pg/mg at the end of study. The reduction in scIL-8 levels was associated with the improvement in local skin severity in AD. We also found that scIL-8 levels, along with blood biomarker levels (serum thymus and activation-regulated chemokine, lactate dehydrogenase, and %eosinophil), decreased significantly after the treatment. CONCLUSION The scIL-8 concentration decreases with improvements in skin symptoms in AD patients after topical corticosteroid treatment; thus, it may be a suitable biomarker for monitoring therapeutic effects in AD patients.

Cicadidae Periostracum Attenuates Atopic Dermatitis Symptoms and Pathology via the Regulation of NLRP3 Inflammasome Activation. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2021; 2021:8878153. [PMID: 33520088 PMCID: PMC7817262 DOI: 10.1155/2021/8878153] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/06/2020] [Revised: 09/03/2020] [Accepted: 12/01/2020] [Indexed: 01/27/2023]
Abstract
Atopic dermatitis (AD) is a multifactorial inflammatory skin disease of complex etiology. Despite its increasing prevalence, treatment for AD is still limited. Crude drugs, including herbal extracts or natural resources, are being used to treat AD symptoms, with minimum side effects. Cicadidae Periostracum (CP), derived from the slough of insects belonging to the family Cicadidae, is a commonly used crude drug in traditional Asian medicine to treat/control epilepsy, shock, and edema. However, the effect of CP on AD-like skin lesions is unknown. In this study, we examined the effect of a CP water extract on AD disease development in vivo, using a house dust mite-induced AD mouse model, and in vitro, using HaCaT keratinocytes and a 3D human skin equivalent system. Importantly, CP administration alleviated house dust mite-induced AD-like symptoms, suggested by the quantified dermatitis scores, animal scratching behaviors, skin moisture retention capacity, and skin lesion and ear thickness. Furthermore, histopathological analysis demonstrated that CP decreased intralesional mast cell infiltration. In addition, CP treatments decreased the systemic levels of immunoglobulin E, histamine, and thymic stromal lymphopoietin (TSLP) and the local mRNA expression of TSLP and several Th1/Th2 cytokines. Our data suggest that these effects were mediated by the inhibition of nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome activation. In vivo and in vitro CP treatments resulted in the downregulation of inflammasome components, such as ASC and cleaved caspase-1, as well as related mediators such as IL-1β and reactive oxygen species. Collectively, our results suggest that CP is a potential therapeutic agent for AD, controlling inflammatory responses through the suppression of NLRP3 inflammasome activation.

Abstract
Atopic dermatitis (AD) is a chronic relapsing inflammatory skin disease. Systemic treatment is usually mandatory in moderate-to-severe AD of the adult; these patients need to be informed about safe and effective management of AD also regarding the reproduction. Treating a pregnant woman with AD with systemic drugs may affect the unborn child. While effects of traditional systemic treatments for AD on female fertility, pregnancy, and breastfeeding are largely known, data about new emergent therapies for AD are still poor. Treating pregnant or lactating women with AD can be a challenge since no large clinical studies on its possible effects and side-effects on conception, pregnancy, the unborn child and lactation are currently available for new AD treatments.

Abstract
Background Following the first investigational study on the use of extracorporeal photopheresis for the treatment of cutaneous T‐cell lymphoma published in 1983, this technology has received continued use and further recognition for additional earlier as well as refractory forms. After the publication of the first guidelines for this technology in the JEADV in 2014, this technology has maintained additional promise in the treatment of other severe and refractory conditions in a multidisciplinary setting. It has confirmed recognition in well‐known documented conditions such as graft‐vs.‐host disease after allogeneic bone marrow transplantation, systemic sclerosis, solid organ transplant rejection including lung, heart and liver and to a lesser extent inflammatory bowel disease. Materials and methods In order to further provide recognized expert practical guidelines for the use of this technology for all indications, the European Dermatology Forum (EDF) again proceeded to address these questions in the hands of the recognized experts within and outside the field of dermatology. This was done using the recognized and approved guidelines of EDF for this task. All authors had the opportunity to review each contribution as it was added. Results and conclusion These updated 2020 guidelines provide at present the most comprehensive available expert recommendations for the use of extracorporeal photopheresis based on the available published literature and expert consensus opinion. The guidelines were divided into two parts: PART I covers Cutaneous T‐cell lymphoma, chronic graft‐vs.‐host disease and acute graft‐vs.‐host disease, while PART II will cover scleroderma, solid organ transplantation, Crohn’s disease, use of ECP in paediatric patients, atopic dermatitis, type 1 diabetes, pemphigus, epidermolysis bullosa acquisita and erosive oral lichen planus.

Abstract
BACKGROUND Eczema is a common and chronic, relapsing, inflammatory skin disorder. It seriously impacts quality of life and economic outcomes, especially for those with moderate to severe eczema. Various treatments allow sustained control of the disease; however, their relative benefit remains unclear due to the limited number of trials directly comparing treatments. OBJECTIVES To assess the comparative efficacy and safety of different types of systemic immunosuppressive treatments for moderate to severe eczema using NMA and to generate rankings of available systemic immunosuppressive treatments for eczema according to their efficacy and safety. SEARCH METHODS We searched the following databases up to August 2019: the Cochrane Skin Specialised Register, CENTRAL, MEDLINE, and Embase. SELECTION CRITERIA All randomised controlled trials (RCTs) of systemic immunosuppressive agents for moderate to severe atopic eczema when compared against placebo or any other eligible eczema treatment. DATA COLLECTION AND ANALYSIS We synthesised data using pair-wise analysis and NMA to compare treatments and rank them according to their effectiveness. Effectiveness was assessed primarily by determining the proportion of participants who achieved at least 75% improvement in the Eczema Area and Severity Index (EASI75) and improvement in the Patient-Oriented Eczema Measure (POEM). Safety was evaluated primarily by considering the proportion of participants with serious adverse events (SAEs) and infection. We deemed short-term follow-up as ≤ 16 weeks and long-term follow-up as > 16 weeks. We assessed the certainty of the body of evidence from the NMA for these primary outcomes using six domains of CiNEMA grading. MAIN RESULTS We included a total of 74 studies, with 8177 randomised participants. Approximately 55% of participants were male, with average age of 32 years (range 2 to 84 years), although age and gender were unreported for 419 and 902 participants, respectively. Most of the included trials were placebo controlled (65%), 34% were head-to-head studies (15% assessed the effects of different doses of the same drug), and 1% were multi-armed studies with both an active comparator and a placebo. All trials included participants with moderate to severe eczema, but 62% of studies did not separate data by severity; 38% of studies assessed only severe eczema. The total duration of included trials ranged from 2 weeks to 60 months, whereas treatment duration varied from a single dose (CIM331, KPL-716) to 60 months (methotrexate (MTX)). Seventy studies were available for quantitative synthesis; this review assessed 29 immunosuppressive agents from three classes of interventions. These included (1) conventional treatments, with ciclosporin assessed most commonly; (2) small molecule treatments, including phosphodiesterase (PDE)-4 inhibitors, tyrosine kinase inhibitors, and Janus kinase (JAK) inhibitors; and (3) biological treatments, including anti-CD31 receptors, anti-interleukin (IL)-22, anti-IL-31, anti-IL-13, anti-IL-12/23p40, anti-OX40, anti-TSLP, anti-CRTH2, and anti-immunoglobulin E (IgE) monoclonal antibodies, but most commonly dupilumab. Most trials (73) assessed outcomes at a short-term duration ranging from 2 to 16 weeks, whereas 33 trials assessed long-term outcomes, with duration ranging from 5 to 60 months. All participants were from a hospital setting. Fifty-two studies declared a source of funding, and of these, pharmaceutical companies funded 88%. We rated 37 studies as high risk; 21, unclear risk, and 16, low risk of bias, with studies most commonly at high risk of attrition bias. Network meta-analysis suggests that dupilumab ranks first for effectiveness when compared with other biological treatments. Dupilumab is more effective than placebo in achieving EASI75 (risk ratio (RR) 3.04, 95% confidence interval (CI) 2.51 to 3.69) and improvement in POEM score (mean difference 7.30, 95% CI 6.61 to 8.00) at short-term follow-up (high-certainty evidence). Very low-certainty evidence means we are uncertain of the effects of dupilumab when compared with placebo, in terms of the proportion of participants who achieve EASI75 (RR 2.59, 95% CI 1.87 to 3.60) at longer-term follow-up. Low-certainty evidence indicates that tralokinumab may be more effective than placebo in achieving short-term EASI75 (RR 2.54, 95% CI 1.21 to 5.34), but there was no evidence for tralokinumab to allow us to assess short-term follow-up of POEM or long-term follow-up of EASI75. We are uncertain of the effect of ustekinumab compared with placebo in achieving EASI75 (long-term follow-up: RR 1.17, 95% CI 0.40 to 3.45; short-term follow-up: RR 0.91, 95% CI 0.28 to 2.97; both very low certainty). We found no evidence on ustekinumab for the POEM outcome. We are uncertain whether other immunosuppressive agents that targeted our key outcomes influence the achievement of short-term EASI75 compared with placebo due to low- or very low-certainty evidence. Dupilumab and ustekinumab were the only immunosuppressive agents evaluated for longer-term EASI75. Dupilumab was the only agent evaluated for improvement in POEM during short-term follow-up. Low- to moderate-certainty evidence indicates a lower proportion of participants with SAEs after treatment with QAW039 and dupilumab compared to placebo during short-term follow-up, but low- to very low-certainty evidence suggests no difference in SAEs during short-term follow-up of other immunosuppressive agents compared to placebo. Evidence for effects of immunosuppressive agents on risk of any infection during short-term follow-up and SAEs during long-term follow-up compared with placebo was of low or very low certainty but did not indicate a difference. We did not identify differences in other adverse events (AEs), but dupilumab is associated with specific AEs, including eye inflammation and eosinophilia. AUTHORS' CONCLUSIONS Our findings indicate that dupilumab is the most effective biological treatment for eczema. Compared to placebo, dupilumab reduces eczema signs and symptoms in the short term for people with moderate to severe atopic eczema. Short-term safety outcomes from clinical trials did not reveal new safety concerns with dupilumab. Overall, evidence for the efficacy of most other immunosuppressive treatments for moderate to severe atopic eczema is of low or very low certainty. Given the lack of data comparing conventional with newer biological treatments for the primary outcomes, there remains high uncertainty for ranking the efficacy and safety of conventional treatments such as ciclosporin and biological treatments such as dupilumab. Most studies were placebo-controlled and assessed only short-term efficacy of immunosuppressive agents. Further adequately powered head-to-head RCTs should evaluate comparative long-term efficacy and safety of available treatments for moderate to severe eczema.

Abstract
Cytokines predominate the inflammatory pathways in diseases like rhinitis, asthma, and atopic dermatitis. Corticosteroids and immunosuppressants are presently the mainstays of treatment for patients with moderate-to-severe disease, but often accompany a poor side effect profile. In this review, we attempt to consolidate current data on various interleukins (IL) that participate in the pathogenesis of atopic dermatitis (AD) to further improve therapeutic strategies. For now, dupilumab is the most accepted biologic to be registered for treatment for moderate-to-severe disease. Recently, IL-37, IL-13, IL-26, IL-17 & IL-31/33 axis as well as proteins like thymic stromal lymphopoietin (TSLP) show promising results as future therapeutic targets because of their important role in the pathogenesis of AD. However, further studies are required to clarify the safety and efficacy of these interventions compared to current treatment modalities but it is worthwhile to pursue research into biologics as a more successful treatment option for moderate-to-severe AD.

Abstract
INTRODUCTION Atopic dermatitis (AD) is a chronic inflammatory skin disease mediated by multiple signals including janus kinase (JAK)/signal transducer and activator of transcription (STAT) pathway. Current therapeutic armamentarium consists of a limited number of drugs which may result in the insufficient management of AD. Preclinical evidence regarding inhibition of JAK/STAT led to the development of a promising class of therapeutics, namely, JAK inhibitors. Baricitinib, a novel JAK1/JAK2 inhibitor is currently under investigation in AD clinical trials. AREAS COVERED This review offers an overview of Baricitinib and examines clinical efficacy and safety data in patients with moderate-to-severe AD. EXPERT OPINION Baricitinib showed promising preliminary data in terms of efficacy in phase II and III trials, with a very rapid onset of response and great improvements of itch and sleep disturbances. These aforementioned aspects combined with the advantage of an oral formulation have reduced drug production costs compared to biologic agents and could lead to consideration of baricitinib as a first line systemic treatment. Also, in some countries, it could be a therapeutic option in the case of contraindication or failure of conventional systemic drugs prior to biologic therapies. Data related to long-term safety and efficacy will be important to refine the place-in-therapy of this drug.

Abstract
Atopic dermatitis (AD) is generally considered a T helper type 2-dominated disease. Pediatric AD is usually less severe than adult AD, but it may present as moderate to severe lesions that are inadequately managed by current modalities including emollients/moisturizers, topical corticosteroids (TCSs), topical calcineurin inhibitors (TCIs), and even systemic immunosuppressants (such as cyclosporine, azathioprine, methotrexate, and mycophenolate mofetil). In addition, systemic immunosuppressants are often not recommended for childhood AD by the current guidelines due to their toxicities. Therefore, there is still an unmet need for a safe and effective long-term therapy for pediatric AD patients whose disease is inadequately controlled or who are intolerant to current treatments. The emerging therapeutics for AD focuses on intervening in the inflammatory pathway by targeting specific cytokines/chemokines or their receptors. Monoclonal antibodies against immunoglobulin E (IgE), interleukin (IL)-4 receptor subunit α, IL-5, IL-13, IL-31 receptor subunit α, IL-33, and thymic stromal lymphopoietin (TSLP) have been evaluated clinically for AD. Encouraging results have been reported for many of the biologics, of which the most exciting is dupilumab. Other emerging systemic therapies include small molecules such as baricitinib, abrocitinib, upadacitinib, and tradipitant. Several novel topical agents are under clinical investigation for the treatment of AD, including topical phosphodiesterase 4 (PDE4) inhibitors, Janus kinase (JAK) inhibitors, aryl hydrocarbon receptor (AhR) modulating agents, and transient receptor potential vanilloid subfamily member 1 (TRPV1) antagonists. Accompanied by thorough characterization of different phenotype and endotype subsets, the application of precision medicine could provide new prospects for the optimal treatment of AD.

Abstract
INTRODUCTION Moderate-to-severe AD burdens a large proportion of AD patients and may represent an inadequacy of treatment options available for resistant disease. AREAS COVERED This review provides an overview of the therapies for moderate-to-severe AD in late-stage development and in the clinic, and focuses on baricitinib as an emerging therapeutic option. Baricitinib is an orally available selective JAK1/JAK2 inhibitor that is approved for use in the treatment of moderate-to-severe rheumatoid arthritis (RA). Baricitinib decreases AD lesions, disease severity, and improves quality of life. Overall, the small molecule inhibitor is well tolerated. However, its black-box warnings in the RA population raise a concern for its long-term safety. EXPERT OPINION Baricitinib is a promising treatment modality for moderate-to-severe AD. Its primary advantage over dupilumab, the revolutionary biologic agent approved for AD, is that patients prefer an oral medication over an injection. However, providers will likely prescribe an injectable over an oral medication if baricitinib has an unfavorable safety profile. Insurance coverage of baricitinib will also have a major role in clinical use. Baricitinib will likely face competition from other JAK inhibitors in the future; however, it will have an advantage if it becomes the first FDA-approved medication of its kind for resistant AD.

Abstract
Atopic dermatitis (AD) is the most common chronic cutaneous inflammatory disease of childhood, affecting up to 25% of children; its prevalence in adulthood is currently unknown, since studies reported that AD may affect 0.3-14.3% of adult population. In the last decade, the advanced understanding of AD molecular pathways along with patient's and physician's demand for more effective therapies, led to the introduction of new therapeutic agents. Baricitinib is an oral JAK inhibitor highly selective for JAK1 and JAK2. Treatment with baricitinib improved the signs and symptoms of moderate-to-severe AD compared to placebo, but it will be essential to better understand the safety profile of this drug.

Abstract
Background: Atopic dermatitis is a chronic inflammatory skin disease that remarkably affects the quality-of-life of patients. Chamomile oil is used to treat skin inflammations. We evaluated the efficacy of chamomile oil and nanoemulgel formulations as a natural alternative therapeutic option for atopic dermatitis.Research design and methods: Formulations were developed comprising chamomile oil: olive oil (1:1), Tween 20/80 or Gelucire 44/14 as surfactant-cosurfactant mixtures, propylene glycol (10%w/w), water and hydroxypropyl methylcellulose (3%w/w). In-vitro physicochemical characterization, stability testing and in-vivo assessment of inflammatory biomarkers and histopathological examination of skin lesions were conducted in rats induced with atopic dermatitis.Results: Nanoemulgels G1 and X1 which displayed the smallest particle size of 137.5 ± 2.04 and 207.1 ± 5.44 nm, good homogeneity and high zeta-potential values of -26.4 and -32.7 mV were selected as the optimized emulgel. Nanoemulgels were nonirritating of pH value 5.56, readily spreadable, and were physically stable following 10 heating-cooling cycles. Treatment with nanoemulgels showed a two-fold decrease in duration of skin healing and no spongiosis compared to chamomile oil. Levels of biomarkers were reduced after topical application of both nanoemulgels and chamomile oil.Conclusion: Nanoemulgels are a potential cost effective, safe topical carrier system for chamomile in treating atopic dermatitis.

Abstract
Recent data support the theory of the involvement of IL‐17 in the pathogenesis of several chronic inflammatory skin diseases (psoriasis, atopic dermatitis, acne, hidradenitis suppurativa) and autoimmune skin diseases (alopecia areata, vitiligo, bullous diseases). Even if the role of IL‐17 in inflammatory and autoimmune diseases has been reported extensively, its role in tumor is still controversial. Some reports show that Th17 cells eradicate tumors, while others reveal that they promote the initiation and early growth of tumors. Herein, we review the role of IL‐17 in the involvement of some common dermatologic diseases: psoriasis, atopic dermatitis, hidradenitis suppurativa, acne, vitiligo, melanoma, and nonmelanoma skin cancers.

Abstract
Leukotrienes (LTs) are lipid mediators that play pivotal roles in acute and chronic inflammation and allergic diseases. They exert their biological effects by binding to specific G-protein-coupled receptors. Each LT receptor subtype exhibits unique functions and expression patterns. LTs play roles in various allergic diseases, including asthma (neutrophilic asthma and aspirin-sensitive asthma), allergic rhinitis, atopic dermatitis, allergic conjunctivitis, and anaphylaxis. This review summarizes the biology of LTs and their receptors, recent developments in the area of anti-LT strategies (in settings such as ongoing clinical studies), and prospects for future therapeutic applications.

Abstract
Atopic dermatitis (AD) is a complex disease that is thought to be triggered by environmental factors in genetically susceptible individuals. Twin studies have estimated the heritability of AD to be approximately 75%, with the null (loss-of-function) mutations of the gene encoding filaggrin (FLG) (chromosome 1q21.3) as the strongest known genetic risk factor. The discovery of the filaggrin gene was important in the emerging model for AD pathogenesis, combining skin barrier function with adaptive and innate immunity. Assisted by the recent development of large-scale high-throughput genomics, more than 30 genetic loci have been linked to AD across different populations. Identification of these loci, together with functional studies, has already provided new insights into disease biology and identified novel drug targets. Further, these susceptibility loci are laying the groundwork for phenome-wide association studies to test their multiple phenotype relationships and application of Mendelian randomization to investigate causal relationships. Despite many known genes, a majority of the genetic risk for AD is yet unexplored. Therefore, studies investigating refined phenotype groups, low-frequency and rare genetic variation, gene-gene and/or gene-environment interactions, epigenetic mechanisms and data from multi-omics technologies are warranted. In this review, we describe genetic discoveries for AD, including results from candidate gene studies, studies of AD-like genetic diseases, genome-wide association studies and genetic sequencing studies. We explain how some of these genetic discoveries have unraveled new mechanistic insights into the pathogenesis of AD and exemplify how personal genetic data could be used for preventive strategies and a tailored treatment regimen (i.e., precision medicine).

Abstract
Atopic dermatitis (AD) is a common, chronic, relapsing-remitting inflammatory disease that can be challenging to treat. Patients with mild disease are usually managed well with good skin care practices including moisturization and appropriate bathing along with intermittent use of topical therapies such as topical corticosteroids and/or topical calcineurin inhibitors during flares. Patients with frequent flares may benefit from proactive application of topical therapies twice a week to the most troublesome areas. Patients with severe disease often present significant treatment challenges. Systemic therapies are usually required for severe AD but have varying degrees of success and can be associated with side-effect profiles that require counseling and close monitoring. Phototherapy has been shown to have success in treating moderate-to-severe AD, but several factors can limit its utility and efficacy including cost and access. New therapies are in development targeting specific pathways relevant for AD. Dupilumab was the first biologic treatment approved in North America, Europe, and Japan for adults with moderate-to-severe AD. Although this treatment can lead to rapid improvement in the majority of patients, there are inadequate responders. In this review, we discuss the clinical challenges and treatment options for moderate-to-severe refractory AD.

Abstract
Background: Treatment of atopic dermatitis (AD) may be challenging, therefore some patients seek complementary and alternative medications (CAM). We determined prevalence and predictors for CAM use in a hospital cohort of AD patients. Material and Methods: Between January 1, 2012, and December 31, 2017, AD patients referred to the dermatological outpatient clinic at Bispebjerg Hospital were included in the study. Information on CAM use, demographics and disease characteristics were obtained by questionnaire, and associations were determined by χ2 and t test separately for children (< 16 years) and adults (≥16 years). Results: In total 441 filled in the questionnaire on AD, and 433 patients responded to the questions about CAM use: 198 children and 235 adults. A total of 137 (31.6%) had used one or more CAM. CAM use in children was significantly associated with prior use of ≥2 conventional treatments (p = 0.047) and topical calcineurin inhibitors (p = 0.021), a higher number of affected eczema sites (p < 0.001) including more frequent affection of the face and extremities, a higher SCORAD score (p = 0.045), and low mean overall self-rated health (p = 0.003). CAM use in adults was significantly associated with lower age of onset of AD (p = 0.004), comorbid allergic rhinoconjunctivitis (p = 0.039), frequent use of moisturizing cream (p = 0.024), facial and neck eczema (p = 0.005) and high educational level (p = 0.043). Conclusion: CAM use is frequent in both children and adult AD patients. CAM users are characterized by long disease duration, a significant disease burden and by having a longer education. The high prevalence of CAM may indicate that patients’ expectations regarding treatment of AD are not redeemed in the conventional health care system.

Abstract
Atopic dermatitis (AD) is an inflammatory, pruritic, chronic or chronically relapsing skin disease that typically begins in early childhood and is occurring frequently in families with other atopic diseases (bronchial asthma and/or allergic rhino-conjunctivitis). Thanks to immunological and neurobiological research, the era of new treatments is coming as well as it occurred with psoriasis 15 years ago. Many treatments targeting cytokines (IL-4, IL-13, IL-31, TSLP) or neurotransmitters (substance P, opioids) or their respective receptors as well as phosphodiesterase-4 or the Jak/Stat pathways are under development. Antagonists of cytokines and anti-jak have promising effects on pruritus while it is more difficult to discriminate the effects of other drugs from the placebo effect on itch, which is known to be high.

Abstract
INTRODUCTION Atopic dermatitis (AD) is one of the most common childhood skin disorders. Multiple mechanisms contribute to the pathology of AD and treatment approaches are directed at these processes. AREAS COVERED The purpose of this review is to discuss the chemical treatment options for pediatric atopic dermatitis, including immunomodulators and small molecule inhibitors. A systematic literature search was conducted, and publications were reviewed for applicable treatment guidelines. EXPERT OPINION Topical therapy is first-line for pediatric atopic dermatitis. Providers should work closely with patients and caregivers to promote the success of topical treatments. In disease refractory to topical treatments, systemic agents may be considered. Clinical trials are ongoing for the use of biologics in the treatment of pediatric AD. When choosing the most appropriate treatment, physicians should consider the drug efficacy, potential adverse effects, patient adherence, and quality of life for both patients and caregivers. Additional studies are required to determine the safest and most effective doses for systemic therapy in childhood AD.

Abstract
Atopic dermatitis (AD) is a recurrent, chronic, and inflammatory skin disease, which processes with severe itchiness. It often coexists with different atopic diseases. The number of people suffering from AD is relatively high. Epidemiological research demonstrates that 15–30% of children and 2–10% adults suffer from AD. The disease has significant negative social and economic impacts, substantially decreasing the quality of life of the patients and their families. Thanks to enormous progress in science and technology, it becomes possible to recognise complex genetic, immunological, and environmental factors and epidermal barrier defects that play a role in the pathogenesis of AD. We hope that the new insight on cytokines in AD will lead to new, individualised therapy and will open different therapeutic possibilities. In this article, we will focus on the cytokines, interleukin (IL)-17, IL-19, IL-33, and TSLP (thymic stromal lymphopoietin), which play a significant role in AD pathogenesis and may become the targets for future biologic therapies in AD. It is believed that the new era of biological drugs in AD will give a chance for patients to receive more successful treatment.

Abstract
Atopic dermatitis (AD) is a bothersome and common skin disease affecting ∼10.7% of children in the United States. This skin condition significantly decreases quality of life in not only patients, but in their families as well. Pediatricians are often the first physicians to diagnose and manage these patients and thus are relied on by families to answer questions about this disease. AD is complex, multifactorial, and has historically had limited therapeutic options, but the landscape of this disease is now rapidly changing. Pathways contributing to the pathogenesis of this disease are continually being discovered, and new therapies for AD are being developed at an unprecedented rate. With this article, we will review the current guidelines regarding the management of AD, outline updates in the current understanding of its pathophysiology, and highlight novel developments available for the treatment of this burdensome disease.

Abstract
INTRODUCTION Adult atopic dermatitis (AD) is very difficult to manage. Indeed, AD in adults is frequently refractory to topical treatment, especially with regards to the persistent form. Therefore, long-term treatment with oral immunosuppressive therapy is often required to control the burden of the disease, prevent flare-ups and achieve better patient quality of life outcomes. Areas covered: In the last decade the better understanding of AD pathogenesis has been used to improve treatment strategies with many emerging therapeutics options. Epidermal barrier impairment often plays the initial role in the initiation of the disease. Moreover, T helper 2 cytokines interleukin (IL)-4 and IL-13 and their downstream effects are prominent in AD, with pleiotropic effects on the innate and adaptive immune system. Targeting these cells, their products or receptors appears to be a reasonable therapeutic strategy. Expert commentary: In the next years, many therapeutic options for adult AD will be available. Clinical trials showed that JAK inhibitors, PDE-4 inhibitors and monoclonal antibodies against some IL (IL-4, IL 13, IL-17, IL-22, IL-31) seem to be the most promising drugs, but dermatologists will have to evaluate their effectiveness and safety in clinical practice.

Abstract
Dupilumab (Dupixent®), a subcutaneously administered, fully human IgG4 monoclonal antibody directed against the IL (interleukin)-4 receptor α subunit, blocks the signalling of IL-4 and IL-13, two T helper cell type 2 cytokines implicated in the immunopathology of atopic dermatitis (AD). It is the first biologic therapy to have been approved for the treatment of adult patients with moderate-to-severe AD in the EU and USA. In phase III trials in adults with moderate-to-severe AD who were inadequately controlled with topical medications and/or systemic treatments, such as ciclosporin, or for whom these therapies were not advisable, 16 weeks' treatment with dupilumab as monotherapy or in combination with topical corticosteroids (TCS) improved multiple measures of disease severity, pruritus, sleep disturbance, anxiety and depression, and quality of life compared with placebo. Moreover, the benefits of combination therapy at week 16 were maintained during long-term treatment for up to 1 year. Dupilumab, alone or added to TCS, was generally well tolerated, with low rates of serious adverse events and treatment discontinuations due to adverse events. Common adverse reactions included conjunctivitis, injection-site reactions and oral herpes. Thus, dupilumab represents a valuable new treatment option for adults with moderate-to-severe AD deemed appropriate for systemic therapy, a patient population for whom historically there has been a lack of safe and effective long-term treatments.
