Atopic dermatitis (AD) is an inflammatory skin disease characterized by chronic recurrent dermatitis with profound itching. Most patients have personal and/or family history of atopic diseases. Several criteria have been proposed for the diagnosis of AD. Although the clinical features of childhood AD have been widely studied, there has been less large-scale study on adult/adolescent AD. The aim of this study was to investigate the clinical features of adult/adolescent patients with chronic symmetrical eczema/AD and to propose Chinese diagnostic criteria for adult/adolescent AD.

Atopic dermatitis is a common chronic/chronically relapsing inflammatory skin disease, with increasing worldwide prevalence. Etiopathogenesis is complex and multifactorial, with a mix of genetic, immunological and environmental aspects. Like in other chronic inflammatory diseases, oxidative stress plays an important pathogenetic role. We reviewed in vivo research studies on humans about oxidative stress and atopic dermatitis. Although sometimes contrasting, overall, they suggest that oxidative stress may have a significant role in atopic dermatitis, but our understanding is still incomplete, at least concerning in vivo data, because of limitations of available literature. Research consists of 33 papers published in 28 years, was not always performed on large study populations, represents a limited number of countries and ethnicities-not always in proportion to their size-and is scattered over multiple papers that, in the majority of cases, cannot be pooled and/or compared because many biomarkers were studied, in different tissues and with different methods. Further, larger studies appear warranted and necessary to shed more light on this aspect of atopic dermatitis, which is important not only to improve our understanding of this disease, but also for potential clinical and therapeutic implications.

Atopic dermatitis (AD) can be subclassified into the more frequent extrinsic type (EAD), with elevated serum IgE levels and frequent association with other atopic conditions, and the less frequent intrinsic type (IAD), with normal IgE levels and no history of atopy. This retrospective study has the objective to compare the efficacy of dupilumab therapy in patients with IAD versus EAD in a real-life setting. We studied a group of 360 patients treated with dupilumab for moderate-to-severe AD of whom 49 had IAD (IgE < 200 kU/L and no history of other atopic conditions) and 311 had EAD (IgE ≥ 200 kU/L and/or history of atopy). There were no statistically significant differences in the achievement of EASI75 between IAD and EAD patients either at 16, 32, or 48 weeks (61% vs. 50%; 66% vs. 60%; and 53% vs. 65%, respectively). Similarly, there were no statistically significant differences in the achievement of EASI90 or the reduction in NRSpp, NRSsd, and DLQI at each timepoint. Additionally, mean absolute eosinophils and IgE values were significantly higher in the EAD group at all timepoints. This study confirms that dupilumab, targeting the Th2 pathway, which is known to be overexpressed in all AD phenotypes, appears to be equally effective in the two populations regardless of IgE levels.

Atopic march (AM) is the progression from atopic dermatitis (AD) to allergic rhinitis and asthma. The development of AD is as high as 20% in children worldwide and continues to increase. AD seems to be caused by both genetic and environmental factors. Recently, polymorphisms of the thymic stromal lymphopoietin (TSLP) gene associated with allergic disorders were reported in ethnic groups from various countries.

Atopic dermatitis (AD) is a chronic or chronically relapsing inflammatory skin disease which results from a complex, multifaceted interaction between environmental factors in genetically predisposed patients. Epidermal barrier impairment, alteration of the cutaneous microbiota, effect of external antigens, neurosensory dysfunction, and inflammatory and immune dysregulation all play a pivotal role in inducing and maintaining AD lesions. AD significantly impacts the patient's quality of life and general well-being and is often associated with anxiety and/or depressive symptoms. Classical treatment options include topical corticosteroids and calcineurin inhibitors, phototherapy, and systemic immunosuppression with oral corticosteroids, cyclosporine, methotrexate, and azathioprine in more severe cases. A turning point in facing AD was accomplished when the efficacy and safety of dupilumab, a monoclonal antibody targeting the interleukin (IL)-4 receptor α subunit, led to its approval for the treatment of moderate-to-severe or severe AD in children, adolescents, and adults. Subsequently, a more extensive understanding of AD etiology and pathogenesis has allowed the development of several topical and systemic novel therapy options. Most of these drugs are monoclonal antibodies which interfere with the type 2 inflammatory cascade, especially its key cytokines IL-4 and IL-13, or its downstream Janus kinase signaling pathway. However, considering the relevance of other subtypes of T helper (Th) cells, such as Th1 and Th22, and the important role of specific cytokines (IL-31) in generating pruritus, the horizon of potential therapeutic targets has widened extremely. In this review, we aim to present the most promising systemic agents currently under investigation and illustrate the most significant aspects of their efficacy, safety, and tolerability.

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.

Data from real-world use of new systemic treatments in atopic dermatitis (AD) is important for assessing safety and efficacy. The aim of this study is to describe the baseline characteristics of adult patients with moderate-to-severe AD enrolled in the Danish nationwide Severe and ChRonic Atopic dermatitis Treatment CoHort (SCRATCH) database, between October 2017 and August 2021. A total of 282 adult patients were included. Most (62%) were men, the median age at baseline was 43 years (interquartile range (IQR) 29-54 years), and median age at onset of AD was 1 year (IQR 0-6 years). The median Eczema Area and Severity Index at treatment initiation was 19.1 (IQR 11.9-25.7); median Patient Oriented Eczema Measure 21.0 (IQR 16.0-25.0); median Dermatology Life Quality Index 13.0 (IQR 7.0-19.0); and median itch and sleep numerical rating scale scores 8.0 (IQR 6.0-9.0) and 6.0 (IQR 4.0-8.0). Differences were found between the sexes. This registry will provide a source for future efficacy and safety studies.

Atopic dermatitis (AD) is a chronic and recurrent inflammatory skin disease, affecting up to 10% to 20% of children and 3% of adults. Although allergen sensitization, skin barrier abnormalities and type 2 immune responses are involved, the exact molecular pathogenesis of AD remains unclear. MicroRNAs (miRNAs) are short (19-25 nucleotides) single-stranded RNA molecules that regulate gene expression at post-transcriptional level and are implicated in the pathogenesis of many inflammatory and immunological skin disorders. This systematic review sought to summarize our current understanding regarding the role of miRNAs in AD development. We searched articles indexed in PubMed (MEDLINE) and Web of Science databases using Medical Subject Heading (MeSH) or Title/Abstract words ('microRNA/miRNA' and 'atopic dermatitis/eczema') from inception through January 2020. Observational studies revealed dysregulation of miRNAs, including miR-143, miR-146a, miR-151a, miR-155 and miR-223, in AD patients. Experimental studies confirmed their functions in regulating keratinocyte proliferation/apoptosis, cytokine signalling and nuclear factor-κB-dependent inflammatory responses, together with T helper 17 and regulatory T cell activities. Altogether, this systematic review brings together contemporary findings on how deregulation of miRNAs contributes to AD.

Atopic dermatitis is a heterogeneous, chronic, and inflammatory skin disease that is associated with a profound symptom burden. Recent studies have demonstrated associations between atopic dermatitis and a number of multi-organ and systemic disorders. The origin of these comorbid conditions is likely multifactorial, with combined effects of skin-barrier disruption, immune dysregulation, intense symptoms, and iatrogenic complications. Some of these comorbid conditions appear to be related to the underlying severity of atopic dermatitis and inadequate disease control. This review will summarize recent developments in the understanding of the comorbid health disorders associated with atopic dermatitis, particularly infections, sleep disturbances, and cardiovascular disease.

Atopic dermatitis (AD) is a chronic inflammatory disease. During the last years, researchers have focused on a variety of associated comorbidities, especially psychosocial disease. This article aims at giving an overview over recent data. A systematic literature research was performed in PubMed including data from the time period January 1, 2018 until March 1, 2020. Patients with AD frequently suffer from cocomitant depression, anxiety, and attention deficit hyperactivity disorder. There is less evidence about the relation between AD and schizophrenia, eating disorder, and obsessive compulsive disorder. There is still great need for research in the connection between AD and psychosocial disease, particularly about the pathogenesis and the influence of new therapies.

Atopic dermatitis (AD) is a chronic inflammatory disease caused by the complex interaction of genetic, immune and environmental factors. There have many recent discoveries involving the genetic and epigenetic studies of AD.

Atopic dermatitis (AD) is a common, chronic, relapsing, severely pruritic, eczematous skin disease. The mainstays of treatment for AD are topical tacrolimus and topical steroids. Tacrolimus, a calcineurin inhibitor, not only complements existing treatment options but also overcomes some of the drawbacks of topical steroid therapy when given topically and thus meets the long-term needs of patients in preventing disease progression. Topical tacrolimus has been widely recognized in terms of its short- and long-term efficacies and safety, and it is also accepted as a first-line treatment for inflammation in AD. The recent proactive use of topical tacrolimus may emphasize a long-term benefit of this calcineurin inhibitor for AD treatment. To reduce possible long-term adverse effects, it is important to monitor its topical doses in daily clinics.

Autism, a childhood behavioral disorder, belongs to a large suite of diseases, collectively referred to as autism spectrum disorders (ASD). Though multifactorial in etiology, approximately 10% of ASD are associated with atopic dermatitis (AD). Moreover, ASD prevalence increases further as AD severity worsens, though these disorders share no common causative mutations. We assessed here the link between these two disorders in the standard, valproic acid mouse model of ASD. In prior studies, there was no evidence of skin involvement, but we hypothesized that cutaneous involvement could be detected in experiments conducted in BALB/c mice. BALB/c is an albino, laboratory-bred strain of the house mouse and is among the most widely used inbred strains used in animal experimentation.

While numerous genetic loci associated with atopic dermatitis (AD) have been discovered, to date, work leveraging the combined burden of AD risk variants across the genome to predict disease risk has been limited.

Atopic dermatitis (AD) is a chronic, pruritic, inflammatory skin disease which predominately affects children and usually clears up during infancy or childhood. However, AD may persist with a chronic relapsing course until adulthood or develop at a later age. AD treatment can often be complicated. Treating moderate-to-severe AD can be challenging: only a few therapeutic options are available, with cyclosporine being the only approved and labeled systemic drug. In the last few years, advances in the knowledge of AD pathogenesis have been made that can provide the basis for developing new topical and systemic drugs. Among them, biologic drugs targeting specific cytokines involved in the development of the disease will probably revolutionize AD therapy. Currently, dupilumab, a monoclonal antibody that binds to the shared alpha chain subunit of the receptors for IL-4 and IL-13, is the only biologic drug licensed for the treatment of AD in adults. However, other biologic drugs that selectively target some key cytokines in AD pathogenesis (IL-13, IL-31, and IL-22) are also being studied. In this review, we discuss all of the biologic drugs that have been studied for AD treatment.

This study evaluated the anti-atopic dermatitis (AD) properties of Cordyceps militaris (CM) aqueous extract in keratinocytes in vitro and in vivo. We investigated the nutraceutical composition of the CM extract, including its protein, carbohydrate, and selected phytochemical content.

Childhood atopic dermatitis is a chronic inflammatory skin condition that causes significant psychological and financial costs to the individual and society. Treatment regimens may require long-term medication adherence and can be associated with poor patient satisfaction. There is considerable interest in complementary and integrative medicine (CIM) approaches for childhood atopic dermatitis.
