Clin Exp Allergy 2023; 53:156-172. [PMID: 36653940 DOI: 10.1111/cea.14263] [Citation(s) in RCA: 14] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Revised: 11/05/2022] [Accepted: 11/23/2022] [Indexed: 01/20/2023]
Abstract
Atopic dermatitis (AD) is one of the most common, chronic inflammatory skin diseases with a significant physical, emotional and socioeconomic burden. In recent years the understanding of AD pathogenesis has expanded from the Th2-centred perspective, with the recognition of the involvement of other immune axes. In different AD endotypes, influenced by environment, genetics and race, transcriptomic profiles have identified differing contributions of multiple immune axes such as, Th17, Th22 and Th1. The enriched pathogenic model of AD has catalysed the development of numerous biologic therapies targeting a range of key molecules implicated in disease progression. Currently, dupilumab and tralokinumab, which both target the Th2 pathway, are the only approved biologic therapies for AD in the United States and Europe. New biologic therapies in development, however, target different Th2-pathway molecules along with cytokines in other immune axes, including Th17 and Th22, offering promise for varied treatments for this heterogeneous disease. As the biologic pipeline advances, the integration into clinical practice and approval of these experimental biologics may provide more effective, tailored therapeutic solutions and illuminate on the pathologic processes of AD across a broader, more diverse patient population.

Abstract
Ustekinumab (brand name Stelara®) is a human interleukin-12 and -23 antagonist and has been indicated for the treatments of moderate to severe plaque psoriasis, psoriatic arthritis, Crohn's disease and ulcerative colitis. This review aims to synthesize and interpret the literature evaluating the off-label uses of ustekinumab. We performed searches in PubMed and ClinicalTrials.gov for clinical trials, observational studies, case series, and case reports evaluating label uses of ustekinumab. Studies evaluated the efficacy of ustekinumab for the following conditions: other types of psoriasis (expect plaque psoriasis and psoriatic arthritis), pityriasis rubra pilaris, hidradenitis suppurativa, atopic dermatitis, pyoderma gangrenosum, et al. Based on the available literature, ustekinumab appears to be a potential treatment choice for many other diseases. However, more clinical trials data are needed to adequately assess the safety and efficacy of ustekinumab for the treatment of these conditions.

Abstract
INTRODUCTION Atopic dermatitis (AD) is a chronic inflammatory skin disorder associated with intense itch/pruritus and skin lesions. Several modalities of treatment including topical therapy, systemic agents, and biologics are available for the treatment of disease. Despite this, management poses challenge due to chronic nature and recurrent episodes in many patients. Biologics represent an important option of treatment for patients who do not respond to the traditional treatment. AREAS COVERED In this article, we focused on efficacy and safety of biologics in the treatment of atopic dermatitis. Other therapies are out of the scope of this review. Articles from PubMed and Google scholar and cross references of retrieved articles were used to write the narrative review. EXPERT OPINION Biologics play an important role in the treatment of atopic dermatitis. Every biologic has its own place in the treatment considering pharmacological profile, efficacy, and safety. Several biologics have been studied in the treatment of moderate-to-severe cases who failed to provide adequate response to traditional treatment. Dupilumab, is approved for the treatment of moderate-to-severe atopic dermatitis. Tralokinumab and nemolizumab have shown promising results in patients with atopic dermatitis.

Abstract
INTRODUCTION Atopic dermatitis (AD) is a very common chronic inflammatory skin disease. Ustekinumab is a human monoclonal antibody approved for psoriasis, that targets the p40 subunit shared by interleukin (IL)-12 and IL-23, cytokines which may also play a role in AD. Administration of ustekinumab in AD has been presented in anecdotal reports with conflicting results. Our aim was to evaluate the precise value of this biologic drug on AD in real-world setting. MATERIAL AND METHOD We sistematically reviewed published data and analyzed aggregated results involving AD treated with ustekinumab. The main outcome was clinical improvement reported by each record. We classified this in three categories: "complete response", "partial response" and "no response". A multivariant model was used to assess association between response to ustekinumab and the following potential predictive factors: gender, age (age < or >50), duration of AD, history of asthma, previous use of biologic drugs, number of previous systemic therapies, serum levels of IgE and duration of ustekinumab therapy. RESULTS Data on 23 patients from eight articles were analyzed. Complete AD remission was reported in 8 patients (34.8%), while abscense of response was observed also in 8 patients (34.8%). Partial response was reported in 7 patients (30.4%). No differences were observed with respect to age, gender, history of asthma, naïve patient, duration of AD or duration of ustekinumab therapy. CONCLUSION We conclude from available data the IL-12/23 pathway is likely not an atractive target for AD. More no convincing data exist arguing against consideration of ustekinumab in AD patients. Other effective treatments are available and should be prioritized with good safety profile. Limitations are yet low number of studies and patients.WHAT'S ALREADY KNOWN ABOUT THIS TOPIC?Administration of ustekinumab in AD (atopic dermatitis) has been presented in anecdotical reports with conflicting resultsWHAT DOES THIS STUDY ADD?This work presents the largest cohort of AD patients treated with ustekinumab in a real-world setting.Ustekinumab resulted in similar rates of complete, partial and negative responses.Our findings demonstrate the IL-12/23 pathway is not an atractive target in AD.More novel and effective treatments for AD are available and should be prioritized.The impact of anti IL-12/IL-23p40 therapy in AD is still unclarified due to limited controlled trials.

Abstract
In severe cases of atopic dermatitis (AD) systemic treatment is indicated. So far, cyclosporine and systemic glucocorticosteroids represented the only systemic treatment options approved for the indications of AD in Germany; however, from clinical practice there is increasing evidence for beneficial therapeutic effects in AD by other immunosuppressive or immunomodulatory substances, such as mycophenolate, methotrexate, alitretinoin and ustekinumab. Beyond this, ongoing research activities focus on a better understanding of genetic and immunological aspects of this chronic inflammatory skin disease. Regarding treatment with mycophenolate, genetic polymorphisms in AD patients could be identified that might predict responsiveness to this medication. Moreover, several new substances specifically targeting inflammation in AD are currently being studied and the first promising treatment effects on skin condition and pruritic symptoms of AD could be observed. As an exceptional result of this development in September 2017 in Europe and therefore in Germany the first biologic as first-line treatment was approved for the indication of moderate to severe AD in adults. Dupilumab is a human monoclonal IgG4 antibody that blocks a subunit of the interleukin (IL)-4 and IL-13 receptors, thus inhibiting the proinflammatory effects of these cytokines. Furthermore, the cytokine IL-13 itself, the IL-31 receptor, which is of particular relevance for pruritus in AD, the histamine-4-receptor and Janus kinases represent further promising targets currently being investigated in clinical trials for the treatment of AD.

Abstract
Dendritic cells (DCs) are the professional antigen-presenting cells that recognize and present antigens to naïve T cells to induce antigen-specific adaptive immunity. Among the T-cell subsets, T helper type 2 (Th2) cells produce the humoral immune responses required for protection against helminthic disease by activating B cells. DCs induce a Th2 immune response at a certain immune environment. Basophil, eosinophil, mast cells, and type 2 innate lymphoid cells also induce Th2 immunity. However, in the case of DCs, controversy remains regarding which subsets of DCs induce Th2 immunity, which genes in DCs are directly or indirectly involved in inducing Th2 immunity, and the detailed mechanisms underlying induction, regulation, or maintenance of the DC-mediated Th2 immunity against allergic environments and parasite infection. A recent study has shown that a genetic defect in DCs causes an enhanced Th2 immunity leading to severe atopic dermatitis. We summarize the Th2 immune-inducing DC subsets, the genetic and environmental factors involved in DC-mediated Th2 immunity, and current therapeutic approaches for Th2-mediated immune disorders. This review is to provide an improved understanding of DC-mediated Th2 immunity and Th1/Th2 immune balancing, leading to control over their adverse consequences.

Abstract
Severe atopic dermatitis, which affects both adults and children, is a debilitating disorder with a significant decline of patients' quality of life. Although aetiopathogenic factors are currently a topic of study and interpretation, the main features of atopic eczema are skin barrier disturbance and immune dysregulation. Severe refractory disease that fails to improve with conventional therapy may benefit from biologic therapy. Progress in understanding immunopathology of atopic dermatitis have allowed identification of therapeutic molecular targets in the field of biological therapy. We reviewed the different biological treatments with a focus on novel targeted agents: Systemic immunotherapy (Omalizumab, Dupilumab, Lebrikizumab, Tralokinumab, Nemolizumab, Ustekinumab, Fezakinumab, Tezepelumab, Apremilast, allergen specific immunotherapy), and topical agents (Tofacitinib, Crisaborole).

Abstract
INTRODUCTION Treatment guidelines endorse a variety of strategies for atopic dermatitis (AD) which may vary from published data and clinical practice patterns. The objective of this review was to quantify the volume of available medical literature supporting pediatric AD treatments and compare these patterns to those recommended by published guidelines and/or clinical practice patterns. METHODS Searches of Embase (2005-2016) and abstracts from selected meetings (2014-2016) related to AD treatment in patients younger than 17 years of age yielded references that were assessed by study design, primary treatment, age groups, and AD severity. RESULTS Published literature partially supports clinical guidelines, with emollients and topical medications being the most investigated. There were disproportionately more publications for topical calcineurin inhibitors (TCI) compared with topical corticosteroids (TCS); however, the search interval may have biased the results toward treatments approved near the beginning of the time frame. In contrast, publications documenting clinical practice patterns reflect greater use of emollients and TCS (over TCI), as well as systemic corticosteroids. Data is relatively limited for long-term and combination treatment, treatment of severe AD, and patients younger than 2 years of age, and completely lacking for systemic corticosteroids. CONCLUSION This scoping review demonstrates that available medical literature largely supports published guidelines for topical therapy; however, clinical practice patterns are less aligned. There is a lack of data for older, more frequently used generic treatments, including oral antihistamines, oral antibiotics, and systemic corticosteroids. Overall, literature is lacking for long-term treatment, treatment for patients younger than 2 years of age, and for systemic treatment for severe disease. FUNDING Regeneron Pharmaceuticals Inc.

Abstract
Atopic dermatitis (AD) is one of the most common inflammatory skin diseases. The number of people affected by AD is relatively high and seems to be rising. Although mild and moderate forms of the disease can be well controlled by the use of emollients, topical corticosteroids, and topical calcineurin inhibitors, treatment of severe is still a huge challenge. The new hope is biologic drugs, magic bullets in allergy, targeted at different points of the complex pathomechanism of inflammation in AD. In this review, novel biologic therapies are discussed, including recombinant monoclonal antibodies directed against various interleukin pathways (such as IL-4, IL-13, TSLP, IL-31, and IL-12/23), on immunoglobulin E, molecules acting as T cells, B cells, etc. Of biological drugs, the most promising seems to be anti-IL-4/IL-13 therapy (dupilumab-the biological agent) and phosphodiesterase-4 inhibitor (crisaborole-a small molecule). A deep understanding of the AD pathomechanism provides a new perspective for tailor-made treatment of severe atopic dermatitis.

Abstract
Atopic dermatitis (AD) is the most common inflammatory skin disease, but treatment options for moderate-to-severe disease are limited. Ustekinumab is an IL-12/IL-23p40 antagonist that suppresses Th1, Th17 and Th22 activation, commonly used for psoriasis patients. We sought to assess efficacy and safety of ustekinumab in patients with moderate-to-severe AD. In this phase II, double-blind, placebo-controlled study, 33 patients with moderate-to-severe AD were randomly assigned to either ustekinumab (n=16) or placebo (n=17), with subsequent crossover at 16 weeks, and last dose at 32 weeks. Background therapy with mild topical steroids was allowed to promote retention. Study endpoints included clinical (SCORAD50) and biopsy-based measures of tissue structure and inflammation, using protein and gene expression studies. The ustekinumab group achieved higher SCORAD50 responses at 12, 16 (the primary endpoint) and 20 weeks compared to placebo, but the difference between groups was not significant. The AD molecular profile/transcriptome showed early robust gene modulation, with sustained further improvements until 32 weeks in the initial ustekinumab group. Distinct and more robust modulation of Th1, Th17 and Th22 but also Th2-related AD genes was seen after 4 weeks of ustekinumab treatment (i.e. MMP12, IL-22, IL-13, IFN-γ, elafin/PI3, CXCL1 and CCL17; P<.05). Epidermal responses (K16, terminal differentiation) showed faster (4 weeks) and long-term regulation (32 weeks) from baseline in the ustekinumab group. No severe adverse events were observed. Ustekinumab had clear clinical and molecular effects, but clinical outcomes might have been obscured by a profound "placebo" effect, most likely due to background topical glucocorticosteroids and possibly insufficient dosing for AD.

Abstract
The pathogenesis of atopic dermatitis (AD) is multifactorial and complex. Consequently, clinical signs and symptoms vary strongly depending on individually relevant trigger factors and the stage of the disease. So far, treatment of AD was commonly limited to topical treatment or, in more severe cases, to systemic drugs mostly approved for other indications than AD. However, emerging data on new anti-inflammatory agents have been published in the recent years. As these new substances specifically focus on immune responses in AD, these are partially considered as possible 'breakthrough' in the treatment of AD. Therapeutic strategies of the future appear to be 'customized' for inflammation in AD as they target pro-inflammatory, highly relevant cytokines and cytokine receptors, such as IL-4Rα, IL-13, IL-31, and IL-17. Further innovative therapeutic approaches aim to block the function of relevant molecules such as thymic stromal lymphopoietin, chemoattractant-receptor homologous molecule expressed on Th2 lymphocytes (CRTh2), and phosphodiesterase (PDE)-4 inhibitors. Recently, anti-inflammatory effects in AD by antagonizing the histamine (H)-4 receptor have also been detected. Finally, specific immunotherapy is under further investigation as treatment option for AD patients with clinically relevant sensitization.
