Abstract
BACKGROUND Severe atopic dermatitis (AD) is a complex disease requiring systemic treatment. This study aimed to assess the effectiveness of combined therapy consisting of dupilumab and sublingual dust mite allergen immunotherapy (SLIT-HDM) in patients with severe AD and HDM allergies. METHODS Patients diagnosed with severe AD were included in this randomised, placebo-controlled, double-blind 12-month trial; they received SLIT for HDMs and/or dupilumab for 12 months and were compared with patients on cyclosporine. The primary outcomes for the treatment arms were changes in the Eczema Area and Severity Index (EASI), body surface area (%BSA), and Investigator Global Assessment (IsGA) over 12 months. The secondary outcomes were the proportion of patients who achieved IsGA success and reduced medication scores. RESULTS Significant improvements were observed in all analysed groups after 12 months of therapy based on the EASI, %BSA, and IsGA. However, the most substantial changes were observed in the groups treated with dupilumab or a combination of SLIT-HDM and dupilumab. Additionally, the proportion of patients who achieved an IsGA reduction was significantly greater in the group receiving combination therapy than in the other groups (9/14 [64% of the group receiving SLIT-HDM] vs. 11/14 [73% of the group receiving dupilumab] vs. 15/17 [88% of the group receiving dupilumab and SLIT-HDM] vs. 7/13 [53% of the group receiving cyclosporine]) (p < 0.05). CONCLUSIONS In patients with severe AD and HDM allergies, combination treatment with dupilumab and allergen immunotherapy for HDMs may increase the therapeutic benefit over treatment with these methods separately.

Abstract
BACKGROUND Atopic dermatitis (eczema), can have a significant impact on well-being and quality of life for affected people and their families. Standard treatment is avoidance of triggers or irritants and regular application of emollients and topical steroids or calcineurin inhibitors. Thorough physical and psychological assessment is central to good-quality treatment. Overcoming barriers to provision of holistic treatment in dermatological practice is dependent on evaluation of the efficacy and economics of both psychological and educational interventions in this participant group. This review is based on a previous Cochrane review published in 2014, and now includes adults as well as children. OBJECTIVES To assess the clinical outcomes of educational and psychological interventions in children and adults with atopic dermatitis (eczema) and to summarise the availability and principal findings of relevant economic evaluations. SEARCH METHODS We searched the Cochrane Skin Specialised Register, CENTRAL, MEDLINE, Embase, APA PsycINFO and two trials registers up to March 2023. We checked the reference lists of included studies and related systematic reviews for further references to relevant randomised controlled trials (RCTs) and contacted experts in the field to identify additional studies. We searched NHS Economic Evaluation Database, MEDLINE and Embase for economic evaluations on 8 June 2022. SELECTION CRITERIA Randomised, cluster-randomised and cross-over RCTs that assess educational and psychological interventions for treating eczema in children and adults. DATA COLLECTION AND ANALYSIS We used standard Cochrane methods, with GRADE to assess the certainty of the evidence for each outcome. Primary outcomes were reduction in disease severity, as measured by clinical signs, patient-reported symptoms and improvement in health-related quality-of-life (HRQoL) measures. Secondary outcomes were improvement in long-term control of symptoms, improvement in psychological well-being, improvement in standard treatment concordance and adverse events. We assessed short- (up to 16 weeks after treatment) and long-term time points (more than 16 weeks). MAIN RESULTS We included 37 trials (6170 participants). Most trials were conducted in high-income countries (34/37), in outpatient settings (25/37). We judged three trials to be low risk of bias across all domains. Fifteen trials had a high risk of bias in at least one domain, mostly due to bias in measurement of the outcome. Trials assessed interventions compared to standard care. Individual educational interventions may reduce short-term clinical signs (measured by SCORing Atopic Dermatitis (SCORAD); mean difference (MD) -5.70, 95% confidence interval (CI) -9.39 to -2.01; 1 trial, 30 participants; low-certainty evidence) but patient-reported symptoms, HRQoL, long-term eczema control and psychological well-being were not reported. Group education interventions probably reduce clinical signs (SCORAD) both in the short term (MD -9.66, 95% CI -19.04 to -0.29; 3 studies, 731 participants; moderate-certainty evidence) and the long term (MD -7.22, 95% CI -11.01 to -3.43; 3 studies, 1424 participants; moderate-certainty evidence) and probably reduce long-term patient-reported symptoms (SMD -0.47 95% CI -0.60 to -0.33; 2 studies, 908 participants; moderate-certainty evidence). They may slightly improve short-term HRQoL (SMD -0.19, 95% CI -0.36 to -0.01; 4 studies, 746 participants; low-certainty evidence), but may make little or no difference to short-term psychological well-being (Perceived Stress Scale (PSS); MD -2.47, 95% CI -5.16 to 0.22; 1 study, 80 participants; low-certainty evidence). Long-term eczema control was not reported. We don't know whether technology-mediated educational interventions could improve short-term clinical signs (SCORAD; 1 study; 29 participants; very low-certainty evidence). They may have little or no effect on short-term patient-reported symptoms (Patient Oriented Eczema Measure (POEM); MD -0.76, 95% CI -1.84 to 0.33; 2 studies; 195 participants; low-certainty evidence) and probably have little or no effect on short-term HRQoL (MD 0, 95% CI -0.03 to 0.03; 2 studies, 430 participants; moderate-certainty evidence). Technology-mediated education interventions probably slightly improve long-term eczema control (Recap of atopic eczema (RECAP); MD -1.5, 95% CI -3.13 to 0.13; 1 study, 232 participants; moderate-certainty evidence), and may improve short-term psychological well-being (MD -1.78, 95% CI -2.13 to -1.43; 1 study, 24 participants; low-certainty evidence). Habit reversal treatment may reduce short-term clinical signs (SCORAD; MD -6.57, 95% CI -13.04 to -0.1; 1 study, 33 participants; low-certainty evidence) but we are uncertain about any effects on short-term HRQoL (Children's Dermatology Life Quality Index (CDLQI); 1 study, 30 participants; very low-certainty evidence). Patient-reported symptoms, long-term eczema control and psychological well-being were not reported. We are uncertain whether arousal reduction therapy interventions could improve short-term clinical signs (Eczema Area and Severity Index (EASI); 1 study, 24 participants; very low-certainty evidence) or patient-reported symptoms (visual analogue scale (VAS); 1 study, 18 participants; very low-certainty evidence). Arousal reduction therapy may improve short-term HRQoL (Dermatitis Family Impact (DFI); MD -2.1, 95% CI -4.41 to 0.21; 1 study, 91 participants; low-certainty evidence) and psychological well-being (PSS; MD -1.2, 95% CI -3.38 to 0.98; 1 study, 91 participants; low-certainty evidence). Long-term eczema control was not reported. No studies reported standard care compared with self-help psychological interventions, psychological therapies or printed education; or adverse events. We identified two health economic studies. One found that a 12-week, technology-mediated, educational-support programme may be cost neutral. The other found that a nurse practitioner group-education intervention may have lower costs than standard care provided by a dermatologist, with comparable effectiveness. AUTHORS' CONCLUSIONS In-person, individual education, as an adjunct to conventional topical therapy, may reduce short-term eczema signs compared to standard care, but there is no information on eczema symptoms, quality of life or long-term outcomes. Group education probably reduces eczema signs and symptoms in the long term and may also improve quality of life in the short term. Favourable effects were also reported for technology-mediated education, habit reversal treatment and arousal reduction therapy. All favourable effects are of uncertain clinical significance, since they may not exceed the minimal clinically important difference (MCID) for the outcome measures used (MCID 8.7 points for SCORAD, 3.4 points for POEM). We found no trials of self-help psychological interventions, psychological therapies or printed education. Future trials should include more diverse populations, address shared priorities, evaluate long-term outcomes and ensure patients are involved in trial design.

Abstract
Atopic dermatitis is a chronic inflammatory skin disease characterised by recurrent eczema-like lesions and severe pruritus, along with drying and decrustation of skin. Current research relates the pathogenesis of atopic dermatitis mainly to genetic susceptibility, abnormal skin barrier function, immune disorders, Staphylococcus aureus colonisation, microbiological dysfunction and vitamin D insufficiency. Epigenetic modifications are distinct genetic phenotypes resulting from environment-driven changes in chromosome functions in the absence of nuclear DNA sequence variation. Classic epigenetic events include DNA methylation, histone protein modifications and non-coding RNA regulation. Increasing evidence has indicated that epigenetic events are involved in the pathogenesis of atopic dermatitis by their effects on multiple signalling pathways which in turn influence the above factors. This review primarily analyses the function of epigenetic regulation in the pathogenesis of atopic dermatitis. In addition, it tries to make recommendations for personalised epigenetic treatment strategies for atopic dermatitis in the future.

MEDICINA (KAUNAS, LITHUANIA) 2022; 59:medicina59010015. [PMID: 36676639 PMCID: PMC9867076 DOI: 10.3390/medicina59010015] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 12/08/2022] [Accepted: 12/16/2022] [Indexed: 12/24/2022]
Abstract
Background and objectives: Allergen immunotherapy (AIT) is not a first-line therapy in atopic dermatitis (AD) and its effectiveness has been criticised. Objectives: The efficacy and safety of AIT in adult patients with AD and monosensitisation to house dust mites (HDMs) were investigated. Materials and Methods: A total of 37 patients were included in this double-blind, placebo-controlled study. Patients were eligible if they were diagnosed with AD; had moderate-to-severe AD according to the Eczema Area and Severity Index (EASI) with at least 7.1 points, the % BSA (body surface area) scale with at least 16 points, and the IsGA (investigator global assessment) scale with 3 points; had positive skin prick tests (SPTs); and were positive for the specific immunoglobulin E (sIgE) response to D. pteronyssinus and D. farinae extracts, as well as Der p 1 and Der f1. The patients received Purethal mites (20,000 AUeq/mL, HAL Allergy, Leiden, The Netherlands) with the extract allergens D. pteronyssinus and D. farinae (50/50%) or a placebo for 12 months. The primary outcomes included changes in EASI, % BSA, and IsGA due to SCIT between the start and after 12 months of therapy. Results: In the study group, significant improvement was observed in terms of the EASI score from 43 ± 8.2 to 21 ± 5.9 points, % BSA from 72 ± 18 to 28 ± 11 points, and IsGA from 4.5 ± 0.5 to 1.5 ± 0.5 points in comparison with the placebo after 1 year of AIT. Additionally, the proportion of patients who achieved success in the IsGA (IsGA < 2) was significantly better in comparison to the placebo with 13/20 (65%) vs. 4/14 (29%), respectively (p < 0.05). Conclusions: HDM-AIT effectively improved atopic dermatitis in patients that strictly qualified for desensitisation with a confirmed monovalent mite allergy.

Abstract
Background: The treatment of chronic refractory moderate-to-severe atopic dermatitis (AD) has traditionally relied on broad-spectrum systemic anti-inflammatory agents. With the introduction of biologics and Janus kinase inhibitors (Jakinib), the step management of moderate-to-severe AD is rapidly changing; however, guidelines have yet to provide formal recommendations for how to best incorporate these agents into the treatment plan. Objective: To summarize the updated evidence-based medical treatment for AD, including a proposed position for biologics and Jakinibs in the treatment algorithm. Methods: A literature search of several medical literature data bases for guidelines, position papers, systematic reviews, and clinical trials from 2012 to 2022 on the treatment of moderate-to-severe AD was conducted to prepare this narrative review. Results: Emollients and topical corticosteroids are the mainstay for treating acute flares and for maintaining chronic control. Second-line topical agents include calcineurin inhibitors, e.g., tacrolimus and pimecrolimus; crisaborole; and ruxolitinib. For acute flares, cyclosporine is preferred over systemic corticosteroids. For chronic treatment, phototherapy should be considered before systemic anti-inflammatory agents. Of the traditional anti-inflammatory agents, cyclosporine is the first-line choice, with methotrexate and azathioprine equal secondary choices. Although abrocitinib may have better efficacy then dupilumab based on indirect comparisons, abrocitinib requires closer monitoring for adverse events. Based on package labeling, Jakinibs, e.g., abrocitinib and upadacitinib, should be used only after failure with other systemic agents, including biologics (e.g., dupilumab and tralokinumab). Biologics and Jakinibs should be considered before the traditional systemic anti-inflammatory agents. Conclusion: Clinicians should consider a modified step management for AD as they await the development of national and international guideline recommendations for how best to position the biologics and Jakinibs into the AD treatment algorithm.

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

Allergen immunotherapy for asthma prevention: A systematic review and meta-analysis of randomized and non-randomized controlled studies. Allergy 2022; 77:1719-1735. [PMID: 35342949 DOI: 10.1111/all.15295] [Citation(s) in RCA: 29] [Impact Index Per Article: 14.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2022] [Revised: 03/03/2022] [Accepted: 03/08/2022] [Indexed: 12/29/2022]
Abstract
BACKGROUND Allergen immunotherapy (AIT) is a disease-modifying treatment for IgE-mediated diseases. Randomized controlled trials (RCTs) support AIT's potential role in asthma prevention but evidence from non-randomized studies of interventions (NRSI) and longitudinal observational studies has been poorly addressed. Therefore, we aimed to conduct a systematic review and meta-analysis to assess clinical data from all study types to evaluate quantitatively the preventive role of AIT in asthma onset. METHODS We search three databases. Studies were screened, selected and evaluated for quality using risk-of-bias (ROB) tools. Data were descriptively summarized and meta-analysed using random effects. We performed a sensitivity, influence and subgroup analyses. Publication bias and heterogeneity were assessed. RESULTS From the 4549 identified studies, 24 (12 RCTs and 12 NRSI) were included in the qualitative synthesis and 18 underwent meta-analysis. One study was at low ROB, seven had moderate ROB, and 15 were proven of high ROB. Random-effects analysis showed a significant decrease in the risk of developing asthma following AIT by 25% (RR, 95% CI: 0.75, 0.64-0.88). This effect was not significant in the sensitivity analysis. Publication bias raised concerns, together with the moderate heterogeneity between studies (I2 = 58%). Subgroup analysis showed a remarkable preventive effect of AIT in children (RR, 95% CI: 0.71, 0.53-0.96), when completing 3 years of therapy (RR, 95% CI: 0.64, 0.47-0.88), and in mono-sensitized patients (RR, 95% CI: 0.49, 0.39-0.61). CONCLUSIONS Our findings support a possible preventive effect of AIT in asthma onset and suggest an enhanced effect when administered in children, mono-sensitized, and for at least 3 years, independently of allergen type.

Abstract
Atopic dermatitis (AD) is a chronic relapsing disease which causes characteristic eczematous skin lesions. The most common symptoms of atopic dermatitis are persistent pruritus, xerosis, and skin lesions with a typical location and appearance that changes with the patient’s age. The prevalence of the disease in the pediatric population is estimated at 10% to 30%, while in adults it ranges from 1% to 3%. The number of people who suffer from AD is rising every year. The pathophysiology of the disease is complex and multifactorial. It involves elements of epidermal barrier dysfunction, alterations in cellular immune response, IgE hypersensitivity, and environmental factors. AD significantly reduces the quality of life of both patients and their families. Patients with AD are at higher risk for neuropsychiatric disorders such as depression, attention-deficit/hyperactivity disorder, and headaches. The decreased quality of life of AD patients and their families is associated with the discomfort of recurrent and chronic inflammatory skin lesions, persistent pruritus, and the inconvenience of long-term therapy. It also affects the psychological development of children, contributes to behavioral disorders (hyperactivity, hypersensitivity) and impacts many areas of family life such as sleep, leisure activities, and relationships between family members. The basic treatment of AD is avoidance of potential harmful factors, proper care in the treatment of exacerbations, topical corticosteroids, and calcineurin inhibitors in proactive therapy. In some patients who meet age criteria, phototherapy and cyclosporine should be considered. In individuals with severe AD who do not respond to topical treatment and who will not benefit from general therapy, dupilumab, a biologic drug, is the treatment of choice. Biologic treatment has an increasingly important place in the effective and modern therapy of AD. Currently, new biologic drugs are being researched, which may bring a therapeutic revolution in AD in the future. Allergen immunotherapy in patients with AD should be carefully evaluated on an individual basis, as proper selection of patients with documented IgE-dependent sensitization is important for the success of this therapy. Close collaboration with the patient and their caregivers, education, and psychological support as appropriate are integral to the treatment.

Abstract
Seit dem ersten Bericht über die Allergenimmuntherapie (AIT) durch Noon et al. vor 110 Jahren wurden zahlreiche klinische und grundlagenwissenschaftliche Studien durchgeführt, um die Effekte der einzigen kurativen Behandlung von Allergien zu untersuchen. Bei der atopischen Dermatitis (AD) findet sie jedoch nur selten Anwendung, obwohl es Evidenz dafür gibt, dass Aeroallergene zu Exazerbationen der Erkrankung beitragen können. Dieser Übersichtsbeitrag umfasst die aktuelle Studienlage, Metaanalysen und Leitlinienempfehlungen zur AIT bei AD-Patienten. Es zeigt sich eine große Heterogenität hinsichtlich Studiendesigns, Patientenkohorten, Allergenen, Applikationsformen und Endpunkten, wodurch die Vergleichbarkeit der Studien erschwert wird. Mehrere Untersuchungen zeigen eine positive Wirkung der AIT auf den Schweregrad der AD, was darauf hindeutet, dass zumindest eine Untergruppe von Patienten von der Behandlung profitieren kann. Weitere Entwicklungen auf dem Gebiet der AIT könnten dazu beitragen, dass die Therapie einen breiteren Einsatz bei AD-Patienten findet.

Abstract
BACKGROUND Sensitization to house dust mites (HDMs) is frequent in patients with atopic dermatitis. OBJECTIVE To investigate the efficacy of sublingual immunotherapy (SLIT) with Dermatophagoides pteronyssinus extract in patients with atopic dermatitis sensitized to HDM. METHODS In this randomized, double-blind, placebo-controlled trial, we enrolled 91 patients 3 years or older, with SCORing Atopic Dermatitis (SCORAD) score greater than or equal to 15 and positive skin test result and/or IgE to D pteronyssinus. Patients were stratified according to age (<12 and ≥12 years) to receive HDM SLIT or placebo for 18 months. Primary outcome was a greater than or equal to 15-point decrease in SCORAD score. Secondary outcomes were decreases in SCORAD and objective SCORAD, Eczema Area and Severity Index, visual analog scale for symptoms, and pruritus scale scores; Investigator's Global Assessment 0/1; and decrease greater than or equal to 4 points in Dermatology Life Quality Index. Background therapy was maintained. RESULTS A total of 66 patients completed the study (35 HDM SLIT, 31 placebo). After 18 months, 74.2% and 58% of patients in the HDM SLIT group and the placebo group, respectively, showed greater than or equal to 15-point decrease in SCORAD score (relative risk, 1.28; 95% CI, 0.89-1.83). Significant SCORAD score decreases from baseline of 55.6% and 34.5% in HDM SLIT and placebo groups (mean difference, 20.4; 95% CI, 3.89-37.3), significant objective SCORAD score decreases of 56.8% and 34.9% in HDM SLIT and placebo groups (mean difference, 21.3; 95% CI, 0.66-41.81), and more patients with Investigator's Global Assessment 0/1 in the HDM SLIT group as compared with the placebo group (14 of 35 vs 5 of 31; relative risk, 2.63; 95% CI, 1.09-6.39) were observed at 18 months. CONCLUSIONS Our results suggest that HDM SLIT may be effective in HDM-sensitized patients as an add-on treatment for atopic dermatitis.

Abstract
Allergic rhinitis (AR) is an IgE-mediated disease that is characterized by Th2 joint inflammation. Allergen-specific immunotherapy (AIT) is indicated for AR when symptoms remain uncontrolled despite medication and allergen avoidance. AIT is considered to have been effective if it alleviated allergic symptoms, decreased medication use, improved the quality of life even after treatment cessation, and prevented the progression of AR to asthma and the onset of new sensitization. AIT can be administered subcutaneously or sublingually, and novel routes are still being developed, such as intra-lymphatically and epicutaneously. AIT aims at inducing allergen tolerance through modification of innate and adaptive immunologic responses. The main mechanism of AIT is control of type 2 inflammatory cells through induction of various functional regulatory cells such as regulatory T cells (Tregs), follicular T cells (Tfr), B cells (Bregs), dendritic cells (DCregs), innate lymphoid cells (IL-10+ ILCs), and natural killer cells (NKregs). However, AIT has a number of disadvantages: the long treatment period required to achieve greater efficacy, high cost, systemic allergic reactions, and the absence of a biomarker for predicting treatment responders. Currently, adjunctive therapies, vaccine adjuvants, and novel vaccine technologies are being studied to overcome the problems associated with AIT. This review presents an updated overview of AIT, with a special focus on AR.

Abstract
Unlike other barrier epithelia of internal organs, the stratified squamous epithelium of the skin is always exposed to the external environment. However, the robust barrier structure and function of the skin are highly resistant against external insults so as to not easily allow foreign invasions. Upon sensing danger signals, the innate immunity system is promptly activated. This process is mediated by alarmins, which are released passively from damaged cells. Nuclear alarmins or stressorins are actively released from intact cells in response to various cellular stresses. Alarmins/stressorins are deeply involved in the disease processes of chronic skin disorders of an unknown cause, such as rosacea, psoriasis, and atopic dermatitis. Furthermore, alarmins/stressorins are also induced in the congenital skin disorders of ichthyosis and keratoderma due to defective keratinization. Studies on alarmin activation and its downstream pathways may help develop novel therapeutic agents for intractable skin disorders.

Abstract
T cells are key drivers of autoimmunity in numerous noncommunicable inflammatory skin diseases by directly harming host tissue or through helping B cells in producing autoantibodies. Technological advances have contributed to identifying autoantigens, the Holy Grail of autoimmunity, in many inflammatory disorders of the skin. Novel therapeutic approaches such as chimeric (auto)antibody receptor T cells are a milestone on the way to finding individualized, well-tolerated, targeted therapies. This review summarizes the current knowledge on pathogenesis, immune response pattern‒related ontology, diagnostic approaches, and treatment options of autoimmune skin diseases.

Abstract
Atopic dermatitis (AD) is a chronic remitting-relapsing inflammatory skin disorder. Due to the multifactorial pathogenesis, there are numerous therapeutic management approaches, mainly based on symptomatic treatments. In recent years, allergen immunotherapy (AIT) has been progressively advanced as targeted disease-modifying treatment of allergic disease. The most recent guideline from the American Academy of Dermatology concludes that data available do not support its use in AD. The Joint Task Force and The European Academy of Dermatology suggest that clinicians can consider AIT treatment in selected patients characterized by aeroallergen sensitization, prevalently HDM, severe AD, and clinical exacerbation after exposure to the causative allergen. Nevertheless, its role in AD is still under debate, especially in children.

Abstract
BACKGROUND While the efficacy of allergen-specific immunotherapy (ASIT) to treat canine atopic dermatitis has been well established, it remains unclear why not all dogs show the same response to treatment. The goal of the study was to determine the relationship between duration of ASIT and two measurements of success: disease severity and concomitant medication sparing effect. METHODS Data were retrospectively compiled for 145 dogs with atopic dermatitis treated with ASIT. As a measure of treatment compliance, cases were stratified into dogs treated for less than 12 months or for at least 12 months. Treatment efficacy, defined as a reduction in disease severity score (scale 0-10), was compared between both groups, and correlations between treatment success and several related factors were examined. RESULTS ASIT treatment duration was strongly correlated with treatment efficacy. Animals treated for less than 12 months showed lower efficacy rates (22 per cent) than those treated for at least 12 months (65 per cent). Further, in animals treated for at least 12 months, concomitant medications were reduced more (87 per cent) than in animals treated for less than 12 months (39 per cent). CONCLUSION A lack of owner compliance emerged as the main factor explaining the reduced effectiveness of ASIT. To improve treatment adherence, veterinarians and owners need to be better informed about ASIT mechanisms of action before starting treatment.

Abstract
Allergen Immunotherapy (AIT) was introduced in clinical practice on an empirical basis more than 100 years ago. Since the first attempts, AIT was administered subcutaneously. Indeed, other routes of administration were proposed and studied, in particular to improve the safety, but only the sublingual route (SLIT) achieved a credibility based on evidence and was then accepted as a viable "alternative" option to the subcutaneous route. SLIT was largely used in clinical trials and clinical practice in this last 30 years. Thus, a large amount of data is available, coming from either controlled trials and postmarketing surveillance studies. It is clear that SLIT is overall effective, but it is also clear that the efficacy is not "class-related," as derived from meta-analyses, but restricted to each specific product. The 30-year lasting use of SLIT allowed to clarify many clinical aspects, such as efficacy, safety, use in asthma, regimens of administration, and optimal doses. In parallel, the mechanisms of action of AIT were elucidated, and new indications were proposed (eg food allergy, atopic dermatitis). In addition, the introduction of molecular-based diagnosis, allowed to better refine the prescription of SLIT, based on specific sensitization profiles. The present article will describe the origin and evolution of SLIT for respiratory allergy, taking into account the clinical context that suggested this form of treatment, the recently developed aspects, the future perspectives and unmet needs, This is not, therefore, a systematic review, rather a narrative historical description of the past history, and a look forward to the future opportunities.

Abstract
Given the inadequate overall awareness of the main disease features and treatment modalities of pruritus in pediatric patients with atopic dermatitis, a multidisciplinary Italian expert group met with the major aim of increasing knowledge of the condition for improved diagnosis and better management among specialists involved in disease management. Herein, the overall features of the condition are reviewed, along with its etiopathogenesis and symptoms. Likewise, management options are summarized, emphasizing the need for a multidisciplinary approach, minimally composed of a management team that includes a pediatrician, dermatologist, psychologist, play assistant, and dedicated nurse. In addition to more traditional therapies such as emollients as highlighted by European guidelines, therapeutic patient education in a group or individually is highly encouraged as it helps patients and their parents to better understand the disease and provide practical guidance for dressing and bandaging. It can also aid in outlining coping strategies for itching and sleep disturbance. The utility of distraction techniques should also be stressed as such educational interventions involving the child and their parents can substantially improve the overall quality of life. All approaches should be tailored according to patient age and clinical features and requires individualized strategy to ensure good adherence by both children and their parents. Thus, a holistic approach embracing systemic, topical and psychological interventions is advocated in order to provide patients and their caregivers the best possible care.

Abstract
Atopic dermatitis (AD) was once thought to be a benign childhood disease that remitted with increasing age. However, recent studies have transformed the understanding of AD, particularly in adult patients. AD is common in adults and can lead to substantial disability by negatively affecting sleep, mental health, and quality of life. There seem to be different genetic, immunologic, and epidemiologic risk factors for AD in adults than in children. This article examines the pathophysiology, epidemiology, heterogeneous clinical presentation, burden, diagnosis, and treatment of adult AD.

Abstract
PURPOSE OF REVIEW In light of the recent advancements in atopic dermatitis treatment, this review aims to summarize the utility and efficacy of allergy immunotherapy in atopic dermatitis patients. We examine its mechanism, pathophysiology, cost-efficacy, and current guidelines for clinical practice. RECENT FINDINGS The literature supports the use of allergy immunotherapy in atopic conditions such as allergic rhinitis and asthma but insufficient evidence exists to suggest its efficacy in atopic dermatitis. The use of allergy immunotherapy has been shown to provide long-term cost savings in both the USA and the European Union in certain populations but differences in prescribing patterns and manufacturing make it difficult to study its impact on a larger, generalizable scale. Conflicting meta-analyses data and conclusions highlight the need for better, higher quality research to better understand allergy immunotherapy utility in atopic dermatitis.

Abstract
Atopic dermatitis (AD) is a prevalent inflammatory skin disease characterized by its chronic nature and relapse. Ample evidence suggests that non-coding RNAs play a major role in AD pathogenesis. However, the mechanism remains unknown, particularly in AD recurrence. Dynamic morphological and cytokine changes were measured throughout the whole course of an FITC-induced AD recurrence murine model. Microarray assay and integrative analysis were performed to comprehensively explore long non-coding RNA (lncRNA), messenger RNA (mRNA), and microRNA (miRNA) networks. Our results showed that an AD recurrence model was established. Overall, 5766 lncRNAs, 4025 mRNAs, and 202 miRNAs changed after elicitation, whereas, 419 lncRNAs, 349 mRNAs, and more notably, only 23 miRNAs, were dysregulated in the remission phase. Gene ontology (GO) and KEGG pathway enrichment analyses were used to investigate the potential functions of the dysregulated genes. The altered regulation of seven miRNAs and seven lncRNAs were validated in different stages of the model. The competing endogenous RNA (ceRNA) network inferred that lncRNA humanlincRNA0490+ could compete for miR-155-5p binding, through which it might affect Pkiα expression. Altogether, our findings have provided a novel perspective on the potential roles of non-coding RNAs in AD, and suggest that specific non-coding RNAs could be new therapeutic targets against AD recurrence.

Abstract
In human patients with seasonal allergic rhinoconjunctivitis sensitized to grass pollen, the first successful allergen immunotherapy (AIT) was reported in 1911. Today, immunotherapy is an accepted treatment for allergic asthma, allergic rhinitis and hypersensitivities to insect venom. AIT is also used for atopic dermatitis and recently for food allergy. Subcutaneous, epicutaneous, intralymphatic, oral and sublingual protocols of AIT exist. In animals, most data are available in dogs where subcutaneous AIT is an accepted treatment for atopic dermatitis. Initiating a regulatory response and a production of "blocking" IgG antibodies with AIT are similar mechanisms in human beings and dogs with allergic diseases. Although subcutaneous immunotherapy is used for atopic dermatitis in cats, data for its efficacy are sparse. There is some evidence for successful treatment of feline asthma with AIT. In horses, most studies evaluate the effect of AIT on insect hypersensitivity with conflicting results although promising pilot studies have demonstrated the prophylaxis of insect hypersensitivity with recombinant antigens of biting midges (Culicoides spp.). Optimizing AIT using allergoids, peptide immunotherapy, recombinant allergens and new adjuvants with the different administration types of allergen extracts will further improve compliance and efficacy of this proven treatment modality.

Abstract
Atopic dermatitis (AD) is the most common chronic inflammatory skin disease, with a lifetime prevalence of up to 20% and substantial effects on quality of life. AD is characterized by intense itch, recurrent eczematous lesions and a fluctuating course. AD has a strong heritability component and is closely related to and commonly co-occurs with other atopic diseases (such as asthma and allergic rhinitis). Several pathophysiological mechanisms contribute to AD aetiology and clinical manifestations. Impairment of epidermal barrier function, for example, owing to deficiency in the structural protein filaggrin, can promote inflammation and T cell infiltration. The immune response in AD is skewed towards T helper 2 cell-mediated pathways and can in turn favour epidermal barrier disruption. Other contributing factors to AD onset include dysbiosis of the skin microbiota (in particular overgrowth of Staphylococcus aureus), systemic immune responses (including immunoglobulin E (IgE)-mediated sensitization) and neuroinflammation, which is involved in itch. Current treatments for AD include topical moisturizers and anti-inflammatory agents (such as corticosteroids, calcineurin inhibitors and cAMP-specific 3',5'-cyclic phosphodiesterase 4 (PDE4) inhibitors), phototherapy and systemic immunosuppressants. Translational research has fostered the development of targeted small molecules and biologic therapies, especially for moderate-to-severe disease.

Abstract
PURPOSE OF REVIEW The aim of this article is to discuss how allergen-specific immunotherapy (AIT) can be improved through molecular approaches. We provide a summary of next-generation molecular AIT approaches and of their clinical evaluation. Furthermore, we discuss the potential of next generation molecular AIT forms for the treatment of severe manifestations of allergy and mention possible future molecular strategies for the secondary and primary prevention of allergy. RECENT FINDINGS AIT has important advantages over symptomatic forms of allergy treatment but its further development is limited by the quality of the therapeutic antigen preparations which are derived from natural allergen sources. The field of allergy diagnosis is currently undergoing a dramatic improvement through the use of molecular testing with defined, mainly recombinant allergens which allows high-resolution diagnosis. Several studies demonstrate that molecular testing in early childhood can predict the development of symptomatic allergy later on in life. Clinical studies indicate that molecular AIT approaches have the potential to improve therapy of allergic diseases and may be used as allergen-specific forms of secondary and eventually primary prevention for allergy.

Abstract
BACKGROUND Children with severe, persistent atopic eczema (AE) have limited treatment options, often requiring systemic immunosuppression. OBJECTIVE To evaluate the effect of the temperature-controlled laminar airflow (TLA) treatment in children/adolescents with severe AE. METHODS We recruited 15 children aged 2-16 years with long-standing, severe AE and sensitization to ≥1 perennial inhalant allergen. Run-in period of 6-10 weeks (3 visits) was followed by 12-month treatment with overnight TLA (Airsonett® , Sweden). The primary outcome was eczema severity (SCORAD-Index and Investigator Global Assessment-IGA). Secondary outcomes included child/family dermatology quality of life and family impact questionnaires (CDQLI, FDQLI, DFI), patient-oriented eczema measure (POEM), medication requirements and healthcare contacts. The study is registered as ISRCTN65865773. RESULTS There was a significant reduction in AE severity ascertained by SCORAD and IGA during the 12-month intervention period (P < .001). SCORAD was reduced from a median of 34.9 [interquartile range 28.75-45.15] at Baseline to 17.2 [12.95-32.3] at the final visit, and IGA improved significantly from 4 [3-4] to 2 [1-3]. We observed a significant improvement in FDQLI (16.0 [12.25-19.0] to 12 [8-18], P = .023) and DFI (P = .011), but not CDQLI or POEM. Compared to 6-month period prior to enrolment, there was a significant reduction at six months after the start of the intervention in potent topical corticosteroids (P = .033). The exploratory cluster analysis revealed two strongly divergent patterns of response, with 9 patients classified as responders, and 6 as non-responders. CONCLUSION AND CLINICAL RELEVANCE Addition of TLA device to standard pharmacological treatment may be an effective add-on to the management of difficult-to-control AE.

Abstract
Allergen immunotherapy (AIT) is an effective treatment strategy for allergic diseases and has been used for more than 100 years. In recent years, however, the expectations on concepts, conduct, statistical evaluation, and reporting have developed significantly. Products have undergone dose-response and confirmative studies in adults and children to provide evidence for the optimal dosage, safety, and efficacy of AIT vaccines using subcutaneous and sublingual delivery pathways in large patient cohorts, ensuring solid conclusions to be drawn from them for the advantage of patients and societies alike. Those standards should be followed today, and products answering to them should be preferred over others lacking optimization and proof of efficacy and safety. Molecular and cellular mechanisms of AIT include early mast cell and basophil desensitization effects, regulation of T- and B-cell responses, regulation of IgE and IgG4 production, and inhibition of responses from eosinophils, mast cells, and basophils in the affected tissues. There were many developments to improve vaccination strategies, demonstration of new molecules involved in molecular mechanisms, and demonstration of new biomarkers for AIT during the last few years. The combination of probiotics, vitamins, and biological agents with AIT is highlighting current advances. Development of allergoids and recombinant and hypoallergenic vaccines to skew the immune response from IgE to IgG4 and regulation of dendritic cell, mast cell, basophil, innate lymphoid cell, T-cell, and B-cell responses to allergens are also discussed in detail.

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.

Abstract
Atopic conditions (atopic dermatitis, rhinitis, and asthma) belong to the most common noncommunicable diseases and are driven by chronic inflammatory reactions. They have a strong impact on the quality of life and represent a substantial and growing socio-economic burden. Interestingly, there is an increasing interest in the development of new therapeutic options with a number of biologics and small molecules targeting potential key mechanisms in atopic conditions. However, besides the safety issue, most of the new active substances are still evaluated according to the traditional efficacy paradigm focusing on the success in treating exacerbations and flares. Instead, the future approaches in drug development and assessment should rather concentrate on the long-term control of these diseases and consider their potential as disease-modifying strategies in the era of precision medicine. To reach this goal, a number of unsolved issues have to be addressed and consensually accepted by the stakeholders in this field. Thus, a successful and rapid development of new treatments requests a paradigm shift and a new way of thinking in the mind of physicians, pharmaceutical industry, regulators, and HTAs. This seems mandatory in order to optimize drug development and to facilitate the accessibility of new therapies to the growing population of patients suffering from atopic conditions on a global level.
