- When does atopic dermatitis warrant systemic therapy? Recommendations from an expert panel of the International Eczema Council(2017) SIMPSON, Eric L.; BRUIN-WELLER, Marjolein; FLOHR, Carsten; ARDERN-JONES, Michael R.; BARBAROT, Sebastien; DELEURAN, Mette; BIEBER, Thomas; VESTERGAARD, Christian; BROWN, Sara J.; CORK, Michael J.; DRUCKER, Aaron M.; EICHENFIELD, Lawrence F.; FOELSTER-HOLST, Regina; GUTTMAN-YASSKY, Emma; NOSBAUM, Audrey; REYNOLDS, Nick J.; SILVERBERG, Jonathan I.; SCHMITT, Jochen; SEYGER, Marieke M. B.; SPULS, Phyllis I.; STALDER, Jean-Francois; SU, John C.; TAKAOKA, Roberto; TRAIDL-HOFFMANN, Claudia; THYSSEN, Jacob P.; SCHAFT, Jorien van der; WOLLENBERG, Andreas; IRVINE, Alan D.; PALLER, Amy S.Background: Although most patients with atopic dermatitis (AD) are effectively managed with topical medication, a significant minority require systemic therapy. Guidelines for decision making about advancement to systemic therapy are lacking. Objective: To guide those considering use of systemic therapy in AD and provide a framework for evaluation before making this therapeutic decision with the patient. Methods: A subgroup of the International Eczema Council determined aspects to consider before prescribing systemic therapy. Topics were assigned to expert reviewers who performed a topic-specific literature review, referred to guidelines when available, and provided interpretation and expert opinion. Results: We recommend a systematic and holistic approach to assess patients with severe signs and symptoms of AD and impact on quality of life before systemic therapy. Steps taken before commencing systemic therapy include considering alternate or concomitant diagnoses, avoiding trigger factors, optimizing topical therapy, ensuring adequate patient/caregiver education, treating coexistent infection, assessing the impact on quality of life, and considering phototherapy. Limitations: Our work is a consensus statement, not a systematic review. Conclusion: The decision to start systemic medication should include assessment of severity and quality of life while considering the individual's general health status, psychologic needs, and personal attitudes toward systemic therapies.

I.This article is a report of the fourth meeting of the Harmonising Outcome Measures for Eczema (HOME) initiative held in Malmo, Sweden on 23-24 April 2015 (HOME IV). The aim of the meeting was to achieve consensus over the preferred outcome instruments for measuring patient-reported symptoms and quality of life for the HOME core outcome set for atopic eczema (AE). Following presentations, which included data from systematic reviews, consensus discussions were held in a mixture of whole group and small group discussions. Small groups were allocated a priori to ensure representation of different stakeholders and countries. Decisions were voted on using electronic keypads. For the patient-reported symptoms, the group agreed by vote that itch, sleep loss, dryness, redness/inflamed skin and irritated skin were all considered essential aspects of AE symptoms. Many instruments for capturing patient-reported symptoms were discussed [ including the Patient-Oriented SCOring Atopic Dermatitis index, Patient-Oriented Eczema Measure (POEM), Self-Administered Eczema Area and Severity Index, Itch Severity Scale, Atopic Dermatitis Quickscore and the Nottingham Eczema Severity Score] and, by consensus, POEM was selected as the preferred instrument to measure patient-reported symptoms. Further work is needed to determine the reliability and measurement error of POEM. Further work is also required to establish the importance of pain/soreness and the importance of collecting information regarding the intensity of symptoms in addition to their frequency. Much of the discussion on quality of life concerned the Dermatology Life Quality Index and Quality of Life Index for Atopic Dermatitis; however, consensus on a preferred instrument for measuring this domain could not be reached. In summary, POEM is recommended as the HOME core outcome instrument for measuring AE symptoms.
- Topical corticosteroid phobia in atopic dermatitis: International feasibility study of the TOPICOP score(2017) STALDER, J. -F.; AUBERT, H.; ANTHOINE, E.; FUTAMURA, M.; MARCOUX, D.; MORREN, M. -A.; TRZECIAK, M.; SZALAI, Z.; VERES, K.; DELEURAN, M.; VESTERGAARD, C.; BORALEVI, F.; CHU, C. -Y.; RAEVE, L. De; SVENSSON, A.; FOELSTER-HOLST, R.; BUCHNER, M.; TAKAOKA, R.; AOKI, V.; CHERNYSHOV, P.; CHERNYSHOVA, L.; MURRELL, D. F.; ZHAO, C.; MCKINSTER, C. D.; KOBYLETZKY, L. Von; EICHENFIELD, L.; TOTRI, C.; LIO, P.; SENESCHAL, J.; MORET, L.; BARBAROT, S.BackgroundAdherence to topical corticosteroids (TCS) is essential for the effective treatment of atopic dermatitis but can be limited by concerns about their use. This study examined the feasibility of applying the validated TOPICOP score for assessing TCS phobia across different countries. MethodsThis was a prospective multicentre feasibility study conducted in 21 hospitals in 17 countries. Patients >3 months of age with atopic dermatitis or their parents or legal representatives completed a validated translation of the TOPICOP questionnaire in the country's native language. Respondents also completed questionnaires collecting opinions about the feasibility and acceptability of the TOPICOP questionnaire. ResultsA total of 1564 participants in 15 countries were included in the analysis. 81% of respondents considered the questions clear or very clear, and 79% reported that it took less than 5 minutes to complete. Each of the individual items in the TOPICOP questionnaire was considered to be not at all difficult to answer by 49% to 74% of participants. The mean global TOPICOP score was 44.7%20.5. Mean TOPICOP subscores were 37.0 +/- 22.8% for knowledge and beliefs, 54.7 +/- 27.8% for fears and 50.1 +/- 29.1% for behaviours. Global scores and subscores differed between countries, although the subscores did not always vary in parallel, suggesting different levels of TCS phobia and different drivers for each country. ConclusionsThe TOPICOP score can be feasibly applied across countries and may therefore be useful for obtaining qualitative and quantitative data from international studies and for adapting patient education and treatment.
- Position Statement on Atopic Dermatitis in Sub-Saharan Africa: current status and roadmap(2019) SCHMID-GRENDELMEIER, P.; TAKAOKA, R.; AHOGO, K. C.; BELACHEW, W. A.; BROWN, S. J.; CORREIA, J. C.; CORREIA, M.; DEGBOE, B.; DORIZY-VUONG, V.; FAYE, O.; FULLER, L. C.; GRANDO, K.; HSU, C.; KAYITENKORE, K.; LUNJANI, N.; LY, F.; MAHAMADOU, G.; MANUEL, R. C. F.; DIA, M. Kebe; MASENGA, E. J.; BASEKE, C. Muteba; OUEDRAOGO, A. N.; RABENJA, F. Rapelanoro; SU, J.; TECLESSOU, J. N.; TODD, G.; TAIEB, A.Background The first International Society of Atopic Dermatitis (ISAD) global meeting dedicated to atopic dermatitis (AD) in Sub-Saharan Africa (SSA) was held in Geneva, Switzerland in April 2019. A total of 30 participants were present at the meeting, including those from 17 SSA countries, representatives of the World Health Organization (WHO), the International Foundation for Dermatology (IFD) (a committee of the International League of Dermatological Societies, ILDS ), the Fondation pour la Dermatite Atopique, as well as specialists in telemedicine, artificial intelligence and therapeutic patient education (TPE). Results AD is one of the most prevalent chronic inflammatory skin diseases in SSA. Besides neglected tropical diseases (NTDs) with a dermatological presentation, AD requires closer attention from the WHO and national Departments of Health. Conclusions A roadmap has been defined with top priorities such as access to essential medicines and devices for AD care, in particular emollients, better education of primary healthcare workers for adequate triage (e.g. better educational materials for skin diseases in pigmented skin generally and AD in particular, especially targeted to Africa), involvement of traditional healers and to a certain extent also patient education, bearing in mind the barriers to effective healthcare faced in SSA countries such as travel distances to health facilities, limited resources and the lack of dermatological expertise. In addition, several initiatives concerning AD research in SSA were discussed and should be implemented in close collaboration with the WHO and assessed at follow-up meetings, in particular, at the next ISAD meeting in Seoul, South Korea and African Society of Dermatology and Venereology (ASDV) meeting in Nairobi, Kenya, both in 2020.
- Global Allergy Forum and 3rd Davos Declaration 2015: Atopic dermatitis/Eczema: challenges and opportunities toward precision medicine(2016) BIEBER, T.; AKDIS, C.; LAUENER, R.; TRAIDL-HOFFMANN, C.; SCHMID-GRENDELMEIER, P.; SCHAEPPI, G.; ALLAM, J. -P.; APFELBACHER, C.; AUGUSTIN, M.; BECK, L.; BIEDERMANN, T.; BRAUN-FAHRLANDER, C.; CHEW, F.

- Atopic dermatitis in adults: clinical and epidemiological considerations(2013) ORFALI, Raquel Leao; SHIMIZUA, Marta M.; TAKAOKA, Roberto; ZANIBONI, Mariana C.; ISHIZAKI, Aline S.; COSTA, Anderson A.; TIBA, Ana Paula L.; SATO, Maria Notomi; AOKI, ValeriaObjective: Atopic dermatitis (AD) is a chronic inflammatory disease causing intense pruritus, and with typical clinical features. There are few epidemiological studies concerning AD in adults, aswell as little information about its prognostic. The aim of this study was to evaluate the clinical and epidemiological course of adults with AD. Methods: 80 patients aged above 18 years (mean age = 29 years) were selected (30 males and 50 females) and interviewed about hospitalization, systemic corticoid usage, age of ADonset, and personal and/or familial history of atopy. Disease severity was evaluated through the Scoring Atopic Dermatitis (SCORAD) tool. Laboratory examination included IgE serum levels and eosinophil blood count. Results: 71 out of 80 patients referred association with respiratory symptoms (18 had asthma, 17 had rhinitis, and 36 had both conditions); nine out of 80 patients denied any respiratory disease. AD patients were divided in mild (n = 25), moderate (n = 30), and severe (n = 25); 56% had one or more hospitalizations due to AD. A positive association was found between IgE serum levels, eosinophil blood count, and disease severity. Conclusion: Adult AD represents a clinical challenge that needs to be better characterized, since it can be misdiagnosed and interferes with the patient's social and personal life. The association of skin and respiratory atopic disease is frequent, and laboratory parameters such as circulating IgE levels and eosinophil blood count may be helpful to assess disease severity.
- Atopic dermatitis: correlation between non-damaged skin barrier function and disease activity(2012) ADDOR, Flavia A. S.; TAKAOKA, Roberto; RIVITTI, Evandro A.; AOKI, ValeriaBackground Atopic dermatitis (AD) is a chronic dermatosis, predominant in childhood, characterized by pruritus and eczematous-type lesions with xerosis as the prominent clinical sign. Objectives To analyze the correlation between biophysical measurements of skin barrier function and other assessment criteria of clinical severity according to Rajka and Langelands criteria. Methods Biophysical measurements [transepidermal water loss (TEWL) and corneometry] were obtained from 120 patients with the diagnosis of AD. Serum levels of IgE were also evaluated. Results A significant correlation between corneometry, TEWL, and clinical severity of AD was found. Data showed an inverse correlation between corneometry, TEWL, and AD severity, and a significant difference (P < 0.001) between mean of corneometry and TEWL and AD severity (mild, moderate, and severe). As for IgE levels, corneometry had significant negative correlation, in contrast with TEWL, which showed a significant positive correlation (P < 0.001). Conclusion Biophysical measurements of skin barrier in non-lesional skin of AD may work as an evaluation factor for AD severity.
- Therapeutic Patient Education in Atopic Dermatitis: Worldwide Experiences(2013) STALDER, Jean-Francois; BERNIER, Claire; BALL, Alan; RAEVE, Linda De; GIELER, Uwe; DELEURAN, Mette; MARCOUX, Danielle; EICHENFIELD, Lawrence F.; LIO, Peter; LEWIS-JONES, Sue; GELMETTI, Carlo; TAKAOKA, Roberto; CHIAVERINI, Christine; MISERY, Laurent; BARBAROT, SebastienTherapeutic patient education (TPE) has proven effective in increasing treatment adherence and improving quality of life (QoL) for patients with numerous chronic diseases, especially atopic dermatitis (AD). This study was undertaken to identify worldwide TPE experiences in AD treatment. Experts from 23 hospitals, located in 11 countries, responded to a questionnaire on 10 major items. Patients in TPE programs were mainly children and adolescents with moderate to severe AD or markedly affected QoL. Individual and collective approaches were used. Depending on the center, the number of sessions varied from one to six (corresponding to 2 to 12hours of education), and 20 to 200 patients were followed each year. Each center's education team comprised multidisciplinary professionals (e.g., doctors, nurses, psychologists). Evaluations were based on clinical assessment, QoL, a satisfaction index, or some combination of the three. When funding was obtained, it came from regional health authorities (France), insurance companies (Germany), donations (United States), or pharmaceutical firms (Japan, Italy). The role of patient associations was always highlighted, but their involvement in the TPE process varied from one country to another. Despite the nonexhaustive approach, our findings demonstrate the increasing interest in TPE for managing individuals with AD. In spite of the cultural and financial differences between countries, there is a consensus among experts to integrate education into the treatment of eczema.
- Staphylococcal enterotoxin B induces specific IgG4 and IgE antibody serum levels in atopic dermatitis(2015) ORFALI, Raquel L.; SATO, Maria N.; SANTOS, Vanessa G.; TITZ, Tiago O.; BRITO, Cyro A.; DUARTE, Alberto J. S.; TAKAOKA, Roberto; AOKI, ValeriaBackgroundAtopic dermatitis (AD) is a chronic recurrent inflammatory disease, with prevalence of about 10-20% in children and 1-3% in adults. Staphylococcus aureus is present in 80-100% of skin from atopic patients and is related to worsening of the disease by the action of enterotoxins. The aim of this study was to evaluate the profile of anti-Staphylococcus aureus enterotoxin B (SEB) antibody isotypes and IgG subclass levels in adult AD. MethodsWe selected 38 patients with AD, diagnosed by Hanifin and Rajka's criteria, aged between 18 and 65, and 26 healthy controls (HC). The severity of the disease was established according to the Eczema Area and Severity Index and patients graded as mild (28%), moderate (58%), and severe (14%). Sera were assessed for IgG subclasses, IgA, IgM, and IgE against SEB by ELISA. ResultsElevated circulating IgE and IgG4 anti-SEB antibody levels associated with decreased IgA and IgM levels were detected in patients with AD, when compared to HC individuals. The severity of AD was related to low IgG1 and IgG3 levels and a high IgE antibody response to SEB. Interestingly, absence of IgG4 response to SEB was lower in patients with AD (2.63%), when compared to controls (34.6%), while a similar absence was detected for IgG1 and IgE antibodies (AD, 23.3 and 18.4% vs. HC, 38.5 and 19.2%). ConclusionOur findings evidenced a contributing role for IgG4 and IgE antibodies in AD pathogenesis, which are triggered by staphylococcal superantigens.
- Atopic dermatitis: A global health perspective(2024) FAYE, Ousmane; FLOHR, Carsten; KABASHIMA, Kenji; MA, Lin; PALLER, Amy S.; RAPELANORO, Fahafahantsoa Rabenja; STEINHOFF, Martin; SU, John C.; TAKAOKA, Roberto; WOLLENBERG, Andreas; YEW, Yik Weng; POSTIGO, Jose A. Ruiz; SCHMID-GRENDELMEIER, Peter; TAIEB, AlainThe International Society of AD (ISAD) organized a roundtable on global aspects of AD at the WCD 2023 in Singapore. According to the Global Burden of Disease (GBD) consortium, at least 171 million individuals were affected with AD in 2019, corresponding to 2.23% of the world population, with age-standardized prevalence and incidence rates that were relatively stable from 1990 to 2019. Based on the panel experience, most AD cases are mild-to-moderate. Without parallel data on disease prevalence and severity, the GBD data are difficult to interpret in many regions. This gap is particularly important in countries with limited medical infrastructure, but indirect evidence suggests a significant burden of AD in low-and-medium resource settings, especially urban areas. The Singapore roundtable was an opportunity to compare experiences in World Bank category 1 (Madagascar and Mali), 3 (Brazil, China) and 4 (Australia, Germany, Qatar, USA, Singapore, Japan) countries. The panel concluded that current AD guidelines are not adapted for low resource settings and a more pragmatic approach, as developed by WHO for skin NTDs, would be advisable for minimal access to moisturizers and topical corticosteroids. The panel also recommended prioritizing prevention studies, regardless of the level of existing resources. For disease long-term control in World Bank category 3 and most category 4 countries, the main problem is not access to drugs for most mild-to-moderate cases, but rather poor compliance due to insufficient time at visits. Collaboration with WHO, patient advocacy groups and industry may promote global change, improve capacity training and fight current inequalities. Finally, optimizing management of AD and its comorbidities needs more action at the primary care level, because reaching specialist care is merely aspirational in most settings. Primary care empowerment with store and forward telemedicine and algorithms based on augmented intelligence is a future goal.
