Humanistic and Economic Burden of Atopic Dermatitis for Adults and Adolescents in the Middle East and Africa Region

The hidden burden of atopic dermatitis in central and Eastern European countries

BACKGROUND

Atopic dermatitis (AD) imposes a hidden burden through its negative effects on quality of life and productivity. We aim to estimate this hidden burden in adults and adolescents in Central and Eastern European (CEE) countries.

METHODS

We created a burden of disease model to quantify AD's hidden burden. Humanistic burden was calculated by estimating the monetary value of quality-adjusted life years (QALYs) lost, using prevalence data from the Global Burden of Disease study and gross domestic product (GDP) per capita for each country. Indirect economic burden was estimated based on productivity loss from absenteeism and presenteeism, adjusted for labor force participation and unemployment rates. Total hidden burden was determined by combining productivity losses and QALYs lost.

RESULTS

QALY loss due to AD ranged from 1,832 to 58,596 annually in CEE countries, equating to 38 million to approximately 1 billion Euros per country. Productivity losses ranged from 3.6 to 148.9 million Euros annually. The total hidden burden of AD represents 0.11% to 0.43% of the GDP.

CONCLUSIONS

Our estimates reflect significant differences in population size, prevalence, and economic strength among CEE countries. Adjusting findings to country-specific GDP provided insights into AD's true hidden burden, offering valuable information for decision-making.

Effects of Water Bathing on Atopic Dermatitis Are Determined by the Constituents in the Water

Atopic dermatitis (AD) is a common skin disorder. Although a wide range of therapeutic regimens are available, they have some limitations, including high medical costs. However, evidence suggests that adjuvant regimens such as water bathing are inexpensive and effective approaches for the management of AD. Bathing with either tap water or seawater alone can improve AD symptoms and signs. Combination of water bathing with topic emollient or corticosteroids can synergically alleviate AD. The underlying mechanisms by which water bathing benefits AD include improvements in epidermal function, inhibition of mast cell and Langerhans cell function, reductions in serine protease expression and activity, inhibition of cytokine expression, and upregulation of expression levels of antioxidant enzymes, as well as antimicrobial peptides. In this review, we summarize the effects of water bathing on AD in both humans and murine models as well as the underlying mechanisms.

Navigating the evolving landscape of atopic dermatitis: Challenges and future opportunities: The 4th Davos declaration

The 4th Davos Declaration was developed during the Global Allergy Forum in Davos which aimed to elevate the care of patients with atopic dermatitis (AD) by uniting experts and stakeholders. The forum addressed the high prevalence of AD, with a strategic focus on advancing research, treatment, and management to meet the evolving challenges in the field. This multidisciplinary forum brought together top leaders from research, clinical practice, policy, and patient advocacy to discuss the critical aspects of AD, including neuroimmunology, environmental factors, comorbidities, and breakthroughs in prevention, diagnosis, and treatment. The discussions were geared towards fostering a collaborative approach to integrate these advancements into practical, patient-centric care. The forum underlined the mounting burden of AD, attributing it to significant environmental and lifestyle changes. It acknowledged the progress in understanding AD and in developing targeted therapies but recognized a gap in translating these innovations into clinical practice. Emphasis was placed on the need for enhanced awareness, education, and stakeholder engagement to address this gap effectively and to consider environmental and lifestyle factors in a comprehensive disease management strategy. The 4th Davos Declaration marks a significant milestone in the journey to improve care for people with AD. By promoting a holistic approach that combines research, education, and clinical application, the Forum sets a roadmap for stakeholders to collaborate to improve patient outcomes in AD, reflecting a commitment to adapt and respond to the dynamic challenges of AD in a changing world.

Strategic Approaches to Reducing the Burden of Atopic Dermatitis in the Middle East and Africa Region

OBJECTIVES

Atopic dermatitis (AD) creates a significant burden on patients and society. This study proposes a set of health policy interventions that can reduce the burden of AD in the Middle East and Africa.

METHODS

We conducted a scoping review to find relevant actions that have been implemented or recommended to decrease AD burden globally. An expert panel was conducted to discuss the review findings, then experts were surveyed to suggest the most efficient actions. Finally, survey results and recommendations were formulated into key actions to reduce the burden in the Middle East and Africa region.

RESULTS

Recommended actions were related to 5 domains; capacity building, guidelines, research, public awareness, and patient support and education. Several actions related to each domain can help reduce the burden. One of the most advocated recommendations was investing in patient education through trained healthcare professionals. Understanding the disease and learning how to control it is a key cornerstone to treatment optimization and reducing the burden. Multidisciplinary care, publishing defined therapeutic guidelines, and investing in research were the most recommended actions based on the experts' discussion and survey results.

CONCLUSIONS

Although the burden of AD is the highest among dermatological diseases, a well-grounded action plan has the potential to reduce the disease burden. Decision makers may develop a national AD action plan by selecting the most relevant items of this study based on their potential impact, feasibility, timeliness, and affordability.

Real-World Clinical, Psychosocial, and Economic Burden of Atopic Dermatitis: Results From the ESSENTIAL AD Multicountry Study

INTRODUCTION

Limited real-world evidence exists about the burden of atopic dermatitis (AD) in patients receiving systemic or non-systemic therapies in clinical practices. ESSENTIAL AD was an observational study that aimed to fill this information gap.

METHODS

ESSENTIAL AD enrolled (September 2021-June 2022) adult patients with physician-confirmed AD that was routinely managed with systemic and non-systemic treatment in a real-world setting from 15 countries in Eastern Europe, the Middle East, and Africa. Primary outcome variables were Eczema Area and Severity Index (EASI), SCORing Atopic Dermatitis (SCORAD), and Dermatology Life Quality Index (DLQI) assessed during one office visit.

RESULTS

A total of 799 enrolled patients fulfilled selection criteria and were included in the study. Patients mean (standard deviation [SD]) age was 36.3 (14.4) years, 457 (57.2%) were female, and the majority of patients were white (647 [81.0%]). Mean (SD) time since AD diagnosis was 17.6 (15.2) years (median 16.5; interquartile range [IQR] 3.3-26.8). The mean (SD) EASI, SCORAD, and DLQI total scores were 11.3 (11.3 [median 8.1; IQR 3.6-15.8]), 37.8 (17.9 [median 35.5; IQR 24.2-49.0]), and 10.6 (7.2 [median 10.0; IQR 5.0-15.0]), respectively. Patients receiving systemic treatment had significantly higher disease burden (mean [SD] EASI 13.3 [13.0]; median [IQR] 9.6 [3.9-17.9]) versus non-systemic treatment (mean [SD] 9.3 [8.7]; median [IQR] 6.8 [3.0-13.2]; P < 0.0001). Results were similar for SCORAD (39.9 [19.6] vs 35.6 [15.7]; median [IQR] 38.6 [24.7-53.1] vs 32.6 [23.9-44.6]; P = 0.0017), and DLQI total scores (11.4 [7.4] vs 9.9 [6.9]; median [IQR] 11.0 [5.0-16.0] vs 9.0 [5.0-14.0]; P = 0.0033, respectively).

CONCLUSION

Patients with AD continue to have substantial disease burden despite treatment with systemic therapy, suggesting that a need for effective disease management remains, including effective therapies that improve psychological outcomes and reduce economic burden of AD, in Eastern Europe, the Middle East, and Africa.

Maternal supplementation with Limosilactobacillus reuteri FN041 for preventing infants with atopic dermatitis: study protocol for a randomized controlled trial

Background

Atopic dermatitis (AD) has increased rapidly with rapid urbanization; however, the treatment options for AD are lacking because the commonly used therapies can only alleviate symptoms. Limosilactobacillus reuteri (L. reuteri), FN041 is a specific strain isolated from human breast milk, and its protective potential against AD has been confirmed. This study aims to assess the efficacy of maternal consumption of L. reuteri FN041 during late pregnancy and lactation in preventing infantile AD.

Methods

First, a randomized, double-blind, placebo-controlled intervention study will be conducted on 340 pregnant females with babies at high risk for AD. These subjects will be randomly divided into four groups of different doses of L. reuteri FN041 (1 × 109, 5 × 109, and 1 × 1010 CFU/d) along with a placebo. The safety and efficacy of maternal use of L. reuteri FN041 for preventing infantile AD will be analyzed, and the most efficient dosage of L. reuteri FN041 will be determined. Subsequently, a multicenter cohort study of 500 pregnant females with babies at high risk for AD will be conducted to promote the maternal application of L. reuteri FN041. These subjects will be administered L. reuteri FN041 at the optimal dose determined during the first stage of late pregnancy and lactation, and their babies will be analyzed for AD development. Recruitment was initiated in October 2022.

Discussion

The primary outcome is the cumulative incidence of AD at 24 months after maternal consumption of L. reuteri FN041 during late pregnancy and lactation, whereas the secondary outcome is the efficiency of L. reuteri FN041 transfer from the mother's gut to breast milk and then the infant's gut after oral supplementation. This study will demonstrate the efficacy of edible probiotics isolated from breast milk in preventing or treating AD in infants. Accordingly, we provide population-based advice for administering specific probiotics for the primary prevention of AD in pregnant females. Understanding the underlying mechanisms of probiotic strains derived from breast milk can promote their application in preventing infant diseases associated with intestinal microbiota imbalance and immune disorders.

Burden of Disease and Unmet Needs in the Diagnosis and Management of Atopic Dermatitis in the Arabic Population of the Middle East

Atopic dermatitis (AD) affects diverse ethnic groups with significant disparities in prevalence, disease progression, clinical outcomes, and access to care. There are limited data on AD in the Arabic population of the Middle East, yet there is a substantial economic and psychosocial burden of AD in this region with a large unmet need with regards to disease management that is critical to address. There is a trend of increasing prevalence of AD in the Arab Middle East; however, due to the large environmental, socioeconomic, and sociocultural heterogeneity of this region, prevalence varies greatly across and within countries. Similarly, clinical differences in disease presentations exist across the region, although data are limited. In this review, we will present clinical phenotypes of AD common in different regions of the Arab Middle East, and data on prevalence, genetic variations, and challenges of treatment. Further studies exploring molecular biomarkers, genetic polymorphisms, immune factors, and the microbiome of patients in the region will help to elucidate the mechanism behind ethnic differences in AD in this population as well as to understand susceptibilities and treatment response.
