The cost of childhood atopic dermatitis in a multi‐ethnic Asian population: a cost‐of‐illness study

Family management structural model for children with atopic dermatitis

PURPOSE

To construct a structural model of family management for children with atopic dermatitis.

DESIGN AND METHODS

In this cross-sectional study, data were collected using a structured questionnaire. Participants included primary caregivers of children aged 2-12 years who had received a medical diagnosis of atopic dermatitis and had been experiencing the condition for over three months. We used SPSS/WIN 26.0 to analyze the variables and AMOS 23.0 for structural equation modeling.

RESULTS

Family functioning resilience, social support, and family coping had significant direct effects on family management. Illness severity, illness duration, and family life difficulty indirectly influenced family management, demonstrating significant total effects. The severity and duration of atopic dermatitis, family life difficulty, family functioning resilience, social support, and family coping explained 78.9% of the model.

CONCLUSIONS

The final model was suitable for predicting family management for children with atopic dermatitis. By confirming mediating effects, this study contributes to enhancing family management through nursing interventions. These findings offer valuable insights for developing family-centered nursing strategies to improve family management for children with atopic dermatitis.

PRACTICE IMPLICATIONS

Nursing interventions targeting the alleviation of family management challenges and enhancement of family functioning resilience, social support, and family coping are pivotal for improving the well-being of children with atopic dermatitis. Furthermore, tailored intervention development must take into account not only the severity and illness duration of atopic dermatitis in children but also the characteristics of the family. Improving family nursing through such tailored interventions can help enhance children's health and quality of life.

Atopic dermatitis: A global health perspective

The 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.

Asian herbal medicine for atopic dermatitis: a systematic review

Asian herbal medicines have been known for decades, and some have been used to treat atopic dermatitis (AD). This chronic and persistent inflammatory skin condition causes severe morbidity and negatively impacts the quality of life. In numerous trials, traditional Chinese medicines have demonstrated clinical efficacy for AD. However, there is no well-documented summary of the wide variety of Asian herbal medicines used in treating AD. We aimed to systematically summarize the use of Asian herbal medicine in AD. An English-language literature search was performed in three electronic medical databases: PubMed, Cochrane Library, and EBSCOhost using keywords [("atopic dermatitis" OR "atopic eczema") AND ("traditional" OR "herbal")] and limited to references published between January 2015 and December 2022. The literature included newborns, infants, children, adolescents, and adults. The review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension to determine the main criteria. The content and inclusiveness of the search were filtered using relevant terms (MeSH/Emtree), keywords, titles, and abstracts. Thirteen articles (12 randomized clinical trial + 1 clinical trial) reported a variety of herbal medicine compounds to treat AD with various efficacy. Most studies reported significant improvement when comparing the herbal medicine with a placebo, but only 1 study reported substantial improvement of SCORAD compared to corticosteroids. Asian herbal medicines have been studied and may be used as an alternative treatment in treating AD with fewer adverse effects. However, its role did not change the position of standard treatment in treating atopic dermatitis.

Impact of Atopic Dermatitis on Quality of Life of Caregivers: A Systematic Review and Meta-Analysis

Abstracts: Background: Atopic dermatitis (AD) is a chronic dermatological condition that affects both patients and their caregivers. Aims: To summarize evidence on the impact of AD on the quality of life (QoL) of caregiver. Methods: Observational studies were searched for in Medline, Embase, Cochrane Library, SCOPUS, and CINAHL databases up till March 1, 2023. Results: Seventy studies with a total of 33,291 study participants were identified. The Dermatitis Family Index (DFI) questionnaire featured in 29 studies and was chosen for further meta-analysis. The pooled DFI for all studies was 9.35 (95% confidence interval [CI] 6.94-11.76). For individual components, the highest component scores were for 1.24 for expenditure (95% CI 0.80-1.69), followed by 1.14 for emotions (95% CI 0.77-1.50), as well as sleep 1.12 (95% CI 0.71-1.54) and exhaustion 1.12 (95% CI 0.76-1.48). Meta-analysis on the effect of patient QoL on family QoL was conducted on 15 studies, with a pooled Spearman's rank coefficient using Infants' Dermatitis Quality of Life Index (IDQoL) was 0.632 (95% CI 0.558-0.707), whereas that using Children's Dermatology Life Quality Index (CDLQI) was 0.624 (95% CI 0.507-0.741). For the 17 studies correlating AD severity with family QoL, a pooled Spearman's rank coefficient of 0.425 (95% CI 0.330-0.521) was obtained. Conclusions: AD is associated with significant negative impacts on caregiver QoL, particularly in family finance, caregiver burnout, and sleep impairment. This was consistently affected by AD severity and patient QoL in all studies examining this association.

Methods used to account for caregivers' sex and gender within studies examining the financial burden of caregivers of children and adolescents : Results from a scoping review

Background

Interest in the financial burden of informal caregivers has been growing. Unfortunately, it remains unclear which method(s) should be used when quantifying this burden.

Purpose

We conducted a scoping review aimed at identifying which methods have been used to conduct such work and quantified their performance. We were also interested in examining how sex and gender considerations were considered within selected studies.

Data Sources

Using a standardized approach, we identified studies published between 2012 and 2022 that aimed to document the financial burden of caregivers to child and adolescent patients. Our search strategy was applied to the MEDLINE, Embase, CINHAL, and Academic Search Premier databases.

Study Selection

Manuscript selection was performed by pairs of reviewers.

Data Extraction

Data extraction was performed by one reviewer with a second reviewer performing quality control. Results were reported using a narrative approach.

Data Synthesis

We identified 9801 unique citations, of which 200 were included in our review. Selected studies covered various disease area (eg, infection/parasitic diseases [n = 31, 16%]) and included quantitative (n = 180, 90%), qualitative (n = 4, 2%) and mixed study designs (n = 16, 8%). Most studies (n = 182, 91%) used questionnaires/surveys, either alone or in combination with other methods, to assess caregivers' financial burden. Less than half (n = 93, 47%) of studies reported on caregivers' sex and none reported on their gender.

Conclusion

We conducted an unrestricted review of published studies examining caregiver's financial burden which allowed us to identify general methodological trends observed in this literature. We believe this work may help improve future studies focusing on this important issue.

Economic and Humanistic Burden in Paediatric Patients with Atopic Dermatitis

Data concerning the economic and humanistic burden in patients with paediatric atopic dermatitis (AD) and their families are scarce. This retrospective study investigated these burdens in paediatric patients with AD using maintenance treatment with topical corticosteroids and/or conventional systemic immunosuppressants. Patient-reported outcomes regarding quality of life, AD severity, and parental work-related impairment were completed at inclusion. Data on healthcare resource utilization and medication prescription were collected retrospectively over the previous 12 months. Patients were categorized into mild, moderate or severe AD, based on Eczema Area and Severity Index score and medication use. Costs per patient per year per AD severity category were calculated. A total of 101 patients (median age 11.0 years (interquartile range 7.5-14.0), 47.5% men) were included, of whom 38 had mild AD, 37 moderate AD, and 26 severe AD. Mean ± standard deviation (SD) total costs patient per year for mild, moderate and severe AD were €1,812 ± €1,280, €2,680 ± €3,127, and €5,861 ±  €3,993, respectively. Highest total direct and indirect costs were found in patients with severe AD, mainly due to higher healthcare and medication costs. Highest humanistic burden was found in patients with moderate AD. For example, the median (interquartile range) Patient-Oriented Eczema Measure score was significantly higher in these patients compared with mild and severe AD (19.0 (15.0-24.0) vs 12.0 (8.8-15.0) and 17.0 (9.5-22.0), respectively). AD in paediatric patients incurs considerable direct and indirect costs, especially in patients with severe AD. The high humanistic burden in patients with moderate AD underlines the need for effective and safe new treatment options for children with AD.

ImmUniverse Consortium: Multi-omics integrative approach in personalized medicine for immune-mediated inflammatory diseases

Immune mediated inflammatory diseases (IMIDs) are a heterogeneous group of debilitating, multifactorial and unrelated conditions featured by a dysregulated immune response leading to destructive chronic inflammation. The immune dysregulation can affect various organ systems: gut (e.g., inflammatory bowel disease), joints (e.g., rheumatoid arthritis), skin (e.g., psoriasis, atopic dermatitis), resulting in significant morbidity, reduced quality of life, increased risk for comorbidities, and premature death. As there are no reliable disease progression and therapy response biomarkers currently available, it is very hard to predict how the disease will develop and which treatments will be effective in a given patient. In addition, a considerable proportion of patients do not respond sufficiently to the treatment. ImmUniverse is a large collaborative consortium of 27 partners funded by the Innovative Medicine Initiative (IMI), which is sponsored by the European Union (Horizon 2020) and in-kind contributions of participating pharmaceutical companies within the European Federation of Pharmaceutical Industries and Associations (EFPIA). ImmUniverse aims to advance our understanding of the molecular mechanisms underlying two immune-mediated diseases, ulcerative colitis (UC) and atopic dermatitis (AD), by pursuing an integrative multi-omics approach. As a consequence of the heterogeneity among IMIDs patients, a comprehensive, evidence-based identification of novel biomarkers is necessary to enable appropriate patient stratification that would account for the inter-individual differences in disease severity, drug efficacy, side effects or prognosis. This would guide clinicians in the management of patients and represent a major step towards personalized medicine. ImmUniverse will combine the existing and novel advanced technologies, including multi-omics, to characterize both the tissue microenvironment and blood. This comprehensive, systems biology-oriented approach will allow for identification and validation of tissue and circulating biomarker signatures as well as mechanistic principles, which will provide information about disease severity and future disease progression. This truly makes the ImmUniverse Consortium an unparalleled approach.

Management of Atopic Dermatitis: The Role of Tacrolimus

Atopic dermatitis (AD) is a long-lasting inflammatory dermatological condition characterized by itchy, eczematous, sparsely tiny blisters that hold a clear watery substance. Additionally, the diseased skin can suppurate, occasionally with weeping with thickening of the affected skin. This is considered one of the top skin disorders involving both children and adult populations globally. The principal therapeutic intervention for AD is long-standing topical glucocorticoids, which have been used for several decades. Corticosteroid therapy brings several adverse drug effects (ADRs), including irreversible skin atrophy. Tacrolimus belongs to the class of calcineurin inhibitors, which is a type of immunomodulator possessing promising efficacy in treating AD. Topical tacrolimus is an effective and safe non-corticosteroid substitute treatment for AD. We reviewed the available literature to compare and institute the safety, efficacy, and effectiveness of tacrolimus when equated to corticosteroid therapy in managing AD.

Healthcare utilization and costs of atopic dermatitis in Taiwan

BACKGROUND

Atopic dermatitis (AD) is a common chronic skin disease. Only relatively scant studies from Asian countries have attempted to quantify AD-associated healthcare utilization and costs by using population-based databases. This study aims to evaluate the AD-associated annual healthcare utilization and costs in Taiwan.

METHODS

A retrospective matched-cohort study was conducted by matching the AD cases with controls at a 1:4 (cases:controls) ratio, with the data for both the cases and controls being sourced from the 2017 National Health Insurance Research Database (NHIRD). The AD patients were stratified by disease severity based on their treatments. Differences in the regression-adjusted frequency of care and costs between the cases and controls were compared using t-tests by the severity level of AD.

RESULTS

The incremental frequency of outpatient visits per year increased with AD severity (9.60, 11.28, and 16.23 for mild, moderate, and severe cases, respectively). However, the frequency of inpatient care and emergency room visits per year showed no consistent pattern associated with disease severity. The incremental total costs per year were NT$9,511.64, NT$9,705.20, and NT$15,762.09 for mild, moderate, and severe cases, respectively, and the outpatient and drug costs accounted for 46.65%-54.82% and 17.01%-31.20% of the total costs, respectively.

CONCLUSION

AD was found to impose significant healthcare costs, with estimated total cost burdens of NT$3.61 billion in 2017, which is 0.314% of Taiwan's national health expenditure and 0.020% of Taiwan's gross domestic product.

Study on the Molecular Basis of Huanglian Jiedu Decoction Against Atopic Dermatitis Integrating Chemistry, Biochemistry, and Metabolomics Strategies

Atopic dermatitis (AD) is a common chronic relapsing skin inflammation, which severely affect the quality of life of patients. Inhibiting itching and enhancing immunity to mitigate scratching are key elements in the fight against AD. Huanglian Jiedu decoction (HLJDD) has multiple pharmacological effects in the treatment of AD. However, the effective ingredients and underlying molecular mechanisms have not yet been fully explored. Thus, this study integrates chemistry, biochemistry, and metabolomics strategies to evaluate the active substance basis of HLJDD against AD. First, HLJDD was split to five fractions (CPF, 40AEF, 90AEF, PEF and WEF) and 72 chemical components were identified. NSD (Non-similarity degree) among the different fractions showed significant chemical differences (>81%). Interleukin IL-13, IL-17A, IL-3, IL-31, IL-33, IL4, IL-5, TSLP, IgE, and histamine in the serum, and IL-4Rα, JAK1, and HRH4 levels in skin, participating in inhibiting itching and regulating immunity signaling, were found to be restored to varying degrees in AD treating with HLJDD and its fractions, especially 40AEF and CPF. Untargeted metabolomics analysis demonstrated that forty metabolites were differential metabolites in plasma between the HLJDD-treated group and the AD group, involving in histidine metabolism, arginine biosynthesis, pyrimidine metabolism, and so on. Further, targeted metabolomics analysis revealed that eleven differential metabolites, associating with physiological and biochemical indices, were significant improved in the HLJDD and its fractions groups. In conclusion, HLJDD exhibited anti-AD effects by inhibiting itching and enhancing immunity, which in turn regulating the levels of relative metabolites, and CPF and 40AEF were considered the most important components of HLJDD.

Azithromycin pretreatment exacerbates atopic dermatitis in trimellitic anhydride-induced model mice accompanied by correlated changes in the gut microbiota and serum cytokines

Atopic dermatitis (AD) is a common inflammatory skin disease. This study aims to investigate the effect of azithromycin (AZI) pretreatment, a common macrolide-type antibiotic, on the trimellitic anhydride (TMA) induced AD-like symptoms in mice. AZI (25 mg/kg, once daily, 5 days) was administered intragastrically before the 10-day TMA challenge. AD-like symptoms were assessed by ear thickening, scratching behavior, and pathological or immunofluorescence staining; Cytokines in the skin tissue and serum were measured by cytometric bead array; and the compositions of gut microbiota were assessed by 16S rRNA gene sequencing. AZI pretreatment accelerated the development of ear thickening and enhanced the severity of developed AD-like symptoms. AZI pretreatment promoted the infiltrations of neutrophil-like cells, T cells, and mast cells in ear skin. AZI pretreatment elevated the levels of IL-4, IL-6, and IL-17A in the ear skin of AD model mice, but it increased serum TNF-α and IL-6. AZI-pretreatment increased four gut bacterial genera (Bacteroides, Candidatus_Saccharibacteria_unclassified, Acetatifactor, Firmicutes_unclassified) but depleted three short-chain fatty acids producing gut bacterial genera (Alistipes, Clostridiales_unclassified, Butyricicoccus). AD-associated symptoms were positively associated with skin IL-4 and IL-17A, serum TNF-α, and IL-6, and Acetatifactor, but they negatively correlated to the three decreased gut bacterial genera (Alistipes, Clostridiales_unclassified, Butyricicoccus). Thus, our results demonstrate that AZI exposure deteriorates TMA-induced AD-like symptoms in mice, which is related to the imbalances of gut microbiota and skin/serum cytokines.

"His first word was 'cream'." The burden of treatment in pediatric atopic dermatitis-A mixed methods study

The burden of treatment (BOT) is the workload of health care experienced by patients with chronic conditions and consequences on well-being. This study aimed to assess the BOT of atopic dermatitis (AD) on children and caregivers using mixed methods. The quantitative component of this mixed methods study involved the Treatment Burden Questionnaire. The qualitative component involved interviews with parents of children with moderate-severe AD. The questionnaire was completed by 168 parents; 32.1% had mild AD, 39.9% had moderate AD, and 28% had severe AD. The average burden score was 3.5 (out of 10). Average burden scores were low in mild AD (1.0 out of 10) and were proportionally higher in moderate (3.9 out of 10) and severe (5.8 out of 10) AD (p < 0.001). Increased frequency of therapy had increased perceived burden. In moderate-severe AD, oral therapy was rated as less burdensome than topical therapies. Semi-structured interviews were conducted with 15 parents of children with moderate-severe AD. Thematic analysis grouped experiences into health care burden, treatment burden, and financial burden. Insights from health care burden analysis included "mixed messages," "treatment futility," and "expectant resolution." Insights from treatment burden included treatment routine, schooling impact, and "topical-sparing" with systemic treatment. Factors of financial burden included topical treatments, clothing, and health care visits. Moderate-severe AD is associated with high BOT, particularly related to topical therapies, which may be reduced by systemic treatment. All physicians treating children with AD should avoid potentially damaging communication regarding mixed messages, treatment futility, and expectant resolution.

Association between ambient temperature and atopic dermatitis in Lanzhou, China: a time series analysis

Many studies have explored the association between temperature and atopic dermatitis (AD); however, the results are inconsistent. We used a quasi-Poisson function fitted to a distributed lag nonlinear model (DLNM) to evaluate the association between daily average temperature and AD outpatient visits from January 1, 2013, to December 31, 2019, in Lanzhou, China. We found that the exposure-response association curve was inversely "s-shaped," low-temperature effects occurred at a lag of 11 days and then lasted for 10 days, and high-temperature effects occurred on the current day and then significantly decreased. Both low and high ambient temperatures can increase the risk of outpatient visits. Compared with median temperature (12.89°C), the cumulative relative risk (RR) of extreme high temperature and moderate-high temperature were 1.847 (95% confidence interval [CI]: 1.613, 2.114) and 1.447 (95% CI: 1.298, 1.614), respectively, at lag0-7 days, and the cumulative RRs of extremely low temperature and moderate-low temperature were 1.004 (95% CI: 0.904, 1.115) and 1.056 (95% CI: 0.925, 1.205), respectively, at lag0-21 days. Females were more sensitive to high temperatures than males, and high or low temperatures had significant effects on children ≤14 years of age. Graphical abstract.

The Pathology of Type 2 Inflammation-Associated Itch in Atopic Dermatitis

Accumulated evidence on type 2 inflammation-associated itch in atopic dermatitis has recently been reported. Crosstalk between the immune and nervous systems (neuroimmune interactions) is prominent in atopic dermatitis research, particularly regarding itch and inflammation. A comprehensive understanding of bidirectional neuroimmune interactions will provide insights into the pathogenesis of itch and its treatment. There is currently no agreed cure for itch in atopic dermatitis; however, increasing numbers of novel and targeted biologic agents have potential for its management and are in the advanced stages of clinical trials. In this review, we summarize and discuss advances in our understanding of type 2 inflammation-associated itch and implications for its management and treatment in patients with atopic dermatitis.

Lifelong Impact of Severe Atopic Dermatitis on Quality of Life: A Case Report

Severe, uncontrolled atopic dermatitis (AD) persisting from childhood to adulthood can have enduring quality of life (QoL) impacts on daily functioning, academics, career, family and social life, and mental health. In addition, AD has an impact on direct and indirect healthcare resource utilization. Several studies have attempted to quantify the quality of life and direct/indirect economic burden of AD. However, these estimates may not capture the more intangible disease-related burden and associated economic burden. This was a qualitative case report that aimed to investigate the full lifetime impact of severe, uncontrolled AD on all aspects of a single patient's life. This case report emphasizes the enormous cumulative lifetime impact of severe, uncontrolled AD and where the qualitative indirect impact may not be fully captured. After obtaining consent, a patient, diagnosed with severe AD since birth, was asked close- and open-ended questions about AD history, direct and indirect healthcare resource utilization, and impact of AD on work, home, family, social life, daily functioning, and mental health over the course of her lifetime. Our patient attributed her severe, uncontrolled AD since birth to causing poor sleep quality, depression, anxiety, and difficulty with social connections and to her choosing an alternative, less physically demanding career. Early effects on sleep and school performance, along with impact on social connections, likely contribute to weaker career opportunities and further social isolation with age.

The global burden of atopic dermatitis: lessons from the Global Burden of Disease Study 1990-2017

BACKGROUND

The Global Burden of Disease (GBD) Study provides an annually updated resource to study disease-related morbidity and mortality worldwide.

OBJECTIVES

Here we present the burden estimates for atopic dermatitis (AD), including data from inception of the GBD project in 1990 until 2017.

METHODS

Data on the burden of AD were obtained from the GBD Study.

RESULTS

Atopic dermatitis (AD) ranks 15th among all nonfatal diseases and has the highest disease burden among skin diseases as measured by disability-adjusted life-years (DALYs). Overall, the global DALY rate for AD in 1990 was 121 [95% uncertainty interval (UI) 65·4-201] and remained similar in 2017 at 123 (95% UI 66·8-205). The three countries with the highest DALY rates of AD were Sweden (327, 95% UI 178-547), the UK (284, 95% UI 155-478) and Iceland (277, 95% UI 149-465), whereas Uzbekistan (85·1, 95% UI 45·2-144), Armenia (85·1, 95% UI 45·8-143) and Tajikistan (85·1, 95% UI 46·1-143) ranked lowest.

CONCLUSIONS

The global prevalence rate of AD has remained stable from 1990 to 2017. However, the distribution of AD by age groups shows a bimodal curve with the highest peak in early childhood, decreasing in prevalence among young adults, and a second peak in middle-aged and older populations. We also found a moderate positive correlation between a country's gross domestic product and disease burden. GBD data confirm the substantial worldwide burden of AD, which has remained stable since 1990 but shows significant geographical variation. Lifestyle factors, partially linked to affluence, are likely important disease drivers. However, the GBD methodology needs to be developed further to incorporate environmental risk factors, such as ultraviolet exposure, to understand better the geographical and age-related variations in disease burden.

Atopic dermatitis

Atopic dermatitis is a common inflammatory skin disorder characterised by recurrent eczematous lesions and intense itch. The disorder affects people of all ages and ethnicities, has a substantial psychosocial impact on patients and relatives, and is the leading cause of the global burden from skin disease. Atopic dermatitis is associated with increased risk of multiple comorbidities, including food allergy, asthma, allergic rhinitis, and mental health disorders. The pathophysiology is complex and involves a strong genetic predisposition, epidermal dysfunction, and T-cell driven inflammation. Although type-2 mechanisms are dominant, there is increasing evidence that the disorder involves multiple immune pathways. Currently, there is no cure, but increasing numbers of innovative and targeted therapies hold promise for achieving disease control, including in patients with recalcitrant disease. We summarise and discuss advances in our understanding of the disease and their implications for prevention, management, and future research.
