Economic Impact of Atopic Dermatitis in Adults: A Population-Based Study (IDEA Study)

Humanistic and Economic Burden of Atopic Dermatitis in Pediatric Patients in Spain: A Systematic Review

Atopic dermatitis (AD) is a chronic, inflammatory skin disease affecting all age groups, particularly children. This systematic review provides an overview of the humanistic and economic disease burden in the pediatric population with AD in Spain. The evidence, collected from 11 observational studies published over the past 10 years, exhibits the most common characteristics of the patients, disease burden, patient-reported outcomes, use of resources, and treatment patterns. The burden of AD extends beyond physical symptoms, with associated comorbidities such as asthma and impaired health-related quality of life and mental health disorders, particularly in severe cases. Traditional therapies, primarily topical corticosteroids, face adherence and efficacy challenges. Despite promising innovative treatments and available biological therapies, their use is still limited in the pediatric population. The findings of the present review highlight the scarce scientific evidence on the economic burden of pediatric AD, as well as the most updated humanistic evidence on this disease. At the same time, the need for individualized care and innovative therapeutic interventions to address the multifaceted challenges of pediatric AD in Spain is evident.

Economic burden of atopic dermatitis in Portugal: a cross-sectional study

Atopic dermatitis (AD) is a chronic inflammatory skin condition that significantly impacts patients' quality of life and imposes substantial economic burdens due to direct medical costs and indirect costs such as absenteeism and loss of productivity. This study aimed to quantify the economic impact of AD in Portugal. A cross-sectional study was conducted on AD-diagnosed Portuguese residents using a 70-question survey, distributed between June 2019 and January 2020, including DLQI, EQ-5D, and VAS scales, to assess AD's 12 months impact. Statistical analysis included univariate and bivariate methods with post-stratification by disease severity. Findings revealed a mean DLQI score of 9.4 and a 24% productivity loss equating to 50 workdays annually. The economic impact calculated from the participation in the labor market totaled €1.477 million, including €43 million from absenteeism, €1.295 million from presenteeism, and €139 million of missed days by family members. The economic value of time spent treating the disease amounts to €311 million. The total annual cost of treating the disease is shared between the NHS (€218 million) and the patient out-of-pocket cost (€800 million). These results highlight AD's significant economic burden in Portugal, underscoring the need for comprehensive strategies to improve disease management, access to dermatological care, and quality of life. This study emphasizes the importance of investing in AD health services and promoting access to effective treatments to achieve economic and societal benefits.

The economic burden of atopic dermatitis in Romania: a broad perspective

Introduction

Atopic dermatitis (AD), a common dermatological condition, is often associated with significant economic and social burdens. Despite extensive studies globally, there is a gap in understanding the impact of this condition in Romania. This study evaluated the economic burden of AD in Romania, considering both direct and indirect costs.

Materials and methods

A cost of illness study, conducted from a broad perspective, considering 2022 as a reference, using top-down and bottom-up approaches and retrospective and prospective data sources was used to assess direct medical costs (treatments, medical services, hospitalizations), direct non-medical costs (associated costs due to transportation, accommodation), and indirect costs (productivity losses) across four costing scenarios.

Results

In 2022, the total cost of atopic dermatitis in Romania was €29,810,077.2 for adult patients and €133,635,535.2 for pediatric patients, based on a prevalence-based approach, and €5,529,867.8 for adults and €53,175,049.1 for pediatric AD patients when using an incidence-based approach. Medical costs had the highest attributable share of the AD cost for adult patients while productivity costs (inquired by caregivers) had the highest share for pediatric AD patients in both approaches. The overall average annual cost per patient ranged, depending on the scenarios, between €284.72 and €1,045 for adult AD patients and between €293.73 and €9,558.52 for pediatric AD patients.

Discussion

Our results show the increased burden among pediatric AD patients emphasizing the need that future policy interventions should be tailored according the patients' age.

Cost-Effectiveness Analysis of Abrocitinib Compared with Other Systemic Treatments for Severe Atopic Dermatitis in Spain

INTRODUCTION

Atopic dermatitis (AD) is a chronic, inflammatory skin disease characterized by itchy, painful, and dry skin. Despite the great number of available therapies, economic evaluations are still needed to provide evidence on their cost efficiency. This research aimed to evaluate the cost effectiveness of the Janus kinase (JAK) inhibitor abrocitinib (200 mg) compared with dupilumab (300 mg), tralokinumab (300 mg), baricitinib (2 and 4 mg), and upadacitinib (15 and 30 mg) for the treatment of patients with severe AD from the Spanish National Health System (NHS) perspective.

METHODS

A hybrid model consisting of a decision tree linked to a Markov model was developed to estimate costs, quality-adjusted life-years (QALYs), total years in response and incremental cost-per-QALY gained (willingness-to-pay [WTP] threshold: €25,000/QALY). Adults with severe AD entered the decision tree and response (75% reduction in baseline Eczema Area and Severity Index score, EASI-75) was considered at 16 and 52 weeks. After this time, patients entered the Markov model (remainder of the 10-year time horizon), which consisted of three health states: maintenance with active therapy, subsequent treatment, or death. All costs were presented in 2022 euros (€). Additionally, cost per number-needed-to-treat (NNT) was calculated for abrocitinib and dupilumab based on a head-to-head post-hoc analysis.

RESULTS

Abrocitinib 200 mg was dominant (i.e., lower incremental costs and higher incremental benefit) compared with all studied alternatives (dupilumab 300 mg, tralokinumab 300 mg, baricitinib 2 and 4 mg, upadacitinib 15 and 30 mg) with a QALYs gain of 0.49, 0.60, 0.64, 0.43, 0.45, and 0.08, respectively, and per-person costs savings of €22,097, €24,140, €14,825, €7,116, €12,805, and €45,189, respectively. Considering the WTP threshold, abrocitinib was dominant or cost effective compared with all alternatives for most simulations. Additionally, abrocitinib was dominant compared with all alternatives when evaluating the cost effectiveness over a 5-year time horizon. NNT showed that abrocitinib was dominant versus dupilumab.

CONCLUSIONS

The results of the study show that abrocitinib is a cost-effective therapy compared with other JAK inhibitors and biological therapies from the Spanish NHS perspective.

Improvement in Cutaneous Conditions Can Benefit Some Health Conditions in the Elderly

As we are aging, a number of cutaneous and extracutaneous disorders will be developed. Although the pathogenesis of these aging-associated disorders is not clear yet, abnormalities in the skin are linked to some aging-associated disorders at least to some extent. Inflammatory dermatoses such as psoriasis and atopic dermatitis predispose to the development of cardiovascular diseases, obesity and type 2 diabetes. In addition, both chronologically aged skin and individuals with some aging-associated systemic conditions display altered epidermal function, such as reduced stratum corneum hydration levels, which can provoke cutaneous inflammation. Because aged skin exhibits higher expression levels of inflammatory cytokines, which play a pathogenic role in a variety of aging-associated health condition, the association of the skin with some aging-associated disorders is likely mediated by inflammation. This postulation is supported by the evidence that improvement in either epidermal function or inflammatory dermatoses can mitigate some aging-associated disorders such as mild cognitive impairment and insulin sensitivity. This perspective discusses the association of the skin with aging-associated disorders and highlights the potential of improvement in cutaneous conditions in the management of some health conditions in the elderly.

Real-World Treatment Patterns, Resource Use and Costs in Adult Patients With Atopic Dermatitis Receiving Systemic Treatment: Derma-Atopic Study in Spain

BACKGROUND

Moderate-severe atopic dermatitis (AD) has a significant impact on patients' lives, with many requiring systemic treatment to manage symptoms (e.g., pruritus). Several drugs are used off-label to treat AD. This study describes sociodemographic/clinical characteristics, treatment patterns, health resource use (HRU) and costs in adults with AD who initiated systemic treatment or phototherapy in routine practice.

METHODS

This retrospective observational study of electronic medical records in the BIG-PAC database identified adults with prior diagnosis of AD (ICD-9: 691.8 or 692.9) starting oral corticosteroids, immunosuppressants, biologics or phototherapy between 01/01/2012 and 31/12/2016. Patients were followed for 3 years from treatment initiation, up to 31/12/2019. Data on patient characteristics, treatment patterns, HRU and costs were analyzed descriptively.

RESULTS

Patients (N=1995) had a mean age of 60 years, 64% were female, with a mean time of 23 years since diagnosis (84% were ≥18 years at AD onset). Main comorbidities were anxiety (38%), arterial hypertension (36%) and dyslipidemia (35%). Most patients used oral corticosteroids as first systemic (84%; median duration 29 days) and immunosuppressants in 13% of patients (median duration 117 days, 5% cyclosporine and 4% methotrexate). Half of patients required a second line systemic and 12% a third line. The use of immunosuppressants and biologics increased with treatment lines. About 13% of patients received systemic treatments continuously over the 3-year follow-up. The average 3-year per patient cost was 3835 euros, with an average annual cost of 1278 euros.

CONCLUSIONS

Results suggest a high comorbidity and economic burden in this real-world adult population with AD, and the need for systemic treatments indicated for use in AD.

Real-World Treatment Patterns, Resource Use and Costs in Adult Patients With Atopic Dermatitis Receiving Systemic Treatment: Derma-Atopic Study in Spain

Unveiling the true costs and societal impacts of moderate-to-severe atopic dermatitis in Europe

Atopic dermatitis (AD) is a chronic, auto-immune condition that imposes a high burden on individuals, society, and the healthcare system. Approximately 4.4% of adults and up to 18.6% of children/adolescents have AD in Europe, with 20% of all cases accounting for moderate-to-severe forms. This form of the condition in adults results in annual societal costs across Europe of an estimated €30 billion; €15.2 billion related to missed workdays or reduced work productivity, €10.1 billion related to direct medical costs and €4.7 billion related to personal expenditure of patients/families. AD can also substantially impact physical, emotional, and social quality-of-life. Several studies have shown the debilitating itch-scratch cycle is the main cause of the multifaceted burden, as it causes substantial sleep deprivation and stigmatisation due to the physical appearance of the skin, and confidence issues. These factors lead to psychosocial issues and can cumulate over time and prohibit patients reaching their 'full life potential'. Despite this, many patients with the condition are undertreated, resulting in uncontrolled symptoms and a further strain placed on patients, society, and the economy. The authors of this White Paper comprise the European Atopic Dermatitis Working Group, which is a network of international specialists with expertise in dermatology and healthcare policy decisions. Their programme of action is focused on harnessing their expertise to build consensus, advance research, share knowledge, and ultimately seek to improve AD care outcomes through achieving long-term symptom control. This White Paper presents a systematic evaluation of the overall financial and humanistic burden of moderate-to-severe AD and the current challenges that exist with AD care. It introduces recommendations for how, collaboratively, key stakeholders and policy makers can support improvements in AD management to achieve better disease control, thus reducing the costs and associated burden placed on individuals, society, and the economy.

Epidemiology and Economic Burden of Atopic Dermatitis: Real-World Retrospective Data from a Large Nationwide Israeli Healthcare Provider Database

Introduction

Real-world data on the epidemiology and economic burden of atopic dermatitis (AD) are limited. Here we describe the epidemiology and economic burden of AD using electronic healthcare data from Israel.

Methods

A retrospective study was performed using the Maccabi Healthcare Services database. AD incidence in 2008–2017 and point prevalence (AD_prev) on 31 December 2017 were described using diagnosis codes for overall patients, and sex and age subgroups. For AD_prev, severity was defined using recently dispensed treatments for AD. Annual healthcare resource utilization in AD prevalent patients was compared with non-AD matched controls using generalized linear modelling. Direct annual costs were estimated also.

Results

AD incidence was 7.0/1000 person-years; overall prevalence was 4.4% (female patients 4.5%, male patients 4.3%; age 0 to less than 6 months, 0.9%; 6 months to less than 12 years, 11.0%; 12 to less than 18 years, 5.8%; 18 years or older, 2.2%). Among AD_prev (n = 94,483), mild, moderate, and severe AD comprised 57.7%, 36.2%, and 6.1% (adults 43.8%, 46.3%, 9.9%), respectively. Dermatologist and allergist visits and hospitalization rates (at least one) were 40.7%, 6.6%, and 3.8% in 2017. Compared with controls, overall and moderate-to-severe AD were associated with 36% and 52% increases in annual per-person costs (incremental costs $126 and $190).

Conclusions

AD epidemiology in Israel is comparable with other real-world database studies. AD imposes an economic burden that increases with disease severity.

Occurrence and costs of atopic dermatitis in Israel

Atopic dermatitis is a disease that causes the skin to be inflamed and itchy. Atopic dermatitis is most common in children but can also occur in adolescents and adults. Using data from a large healthcare provider in Israel, this study aimed to describe how common atopic dermatitis is within the population. Costs related to the use of healthcare services (such as visits to dermatologists and creams to treat atopic dermatitis) in the year 2017 were compared between persons with versus without atopic dermatitis. For the years 2008 to 2017, approximately 7 out of 1000 people were newly diagnosed with atopic dermatitis each year (incidence). Among people alive on 31 December 2017, 4.4% had atopic dermatitis (prevalence), with 42.3% suggestive of moderate to severe disease. Patients with atopic dermatitis, particularly those with more severe disease, used healthcare services more frequently. Compared with people without atopic dermatitis, medical costs among patients with atopic dermatitis were 36% higher (corresponding to added costs of $126 per person per year). This study helps to better understand how many people have atopic dermatitis, and what healthcare resources are needed to manage this disease.

A Real-World Data Study on the Healthcare Resource Use for Uncontrolled Moderate-to-Severe Atopic Dermatitis in Secondary Care in the United Kingdom Prior to the Introduction of Biologic Treatment

Background

Whilst there is international evidence around the high healthcare resource utilization (HRU) associated with atopic dermatitis (AD), there is a lack of published data from the United Kingdom (UK).

Methods

A retrospective, descriptive, observational study was conducted to evaluate the burden of moderate-to-severe AD on the National Health Service (NHS) in an adult UK population treated with traditional standard of care prior to the introduction of biologics. Patients (n=59) were recruited from 6 UK NHS Hospital Trusts and observed over three years.

Results

707 dermatology clinic visits were recorded over the observation period, amounting to 6.6 visits per patient-year, most commonly for routine check-ups most of which involved dermatology consultants (n=469, 66%). Physicians were the most consulted healthcare professional (n=652, 92%); emollients were the most common treatment (n=80 courses). 174 flares requiring additional medical advice were recorded in total (1.6 per patient-year).

Discussion/Conclusions

Complex treatment pathways for adult patients in the UK with moderate-to-severe AD incur considerable HRU, particularly for those patients non-responsive to systemic therapies with broad immunosuppressant action. Recent advances in biologics-based AD management could possibly have a significant positive impact on HRU through significant reduction in the number of NHS touch points identified in this study.

Clinical and sociodemographic features and quality of life in patients with atopic dermatitis who attended dermatology teaching clinics in Medellín, Antioquia and its metropolitan area

Introduction: Atopic dermatitis is a cutaneous, inflammatory, chronic disease, very frequent in the world and it imposes a high clinical and quality of life impact in patients. To date there are no local studies describing the general features in our population. Objective: To evaluate the socio demographic, clinical and life quality features in patients with atopic dermatitis from Medellín city and its metropolitan area. Materials and methods: cross sectional, descriptive study, that included patients who attended some teaching dermatological clinics. Data collection included sociodemographic and clinical features in addition to clinical issues and quality of life measurements. Results: A total of 13 patients were included. 36,3% manifested a sleeping disturbance, 38,1% attention deficit; 44,2% reported asthma in the childhood. EASI and SCORAD scores were 6,9 and 32,4, respectively, which indicates a mild-moderate compromise. Regarding quality of Life, Skindex-29 showed average scores for the symptomatic, emotional and functional dominions of 37,7, 25,09 and 16,9, respectively, and a total score of 24,78. In EQ-5D scores, the most altered component was the presence of pain or discomfort (17,6%) and the presence of anxiety or depression (12,1%), which enhances the symptomatic and emotional impact of the disease. Conclusion: These results confirm that patients with atopic dermatitis present similar features to those reported in other studies from different countries, highlighting the burden of the disease in adults and its impact in neuropsychiatric and emotional domains.

Atopic dermatitis and psychosocial comorbidities - What's new?

Atopic dermatitis (AD) is a chronic inflammatory disease. During the last years, researchers have focused on a variety of associated comorbidities, especially psychosocial disease. This article aims at giving an overview over recent data. A systematic literature research was performed in PubMed including data from the time period January 1, 2018 until March 1, 2020. Patients with AD frequently suffer from cocomitant depression, anxiety, and attention deficit hyperactivity disorder. There is less evidence about the relation between AD and schizophrenia, eating disorder, and obsessive compulsive disorder. There is still great need for research in the connection between AD and psychosocial disease, particularly about the pathogenesis and the influence of new therapies.

The Economic and Psychosocial Comorbidity Burden Among Adults with Moderate-to-Severe Atopic Dermatitis in Europe: Analysis of a Cross-Sectional Survey

Introduction

Atopic dermatitis (AD) is a common inflammatory disease of the skin, which may have a substantial impact on patients' health-related quality of life (HRQoL). The aim of this study was to quantify the economic burden (direct and indirect costs) of moderate-to-severe AD and evaluate the prevalence and impact of psychosocial comorbidities among patients in the European Union-5 (France, Germany, Italy, Spain, and the UK).

Methods

Data were analyzed from the 2017 EU5 National Health and Wellness Survey. Respondents with a physician diagnosis of AD/eczema who were considered to have moderate-to-severe AD based on a Dermatology Life Quality Index (DLQI) score  ≥ 6 were included. Direct costs, indirect costs, and psychosocial comorbidities (sleep difficulties and anxiety based on self-report, depression based on the Patient Health Questionnaire-9) were reported descriptively. Generalized linear models were used to examine the relationship between psychosocial comorbidities and health outcomes (the Short Form-36 version 2 [SF-36v2], EuroQoL 5-dimension 5-level, Work Productivity and Activity Impairment questionnaire, and healthcare resource utilization).

Results

Overall, 1014 patients were included in the analysis. Total annual direct costs ranged from €2242 to €6924 and total annual indirect costs ranged from €7277 to €14,236, depending on the level of disease severity. Sleep difficulties, anxiety, and depression were reported by 61.6%, 52.7%, and 75.8% of patients, respectively. These comorbidities were significantly associated with reduced physical and mental component summary scores from SF-36v2 and increased overall work impairment (p < 0.05 for all).

Conclusions

A significant economic burden was observed for patients with moderate-to-severe AD. Sleep difficulties, depression, and anxiety were observed in more than half of moderate-to-severe AD patients and were significantly associated with decrements in HRQoL and with work-related impairment. Reducing the burden of these psychosocial comorbidities in AD could have significant benefit to patients and society.

Psychosocial burden and out-of-pocket costs in patients with atopic dermatitis in Ireland

Atopic dermatitis (AD) is one of the most common inflammatory skin diseases in the developed world, affecting 1-3% of the adult population in Europe. This inflammatory disease can have a marked impact on affected individuals, leading to significant impairment in physical wellbeing and quality of life (QoL). The aim of this study was to investigate the psychosocial impact and financial burden of AD on patients in Ireland. To increase our understanding of the psychosocial and financial aspects of AD disease burden in the Irish population, an online survey was designed. The survey was launched by the Irish Skin Foundation, and included questions focusing on disease severity, disease control, psychosocial impact, interrupted sleep, missed work and school days, and financial cost. The survey showed that the impact of AD on QoL was profound. The survey demonstrated that 85% of adults described interrupted sleep, 70% reported social anxiety, 65% avoid exercise and sports, 52% avoid social activities, 52% avoid sexual intimacy and 43% feel they are depressed as a result of their AD. Approximately one-quarter of those surveyed can spend up to €2300 annually on over-the-counter, prescription and alternative treatments. This study has shown the significant impact AD has on patients living in Ireland. It also highlights that out-of-pocket costs for patients is higher compared with previous studies across European countries.

Atopic dermatitis in specialized centers in Spain: a retrospective analysis of incidence and costs (2000-2017)

BACKGROUND

Atopic dermatitis is a chronic inflammatory skin disease that has substantial effects on patients' quality of life, with a prevalence between 2.2% and 17.6% worldwide. This study aimed to evaluate the use of specialized care resources generated by children and adults with atopic dermatitis, and the associated direct medical costs.

METHODS

Admission details from patients admitted in specialized healthcare centers (inpatient and outpatient care) in Spain between 1 January 2000 and 31 December 2017 were analyzed in a retrospective multicentre study.

RESULTS

Records corresponded to 3036 patients, 1266 aged 5 years or younger. Comorbid conditions corresponded to skin infections and respiratory difficulties (asthma, bronchiectasis). Hospital incidence of atopic dermatitis was 5.8 per 100,000 persons, stable over the study period, and 30.0 per 100,000 in those aged 5 years and younger. Mean annual direct medical cost per patient was €2469. Overall, direct medical costs per patient increased significantly over the study period (p < 0.0001).

CONCLUSION

Hospital incidence of atopic dermatitis remained stable over the study period, which is in contrast with the increasing incidence reported by the Spanish government in primary care centers. The increase in direct medical costs of specialized care responded to the increase in treatment costs.

Analisi costo-utilità di dupilumab per il trattamento della dermatite atopica grave negli adulti in Italia

Background:

Atopic dermatitis (AD) is a chronic, multifactorial, inflammatory skin disease with significant impact on patients’ quality of life.

Objective:

The objective of this analysis was to estimate the incremental cost-utility ratio (ICUR) of dupilumab, administered every other week, plus supportive care (SC), vs SC, in the Italian adult population with severe AD, for whom ciclosporin treatment is contraindicated, ineffective or not tolerated.

Methods:

Simulation of outcomes and costs was conducted using a 1-year decision tree, followed by a lifetime horizon Markov model. Clinical data were derived from a pooled analysis of two studies. The analysis was conducted adopting the Italian National Health Service (NHS) perspective. In the model, the following costs were considered: i) Drug acquisition costs; ii) Disease management costs; iii) Costs of adverse events. Robustness of findings was tested using both one-way deterministic and probabilistic sensitivity analyses.

Results:

In the base case, dupilumab plus SC was more effective than SC (+2.42 quality adjusted life years, QALYs). The total lifetime cost per patient treated with dupilumab was higher than SC (€ 137,267 and € 56,744, respectively). Dupilumab plus SC was cost-effective vs. SC, with an ICUR of € 33,263 per QALY gained. The ICUR fell in the informal range of ICUR acceptability proposed for Italy (range: € 25,000-€ 40,000 per QALY gained). Sensitivity analyses confirmed robustness and reliability of base case results.

Conclusions:

Dupilumab plus SC is a cost-effective option for the treatment of patients with severe AD in Italy, compared with SC, when NHS perspective is considered.

Atopic Eczema in Adulthood and Risk of Depression and Anxiety: A Population-Based Cohort Study

BACKGROUND

Atopic eczema is a common and debilitating condition associated with depression and anxiety, but the nature of this association remains unclear.

OBJECTIVE

To explore the temporal relationship between atopic eczema and new depression/anxiety.

METHODS

This matched cohort study used routinely collected data from the UK Clinical Practice Research Datalink, linked to hospital admissions data. We identified adults with atopic eczema (1998-2016) using a validated algorithm, and up to 5 individuals without atopic eczema matched on date of diagnosis, age, sex, and general practice. We estimated the hazard ratio (HR) for new depression/anxiety using stratified Cox regression to account for age, sex, calendar period, Index of Multiple Deprivation, glucocorticoid treatment, obesity, smoking, and harmful alcohol use.

RESULTS

We identified 526,808 adults with atopic eczema who were matched to 2,569,030 without. Atopic eczema was associated with increased incidence of new depression (HR, 1.14; 99% CI, 1.12-1.16) and anxiety (HR, 1.17; 99% CI, 1.14-1.19). We observed a stronger effect of atopic eczema on depression with increasing atopic eczema severity (HR [99% CI] compared with no atopic eczema: mild, 1.10 [1.08-1.13]; moderate, 1.19 [1.15-1.23]; and severe, 1.26 [1.17-1.37]). A dose-response association, however, was less apparent for new anxiety diagnosis (HR [99% CI] compared with no atopic eczema: mild, 1.14 [1.11-1.18]; moderate, 1.21 [1.17-1.26]; and severe, 1.15; [1.05-1.25]).

CONCLUSIONS

Adults with atopic eczema are more likely to develop new depression and anxiety. For depression, we observed a dose-response relationship with atopic eczema severity.

Severe Atopic Dermatitis In Spain: A Real-Life Observational Study

OBJECTIVE

To determine the epidemiology and characterize the treatment prescribed for severe atopic dermatitis (AD) in children/adults in usual clinical practice.

METHODS

Observational, retrospective study made through review of medical records of Spanish patients aged ≥6 years. Patients diagnosed with severe AD who required care between 2013 and 2017 were included. The study groups were: 6-12 years; 13-18 years; and > 18 years. Patients were followed for 5 years. The main measurements were the prevalence of AD, comorbidity and treatment duration. Statistical significance was established as p <0.05.

RESULTS

We included 2323 patients with severe AD. The overall prevalence was 0.10% (95% CI: 0.09-0.11%) and was 0.39%, 0.23% and 0.07% in the 6-12 years, 13-18 years and >18 years age groups, respectively (p <0.001), the percentage of males was 58%, 48.6% and 39%, respectively, and general comorbidity was 0.1, 0.2 and 0.9 points, respectively (p <0.001).The most frequent comorbidities were asthma in 49.0%, 44.9% and 20.8%, respectively (p <0.001), and anxiety in 79.7%, 65.8% and 67.3%, respectively (p <0.001). Oral corticosteroids were administered in 97.3%, 90.9% and 81.7%, respectively (concomitant-medication). Cyclosporine (45.3%), azathioprine (15.9%) and methotrexate (9.0%) were the most frequently prescribed drugs; biologic agents were administered in 5.8% of patients (for AD).

CONCLUSION

In AD the presence of comorbidities was significant, especially in the psychological, immunoallergic and cardiovascular areas. Cyclosporine was the most widely used immunosuppressant. There was a degree of variability in the use and duration of the treatments prescribed.
