Abstract
The opinions of patients with allergic skin diseases often determine their attitudes to treatment. However, little is known about the viewpoints of patients and their concerns regarding their conditions. This novel study is the first to compare relationships between the opinions of patients and their concerns regarding the severity of atopic dermatitis or chronic spontaneous urticaria and the presence or absence of biologics. We also compared and clarified the characteristics of these diseases using a questionnaire that was completed by 359 patients treated at university and city hospitals, as well as dermatology clinics. Covariance analysis was performed to compare both diseases with different backgrounds. Patients with adult atopic dermatitis were more likely than those with chronic idiopathic urticaria to believe that treatment must be continued and that the disease will not spontaneously improve. Patients with severe or poorly controlled atopic dermatitis or chronic spontaneous urticaria often had psychosomatic symptoms and also believed that the disease required continued treatment. Social factors related to wait times and medication were not associated with disease severity. Patients receiving treatment had significantly less anxiety associated with biologics than those who did not receive treatment. Patients with atopic dermatitis had higher physical and mental burden than those with chronic spontaneous urticaria. Therefore, effective treatments must be prescribed. Consideration of these disease-specific characteristics regarding the opinions and concerns of patients can improve patient satisfaction and compliance with treatment, which results in favorable outcomes.
Introduction
The views that patients have of an illness is a phenomenon consisting of multiple dimensions that overlap but are independent of each other [1]. Atopic dermatitis (AD) is a skin allergy with a high disease burden that decreases the quality of life of patients. In addition, doctors and patients differently rate treatment goals and satisfaction with treatment [2, 3]. Urticaria is a common skin disorder. It mostly comprises acute and chronic spontaneous types that cause wheals to develop over the course of a day or for ≥6 weeks, respectively [4]. Compliance with treatment of chronic spontaneous urticaria (CSU) is poor when symptoms improve [4], which might be owing to the attitudes of patients [4]. If patients are not eager to treat the disease, they might not be optimistic about or compliant with treatment. In addition, how AD and CSU are perceived by doctors and patients differ. Previous interview viewpoints have shown that patients believe the disease “is like the bad guy in a movie that refuses to die” [5].
This report describes the results of a survey of patients with AD and CSU regarding medication compliance using the Physician Global Assessment (PGA), itch numerical rating scale (NRS), and opinions and concerns that patients have about the disease. The effects of patient-reported outcomes, treatment methods, and other factors on patient perceptions of the disease were analyzed. Insights and concerns regarding each disease were also compared.
Methods
Patients
This study included 359 patients who were diagnosed with AD or CSU according to the respective guidelines for these diseases [6, 7]. All patients were treated at the Department of Dermatology of Shimane University Hospital, Masuda Red-Cross Hospital, Kyushu University Hospital, Sapporo Medical University Hospital, Sumikawa Dermatology and Allergy Clinic, Kobe University Hospital, and Kyoto Prefectural University of Medicine University Hospital between May 2020 and February 2022. Patient data were anonymized before analysis.
Inclusion and exclusion criteria
The inclusion criteria comprised age ≥15 years, diagnosis of AD or CSU, and ability to respond to the questionnaire. The exclusion criteria comprised age <15 years and unable to respond to the questionnaire.
Questionnaire
Patients completed a questionnaire developed for this study (Table 1) and described their diagnosis and disease severity using the PGA, which provides a composite score on a scale of 0–4. The questionnaire was self-administered and included multiple-choice items regarding age, sex, occupation, annual income, educational level, lifestyle, and disease duration. A section based on the Patient-Oriented Eczema Measure (POEM) was also included [6, 8]. Mild, moderate, and severe AD was defined by POEM scores of <7, 8–16, and >16, respectively. Symptom control was assessed using the self-administered urticaria control test (UCT) [7, 9]. Patients with CSU who had UCT scores of <12 and ≥12 were, respectively, classified as having poorly and well-controlled disease. Patients described their current medications, willingness to undergo treatment, and satisfaction with the treatment plan using an 11-point scale. Their opinions and concerns regarding their disease were described using a 5-point scale.

Statistical analysis
All data were statistically analyzed using R 4.0.3 software [10]. Statistical significance was set at p < 0.05. The characteristics of patients with AD and CSU were compared. Continuous variables are presented as means and standard deviations or as medians and interquartile ranges. Categorical variables are presented as numbers and ratios (%).
The basic characteristics of each disease were compared using Mann–Whitney U tests. The responses of the patients to POEM were compared using Kruskal–Wallis tests. The UCT results and differences between biologic treatments were compared using Wilcoxon rank sum tests.
As disease severity significantly impacts the opinions and concerns of patients, we adjusted the data for severity, age, and sex and used analyses of covariance (ANCOVA) for comparisons.
Results
Analysis of patients
This study included 359 patients, of which 202 had AD (113 men and 89 women; mean age: 39.3 ± 13.6 years) and 157 had CSU (51 men and 106 women; mean age: 48.5 ± 17.0 years) (Table 2). The PGA scores were higher in patients with AD than with CSU (p < 0.001, Mann–Whitney U test) and significantly correlated with POEM (p < 0.001, Kruskal–Wallis test) and UCT (p < 0.001, Wilcoxon rank sum test) scores (Tables 2, 3). The motivation to undergo treatment and ratio of patients who believed that the disease would be cured was higher among those with CSU than with AD (p < 0.001 Mann–Whitney U test).

Opinions and concerns of patients regarding AD and CSU based on their reported outcomes
Patient age, sex, disease duration, income, willingness to undergo treatment, and ratio of those who believed that they would be cured were not related to the POEM scores. The itch NRS was associated with the POEM score (p < 0.001). Significantly more patients with low POEM scores were treated with biologics than in the other groups (p < 0.001). Patients with high POEM scores were more likely to report psychological problems (p = 0.012), difficulty with their disease (p < 0.001), and that continued treatment was necessary (p < 0.001; Table 4). Patients with high POEM scores were significantly more concerned about physical symptoms, such as itching and pain, and psychological symptoms, such as mental distress (p < 0.001). However, social factors, such as long waits for medical treatment, being unable to confide in a doctor, and concerns regarding medications were not related to the POEM scores (Table 5).

Wilcoxon rank sum test.
Patients with well-controlled CSU were older (p < 0.001), had lower itch NRS scores (p < 0.001), and were more likely to believe that the disease would be cured (p < 0.001) than those with poorly controlled CSU. Sex, disease duration, income, and willingness to undergo treatment were not associated with the UCT scores. The rate of biologic treatment was significantly higher among patients with well-than poorly controlled CSU (p < 0.023). Patients in the latter group more often reported that continued treatment of CSU is necessary and that the disease was “like a movie villain who does not die easily” than those with well-controlled CSU (Table 4). Physical symptoms, such as itching and pain, and psychological symptoms, such as mental distress, were significantly more frequent in the poorly than in the well-controlled group. However, no social factors were associated with the UCT scores (Table 5).
Patients’ opinions and concerns regarding AD and CSU based on the use of biologics
Dupilumab was prescribed to 41 patients with mild AD. Patients who were treated were significantly older (p = 0.005) and had a longer disease duration (p < 0.001) and lower itch NRS scores (p < 0.001) than those who were not treated with this biologic. Opinions of AD did not significantly different between patients treated with biologics and those who were not (Table 6). Patients who were treated with biologics were less likely to report concerns regarding itching (p = 0.02), various symptoms (p = 0.008), symptoms that did not improve (p < 0.001), repeated exacerbation/remission cycles (p = 0.002), mental stress (p = 0.032), discomfort with their appearance (p = 0.006), and anxiety regarding their treatment (p < 0.001). However, the belief that few patients had the same disease and concerns regarding the cost of treatment were significantly more frequent among patients treated with biologics than those who were not (Table 7).

Significant difference tests between patients with and without biologics for each problem.
Wilcoxon rank sum test.
Omalizumab was prescribed to 46 patients with CSU. Patients treated with this biologic were significantly older (p < 0.001) than those who were not. Significantly more females with CSU were prescribed omalizumab than no biologic (p = 0.035). The itch NRS score was lower (p = 0.028) among patients treated with omalizumab than among those who were not. In addition, patients treated with omalizumab were more willing to undergo treatment (p < 0.001) and more likely to believe that the disease would be cured (p = 0.001) than those who were not treated with this biologic. Patients who were treated with omalizumab were highly likely to describe CSU as “a movie villain who does not die easily” and express difficulty with the disease (Table 6). Fewer patients treated with omalizumab reported anxiety regarding the use of biologics, although more reported believing that few patients had the same disease and that they had concerns about mental distress and the cost of treatment (Table 7).
Comparison of disease effects on opinions and concerns of patients
The ANCOVA results showed that patients with CSU were significantly more willing to seek medical treatment (p = 0.035) and more likely to believe that their illness would be cured (p = 0.003) than those with AD. More patients with CSU expressed the opinion that their disease could be cured naturally than those with AD (Table 8). Physical symptoms were frequent in patients with AD. Concerns regarding exacerbating factors, ointment application, and anxiety regarding topical steroids were more prevalent among patients with CSU than those with AD (Table 9).

Discussion
Patients’ images of disease are currently being investigated as narrative-based medicine [11]. In addition, since medication compliance increases with treatment satisfaction, images of a disease might also be associated with compliance [12]. The opinions of patients about diseases have been investigated in the fields of psychiatry [1] and diabetes [13]. By contrast, information about such opinions, particularly about allergic diseases, is scant in the field of dermatology. Therefore, our findings contain valuable information. Medication compliance is essential to effectively treat AD and CSU. Increasing patient satisfaction with treatment and their realization of the beneficial effects of drugs improve their compliance [12, 14], as we showed herein. We also found that patients who applied biologics reported fewer symptoms, although the cost of treatment was a concern. These findings suggested that the high cost of biologics forces patients to choose between paying for treatment or experiencing symptoms. In addition, fewer patients described anxiety regarding the application of biologics. The severity of AD and treatment satisfaction correlated in a study that assessed patients using the Treatment Satisfaction Questionnaire for Medication [15]. Reducing disease severity increases patient satisfaction and adherence to treatment regimens, creating a cycle that results in sufficient therapeutic effects.
Psychosocial effects (such as isolation, sociability, stigma, effects of illness on activity, and hopelessness) and noncompliance can be used to identify patients with psoriasis who require additional support to overcome issues with treatment compliance [16]. We did not identify any correlations between the opinions and concerns of patients regarding AD or CSU. Disease severity often correlates with the opinions and concerns of patients, as the present study also found. These findings highlight the importance of relieving symptoms to improve patient opinions of the disease. We evaluated viewpoints and concerns before and after treatment with biologics in a small subset of patients (data not shown). Although the subset was small, the findings suggested that symptomatic relief owing to treatment improved the opinions and reduced the concerns of patients regarding their disease.
That mental illness also correlates with severity is a notable concern (Table 5), and psychosomatic therapy is important in treating allergic diseases. However, not many allergists practice psychosomatic therapy. Allergic diseases associated with psychosomatic disorders are often severe or refractory to treatment with a conventional bio-medical model. A psychosomatic diagnosis and treatment are necessary according to the psycho-socio-eco-medical model of disease understanding [17].
Atopic dermatitis is an inflammatory skin disease that affects over 1 in 10 children in Japan [6]. Although it is believed that AD remits with age, epidemiological studies have found that AD follows a lifelong episodic course when it presents after the age of 12 years [18, 19]. A gradual change in treatment expectations from cure to control is associated with a long-term acceptance of AD and a hope of being cured [5]. By increasing awareness regarding the long-term nature of eczema among adolescents, effective self-care habits can be encouraged [5]. Our patients did not report the belief that AD improves naturally, which might be because adults with AD were included in the study and AD often cannot be cured if it presents in adulthood. By contrast, patients were more likely to report the belief that CSU naturally improves, which corresponded to the median duration of CSU being 4 years.
The viewpoints and concerns of the patients were subjectively evaluated. Therefore, a comparator was included to increase understanding of the significance of our findings. Therefore, we compared the viewpoints and concerns of patients with AD and CSU using a multivariate analysis. More patients with CSU reported that the symptoms naturally improves, as eruptions appear and disappear. Many patients agreed that the image of disease presented in the other questions applied to AD. More patients with AD reported concerns regarding their physical and mental symptoms than those with CSU. Patients with AD reported concerns regarding antihistamines, which lead to less noticeable effects in patients with AD than in those with CSU. In addition, patients with CSU reported concerns regarding topical drugs, which are not recommended in international [9] or Japanese [7] guidelines. These guidelines must be adhered to in clinical practice.
This study is not without limitations. Patients who responded to the questionnaire were seen by dermatologists and allergists at hospitals offering relatively innovative care. This could have affected the range of treatment choices. All our patients were old enough to answer questions, which might have introduced bias. Simple comparisons between AD and CSU were difficult because of differences in mean disease activity, so analysis of covariance (ANCOVA) was performed to compare the two diseases.
In conclusion, patients’ opinions and concerns differ based on specific diseases. Patients’ opinions are influenced by disease severity and types of treatment. Patients were concerned about ineffective treatment. Understanding these characteristics can be used to improve patient satisfaction and compliance, ultimately resulting in favorable outcomes.
