Risk of developing psychiatric disease among adult patients with skin disease: A 9-year national register follow-up study in Norway.

Background: The existing association between skin disease and psychiatric comorbidity has gained attention during the last decades. Stress and mental illness can directly or indirectly affect skin disease, while dermatological conditions, known to impair life quality and mental well-being, can promote psychiatric conditions. Objectives: The aim of this study was to assess the risk of developing psychiatric disease among adult dermatological patients over a period of time. The secondary objective was to see which psychiatric disorders developed most commonly, and which skin diseases posed the greatest risk for later mental health issues. Methods: Adult dermatological patients were followed for 9 years (2008-2016) using the Norwegian Patient Registry, for both outpatient and inpatient specialist healthcare services. Dermatological patients were identified during the first 2 years and were then followed for psychiatric comorbidity prospectively for the next 7 years.Cox regression models were applied to estimate the risks of psychiatric disorders among patients with skin diseases. Estimates were adjusted for age and gender differences. Hazard risk ratios (HR) with 95% CI are reported. Results: Dermatological patients developed depressive disorders most frequently (4.1% vs. 2.3% in non-dermatological participants), followed by anxiety disorders (3.3% vs. 1.8%), and adjustment disorders (2.6% vs. 1.5%). Developing depressive disorders showed the highest HR among dermatological patients, HR (95% CI) = 2.5 (2.4-2.5), followed by disorders related to alcohol use, HR (95% CI) = 2.2 (2.1-2.5), and anxiety disorders, HR (95% CI) = 2.1 (2.1-2.2). Papulosquamous disorders were the skin conditions with the highest HR for developing a mental health condition, with depressive disorder having HR (95% CI) = 2.6 (2.5-2.9); anxiety disorders at HR (95% CI) = 2.9 (2.7-3.1); and disorders related to alcohol use at HR (95% CI) = 3.2 (2.8-3.6). Conclusions: The study demonstrates that having a skin disease doubles to triples the risk of developing a psychiatric illness within 7 years, especially depression, anxiety, and alcohol use compared with the general population.

Perceived Stigmatization among Dermatological Outpatients Compared with Controls: An Observational Multicentre Study in 17 European Countries.

Perceived stigmatization places a large psychosocial burden on patients with some skin conditions. Little is known about the experience of stigmatization across a wide range of skin diseases. This observational cross-sectional study aimed to quantify perceived stigmatization and identify its predictors among patients with a broad spectrum of skin diseases across 17 European countries. Self-report questionnaires assessing perceived stigmatization and its potential predictors were completed by 5,487 dermatology outpatients and 2,808 skin-healthy controls. Dermatological diagnosis, severity, and comorbidity were clinician-assessed. Patients experienced higher levels of perceived stigmatization than controls (p < 0.001, d = 0.26); patients with psoriasis, atopic dermatitis, alopecia, and bullous disorders were particularly affected. Multivariate regression analyses showed that perceived stigmatization was related to sociodemographic (lower age, male sex, being single), general health-related (higher body mass index, lower overall health), disease-related (higher clinician-assessed disease severity, presence of itch, longer disease duration), and psychological (greater distress, presence of suicidal ideation, greater body dysmorphic concerns, lower appearance satisfaction) variables. To conclude, perceived stigmatization is common in patients with skin diseases. Factors have been identified that will help clinicians and policymakers to target vulnerable patient groups, offer adequate patient management, and to ultimately develop evidence-based interventions.

Perceived stress in patients with inflammatory and non-inflammatory skin conditions. An observational controlled study among 255 Norwegian dermatological outpatients.

Background: Inflammation may increase stress, while stress may promote inflammation. Most dermatological conditions are chronic and inflammatory, while some, such as cancer, naevi and tumours are non-inflammatory, but may cause stress because of the fear of malignancy and the necessity for surgical and other invasive treatments. Stress among patients with skin diseases is little explored. Objectives: To assess perceived stress in patients with inflammatory and non-inflammatory skin conditions compared to healthy controls. Methods: Observational cross-sectional study. Consecutive outpatients (N = 255) visiting the Department of Dermatology, Stavanger University Hospital, Norway and 148 skin-healthy controls contributed by answering questionnaires on sociodemographics, stressful life events, economic difficulties, self-rated health and perceived stress. The validated Perceived Stress Scale10 was used to evaluate stress. A dermatologist examined patients and registered their diagnoses and comorbidities. Controls included in this study were not examined by a dermatologist and self-reported their comorbidities. Results: Patients with an inflammatory skin disease or psoriasis have a tripled risk of reporting moderate to high stress compared with controls when adjusted for relevant confounders, including having experienced a stressful life event recently or having a comorbidity. Patients with a purely non-inflammatory skin disease perceived stress no differently than controls. Conclusion: Patients with inflammatory skin disease perceived higher stress than controls and patients with non-inflammatory skin conditions. Dermatologists may play a role in awareness of the importance of stress in skin disease.

Body dysmorphia in common skin diseases: results of an observational, cross-sectional multicentre study among dermatological outpatients in 17 European countries.

BACKGROUND: Body dysmorphic disorder (BDD) is a common psychiatric disorder associated with high costs for healthcare systems as patients may repeatedly ask for different, often not effective, interventions. BDD symptoms are more prevalent in patients with dermatological conditions than in the general population, but there are no large sample studies comparing the prevalence of BDD symptoms between patients with dermatological conditions and healthy skin controls. OBJECTIVES: To compare the prevalence of BDD symptoms between patients with different dermatological conditions and healthy skin controls and to describe sociodemographic, physical and psychological factors associated with BDD symptoms to identify patients who may have a particularly high chance of having this condition. METHODS: This observational, cross-sectional, comparative multicentre study included 8295 participants: 5487 consecutive patients with different skin diseases (56% female) recruited among dermatological outpatients at 22 clinics in 17 European countries, and 2808 healthy skin controls (66% female). BDD symptoms were assessed by the Dysmorphic Concern Questionnaire. Sociodemographic data and information on psychological factors and physical conditions were collected. Each patient was given a dermatological diagnosis according to ICD-10 by a dermatologist. The study was registered with number DRKS00012745. RESULTS: The average participation rate of invited dermatological patients was 82.4% across all centres. BDD symptoms were five times more prevalent in patients with dermatological conditions than in healthy skin controls (10.5% vs. 2.1%). Patients with hyperhidrosis, alopecia and vitiligo had a more than 11-fold increased chance (adjusted Odds Ratio (OR) > 11) of having BDD symptoms compared with healthy skin controls, and patients with atopic dermatitis, psoriasis, acne, hidradenitis suppurativa, prurigo and bullous diseases had a more than sixfold increased chance (adjusted OR > 6) of having BDD symptoms. Using a logistic regression model, BDD symptoms were significantly related to lower age, female sex, higher psychological stress and feelings of stigmatization. CONCLUSIONS: Clinical BDD symptoms are significantly associated with common dermatological diseases. As such symptoms are associated with higher levels of psychological distress and multiple unhelpful consultations, general practitioners and dermatologists should consider BDD and refer patients when identified to an appropriate service for BDD screening and management.

Exploring the EQ-5D Dimension of Pain/Discomfort in Dermatology Outpatients from a Multicentre Study in 13 European Countries.

Pain and discomfort are important symptoms in dermatology. The aim of this cross-sectional, multicentre study was to describe the prevalence of pain/discomfort and its associations in patients with several dermatological conditions across 13 European countries. The outcome was the prevalence of pain/discomfort according to a question of the EQ-5D questionnaire. Data collected from November 2011 to February 2013 were complete for 3,509 consecutive outpatients. Moderate or extreme pain/discomfort was reported by 55.5% of patients and 31.5% of controls with no skin conditions. The highest proportions were reported by patients with hidradenitis suppurativa (92.9%), leg ulcer (81.4%), prurigo (80%) and lichen planus (75.6%). Pain/discomfort was associated with older age, low educational level, clinical severity, flare on scalp or hands, itch, depression, anxiety, low quality of life, and thoughts of suicide. It is important to enquire specifically about pain/discomfort during clinical consultations and to address it when planning a patient's care.

Subjective and Objective Characteristics of Patients Seen at a Psychodermatology Unit: One-year Experience in Malmö, Sweden.

Clinical epidemiological knowledge concerning psychodermatology patients is scarce. The objective of this study was to assess morbidity in a new psychodermatology service. Information was gathered from patient records at the psychodermatology unit in Skåne University Hospital, Malmö, Sweden, from 1 February 2017 to 31 January 2018. All patients were screened with the Hospital Anxiety and Depression Scale (HADS) and the Dermatology Life Quality Index (DLQI) at baseline and after 12 months. Additional information was collated from the patient records. A total of 50 patients were treated during the 12 months, 86% were women, mean age 44 years (standard deviation (SD) 16 years). Itch was present in 72% of patients. Forty-two percent of patients were diagnosed with mood disorders, 30% with personality disorders, and 16% with delusional disorders. At baseline 40% of patients had a DLQI score >11, clinical depression was present in 14%, and clinical anxiety in 28%. These data emphasize the need for access to a multidisciplinary unit for dermatology patients.

Psychosocial Aspects of Adult Acne: Data from 13 European Countries.

The link between acne and psychiatric morbidities has been demonstrated in many studies; however, large scale studies aiming to reveal the psychosocial impact of acne are rare. The aim of this study was to assess the psychological burden of adult acne patients. This analysis was based on a multicenter study including 213 acne patients and 213 controls from 13 European countries. The Hospital Anxiety and Depression Scale (HADS), Dermatology Life Quality Index, and EuroQol 5 dimensions 3 levels scores of the patients with acne were analyzed. Patients with acne (n = 213) had higher HADS scores for anxiety (mean ± standard deviation 6.70 ± 3.84) and depression (3.91 ± 3.43) than the controls (p < 0.001 for both). For patients with acne, 40.6% reported that they were very concerned about their skin disease, 12.3% had suicidal ideation, and, among those, 10 (4%) patients implied that acne was the cause of their suicidal thoughts. After adjusting for other variables, patients who had suicidal ideation (p = 0.007, and adjusted odds ratio 3.32 [95% confidence interval (CI): 1.39-7.93]) and stressful life events (p < 0.001, and adjusted OR 5.85 [95% CI: 2.65-12.86]) had a greater chance of fulfilling the HADS criteria for anxiety. This study highlights the need for a psychotherapeutic approach in order to recognize the concerns of acne patients and optimize their treatment.

Itch and Mental Health in Dermatological Patients across Europe: A Cross-Sectional Study in 13 Countries.

Itch is a highly prevalent and multidimensional symptom. We aimed to analyze the association between itch and mental health in dermatological patients. This multicenter study is observational and cross-sectional and was conducted in dermatological clinics across 13 European countries. A total of 3,530 patients and 1,094 healthy controls were included. Patients were examined clinically. Outcome measures were itch (presence, chronicity, and intensity), the Hospital Anxiety and Depression Scale, EQ-5D visual analogue scale, sociodemographics, suicidal ideation, and stress (negative life events and economic difficulties). Ethical approval was obtained. Results showed significant association between the presence of itch in patients and clinical depression (odds ratio, 1.53; 95% confidence interval, 1.15-2.02), suicidal ideation (odds ratio, 1.27; 95% confidence interval, 1.01-1.60), and economic difficulties (odds ratio, 1.24; 95% confidence interval, 1.10-1.50). The mean score of reported generic health status assessed by the EQ-5D visual analogue scale was 65.9 (standard deviation = 20.1) in patients with itch, compared with 74.7 (standard deviation = 18.0) in patients without itch (P < 0.001) and 74.9 (standard deviation = 15.7) in controls with itch compared with 82.9 (standard deviation = 15.6) in controls without itch (P < 0.001). Itch contributes substantially to the psychological disease burden in dermatological patients, and the management of patients should include access to multidisciplinary care.

Burden of Atopic Dermatitis in Swedish Adults: A Population-based Study.

The burden of atopic dermatitis (AD) was assessed. A population-based, cross-sectional questionnaire study was performed among 34,313 Swedish adults in 2017. The prevalence of AD was 14%. Adults with mild AD had an increased relative risk ratio (RRR) of severe depression (aRRR 1.78, 95% confidence interval (95% CI) 1.50-2.12) and anxiety (aRRR 1.97, 95% CI 1.69-2.30), which was higher for severe AD (aRRR 6.22 95% CI 4.60- 8.42, aRRR 5.62 95% CI 4.10-7.71, respectively). Persons with severe AD were less likely to have a university degree (aRRR 0.55, 95% CI 0.34-0.90) and more likely to have a lower annual income (238,000-324,000 SEK: aRRR 0.51, 95% CI 0.39-0.77; 325,000 SEK or more 0.36; 0.25-0.58) compared with individuals without AD. These results suggest that AD implies an increased prevalence of comorbid mental conditions and an adverse impact on academic achievement and work. These adverse associations increase substantially for patients with severe AD and comorbid asthma.

European S2k Guideline on Chronic Pruritus.

Pruritus is a frequent symptom in medicine. Population-based studies show that every 5th person in the general population has suffered from chronic pruritus at least once in the lifetime with a 12-month incidence of 7%. In patient populations its frequency is much higher depending on the underlying cause, ranging from around 25% in haemodialysis patients to 100% in skin diseases such as urticaria and atopic dermatitis (AD). Pruritus may be the result of a dermatological or non-dermatological disease. Especially in non-diseased skin it may be caused by systemic, neurological or psychiatric diseases, as well as being a side effect of medications. In a number of cases chronic pruritus may be of multifactorial origin. Pruritus needs a precise diagnostic work-up. Management of chronic pruritus comprises treatment of the underlying disease and topical treatment modalities, including symptomatic antipruritic treatment, ultraviolet phototherapy and systemic treatment. Treating chronic pruritus needs to be targeted, multimodal and performed in a step-wise procedure requiring an interdisciplinary approach. We present the updated and consensus based (S2k) European guideline on chronic pruritus by a team of European pruritus experts from different disciplines. This version is an updated version of the guideline that was published in 2012 and updated in 2014 (www.euroderm.org).

Occurrence, Chronicity and Intensity of Itch in a Clinical Consecutive Sample of Patients with Skin Diseases: A Multi-centre Study in 13 European Countries.

Itch is an unpleasant symptom, affecting many dermatological patients. Studies investigating the occurrence and intensity of itch in dermatological patients often focus on a single skin disease and omit a control group with healthy skin. The aim of this multi-centre study was to assess the occurrence, chronicity and intensity (visual analogue scale 0-10) of itch in patients with different skin diseases and healthy-skin controls. Out of 3,530 dermatological patients, 54.3% reported itch (mean ± standard deviation itch intensity 5.5 ± 2.5), while out of 1,094 healthy-skin controls 8% had itch (3.6 ± 2.3). Chronic itch was reported by 36.9% of the patients and 4.7% of the healthy-skin controls. Itch was most frequent (occurrence rates higher than 80%) in patients with unclassified pruritus, prurigo and related conditions, atopic dermatitis and hand eczema. However, many patients with psychodermatological conditions and naevi also reported itch (occurrence rates higher than 19%).

Stigmatisation and body image impairment in dermatological patients: protocol for an observational multicentre study in 16 European countries.

INTRODUCTION: Patients with common skin diseases may have substantial psychosocial comorbidity and reduced quality of life. This study aims at exploring further the psychosocial burden of skin diseases by assessing stigmatisation and body image problems in a large sample of patients with skin disease across Europe. METHODS AND ANALYSIS: The study is an observational cross-sectional multicentre study across 16 European countries comparing stigmatisation and body image in patients with skin disease compared with controls. Consecutive patients will be recruited in outpatient clinics and will complete validated questionnaires prior to clinical examination by a dermatologist at each recruitment site. In addition to sociodemographic background information, the outcomes will be: mood disorders assessed by short versions of the Patient Health Questionnaire and the General Anxiety Disorder Assessment; general health assessed by the EuroQol-Visual Analogue Scale; stigmatisation experience assessed by the Perceived Stigmatisation Questionnaire; stress assessed by the Perceived Stress Scale and body image assessed by the Dysmorphic Concern Questionnaire. The main criteria for eligibility are to be 18 years old or more. The analysis will include comparison between patients and controls for the main outcomes using t-tests, analyses of covariance and multivariate logistic regression models adjusting for potential confounding factors. ETHICS AND DISSEMINATION: The study protocol is approved by the University of Giessen and by the local Ethical Committee in each recruitment centre. Informed consent will be given by each participant. The results of the study will be disseminated by publications in international peer-reviewed journals and presented at international conferences and general public conferences. Results will influence support intervention and management of patients with skin disease across Europe. TRIAL REGISTRATION NUMBER: DRKS00012745; Pre-results.

The Role of Therapy in Impairing Quality of Life in Dermatological Patients: A Multinational Study.

Skin disease and its therapy affect health-related quality of life (HRQoL). The aim of this study was to measure the burden caused by dermatological therapy in 3,846 patients from 13 European countries. Adult outpatients completed questionnaires, including the Dermatology Life Quality Index (DLQI), which has a therapy impact question. Therapy issues were reported by a majority of patients with atopic dermatitis (63.4%), psoriasis (60.7%), prurigo (54.4%), hidradenitis suppurativa (54.3%) and blistering conditions (53%). The largest reduction in HRQoL attributable to therapy, as a percentage of total DLQI, adjusted for confounders, was seen in blistering conditions (10.7%), allergic/drug reactions (10.2%), psoriasis (9.9%), vasculitis/immunological ulcers (8.8%), atopic dermatitis (8.7%), and venous leg ulcers (8.5%). In skin cancer, although it had less impact on HRQoL, the reduction due to therapy was 6.8%. Treatment for skin disease contributes considerably to reducing HRQoL: the burden of dermatological treatment should be considered when planning therapy and designing new dermatological therapies.

The psychosocial burden of hand eczema: Data from a European dermatological multicentre study.

BACKGROUND: The essential physical role, visibility and social importance of the hands place a major psychological burden on patients with hand eczema. OBJECTIVES: The aim of this study was to identify the psychological, social and clinical characteristics of patients with hand eczema, in particular the prevalences of depression, anxiety, suicidal ideation, and comorbidities. MATERIALS AND METHODS: Data on patients with hand eczema were analysed from a large European multicentre study conducted with dermatology outpatients from 13 countries. Groups of patients and controls were compared to analyse the psychological burden of hand eczema. RESULTS: Female patients with hand eczema had higher Hospital Anxiety and Depression Scale (HADS) scores for anxiety (n = 86, median = 7.0) than controls (n = 900, median = 5.0, P = .02), and for depression (median = 4.0) than controls (3.0, P < .001). Patients with high suicidal ideation, with low socioeconomic status and who were widowed or divorced were more likely to fulfil the HADS criteria for anxiety [odds ratio (OR) > 1, P = .038, P < .001, and P < .001, respectively]. The median Dermatology Life Quality Index score was 7.0 (n = 68). DISCUSSION: This study identifies a specific psychological burden experienced by hand eczema patients, highlighting the need for focused psychosocial interventions. Physicians in particular should be aware of the need to identify anxiety and depression in female patients.

Determinants of Psychosocial Health in Psoriatic Patients: A Multi-national Study.

There are limited data on the differences in the impact of psoriasis between various countries with respect to quality of life (QoL). The aim of this study was to explore the psychosocial health of patients with psoriasis in different European countries. A total of 682 patients were recruited in 13 European countries. All patients completed a questionnaire regarding socio-demographic information, negative life events, suicidal ideation and satisfaction with their dermatologist. Depression and anxiety were assessed with the Hospital Anxiety and Depression Scale (HADS), and QoL with the Dermatology Life Quality Index (DLQI) and EuroQoL (EQ-5D). The lowest anxiety and depression scoring was noted in patients from Denmark, the lowest level of impairment in QoL in subjects from Spain, and the highest level of impairment in QoL in patients from Italy. The most relevant parameters influencing patients' well-being were severity of pruritus and satisfaction with their dermatologist. The level of anxiety and depression symptoms correlated significantly with suicidal ideation.

The psychological burden of skin diseases: a cross-sectional multicenter study among dermatological out-patients in 13 European countries.

The contribution of psychological disorders to the burden of skin disease has been poorly explored, and this is a large-scale study to ascertain the association between depression, anxiety, and suicidal ideation with various dermatological diagnoses. This international multicenter observational cross-sectional study was conducted in 13 European countries. In each dermatology clinic, 250 consecutive adult out-patients were recruited to complete a questionnaire, reporting socio-demographic information, negative life events, and suicidal ideation; depression and anxiety were assessed with the Hospital Anxiety and Depression Scale. A clinical examination was performed. A control group was recruited among hospital employees. There were 4,994 participants--3,635 patients and 1,359 controls. Clinical depression was present in 10.1% patients (controls 4.3%, odds ratio (OR) 2.40 (1.67-3.47)). Clinical anxiety was present in 17.2% (controls 11.1%, OR 2.18 (1.68-2.82)). Suicidal ideation was reported by 12.7% of all patients (controls 8.3%, OR 1.94 (1.33-2.82)). For individual diagnoses, only patients with psoriasis had significant association with suicidal ideation. The association with depression and anxiety was highest for patients with psoriasis, atopic dermatitis, hand eczema, and leg ulcers. These results identify a major additional burden of skin disease and have important clinical implications.
