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.

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.

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.
