The contribution of perceptions of stigmatisation to disability in patients with psoriasis

Impact of residual skin lesions and previous biologic treatment failure on patient-reported outcomes in patients with psoriasis receiving biologic treatment

Recent advances in biologic treatments have made clear skin a realistic treatment goal for psoriasis. However, clear skin may not uniformly translate to an absence of impact on patients' quality of life. This retrospective observational study aimed to elucidate the factors influencing patient-reported outcomes in patients with psoriasis who have demonstrated successful clinician-reported outcomes on using biologics. A total of 96 patients who have achieved a ≥75% improvement in Psoriasis Area and Severity Index (PASI) scores with ≥6 months of biologic treatment were included. Their median PASI score was 0.4, with 37.5% having achieved PASI 100 (clear skin). Furthermore, 47.9% reported no impact of psoriasis on their quality of life (Dermatology Life Quality Index [DLQI] score 0 or 1), while 52.1% reported a negative impact (DLQI score ≥2). Notably, 28.1% of the participants had a history of biologic treatment failure, defined as the inability to achieve or sustain a 75% PASI improvement with the previously used biologic agent. Multivariable logistic regression analysis revealed a positive association between achieving PASI 100 and reporting no impact of psoriasis on quality of life (adjusted odds ratio [aOR] 3.88, 95% confidence interval [CI] 1.49-10.91, P = 0.007). Conversely, prior biologic treatment failure was negatively associated with reporting no impact of psoriasis on quality of life (aOR 0.13, 95% CI 0.02-0.65, P = 0.023). Furthermore, among patients with clear skin, those with experience of previous biologic treatment failure reported significantly lower quality of life than those without such experience (P = 0.033). In conclusion, minimal residual skin lesions and prior biologic treatment failure were associated with poorer patient-reported outcomes in patients with psoriasis. Opting for a biologic agent with the highest predicted efficacy, rather than pursuing a "step-up" approach with a higher possibility of treatment failure, may be a more suitable strategy in the biologic treatment of psoriasis.

A comprehensive overview of psoriatic research over the past 20 years: machine learning-based bibliometric analysis

Background

The surge in the number of publications on psoriasis has posed significant challenges for researchers in effectively managing the vast amount of information. However, due to the lack of tools to process metadata, no comprehensive bibliometric analysis has been conducted.

Objectives

This study is to evaluate the trends and current hotspots of psoriatic research from a macroscopic perspective through a bibliometric analysis assisted by machine learning based semantic analysis.

Methods

Publications indexed under the Medical Subject Headings (MeSH) term "Psoriasis" from 2003 to 2022 were extracted from PubMed. The generative statistical algorithm latent Dirichlet allocation (LDA) was applied to identify specific topics and trends based on abstracts. The unsupervised Louvain algorithm was used to establish a network identifying relationships between topics.

Results

A total of 28,178 publications were identified. The publications were derived from 176 countries, with United States, China, and Italy being the top three countries. For the term "psoriasis", 9,183 MeSH terms appeared 337,545 times. Among them, MeSH term "Severity of illness index", "Treatment outcome", "Dermatologic agents" occur most frequently. A total of 21,928 publications were included in LDA algorithm, which identified three main areas and 50 branched topics, with "Molecular pathogenesis", "Clinical trials", and "Skin inflammation" being the most increased topics. LDA networks identified "Skin inflammation" was tightly associated with "Molecular pathogenesis" and "Biological agents". "Nail psoriasis" and "Epidemiological study" have presented as new research hotspots, and attention on topics of comorbidities, including "Cardiovascular comorbidities", "Psoriatic arthritis", "Obesity" and "Psychological disorders" have increased gradually.

Conclusions

Research on psoriasis is flourishing, with molecular pathogenesis, skin inflammation, and clinical trials being the current hotspots. The strong association between skin inflammation and biologic agents indicated the effective translation between basic research and clinical application in psoriasis. Besides, nail psoriasis, epidemiological study and comorbidities of psoriasis also draw increased attention.

Stigmatization among Patients with Plaque Psoriasis

The aim of the study was to analyze the level of stigmatization among patients with plaque psoriasis according to their demographic and clinical characteristics. The study included 122 patients who completed the 6-item and 33-item Feelings of Stigmatization Questionnaire and a sociodemographic survey. The analysis of the 6-item Stigmatization Scale showed a mean stigmatization score of 6.4 points. (Me = 6; s = 3.7); the mean score for the 33-item scale was 81.3 points (Me = 79.5; s = 19.9). Female patients felt stigmatized more often than males. Respondents living in the countryside had a stronger sense of stigmatization in the Sensitivity to Others' Attitudes (p = 0.0238) and Secretiveness (p = 0.0234) domains. The presence of psoriatic lesions across the entire body was the only explanatory variable significantly determining the level of stigmatization in the Positive Attitudes domain, either through the main effect or through the interaction with the patient sex. A highly significant difference was found for the feeling of being flawed domain (p = 0.044), with a mean score of 13.4 points. The issue of stigmatization in psoriasis deserves more attention, as the analysis of this problem may provide a better insight into the effect of the disease on the patient's condition, not merely in the context of its clinical manifestation.

The Extent of Misconceptions, Negative Prejudices, and Discriminatory Behaviors Toward Psoriasis Patients: A Cross-Sectional Survey Study Among the Population of Jeddah, Saudi Arabia

Background Psoriasis is a chronic inflammatory disease that affects around 2% of the population. The lives of psoriasis patients are greatly impacted by stigma and social exclusion, regardless of the severity of the condition. This is the first study of its kind to be conducted in Saudi Arabia. This study aimed to assess peoples' psoriasis-related misconceptions, negative prejudice, and discriminatory behaviors. Methodology A self-administered Google Forms survey was distributed between January and February 2023. The survey was conducted among residents of Jeddah, Saudi Arabia who were enrolled randomly via social media. We aimed to investigate their perception and awareness related to psoriasis, as well as how varying educational levels, age groups, and genders affected these variables. Results In total, 803 individuals participated in the survey. Results showed that 19.9% of the participants did not know about psoriasis. Only 5.1% of respondents stated that they were well knowledgeable about psoriasis. Moreover, psoriasis was more frequently perceived as a communicable disease by people in the age group of 18-29 years (p = 0.000). Surprisingly, only 43.5% of the participants reported that they would shake hands with someone with psoriasis without hesitation. Additionally, 40.7% of the participants were aware that psoriasis requires lifelong treatment. Moreover, the belief that psoriasis does not require lifelong therapy was more prevalent among university graduates (p = 0.000). Conclusions This study found that the residents of Jeddah need further education on skin disorders, in general, and psoriasis, in particular. Future studies should be conducted utilizing various approaches, with a greater emphasis on certain groups of people who engage physically with psoriasis patients.

Investigating the Role of Upward Comparisons and Self-compassion on Stigma in People With Acne: Cross-sectional Study

BACKGROUND

The use of image-laden social media is hypothesized as being implicated in psychological distress in individuals with conditions affecting their appearance. However, relatively little is known about the mechanisms involved in this relationship.

OBJECTIVE

This cross-sectional study examined the relationship between photo-orientated social media use and feelings of stigmatization in adults with acne, and tested whether upward skin comparisons mediate and self-compassion moderates this relationship.

METHODS

Adults (N=650) with acne symptoms completed web-based measures of social media use (daily Facebook or Instagram use, Facebook function use), self-compassion, skin appearance comparisons, and internalized stigmatization.

RESULTS

Moderated-mediation and mediation analyses indicated that there was a significant indirect effect of Facebook photo use on stigmatization, mediated by upward appearance comparisons (estimation of indirect effect 11.03, SE 5.11, 95% CI 1.19-21.12). There was no significant relationship between Instagram use and feelings of stigmatization (estimation of indirect effect 0.0002, SE 0.005, 95% CI -0.011 to 0.009), yet upward appearance comparisons predicted feelings of stigmatization (B=0.99, P<.001). Self-compassion did not moderate the indirect or direct relationships between photo-orientated social media use and stigma. However, self-compassion was negatively correlated with upward appearance comparisons and feelings of stigmatization in both Facebook and Instagram users.

CONCLUSIONS

The way that individuals engage with social media, and in particular make appearance comparisons, should be considered when working with individuals with skin-related distress. Interventions aimed at boosting self-compassion and reducing appearance comparisons may provide avenues for protecting against feelings of stigma.

Experiences and coping behaviours of patients with psoriasis: a qualitative study

BACKGROUND

Psoriasis is a complex, chronic, lifelong inflammatory skin disease characterized by the development of erythematous, indurated, scaly, pruritic and often painful skin plaques, and it is currently incurable. It profoundly affects psychological wellbeing and social functioning and has significant associated co-morbidities. To improve clinical approaches, understanding of the experiences of patients with psoriasis is needed.

OBJECTIVE

To explore the experiences and coping behaviours of patients with psoriasis.

METHODS

A qualitative study approach was conducted. Through semi-structured interviews, 20 patients with psoriasis were recruited from general practices and specialist dermatology practices in a regional teaching hospital in Taiwan. Recorded interviews were transcribed and analysed by content analysis.

RESULTS

Three themes and nine subthemes were identified: 1. Symptoms distress: (a) trouble with scaling, (b) bothersome itching, and (c) complex pain experiences; 2. Psychological distress: (a) encountering discrimination and (b) feeling stigmatised; 3. Managing psoriasis: (a) coping with symptoms, (b) seeking alternative methods, (c) using biologic agents, and (d) changing thinking and coexisting with the disease.

CONCLUSION

The experience of patients with psoriasis has significant negative impacts on their lives. The findings of this study can provide healthcare professionals with a reference for the care of patients with psoriasis.

Prevalence and Odds of Anxiety Disorders and Anxiety Symptoms in Children and Adults with Psoriasis: Systematic Review and Meta-analysi

The magnitude of the association between psoriasis and depression has been evaluated, but not that between psoriasis and anxiety. The aim of this systematic review and meta-analysis was to examine the prevalence and odds of anxiety disorders and symptoms in patients with psoriasis. Five medical databases (Cochrane Database, EMBASE, PubMed, PsychINFO, ScienceDirect) were searched for relevant literature. A total of 101 eligible articles were identified. Meta-analysis revealed different prevalence rates depending on the type of anxiety disorder: 15% [95% confidence interval [CI] 9–21] for social anxiety disorder, 11% [9–14] for generalized anxiety disorder, and 9% [95% CI 8–10] for unspecified anxiety disorder. There were insufficient studies assessing other anxiety disorders to be able to draw any conclusions on their true prevalence. Meta-analysis also showed a high prevalence of anxiety symptoms (34% [95% CI 32–37]). Case-control studies showed a positive association between psoriasis and unspecified anxiety disorder (odds ratio 1.48 [1.18; 1.85]) and between psoriasis and anxiety symptoms (odds ratio 2.51 [2.02; 3.12]). All meta-analyses revealed an important heterogeneity, which could be explained in each case by methodological factors. The results of this study raise the necessity of screening for the presence of anxiety disorders, as previously recommended for depressive disorders, in patients with psoriasis and, if necessary, to refer such patients for evaluation by a mental health professional and appropriate treatment.

The Burden of Living With Cutaneous Lupus Erythematosus

Cutaneous lupus erythematosus (CLE) is a group of heterogeneous autoimmune disorders primarily affecting the skin. Patients with these conditions are mostly young women when they become sick and often suffer from recurrent skin symptoms or longstanding changes in their physical appearance. CLE disorders lead to different levels of morbidity and can impact profoundly patients' quality of life, particularly in the psychological and social health domains. This review provides a summary of recent research investigating the psychosocial burden of living with CLE and the intersect amongst the disease characteristics, patient factors, and social determinants of health. Furthermore, this review provides insight into patient care and research needs that remain unmet to improve the quality of life of patients living with CLE.

Depression, stigma and social isolation: the psychosocial trifecta of primary chronic cutaneous lupus erythematosus, a cross-sectional and path analysis

Objective

Depression is common in individuals with chronic cutaneous lupus erythematosus (CCLE). However, how CCLE may impact patients’ psychological well-being is poorly understood, particularly among disproportionally affected populations. We examined the relationships between depression and psychosocial factors in a cohort of predominantly Black patients with primary CCLE (CCLE without systemic manifestations).

Methods

Cross-sectional assessment of individuals with dermatologist-validated diagnosis of primary CCLE. NIH-PROMIS short-forms were used to measure depression, disease-related stigma, social isolation and emotional support. Linear regression analyses (ɑ=0.05) were used to test an a priori conceptual model of the relationship between stigma and depression and the effect of social isolation and emotional support on that association.

Results

Among 121 participants (87.6% women; 85.1% Black), 37 (30.6%) reported moderate to severe depression. Distributions of examined variables divided equally among those which did (eg, work status, stigma (more), social isolation (more), emotional support (less)) and did not (eg, age, sex, race, marital status) significantly differ by depression. Stigma was significantly associated with depression (b=0.77; 95% CI0.65 to 0.90), whereas social isolation was associated with both stigma (b=0.85; 95% CI 0.72 to 0.97) and depression (b=0.70; 95% CI0.58 to 0.92). After controlling for confounders, stigma remained associated with depression (b=0.44; 95% CI0.23 to 0.66) but lost significance (b=0.12; 95% CI −0.14 to 0.39) when social isolation (b=0.40; 95% CI 0.19 to 0.62) was added to the model. Social isolation explained 72% of the total effect of stigma on depression. Emotional support was inversely associated with depression in the univariate analysis; however, no buffer effect was found when it was added to the multivariate model.

Conclusion

Our findings emphasise the psychosocial challenges faced by individuals living with primary CCLE. The path analysis suggests that stigmatisation and social isolation might lead to depressive symptoms. Early clinical identification of social isolation and public education demystifying CCLE could help reduce depression in patients with CCLE.

Serum interleukin-23 levels: relation to depression, anxiety, and disease activity in psoriatic arthritis patients

Objectives

Assessment of serum levels of IL-23 in PsA patients and its correlation with depression, anxiety, and disease activity.

Methods

Eighty psoriatic arthritis (PsA) patients and eighty healthy volunteers matched for age and gender were included in this observational case–control study. All participants suspected to detailed history, clinical assessment, PsA activity using Disease Activity Index for Psoriatic Arthritis (DAPSA) score, the severity and extent of psoriasis was assessed by the Psoriasis Area and Severity Index (PASI), and ultrasonographic assessments of the entheses were examined according to the Madrid Sonographic Enthesitis Index (MASEI). Depression and anxiety were assessed by Hospital Anxiety and Depression Scale (HADS). Serum IL-23 was measured and correlated with disease activity, depression, and anxiety.

Results

There was no significant difference between patients and controls regarding demographic data. Thirty-six PsA patients (45%) had anxiety and 28 patients (35%) had depression, while in the control group, 16 persons (20%) had anxiety and 12 (15%) had depression, with significant differences between the 2 groups (p < 0.0001). There were significant differences in HADS anxiety and depression scores between patients and controls with significant positive correlations between HADS depression, anxiety scores and IL-23, DAPSA, PASI, and MASEI scores (p < 0.05). IL-23 was positively correlated with DAPSA, PASI, and HADS scores; we observed that interleukin 23, higher DAPSA, and PASI were independently associated with depression and anxiety.

Conclusion

Serum interleukin-23 levels were elevated in PsA patients and were found to be correlated with depression, anxiety, and disease activity.

Key Points • Psoriatic arthritis is a multidimensional disorder with psychiatric drawbacks. • Interleukin-23 is a proinflammatory cytokines that was correlated with depression and anxiety in PsA patients. • Interleukin-23 was correlated with disease activity in PsA. • Depression and anxiety were positively correlated with disease activity in PsA.

Update on the Management of Pediatric Psoriasis: An Italian Consensus

Introduction

Psoriasis affects children with a considerable burden in early life. Treating pediatric psoriasis is challenging also because of the lack of updated specific guidelines. With the recent approval of several biologics for pediatric psoriasis and the ongoing COVID-19 pandemic, the management of young psoriatic patients is facing major changes. A revision of treatment recommendations is therefore needed.

Methods

In September 2021, a board of six Italian dermatologists convened to update treatment recommendations. The board issued evidence- and consensus-based statements covering relevant areas of pediatric psoriasis, namely: assessment of psoriasis severity, management of children with psoriasis, and treatment of pediatric psoriasis. To reach consensus, the statements were submitted to a panel of 24 experts in a Delphi process performed entirely via videoconference. A treatment algorithm was produced.

Results

There was full consensus that psoriasis severity is determined by the extension/severity of skin lesions, site of lesions, and impact on patient quality of life. Agreement was reached on the need for a multidisciplinary approach to pediatric psoriasis and the importance of patient/parents education. The relevance of vaccinations, including COVID-19 vaccination, for psoriatic children was acknowledged by all participants. Management issues that initially failed to reach consensus included the screening for psoriasis comorbidities and early treatment with biologics to prevent them and the use of telemedicine to facilitate patient follow-up. There was full consensus that topical corticosteroids are the first choice for the treatment of mild pediatric psoriasis, while phototherapy and systemic therapy are used in children with moderate-severe psoriasis. According to the proposed treatment algorithm, biologics are the first line of systemic therapy.

Conclusions

Targeted systemic therapies are changing the treatment of moderate-severe pediatric psoriasis, while topical corticosteroids continue to be the first choice for mild disease. Children-centered research is needed to further improve the treatment of pediatric psoriasis.

Effect of CoQ10 Administration to Psoriatic Iraqi Patients on Biological Therapy Upon Severity Index (PASI) and Quality of Life Index (DLQI) Before and After Therapy

Psoriasis is a medical condition in which the skin of the body is affected at a multisytemic level. Patients with moderate to severe psoriasis have a considerably reduced quality of life as a result of their disease. For morphological indicators, the Psoriasis Area Severity Index (PASI) test is one of the methods for indicating the severity of the illness. An imbalance between pro-oxidants and antioxidants in our bodies causes oxidative stress and plays a crucial role in the pathophysiology of chronic inflammatory diseases like psoriasis(1). It has been considered that antioxidant treatment can be an effective therapeutic option. The goal of this clinical investigation was to see if there was a link between the percentage change in quality of life and the clinical severity of psoriasis during a 12-week period among Iraqi psoriatic patients. Over the course of 3 months, 24 psoriatic patients (9 females and 15 males) ranging in age from 17 to 72 years participated in a prospective double-blinded clinical experiment. Two groups of participants were formed. A biological medicine (adalimumab) and a placebo was given to group A (n = 11), whereas group B (n = 13) received 100 mg CoQ10 adjuvant therapy in addition to the biological medication already provided. The Psoriasis Area and Severity Index (PASI) and the Dermatology Life Quality Index (DLQI) were used to examine patients (DLQI). Treatment with both biological and adjuvant CoQ10 therapy showed a substantial association between the PASI and the DLQI (p = 0.000132). After 3 months of therapy, the mean (SD) of the PASI score for all patients was 20.88 7.15, with a 67.48% ± 22.25% improvement change. The mean SD of the DLQI score at baseline was 12.5 ± 4.71, with a change of 56.13% ± 20.15% following treatment. After therapy with a biological medication, there was a favorable association between the PASI and the DLQI (p > 0.05). This indicates that therapy with a biological medication with daily administration of 100 mg CoQ10 supplements to psoriatic patients for 12 weeks improved the correlation between PASI and DLQI.

A digital therapeutic for management of psychosocial aspects of psoriasis: A pre‐post proof of concept study

Background

Despite the psychosocial challenges of living with psoriasis many patients may not be able to access appropriate services to manage these challenges. Mobile health interventions may be helpful as a means to support patients in managing the impact of their condition.

Objective

To conduct a preliminary examination of the feasibility and acceptability of a bespoke psoriasis‐specific digital therapeutic solution (hereafter termed Allay), and to provide initial data on psychological changes pre‐post.

Methods

Phase one proof of concept pre‐post study. Eligible patients were provided with Allay on their smartphone and assessed at baseline and at 12 weeks on a range of indices of well‐being. Participants experiences on usability were collected by telephone interview at 4 weeks, 8 and 12 weeks.

Results

Out of 66 participants recruited, 59 persisted in using Allay after the familiarisation phase, and 34 participants completed the 12 weeks programme. Participants showed a statistically significant improvement between induction and the end of the 12 weeks programme on Quality of life, Resilience, Perceptions of ‘Overall impact’ of psoriasis, and ‘Emotional impact’. There was a significant change over the course of using Allay for symptoms of depression but not anxiety. While there was an interaction effect of changes in severity of psoriasis symptoms over the course of the study for dermatology‐specific measures, there was no interaction between such changes in psoriasis symptoms and changes in depression, resilience or beliefs in emotional impact.

Conclusions

Study results suggest that the use of Allay as an adjunct to medical management of psoriasis may help patients improve resilience, mood, beliefs about their condition and enhance their quality of life. Given that this is a phase one proof of concept study, and our rates of attrition further research is necessary to examine comparative effectiveness and stability of these findings.

A Multivariate Analysis of Depression Prevalence in Psoriasis Patients: A Cohort Study

The literature reported higher depression rates in psoriasis patients compared to the general population. Our study aimed to verify whether variability in depression prevalence was due to using different diagnostic tools. We also aimed to determine whether dysfunctional coping strategies might increase the depression burden. We assessed psoriasis severity by the Psoriasis Area Severity Index (PASI) and PSOdisk. We analyzed mental alterations of 120 outpatients by Hamilton Depression and Anxiety Rating Scales (HAM-D and HAM-A), Symptom Checklist-90-Revised (SCL-90-R), plus coping strategies and quality of life by Coping Orientation to Problems Experienced (COPE) Inventory and 36-Item Short Form Health Survey (SF-36). We divided our cohort into five subgroups from minimal to severe psoriasis using the PSOdisk total score. Depression prevalence varied according to the assessment criteria for specificity, frequency, and severity. Different mood disorders other than major depression emerged when we used DSM-IV-TR criteria. Correlation analysis of the criteria we used to diagnose depression or depressed mood indicated that a dysfunctional coping strategy was highly and positively correlated only in patients of the severe subgroup. Differently, a negative correlation emerged between the SF-36 Mental Summary Component (MSC) and behavioral disengagement, thus suggesting that psychopathological distress might induce patients with a marked/severe psoriasis to adopt dysfunctional coping strategies. Dermatologists are fundamental in detecting comorbid depression, referring psoriasis patients to mental health specialists to achieve adequate treatments, and preventing suicide risk.

A Randomised Controlled Feasibility Trial of Online Compassion-focused Self-Help for Psoriasis

BACKGROUND

People with psoriasis can experience psychological distress that might be amenable to psychosocial self-help.

OBJECTIVES

This study tested the feasibility and acceptability of two theoretically developed self-help interventions designed to reduce feelings of shame and improve quality of life.

METHODS

A randomised controlled feasibility trial was conducted with one hundred and thirty participants with psoriasis who were randomly allocated to receive either compassion-based self-help (n =65) or mindfulness-based self-help (n =65), over a four-week period.

RESULTS

The interventions were found to be acceptable with over 70% of study completers reported finding the materials helpful. Ninety-two participants completed the study with attrition at 30%. Both interventions showed modest yet statistically significant reductions in shame (d = .20) and improvements in quality of life (d = .40).

CONCLUSIONS

Self-help based on compassion and mindfulness is acceptable to users and can reduce feelings of shame and improve quality of life for people living with psoriasis.

Real-world effectiveness of guselkumab in patients with psoriasis: Health-related quality of life and efficacy data from the noninterventional, prospective, German multicenter PERSIST trial

Psoriasis is a common, chronic inflammatory skin disorder negatively impacting health-related quality of life (HRQoL). Guselkumab, targeting interleukin-23 (IL-23), is an approved biologic therapy for psoriasis. PERSIST is an ongoing prospective, noninterventional, long-term, German multicenter study evaluating the effect of guselkumab on HRQoL, and its efficacy and safety in patients with moderate-to-severe psoriasis in a real-world setting. The primary endpoint is the proportion of patients with a Dermatology Life Quality Index (DLQI) score ≤ 1 at week 28. Of 303 patients enrolled and treated with guselkumab, mean age and disease duration were 49.7 and 21.0 years, respectively, and 51.2% (n = 155) of patients had received ≥1 prior biologic therapy. Mean baseline DLQI score was 13.7, and mean symptom and sign scores in the Psoriasis Symptoms and Signs Diary (PSSD) were 51.9 and 60.8, respectively. Baseline Psoriasis Area Severity Index (PASI) and body surface area (%) scores were 16.4 and 27.5. Following 28 weeks of guselkumab treatment, the mean DLQI score decreased to 2.8, and 56.8% of patients (n = 150) achieved DLQI ≤ 1. Mean PSSD symptom and sign scores also improved, decreasing to 12.5 and 15.9, respectively. At week 28, PASI 90 response was 55.3%; significant improvement was observed in patients with psoriasis in difficult-to-treat areas. Overall, analyses demonstrated that guselkumab was effective in the real-world setting, as measured by HRQoL and skin improvements, even in patients with a high burden of disease and those who have received multiple biologic therapies. No new safety signals were observed.

Examining Individual Differences in Wellbeing, Anxiety and Depression in Psoriasis Using a Clinically Modified Buddhist Psychological Model

Psoriasis patients can experience a range of psychosocial difficulties, which can lead to issues with wellbeing, anxiety and depression. Mindfulness-based interventions have positive impacts on these outcomes; however, there is a need to identify the mechanisms of action of such interventions. This study attempts to do so by examining individual differences in psoriasis patients' wellbeing, anxiety and depression using a clinically modified Buddhist psychological model (CBPM). Psoriasis patients (N = 285) and (N = 209) completed measures of each CBPM component at time 1 and 2. SEM analyses found that a direct and mediated effect of CBPM model was a good fit to the participant's data. This study suggests that non-attachment, aversion, acceptance and self-compassion could have a direct effect on the wellbeing, anxiety and depression of psoriasis patients and an indirect effect through reduced worry and rumination. This study provided preliminary evidence for the CBPM as being a useful explanatory framework of psoriasis patients' anxiety, depression and wellbeing.

Internalized Stigma and Psychiatric Morbidity among Patients with Psoriasis: A Study from North India

Background

Psoriasis is a chronic inflammatory dermatosis associated with psychological morbidity. Like mental illness, it is also associated with stigma. Very few studies from India have evaluated stigma experienced by patients with psoriasis.

Aim of the Study

To study stigma in patients with psoriasis (in the form of internalized stigma, perceived stigma, and social-participation-restriction stigma) and its relationship with demographic and clinical variables.

Methodology

104 patients with psoriasis assessed on the internalized stigma of mental illness scale (ISMIS), explanatory model interview catalogue stigma scale, participation scale (P-scale), perceived social support, total score of Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder (GAD-7) scale, Dermatology Life Quality Index, and Psoriasis disability index.

Results

On ISMIS, overall, 27.9% had experienced stigma. On domains, majority of the participants experienced discrimination (52.9%) followed by stigma resistance (51.9%), stereotype (26.0%), social withdrawal (24.1%), and alienation (23.1%). Majority of them reported mild restriction. As per the evaluation by a qualified psychiatrist, about 30% of the participants had at least one psychiatric diagnosis. On comparison, those with the presence of co-morbid psychiatric illness experienced a higher level of stigma on each domain of ISMIS except discrimination and stigma resistance. Lower social support was associated with higher stigma in all the domains. All the domains of ISMIS except discrimination and stigma resistance were associated with a higher level of anxiety and depression, poor quality of life, and higher disability.

Conclusion

The patients with psoriasis experience a significant amount of stigma and stigma is associated with the presence of psychiatric morbidity, lower social support, higher restriction, and more disability.

Validation of psoriasis disability index (PDI) questionnaire Sinhala version

INTRODUCTION/OBJECTIVES

Psoriasis is a chronic inflammatory dermatosis with significant physical and psychological impact leading to negative influence on the quality of life among patients with psoriasis. Other than the disease characteristics many external factors could operate in South Asian context. Lack of a reliable disease-specific instrument prevents objective estimation and monitoring of disability in patients with psoriasis and hence we aim to validate assess the psychometric properties of the Sinhala version of PDI.

METHODS

A cross-sectional study conducted at dermatology clinic at a tertiary care National Hospital in Sri Lanka. Patients with psoriasis and on therapy at least 4 weeks prior to enrollment, aged more than 18 years, were included while those with already diagnosed psoriatic arthritis and/or nail psoriasis alone without any skin involvement and generalized pustular psoriasis de novo were excluded. All patients were examined by dermatologist to obtain disease characteristics. The reliability was assessed by internal consistency using Cronbach's α and item-total correlation. Convergent validity was measured with the known groups.

RESULTS

Of 199 patients studied, the PDI Sinhala version showed Cronbach's α of 0.86 (all 15 items) and ranged from 0.57 to 0.77 for subscales. PDI score and Dermatology Life Quality Index (DLQI) showed good correlation of coefficient 0.76 (p < 0.01). Positive associations were noted with extent and severity of psoriasis when using sample medians (p < 0.05). The dimensionality of the PDI was determined using exploratory factor analysis and four factors were structured.

CONCLUSION

The PDI Sinhala version is proved to be valid and reliable tool to assess the burden of psoriasis among Sinhala conversant patients in Sri Lanka.

Stigma in visible skin diseases - a literature review and development of a conceptual model

The burden of visible skin diseases (VSDs) includes not only physical symptoms but also psychosocial consequences such as depression, anxiety, impaired quality of life and low self-esteem. Stigmatization was shown to play a major role in people with skin diseases. The aim of the study was to review the evidence for the components, drivers and impacts of (self-)stigma, and to organize the data into a series of conceptual models. A targeted literature search was conducted to identify studies on (self-)stigma in relation to VSD. Conceptual models of stigma in VSDs were developed from existing generic conceptual models for VSD and of generic conceptual models of stigma and were refined after discussion with a board of experts, patient advocacy groups, clinicians and researchers. A total of 580 references were identified, of which 56 references were analysed and summarized. Two conceptual models of stigma were identified: one with external stigma and self-stigma dimensions, the other for self-stigma in mental health. These models were adapted to allow a complete description of stigma in VSDs. For this, a distinction was made between 'discrimination' and 'impact'. Finally, five models were developed: macro-overview; stigma, impact and socio-demographics; stigma, impact and disease characteristics; stigma, impact and quality of life; and stigma, impact and coping. Gaps were identified in available quantitative evidence. To our knowledge, this is the first conceptual model of stigma in VSDs. The model will help to standardize evaluation of stigma and to enhance empirical evaluation of anti-stigma interventions in VSDs. Further research should be conducted to develop a more complete model in stigma due to significant gaps in existing evidence, particularly including the stigma in others (external stigma) and also to cover a broader range of VSDs as their impact on particular dimensions of stigma differs.

The Temperament Risk Factor, Disease Severity, and Quality of Life in Patients with Psoriasis

Background

Psoriasis exerts a profound negative impact on health-related quality of life (QoL). Although the severity of psoriasis is one potential variable that contributes to decreased QoL, previous studies have shown only weak or no association between measures of psoriasis severity and QoL. We hypothesized that this relationship is moderated by temperament factors.

Objective

We aimed to verify whether the relationship between disease severity and QoL is moderated by a constellation of temperament traits (i.e., temperament risk factors) and whether this moderation takes place via cognitive-appraisal and coping processes.

Methods

One hundred fifty patients with psoriasis vulgaris participated in the study. Psoriasis severity was assessed by a standardized measure, the Psoriasis Area and Severity Index (PASI), and the patients also completed a battery of psychological questionnaires assessing QoL, temperament, disease-related cognitive appraisals, and coping strategies.

Results

A specific constellation of temperament traits was found to moderate the strength of the association between the PASI and QoL. This constellation of temperament traits was associated with certain disease-related cognitive appraisals (i.e., threat, obstacle/loss, harm, profit, value) and emotion-focused coping strategies (i.e., self-blame, avoidance, resignation, seeking social support, and seeking information).

Conclusion

The constellation of temperament traits is a crucial individual variable that strongly moderates the negative impact of psoriasis severity on QoL, potentially through the activation of non-adaptive cognitive appraisals and coping strategies in susceptible individuals.

Social awareness about psoriasis: Misconceptions, negative prejudices and discriminatory behavior

Psoriasis patients experience negative attitudes and behaviors exhibited by people who have insufficient knowledge about psoriasis. In this study, the knowledge level of the society about psoriasis; people's attitudes toward such patients were investigated. A questionnaire that investigates the knowledge, attitudes, and behaviors related to psoriasis according to age, gender, and education levels was applied to the participants. About a quarter of participants in the study did not have any knowledge about psoriasis, 22.9% participants who thought that they knew about psoriasis believed that psoriasis was an infectious disease, 34.2% indicated that they were afraid of shaking hands with patients who had psoriasis, 45.4% did not wish to eat any food prepared by such patients, and 13.4% did not want to work with them in the same workplace. Female participants were more concerned that psoriasis was contagious (P = .030) than male participants, and they were more concerned about shaking hands (P = .022) and eating food prepared by psoriasis patients (P = .009). Both the psoriasis is little known and the level of knowledge of the participants who think they have knowledge about psoriasis was insufficient and prejudiced attitudes and behaviors are common in patients with psoriasis.

Anticipated and Perceived Stigma Among Patients With Psoriasis

BACKGROUND

Perceived stigma among patients with psoriasis (PWP) is associated with poorer quality of life.

OBJECTIVE

To determine the prevalence and predictors of stigmatizing attitudes that PWP expect and experience from others.

METHODS

We conducted a survey using validated outcome measures to assess the extent to which PWP anticipate and perceive stigma from others. Demographic and clinical characteristics were obtained from electronic medical records.

RESULTS

Patients (n = 106) were 48.11% female, 70.75% white, and had a mean age ± SD of 47.90 ± 16.19 years old. Of all, 25.47% self-reported their psoriasis as severe. Mean physician global assessment score ± SD was 2.98 ± 1.81. Two-thirds (66.98%) of patients reported that, in response to seeing their psoriasis-affected skin, they anticipated others to stereotype them as "contagious." Linear regression analyses demonstrated that patient-reported severe psoriasis, compared to mild psoriasis, was associated with greater anticipation of negative stereotypes, social avoidance, and perceived stigma from others (P values < .05). Physician-measured body surface area and global assessment scores were not significantly associated with any outcome.

CONCLUSION

Prevalence of anticipated and perceived stigma among PWP is high. Our results suggest that objective measures of severity may not identify patients at risk of stigma-related distress. Additional methods, such as directly inquiring about stigmatizing experiences, may be needed.

Emotions, Alexithymia, and Emotion Regulation in Patients With Psoriasis

Psoriasis is a chronic dermatological condition that is frequently associated with problematic patterns of emotional reactivity (the way in which patients react to stimuli), alexithymia (their ability to recognize and label the emotional reaction), and emotion regulation (the ability to enhance or reduce their own emotional reaction). A research in the peer-reviewed scientific literature was conducted in order to identify articles describing the association of psoriasis and affective problems. In particular, we first evaluate studies that have investigated abnormal emotional reactivity (in terms of duration, frequency, or type of the experienced emotions) and its impact on patients' quality of life; next, we review the role of alexithymia and emotion regulation in modulating the relationship between emotional reactivity and quality of life in this population. From a critical analysis of the reviewed studies, we highlight that altered emotional processing might be particularly important in the characterization of this condition. In particular, we show that this condition is related to an emotional reactivity characterized by negative emotions that have a stronger impact on patients' quality of life when emotion regulation abilities are weak, especially if patients have alexithymia. Finally, we present suggestions for future directions in both clinical and research fields.

Psychological Distress, Alexithymia and Alcohol Misuse in Patients with Psoriasis: A Cross-Sectional Study

This study investigates (a) the prevalence of psychological distress, alexithymia and alcohol misuse in psoriasis patients; and (b) the relationship between psoriasis severity, alexithymia, alcohol and psychological distress in patients with psoriasis. A cross-sectional study was conducted. Outpatients (n = 184) with moderate to severe psoriasis completed a psychological screening battery. Measures included the Hospital Anxiety and Depression Scale, the Penn State Worry Questionnaire, the twenty-item Toronto Alexithymia Scale, the Dermatology Life Quality Index, the Psoriasis Area and Severity Index, the Self-Administered Psoriasis Area and Severity Index, and the Alcohol Use Disorders Identification Test. Demographic, clinical details and information on knowledge of psychosocial issues, alcohol and confidence on coping with distress and talking to others about psoriasis was also gathered. Alexithymia was associated with anxiety, depression and worry; subjective psoriasis severity was associated with worry. Alcohol misuse was related to anxiety and worry, but not to depression. Appropriate identification and treatment of alcohol difficulties and psychological distress of patients with psoriasis is needed.

Perception and determinants of stigmatization of people with psoriasis in the German population

BACKGROUND

Perception of psoriasis in the general population is characterized by knowledge deficits and prejudice against those affected. The extent and possible predictors of stigmatizing attitudes remain unclear.

OBJECTIVES

The aim was to assess prejudices and stigmatization of people with psoriasis and to identify sociodemographic and attitude-related variables accounting for stigmatization.

METHODS

Representative telephone surveys of 2004 (in 2017) and 2001 (in 2018) adults using a standardized questionnaire. Descriptive analyses were applied to living area, age, gender, educational status, general knowledge and attitudes about psoriasis. Logistic regression analyses were carried out to determine which variables are associated with the assessment of prejudices of 'others' against people with psoriasis. Those prejudices were specified by the following statements: 'they should take better care of themselves', 'don't want to touch people with psoriasis' and 'disgusted by psoriasis'.

RESULTS

The majority of those surveyed (74%) believe that people with psoriasis are disadvantaged. Similarly, a majority (69%) said that most people find psoriasis disgusting, do not want to touch people with psoriasis (59%) and think that people with psoriasis need to take better care of themselves (45%). 'Willing to enter a relationship with an affected person' (OR = 0.330, P = 0.029), higher age (OR = 1.027, P <0.001) and male gender (OR = 1.263, P = 0.034) proved to be significantly associated with 'psoriasis is disgusting'. Education (OR = 1.648, P = 0.016) and lower age (OR = 0.847, P  <0.001) are significantly associated with 'they need to take better care of themselves'.

CONCLUSIONS

Data suggest that stigmatization of skin diseases is still entrenched. This overview shows the need for interventions against stigmatization of those affected. Results imply that gender, age and education level and related health literacy of the target groups of respective interventions should be taken into account.

Clinical Profile of Patients with Psoriasis and their Attitude Towards the Illness

Introduction: Psoriasis is a chronic inflammatory hyperproliferative disease of the skin and affects 0.6–4.8% of the world’s population. In addition to the skin and joint manifestations, psoriasis impairs many aspects of individual wellbeing, including emotional, physical, sexual, and financial status. Skin diseases such as psoriasis can profoundly influence a patient’s self-image, self-esteem, and sense of wellbeing. This study aimed to assess the clinical profile of patients with psoriasis and their attitude towards living with the disease. Methods: A cross-sectional descriptive design was used. Two hundred subjects diagnosed with psoriasis were recruited through purposive sampling. A structured proforma was used to assess the clinical profile and attitude was assessed by Psoriasis Attitude Assessment Questionnaire (PSAQ). Results: The most common type of psoriasis was chronic stable psoriasis (86.5%). A family history of psoriasis was present in 30 (15.0%) subjects. Stress was attributed to the exacerbation of disease in 90 (45.0%) subjects. Itching was reported by 124 (62.0%) subjects, and sleep disturbance was reported by 85 (42.5%) of the subjects. The majority of individuals (n: 187; 93.5%) had a moderately favourable attitude towards living with psoriasis. Conclusion: Living with psoriasis can be difficult for patients because of the inconvenience caused by the disease in their daily life. Knowledge about the pathogenesis and treatment of psoriasis may increase the patient’s perception of control and attention to aggravating factors may increase patient’s compliance with treatment and positive lifestyle habits.

Stigmatization and Quality of Life in Patients with Psoriasis

Introduction

Each dermatological condition associated with the presence of visible skin lesions can evoke the following psychological response of the patient: shame, anxiety, anger, or even depression. Psoriasis may additionally be a cause of social rejection, which significantly impairs a patient’s private life and social functioning, and may contribute to stigmatization, alienation, and deterioration of their quality of life. The aim of the study was to determine the level of stigmatization and the quality of life of persons with psoriasis in relation to sociodemographic characteristics.

Methods

The study, which included 166 patients with plaque psoriasis, was carried out with the 33-item Feelings of Stigmatization Questionnaire, Dermatology Life Quality Index (DLQI), and a dedicated sociodemographic survey.

Results

Compared with women, men had higher stigmatization scores in the “Feeling of being flawed” domain (p = 0.0362), and patients up to 30 years of age scored higher on the “Guilt and shame” domain (\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\bar{x}$$\end{document}x¯ = 17.1 points) than those older than 30 years (\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\bar{x}$$\end{document}x¯ = 14.6 points). Also, persons with visible skin lesions presented with higher stigmatization levels in the “Guilt and shame” domain than those without (p = 0.0028). Quality of life in persons with psoriasis did not depend on sociodemographic parameters but correlated significantly with two stigmatization domains, “Sensitivity to the opinions of others” (R = 0.31; p = 0.0030) and “Positive attitudes” (R = 0.27; p = 0.0115).

Conclusions

As stigmatization is a social problem, only greater social awareness of psoriasis may contribute to better understanding and broader acceptance of patients with this dermatosis. To help them to cope with the stigmatization and hence to improve their quality of life, persons with psoriasis should be provided with psychological counselling.

Role of neuroimmune circuits and pruritus in psoriasis

Psoriasis is a chronic inflammatory skin disease presenting with an array of clinical phenotypes, often associated with pruritus. Environmental and psychological stressors can exacerbate psoriasis symptoms and provoke flares. Recent studies suggest a dysfunctional hypothalamic-pituitary-adrenal (HPA) axis in some patients with psoriasis that can result in immune dysregulation. The immune system, in turn, can communicate with the nervous system to induce, maintain or aggravate psoriasis. In the skin, peripheral sensory as well as autonomic nerves control release of inflammatory mediators from dendritic cells, mast cells, T cells or keratinocytes, thereby modulating inflammatory responses and, in case of sensory nerves, pruritus. In response to the environment or stress, cytokines, chemokines, proteases, and neuropeptides fluctuate in psoriasis and influence immune responses as well as nerve activity. Furthermore, immune cells communicate with sensory nerves which control release of cytokines, such as IL-23, that are ultimately involved in psoriasis pathogenesis. Nerves also communicate with keratinocytes to induce epidermal proliferation. Notably, in contrast to recent years the debilitating problem of pruritus in psoriasis has been increasingly appreciated. Thus, investigating neuroimmune communication in psoriasis will not only expand our knowledge about the impact of sensory nerves in inflammation and pruritus and give new insights into the impact of environmental factors activating neuroimmune circuits or of stress in psoriasis, but may also lead to novel therapies. This review summarizes the relevant literature on the role of neuroimmune circuits, stress and how the central HPA axis and its peripheral equivalent in the skin, impact psoriasis.

Exploring genetic targets of psoriasis using genome wide association studies (GWAS) for drug repurposing

Psoriasis is a chronic inflammatory disease causing itching in the body and pain in the joints. Currently, no permanent cure is available at a commercial level for this disease. Genome wide association studies (GWAS) provide a deeper insight that helps in better understanding this disease and further possible cure of this disease. The major goal of the present study is to identify potent genetic targets of psoriasis disease using GWAS approach and identify drugs for repurposing. The methods used include GWAS catalogue, GeneAnalytics, canSAR protein annotation tool, VarElect, Drug bank, Proteomics database, ProTox software. By exploring GWAS catalogue, 126 psoriasis associated genes (PAG) were identified. 68 genes found to be druggable were obtained from canSAR protein annotation tool. Localization results depict that maximum genes are present in cytoplasmic cellular components. The superpathways obtained from GeneAnalytics resulted in involvement of these genes in the immune system, Jak/Stat pathway, Th17 and Wnt pathways. Two genes Interleukin 13 (IL13) and POLI are Food and Drug Administration (FDA) approved targets. Small compounds for these targets were analysed for drug-likeliness, toxicity and mutagenecity properties. The FDA approved drug pandel was found to possess desirable properties. The medications used for psoriasis causes mild to severe side effects and does not work well always. Hence we propose drug repurposing strategy to use existing drugs for new therapies. Therefore, the drug pandel could be explored further and repurposed to treat psoriasis.

Quality of life and psychological impact in the photodermatoses: a systematic review

BACKGROUND

The photodermatoses affect large proportions of the population but their impact on quality of life (QoL) and psychological health has not been reviewed. Several tools are available to evaluate QoL and psychological impacts.

OBJECTIVES

To systematically review current literature to identify tools used to assess QoL and psychological impacts in patients with photodermatoses, and to summarize the reported findings.

METHODS

A systematic search of PubMed, OVID Medline, PsycInfo and CINAHL was performed for articles investigating QoL and/or psychological impact in patients with photodermatoses, published between 1960 and September 2018.

RESULTS

Twenty studies were included: 19 incorporated QoL assessment while three evaluated psychological morbidity. Six QoL tools were found to be used: Dermatology Life Quality Index (DLQI), Children's DLQI, Family DLQI, Skindex (16- and 29-item versions), Erythropoietic Protoporphyria Quality of Life (EPP-QoL) and EuroQol. Between 31% and 39% of photosensitive patients reported a very large impact on QoL (DLQI > 10). Employment and education, social and leisure activities, and clothing choices were particularly affected. Only one tool was specifically designed for a photodermatosis (EPP-QoL). Four tools were used to evaluate psychological impact: the Hospital Anxiety and Depression Scale, Fear of Negative Evaluation, brief COPE and Illness Perception Questionnaire-Revised. Levels of anxiety and depression were approximately double British population data. Patients with facial involvement, female gender and younger age at onset showed more psychological morbidity.

CONCLUSIONS

Several tools have been used to assess QoL in the photodermatoses, and confirm substantial impact on QoL. Development of specific, validated QoL measures would address their unique impacts. Research delineating their psychological comorbidity is sparse and requires further exploration. What's already known about this topic? The photodermatoses negatively impact quality of life (QoL) and cause psychological distress, but no reviews of this area appear in the literature. What does this study add? Few studies have explored the psychological and social impacts of the photodermatoses. There are no fully validated QoL tools specific to the photodermatoses. Around one-third of adult and child patients with photosensitivity experience very or extremely large impact on QoL, with particular effect on clothing choices, employment and social and leisure activities. Studies suggest anxiety and depression levels in these patients are around double those in the U.K. general population. More attention is required on these 'hidden' conditions.

Quality of life, anxiety and depressive symptoms in patients with psoriasis: A case-control study

OBJECTIVE

To compare quality of life (QoL), anxiety and depressive symptoms, alcohol consumption and other correlates between patients with psoriasis and controls; and to identify features of psoriasis associated with lower levels of QoL.

METHOD

Case-control study including 70 subjects with moderate-severe psoriasis and 140 controls without psoriasis. All participants answered the Short Form Health Survey (SF-36), with physical and mental component scores of quality of life, and the Hospital Anxiety and Depression Scale (HADS). Among subjects with psoriasis, the Psoriasis Area and Severity Index (PASI) and the Dermatology Life Quality Index (DLQI) were used, respectively, to measure the severity of psoriasis and the impact of psoriasis on the specific quality of life.

RESULTS

Compared to controls, patients with psoriasis showed higher HADS depression score and alcohol consumption, and lower QoL. Among subjects with psoriasis, multivariate analysis showed: 1) poorer physical QoL was associated with older age, articular lesions and anxious symptoms, whereas poorer mental QoL was associated with younger age, female sex, genital lesions and depressive symptoms; 2) the higher the severity of psoriasis, the lower the level of QoL and the higher the levels of anxious or depressive symptoms; and 3) female sex and articular or genital location of lesions are linked with higher HADS scores.

CONCLUSION

Higher scores in anxiety and depression and lower QoL is common in psoriasis, especially among women and those with genital or articular lesions. Dermatologists should give special attention to this subgroup of persons with psoriasis in order to prevent future psychopathology.

Stigmatization in Arabic psoriatic patients in the United Arab Emirates - a cross sectional study

Introduction

Stigmatization is the phenomenon of labeling negatively people who differ from social norms in some aspect. It seems to be a common and important problem in dermatology. Psoriasis, being a chronic and recurrent skin disease, is frequently associated with various psychosocial consequences.

Aim

To evaluate the stigmatization level in an Arabic population of psoriatic individuals.

Material and methods

A total of 108 consecutive patients suffering from psoriasis were enrolled in the study. All recruited subjects were of Arabic origin. Severity of psoriasis was documented with the Psoriasis Area and Severity Index (PASI). Stigmatization was assessed with validated Arabic language versions of the 6-item Stigmatization Scale and the Feelings of Stigmatization Questionnaire. Moreover, all patients were asked to complete the Dermatology Life Quality Index (DLQI) questionnaire.

Results

The majority of patients showed feelings of stigmatization due to psoriasis. The mean level of stigmatization was 5.6 ±4.5 points assessed by the 6-item Stigmatization Scale and 98.4 ±26.4 points by the Feelings of Stigmatization Questionnaire. Positive attitudes and feeling of being flawed were the most bothersome aspects of stigmatization expressed by patients. Involvement of the face appeared to be the only independent factor influencing the stigmatization level. In the Feelings of Stigmatization Questionnaire, itching was found to be a factor responsible for feelings of stigmatization.

Conclusions

Our study indicated that stigmatization is common among psoriatic Arabic patients. We postulate that measurement of stigmatization level could contribute to the holistic therapeutic approach of psoriatic patients.

The stigma of skin disease

PURPOSE OF REVIEW

The effects of skin disease on stigmatization are important but understudied in the pediatric population. Given the highly visible nature of dermatologic conditions, stigmatization is a common problem that requires significant attention in patients with skin diseases. In this review, we examine the recent literature addressing stigmatization of patients suffering from common dermatologic diseases with the goal to increase clinician awareness of these issues and identify new avenues for future research.

RECENT FINDINGS

A number of studies have examined the impact of skin disease on psychosocial well being and quality of life. Although some skin diseases are often overlooked medically and considered to be primarily cosmetic issues, the long-term consequences of skin diseases on psychosocial health, especially in pediatric patients, can be profound.

SUMMARY

The precipitating factors for stigma vary widely depending on age, sex, and culture. In order to effectively reduce the impact of pediatric skin diseases on psychosocial health, physicians should be able to identify specific characteristics that may increase risks for stigmatization in chidlren. Carefully monitoring psychosocial development in pediatric patients with dermatological conditions in addition to proactively guiding patients and families to appropriate resources can benefit the child's development and overall long-term well being.

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.

Psoriasis and Depression: The Role of Inflammation

Psoriasis is a chronic, systemic inflammatory disorder with multiple comorbidities. The most common comorbidities are mental disorders, especially depression, which can interact negatively with psoriasis to produce a dangerous vicious circle. Depression in psoriasis has traditionally been explained as a response to psychosocial factors and impaired quality of life. However, a new hypothesis linking depression and psoriasis through chronic inflammation offers insights that should help to understand and treat these diseases. In this approach, new drugs and lifestyle have an important role.

Physiological and behavioral reactivity to social exclusion: a functional infrared thermal imaging study in patients with psoriasis

Recent studies have shown that sympathetic nervous system (SNS) activity can be heavily impacted not only by basic threats to survival but also by threats to social bonds. In this study we explored the behavioral and physiological consequences of social exclusion/inclusion in patients with psoriasis, a disease frequently associated with the experience of being ostracized and with deficient emotion regulation skills. We employed a virtual ball-tossing game (Cyberball) to induce the experience of social exclusion/inclusion. We then used a Trust Game to measure the effects of this social modulation on trust. During Cyberball, infrared thermal imaging was used to record participants' facial temperature and thus obtain an online measure of SNS activation. Behavioral data showed that social exclusion shifted participants' trust toward unfamiliar players who had not previously excluded them. Physiological data indicated that in control participants, social exclusion triggered higher SNS activation than inclusion. No such effect was found in patients with psoriasis, whose SNS activity was the same during inclusion as it was during exclusion, suggesting that they benefit less from inclusive experiences than control participants. In addition, in patients but not in controls, higher SNS activation during social exclusion was linked to higher monetary investment toward unfamiliar players, a result in keeping with the social reconnection hypothesis, according to which emotions triggered by social rejection can be regulated by investing in new social interactions. We also found that an increase in periorbital temperature is accompanied by a decrease in happiness ratings after social exclusion was experienced during the Cyberball game. NEW & NOTEWORTHY Previous research on emotional processes in psoriasis has mainly employed self-report measures. In this study we used thermal imaging to obtain an online measure of the sympathetic nervous system (SNS) activity during social exclusion and tested how this experience influenced subsequent trust. We found that being included was a less positive experience for patients compared with controls and that SNS activity during exclusion had a stronger influence on subsequent trust in patients than in controls.

Cognitive load and emotional processing in psoriasis: a thermal imaging study

Psoriasis is a chronic dermatologic disease which is frequently associated with psychological distress. Although studies suggest a relationship between this condition and difficulties in emotion regulation, behavioral and physiological evidence about this link is scarce. We measured implicit emotion regulation abilities of psoriasis patients and a healthy control group by examining the impact of distracting emotional (positive, negative or neutral) images on a working memory task ("Emotional N-Back") which could present high (2-back) or low (1-back) cognitive workload. Moreover, we used Functional Infrared Thermal Imaging to record participants' facial temperature and obtain a measure of the activation of the autonomic system. Rising of temperature over the peri-orbital areas and the nose tip are believed to reflect the activation and the de-activation of the sympathetic system, respectively. Patients scored higher than controls on the "Lack of emotional clarity" sub-scale of the Difficulties in Emotion Regulation Scale. Compared to controls, who performed much better in the low vs. high cognitive load condition, patients showed a smaller accuracy difference between the two conditions. Moreover, patients showed less sympathetic (lower peri-orbital and higher nasal tip temperature) activity (especially in the negative and neutral blocks) during the high vs. low cognitive load condition, suggesting that the former condition might be less emotionally demanding for them. Patients benefit more than controls from the load-dependent interference effect when dealing with emotional information; thus, therapeutic techniques aiming at teaching how to use cognitive strategies to downregulate emotions might be particularly appropriated for them.

Stigmatizing attitudes toward persons with psoriasis among laypersons and medical students

BACKGROUND

Perceived stigma among patients with psoriasis contributes to poor quality of life.

OBJECTIVE

To determine the prevalence and predictors of stigmatizing attitudes toward persons with psoriasis among laypersons and medical trainees.

METHODS

Laypersons were recruited from Amazon.com's Mechanical Turk (MTurk) (n = 198). Additionally, 187 medical students were recruited via e-mail. Participants completed an online survey in which they viewed images of persons with visible psoriasis. Participants reported their desire to socially avoid the persons in the images, their emotional responses to the persons in the images, and their endorsement of psoriasis-related stereotypes and myths.

RESULTS

MTurk participants endorsed social avoidance items such as not wanting to shake hands with (39.4%) or have the persons in the images in their home (32.3%). Participants stereotyped persons with psoriasis as contagious (27.3%) and endorsed the myth that psoriasis is not a serious disease (26.8%). Linear regression analyses showed that having heard of or knowing someone with psoriasis predicted fewer stigmatizing attitudes (P < .05). The medical students reported less stigmatizing attitudes than the MTurk participants (P < .01).

LIMITATIONS

Self-report, single-institution study.

CONCLUSION

Stigmatizing views of persons with psoriasis are prevalent among people in the United States. Educational campaigns for the public and medical trainees may reduce stigma toward persons with psoriasis.

Bidirectional relationships between psychological health and dermatological conditions in children

Dermatological conditions are common among children. They are a frequent cause of presentation to health care services and a leading contributor to burden of disease. Evidence supports the notion that bidirectional relationships exist between children’s physical and psychological health, whereby the child’s dermatological condition can impact their psychological health and well-being, while, in the reverse direction, psychological factors (eg, stress) can impact the severity and course of the child’s skin disease. The psychological impact of dermatological conditions in childhood needs to be taken into account during the assessment, planning, and treatment phases of management. Likewise, the potential effect of children’s emotional and behavioral difficulties on management, particularly in terms of the impact on parents’ ability to implement their child’s treatment plan, should be considered. This literature review summarizes the current evidence for the relationships between three common chronic dermatological conditions of childhood – atopic dermatitis, psoriasis, and urticaria – and psychological adjustment and quality of life in childhood. Overall, a general paucity of research in the pediatric context – combined with limitations in terms of study design, variability in operationalization of constructs, and heterogeneity in measurement of outcomes – makes it difficult to draw firm conclusions in this area. Based on the available research, implications for successful long-term management of these conditions are discussed in terms of integrating psychological and parenting support with medical management to improve adherence, reduce disease severity, and improve quality of life for children and their families.

Comparison of mental health outcomes among adults with psoriasis on biologic versus oral therapies: a population-based study

PURPOSE

We sought to compare the impact of biologic versus oral therapies on mental health outcomes among adult U.S. residents with moderate-to-severe psoriasis.

METHODS

We performed a nationwide, cross-sectional study comparing 2,303,534 (weighted) adults with moderate-to-severe psoriasis on biologic versus oral therapies and their associated mental health outcomes using the 2003-2015 Medical Expenditure Panel Survey (MEPS). Mental health outcomes were measured with the Kessler 6 (K6), a validated measure of psychological distress, and Patient Health Questionnaire 2 (PHQ2), a screening tool for depression.

RESULTS

The mean K6 score for residents on biologic therapies was significantly lower than that of residents on oral therapies (2.72 [95% CI: 2.27-3.17] versus 3.70 [95% CI: 3.27-4.12]; p < .001). The mean PHQ2 score for residents on biologic therapies was also significantly lower than that of residents on oral therapies (0.540 [95% CI: 0.390-0.690] versus 0.890 [95% CI: 0.749-1.031]; p < .001). Based on adjusted multivariable linear regression models, biologic therapy was associated with significant reductions in K6 (p < .001) and PHQ2 (p = .016) scores compared to oral therapy.

CONCLUSIONS

Therapeutic choices for psoriasis impact mental health outcomes. Biologic therapy is associated with reductions in psychological distress and depression as compared to oral therapy in the U.S. adult moderate-to-severe psoriasis population.

Determinants of quality of life and psychological status in adults with psoriasis

We investigated whether disease severity and clinical manifestations were associated with depression, anxiety, stress and quality of life in adults with psoriasis. Participants were recruited from a dermatology outpatient clinic at a teaching hospital. Information on sociodemographic characteristics, disease severity, presence of arthropathy and head involvement was specifically recorded. Disease severity was assessed using the Psoriasis Area and Severity Index (PASI). Quality of life and psychological symptoms were measured using the Dermatology Life Quality Index (DLQI) and the Depression Anxiety Stress Scale (DASS), respectively. One hundred individuals were recruited. Unadjusted analysis revealed that head involvement was associated with depression [odds ratio (OR) 8.509; 95% confidence interval (CI) 1.077-67.231] and anxiety (OR 6.46; 95% CI 1.401-29.858). Severe disease was associated with a poorer quality of life compared to mild disease (OR 3.750; 95% CI 1.330-10.577). Younger age was associated with an increased risk of depression [mean difference (MD) - 8.640; 95% CI - 16.390 to - 0.890], anxiety (MD - 11.553; 95% CI - 18.478 to- 4.628), stress (MD - 11.440; 95% CI - 19.252 to - 3.628) and severely impaired quality of life (MD - 12.338; 95% CI - 19.548 to - 5.127). Following adjustments for age and disease severity, anxiety, stress and depression remained associated with severely impaired quality of life.

Incremental health care services and expenditures associated with depression among individuals with cutaneous lupus erythematosus (CLE)

Objectives

The objective of this paper is to describe the annual direct medical expenditures for cutaneous lupus erythematosus (CLE) patients, and to estimate the incremental health care expenditures and utilization associated with depression among adults with CLE, while controlling for covariates.

Methods

Using the 2014 Medical Expenditure Panel Survey (MEPS), we compared CLE patients with and without depression to determine differences in: (a) health care utilization—inpatient, outpatient, office-based and emergency room (ER) visits, and prescriptions filled; and (b) expenditures—total costs, inpatient, outpatient, office-based, ER, and prescription medication costs, and other costs using demography-adjusted and comorbidity-adjusted multivariate models (age, gender, race/ethnicity, marital status, education, perception of health status, poverty category, smoking status, and Charlson Comorbidity Index).

Results

The total direct medical expenditure associated with CLE is estimated at approximately $29.7 billion in 2014 US dollars. After adjusting for covariates, adults with CLE and depression had more hospital discharges (utilization ratio (UR) = 1.13, 95% confidence interval (CI) (1.00–1.28)), ER visits (UR = 1.17, 95% CI (1.09–1.37)), and prescribed medicines (UR = 2.15, 95% CI (1.51–3.05)) than those without depression. Adults with CLE and depression had significantly higher average annual total expenditure that those without depression ($19,854 vs. $9735).

Conclusions

High health care expenditures are significant for patients with CLE, especially among those with depression. Prescription drugs, inpatient visits, and ER visits contributed most to the total expenditures in CLE patients with depression. Early diagnosis and treatment of depression in CLE patients may reduce total health care expenditures and utilization in this population.

Stress and skin disease quality of life: the moderating role of anxiety sensitivity social concerns

BACKGROUND

Stress is an important factor in the onset, exacerbation and reoccurrence of many skin diseases. Little is known about psychological risk factors that affect the association between stress and dermatological conditions. One relevant factor that may modulate this link is anxiety sensitivity (AS) social concerns - the propensity to respond fearfully to anxiety-related sensations (e.g. sweating, flushing) owing to perceived social consequences (e.g. rejection or humiliation).

OBJECTIVES

To gain insight into psychological factors affecting skin disease, we examined the moderating role of AS social concerns in the relationship between stress and skin disease quality of life (QoL).

METHODS

Participants [n = 237 (161 female), mean ± SD age 34·18 ± 9·57 years] with active skin disease symptoms were recruited online and completed questionnaires assessing stress, AS social concerns, skin disease QoL and global skin disease symptom severity.

RESULTS

AS social concerns moderated the association between stress and skin-related emotional and social functioning in adults with skin disease. Stress was a significant predictor of the impairment associated with skin disease.

CONCLUSIONS

Stress was linked to skin disease-related emotional and functional impairment associated with skin disease among individuals with high AS social concerns. These results highlight the potential for AS reduction interventions to break the vicious cycle of stress and skin disease symptoms and to improve psychosocial well-being in dermatology patients.

Psychosocial Distress of Patients with Psoriasis: Protocol for an Assessment of Care Needs and the Development of a Supportive Intervention

BACKGROUND

Psoriasis is a chronic inflammatory disease that is often associated with a number of somatic and mental comorbidity. Patients with psoriasis show an increased risk of depression and (social) anxiety.

OBJECTIVE

The aims of this study are 1) to explore the psychosocial distress of patients with psoriasis and to assess their care needs; and 2) to develop a supportive intervention based on the prior results.

METHODS

A multi-stage design with four phases combining quantitative and qualitative methodology will be used and conducted in two centers. 1) A scoping review and focus groups will be used to design a questionnaire to assess the psychosocial distress and care needs of the patients. 2) The questionnaire developed in phase 1 will be used in a cross-sectional survey to assess the extent of psychosocial distress and supportive care needs in 400 patients with psoriasis. 3) A systematic review and meta-analysis will be conducted to identify psychosocial and psychoeducational interventions for patients with psoriasis and to describe their effectiveness. 4) Based on the results of the phases 2 and 3 a manualized supportive intervention will be developed and the feasibility and acceptance of the intervention will be assessed.

RESULTS

Currently, phase 1 of the project has been completed and the recruitment for phase 2 has been started. The systematic review and meta-analysis of phase 3 are conducted simultaneously to phase 2 and results are expected soon. Phase 4 has not been started yet.

CONCLUSIONS

The expected results of this study will show the extent of psychosocial distress of patients with psoriasis in Germany and supplement previous research with findings about the supportive care needs of this patient group. Moreover, the developed intervention will help to address the psychosocial support needs of patients with psoriasis. Research shows that psychosocial support is strongly needed.

Associations between site of skin lesions and depression, social anxiety, body-related emotions and feelings of stigmatization in psoriasis patients

INTRODUCTION

Research has demonstrated a link between psoriasis and a multitude of psychological impairments; however, relatively few studies have examined the importance of site of skin lesions for negative psychological outcomes in psoriasis patients.

AIM

To investigate relationships between anatomical location of psoriatic lesions and experiences of stigmatization, negative emotional attitude towards the body, depression and social anxiety.

MATERIAL AND METHODS

Adult psoriasis patients (N = 193) completed the Stigmatization Scale, the Body Emotions Scale, the Beck Depression Inventory and the Social Anxiety Questionnaire. The body surface area index was used to assess the location and extent of psoriasis.

RESULTS

Feelings of stigmatization were found to be most closely related to the presence of psoriatic lesions on the chest, and the arms and hands. Higher levels of social anxiety were found to be most closely related to the location of psoriatic lesions on the head and neck. Negative emotional attitude towards the body was found to be most closely related to the location of psoriatic lesions on the arms and hands, and on the head and neck. Higher levels of depressive symptoms were most closely related to the presence of psoriatic lesions on the head and neck, the arms and hands, and the genital area.

CONCLUSIONS

The presence of psoriatic lesions on the head, neck, and chest, and also on the arms and hands and the genital area, should alert clinicians to a higher risk of psychological impairments. This may help to better recognize and prevent cumulative life course impairment.

Psychiatric comorbidity and suicidal ideation in psoriasis, melanoma and allergic disorders

OBJECTIVE

Psychiatric disorders and suicide risk (especially in psoriasis) are frequent and disabling conditions in patients with skin diseases. The aim of this study was to examine the risk of suicide and stressful life events in a sample of patients with skin disease.

METHODS

A sample of 242 dermatological patients (142 women and 100 men), 112 of which had psoriasis, 77 had melanoma, and 53 were suffering with chronic allergic diseases. Patients were administered the MINI International Neuropsychiatric Interview (MINI), Hamilton Depression Rating Scale (HDRS), Hamilton Anxiety Rating Scale (HARS), and the Columbia-Suicide Severity Rating Scale (C-SSRS). Patients were also asked about their experiences with stressful life events.

RESULTS

Patients with psoriasis were more likely to have a history of psychiatric disorders (36.6% vs. 13.2% χ²₍₁₎ = 9.55; p = 0.002) compared to patients with allergies. Specifically, patients with psoriasis more likely had a diagnosis of a mood disorder (16.1% vs. 3.9% χ²₍₁₎ = 6.85; p = 0.009; 16.1% vs. 0% χ²₍₁₎ = 9.56; p = 0.002) and reported past suicidal ideation (33.9% vs. 15.6% χ²₍₁₎ = 7.89; p = 0.005; 33.9% vs. 18.9% χ²₍₁₎ = 3.96; p = 0.047) as compared to those with melanoma and allergy.

CONCLUSIONS

The results from this study suggest that patients affected by psoriasis have an increased risk of psychiatric comorbidities and suicidal ideation compared to those who have other dermatological disorders.
