Stigmatizing attitudes toward persons with psoriasis among laypersons and medical students

Impact of Atopic Dermatitis on Adult Women's Lives: A Survey of 1,009 French Women

Atopic dermatitis (AD) is one of the most common inflammatory diseases, and has a higher prevalence among females in adulthood. The aim of this observational, cross-sectional, survey-based study was to evaluate the impact of AD on the daily lives of adult women patients. A scientific committee composed exclusively of women constructed a specific questionnaire in partnership with the French Eczema Association. Severity of AD was evaluated with the Patient-Oriented Eczema Measure (POEM). A sample of 1,009 adult women (mean age ± standard deviation: 41.8 ± 14.2 years) with AD was identified from a representative sample of the French population (82% response rate 1,230 women surveyed). According to the POEM, 50.64% (n = 511) of subjects were identified as having mild AD, 39.35% (n = 397) moderate AD, and 10.01% (n = 101) severe AD. Overall, 67.7% (n = 682) reported that their eczema involved a visible area (face, neck or hands), and 19.6% (n = 198) a sensual area (breasts/chest, genital area or buttocks). Of the 720 women with menstrual cycles, exacerbations of AD were reported to occur mostly before (50.6%) and during (48.3%) menstruation. A small proportion of women, 7.3% (n = 74), reported being afraid of  becoming pregnant because of their eczema. If AD involvement was in a visible area it had a greater impact on romantic relationships, sexual relationships and occupation. If AD involvement was in a sensual area it had a greater influence on romantic relationships and sexuality. Particular attention should be given to patients with localization of AD on the face, neck or hands, as they have a higher risk of social exclusion. Moreover, these results should encourage health professionals to ask patients with AD about the possible involvement of sensual areas.

Knowledge, attitude, and practice of psoriasis patients toward their diseases: a web-based, cross-sectional study

Objective

To investigate the knowledge, attitude, and practice (KAP) of psoriasis patients toward the disease.

Methods

A web-based cross-sectional study was conducted among psoriasis patients who were diagnosed at the outpatient of Shaanxi Provincial People's Hospital in March 2023. A self-designed questionnaire was administered for data collection and KAP assessment.

Results

A total of 526 valid questionnaires were included, including 257 males (48.86%) psoriasis patients. Their mean KAP scores were 8.09 ± 3.60 (possible range: 0-12), 31.94 ± 4.61 (possible range: 10-50), and 51.92 ± 8.83 (possible range: 15-75), respectively. Pearson's correlation analysis showed a positive correlation between knowledge and attitude (r = 0.186, p < 0.001), a positive correlation between knowledge and practice (r = 0.313, p < 0.001), and a negative correlation between attitude and practice (r = -0.181, p < 0.001). Moreover, structural equation model showed that medication (β = 2.74, 95% CI: 2.17, 3.32, p < 0.001) has significantly positive effect on knowledge. Education (β = 0.56, 95% CI: 0.31, 0.81, p < 0.001) and duration of psoriasis (β = 1.01, 95% CI: 0.54, 1.49, p < 0.001) have significantly positive effect on attitude. Knowledge (β = 1.03, 95% CI: 0.80, 1.26, p < 0.001) and medication (β = 4.59, 95% CI: 2.78, 6.40, p < 0.001) has significantly positive effect on practice, while attitude (β = -0.41, 95% CI: -0.57, -0.26, p < 0.001) and duration of psoriasis (β = -2.53, 95% CI: -3.49, -1.57, p < 0.001) exhibit significantly negative effect on practice.

Conclusion

Psoriasis patients have good knowledge, positive attitude, and proactive practice toward the disease. Education, medication, duration of psoriasis might have effect on their KAP.

Prevalence and Causes of Stigmatization Among Patients With Chronic Skin Diseases in Saudi Arabia

BACKGROUND

Skin diseases can lead to stigmatization with negative consequences for patients' quality of life and mental health.

AIM

The aim of this study was to estimate the prevalence of stigmatization experienced by patients with vitiligo, psoriasis, acne, rosacea, or atopic dermatitis and to assess the relationships between the level of stigmatization and patient characteristics.

METHODS

This cross-sectional study included adult patients with vitiligo, psoriasis, acne, rosacea, or atopic dermatitis attending the dermatology clinics of various general hospitals in Saudi Arabia. Stigma levels were assessed using the six-item Stigma Scale.

RESULTS

The prevalence of stigmatization was 90.4% among the 280 patients included. Multiple regression analyses revealed the factors that independently and significantly increased the level of stigmatization. These included male gender (B = 4.300, 95%CI 3.407-5.192, P <0.001), positive family history of skin conditions (B = 2.267, 95%CI 1.139-3.395, P <0.001), number of skin diseases (B = 2.357, 95%CI 0.998-3.716, P = 0.001), and presence of facial lesions (B = 2.455, 95%CI 1.206-3.705, P<0.001).

CONCLUSIONS

The prevalence of stigmatization is high among patients with chronic skin diseases in Saudi Arabia. Identifying patients at risk for high levels of stigmatization may allow them to be provided with appropriate social and psychological support.

Evaluation of Stigma Toward Individuals With Acne

Importance

Little is known about the prevalence and magnitude of stigmatizing attitudes of the general public toward individuals with acne.

Objective

To explore the degree of stigma toward individuals with acne and whether these attitudes vary based on characteristics of the individuals with acne or of the survey participants.

Design, Setting, and Participants

In this cross-sectional internet survey study, 4 stock portraits of adults that varied in sex (male/female) and skin tone (light/dark) were digitally enhanced to have acne (mild/severe). One of these 12 images was randomly presented to survey participants, who subsequently answered questions regarding stigmatizing attitudes with respect to the pictured individual, such as desire for social distance and stereotype endorsement. The survey was administered to a convenience sample of adult respondents in the US who were volunteers on the ResearchMatch platform.

Main Outcomes and Measures

Prevalence and magnitude of stigma toward individuals with acne.

Results

The survey was completed by 1357 respondents (65.7% completion rate) (mean [SD] age, 42.4 [14.3] years; 918 [67.7%] female, 439 [32.4%] male). Compared to those with no acne, for those with severe acne, participants reported less comfort being friends (adjusted coefficient [95% CI], -0.28 [-0.47 to -0.10]; P = .003), hiring (-0.33 [-0.51 to -0.15]; P < .001), having physical contact (-0.26 [-0.45 to -0.08]; P = .006), dating (-0.44 [-0.74 to -0.14]; P = .004), and posting a photograph together on social media (-0.50 [-0.70 to -0.30]; P < .001). Compared to those with no acne, participants were more likely to rate individuals with severe acne as having poor hygiene (adjusted coefficient [95% CI], -1.04 [-1.46 to -0.82]; P < .001) and being unattractive (-0.89 [-1.12 to -0.67]; P < .001), unintelligent (-0.42 [-0.63 to -0.22]; P < .001), unlikable (-0.36 [-0.56 to -0.15]; P < .001), immature (-0.52 [-0.74 to -0.30]; P < .001), and untrustworthy (-0.40 [-0.61 to -0.18]; P < .001). There was evidence that the effect size of the association of acne with desire to social distance was greater for individuals with dark skin.

Conclusions and Relevance

This survey study demonstrates that stigmatizing attitudes toward patients with acne existed across a variety of social and professional scenarios, with severe acne and acne in darker skin tone being associated with a greater degree of stigma. These findings highlight the need to identify approaches to reduce stigmatizing attitudes in the community and for adequate access to care, which might prevent negative downstream effects related to these stigmatizing attitudes.

[Stigmatization and social anxiety in patients with skin diseases]

Stigmatization of patients with skin diseases has only recently attracted more attention in research. However, both external stigmatization by society and self-stigmatization by the affected patients are widespread in patients with skin diseases. Many studies show that in this group of patients, the experience of both kinds of stigmatization is associated with psychosocial burden, such as social anxiety. This is often independent of the visibility of skin lesions. The psychosocial burden of affected individuals may lead to psychological comorbidities, such as depression or anxiety disorders, making it important to screen patients in dermatologic settings for the presence of these conditions. Interventions to reduce external and self-stigmatization have been developed, but more randomized controlled trials are needed to test the effects of such interventions.

Knowledge, attitudes, and perceptions of hidradenitis suppurativa among young adults in Singapore

Background

The prevalence of hidradenitis suppurativa (HS) is 0.00033% to 4.10% globally. Few epidemiological studies derive from Asia, with social stigmatization postulated to result in under-diagnosis.

Objective

This study aimed to assess the self-reported prevalence of HS, and the knowledge, attitudes, and perceptions towards HS among Singaporean young-adults.

Methods

A cross-sectional study (n = 158) was conducted by anonymous online questionnaire. The association between demographic factors and risk of potentially undiagnosed HS was evaluated using multivariable logistic regression. Differences between attitude-perception scores by demographic factors and knowledge of HS were tested using two-sample t-tests.

Results

The prevalence of diagnosed and potentially undiagnosed HS was 0.63% and 8.9%, respectively. Non-Chinese had significantly higher social attitude-perception scores than Chinese (P = .029). Females had significantly higher social (P = .048) as well as economic and work (P = .037) attitude-perception scores than males. Those with knowledge of HS had significantly higher attitude-perception scores for interpersonal (P = .031) and social (P = .0052) subsections.

Limitations

Small sample size, low frequency of HS cases, and self-reported prevalence may not generalize to the broader population in Singapore.

Conclusion

Our results suggest a potential underdiagnosis of HS. Non-Chinese stigmatize HS less than Chinese, and females less than males. Individuals with knowledge of HS might be more open to interpersonal and social interactions with HS sufferers.

The Potential of Instagram to Reduce Stigmatization of People with Psoriasis: A Randomized Controlled Pilot Study

Psoriasis is a stigmatized skin disease. This randomized controlled trial aimed to evaluate an Instagram based stigma-reduction intervention targeting daily Instagram users aged 18 to 49 years without psoriasis. After stratification for baseline characteristics (t0), stigmatization of psoriasis was assessed using a questionnaire and a photo-rating task immediately before (t1) and after (t2) the intervention and two weeks post-intervention (t3). Data from 54 participants, recruited in a university setting and via Instagram, were analysed. For 10 min between t1 and t2, the intervention group (n = 26) and the control group (n = 28) scrolled through two different Instagram accounts. Psoriasis-sensitizing content was displayed to the intervention group while beauty-glorifying posts were shown to the control group. Results indicated significantly less Disease-related Misconceptions in the intervention group in comparison to the control group at t2 (U = 145.50, Z = -3.79, p < 0.001) and at t3 (U = 177.00, Z = -3.25, p = 0.003). Moreover, the intervention group showed a significant reduction over time in Stereotype Endorsement (F(2, 50) = 13.40, p < 0.001, partial η² = 0.35) and Disease-related Misconceptions (χ2(2) = 12.64, p = 0.002). These findings suggest that addressing psoriasis on Instagram has the potential to effectively reduce the related stigmatization. Further studies are necessary to assess the impact of social media on stigmatization concerning psoriasis in more depth.

Patient Unique Stigmatization Holistic tool in dermatology (PUSH-D): Development and validation of a dermatology-specific stigmatization assessment tool

BACKGROUND

The skin plays an important role in establishing interpersonal relationships, and thus visible skin disorders, which have a significant impact on physical appearance, influence other people's behaviours and attitudes.

OBJECTIVE

To develop and validate a dermatologic-specific questionnaire to evaluate stigmatization in individuals with visible skin conditions.

METHODS

Items were generated by a verbatim report based on qualitative interviews with patients with various dermatologic conditions. Subsequently, a study was implemented for psychometric analysis. A dermatology-specific stigmatization questionnaire (PUSH-D) was refined via item reduction according to inter-question correlations, consensus among experts and exploratory factor analysis. Internal consistency was determined by calculating Cronbach's α. Concurrent validity was determined by calculating the correlation between PUSH-D and the Dermatology Life Quality Index (DLQI) and the Rosenberg Self-Esteem Scale (RSES).

RESULTS

From a primary list of 22 items, PUSH-D was reduced to a 17-item questionnaire, covering two pertinent dimensions based on the exploratory factor analysis. Construct validity was demonstrated, and PUSH-D showed good internal consistency (Cronbach's α = 0.9). PUSH-D correlated strongly with the DLQI 0.72 (p < 0.001) and moderately with the RSES 0.49 (p < 0.001).

CONCLUSION

PUSH-D allows a comprehensive view of the degree of stigmatization in visible skin disorders, as well as the comparability of stigmatization levels across various skin conditions.

Burden of visible [face and hands] skin diseases: Results from a large international survey

BACKGROUND

While numerous surveys over the last decade have evaluated the burden of skin diseases, none have focused on the specific impact of disease-location on the hands and face.

AIM

The purpose of our study was to evaluate the burden of 8 skin diseases on the multidimensional aspects of subjects' daily lives in respect to their location on visible body areas (face or hands) versus non-visible areas.

METHODS

This was a population-based study in a representative sample of the Canadian, Chinese, Italian, Spanish, German and French populations, aged over 18 years using the proportional quota sampling method. All participants were asked (i) to complete a specific questionnaire including socio-demographic characteristics, (ii) to declare if they had a skin disease. All respondents with a skin disease were asked (iii) to specify the respective disease locations (hands, face, body) and (iv) to complete the DLQI questionnaire. Respondents with 8 selected skin diseases were asked (v) to complete a questionnaire evaluating the impact of the skin disease on their daily life, including their professional activity, social relations, emotional and intimate life, leisure, sports activities and perceived stigma.

RESULTS

A total of 13,138 adult participants responded to the questionnaire, of whom 26.2 % (n = 3,450) had skin diseases, and 23.4 % (n = 3,072) reported having one of the 8 selected skin diseases. Fifty-three percent were women and the mean age was 39.6 ± 15.5 years. The QoL was mostly impaired when the visible localization was solely on the hands as compared with the face (38 % had a DLQI > 10 versus 22 % respectively). More subjects with a visible localization on the hands reported felt-stigma, having difficulty falling asleep and felt that their sex life had been affected.

CONCLUSION

Special attention should be given to patients with skin disease on the hands and face as they are at higher risk of social exclusion and lower quality of life.

Self-disgust in Patients with Dermatological Diseases

BACKGROUND

Dermatological diseases can be associated with symptoms such as oozing pus, weeping, and/or bleeding, which represent primary disgust elicitors. This study examined the role of self-disgust in people with different skin conditions (e.g., hidradenitis suppurativa, psoriasis, lichen sclerosus).

METHODS

A self-selected sample of 200 dermatology patients completed questionnaires for the assessment of self-disgust, experienced stigmatization, symptoms of depression, anxiety, and somatization. Multiple regression analysis and mediation analysis were computed to examine the relationship between self-disgust and the other selected variables.

RESULTS

Sixty-four percent of the patients reported elevated self-disgust. Sex, age, depression, and perceived stigmatization were predictors of self-disgust. Depression mediated the relationship between stigmatization (e.g., staring by others) and self-disgust.

CONCLUSIONS

This study points to the important role of self-disgust in dermatological conditions. Public health programs to counteract stigmatization of patients with skin diseases as well as therapy approaches that help decrease patients' self-disgust and increase self-acceptance are urgently needed.

A Structured Intervention for Medical Students Significantly Improves Awareness for Stigmatisation in Visible Chronic Skin Diseases: A Randomised Controlled Trial

People with visible skin diseases often experience stigmatisation. The aim of this study was to develop and evaluate a new intervention for medical students to counter the stigmatisation of people with skin diseases. The intervention was evaluated using a randomised controlled design. Effectiveness was assessed at 3 time points. Data from 127 participants were analysed. Regarding the outcome “social distance”, a significant difference between the measurement points was observed for the intervention group (χ²(2) = 54.32, p < 0.001), which also showed a significant effect on agreement with negative stereotypes (F(1.67, 118.67) = 23.83, p < 0.001, partial η² = 0.25). Regarding the outcome “agreement with disease-related misconceptions”, a significant difference between the measurement time points was observed for the intervention group (χ²(2) = 46.33, p < 0.001); similar results were found for the outcome “stigmatising behaviour” (F(1.86, 131.89) = 6.16, p = 0.003, partial η2 = 0.08). The results should encourage medical faculties to invest in such courses in order to prevent stigmatisation of people with skin diseases.

Stigmatization in Patients With Psoriasis: A Mini Review

Psoriasis is a chronic and recurrent immune-related skin disease that often causes disfigurement and disability. Due to the visibility of lesions in patients and inadequate understanding of dermatology knowledge in the general public, patients with psoriasis often suffer from stigma in their daily lives, which has adverse effects on their mental health, quality of life, and therapeutic responses. This review summarized the frequently used questionnaires and scales to evaluate stigmatization in patients with psoriasis, and recent advances on this topic. Feelings of Stigmatization Questionnaire, Questionnaire on Experience with Skin Complaints, and 6-item Stigmatization Scale have been commonly used. The relationship between sociodemographic characteristics, disease-related variables, psychiatric disorders, quality of life, and stigmatization in patients with psoriasis has been thoroughly investigated with these questionnaires. Managing the stigmatization in patients with psoriasis needs cooperation among policymakers, dermatologists, psychologists, psychiatrists, researchers, and patients. Further studies can concentrate more on these existing topics, as well as other topics, including predictors of perceived stigmatization, stigmatization from non-patient groups, influence of biologics on stigmatization, and methods of coping with stigmatization.

Assessment of stigma related to visible skin diseases: a systematic review and evaluation of patient-reported outcome measures

Misconceptions about visible skin diseases are widespread, and patients often face discrimination and stigmatization due to their condition. The associated negative health and psychosocial consequences of stigmatization in skin diseases have prompted an increase in research activity in recent times, resulting in a wide variety of assessment measures. This study aimed at aggregating and evaluating evidence of psychometric properties and methodological quality of published measures to assess stigma in visible skin diseases. Studies assessing stigmatization in visible skin diseases were searched in four databases (Medline, PsycINFO, Web of Science and Embase) until February 2021. The review followed PRISMA guidelines. Papers regarding development and/or validation of measures were identified by two independent researchers. Inclusion criteria were defined as follows: (i) quantitative studies in (ii) populations with skin diseases using (iii) questionnaires explicitly assessing (iv) perceived or public stigmatization or discrimination available in (iv) English or German language. The COnsensus-based Standards of health Measurement INstruments (COSMIN) checklist was used to evaluate their psychometric properties and risk of bias. 35 studies using 21 instruments were identified. Twenty instruments focused on assessing the perceived reality of those affected by visible skin diseases, while public stigma was only assessed by two instruments. Twelve scales could be recommended for use, while nine instruments had the potential to be recommended after further studies have assessed their quality. Some limitations are to be noted. Only studies in English and German were included. Research on self-constructed instruments can lead to new validated instruments, but they were not included in the review at this point. Several validated instruments could be recommended for use. Future research is needed regarding the assessment of stigma across different visible skin diseases, in children and adolescents, and in the general public.

Cytosolic DNA‒Mediated STING-Dependent Inflammation Contributes to the Progression of Psoriasis

Psoriasis is a chronic inflammatory skin disease characterized by an active dynamic interplay between immune cells and keratinocytes (KCs). STING is a universal receptor that recognizes cytosolic DNA and triggers innate immune activation. This study aims to elucidate the role of STING in the inflammation in psoriasis. STING deficiency alleviated psoriatic symptoms and inflammation in mouse models of psoriasis. Stimulation of macrophages with double-stranded DNA induced STING-dependent release of TNF-α and hydrogen peroxide in vitro. Furthermore, incubation of KCs with TNF-α or hydrogen peroxide increased oxidative DNA damage, induced nuclear DNA release into the cytosol, and inhibited double-stranded DNA‒induced degradation of STING protein. More importantly, transfection of KCs with double-stranded DNA synergized with TNF-α or hydrogen peroxide to induce STING-dependent activation of NF-κB and subsequent expression of Il1b, Ccl20, and Cxcl10. Finally, exposure to 5,6-dimethylxanthenone-4-acetic acid (a STING agonist) aggravated psoriatic symptoms and inflammation in wild-type mice but not in STING-deficient mice. Collectively, STING functioned as a self-DNA sensor in macrophages and KCs of psoriatic skin. Cytosolic DNA-induced activation of STING in immune cells and KCs acted synergistically and contributed to the inflammation in psoriasis.

Evaluation of Stigma Toward Individuals With Alopecia

Importance

Perceived stigma among patients with alopecia is associated with impaired quality of life; however, the magnitude of laypersons' stigma toward individuals with alopecia is unknown.

Objective

To determine the prevalence and magnitude of laypersons' stigma toward individuals with varying degrees of alopecia and whether stigma increases with increased severity of alopecia.

Design, Setting, and Participants

This was a cross-sectional study using an internet survey administered to a convenience sample of adult respondents in the US participating on the Amazon Mechanical Turk platform. Portrait images of 6 individuals without hair loss were created using artificial intelligence and stock images. Each portrait was edited to create 2 additional versions, 1 with scalp hair loss and 1 with complete hair loss, for a total of 18 images. On January 9 to 10, 2020, the survey presented each internet respondent with 1 randomly selected portrait to be used in answering a series of stigma-related questions from 3 domains: stereotypes, social distance, and disease-related myths; the third domain was presented only to respondents who believed that the individual pictured had a medical condition.

Main Outcomes and Measures

The main outcome was the prevalence and magnitude of stigma of laypersons toward individuals with alopecia and the percentage of laypersons who believed the individual pictured had a medical condition as recorded in survey responses.

Results

The survey was completed by 2015 respondents (99.9% completion rate) with a mean age of 37 (range, 18-78) years; 1014 (50.3%) were men; 1596 (79.2%) were White; and 1397 (69.3%) had a college or postcollege education. Endorsement of every stigma item increased as alopecia severity increased (2.4%-27.6%). Absolute change on the stereotype (0.5-0.6) and social distance scales (0.2-0.5) also increased, indicating more stigma. The percentage of respondents believing the individual pictured had a medical condition increased as alopecia severity increased (33.6%-75.7%; P < .001). Among the subgroup of respondents who were asked to rate their agreement with disease-related myths, the absolute change on the myth scale decreased as alopecia severity increased, indicating decreased stigma (-0.7 to -1.2).

Conclusions and Relevance

This cross-sectional survey study found that stigmatizing attitudes of laypersons toward patients with alopecia exist across a multitude of social and professional scenarios. Stigma prevalence and magnitude vary by alopecia severity and possibly by whether alopecia is believed to be a medical condition.

Effectiveness of a structured short intervention against stigmatisation in chronic visible skin diseases: Results of a controlled trial in future educators

Background

Chronic visible skin diseases are highly prevalent, and patients affected frequently report feeling stigmatised. Interventions to reduce stigmatisation are rare.

Objectives

This study aimed to evaluate the effectiveness of a structured short intervention in reducing stigmatising attitudes towards psoriasis in future educators.

Methods

The intervention consisted of four components: (1) self‐reflection, (2) education on skin diseases, (3) contact between participants and a person with psoriasis and (4) practising of knowledge via case studies. A quasi‐experimental, pre–post study design was chosen with a nonrandomized contemporaneous control group that attended regular lessons. The main outcomes were participants' desire for social distance, stereotype endorsement, illness‐related misconceptions and intended behaviour. Intervention effects were analysed using mixed repeated‐measures analysis of variance, with Bonferroni post‐hoc tests for pairwise comparisons.

Results

The sample consisted of 221 students attending vocational training as educators (n = 118 intervention group, n = 103 control group). While no effect of the intervention was found in social distance, small to large effect sizes were observed for intended behaviour (r = .14), illness‐related misconceptions (r = .28) and stereotype endorsement (r = .42). The intervention group reported significantly higher satisfaction with the seminar compared to the control group.

Conclusions

Overall, the short intervention was effective at reducing stigmatising attitudes in future educators. In perspective, revised versions could help in reducing stigmatisation in various demographics and promote patient empowerment by acknowledging and including them as experts on their own behalf.

Patient or Public Contribution

Patient advocate groups were consulted and involved in the superordinate destigmatization research programme and intervention.

Molecular Pathogenesis of Psoriasis and Biomarkers Reflecting Disease Activity

Psoriasis is a chronic inflammatory skin disease induced by multifactorial causes and is characterized by bothersome, scaly reddish plaques, especially on frequently chafed body parts, such as extensor sites of the extremities. The latest advances in molecular-targeted therapies using biologics or small-molecule inhibitors help to sufficiently treat even the most severe psoriatic symptoms and the extra cutaneous comorbidities of psoriatic arthritis. The excellent clinical effects of these therapies provide a deeper understanding of the impaired quality of life caused by this disease and the detailed molecular mechanism in which the interleukin (IL)-23/IL-17 axis plays an essential role. To establish standardized therapeutic strategies, biomarkers that define deep remission are indispensable. Several molecules, such as cytokines, chemokines, antimicrobial peptides, and proteinase inhibitors, have been recognized as potent biomarker candidates. In particular, blood protein markers that are repeatedly measurable can be extremely useful in daily clinical practice. Herein, we summarize the molecular mechanism of psoriasis, and we describe the functions and induction mechanisms of these biomarker candidates.

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.

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.

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.

Prevalence of psoriasis and associated risk factors in China: protocol of a nationwide, population-based, cross-sectional study

INTRODUCTION

Psoriasis is a chronic inflammatory skin disease which could lead to serious complications and increased risk of cardiovascular diseases. Psoriasis was recognised as a serious non-communicable disease with important public health impact by member states in the World Health Assembly resolution in 2014. However, data on psoriasis epidemiology are scarce worldwide, especially from low-income and middle-income countries. Only a few epidemiological studies on psoriasis have been conducted in parts of China, mostly without appropriate sampling design and data analysis.

AIM

This study aims to obtain the prevalence of psoriasis in China and relevant risk factors through a nationwide, population-based study with adequate statistical design.

METHODS AND ANALYSIS

This is a cross-sectional study to be conducted in 60 sites across China. A multistage, cluster random sampling design is used. Participants should have local household registration or be residing in the survey area for at least 6 months during the past year. The presence of psoriasis is ascertained independently by two certified dermatologists. If any discrepancies in the diagnosis occur, consensus will be met via discussion. All participants will be interviewed with a questionnaire to collect sociodemographic and disease information. The field survey will be implemented from October 2018 to June 2019. All statistical analyses will be conducted using survey procedures in SAS V.9.2 software to adjust for the complex sample design.

ETHICS AND DISSEMINATION

The study has been reviewed and approved by the ethics committee of the Institute of Dermatology, Chinese Academy of Medical Sciences and Peking Union Medical College (Nanjing, China). A written informed consent will be obtained from all participants before the questionnaire survey. Findings of the study will be disseminated through publications in peer-reviewed journals.
