The Sense of Stigmatization in Patients with Plaque Psoriasis

Effectiveness, safety and impact of guselkumab on sexuality and perceived stigmatization in patients with psoriasis in routine clinical practice: Week 28 results from the prospective German multicentre G-EPOSS study

BACKGROUND

G-EPOSS is a prospective, non-interventional, German multicentre study of patients with moderate-to-severe plaque psoriasis receiving guselkumab, a therapeutic monoclonal antibody targeting interleukin-23, in a real-world setting.

OBJECTIVES

The objective of the study was to evaluate the effectiveness and safety of guselkumab, including its impact on skin, health-related quality of life (HRQoL), sexuality, and perceived stigmatization.

METHODS

Patients (≥18 years old) received guselkumab per routine clinical practice. The primary endpoint was the proportion of patients achieving absolute Psoriasis Area and Severity Index (PASI) ≤ 3 at Week (W)28. Secondary endpoint assessments over 28 weeks included the Nail Psoriasis Severity Index (NAPSI), anogenital Physician's Global Assessment (aPGA), and Dermatology Life Quality Index (DLQI). Sexuality and perceived stigmatization were assessed by patients using the Relationship and Sexuality Scale (RSS) and Perceived Stigmatization Questionnaire (PSQ), respectively.

RESULTS

Overall, 293 patients were included in the evaluable set population. Mean age and disease duration were 45.6 and 17.6 years, respectively. At baseline, mean PASI, aPGA and DLQI scores were 15.3, 2.7 and 11.3, respectively. In total, 25.9% of patients had received a prior biologic. Overall, 83.0% of patients achieved PASI ≤ 3, and 56.2%/35.1% achieved PASI ≤ 1/PASI = 0, respectively, at W28. Among those with NAPSI ≥ 1 and aPGA ≥ 1 at baseline, NAPSI = 0 and aPGA = 0 were achieved by 39.2% and 61.1% of patients, respectively, and 61.4% of patients achieved DLQI 0-1 at W28. Improvements were observed over 28 weeks across individual items of the DLQI, RSS and PSQ, indicating improved HRQoL and sex life, and decreased perceived stigmatization. Based on DLQI Question (Q)9, 53.6% of patients experienced sexual difficulties at baseline, which decreased to 12.1% at W28. DLQI Q9 responses were consistent with RSS item responses, highlighting DLQI Q9 as a sentinel for sexual impairment.

CONCLUSIONS

Guselkumab improved overall skin symptoms and HRQoL in patients with psoriasis and decreased sexual impairment and perceived stigmatization. No new safety signals were observed.

Australian consensus: Treatment goals for moderate to severe psoriasis in the era of targeted therapies - Adult patients

BACKGROUND

Over the last decade, the treatment landscape for moderate-severe psoriasis has rapidly evolved. The Australasian College of Dermatologists sought to review and update previously published treatment goals for moderate-severe psoriasis.

METHODS

A modified Delphi approach was used. Comprehensive literature review and guideline evaluation resulted in the development of statements and other questions to establish current clinical practices. Two rounds of anonymous voting were undertaken, with a collaborative meeting held in between to discuss areas of discordance. Overall, consensus was defined as achievement of ≥75% agreement in the range 7-9 on a 9-point scale (1 strongly disagree; 9 strongly agree).

RESULTS

Consensus was achieved on 26/29 statements in round 1 and a further 20 statements in round 2. There was strong agreement to expanding the classification/definition of psoriasis severity by including a choice of metrics, incorporating quality of life measures, and widening the scope of high-impact sites. Consensus was also reached on revised treatment response criteria, which were then incorporated into a new treatment algorithm. There was discordance with the current requirement to undertake a trial with established systemic agents before accessing targeted therapy.

CONCLUSION

The ability of new targeted treatment options to change the narrative in psoriasis patient care can only be properly realised if challenges to timely and equitable access are addressed. The proposed framework for the assessment, classification and management of moderate-severe psoriasis aligns with international recommendations. Its adoption into Australian clinical practice is hoped to improve treatment outcomes and patients' satisfaction with their care.

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.

Measuring public attitudes towards people living with chronic diseases in Arabic-speaking populations: adaptation and development of the Social Stigma Scale of Chronic Diseases (SSS-CD)

BACKGROUND

A large proportion of the population in Arab countries suffer from chronic diseases. According to the statistics by the Global Health Estimates, chronic illnesses contribute by 71% to total deaths in the Arab region. While chronic illnesses have been demonstrated to carry high levels of social stigma, it is only recently that little research attention has been given to this topic in the Arab world. It is well-established that the social stigma construct is culturally-dependent. Therefore, the lack of an Arabic measure highlighted the urgent need for developing a culturally adapted and valid instrument to assess social stigma toward people living with chronic diseases. In this study, we aimed to examine the psychometric properties of the Arabic translation, adaptation and development of "the Social Stigma Scale of Chronic Diseases" (SSS-CD).

METHOD

Fifteen items derived from the literature and assessing social stigma towards chronic diseases have been administered to 570 Arabic-speaking adults from the Lebanese general population (aged 24.59 ± 6.75years; 68.6% women). Items were translated into Arabic using a forward-backward translation method. Exploratory factor analysis (EFA) using a principal-axis EFA on the first split-half subsample, followed by a confirmatory factor analysis (CFA) tested on the model extracted from the EFA on the second split-half subsample, were conducted to examine the construct validity of the SSS-CD. Fit indices were deemed adequate if the normed model chi-square (χ²/df) ≤ 3, the Steiger-Lind root mean square error of approximation (RMSEA) ≤ 0.08, the Tucker-Lewis Index (TLI) and the comparative fit index (CFI) ≥ 0.90.

RESULTS

Findings revealed that the 10-item SSS-CD has a unidimensional factor structure, with the following fit indices: χ²/df = 92.95/34 = 2.73, RMSEA = 0.077 (90% CI 0.059, 0.096), SRMR = 0.062, CFI = 0.939, TLI = 0.919. A good internal consistency was demonstrated by a McDonald's omega value of 0.73 for the total score. Findings also supported invariance across gender, with men exhibiting higher levels of social stigma attached to chronic diseases than women. All three dimensions of stigmatization (social, psychological and evolutionary stigmatization) were positively correlated with SSS-CD scores (Social self-interest [r = .40; p < .001], Evolutionary self-interest [r = .37; p < .001], Psychological self-interest [r = .42; p < .001]), demonstrating relatively strong convergent validity.

CONCLUSION

Our findings suggest that the SSS-CD has robust psychometric qualities. We thus preliminarily suggest that the scale is valid, reliable and suitable for use among Arabic-speaking people from the general population to measure public attitudes towards people living with chronic diseases. Providing this psychometrically sound measure will hopefully enable to foster research in this area in order to draw a clear overview of the prevalence and characteristics of social stigma attached to chronic diseases in Arabic-speaking communities. However, given that this was the first study to examine the psychometric properties of the SSS-CD, the present findings and conclusions should be considered tentative pending future cross-national validation studies.

Sexual Dysfunction in Women and Men with Psoriasis: A Cross-Sectional Questionnaire-Based Study

Background and objectives: Psoriasis can lead to feelings of stigmatization, hinder social functioning, and impair quality of life. Psoriasis can also affect sexual activity, but there is still little research on this topic. The present study investigated whether and to what extent psoriasis, its severity, location and extent of skin lesions affect sexual dysfunction. Materials and Methods: A total of 45 women and 64 men aged 18 to 73 years hospitalized for psoriasis exacerbations were included in the study. Psoriasis severity, as assessed by the Psoriasis Area and Severity Index (PASI), ranged from 0.2 to 65 points (mean: 17.0 ± 14.9 points). After collecting demographic and clinical data, each subject was asked to complete the Dermatology Life Quality Index, the 11-item Sexual Life Questionnaire and the International Index of Erectile Function (only men). Results: Our study found that more than 90% of the patients surveyed felt at least a slight unattractiveness due to psoriasis. In approximately 80% of the subjects, the skin lesions at least occasionally affected their sex life, and more than 50% at least sometimes avoided sexual contact. The location of psoriasis, particularly in the genital area (p = 0.01), on the face (p = 0.03) and hands (p = 0.05), also had a significant impact on the level of sexual problems. Psoriasis has a significant impact on the quality of life (QoL), and a deterioration in QoL was strongly correlated with sexual dysfunction (r = 0.6, p < 0.001), PASI scores (r = 0.36, p < 0.001), self-assessment of psoriasis severity and location of psoriatic lesions. Conclusions: Psoriasis leads to various limitations, especially in the sphere of sexual life. Patients with psoriasis feel stigmatized, have lowered self-esteem and consequently experience significant sexual problems. Awareness of the co-occurring psychological aspect of psoriasis and the routine use of validated scales in dermatology practice should contribute to the rapid identification of patients with sexual dysfunction.

The Implication of Misinformation and Stigma in Age-Related Quality of Life, Depression, and Coping Mechanisms of Adult Patients with Psoriasis

Background and Objectives: Stigma and lack of acceptance in society might have detrimental effects on the quality of life of patients with psoriasis, sometimes being comparable with other chronic diseases and conditions that affect the appearance of a patient, such as burns. Therefore, we surveyed our patients diagnosed with psoriasis to determine the implications of misinformation and stigma for their quality of life, depression, and coping strategies stratified by different age categories. Materials and Methods: A cross-sectional study was designed for a sample size of a minimum of 45 patients considering a prevalence of psoriasis of 2–3% in the general population. The study participants (patients and controls) were given both a paper-based unstandardized questionnaire and an online version of three standardized surveys. The cohort of patients was further split into three age groups to determine their age-related quality of life and coping mechanisms. Results: The proportion of patients with a history of depression and depressive symptoms among patients with psoriasis was significantly higher. Multiple discrepancies were observed between patients and controls regarding questions that targeted stigma and misinformation. On the Coping Orientation to Problems Experienced Inventory (COPE-60) questionnaire, older patients were more likely to use positive coping mechanisms such as engagement and problem-focused coping, while the young patients were using more emotion-focused coping mechanisms. However, patients in the 30–50 age range group scored the highest on physical and mental health among all participants who filled the 12-Item Short Form Survey (SF-12) survey. The Dermatology Life Quality Index (DLQI) results showed significantly more patients answering “a lot and very much” concerning embarrassment and social activities, while sexual difficulties affected the older patients. The strongest correlations with depression were observed in the young patient group, who believed that psoriasis can cause skin cancer (rho = 0.418) and who had sexual difficulties (rho = 0.414) and embarrassment (rho = 0.359) as evaluated by the DLQI survey. In the 30- to 50-year-old group, the strongest correlations were with the feeling of being stigmatized (rho = 0.376), having sexual difficulties (rho = 0.367) and disengagement coping style (rho = 273). Conclusions: While the respondents are reasonably well-informed regarding psoriasis, a degree of stigma remains, likely due to involuntary emotional responses such as repulsion and embarrassment. It is essential to establish initiatives aimed at educating the general public, raising awareness, and establishing a more tolerant social environment for psoriasis patients.

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.

Epidemiology of psoriasis in the Russian Federation according to the patient registry

Background. Psoriasis is a chronic skin disorder that impairs patients health-related quality of life. It is associated with patients need in specialized medical care and with essential medical costs. Psoriasis may be the reason for temporary or permanent disability. Patient registries are important sources of epidemiological and clinical data on patients with psoriasis and medical care provided. Aims. To describe demographic characteristics, characteristics of the disease, prevalence of concomitant and past diseases in adult (18 years and older) patients with moderate and severe psoriasis included in the patient registry of the Russian Society of Dermatovenereologists and Cosmetologists. Materials and methods. The data of 3,268 patients with psoriasis aged 18 years and older were analyzed as of inclusion in the registry. Data lock point was June 3, 2021. Descriptive statistics methods were applied in data analysis. Results. The mean ( SD) age of adult patients at inclusion in the registry was 46.1 14.4 years. Male patients accounted for 60.5%. The mean age of onset of psoriasis is 31.1 16.1 years. Most of the patients (89.5%) have psoriasis vulgaris. The mean body surface area at inclusion was 43.3% 24.7%. 28.9% of patients had psoriatic arthritis at inclusion in the registry. A high prevalence of cardiovascular diseases was revealed: arterial hypertension 28.5%, coronary heart disease 5.4%, myocardial infarction and acute cerebrovascular accident 0.9% each. More than half of patients are pre-obese or obese according to the WHO body mass index classification. 2.2% of patients have impaired glucose tolerance, 6.7% of patients have type 2 diabetes mellitus. 3.8% of patients have diseases or dysfunction of the thyroid gland. The prevalence of diseases of the digestive system is high: any disease of the esophagus, stomach and duodenum was noted in 10.2% of patients, any disease of the liver, gallbladder, biliary tract and pancreas in 11.8% of patients. The prevalence of viral hepatitis C among patients with psoriasis was 2.6%. Conclusions. The prevalence of comorbidities is high among Russian patients with moderate and severe psoriasis.
