Defining well-being in psoriasis: A Delphi consensus among healthcare professionals and patients.

Psoriasis is a chronic skin disease that negatively impacts on patient's life. A holistic approach integrating well-being assessment could improve disease management. Since a consensus definition of well-being in psoriasis is not available, we aim to achieve a multidisciplinary consensus on well-being definition and its components. A literature review and consultation with psoriasis patients facilitated the design of a two-round Delphi questionnaire targeting healthcare professionals and psoriasis patients. A total of 261 panellists (65.1% patients with psoriasis, 34.9% healthcare professionals) agreed on the dimensions and components that should integrate the concept of well-being: emotional dimension (78.9%) [stress (83.9%), mood disturbance (85.1%), body image (83.9%), stigma/shame (75.1%), self-esteem (77.4%) and coping/resilience (81.2%)], physical dimension (82.0%) [sleep quality (81.6%), pain/discomfort (80.8%), itching (83.5%), extracutaneous manifestations (82.8%), lesions in visible areas (84.3%), lesions in functional areas (85.8%), and sex life (78.2%)], social dimension (79.5%) [social relationships (80.8%), leisure/recreational activities (80.3%), support from family/friends (76.6%) and work/academic life (76.5%)], and satisfaction with disease management (78.5%) [treatment (78.2%), information received (75.6%) and medical care provided by the dermatologist (80.1%)]. This well-being definition reflects patients' needs and concerns. Therefore, addressing them in psoriasis will optimise management, contributing to better outcomes and restoring normalcy to the patient's life.

The association between periodontitis and the impact of oral health on the quality of life of individuals with psoriasis and psoriatic arthritis.

OBJECTIVE: To evaluate the association between psoriasis (PSO), psoriatic arthritis (PsA) and periodontitis (PE), and the Oral Health-Related Quality of Life (OHRQoL) impacts on individuals with psoriatic disease's daily activities compared to the non-psoriatic ones. MATERIALS & METHODS: 296 individuals with psoriatic disease (PSO n = 210, APS n = 86) (cases) and 359 without these diseases (controls) were included. Complete periodontal examinations and collection of variables of interest were performed. The Brazilian version of the Oral Impacts on Daily Performance (OIDP) instrument was applied. RESULTS: The prevalence of PE was higher in PsA (57.0%; OR = 2.67 95%CI 1.65-4.32; p<0.001) than in PSO (34.3%; OR = 1.05 95% CI 0.73-1.51; p<0.001) compared to controls (33.1%). Both PsA and PSO groups showed more sites and teeth with 4-6mm probing depth (PD) and had higher OIDP scores than controls (p<0.001), thus indicating worse self-reported quality of life. PE, PSO+PE and consumption of alcohol/anxiolytics significantly influenced OHRQoL (p<0.05). The influence of periodontal parameters on OHRQoL was observed for the presence of PE; PD >6 mm; clinical attachment level >6 mm; higher plaque index, % sites and teeth with bleeding on probing (p<0.05). CONCLUSION: Negative impacts of PE on the OHRQoL were demonstrated. The ones having PSO and especially PsA and PE presented significantly worse indicators.

Disease severity, treatment patterns, and quality of life in patients with moderate-to-severe psoriasis routinely managed with systemic treatment: results of the CRYSTAL observational study in Central and Eastern European countries.

Psoriasis is a common, life-long skin disease with a significant negative health and societal impact. Data on rates of disease control and treatment strategies are lacking in Central and Eastern European countries. We aimed to describe the real-world disease severity, control, and treatment strategies for psoriasis in patients from Central and Eastern European countries. CRYSTAL (EUPAS36459) was a cross-sectional, retrospective study in adults (18-75 years) from Bulgaria, Estonia, Hungary, Latvia, Lithuania, Romania, and Russia. We enrolled patients with moderate-to-severe psoriasis receiving continuous systemic treatment for ≥24 weeks. We used the Psoriasis Area and Severity Index (PASI) to describe disease severity and the Dermatology Life Quality Index (DLQI) to assess quality of life (QoL) and collected other outcomes [psoriasis work productivity and activity impairment (WPAI-PSO), patient satisfaction] at enrollment. Analyses were descriptive. A total of 690 patients were included in the analyses. Median disease duration was 11.8 years. Current treatment was monotherapy for most patients (95.8%) with either biological (BIO group; 88.4%) or conventional (NON-BIO group; 7.4%) agents. Mean (± standard deviation) absolute PASI scores were 3.5 ± 5.7, 3.1 ± 5.3, and 6.6 ± 7.4 in the overall population, the BIO group, and the NON-BIO group, respectively. Among patients treated with monotherapy, absolute PASI scores ≤1, ≤3, and ≤5 were observed for 44.1%, 72.0%, and 82.6% of BIO patients and 21.6%, 33.3%, and 49.0% of NON-BIO patients. Mean DLQI total score was 3.3 ± 5.1; higher scores were noted for higher absolute PASI. The most impacted WPAI-PSO domain was presenteeism; for all domains, impact increased with increased absolute PASI. A total of 91.8% of BIO patients and 74.5% of NON-BIO patients were satisfied with the current treatment. We observed a better disease control in BIO than NON-BIO patients. However, around half of BIO patients did not reach clear skin status and reported an impact on QoL. An improvement in treatment strategies is still needed in Central and Eastern European countries to optimize outcomes of moderate-to-severe psoriasis.

Validation and application of the Dermatology Life Quality Index score, a modification of the DLQI score, in psoriasis patients.

BACKGROUND: All the scoring methods for the DLQI miss the moderate impact of the disease on patients, which may underestimate the impact of psoriasis on patients' quality of life. To improve the accuracy of the assessment of the Dermatology Life Quality Index score (DLQI) for patients with psoriasis, this study proposed and validated a new scoring method, the DLQI-NS, which includes the moderate impact option in the self-assessment of each item in psoriasis patients. METHODS: A cross-sectional study was conducted in which patients with psoriasis were enrolled. A total of 425 participants completed the DLQI, DLQI-NS and Skindex-16 questionnaires. Reliability, validity, ceiling and floor effects were evaluated of both DLQI and DLQI-NS questionnaires. RESULTS: About 14.4-32.5% of the patients reported a moderate impact on quality of life. The DLQI-NS allowed 17 more patients (4.0%) to achieve severe disease. The Cronbach's alpha coefficient of the DLQI-NS was 0.90, and that of the DLQI was 0.89. The KMO test results for the DLQI-NS and DLQI were 0.927 and 0.916, respectively. One factor was identified for each questionnaire. The items of the DLQI-NS showed an item-total correlation from 0.52 to 0.82, and the DLQI questionnaire's item-total correlation ranged from 0.47 to 0.83. The DLQI-NS, DLQI total score and Skindex-16 had Spearman's rank correlation coefficients of 0.89 and 0.84, respectively. Both the DLQI-NS and DLQI showed significant moderate correlations with the BSA (0.51 vs. 0.50) and PASI (0.47 vs. 0.46). No ceiling effects were observed for any of the items of both questionnaires. CONCLUSION: The validity and reliability of the DLQI-NS and DLQI were good, but the DLQI-NS was superior to the DLQI. The DLQI-NS is an effective self-assessment tool for assessing quality of life in psoriasis patients.

Neuroticism and inflammatory skin diseases: a bidirectional Mendelian randomization study.

Previous observational studies have linked inflammatory skin diseases with mental health issues and neuroticism. However, the specific impact of neuroticism and its subclusters (i.e. worry, depressed affect, and sensitivity to environmental stress and adversity) on these conditions remains underexplored. In this work, we explored causal associations between common inflammatory skin diseases and neuroticism. We conducted a two-sample, bidirectional Mendelian randomization (MR) analysis using data from genome-wide association studies in psoriasis, atopic dermatitis, neuroticism and relevant genetic subclusters conducted on participants of European ancestry. Corrections for sample overlap were applied where necessary. We found that psoriasis was causally associated with increased levels of worry (odds ratio, 95% confidence intervals: 1.011, 1.006-1.016, P = 3.84 × 10-6) while none of the neuroticism subclusters showed significant association with psoriasis. Sensitivity analyses revealed considerable evidence of directional pleiotropy between psoriasis and neuroticism traits. Conversely, genetic liability to atopic dermatitis did not exhibit any significant association with neuroticism traits. Notably, genetically predicted worry was linked to an elevated risk of atopic dermatitis (odds ratio, 95% confidence intervals: 1.227, 1.067-1.41, P = 3.97 × 10-3). Correction for overlapping samples confirmed the robustness of these results. These findings suggest potential avenues for future interventions aimed at reducing stress and worry among patients with inflammatory skin conditions.

Health-related quality of life in patients with generalized pustular psoriasis - a Swedish register study.

BACKGROUND: Real-world data on health-related quality of life (HRQoL) in generalized pustular psoriasis (GPP) are scarce and studies have been restricted in terms of instruments used for assessments. OBJECTIVE: To assess generic and dermatology-specific HRQoL of patients with GPP compared with patients with plaque psoriasis using real-world data from the Swedish National Register for Systemic Treatment of Psoriasis. METHODS: Cross-sectional data from 2006 to 2021 including 7041 individuals with plaque psoriasis without GPP and 80 patients with GPP, of which 19% also had plaque psoriasis. Total scores for the EuroQol-5 Dimensions (EQ-5D) and Dermatology Life Quality Index (DLQI), as well as degree of severity within the instruments' dimensions/questions, were compared between patient groups. RESULTS: EQ-5D scores were significantly (p < .01) lower (worse) in patients with GPP (mean [standard deviation (SD)] 0.613 [0.346]) vs. patients with plaque psoriasis (mean [SD] 0.715 [0.274]), indicating lower generic HRQoL of patients with GPP. Significantly (p < .01) higher (worse) total DLQI scores were observed for patients with GPP (mean [SD] 10.6 [8.9]) compared with patients with plaque psoriasis (mean [SD] 7.7 [7.1]), with proportionally more patients with GPP having severe (20% vs. 16%) and very severe (17% vs. 8%) problems. The worsened scores for GPP vs. plaque psoriasis were consistent across EQ-5D dimensions and DLQI questions. CONCLUSIONS: Individuals with GPP have a considerable impairment in both generic and dermatology-specific HRQoL. The HRQoL was significantly worse in individuals with GPP compared to individuals with plaque psoriasis. The significant HRQoL impairment of GPP shows the potential value of better healthcare interventions for this multisystem disease.

The study assessed health-related quality of life (HRQoL) in patients with generalized pustular psoriasis (GPP) compared to patients with plaque psoriasis using real-world data from the Swedish National Register for Systemic Treatment of Psoriasis.The results showed significantly worse HRQoL scores by two different HRQoL instruments (EuroQol-5 Dimensions [EQ-5D] and Dermatology Life Quality Index [DLQI]) in patients with GPP compared to patients with plaque psoriasis.The study indicates that individuals with GPP have a considerable impairment in both generic and dermatology-specific HRQoL.

Roles of negative emotions and personality traits in psoriasis vulgaris: A mendelian randomization study.

BACKGROUND: Many studies have indicated that negative emotions and personality traits are related to psoriasis, though few have provided causal evidence. METHODS: Our analysis utilized 15 genome-wide association study datasets to identify instrumental variables associated with negative emotions, personality traits and psoriasis vulgaris. Two-sample Mendelian randomization was conducted to identify the causal associations of negative emotions and personality traits with psoriasis vulgaris. To mitigate bias from multiple tests, we adjusted p-values using the Benjamini-Hochberg method. RESULTS: Our study revealed causal links between negative emotions and psoriasis vulgaris, including depressed affect, worry too long, feeling hurt, guilty feelings, mood swings, unenthusiasm, miserableness, fed-up feelings. However, there was no significant evidence of a causal relationship between feeling lonely and psoriasis vulgaris. Additionally, personality traits including neuroticism and openness to experience were found to have causal effects on psoriasis vulgaris. However, no significant evidence supported a causal relationship between agreeableness, conscientiousness, and extraversion with psoriasis vulgaris. CONCLUSION: Our findings suggest that experiencing negative emotions including depressed affect, worrying excessively, feeling hurt, guilty feelings, mood swings, lack of enthusiasm, miserableness and fed-up feelings may pose risks for psoriasis vulgaris. Additionally, neuroticism is associated with a risk of psoriasis vulgaris. Conversely, the openness trait may serve a protective role against psoriasis vulgaris.

Shared decision-making in psoriasis care: Evaluation of how patients' perception of clinicians' delivery of care changes by age and sex.

BACKGROUND: Shared decision-making (SDM) refers to a collaborative process in which clinicians assist patients in making medically informed, evidence-based decisions that align with their values and preferences. There is a paucity of literature on SDM in dermatology. OBJECTIVE: We aim to assess whether male and female psoriasis patients evaluate their clinicians' engagement in SDM differently across different age groups. METHODS: Cross-sectional study using data from the 2014-2017 and 2019 Medical Expenditure Panel Surveys (MEPS). RESULTS: A weighted total of 7,795,608 psoriasis patients were identified. SDM Scores ranged from 1 to 4, with 4 representing the most favorable patient evaluation of their clinicians' engagement in SDM. We conducted multivariate linear regression to compare mean SDM Scores in male psoriasis patients versus female psoriasis patients across different patient age groups. Female patients ages 60-69 perceived significantly greater clinician engagement in SDM compared to age-matched male patients (female patient perception of SDM 3.65 [95%CI:3.61-3.69] vs. male patient perception of SDM 3.50 [95%CI:3.43-3.58], p<0.005). The same trend of older female patients evaluating their clinicians' engagement in SDM significantly higher than their age-matched male counterparts exists for the age group >70 (p<0.005). No significant differences between male and female patients' evaluations of their clinicians' engagement in SDM were demonstrated in subjects younger than 60. All calculations were adjusted for demographic and clinical factors. CONCLUSIONS: Compared to older male psoriasis patients, older female psoriasis patients evaluated their clinicians to be more engaged in shared decision-making.

Psoriasis and mental health in adolescents: A cross-sectional study within the Danish National Birth Cohort.

BACKGROUND: Psoriasis is a chronic skin disease associated with lower quality of life and higher risk of anxiety and depression in adults. We investigate whether adolescents with psoriasis also experience poorer mental health than their peers. METHODS: In this cross-sectional study, we included questionnaire data on psoriasis and mental health from the 18-year follow-up of the Danish National Birth Cohort. We estimated odds ratios (OR) and 95 % confidence intervals (CI) using a logistic regression with inverse probability weighting to account for potential selection bias, adjusted for potential confounders identified a priori. We estimated associations between self-reported psoriasis and multiple aspects of mental health (self-rated health, life satisfaction, mental well-being, loneliness, overall and internalizing behavioral difficulties, depressive symptoms, and anxiety symptoms). In sensitivity analyses, we examined doctor-diagnosed psoriasis and psoriasis with and without joint pain. RESULTS: Of the 44,838 included in this study, 1147 (2.6 %) reported psoriasis. Adolescents with psoriasis had a higher risk of nearly all outcomes, including depressive symptoms (OR 1.38; 1.19-1.58) and panic/agoraphobia among both males (OR 1.72; 1.33-2.19) and females (OR 1.60; 1.33-1.92). Associations attenuated when restricted to doctor-diagnosed psoriasis. Associations with poor mental health were mainly observed for adolescents with psoriasis also reporting joint pain. LIMITATIONS: We could not establish temporality and lacked data on joint pain in referents. CONCLUSION: Psoriasis is associated with poor mental health in adolescents. This appears to be driven by adolescents with psoriasis also reporting joint pain and is less evident in those with a doctor-confirmed diagnosis.

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.

Experience and caring needs of patients with psoriasis: A qualitative meta-synthesis.

BACKGROUND: As a chronic skin disease, psoriasis often affects the physical, psychological and social status of the patient, which in turn impacts on their experience of illness and needs. However, there is no review of qualitative research that integrates and analyses the experiences and needs of these three influences from a holistic perspective. METHODS: This review follows the ENTREQ guidelines. Six English databases (JBI, Cochrane Library, PubMed, PsyINFO, CINAHL and Embase) and three Chinese databases (CNKI, VIP and Wanfang) were searched from January 2012 to October 2022. Literature was included if it was relevant to the experience of illness and caring needs of patients with psoriasis. The JBI-QARI was used to rate the quality of included studies. RESULTS: Eleven studies were included in the meta-synthesis. Four analytical themes were identified for analysis: physical challenges, psychological discomfort, social phenomena and caring needs. CONCLUSIONS: The combined physical, psychological and social effects of psoriasis and the consequent caring needs should be emphasised. Health professionals, including doctors and nurses, should be aware of the multiple changes in patients and their coping strategies, provide information about psoriasis, monitor and follow-up regularly over time and obtain feedback to inform further treatment and care so as to develop high-quality therapeutic interventions to help and guide patients with their coping strategies. RELEVANCE TO CLINICAL PRACTICE: These findings describe the physical, psychological and social experiences of illness and caring needs of patients with psoriasis. Healthcare professionals should be more aware of patients' easily overlooked psychological and social distress, providing prompt attention and recognition of patients' experiences and needs, offering relevant assistance and support and enhancing daily, regular follow-up to help them improve their understanding of and ability to manage their illness. NO PATIENT OR PUBLIC CONTRIBUTION: This is a meta-synthesis without direct patient involvement.

The patient's perspective on the burden of psoriasis: findings based on the ROCQ, an online survey.

Psoriasis is a common chronic skin disease, with well-characterised impact on quality-of life, however, no information is available on the lifetime impact of psoriasis on patients' lives. This descriptive cross-sectional web-based survey of patients with psoriasis, recruited from an online patient community, was conducted in France in 2021. Established questionnaires (Major Life-Changing Decision Profile-MLCDP, Dermatology Life Quality Index-DLQI, Hospital Anxiety and Depression Scale [HADS]), CAGE and BRIEF-COPE) were administered together with specially created questions. In total, 301 adult patients (mean age: 46.9 years; 56% women; mean disease duration: 20.3 years) participated in the study. The MLCDP showed that a mean of 9.4 life-changing decision items were affected; the most frequently cited domains being social life (n=258; 85.7%) and physical activity (n=226; 75.1%). In addition, 183 participants (60.7%) declared at least moderate impact of their psoriasis on their quality of life (score ≥6), with a median DLQI score of 7 [IQR: 3-13]. Impact on activities of daily living, such as social life, physical activities and marital relationships, was reported by over 50% of participants. Moreover, 107 (35.5%) declared being satisfied and 66 (21.9%) very satisfied with care. Over 50% of participants reported stigma related to being considered to have a contagious disease (n=182) or being unhygienic (n=163) and undesirable (n=167). Finally, 104 participants (34.6%) presented with clinically relevant anxiety and 32 (10.6%) clinically relevant depression (score ≥11) based on the HADS. Psoriasis carries a high psychological burden and has a strong long-term impact on social functioning.

Mental health outcomes in patients with moderate to severe psoriasis treated with bimekizumab: Analysis of phase 2/3 randomized trials.

BACKGROUND: Patients with psoriasis have increased risk of suicidal ideation and behavior (SIB) and depression. Bimekizumab, a biologic that inhibits interleukin (IL)-17A and IL-17F, received Food and Drug Administration approval in 2023 for moderate to severe plaque psoriasis, following 2021 European Medicines Agency approval. OBJECTIVE: To report SIB and depression in patients with moderate to severe psoriasis treated in bimekizumab clinical trials. METHODS: Mental health changes, including neuropsychiatric events, were actively monitored across 9 bimekizumab clinical trials in psoriasis phase 2/3 trials. The patient-reported electronic Columbia-Suicide Severity Rating Scale (measuring SIB) and Patient Health Questionnaire-9 (measuring depression) were administered, monitored by an independent Neuropsychiatric Adjudication Committee. RESULTS: Throughout 7166 patient-years (PY) of bimekizumab exposure, the adjudicated SIB rate was 0.13/100PY; SIB ranges for the general psoriasis population and patients receiving anti-IL-17A/anti-IL-23 therapies are 0.09 to 0.54/100PY and 0.09 to 0.19/100PY, respectively. At week 16, 92.9% vs 81.1% of bimekizumab- vs placebo-treated patients had no/minimal depression. Newonset positive electronic Columbia-Suicide Severity Rating Scale responses and mean Patient Health Questionnaire-9 scores were low for bimekizumab-treated patients. LIMITATIONS: Patient exclusion for significant/severe prespecified SIB/depression history. CONCLUSION: The long-term adjudicated SIB rate with bimekizumab was low and within ranges reported in the general psoriasis patient population and psoriasis patients treated with anti-IL-17A/anti-IL-23 biologics. Screening/monitoring questionnaires reported low SIB and depression levels.

Patients' testimonies, feelings, complaints and emotional experiences with dermatoses on open social media: The French infodemiologic patient's free speech study.

BACKGROUND: Dermatoses represent a significant burden. Patients and their caregivers can turn to social media and digital communities to exchange with each other. These public exchanges constitute real-life data that can be analysed to better understand the patients' feelings and expectations, and the daily difficulties encountered. OBJECTIVE: An infodemiologic study of public testimonies of patients and caregivers related to five dermatoses: eczema, rosacea, vitiligo, acne and psoriasis, over a 3-year time frame (September 2018 to September 2021) in France. To identify main topics of discussion, encountered difficulties and unmet medical needs. METHODS: Data extraction was performed based on a list of pertinent keywords. Web-users' profiles were determined by a specifically trained machine learning algorithm. Encountered difficulties were identified by manual annotation based on a standardized search grid. Co-occurrence analysis of difficulties allowed contextualization of challenges and unmet needs for each dermatosis. RESULTS: A total of 20,282 messages coming from 16,800 web users was extracted. The main topics of discussion were 'Impact on self- image and self-confidence' (23.6%), 'Generic discussion about therapeutics' (23.3%) and 'Burden of others' gaze' (12.8%). The top three mentioned difficulties for the five targeted dermatoses were similar and focused on 'Fear of/and management of symptoms', 'Impact on/and mood management' and 'Damaged self-image'. CONCLUSION: This infodemiologic study highlighted the real-life management of five skin diseases by patients and their caregivers, who turned to social networks to openly express their suffering and seek solutions. The joined analysis of the five diseases enabled a common comprehension of what it is to live with a skin disease, from a patient-centric point of view. The specific analysis of each patient group objectified specific challenges, and main unmet medical needs.

Patient-Reported Outcome Measures for Health-Related Quality of Life in Patients With Psoriasis: A Systematic Review.

Importance: Multiple patient-reported outcome measures (PROMs) for health-related quality of life (HRQL) exist for patients with psoriasis. Evidence for the content validity and other measurement properties of these PROMs is critical to determine which HRQL PROMs could be recommended for use. Objective: To systematically review the validity of HRQL-focused PROMs used in patients with psoriasis. Evidence Review: Using PubMed and Embase, full-text articles published in English or Spanish on development or validation studies for psoriasis-specific, dermatology-specific, or generic HRQL PROMs were included. Development studies included original development studies, even if not studied in psoriasis patients per Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) recommendations. If a study included multiple diagnoses, more than 50% of patients had to have psoriasis or psoriasis-specific subgroup analyses available. Data extraction and analysis followed the COSMIN guidelines. Two independent reviewers extracted and analyzed the data, including PROM characteristics, quality of measurement properties (structural validity, internal consistency, cross-cultural validity, reliability, measurement error, criterion validity, construct validity, and responsiveness), and level of evidence. PROMs were classified into 3 levels of recommendations: (1) PROM recommended for use; (2) PROM requires further validation; and (3) PROM not recommended for use. Findings: Overall, 97 articles were identified for extraction. This included 19 psoriasis-specific, 8 skin-specific, and 6 generic PROMs. According to COSMIN standards, most measures identified received a B recommendation for use, indicating their potential but requiring further validation. Only the Rasch reduced version of the Impact of Psoriasis Questionnaire (IPSO-11 Rasch) received an A recommendation for use given that it had sufficient content validity, structural validity, and internal consistency. Conclusions and Relevance: This study identified a significant lack of information concerning the quality of HRQL measures in psoriasis. This gap in knowledge can be attributed to the fact that traditional measures were developed using validation criteria that differ from the current standards in use. Consequently, additional validation studies in accordance with contemporary standards will be useful in aiding researchers and clinicians in determining the most suitable measure for assessing HRQL in patients with psoriasis.

Sexual functioning in patients with psoriasis: the role of body dissatisfaction and cognitive biases toward sexuality.

Psoriasis is a chronic disease, involving skin and joints, characterized by inflamed lesions. Psoriasis negatively impacts the patients' quality of life due to the physical, emotional, and social burden that accompanies this condition. Also, psoriasis is associated with a number of psychiatric comorbidities, including sexual dysfunctions. The present study investigates the variables associated with sexual functioning in psoriasis patients. One-hundred-three psoriasis patients and 101 matched control subjects took part in the present study. Each participant completed five self-report measures investigating the presence of depression, anxiety and stress symptoms, body image, quality of life, and sexual experience. Our results show that differences in sexual activity, but not in sexual functioning, emerged between groups. In men with psoriasis, more sexual difficulties were associated with more negative automatic thoughts about sexuality. In women, more sexual difficulties were associated with more negative automatic thoughts; anxiety, depression, and stress; severity of symptoms; comorbid disease; age; quality of life. Our findings expand the current knowledge about sexual functioning in psoriasis and shed light on specific cognitive, psychological, and demographic variables associated with sexual impairment in men and women with psoriasis.

Psychosocial stress affects the change of mental distress under dermatological treatment-A prospective cohort study in patients with psoriasis.

Psoriasis is a chronic-inflammatory, immune-mediated disease leading to a state of increased systemic inflammation. Mental comorbidities often occur in the patients and may additionally affect the therapy outcome. Currently, it is unknown whether the disease severity, psychosocial stress or health-related quality of life determines the manifestation of anxiety/depression, or vice versa, in psoriasis. The interplay between these variables during the dermatological treatment of psoriasis remains to be elucidated in order to initiate appropriate psychological interventions and to identify patients at risk for comorbid anxiety/depression. In a prospective cohort study, the impact of disease severity, health-related quality of life and psychosocial stress on anxiety/depression were examined during the dermatological treatment in patients with moderate to severe psoriasis (patients with psoriasis = PSO). Patients were examined before (T1) and about 3 months after (T2) the beginning of a new treatment episode, in most cases by means of systemic therapy. Data were analysed, exploratory, using Bivariate Latent Change Score Models and mediator analyses. Assessments included patient-reported outcomes (Hospital Anxiety and Depression Scale/HADS, Perceived Stress Scale/PSS, Childhood Trauma Questionnaire/CTQ, Dermatology Life Quality Index-DLQI, Body Surface Area-BSA), at both T1 and T2. 83 PSO patients (37.3% women, median age 53.7, IQR 37.8-62.5, median BSA 18.0, IQR 9.0-40.0) with complete data of HADS and DLQI were included. In the total group, a higher anxiety/depression at T1 was associated with a lower improvement in psoriasis severity in the course of the dermatological treatment (γBSA  = 0.50, p < 0.001). In subgroups of PSO with low/high CTQ scores, anxiety/depression at T1 had no impact on the change in psoriasis severity. Only by tendency, in CTQ subgroups, a higher psoriasis severity at T1 was linked with a higher improvement in anxiety/depression at T2 (low/high CTQ, γHADS  = -0.16/-0.15, p = 0.08). An improvement in the health-related quality of life was positively associated with an improvement in anxiety/depression (Pearson's r = 0.49, p = 0.02). Here, the reduction of acute psychosocial stress seems to be a decisive factor, mediating this association (ß = 0.20, t [2,60] = 1.87; p = 0.07, 95% CI -0.01, 0.41). The results allude, that the initial severity of anxiety/depression may presumably have an impact on the treatment outcome in the total group. In contrast, analysing subgroups of patients with high/low childhood trauma, the impact of the initial disease severity on the course of anxiety/depression after a switch to a new dermatological treatment could not be conclusively ruled out. The latter results from the latent change score modelling should be treated cautiously because of the small sample size. A common aetiopathological mechanism for psoriasis and anxiety/depression might be assumed with impact of dermatological treatment on both. The change in perceived stress seems to play an important role in the manifestation of anxiety/depression, substantiating the need for adequate stress management in patients with increased psychosocial stress during their dermatological treatment.

Implementing well-being in the management of psoriasis: An expert recommendation.

Psoriasis causes detriment in a person's physical, mental and social health which impairs their quality of life (QoL). However, the current psoriasis management may not adequately address all relevant health domains. Since the goal of healthcare is to restore or maintain health, health outcomes should include all areas of the patient's overall health. Life satisfaction, QoL and patient well-being are essential to a comprehensive approach to the disease. With the inclusion of more people-centred policies, care of patients with psoriasis should evolve towards a holistic and integrated assessment of the disease impact, including subjective measures of well-being in order to encompass all aspects of health. The main objective of this expert review is to give the concept of well-being a place as an entity within the holistic therapeutic approach for patients with psoriasis. Identifying and defining common goals beyond the skin with the patient and testing them throughout the course of treatment will benefit and enhance treatment success. We propose a series of recommendations for application in clinical practice, providing tangible clinical guidance for implementing well-being in the management of psoriasis. Among the recommendations are the need to initially listen to the patient, to know their level of empowerment or what they want to achieve, their preferences in decision making, the evaluation of not only the physical but also the emotional impact of the disease (well-being), the definition of the aspects that can generate a cumulative deterioration of the disease throughout life, and a continuous assessment of the patient's preferences with the opinion of the expert clinician and the integration of the knowledge of external clinical evidence.
