Impact of psoriasis on health-related quality of life decreases over time: an 11-year prospective study

Real-world experience of secukinumab in moderate to severe psoriasis patients in Thailand: Characteristics, effectiveness, and safety

Secukinumab demonstrated high efficacy and favorable safety profile in patients with moderate-to-severe plaque psoriasis (PsO) in clinical trials. However, understanding of patient characteristics and clinical outcomes in real world in Thailand is still limited. To describe patient characteristics, effectiveness and safety of secukinumab in Thai PsO patients. This retrospective study analyzed data from medical records of adult PsO patients who initiated secukinumab at 7 dermatology centers from September 2017 to April 2021. Study outcomes included patient characteristics and changes in Psoriasis Area and Severity Index (PASI) score from baseline at weeks 4 and 16 after secukinumab initiation. Adverse events were recorded. Subgroup analyses by adherence rate and completeness of loading dose were performed. Of 163 patients, the mean (SD) age was 44.0 (14.0) years. Most patients (84.7%) were previously treated with topical therapy while 62.0% and 21.5% of patients had received systemic and biologic therapy, respectively. The mean baseline PASI score was 15.4 (9.3). Overall, the mean PASI score improved by 58.0% at week 4 and 78.4% at week 16. Statistically significant differences in PASI approvement were revealed among subgroups of patients with different loading dose and adherence rate. Adverse effects were reported in 8.0% of patients. The characteristics of patients in this study were slightly different from clinical trials in terms of demographic and clinical characteristics, as well as PsO treatment. Secukinumab was effective and safe in Thai patients with PsO, especially among those with complete loading dose and a higher adherence rate.

Mapping risk factors for cumulative life course impairment in patients with chronic skin diseases - a systematic review

Patients with chronic skin diseases suffer from physical and psychosocial impairments which can lead to a cumulative life-long burden. Therefore, the concept of cumulative life course impairment (CLCI) was introduced, referring to the non-reversible damage due to the persistent life-long burden. This systematic review (PROSPERO registry number: CRD42020179141) aimed at mapping the risk factors and the associated burden over time in patients with psoriasis, atopic dermatitis (AD) and hidradenitis suppurativa (HS). Three electronic databases were searched (date of the last search: December 2019). Studies with a longitudinal study design that assessed the association between a risk factor and the associated burden over time in patients with psoriasis, AD and HS were included. Quality assessment of the included studies was done using Critical Appraisal Skills Programme (CASP) checklists. In total, 40 publications reflecting 25 different studies were included: nine studies addressed patients with psoriasis, 13 patients with AD, two studies included patients with HS and one study enrolled patients with psoriasis and AD, respectively. Twenty-two potential risk factors with underlying evidence were found in this review. These risk factors include mainly sociodemographic (such as age or gender) and clinical (such as disease severity or comorbidities) variables. Disease severity and comorbidities were the most often studied risk factors, while only a few studies evaluated psychosocial risk factors over time. Patients with chronic skin diseases are at high risk to develop a life-long negative impact from the disease. However, there is a lack of data that evaluates the psychosocial burden and its influence on the patients' life course over time. The risk factors found in this review help to identify patients at risk, to treat them adequately and, ultimately, to prevent CLCI. These results can be the basis to develop a highly needed tool to assess the risk for CLCI in the future.

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

Background

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

Objective

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

Methods

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

Results

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

Conclusion

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

Effects of disease severity on quality of life in patients with psoriasis

Psoriasis is one of the leading dermatological diseases that can result in degradation in quality of life (QOL). We aimed to evaluate the effects of disease severity on QOL in psoriasis patients living in our region. Fifty-nine female and 41 male patients diagnosed with psoriasis were included in the study. The Psoriasis Area Severity Index (PASI) was used to determine disease severity. The Psoriasis Quality of Life Questionnaire (PQLQ) was used to evaluate QOL. The mean PASI score was 14.3 ± 10.1. The PQLQ and subscale scores were not affected by age, marital status, educational status, or age at onset of the disease etc. parameters (P > .05). Additional drug use, joint involvement, and lesion site exposure were found to increase psychosocial negativity scores significantly (P < .05). The mean scores for difficulties in daily life and treatment problems were significantly higher in men than in women (P < .05). There was a positive correlation between PASI scores and PQLQ, PQLQ subgroup scores. We found that QOL decreased with increasing severity of the disease. QOL as well as clinical severity should be considered in the planning and follow-up of psoriasis treatment. To evaluate the QOL, we believe that the PQLQ can be used as demonstrated in our study.

Pain associated with psoriasis: systematic scoping review protocol

INTRODUCTION

Psoriasis is a common chronic skin inflammatory disease. Its presentation, apart from affected skin areas, involves other unpleasant symptoms, such as pain. Pain deteriorates the patient's quality of life, impairing their daily behaviour and functioning. Therefore, the alleviation of pain in patients with psoriasis should be one of the most desired outcomes of successful treatment. The aim of this study is to summarise available evidence about pain in patients with psoriasis using systematic scoping review methodology in order to map the relevant literature.

METHODS AND ANALYSES

Our scoping systematic review will provide evidence synthesis of the literature, both quantitative and qualitative, about the pain associated with psoriasis, including pain associated with psoriatic arthritis. Any types of studies will be eligible for inclusion, and we will not have any time, language or publication status restrictions. We will search MEDLINE, Embase and PsycINFO via OVID, as well as Cochrane Central Register of Clinical Trials, Cochrane Database of Systematic Reviews via Cochrane Library, CINAHL via EBSCO, OpenGrey and ProQuest Dissertations and Theses Global. All databases will be searched from the date of their inception. Retrieved bibliographic records and potentially relevant full texts will be screened by two authors independently. Two researchers will extract data independently. Any discrepancies will be resolved via discussion or consultation of the third author, if necessary. To appraise studies, we will use a Mixed Methods Appraisal Tool, AMSTAR 2, Cochrane risk of bias tool and ROBINS. Our findings will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews.

ETHICS AND DISSEMINATION

The proposed study will not be conducted with human participants. We will only use published data and therefore ethics approval is not required. Our findings will be disseminated via peer-reviewed manuscript and conference reports.

The association between the clinical diversity of psoriasis and depressive symptoms: the HUNT Study, Norway

BACKGROUND

While a number of observational hospital-based studies have reported an association between psoriasis and depression, less is known about the clinical diversity of psoriasis and depressive symptoms.

OBJECTIVE

To investigate the associations of inverse psoriasis, psoriasis severity and psoriasis duration with depressive symptoms in a general population.

METHODS

We linked data from the population-based third Nord-Trøndelag Health Study (HUNT3) to the Norwegian Prescription Database (NorPD) and Statistics Norway. Depressive symptoms were assessed using the Hospital Anxiety and Depression Scale (HADS). Associations between psoriasis and depressive symptoms (HADS ≥ 8) were estimated using logistic regression.

RESULTS

Among 37 833 participants in HUNT3, we found a weak association between any psoriasis and the prevalence of depressive symptoms [fully adjusted odds ratio (OR) 1.12, 95% confidence interval (CI) 0.97-1.28]. The association with depressive symptoms was stronger when psoriasis was characterized by inverse anatomical distribution (OR 1.32, 95% CI 1.02-1.70), requirement of systemic psoriasis medication (OR 1.47, 95% CI 1.00-2.17) or long disease duration (OR 1.33, 95% CI 1.09-1.64). Conversely, when there was no inverse psoriasis distribution, no requirement of systemic medication, or shorter disease duration, psoriasis was not meaningfully associated with depressive symptoms.

CONCLUSION

Overall, depressive symptoms do not seem to be a major concern among subjects with psoriasis in a general Norwegian population. However, among subjects with inverse anatomical distribution, requirement of systemic psoriasis medication or long disease duration, depressive symptoms may be particularly important to address when evaluating the burden of psoriasis.

Quantifying harmful effects of psoriatic diseases on quality of life: Cardio-metabolic outcomes in psoriatic arthritis study (COMPASS)

OBJECTIVE

Up to 30% of patients with psoriasis suffer from concurrent psoriatic arthritis, and both the diseases have worse quality-of-life outcomes compared to the general population. There is limited literature comparing quality-of-life outcomes between these diseases. We seek to compare quality-of-life outcomes between both these groups.

METHODS

The current study is a cross-sectional analysis of a cohort of 252 patients with psoriatic diseases, who were recruited from 2 tertiary-care centers. A self-administered questionnaire was used to collect demographic and validated quality-of-life data using short form-12 (SF 12), health assessment questionnaire (HAQ), and dermatology life quality index (DLQI). Univariate and multivariate analyses were conducted to compare the quality-of-life outcomes.

RESULTS

We included 107 (42.5%) psoriatic arthritis and 145 (57.5%) psoriasis patients in the cohort. The groups had comparable gender distribution and co-morbid diseases prevalence, but arthritis patients were older and received biologics/DMARDs more frequently than psoriasis patients. The physical indices (identified by HAQ and SF 12 PCS) were worse for psoriatic arthritis, whereas the mental/psychometric indices (identified by DLQI and SF 12 MCS) were comparable between both the groups.

CONCLUSIONS

Despite aggressive therapy, physical quality of life was worse in psoriatic arthritis patients compared to psoriasis patients. The mental quality-of-life indices were comparable in both the groups and were still below the population norm. These results suggest need for screening for psoriatic arthritis in patients with psoriasis to reduce the burden of physical quality of life and screening for early signs of psychiatric illnesses in both these disease populations.

Psoriasis today: experiences of healthcare and impact on quality of life in a major UK cohort

AIM

To establish how people with psoriasis in the United Kingdom today experience living with their condition including diagnosis, treatment, healthcare provision and impact on daily life.

BACKGROUND

Psoriasis is a debilitating long-term inflammatory skin disease which can result in severe itching, discomfort and soreness, and may be associated with problems beyond the specific symptoms related to the skin. For many it is accompanied by difficult-to-manage treatment regimes, emotional distress and a negative impact on their quality of life and psychosocial functioning. To date there is little published information about the health experiences of people in the United Kingdom with psoriasis.

METHODS

A postal self-administered questionnaire was completed by members of the Psoriasis Association and the responses analysed (n = 1564).

FINDINGS

The findings suggest some similarities to surveys in other nations, but specifically highlighted that patients feel under-informed and are dissatisfied with current treatment regimes. Responses provided an insight into aspects of the condition that treatments should be targeting. Specific areas of negative impact on psychosocial functioning were identified, including the lack of available support for those experiencing emotional distress. The research provides important information about how the care of patients with psoriasis can be improved, especially at primary care level. This includes: improved training in psoriasis knowledge and awareness at general practitioner level and greater use of dermatology specialist nurses in primary care settings; more effective and manageable treatment regimes that target visible areas and general well-being; greater support for emotional distress and psychosocial functioning.

Psoriasis uncovered--measuring burden of disease impact in a survey of Australians with psoriasis

BACKGROUND/OBJECTIVES

Internationally, the understanding of psoriasis has advanced in recent years to the point now where it is no longer considered a benign or cosmetic skin condition but a systemic, immune-mediated disease associated with significant comorbidities and considerable detriment to quality of life. The aim of this study was to gain a better understanding of the physical, psychosocial and medical burden of psoriasis on Australian adults and the impact on health status.

METHODS

Two large-scale multi-centre cross-sectional studies of Australian adults with psoriasis were conducted during 2010 and 2011, with the participation of a national patient representative group (Psoriasis Australia). The studies were based on detailed questionnaires that were self-completed by individuals with psoriasis.

RESULTS

A total of 362 and 330 completed surveys were received in 2010 and 2011, respectively. A significant physical, psychosocial and medical burden was reported by the respondents. It was noteworthy that patients reported actively concealing their disease from the general public (83%), work colleagues (65%), friends (58%), employers (49%), family (40%), close friends (39%) and spouse/partner (20%). The mean five-dimension European quality of life (EQ-5D) score for the 2011 cohort was 0.73, representing a significant impact on their HRQoL. The presence of comorbidities, found in three-quarters of the cohort, was associated with an even greater detriment to their HRQoL (mean score 0.64).

CONCLUSIONS

Psoriasis imposes a significant psychosocial burden on the lives of patients, including a profound impact upon their personal and professional relationships, social interactions and quality of life, to a degree comparable to other serious chronic conditions. This study highlights the importance of collaboration between primary and specialist health-care providers in developing patient management strategies that address the spectrum of physical and psychological manifestations associated with psoriasis.

Self-management in daily life with psoriasis: an integrative review of patient needs for structured education

The aim of this integrative review is to identify and discuss patient needs for education to support self-management in daily life with psoriasis. As psoriasis increasingly gains recognition as a serious chronic autoimmune skin disease with long-term impairment on the life course, and not mainly a cosmetic problem, nurses are highly challenged to develop efficient education to support patient self-management. The paper includes five stages: (1) problem identification, (2) literature search, (3) data evaluation, (4) data analysis and synthesis, and (5) presentation, based on theoretic scaffolding around the concept “need.” Nineteen of 164 original papers within nursing, medicine and psychology, and reflecting patient perspective were included. To capture the patients' cultural understanding of the implications of the disease and care, we developed an interlevel model indicating that self-experienced burden of disease and its visibility, personal conditions such as illness perception, and the patient's age at onset time are high-impact factors that should be addressed in future structured patient education programmes. The research on patient needs has hitherto focused on adults, but the problems and vulnerability associated with having a chronic and visible disease during adolescence must be acknowledged, and patient education initiatives designed for this young group are recommended.

The burden of moderate to severe psoriasis: an overview

Psoriasis is a chronic, immune-mediated skin disorder that affects 1-3% of the general population worldwide. While considered a non-life-threatening disease, psoriasis represents a social and financial burden for patients and the healthcare system. Individuals suffer from disfigurement and from social stigmatization. Because the disease is usually persistent, patients with a diagnosis of psoriasis usually need lifelong care, which also means a lifetime of expenses. We aimed to conduct a comprehensive review of the evidence available concerning the social burden and costs of psoriasis. A search for the keywords 'quality of life' (QOL) or 'burden' or 'stigmatization' or 'psychological factors' in PubMed up to January 2010 yielded a total of 817 studies. QOL was affected by psoriasis to a degree comparable with diabetes or cancer. A search for 'cost-of-illness analyses', in the same period, yielded only seven papers satisfying entry criteria. All the studies but one were performed before biologics became available for psoriasis treatment. Direct costs were higher than indirect costs, with hospitalization representing the most significant item. Treatment costs showed wide variations between different studies. Reasons for these discrepancies are manifold including differences in the selection of the sample, as well as in the methods for calculating costs. There is a need to harmonize methodologies. For a final conclusive judgement of the cost effectiveness of innovative therapies such as biological agents, long-term economic consequences have to be evaluated and long-term remission rates and complications considered.

Physical and mental impact of psoriasis severity as measured by the compact Short Form-12 Health Survey (SF-12) quality of life tool

The Short Form-12 Health Survey (SF-12) is used to assess the patient's quality of life (QoL) using the physical component score (PCS) and the mental component score (MCS). The purpose of this study was to determine whether the SF-12 PCS and MCS are associated with psoriasis severity and to compare QoL between Murdough Family Center for Psoriasis (MFCP) patients and patients with other major chronic diseases included in the National Survey of Functional Health Status data. We used data from 429 adult patients enrolled in MFCP. Psoriasis Area Severity Index (PASI) was used to assess psoriasis severity at the time of completion of the SF-12 questionnaire. Other variables included age, sex, body mass index, psoriatic arthritis, psychiatric disorders, and comorbidities. Linear regression models were used to estimate effect sizes ± 95% confidence intervals. For every 10-point increase in PASI, there was a 1.1 ± 1.3 unit decrease in MCS (P=0.100) and a 2.4 ± 1.3 unit decrease in PCS (P<0.001). Psoriasis severity was associated with PCS and MCS after adjusting for variables, although the strength of the relationship was attenuated in some models. Psoriasis severity is associated with decreased QoL. SF-12 may be a useful tool for assessing QoL among psoriasis patients.

Large-scale, prospective, observational studies in patients with psoriasis and psoriatic arthritis: A systematic and critical review

Background

Observational studies, if conducted appropriately, play an important role in the decision-making process providing invaluable information on effectiveness, patient-reported outcomes and costs in a real-world environment. We conducted a systematic review of large-scale, prospective, cohort studies with the aim of (a) summarising design characteristics, the interventions or aspects of the disease studied and the outcomes measured and (b) investigating methodological quality.

Methods

We included prospective, cohort studies which included at least 100 adults with psoriasis or psoriatic arthritis. Studies were identified through searches in electronic databases (Pubmed, Medline, Cochrane library, Centre for Reviews and Dissemination). Information on study characteristics were extracted and tabulated and quality assessment, using a checklist of 18 questions, was conducted.

Results

Thirty five papers covering 16 cohorts met the inclusion criteria. There were ten treatment-related studies, only two of which provided a comparison between treatments, and six non-treatment studies which examined a number of characteristics of the disease including mortality, morbidity, cost of illness and health-related quality of life. All studies included a clinical outcome measure and 11 included patient-reported outcomes, however only two studies reported information on patient utilities and two on costs. The quality of the assessed studies varied widely. Studies did well on a number of quality assessment questions including having clear objectives, documenting selection criteria, providing a representative sample, defining interventions/characteristics under study, defining and using appropriate outcomes, describing results clearly and using appropriate statistical tests. The quality assessment criteria least adhered to involved questions regarding sample size calculations, describing potential selection bias, defining and adjusting for confounders and losses to follow-up, and defining and describing a comparison group.

Conclusion

The review highlights the need for well designed prospective observational studies on the effectiveness, patient-reported outcomes and economic impact of treatment regimes for patients with psoriasis and psoriatic arthritis in a real-world environment.

Impact of Psoriasis on Quality of Life: Relationship between Clinical Response to Therapy and Change in Health-related Quality of Life

BACKGROUND

Psoriasis exerts significant, negative, impact on patients' quality of life (QOL). Recently, the relationship between QOL and skin lesion improvement has been emphasized in the treatment of psoriasis patients.

OBJECTIVE

The purpose of study was to compare the QOL in psoriasis and other skin diseases, and to evaluate the generic QOL, skin specific QOL, stress, depression and anxiety before and after treatment in patients.

METHODS

A total of 138 patients with psoriasis were recruited in this study and 83 patients complete the questionnaire at week 16. Questionnaires were comprised of generic WHO QOL scale, dermatology specific questionnaires (Skindex-29), psoriasis life stress inventory (PLSI), Beck depression inventory (BDI), and Beck anxiety inventory (BAI). Clinical response was assessed by the PASI.

RESULTS

After treatment, health-related QOL was improved and PASI improvement showed smaller correlation with Skindex-29, compared with the correlations between self-reported severity score (SRSS) improvement and Skindex-29. Regression analysis revealed that duration, SRSS, stress, and depression were factors affecting baseline HRQOL in patients, and age, duration, and SRSS were predictors associated with HTQOL score changes.

CONCLUSION

Treatment improved HRQOL, BAI, BDI, and PLSI scores. Psoriasis may become more burdensome in groups of patients who suffer long disease duration, high SRSS, depression, and stressful environments.

Emerging drugs for psoriasis

BACKGROUND

Psoriasis is a relatively common, chronic and disabling skin disease, due to a disturbed proliferation and differentiation of keratinocytes, accompanied by vascular alterations and infiltration of inflammatory cells with a local T(H)1-type cytokine immune response. There is no cure, but several treatment options are available.

OBJECTIVE

The treatment of psoriasis is far from being satisfactory, due to the impractical modalities of topical treatment and the suboptimal safety profile of the systemic treatments available. In the last few years, parallel to an improved understanding of the disease pathogenesis, there has been a boosting of research in new agents for the treatment of psoriasis. These new agents are the focus of this paper.

METHODS

After a short review of the treatment options already available (mainly based on the available systematic reviews), we focused on agents that are still in clinical development (Phase I - III) and have not yet entered the market. For the purpose of this study, we systematically searched the main registries of ongoing trials up to August 2008.

RESULTS/CONCLUSION

The field is very dynamic, with both immunopharmacology of recombinant DNA techniques and more traditional small-molecule pharmacology actively delivering new agents. With the increasing number of new options, there is a need for research systems that enable to effectively collect long-term safety data on treated patients.

Medication adherence and health care costs associated with biologics in Medicaid-enrolled patients with psoriasis

BACKGROUND

Costs and patients' adherence related to biologics are important factors to consider while making informed decisions regarding therapy with biologics in psoriasis management.

OBJECTIVE

To examine predictors of adherence related to biologics, total health care costs, and service utilization among psoriasis patients.

METHODS

This was a longitudinal cohort study of psoriasis patients (<65 years old) enrolled in North Carolina Medicaid who were prescribed biologics (alefacept, efalizumab, and etanercept). Patients' medication adherence, health care costs, and service utilization patterns in the pre- and post-biologics period were examined.

RESULTS

Adherence to biologics was significantly higher compared with the other psoriasis medications (0.66 vs 0.39; p<0.001). Prescription costs were significantly higher in the post-biologics period (3796.77 US dollars vs 11,706.32 US dollars; p<0.001). However, total health care costs in the post-biologics period did not differ significantly from the pre-biologics period (14,662.22 US dollars vs 16,156.10 US dollars; p>0.05). Patients' adherence and health care costs did not differ significantly across the biologics. After controlling for other variables, patients had a significantly lower number of hospitalizations in the post-biologics period (p<0.001).

CONCLUSIONS

Although costs associated with prescriptions for biologics were higher, total health care costs did not differ significantly in the post-biologics period. Biologics had a better adherence rate compared with other psoriasis medications.

Assessing the Impact of Psoriasis and the Relevance of Qualitative Research

Living with psoriasis is a lifetime experience. The lack of a cure combines with a peculiar public response of disinterest if not prejudice and stigmatization. Various factors account for changes in quality of life measures that seem independent from disease severity and effectiveness of treatment. Merging a qualitative and individual case analysis with assessment of quality of life would represent a direction for future studies.

Testing and Reducing Skindex-29 Using Rasch Analysis: Skindex-17

The Skindex is a well-studied dermatology-specific health-related quality of life (HRQOL) instrument. The objective of this study was to test Skindex-29 using Rasch analysis and, if necessary, to refine it so that it would fit this item response theory based model. The Skindex-29 of 454 Italian dermatological patients was subjected to Rasch analysis to investigate threshold order, differential item functioning (DIF), and item and overall fit to the model. The Skindex-29 did not fit the Rasch model (P<0.001). The 5-point scoring system was re-grouped into three categories and demonstrated logical response order for all but one item. Rasch analyses of a combined emotion and social functioning subscale of Skindex-29 resulted in a 12-item psychosocial subscale. Five of seven items were retained in a symptoms subscale. Both subscales fitted the model (P=0.32 and 0.13, respectively) without significant individual item misfit or DIF (P>0.05). Classical psychometric properties such as response distribution, item-rest correlation, item complexity, and internal consistency of the two subscales of Skindex-17 were at least adequate. The Skindex-17 is a Rasch reduced version of Skindex-29, with two independent scores that can be used in the measurement of HRQOL in dermatological patients.
