Health-related quality of life in patients with psoriasis and atopic dermatitis measured with SF-36, DLQI and a subjective measure of disease activity

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.

Understanding Barriers Impacting upon Patient Wellbeing: A Nationwide Italian Survey and Expert Opinion of Dermatologists Treating Patients with Moderate-to-Severe Psoriasis

A nationwide cross-sectional online survey was administered to dermatologists managing patients with moderate-to-severe plaque psoriasis across Italy to obtain real-world dermatologists' perspectives on the impact of psoriasis and its treatment on patients' daily lives and quality of life (QoL). A total of 91 dermatologists (aged 39.1 ± 11.2 years) completed a 31-question survey and workshop sessions were undertaken in order to identify the best management approach to achieve patient wellbeing. Social (4.2 ± 0.1), physical (4.26 ± 0.2) and mental components (4.1 ± 0.3) were rated by dermatologists as contributing to patient wellbeing to similar extents. While a high proportion (85.4%; rating of 4.3 out of 5) of dermatologists felt that they considered the QoL of patients, a lower proportion (69.6%; rating of 3.7 out of 5) felt that patients were satisfied in this regard. The psoriasis area and severity index and body surface area were the instruments most frequently used to assess the physical domain, while interviews/questions and the dermatology life quality index were used to assess social and mental domains, with only 60% of dermatologists following up on these aspects. The importance of investigating the presence of comorbidities was recognized but not always carried out by many dermatologists, (>70%), particularly for obesity and anxiety/depression. This survey identified key components contributing to barriers impacting on the QoL of patients with moderate-to-severe psoriasis from the perspective of the dermatologist.

Acupuncture for Patients with Chronic Spontaneous Urticaria: A Randomized, Sham-Controlled Pilot Trial

OBJECTIVE

To determine the feasibility of conducting a full-scale randomized controlled trial (RCT) and investigate the basic information and safety of acupuncture for patients with chronic spontaneous urticaria (CSU).

METHODS

A total of 80 participants with CSU from July 2018 to July 2019 were randomly assigned to receive active acupuncture (n=41) on a fixed prescription of acupoints or sham acupuncture (n=39) with superficial acupuncture on non-acupuncture points through the completely randomized design. Patients in both groups received 5 sessions per week for 2 weeks, and participants were followed for a further 2 weeks. Feasibility was assessed by recruitment and randomization rates, retention of participants, treatment protocol adherence, and the incidence of adverse events (AEs). The clinical primary outcome was the changes from baseline weekly urticaria activity scores (UAS7) after treatment at 2 weeks. Secondary outcomes included the Visual Analogue Scale (VAS) score of itching intensity, Dermatology Life Quality Index (DLQI), Hamilton Depression Scale (HAMD), and Hamilton Anxiety Scale (HAMA).

RESULTS

A total of 80 participants were enrolled. The recruitment rate of 24.02%, randomization rate of 100%, a loss rate of 6.25%, and no obvious AEs were observed in either group. The decrease from baseline in the mean UAS7 total score at week 2 in the active acupuncture group was -8.63 (95%CI, -11.78 to -5.49) and -6.21 (95%CI, -9.43 to -2.98) in the sham acupuncture group for a between-group difference of -2.42 (95% CI, -6.93 to 2.07). The change in the DLQI, VAS of itching intensity, HAMA, and HAMD were a slightly better improvement trend in the active acupuncture group than the sham acupuncture group, but the between-group difference was not significant.

CONCLUSIONS

Active acupuncture had a better improvement trend in alleviating symptoms, improving quality of life and regulating the mood of anxiety and depression in patients with CSU than sham acupuncture. (Registration Nos. AMCTR-ICR-18000190 and ChiCTR2100054776).

Exploring the Relationship Between Dermatology Life Quality Index, Eczema Area and Severity Index, and Sleep Numerical Rating Scale and Pruritus Numerical Rating Scale in Patients with Atopic Dermatitis Treated with Dupilumab

Objective: Patients with atopic dermatitis (AD) experience decreased quality of life (QoL). Here we describe the relationship between severity and QoL-related scores in patients with moderate-to-severe AD treated with dupilumab. Patients and Methods: This was a real-life, retrospective, and observational study involving patients with AD treated with dupilumab. Treatment effectiveness was evaluated based on the changes in the eczema area and severity index (EASI), sleep quality numerical rating scale ,and pruritus numerical rating scale (PNRS), as well as the dermatology life quality index (DLQI). The relationship between each of them was analyzed. After the first data collection at baseline, patients were re-evaluated at 3 subsequent follow-ups (4, 8, and 12 months). Results: A total of 52 patients were enrolled in the study. At 4 months, the change in DLQI is more correlated with PNRSs (r = 0.643, P < 0.001) than the other scores considered. At 8 months, however, the change in DLQIs correlates similarly both with PNRSs (r = 0.644, P < 0.001) and with the change in EASIs (r = 0.633, P < 0.001). At 12 months of treatments, however, the trend reverses and the correlation with EASIs becomes higher (r = 0.735, P < 0.001) than PNRSs (r = 0.0.659, P < 0.001). Conclusions: The results of our study show that the reduction in the impact on QoL for AD patients in the first months of therapy with dupilumab correlates more with the control of pruritus than with the disappearance of skin lesions.

The Psoriatic Arthritis 5-Thermometer Scales (PsA-5Ts): Measurement Properties of a New Multidimensional Composite Tool for the Quick Assessment of the Overall Health Status in Psoriatic Arthritis

BACKGROUND

Psoriatic arthritis (PsA) is a heterogeneous condition that is difficult to assess. The goal of this research was to evaluate the clinimetric properties of the Psoriatic Arthritis 5-Thermometer Scales (PsA-5Ts), a new patient-reported outcome (PRO) to measure the overall health status in PsA patients.

METHODS

The PsA-5Ts were compared to composite measures of disease activity (DAPSA, PASDAS, CPDAI) and PROs (PsAID-12 and SF-36). The convergent validity was assessed through the Spearman's correlation coefficient and the discriminant validity through the receiver operating characteristic (ROC) curve analysis, applying the Minimal Disease Activity (MDA) as an external criterion.

RESULTS

The cross-sectional assessment included 155 patients. Significant high correlations were observed when comparing PsA-5Ts to composite indices of disease activity and PROs (all at significance levels of p < 0.0001). The PsA-5Ts subscales were highly significantly different in terms of MDA status (all at p < 0.0001). The PsA-5Ts had good discriminant validity like that of the DAPSA, CPDAI, PASDAS, and PsAID-12, and better than that of the SF-36, with an area under the ROC curve of 0.944 (65% CI 0.895-0.974).

CONCLUSIONS

The PsA-5Ts are an easy-to-use PRO that can be integrated with disease activity indices in the assessment of PsA in daily clinical practice.

Overview of alopecia areata for managed care and payer stakeholders in the United States

Alopecia areata (AA) is an autoimmune disease with a complex pathophysiology resulting in nonscarring hair loss in genetically susceptible individuals. We aim to provide health care decision makers an overview of the pathophysiology of AA, its causes and diagnosis, disease burden, costs, comorbidities, and information on current and emerging treatment options to help inform payer benefit design and prior authorization decisions. Literature searches for AA were conducted using PubMed between 2016 and 2022 inclusive, using search terms covering the causes and diagnosis of AA, pathophysiology, comorbidities, disease management, costs, and impact on quality of life (QoL). AA is a polygenic autoimmune disease that significantly impacts QoL. Patients with AA face economic burden and an increased prevalence of psychiatric disease, as well as numerous systemic comorbidities. AA is predominantly treated using corticosteroids, systemic immunosuppressants, and topical immunotherapy. Currently, there are limited data to reliably inform effective treatment decisions, particularly for patients with extensive disease. However, several novel therapies that specifically target the immunopathology of AA have emerged, including Janus kinase (JAK) 1/2 inhibitors such as baricitinib and deuruxolitinib, and the JAK3/tyrosine kinase expressed in hepatocellular carcinoma (TEC) family kinase inhibitor ritlecitinib. To support disease management, a disease severity classification tool, the Alopecia Areata Severity Scale, was recently developed that evaluates patients with AA holistically (extent of hair loss and other factors). AA is an autoimmune disease often associated with comorbidities and poor QoL, which poses a significant economic burden for payers and patients. Better treatments are needed for patients, and JAK inhibitors, among other approaches, may address this tremendous unmet medical need.

The Impact of Psoriasis and Atopic Dermatitis on Quality of Life: A Literature Research on Biomarkers

Psoriasis (PSO) and Atopic dermatitis (AD) are common inflammatory skin diseases that affect people of all ages globally. They negatively impact the quality of life (QoL) of patients in health-related aspects such as physical, psychological and mental functioning. Here, we conducted a review of studies relating to candidate biomarkers and indicators associated with QoL impairment in PSO and AD. Data research was performed using PUBMED and SCOPUS databases from inception to September 2022. Most of the included studies reported genomic or proteomic biomarkers associated with disease activity and QoL outcomes. Sociodemographic, clinical and therapeutic factors have also been implicated in deterioration of life quality in these patients. The inclusion of clinical characteristics, QoL impairment and co-diagnosis should be considered in drug development programs, since processing biomarkers based on an increased number of features in addition to drug class and disease will intensify the value of the biomarker itself, thereby maximizing the future clinical utility as a stratification tool.

Efficacy and Safety of Dimethyl Fumarate in Patients with Moderate-to-Severe Plaque Psoriasis: DIMESKIN-2, a Multicentre Single-Arm Phase IIIb Study

This open-label multicentre trial evaluated the efficacy and safety of oral dimethyl fumarate (DMF) in patients with moderate-to-severe plaque psoriasis in real-life clinical practice over 52 weeks. Disease severity and improvement were assessed using the psoriasis area severity index (PASI), body surface area (BSA) affected, and Physician Global Assessment (PGA). Quality of life (QoL) was assessed using the Dermatology Life Quality Index (DLQI) questionnaire. The visual analogue scale (VAS) was used to quantify pruritus and measure treatment satisfaction. A total of 141 patients were included, being 66.7% male, aged 49.1 ± 14.7 years and with disease duration of 16 ± 12.1 years. After 52 weeks, mean PASI decreased from 15.9 ± 6.8 to 1.5 ± 2 and 87.7%, 56.9% and 24.6% of patients achieved PASI 75/90/100 response, respectively. BSA decreased from 26.5 ± 14.8% to 2.7 ± 3.5% at 52 weeks, and 81.5% of patients had a PGA 0-1. DLQI scores decreased from 9.4 ± 6.4 to 2.1 ± 3.3, and VAS of pruritus decreased from 53 ± 28.4 to 19.1 ± 26.2 at Week 52. VAS for treatment satisfaction was 79.4 ± 29.4 at Week 52. A total of 34.2% of patients had an AE leading to permanent discontinuation. These findings show that DMF can significantly improve indices of disease severity, pruritus and QoL, with high levels of patient satisfaction and similar safety profile to other fumarates.

Clinicophotobiological Characterization of Photoaggravated Atopic Dermatitis

Importance

Photoaggravated atopic dermatitis (PAD) is estimated to affect 1.4% to 16% of patients with AD but remains poorly characterized with limited published data.

Objective

To provide detailed clinical and photobiological characterization of PAD.

Design, Setting, and Participants

This case series study used cross-sectional data collected from 120 consecutive patients diagnosed with PAD from January 2015 to October 2019 at a tertiary center referral unit for photobiology.

Main Outcomes and Measures

Routinely collected standardized clinical and photobiological data were analyzed using descriptive statistics, and regression analysis explored associations between demographic and clinical data.

Results

Of 869 patients who underwent photoinvestigation, 120 (14%) were diagnosed with PAD (69 female [58%]; median age, 45 [IQR, 31-61] years; range, 5-83 years; skin phototypes [SPTs] I-VI). Of these patients, 104 (87%) were adults. All patients had a history of AD, and most (62 of 104 [60%]) presented with sunlight-provoked or photodistributed eczema; median age at photosensitivity onset was 37 years (range, 1-72 years). Past-year Dermatology Life Quality Index score was greater than 10 for 80 of 103 adults (78%), and 82 of 119 (69%) had vitamin D (25-hydroxyvitamin D) level insufficiency or deficiency (<20 ng/mL; to convert ng/mL to nmol/L, multiply by 2.496). Broadband UV radiation provocation test results were positive for 112 patients (93%). In 28 patients (23%) with abnormal monochromator phototest findings, sensitivity occurred to UV-A, UV-B, and/or visible light, and UV-A of 350 ± 10 nm was the most prevalent wavelength. Photopatch test reactions were positive for 18 patients (15%). Patients with SPTs V to VI (31 [26%]) vs SPTs I to IV (89 [74%]) were younger at photosensitivity onset (median age, 24 years [IQR, 15-37 years] vs 40 years [IQR, 25-55 years]; P = .003), were more likely to be female (23 [74%] vs 46 [52%]; P = .03), and had a lower vitamin D status and a higher frequency of abnormal monochromator phototest findings.

Conclusions and Relevance

In this case series study, PAD affected patients with different ages and SPTs and was associated with substantially impaired quality of life. The findings suggest that confirming PAD through phototesting may provide better personalized care for patients through identification of provoking wavelengths, relevant photocontact allergies, and appropriate photoprotection advice.

Sharing Patient and Clinician Experiences of Moderate-to-Severe Psoriasis: A Nationwide Italian Survey and Expert Opinion to Explore Barriers Impacting upon Patient Wellbeing

A nationwide survey was conducted in adult patients with psoriasis (PsO) across Italy to obtain their real-world perspective of the impact of PsO on their wellbeing. Patients completed a 26-question survey (based on the patient benefit index; PBI, The Dermatology Life Quality Index; DLQI and the World Health Organization-five; WHO-5 wellbeing index) and workshop discussion sessions were undertaken by dermatologists to interpret results from the survey. 392 patients with PsO completed the survey. Analysis of results was restricted to patients who had moderate-to-severe plaque psoriasis (assessed by patients; n = 252; 64.3%). Dermatologists (n = 32) completed one question from the survey related to wellbeing and rated social, physical and mental domains as contributing to a similar extent, with comparable scores also observed by patients. For treatment, biologics yielded higher scores on average, whereas little difference was observed between topical and conventional systemic treatments. Only 23.8% of patients felt that their dermatologist was taking into consideration their wellbeing and 32.6% of the patients considered their therapy as inadequate in improving signs and symptoms of the disease. This survey identified key factors contributing to barriers impacting on patient wellbeing. Simple, but comprehensive questionnaires can provide important insight to patients’ needs that may significantly increase clinician awareness during visits leading to tailored treatment.

Incidence of Psoriatic Arthritis Among Patients Receiving Biologic Treatments for Psoriasis: A Nested Case-Control Study

OBJECTIVE

To investigate the effect of biologic treatments for psoriasis on the incidence of psoriatic arthritis (PsA).

METHODS

This retrospective cohort study was conducted using electronic medical records from a large health maintenance organization. Patients who received biologic treatment for psoriasis and were not diagnosed as having PsA before or at the time of biologic treatment initiation were included. Control psoriasis patients who did not receive biologic treatment were matched by age at time of diagnosis, sex, time from psoriasis diagnosis until treatment initiation, maximum body mass index, and smoking status. The groups were different in most characteristics. Therefore, propensity score matching was implemented. Log rank test and multivariable Cox proportional hazards regression were used to compare the groups.

RESULTS

Overall, 1,326 patients were included, of whom 663 had received biologic treatment and 663 had not. The Kaplan-Meier curve for the propensity score-matched groups reflected a statistically significant increased risk for PsA among the control group compared to the biologic treatment group. The results of the multivariable Cox regression showed that the control group had a significantly higher risk for PsA compared to the biologic treatment group within 10 years of follow-up (adjusted hazard ratio 1.39 [95% confidence interval 1.03-1.87]).

CONCLUSION

Our findings show a statistically and clinically significant decreased risk for developing PsA among patients with psoriasis who receive biologic treatments. The results suggest that biologic medications should be considered for patients who present with significant risk factors for PsA at an earlier stage of treatment.

The IL-4, IL-13 and IL-31 pathways in atopic dermatitis

Introduction: Atopic dermatitis (AD) is the most common inflammatory skin disease. It has a complex pathophysiology, with a combination of immune dysregulation and intrinsic barrier defects driving cutaneous inflammation and allergic symptomatology. The IL-4, IL-13 and IL-31 inflammatory pathways have been identified as hallmark features in the pathogenesis of the disease, contributing uniquely and synergistically to immune and barrier abnormalities as well as the key symptoms, such as pruritis. Novel therapeutics that target these pathways have been under development to find treatments for AD.Areas covered: This review discusses the IL-4, IL-13 and IL-31 pathways in AD. We will also detail novel targeted therapeutics that have recently been or are currently in clinical trials for AD. A literature search was conducted by querying Scopus, Google Scholar, PubMed, and Clinicaltrials.gov up to January 2021 using combinations of the search terms 'IL-4' 'IL-13' 'IL-31' 'atopic dermatitis' 'immune pathway' 'biologics' 'novel therapeutics' 'JAK/STAT inhibitors.'Expert opinion: The complex pathophysiology of AD advocates for innovation. Novel minimally invasive sampling modalities such as tape stripping will allow for a broader characterization of the immunomechanisms behind AD pathophysiology. This will allow for the continued development of a personalized medicine approach to treat AD.

A Qualitative Analysis of Provider Notes of Atopic Dermatitis-Related Visits Using Natural Language Processing Methods

Introduction

Real-world disease management of atopic dermatitis (AD) is hampered by a lack of consistency between providers that treat AD regarding assessment of severity, disease activity, and quality of life. Variability and inconsistency in documentation makes it difficult to understand the impact of AD. This study summarizes AD-related symptoms and concerns captured in unstructured qualitative provider notes by healthcare providers during visits with patients with AD.

Methods

Provider notes were obtained for patients with AD (n = 133,025) from a USA-based ambulatory electronic health records system. The sample included both children (n = 69,551) and adults at least 18 years of age (n = 63,474) receiving treatment from a variety of specialties including primary care, dermatology, and allergy/immunology. Key skin-related words were identified from a review of a sample of notes and natural language processing (NLP) was applied to determine the frequency of the keywords and bigram patterns.

Results

Provider notes largely focused on symptoms (primarily itch) and symptom relief rather than the impact of AD on work or lifestyle. Despite the known relationship between itch and skin pain, neuralgia was not widely documented. Compared to primary care providers, dermatologists’ and allergist/immunologists’ notes had more documentation of symptom-related issues. Personal and work/life burden issues were not widely documented regardless of specialty.

Conclusion

The topics documented in case notes by healthcare providers about their patients with AD focus largely on symptoms and, to a lesser extent, treatment, but do not reflect the burden of AD on patients’ lives. This finding highlights a potential care gap that warrants further investigation.

Decision-Analytic Modeling for Time-Effectiveness of the Sequence of Induction Treatments for Moderate to Severe Plaque Psoriasis

Importance

Systemic psoriasis treatments vary in efficacy and cost but also in time until onset of action. Patients with no response to a first induction treatment are typically switched to another, and some patients require several treatments before they see an improvement.

Objective

To determine the most cost-effective sequence of induction treatment through a comparative time-effectiveness analysis of different systemic treatment sequences currently licensed in Germany for moderate to severe plaque psoriasis.

Design, Setting, and Participants

This time-effectiveness analysis used a decision-analytic model set in the German health care system. The population simulated to receive the treatment sequences consisted of adult men and women with psoriasis vulgaris or plaque type psoriasis eligible for systemic treatment. Systematic reviews were performed to generate model input values. Data were collected from November 1 through December 15, 2017, and analyzed from January through August 2018.

Interventions

Five treatment sequences frequently used in Germany, identified through an online expert survey (response rate, 10 of 15 [66.7%]), and 4 theoretical sequences starting with a biological agent. Treatments included methotrexate sodium (MTX), cyclosporine (CSA), fumaric acid esters (FAE), adalimumab (ADA), ixekizumab (IXE), infliximab (INF), and secukinumab (SEC).

Main Outcomes and Measures

Two health states were defined: responder (patients achieving a Psoriasis Area Severity Index [PASI] ≥75) and nonresponder (PASI <75). Probability values were defined as response rates of PASI-75. Treatment effects were determined by the mean change in Dermatology Life Quality Index (DLQI) score. Time until onset of action was assessed as weeks until 25% of patients reach PASI-75. Individual time-effectiveness ratios were calculated per treatment sequence as time until onset of action (in weeks) per minimally important difference (MID) in DLQI and were subsequently ranked.

Results

Treatment sequences starting with a biological agent, including IXE-INF-SEC (1.4 weeks per DLQI-MID), INF-IXE-SEC (2.05 weeks per DLQI-MID), SEC-IXE-ADA (2.1 weeks per DLQI-MID), and ADA-IXE-SEC (2.8 weeks per DLQI-MID) were more time-effective than frequently used treatment sequences, including MTX-SEC-ADA (6.8 weeks per DLQI-MID), MTX-ADA-IXE (7.0 weeks per DLQI-MID), MTX-ADA-SEC (7.2 weeks per DLQI-MID), MTX-FAE-ADA (10.05 weeks per DLQI-MID), and FAE-MTX-CSA (11.5 weeks per DLQI-MID). The results were robust to deterministic sensitivity analyses.

Conclusions and Relevance

When allocating monetary resources, policy makers and regulators may want to consider time until patients experience an MID in their quality of life as an additional outcome measure.

Impact of Atopic Dermatitis and Chronic Hand Eczema on Quality of Life Compared With Other Chronic Diseases

: The aim of this study was to conduct 3 literature reviews to examine the impact of atopic dermatitis (AD) and chronic hand eczema (CHE) on health-related quality of life (HRQoL) compared with other chronic conditions by comparing reported utility scores of 4 commonly used generic HRQoL instruments. A systematic search was performed using PubMed, ScienceDirect, MEDLINE, EMBASE, Health Technology Assessment database, and ScHARRHUD. Inclusion criteria included, but were not limited to, patients of any age, studies from any location, publications reporting utility data based on EuroQoL 5 dimensions, the EuroQoL 5-dimension Visual Analog Scale, the Short-Form Health Survey, and the Short-Form 6 Dimensions in the English language. Inclusion criteria were met by 16 articles for AD, 25 articles for chronic conditions, and 9 articles for CHE. The findings of this review highlight that the disutility and loss in HRQoL of patients with AD and CHE are similar to or higher than other chronic conditions, such as cancer or hepatitis.

When life is an itch: What harms, helps, and heals from the patients' perspective? Differences and similarities among skin diseases

Itch is the commonest skin-related symptom, associated with a high psychosocial and economic burden. While the main focus of itch research lies on a few chronic skin diseases, only little is known about the perception of itch, itch-aggravating/-relieving factors and treatment preferences in patients with acute and chronic itch of various etiology. In this cross-sectional study, we assessed these aspects in 126 patients (mean age 61.7 ± 18.4 years, 67 females, median itch duration 3.9 years) using a 78-item questionnaire. The diseases were categorized into 11 diagnostic groups for descriptive analysis; the three most frequent groups ("atopic dermatitis," "nonatopic eczema," "inflammatory dermatoses") were statistically compared. Itch was most often perceived as localized 42.9%, burning (40.5%), and worrying (39.7%) with worsening in the evening (49.2%), due to warmth (42.1%) and sweating (26.2%). While itch perception, itch-aggravating factors and treatment preferences differed broadly among patients, the itch-relieving personal strategies were more uniform ("scratching by hand 70.6%, applying topicals 57.9%). Also, 69.8% of patients suffered from itch-related sleep disturbance, consequently affecting their relatives in 30.0%. Subgroup comparisons revealed significant differences regarding itch-aggravating factors (P = .0012) and itch duration (P = .0082). Patients rated the antipruritic effectiveness of phototherapy, "complementary and alternative medicine" and "other tablets" as high, but oral antihistamines, "cortisone tablets" and any topical as only moderately efficacious. The preferred administration of an ideal itch treatment was "creams/ointments" (51.6%) or "tablets" (35.7%), only few patients preferred "injections" or "patches." Consideration of such differences and similarities in itch characteristics and treatment preferences could help to better tailor treatment in itch patients.

Acceptance of Illness, Satisfaction with Life, Sense of Stigmatization, and Quality of Life among People with Psoriasis: A Cross-Sectional Study

INTRODUCTION

Psoriasis is a complex disease with a heterogeneous presentation, which may have a profound effect on the everyday functioning of patients. As a strongly stressogenic disease, psoriasis may cause lack of illness acceptance and contribute to negative changes in self-image. Usually, psoriasis also has a detrimental effect on quality of life. The aim of this study is to determine the levels of illness acceptance, satisfaction with life, stigmatization, and quality of life in people with psoriasis, to analyze relationships among these variables, and to verify whether they are modulated by selected sociodemographic factors.

METHODS

A total of 366 people with psoriasis treated at the Dermatology and Medical Cosmetology Clinic in Białystok were included. The study was conducted using a short survey prepared by the authors and five validated psychometric scales: Acceptance of Illness Scale (AIS), Satisfaction with Life Scale (SWLS), 6-item Stigmatization Scale, 33-item Feelings of Stigmatization Questionnaire, and Dermatology Life Quality Index (DLQI).

RESULTS

Median AIS score was 24 pts, which corresponds to a moderate level of illness acceptance. The level of illness acceptance among men was significantly higher than among women. More than half of respondents assessed their satisfaction with life as low. Men showed low levels of satisfaction with life slightly more often than women. Patients living in the countryside showed high levels of satisfaction with life significantly more often than those living in cities/towns. Mean scores for the 6-item Stigmatization Scale and the 33-item Feelings of Stigmatization Questionnaire were 8.73 pts and 90.06 pts, respectively, with no significant differences between the results of male and female patients. The DLQI scores for the study group ranged between 0 and 30 pts, with the mean value of 17.81 pts corresponding to a severe deterioration of quality of life. Statistically significant differences between quality of life and all sociodemographic variables were demonstrated.

CONCLUSIONS

People with psoriasis participating in this study showed moderate levels of illness acceptance and stigmatization, low level of satisfaction with life, and moderately deteriorated quality of life. Acceptance of illness was significantly modulated by patient sex. The level of illness acceptance among men was significantly higher than among women. Furthermore, illness acceptance exerted a significant effect on satisfaction with life in psoriasis patients. Place of residence exerted significant effects on satisfaction with life (higher in countryside dwellers), sense of stigmatization (stronger in countryside dwellers), and quality of life (more severely deteriorated in city/town dwellers). Disease duration significantly affected the degree of life satisfaction, sense of stigmatization (measured using a 33-item Feelings of Stigmatization Questionnaire), and quality of life among patients with psoriasis.

A changed life: the life experiences of patients with psoriasis receiving biological treatment

BACKGROUND

Psoriasis has a large negative impact on quality of life and is associated with both depression and anxiety. The introduction of biologics has improved treatment outcomes, but the ways in which patients perceive these improvements are not well characterized.

OBJECTIVES

To investigate the everyday life experiences of patients with psoriasis receiving biological treatment in order to gain an understanding of their needs and to improve the quality of care.

METHODS

A qualitative narrative methodology was utilized. In total 48 h of participant observations during consultations, and 15 semistructured interviews, were conducted with patients receiving biological treatment. Data were analysed according to Ricoeur's theory of interpretation.

RESULTS

Receiving biological treatment was experienced as a turning point, with a significant impact on physical, psychological and emotional levels. However, psychological consequences, such as isolation and social withdrawal, seemed to be a part of the patient's identity; the negative perceptions of psoriasis left marks behind that affected the patient's self-image. Perceived fear of discontinuation of the biological treatment resulted in insecurity, and patients were reluctant to initiate discussion about these concerns with healthcare professionals.

CONCLUSIONS

Providing assistance when patients enter the transition of receiving biological treatment may be important. Patients' fear of biological treatment being discontinued is an ongoing issue that healthcare professionals could address.

Impact of atopic dermatitis on quality of life in adults: a systematic review and meta-analysis

Atopic dermatitis (AD) can affect quality of life (QoL) of adult patients in whom the condition can be severe and persistent. There are currently no systematic reviews of the impact of AD on adults. This paper provides the first systematic literature review and meta-analysis of the impact of AD on QoL in adults. A systematic search was conducted using MEDLINE, Scopus, and Web of Science for articles published until October 2018. Inclusion criteria were a clinical diagnosis of AD, adult patients, and QoL as an outcome measure. Interventions were excluded. A total of 32 studies were included. While QoL was assessed using Dermatology Life Quality Index (DLQI) in 25 studies, there was heterogeneity in the tools used to measure disease severity across studies. Meta-analysis of the seven studies that used the SCORAD to measure disease severity showed severity to be significantly related to poorer QoL. The remaining 18 studies also showed increased disease severity significantly related to poorer QoL. When compared to healthy controls, AD patients demonstrated significantly lower QoL, but findings were mixed in studies that compared QoL in AD to other skin conditions. The findings highlight the significant impact that AD has on QoL in adults and the need for validated and relevant QoL measures to be implemented in clinical assessments for AD. Areas that require further research include an exploration of gender differences in QoL and the use of longitudinal study designs to explore factors that may cause differences in QoL ratings.

Characterizing treatment-related patient needs in atopic eczema: insights for personalized goal orientation

BACKGROUND

Atopic eczema (AE) is a common and burdensome chronic skin disease. Clinical guidelines suggest an evidence-based, personalized and stepwise treatment approach. Only few studies have so far focused on the specific patient needs in treatment.

OBJECTIVES

To characterize therapeutic needs of patients with AE in routine care.

METHODS

Nationwide cross-sectional study in 91 dermatology practices and outpatient clinics. Descriptive statistics were used for valuation. Comparisons of HRQoL and general health status were performed including subgroups (age, gender and disease duration). Group comparisons of patient needs were performed for age groups, gender and disease duration. Correlations between patients' needs (PNQ) and HRQoL, generic health status and severity were tested. In addition, a hierarchical regression analysis was performed to determine which variables contribute to explain the variance in patient needs.

RESULTS

Analysis of 1678 patients (60.5% female, mean age 38.35 ± 15.92 years) revealed a high disease burden with mean SCORAD of 42.26 ± 18.63, mean DLQI of 8.49 ± 6.45 and mean EQ VAS of 63.62 ± 21.98. Among the patient needs that were most frequently rated as 'quite important'/'very important' were as follows: 'to be free of itching' (96.0%), 'to get better skin quickly' (87.7%) and 'to be healed of all skin defects' (85.7%). In general, older people, women and patients who had been diagnosed with AE for 1 year or less rated the treatment needs as more important than younger patients, men and patients who had been diagnosed with AE for more than 1 year. Major determinants of higher needs were skin-related quality of life impairments, higher disease severity and higher age.

CONCLUSIONS

Patients with AE show a high number and variety of therapeutic needs related to disease signs and symptoms, which are associated with individual disease burden. The patient needs vary substantially according to patient characteristics. Identification of patient-specific needs may support personalized, patient-centred care and shared decision-making.

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

BACKGROUND

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

OBJECTIVES

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Diagnostic and therapeutic guidelines for plaque psoriasis - Brazilian Society of Dermatology

Psoriasis is a chronic inflammatory disease that affects 1.3% of the Brazilian population. The most common clinical manifestations are erythematous, scaling lesions that affect both genders and can occur on any anatomical site, preferentially involving the knees, elbows, scalp and genitals. Besides the impact on the quality of life, the systemic nature of the disease makes psoriasis an independent risk factor for cardiovascular disease, especially in young patients with severe disease. By an initiative of the Brazilian Society of Dermatology, dermatologists with renowned clinical experience in the management of psoriasis were invited to form a work group that, in a partnership with the Brazilian Medical Association, dedicated themselves to create the Plaque Psoriasis Diagnostic and Treatment Guidelines. The relevant issues for the diagnosis (evaluation of severity and comorbidities) and treatment of plaque psoriasis were defined. The issues generated a search strategy in the Medline-PubMed database up to July 2018. Subsequently, the answers to the questions of the recommendations were devised, and each reference selected presented the respective level of recommendation and strength of scientific evidence. The final recommendations for making up the final text were worded by the coordinators.

Efficacy and safety of acupuncture for patients with chronic urticaria: study protocol of a randomized, sham-controlled pilot trial

Background

Chronic urticaria (CU) is a refractory skin disease with long duration and a high recurrence rate. Acupuncture has been widely used for the treatment of CU in clinical practice in China. However, until now, there has been no appropriately designed randomized controlled trial (RCT) to provide explicit evidence about the effectiveness of acupuncture for the treatment of CU worldwide. Therefore, we plan to conduct a pilot study to explore its effectiveness and safety and determine the feasibility of studying acupuncture in a future, full-scale, RCT of CU.

Methods/design

This randomized, sham-controlled, participant-blinded and assessor-blinded pilot trial is underway in China. A total of 60 participants with CU will be randomly assigned to two groups in a 1:1 ratio: one treated with real acupuncture and the other with sham acupuncture, for 10 sessions over 2 weeks. The experimental group will receive acupuncture on a fixed prescription of acupoints, whereas the control group will receive sham acupuncture, namely minimal acupuncture on non-acupuncture points. The primary outcome will be the urticaria activity score (UAS). The secondary outcomes will include a visual analogue scale (VAS) score for itching intensity, the Dermatology Life Quality Index (DLQI), the Hamilton Depression Scale (HAMD), the Hamilton Anxiety Scale (HAMA), the humoral immunity index, serum total IgE, and adverse events. The UAS, VAS for itching and the DLQI will be conducted at baseline and at 1, 2, 3, and 4 weeks after randomization. The HAMD, HAMA, humoral immunity index, and serum total IgE will be assessed at baseline and at 2 weeks after randomization. Adverse events will be summarized at 1 week and 2 weeks after randomization.

Discussion

The pilot study mainly aims to investigate trial feasibility, and confirm basic information about its effects and safety. Results of this trial will help clarify whether the acupuncture treatment is beneficial for symptom improvement in patients with CU. The finding of this study will provide preliminary evidence on the effectiveness and safety of acupuncture for CU.

The impact of different rheumatic diseases on health-related quality of life: a comparison with a selected sample of healthy individuals using SF-36 questionnaire, EQ-5D and SF-6D utility values

Background: Given the high prevalence of rheumatic diseases, there is a need to determine which conditions have the greatest impact on health-related quality of life (HRQoL). The main aim of this study was to explore the HRQoL scores among 14 different rheumatic diseases and to compare them with the results of a selecting sample of healthy controls. Methods: 2633 patients of an ongoing cohort have been enrolled. Rheumatic diseases were classified into five diagnostic groups: inflammatory rheumatic diseases, connective tissue disorders, symptomatic peripheral osteoarthritis, soft tissue disorders, and osteoporosis. For comparison were used 649 healthy controls. The HRQoL was evaluated with the Medical Outcomes Study Short-Form 36 Health Survey (SF-36), the EuroQol five Dimensions (EQ-5D) questionnaire, and the Short-Form six Dimensions (SF-6D) questionnaire. Results: The five major rheumatic disease groups, compared to healthy people, significantly impaired all eight health concepts of the SF-36 (p <0.0001). Similar results were found for EQ-5D and SF-6D. The patients with inflammatory rheumatic diseases have poorer self-reported health status than those without arthritis in all domains of living, but particularly with respect to scales measuring aspects of physical functioning or mobility, role limitation due to physical health problems and usual activities, and bodily pain. Rheumatoid arthritis had the largest negative impact on HRQoL, followed by fibromyalgia, vertebral fractures due to osteoporosis, hip osteoarthritis, and systemic sclerosis. Conclusions: Our results indicate that rheumatic diseases have a clearly detrimental effect on the HRQoL, and physical domain is more impaired than mental and social ones. (www.actabiomedica.it)

Validation of an Egyptian Arabic Version of Skindex-16 and Quality of Life Measurement in Egyptian Patients with Skin Disease

PURPOSE

To translate and cross-culturally adapt the Skindex-16, a brief skin-disease-specific QoL questionnaire, into Arabic for Egyptians and to evaluate its measurement properties in Egyptian patients with skin disease.

METHOD

Translation and cultural adaption were performed following guidelines for cross-cultural adaption of health-related quality of life measures. Subsequently, Skindex-16 was administered to 500 consecutive dermatological patients and 500 healthy persons for verification of its reliability and validity. Next, we examined the effect of skin disorders on QoL as well as influences of age, sex, socioeconomic level, education, and use of medication on skin disease-related QoL.

RESULTS

The instrument showed high internal consistency reliability and good construct and content validity. The quality of life was most deteriorated in the emotional domain followed by symptoms domain (mean percentage score 55.5 ± 23.1 and 31.7 ± 26.8 respectively), while functioning was the least affected domain (mean percentage score 29.1 ± 26.8). Higher total Skindex-16 scores were observed for patients with psoriasis, urticaria, acne, and atopic dermatitis than those with vitiligo and alopecia areata. Educational level, social class, medication use, and family history influenced the impact of skin disease on overall QoL.

CONCLUSION

The adapted Egyptian Arabic version of Skindex-16 is valid and reliable; it showed that skin problems had a clinically significant impact on QoL in Egyptian patients.

Comparison of Different Remission and Low Disease Definitions in Psoriatic Arthritis and Evaluation of Their Prognostic Value

Objective.

There is no agreement on the optimal definitions for assessing disease state in patients with psoriatic arthritis (PsA), and some of the commonly used definitions do not include assessment of skin lesions. We investigated the performance of various definitions in patients with PsA and psoriasis.

Methods.

This was a posthoc analysis of data from the PRESTA study. The remission definitions analyzed were very low disease activity (VLDA) index, defined as 7/7 of the minimal disease activity (MDA) cutoffs; Disease Activity Index for PsA (DAPSA); and clinical (c-) DAPSA. The low disease activity (LDA) definitions analyzed were as follows: MDA defined as 5/7 cutoffs; MDA joint with both the tender joint count (TJC) and swollen joint count (SJC) cutoffs mandated; MDA skin where skin cutoff was mandated; MDA joint + skin where TJC, SJC, and skin cutoffs were mandated; DAPSA LDA; and cDAPSA LDA.

Results.

At Week 24, the proportions of patients achieving VLDA, DAPSA, and cDAPSA remission were 10%, 35%, and 37%, respectively. Of the patients achieving DAPSA and cDAPSA remission, 55% and 56%, respectively, had Psoriasis Area and Severity Index > 1. The proportions of patients achieving MDA 5/7, MDA skin, MDA joint, and MDA joint + skin were 44%, 19%, 36%, and 14%, respectively, versus 70% achieving DAPSA and cDAPSA LDA. Notable residual levels of psoriasis were observed in patients achieving the definitions that did not require skin disease control.

Conclusion.

VLDA and MDA definitions are more stringent than DAPSA and cDAPSA definitions for the assessment of PsA. The relevance of residual disease to patients, however, remains to be determined. [Clinical Trial registration:ClinicalTrials.govNCT00245960]

Quality of life and treatment goals in psoriasis from the patient perspective: results of an Austrian cross-sectional survey

BACKGROUND

Patients with psoriasis experience impairment in quality of life. Thus, high-quality dermatological care is of particular importance.

PATIENTS AND METHODS

We performed a nationwide cross-sectional survey in Austria (BQSAustria Psoriasis 2014/2015) with a special focus on quality of life and satisfaction with treatment among psoriasis patients predominantly treated at tertiary care centers.

RESULTS

Overall, 70.2 % of 1,184 patients reported impaired quality of life (DLQI 2-5: 29.4 %; 6-10: 19.3 %; 11-15: 11.5 %; 16-20: 5.2 % and > 20: 4.9 %) despite treatment over the preceding four weeks (topical treatment in 88.2 % of cases and/or systemic treatment in 38.7 %). On average, none of the 25 defined subjective treatment goals was achieved to a sufficient degree. In particular, 82.2 % of patients continued to have pruritus despite treatment, which was highly significantly associated with a poor general health status over the preceding week (Spearman's rank correlation; p  =  1.1e-45), the extent of body surface area (p  =  3.2e-11) and scalp area (p  =  3.2e-11) affected, as well as pain (p  =  2.3e-22). Treatment with a biologic was significantly correlated with higher patient satisfaction (Wilcoxon-Test, p  =  2.0e-16).

CONCLUSIONS

Despite dermatological care, the majority of Austrian psoriasis patients continues to experience impaired quality of life; there is potential for improvement in the achievement of treatment goals.

Prevalence of psoriatic arthritis in patients with psoriasis: A systematic review and meta-analysis of observational and clinical studies

BACKGROUND

Wide-ranging prevalence estimates of psoriatic arthritis (PsA) in patients with psoriasis have been reported.

OBJECTIVES

To assess the prevalence and incidence of PsA in patients with psoriasis.

METHODS

Two authors independently searched 3 databases for studies reporting on the prevalence or incidence of PsA in patients with psoriasis. A proportion meta-analysis was performed to calculate the pooled proportion estimates of PsA in patients with psoriasis.

RESULTS

A total of 266 studies examining 976,408 patients with psoriasis were included. Overall, the pooled proportion (95% confidence interval [CI]) of PsA among patients with psoriasis was 19.7% (95% CI, 18.5%-20.9%). In children and adolescents (<18 years of age), the pooled prevalence was 3.3% (95% CI, 2.1%-4.9%). The PsA prevalence was 22.7% (95% CI, 20.6%-25.0%) in European patients with psoriasis, 21.5% (95% CI, 15.4%-28.2%) in South American patients with psoriasis, 19.5% (95% CI, 17.1%-22.1%) in North American patients with psoriasis, 15.5% (95% CI, 0.009%-51.5%) in African patients with psoriasis, and 14.0% (95% CI, 95% CI, 11.7%-16.3%) in Asian patients with psoriasis. The prevalence of PsA was 23.8% (95% CI, 20.1%-27.6%) in studies in which the Classification Criteria for Psoriatic Arthritis were applied. The incidence of PsA among patients with psoriasis ranged from 0.27 to 2.7 per 100 person-years.

LIMITATIONS

Between-study heterogeneity may have affected the estimates.

CONCLUSIONS

We found that 1 in 4 patients with psoriasis have PsA. With the growing recognition of the Classification Criteria for Psoriatic Arthritis, more homogenous and comparable prevalence estimates are expected to be reported.

The association between psoriasis and health-related quality of life, work productivity, and healthcare resource use in Brazil

BACKGROUND

Psoriasis is a chronic, immune mediated inflammatory condition that affects a significant amount of the global population. Yet geographic variability in the consequences of psoriasis warrants region-level analyses.

OBJECTIVE

The current study contributes to the psoriasis outcomes literature by offering a comprehensive assessment of the humanistic and economic burden in Brazil.

METHODS

The 2012 Brazil National Health and Wellness Survey (N=12,000) was used to assess health-related quality of life (Short Form-12, version 2), work productivity, and healthcare resource use associated with experiencing psoriasis vs. no psoriasis, along with varying levels of psoriasis severity.

RESULTS

A total of 210 respondents reported diagnosis of psoriasis (N=157, 42, and 11 reporting mild, moderate, and severe psoriasis, respectively). Compared with controls, respondents with psoriasis reported diminished mental component summary scores and health utilities, as well as increased presenteeism, activity impairment, and physician visits over the past six months, adjusting for covariates. Among those with psoriasis, physical health decreased as psoriasis severity increased. Although work productivity and healthcare resource utilization did not differ with psoriasis severity, the high rates of productivity loss (e.g. 45.5% presenteeism in the severe psoriasis group) suggest an economic burden.

STUDY LIMITATIONS

Cost analyses were not performed, and cross-sectional patient-reported data limit causal conclusions and may reflect reporting biases.

CONCLUSIONS

Nevertheless, these results suggest a significant burden to patients with psoriasis across both humanistic and economic outcomes. The association between psoriasis and mental health aspects and health utilities were particularly strong and exceeded what would be considered clinically meaningful.

Dupilumab for the Treatment of Atopic Dermatitis

Atopic dermatitis (AD) is a common, chronic, inflammatory skin disorder with high physical and emotional burden. AD usually starts in early childhood and has a heterogeneous course. Emerging evidence suggests that IL-4 and IL-13 are key cytokines in the immunopathogenesis of AD. Dupilumab is a monoclonal antibody directed against IL-4 receptor α subunit, that blocks both IL-4 and IL-13 signaling. Data from Phase I-III studies revealed that dupilumab, administered as monotherapy or with topical corticosteroids, is effective and well tolerated in the treatment of adult patients with moderate-to-severe AD. A large proportion of patients receiving dupilumab had significant improvements in multiple efficacy indexes, including Eczema Area and Severity Index, Investigator's Global Assessment and SCORing Atopic Dermatitis scores. These results introduce a new era of targeted therapies in the management of AD.

Antipruritic Effect of Acupuncture in Patients with Atopic Dermatitis: Feasibility Study Protocol for a Randomised, Sham-Controlled Trial

This study aims to test the feasibility of a randomised clinical trial to evaluate how acupuncture affects atopic dermatitis (AD) symptoms and quality of life and to explore potential biomarkers that may be associated with AD. It is a sham-controlled trial in which 30 eligible patients will be randomly allocated in a 1 : 1 : 1 ratio to one of three groups: verum acupuncture (VA) group 1 (3 times weekly for 4 weeks); VA group 2 (twice weekly for 4 weeks); or sham acupuncture group (SA; twice weekly for 4 weeks). SA will consist of nonpenetrating acupuncture. Outcome measures will include the Visual Analogue Scale for itch, SCORing Atopic Dermatitis, and Eczema Area and Severity Index to evaluate AD symptoms improvement along with the Patient Oriented Eczema Measure and Dermatology Life Quality Index to assess quality of life. Measures will be collected at baseline, once weekly during the treatment period, and after a 4-week follow-up period. Blood collection will be at baseline and 4 and 8 weeks after treatment and compared with healthy controls. Illumina sequencing will be used to profile microRNA expression in each group to explore candidate microRNA biomarkers for specific effects of acupuncture in patients with AD. This trial is registered via US National Institutes of Health Clinical Trials registry (ClinicalTrials.gov) on 15 July 2016, identifier: NCT02844452.

Quality assessment of atopic dermatitis clinical practice guidelines in ≤ 18 years

Atopic dermatitis (AD) is a chronic inflammatory skin disease that affects the patients' quality of life greatly often from a very young age. Its worldwide incidence in children and adults varies, but it is usually among the first ten causes of dermatological consultation worldwide. There is a wide variety of treatment options for this condition including topical and systemic regimes. The decision to choose a treatment option in dermatological diseases is greatly influenced by the personal experience of each specialist, which increases variability in the selection of available therapies. Clinical practice guidelines (CPGs) not only offer recommendations supported on the available scientific evidence, but also are intended to assist in making appropriate decisions in clinical scenarios. To standardize the way in which CPGs should be developed, an instrument called AGREE II (Appraisal of Guidelines for Research and Evaluation) is used. In this study, ten clinical practice guidelines in ≤ 18 years were evaluated. Six domains (scope and purpose, stakeholder involvement, rigor of development, clarity and presentation, applicability, and editorial independence) were assessed for each guideline, by three reviewers. Most of the domains obtained high scores except in the applicability domain. It is suggested that future atopic dermatitis CPGs should emphasize in the facilitating factors and barriers that may influence the application of guideline recommendations.

Association between childhood allergic diseases, educational attainment and occupational status in later life: systematic review protocol

INTRODUCTION

Childhood allergic diseases may prevent affected children from achieving their academic potential. Potential mechanisms include absence from school due to illness and medical appointments. Experience of symptoms in classes or leisure time, and stigma associated with visible signs and symptoms, including skin disease, requirements for medication during school time or the need for specific diets, may also contribute to reduced educational attainment. Studies have investigated the association between specific allergic diseases and educational attainment. The aim of this study is to systematically review the literature on allergic diseases, educational attainment and occupational status, and if possible, calculate meta-analytic summary estimates for the associations.

METHODS

Systematic electronic searches in Medline, EMBASE, Cochrane, Cumulative Index to Nursing & Allied Health Literature (CINAHL), PsycINFO and education Resources Information Center (ERIC); hand search in reference lists of included papers and conference reports; search for unpublished studies in clinical trial registers and the New York Academy of Medicine Grey Literature Report; data extraction; and study quality assessment (Newcastle-Ottawa Scale) will be performed.

ANALYSIS

Data will be summarised descriptively, and meta-analysis including meta-regression to explore sources of heterogeneities will be performed if possible.

ETHICS AND DISSEMINATION

Dissemination in a peer-reviewed, open-access, international scientific journal is planned.

Quality of Life, Burden of Disease, Co-morbidities, and Systemic Effects in Vitiligo Patients

Vitiligo is a complex, systemic disease associated with many autoimmune and autoinflammatory conditions. Additionally, the cutaneous changes of vitiligo have significant effects on quality of life and self-esteem. Further efforts are needed to increase our understanding of vitiligo comorbidities as well as to increase awareness of the psychological effects of vitiligo.

Incremental burden of cardiovascular comorbidity and psoriatic arthritis among adults with moderate-to-severe psoriasis in five European countries

BACKGROUND

Moderate-to-severe psoriasis is associated with reduced health-related quality of life (HRQoL). Individuals with psoriasis are at increased risk for other medical conditions, but little information quantifies the incremental burden of psoriasis-associated comorbidity among European adults, and data have generally been limited to clinical samples.

OBJECTIVE

To quantify the incremental burden of cardiovascular comorbidity and psoriatic arthritis among adults with moderate-to-severe psoriasis in the general population of France, Germany, Italy, Spain and the United Kingdom (EU5).

METHODS

All measures were self-reported and came from the 2010-2013 EU5 National Health and Wellness Surveys (NHWS). Moderate-to-severe psoriasis was identified by >10% body surface area affected by psoriasis and/or use of therapies for moderate-severe disease. Outcomes were SF-12v2/SF-36v2 mental and physical component summary scores (MCS and PCS, respectively), SF-6D health utility, Work Productivity and Activity Impairment (WPAI) questionnaire and healthcare use in the past 6 months. Generalized linear models compared across cardiovascular comorbidity (CV) or psoriatic arthritis (PsA) groups vs. non-CV or non-PsA groups with appropriate link functions to adjust for covariates.

RESULTS

Among moderate-to-severe psoriasis respondents (n = 957), 19.8% (n = 190) reported CV comorbidity and 12.3% (n = 118) reported PsA. After adjustment for covariates, CV comorbidity was associated with 3.0 points lower MCS, 3.4 points lower PCS and 0.05 points lower SF-6D (all P < 0.01). Likewise, they had greater mean work impairment (48% vs. 33%), more activity impairment (48% vs. 37%), and more healthcare provider visits (8.8 vs. 6.9), emergency room visits (0.65 vs. 0.31) and hospitalizations (0.61 vs. 0.22) (all P < 0.05). Compared to non-PsA respondents, PsA respondents also had worse mean MCS (2.6 points), PCS (6.3 points) and SF-6D scores (0.07 points), and more work impairment (52% vs. 34%), activity impairment (54% vs. 38%) and healthcare provider visits (10.5 vs. 6.9) (all P < 0.05).

CONCLUSION

CV comorbidity and PsA were associated with significant incremental burden among EU5 adults with moderate-to-severe psoriasis.

Treating Psoriasis and Psoriatic Arthritis: Position Paper on Applying the Treat-to-target Concept to Canadian Daily Practice

Objective.

To develop preliminary treat-to-target (T2T) recommendations for psoriasis and psoriatic arthritis (PsA) for Canadian daily practice.

Methods.

A task force composed of expert Canadian dermatologists and rheumatologists performed a needs assessment among Canadian clinicians treating these diseases as well as an extensive literature search on the outcome measures used in clinical trials and practice.

Results.

Based on results from the needs assessment and literature search, the task force established 5 overarching principles and developed 8 preliminary T2T recommendations.

Conclusion.

The proposed recommendations should improve management of psoriasis and PsA in Canadian daily practice. However, these recommendations must be further validated in a real-world observational study to ensure that their use leads to better longterm outcomes.

Need for Improvement in Current Treatment of Psoriatic Arthritis: Study of an Outpatient Clinic Population

OBJECTIVE

To explore the burden of skin, joint, and entheses manifestations in a representative psoriatic arthritis (PsA) outpatient cohort in the biologic treatment era.

METHODS

This was a cross-sectional study of 141 PsA outpatients fulfilling the ClASsification for Psoriatic ARthritis (CASPAR) criteria and examined between January 2013 and May 2014. Selected disease activity measures were explored including Disease Activity index for PSoriatic Arthritis (DAPSA), Composite Psoriatic Disease Activity Index (CPDAI), Psoriatic Arthritis Disease Activity Score (PASDAS), Disease Activity Score for 28 joints (DAS28), Simplified Disease Activity Index (SDAI), and Psoriasis Area Severity Index (PASI). Dermatology Life Quality Index (DLQI), minimal disease activity (MDA), and remission criteria were assessed.

RESULTS

Median (range) DAPSA was 14.5 (0.1-76.4), CPDAI 5 (1-11), PASDAS 3.1 (2.1-4.2), DAS28-erythrocyte sedimentation rate (ESR) 3.2 (0.6-6.4), SDAI 8.6 (0.1-39.5), PASI 1.2 (0.0-19.7), and DLQI 2.0 (0-17). The MDA criteria were fulfilled by 22.9% of the patients. DAPSA ≤ 4, CPDAI ≤ 2, PASDAS < 2.4, DAS28-ESR < 2.4, SDAI < 3.3, and Boolean's remission criteria were fulfilled by 12.1, 9.3, 7.8, 26.2, 21.3, and 5.7% of patients, respectively. The number of satisfied patients was similar regardless of whether the group was treated with tumor necrosis factor inhibitors.

CONCLUSION

Our real-life data indicate that there is still a need for improvement in today's treatment of PsA. Musculoskeletal inflammatory involvement was more prominent than psoriatic skin involvement. Only a few patients fulfilled the DAPSA, PASDAS, and CPDAI remission criteria, and about a quarter fulfilled the MDA criteria. Considerably fewer patients fulfilled PsA-specific remission criteria versus non-PsA specific remission criteria. Still, patient satisfaction was good and PASI and DLQI were low.

The impact of PASI 75 and PASI 90 on quality of life in moderate to severe psoriasis patients

BACKGROUND

It is well known that psoriasis significantly impacts patients' quality of life (QoL). With the introduction of improved treatment modalities with biologic agents, more patients with moderate to severe psoriasis are able to achieve better results as measured by the Psoriasis Area and Severity Index (PASI). PASI 75 indicates a 75% or greater reduction in PASI scores from baseline and is indicative of excellent disease improvement. With newer biologic agents such as secukinumab, ixekizumab and brodalumab, patients are now capable of achieving PASI 90, introducing additional clinical decisions for physicians when considering treatment options. However, little is known regarding how the difference between achieving PASI-75 versus PASI-90 impacts patients' QoL.

OBJECTIVES

The purpose of this study was to compare how achieving PASI 75 versus PASI 90 impacts QoL for patients with moderate to severe plaque psoriasis by using validated psychometric instruments that have been widely used in both dermatologic and non-dermatologic settings.

METHODS

Two separate open-label clinical trials were conducted to specifically assess QoL in patients with moderate to severe psoriasis on adalimumab or ustekinumab over 24 weeks. In addition to clinical assessments of psoriasis, patients completed two surveys: The Psychological General Well-Being (PGWB) Index and the Dermatology Life Quality Index (DLQI). Changes in total PGWB score and DLQI score at weeks 12 and 24 compared to baseline were compared between groups achieving PASI 75 and PASI 90.

RESULTS

There was no statistically significant difference in PGWB scores between patients achieving PASI 75 and patients achieving PASI 90 in the adalimumab treatment group (week 12 p = .21, but there was at week 24 p = .05). There was a statistically significant difference in DLQI between the patients achieving PASI 75 and the patients achieving PASI 90 in the adalimumab treatment group at week 24 (p = .01), but not week 12 (p = .11). There was no statistically significant difference in PGWB scores between patients achieving PASI 75 and patients achieving PASI 90 in the ustekinumab treatment group (week 12 p = .11, week 24 p = .35). There was no statistically significant difference in DLQI between the patients achieving PASI 75 and the patients achieving PASI 90 in the ustekinumab treatment group at week 24 (week 12 p = .49, week 24 p = .11).

CONCLUSIONS

There has been tremendous attention surrounding newer biologic agents that can achieve PASI 90 and even PASI 100. Although the results are impressive with regard to physical improvement of psoriasis, there may not be a clinically significant difference in QoL when comparing patients who achieve PASI-75 versus PASI 90.
