Translating the Science of Quality of Life into Practice: What Do Dermatology Life Quality Index Scores Mean?

Patients' preferences for systemic treatment of atopic dermatitis: safety and efficacy count the most

BACKGROUND

The advent of biologics and janus kinase inhibitors has revolutionized treatment of atopic dermatitis (AD).

OBJECTIVE

To investigate preferences of patients with AD for attributes of currently approved systemic treatments and assess influencing factors.

METHODS

An online discrete choice experiment was conducted in patients with AD throughout Germany to analyze preferences for outcome (probability of (almost) clear skin at week 16, probability of significant itch improvement, time to onset of itch relief and type of side effects) and process attributes (application method and frequency of laboratory tests).

RESULTS

Participants (n = 182, 75.3% female) considered side effects (Relative Importance Score (RIS): 31.2), (almost) clear skin (RIS: 24.2) and probability of itch improvement (RIS: 16.0) most important. Application method (RIS: 14.4), time to onset of itch relief (RIS: 7.4) and frequency of laboratory tests (RIS: 6.8) were less relevant. Preferences were significantly influenced by sex, age, psychiatric comorbidity, current therapy and health-related quality of life according to multivariate regression analysis.

CONCLUSIONS

Participants attached great importance to safety and symptom control. However, preferences were also dependent on individual characteristics, underscoring the importance of personal counseling. Conjoined with medical considerations, patients' preferences have fundamental impact on shared decisions for treatment of AD.

Lebrikizumab monotherapy impacts on quality of life scores through improved itch and sleep interference in two Phase 3 trials

BACKGROUND

Lebrikizumab improved itch, interference of itch on sleep, and quality of life (QoL) in patients with moderate-to-severe atopic dermatitis (AD), in two Phase 3 trials at 16 weeks compared to placebo.

OBJECTIVES

We assess improvements in itch and sleep interference due to itch and their impact on QoL measurements after treatment.

METHODS

Data were analyzed from ADvocate1 (NCT04146363) and ADvocate2 (NCT04178967) in patients with moderate-to-severe AD. QoL was evaluated using Dermatology Life Quality Index (DLQI) at Week 16 in patients (>16 years of age) who were itch responders/non-responders (defined as ≥4-point improvement in Pruritus Numeric Rating Scale) or Sleep-Loss Scale responders/non-responders (defined as ≥2-point improvement in itch interference on sleep).

RESULTS

In ADvocate1 and ADvocate2, significantly greater proportions of itch responders had a clinically meaningful improvement in measures related to QoL (DLQI scores (0/1), ≤5 DLQI total score and ≥4-point DLQI improvement) compared to itch non-responders. In both studies, a significantly greater proportion of Sleep-Loss Scale responders, reported a DLQI score of (0/1), DLQI total score of ≤5 and DLQI improvement of ≥4 points compared to Sleep-Loss Scale non-responders.

CONCLUSIONS

Improvement in itch and sleep interference due to itch is associated with improvement in the QoL of patients after treatment with lebrikizumab for moderate-to-severe AD.

Minimally Invasive Open Bilateral Total Thyroidectomy Using Unilateral Neck Incision in Thyroid Cancer: Preliminary Surgical and Quality of Life Outcomes

PURPOSE

Thyroid cancer incidence has increased in recent decades, and thyroid surgery is continuously evolving in response to demands for postoperative comfort and cosmesis. This study aimed to introduce a new surgical method for minimally invasive open bilateral total thyroidectomy (MI-BTT) using a unilateral 2.5-3.0 cm neck incision. Furthermore, we reported the surgical outcomes and postoperative quality of life (QoL) using a validated Korean translated Dermatology Life Quality Index (DLQI) questionnaire.

MATERIALS AND METHODS

We retrospectively evaluated 41 Asian patients who underwent MI-BTT for low-risk papillary thyroid cancer by a single surgeon from March 2019 to December 2021.

RESULTS

A total of 4 male and 37 female patients were included. The mean age and body mass index were 46.2±10.1 years and 23.3±3.3 kg/m², respectively. The average tumor size was 1.1±0.6 cm, and 36 patients (87.8%) had bilateral cancer. Twenty-three (56.1%) patients had occult central lymph node (CLN) metastasis in the final pathologic report, with the mean number of dissected CLNs being 7.2±6.5. Gross capsular extension was found in 6 patients (14.6%). Moreover, 28 patients (68.3%) received additional treatment after surgery with low or high doses of radioactive iodine. The average serum-stimulated thyroglobulin value identified during treatment was 1.57±2.30 ng/mL. The mean operation time was 78.0±13.9 minutes, and postoperative complications included transient hypocalcemia (36.6%), transient hoarseness (24.4%), and seroma (2.4%). The mean total DLQI score was 2.73±0.78, indicating a small effect on QoL.

CONCLUSION

MI-BTT is a novel, safe, and feasible technique to improve patient satisfaction for surgical scars and QoL.

Chronic Spontaneous Urticaria: Quality of Life and Economic Impacts

This study focuses on quality of life (QoL) assessment in chronic urticaria, delving into tools, disease-specific measures, and its profound impact. With expanding therapeutic options, understanding QoL becomes crucial. QoL measures often involve comparisons of patient-reported outcomes in addition to quantitative measures of disease control. Emerging tools include the Urticaria Activity and Impact Measure, which may provide a balanced evaluation. In addition to discussions of the various QoL measures, the psychological impact of chronic urticaria are highlighted, covering emotional burden, stress, and psychiatric comorbidities. Finally, the economic impacts reveal escalating health care costs and cost-effectiveness considerations of therapies like omalizumab.

Internalized stigma, disease severity, quality of life, anxiety and depression in axillary hyperhidrosis

BACKGROUND

Axillary hyperhidrosis (AH) is characterized by excessive underarm sweating. It is a chronic autonomic disorder that can lead to social embarrassment, impaired quality of life (QoL), anxiety and depression. Internalized stigma (IS), defined as the acceptance of negative societal attitudes and stereotypes about an individual's illness, has not been previously studied in AH. The aim of this study was to evaluate the level of IS in patients with AH and the relationships between IS, disease severity, quality of life, anxiety, and depression.

PATIENTS AND METHODS

One hundred and four patients with AH were included in the study. Demographic and clinical characteristics of the patients were recorded. The Hyperhidrosis Disease Severity Scale (HDSS) was used to define disease severity. Assessment was made using the Internalized Stigma Scale (ISS) (between 29 and 116, the higher the score the greater the stigma), Hospital Anxiety and Depression Scale (HADS) and Dermatology Life Quality Index (DLQI).

RESULTS

The mean age of the patients was 34.1 ± 10.9 years. The HDSS grade was mostly moderate to severe. The mean ISS score was 57.5 ± 6.5. Median HADS scores were 7 [interquartile range (IQR) 2-12] and 5 [IQR 2-10], respectively. HADS scores ≥ 8 were observed respectively in 39.4% and 8.7% of patients. The median DLQI score was 14 [IQR 4-24]. A DLQI score ≥ 11 was observed in 75% of patients. Significant correlation was found between ISS score and HDSS (r = 0.445, p < 0.001), HADS-A (r = 0.455, p < 0.001), DLQI (r = 0.478, p < 0.001) scores and symptom duration (r = 0.207, p = 0.035). The relationship between ISS and HADS depression scores was not statistically significant.

CONCLUSION

IS is common in patients with AH. Disease severity, symptom duration and anxiety increased IS. Patient's quality of life is reduced in AH.

Quality of life measurement in assessing treatment effectiveness in urticaria: European experts position statement

In this study, the European Academy of Dermatology and Venereology (EADV) Task Forces on Quality of Life and Patient-Oriented Outcomes and Urticaria and Angioedema has examined the Health-Related Quality of Life (HRQoL) measurement in the treatment of urticaria. The Dermatology Life Quality Index was the most frequently used HRQoL instrument in clinical trials on urticaria. Many reports of clinical trials of urticaria gave no exact numeric results related to HRQoL changes, making clear conclusions and comparisons with other studies impossible. The interpretation of HRQoL impairment data is more difficult when assessed by instruments without severity stratification systems. The minimal clinically significant difference (MCID) is a more clinically oriented and relevant parameter than depending on statistically significant changes in HRQoL scores. Therefore, using HRQoL instruments with established MCID data in clinical trials and clinical practice is preferred.

Lebrikizumab Improves Quality of Life and Patient-Reported Symptoms of Anxiety and Depression in Patients with Moderate-to-Severe Atopic Dermatitis

INTRODUCTION

Atopic dermatitis (AD) is a chronic inflammatory skin disease for which signs and symptoms have a negative impact on a patient's quality of life (QoL) and mental health. Here, we assess the impact of lebrikizumab on QoL and mental health after 16 weeks of treatment in patients with moderate-to-severe AD.

METHODS

Data were analyzed over 16 weeks from two separate phase 3, randomized, placebo-controlled, monotherapy trials (ADvocate1 and ADvocate2). Patient-reported outcomes were assessed using the following measures: Dermatology Life Quality Index (DLQI), EQ-5D-5L visual analogue scale (VAS), EQ-5D-5L index scores (UK and US), Patient-Reported Outcomes Measurement Information System (PROMIS) Anxiety, and PROMIS Depression.

RESULTS

Treatment with lebrikizumab 250 mg every 2 weeks in two studies led to statistically significant improvements (based on nominal p values) versus placebo in DLQI since week 4 (the first timepoint assessed) for the following measures: change from baseline in DLQI total score (ADvocate1 - 7.8 vs - 2.8; ADvocate2 - 7.3 vs - 3.9), proportion of patients with DLQI ≥ 4-point improvement (ADvocate1 69.5% vs 36.2%; ADvocate2 60.5% vs 42.6%), DLQI total score ≤ 5 (ADvocate1 36.7% vs 8.8%; ADvocate2 29.6% vs 10.8%), and DLQI (0, 1) (ADvocate1 12.3% vs 1.7%; ADvocate2 9.2% vs 1.7%). Improvements in DLQI measures, EQ-5D-5L index scores (UK and US), and EQ-5D-5L VAS were sustained through week 16. Additionally, lebrikizumab improved PROMIS Anxiety and PROMIS Depression scores, and improvements were higher in patients with at least a mild score (≥ 55) versus placebo for PROMIS Anxiety (ADvocate1 - 7.43 vs - 1.51; ADvocate2 - 4.95 vs - 0.82) and PROMIS Depression (ADvocate1 - 7.42 vs - 2.46; ADvocate2 - 4.28 vs - 2.00).

CONCLUSIONS

Treatment with monotherapy 250 mg lebrikizumab for 16 weeks provided clinically meaningful improvements in outcomes related to QoL and mental health for patients with moderate-to-severe AD. Lebrikizumab-treated patients reported improvements in DLQI as early as week 4, the first measure since baseline.

Effectiveness of calcipotriol/betamethasone dipropionate aerosol foam in patients with small versus large plaque psoriasis in routine practice in South Korea

Small plaque psoriasis is the typical form of chronic plaque psoriasis affecting adults in South Korea. The effectiveness of calcipotriol/betamethasone dipropionate (Cal/BD) aerosol foam for large and small psoriasis plaques has not previously been examined. We performed a post hoc analysis of a recent, 4-week observational study of Cal/BD aerosol foam use in routine clinical practice in South Korea. Investigator Global Assessment response ([IGA] 0/1 at week 4), Patient Global Assessment response ([PaGA] 0/1 at week 4), change in Psoriasis Area and Severity Index (PASI), changes in psoriasis symptom scores, change in the Dermatology Life Quality Index (DLQI), and the proportion of patients achieving DLQI ≤5 were analyzed for patients with small (≤5 cm; n = 131) or large (>5 cm; n = 35) baseline plaque size. IGA response rates were similar for patients with small and large plaques (59.5% and 51.4% respectively). Similarly, there was no significant difference between the small and large groups in mean change in PASI (-2.20 vs -3.34), the proportions of patients with DLQI ≤5 (62.3% vs 54.3%) or PaGA 0/1 (29.2% vs 40.0%). Mean improvements in DLQI (-4.04 vs -6.20) and in psoriasis symptoms including itching (-1.50 vs -2.83), sleep loss (-0.67 vs -1.89), dryness (-1.57 vs -2.97), scaling (-1.21 vs -3.57), and redness (-1.17 vs -3.11) were greater in patients with large plaques than those with small plaques. Itching and DLQI differences were not statistically significant after adjustment for baseline characteristics. Stratification by body surface area affected eliminated statistically significant differences between the groups for most outcomes. In conclusion, this analysis suggests that Cal/BD aerosol foam is an effective, well-accepted treatment for adult patients with the small plaques typical of chronic plaque psoriasis in South Korea, as well as for those with large plaques.

[Quality of life and sleep quality in patients with chronic pruritus]

Pruritus is defined as a symptom that leads to scratching. Clinically, a heterogeneous group of clinical pictures of different etiology must be considered. Pruritus is characterized by varying intensity and duration. Many patients and/or their social environment, which is influenced by this, cite the impact on sleep quality as an accompanying main symptom. The patient's quality of life is affected depending on the severity of the pruritus and often leads to comorbidity such as depressive disorders or sleep disorders as well as to an impact on psychosocial well-being if it becomes chronic. To date, in addition to the medical history, the established examination methods have been the determination of the disease burden by assessing disease activity, e.g., with validated disease-specific scores, plus the assessment of quality of life using a dermatological quality of life index (DLQI). The latest studies show that this is by no means sufficient to determine the severity of disease and, as a result, to identify adequate treatment options.

Six-Month Real-World Study to Assess the Effectiveness of Ixekizumab After Switching from IL-23 Inhibitors and Other Biologic Therapies: The CorEvitas Psoriasis Registry

BACKGROUND

Prior work showed that patients from the CorEvitas Psoriasis Registry who had previously failed a prior biologic and then initiated ixekizumab demonstrated improvements in disease severity and patient-reported outcomes after 6 months. However, newer therapies such as interleukin-23 inhibitors (IL-23i) were not considered. Here, with more recent data including IL-23i, 6-month effectiveness of ixekizumab following a switch from any biologic was assessed as well as whether 6-month effectiveness of ixekizumab was impacted by prior biologic class.

METHODS

We included CorEvitas Psoriasis Registry patients who initiated ixekizumab after discontinuing another biologic therapy and had a corresponding 6-month follow-up visit following ixekizumab initiation (N = 743, 2016-2023). Immediate prior biologic class was categorized as tumor necrosis factor inhibitor (TNFi) or interleukin-12/23 inhibitors (IL-12/23i, n = 405), non-ixekizumab interleukin-17i (IL-17i, n = 237), or IL-23i (n = 101). Adjusted mean changes in body surface area (BSA), Dermatology Life Quality Index (DLQI), itch, and skin pain were calculated for prior biologic class groups using analysis of covariance (ANCOVA). Proportions achieving ≥ 75%, ≥ 90%, and ≥ 100% improvement in Psoriasis Area and Severity Index (PASI75, PASI90, and PASI100, respectively), Investigator's Global Assessment (IGA) 0/1, and DLQI 0/1 were calculated for all patients and compared among prior biologic classes via relative risks (RRs) and 95% confidence intervals (CIs) using multivariable modified Poisson regression.

RESULTS

Mean improvements in BSA, DLQI, itch, and skin pain, were 7.6, 3.6, 23.3, and 16.7, respectively, for ixekizumab patients who switched from TNFi or IL-12/23i (all p < 0.05); 6.8, 3.3, 19.6, and 14.1, respectively, for those who switched from non-ixekizumab IL-17i (all p < 0.05); and 7.8, 3.4, 22.2, and 12.8, respectively, for those who switched from IL-23i (all p < 0.05). Overall, 54%, 41%, and 31% of ixekizumab initiators achieved PASI75, PASI90, and PASI100, respectively, 50% maintained or achieved IGA 0/1, and 48% maintained or achieved DLQI 0/1. The prior TNFi or IL-12/23i group was 31% more likely to achieve PASI100 (RR = 1.31, 95% CI 1.01, 1.69) and 32% more likely to maintain or achieve IGA 0/1 (RR = 1.32, 95% CI 1.11, 1.57), but not significantly more likely to achieve PASI90. The prior IL-23i group was 45% more likely to achieve PASI90 (RR = 1.45, 95% CI 1.10, 1.91), 55% more likely to achieve PASI100 (RR = 1.55, 95% CI 1.12, 2.13), and 39% more likely to maintain or achieve IGA 0/1 (RR = 1.39, 95% CI 1.12, 1.73) compared to the prior non-ixekizumab IL-17i group. Achievement of PASI75 and DLQI 0/1 was consistent across the prior TNFi or IL-12/23i, IL-23i, and non-ixekizumab IL-17i groups.

CONCLUSIONS

These updated findings with IL-23i data reaffirm that patients with psoriasis who switch to ixekizumab after discontinuing another biologic demonstrate improvement in disease severity and patient-reported outcomes at 6 months in real-world settings. Compared to patients who switched from another IL-17i, patients who switched class from a TNFi or IL-12/23i were more likely to achieve PASI100 and IGA 0/1, and patients who switched class from an IL-23i were more likely to achieve PASI90 in addition to PASI100 and IGA 0/1.

Worst Itch Numeric Rating Scale for Prurigo Nodularis: A Secondary Analysis of 2 Randomized Clinical Trials

Importance

Prurigo nodularis (PN) is a debilitating skin disease characterized by the hallmark symptom of chronic itch; the intensity of itch in PN was assessed using the Worst Itch Numeric Rating Scale (WI-NRS) to evaluate the primary efficacy end point of 2 recent phase 3 studies of dupilumab treatment for PN.

Objective

To validate the psychometric properties and to determine the clinically meaningful improvement threshold for WI-NRS in patients with moderate to severe PN.

Design, Setting, and Participants

In this secondary analysis of the PRIME and PRIME2 trials, content validity of WI-NRS was assessed through in-depth patient interviews. Psychometric assessments used pooled data from masked, intention-to-treat (ITT) patients with PN from randomized, double-masked, and placebo-controlled studies. Psychometric assessments included test-retest reliability, construct validity, known-groups validity, and sensitivity to change in adult patients with moderate-to-severe PN. Thresholds for meaningful within-patient improvement in the WI-NRS score were determined using anchor and distribution-based approaches. Data were analyzed after completion of each study, December 2019 to November 2021 for PRIME and January 2020 to August 2021 for PRIME2.

Exposures

Dupilumab (300 mg) or placebo subcutaneously every 2 weeks for 24 weeks.

Main outcomes and measures

WI-NRS score at specified time points up to 24 weeks after randomization.

Results

A total of 20 patients were included across the 2 studies (mean [SD] age, 49.3 [17.2] years; 11 female [55%]); 311 patients were included in the pooled intention-to-treat analysis (mean [SD] age, 49.5 [16.1] years; 203 female [65.3%]). The WI-NRS questions (20 of 20 patients), recall period (19 of 20 patients), and response scale (20 of 20 patients) were easy to understand and relevant for patients with PN. Adequate test-retest reliability was observed between screening and baseline (intraclass correlation coefficient = 0.72, using Patient Global Impression of Severity [PGIS] to define stable patients). Convergent and discriminant validity was supported by moderate to strong correlations (absolute r range = 0.34-0.73) with other conceptually related measures and weaker correlations (absolute r range = 0.06-0.32) with less-related measures, respectively. WI-NRS was sensitive to change, as demonstrated by differences in change from baseline among groups (per PGIS change and PGI of Change [PGIC]). Using anchor-based approach with PGIS and PGIC, the clinically meaningful improvement threshold was 4 points (range, 3.0-4.5), which was also supported by distribution-based methods.

Conclusion and Relevance

This study found that WI-NRS may be a fit-for-purpose instrument to support efficacy end points measuring the intensity of itching in adults with PN.

Quality of life measurement in urticaria: Position statement of the European Academy of Dermatology and Venereology Task Forces on Quality of Life and Patient-Oriented Outcomes and Urticaria and Angioedema

The European Academy of Dermatology and Venereology (EADV) Task Forces on quality of life (QoL) and patient-oriented outcomes and on urticaria and angioedema recommendations for the assessment of Health-related (HR) QoL in all patients with urticaria in research and practice are as follows: to use the DLQI for adults and the CDLQI for children as dermatology-specific and the CU-Q2oL as a disease-specific HRQoL instruments in urticaria; to use generic instruments to provide comparison of data on urticaria with non-dermatologic diseases, or to compare with healthy volunteers or the general population; to select validated HRQoL instruments with appropriate age limits; to present exact numeric data for HRQoL results; correct title of any HRQoL instrument should be used, along with its correct abbreviation and the reference to its original publication, where possible. The EADV TFs discourage the use of non-validated HRQoL instruments and modified HRQoL instruments that have not undergone standard validation.

Impact of residual skin lesions and previous biologic treatment failure on patient-reported outcomes in patients with psoriasis receiving biologic treatment

Recent advances in biologic treatments have made clear skin a realistic treatment goal for psoriasis. However, clear skin may not uniformly translate to an absence of impact on patients' quality of life. This retrospective observational study aimed to elucidate the factors influencing patient-reported outcomes in patients with psoriasis who have demonstrated successful clinician-reported outcomes on using biologics. A total of 96 patients who have achieved a ≥75% improvement in Psoriasis Area and Severity Index (PASI) scores with ≥6 months of biologic treatment were included. Their median PASI score was 0.4, with 37.5% having achieved PASI 100 (clear skin). Furthermore, 47.9% reported no impact of psoriasis on their quality of life (Dermatology Life Quality Index [DLQI] score 0 or 1), while 52.1% reported a negative impact (DLQI score ≥2). Notably, 28.1% of the participants had a history of biologic treatment failure, defined as the inability to achieve or sustain a 75% PASI improvement with the previously used biologic agent. Multivariable logistic regression analysis revealed a positive association between achieving PASI 100 and reporting no impact of psoriasis on quality of life (adjusted odds ratio [aOR] 3.88, 95% confidence interval [CI] 1.49-10.91, P = 0.007). Conversely, prior biologic treatment failure was negatively associated with reporting no impact of psoriasis on quality of life (aOR 0.13, 95% CI 0.02-0.65, P = 0.023). Furthermore, among patients with clear skin, those with experience of previous biologic treatment failure reported significantly lower quality of life than those without such experience (P = 0.033). In conclusion, minimal residual skin lesions and prior biologic treatment failure were associated with poorer patient-reported outcomes in patients with psoriasis. Opting for a biologic agent with the highest predicted efficacy, rather than pursuing a "step-up" approach with a higher possibility of treatment failure, may be a more suitable strategy in the biologic treatment of psoriasis.

Botulinum toxin A versus microwave thermolysis for primary axillary hyperhidrosis: A randomized controlled trial

Background

Botulinum toxin A (BTX) and microwave thermolysis (MWT) represent 2 treatment modalities for axillary hyperhidrosis with different procedural and efficacy profiles.

Objective

To compare long-term outcomes following BTX vs MWT treatment of axillary hyperhidrosis.

Methods

A prospective, randomized, within-patient, controlled trial, treating axillary hyperhidrosis with contralateral BTX and MWT. Objective sweat measurement and patient-reported outcome measures for sweat and odor were collected at baseline, 6-month and 1-year follow-up (6M/1YFU). Hair reduction and patient treatment preference was also assessed.

Results

Sweat reduction was significant (all P <.01) for both interventions throughout the study. Objectively, sweat reduction was equal at 1-year FU (ΔP =.4282), but greater for BTX than MWT at 6-month FU (ΔP =.0053). Subjective sweat assessment presented comparable efficacy (6MFU: ΔP =.4142, 1YFU: ΔP =.1025). Odor reduction was significant (all P <.01) following both interventions, whereas only sustaining for MWT (6MFU: ΔP =.6826, 1YFU: ΔP =.0098). Long-term, hair reduction was visible after MWT, but not BTX (ΔP ≤.0001), and MWT was preferred by the majority of patients (76%).

Limitations

The intrinsic challenges in efficacy assessment.

Conclusion

This study exhibited BTX and MWT with similar sweat reduction, but distinguishable odor and hair reduction at 1-year FU. These findings support individualized treatment approaches for axillary hyperhidrosis based on patient-specific symptoms and preferences.

Ixekizumab Demonstrates Rapid and Consistent Efficacy for Patients with Psoriatic Arthritis, Regardless of Psoriasis Severity

INTRODUCTION

Skin involvement in patients with psoriatic arthritis (PsA) worsens the severity and burden of disease. Ixekizumab (IXE), a selective interleukin (IL)-17A antagonist, was compared to placebo (PBO) in the SPIRIT-P1 (NCT01695239) and SPIRIT-P2 (NCT02349295) studies in patients with PsA and evidence of plaque psoriasis. This post hoc analysis reports musculoskeletal, skin, and nail outcomes through week 24 in patients from SPIRIT-P1 and SPIRIT-P2, stratified by mild, moderate, or psoriasis at baseline.

METHODS

This post hoc analysis pooled patients from SPIRIT-P1 and SPIRIT-P2 who were randomly assigned to PBO or IXE 80 mg every 4 weeks (Q4W) or every 2 weeks (Q2W). Efficacy outcomes were analyzed through week 24 by baseline psoriasis severity, defined by percent body surface area (BSA) affected; mild = BSA < 3%, moderate = 3% ≤ BSA ≤ 10%, severe = BSA > 10%. The primary outcomes assessed were the proportion of patients achieving American College of Rheumatology (ACR)20, ACR50, and ACR70 responses. Secondary outcomes included musculoskeletal, disease activity, skin and nail, and health-related quality-of-life measures.

RESULTS

Similar proportions of patients achieved ACR20/ACR50/ACR70 over time across all severity subgroups and treatment arms. More than one-third of IXE-treated patients achieved ACR20 at week 4, or ACR50 at week 24, with no significant differences according to psoriasis severity at baseline. Disease activity outcomes were similar through week 24 with both IXEQ4W and IXEQ2W, regardless of psoriasis severity at baseline. There were no significant differences over 24 weeks in the proportions of IXE-treated patients with mild, moderate, or severe baseline psoriasis who achieved Minimal Disease Activity (MDA). Across all severity subgroups, IXE demonstrated Psoriasis Area Severity Index 100 response as early as week 4, and approximately one-third of IXE-treated patients achieved total skin clearance at week 24.

CONCLUSION

IXE demonstrated rapid and consistent efficacy in joint, skin, and nail for patients with PsA, regardless of baseline psoriasis severity.

Belgian Patients of the European Registry for Hidradenitis Suppurativa (ERHS-Be): Data, Scores, and Phenotypes since 2015

INTRODUCTION

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease, characterized by painful and recurrent lesions in apocrine gland-bearing skin areas. It is a heterogeneous disease, which makes assessment and data collection difficult. Questionnaires with detailed items, such as the Belgian European Registry for Hidradenitis Suppurativa (ERHS-Be), are useful to study HS and its associated comorbidities. The aim of this registry was to uncover new factors associated with HS and understand HS patients' clinical profiles and efficacy of treatments.

MATERIAL AND METHODS

The ERHS-Be registry is based on questionnaires, with sections for sociodemographic data, medical and HS history, clinical examination, and treatment plan. It allows identification of different clinical phenotypes and automatic calculation of severity scores.

RESULTS

At present, 606 patients are included in the ERHS-Be (67% women, 33% men). The mean age at the first visit is 38.5 years. Tobacco use is present in 72.6% of patients. A family history of HS is noted in 42% of patients. Comorbidities are documented in this cohort: depression is present in 43.8% of patients, arthritis in 27.8%, obesity in 31.5%, hypertension in 10.6%, diabetes mellitus in 6.4%, and dyslipidemia in 12.4%. Moreover, 7.7% of patients suffer from IBD and 27.4% have a pilonidal sinus. History of severe acne is found in 32.1% of patients and psoriasis in 9.3%. Thirteen percent of women in our cohort suffer from polycystic ovarian syndrome. Severity of disease is quantified in 533 patients: for instance, Hurley I, II, and III scores proportions are, respectively, 32.3%, 52.7%, and 15%, while the mean IHS4 score is 5.2. This registry also enables determination of relative phenotype proportions in our cohort, according to different classifications.

CONCLUSION

The ERHS-Be questionnaires allow systematic and larger data collection, including detailed comorbidities, phenotypes, and severity of disease. Analysis of this large database will contribute to a better understanding and management of HS, at a time where new therapeutic options are becoming available.

Effectiveness of Ixekizumab in Chinese Patients with Moderate-Severe Plaque Psoriasis with Special Area Involvement: Subanalysis of a Prospective, Multicenter, Observational Real-World Study

INTRODUCTION

Ixekizumab, a monoclonal antibody against interleukin-17A, demonstrated effectiveness in the treatment of psoriasis in a Chinese real-world study that was consistent with previous randomized controlled trials. Here, we report further analyses from this study to explore the effectiveness of ixekizumab for treating patients with psoriasis and the involvement of special body areas (scalp, nail, joint, palmoplantar, or genital areas).

METHODS

A multicenter, prospective, observational, single-arm, post-marketing surveillance study was conducted in patients aged ≥ 18 years with moderate-to-severe plaque psoriasis and prescribed with ixekizumab in 26 Chinese hospitals. Psoriasis Area and Severity Index (PASI) and Dermatology Life Quality Index (DLQI) scores were compared between patients with versus without psoriasis in special body areas in the overall study population and across subgroups by body area.

RESULTS

In total, 612 patients were included. At baseline, most patients (93.6%) had psoriasis involvement in at least one special body area. Overall, patients with psoriasis in special body areas reported a worse quality of life (QoL) than those without. Patients with versus without psoriasis in special body areas achieved a comparable mean reduction from baseline in PASI score (10.9 vs. 9.2 at week 2, and 16.9 vs. 14.7 at week 12, respectively) and DLQI score (6.0 vs. 4.4 at week 2, and 9.9 vs. 7.5 at week 12, respectively); a similar proportion of patients also achieved PASI 50 at week 2, and PASI 75 and PASI 90 at week 12, and a DLQI (0/1) at weeks 2 and 12. Several significantly different results were reported between subgroups, the majority of which favored patients with special body area involvement.

CONCLUSION

Most patients had psoriasis involvement in a special body area which was associated with worse QoL. Ixekizumab is similarly effective in reducing disease severity and improving QoL in patients with plaque psoriasis across different special body areas.

Psychosocial impact of androgenetic alopecia on men: A systematic review and meta-analysis

The adverse psychosocial impact of androgenetic alopecia (AGA) is often framed as an essential motivation for developing efficacious treatments to halt hair loss or promote regrowth, especially since AGA is common among men but does not result in physically harmful or life-limiting consequences. Yet, empirical evidence documenting the impact of AGA on men's psychological wellbeing and quality of life is patchy and has not previously been subject to systematic review. This systemic review and meta-analyses aim to integrate and evaluate evidence regarding the psychosocial impact of AGA on men. A database and manual reference search identified English-language articles which reported: 1) empirical research; of ii) psychosocial distress (mental health, depression, anxiety, self-esteem, or quality of life); and iii) data separately for male AGA participants. Screening of 607 articles resulted in 37 (6%) for inclusion. PRISMA guidelines, the (modified) AXIS quality assessment tool, and independent extraction were deployed. Heterogeneity in measures and study aims, moderate study quality (M = 7.37, SD = 1.31), probable conflicts of interest (78%) and biased samples (68%) suggest that results should be treated cautiously. Meta-analyses revealed no impact on depression (pooled M = 8.8, 95% CI = 6.8-10.8) and moderate impact on quality of life (pooled m = 9.12, 95% CI = 6.14-12.10). Men with AGA were found to have average or better mental health compared to those without AGA. Overall, there was limited evidence of a severe impact on mental health and quality of life for men experiencing hair loss, with most studies evidencing (at best) a moderate impact. Good dermatological care includes accurately educating about the psychosocial impact of AGA on men, taking care not to overstate levels of distress, and screening for distress using validated measures which have clear clinical thresholds.

Patient-Reported Burden of Severe Alopecia Areata: First Results from the Multinational Alopecia Areata Unmet Need Survey

Purpose

Alopecia areata (AA) is an autoimmune disease characterized by hair loss that has significant psychosocial implications. This study aims to describe the patient-reported burden of severe AA, coping mechanism and information needs using data from the multinational AA Patient Satisfaction and Unmet Need Survey.

Patients and Methods

Participants with current or previous ≥50% scalp hair loss (n = 747) were recruited from 11 countries and completed a web-based survey that assessed demographics, clinical characteristics, disease burden and psychosocial impact. Data were stratified according to sex, current age, disease duration and current severity of scalp hair loss.

Results

The mean (SD) age of participants was 43.8 (7.1) years, 55.3% were women, and 63.5% reported AA symptoms within 6 months of diagnosis. Most participants had black or brown hair (88.4%), reported a disease duration of 2 years or more (75.6%) and had current scalp hair loss of ≥50% (87.4%). Severe hair loss also extended to eyebrow (46.9%), eyelash (48.7), beard (61.5%) and body hair (73.2%). Participants commonly reported comorbidities such as anxiety (26.1%), depression (18.1%) and sleep problems (28.1%). The Dermatology Life Quality Index revealed a severe impact on quality of life; 86.2% of participants scored >10. Mental health/mood was significantly affected; 55.8% of participants reported a substantial impact. Long-term effects included decreased self-esteem (32.9%), poor mental health (28.1%) and challenges in day-to-day activities (27.2%). Information needs were centered around treatment expectations, mental health, and available treatment options. More severe symptoms and a greater daily impact were reported by women and those with a longer disease duration.

Conclusion

The study emphasizes the substantial burden, including impaired quality of life and psychological well-being, of severe AA on the lives of surveyed participants. The findings highlight the importance of comprehensive disease management strategies that address both physical and psychosocial aspects of AA.

How to use the Harmonising Outcome Measures for Eczema Core Outcome Set for atopic dermatitis trials: a users' guide

BACKGROUND

The Harmonising Outcome Measures for Eczema (HOME) initiative has agreed upon the Core Outcome Set (COS) for use in atopic dermatitis (AD) clinical trials, but additional guidance is needed to maximize its uptake.

OBJECTIVES

To provide answers to some of the commonly asked questions about using the HOME COS; to provide data to help with the interpretation of trial results; and to support sample size calculations for future trials.

METHODS AND RESULTS

We provide practical guidance on the use of the HOME COS for investigators planning clinical trials in patients with AD. It answers some of the common questions about using the HOME COS, how to access the outcome measurement instruments, what training/resources are needed to use them appropriately and clarifies when the COS is applicable. We also provide exemplar data to inform sample size calculations for eczema trials and encourage standardized data collection and reporting of the COS.

CONCLUSIONS

By encouraging adoption of the COS and facilitating consistent reporting of outcome data, it is hoped that the results of eczema trials will be more comprehensive and readily combined in meta-analyses and that patient care will subsequently be improved.

What do Hyperhidrosis Quality of Life Index (HidroQoL©) scores mean? Transferring science into practice by establishing a score banding system

BACKGROUND

The Hyperhidrosis Quality of Life Index (HidroQoL©) is a measure of quality of life (QoL) impacts in hyperhidrosis (HH).

OBJECTIVES

We aimed to establish score banding systems for the HidroQoL total score for specific contexts representing different severity/impact categories by using the Dermatology Life Quality Index (DLQI) and the Hyperhidrosis Disease Severity Scale (HDSS) as anchors, including data from 357 patients from a phase III clinical trial.

METHODS

We used the HDSS, the established DLQI score bands and two single items (items 5 and 7) of the DLQI as anchors for the creation of banding systems for the HidroQoL. These anchors were chosen via consensus among an expert group according to relevance to patient experience. Due to the distribution of the HDSS and the single DLQI item 7, receiver operating characteristic curves were computed in order to create an optimal cut-off value of the HidroQoL total score. For the DLQI banding system and the single DLQI item 5, we created a banding system for the HidroQoL based on the distribution of their different categories.

RESULTS

A score of 30 and greater is proposed as the cut-off value for sweating that 'always interferes in daily activities', based on the HDSS as anchor. In terms of overall skin QoL effects, score bands of 0-6, 7-18, 19-25, 26-32 and 33-36 represent 'no effect', 'small effect', 'moderate effect', 'very large effect' and 'extremely large effect' on the patient's life, respectively.

CONCLUSIONS

In this study, we propose different banding systems for four different contexts: skin-specific QoL (DLQI banding), HH severity (HDSS), working and studying (single DLQI item 7) and social and leisure activities (single DLQI item 5). These banding systems and cut-off values can be used in clinical research and practice to place the patients in different severity categories.

Botulinum Toxin A and B for Palmoplantar Hyperhidrosis

INTRODUCTION

Hyperhidrosis is characterized by unpredictable, uncontrollable and excessive sweating. It occurs at rest and is not related to temperature. Hyperhidrosis is a common disorder that has a negative impact on quality of life (QoL). The aim of this quality assurance study was to investigate how treatment of palmoplantar hyperhidrosis with botulinum toxin A (BTX-A) and botulinum toxin B (BTX-B) led to improvement of patient reported outcome measures related to QoL.

METHODS

A total of 35 patients with palmar and/or plantar hyperhidrosis who had received BTX-A (Dysport®) and BTX-B (NeuroBloc®) for palmar hyperhidrosis and BTX-B for plantar hyperhidrosis were included in this study. In total, palms were injected with a median dose (low to high) of 400 (100-550) units BTX-A and a median dose (low to high) of 200 (200-500) units. BTX-B was used in the thenar and hypothenar areas to avoid muscle weakness. In the soles a total median dose (low to high) of 600 (475-1000) units BTX-B was injected.

RESULTS

At follow-up 2 weeks post-treatment, patients' Dermatology Life Quality Index (DLQI) score improved from 13 to 2 (p < 0.001).

CONCLUSION

We found that BTX-A and BTX-B treatment for palmar hyperhidrosis and BTX-B treatment for plantar hyperhidrosis led to a substantial improvement of QoL.

The impact of genital lichen sclerosus in men and women on quality of life: a prospective cohort study

Background

Genital lichen sclerosus (LS) is a chronic inflammatory skin disorder that affects both sexes of all ages. The clinical characteristics include erosions, redness, and white plaques with atrophic skin, with symptoms such as pruritus, pain, dysuria, and dyspareunia.

Objective

This prospective cohort study aimed to assess quality of life (QoL) in men and women with genital LS, both before and after treatment, using the Dermatology Quality of Life Index (DLQI) questionnaire.

Methods

Patients diagnosed with genital LS were enrolled continuously in the study and were asked to complete the DLQI questionnaire before treatment and again after individualized treatment 12 weeks apart.

Results

This study included 136 patients (48 females and 88 males) diagnosed with genital LS, with a median age of 62 years (range 18-86). The results showed a statistically significant decrease (P < .001) in DLQI score before treatment (median 6.0 [interquartile range (IQR), 1.0-11.0]) compared to after treatment (median 2.0 [IQR, 0.0-4.0)]. In males and females, the median DLQI scores before treatment were 3.0 (IQR, 0.0-10.0) and 8.0 (IQR, 4.5-11.5), respectively, and after treatment were 1.0 (IQR, 0.0-3.0) and 4.0 (IQR, 0.0-9.0), respectively. Females scored significantly higher (P < .001) than males.

Limitations

The study's limited generalizability stems from a small sample size of 136 patients, potentially restricting the application of findings to a broader population with genital lichen sclerosus. Additionally, the 12-week follow-up period may not adequately capture the long-term effects of interventions on quality of life. Reliance on self-reported data through the DLQI questionnaire introduces the possibility of bias, as participants may not accurately represent their symptoms and quality of life. The absence of a control group hinders the ability to attribute observed changes solely to the treatment, and the lack of detail on specific interventions makes it challenging to assess the effectiveness of individualized treatment approaches. The wide age range among participants (18-86 years) introduces potential confounding variables, as different age groups may respond differently to treatment.

Conclusion

The study findings confirmed that individuals with genital LS experience a small decline in QoL, as observed in both males and females. This study also highlights that effective management of genital LS can significantly improve QoL in both sexes.

Atopic dermatitis (eczema) guidelines: 2023 American Academy of Allergy, Asthma and Immunology/American College of Allergy, Asthma and Immunology Joint Task Force on Practice Parameters GRADE- and Institute of Medicine-based recommendations

BACKGROUND

Guidance addressing atopic dermatitis (AD) management, last issued in 2012 by the American Academy of Allergy, Asthma and Immunology/American College of Allergy, Asthma and Immunology Joint Task Force, requires updating as a result of new treatments and improved guideline and evidence synthesis methodology.

OBJECTIVE

To produce evidence-based guidelines that support patients, clinicians, and other decision-makers in the optimal treatment of AD.

METHODS

A multidisciplinary guideline panel consisting of patients and caregivers, AD experts (dermatology and allergy/immunology), primary care practitioners (family medicine, pediatrics, internal medicine), and allied health professionals (psychology, pharmacy, nursing) convened, prioritized equity, diversity, and inclusiveness, and implemented management strategies to minimize influence of conflicts of interest. The Evidence in Allergy Group supported guideline development by performing systematic evidence reviews, facilitating guideline processes, and holding focus groups with patient and family partners. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach informed rating the certainty of evidence and strength of recommendations. Evidence-to-decision frameworks, subjected to public comment, translated evidence to recommendations using trustworthy guideline principles.

RESULTS

The panel agreed on 25 recommendations to gain and maintain control of AD for patients with mild, moderate, and severe AD. The eAppendix provides practical information and implementation considerations in 1-2 page patient-friendly handouts.

CONCLUSION

These evidence-based recommendations address optimal use of (1) topical treatments (barrier moisturization devices, corticosteroids, calcineurin inhibitors, PDE4 inhibitors [crisaborole], topical JAK inhibitors, occlusive [wet wrap] therapy, adjunctive antimicrobials, application frequency, maintenance therapy), (2) dilute bleach baths, (3) dietary avoidance/elimination, (4) allergen immunotherapy, and (5) systemic treatments (biologics/monoclonal antibodies, small molecule immunosuppressants [cyclosporine, methotrexate, azathioprine, mycophenolate, JAK inhibitors], and systemic corticosteroids) and UV phototherapy (light therapy).

Low prevalence of scabies and impetigo in Dakar/Senegal: A cluster-randomised, cross-sectional survey

BACKGROUND

Scabies, a parasitic infection caused by Sarcoptes scabiei var. hominis, is a public health problem with significant morbidity worldwide, particularly in low-resource countries. Impetigo, a complication of scabies infection, is a risk factor for sepsis, glomerulonephritis and possibly acute rheumatic fever. Currently, the majority of epidemiological data has been collected in rural populations in the Pacific with limited applicability to urban populations in sub-Saharan Africa, where scabies is also believed to be a problem. To inform future public health programs, more reliable information about the burden of disease is required.

METHODOLOGY/PRINCIPAL FINDINGS

In July/August 2022, we conducted a cross sectional, cluster-randomised, household survey in Pikine/Dakar using the 'International Association for the Control of Scabies (IACS)' criteria to diagnose scabies and impetigo. All participants underwent a standardised clinical examination by post-graduate dermatology students. For those diagnosed with scabies, an age-adapted 'Dermatology Life Quality Index (DLQI)' questionnaire was filled. We recruited and examined 1697 participants to detect 27 cases of scabies (prevalence: 1.6%, 95% CI 0.8-3.2), mostly in school aged children. Ten participants suffered from impetigo (prevalence: 0.6%, 95% CI 0.3-1.3), 5 of which were dually infected with scabies. Risk factors for scabies infection were young age, male gender and Koranic school attendance. Of those found to have scabies, in 7 out of 22 cases (31.8%) it had a large effect on their lives according to the DLQI questionnaires filled.

CONCLUSIONS/SIGNIFICANCE

This study adds to the mapping of the burden of scabies across Africa to support public health action. With a low prevalence of scabies that is concentrated amongst poor households and children attending Koranic schools, a focused public health approach targeting Koranic schools and poor households seems to be most appropriate in this community.

Solar urticaria: clinical characteristics, treatment effectiveness, long-term prognosis, and QOL status in 29 patients

Introduction

Solar urticaria (SU), a relatively rare skin inflammatory and photosensitivity disease, is often resistant to standard urticaria treatment. Quality of life (QOL) among SU patients has not been extensively explored. This study was performed to clarify the clinical features and effectiveness of therapies (e.g., hardening therapy) for SU and to determine QOL among SU patients.

Methods

The authors examined the characteristics, treatments, and QOL statuses of 29 Japanese SU patients using medical records and a questionnaire approach.

Results

Among 29 patients, H1 antihistamine therapy (H1) was effective in 22 (75.8%) patients. H2 antihistamine therapy (H2) was effective in three of seven (42.9%) patients. Ultraviolet radiation A (UVA) hardening therapy was effective in eight of nine (88.9%) patients. Visible light (VL) hardening therapy was ineffective in three of three patients. In one patient who underwent both UVA and VL hardening therapy, only UVA hardening therapy was effective. In the questionnaire, 18 patients (90%) reported some improvement compared with disease onset (four had complete remission, six had completed treatment although mild symptoms persisted, and eight were receiving treatment with moderate symptoms), whereas two patients reported exacerbation. Patients in complete remission had a mean disease duration of 4 years, whereas patients not in remission had a mean disease duration of 8.8 years. The mean Dermatology Life Quality Index (DLQI) score for the current status was 7.4. There was a correlation between DLQI and symptom/treatment status. However, neither DLQI and action spectra nor DLQI and treatments exhibited significant differences.

Discussion

The questionnaire revealed current QOL status and long-term prognosis in SU patients. Compared with disease onset, most patients showed improvement when assessed for this study. Both H1 and H2 should be attempted for all SU patients. UVA hardening therapy may be an option for SU patients with an action spectrum that includes UVA.

A systematic review of 454 randomized controlled trials using the Dermatology Life Quality Index: experience in 69 diseases and 43 countries

BACKGROUND

Over 29 years of clinical application, the Dermatology Life Quality Index (DLQI) has remained the most used patient-reported outcome (PRO) in dermatology due to its robustness, simplicity and ease of use.

OBJECTIVES

To generate further evidence of the DLQI's utility in randomized controlled trials (RCTs) and to cover all diseases and interventions.

METHODS

The methodology followed PRISMA guidelines and included seven bibliographical databases, searching articles published from 1 January 1994 until 16 November 2021. Articles were reviewed independently by two assessors, and an adjudicator resolved any opinion differences.

RESULTS

Of 3220 screened publications, 454 articles meeting the eligibility criteria for inclusion, describing research on 198 190 patients, were analysed. DLQI scores were primary endpoints in 24 (5.3%) of studies. Most studies were of psoriasis (54.1%), although 69 different diseases were studied. Most study drugs were systemic (85.1%), with biologics comprising 55.9% of all pharmacological interventions. Topical treatments comprised 17.0% of total pharmacological interventions. Nonpharmacological interventions, mainly laser therapy and ultraviolet radiation treatment, comprised 12.2% of the total number of interventions. The majority of studies (63.7%) were multicentric, with trials conducted in at least 42 different countries; 40.2% were conducted in multiple countries. The minimal clinically importance difference (MCID) was reported in the analysis of 15.0% of studies, but only 1.3% considered full score meaning banding of the DLQI. Forty-seven (10.4%) of the studies investigated statistical correlation of the DLQI with clinical severity assessment or other PRO/quality of life tools; and 61-86% of studies had within-group scores differences greater than the MCID in 'active treatment arms'. The Jadad risk-of-bias scale showed that bias was generally low, as 91.8% of the studies had Jadad scores of ≥ 3; only 0.4% of studies showed a high risk of bias from randomization. Thirteen per cent had a high risk of bias from blinding and 10.1% had a high risk of bias from unknown outcomes of all participants in the studies. In 18.5% of the studies the authors declared that they followed an intention-to-treat protocol; imputation for missing DLQI data was used in 34.4% of studies.

CONCLUSIONS

This systematic review provides a wealth of evidence of the use of the DLQI in clinical trials to inform researchers' and -clinicians' decisions for its further use. Recommendations are also made for improving the reporting of data from future RCTs using the DLQI.

Disease burden and treatment satisfaction in patients with prurigo nodularis in Japan

Prurigo nodularis (PN) is a chronic inflammatory skin disorder with a high disease burden. In this cross-sectional, web-based survey, Global Questions (GQ), the Numerical Rating Scales (NRS) for pruritus, burning sensation and sleep disturbance, the Short-Form-8 (SF-8) Health Survey, Dermatology Life Quality Index (DLQI), Patient Health Questionnaire 9 (PHQ-9), Work Productivity and Activity Impairment (WPAI), and Treatment Satisfaction Questionnaire for Medication-9 (TSQM-9) scores were used to assess the current disease burden and treatment satisfaction among patients with PN in Japan. In total, 97 patients were included (55.7% male, median age 51 years, median duration of PN 36 months). Based on GQ scores, 35.1% of patients had mild disease, 50.5% moderate, and 14.4% severe disease. Disease burden increased as the severity of PN increased, as indicated by worsening of pruritus NRS scores and quality of life (DLQI, PHQ-9, WPAI presenteeism, work productivity loss, and activity impairment scores). Patients with comorbid atopic dermatitis (AD) also had more intense pruritus than those without AD. Mean ± standard deviation TSQM-9 scores for effectiveness, convenience, and global satisfaction were 54.7 ± 18.1%, 62.4 ± 15.2%, and 57.4 ± 15.9%, respectively. TSQM-9 scores were lowest in patients receiving the most intensive guideline-directed treatment (i.e., topical corticosteroids + systemic oral corticosteroids or cyclosporine), highlighting an unmet need for more effective treatment options for patients with PN. In summary, Japanese patients with PN reported increased disease burden and reduced treatment satisfaction with increased disease severity, despite the use of guideline-recommended therapies.

Patients' perspective, quality of life and treatment goals in Hailey-Hailey disease: Lessons learned from the German National Registry

BACKGROUND

Hailey-Hailey disease (HHD) remains a difficult-to-treat dermatosis and little is known about the patient's perception of the disease activity, the treatment success and its impact on quality-of-life (QoL).

OBJECTIVE

To obtain better understanding of HHD patients' needs regarding their medical condition, financial burden, QoL, subjective well-being and treatment thereof as well as satisfaction to evaluate common treatments' 'real-life' relevance.

METHODS

With initiation of the national registry for Darier's disease (DD; Morbus Darier, MD) and Hailey-Hailey disease (HH) MDHHgermany, patients with HHD diagnosis were included starting June 2020. To assess subjective symptoms, patients filled out questionnaires such as the DLQI (dermatological life quality index), numeric rating scale (NRS) for itch, pain and burning sensation, as well as the SWLS (satisfaction with life scale) questionnaire to quantify overall satisfaction in life. Additionally, data on therapies were collected along with the patients' satisfaction of those and their medical care. Furthermore, patients assessed financial aspects and work ability.

RESULTS

One hundred and two patients were recruited from dermatology clinics, office-based dermatologists and self-help platforms across Germany between June 2020 and February 2023, 90 were eligible and analysed (mean: 49.91 years, 73.33% females, 26.67% males). 39.77% stated according to the DLQI their life is severely/very severely affected. Satisfaction with life was mediocre. Burning sensation was most pronounced among subjective symptoms (NRS 5.85 ± 2.80). Systemic treatments were rated as ineffective according to 56.92%, 25.56% had never received one. Most prescribed systemic treatments were corticosteroids (73.8%), followed by low-dose naltrexone (LDN) (26.2%), retinoids (15.4%) and antibiotics (13.8%). Satisfaction with medical care was generally low.

CONCLUSION

Our 'real-life' data state a major disease burden and impact on the QoL for affected individuals, as well as limited disease control due to inadequate therapies. MDHHgermany can provide insights into improvement of healthcare support with this debilitating disease and improve QoL. In the long term, it aims to provide basis for further clinical trials, epidemiological studies and immunological investigations.

Assessment of Patient-Reported Outcomes at 48 Months of Treatment with Dupilumab for Severe Atopic Dermatitis: A Single-Center Real-Life Experience with 126 Patients

BACKGROUND

The main objective was to analyze patient-reported outcomes (PRO) trends over a four-year period in severe atopic dermatitis (AD) patients treated with dupilumab.

METHODS

data from 126 severe patients receiving dupilumab for at least 48 months were collected. The clinical scores assessed included the Eczema Area and Severity Index (EASI), Pruritus Numerical Rating Scale (NRS), Sleep NRS, Patient-Oriented Eczema Measure (POEM), Dermatology Life Quality Index (DLQI), and Atopic Dermatitis Control Tool (ADCT).

RESULTS

the study compellingly demonstrates dupilumab's effectiveness in reducing EASI and improving PROs, with sustained enhancements observed beyond the initial twelve months of treatment. Univariate and multivariate regression analyses show that baseline factors do not significantly increase the risk of adverse outcomes related to Pruritus NRS, POEM, or ADCT at T48. The robust correlation between ADCT and other PROs suggests closely aligned changes.

CONCLUSION

Dupilumab's benefits endure beyond the first year, emphasizing its long-term efficacy, and consistently improves AD outcomes regardless of individual characteristics or clinical variables. ADCT appears to be a practical and versatile tool for the streamlined assessment of AD treatment outcomes.

Hand Eczema in High School Students in Poland: A Cross-sectional Study

Abstract is missing (Short communication)

Burden of Hidradenitis Suppurativa: A Systematic Literature Review of Patient Reported Outcomes

INTRODUCTION

Hidradenitis suppurativa (HS) has a profound negative impact on patients' health-related quality of life (HRQoL). Here we summarize the evidence on HRQoL and Patient Reported Outcomes (PROs) in patients with HS in real-world settings by conducting a systematic literature review (SLR) of observational studies.

METHODS

Data sources included MEDLINE, Embase & PsycINFO between January 1, 2010 and August 29, 2021, and conference proceedings between 2019 and 2021. Identified abstracts were reviewed and screened independently by two reviewers. Eligibility criteria included patients with HS of any severity, sample size ≥ 100, reporting PROs including HRQoL measures. Included studies were critically appraised.

RESULTS

Fifty-eight observational studies matched inclusion criteria. Dermatology Life Quality Index (DLQI) was the most commonly utilized instrument: 57% of included studies reported mean baseline DLQI scores, ranging between 8.4 and 16.9, indicating a very large impact on the patients' HRQoL. Higher scores were reported with increasing disease severity and among female patients. Pain was assessed mostly by an 11-point (0-10) numeric rating scale (NRS) with a mean baseline score ranging from 3.6 to 7.7 indicating moderate to high pain levels. There was a negative impact of HS on patients' psychological well-being, based on PRO scores related to depression and anxiety. A high proportion of sexual dysfunction was reported, with a larger impact on women than men. Work productivity and leisure activity were consistently found to be impaired in patients with HS.

CONCLUSIONS

All included studies reported a negative impact of HS on patients' lives. A diverse set of disease- and non-disease-specific PRO instruments were utilized highlighting the need for more consistent use of HS-specific validated PRO instruments to assess the impact of HS on the different aspects of patients' HRQoL to allow for data to be more meaningfully interpreted and compared in real-world settings. Patients with HS need better disease management approaches that address the observed low quality of life.

Neck scar perception after neck dissection in HPV-associated oropharyngeal squamous cell carcinoma

IMPORTANCE

While there has been an increased understanding of the impact of visible neck scars in some patients with certain diseases, this has not yet been explored in the HPV+ OPSCC population.

OBJECTIVE

To understand patients' perception of their scar and the impact on their quality of life (QOL) at least 6 months after neck dissection (ND) for HPV+ oropharyngeal squamous cell carcinoma (OPSCC).

DESIGN, SETTING, AND PARTICIPANTS

In this retrospective case-control study, patients who underwent primary transoral robotic surgery (TORS) and ND for HPV+ OPSCC between 2016 and 2021 at a single tertiary care center were identified. Data analysis was performed in January 2022.

MAIN OUTCOMES AND MEASURES

Dermatology Life Quality Index was modified (mDLQI) to assess patients' perceptions of their scars. The primary outcome was the mean mDLQI survey score with higher scores corresponding to worse perceptions. Three questions adapted from the Self-Consciousness Scale (SCS) were also included to assess awareness of appearance. All questions were scaled on a 0-3 Likert Scale. Tweedie generalized linear model was used to understand the relationship between mDLQI score and patient- and procedure-specific factors (including the three SCS survey questions). An additional exploratory logistic regression was performed to understand the risk factors for clinically significant mDLQI score change.

RESULTS

A total of 67 patients (response rate 57 %) completed the survey with a mean mDLQI survey score of 0.84 (max 30). Although there was a statistically significant negative association between private insurance and mDLQI survey score (95 % Confidence Interval [CI]: -2.72 - -0.38), and a positive association between the SCS score and mDLQI survey score (95 % CI: 0.23-0.81) (p < 0.05), these variables were not found to be risk factors for a clinically significant difference in mDLQI on multivariable analysis.

CONCLUSION

The majority of patients felt their neck scars did not interfere with their daily lives. Patient perceptions of neck scars were consistent despite differing patient characteristics and treatment regimens.

Females May Have Less Severe Acne, but They Suffer More: A Prospective Cross-Sectional Study on Psychosocial Consequences in 104 Consecutive Polish Acne Patients

Acne is a common skin condition affecting both adolescents and adults, and it can profoundly impact patients' quality of life and mental well-being. This prospective cross-sectional study aims to explore the differences in psychosocial aspects between male and female acne patients in Poland. A total of 104 consecutive acne patients were included in this study. Clinical severity, patients' quality of life, stigmatization levels, and psychiatric disturbances were evaluated using the following instruments: Investigator Global Assessment (IGA), Dermatology Life Quality Index (DLQI), Cardiff Acne Disability Index (CADI), 6-Item Stigmatization Scale (6-ISS), and Hospital Anxiety and Depression Scale (HADS). This study found that female patients exhibited significantly less severe acne and experienced significantly decreased quality of life and increased levels of stigmatization. Furthermore, anxiety levels among female patients exceeded those observed in their male counterparts. Notably, no disparities in the severity of depression were observed between the two gender groups. Correlations were discerned among all psychosocial parameters in the entire study cohort and in the female subgroup, while such correlations were not uniformly observed among male participants. This study underscores the importance of considering psychosocial aspects and implementing routine measurements in the management of acne to improve patients' well-being.

A prospective randomized controlled trial of Psychodermatology on the efficacy of Rilastil Difesa Sterile® cream in the hand eczema of healthcare workers during the COVID-19 pandemic

Hand eczema is one of the most frequent dermatological diseases, with an incidence increased during the COVID-19 pandemic. The impact on life quality is considerable, giving rise to the need for a psycho-dermatological approach. This is a Randomized Control Trial (RCT) evaluating, either by the dermatological or psychological point of view, the effectiveness of an emollient and rehydrating topical product (Rilastil Difesa Sterile® cream) versus a standard treatment (i.e. moisturizing basic cream) in a group of 51 healthcare workers suffering from hand eczema during the COVID-19 pandemic. The enrolled subjects were randomized into a treatment or a control arm, treated for 8 weeks, and monitored through a clinical score (HECSI) and questionnaires evaluating the impact of the pathology and treatment on quality of life (DLQI and QOLHEQ). A psychometric evaluation was performed using the SCL-90 R, OCI-R, and CPDI scales. Our data, despite not reaching the statistical significance, demonstrated that both the clinical and psychological scores decreased mostly in patients treated with Rilastil Difesa Sterile® cream when compared to those treated with simple topical emollients. Moreover, we observed a high level of psychic suffering in dermatological patients and a parallel change in dermatological and psychological indicators, thus confirming their connection.

Safety and Efficacy of Ixekizumab in Chinese Adults with Moderate-to-Severe Plaque Psoriasis: A Prospective, Multicenter, Observational Study

INTRODUCTION

Psoriasis, an incurable chronic inflammatory disease, affects over 6 million people in China. Ixekizumab, a monoclonal antibody against interleukin-17A, has demonstrated efficacy and safety for the treatment of moderate-to-severe plaque psoriasis, although limited data are available regarding its use in routine clinical practice in China. We investigated the real-world application of ixekizumab in China.

METHODS

Adults (≥ 18 years) with moderate-to-severe plaque psoriasis prescribed ixekizumab in routine clinical practice were enrolled in this prospective, observational, single-arm, multicenter, post-marketing surveillance study. The primary endpoint was the safety of ixekizumab at week 12. The effectiveness of ixekizumab, based on the Psoriasis Area and Severity Index (PASI) and Dermatology Life Quality Index (DLQI), was assessed as a secondary endpoint.

RESULTS

In total, 666 patients were enrolled; 663 were included in the safety analysis, and 612 in the effectiveness analysis. At least one adverse event (AE) was reported by 42.7% (283/663) of patients, most of which were mild (242/283, 85.5%), and 32.7% (217/663) of patients reported AEs related to study treatment. The most frequently reported AEs were injection site reactions. AEs led to discontinuation in five patients (0.8%). Only three patients had a serious AE. Mean ± standard deviation (SD) change from baseline in PASI score was reduction in 10.79 ± 9.55 at week 2 and 16.80 ± 12.15 at week 12. At week 2, 63.7% of patients achieved PASI 50. At week 12, 93.2%, 77.4%, and 45.1% of patients achieved PASI 75, PASI 90, and PASI 100, respectively. Mean ± SD change from baseline in DLQI was reduction in 5.91 ± 6.27 at week 2 and 9.76 ± 7.16 at week 12. DLQI 0/1 was achieved by 19.8% and 59.9% of patients at week 2 and 12, respectively.

CONCLUSION

Ixekizumab was well tolerated and effective in real-world clinical practice in Chinese adults with moderate-to-severe plaque psoriasis.

The Effect of Melasma on the Quality of Life in People with Darker Skin Types Living in Durban, South Africa

Melasma is a common skin disorder of acquired hyperpigmentation that appears commonly on the face. Although asymptomatic, melasma causes psychosocial and emotional distress. This study aimed to assess melasma's severity on people with darker skin types, evaluate the effects of melasma on the quality of life (QoL), and establish QoL predictors in affected individuals. This was a cross-sectional analytic study that enrolled 150 patients from three private dermatology clinics in Durban, South Africa who were diagnosed with melasma. The severity of melasma alongside QoL were measured using a melasma area and severity index (MASI) score and melasma quality of life scale (MELASQoL), respectively. The associations among factors and QoL were explored using multivariable methods and stepwise regression analysis. p-values less than 0.05 were considered significant. Enrolled patients were predominantly females (95%), of which 76% were of black African ethnicity, 9% were of Indian ethnicity, and 15% had mixed ancestry, with an average age of 47.30 years. Family history revealed that 61% had no prior melasma cases, while 39% had affected relatives, most commonly mothers (41%). The cheeks were the most common site for melasma. MASI score of Masi (β = 0.209, t = 2.628, p < 0.001), the involvement of cheeks (β = -0.268, t = -3.405, p < 0.001), level of education (β = -0.159, t = -2.029, p = 0.044), and being menopausal (β = -0.161, t = -2.027, p = 0.045) were found to be predictors of QoL. A regression model was created to forecast MELASQoL using these four predictors. This equation's significance lies in its ability to enable the remote assessment of MELASQoL based on these four variables. It offers a valuable tool for researchers and medical professionals to quantitatively and objectively evaluate the impact of melasma on an individual's quality of life.

Tapinarof cream 1% once daily for the treatment of plaque psoriasis: Patient-reported outcomes from the PSOARING 3 trial

BACKGROUND

Tapinarof cream 1% once daily demonstrated significant efficacy versus vehicle and was well tolerated in two 12-week, phase 3 pivotal trials in adults with mild-to-severe plaque psoriasis.

OBJECTIVE

To assess long-term, health-related quality of life and patient satisfaction with tapinarof.

METHODS

Patients completing the 12-week trials were eligible for 40 weeks of open-label tapinarof based on Physician Global Assessment score in PSOARING 3, with a 4-week follow-up. Dermatology Life Quality Index was assessed at every visit; Patient Satisfaction Questionnaire responses were assessed at week 40 or early termination.

RESULTS

Seven hundred sixty-three (91.6%) eligible patients enrolled; 78.5% completed the Patient Satisfaction Questionnaire. DLQI scores improved and were maintained. By week 40, 68.0% of patients had a DLQI of 0 or 1, indicating no impact of psoriasis on health-related quality of life. Most patients strongly agreed or agreed with all Patient Satisfaction Questionnaire questions assessing confidence in tapinarof and satisfaction with efficacy (62.9%-85.8%), application ease and cosmetic elegance (79.9%-96.3%), and preference for tapinarof versus prior psoriasis therapies (55.3%-81.7%).

LIMITATIONS

Open-label; no control; may not be generalizable to all forms of psoriasis.

CONCLUSIONS

Continued and durable improvements in health-related quality of life, high rates of patient satisfaction, and positive perceptions of tapinarof cream were demonstrated.

Comparison of risankizumab and apremilast for the treatment of adults with moderate plaque psoriasis eligible for systemic therapy: results from a randomized, open-label, assessor-blinded phase IV study (IMMpulse)

BACKGROUND

Treatment of psoriasis with risankizumab has demonstrated superior efficacy to other treatments, such as adalimumab, ustekinumab and secukinumab.

OBJECTIVES

This study compared the efficacy and safety of risankizumab and apremilast in adults with moderate plaque psoriasis eligible for systemic therapy. It also evaluated the efficacy and safety of switching to risankizumab vs. continuing apremilast in patients who did not achieve ≥ 75% improvement in Psoriasis Area and Severity Index (PASI 75 nonresponders) after 16 weeks of treatment with apremilast.

METHODS

This 52-week, phase IV, multicentre, randomized, open-label, efficacy assessor-blinded study (NCT04908475) enrolled patients (aged ≥ 18 years) with a diagnosis of moderate chronic plaque psoriasis (≥ 6 months) and who were candidates for systemic therapy. The enrolled patients (randomized 1 : 2) received subcutaneous risankizumab (150 mg at weeks 0 and 4) or oral apremilast (30 mg twice daily). At week 16, all patients treated with apremilast were re-randomized (1 : 1) to risankizumab or apremilast, stratified by week-16 PASI 75 response. The co-primary outcomes in period A at week 16 were the achievement of ≥ 90% improvement in Psoriasis Area and Severity Index (PASI 90) and static Physician's Global Assessment (sPGA) 0/1 with a two-grade or better improvement from baseline. At week 52, the primary endpoint in period B was the achievement of PASI 90 in PASI 75 nonresponders with apremilast at week 16. Safety was monitored throughout the study. All patients who received one dose of treatment were included in the efficacy and safety analysis.

RESULTS

At baseline, 118 and 234 patients were assigned to receive risankizumab and apremilast, respectively. At week 16, PASI 90 was achieved by 55.9% [95% confidence interval (CI) 47.0-64.9] and 5.1% (95% CI 2.3-8.0), and sPGA 0/1 by 75.4% (95% CI 67.7-83.2) and 18.4% (95% CI 13.4-23.3), respectively. In period B, among PASI 75 nonresponders with apremilast at week 16, 83 switched to risankizumab and 78 continued apremilast. At week 52, 72.3% (95% CI 62.7-81.9) who switched to risankizumab achieved PASI 90 vs. 2.6% (95% CI 0.0-6.1) who continued apremilast. The most frequent adverse events (reported in ≥ 5%) in risankizumab-treated patients were COVID-19 infection and nasopharyngitis. Diarrhoea, nausea and headache were most frequent among apremilast-treated patients.

CONCLUSIONS

For patients with moderate psoriasis, treatment with risankizumab demonstrated superior efficacy to those treated with apremilast, including those who did not benefit from prior treatment with apremilast. The safety profile of risankizumab was similar to prior studies, and no new safety signals were identified. These results show that, compared with apremilast, risankizumab treatment can significantly improve clinical outcomes in systemic-eligible patients with moderate psoriasis.

Psychometric evaluation of the Worst Pruritus Numerical Rating Scale (NRS), Atopic Dermatitis Symptom Scale (ADerm-SS), and Atopic Dermatitis Impact Scale (ADerm-IS)

BACKGROUND

Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by pruritus, skin pain, and sleep impacts, which are only reportable by patients themselves. The goal of this research is to evaluate the reliability, validity, and interpretability of the scores from three patient-reported outcome measures within the context of a clinical trial for adolescents and adults with moderate to severe AD.

METHODS

Data from a Phase 3 randomized, double-blind, placebo-controlled, multinational clinical trial for individuals 12-75 years of age with moderate to severe AD (AD Up [ClinicalTrials.gov NCT03568318]) were used to assess the reliability, validity, and interpretability of scores on the Worst Pruritus Numerical Rating Scale (NRS) and the Atopic Dermatitis Symptom and Impact Scales (ADerm-SS and ADerm-IS). Analyses were conducted separately for the adult and adolescent subgroups.

RESULTS

Of the 882 participants included in the psychometric analyses, the majority were adults (n = 769, 87.2%), male (n = 536, 60.8%), and white (n = 630, 71.4%). Multi-item scores from the ADerm-SS and ADerm-IS had good internal consistency reliability, and most scores demonstrated acceptable test-retest reliability. Scores from the three questionnaires demonstrated adequate validity, exhibiting correlations with other conceptually related outcome assessments and score differences between clinically distinct subgroups. Finally, the score interpretation analyses provide estimates for meaningful within-person change and between-groups difference thresholds that may be useful for future research in adults and adolescents with moderate to severe AD.

CONCLUSIONS

These results provide evidence that the scores produced by the Worst Pruritus NRS, ADerm-SS, and ADerm-IS are reliable and construct-valid when completed by adults and adolescents with moderate to severe AD in a clinical trial setting. The results presented here expand upon the previous qualitative evidence of these tools and provide further support for their use in future clinical studies. While results are specific to clinical trials, next steps would be to evaluate the use of these questionnaires in clinical practice. This can provide clinicians and dermatologists a window into the patient's disease experience outside of the clinic, aid in shared decision making, and support a patient-centric approach to management of moderate to severe AD.

Calcipotriene and Betamethasone Dipropionate PAD-Cream Demonstrates Greater Treatment Efficacy in Patients with Moderate-to-Severe Psoriasis Compared to Topical Suspension/Gel: A Subgroup Analysis of Two Phase 3 Studies

INTRODUCTION

Psoriasis ranges from mild to severe with the majority of patients having mild disease. Mild to moderate disease is often treated with topical therapies while photo-, oral, and biologic therapies are generally reserved for moderate-to-severe disease. There is a strong scientific rationale for the combination of calcipotriene (CAL) and betamethasone dipropionate (BDP) with respect to mode of action, efficacy, and safety and CAL/BDP has shown an inhibitory effect on key pathogenic cytokines in psoriasis including tumor necrosis factor-α, interleukin (IL)-17, and IL-23.

METHODS

The objective of this pooled post hoc analysis is to investigate the efficacy of CAL/BDP polyaphron dispersion (PAD)-cream in subgroups of patients with moderate-to-severe psoriasis from two completed phase 3 studies conducted in the USA and Europe.

RESULTS

The proportion of patients achieving Physician Global Assessment (PGA) treatment success as well as a modified Psoriasis Area and Severity Index (mPASI)75 response was higher in the subgroup with a body surface area > 10% and mPASI > 10 and Dermatology Life Quality Index > 10 at baseline compared to the overall patient population. Furthermore, the numerical difference in treatment efficacy between CAL/BDP PAD-cream and CAL/BDP topical suspension/gel increased in patient subgroups with higher baseline severity. Similar patterns were shown for the patient-reported outcomes.

CONCLUSION

In this subgroup analysis, patients who had higher disease severity at baseline achieved greater efficacy than the total patient population when treated with 8 weeks of CAL/BDP PAD-cream as compared to a currently marketed active comparator. Additionally, as indicated by this analysis, CAL/BDP PAD-cream treatment may also be more convenient and less greasy, which may reduce the burden of daily treatment and improve adherence to therapy.

Bimekizumab efficacy and safety in patients with moderate to severe plaque psoriasis: Two-year interim results from the open-label extension of the randomized BE RADIANT phase 3b trial

BACKGROUND

Bimekizumab is a monoclonal IgG1 antibody that inhibits interleukin-17A/F. Bimekizumab is more efficacious than secukinumab over 1 year in the treatment of psoriasis.

OBJECTIVE

Evaluate the safety and efficacy of bimekizumab through 2 years in patients with moderate to severe plaque psoriasis.

METHODS

The BE RADIANT phase 3b randomized controlled trial consisted of a 48-week double-blinded period, where patients received bimekizumab (320 mg every 4 or 8 weeks) or secukinumab (300 mg weekly to Week 4, then every 4 weeks), and an open-label extension (OLE). From Week 48, all patients received bimekizumab in the OLE.

RESULTS

At Week 48, more patients achieved complete skin clearance (PASI 100; modified non-responder imputation) with bimekizumab than secukinumab (74.8% vs 52.8%). PASI 100 responses were maintained to Week 96 in continuous bimekizumab patients (70.8%); patients who switched from secukinumab to bimekizumab had increased rates at Week 96 (76.6%). The most common adverse events were: nasopharyngitis, oral candidiasis, and urinary tract infection. Safety data were consistent with the known safety profile of bimekizumab.

LIMITATIONS

Limited racial diversity; overlap with the COVID-19 pandemic.

CONCLUSIONS

High PASI 100 responses achieved with bimekizumab over 48 weeks were sustained through Week 96; secukinumab patients who switched to bimekizumab achieved similar responses by Week 96.

Prevalence and burden of atopic dermatitis involving the head, neck, face, and hand: A cross sectional study from the TARGET-DERM AD cohort

BACKGROUND

Atopic dermatitis (AD) is severely burdensome, and there has been poor characterization of any differences in impact based on the area affected.

OBJECTIVE

To estimate the prevalence and HRQoL impact of head/face/neck/hand (HFNH) involvement among patients with moderate-to-severe atopic dermatitis.

METHODS

All TARGET-DERM AD registry patients with moderate/severe Investigator Global Assessment (vIGA-AD) were assessed using the Patient Oriented SCORing Atopic Dermatitis, Patient Oriented Eczema Measure (POEM) and the (Children's) Dermatology Life Quality Index ((C)DLQI).

RESULTS

541 participants met the criteria (75.0% adults) and 84% (N = 453) reported HFNH involvement. HFNH and non-HFNH involved participants had similar characteristics; 55.2% female and 46.9% White. Compared to the non-HFNH involved, the involved had severe vIGA-AD (28.5% vs 16.3%, P = .02) and higher median body surface area affected (15% vs 10%, P ≤ .01) and were twice as likely to have higher (C)DLQI and POEM scores.

LIMITATIONS

This was an analysis of real-world and patient reported outcome data.

CONCLUSION

Real-world HFNH involved AD patients were associated with significantly worse quality of life, POEM/(C)DLQI, and more severe disease. Detailed assessments of specific areas affected by AD are needed to personalize treatment.

Most Patients With Autoimmune Chronic Spontaneous Urticaria Also Have Autoallergic Urticaria, but Not ViceVersa

BACKGROUND

Two endotypes of chronic spontaneous urticaria (CSU) associated with mast cell-activating autoantibodies are described, namely autoallergic chronic spontaneous urticaria (aaCSU; with immunoglobulin E [IgE]-anti-autoallergens) and autoimmune chronic spontaneous urticaria (aiCSU; with IgG-anti-high-affinity receptor for the Fc region of immunoglobulin E [FcεRI]/IgE).

OBJECTIVE

To investigate the rates of CSU patients with aaCSU and aiCSU.

METHODS

We analyzed 111 CSU patients for aaCSU (ie, IgE to thyroid peroxidase, interleukin 24) and for aiCSU (ie, a positive autologous serum skin and Basophil Activation Test plus immunoglobulin G [IgG]-anti-FcεRI/IgE). Clinical and laboratory parameters were compared in patients with aaCSU, aiCSU, and both.

RESULTS

Across 111 patients with CSU, 64 (58%) had aaCSU and 9 (8%) had aiCSU. Eight of the 9 aiCSU patients had aaCSU, but only 8 of 64 patients with aaCSU had aiCSU. In total, 7% (8 of 111) of patients had both aiCSU and aaCSU, 41% (46 of 111) had neither, and 16% (18 of 111) tested negative for all markers of aaCSU and aiCSU assessed. Patients with aaCSU or aiCSU are different from those without: patients with stand-alone aaCSU tend to be younger than non-aaCSU patients, aiCSU, and aaCSU/aiCSU overlapping subpopulations. In contrast, patients with aiCSU, with or without aaCSU coexistence, are more often female, have higher levels of thyroid peroxidase autoantibodies (both IgG and IgE), and show more severe quality of life impairment.

CONCLUSIONS

Our novel finding that aiCSU coexisting with aaCSU needs to be confirmed in bigger cohorts and multicenter studies. Autoimmunity driven by autoreactive IgE and/or IgG in CSU needs further investigation for better understanding of the pathophysiology.

The Psychological Impact of Vitiligo in Saudi Arabia

Background Vitiligo, the most common pigment disorder, impacts 0.5-2% of the global population, often causing psychological distress due to appearance changes and potential discrimination. Existing data on depressive symptoms and quality of life (QoL) effects in Saudi Arabian vitiligo patients are limited and inconsistent. Hence, this multi-center investigation was conducted in Saudi Arabia to determine the prevalence of depressive symptoms and quality of life (QoL) impairment in patients with vitiligo and to identify factors linked to increased psychological distress in this population. Methods We conducted a multi-center cross-sectional study in Saudi Arabia, employing two validated Arabic questionnaires, the Dermatology Life Quality Index (DLQI) and the Patient Health Questionnaire-9 items (PHQ-9), along with demographic information. Appropriate statistical analyses were performed. Results In total, 204 patients completed the survey. The median DLQI was 4 (range: 25), while the median PHQ-9 was 5 (range: 27). Factors associated with worse QoL included an early age of onset (under 18 years) and a disease duration exceeding five years. Conversely, only disease duration correlated with worse PHQ-9 scores. Vitiligo lesions on the lower extremities, feet, and genitalia were linked to poorer DLQI scores, while only genitalia were associated with worse PHQ-9 scores. We recommend further social awareness campaigns emphasizing the role of supportive families to improve the well-being of vitiligo patients.

Chronic Spontaneous Urticaria: How to Measure It and the Need to Define Treatment Success

Chronic spontaneous urticaria (CSU) is a complex skin disease characterized by the spontaneous appearance of wheals, angioedema, or both, for more than 6 weeks. Many patients experience a relapsing-remitting disease course for years. Owing to the unpredictability of wheal recurrence and the severity of pruritis, patients suffer considerable impairment in their quality of life. Physicians face multiple challenges, not least of which is a lack of clear guidance on what constitutes "treatment success". There is a lack of awareness of which measures should be used to best assess the various aspects of CSU, including disease activity, disease control, and quality of life-which themselves each comprise multiple components-and how to apply the results of each score to treatment decision-making. Although the overarching aim of treatment is for patients to be completely free of signs and symptoms of CSU, a more realistic definition of "treatment success" is needed to guide ongoing, long-term disease management for each individual patient. In this review, we consider what lessons can be learned from the current evidence base to provide further direction toward a universal definition of "treatment success".

Why a Complete Response Is the Treatment Aim in Chronic Spontaneous Urticaria

This study investigated the association between urticaria activity and health-related quality of life (HRQoL). Patient evaluations from the ligelizumab Phase 2b clinical trial (N = 382) were pooled (NCT02477332). Daily patient diaries assessed urticaria activity, sleep and activity interference, the dermatology life quality index (DLQI), and work productivity and activity impairment-chronic urticaria (WPAI-CU). The number of DLQI scores, weekly sleep interference scores (SIS7), weekly activity interference scores (AIS7), and overall work impairment (OWI) evaluations with a complete response per weekly urticaria activity score (UAS7) using bands (0, 1-6, 7-15, 16-27, and 28-42) were reported. Over 50% of the patients had a mean DLQI of > 10 at baseline, indicating a significant effect of chronic spontaneous urticaria (CSU) on their HRQoL. Complete response (UAS7 = 0) evaluations corresponded with no impacts on other patient-reported outcomes. In total, 91.1% of UAS7 = 0 evaluations corresponded to DLQI scores of 0-1, 99.7% to SIS7 scores of 0, 99.7% to AIS7 scores of 0, and 85.3% to OWI scores of 0. This was significantly different compared with the UAS7 = 1-6 evaluations (61.9%, 68.5%, 67.7%, and 65.4%, respectively; p < 0.0001). Complete responses to treatment were associated with no impairments on the dermatology-QoL, no interferences with sleep and activity, and significantly improved capacities to work compared to patients who continued to have signs and symptoms, even for those with minimal disease activity.

Validation and usability of modified palmoplantar psoriasis area and severity index in patients with palmoplantar psoriasis: A prospective longitudinal cohort study

Background Palmoplantar psoriasis (PPP), a troublesome variant, does not have any validated scoring system to assess disease severity. Objective To validate modified Palmoplantar Psoriasis Area and Severity Index (m-PPPASI) in patients affected with PPP and to categorise it based on Dermatology Life Quality Index (DLQI). Methods In this prospective study, patients with PPP aged > 18 years visiting the psoriasis clinic at a tertiary care centre were included and requested to complete DLQI during each visit at baseline, 2nd week, 6th and 12th week. m-PPPASI was used by the raters to determine the disease severity. Results Overall, 73 patients were included. m-PPPASI demonstrated high internal consistency (α = 0.99), test-retest reliability of all three raters, that is, Adithya Nagendran (AN) (r = 0.99, p < 0.0001), Tarun Narang (TN) (r = 1.0, p < 0.0001) and Sunil Dogra (SD) (r = 1.0, p < 0.0001) and inter-rater agreement (intra-class correlation coefficient = 0.83). Face and content validity index for items I-CVI = 0.845 were robust, and the instrument was uniformly rated as easy to use (Likert scale 2) by all three raters. It was found to be responsive to change (r = 0.92, p < 0.0001). Minimal clinically important differences (MCID)-1 and MCID-2 calculated by receiver operating characteristic curve using DLQI as anchor were 2 and 35%, respectively. DLQI equivalent cutoff points for m-PPPASI were 0-5 for mild, 6-9 for moderate, 10-19 for severe, and 20-72 for very severe disease. Limitation Small sample size and single-center validation were the major limitations. m-PPPASI doesn't objectively measure all characteristics of PPP such as "fissuring" and "scaling" which could also be taken into consideration. Conclusion m-PPPASI is validated in PPP and can be readily utilized by physicians. However, further large-scale studies are needed.
