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.

Development of the acne-specific quality of life questionnaire Quality of Life Relevance-Acne.

Background: Participating members of the European Academy of Dermatology and Venereology Task Forces on quality of life (QoL) and Patient Oriented Outcomes and Acne, Rosacea and Hidradenitis Suppurativa initiated data collection in 9 European countries and formed the list of the most relevant topics for acne patients. Objective: The aim of this study was to develop a new acne-specific health-related QoL instrument based on the list of the most relevant topics for acne patients. Methods: After assessment by acne patients (n = 715) on how clear and relevant the items in the prototype questionnaire were, a group of experts on acne and QoL performed discussions on items inclusion, which resulted in a series of 21 items. Then another group of acne patients (n = 1502) filled in the new version of the instrument. A factor analysis was conducted on the 21-item version. Results: Three-factor model with 19 items indicated a satisfactory fit. The three dimensions were called: Socioemotional; Symptoms; Stigma and Suicidal thoughts. Limitations: Included patients and experts may not fully represent acne patients and health care professionals worldwide. Conclusion: A final 19-item version of the Quality of Life Relevance-Acne was developed.

Effectiveness, Tolerability, and Drug Survival of Risankizumab in a Real-World Setting: A Three-Year Retrospective Multicenter Study-IL PSO (ITALIAN LANDSCAPE PSORIASIS).

BACKGROUND: Risankizumab is a humanized monoclonal antibody that selectively inhibits interleukin-23. It has been approved for moderate-to-severe plaque psoriasis and has shown efficacy and safety in clinical trials and real-world experiences. This study aimed to evaluate the long-term effectiveness, safety, and drug survival of risankizumab in a real-life setting. MATERIALS AND METHODS: We included patients treated with risankizumab from January 2019 to February 2023. A Psoriasis Area and Severity Index score (PASI) was collected at weeks 0, 16, 28, 52, 104, and 156, when available. The occurrence of any adverse events was recorded at each visit. RESULTS: We enrolled 1047 patients. At week 52, a ≥90% improvement in PASI was observed in 81.44% of patients, with a continuous improvement throughout the study (88.99% and 99.07% at weeks 104 and 156, respectively). After three years of treatment, all patients involving the scalp, palms/soles, and genitalia and 95% of patients with nail psoriasis achieved a complete or almost complete skin clearance. No significant safety findings were observed, and 90.73% of the patients were still on treatment after 36 months. CONCLUSIONS: This study supports the long-term effectiveness and safety of risankizumab in a real-world setting, even in patients involving difficult-to-treat areas.

White paper on psychodermatology in Europe: A position paper from the EADV Psychodermatology Task Force and the European Society for Dermatology and Psychiatry (ESDaP).

Psychodermatology is a subspecialty of dermatology that is of increasing interest to dermatologists and patients. The case for the provision of at least regional psychodermatology services across Europe is robust. Psychodermatology services have been shown to have better, quicker and more cost-efficient clinical outcomes for patients with psychodermatological conditions. Despite this, psychodermatology services are not uniformly available across Europe. In fact many countries have yet to establish dedicated psychodermatology services. In other countries psychodermatology services are in development. Even in countries where psychodermatolgy units have been established, the services are not available across the whole country. This is especially true for the provision of paediatric psychodermatology services. Also whilst most states across Europe are keen to develop psychodermatology services, the rate at which this development is being implemented is very slow. Our paper maps the current provision of psychodermatology services across Europe and indicates that there is still very much more work to be done in order to develop the comprehensive psychodermatology services across Europe, which are so crucial for our patients.

Incidence of keratinocyte carcinomas in Italy: an exercise in indirect estimation based on melanoma data.

BACKGROUND: The occurrence of keratinocyte carcinomas (KC) worldwide appears to be increasing, however, information on the actual incidence of these tumours is often incomplete. OBJECTIVES: The aim of this study was to provide information on the KC/melanoma ratio in order to indirectly estimate the occurrence of KC. MATERIALS & METHODS: Data were collected according to a snowball sampling procedure between Italian dermatologists. Colleagues working on melanoma and non-melanoma units were excluded. These ratios were applied to estimates derived from histopathological records, namely melanoma incidence estimates available from the Italian National Cancer Registry Network. The final estimates for KC incidence were thus obtained using the formula: KC incidence (per 100,000) = melanoma incidence (per 100,000) * (KC/melanoma ratio). RESULTS: Our results revealed a BCC/melanoma ratio of 4.4 and SCC/melanoma ratio of 1.7; values that are approximately 4 to 5 times smaller than those self-reported by dermatologists. Interestingly, this large discrepancy was not observed for the BCC/SCC ratio, which was 2.5 in the north, 2.7 in the centre, and 3.2 in the south of Italy, with an overall value of 2.8. Based on the histopathological data, this ratio was 2.6. CONCLUSION: In Italy, the actual occurrence of BCC and SCC seems to be vastly underestimated based on histopathological data, compared to data reported by dermatologists.

Emotions at diagnosis in patients with bullous diseases.

BACKGROUND: Diagnosis of a severe condition may have a strong emotional impact on patients. Specific emotions experienced when receiving the diagnosis of a bullous disease have not been investigated. METHODS: Adult patients diagnosed with a bullous condition were recruited through the Italian Association of patients with pemphigus and pemphigoid (ANPPI). Information was collected online on sociodemographic and clinical data. We asked which emotions the patient experienced at the time of the diagnosis, i.e., isolation, anger, confusion, sadness, despair, disregard, fear, avoidance, and challenge. Also, the patients reported to whom they talked as soon as they had the diagnosis. RESULTS: Data were collected on 105 patients, most of whom were affected by pemphigus vulgaris. The emotion most frequently experienced at diagnosis was confusion (47.6% of patients). More than 30% of patients reported sadness and fear, 12.5% anger, and 10.5% despair. A significantly higher percentage of women than men experienced isolation and despair. Despair was more frequent in patients who were older at diagnosis. Patients with children experienced more sadness and despair, and less avoidance and challenge, while those who had a relative with a bullous disease reported less fear, and more challenge. CONCLUSIONS: Clinicians should be aware of the emotions of the patient when communicating the diagnosis of severe conditions, such as bullous diseases. Active listening and empathy are necessary to provide patients with correct information on the disease, so that they are not overwhelmed with negative emotions.

Brodalumab for the treatment of plaque psoriasis in a real-life setting: a 3 years multicenter retrospective study-IL PSO (Italian landscape psoriasis).

Introduction: Brodalumab is a monoclonal antibody that targets the subunit A of the interleukin-17A receptor (IL17RA), inhibiting the signaling of various isoforms of the IL-17 family. It has been approved for the treatment of moderate-to-severe plaque psoriasis after being evaluated in three Phase-3 trials. However, long-term data on brodalumab in a real-life setting are still limited. Methods: The aim of this study was to evaluate the long-term effectiveness and safety of brodalumab in psoriasis. We also assessed the drug survival of brodalumab in a 3 years timespan. We conducted a retrospective multicenter study on 606 patients followed up at 14 Italian dermatology units, all treated with brodalumab according to Italian guidelines. Patients' demographics and disease characteristics were retrieved from electronic databases. At baseline and weeks 12, 24, 52, 104 and 156, we evaluated the psoriasis area and severity index (PASI) score and investigated for adverse events. The proportions of patients reaching 75, 90 and 100% (PASI 75, PASI 90 and PASI 100, respectively) improvement in PASI, compared with baseline, were also recorded. Results: At week 12, 63.53% of the patients reached PASI 90 and 49.17% PASI 100. After 3 years of treatment, 65.22% of patients maintained a complete skin clearance, and 91.30% had an absolute PASI of 2 or less. Patients naïve to biological therapies had better clinical responses at weeks 12, 24 and 52. However, after 2 years of treatment, no significant differences were observed. Body mass index did not interfere with the effectiveness of brodalumab throughout the study. No new safety findings were recorded. After 36 months, 85.64% of our patients were still on treatment with brodalumab. Conclusion: Our data confirm the effectiveness and the safety of brodalumab in the largest real-life cohort to date, up to 156 weeks.

Perceived Stigmatization among Dermatological Outpatients Compared with Controls: An Observational Multicentre Study in 17 European Countries.

Perceived stigmatization places a large psychosocial burden on patients with some skin conditions. Little is known about the experience of stigmatization across a wide range of skin diseases. This observational cross-sectional study aimed to quantify perceived stigmatization and identify its predictors among patients with a broad spectrum of skin diseases across 17 European countries. Self-report questionnaires assessing perceived stigmatization and its potential predictors were completed by 5,487 dermatology outpatients and 2,808 skin-healthy controls. Dermatological diagnosis, severity, and comorbidity were clinician-assessed. Patients experienced higher levels of perceived stigmatization than controls (p < 0.001, d = 0.26); patients with psoriasis, atopic dermatitis, alopecia, and bullous disorders were particularly affected. Multivariate regression analyses showed that perceived stigmatization was related to sociodemographic (lower age, male sex, being single), general health-related (higher body mass index, lower overall health), disease-related (higher clinician-assessed disease severity, presence of itch, longer disease duration), and psychological (greater distress, presence of suicidal ideation, greater body dysmorphic concerns, lower appearance satisfaction) variables. To conclude, perceived stigmatization is common in patients with skin diseases. Factors have been identified that will help clinicians and policymakers to target vulnerable patient groups, offer adequate patient management, and to ultimately develop evidence-based interventions.

Real-life effectiveness of tildrakizumab in chronic plaque psoriasis: A 52-week multicentre retrospective study-IL PSO (Italian landscape psoriasis).

BACKGROUND: Tildrakizumab is a humanized monoclonal antibody that binds selectively the p19 subunit of interleukin-23. It is approved for treatment of moderate-severe chronic plaque psoriasis. OBJECTIVES: We conducted a 52-week retrospective study to assess the effectiveness and safety of tildrakizumab in a real-life setting. METHODS: Our retrospective study included 237 consecutive adults with moderate-to-severe plaque psoriasis, enrolled in 10 different Italian centres, treated with tildrakizumab up to Week 52. Patient characteristics, comorbidities, previous treatments and the PASI (Psoriasis Area and Severity Index) score at each visit (baseline, Week 16, Week 28 and Week 52) were retrieved from the electronic medical records. The percentages of patients achieving 75%, 90% and 100% (PASI 75, PASI 90 and PASI 100) improvement in PASI with respect to baseline PASI were registered. RESULTS: At Week 52, 90.91%, 73.55% and 58.68% of patients achieved a PASI reduction ≥75% (PASI 75), PASI 90 and PASI 100, respectively. An absolute PASI ≤ 2 was reached by 85.95% at Week 52. Compared with Phase 3 clinical trials, we observed similar rates of PASI 75/90 responses and higher percentages of patients achieving PASI 100. Patients who had not responded to previous biologic treatments and patients with cardio-metabolic comorbidities were significantly more likely to achieve PASI 100 at Week 28 and PASI 90 at Week 52. The higher body mass index did not interfere with the odds of reaching PASI 75/90/100 at each time point. No significant safety findings were recorded throughout the study, and none of the patients had to interrupt the treatment because of adverse events. CONCLUSION: Our data suggest that the efficacy of tildrakizumab for plaque psoriasis in 'real-life' clinical practice is comparable with Phase 3 clinical trials with higher percentages of patients achieving complete skin clearance (PASI 100) at Weeks 16, 28 and 52.

Quality of life measurement in vitiligo. Position statement of the European Academy of Dermatology and Venereology Task Force on Quality of Life and Patient Oriented Outcomes with external experts.

Members of the European Academy of Dermatology and Venereology (EADV) Task Force on Quality of Life (QoL) and Patient Oriented Outcomes reviewed the instruments available for health-related (HR) QoL assessment in vitiligo and together with external vitiligo experts (including representatives of the EADV Vitiligo Task Force) have made practical recommendations concerning the assessment of QoL in vitiligo patients. The Dermatology Life Quality Index (DLQI) was the most frequently used HRQoL instrument, making comparison of results between different countries possible. Several vitiligo-specific instruments were identified. The vitiligo Impact Scale (VIS) is an extensively validated vitiligo-specific HRQoL instrument with proposed minimal important change and clinical interpretation for VIS-22 scores. VIS-22 was developed for use in India, where there are some specific cultural beliefs concerning vitiligo. The EADV Task Force on QoL and Patient Oriented Outcomes recommends use of the DLQI and the Children's Dermatology Life Quality Index (CDLQI) as dermatology-specific instruments in vitiligo. There is a strong need for a valid (including cross-cultural validation) vitiligo-specific instrument that can be either a new instrument or the improvement of existing instruments. This validation must include the proof of responsiveness.

Which Health-Related Quality of Life Items Most Affect Acne Patients?

BACKGROUND: Health-related quality of life (HRQoL) assessment in patients with acne is recommended by several national guidelines. There are several acne-specific HRQoL instruments. OBJECTIVES: Participants of the European Academy of Dermatology and Venereology (EADV) Task Forces (TFs) on QoL and Patient Oriented Outcomes (PO) and Acne, Rosacea, and Hidradenitis Suppurativa (ARHS) agreed to scrutinize aspects of existing acne-specific HRQoL instruments for their relevance in international study. METHODS: Consensus agreement on items related to QoL was reached after an independent assessment by seven experts from the EADV TFs on QoL and PO, and a list of 97 items was prepared and proposed to a group of acne patients. In order to have data from patients to check if any important topics were overseen, another group of acne patients from participating countries was asked to list how acne influenced different aspects of their lives. RESULTS: Based on results obtained from 601 acne patients from nine countries, most of the items and topics showed low relevance for acne patients especially during the previous month or shorter time periods. Based on percentage of relevance and factor analysis, short (6 items) and long (45 items) lists of the most relevant topics were formed. CONCLUSION: Most of the items and topics from the initial list showed low relevance for acne patients. None of the identified acne-specific HRQoL instruments contain all the items that were deemed most relevant to acne patients. For this reason, participating members of the EADV TFs on QoL and PO, and ARHs are in the process of developing a new acne-specific HRQoL instrument.

Perceived stress in patients with inflammatory and non-inflammatory skin conditions. An observational controlled study among 255 Norwegian dermatological outpatients.

Background: Inflammation may increase stress, while stress may promote inflammation. Most dermatological conditions are chronic and inflammatory, while some, such as cancer, naevi and tumours are non-inflammatory, but may cause stress because of the fear of malignancy and the necessity for surgical and other invasive treatments. Stress among patients with skin diseases is little explored. Objectives: To assess perceived stress in patients with inflammatory and non-inflammatory skin conditions compared to healthy controls. Methods: Observational cross-sectional study. Consecutive outpatients (N = 255) visiting the Department of Dermatology, Stavanger University Hospital, Norway and 148 skin-healthy controls contributed by answering questionnaires on sociodemographics, stressful life events, economic difficulties, self-rated health and perceived stress. The validated Perceived Stress Scale10 was used to evaluate stress. A dermatologist examined patients and registered their diagnoses and comorbidities. Controls included in this study were not examined by a dermatologist and self-reported their comorbidities. Results: Patients with an inflammatory skin disease or psoriasis have a tripled risk of reporting moderate to high stress compared with controls when adjusted for relevant confounders, including having experienced a stressful life event recently or having a comorbidity. Patients with a purely non-inflammatory skin disease perceived stress no differently than controls. Conclusion: Patients with inflammatory skin disease perceived higher stress than controls and patients with non-inflammatory skin conditions. Dermatologists may play a role in awareness of the importance of stress in skin disease.

Testing some psychometric properties of the Italian version of the Skin Cancer Index: A questionnaire for measuring quality of life in patients with non-melanoma skin cancer.

Objectives: Non-melanoma skin cancers (NMSC) include two main types: basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC). Generic Health-Related Quality of Life (HRQoL) instruments revealed little to no HRQoL impairment in NMSC patients. Instead, the use of specific skin disease HRQoL tools contradicted those observations. For example, the Skin Cancer Index (SCI) was suggested as a validated instrument for the evaluation of the impact of skin cancers on HRQoL, and has already been validated in several languages, but not in Italian. The aim of this study is to testing some psychometric properties of the Italian version of the SCI questionnaire in a large sample of NMSC patients. Methods: This is a cross-sectional, single-center, observational study. Firstly, different factor models proposed in the literature were compared and the model with the best fit was identified. Secondly, the psychometric properties of the SCI, convergent validity and reliability, were evaluated. Results: The sample was composed of 371 NMSC patients. The factor analysis revealed that a revised version of the original model had the best fit [χ2(df = 85) = 354.53, p < 0.001, RMSEA = 0.09, CFI = 0.98, TLI = 0.97, SRMR = 0.03]. The SCI had satisfactory internal consistency for all subscales (Emotional subscale: ordinal alpha = 0.95; Social subscale: ordinal alpha = 0.94; Appearance subscale: ordinal alpha = 0.94). The convergent validity with Skindex-17 psychosocial subscale was adequate for all the SCI subscales (Emotional Subscale: rho = -0.50; Social Subscale: rho = -0.54; Appearance subscale: rho = -0.44; Total Skin Cancer Index: rho = -0.56; and p < 0.001). Conclusion: The tested psychometric properties of the Italian version of the SCI may suggest that it is an appropriate tool to measure the HRQoL in NMSC patients, however, further studies are needed in order to confirm and tested other psychometric features of this tool.
