Determining what represents value in the treatment of prurigo nodularis and its key unmet needs in Spain through Multi-Criteria Decision Analysis

Background: Prurigo nodularis (PN) is a chronic, debilitating dermatologic disease characterised by the presence of highly pruritic nodular lesions. PN highly impacts on patients' quality of life as there are no specific treatments available in Spain. Objectives: Determine the main value drivers in the treatment of PN in Spain and its main unmet needs using Multi‐Criteria Decision Analysis (MCDA). Methods: Literature review to synthesise relevant evidence in an evidence matrix based on the MCDA EVIDEM framework adapted to Spain. A multidisciplinary panel composed of dermatologists, hospital pharmacists and a patient weighted (5‐point scale; 0 minimum importance, 5 maximum importance) and scored each criterion included in the framework (from −5 to 5 or 0 to 5 depending on the criterion). Results were discussed in a reflective group session. Results: PN was considered a severe (3.3 ± 0.7) and infrequent (2.0 ± 0.7) disease, with high unmet needs (4.2 ± 0.7) mainly due to the lack of available treatments with specific indication for PN. Current off‐label treatments were perceived to have limited efficacy/effectiveness (1.8 ± 1.1), an unfavourable long‐term safety profile (2.1 ± 0.9) and low therapeutic impact (1.7 ± 1.1). The measure of patient‐reported outcomes (2.7 ± 0.9) was perceived as important, but available tools are not specific. Although the cost of available treatments was not considered high (2.4 ± 1.5), experts agreed that PN is associated with moderately high other medical costs (3.6 ± 1.1) and indirect costs (3.1 ± 0.9). Experts considered that current guidelines and consensus (2.6 ± 0.7) are not clear on severity criteria and treatment algorithm. The quality of evidence (1.4 ± 0.5) of currently used off‐label treatments was perceived as low due to a lack of published clinical trials.10 página

Assessing the value of moderate-to-severe atopic dermatitis treatment using multi-criteria decision analysis (MCDA)

Dear Editor, The increased understanding of atopic dermatitis (AD) pathophysiology has shed light on the underlying immuno- logical mechanisms and spurred the development of novel, more precisely targeted therapies.1 As new agents become available, assessing their added value is advisable. Yet the value of novel health interventions sometimes remains largely unmeasured and inadequately understood. 2 Value assessment is challenging since it involves assessing the ex- tent to which it meets current unmet needs. Therefore, it is necessary to establish the most relevant health outcomes from different stakeholders' perspectives. The main goal of AD treatment is to establish and sus- tain disease control, allowing patients to be fully functional in their lives. 3 Therefore, the value of novel treatments should be assessed not only according to their effectivity in target skin clearance but also improving patient-reported outcomes

Allergen sensitization stratifies IL-31 production by memory T cells in atopic dermatitis patients

Background:The role of allergen sensitization in IL-31 production by T cells and specifically in the clinical context of atopic dermatitis (AD) has not been characterized. MethodsThe response to house dust mite (HDM) in purified memory T cells cocultured with epidermal cells from AD patients (n=58) and control subjects (n=11) was evaluated. AD-associated cytokines from culture supernatants, plasma proteins and mRNA expression from cutaneous lesions were assessed and related with the clinical features of the patients. ResultsHDM-induced IL-31 production by memory T cells defined two subsets of AD patients according to the presence or absence of IL-31 response. Patients in the IL-31 producing group showed a more inflammatory profile, and increased HDM-specific (sp) and total IgE levels compared to the IL-31 non-producing group. A correlation between IL-31 production and patient's pruritus intensity, plasma CCL27 and periostin was detected. When the same patients were analyzed based on sp IgE and total IgE levels, an increased IL-31 in vitro response, as well as type 2 markers in plasma and cutaneous lesions, was found in patients with sp IgE levels > 100 kUA/L and total IgE levels > 1000 kU/L. The IL-31 response by memory T cells was restricted to the cutaneous lymphocyte-associated antigen (CLA)(+) T-cell subset. ConclusionIgE sensitization to HDM allows stratifying IL-31 production by memory T cells in AD patients and relating it to particular clinical phenotypes of the disease

Treatment of atopic dermatitis with abrocitinib in real practice in Spain: efficacy and safety results from a 24-week multicenter study

Background: Abrocitinib, a selective JAK 1 inhibitor, was recently approved in Europe. Despite its approval, real-world data on its efficacy and safety in treating moderate-to-severe atopic dermatitis (AD) remains limited. Objectives: This study aimed to evaluate the short-term effectiveness and safety of abrocitinib in a real-life setting for patients with moderate-to-severe AD. Methods: We conducted a retrospective multicenter study involving adult patients with moderate-to-severe AD who started abrocitinib treatment between May 1, 2023, and September 30, 2023, in 15 Spanish hospitals. Treatment doses were 100 or 200 mg daily, based on clinical assessment. Data collection included patient demographics, AD history, comorbidities, previous treatments, and disease severity indicators such as SCORing atopic dermatitis (SCORAD), Eczema Area and Severity Index (EASI), body surface area, and Peak Pruritus NRS scores at baseline, 4, 12, and 24 weeks. Quality of life was measured using the Dermatology Life Quality Index (DLQI), and safety was assessed by monitoring adverse reactions and various biochemical parameters. Results: The cohort comprised 76 patients with an average age of 33.93 years; 57.89% were male. Before abrocitinib, 36.84% were naïve to advanced therapies. The baseline mean scores were SCORAD 47.04, EASI 21.79, and DLQI 15.01. At Week 24, there were significant improvements: EASI was reduced to 2.81, and 70.58% of the patients achieved EASI 75. However, 18.42% discontinued treatment mainly due to inefficacy or adverse effects. The safety profile was favorable, with 22.37% reporting mild adverse events (AEs) and one serious case of cutaneous lymphoma. Conclusions: This first Spanish series assessing abrocitinib in real-world conditions reveals a significant improvement in AD symptoms and quality of life in a range of severity and prior treatment failures. Abrocitinib was well-tolerated, with few serious AEs, highlighting its potential as an effective treatment option for AD.7 página

Google search trends for itch in Europe : a retrospective longitudinal study

Altres ajuts: European Academy of Dermatology and Venereology (EADV, No. 2016-012 to MP).Background: Itch is a common symptom in the general population. Affected individuals often do not seek medical consultation and rely on Internet searches to obtain information regarding their itch. Objectives: The aim of this study was to attain insights into common concerns of the general population regarding itch can by analysing itch-related Internet search behaviour. Methods: Google AdWords Keyword Planner was used to assess search volumes for itch-related terms in 15 European countries between September 2014 and August 2018. All identified keywords were qualitatively categorized. Itch-related terms were descriptively analysed and are shown as number of searches/100 000 inhabitants. Results: The search volume for the keyword 'itch' per 100 000 inhabitants was highest in Northern Europe, followed by Eastern, Central and Southern Europe. In 4/15 countries, itch was searched for more often in the autumn/winter months compared to in the spring/summer months. Most itch-related terms were related to dermatological conditions such as inflammatory skin diseases (e.g. psoriasis, atopic dermatitis), allergic or immunologic conditions (e.g. urticaria), and infectious diseases or infestations (e.g. scabies). In terms of body location, genitoanal itch dominated the searches. Symptoms and signs related to itch, possible non-dermatological aetiologies, and treatment options were also among the most searched terms. Conclusions: These analyses provided for the first time insights into the search behaviour patterns related to itch across Europe. People from Northern and Eastern Europe are more likely to seek online information regarding itch. Causes for the itch, especially dermatological conditions, and genitoanal itch are the most important concerns for Internet users. This unconventional and inexpensive method identifies medical needs of people beyond the medical setting, including people who do not seek medical consultation. Accordingly, the data could be used to guide public health interventions and manage respective inhabitants' medical needs

Treatment of Severe Atopic Dermatitis With Upadacitinib in Clinical Practice: Short-Term Efficacy and Safety Results

Introduction: Death with a functioning graft (DWFG) is the most frequent cause of loss of kidney transplantation (KT). Objective: To analyze the evolution of the causes of DWFG and the frequency of the types of cancer causing DWFG. Methods: Retrospective study of KT in Andalusia from 1984 to 2018. We analyzed the evolution according to eras (1984-1995; 1996-2007; 2008-2018) and according to post-transplant period (early death: first year post-KT; late death: after first year post-KT). Results: A total of 9905 KT were performed, registering 1861 DWFG. The most frequent causes were cardiovascular disease (25.1%), infections (21.5%) and cancer (19.9%). In early death we did not observe changes, and infections were always the main cause. In late death, cardiovascular death decreased (1984-1995: 35.2%, 1996-2007: 22.6%, 2008-2018: 23.9%), but infections (1984-1995: 12.5%, 1996-2007: 18.3%, 2008-2018: 19.9%) and, above all, cancer-related deaths increased (1984-1995: 21.8%, 1996-2007: 29%, 2008-2018: 26.8%) (P < .001). In the multivariable analysis for late death due to cardiovascular disease, recipient age, retransplantation, diabetes, and the first period were risk factors, while the risk of late death due to cancer and infections was associated with recent eras. In the first year after transplantation, the most frequent neoplasia causing DWFG was post-transplant lymphoproliferative disease, and after the first year, it was lung cancer, without differences when it was analyzed by eras. Conclusions: Despite the greater comorbidity of the recipients, cardiovascular deaths have decreased. Cancer has been the main cause of late death in recent years. Lung cancer is the most frequent malignancy that causes DWFG in our transplant patients

Chronic nodular prurigo: clinical profile and burden. A European cross-sectional study

Background: Chronic nodular prurigo (CNPG) is a condition characterized by chronic itch, a prolonged scratching behaviour and the presence of pruriginous nodules. A comprehensive understanding of this condition, especially regarding its clinical characteristics and impact on quality of life is still lacking. Objectives: Aim of this pan-European multicentre cross-sectional study was to establish the clinical profile of CNPG, including its associated burden. Methods: Fifteen centres from 12 European countries recruited CNPG patients presenting at the centre or using the centres' own databases. Patients were asked to complete a questionnaire in paper or electronic format. Demography, current co-morbidities, underlying disease, itch intensity, additional sensory symptoms, quality of life, highest burden and emotional experience of itch were assessed. Results: A total of 509 patients (210 male, median age: 64&nbsp;years [52; 72]) were enrolled. Of these, 406 reported itch and CNPG lesions in the previous 7&nbsp;days and qualified to complete the whole questionnaire. We recorded moderate to severe worst itch intensity scores in the previous 24&nbsp;h. Scores were higher in patients with lower educational levels and those coming from Eastern or Southern Europe. Most patients experience itch often or always (71%) and report that their everyday life is negatively affected (53%). Itch intensity was considered to be the most burdensome aspect of the disease by 49% of the patients, followed by the visibility of skin lesions (21%) and bleeding of lesions (21%). The majority of patients was unaware of an underlying condition contributing to CNPG (64%), while psychiatric diseases were the conditions most often mentioned in association with CNPG (19%). Conclusions: This multicentre cross-sectional study shows that itch is the dominant symptom in CNPG and reveals that the profile of the disease is similar throughout Europe
