    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

    Despite emerging evidence and advances in the management of atopic dermatitis there a lack of consensus regarding the diagnostic criteria, therapeutic approach, method to assess severity, and patient follow-up for this condition. An expert consensus study was conducted to provide recommendations on the management of patients with moderate-to-severe atopic dermatitis. The study used Delphi-like methodology based on a literature review, a summary of the scientific evidence, and a 2-round survey. The agreement of 60 panellists on 21 statements was evaluated. Consensus was predefined as ≥ 80% agreement of all respondents. In the first round 6 statements reached consensus. Unanimous consensus was achieved regarding therapeutic goals and patient satisfaction (maintained in the long term and periodic goals reassessment recommended every 3–6 months). In the second round, half of the statements reached consensus, all related to patient follow-up, treatment goals, and atopic comorbidities. The statements that did not reach consensus were related to diagnosis (biomarkers, allergy, and food testing) and starting patients on conventional systemic treatment rather than advanced treatment. The study assessed expert opinion regarding a variety of topics related to the clinical approach to patients with moderate-to-severe atopic dermatitis, in order to provide guidance on the diagnosis and management of patients with atopic dermatitis.8 página

    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

    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

    Background and objectives: Bexarotene has been approved to treat advanced stage cutaneous T -cell lymphomas (CTCL) since 1999. However, very few data have been published on its long-term safety and efficacy profile. The aim of this study is to determine the tolerability to bexarotene and outcomes by collecting the 2nd largest case series to date on its long-term use vs CTCL. Material and method: This was a multicenter retrospective review of 216 patients with mycosis fungoides (174), or S & eacute;zary syndrome (42) on a 10 -year course of bexarotene alone or in combination with other therapies at 19 tertiary referral teaching hospitals. Results: A total of 133 men (62%) and 83 women (38%) were included, with a mean age of 63.5 year (27 - 95). A total of 45% were on bexarotene monotherapy for the entire study period, 22% started on bexarotene but eventually received an additional therapy, 13% were on another treatment but eventually received bexarotene while the remaining 20% received a combination therapy since the beginning. The median course of treatment was 20.78 months (1 - 114); and the overall response rate, 70.3%. Complete and partial response rates were achieved in 26% and 45% of the patients, respectively. Treatment was well tolerated, being the most common toxicities hypertriglyceridemia (79%), hypercholesterolemia (71%), and hypothyroidism (52%). No treatment -related grade 5 adverse events were reported. Conclusions: Our study confirms bexarotene is a safe and effective therapy for the long-term treatment of CTCL. (c) 2024 AEDV.

    The cohomological reduction method for computing n-dimensional cocyclic matrices

    Full text link
    Provided that a cohomological model for GG is known, we describe a method for constructing a basis for nn-cocycles over GG, from which the whole set of nn-dimensional nn-cocyclic matrices over GG may be straightforwardly calculated. Focusing in the case n=2n=2 (which is of special interest, e.g. for looking for cocyclic Hadamard matrices), this method provides a basis for 2-cocycles in such a way that representative 22-cocycles are calculated all at once, so that there is no need to distinguish between inflation and transgression 2-cocycles (as it has traditionally been the case until now). When n>2n>2, this method provides an uniform way of looking for higher dimensional nn-cocyclic Hadamard matrices for the first time. We illustrate the method with some examples, for n=2,3n=2,3. In particular, we give some examples of improper 3-dimensional 33-cocyclic Hadamard matrices.Comment: 17 pages, 0 figure

    After the meeting held by the Spanish Contact Dermatitis and Skin Allergy Research Group (GEIDAC) back in October 2021, changes were suggested to the Spanish Standard Series patch testing. Hydroxyethyl methacrylate (2% pet.), textile dye mixt (6.6% pet.), linalool hydroperoxide (1% pet.), and limonene hydroperoxide (0.3% pet.) were, then, added to the series that agreed upon in 2016. Ethyldiamine and phenoxyethanol were excluded. Methyldibromoglutaronitrile, the mixture of sesquiterpene lactones, and hydroxyisohexyl 3-cyclohexene (Lyral) were also added to the extended Spanish series of 2022. (c) 2024 AEDV.
