Hereditary Angioedema (HAE) is a rare and disabling disease. Early diagnosis and appropriate therapy are essential. This update and revision of the global guideline for HAE provides up‐to‐date ...consensus recommendations for the management of HAE. In the development of this update and revision of the guideline, an international expert panel reviewed the existing evidence and developed 20 recommendations that were discussed, finalized and consented during the guideline consensus conference in June 2016 in Vienna. The final version of this update and revision of the guideline incorporates the contributions of a board of expert reviewers and the endorsing societies. The goal of this guideline update and revision is to provide clinicians and their patients with guidance that will assist them in making rational decisions in the management of HAE with deficient C1‐inhibitor (type 1) and HAE with dysfunctional C1‐inhibitor (type 2). The key clinical questions covered by these recommendations are: (1) How should HAE‐1/2 be defined and classified?, (2) How should HAE‐1/2 be diagnosed?, (3) Should HAE‐1/2 patients receive prophylactic and/or on‐demand treatment and what treatment options should be used?, (4) Should HAE‐1/2 management be different for special HAE‐1/2 patient groups such as pregnant/lactating women or children?, and (5) Should HAE‐1/2 management incorporate self‐administration of therapies and patient support measures?
Summary
Knowledge about the development of untreated actinic keratosis (AK) and risk of progression into squamous cell carcinoma (SCC) is important. Therefore, we set out to synthesize primary data ...on the natural history of AK. We carried out a systematic literature search (Medline, Medline in Process, Embase, Cochrane) of studies on the natural course of AK, regarding (i) progression and regression rates per lesion‐year, (ii) changes in total lesion counts over time, and (iii) spontaneous field regression and recurrence rates, taking into account studies on participants without immunosuppression and history of skin cancer, immunosuppressed patients and participants with a history of skin cancer and sunscreen use. Twenty‐four eligible studies were identified providing data on at least one of the outcomes. Progression rates of AK to SCC ranged from 0% to 0·075% per lesion‐year, with a risk of up to 0·53% per lesion in patients with prior history of nonmelanoma skin cancer. Rates of regression of single lesions ranged between 15% and 63% after 1 year. The data available on recurrence rates of single lesions 1 year after regression indicate a recurrence rate of 15–53%. Data on the relative change of total AK count over time are heterogeneous, and range from −53% to +99·1%. Spontaneous complete field regression rates range from 0% to 21%, with recurrences in 57%. In general, the available data are limited. Important methodological limitations apply. Currently, no reliable estimates concerning the frequency of AK developing into invasive carcinoma can be given, and further studies are needed.
What's already known about this topic?
Actinic keratosis (AK) is a common skin lesion with the potential of malignant progression.
Progression and regression rates are a matter of debate, and available data have not been summarized systematically.
What does this study add?
Rates of progression of single AKs into squamous cell carcinoma range between 0% and 0·53% per year, but due to methodological limitations in the identified publications, any estimate of progression rates remains highly uncertain.
Rates of regression of single lesions ranged between 15% and 63% per year, with recurrence rates of 15–53%.
Spontaneous complete field regression of observed fields on the face and scalp occurred in 0–7·2% of patients.
The evidence‐ and consensus‐based guideline on atopic eczema was developed in accordance with the EuroGuiDerm Guideline and Consensus Statement Development Manual. Four consensus conferences were ...held between December 2020 and July 2021. Twenty‐nine experts (including clinicians and patient representatives) from 12 European countries participated. This first part of the guideline includes general information on its scope and purpose, the health questions covered, target users and a methods section. It also provides guidance on which patients should be treated with systemic therapies, as well as recommendations and detailed information on each systemic drug. The systemic treatment options discussed in the guideline comprise conventional immunosuppressive drugs (azathioprine, ciclosporin, glucocorticosteroids, methotrexate and mycophenolate mofetil), biologics (dupilumab, lebrikizumab, nemolizumab, omalizumab and tralokinumab) and janus kinase inhibitors (abrocitinib, baricitinib and upadacitinib). Part two of the guideline will address avoidance of provocation factors, dietary interventions, immunotherapy, complementary medicine, educational interventions, occupational and psychodermatological aspects, patient perspective and considerations for paediatric, adolescent, pregnant and breastfeeding patients.
Summary
Dermatologists may choose from various conventional and biological systemic agents to treat patients with moderate‐to‐severe psoriasis. We set out to analyse systematically the efficacy and ...tolerability of approved treatments for moderate‐to‐severe psoriasis. We undertook a systematic review and meta‐analysis of randomized controlled trials (RCTs) investigating the efficacy of systemic treatment approved for moderate‐to‐severe psoriasis. Efficacy was assessed as the proportion of participants with 75% improvement in Psoriasis Area and Severity Index at primary efficacy measurement (week 8–16). Safety was summarized as rates of adverse events and withdrawals. Direct and indirect comparative efficacy was assessed by random effects meta‐analysis of risk differences (RDs). In total, 48 eligible RCTs totalling 16 696 patients (11 178 randomized to biologics, 1888 to conventional treatments) were identified. In placebo‐controlled trials, infliximab was the most efficacious RD 76%, 95% confidence interval (CI) 73–79%. Adalimumab (RD 61%, 95% CI 56–67%), and ustekinumab 45 mg (RD 63%, 95% CI 59–66%) and 90 mg (RD 67%, 95% CI 60–74%) each had similar efficacy. These biologics are more effective than etanercept and all conventional treatments. Head‐to‐head trials indicate the superiority of adalimumab and infliximab over methotrexate (MTX), the superiority of ustekinumab over etanercept, the nonsignificant superiority of ciclosporin over MTX, and the dose‐dependent efficacy of etanercept and ustekinumab. Fumaric acid is as efficacious as MTX. Safety of treatments could not be pooled due to a lack of standardization in reporting across trials. In conclusion, the qualitative and quantitative evidence is much stronger for biological interventions than for conventional treatments.
What's already known about this topic?
Direct comparisons of the different treatment options available for psoriasis are scarce, and most studies were done on a verum vs. placebo basis.
Safety data have been reported in most trials, but systematic summaries of the safety data for patients with psoriasis are scarce.
In previous reviews, biological treatments did not appear to be generally superior to conventional systemic treatments.
What does this study add?
This review identifies infliximab, adalimumab and ustekinumab as the most efficacious treatments during induction therapy.
Some additional evidence has been generated for the conventional systemic antipsoriatics, but evidence remains better for biologics.
Due to the heterogeneity in study reporting, a direct or indirect comparison of safety data is very difficult to achieve, and there is a strong need to standardize safety reporting in psoriasis trials.
Patients with moderate to severe psoriasis are undertreated. To solve this persistent problem, the consensus programme was performed to define goals for treatment of plaque psoriasis with systemic ...therapy and to improve patient care. An expert consensus meeting and a collaborative Delphi procedure were carried out. Nineteen dermatologists from different European countries met for a face-to-face discussion and defined items through a four-round Delphi process. Severity of plaque psoriasis was graded into mild and moderate to severe disease. Mild disease was defined as body surface area (BSA) ≤10 and psoriasis area and severity index (PASI) ≤10 and dermatology life quality index (DLQI) ≤10 and moderate to severe psoriasis as (BSA > 10 or PASI > 10) and DLQI > 10. Special clinical situations may change mild psoriasis to moderate to severe including involvement of visible areas or severe nail involvement. For systemic therapy of plaque psoriasis two treatment phases were defined: (1) induction phase as the treatment period until week 16; however, depending on the type of drug and dose regimen used, this phase may be extended until week 24 and (2) maintenance phase for all drugs was defined as the treatment period after the induction phase. For the definition of treatment goals in plaque psoriasis, the change of PASI from baseline until the time of evaluation (ΔPASI) and the absolute DLQI were used. After induction and during maintenance therapy, treatment can be continued if reduction in PASI is ≥75%. The treatment regimen should be modified if improvement of PASI is <50%. In a situation where the therapeutic response improved ≥50% but <75%, as assessed by PASI, therapy should be modified if the DLQI is >5 but can be continued if the DLQI is ≤5. This programme defines the severity of plaque psoriasis for the first time using a formal consensus of 19 European experts. In addition, treatment goals for moderate to severe disease were established. Implementation of treatment goals in the daily management of psoriasis will improve patient care and mitigate the problem of undertreatment. It is planned to evaluate the implementation of these treatment goals in a subsequent programme involving patients and physicians.
Androgenetic alopecia is the most common hair loss disorder, affecting both men and women. Initial signs of androgenetic alopecia usually develop during teenage years leading to progressive hair loss ...with a pattern distribution. Moreover, its frequency increases with age and affects up to 80% Caucasian men and 42% of women. Patients afflicted with androgenetic alopecia may undergo significant impairment of quality of life. The European Dermatology Forum (EDF) initiated a project to develop evidence‐based guidelines for the treatment of androgenetic alopecia. Based on a systematic literature research the efficacy of the currently available therapeutic options was assessed and therapeutic recommendations were passed in a consensus conference. The purpose of the guideline is to provide dermatologists with an evidence‐based tool for choosing an efficacious and safe therapy for patients with androgenetic alopecia.
The evidence‐ and consensus‐based guideline on atopic eczema was developed in accordance with the EuroGuiDerm Guideline and Consensus Statement Development Manual. Four consensus conferences were ...held between December 2020 and July 2021. Twenty‐nine experts (including clinicians and patient representatives) from 12 European countries participated. This second part of the guideline includes recommendations and detailed information on basic therapy with emollients and moisturizers, topical anti‐inflammatory treatment, antimicrobial and antipruritic treatment and UV phototherapy. Furthermore, this part of the guideline covers techniques for avoiding provocation factors, as well as dietary interventions, immunotherapy, complementary medicine and educational interventions for patients with atopic eczema and deals with occupational and psychodermatological aspects of the disease. It also contains guidance on treatment for paediatric and adolescent patients and pregnant or breastfeeding women, as well as considerations for patients who want to have a child. A chapter on the patient perspective is also provided. The first part of the guideline, published separately, contains recommendations and guidance on systemic treatment with conventional immunosuppressive drugs, biologics and janus kinase (JAK) inhibitors, as well as information on the scope and purpose of the guideline, and a section on guideline methodology.
Background
There is limited information on systemic and biological treatment optimization and transitioning in routine clinical practice.
Objective
To provide practical guidance on treatment ...optimization and transitioning for moderate‐to‐severe plaque psoriasis.
Methods
Dermatologists from 33 countries contributed to the Transitioning Therapies programme. Fourteen questions were identified. Answers were drafted based on systematic literature reviews (7/14 questions) and expert opinion (7/14 questions). Using a modified Delphi procedure, dermatologists from 30 countries voted on their level of agreement with each draft answer (scale: 1–9, strong disagreement to strong agreement). Consensus was defined as ≥75% of participants scoring within the 7–9 range.
Results
Consensus was achieved on the answers to all questions. Recommendations for the use of cyclosporine and methotrexate were agreed. Transitioning from a conventional systemic therapy to a biological agent may be done directly or with an overlap (if transitioning is required because of lack of efficacy) or potentially with a treatment‐free interval (if transitioning is required for safety reasons). Combination therapy may be beneficial. Continuous therapy for patients on biologicals is strongly recommended. However, during successful maintenance with biological monotherapy, a dosage reduction may be considered to limit drug exposure, although this may carry the risk of decreased efficacy. Switching biologicals for reasons of efficacy should be done without a washout period, but switching for reasons of safety may require a treatment‐free interval.
Conclusion
This consensus provides practical guidance on treatment optimization and transitioning for moderate‐to‐severe plaque psoriasis, based on literature reviews and the expert opinion of dermatologists from across the globe.
