alitretinoin and Dermatitis--Atopic

To report current knowledge on the different clinical phenotypes of adult atopic dermatitis. Possible therapeutic intervention in relation to phenotype is also evaluated.. Atopic dermatitis is a chronic inflammatory disease affecting up to 10% of adults. It can manifest with different clinical phenotypes, causing diagnostic difficulties. Long-term is often required and systemic drugs are needed for moderate-to-severe forms. However, few drugs are registered for atopic dermatitis in many countries. Furthermore, limited data exist regarding the treatment in relation to individual clinical phenotypes.. Currently, the most relevant data are those for cyclosporine, alitretinoin, and dupilumab. Cyclosporine and dupilumab showed to be effective in the treatment of atopic dermatitis, although in trials and real-life experiences the different phenotypes treated are usually not reported. However, cyclosporine appears to be effective in prurigo nodularis. Alitretinoin is reported to be particularly efficacious for atopic dermatitis of the hands, while it is ineffective for other locations of the disease. Dupilumab demonstrated its efficacy in prurigo nodularis and nummular eczema phenotypes of atopic dermatitis; moreover, especially in elderly patients, its effectiveness seems to be faster if the folds of the limbs are involved.

The treatment of hand eczema represents a great challenge in the daily clinical practice for dermatologists. There are various forms of local, physical and systemic treatment, such as alitretinoin which is the only registered systemic treatment option for severe chronic hand eczema. In 2017 dupilumab was approved for the treatment of moderate to severe atopic dermatitis and can theoretically also be applied for atopic hand eczema. The first and most important step in treatment is to identify the underlying etiology of the hand eczema with the appropriate diagnostic measures, ranging from skin biopsy to allergy testing including occupational products. An important component of treatment is the basic treatment in the form of consistent and stage-adapted skin care. Treatment of hand eczema should follow a step by step procedure whereby the basic treatment should be maintained and, depending on the etiology and clinical type, should be supplemented by topical, systemic and physical treatment forms, also often used in parallel. Mild to moderate forms of hand eczema are usually treated with the basic treatment, emollients and topical glucocorticoids according to various guidelines. In moderate to severe forms of hand eczema UV phototherapy and systemic treatment should be implemented. This article summarizes the most important treatment modalities based on case reports and series, clinical studies, guidelines and expert recommendations.

Systemic therapy is required in patients with severe atopic dermatitis (AD) refractory to adequate topical therapy. The aim of a systemic therapy is the rapid and efficient improvement of skin symptoms and pruritus in acute exacerbation and/or the long-term control of severe chronic disease. A number of immunosuppressive and immunomodulating substances are available that may efficiently reduce skin inflammation and thus lead to a relief of symptoms including pruritus. The excellent effects of cyclosporine as short-term as well as maintenance therapy have been documented in several studies in children and adults. Furthermore, other immunosuppressive substances such as azathioprine, mycophenolate mofetil and methotrexate are effective in patients with moderate to severe AD. Intravenous immunoglobulins and γ-interferon exert immunomodulatory effects and thus may improve severe AD. Biological agents are a new approach in AD therapy since they may specifically target cells, cytokines or mediators involved in the pathogenesis of AD.

Effective treatment options for patients with chronic hand eczema (CHE) are scarce. Dupilumab is licensed for the treatment of moderate-to-severe atopic dermatitis and has shown promising results for the treatment of hand eczema in other studies.. To evaluate the efficacy and safety of dupilumab in adult patients with severe CHE (subtypes recurrent vesicular hand eczema or chronic fissured hand eczema) who have an inadequate response/intolerance to alitretinoin, or when alitretinoin is medically inadvisable.. In this 16-week, randomized, double-blind, placebo-controlled proof-of-concept phase IIb trial, patients with severe CHE were randomized 2 : 1 to dupilumab 300 mg or placebo subcutaneously every 2 weeks. Patients visited the outpatient clinic at the initiation of the study drug, and every 4 weeks until 16 weeks of treatment. The primary endpoint was the proportion of patients achieving at least a 75% improvement on the Hand Eczema Severity Index score (HECSI-75) at week 16. Adverse events were monitored during each visit. The study was registered on ClinicalTrials.gov (identifier NCT04512339).. In total, 30 patients were randomized, and 29 patients received the assigned study drug (dupilumab n = 20, placebo n = 9). At week 16, more patients achieved HECSI-75 in the dupilumab group than in the placebo group {95% [95% confidence interval (CI) 73.1-99.7] vs. 33% [95% CI 9.0-69.1]}. Dupilumab also showed greater least square mean percentage change from baseline to week 16 in peak pruritus Numerical Rating Scale compared with placebo [-66.5 ± 10.7 (95% CI -88.6 to -44.5) vs. -25.3 ± 17.0 (95% CI -60.1-9.4)]. Adverse events were similar for the dupilumab and placebo groups and were mostly mild. There were no serious adverse events, nor did any of the adverse events lead to discontinuation of the study drug.. Dupilumab was efficacious and well tolerated. Larger studies of longer duration are needed to provide more evidence on the -efficacy of dupilumab in CHE. Moreover, larger studies could also enable comparisons between clinical subtypes or aetiological -diagnoses.

The goal of clinical registries is to document the use and effectiveness of therapeutic interventions under real-life conditions. They are an indispensable prerequisite of evidence-based health care.. Initiated in 2011, the German Atopic Dermatitis Registry TREATgermany is the first registry of patients with severe atopic dermatitis worldwide. Adults with severe atopic dermatitis (current/prior systemic antiinflammatory treatment and/or objective SCORAD ≥ 40) are prospectively followed over the course of 24 months. Employed treatment modalities are documented, and validated measuring tools are used to assess clinical disease severity (EASI, objective SCORAD), quality of life (DLQI), symptoms (POEM), global disease severity, as well as patient satisfaction. Herein, we describe the characteristics, therapeutic selection, and effectiveness of systemic antiinflammatory treatments of patients enrolled in the registry until October 2014.. Overall, 78 individuals (mean age 39 years, 61 % men) were enrolled at five recruitment centers. Patients frequently made use of inpatient and outpatient services. Not only was cyclosporine the most frequently administered systemic treatment, but also the most effective (EASI 50 response rate 51 %; EASI 75 response rate 34 % at 12 weeks). Azathioprine, methotrexate, oral prednisolone, mycophenolate, alitretinoin, and leflunomide were also used in some patients.. The present analysis of the German Atopic Dermatitis Registry provides important data with respect to current medical care of adults with severe atopic dermatitis in Germany. It shows the high disease burden, the benefits of current treatment options, and the need for additional effective and safe long-term treatment options.
