    The Economics of Topical Immunomodulators for the Treatment of Atopic Dermatitis

    No full text
    Atopic dermatitis is a common, chronic, relapsing inflammatory skin disease frequently affecting infants and children. The worldwide prevalence of atopic dermatitis is estimated to be 5-20% of the paediatric population. First-line therapy has generally consisted of dry skin care, avoidance of triggers, application of topical corticosteroids, and administration of antihistamines and oral antibacterials. Topical corticosteroids improve the lesions of atopic dermatitis; however, concern on the part of physicians and patients regarding adverse effects has led to reluctance to utilise topical corticosteroids early and especially for prolonged periods. Topical immunomodulators (TIMs), including tacrolimus ointment and pimecrolimus cream, were recently introduced for the treatment of atopic dermatitis. Clinical data show that TIMs are effective in atopic dermatitis, yet do not cause the significant adverse effects associated with topical corticosteroids. Questions remain regarding the place of TIMs as a treatment for atopic dermatitis and how to use them most effectively, from both therapeutic and pharmacoeconomic standpoints. Specifically, two major issues remain unresolved: (i) how TIMs measure up to other therapies, especially topical corticosteroids; and (ii) how members of the TIM drug class compare against each other. Previous research has established that atopic dermatitis has a significant impact on quality of life (QOL) and carries a substantial economic burden. Some studies have also measured the utility of various atopic dermatitis disease states. While there is a need for further research, early economic studies provide evidence that TIMs positively affect the QOL of patients and families. In certain patients, TIMs may be cost effective and have an acceptable incremental cost utility compared with topical corticosteroids. Making cost-effectiveness comparisons between tacrolimus and pimecrolimus is challenging because there are limited head-to-head comparative data. Given currently available efficacy data, the results of one study suggest that tacrolimus may be more cost effective than pimecrolimus in paediatric patients with moderate atopic dermatitis. The full economic and QOL benefits of both agents are yet to be completely understood. The studies reviewed herein are the first to delineate the pharmacoeconomic benefits of TIMs in atopic dermatitis, and lay the foundation for future analyses. TIMs represent an exciting advance in the treatment of atopic dermatitis. Additional research will help determine the proper place of TIMs among the current array of therapeutic options for atopic dermatitis.Atopic-dermatitis, Economic-implications, Immunosuppressants, Pimecrolimus, Quality-of-life, Tacrolimus

    Intermittent therapy for flare prevention and long-term disease control in stabilized atopic dermatitis: A randomized comparison of 3-times-weekly applications of tacrolimus ointment versus vehicle

    Intermittent dosing of a topical calcineurin inhibitor for preventing atopic dermatitis (AD) disease relapse in patients with stabilized AD has not been evaluated. We sought to evaluate the long-term efficacy and safety of 3-times-weekly use of tacrolimus ointment in preventing AD disease relapse. Adult and pediatric patients with moderate to severe AD who were clear of disease after up to 16 weeks of treatment with tacrolimus ointment were randomized in a double-blind fashion to 3-times-weekly treatment with either tacrolimus ointment (0.03% or 0.1%) or vehicle for 40 weeks. The primary end point was the number of flare-free treatment days. A total of 125 patients were randomized to tacrolimus and 72 patients to vehicle. The mean number of flare-free treatment days was 177 for tacrolimus and 134 for vehicle ( P = .003). Median time to first relapse was 169 days for tacrolimus and 43 for vehicle ( P = .037). Generalizability to all patients seen in clinic may be limited because only patients who responded to tacrolimus ointment in the stabilization phase were randomized into the maintenance phase of the trial. Maintenance therapy with tacrolimus ointment was associated with significantly more flare-free days compared with vehicle, and a significantly longer time until first disease relapse

    © Lippincott Williams & Wilkins. Atopic dermatitis (AD) is a pruritic or painful dermatologic disease characterized by xerosis and eczema lesions. The symptoms/signs of AD can significantly impact patients\u27 health-related quality of life (HRQoL). This study aimed to qualitatively explore the adult and adolescent experience of AD. A targeted literature review and qualitative concept elicitation interviews with clinicians (n = 5), adult AD patients (n = 28), and adolescent AD patients (n = 20) were conducted to elicit AD signs/symptoms and HRQoL impacts experienced. Verbatim transcripts were analyzed using thematic analysis. Twenty-nine symptoms/signs of AD were reported, including pruritus, pain, erythema, and xerosis. Atopic dermatitis symptoms/signs were reported to substantially impact HRQoL. Scratching was reported to influence the experience of symptoms and HRQoL impacts. Four proximal impacts (including discomfort and sleep disturbance) were reported. Ten domains of distal impact were reported, including impacts on psychological and social functioning and activities of daily living. A conceptual model was developed to summarize these findings. This study highlights the range of symptoms and HRQoL impacts experienced by adults and adolescents with AD. To our knowledge, this study was first to explore the lived experience of AD in both adult and adolescent patients, providing valuable insight into the relatively unexplored adolescent experience of AD

    Validation of Expert Opinion in Identifying Comorbidities Associated with Atopic Dermatitis/Eczema

    Background: The use of expert opinion is widespread in economic studies of healthcare utilisation; however, few studies have attempted to assess the validity of assumptions derived from such sources. Objective: To examine the use of such expert opinion in determining comorbidities associated with atopic dermatitis/eczema (AD/E), which were assessed as part of a recent third-party payer cost-of-illness study. Design: To identify the disease-related comorbidities that would represent costs associated with AD/E, physicians on an expert panel were asked individually and then collectively to group all International Classification of Diseases, 9th Edition-Clinical Modification (ICD-9-CM) diagnosis codes as Results: The mean prevalence rate of any diagnosis code in the AD/E population was 0.65 +- 1.82% (SD) with a mean odds ratio of 1.81 +- 0.96. Comorbidities considered by the expert panel Conclusions: Comparing the result of consensus panels with actual claims histories validated the use of expert opinion in determining comorbidities associated with AD/E. Expert opinion yielded valid results in terms of identifying comorbidities that manifested frequently and disproportionately in the AD/E population. Limited statistical measurements of comorbidities would have been less specific than expert opinion. Future cost-of-illness studies should consider alternative data sources and methodologies to enhance the validity and importance of expert opinion and to corroborate their findings.Atopic-dermatitis, Cost-of-illness
