Abstract
BACKGROUND: Atopic dermatitis (AD) is a highly prevalent, chronic relapsing condition in childhood with significant financial burden and impact on the quality of life of patients and caregivers. Proactive maintenance treatment with moisturizing agents is the mainstay AD therapy. Objectives: The aim of this study was to assess the cost-effectiveness of a non-steroidal barrier cream (Atopiclair), compared to regular emollient in pediatric patients with mild-to-moderate AD. Methods: A Markov decision model was developed to evaluate the cost-effectiveness of Atopiclair versus regular emollient in 12 Asia-Pacific countries, grouped by income categories based on gross domestic product (GDP) per capita. Data was obtained from structured literature review, expert opinion, fee schedules, and findings from a 2012 survey of 12 Asia-Pacific countries. Analysis was performed a societal perspective. Results: In the base case analysis, Atopiclair was cost-effective against regular emollient, with USD786, USD499, and USD289 in cost savings per year for high, middle, and low-income countries, respectively. Sensitivity analyses showed that Atopiclair remained cost-effective versus regular emollient. Conclusions: Modelling analysis showed that Atopiclair is a cost-effective treatment compared to regular emollient for mild-to-moderate pediatric AD in the countries included in the study.

INTRODUCTION

Atopic dermatitis (AD) is a chronic inflammatory dermatosis with increasing prevalence globally.1-4 Skin barrier repair with moisturizers is the mainstay treatment for AD, especially in the maintenance phase to prevent disease flares.5 Besides regular emollients containing humectants (eg, lactate, glycerine, and urea) specialized nonsteroidal topical barrier-protection creams (STC), have been developed to provide clinical benefits beyond regular moisturizers. 5,6 One such STC is Atopiclair® (Sinclair Pharma/A. Menarini Asia Pacific), a hydrolipidic cream that contains 2% glycyrrhetinic acid, hyaluronic acid, vitis vinifera (grapevine) extract, telmestine, and butyrospermum parkii (shea butter), which promote epidermal barrier repair and have antiinflammatory and anti-pruritic actions.7 While clinical trials had shown that STCs have greater efficacy compared to their vehicle base or basic emollients,8-11 it is unclear if STCs, which are generally costlier compared to regular emollients, are a cost-effective option for AD patients.12 Although the cost-effectiveness of pharmaceutical AD treatments such as topical tacrolimus,13-15 pimecrolimus,16-18 and corticosteroids18,19 have been demonstrated in North America and Europe, the costeffectiveness of STC has not been examined to a great extent.
Although the pattern of AD has been described in the Asia-Pacific region, evidence is limited and AD management practices vary across countries.20,21 A review in developed countries had shown that AD management costs vary widely by disease severity. 22 Information on cost of AD in Asia-Pacific is also scarce. In 2012, a survey was conducted to elicit the disease burden, quality of life (QOL) and cost of AD across 12 Asia-Pacific countries. 23-25 The survey assessed the impact of AD on QOL and financial cost on 1028 parents of children (1 to 16 years) with moderate to severe AD. It showed that at least 42.7% of patients experienced 5 or more flare-ups annually with frequent visits to general practitioners (GPs) and specialists.25 Furthermore, the child’s QOL was positively associated with AD severity, more so in low-income countries.24 Poorer QOL for the child also correlated with greater negative family impact.24
