Background Management of moderate‐to‐severe atopic dermatitis (AD) frequently requires treatment with systemic therapies. Dupilumab is the first biological agent approved for treatment of moderate‐to‐severe AD. Although promising results have appeared in clinical trials, real‐life data on efficacy and safety are lacking. Objectives To assess effectiveness and safety of treatment with dupilumab in the real‐life clinical setting at a Danish tertiary referral centre. Methods All patients with AD treated with dupilumab from October 2017 to October 2018 at Bispebjerg Hospital, Denmark, were included in the study. Patients were evaluated three times: at treatment initiation and at 1 and 3 months after first dupilumab injection. At each visit, disease activity was assessed by severity score (Eczema Area and Severity Index, EASI), patient‐reported outcomes (Dermatology Life Quality Index, DLQI, pruritus and sleep score) and serological markers [immunoglobulin (Ig)E, eosinophil count and lactate dehydrogenase (LDH)]. Results A total of 43 patients were included in the study. The mean reduction in EASI score from baseline was 19.6 points (72.4%) at 1‐month and 22.6 points (76.7%) at 3‐month follow‐up. EASI, DLQI, pruritus score, sleep score, IgE and LDH were all statistically significantly reduced between baseline and 1‐ and 3‐month follow‐up. Mean reductions in EASI score and LDH at 3‐month follow‐up were significantly correlated (P = 0.003). One patient (2.3%) discontinued treatment due to side‐effects, and seven patients (18.4%) developed conjunctivitis during the study period. Conclusion The effectiveness and safety of dupilumab treatment in a real‐life clinical setting are comparable to that of phase 3 clinical trials. LDH is suggested as a potential serological marker predictive of treatment response.
Atopic dermatitis (AD) has considerable multidimensional personal and societal costs. However, the extend to which the patient's work life is affected due to AD is more sparsely described in the literature. The objective of this review was to examine the impact on work life for patients with AD, with a specific focus on choice of education and occupation, sick leave, social compensations and change of job due to AD. A systematic literature search was performed in PubMed, EMBASE and Web og Science up to 7 February 2017 for articles on the impact on work life for patients with AD. Results were summarized taking several measures of study quality into account. The search identified twenty-three articles, whereof five studies assessed the influence of AD on educational or job choice, without any consistent conslusion, while eight of nine studies with respect to sick leave and two on disability pensions found AD to have a negative impact. Studies of change or loss of job and AD showed more diverse results, as not all studies documented a negative effect of AD on work life. Atopic dermatitis imposes a burden extending beyond personal, emotional and financial costs. This review strongly implies that AD affects sick leave, and though not fully clarified, possible also job choice, change or loss of job and even disability pensions for the more severe cases.
The skin microbiota of atopic dermatitis (AD) patients is characterized by increased Staphylococcus aureus colonization, which exacerbates disease symptoms and has been linked to reduced bacterial diversity. Skin bacterial communities in AD patients have mostly been described at family and genus levels, while species-level characterization has been limited. In this study, we investigated the role of the bacteria belonging to the Staphylococcus genus using targeted sequencing of the tuf gene with genus-specific primers. We compared staphylococcal communities on lesional and non-lesional skin of AD patients, as well as AD patients with healthy controls, and determined the absolute abundance of bacteria present at each site. We observed that the staphylococcal community, bacterial alpha diversity, and bacterial densities were similar on lesional and non-lesional skin, whereas AD severity was associated with significant changes in staphylococcal composition. Increased S. aureus, Staphylococcus capitis, and Staphylococcus lugdunensis abundances were correlated with increased severity. Conversely, Staphylococcus hominis abundance was negatively correlated with severity. Furthermore, S. hominis relative abundance was reduced on AD skin compared to healthy skin. In conclusion, various staphylococcal species appear to be important for skin health.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
