Which emollients are effective and acceptable for eczema in children?

Eczema is a chronic skin disease characterised by dry skin, intense itching, inflammatory skin lesions, and a considerable impact on quality of life. Moisturisation is an integral part of treatment, but it is unclear if moisturisers are effective.

Eczema is a common condition, yet there are uncertainties regarding many frequently used treatments. Knowing which of these uncertainties matter to patients and clinicians is important, because they are likely to have different priorities from those of researchers and funders. To identify the uncertainties in eczema treatment that are important to patients who have eczema, their carers and the healthcare professionals (HCPs) who treat them. An eczema Priority Setting Partnership was established, including patients, HCPs and researchers. Eczema treatment uncertainties were gathered from patients and clinicians, and then prioritized in a transparent process, using a methodology advocated by the James Lind Alliance. In the consultation stage 493 participants (including 341 patients/carers) made 1070 submissions, of which 718 were uncertainties relating to the treatment of eczema. Treatment uncertainties with more than one submission were grouped into 52 'indicative uncertainties', which were then ranked by 514 participants (including 399 patients/carers). The top 14 treatment uncertainties were prioritized for research. The first four were common to patients/carers and HCPs (shared uncertainties): (i) the best and safest way of using topical steroids (including frequency of application, potency, length of time, alternation with other topical treatments and age limits); (ii) the long-term safety of topical steroids; (iii) the role of food allergy tests; and (iv) the most effective and safe emollients in treating eczema. The remaining 10 of the top 14 uncertainties comprised the next five highest ranked uncertainties for patients and the next five highest ranked uncertainties for HCPs. At a workshop involving 40 participants (patients, HCPs and researchers), shared uncertainties were formulated into possible research questions. The top 14 treatment uncertainties around the treatment of eczema provide guidance for researchers and funding bodies to ensure that future research answers questions that are important to both clinicians and patients. © 2012 The Authors.

Long-term low-level topical anti-inflammatory therapy has been suggested as a new paradigm in the treatment of atopic eczema (AE). To determine the efficacy and tolerability of topical corticosteroids and calcineurin inhibitors for flare prevention in AE. Systematic review of randomized controlled trials reporting efficacy of topical corticosteroids and/or topical calcineurin inhibitors for flare prevention in AE. Identification of relevant articles by systematic electronic searches (Cochrane Library, Medline) supplemented by hand search. Primary efficacy endpoint: proportion of participants experiencing at least one flare during proactive anti-inflammatory treatment. Relative risks (RRs) and corresponding 95% confidence intervals (CIs) were calculated and pooled by pharmaceutical agent using random-effects meta-analysis. Sensitivity analysis included meta-regression to explore the influence of study-specific covariates. Nine articles reporting on eight vehicle-controlled trials were included. Three, four and one trial(s) evaluated proactive therapy with topical tacrolimus, fluticasone propionate and methylprednisolone aceponate, respectively. Each agent under study was more efficacious to prevent flares than vehicle. Meta-analysis suggested that topical fluticasone propionate (RR 0·46, 95% CI 0·38-0·55) may be more efficacious to prevent disease flares than topical tacrolimus (RR 0·78, 95% CI 0·60-1·00). Meta-regression indicated robustness of these findings. Proactive anti-inflammatory therapy was generally well tolerated. The trials identified, however, do not allow firm conclusions about long-term safety. Vehicle-controlled trials indicate efficacy of proactive treatment with tacrolimus, fluticasone propionate and methylprednisolone aceponate to prevent AE flares. Indirect evidence from vehicle-controlled trials suggests that twice weekly application of the potent topical corticosteroid fluticasone propionate may be more efficacious to prevent AE flares than tacrolimus ointment. Head to head trials should be conducted to confirm these results. Future studies are also needed to evaluate the long-term safety of proactive treatment of AE. © 2010 The Authors.
