Abstract
BACKGROUND Eczema (atopic dermatitis) is the most burdensome skin condition worldwide and cannot currently be prevented or cured. Topical anti-inflammatory treatments are used to control eczema symptoms, but there is uncertainty about the relative effectiveness and safety of different topical anti-inflammatory treatments. OBJECTIVES To compare and rank the efficacy and safety of topical anti-inflammatory treatments for people with eczema using a network meta-analysis. SEARCH METHODS We searched the Cochrane Skin Specialised Register, CENTRAL, MEDLINE, Embase and trial registries on 29 June 2023, and checked the reference lists of included studies. SELECTION CRITERIA We included within-participant or between-participant randomised controlled trials (RCTs) in people of any age with eczema of any severity, but excluded trials in clinically infected eczema, seborrhoeic eczema, contact eczema, or hand eczema. We included topical anti-inflammatory treatments used for at least one week, compared with another anti-inflammatory treatment, no treatment, or vehicle/placebo. Vehicle is a 'carrier system' for an active pharmaceutical substance, which may also be used on its own as an emollient for dry skin. We excluded trials of topical antibiotics used alone, complementary therapies, emollients used alone, phototherapy, wet wraps, and systemic treatments. DATA COLLECTION AND ANALYSIS We used standard Cochrane methods. Primary outcomes were patient-reported eczema symptoms, clinician-reported eczema signs and investigator global assessment. Secondary outcomes were health-related quality of life, long-term control of eczema, withdrawal from treatment/study, and local adverse effects (application-site reactions, pigmentation changes and skin thinning/atrophy were identified as important concerns through patient and public involvement). We used CINeMA to quantify our confidence in the evidence for each outcome. MAIN RESULTS We included 291 studies involving 45,846 participants with the full spectrum of eczema severity, mainly conducted in high-income countries in secondary care settings. Most studies included adults, with only 31 studies limited to children aged < 12 years. Studies usually included male and female participants, multiple ethnic groups but predominantly white populations. Most studies were industry-funded (68%) or did not report their funding sources/details. Treatment duration and trial participation were a median of 21 and 28 days (ranging from 7 days to 5 years), respectively. Interventions used were topical corticosteroids (TCS) (172), topical calcineurin inhibitors (TCI) (134), phosphodiesterase-4 (PDE-4) inhibitors (55), janus kinase (JAK) inhibitors (30), aryl hydrocarbon receptor activators (10), or other topical agents (21). Comparators included vehicle (170) or other anti-inflammatory treatments. The risk of bias was high in 242 of the 272 (89.0%) trials contributing to data analyses, most commonly due to concerns about selective reporting. Network meta-analysis (NMA) was only possible for short-term outcomes. Patient-reported symptoms NMA of 40 trials (6482 participants) reporting patient-reported symptoms as a binary outcome ranked tacrolimus 0.1% (OR 6.27, 95% CI 1.19 to 32.98), potent TCS (OR 5.99, 95% CI 2.83 to 12.69), and ruxolitinib 1.5% (OR 5.64, 95% CI 1.26 to 25.25) as the most effective, all with low confidence. Mild TCS, roflumilast 0.15%, and crisaborole 2% were the least effective. Class-level sensitivity analysis found potent/very potent TCS had similar effectiveness to potent TCI and was more effective than mild TCI and PDE-4 inhibitors. NMA of 29 trials (3839 participants) reporting patient-reported symptoms as a continuous outcome ranked very potent TCS (SMD -1.99, 95% CI -3.25 to -0.73; low confidence) and tacrolimus 0.03% (SMD -1.57, 95% CI -2.42 to -0.72; moderate confidence) the highest. Direct information for tacrolimus 0.03% was based on one trial of 60 participants at high risk of bias. Roflumilast 0.15%, delgocitinib 0.25% or 0.5%, and tapinarof 1% were the least effective. Class-level sensitivity analysis found potent/very potent TCS had similar effectiveness to potent TCI and JAK inhibitors and mild/moderate TCS was less effective than mild TCI. A further 50 trials (9636 participants) reported patient-reported symptoms as a continuous outcome but could not be included in NMA. Clinician-reported signs NMA of 32 trials (4121 participants) reported clinician signs as a binary outcome and ranked potent TCS (OR 8.15, 95% CI 4.99, 13.57), tacrolimus 0.1% (OR 8.06, 95% CI 3.30, 19.67), ruxolitinib 1.5% (OR 7.72, 95% CI 4.92, 12.10), and delgocitinib 0.5% (OR 7.61, 95% CI 3.72, 15.58) as most effective, all with moderate confidence. Mild TCS, roflumilast 0.15%, crisaborole 2%, and tapinarof 1% were the least effective. Class-level sensitivity analysis found potent/very potent TCS more effective than potent TCI, mild TCI, JAK inhibitors, PDE-4 inhibitors; and mild TCS and PDE-4 inhibitors had similar effectiveness. NMA of 49 trials (5261 participants) reported clinician signs as a continuous outcome and ranked tacrolimus 0.03% (SMD -2.69, 95% CI -3.36, -2.02) and very potent TCS (SMD -1.87, 95% CI -2.69, -1.05) as most effective, both with moderate confidence; roflumilast 0.15%, difamilast 0.3% and tapinarof 1% were ranked as least effective. Direct information for tacrolimus 0.03% was based on one trial in 60 participants with a high risk of bias. For some sensitivity analyses, potent TCS, tacrolimus 0.1%, ruxolitinib 1.5%, delgocitinib 0.5% and delgocitinib 0.25% became some of the most effective treatments. Class-level analysis found potent/very potent TCS had similar effectiveness to potent TCI and JAK inhibitors, and moderate/mild TCS was more effective than mild TCI. A further 100 trials (22,814 participants) reported clinician signs as a continuous outcome but could not be included in NMA. Investigator Global Assessment NMA of 140 trials (23,383 participants) reported IGA as a binary outcome and ranked ruxolitinib 1.5% (OR 9.34, 95% CI 4.8, 18.18), delgocitinib 0.5% (OR 10.08, 95% CI 2.65, 38.37), delgocitinib 0.25% (OR 6.87, 95% CI 1.79, 26.33), very potent TCS (OR 8.34, 95% CI 4.73, 14.67), potent TCS (OR 5.00, 95% CI 3.80, 6.58), and tacrolimus 0.1% (OR 5.06, 95% CI 3.59, 7.13) as most effective, all with moderate confidence. Mild TCS, crisaborole 2%, pimecrolimus 1%, roflumilast 0.15%, difamilast 0.3% and 1%, and tacrolimus 0.03% were the least effective. In a sensitivity analysis of low risk of bias information (12 trials, 1639 participants), potent TCS, delgocitinib 0.5% and delgocitinib 0.25% were most effective, and pimecrolimus 1%, roflumilast 0.15%, difamilast 1% and difamilast 0.3% least effective. Class-level sensitivity analysis found potent/very potent TCS had similar effectiveness to potent TCI and JAK inhibitors and were more effective than PDE-4 inhibitors; mild/moderate TCS were less effective than potent TCI and had similar effectiveness to mild TCI. Longer-term outcomes over 6 to 12 months showed a possible increase in effectiveness for pimecrolimus 1% versus vehicle (4 trials, 2218 participants) in a pairwise meta-analysis, and greater treatment success with mild/moderate TCS than pimecrolimus 1% (based on 1 trial of 2045 participants). Local adverse effects NMA of 83 trials (18,992 participants, 2424 events) reporting application-site reactions ranked tacrolimus 0.1% (OR 2.2, 95% CI 1.53, 3.17; moderate confidence), crisaborole 2% (OR 2.12, 95% CI 1.18, 3.81; high confidence), tacrolimus 0.03% (OR 1.51, 95%CI 1.10, 2.09; low confidence), and pimecrolimus 1% (OR 1.44, 95% CI 1.01, 2.04; low confidence) as most likely to cause site reactions. Very potent, potent, moderate, and mild TCS were least likely to cause site reactions. NMA of eight trials (1786 participants, 3 events) reporting pigmentation changes found no evidence for increased pigmentation changes with TCS and crisaborole 2%, with low confidence for mild, moderate or potent TCS and moderate confidence for crisaborole 2%. NMA of 25 trials (3691 participants, 36 events) reporting skin thinning found no evidence for increased skin thinning with short-term (median 3 weeks, range 1-16 weeks) use of mild TCS (OR 0.72, 95% CI 0.12, 4.31), moderate TCS (OR 0.91, 95% CI 0.16, 5.33), potent TCS (OR 0.96, 95% CI 0.21, 4.43) or very potent TCS (OR 0.88, 95% CI 0.31, 2.49), all with low confidence. Longer-term outcomes over 6 to 60 months showed increased skin thinning with mild to potent TCS versus TCI (3 trials, 4069 participants, 6 events with TCS). AUTHORS' CONCLUSIONS Potent TCS, JAK inhibitors and tacrolimus 0.1% were consistently ranked as amongst the most effective topical anti-inflammatory treatments for eczema and PDE-4 inhibitors as amongst the least effective. Mild TCS and tapinarof 1% were ranked amongst the least effective treatments in three of five efficacy networks. TCI and crisaborole 2% were ranked most likely to cause local application-site reactions and TCS least likely. We found no evidence for increased skin thinning with short-term TCS but an increase with longer-term TCS.

Abstract
Atopic dermatitis (AD) is a common inflammatory skin condition found worldwide. It impacts patient quality of life (QoL) and is thought to arise as an inflammatory response to epidermal barrier dysfunction and hypersensitivity. AD can lead to large out-of-pocket costs and increased healthcare expenses over a lifetime. An analysis of all randomized control trials conducted since 1990 on topical therapies for AD were reviewed, including 207 trials in the final analysis. It was found that an average of 226 patients were enrolled over 2.43 arms. Common topical treatments included corticosteroids, calcineurin inhibitors, JAK inhibitors, and phosphodiesterase inhibitors. The most utilized tools to identify treatment efficacy were the EASI, IGA, SCORAD, and PGA. There was a paucity of data on trials that evaluated efficacy, QoL, and cost of treatment simultaneously. This review highlights the need for comprehensive trials that evaluate multiple aspects of treatment, including financial cost and QoL impact, to ensure each patient has the best treatment modality for the management of their AD.

Abstract
BACKGROUND Atopic dermatitis (AD) is a common skin condition with multiple topical treatment options, but uncertain comparative effects. OBJECTIVE We sought to systematically synthesize the benefits and harms of AD prescription topical treatments. METHODS For the 2023 American Academy of Allergy, Asthma & Immunology and American College of Allergy, Asthma, and Immunology Joint Task Force on Practice Parameters AD guidelines, we searched MEDLINE, EMBASE, CENTRAL, CINAHL, LILACS, ICTRP, and GREAT databases to September 5, 2022, for randomized trials addressing AD topical treatments. Paired reviewers independently screened records, extracted data, and assessed risk of bias. Random-effects network meta-analyses addressed AD severity, itch, sleep, AD-related quality of life, flares, and harms. The Grading of Recommendations Assessment, Development and Evaluation approach informed certainty of evidence ratings. We classified topical corticosteroids (TCS) using 7 groups-group 1 being most potent. This review is registered in the Open Science Framework (https://osf.io/q5m6s). RESULTS The 219 included trials (43,123 patients) evaluated 68 interventions. With high-certainty evidence, pimecrolimus improved 6 of 7 outcomes-among the best for 2; high-dose tacrolimus (0.1%) improved 5-among the best for 2; low-dose tacrolimus (0.03%) improved 5-among the best for 1. With moderate- to high-certainty evidence, group 5 TCS improved 6-among the best for 3; group 4 TCS and delgocitinib improved 4-among the best for 2; ruxolitinib improved 4-among the best for 1; group 1 TCS improved 3-among the best for 2. These interventions did not increase harm. Crisaborole and difamilast were intermediately effective, but with uncertain harm. Topical antibiotics alone or in combination may be among the least effective. To maintain AD control, group 5 TCS were among the most effective, followed by tacrolimus and pimecrolimus. CONCLUSIONS For individuals with AD, pimecrolimus, tacrolimus, and moderate-potency TCS are among the most effective in improving and maintaining multiple AD outcomes. Topical antibiotics may be among the least effective.

[PMID: 37075252 DOI: 10.1111/bcp.15751] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Revised: 03/08/2023] [Accepted: 03/28/2023] [Indexed: 04/21/2023] Open
Abstract
AIM New topical agents have been developed for the treatment of atopic dermatitis (AD) in recent years. This systematic review is intended to synthesize the clinical trial literature and concisely report the updated safety and adverse effects of topical medications used to treat atopic dermatitis in children. METHODS A systematic search of Cochrane Library, Embase, PubMed and ClinicalTrials.gov from inception to March 2022 was conducted for trials of topical medications used to treat AD in patients <18 years (PROSPERO #CRD42022315355). Included records were limited to English-language publications and studies of ≥3 weeks duration. Phase 1 studies and those that lacked separate paediatric safety reporting were excluded. RESULTS A total of 5005 records were screened; 75 records met inclusion criteria with 15 845 paediatric patients treated with tacrolimus, 12 851 treated with pimecrolimus, 3539 with topical corticosteroid (TCS), 700 with crisaborole and 202 with delgocitinib. Safety data was well reported in tacrolimus trials with the most frequently reported adverse events being burning sensation, pruritus and cutaneous infections. Two longitudinal cohort studies were included, one for tacrolimus and one for pimecrolimus, which found no significant increased risk of malignancy with topical calcineurin inhibitor (TCI) use in children. Skin atrophy was identified as an adverse event in TCS trials, which other medications did not. Systemic adverse events for the medications were largely common childhood ailments. CONCLUSION Data discussed here support the use of steroid-sparing medications (tacrolimus, pimecrolimus, crisaborole, delgocitinib) as safe options with minimal adverse events for managing paediatric AD, although a larger number of TCI studies reported burning and pruritus compared to TCS studies. TCS was the only medication class associated with reports of skin atrophy in this review. The tolerability of these adverse events should be considered when treating young children. This review was limited to English-language publications and the variable safety reporting of trial investigators. Many newer medications were not included due to pooled adult and paediatric safety data that did not meet inclusion criteria.

Abstract
Introduction Epidermal barrier dysfunction in children with atopic dermatitis can cause transcutaneous sensitization to allergens and allergic diseases. We evaluated the effectiveness of an early-intervention algorithm for atopic dermatitis treatment, utilizing pimecrolimus for long-term maintenance therapy, in reducing transcutaneous sensitization in infants. Method This was a single-center cohort observational study that enrolled children aged 1-4 months with family history of allergic diseases, moderate-to-severe atopic dermatitis, and sensitization to ≥ 1 of the investigated allergens. Patients who sought medical attention at atopic dermatitis onset (within 10 days) were group 1 "baseline therapy with topical glucocorticoids with subsequent transition to pimecrolimus as maintenance therapy"; patients who sought medical attention later were group 2 "baseline and maintenance therapy with topical glucocorticoids, without subsequent use of pimecrolimus". Sensitization class and level of allergen-specific immunoglobulin E were determined at baseline, and 6 and 12 months of age. Atopic dermatitis severity was evaluated using the Eczema Area and Severity Index score at baseline and 6, 9 and 12 months of age. Results Fifty-six and 52 patients were enrolled in groups 1 and 2, respectively. Compared with group 2, group 1 demonstrated a lower level of sensitization to cow's milk protein, egg white and house dust mite allergen at 6 and 12 months of age, and a more pronounced decrease in atopic dermatitis severity at 6, 9 and 12 months of age. No adverse events occurred. Discussion The pimecrolimus-containing algorithm was effective in treating atopic dermatitis and prophylaxis of early forms of allergic diseases in infants. Trial registration https://clinicaltrials.gov/ NCT04900948, retrospectively registered, 25 May 2021.

Abstract
BACKGROUND Atopic dermatitis is a prevalent condition in children and can be effectively managed with medications such as topical calcineurin inhibitors (pimecrolimus or tacrolimus). A key unresolved safety concern is whether use of topical calcineurin inhibitors is associated with cancer. We systematically reviewed the risk of cancer in patients with atopic dermatitis exposed to topical calcineurin inhibitors. METHODS As part of the 2022 American Academy of Allergy, Asthma and Immunology and American College of Allergy, Asthma and Immunology Joint Task Force on Practice Parameters atopic dermatitis guidelines, we searched MEDLINE, Embase, the Latin American and Caribbean Health Sciences Literature database, the Índice Bibliográfico Espanhol de Ciências da Saúde database, the Global Resource of Eczema Trials database, WHO's International Clinical Trials Registry Platform, the US Food and Drug Administration database, the European Medicines Agency database, company registers, and relevant citations from inception to June 6, 2022. We included randomised controlled trials and comparative and non-comparative non-randomised studies in any language addressing cancer risk in patients with atopic dermatitis using topical calcineurin inhibitors. We excluded split-body studies and studies with less than 3 weeks of follow-up. Paired reviewers independently screened records, extracted data, and assessed risk of bias in duplicate. We used Bayesian models to estimate the probability for cancer due to topical calcineurin inhibitor exposure and the GRADE approach to determine the certainty of the evidence. Patients, advocacy groups, and care providers set a priori thresholds of important effects. This study is registered with Open Science Framework, https://osf.io/v4bfc. FINDINGS We identified and analysed 110 unique studies (52 randomised controlled trials and 69 non-randomised studies [11 were non-randomised study extensions of randomised controlled trials]) including 3·4 million patients followed up for a mean of 11 months (range 0·7-120). The absolute risk of any cancer with topical calcineurin inhibitor exposure was not different from controls (absolute risk 4·70 per 1000 with topical calcineurin inhibitors vs 4·56 per 1000 without; odds ratio 1·03 [95% credible interval 0·94-1·11]; moderate certainty). For all age groups and using data from observational studies and randomised controlled trials, the use of pimecrolimus (OR 1·05 [95% credible interval 0·94-1·15]) or tacrolimus (0·99 [0·89-1·09]) is likely to have had little to no association with cancer compared with no topical calcineurin inhibitor exposure. For pimecrolimus versus tacrolimus, the finding was similar (0·95 [95% credible interval 0·83-1·07]). Findings were similar in infants, children, and adults, and robust to trial sequential, subgroup, and sensitivity analyses. INTERPRETATION Among individuals with atopic dermatitis, moderate-certainty evidence shows that topical calcineurin inhibitors do not increase the risk of cancer. These findings support the safe use of topical calcineurin inhibitors in the optimal treatment of patients with atopic dermatitis.

Abstract
Introduction Atopic dermatitis (AD) is a chronic, pruritic, inflammatory skin disease with rising prevalence. Topical corticosteroids (TCS) are recommended as first-line therapy for patients with AD in China; however, corticophobia is a widespread concern, which can manifest as noncompliance: in a previous Chinese study, almost all parents whose children had AD were very concerned about the side effects of TCS and, as a result, nearly half did not use it in the event of recurrence. We propose a TCS-sparing treatment algorithm for the management of infants, children, adolescents, and adults with mild-to-moderate AD, to guide clinical practice in China. Methods A panel of eight experts in AD from China and one expert from Germany formed to develop a practical algorithm for the management of mild-to-moderate AD, focusing on pimecrolimus. Results Irrespective of body location, all patients with mild AD (including acute flares) and infants with moderate AD should apply the topical calcineurin inhibitor (TCI) pimecrolimus twice daily to the affected area until symptoms disappear. For children, adolescents, and adults with moderate AD, pimecrolimus should be applied twice daily to sensitive skin areas, and a TCI (either pimecrolimus or tacrolimus) should be applied twice daily to other body locations. Short-term administration of TCS, followed by TCI twice daily, is recommended for most patients with moderate AD experiencing acute flares, regardless of lesion site. Emollients should be used regularly. Conclusions The algorithm presented intends to simplify treatment of AD in China and guide clinical decision-making.

Abstract
Atopic dermatitis is a chronic relapsing, inflammatory skin disorder associated with skin barrier dysfunction, the prevalence of which has increased dramatically in developing countries. In this article, we propose a treatment algorithm for patients with mild-to-moderate and severe atopic dermatitis flares in daily clinical practice. An international panel of 15 dermatology and allergy experts from eight countries was formed to develop a practical algorithm for the treatment of patients with atopic dermatitis, with a particular focus on topical therapies. In cases of mild-to-moderate atopic dermatitis involving sensitive skin areas, the topical calcineurin inhibitor pimecrolimus should be applied twice daily at the first signs of atopic dermatitis. For other body locations, patients should apply a topical calcineurin inhibitor, either pimecrolimus or tacrolimus, twice daily at the first signs of atopic dermatitis, such as pruritus, or twice weekly in previously affected skin areas. Emollients should be used regularly. Patients experiencing acute atopic dermatitis flares in sensitive skin areas should apply a topical corticosteroid twice daily or alternate once-daily topical corticosteroid/topical calcineurin inhibitor until symptoms improve. Following improvement, topical corticosteroid therapy should be discontinued and patients switched to a topical calcineurin inhibitor. Maintenance therapy should include the use of pimecrolimus once daily for sensitive areas and tacrolimus for other body locations. This treatment algorithm can help guide clinical decision-making in the treatment of atopic dermatitis.

Abstract
Background Atopic eczema (AE) is a chronic, highly pruritic, inflammatory skin condition with increasing prevalence worldwide. Atopic eczema mostly affects children, impairing quality of life with poor disease control leading to progression of other atopic disorders. As most patients in South Africa have no access to specialist healthcare, a practical approach is needed for the management of mild-to-moderate AE in paediatric patients for daily clinical practice. Methods A panel of experts in AE convened to develop a practical algorithm for the management of AE for children and adolescents in South Africa. Results Regular moisturising with an oil-based emollient remains the mainstay of AE treatment. Severe AE flares should be managed with topical corticosteroids (TCSs). For mild-to-moderate AE flares in sensitive skin areas, a topical calcineurin inhibitor (TCI) should be applied twice daily from the first signs of AE until complete resolution. Topical corticosteroids may be used when TCIs are unavailable. In non-sensitive skin areas, TCSs should be used for mild-to-moderate AE, but TCIs twice daily may be considered. Proactive maintenance treatment with low-dose TCI or TCS 2–3 times weekly and the liberal use of emollients is recommended for patients with recurrent flares. Conclusions This algorithm aims to simplify treatment of paediatric AE, optimising clinical outcomes and reducing disease burden. This approach excludes treatment of patients with severe AE, who should be referred to specialist care. Emphasis has been given to the importance of general skincare, patient education and the topical anti-inflammatory medications available in South Africa (TCSs and TCIs).

Abstract
A topical vehicle is a 'carrier system' for an active pharmaceutical (or cosmetic) substance, referred to hereafter as the drug, but a vehicle may also be used on its own as an emollient to ameliorate dry skin. It is well established that the vehicle plays an important role in determining the bioavailability of a given drug at its ultimate target within the skin. Yet in the treatment of atopic eczema/dermatitis (AD), wherein the structure and function of the skin's outer barrier play a pivotal role in the development and course of the condition, the interaction of the vehicle with this barrier carries a particular importance. It is now clear that the often-considered inert excipients of a vehicle bring about changes within the skin at the molecular level that promote barrier restoration and enhance innate immune defenses with therapeutic value to AD patients. Moreover, the vehicle control in randomized controlled trials (RCTs) increasingly displays significant efficacy. In light of this, we consider the implications of vehicle design in relation to AD pathophysiology and the role vehicles play as controls in RCTs of new drug treatments for this condition.

Abstract
Objectives: The Atopic Dermatitis Control Tool (ADCT) was designed to evaluate patient-perceived AD control and facilitate patient-physician discussion on long-term disease control.Methods: The study was performed in adult patients with AD. Development of the ADCT followed US Food and Drug Administration (FDA) guidelines on patient-reported outcome measures (PROMs). Qualitative research, including targeted literature review, interviews with clinical experts, and combined concept elicitation/cognitive debriefing with patients with AD, was conducted to provide a list of comprehensive concepts capturing AD control per physician and patient perspectives. Quantitative methods assessed psychometric properties of the instrument and defined the threshold for AD control.Results: The resulting pilot six-item ADCT, reflecting key concepts related to AD control, had 7-day recall and assessed symptoms and impacts on patients' everyday lives by severity and/or frequency. The ADCT showed good content validity (well understood by adult patients with AD), and quick completion time (<2 min). Psychometric analysis indicated no floor/ceiling effects for response distributions, particularly strong (r ≥ 0.80) inter-item correlations for the six ADCT items, robust construct validity (r > 0.50), and item-level discriminating ability (p < .03); this supported the derivation of a total score based on responses to all items. ADCT total score showed evidence of strong internal consistency reliability (Cronbach's alpha >0.80). A score ≥7 points was identified as an optimum threshold to identify patients whose AD is "not in control."Conclusions: No single validated instrument has been available to holistically evaluate patient-perceived AD control. The newly developed ADCT displays good-to-excellent content validity, construct validity, internal consistency, reliability, and discriminating ability.

Abstract
Ligand-activated plasma membrane receptors follow pathways of endocytosis through the endosomal sorting apparatus. Receptors cluster in clathrin-coated pits that bud inwards and enter the cell as clathrin-coated vesicles. These vesicles travel through the acidic endosome whereby receptors and ligands are sorted to be either recycled or degraded. The traditional paradigm postulated that the endocytosis role lay in signal termination through the removal of the receptor from the cell surface. It is now becoming clear that the internalization process governs more than receptor signal cessation and instead reigns over the entire spatial and temporal wiring of receptor signaling. Governing the localization, the post-translational modifications, and the scaffolding of receptors and downstream signal components established the endosomal platform as the master regulator of receptor function. Confinement of components within or between distinct organelles means that the endosome instructs the cell on how to interpret and translate the signal emanating from any given receptor complex into biological effects. This review explores this emerging paradigm with respect to the cancer-relevant insulin-like growth factor type 1 receptor (IGF-1R) and discusses how this perspective could inform future targeting strategies.

Abstract
INTRODUCTION Treatment guidelines endorse a variety of strategies for atopic dermatitis (AD) which may vary from published data and clinical practice patterns. The objective of this review was to quantify the volume of available medical literature supporting pediatric AD treatments and compare these patterns to those recommended by published guidelines and/or clinical practice patterns. METHODS Searches of Embase (2005-2016) and abstracts from selected meetings (2014-2016) related to AD treatment in patients younger than 17 years of age yielded references that were assessed by study design, primary treatment, age groups, and AD severity. RESULTS Published literature partially supports clinical guidelines, with emollients and topical medications being the most investigated. There were disproportionately more publications for topical calcineurin inhibitors (TCI) compared with topical corticosteroids (TCS); however, the search interval may have biased the results toward treatments approved near the beginning of the time frame. In contrast, publications documenting clinical practice patterns reflect greater use of emollients and TCS (over TCI), as well as systemic corticosteroids. Data is relatively limited for long-term and combination treatment, treatment of severe AD, and patients younger than 2 years of age, and completely lacking for systemic corticosteroids. CONCLUSION This scoping review demonstrates that available medical literature largely supports published guidelines for topical therapy; however, clinical practice patterns are less aligned. There is a lack of data for older, more frequently used generic treatments, including oral antihistamines, oral antibiotics, and systemic corticosteroids. Overall, literature is lacking for long-term treatment, treatment for patients younger than 2 years of age, and for systemic treatment for severe disease. FUNDING Regeneron Pharmaceuticals Inc.

Abstract
OBJECTIVE The objective of this systematic review was to identify and assess the quality of published economic decision-analytic models within atopic eczema against best practice guidelines, with the intention of informing future decision-analytic models within this condition. METHODS A systematic search of the following online databases was performed: MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Central Register of Controlled Trials, Database of Abstracts of Reviews of Effects, Cochrane Database of Systematic Reviews, NHS Economic Evaluation Database, EconLit, Scopus, Health Technology Assessment, Cost-Effectiveness Analysis Registry and Web of Science. Papers were eligible for inclusion if they described a decision-analytic model evaluating both the costs and benefits associated with an intervention or prevention for atopic eczema. Data were extracted using a standardised form by two independent reviewers, whilst quality was assessed using the model-specific Philips criteria. RESULTS Twenty-four models were identified, evaluating either preventions (n = 12) or interventions (n = 12): 14 reported using a Markov modelling approach, four utilised decision trees and one a discrete event simulation, whilst five did not specify the approach. The majority, 22 studies, reported that the intervention was dominant or cost effective, given the assumptions and analytical perspective taken. Notably, the models tended to be short-term (16 used a time horizon of ≤1 year), often providing little justification for the limited time horizon chosen. The methodological and reporting quality of the studies was generally weak, with only seven studies fulfilling more than 50% of their applicable Philips criteria. CONCLUSIONS This is the first systematic review of decision models in eczema. Whilst the majority of models reported favourable outcomes in terms of the cost effectiveness of the new intervention, the usefulness of these findings for decision-making is questionable. In particular, there is considerable scope for increasing the range of interventions evaluated, for improving modelling structures and reporting quality.

This programme addressed four diseases: (1) eczema, (2) vitiligo, (3) squamous cell skin cancer (SCC) and (4) pyoderma gangrenosum (PG).ObjectiveTo set priorities and reduce uncertainties for the treatment and prevention of skin disease in our four chosen diseases.DesignMixed methods including eight systematic reviews, three prioritisation exercises, two pilot randomised controlled trials (RCTs), three feasibility studies, two core outcome initiatives, four funding proposals for national RCTs and one completed national RCT.SettingSecondary care, primary care and the general population.ParticipantsPatients (and their caregivers) with eczema, vitiligo, SCC and PG, plus health-care professionals with an interest in skin disease.InterventionsOur three intervention studies included (1) barrier enhancement using emollients from birth to prevent eczema (pilot RCT); (2) handheld narrowband ultraviolet light B therapy for treating vitiligo (pilot RCT); and (3) oral ciclosporin (Neoral®, Novartis Pharmaceuticals) compared with oral prednisolone for managing PG (pragmatic national RCT).ResultsSystematic reviews included two overarching systematic reviews of RCTs of treatments for eczema and vitiligo, an umbrella review of systematic reviews of interventions for the prevention of eczema, two reviews of treatments for SCC (one included RCTs and the second included observational studies), and three reviews of outcome measures and outcome reporting. Three prioritisation partnership exercises identified 26 priority areas for future research in eczema, vitiligo and SCC. Two international consensus initiatives identified four core domains for future eczema trials and seven core domains for vitiligo trials. Two pilot RCTs and three feasibility studies critically informed development of four trial proposals for external funding, three of which are now funded and one is pending consideration by funders. Our pragmatic RCT tested the two commonly used systemic treatments for PG (prednisolone vs. ciclosporin) and found no difference in their clinical effectiveness or cost-effectiveness. Both drugs showed limited benefit. Only half of the participants’ ulcers had healed by 6 months. For those with healed ulcers, recurrence was common (30%). Different side effect profiles were noted for each drug, which can inform clinical decisions on an individual patient basis. Three researchers were trained to PhD level and a dermatology patient panel was established to ensure patient involvement in all aspects of the programme.ConclusionsFindings from this programme of work have already informed clinical guidelines and patient information resources. Feasibility studies have ensured that large national pragmatic trials will now be conducted on important areas of treatment uncertainty that address the needs of patients and the NHS. There is scope for considerable improvement in terms of trial design, conduct and reporting for RCTs of skin disease, which can be improved through wider collaboration, registration of trial protocols and complete reporting and international consensus over core outcome sets. Three national trials have now been funded as a result of this work. Two international initiatives to establish how best to measure the core outcome domains for eczema and vitiligo are ongoing.Trial registrationCurrent Controlled Trials Barrier Enhancement for Eczema Prevention (BEEP) (ISRCTN84854178 and NCT01142999), Study of Treatments fOr Pyoderma GAngrenosum Patients (STOP GAP) (ISRCTN35898459) and Hand Held NB-UVB for Early or Focal Vitiligo at Home (HI-Light Pilot Trial) (NCT01478945).FundingThis project was funded by the National Institute for Health Research (NIHR) Programme Grants for Applied Research programme and will be published in full inProgramme Grants for Applied Research; Vol. 4, No. 18.

Systematic review of published trials: long-term safety of topical corticosteroids and topical calcineurin inhibitors in pediatric patients with atopic dermatitis. BMC Pediatr 2016; 16:75. [PMID: 27267134 PMCID: PMC4895880 DOI: 10.1186/s12887-016-0607-9] [Citation(s) in RCA: 111] [Impact Index Per Article: 13.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/06/2015] [Accepted: 05/13/2016] [Indexed: 01/24/2023] Open
Abstract
BACKGROUND Many clinicians have concerns about the safety of atopic dermatitis (AD) treatments, particularly in children requiring long-term daily maintenance therapy. Topical corticosteroids (TCS) have been widely used for >5 decades. Long-term TCS monotherapy has been associated with adverse cutaneous effects including atrophy, rebound flares, and increased percutaneous absorption with potential for adverse systemic effects. Topical calcineurin inhibitors (TCIs), tacrolimus and pimecrolimus, available for 1-2 decades, are not associated with atrophy or increased percutaneous absorption after prolonged use and have much lower potential for systemic effects. However, since 2006 TCIs have carried a controversial Boxed Warning based on a theoretical risk of malignancy (eg, skin and lymphoma) that has limited TCI use for standard-of-care maintenance therapy. METHODS A comparative systematic search of PubMed was done for long-term (≥12 week) clinical trials of TCS or TCI treatment in patients <12 years with AD. Citations were reviewed for inclusion based on MeSH terms, abstracts, and relevant article text. Studies were excluded if they did not encompass subjects <12 years, or were <12 weeks' duration, retrospective, meta-analyses, or limited to anecdotal case reports. RESULTS Of 27 trials meeting criteria, 21 included 5825 pediatric patients treated with TCIs, and 6 included 1999 patients treated with TCS. TCS studies were limited to low- to mid-potency products, and all but one study lacked a vehicle control. Eight TCI studies were vehicle-controlled, and safety data were well reported, with ≤5 % of patients reporting discontinuation due to adverse effects (DAEs). Cutaneous and systemic adverse events (AEs) were similar in TCI and vehicle groups, with no reports of lymphoma. Safety data in TCS trials were less well reported. DAE incidence was addressed in just 2 trials, and systemic and cutaneous AEs were mostly unreported. CONCLUSIONS Data supporting long-term use of TCIs are robust, documenting safety and efficacy, while data supporting long-term TCS use are limited to low- to mid-potency products. Our review identifies a lack of information on the safety of commonly prescribed, long-term monotherapy with mid- to high-potency TCS in pediatric AD, and supports standard-of-care maintenance therapy with TCIs and intermittent use of low- to mid-potency TCS for flares.

Abstract
BACKGROUND Topical calcineurin inhibitors (TCIs) are widely used as an alternative to topical corticosteroids (TCSs) in treating of atopic dermatitis, but their risk versus benefit compared with TCSs remains unclear. OBJECTIVE We performed a systematic review of the efficacy, safety, and cost-effectiveness of TCI compared with TCS and emollients. METHODS Published meta-analysis, systematic reviews, and individual studies from January 2005 to January 2015 on the comparative efficacy, safety, and cost-effectiveness of TCI against emollients and TCS were included. RESULTS Tacrolimus is comparable to TCS in efficacy, safety profile, and cost-effectiveness. Pimecrolimus has a similar safety profile compared with TCS, emollients, and tacrolimus. It is superior to emollients but inferior to TCS and tacrolimus in efficacy and cost-effectiveness. The association of tacrolimus with malignancy remains uncertain. CONCLUSIONS Tacrolimus is an efficacious and cost-effective alternative to TCS, but its benefits need to be weighed against its still uncertain risk for malignancy. Pimecrolimus is appropriate for mild atopic dermatitis when TCS or tacrolimus is unsuitable.

Abstract
OBJECTIVE Using a network meta-analysis, we aimed to compare the efficacy and safety of tacrolimus and pimecrolimus as treatment options for children with atopic dermatitis (AD). METHODS Randomized controlled studies with a modified Jadad score >3 using tacrolimus or pimecrolimus in pediatric patients with AD were studied. RESULTS Out of 163 articles, 19 studies enrolling a total of 6,413 pediatric patients were selected. Pooled analysis revealed that tacrolimus 0.03% or 0.1% and pimecrolimus 1% were better at reducing eczema compared with vehicles. No significance was found between tacrolimus and pimecrolimus in improving the severity of eczema. More patients tended to withdraw in the vehicle groups compared to the tacrolimus and pimecrolimus groups. No significant difference existed between total adverse events and withdrawals in the tacrolimus and pimecrolimus groups. CONCLUSIONS Pimecrolimus was similar to tacrolimus in both efficacy and safety for AD in children, but both were better than vehicles.

Abstract
Background Eczema (syn. Atopic Eczema or Atopic Dermatitis) is a chronic, relapsing, itchy skin condition which probably results from a combination of genetic and environmental factors. The Global Resource of EczemA Trials (GREAT) is a collection of records of randomised controlled trials (RCTs) for eczema treatment produced from a highly sensitive search of six reference databases. We sought to assess the sensitivity of the GREAT database as a tool to save future researchers repeating extensive bibliographic searches. Methods All Cochrane systematic review on treatments for eczema and five non-Cochrane systematic reviews on eczema were identified as a reference set to assess the utility of the GREAT database in identifying randomised controlled trials (RCTs). RCTs included in the systematic reviews were checked for inclusion in the GREAT database by two independent authors. A third author resolved any disagreements. Results Five Cochrane and six non-Cochrane systematic reviews containing a total of 105 RCTs of eczema treatments were included. Of these, 95 fitted the inclusion criteria for the GREAT database and 88 were published from 2000 onwards. Of the 88 eligible studies, 92% were found in the GREAT database. Seven trials were not included in the GREAT database - two of these were reported within a review paper and one as an abstract with no trial results. Conclusions The sensitivity of the GREAT database for trials from 2000 onwards was high (75/88 trials, 94%). Sensitivity for the period prior to 2000 was less sensitive, due to differences in how the trials were identified prior to this time. ‘Dual’ filtering for new records has recently become part of the GREAT database methodology and should further improve the sensitivity of the database in time. The GREAT database can be considered as a primary source for future systematic reviews including randomised controlled trials of eczema treatments, but searches should be supplemented by checking reference lists for eligible trials, searching trial registries and contacting pharmaceutical companies for unpublished studies.

Abstract
Objective To evaluate the efficacy and safety of pimecrolimus cream 1% in the treatment of AD in the pediatric population. Methods PubMed, EMBASE, Web of Science and Cochrane library databases were searched till July 2013. The randomized and nonrandomized blinded studies of pimecrolimus cream 1% applied twice daily with Jaded score ≥3 in pediatric patients with AD were included. The efficacy outcomes included investigator global assessment (IGA), eczema area and severity index (EASI) scores, pruritus and care giver's assessments and flares free period. Adverse events were reviewed to assess the safety. Results Out of 81 studies, 7 were selected that enrolled 2,170 pediatric patients. The pooled analysis reported that pimecrolimus was no better to vehicle reducing eczema at day-8, day-26 and six weeks (OR 4.95, 95% CI 2.79–8.80), (OR 9.69, 95% CI 4.12–22.83) and (OR 3.83. 95% CI 1.94–7.56), respectively in children. Similarly, pimecrolimus did not show beneficial effects when analyzed for mild or absent pruritus at day 4 (OR 8.29, 95% CI 3.88–17.72 favoring vehicle), day 43 (OR 1.81 95% CI 1.13–2.89 favoring vehicle) and 1 week (OR 2.29, 95%CI 1.45 to 3.60 favoring vehicle) as compared with vehicle. One study comparing pimecrolimus with tacrolimus found no significant difference in achieving mild or absent pruritus (OR 0.94, 95% CI 0.44–1.99). More patients showed an improvement in overall disease in vehicle group at day 8 (OR 3.30, 95% CI 2.03–5.35), day 29 (OR 14.14, 95% CI 6.87–29.13) and day 43 (OR 4.11, 95% CI 2.59–6.52) as compared with pimecrolimus 1% group, as assessed by caregivers. No significant difference was seen between the total AEs in both groups (pimecrolimus vs vehicle/tacrolimus) (OR 1.19, 95% CI 0.85, 1.65) Conclusion The results of the present meta-analysis showed that pimecrolimus cream 1% was not significantly better to vehicle for AD in pediatrics population.

Abstract
Topical calcineurin inhibitors (TCIs), commercially available since 2000–2001, are the first and only topical medications approved for chronic treatment of atopic dermatitis (AD) in pediatric patients and remain a welcomed alternative to topical corticosteroids. In January 2006, the US Food and Drug Administration (FDA) issued a boxed warning requirement based on a theoretical risk of malignancy (including lymphoma) with TCI use. However, in the years since, analyses of epidemiologic and clinical data have failed to demonstrate a causal relationship between TCI use and malignancy or lymphoma risk, especially for pimecrolimus cream. In fact, the observed number of malignancies and lymphomas observed both in post-marketing surveillance and reported to the FDA using its adverse events reporting system is much lower among TCI-exposed patients than the expected number for the general population. Furthermore, among children enrolled in post-marketing pediatric registry studies for both tacrolimus and pimecrolimus followed for up to 5.5 years [10,724 patient-years (PY)] or 6.5 years (16,219 PY), respectively, the observed number of malignancies and lymphomas is very low and similar to the number expected for a sample of similar size in the general population. In addition to reporting these comparative malignancy and lymphoma data, this article provides a historical overview of the boxed warning requirement and critically evaluates the preclinical, clinical, and epidemiological evidence that has thus far failed to substantiate a relationship between TCI use and malignancy. The authors also provide practical clinical advice for optimizing AD management and patient care in the context of the boxed warning.

Abstract
BACKGROUND A number of disease-severity and quality-of-life (QoL) instruments have emerged in atopic dermatitis (AD) in the last decade. OBJECTIVES To identify trends in outcomes instruments used in AD clinical trials and to provide a useful summary of the dimensions and validation studies for the most commonly used measures. METHOD All randomized control trials (RCTs) from 1985 to 2010 in the treatment of AD were examined. RESULTS Among the 791 RCTs reviewed, we identified 20 disease-severity and 14 QoL instruments. Of these outcomes instruments, few have been validated. SCORAD, EASI, IGA and SASSAD were the most commonly used disease-severity instruments and CDLQI, DFI, DLQI and IDQOL were the most frequently used QoL measures. LIMITATIONS The small number of RCTs using QoL scales makes identifying trends for QoL instruments difficult. CONCLUSION Overall, there is an increase in the use of disease-severity and QoL instruments in AD clinical trials.

Abstract
Topical pimecrolimus 1% cream (Elidel) [hereafter referred to as topical pimecrolimus] is a nonsteroidal alternative in the treatment of pediatric atopic dermatitis. In vehicle-controlled, short-term, continuous-use trials in pediatric patients with mild to moderate atopic dermatitis, topical pimecrolimus was effective in treating disease symptoms. Topical pimecrolimus was effective in preventing disease flares and reducing the need for topical corticosteroids in longer term, intermittent-use trials. In addition, topical pimecrolimus was associated with improvements in the health-related quality of life of pediatric patients with atopic dermatitis and their parents. In vehicle-controlled trials, topical pimecrolimus was generally as well tolerated as vehicle. Topical pimecrolimus showed similar efficacy to topical tacrolimus 0.03% ointment in a short-term, continuous-use trial and the two agents had a generally similar tolerability profile. Although comparative data between topical pimecrolimus and topical corticosteroids are lacking in pediatric patients, and the long-term tolerability (beyond 1-2 years) of topical pimecrolimus is yet to be established, topical pimecrolimus is a useful agent in the management of pediatric patients with mild to moderate atopic dermatitis who do not achieve satisfactory treatment with other topical pharmacologic treatments, including topical corticosteroids.

Topical pimecrolimus 1% cream (Elidel) [hereafter referred to as topical pimecrolimus] is a nonsteroidal alternative in the treatment of pediatric atopic dermatitis. In vehicle-controlled, short-term, continuous-use trials in pediatric patients with mild to moderate atopic dermatitis, topical pimecrolimus was effective in treating disease symptoms. Topical pimecrolimus was effective in preventing disease flares and reducing the need for topical corticosteroids in longer term, intermittent-use trials. In addition, topical pimecrolimus was associated with improvements in the health-related quality of life (HR-QOL) of pediatric patients with atopic dermatitis and their parents. In vehicle-controlled trials, topical pimecrolimus was generally as well tolerated as vehicle. Topical pimecrolimus showed similar efficacy to topical tacrolimus 0.03% ointment (hereafter topical tacrolimus) in a short-term, continuous-use trial and the two agents had a generally similar tolerability profile. Although comparative data between topical pimecrolimus and topical corticosteroids are lacking in pediatric patients, and the long-term tolerability (beyond 1-2 years) of topical pimecrolimus is yet to be established, topical pimecrolimus is a useful agent in the management of pediatric patients with mild to moderate atopic dermatitis who do not achieve satisfactory treatment with other topical pharmacologic treatments, including topical corticosteroids.

Abstract
The aim of this study is to compare twice-daily and once-daily applications of pimecrolimus cream 1% for prevention of atopic dermatitis relapses in pediatric patients. This multicenter trial enrolled 300 outpatients aged 2 to 17 years, with mild-to-severe atopic dermatitis. The patients were initially treated with twice-daily topical pimecrolimus until complete clearance or for up to 6 weeks (open-label period). Those who achieved a decrease of at least 1 point in the Investigator's Global Assessment score were then randomized to double-blind treatment with pimecrolimus cream 1% either twice daily or once daily for up to 16 weeks. Study medication was discontinued during periods of disease remission (Investigator's Global Assessment = 0). The primary efficacy end point of the double-blind phase was disease relapse (worsening requiring topical corticosteroids or additional/alternative therapy and confirmed by Investigator's Global Assessment score > or = 3 and pruritus score > or = 2). Of the 300 patients enrolled in the study, 268 were randomized to treatment with pimecrolimus cream 1% either twice daily or once daily (n = 134 in each group). The relapse rate was lower in the twice-daily dose group (9.9%) than that in the once-daily dose group (14.7%), but analysis of the time to disease relapse, using a Cox proportional model to adjust for confounding variables, did not show a statistically significant difference between treatment arms (hazard ratio: 0.64; 95% CI: 0.31-1.30). Treatment of active atopic dermatitis lesions with pimecrolimus cream 1% twice daily, followed by the once-daily dosing regimen, was sufficient to prevent subsequent atopic dermatitis relapses over 16 weeks in pediatric patients.

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. J Am Acad Dermatol 2008; 58:990-9. [PMID: 18359127 DOI: 10.1016/j.jaad.2008.02.008] [Citation(s) in RCA: 71] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2007] [Revised: 01/22/2008] [Accepted: 02/12/2008] [Indexed: 11/20/2022]
Abstract
BACKGROUND Intermittent dosing of a topical calcineurin inhibitor for preventing atopic dermatitis (AD) disease relapse in patients with stabilized AD has not been evaluated. OBJECTIVE We sought to evaluate the long-term efficacy and safety of 3-times-weekly use of tacrolimus ointment in preventing AD disease relapse. METHODS 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. RESULTS 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). LIMITATIONS 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. CONCLUSIONS 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.

Abstract
Atopic dermatitis (AD) is a common disease in children. Despite good skin care and trigger avoidance, many children with AD require pharmacologic treatment to manage their disease. In recent years, topical calcineurin inhibitors (TCIs) have been used as an alternative to topical corticosteroids to treat some children with AD. However, revisions to the US labeling for TCIs (i.e. a boxed warning and a medication guide) have generated concern among pediatricians regarding TCI safety and raised questions about the appropriate use of TCIs in the pediatric population. Data from several well designed studies support the efficacy of TCIs in the treatment of AD. Safety concerns arise from a small number of reported malignancies, animal toxicology studies, and the potential adverse effects (including immunosuppression and risk of lymphoma) observed in patients who received systemically administered calcineurin inhibitors for suppression of solid-organ transplant rejection. Several factors indicate that these effects do not occur with topical administration: (i) systemic levels following topical administration are at least 10-fold lower than with oral administration; (ii) the small number of lymphomas reported to date in persons exposed to TCI use are not consistent with the types seen in transplant patients or other immunosuppressed patients; and (iii) no adverse effects on the immune system (as assessed by measures including vaccination response and skin delayed-type hypersensitivity reaction) have been observed in clinical trials of TCIs in children with AD. Overall, TCIs have an established safety and efficacy profile as long-term maintenance therapy in children with AD.

Abstract
BACKGROUND Pimecrolimus was developed as an alternative to topical corticosteroids for treating eczema (atopic dermatitis) but its efficacy and safety compared with existing treatments remains unclear. OBJECTIVES To assess the effects of topical pimecrolimus for treating eczema. SEARCH STRATEGY We searched the Cochrane Skin Group Specialised Register (to October 2006), the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 3, 2006), MEDLINE (from 2003 to October 2006), and EMBASE (from 2005 to October 2006). We also contacted researchers and manufacturers in the field. SELECTION CRITERIA Randomised controlled trials of 1.0% topical pimecrolimus used twice daily compared against other topical comparators for treating eczema. DATA COLLECTION AND ANALYSIS Two authors independently examined each retrieved study for eligibility and extracted data for efficacy, tolerability and safety. A random-effects model was used to estimate the pooled risk ratios (RRs) and 95% confidence intervals (95% CIs). MAIN RESULTS We included 31 trials (8019 participants) in the analysis. In short-term (</= 6 weeks) trials, pimecrolimus cream was significantly more effective and well-tolerated than vehicle (cream base, but not containing pimecrolimus). In long-term trials (>/=6 months), pimecrolimus was significantly better than vehicle in preventing flares (9 trials, 3091 participants, RR 1.47, 95% CI 1.32 to 1.64 at six months) and in improving quality of life. Pimecrolimus was significantly less effective than two topical corticosteroids, i.e. 0.1% triamcinolone acetonide for investigators' global assessment (1 trial, 658 participants, RR 0.75, 95% CI 0.67 to 0.83) and 0.1% betamethasone valerate for participants' global assessment (1 trial, 87 participants, RR 0.61, 95% CI 0.45 to 0.81) at three weeks. Pimecrolimus was also associated with significantly more overall withdrawals and skin burning. None of the trials reported on key adverse effects such as thinning of skin. Pimecrolimus was significantly less effective than 0.1% tacrolimus for investigators' global assessment at six weeks (RR 0.58, 95% CI 0.46 to 0.74) and led to more withdrawals due to lack of efficacy (RR 2.37, 95% CI 1.10 to 5.08) based on two trials involving 639 participants, but there was no significant difference in proportions of participants experiencing any adverse events. AUTHORS' CONCLUSIONS Topical pimecrolimus is less effective than moderate and potent corticosteroids and 0.1% tacrolimus. The therapeutic role of topical pimecrolimus is uncertain due to the absence of key comparisons with mild corticosteroids.
