Topical corticosteroid phobia in patients with atopic eczema

Atopic dermatitis treatment: A comprehensive review of conventional and novel bioengineered approaches

Atopic dermatitis (AD) remains a challenging condition, with conventional treatments often leading to adverse effects and limited efficacy. This review explores the diverse landscape of AD treatments, encompassing conventional methods, novel topical and systemic therapies, and emerging bioengineered strategies. While conventional drug administration often requires high dosages or frequent administration, leading to adverse effects, targeted biologics have shown promise. Phototherapy and wet wrap therapy, while helpful, have limitations. Given these factors, the need for modern and effective therapeutic strategies for AD is pressing. Complementary or alternative therapies have garnered significant attention in recent years as a compelling treatment for AD. Among these, functionalized biomaterials and textiles with physicochemical, nanotechnology-based characteristics, or bioengineered features are some of the most common typical adjuvant therapies. The multifunctional-engineered biomaterials, as a new generation of biomedical materials, and stem cells, seem to hold tremendous promise for the treatment of dermatological diseases like AD. Biomaterials have seen great success, especially in various medical fields, due to their unique and adaptable characteristics. These materials, including collagen, PCL, and PLGA, offer unique advantages, such as biocompatibility, biodegradability, controlled drug release, and enhanced drug retention.

Utilization and related harms of systemic glucocorticosteroids for atopic dermatitis: claims data analysis

BACKGROUND

Systemic glucocorticosteroids (SGCs) are used in the short-term treatment of atopic dermatitis (AD), but are not recommended for long-term use because they are associated with severe side-effects.

OBJECTIVES

This study aimed to characterize the utilization and potentially negative effects of SGC use for AD in German statutory health insurance (SHI) claims data.

METHODS

Cross-sectional and longitudinal analysis of a large nationwide SHI dataset. SGC drug prescriptions and incidences of predefined comorbidities after drug initiation that were known to be potentially harmful side-effects were analysed. SGC use was quantified by (-definition 1) the number of quarters with at least one SGC prescription and (definition 2) the defined daily doses (DDD). Comparisons were adjusted for age, sex and morbidity.

RESULTS

The AD prevalence was 4.07% in 2020 (4.12% women, 3.42% men). During this period 9.91% of people with AD were prescribed SGCs compared with 5.54% in people without AD (P < 0.01). Prescribing of SGCs was significantly higher in women (10.20% vs. 9.42% in men, P < 0.01) and in the elderly. AD and SGC prevalence varied regionally. In a 3-year follow-up period, 58% of people with AD receiving a SGC were prescribed SGCs in > one quarter and 15% in > six quarters. The odds of developing osteoporosis [odds ratio (OR) 3.90 -(definition 1) and 1.80 (definition 2)] and diabetes [OR 1.90 (definition 1) and 1.38 (definition 2)] were significantly higher in people with AD on SGCs, especially in the frequently prescribed group compared with the rarely prescribed group, regardless of quantified use.

CONCLUSIONS

A considerable number of people with AD in Germany are prescribed long-term SGCs. The onset of medical conditions known to be harmful effects of steroids was significantly more frequent in those who were frequently prescribed SGCs, indicating the need for optimized healthcare.

Management of Moderate-to-Severe Atopic Dermatitis in Adults: A Cross-Sectional Survey of Dermatologists Within the Asia-Pacific Region

INTRODUCTION

Limited evidence is available on real-world management of atopic dermatitis (AD) among Asian adults. This cross-sectional study aimed to assess current approaches in AD diagnosis and management in Asia.

METHODS

Practising dermatologists regularly treating patients with moderate-to-severe AD were recruited from eight Asia-Pacific territories, namely Mainland China, Hong Kong, India, Japan, Singapore, South Korea, Taiwan, and Thailand. A survey was administered to eligible dermatologists after screening and taking informed consent. Data from fully completed submissions were analysed using descriptive statistics. The study was reviewed by the institutional review board in each territory.

RESULTS

Data from 271 dermatologists were included for analysis. About one-third (31.7%) reported that they referred to the Hanifin and Rajka criteria during diagnosis. The majority of dermatologists used clinical impression when assessing AD severity and treatment response. Reduction of eczema and pruritus was the primary treatment objective when managing both acute (98.1%) and chronic (69.1%) AD. More than half of dermatologists preferred adding systemic anti-inflammatory medication for patients who did not respond to maximized topical treatment, while 43.6% would switch to another systemic medication for those failing to respond to maximized systemic treatment. Topical corticosteroids were frequently selected by dermatologists. For systemic therapies, oral corticosteroids were most frequently used, followed by cyclosporin and dupilumab. Narrow-band ultraviolet B was the most common phototherapy reported (84.9%). There was considerable variation in estimated average and maximum durations of therapies used to treat AD.

CONCLUSION

This study has provided insights on the real-world management of moderate-to-severe AD in the Asia-Pacific region. The diverse approaches in diagnosis and treatment highlight the multifactorial nature of AD, reliance on clinical judgement, and importance of personalized care. To improve outcomes in patients with AD, it will be crucial to develop biomarkers for diagnosis, reduce subjectivity in assessment, as well as promote access to newer and effective therapies.

Prevalence and clinical impact of topical corticosteroid phobia among patients with chronic hand eczema-Findings from the Danish Skin Cohort

BACKGROUND

Topical corticosteroid phobia (TOPICOP) is associated with poor treatment adherence and is common among patients with skin disease. Knowledge about corticosteroid phobia and treatment adherence among patients with chronic hand eczema (CHE) is limited.

OBJECTIVES

To investigate patient-reported outcomes regarding topical corticosteroids (TCSs), and their impact on treatment adherence in patients with CHE.

METHODS

Patients with CHE from the Danish Skin Cohort answered a questionnaire including the TOPICOP scale and Medication Adherence Report Scale. Response rate was 69.2%.

RESULTS

Of 927 with CHE, 75.5% totally or almost agreed that TCS damage the skin, 48.9% totally or almost agreed that TCS would affect their future health and 36.3% reported some degree of fear of TCS although they were unaware of any TCS-associated risks. Most patients (77.9%) always or often stop treatment as soon as possible, whereas 54.8% always or often wait as long as possible before starting treatment. Overall, 38.8% reported that they had taken less medicine than prescribed and 54.0% had stopped treatment throughout a period. Treatment adherence decreased with increasing corticosteroid phobia (P = .004).

LIMITATIONS

TOPICOP has not been validated in patients with CHE.

CONCLUSIONS

Corticosteroid phobia is common among patients with CHE and negatively associated with treatment adherence.

Topically Applied Therapies for the Treatment of Skin Disease: Past, Present, and Future

The purpose of this review is to summarize essential biological, pharmaceutical, and clinical aspects in the field of topically applied medicines that may help scientists when trying to develop new topical medicines. After a brief history of topical drug delivery, a review of the structure and function of the skin and routes of drug absorption and their limitations is provided. The most prevalent diseases and current topical treatment approaches are then detailed, the organization of which reflects the key disease categories of autoimmune and inflammatory diseases, microbial infections, skin cancers, and genetic skin diseases. The complexity of topical product development through to large-scale manufacturing along with recommended risk mitigation approaches are then highlighted. As such topical treatments are applied externally, patient preferences along with the challenges they invoke are then described, and finally the future of this field of drug delivery is discussed, with an emphasis on areas that are more likely to yield significant improvements over the topical medicines in current use or would expand the range of medicines and diseases treatable by this route of administration. SIGNIFICANCE STATEMENT: This review of the key aspects of the skin and its associated diseases and current treatments along with the intricacies of topical formulation development should be helpful in making judicious decisions about the development of new or improved topical medicines. These aspects include the choices of the active ingredients, formulations, the target patient population's preferences, limitations, and the future with regard to new skin diseases and topical medicine approaches.

Topical anti-inflammatory treatments for eczema: network meta-analysis

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.

Insight into Current Practices of Community Pharmacists in Topical Corticosteroid Prescribing and Counseling: Cross-Sectional Survey Study from Saudi Arabia

BACKGROUND

Topical corticosteroids are commonly used to treat several skin conditions, most notably atopic dermatitis. Many studies have found that patients lack knowledge about the safety, potency, and appropriate use of topical corticosteroids. This can be due to ineffective education by pharmacists and other healthcare providers. This study aims to evaluate the appropriateness of dispensing and counseling practices of community pharmacists towards topical corticosteroids in Saudi Arabia.

METHODS

A cross-sectional survey study was conducted in Saudi Arabia among 418 community pharmacists from different regions of Saudi Arabia. Data were collected using a validated questionnaire that covered community pharmacists' sociodemographic information, their perceptions of patient knowledge about topical corticosteroid use, and their dispensing and their counseling practices, in addition to their perceived barriers to counseling.

RESULTS

The majority of the participating community pharmacists were Saudi (57.4%), female (66.7%), holding a bachelor's degree (63.4%), and full-time workers (91.1%). Most of the time, community pharmacists counseled patients on the frequency of application per day and the duration of treatment (75.8% and 74.8%, respectively). The median counseling practice score was 17, with an IQR of 14-21. The main barrier to counseling was lack of time (33.7%). Only 15% of community pharmacists accurately identified all scenarios that necessitate medical referrals. Dry skin, itchiness, and irritation were the most common side effects reported by community pharmacists for patients to complain about (69.4%). Most pharmacists agreed that misuse is the most likely cause of topical corticosteroid adverse drug events (53.7%), followed by medication overuse, such as patient self-treatment (48%).

CONCLUSION

Community pharmacists counseling practices to their patients about the use of topical corticosteroids require improvement. Continuing education and hands-on training are needed for community pharmacists regarding counseling about topical corticosteroids use.

Tacrolimus-loaded chitosan-based nanoparticles as an efficient topical therapeutic for the effective treatment of atopic dermatitis symptoms

Atopic dermatitis (AD) is a chronic cutaneous disease with a complex underlying mechanism, and it cannot be completely cured. Thus, most treatment strategies for AD aim at relieving the symptoms. Although corticosteroids are topically applied to alleviate AD, adverse side effects frequently lead to the withdrawal of AD therapy. Tacrolimus (TAC), a calcineurin inhibitor, has been used to treat AD, but its high molecular weight and insolubility in water hinder its skin permeability. Herein, we developed and optimized TAC-loaded chitosan-based nanoparticles (TAC@CNPs) to improve the skin permeability of TAC by breaking the tight junctions in the skin. The prepared nanoparticles were highly loadable and efficient and exhibited appropriate characteristics for percutaneous drug delivery. TAC@CNP was stable for 4 weeks under physiological conditions. CNP released TAC in a controlled manner, with enhanced skin penetration observed. In vitro experiments showed that CNP was non-toxic to keratinocyte (HaCaT) cells, and TAC@CNP dispersed in an aqueous solution was as anti-proliferative as TAC solubilized in a good organic solvent. Importantly, an in vivo AD mouse model revealed that topical TAC@CNP containing ~1/10 of the dose of TAC found in commercially used Protopic® Ointment exhibited similar anti-inflammatory activity to that of the commercial product. TAC@CNP represents a potential therapeutic strategy for the management of AD.

Linguistic Validation and Reliability of the Croatian Version of the TOPICOP Questionnaire

Background and Objectives: This study demonstrates the factor structure and reliability of the Croatian version of the TOPICOP (Topical Corticosteroid Phobia) questionnaire, thereby contributing to further validation and standardization of the measurement of topical corticophobia with dermatological patients or their parents, which directly affects patient or parent compliance, as well as the final therapeutic effect. Materials and Methods: The cross-sectional, observational study was conducted at the University Hospital Centre Split, Department of Dermatovenerology. The research involved inviting 120 participants (age 12-68) who attended the University Hospital Centre Split's Atopy School, patients examined in the Dermatology Outpatient Clinic of the University Hospital Centre Split and diagnosed with atopic dermatitis (AD) or allergic contact dermatitis (ACD), and parents or legal representatives of patients younger than 12 years old. The TOPICOP questionnaire consists of 12 items assessing the three different components of topical corticophobia (worries, beliefs, and behaviour). Respondents evaluated their perception of the correctness of each statement within 10 min of filling out the questionnaire on a four-point Likert scale. Results: The response rate was 94%, resulting in a sample of 113 respondents (109 adults and 4 children). Factor analysis yielded one common factor of relatively high reliability (Cronbach α = 0.85, 95% CI 0.81 to 0.89). No differences were found in questionnaire scores between male and female participants, nor between the parents/legal representatives of dermatological patients and other patients. Conclusions: This research contributes to further development of the appropriate measuring instrument, its practical application, and thus, the better recognition, resolution, and prevention of topical corticophobia as part of the better overall healthcare and treatment of chronic dermatological patients.

Topical Corticosteroid Phobia among Danish Pharmacy Staff

INTRODUCTION

Topical corticosteroid (TCS) phobia may negatively impact treatment adherence. Currently, there are few studies exploring trust and knowledge of TCS use among pharmacy staff. The objective of this work was to examine TCS knowledge and possible phobia among Danish pharmacy staff.

METHODS

A questionnaire, based on Topical Corticosteroid Phobia (TOPICOP©) questionnaire, was developed and rephrased to fit pharmacy staff. The questions were Likert scales and numerical rating scales (NRS) (0-10). In October/November 2021, 64 pharmacies were invited. If the pharmacies agreed to participate, a researcher visited the pharmacies and distributed the questionnaires.

RESULTS

A total of 244 pharmacy workers from 59 pharmacies participated. The majority (95.4%) responded that they were aware of side effects of TCS; however, misconceptions regarding side effects were found in up to 34% of participants. Regarding TCS use, 40% sometimes advised the patients to wait as long as possible before initiating treatment with TCS. Confidence in dispensing TCS to patients was high, with a mean of 8.45 (NRS).

CONCLUSION

Danish pharmacy staff generally reported high confidence in TCS use. Misconceptions regarding side effects were common, and there was a tendency to giving advices on TCS treatment that may indicate low confidence in TCS. Thorough education of pharmacy staff is needed to improve the knowledge of TCS.

Atopic Dermatitis in Children

Atopic dermatitis (AD) is extremely common in the pediatric population, and most children with AD will first present to their primary care provider (PCP). The PCP can recognize AD by its clinical features, including itch, a chronic relapsing course, and the characteristic eruption. The cornerstone of AD therapy is dry skin care, typically a short daily bath/shower followed by an emollient applied to all skin. Most children with AD will also require topical medications, such as topical corticosteroids and/or topical nonsteroidal therapies. For children with more severe disease, systemic agents, including several novel therapies, may be required. In managing AD, the clinician must monitor for side effects of medications as well as complications of the AD itself, the most common of which is secondary infection. An understanding of the pathogenesis, treatments, and complications of AD is essential for the PCP, as untreated (or undertreated) AD has a significant impact on the quality of life of affected children and their caregivers.

5α-Tetrahydrocorticosterone: A topical anti-inflammatory glucocorticoid with an improved therapeutic index in a murine model of dermatitis

BACKGROUND AND PURPOSE

Glucocorticoids are powerful anti-inflammatory drugs, but are associated with many side-effects. Topical application in atopic dermatitis leads to skin thinning, metabolic changes, and adrenal suppression. 5α-Tetrahydrocorticosterone (5αTHB) is a potential selective anti-inflammatory with reduced metabolic effects. Here, the efficacy and side-effect profile of 5αTHB were compared with hydrocortisone in preclinical models of irritant dermatitis.

EXPERIMENTAL APPROACH

Acute irritant dermatitis was invoked in ear skin of male C57BL/6 mice with a single topical application of croton oil. Inflammation was assessed as oedema via ear weight following treatment with 5αTHB and hydrocortisone. Side-effects of 5αTHB and hydrocortisone were assessed following chronic topical steroid treatment (28 days) to non-irritated skin. Skin thinning was quantified longitudinally by caliper measurements and summarily by qPCR for transcripts for genes involved in extracellular matrix homeostasis; systemic effects of topical steroid administration also were assessed. Clearance of 5αTHB and hydrocortisone were measured following intravenous and oral administration.

KEY RESULTS

5αTHB suppressed ear swelling in mice, with ED50 similar to hydrocortisone (23 μg vs. 13 μg). Chronic application of 5αTHB did not cause skin thinning, adrenal atrophy, weight loss, thymic involution, or raised insulin levels, all of which were observed with topical hydrocortisone. Transcripts for genes involved in collagen synthesis and stability were adversely affected by all doses of hydrocortisone, but only by the highest dose of 5αTHB (8× ED50 ). 5αTHB was rapidly cleared from the systemic circulation.

CONCLUSIONS AND IMPLICATIONS

Topical 5αTHB has potential to treat inflammatory skin conditions, particularly in areas of delicate skin.

Topical Corticosteroid Phobia Among Women Affected With Vulvar Lichen Sclerosus: Results From a Cross-sectional Survey

OBJECTIVE

Topical corticosteroid (TC) phobia (TCP) is common in subjects affected with chronic inflammatory skin diseases who need prolonged corticosteroid treatments. The aim of this study was to assess TCP in women affected with vulvar lichen sclerosus (VLS).

MATERIALS AND METHODS

This observational, cross-sectional study included adult patients with VLS who either started or were undergoing a TC treatment at our vulva unit between May 2022 and May 2023. All patients completed the self-administered TOPICOP questionnaire, which is validated for measuring concerns, worries, and beliefs about TC use. The scores obtained were analyzed in relation to demographic, history, and clinical data.

RESULTS

The majority of the 165 (92.1%, 66.5 ± 11.9 years) included patients who had previously undergone TC treatments, mostly for VLS; 81.8% of them had received information about TCs, mainly from dermatologists (86.7%). The median global TOPICOP score was 16.7% (interquartile range. 8.3-30.6), corresponding to a raw median value of 6.0 (interquartile range, 3.0-11.0). The median subscores for the 2 TOPICOP domains, namely, mistaken beliefs and worries about TCs, were equal to each other. At multivariate analysis, none of the collected variables showed a significant association with the degree of TCP.

CONCLUSIONS

In our VLS patients, TCP resulted rather low, probably because of the small skin area being treated and the high percentage of women who had already used TCs and who had received information about them from a dermatologist. This latter point suggests that adequate counseling could be a strong basis for greater awareness and serenity in the long-term use of TCs.

Do people with eczema and their carers understand topical steroid potency? Results of two surveys

Topical corticosteroids (TCSs) are classified into four potencies: mild, moderate, potent and very potent. Confusion arises from the wide range of products available, none of which have the potency level printed on the tubes or packaging. An online survey of patients and carers of people with eczema showed that only 17% of 984 respondents knew how many potencies there are. In a second survey, 315 respondents provided 1520 assignments of the potency of commonly used TCSs: 55.5% were correct, 21% were underestimates and 23.5% overestimates. Some errors were extreme: 12 (8%) of those using a very potent TCS considered it mild while 9 (27%) using a mild TCS considered it potent or very potent. Other themes expressed in free-text comments included inadequate and conflicting advice about using TCSs and lack of warnings about long-term adverse effects, particularly topical steroid withdrawal. Ninety-five per cent of respondents wanted TCSs to be clearly labelled with potency.

Adherence in Atopic Dermatitis

Atopic dermatitis is a chronic dermatologic condition requiring extended treatment times with topical application of medications. While atopic dermatitis treatments can be highly effective when used as directed, oftentimes patients do not respond as expected, raising concern for nonadherence versus nonresponse. This chapter aims to describe what is currently known about adherence in atopic dermatitis and to discuss strategies to improve adherence in order to improve treatment outcomes. Whether intentional or unintentional, nonadherence to treatment can limit patient outcomes of this disease for a variety of reasons. These include frustration with medication efficacy, inconvenience, and fear of side effects. Other factors include forgetfulness, financial burden of treatment, lack of trust in the physician, dislike of prescribed medication, or lack of understanding of disease or treatment. Several interventions have been studied with the aim of improving adherence in atopic dermatitis-such as educational workshops for patients and caregivers, earlier follow-up visits, and text messages reminders-however, these are often limited by sample size and power. Further research is needed to study both specific patterns of nonadherence in atopic dermatitis, as well as methods to improve them.

Safety, efficacy, and pharmacokinetics of delgocitinib ointment in infants with atopic dermatitis: A phase 3, open-label, and long-term study

BACKGROUND

Delgocitinib ointment, a topical Janus kinase inhibitor, is used as treatment of patients with atopic dermatitis (AD) aged ≥2 years in Japan. Although initiating appropriate and early treatment upon the onset of AD in childhood is important, the safety and efficacy of delgocitinib ointment in infants with AD have not been established.

METHODS

This phase 3 study was conducted from October 2020 to June 2022 (number JapicCTI-205412). Eligible Japanese infants with AD aged 6 to <24 months received 0.25% or 0.5% of delgocitinib ointment twice daily for 52 weeks in an open-label uncontrolled manner. Topical corticosteroids were allowed to apply for worsening AD during the treatment period at the investigators' discretion.

RESULTS

A total of 22 infants were enrolled. Adverse events (AEs) were reported in 21 (95.5%) infants and were mostly mild. No treatment-related AEs were reported. The Modified Eczema Area and Severity Index (mEASI) score continuously decreased until week 4, and the score reduction was maintained until week 52. The mean percent changes in the mEASI score from baseline were -73.5% at week 4, -81.7% at week 28, and -81.9% at week 52. Delgocitinib was not detected in the plasma of most infants (68.2%-95.2%).

CONCLUSIONS

Delgocitinib ointment is well tolerated and effective for up to 52 weeks when applied to Japanese infants with AD.

Topical Corticosteroid Phobia Among Parents of Children with Atopic Dermatitis (Eczema)- A Cross-Sectional Study

Background

Anxiety about using topical corticosteroids (TCS) for childrens among parents and caretakers is a common cause of treatment failure and an overall decline in the child's quality of life. The purpose of this study was to examine the perspectives and worries of parents of Atopic dermatitis (AD) children regarding TCS. Additionally, we investigate the degree of phobia in relation to the use of the TCS.

Materials and Methods

A convenience sample of 301 parents of children who had been identified with atopic dermatitis from two hospitals in Taif city were enrolled in this study. Parents who chose to participate were sent a questionnaire measuring their level of fear of TCS using the TOPICOP© scale, which also included inquiries about their demographics and clinical characteristics. Multivariate analysis was used to determine what factors influence people's overall levels of fear.

Results

The median global TOPICOP score was 66.6% (IQR 60.4-75%), SD 12.83%, which showed that nearly two-thirds of the participants showed corticosteroid phobia. A multifactorial ANOVA model showed that parents who had a female child with AD and mothers who had experienced drug allergies had a significant influence on TOPICOP scores (P<0.05).

Conclusion

Topical corticosteroid phobia is widespread among parents of children patients with AD in Taif. Regarding the utilization of TCS, we place a strong emphasis on the significant role that physicians play as sources of reliable information and proper education.

Efficacy and Tolerability of a Novel Topical Treatment Containing Pea Protein and Xyloglucan in the Management of Atopic Dermatitis in Children: A Prospective, Multicenter Clinical Study

INTRODUCTION

Atopic dermatitis (AD) is a chronic disease that occurs mainly in children. Topical corticosteroids are the main treatment for mild to moderate AD, although they can induce side effects. The efficacy and tolerability of xyloglucan and pea protein (XG-PP) was compared with hydrocortisone in pediatric patients with AD as a steroid-sparing solution.

METHODS

A prospective, multicenter, comparative study enrolled 42 patients (age 0.5-12 years) with mild-to-moderate AD, assigned 1:1 to XG-PP or hydrocortisone ointment. Treatments were applied twice daily for 14 consecutive days and assessed at baseline, day 8, and day 15. Efficacy endpoints were AD Severity Index (ADSI) score, Scoring Atopic Dermatitis (SCORAD) index, and Patient-Oriented Eczema Measure (POEM). Tolerability was assessed by the occurrence of adverse events (AEs).

RESULTS

Both treatments significantly improved ADSI mean score from baseline to day 15; in the XG-PP arm, ADSI score decreased from 10.55 to 4.15 (p = 0.00001), and in the hydrocortisone arm, from 10.65 to 4.30 (p = 0.0001). In the XG-PP arm, the mean SCORAD score decreased from 65.86 to 30.26 (p = 0.00001) and in the hydrocortisone arm from 68.84 to 31.19 (p = 0.0001) at day 15. An overall decrease from moderate to mild AD for both arms (p = 0.0001) was observed with POEM. For all the three indexes evaluated, no statistical significant differences between the study arms evolution from baseline to day 8 or to day 15 were found. No AEs were reported.

CONCLUSION

XG-PP provided a comparable efficacy to hydrocortisone ointment in managing AD, thus representing a safe and effective steroid-sparing alternative in pediatric patients with AD.

Public Awareness Regarding Corticosteroid Use and Side Effects: A Cross-Sectional Study in Riyadh, Saudi Arabia

The administration of corticosteroids may have possible hazards, ranging from minor adverse medication reactions to more serious considerations. We aimed to assess levels of public awareness concerning corticosteroid use, side effects, and predictors of its use. A cross-sectional study was conducted online throughout the period of May to July 2023. The present investigation utilized a previously developed questionnaire tool. The study encompassed a cohort of 732 individuals. Upon inquiry regarding the adverse effects of corticosteroid treatment, the participants predominantly reported weight gain, skin alterations, and fluid retention leading to breathing difficulties, constituting 44.4%, 30.3%, and 27.7% of the responses, respectively. The prevailing adverse effects observed in individuals using corticosteroids were weight gain, alterations in mood, and changes in skin characteristics, which accounted for 38.1%, 25.7%, and 21.8% of reported cases, respectively. Individuals within the age range of 41-50 years and those who are currently not working show a higher propensity for utilizing corticosteroids in comparison to other demographic groups (p < 0.05). The level of general public knowledge about corticosteroids and the side effects connected with them in Saudi Arabia was adequate. Demographic factors, such as age, gender, and education, have an impact on the use of corticosteroids.

Hidden gems: a pilot project to solicit and reward patients' and caregivers' ideas for research

BACKGROUND

Patients and caregivers investigate a wide range of approaches to address the signs and symptoms of their condition. Such investigation could lead to new treatment insights or avenues for research. However, currently there are few channels through which patients and families can share the results of their personal experiences; they need a platform to share their insights with the research community.

METHODOLOGY

Two non-profit organizations, Global Parents for Eczema Research and the International Alliance of Dermatology Patient Organizations, developed a project to pioneer new ways for patients and caregivers to share their personal insights for research and for researchers and treatment developers to learn about those ideas. This project, the "Big Ideas for AD Research", was a global challenge that awarded prizes and recognition to patients' and caregivers' research hypotheses related to atopic dermatitis management, treatment, and prevention.

RESULTS

The Challenge was open for 5 weeks and received 70 submissions from 11 countries. Entries were judged by two separate panels of experts that included both researchers and patients and caregivers. Winners were awarded with a monetary prize, recognized on social media, and connected by Global Parents for Eczema Research staff to an appropriate research group to help further their ideas.

CONCLUSION

The Big Ideas for Eczema Challenge provided a proof of concept for a novel approach to bridging the gap between patients/caregivers and researchers/clinicians by developing a platform to garner the best ideas from the patient community for research. This model could be further leveraged by other patient groups to help solicit patients' and caregivers' ideas for research.

Factors facilitating shared decision making in eczema: Met and unmet needs from the patient perspective

Background

Research has shown that eczema patients prefer some degree of shared control over treatment decisions, but little is known about factors perceived to be important to facilitate shared decision making (SDM).

Objective

To determine factors eczema patients and caregivers consider to be important for SDM, and how often they experience them with their eczema healthcare provider (HCP).

Methods

A cross-sectional survey study (64 questions) was conducted, which included factors related to SDM rated by respondents on a Likert scale for importance, and how often these factors were true with their current eczema HCP.

Results

Respondents (840, response rate 62.4%) most frequently rated their health literacy and communication skills as important for SDM. Factors which indicated a strong provider-patient relationship, and HCPs who initiate treatment conversations were also deemed beneficial. Low importance was placed on concordant HCP race/ethnicity, however, of those who did rate it as important, 53/91 identified as Black (half of all Black respondents).

Limitations

A high proportion of respondents were aware of the term SDM prior to the survey.

Conclusions

SDM is more likely to be facilitated when patient education and empowerment are coupled with HCPs who initiate treatment discussions, maintain compassion resilience, and listen to patient perspectives.

Lithium treatment mitigates the diabetogenic effects of chronic cortico-therapy

BACKGROUND AND PURPOSE

Glucocorticoids (GCs) are the main treatment for autoimmune and inflammatory disorders and are also used as immunosuppressive therapy for patients with organ transplantation. However, these treatments have several side effects, including metabolic disorders. Indeed, cortico-therapy may induce insulin resistance, glucose intolerance, disrupted insulin and glucagon secretion, excessive gluconeogenesis, leading to diabetes in susceptible individuals. Recently, lithium has been shown to alleviate deleterious effects of GCs in various diseased conditions.

EXPERIMENTAL APPROACH

In this study, using two rat models of GC-induced metabolic disorders, we investigated the effects of Lithium Chloride (LiCl) in the mitigation of deleterious effects of GCs. Rats were treated either with corticosterone or dexamethasone, and with or without LiCl. Animals were then assessed for glucose tolerance, insulin sensitivity, in vivo and ex vivo glucose-induced insulin secretion and hepatic gluconeogenesis.

KEY RESULTS

We showed that in rats chronically treated with corticosterone, lithium treatment markedly reduced insulin resistance. In addition, in rats treated with dexamethasone, lithium administration improved glucose tolerance, associated with enhanced insulin secretion in vivo. Moreover, liver gluconeogenesis was reduced upon LiCl treatment. The improvement of insulin secretion in vivo appeared to be due to an indirect regulation of β cell function, since the ex vivo assessment of insulin secretion and β cell mass in islets from animals treated with LiCl revealed no difference compared to untreated animals.

CONCLUSION AND IMPLICATIONS

Collectively, our data provide evidences for the beneficial effects of lithium to mitigate the adverse metabolic effects of chronic cortico-therapy.

Values and Preferences of Patients and Caregivers Regarding Treatment of Atopic Dermatitis (Eczema): A Systematic Review

Importance

Patient values and preferences can inform atopic dermatitis (AD) care. Systematic summaries of evidence addressing patient values and preferences have not previously been available.

Objective

To inform American Academy of Allergy, Asthma & Immunology (AAAAI)/American College of Allergy, Asthma and Immunology (ACAAI) Joint Task Force on Practice Parameters AD guideline development, patient and caregiver values and preferences in the management of AD were systematically synthesized.

Evidence Review

Paired reviewers independently screened MEDLINE, Embase, PsycINFO, and CINAHL databases from inception until March 20, 2022, for studies of patients with AD or their caregivers, eliciting values and preferences about treatment, rated risk of bias, and extracted data. Thematic and inductive content analysis to qualitatively synthesize the findings was used. Patients, caregivers, and clinical experts provided triangulation. The GRADE-CERQual (Grading of Recommendations Assessment, Development and Evaluation-Confidence in the Evidence from Reviews of Qualitative Research) informed rating of the quality of evidence.

Findings

A total of 7780 studies were identified, of which 62 proved eligible (n = 19 442; median age across studies [range], 15 years [3-44]; 59% female participants). High certainty evidence showed that patients and caregivers preferred to start with nonmedical treatments and to step up therapy with increasing AD severity. Moderate certainty evidence showed that adverse effects from treatment were a substantial concern. Low certainty evidence showed that patients and caregivers preferred odorless treatments that are not visible and have a minimal effect on daily life. Patients valued treatments capable of relieving itching and burning skin and preferred to apply topical corticosteroids sparingly. Patients valued a strong patient-clinician relationship. Some studies presented varied perspectives and 18 were at high risk for industry sponsorship bias.

Conclusions and Relevance

In the first systematic review to address patient values and preferences in management of AD to our knowledge, 6 key themes that may inform optimal clinical care, practice guidelines, and future research have been identified.

Assessment of Knowledge, Perception, Experience and Phobia toward Corticosteroids Use among the General Public in the Era of COVID-19: A Multinational Study

BACKGROUND

Corticosteroids play a significant role in managing the vast majority of inflammatory and immunologic conditions. To date, population-based studies on knowledge and attitudes concerning corticosteroids are scarce. This study aims to comprehensively assess knowledge, perception, experience and phobia toward corticosteroid use among the general population in the era of COVID-19.

METHODS

A cross-sectional self-administrated questionnaire was used to collect the data from 6 countries. Knowledge and corticophobia scores, descriptive statistics and logistic regression were computed.

RESULTS

A total of 2354 participants were enrolled in this study; the majority were females (61.6%) with an average age of 30. Around 61.9% had been infected previously with COVID-19, and about one-third of the participants had experience with corticosteroid use. The mean knowledge score was relatively satisfactory (8.7 ± 4.5 out of 14), and Corticophobia ranked a high score in all countries. Age, female gender, and history of COVID-19 were positively correlated with developing corticophobia.

CONCLUSION

Our study highlights that the general knowledge about steroids was satisfactory. However, the phobia toward its use upon indication is high. Therefore, enhancing awareness and providing essential counseling regarding the rational use of corticosteroids may reduce corticophobia.

Community pharmacists' counseling practices and patient experiences about topical corticosteroids - an online survey in the Klang Valley, Malaysia

Background

Community Pharmacists (CPs) play an important role in patient counseling regarding the use of topical corticosteroids (TCS). We assessed CP’s self-reported counseling practices regarding TCS and patients’ reported counseling experiences.

Methods

A previously developed questionnaire was adapted to the Malaysian context. A random sample of 364 registered CPs practicing in three states, Selangor, Kuala Lumpur, and Putrajaya were invited for an online survey. The questionnaire for CPs explored their perceived patient knowledge about topical corticosteroid (TCS) use, their counseling practices, and perceived barriers to counseling. Thirty patients were also selected from five pharmacies i.e., six consecutive patients who consulted each CP were invited to participate in the patient survey by completing a checklist about their experiences regarding the counseling received.

Results

A majority (> 90%) of the CPs mostly explained to the patients that the medication was TCS and the frequency and duration of application but only 10% correctly identified scenarios needing medical referral. Only about half of the CPs always explained about side effects, strength, efficacy, and storage of TCS. The two main barriers were patients’ negative perception of TCS (65.4%) and pharmacists’ lack of time for counseling (49.7%). Counseling practice score was associated with CPs’ age (aOR 0.86, 95%CI 0.78–0.94), pharmacists’ recommendation on TCS use (aOR 0.11, 95%CI 0.02–0.61), and time spent on counseling (aOR 1.42, 95%CI 1.13–1.64). Patients mentioned they were counselled on the frequency and duration of application of TCS, and potential adverse effects. Most were not counselled on action to take when an adverse event occurs and the storage and use of leftover medication.

Conclusion

CPs counseling practices to their patient about the use of TCS requires improvement. Continuing education and hands-on training are needed for CPs regarding counseling about TCS use.

What's New in Topicals for Atopic Dermatitis?

Atopic dermatitis (AD) is a chronic inflammatory skin condition that can have tremendous impact on quality of life for affected children and adults. First-line therapy for acute management of AD includes topical therapies such as corticosteroids, calcineurin inhibitors, and, more recently, the phosphodiesterase inhibitor crisaborole. Topical agents have remained the mainstay therapy for decades; however, there has been a longstanding need for topical therapies with high efficacy and low risk of adverse effects with long-term use. Given the ongoing advances in understanding the pathogenesis of AD, there are novel targets for pharmacological intervention. We are now in an unprecedented time with more than 40 topical treatments in the pipeline for AD in addition to many developments and treatments on the horizon. This review summarizes selected therapeutic topical agents in later phases of development that target various aspects in the pathogenesis of AD such as Janus kinase inhibition (ruxolitinib and delgocitinib), phosphodiesterase-4 inhibition (roflumilast and difamilast), aryl hydrocarbon modulation (tapinarof), and modulation of the microbiome. We also review novel targeted therapies that are in early phase clinical trials, including AMTX-100, BEN-2293, and PRN473. Preliminary findings on efficacy and tolerability of most of these agents are promising, but further studies are warranted to evaluate the long-term safety and efficacy of these novel agents against the current standard of care.

Topical anti‐inflammatory treatments for eczema: network meta‐analysis

This is a protocol for a Cochrane Review (intervention). The objectives are as follows:

To compare the efficacy and safety of topical anti‐inflammatory treatments for reducing eczema symptoms or signs or improving eczema‐related quality of life in children and adults with eczema, by undertaking a network meta‐analysis. To provide a clinically useful ranking of these treatments according to their efficacy and safety.

National Saudi Consensus Statement on the Management of Atopic Dermatitis (2021)

Atopic dermatitis (AD) is a chronic inflammatory skin disease with an increasing prevalence regionally and globally. It is characterized by intense itching and recurrent eczematous lesions. With the increase in the availability of treatment options for healthcare practitioner and patients, new challenges arise for treatment selection and approach. The current consensus statement has been developed to provide up-to-date evidence and evidence-based recommendations to guide dermatologists and healthcare professionals managing patients with AD in Saudi Arabia. By an initiative from the Ministry of Health (MOH), a multidisciplinary work group of 11 experts was convened to review and discuss aspects of AD management. Four consensus meetings were held on January 14, February 4, February 25, and March 18 of 2021. All consensus content was voted on by the work group, including diagnostic criteria, AD severity assessment, comorbidities, and therapeutic options for AD. Special consideration for the pediatric population, as well as women during pregnancy and lactation, was also discussed. The present consensus document will be updated as needed to incorporate new data or therapeutic agents.

Fifteen-minute consultation: How to manage eczema in children

Atopic eczema is common and has a major impact on quality of life. Paediatricians and general practitioners play a key role in the non-specialist treatment of atopic eczema. However, the clinical nature of the diagnosis, multitude of topical therapies and sometimes complicated treatment strategies can leave both clinicians and families feeling bewildered. This article aims to provide a concise, patient-focused summary of the assessment and management of childhood atopic eczema.

Experts' Consensus on the Use of Pimecrolimus in Atopic Dermatitis in China: A TCS-Sparing Practical Approach

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.

Strategies for using topical corticosteroids in children and adults with eczema

BACKGROUND

Eczema is a common skin condition. Although topical corticosteroids have been a first-line treatment for eczema for decades, there are uncertainties over their optimal use.

OBJECTIVES

To establish the effectiveness and safety of different ways of using topical corticosteroids for treating eczema.

SEARCH METHODS

We searched databases to January 2021 (Cochrane Skin Specialised Register; CENTRAL; MEDLINE; Embase; GREAT) and five clinical trials registers. We checked bibliographies from included trials to identify further trials.

SELECTION CRITERIA

Randomised controlled trials in adults and children with eczema that compared at least two strategies of topical corticosteroid use. We excluded placebo comparisons, other than for trials that evaluated proactive versus reactive treatment.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods, with GRADE certainty of evidence for key findings. Primary outcomes were changes in clinician-reported signs and relevant local adverse events. Secondary outcomes were patient-reported symptoms and relevant systemic adverse events. For local adverse events, we prioritised abnormal skin thinning as a key area of concern for healthcare professionals and patients.

MAIN RESULTS

We included 104 trials (8443 participants). Most trials were conducted in high-income countries (81/104), most likely in outpatient or other hospital settings. We judged only one trial to be low risk of bias across all domains. Fifty-five trials had high risk of bias in at least one domain, mostly due to lack of blinding or missing outcome data. Stronger-potency versus weaker-potency topical corticosteroids Sixty-three trials compared different potencies of topical corticosteroids: 12 moderate versus mild, 22 potent versus mild, 25 potent versus moderate, and 6 very potent versus potent. Trials were usually in children with moderate or severe eczema, where specified, lasting one to five weeks. The most reported outcome was Investigator Global Assessment (IGA) of clinician-reported signs of eczema. We pooled four trials that compared moderate- versus mild-potency topical corticosteroids (420 participants). Moderate-potency topical corticosteroids probably result in more participants achieving treatment success, defined as cleared or marked improvement on IGA (52% versus 34%; odds ratio (OR) 2.07, 95% confidence interval (CI) 1.41 to 3.04; moderate-certainty evidence). We pooled nine trials that compared potent versus mild-potency topical corticosteroids (392 participants). Potent topical corticosteroids probably result in a large increase in number achieving treatment success (70% versus 39%; OR 3.71, 95% CI 2.04 to 6.72; moderate-certainty evidence). We pooled 15 trials that compared potent versus moderate-potency topical corticosteroids (1053 participants). There was insufficient evidence of a benefit of potent topical corticosteroids compared to moderate topical corticosteroids (OR 1.33, 95% CI 0.93 to 1.89; moderate-certainty evidence). We pooled three trials that compared very potent versus potent topical corticosteroids (216 participants). The evidence is uncertain with a wide confidence interval (OR 0.53, 95% CI 0.13 to 2.09; low-certainty evidence). Twice daily or more versus once daily application We pooled 15 of 25 trials in this comparison (1821 participants, all reported IGA). The trials usually assessed adults and children with moderate or severe eczema, where specified, using potent topical corticosteroids, lasting two to six weeks. Applying potent topical corticosteroids only once a day probably does not decrease the number achieving treatment success compared to twice daily application (OR 0.97, 95% CI 0.68 to 1.38; 15 trials, 1821 participants; moderate-certainty evidence). Local adverse events Within the trials that tested 'treating eczema flare-up' strategies, we identified only 26 cases of abnormal skin thinning from 2266 participants (1% across 22 trials). Most cases were from the use of higher-potency topical corticosteroids (16 with very potent, 6 with potent, 2 with moderate and 2 with mild). We assessed this evidence as low certainty, except for very potent versus potent topical corticosteroids, which was very low-certainty evidence.  Longer versus shorter-term duration of application for induction of remission No trials were identified. Twice weekly application (weekend, or 'proactive therapy') to prevent relapse (flare-ups) versus no topical corticosteroids/reactive application Nine trials assessed this comparison, generally lasting 16 to 20 weeks. We pooled seven trials that compared weekend (proactive) topical corticosteroids therapy versus no topical corticosteroids (1179 participants, children and adults with a range of eczema severities, though mainly moderate or severe). Weekend (proactive) therapy probably results in a large decrease in likelihood of a relapse from 58% to 25% (risk ratio (RR) 0.43, 95% CI 0.32 to 0.57; 7 trials, 1149 participants; moderate-certainty evidence). Local adverse events We did not identify any cases of abnormal skin thinning in seven trials that assessed skin thinning (1050 participants) at the end of treatment. We assessed this evidence as low certainty. Other comparisons  Other comparisons included newer versus older preparations of topical corticosteroids (15 trials), cream versus ointment (7 trials), topical corticosteroids with wet wrap versus no wet wrap (6 trials), number of days per week applied (4 trials), different concentrations of the same topical corticosteroids (2 trials), time of day applied (2 trials), topical corticosteroids alternating with topical calcineurin inhibitors versus topical corticosteroids alone (1 trial), application to wet versus dry skin (1 trial) and application before versus after emollient (1 trial). No trials compared branded versus generic topical corticosteroids and time between application of emollient and topical corticosteroids.

AUTHORS' CONCLUSIONS

Potent and moderate topical corticosteroids are probably more effective than mild topical corticosteroids, primarily in moderate or severe eczema; however, there is uncertain evidence to support any advantage of very potent over potent topical corticosteroids. Effectiveness is similar between once daily and twice daily (or more) frequent use of potent topical corticosteroids to treat eczema flare-ups, and topical corticosteroids weekend (proactive) therapy is probably better than no topical corticosteroids/reactive use to prevent eczema relapse (flare-ups). Adverse events were not well reported and came largely from low- or very low-certainty, short-term trials. In trials that reported abnormal skin thinning, frequency was low overall and increased with increasing potency. We found no trials on the optimum duration of treatment of a flare, branded versus generic topical corticosteroids, and time to leave between application of topical corticosteroids and emollient. There is a need for longer-term trials, in people with mild eczema.

Steroid Phobia: A Review of Prevalence, Risk Factors, and Interventions

Topical corticosteroid phobia may lead to poor adherence, resulting in persistent disease and escalation to systemic agents. The aim of this paper was to review current literature to assess topical steroid phobia prevalence, populations most at risk, reasons behind steroid phobia, and interventions to reduce it. A systematic search of PubMed, Ovid (Journals@Ovid, MEDLINE), ScienceDirect, and Web of Science was performed. Studies ranged from May 2000 to February 2021. In total, 37 articles met the inclusion criteria. There was inter-study variation in the way steroid phobia is defined, from concern to irrational fear. The worldwide prevalence of topical steroid phobia ranges from 31 to 95.7% and does not differ with patient race/ethnicity or dermatological condition. Female patients and caregivers, and those who have experienced side effects of topical corticosteroids are most likely to express steroid phobia. Reasons for steroid phobia include lack of education, fear of side effects, polypharmacy, misinformation, negative experience with topical steroids, and frequently changing of clinics. Successful interventions to address steroid phobia include patient education in the form of educational videos followed by individualized oral education based on concerns, and demonstrations of application of topical steroids. Multiple interventions address topical corticosteroid phobia and improve adherence of topical corticosteroids in the management of dermatological conditions. Providers should screen patients for steroid phobia, especially in populations particularly at risk. Interventions using patient education should be individualized based on concerns expressed during screening. Further research should investigate if reducing steroid phobia can in fact improve long-term adherence.

Topical treatments in dermatology

Topical medications are key agents in treating a range of skin conditions, as they allow affected areas to be targeted while avoiding systemic side effects. Although there is a wide range of topical agents available, it is helpful to be familiar with a few commonly used formulations. This article describes how to select appropriate agents, prescribe appropriate quantities, and counsel patients on safe and effective treatment regimens.

Assessment of topical steroid phobia in dermatology patients, a cross-sectional study from an urban area of Pakistan

BACKGROUND

Topical corticosteroid (TCS) phobia is a fear of steroids, most prevalent among the general steroid users, the origin of anxiety and fear about steroids is still unclear. Although multiple studies have been using the validated TOPICOP© scale to assess the scores of steroid phobia in various skin disorders.

OBJECTIVES

The aim of the study was to analyze the steroid phobia among users of topical corticosteroids and also to assess the association between demographical characteristics and TCS phobia.

METHODS

A cross-sectional survey was conducted to evaluate the belief and perspectives of TCS in a large range of patients of both genders of all ages. Patients presenting in dermatology clinic with any dermatological complaint, who were being treated or currently on topical steroids were included. TOPICOP© scale was used to assess the topical steroid phobia.

RESULTS

A total of 221 topical steroid users were selected for this study, among them 56 (26.7%) were male and 162 (73.3%) were female. The median of global TOPICOP score was 18% and CI 22-12%, S.D: 6.23. The median score of knowledge and beliefs was 7%, (IQR: 9-4%), S.D: 3.33, while fear showed median 5% (IQR: 7-3%), S.D: 2.24, and 6% (IQR: 8-4%), S.D:2.4 for behavior 96 (43.4%). Patients who were not well aware of steroids but still afraid of using steroids. 112 (50.7%) acknowledged the non-adherence to treatment.

CONCLUSION

Steroid phobia is more prevalent among uneducated users of topical steroids than among those who are knowledgeable and literate. Healthcare practitioners should counsel their patients about steroids use and related concerns, rather than addressing the issue that is causing fear in patients.

Safety of topical corticosteroids in atopic eczema: an umbrella review

OBJECTIVE

An umbrella review summarising all safety data from systematic reviews of topical corticosteroids (TCS) in adults and children with atopic eczema.

METHODS

Embase, MEDLINE, PubMed, Cochrane Database of Systematic Reviews and the Centre of Evidence Based Dermatology map of eczema systematic reviews were searched until 7 November 2018 and Epistemonikos until 2 March 2021. Reviews were included if they assessed the safety of TCS in atopic eczema and searched >1 database using a reproducible search strategy. Review quality was assessed using version 2 of 'A MeaSurement Tool to Assess systematic Reviews' (AMSTAR 2 tool).

RESULTS

38 systematic reviews included, 34 low/critically low quality. Treatment and follow-up were usually short (2-4 weeks).

KEY FINDINGS

TCS versus emollient/vehicle: No meta-analyses identified for skin-thinning. Two 2-week randomised controlled trials (RCTs) found no significant increased risk with very potent TCS (0/196 TCS vs 0/33 vehicle in children and 6/109 TCS vs 2/50 vehicle, age unknown). Biochemical adrenal suppression (cortisol) was 3.8% (95% CI 2.4% to 5.8%) in a meta-analysis of 11 uncontrolled observational studies (any potency TCS, 522 children). Effects reversed when treatment ceased.TCS versus topical calcineurin inhibitors: Meta-analysis showed higher relative risk of skin thinning with TCS (4.86, 95% CI 1.06 to 22.28, n=4128, four RCTs, including one 5-year RCT). Eight cases in 2068 participants, 7 using potent TCS. No evidence of growth suppression.Once daily versus more frequent TCS: No meta-analyses identified. No skin-thinning in one RCT (3 weeks potent TCS, n=94) or biochemical adrenal suppression in two RCTs (up to 2 weeks very potent/moderate TCS, n=129).TCS twice/week to prevent flares ('weekend therapy') versus vehicle: No meta-analyses identified. No evidence of skin thinning in five RCTs. One RCT found biochemical adrenal suppression (2/44 children, potent TCS).

CONCLUSIONS

W e found no evidence of harm when TCS were used intermittently 'as required' to treat flares or 'weekend therapy' to prevent flares. However, long-term safety data were limited.

Practical algorithm to inform clinical decision-making in the topical treatment of atopic dermatitis

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.

Topical therapy of atopic dermatitis with a focus on pimecrolimus

Atopic dermatitis (AD) is a chronic and relapsing, inflammatory skin disease characterized by impaired skin barrier function and immune system dysregulation that results in dryness, skin microbiome dysbiosis and intense pruritus. It is highly heterogeneous, and its management is demanding. Patients with AD are at greater risk of comorbidities such as attention-deficit hyperactivity disorder as well as other atopic diseases. Early-onset AD cases typically improve or resolve in late childhood; however, it is proposed that the prevalence of persistent or adult-onset AD is higher than previously thought. Basic therapy consists of emollient application and trigger avoidance, and when insufficient, topical corticosteroids (TCS) are the first-line treatment. However, corticophobia/steroid aversion and TCS side-effects, particularly on sensitive skin areas, lead to low compliance and insufficient disease control. Several long- and short-term randomized controlled and daily practice studies have demonstrated that topical calcineurin inhibitors, such as pimecrolimus, have similar anti-inflammatory effects to low-to-medium strength TCS, reduce pruritus and improve the quality of life of patients. In addition, pimecrolimus does not cause skin atrophy, is steroid-sparing and has a good safety profile, with no evidence for an increased risk of malignancies or skin infections. In general, pimecrolimus cream is well-accepted and well-tolerated, encouraging patient adherence and leading to its use by many physicians as a preferred therapy for children and sensitive skin areas.

Assessing patients' characteristics and treatment patterns among children with atopic dermatitis

BACKGROUND

Atopic dermatitis (AD) is the most common immune-mediated skin disease in childhood. Several treatment options for pediatric AD, both topical and systemic, are currently available. We carried out a single-center observational study with the aim of describing characteristics and treatment patterns in pediatric AD patients.

METHODS

The study included 867 patients aged ≤16 years (females 50.5%, mean patient's age 5.9 years, standard deviation ±3.6 years) with a previous doctor-confirmed diagnosis of AD who underwent balneotherapy at the Comano Thermal Spring Water Center (Comano, Trentino, Italy) from April to October 2014.

RESULTS

Among the patients included in the study, 41.2% had mild (SCORing Atopic Dermatitis, SCORAD 0-15), 43.6% moderate (SCORAD 16-40) and 15.2% severe AD (SCORAD > 40). A higher occurrence of reported food allergy was observed among children with more severe AD (p < 0.0001), while no association was found between AD severity and reported inhalant allergy or passive smoking (p = 0.15 and 0.92, respectively). Emollients (55.1%) and topical corticosteroids (TCS; 45.7%) were the main treatment options used in the previous month. The use of oral steroids and topical calcineurin inhibitors (TCI) was considerably less common (6.3 and 4.5%, respectively), while no patients were on systemic agents other than steroids. Among patients with severe AD, 9.8% had not used TCS, TCI or any systemic treatments. Moreover, 20.0% of the patients in the study population had followed elimination diets, although only 27.2% of them had a reported food allergy.

CONCLUSIONS

A significant difference in the prevalence of reported food allergy emerged across the different AD severity categories. Furthermore, although further data are necessary to confirm our findings, undertreatment in children with AD appeared to be very common, at least among those attending the Comano Thermal Spring Water Center. Moreover, many patients followed elimination diets in the absence of reported food allergy.

Wikstroemiaganpi Extract Improved Atopic Dermatitis-Like Skin Lesions via Suppression of Interleukin-4 in 2,4-Dinitrochlorobenzene-Induced SKH-1 Hairless Mice

Plants of the genus Wikstroemia are used in Chinese traditional medicine to treat inflammatory diseases, such as arthritis, bronchitis, and pneumonia. The present study was designed to determine whether Wikstroemia ganpi (Siebold and Zucc.) Maxim. offers a potential means of treating 2,4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis (AD) in mice. Symptoms such as redness, edema, and keratinization in AD mice induced by DNCB were alleviated by the co-application of an ethanolic extract of W. ganpi for 2 weeks. The severity of skin barrier function damage was evaluated by measuring TEWL (transepidermal water loss). TEWLs of DNCB sensitized mouse dorsal skin were reduced by the application of a W. ganpi ethanolic extract, and skin hydration was increased. In addition, the infiltration of inflammatory cells into the dermis was significantly reduced, as were blood levels of IgE and IL-4, which play an important role in the expression of AD. The results of this experiment suggest that W. ganpi is a potential therapeutic agent for AD.

Atopic dermatitis: new insight into the etiology, pathogenesis, diagnosis and novel treatment strategies

Atopic dermatitis (AD) is the long-lasting chronic inflammatory skin condition associated with cutaneous hyper-reactivity and triggered by environmental factors. The attributes of AD include dry skin, pruritus, lichenification and frequent eczematous abrasions. This has a strong heritable aspect and typically occurs with asthma and allergic rhinitis. The complex pathological mechanism behind AD etiology is epidermal barrier destruction resulting in the lack of filaggrin protein that can induce inflammation and T-cell infiltration. T-helper 2 cell-mediated pathways also bear the responsibility of damage to the epidermal barrier. Certain causative factors for AD include microbial imbalance of skin microbiota, immunoglobulin-E-induced sensitization and neuro-inflammation. Numerous beneficial topical and oral treatments have been available to patients and there are even more drugs in the pipeline for the treatment of AD. Topical moisturizers, corticosteroids, anti-inflammatory agents such as calcineurin inhibitors, phototherapy, cAMP-specific 3, 5 half-cyclic phosphodiesterase 4 inhibitors and systemic immunosuppressants are widely available for AD treatments. Different positions and pathways inside the immune system including JAK-STAT, phosphodiesterase 4, aryl hydrocarbon receptor and T-helper 2 cytokines are targeted by above-mentioned drug treatments. Instead of the severe side effects of topical steroids and oral antihistamines, herbal plants and their derived phytoconstituents are commonly used for the treatment of AD. A clear understanding of AD's cellular and molecular pathogenesis through substantial advancement in genetics, skin immunology and psychological factors resulted in advancement of AD management. Therefore, the review highlights the recent advancements in the understanding of clinical features, etiology, pathogenesis, treatment and management and non-adherence to AD treatment.

Supporting self-care for eczema: protocol for two randomised controlled trials of ECO (Eczema Care Online) interventions for young people and parents/carers

INTRODUCTION

Eczema care requires management of triggers and various treatments. We developed two online behavioural interventions to support eczema care called ECO (Eczema Care Online) for young people and ECO for families. This protocol describes two randomised controlled trials (RCTs) aimed to evaluate clinical and cost-effectiveness of the two interventions. METHODS AND ANALYSIS: Design: Two independent, pragmatic, unmasked, parallel group RCTs with internal pilots and nested health economic and process evaluation studies. Setting: Participants will be recruited from general practitioner practices in England. Participants: Young people aged 13-25 years with eczema and parents and carers of children aged 0-12 years with eczema, excluding inactive or very mild eczema (five or less on Patient-Oriented Eczema Measure (POEM)). Interventions: Participants will be randomised to online intervention plus usual care or to usual eczema care alone. Outcome measures: Primary outcome is eczema severity over 24 weeks measured by POEM. Secondary outcomes include POEM 4-weekly for 52 weeks, quality of life, eczema control, itch intensity (young people only), patient enablement, health service and treatment use. Process measures include treatment adherence, barriers to adherence and intervention usage. Our sample sizes of 303 participants per trial are powered to detect a group difference of 2.5 (SD 6.5) in monthly POEM scores over 24 weeks (significance 0.05, power 0.9), allowing for 20% loss to follow-up. Cost-effectiveness analysis will be from a National Health Service and personal social service perspective. Qualitative and quantitative process evaluation will help understand the mechanisms of action and participant experiences and inform implementation.

ETHICS AND DISSEMINATION

The study has been approved by South Central Oxford A Research Ethics Committee (19/SC/0351). Recruitment is ongoing, and follow-up will be completed by mid-2022. Findings will be disseminated to participants, the public, dermatology and primary care journals, and policy makers.

TRIAL REGISTRATION NUMBER

ISRCTN79282252.

Healthcare utilization in Danish children with atopic dermatitis and parental topical corticosteroid phobia

BACKGROUND

Atopic dermatitis (AD) is a prevalent relapsing inflammatory skin disease. There is currently little knowledge about healthcare utilization and medication use along with parental corticosteroid phobia in relation to severity of pediatric AD.

OBJECTIVES

To study the association between parental-reported healthcare utilization, medication use, and topical corticosteroid phobia and pediatric AD severity.

METHODS

The study population included all children in Denmark with a diagnostic code of AD (ICD-10 code, group L20) given at a hospital department of dermatology between 2014 and 2018. A questionnaire containing 158 response items was sent to the legal parents. We surveyed disease severity, AD treatment, corticosteroid phobia, and healthcare use along with other variables. Disease severity was assessed using the Patient-Oriented Eczema Measure tool, and corticosteroid phobia was assessed using the Topical Corticosteroid Phobia (TOPICOP) score.

RESULTS

In total, 1343 (39%) parents completed the questionnaire and 95.3% were completed by the biological mother. Children's mean age was 8.9 ± 4.5 years, and 52.8% were boys. Severe AD was associated with a higher number of healthcare visits to GPs, private dermatologists, and hospital departments. Mean global TOPICOP score was 38.27 ± 19.9%. There was a significant inverse linear trend between global TOPICOP score and parental educational level (P_trend  < .0005).

CONCLUSIONS

The significant association between high global TOPICOP score and low parental educational level, resulting in delayed treatment of AD flares, indicates that improved family education ultimately may reduce healthcare expenses and burden of disease.

[Dermocorticoides and sun exposure: A misunderstanding?]

INTRODUCTION

Fear of dermocorticoids (DCs) or corticophobia is based on an overestimation of the risks of actual side effects and on unfounded beliefs such as DCs-induced photosensitivity among community pharmacists. The objective of this study was to assess the community pharmacy teams' fear of dermocorticoids in atopic dermatitis (DA) in sunny weather and its impact on drug use advice.

MATERIAL ET METHODS

A questionnaire as a real case (a summer prescription for atopic dermatitis for an 18-month-old child) was posted on Facebook via groups of pharmacists, technicians and students. Data collected concerned the health professional, his or her reluctance to DCs, advice associated with dispensation, detailed concerns about the DC and sun association, and sources of information.

RESULTS

In total, 126 participants responded (48.4% pharmacists, 40.5% technicians, 10.3% students): 12% were reluctant to DCs, 36% were reluctant to DCs and considered them photosensitizing, and 51% were not reluctant but considered them photosensitizing. The impact on the patient advice was: a suggestion to stop DC during sun exposure (28%), to stop or limit DC (dose, duration) (43%). Concerns about the association DC/sun were mainly due to UV rays (46%). Sources cited were: monographs (54%), Internet (6%), training courses (13%).

CONCLUSION

The false belief of DC/sun incompatibility in DA is strong among pharmacists and impacts on patients' advice. The role of the official team in dispensing dermocorticoids is essential: training and information for professionals helps to fight false information.

Influence of pH-responsive compounds synthesized from chitosan and hyaluronic acid on dual-responsive (pH/temperature) hydrogel drug delivery systems of Cortex Moutan

The polysaccharide-based pH-responsive compounds, namely, N,N,N-trimethyl chitosan (TMC), polyethylene glycolated hyaluronic acid (PEG-HA), and polysaccharide-based nano-conjugate of hyaluronic acid, chitosan oligosaccharide and alanine [HA-Ala-Chito(oligo)] were chemically synthesized using biopolymers chitosan and hyaluronic acid, and applied here to observe the changes in morphology, pH-stability, mechanical and drug-release behavior, and cytotoxicity of thermo-responsive polymer: Poloxamer 407 (PF127)-based drug delivery systems for traditional Chinese medicine Cortex Moutan (CM). The thermo-responsive hydrogel of PF127 loaded with CM (Gel^C) was used as control. The dual-responsive (pH/temperature) hydrogels: PF127/TMC/PEG-HA (Gel¹) and PF127/HA-Ala-Chito(oligo) (Gel²) showed improved mechanical behavior as obtained by rheology and mechanical agitation study, and pH-stability under various external pH conditions, and those improvements occurred due to the addition of polysaccharide-based pH-responsive compounds in the systems. Both, Gel¹ and Gel² showed better morphology than Gel^C as obtained by SEM or TEM suggesting that interaction of polysaccharide-based pH-responsive compounds with PF127 in either gel or sol state gave better porous network structure in the hydrogels or more dispersed micellar arrangements in sol-state, respectively. Gel¹ showed the highest cumulative drug release (86.5%) after 5 days under mild acidic condition (pH 6.4) suggesting that release behavior of a hydrogel drug carrier was dependent on morphology, mechanical behavior, and pH-stability. The transdermal release (ex-vivo) results indicated that gallic acid, the active marker of CM passed through porcine ear skin and all the formulations showed more or less similar transdermal release properties. The hydrogels loaded with CM showed no cytotoxicity (cell viability >90.0%) on human HaCaT keratinocytes within concentration range of 0.0-20.0 μg/ml as obtained by MTT assay, and cell viability was more than 100% at a concentration of 20.0 μg/ml for Gel². The formulations without loaded drug namely, Gel¹-CM and Gel²-CM exhibited strong anti-bacterial action against gram positive bacteria Staphylococcus aureus.

Atopic dermatitis epidemiology and unmet need in the United Kingdom

Atopic dermatitis (AD), also known as atopic eczema, is a chronic inflammatory skin condition associated with a significant health-related and socioeconomic burden, and is characterized by intense itch, disruption of the skin barrier, and upregulation of type 2-mediated immune responses. The United Kingdom (UK) has a high prevalence of AD, affecting 11-20% of children and 5-10% of adults. Approximately 2% of all cases of childhood AD in the UK are severe. Despite this, most AD treatments are performed at home, with little contact with healthcare providers or services. Here, we discuss the course of AD, treatment practices, and unmet need in the UK. Although the underlying etiology of the disease is still emerging, AD is currently attributed to skin barrier dysfunction and altered inflammatory responses. Management of AD focuses on avoiding triggers, improving skin hydration, managing exacerbating factors, and reducing inflammation through topical and systemic immunosuppressants. However, there is a significant unmet need to improve the overall management of AD and help patients gain control of their disease through safe and effective treatments. Approaches that target individual inflammatory pathways (e.g. dupilumab, anti-interleukin (IL)-4 receptor α) are emerging and likely to provide further therapeutic opportunities for patient benefit.

Paediatric atopic eczema (atopic dermatitis) in South Africa: A practical algorithm for the management of mild-to-moderate disease in daily clinical practice

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).

Treatment of adult atopic dermatitis patients according to disease characteristics and demographics

Little is currently known about possible associations between disease specific characteristics of atopic dermatitis (AD) and use of medical treatments. We explored the use of AD treatments within the past 12 months in Danish adults according to distinct patient characteristics. Patients who had received a diagnosis of AD in a hospital in- or outpatient setting as adults were surveyed and data cross-linked to a national prescription registry. AD severity was measured by the Patient-Oriented SCORing Atopic Dermatitis (PO-SCORAD). A total of 3834 patients participated. Use of topical medication in the past 12 months increased with increasing AD severity, whereas no difference was observed for systemic medication use. Positive associations between AD in the face and neck, and use of mild and moderately potent topical corticosteroids were observed, while involvement of palms and chest was associated with use of more potent topical corticosteroids. The mean DLQI, skin pain, and itch severity scores were lower in patients managed only with topical corticosteroids (5.5, 3.2, and 4.3, respectively) compared to patients treated with both oral and topical medication (7.1, 3.8, and 5.0, respectively). Patients with frequent topical corticosteroid use tended to be older (50.7 vs 48.6 years), males (50.0% vs 33.6%), current daily smokers (17.3% vs 13.7%), and having asthma (59.1% vs 43.8%) compared with infrequent users of topical corticosteroids. We found a disconnect between the severity of AD signs and symptoms, and use of AD therapies. In particular, a very modest use of systemic immunosuppressants was seen even among patients with severe AD symptoms. However, the underlying clinical decisions and reasons behind this disconnect is not clear based on the current data.
