Unveiling the potential: Enhancing caregiver knowledge through video education to address topical corticosteroid concerns in children with eczematous dermatitis. Pediatr Dermatol 2024; 41:221-228. [PMID: 38126606 DOI: 10.1111/pde.15430] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Accepted: 09/04/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND Concerns about the use of topical corticosteroids (TCS) in pediatric eczematous dermatitis management often hinder effective treatment. Limited data exist regarding the prevalence of these concerns and the effectiveness of interventions. This study aimed to assess the prevalence of TCS concerns among caregivers and determine the effectiveness of video education in mitigating these concerns. METHODS A single-center prospective study was conducted from 2022 to 2023, involving caregivers of children under 18 years with eczematous dermatitis. Baseline and post-intervention questionnaires were administered after a 4-week period. Caregivers received video education on TCS use, and the TOPICOP score was evaluated before and after viewing the video. RESULTS The study included 150 caregivers, 85.3% female and 74% had a child with atopic dermatitis. The prevalence of TCS concerns among Thai caregivers was 62%. Following video education, the prevalence of TCS concerns significantly decreased to 10.7%. Mean belief score decreased from 43.81 ± 13.45 to 31.85 ± 16.56, mean worry score decreased from 56.22 ± 18.27 to 40.41 ± 18.55 and mean total TOPICOP score decreased from 50.02 ± 12.65 to 36.13 ± 13.52 (p-value <.001). The intervention also resulted in reduced disease exacerbations, duration of the rash, and duration of TCS use. The optimal TOPICOP cut-off score to predict TCS concerns was identified as 43.06. CONCLUSION Video education effectively alleviated TCS concerns among caregivers, addressing beliefs, worries, disease exacerbations, and side effects. Integration of this intervention into the management of pediatric eczematous dermatitis can yield optimal outcomes.

Topical corticosteroid phobia in adolescents with eczema and caregivers of children and adolescents with eczema: A cross-sectional survey. Pediatr Dermatol 2023; 40:135-138. [PMID: 36400426 DOI: 10.1111/pde.15183] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/01/2022] [Accepted: 10/18/2022] [Indexed: 11/20/2022]
Abstract
Steroid phobia is an increasing phenomenon that affects treatment adherence. The purpose of this study was to assess the prevalence and associated factors of steroid phobia among adolescents with eczema and the caregivers of children and adolescents with eczema by using questionnaires and TOPICOP© scale. The prevalence of steroid phobia is approximately 12% and 37% in the adolescent and caregiver groups, respectively. Caregivers who obtained information about topical corticosteroid (TCS) from dermatologists and whose children had fewer number of flares, demonstrated less concern about using TCS.

Abstract
Atopic dermatitis (AD) is a chronic skin disease with increasing prevalence worldwide. It is characterized by pruritic eczematous lesions, affecting up to 20% of the children and negatively impacting their quality of life. Guidelines for AD management are available worldwide, but specific guidelines for pediatric AD in Saudi Arabia are lacking. This consensus document aims to identify the needs for the diagnosis and management of pediatric AD in Saudi Arabia by gathering the opinions and recommendations of key experts. We conducted a three-step modified Delphi method to develop the present consensus. The experts agreed that pediatricians and dermatologists commonly encounter AD; however, it is still under-recognized in its early stage in Saudi Arabia. The family physicians should be involved in assessing suspected children with a family history of atopy, particularly in patients with isolated lesions. Further, the experts confirmed that AD diagnosis should be documented, showing assessment criteria used, key morphological characteristics, and features used to ascertain the severity of the disease. There is still a need for simple validated diagnostic criteria suitable for daily practice for pediatric AD. The experts highlighted several medical conditions that pertain to the diagnosis and management of AD in Saudi Arabia.

Abstract
OBJECTIVE To explore the phenomenon of topical corticosteroid (TCS) phobia and comprehensively understand the factors driving TCS concerns, in particular pertaining to steroid addiction and withdrawal. DESIGN Prospective qualitative study using 1:1 in-depth semistructured interviews and analysed using grounded theory. PARTICIPANTS Patients with a prior experience of TCS use for a dermatological condition recruited from a tertiary academic dermatology clinic, or through word of mouth and online social media platforms. RESULTS 26 participants encompassing those with positive, neutral and negative opinions towards TCS were interviewed. 13 reported having topical steroid addiction or withdrawal. The drivers of TCS concerns could be categorised into seven themes: attitudes towards TCS (comprising beliefs and knowledge about TCS), availability of alternatives, treatment inconvenience, personality, patient's ongoing evaluation of clinical response to TCS, doctor-patient relationship and healthcare-seeking behaviour. Of mention, patients placed high value and trust on their own experiences with TCS, such as their perceived experienced side effects. The doctor who failed to acknowledge the patient's opinions and instead emphasised the safety of TCS was often viewed as dismissive, resulting in a deteriorating patient-doctor relationship. CONCLUSION Provision of knowledge and education is important but may be ineffective if the basis for TCS concern regarding safety is reasonable, or when the patient has a firmly established belief supporting his/her concern. In such instances, failure to acknowledge and respect the patient's decision to avoid TCS could worsen the doctor-patient relationship.

Abstract
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.

Abstract
Introduction Adoption of control tools for atopic dermatitis (AD) in Latin America (LA) is currently very limited. Clinical assessment tools represent a practical method to measure the impact of treatment on disease activity and on the quality of life of patients. However, the use of these tools in the LA clinical practice setting is limited. Methods A selected panel of Latin American experts in fields related to atopic dermatitis were provided with a series of relevant questions to address prior to the multi-day conference. Within this conference, each narrative was discussed and edited by the entire group, through numerous drafts and rounds of discussion, until a consensus was achieved. Results The panel proposes specific and realistic recommendations for implementing control tools for AD care in LA. In creating these recommendations, the authors strove to address all barriers to the widespread use of these tools. Conclusion This article includes a narrative analysis of barriers to AD control in LA and provides necessary recommendations to integrate and increase the use of validated AD control assessment tools throughout the region.

Abstract
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.

Abstract
INTRODUCTION Patient education is crucial for improving disease outcomes in atopic dermatitis (AD). This review aims to summarize evidence about the effectiveness of educational programs for parents of pediatric AD patients. METHODS PubMed and Embase (inception to Feb 2020) were searched and randomized controlled trials (RCTs) in English were included. Risk of bias was assessed using Cochrane risk of bias tools and quality of evidence was assessed by Grading of Recommendations Assessment, Development and Evaluation (GRADE). Pooled standardized mean difference (SMD) and 95% confidence intervals (CIs) were calculated for the disease severity instrument (Scoring of Atopic Dermatitis, SCORAD) and quality of life (QoL) instruments using the random-effects model. RESULTS A total of 13 RCTs were included in the systematic review. The meta-analysis of SCORAD contained seven studies with a total of 1853 patients. The reduction in disease severity (SCORAD) was larger in the treatment group (SMD = - 8.22, 95% CI = - 11.29, - 5.15; P < 0.001; I2 = 78.6%). Subgroup analyses revealed that the association was modified by the frequency of sessions (P for Cochran Q < 0.01) and the duration of follow-up (P for Cochran Q < 0.01). No significant effect-modification was observed for disease severity and borderline significance was observed for session delivery (individual vs group session). The pooled effect sizes for QoL measures including Dermatitis Family Index (SMD = - 0.65, 95% CI = - 1.49, 0.18), Children's Dermatology Life Quality Index (SMD = - 1.61, 95% CI = - 3.76, 0.55; I2= 89.0%) and Infants' Dermatology Quality of Life Index (SMD = 0.30, 95% CI = - 1.04, 1.63; I2= 63.1%) were not significant. CONCLUSIONS Structured patient education is beneficial and should be implemented for the management of AD patients. However, an optimal delivery mode needs to be determined.

Abstract
INTRODUCTION Topical corticosteroids (TCS) are commonly used in dermatology for their anti-inflammatory action. The recent development of the TOPICOP© (Topical Corticosteroid Phobia) scale to assess steroid phobia has made the quantification and comparison of steroid phobia easier. The objective of this study was to assess the degree of steroid phobia at our institute and identify sources from which patients obtain information regarding TCS. METHODS A cross-sectional survey was performed of dermatology patients regardless of steroid use. TOPICOP scale was used for the survey. Sources from which patients obtained information were identified and their level of trust in these sources assessed. RESULTS 186 surveys were analysed. The median domain TOPICOP subscores were 38.9% (interquartile range [IQR] 27.8%-50.0%, standard deviation [SD] 24.4%) for knowledge and beliefs, 44.4% (IQR 33.3%-66.7%, SD 24.4%) for fears and 55.6% (IQR 33.3%-66.7%, SD 27.2%) for behaviour. The median global TOPICOP score was 44.4% (IQR 33.3%-55.6%, SD 17.6%). Female gender was associated with higher behaviour, fear and global TOPICOP scores. There was no difference in the scores based on disease condition, steroid use, age or education. Dermatologists were the most common source of information on topical steroids and trust was highest in dermatologists. CONCLUSION The prevalence of steroid phobia in our dermatology outpatient setting was moderately high, with gender differences. Dermatologists were the most common source of information on TCS, and it was heartening to note that trust was also highest in dermatologists. Strategies to target steroid phobia should take into account these factors.

Abstract
BACKGROUND/OBJECTIVES The TOPICOP scale is an easy-to-use scale for assessing topical corticosteroid (TCS) phobia in atopic dermatitis (AD) patients and their caretakers. TCS phobia is a common problem among AD patients and their caretakers. The aim of this study was to examine the relationship between TCS phobia in caretakers of children with AD and the characteristics of patients using the TOPICOP scale. METHODS Caretakers of AD patients who visited the allergy clinic at the National Center for Child Health and Development in Tokyo between February 2014 and May 2014 were recruited. Caretakers of patients in follow-up had already attended an education session on treatment at the institution. All participants completed an anonymous questionnaire on the characteristics of the respondents and patients using the Patient-Oriented Eczema Measure (POEM) and the Japanese version of TOPICOP. RESULTS In total, 243 participants (88.9% female) completed the survey. The average TOPICOP score was 40.3 and the median POEM score was 4. The TOPICOP score was significantly higher for patients younger than 12 months old with moderate to very severe AD (POEM ≥ 8) whose caretaker had not attended an educational session (P < 0.01, respectively). There was no significant difference in the family history of AD, age, or gender of the respondents. In multivariable analysis, preattendance at an education session was the only significant factor accounting for a higher TOPICOP score (P < 0.001). CONCLUSIONS Regardless of their background, caretakers of AD patients can be affected from TCS phobia. Attending an educational session might ease their anxiety.

Abstract
BACKGROUND Adherence to topical corticosteroids is low among atopic dermatitis patients and their parents. This can lead to treatment failure and decreased quality of life. OBJECTIVE To assess and compare the worries and beliefs concerning topical corticosteroids among parents of children with atopic dermatitis, involved health care professionals, and between different professionals. Also, we identify factors associated with corticosteroid phobia (corticophobia) in professionals. METHODS Parents and health care professionals were invited to complete a questionnaire about corticophobia (Topicop). Higher questionnaire scores, expressed as a percentage, indicate more severe corticophobia. Professionals were asked to answer the questions as though they were using topical corticosteroids on their own child. RESULTS The scores for 29 parents and 31 public health care nurses were equal: 44%. The score for 51 general practitioners was 39%. The score for 33 public health care physicians and of 47 pediatricians was 31%. The differences between parents and these professionals were statistically significantly different (P = 0.001). Type of profession and having a child with atopic dermatitis were significantly associated factors for the score. CONCLUSION Corticophobia is present among parents of children with atopic dermatitis and among health care professionals involved in caring for children with atopic dermatitis. Health care nurses express the same level of corticophobia as parents. The presence of corticophobia among health care professionals may affect parental perspectives and topical corticosteroids adherence negatively.

Abstract
Background Atopic dermatitis (AD) is a common skin condition among Asians. Recent studies have shown that Asian AD has a unique clinical and immunologic phenotype compared with European/American AD. Objective The Asian Academy of Dermatology and Venereology Expert Panel on Atopic Dermatitis developed this reference guide to provide a holistic and evidence-based approach in managing AD among Asians. Methods Electronic searches were performed to retrieve relevant systematic reviews and guidelines on AD. Recommendations were appraised for level of evidence and strength of recommendation based on the U.K. National Institute for Health and Care Excellence and Scottish Intercollegiate Guidelines Network guidelines. These practice points were based on the consensus recommendations discussed during the Asia Pacific Meeting of Experts in Dermatology held in Bali, Indonesia in October 2016 and April 2017. Results The Expert Panel recommends an approach to treatment based on disease severity. The use of moisturizers is recommended across all levels of AD severity, while topical steroids are recommended only for flares not controlled by conventional skin care and moisturizers. Causes of waning efficacy must be explored before using topical corticosteroids of higher potency. Topical calcineurin inhibitors are recommended for patients who have become recalcitrant to steroid, in chronic uninterrupted use, and when there is steroid atrophy, or when there is a need to treat sensitive areas and pediatric patients. Systemic steroids have a limited role in AD treatment and should be avoided if possible. Educational programs that allow a patient-centered approach in AD management are recommended as an adjunct to conventional therapies. Recommendations on the use of phototherapy, systemic drugs, and emerging treatments are also included. Conclusion The management of AD among Asians requires a holistic approach, integrating evidence-based treatments while considering accessibility and cultural acceptability.

Abstract
BACKGROUND Atopic dermatitis (AD) and psoriasis are chronic inflammatory cutaneous disorders for which the gold standard treatment is topical corticosteroids. Although fears about topical corticosteroids are known to be a primary cause of poor therapeutic adherence in AD, this has not been evaluated in psoriasis. TOPICOP is a helpful and easy-to-use tool for the evaluation of topical corticosteroid concerns (TCC). It may help clinicians improve adherence to treatment and correct misconceptions. OBJECTIVE We aimed to compare the TCC of parents of children with psoriasis or AD using the TOPICOP scale and a visual analog scale (VAS). METHODS We performed a cross-sectional multicenter study in nine French hospitals from 1 October 2015 to 31 May 2016. The TOPICOP scale was developed for patients with AD and comprises 12 questions to assess patients' worries and beliefs about topical corticosteroids, with a maximum score of 36. We used a standardized questionnaire to collect epidemiologic and medical data, and the parents completed the TOPICOP scale and VAS (score 0-10). RESULTS A total of 122 children were enrolled (61 patients in each group). The mean Physician Global Assessment was 2.1 in the psoriasis group, and the mean SCORing AD index was 33.3 in the AD group. The TOPICOP score was 16.0 in the psoriasis group and 18.8 in the AD group (p = 0.10). The VAS score was 5.6 and 5.1 in the psoriasis and AD groups, respectively (p = 0.18). The mean TOPICOP score was higher if the mother answered (p < 0.0001; odds ratio 12.3; 95% confidence interval 9.2-15.5). In the AD group, the mean TOPICOP score was higher if follow-up for the child was as an outpatient (p = 0.018). In the psoriasis group, the mean TOPICOP score was higher if patients were seen for the first time (p = 0.047). CONCLUSION Using the TOPICOP questionnaire and a VAS, we found the level of TCC for the parents of pediatric patients with psoriasis to be similar to that for parents of pediatric patients with AD. As TCC is an issue in patients with psoriasis, future research is warranted to assess whether therapeutic education lessens TCC and improves treatment outcomes.

Abstract
INTRODUCTION Local adverse effects of steroid use and the burning sensation of calcineurin inhibitors impair patients' adherence to treatment and decrease the treatment response in atopic dermatitis (AD). Steroid phobia appears to be a psychological problem in patients with AD. Topical non-steroidal remedies are in demand. Areas covered: This manuscript reviews the current literature on preclinical and clinical studies regarding topical E6005/RVT-501, a novel phosphodiesterase 4 inhibitor. We also discuss the mechanistic background of E6005/RVT-501 in the treatment of AD. Expert opinion: Topical E6005/RVT-501 improves skin eruption and pruritus of pediatric and adult AD patients without any serious side effects. It is useful for mild to moderate lesions of AD in pediatric and adult patients. Topical E6005/RVT-501 is non-steroidal agent but its potency is equal to that of mild rank topical steroid, therefore, it may fit the demand of patients with steroid phobia. Its steroid-sparing effects may also be investigated in future clinical trials and may minimize the dose and frequency of topical steroids.

Abstract
Centella asiatica has potent antioxidant and anti-inflammatory properties. However, its anti-dermatitic effect has not yet been reported. In this study, we investigated the anti-dermatitic effects of titrated extract of Centella asiatica (TECA) in a phthalic anhydride (PA)-induced atopic dermatitis (AD) animal model as well as in vitro model. An AD-like lesion was induced by the topical application of five percent PA to the dorsal skin or ear of Hos:HR-1 mouse. After AD induction, 100 μL of 0.2% and 0.4% of TECA (40 μg or 80 μg/cm2) was spread on the dorsum of the ear or back skin three times a week for four weeks. We evaluated dermatitis severity, histopathological changes and changes in protein expression by Western blotting for inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and NF-κB activity, which were determined by electromobility shift assay (EMSA). We also measured TNF-α, IL-1β, IL-6, and IgE concentration in the blood of AD mice by enzyme-linked immunosorbent assay (ELISA). TECA treatment attenuated the development of PA-induced atopic dermatitis. Histological analysis showed that TECA inhibited hyperkeratosis, mast cells and infiltration of inflammatory cells. TECA treatment inhibited expression of iNOS and COX-2, and NF-κB activity as well as the release of TNF-α, IL-1β, IL-6, and IgE. In addition, TECA (1, 2, 5 μg/mL) potently inhibited Lipopolysaccharide (LPS) (1 μg/mL)-induced NO production, expression of iNOS and COX-2, and NF-κB DNA binding activities in RAW264.7 macrophage cells. Our data demonstrated that TECA could be a promising agent for AD by inhibition of NF-κB signaling.
