Qualitative study with mothers of children with atopic dermatitis: emotional and social impacts.

INTRODUCTION: Atopic Dermatitis (AD) is the most common skin disease in childhood and its control requires the support of the family members. This disease significantly interferes with the Quality of Life (QoL) of children and families, however, literature on the social and emotional impact of the disease on the caregivers is lacking. OBJECTIVE: To evaluate the emotional and social impact of AD on mothers of children with the disease. METHOD: This is a qualitative study of semi-structured interviews with mothers of children diagnosed with AD. The following variables were evaluated: diagnosis and start of treatment, knowledge about the disease, and impact on the mothers' lives. The material was analyzed using Lawrence Bardin's content analysis technique. The AD severity was assessed by SCORAD. RESULTS: A total of 23 interviews were conducted with mothers of children diagnosed with AD. In 82.6% of the cases, the mothers presented conflicts in the face of the first contacts with the disease. In 43.5% of cases, mothers were solely responsible for their children's treatment. About 56.6% defined AD as a cause of suffering and difficulty and 21.7% pointed out the AD experience as a learning experience. CONCLUSION: The AD is a chronic disease that has a psychological and social impact on the lives of mothers. In the treatment of AD, mothers must be screened and offered psychological support to improve adherence to treatment in the long term.

Patients' and Caregivers' Experiences Navigating the Burden of Atopic Dermatitis in Argentina.

Background and Objectives: Little is known about patients' and caregivers' experiences with atopic dermatitis (AD) in Argentina, so a survey was administered to learn more. Materials and Methods: A 53-item anonymous survey was administered in Spanish to adult AD patients (n = 334) and caregivers (n = 339) of pediatric AD patients in Argentina (total n = 673). Demographics, healthcare provider information, financial burden, disease severity, disease burden, level of disease-specific education, and experience with shared physician/patient decision making were collected. Linear and logistic regression models were used for statistical comparisons. Results: Survey respondents were overwhelmingly female (90.8%), as was the overall patient population (72.8%). Patients were seen mostly by healthcare specialists (66.8% dermatologists, 13.5% pediatricians, 7.7% allergists, and 7.2% general practitioners). Only 2.8% of respondents reported no symptoms, while 33.3%, 52.4%, and 11.5% reported mild, moderate, and severe AD disease, respectively. Anxiety/depression and pain/discomfort were the most impactful on respondents' quality of life. Caregivers of children with moderate to severe AD and adult patients with severe AD reported a significant financial burden, including using savings or not purchasing food or other essentials to afford medical care. Few people reported receiving disease-specific education or having their own treatment priorities taken into consideration. For adult patients, receiving disease education and being asked about treatment priorities were associated with higher treatment satisfaction and AD control. Discussion: Mental health, pain/discomfort, and financial worries are the most important burdens for adult AD patients and caregivers of children with AD in Argentina. We recommend prioritizing disease-specific education and shared decision making to improve AD care in Argentina.

Are behavioral interventions a better choice for atopic dermatitis patients? A meta-analysis of 6 randomized controlled trials.

BACKGROUND: The treatment for atopic dermatitis (AD) has been the focus of clinical research, and behavioral intervention is considered an indispensable treatment method. To our knowledge, no relevant meta-analysis has evaluated the effects of behavioral interventions on atopic dermatitis. OBJECTIVES: To evaluate the effects of behavioral interventions on atopic dermatitis. METHODS: The authors searched PubMed, EMBASE, and Cochrane CENTRAL to retrieve relevant RCTs (up to Feb 2022). The search strategy involved a combination of related keywords. The Cochrane Q and I2 statistics were used to assess heterogeneity. RESULTS: Six RCTs involving seven reports with 246 patients were included. The results suggested that behavioral interventions could relieve eczema severity (correlation coefficient [r = -0.39]; p < 0.001) and scratching severity significantly (r = -0.19; p = 0.017), while not affect itching intensity (r = -0.02; p = 0.840). A sensitivity analysis confirmed the robustness of the results. STUDY LIMITATIONS: An important limitation of this study was the insufficient number of RCTs and the limited sample size. In addition, the study lacked a control group receiving a type of intervention other than the experimental protocol. Another limitation was the short duration of follow-up. CONCLUSIONS: This study suggests that behavioral interventions could be effective in treating atopic dermatitis by reducing eczema and scratching severity. Additionally, habit-reversal behavioral therapy may be more effective for treating atopic dermatitis.

[Guidelines on atopic dermatitis for Mexico (GUIDAMEX): using the ADAPTE methodology]. / Guía de dermatitis atópica para México (GUIDAMEX): lineamientos usando metodología ADAPTE.

With the advancement of knowledge in relation to the physiopathogenesis of atopic dermatitis (AD), several new therapeutic forms have been developed. There are also new guidelines for self-care. On the other hand, there is still an underdiagnosis of AD in Mexico. Thus, the need was seen to develop a national guide, with a broad base among the different medical groups that care for patients with AD. The Atopic Dermatitis Guidelines for Mexico (GUIDAMEX) was developed with the ADAPTE methodology, with the endorsement and participation of ten national medical societies, from physicians in Primary Healthcare to allergists and dermatologists. Throughout the manuscript, key clinical questions are answered that lead to recommendations and suggestions for the diagnosis of AD (including differential diagnosis with immunodeficiency syndromes), the recognition of comorbidities and complications, non-pharmacological treatment including therapeutic education, treatment of flares and maintenance therapy. The latter encompasses general measures to avoid triggering factors, first-line treatment focussed on repair of the skin barrier, second-line treatment (topical proactive therapy), and third-line phototherapy or systemic treatment, including dupilumab and JAK inhibitors.

Con el avance de los conocimientos en relación con la fisiopatogenia de la dermatitis atópica (DA) se han desarrollado varias formas terapéuticas nuevas. Asimismo, existen nuevos lineamientos para el autocuidado. Por otro lado, aún existe un subdiagnóstico de la DA en México. Así, se vio la necesidad de desarrollar una guía nacional, con base amplia entre las diferentes agrupaciones médicos que atienden pacientes con DA. Se desarrolló la Guía de DA para México (GUIDAMEX) con la metodología ADAPTE, con el aval y la participación de diez sociedades médicas nacionales, desde médicos del primer contacto hasta alergólogos y dermatólogos. A lo largo del escrito se contestan preguntas clínicas clave que llevan a recomendaciones y sugerencias para el diagnóstico de la DA (incluyendo diagnóstico diferencial con síndromes de inmunodeficiencia), el reconocer de las comorbilidades y complicaciones, las medidas generales (tratamiento no farmacológico) incluyendo la educación terapéutica, el tratamiento de los brotes y el tratamiento de mantenimiento. Este último abarca las medidas generales de evitar agravantes, el tratamiento de primera línea reparador de la barrera cutánea, de segunda línea (manejo proactivo tópico), hasta la fototerapia y el tratamiento sistémico de la tercera línea, incluyendo dupilumab y los inhibidores de la cinasa de Jano.

Acupuncture attenuates comorbid anxiety- and depressive-like behaviors of atopic dermatitis through modulating neuroadaptation in the brain reward circuit in mice.

Atopic dermatitis (AD) is highly comorbid with negative emotions such as anxiety and depression. Although acupuncture has demonstrated efficacy in AD, its influence on comorbid anxiety and depression remains unclear. We sought to explore the impact and mechanisms of action of acupuncture on comorbid anxiety and depression of AD. AD-like skin lesions were induced by the topical application of MC903 to the mouse cheek. Acupuncture was performed at Gok-Ji (LI11) acupoints. AD-like phenotypes were quantified by lesion scores, scratching behavior, and histopathological changes. The effects of acupuncture on comorbid anxiety and depression-like behaviors were assessed using the elevated plus-maze (EPM), open-field tests (OFT), and tail-suspension test (TST). In addition, biochemical changes in the brain reward regions were investigated by immunoblotting for the expression of tyrosine hydroxylase (TH), dopamine D1 receptor (D1R), phospho-dopamine and cAMP-regulated phosphoprotein-32 kDa (pDARPP-32), phospho-cAMP response element binding protein (pCREB), ΔFosB, and brain-derived neurotrophic factor (BDNF) in the nucleus accumbens, dorsolateral striatum, and ventral tegmental area. Acupuncture effectively improved the chronic itching and robust AD-like skin lesions with epidermal thickening. Additionally, it considerably reduced comorbid anxiety- and depression-like symptoms, as indicated by more time spent in the open arms of the EPM and in the center of the open field and less time spent immobile in the TST. Higher pCREB, ΔFosB, BDNF, and pDARPP-32 levels, and reduced TH and D1R protein expression in the brain reward regions of AD mice were reversed by acupuncture treatment. The beneficial effects of acupuncture on clinical symptoms (scratching behavior) and comorbid psychological distress in AD strongly correlated with dorsal striatal ΔFosB levels. Collectively, these data indicate that acupuncture had a significant, positive impact on comorbid anxiety- and depression-like behaviors by modulating neuroadaptation in the brain reward circuit in mice with AD, providing a novel perspective for the non-pharmacological management of psychiatric comorbidities of AD.

The use of azathioprine in atopic dermatitis: A review.

Most patients with atopic dermatitis (AD) have a good response to topical treatment. However, some need systemic therapy in order to satisfactorily control the disease. Azathioprine is an accessible drug for patients in many countries, including underdeveloped countries, and therefore it is used by many dermatologists in moderate and severe AD. It is important to have a deep knowledge and understanding about this drug since it is an alternative therapy as a steroid-sparing agent and an affordable one. However, when it comes to systemic therapy for AD, it is not always clear its indications and it is necessary to have a closer follow-up of the patient. In this paper, we describe thoroughly its indications in AD, the mechanism of action of the drug, as well as the interactions, adverse effects, adequate monitoring, and precautions in special population that must be considered when prescribing azathioprine. This review will help dermatologists prescribe it safely to all patients who require it.

Designing an Atopic Dermatitis Community that Integrates Patient Self-Uploaded Information into the EHR to Optimize Follow-up.

Atopic dermatitis is a common chronic dermatological disease in childhood that can affect people's quality of life. The aim of this study was to inquire about the difficulties, needs and interests related to the disease that people with eczema and their caregivers have; in order to develop a tool that is useful for the follow-up of the illness. Electronic surveys were sent to potential users and interviews were conducted with professionals who are specialized on the subject. The main findings allowed us to understand the challenges and situations they face on a daily basis, such as the difficulties related to the family support, the queries on the eczema flare-ups, the struggles with the adherence to treatment and the needs of optimizing their quality of life. These results helped us design a tool that allows patients and their companions to better monitor their disease while optimizing communication with their health professionals.

ECHO project in atopic dermatitis in Argentina: An innovative strategy to reach underserved areas with up to date knowledge, first year of experience.

BACKGROUND: The ECHO® (Extension for Community Healthcare Outcomes) project is a model of distance medical education developed in the United States to support health professionals in the management of patients with complex diseases. Since 2019, it has been implemented in atopic dermatitis (AD) in Argentina. The program consists of the periodic presentation of clinical cases by videoconference, virtual classes, and a permanently available open chat between professionals in charge of patients with AD and a group of experts. OBJECTIVE: The objective of this study was to analyze the impact of the ECHO Project AD on the medical knowledge and medical skills of Argentinian health professionals when treating patients with AD. METHODS: A survey was carried out among the participants in order to evaluate the impact of the program on the care of patients with AD. RESULTS: ECHO Project AD revealed a significant improvement in the management of patients with AD. The program contributed to the interpretation and use of severity scores, use of phototherapy, and management and prescription of both classic and innovative topical and systemic treatments. STUDY LIMITATIONS: The reduced number of participants and the short period of time. The answers of the survey may be biased by the enthusiasm of the participants. CONCLUSIONS: The ECHO project is an educational tool that enhances the medical skills of doctors and institutions, in which a climate of a partnership comes first and the participants look forward to learning from experiences, successes, and mistakes from one another, producing a scientific hub in constant evolution.

The Keratinocyte as a Crucial Cell in the Predisposition, Onset, Progression, Therapy and Study of the Atopic Dermatitis.

The keratinocyte (KC) is the main functional and structural component of the epidermis, the most external layer of the skin that is highly specialized in defense against external agents, prevention of leakage of body fluids and retention of internal water within the cells. Altered epidermal barrier and aberrant KC differentiation are involved in the pathophysiology of several skin diseases, such as atopic dermatitis (AD). AD is a chronic inflammatory disease characterized by cutaneous and systemic immune dysregulation and skin microbiota dysbiosis. Nevertheless, the pathological mechanisms of this complex disease remain largely unknown. In this review, we summarize current knowledge about the participation of the KC in different aspects of the AD. We provide an overview of the genetic predisposing and environmental factors, inflammatory molecules and signaling pathways of the KC that participate in the physiopathology of the AD. We also analyze the link among the KC, the microbiota and the inflammatory response underlying acute and chronic skin AD lesions.

[The annual cost of medical care for patients with moderate to severe atopic dermatitis in Mexico. A multicenter study]. / Costo anual de la atención médica de pacientes con dermatitis atópica moderada a grave en México. Estudio multicéntrico.

BACKGROUND: In Mexico, the economic burden of medical care for patients with atopic dermatitis is unknown. OBJECTIVE: To determine the annual direct medical costs of the treatment for patients with moderate to severe atopic dermatitis who receive medical attention at "Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado" (Institute for Social Security and Social Services for State Workers, better known as ISSSTE), as well as the main variables associated with it. METHODS: A multicenter, retrospective cohort study. Clinical records of patients with moderate to severe atopic dermatitis were reviewed and a multivariate analysis was designed by using a generalized linear model. RESULTS: 65 patients were included; 41 of them (63.07 %) had moderate atopic dermatitis, and 24 (36.92 %) had severe AD; 39 (60 %) of them were female patients. In groups with severe atopic dermatitis, statistically significant differences were observed in matters of the duration of the evolution of the disease, comorbidities, intense pruritus, and depression. The average annual cost of medical care for patients with moderate atopic dermatitis was 1527 ± 623 USD, and for patients with severe atopic dermatitis the cost was 9487 ± 8990 USD. Significant differences were observed in dermatology consultations, referrals, laboratory and diagnostic studies, and the number of drugs prescribed by physicians. With the multivariate analysis, it was identified that the highest cost was presented by severe patients (p = 0.0001) who were younger and had comorbidities, along with diagnosis of depression. CONCLUSIONS: The severity of atopic dermatitis, the age average, the presence of comorbidities, and the diagnosis of depression are the variables with the highest association and impact on the direct cost of medical care.

Objetivo: Determinar los costos médicos directos anuales del tratamiento de pacientes con dermatitis atópica moderada y grave que se atienden en el Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado, y las principales variables asociadas. Métodos: Estudio multicéntrico de cohorte retrospectiva. Se revisaron los expedientes clínicos de pacientes con dermatitis atópica clasificada como moderada o grave y se diseñó un modelo de análisis multivariado mediante un modelo lineal generalizado. Resultados: Se incluyeron 65 pacientes, 41 (63.07 %) tuvieron dermatitis atópica moderada y 24 (36.92 %), grave; 39 (60 %) fueron del sexo femenino. En los grupos con dermatitis atópica grave se observaron diferencias estadísticamente significativas en años de evolución de la enfermedad, comorbilidades, prurito intenso y depresión. El costo promedio anual de la atención médica para dermatitis atópica moderada fue de 1527 ± 623 USD y para dermatitis atópica grave, de 9487± 8990 USD. Se obtuvieron diferencias estadísticamente significativas en consultas de dermatología, interconsultas, estudios de laboratorio y gabinete y número de medicamentos prescritos. Con el análisis multivariado se identificó que el costo mayor lo presentaban los pacientes graves (p = 0.0001), más jóvenes, con comorbilidades y diagnóstico de depresión. Conclusiones: La gravedad de la dermatitis atópica, la edad, presentar comorbilidades y contar con el diagnóstico de depresión son las variables con mayor asociación e impacto en el costo directo de la atención médica.

Inhibitory effects of Aristotelia chilensis water extract on 2,4-Dinitrochlorobenzene induced atopic-like dermatitis in BALB/c Mice.

BACKGROUND: Maqui berry (Aristotelia chilensis) has been reported to have anti-glycation, anti-inflammation, lipogenesis-inhibiting activities highly related to its anti-oxidation function, but practical efficacy studies on immunological mechanisms for atopic dermatitis, have not been reported yet. OBJECTIVE: This study investigated the immune regulation mechanism of Aristotelia chilensis water extract (ACWE) related to atopic-like dermatitis . METHODS: Antioxidant and anti-inflammatory effects of ACWE was assayed. Atopy inhibitory effect was evaluated using in vitro cell study and in vivo 2,4-dinitrochlorobenzene (DNCB)-induced mouse atopic-like dermatitis model. RESULTS: ACWE has good antioxidant activities, and atopic indications were improved in ACWE group in DNCB-induced atopic-like dermatitis model of BALB/c mice. In spleen cells from mice, ACWE increased interferon-gamma (IFN-γ) levels, and decreased interleukin-4 (IL-4) levels compared with the DNCB control. CONCLUSIONS: ACWE was efficacious for atopic dermatitis which indicates that ACWE might have potential as an agent for atopic dermatitis.

[Epidemiological study on atopic dermatitis in Mexico]. / Estudio epidemiológico sobre dermatitis atópica en México.

BACKGROUND: There is limited epidemiological information on the treatment of atopic dermatitis (AD) from specialist physicians in Mexico. OBJECTIVE: To know the criteria that is used by specialists in Mexico to diagnose and treat AD. METHODS: An observational, descriptive and cross-sectional study, which was authorized by the ethics committee, was carried out through an electronic survey. RESULTS: 114 surveys were carried out; 56% of the participants were allergists, 38% were dermatologists and 5% were pediatricians. It was identified that 54% used clinical criteria for the diagnosis of AD and 42% used the criteria of Hanifin-Rajka as a diagnostic complement; 38% requested total and/or specific IgE, blood biometry and blood chemistry tests. They recount that 90% of patients under the age of 18 had mild AD, 8% had moderate AD and 2% had severe AD; and, in patients over the age of 18, 89% had mild AD, 6% had moderate AD and 5% had severe AD. The patients' care was multidisciplinary, since 57% of the survey respondents requested assessments combined with ophthalmology, dermatology and allergology. CONCLUSION: Knowledge of the disease will lead to a better control of the disease. The challenge is to have a patient registry, update treatment guidelines, consider comorbidities and have therapeutic options for its control.

Antecedentes: Existe escasa información epidemiológica sobre el tratamiento de la dermatitis atópica (DA) por parte de los médicos especialistas en México. Objetivo: Conocer los criterios utilizados para el diagnóstico y tratamiento de la DA por los especialistas en México. Métodos: Estudio observacional, descriptivo y transversal, autorizado por el comité de ética, mediante una encuesta electrónica. Resultados: Se realizaron 114 encuestas, 56 % de los participantes fueron alergólogos, 38 % dermatólogos y 5 % pediatras. Se identificó que 54 % utilizaba criterios clínicos para realizar el diagnóstico de DA y 42 %, los criterios de Hanifin-Rajka; como complemento diagnóstico, 38 % solicitaba IgE total o específica, biometría hemática y química sanguínea. Los encuestados refirieron que 90 % de los menores de 18 años presentaba DA leve, 8 % moderada y 2 % grave; y los mayores de esa edad, 89 % leve, 6 % moderada y 5 % grave. La atención del paciente era multidisciplinaria, ya que 57 % de los encuestados solicitaba valoraciones conjuntas con oftalmología, dermatología y alergología. Conclusión: El conocimiento de la DA propiciará un mejor control de la enfermedad. El reto es contar con un registro de pacientes, actualizar las guías de tratamiento, considerar comorbilidades y contar con opciones terapéuticas para su control.
