ABSTRACT

A Dermatite Atópica e a Epidermólise Bolhosa são doenças crônicas que afetam a estrutura morfológica e bioquímica da pele, provocando lesões e alterações sistêmicas nos indivíduos afetados, podendo ocasionar infecções generalizadas. Este estudo teve como objetivo avaliar e sintetizar as contribuições das pesquisas produzidas sobre os cuidados de enfermagem para crianças com dermatite atópica ou epidermólise bolhosa. Trata-se de uma revisão integrativa, cuja pergunta norteadora foi: "Quais são os cuidados de enfermagem para o paciente pediátrico com dermatite atópica ou epidermólise bolhosa?". Sua busca aconteceu nas bases de dados: Medline; CINAHL; LILACS e CUIDEN. Não houve restrição quanto ao ano de publicação e foram analisados estudos publicados nos idiomas inglês, português e espanhol. Como resultados foram incluídos 23 estudos, dois quais duas categorias foram elencadas: Assistência de Enfermagem às Crianças Portadoras de Dermatite Atópica e a Epidermólise Bolhosa e, Educação em Saúde. Evidenciou-se a necessidade de investimento em pesquisas bem delineadas sobre o tema, pois a raridade da condição, a escassez de referencial e a dificuldade em encontrar pacientes aptos para intervenções são fatores que contribuem neste cenário científico.


The Atopic Dermatitis and Epidermolysis Bullosa are chronic diseases that affect the morphological and biochemical structure of the skin, causing lesions and systemic changes in affected individuals, which can lead to generalized infections. This study aimed to evaluate and synthesize the contributions of research produced on nursing care for children with atopic dermatitis or epidermolysis bullosa. This is an integrative review, whose guiding question was: "What is the nursing care for pediatric patients with atopic dermatitis or epidermolysis bullosa?". Your search took place in the following databases: Medline; CINAHL; LILACS and CUIDEN. There was no restriction on the year of publication and studies published in English, Portuguese and Spanish were analyzed.

ABSTRACT

BACKGROUND@#Atopic dermatitis (AD) affects approximately 10% of adults worldwide. CM310 is a humanized monoclonal antibody targeting interleukin-4 receptor alpha that blocks interleukin-4 and interleukin-13 signaling. This trial aimed to evaluate the efficacy and safety of CM310 in Chinese adults with moderate-to-severe AD.@*METHODS@#This multicenter, randomized, double-blind, placebo-controlled, phase 2b trial was conducted in 21 medical institutions in China from February to November 2021. Totally 120 eligible patients were enrolled and randomized (1:1:1) to receive subcutaneous injections of 300 mg CM310, 150 mg CM310, or placebo every 2 weeks for 16 weeks, followed by an 8-week follow-up period. The primary endpoint was the proportion of patients achieving ≥75% improvement in the Eczema Area and Severity Index (EASI-75) score from baseline at week 16. Safety and pharmacodynamics were also studied.@*RESULTS@#At week 16, the proportion of EASI-75 responders from baseline was significantly higher in the CM310 groups (70% [28/40] for high-dose and 65% [26/40] for low-dose) than that in the placebo group (20%[8/40]). The differences in EASI-75 response rate were 50% (high vs . placebo, 95% CI 31%-69%) and 45% (low vs . placebo, 95% CI 26%-64%), with both P values <0.0001. CM310 at both doses also significantly improved the EASI score, Investigator's Global Assessment score, daily peak pruritus Numerical Rating Scale, AD-affected body surface area, and Dermatology Life Quality Index compared with placebo. CM310 treatment reduced levels of thymus and activation-regulated chemokine, total immunoglobulin E, lactate dehydrogenase, and blood eosinophils. The incidence of treatment-emergent adverse events (TEAEs) was similar among all three groups, with the most common TEAEs reported being upper respiratory tract infection, atopic dermatitis, hyperlipidemia, and hyperuricemia. No severe adverse events were deemed to be attributed to CM310.@*CONCLUSION@#CM310 at 150 mg and 300 mg every 2 weeks demonstrated significant efficacy and was well-tolerated in adults with moderate-to-severe AD.

ABSTRACT

Objective To explore the significance of interleukin-17C(IL-17C)-mediated follicular helper T cell (Tfh) differentiation in atopic dermatitis (AD) model. Methods BALB/c mice were divided into control group, AD model group, low-dose MOR106 (anti-IL-17C huIgG1)(MDR106-L)treatment group and high-dose MOR106 (MOR106-H) treatment group, 8 mice in each group. Except for the control group, all the other groups were treated with 2, 4- dinitrochlorobenzene (DNCB) to establish AD models. The low-dose and high-dose MOR106 groups were treated with 5 mg/kg or 10 mg/kg MOR106 respectively. The differentiation of Tfh cell subsets in peripheral blood of mice was analyzed by flow cytometry, and the expression of Janus kinase 2/signal transducer and activator of transcription 3(JAK2/STAT3) signal pathway protein in skin tissue was detected by Western blot analysis. Results Compared with the control group, the dermatitis severity score, mass difference between two ears, spleen mass and spleen index of DNCB group increased significantly, while those of MOR106-L group and MOR106-H group decreased significantly. Compared with the control group, the Tfh subgroup of AD mice showed deregulated differentiation, resulting in a significant increase in the percentage of CD4+CXCR5+IFN-γ+Tfh1 cells, CD4+CXCR5+IL-17A+Tfh17 and CD4+CXCR5+IL-21+Tfh21 cells, and a significant decrease in the percentage of CD4+CXCR5+IL-10+Tfh10 cells and CD4+CXCR5+FOXP3+Tfr cells in peripheral blood. The protein levels of phosphorylated JAK2(p-JAK2) and p-STAT3 were significantly increased. MOR106 effectively reversed these changes of Tfh1, Tfh10, Tfh17, Tfh21 and Tfr cells in peripheral blood of AD mice. Compared with AD group, the levels of p-JAK2 and p-STAT3 protein in low-dose and high-dose MOR106 treatment groups decreased significantly. Conclusion MOR106 can reduce the inflammatory response of AD mice by blocking JAK2/STAT3 signaling pathway and inhibiting the differentiation of Tfh cells mediated by IL-17C.

ABSTRACT

La dermatitis atópica (DA) es una enfermedad inflamatoria de la piel de alta prevalencia en pediatría, de acuerdo a estudios internacionales. Existe escasa información sobre las características epidemiológicas en la población pediátrica Argentina. El objetivo fue describir la prevalencia y características clínicas de la DA en una población de niños argentinos atendidos en el servicio de pediatría de un hospital general. Estudio observacional, de corte transversal. Se incluyeron 500 pacientes al azar, media de edad de 10 años (DE 5), el 50 % (250) de sexo femenino, de los cuales 24 presentaron DA. La prevalencia global fue del 5 % (IC95 % 3-7) y 3/24 fueron formas graves. La comorbilidad atópica más frecuente fue asma. La DA es una enfermedad con una prevalencia en nuestra población similar a la de otros países. Nuestro estudio aporta nuevos datos acerca de las características epidemiológicas de la dermatitis atópica en nuestra región


Atopic dermatitis (AD) is an inflammatory skin disease highly prevalent in pediatrics as per international studies. There is scarce information on the epidemiological characteristics of AD in the Argentine pediatric population. The objective of this study was to describe the prevalence and clinical characteristics of AD in a population of Argentine children seen at the Department of Pediatrics of a general hospital. Observational, cross-sectional study. Five hundred patients were randomly included; their mean age was 10 years (SD: 5); 50% (250) were female. A total of 24 had AD. The overall prevalence was 5% (95% confidence interval: 3­7) and 3/24 were severe forms. The most frequent atopic comorbidity was asthma. The prevalence of AD in our population is similar to that of other countries. Our study provides new data on the epidemiological characteristics of AD in our region.

ABSTRACT

Introduction: Atopic dermatitis, also known as eczema or atopic eczema, is a chronic inflammatory skin disorder characterized by the presence of pruritus accompanied by itching. In Colombia, epidemiological and healthcare resource utilization information regarding this pathology is limited. Objective: To describe atopic dermatitis epidemiological characteristics and healthcare resource utilization patterns in Colombia. Materials and methods: A retrospective database study using real-world data obtained from the national claims database SISPRO (Sistema de Información para la Protección Social) for the 2015-2020 period was carried out. Sociodemographic (age, and health services delivery), epidemiological (incidence, prevalence, and comorbidities), and healthcare resource utilization data were extracted from the SISPRO database. Results: The epidemiological results showed increased incidence and prevalence of atopic dermatitis in Colombia in the 2018-2019 period compared to 2015-2017. Accordingly, the number of medical consultations (particularly with specialists), the number of procedures, and the number of hospitalizations of patients with atopic dermatitis increased. Topic and systemic corticoids were the most frequently prescribed drugs. Conclusions: Diagnoses of atopic dermatitis in Colombia increased with a concomitant increase in healthcare resource utilization during 2015-2020, which was possibly slowed down by the arrival of the Covid-19. This study may help physicians gaining a better understanding of the disease, improving atopic dermatitis patient management.


Introducción. La dermatitis atópica, también conocida como eczema o eczema atópico, es un trastorno inflamatorio crónico de la piel caracterizado por la presencia de prurito acompañado de picor. En Colombia, la información epidemiológica y de utilización de recursos sanitarios sobre esta enfermedad es limitada. Objetivo. Describir las características epidemiológicas y los patrones de utilización de recursos sanitarios para la dermatitis atópica en Colombia. Materiales y métodos. Se trata de un estudio retrospectivo en el cual se utilizan datos de la práctica clínica real obtenidos del registro nacional SISPRO (Sistema de Información para la Protección Social) en el período 2015-2020. Se extrajeron datos sociodemográficos (incluida la edad y la prestación de servicios de salud), epidemiológicos (incluidos la incidencia, la prevalencia y las comorbilidades) y los correspondientes a la utilización de los recursos sanitarios. Resultados. Los resultados epidemiológicos han demostrado un aumento de la incidencia y prevalencia de la dermatitis atópica en Colombia en el periodo 20182019, en comparación con el periodo 2015-2017. Aumentó el número de consultas médicas (particularmente, con especialistas) de pacientes con dermatitis atópica, el de procedimientos y el de hospitalizaciones. Los corticoides tópicos y sistémicos fueron los medicamentos más prescritos. Conclusiones. Los diagnósticos de dermatitis atópica en Colombia aumentaron con un incremento concomitante en la utilización de recursos sanitarios durante 2015-2020, que posiblemente se vio atenuado por la llegada del Covid-19. Este estudio puede ayudar a los médicos a tener un mejor conocimiento de la enfermedad y, por lo tanto, mejorar el tratamiento de los pacientes con dermatitis atópica.

ABSTRACT

Abstract The objective of this paper was to develop and evaluate two semi-solid pharmaceutical forms containing 0.1% tacrolimus: cream (CRT01) and gel (GLT01). For the evaluation of physicochemical stability, at times 0, 30, 60 and 90 days, at 23°C and at 40°C, High Performance Liquid Chromatography coupled with a Diode Array Detector (HPLC-DAD) was employed. This method was developed and validated for tacrolimus quantification. The occlusivity test and skin permeation assay were also performed, using an animal model (Wistar rats), and the CRT01 and GLT01 were compared to the 0.1% tacrolimus ointment (PFU01) obtained from the University Pharmacy, Federal University of Rio de Janeiro, Brazil. CRT01 and GLT01 presented a homogeneous aspect and consistency adequate for topical products, along with sensory characteristics above PFU01. They also presented adequate physicochemical stability for 90 days and a lower occlusive effect than PFU01 (p<0.05). CRT01 showed greater affinity for the skin when compared to PFU01 and GLT01, with low systemic absorption. The CRT01 semi-solid formulation was considered the most adequate one to treat patients with atopic dermatitis or other dermatologic inflammatory diseases, promoting rational use of tacrolimus

ABSTRACT

To assess the reliability, validity and responsiveness of the Chinese version of the atopic dermatitis control tool (ADCT). After this study obtained authorization for the Chinese version of the ADCT scale. 114 patients with atopic dermatitis were enrolled from the Department of Dermatology, Peking University First Hospital using convenience sampling from October 2022. Patients were surveyed using the General Information Questionnaire, Chinese version of ADCT, patient-oriented eczema measure (POEM),peak pruritus numerical rating scale (PP-NRS),dermatology life quality index (DLQI) and the global patient self-assessment for disease severity. Mann-Whitney rank sum test and Spearman correlation analysis were used for item analysis; content validity was assessed using content validity index (CVI); exploratory factor analysis was used to assess structural validity; Cronbach' alpha coefficient was used to assess internal consistency; Spearman correlation analysis was used to assess the correlation of ADCT with other scales to assess external responsiveness. The results showed that all items were retained by item analysis. I-CVI was 0.9-1, and S-CVI/Average was 0.983; the scale extracted one common factor by factor analysis, the cumulative variance explanation rate was 77.927%; the Cronbach' alpha coefficient of the scale was 0.937; the correlation coefficients of the Chinese version of ADCT with POEM, PP-NRS, and DLQI were 0.805, 0.861, and 0.709 respectively. In conclusion, the Chinese version of the ADCT has adequate reliability, validity and responsiveness, and is suitable for measuring disease control in Chinese patients with atopic dermatitis.

ABSTRACT

OBJECTIVES@#Ozone is widely applied to treat allergic skin diseases such as eczema, atopic dermatitis, and contact dermatitis. However, the specific mechanism remains unclear. This study aims to investigate the effects of ozonated oil on treating 2,4-dinitrochlorobenzene (DNCB)-induced allergic contact dermatitis (ACD) and the underling mechanisms.@*METHODS@#Besides the blank control (Ctrl) group, all other mice were treated with DNCB to establish an ACD-like mouse model and were randomized into following groups: a model group, a basal oil group, an ozonated oil group, a FcεRI-overexpressed plasmid (FcεRI-OE) group, and a FcεRI empty plasmid (FcεRI-NC) group. The basal oil group and the ozonated oil group were treated with basal oil and ozonated oil, respectively. The FcεRI-OE group and the FcεRI-NC group were intradermally injected 25 µg FcεRI overexpression plasmid and 25 µg FcεRI empty plasmid when treating with ozonated oil, respectively. We recorded skin lesions daily and used reflectance confocal microscope (RCM) to evaluate thickness and inflammatory changes of skin lesions. Hematoxylin-eosin (HE) staining, real-time PCR, RNA-sequencing (RNA-seq), and immunohistochemistry were performed to detct and analyze the skin lesions.@*RESULTS@#Ozonated oil significantly alleviated DNCB-induced ACD-like dermatitis and reduced the expressions of IFN-γ, IL-17A, IL-1β, TNF-α, and other related inflammatory factors (all P<0.05). RNA-seq analysis revealed that ozonated oil significantly inhibited the activation of the DNCB-induced FcεRI/Syk signaling pathway, confirmed by real-time PCR and immunohistochemistry (all P<0.05). Compared with the ozonated oil group and the FcεRI-NC group, the mRNA expression levels of IFN-γ, IL-17A, IL-1β, IL-6, TNF-α, and other inflammatory genes in the FcεRI-OE group were significantly increased (all P<0.05), and the mRNA and protein expression levels of FcεRI and Syk were significantly elevated in the FcεRI-OE group as well (all P<0.05).@*CONCLUSIONS@#Ozonated oil significantly improves ACD-like dermatitis and alleviated DNCB-induced ACD-like dermatitis via inhibiting the FcεRI/Syk signaling pathway.

ABSTRACT

Introducción: La dermatitis atópica es un trastorno cutá-neo atópico, inflamatorio de tipo crónico con aparición más frecuente en niños antes de los 5 años de edad. El objetivo del presente estudio fue determinar factores de riesgo clínicos y sociodemográficos asociados a dermatitis atópica en un grupo de niños escolares en Riobamba-Ecuador. Métodos: El presente estudio observacional incluyó escolares en el periodo junio - agosto 2020. Con una muestra probabilística se incluyeron casos con dermatitis atópica (DA) y un grupo control. Las variables fueron Dermatitis atópica, edad, sexo, antecedentes familiares y personales de atopia, exposición materna al humo del tabaco en el período de gestación o en la infancia, duración de lactancia materna exclusiva, nivel de instrucción de los padres, tipo de residencia, tipo de familia, presencia de niños mayores y mascotas en casa, frecuencia de aseo, duración de la ducha. Se pre-senta Odds Ratio con el inter-valo de confianza del 95%. Resultados: Se incluyeron 175 escolares, 28 (14.2%) con DA. OR para exposición a tabaquismo pasivo en la infancia = 3.7, OR para familias pequeñas = 2.5 (P=0.042), OR para el antecedente materno de rinitis alérgica 2.6, OR para dermatitis atópica en padres = 9.0. Conclusión: Se confirma que el antecedente familiar de enfermedades como rinitis alérgica y dermatitis atópica así como el antecedente personal de enfermedades que forman parte del espectro atópico diferentes de DA, la exposición al humo del tabaco en el hogar y la convivencia con un reducido número de integrantes dentro de la familia son factores de riesgo asociados a dermatitis atópica.


Introduction: Atopic dermatitis is a chronic inflammatory atopic skin disorder with the most frequent onset in children under five. This study aimed to determine clinical and socio-demographic risk factors associated with atopic dermatitis in a group of school children in Riobamba, Ecuador. Methods: The present observational study included school-children in the period June - August 2020. A probabilistic sample included cases with atopic dermatitis (AD) and a control group. The variables were atopic dermatitis, age, sex, family and personal history of atopy, maternal exposure to tobacco smoke during pregnancy or in childhood, duration of exclusive breastfeeding, parental educational level, type of residence, family type, presence of older children and pets at home, frequency of grooming, and duration of showering. The odds ratio is presented with a 95% confidence interval. Results: A total of 175 school-children were included, 28 (14.2%) with AD. Alternatively, for exposure to secondhand smoke in childhood = 3.7, OR small families = 2.5 (P =0.042) OR for maternal history of allergic rhinitis 2.6, OR atopic dermatitis in parents = 9.0. Conclusion: It is confirmed that the family history of diseases such as allergic rhinitis and atopic dermatitis, as well as the personal history of diseases that are part of the atopic spectrum other than AD, expo-sure to tobacco smoke at home and living with a small number of members within the family, are risk factors associated with atopic dermatitis.

ABSTRACT

Introdução: O quadro da dermatite atópica (DA) é caracterizado por prurido crônico de evolução flutuante, que pode resultar em distúrbios no padrão de sono e em estigmatização social devido à presença de lesões visíveis e recidivantes, as quais tendem a se tornar progressivamente liquenificadas. Fatores como os já citados e outros associados, como incapacidade laboral, falta de concentração ao longo do dia e isolamento apresentam-se como profundos impactantes para a saúde mental do paciente, podendo resultar em baixa autoestima, depressão e frustração. Além disso, sabe-se que a DA é uma doença essencialmente inflamatória, ao mesmo tempo em que estudos recentes demonstram papel de citocinas no desenvolvimento de síndromes depressivas, podendo haver correlação causal entre os quadros por vias inflamatórias. Objetivos: Essa revisão sistemática de literatura objetivou analisar a relação entre dermatite atópica e sintomas depressivos, identificando possíveis mecanismos responsáveis por essa ligação. Métodos: A busca foi feita entre 17/11/2020 e 18/11/2020 seguindo o modelo PRISMA e utilizando as bases PUBMED, Biblioteca Virtual em Saúde (BVS) - IBECS, LILACS e CUMED - e EMBASE. As palavras-chave "Depression" e "Atopic Eczema", em conjunto com seus termos MeSh e DECS, foram utilizadas e associadas através do método booleano. Critérios para inclusão foram definidos como artigos que são ensaios clínicos ou observacionais envolvendo grupo de pacientes com dermatite atópica e grupo controle, que pôde ser constituído pelo próprio grupo com dermatite atópica, porém, após intervenção. Os sintomas depressivos precisavam ser medidos por escalas ou terem critérios para diagnóstico de síndrome depressiva estabelecidos. A seleção foi feita por todos os autores de forma independente, sendo discordâncias solucionadas por consenso. Resultados: Ao final, quinze estudos restaram, os quais foram classificados entre aqueles que comparam tratamentos e seus desfechos relacionados à depressão e DA, aqueles que propõem DA como agravante de sintomas depressivos, aqueles que propõem sintomas depressivos como agravantes da DA e aqueles que trazem análises estatísticas sem estabelecer claramente onde reside a relação de causalidade entre os dois quadros. Conclusões: Diversos estudos mostraram a existência de relação entre o quadro de DA e sintomas depressivos em vias distintas, tanto analisando a DA como agravante de sintomas depressivos como vice-versa. A partir dessa perspectiva, é possível que haja uma causalidade bidirecional cíclica, na qual um constante feedback positivo gera piora de ambos os quadros até que a abordagem adequada seja tomada, evidenciando a importância da propedêutica multidisciplinar para esses pacientes (AU)


Introduction: Atopic dermatitis (AD) is characterized by chronic itching, presenting with fluctuating evolution, resulting in sleep disorders and social stigmatization due to the presence of visible and recurrent lesions, that might become progressively lichenified. Factors such as those mentioned and others associated, such as incapacity for work, lack of concentration throughout the day and isolation have profound impacts on the patient's mental health, resulting in low self-esteem, depression and frustration. In addition, it is known that AD is essentially an inflammatory disease. And, recent studies demonstrate the role of inflammatory cytokines in the development of depressive syndromes, therefore may be a causal correlation between the conditions by inflammatory pathways. Objectives: This systematic literature review aimed to analyze a relationship between atopic dermatitis and depressive symptoms, identifying mechanisms responsible for this connection. Methods: The research was carried out between 11/17/2020 and 11/18/2020 following the PRISMA model and using PUBMED, Virtual Health Library (VHL) - IBECS, LILACS and CUMED - and EMBASE databases. Keywords "Depression" and "Atopic Eczema", along with its MeSh and DECS terms, were used and associated using the Boolean method. Inclusion criteria were defined as articles that are clinical or observational trials involving a group of patients with atopic dermatitis and a control group, which could be constituted by the group with atopic dermatitis itself, however, after an intervention. The depressive symptoms had to be measured by scales or, at least, the criteria for diagnosis of depressed syndrome must have been established. Results:In the end, fifteen studies remained, which were classified among those that compare treatments and their outcomes related to depression and AD, those that propose AD as an aggravator of depressive symptoms, those that propose depressive symptoms as an aggravating factor for AD and those that bring statistical analysis without clearly establishing where the causality relation resides. Conclusion: Several studies have presented a relationship between the condition of AD and depressive symptoms in distinct pathways, or analyzing AD as an aggravating factor for depressive symptoms or vice-versa. From this perspective, there may be a cyclical bidirectional causality, in which constant positive feedback generates worsening of both conditions until the adequate approach is taken, highlighting the importance of the multidisciplinary propaedeutics for these patients (AU)

ABSTRACT

Fundamentals: Atopic Dermatitis (AD) and Psoriasis (PS) share clinical and physiopathological similarities. Objective: Determine the prevalence of sensitization to Malassezia spp. in adults with AD and PS and its correlation with disease severity. Methods: A cross-sectional study was carried out from January 2016 to August 2017 with adults. Malassezia spp.-specific IgE dosages were measured, and skin scrapings for fungal culture performed. Parametric or nonparametric tests were used for analysis. Results: Median age of the 20 participants with AD was 29 years old, and the mean SCO-RAD was 45.35 ± 18.32. Malassezia spp.- specific IgE median dosage was 0.63 kU/l. M. furfur and M. sympodialis were isolated. Spearman's nonparametric correlation analysis showed no correlation between sensitization to Malassezia spp. and disease severity. The median age of the 36 participants with PS was 61 years old, the median body surface area affected was 22%, and Malassezia spp.-specific IgE median dosage was 0.00 kU/l. M. furfur and Malassezia spp. were identified. Study limitations: Assessing the sensitization to Malasseziaspp. was difficult due to the reduced number of participants in the study. Furthermore, there was no uniformity in the location to collect skin scrapings. The use of topical medication was not suspended before collecting skin specimens for mycological examination, therefore interfer-ing with fungal isolation. Conclusion: Sensitization to Malassezia spp. was only detected in the AD sample. Malassezia spp.-specific IgE test did not prove to be a marker for disease severity in our AD sample (AU)


Fundamentos: Dermatite atópica (DA) e psoríase apresentam similaridades clínicas e fisiopatológicas. Objetivos: Avaliar a frequência da sensibilização a Malasseziaspp. em adultos portadores de DA e psoríase e correlacionar à gra-vidade dos quadros clínicos. Métodos: De janeiro de 2016 a agosto de 2017, conduziu-se um estudo observacional em indivíduos adultos onde foram realizadas dosagem de IgE específica anti-Malassezia spp. e raspados das lesões para cultura micológica. Testes paramétricos ou não paramétricos foram utilizados para análise. Resultados: Nos 20 portadores de DA, a mediana da idade foi 29 anos. O valor médio do Scoring Atopic Dermatitis foi 45,35 ± 18,32. A mediana de IgE específica anti-Malasseziaspp. foi 0,63 kU/l. M. furfur e M. sympodialis foram isolados. A análise de correlação não-paramétrica de Spearman não mostrou correlação entre a sensibilização à Malassezia spp. e a gra-vidade. Nos 36 pacientes com psoríase, foram obtidas as seguintes medianas: idade 61 anos, comprometimento de superfície corpórea 22% e IgE específica anti-Malassezia spp. 0,00 kU/l. Houve identificação de M. furfur e Malasse-zia spp. Limitações do estudo: O número reduzido de participantes dificultou a avaliação da sensibilização por IgE a Malasseziaspp. Não houve uniformidade nos locais de coleta dos raspados cutâneos. Medicamentos tópicos não foram suspensos anteriormente ao exame micológico, prejudicando o isolamento dos fungos. Conclusões: Sensibili-zação a Malassezia spp. apenas ocorreu nos portadores de DA. O teste de IgE específica anti-Malassezia spp. não se mostrou um marcador de gravidade para a DA neste grupo (AU)

ABSTRACT

A alergia ocular, também conhecida como conjuntivite alérgica (CA), é uma reação de hipersensibilidade mediada por imunoglobulina E (IgE) do olho desencadeada por aeroalérgenos, principalmente ácaros da poeira doméstica e pólen de gramíneas. Os sintomas geralmente consistem em prurido ocular ou periocular, lacrimejamento e olhos vermelhos que podem estar presentes durante todo o ano ou sazonalmente. A alergia ocular tem frequência elevada, é subdiagnosticada e pode ser debilitante para o paciente. É potencialmente danosa para a visão, nos casos em que ocasiona cicatrização corneana grave, e na maioria dos pacientes associa-se a outros quadros alérgicos, principalmente rinite, asma e dermatite atópica. É classificada em conjuntivite alérgica perene, conjuntivite alérgica sazonal, ceratoconjuntivite atópica e ceratoconjuntivite vernal. O diagnóstico procura evidenciar o agente etiológico e a confirmação se dá pela realização do teste de provocação conjuntival. O tratamento baseia-se em evitar o contato com os desencadeantes, lubrificação, anti-histamínicos tópicos, estabilizadores de mastócitos, imunossupressores e imunoterapia específica com o objetivo de obter o controle e prevenir as complicações da doença.


Ocular allergy, also known as allergic conjunctivitis, is an immunoglobulin E-mediated hypersensitivity reaction of the eye triggered by airborne allergens, primarily house dust mites and grass pollen. Symptoms usually consist of ocular or periocular itching, watery eyes, and red eyes that may be present year-round or seasonally. Ocular allergy has a high frequency, is underdiagnosed, and can be debilitating for the patient. It is potentially harmful to vision in cases of severe corneal scarring, and in most patients, it is associated with other allergic conditions, especially rhinitis, asthma, and atopic dermatitis. It is classified as perennial allergic conjunctivitis, seasonal allergic conjunctivitis, atopic keratoconjunctivitis, and vernal keratoconjunctivitis. Diagnosis seeks to identify the etiologic agent, and confirmation is given by conjunctival provocation testing. Treatment is based on avoiding contact with triggers, lubrication, topical antihistamines, mast cell stabilizers, immunosuppressants, and specific immunotherapy with the aim of achieving control and preventing disease complications.

ABSTRACT

Introdução: Mutações do gene da filagrina vêm sendo associadas, classicamente, a alterações da barreira epitelial em doenças alérgicas com comprometimento da pele e das superfícies mucosas. Particularmente na dermatite atópica, a relação entre filagrina, mecanismo fisiopatológico e evolução clínica tem sido demonstrada. Recentemente, alterações da barreira epitelial com redução da expressão da filagrina, também têm sido associadas a mecanismos imunológicos envolvidos na patogênese da esofagite eosinofílica. Devido a disfunções na barreira epitelial, microrganismos e alérgenos são capazes de penetrarem no epitélio da mucosa esofágica, assim como na dermatite atópica. Objetivo: Avaliar a possível correlação da expressão da filagrina com os achados histopatológicos em biópsias esofágicas de pacientes com esofagite eosinofílica. Métodos: A expressão da filagrina foi investigada in situ, por imuno-histoquímica, em biópsias esofágicas nos seguintes grupos: Grupo I, controle (n=8), amostras provenientes de pacientes saudáveis; Grupo II (n=27), amostras provenientes de pacientes com esofagite eosinofílica. Resultados: Os resultados demonstraram uma diminuição da expressão da filagrina na mucosa do esôfago de portadores de esofagite eosinofílica. Adicionalmente, a intensidade da marcação imuno-histoquímica foi menor na mucosa esofágica com maior infiltração de eosinófilos. Conclusão: A diminuição da expressão de filagrina pode ser um fenomeno fisiopatológico associado ao aumento da quantidade de eosinófilos na mucosa esofágica, podendo impactar na evolução clínica da esofagite eosinofílica.


Introduction:Filaggrin gene mutations have been classically associated with changes in the epithelial barrier in allergic diseases involving the skin and mucosal surfaces. Particularly in atopic dermatitis, the relationship between filaggrin, pathophysiological mechanism and clinical evolution hás been demonstrated. Recently, changes in the epithelial barrier with reduced expression of filaggrin have also been associated with immunological mechanisms involved in the pathogenesis of eosinophilic esophagitis. Due to dysfunction in the epithelial barrier, microorganisms and allergens are able to penetrate the epithelium of the esophageal mucosa, as well as in atopic dermatitis. Objective: To evaluated the possible correlation of filaggrin expression with histopathological findings in esophageal biopsies of patients with eosinophilic esophagitis. Methods: Filaggrin expression was investigated in situ by immunohistochemistry in esophageal biopsies in the following groups: Group I, control (n = 8), samples from healthy patients; Group II (n = 27), samples from patients with eosinophilic esophagitis. Results: The results demonstrated a decrease in the expression of filaggrin in the esophageal mucosa of patients with eosinophilic esophagitis. Additionally, the intensity of the immunohistochemical labeling was lower in the esophageal mucosa with greater infiltration of eosinophils. Conclusion: The reduction of filaggrin expression may be a pathophysiological phenomenon associated with an increase in the quantity of eosinophils in the esophageal mucosa, which may impact on the clinical evolution of eosinophilic esophagitis.

ABSTRACT

RESUMO: Introdução: O quadro da dermatite atópica (DA) é caracterizado por prurido crônico de evolução flutuante, que pode resultar em distúrbios no padrão de sono e em estigmatização social devido à presença de lesões visíveis e recidivantes, as quais tendem a se tornar progressivamente liquenificadas. Fatores como os já citados e outros associados, como incapacidade laboral, falta de concentração ao longo do dia e isolamento apresentam-se como profundos impactantes para a saúde mental do paciente, podendo resultar em baixa autoestima, depressão e frustração. Além disso, sabe-se que a DA é uma doença essencialmente inflamatória, ao mesmo tempo em que estudos recentes demonstram papel de citocinas no desenvolvimento de síndromes depressivas, podendo haver correlação causal entre os quadros por vias inflamatórias. Objetivos: Essa revisão sistemática de literatura objetivou analisar a relação entre dermatite atópica e sintomas depressivos, identificando possíveis mecanismos responsáveis por essa ligação. Métodos: A busca foi feita entre 17/11/2020 e 18/11/2020 seguindo o modelo PRISMA e utilizando as bases PUBMED, Biblioteca Virtual em Saúde (BVS) - IBECS, LILACS e CUMED - e EMBASE. As palavras-chave "Depression" e "Atopic Eczema", em conjunto com seus termos MeSh e DECS, foram utilizadas e associadas através do método booleano. Critérios para inclusão foram definidos como artigos que são ensaios clínicos ou observacionais envolvendo grupo de pacientes com dermatite atópica e grupo controle, que pôde ser constituído pelo próprio grupo com dermatite atópica, porém, após intervenção. Os sintomas depressivos precisavam ser medidos por escalas ou terem critérios para diagnóstico de síndrome depressiva estabelecidos. A seleção foi feita por todos os autores de forma independente, sendo discordâncias solucionadas por consenso. Resultados: Ao final, quinze estudos restaram, os quais foram classificados entre aqueles que comparam tratamentos e seus desfechos relacionados à depressão e DA, aqueles que propõem DA como agravante de sintomas depressivos, aqueles que propõem sintomas depressivos como agravantes da DA e aqueles que trazem análises estatísticas sem estabelecer claramente onde reside a relação de causalidade entre os dois quadros. Conclusões: Diversos estudos mostraram a existência de relação entre o quadro de DA e sintomas depressivos em vias distintas, tanto analisando a DA como agravante de sintomas depressivos como vice-versa. A partir dessa perspectiva, é possível que haja uma causalidade bidirecional cíclica, na qual um constante feedback positivo gera piora de ambos os quadros até que a abordagem adequada seja tomada, evidenciando a importância da propedêutica multidisciplinar para esses pacientes.(AU)


ABSTRACT: Introduction: Atopic dermatitis (AD) is characterized by chronic itching, presenting with fluctuating evolution, resulting in sleep disorders and social stigmatization due to the presence of visible and recurrent lesions, that might become progressively lichenified. Factors such as those mentioned and others associated, such as incapacity for work, lack of concentration throughout the day and isolation have profound impacts on the patient's mental health, resulting in low self-esteem, depression and frustration. In addition, it is known that AD is essentially an inflammatory disease. And, recent studies demonstrate the role of inflammatory cytokines in the development of depressive syndromes, therefore may be a causal correlation between the conditions by inflammatory pathways. Objectives: This systematic literature review aimed to analyze a relationship between atopic dermatitis and depressive symptoms, identifying mechanisms responsible for this connection. Methods: The research was carried out between 11/17/2020 and 11/18/2020 following the PRISMA model and using PUBMED, Virtual Health Library (VHL) - IBECS, LILACS and CUMED - and EMBASE databases. Keywords "Depression" and "Atopic Eczema", along with its MeSh and DECS terms, were used and associated using the Boolean method. Inclusion criteria were defined as articles that are clinical or observational trials involving a group of patients with atopic dermatitis and a control group, which could be constituted by the group with atopic dermatitis itself, however, after an intervention. The depressive symptoms had to be measured by scales or, at least, the criteria for diagnosis of depressed syndrome must have been established. Results:In the end, fifteen studies remained, which were classified among those that compare treatments and their outcomes related to depression and AD, those that propose AD as an aggravator of depressive symptoms, those that propose depressive symptoms as an aggravating factor for AD and those that bring statistical analysis without clearly establishing where the causality relation resides. Conclusion: Several studies have presented a relationship between the condition of AD and depressive symptoms in distinct pathways, or analyzing AD as an aggravating factor for depressive symptoms or vice-versa. From this perspective, there may be a cyclical bidirectional causality, in which constant positive feedback generates worsening of both conditions until the adequate approach is taken, highlighting the importance of the multidisciplinary propaedeutics for these patients.

ABSTRACT

Acupoint autohemotherapy at bilateral Zusanli (ST36) and Xuehai (SP10) was used to treat a 26-year-old female patient who had suffered from recalcitrant atopic eczema (AE) for five years. The treatment was applied at a frequency of once per week for the first month, followed by a three-month period of once every other week. At the end of treatment, the patient's AE symptoms were entirely resolved, and by the end of a six-month follow-up her immunoglobulin E level had returned to the normal range. Further, there was no relapse of AE symptoms during the six-month follow-up. Therefore, we hypothesized that after the repeated treatments the local inflammatory reaction induced by autologous blood injection triggered a local immune response, followed by a systemic immune response after the repeated treatment, finally leading to the anti-inflammation and immunomodulation effects. This case suggests that acupoint autohemotherapy could be used as an effective complementary treatment for recalcitrant AE, especially in cases where other treatments have failed. Further comparative studies are needed to corroborate the value and mechanisms of this therapy.
