Correlation between disease severity indices and quality of life measurement tools in atopic dermatitis patients / Correlación entre los índices de gravedad de la enfermedad y las herramientas de medición de la calidad de vida en pacientes con dermatitis atópica

INTRODUCTION: Reports regarding the correlation and effect size of change of the full spectrum of quality of life and disease severity measures applied in-person to patients with atopic dermatitis are scarce. OBJECTIVES: To assess quality-of-life with 3 different instruments and to evaluate disease severity indices and to determine their correlation and effect size of change between two measurements. MATERIALS AND METHODS: Patient-level data were obtained through two in-person visits. Sociodemographic information and data related to disease distribution, severity (through the BSA, EASI, SCORAD, POEM, and itching scales), and the impact of atopic dermatitis on quality of life using the DLQI and Skindex-29, and EQ-5D, were assessed. The correlation between change in quality-of-life scores and disease severity scores in addition to the standardized effect size were also evaluated. RESULTS: Only 139 out of 212 patients completed the follow-up visit. BSA highly correlated with SCORAD and EASI, and the lowest correlation was found with POEM. The best correlation of pruritus VAS was found with sleep disturbance. The SCORAD score highly correlated with EASI, and the lowest correlation was found with POEM. The magnitude of the effect at initiation of the study vs follow-up was in average moderate to important. CONCLUSIONS: Patients with atopic dermatitis experience a substantial burden on quality of life. Disease activity correlates better with quality-of-life measurements when the disease is less severe after starting therapy. POEM and Skindex-29 seem to be optimal to determine disease severity and quality of life in adults with atopic dermatitis.

Introducción: La información publicada sobre la correlación entre la magnitud del efecto de todo el espectro de la calidad de vida y la gravedad de la enfermedad en pacientes con dermatitis atópica es escasa. Objetivos: Evaluar la calidad de vida con tres instrumentos diferentes y los índices de gravedad de la enfermedad en pacientes con dermatitis atópica para determinar su correlación y el tamaño del efecto del cambio. Materiales y métodos: Los datos de los pacientes se obtuvieron a partir de dos visitas. Se evaluó la información sociodemográfica y los datos relacionados con la distribución y la gravedad de la enfermedad (mediante de las escalas BSA, EASI, SCORAD, POEM, prurito) y el impacto de la dermatitis atópica en la calidad de vida utilizando el Dermatology Life Quality Index, Skindex-29 y EQ-5D. También se evaluó la correlación entre el cambio en las puntuaciones de calidad de vida y las de gravedad de la enfermedad, además del tamaño del efecto estandarizado. Resultados: Solo 139 de los 212 pacientes completaron la visita de seguimiento. El área de superficie corporal se correlacionó fuertemente con el SCORAD y el EASI, y la correlación más débil fue con el POEM. La mejor correlación del prurito medido con la escala visual análoga se halló con la alteración del sueño. El puntaje SCORAD se correlacionó altamente con el EASI mientras que la correlación más baja se encontró con el POEM. La magnitud del efecto al inicio del estudio respecto al seguimiento fue en promedio de moderada a importante. Conclusiones: Los pacientes con dermatitis atópica experimentan una carga sustancial en la calidad de vida. La actividad de la enfermedad se correlaciona mejor con las mediciones de calidad de vida cuando esta es menos grave, después de comenzar la terapia. Los índices POEM y Skindex-29 parecen ser óptimos para determinar la gravedad de la enfermedad y la calidad de vida en adultos con dermatitis atópica.

Collective Re-Storying of Mentee and Mentor Experiences in a Cancer Research Education Program for American Indian and Alaska Native Students.

The Youth Enjoy Science program at the University of Nebraska Medical Center has engaged American Indian/Alaska Native youth in mentored cancer research internships from 2017 to 2022. The primary purpose of this study was to examine mentor and mentee lived experiences of participation in Youth Enjoy Science research education internships and to provide insights that can inform mentorship practices in research education programs for American Indians/Alaska Natives. We conducted semi-structured interviews with current and former Youth Enjoy Science mentees (n=8) and mentors (n=8). Following a narrative inquiry research approach, we analyzed interview transcripts and collectively re-storied interview data. Participants described program characters, settings, problems, actions to address the problems identified, and resolutions that led to various recommendations for ways to raise contextual awareness between mentees and mentors.

Epidemiologic features and burden of atopic dermatitis in adolescent and adult patients: A cross-sectional multicenter study.

BACKGROUND: Atopic dermatitis (AD) is considered as one of the most frequent chronic skin conditions. Previous AD epidemiologic studies have been mainly retrospective and/or have been performed through surveys instead of in-person visits. Epidemiological studies concerning AD in Latin American countries are scarce. OBJECTIVE: To describe sociodemographic and clinical features and the economic burden of AD on children and adult patients in Colombia through in-person visits. METHODS: This was a cross-sectional study of 212 patients that included sociodemographic and clinimetric data. The diagnostic criteria of Hanifin and Rajka was used and data relating to disease distribution, disease severity (through the BSA: Body surface area; EASI: Eczema Area and Severity Index; SCORAD: Scoring Atopic Dermatitis), Fitzpatrick's skin phototypes, personal and familiar history of allergic diseases, previous treatments, and personal history of comorbidities, was collected. RESULTS: Patient age range was 12-76, and 52.8% were female. Disease distribution was mainly flexural (19.6%). Early age start, Denni-Morgan fold, and infections tendency were more frequent in adolescents compared to adults. Mean age of diagnosis was 12 years old, AD diagnosis was made mostly by a dermatologist, 48.1% (102 patients) reported alcohol consumption, and 59% of consumers were heavy drinkers. Comorbidities found were: chronic rhinitis (68.9%) food allergy (32.5%), allergic conjunctivitis (29.7%), and asthma (28.8%). Around 81% earned less than $896 US dollars and 59% invested 6-30% of their monthly budget yearly, and 40% had work or school absenteeism. Mean scores of BSA, EASI, and SCORAD involvement were 32.6, 13.7, and 42.4, respectively. CONCLUSIONS: This study adds well-supported data through an in-depth clinical and economical characterization of Colombian adolescents and adult patients with atopic dermatitis and shows its high impact and burden on patients and their families. It also contributes to understand the burden of AD in Latin America.

Atopic dermatitis in the COVID-19 era: Results from a web-based survey.

Given that the COVID-19 era has changed the behavior of all individuals, and since previous reports about its possible impact on atopic dermatitis (AD) patients remained speculative, in this survey we aimed to explore the real impact of COVID-19 among AD patients. All participants provided verbal consent prior to completing the survey. A 37-question web-based survey with no personal identifiers was sent to 212 previously identified AD patients. Itching, sleep disturbances, SARS-CoV-2, illness cost, economic dependence, monthly income, and monthly investment in AD before and during the pandemic, were all included in the analysis. A response rate of 73.1% was obtained. The mean age of participants was 30 years-old, and 57% were women. Around 75% reported AD worsening, and 59.4% of the patients reported sleep problems. Uncertainty, anxiety, and pessimism were frequent during the pandemic. Only 1.3% tested positive for SARS-CoV-2, and it was only significantly associated with comorbidities (p=0.03; Chi2 Test). A significant difference was found in economic dependence and monthly income when compared between before and during the pandemic. This study provides probably the best possible assessment of the clinical, social, and economic effects of the pandemic on patients with an already proven diagnosis of AD.

Talidomida como inmunomodulador / Talidomide as immunomoludator

La eficacia de la talidomida en el tratamiento de diferentes trastornos inflamatorios y autoinmunes parece deberse a su efecto inmunomodulador y antiinflamatorio. Además, puede aumentar el efecto antitumoral de algunos agentes usados para el tratamiento de las neoplasias. La talidomida se ha usado con éxito en enfermedades como: eritema nodoso leproso, estomatitis aftosa recurrente, enfermedad de injerto contra hospedero, lupus eritematoso sistémico, y recientemente ha sido aprobada por la FDA para el tratamiento de las úlceras aftosas relacionadas con la infección por el VIH. El efecto adverso más severo es la teratogenicidad, siendo las focomelias o amelias las malformaciones más comunes. Por ello, toda mujer en edad reproductiva debe ser informada acerca de los riesgos de tomar este medicamento

Inflamacion minima persistente / Persistent minimun inflamation

Los individuos predispuestos genéticamente a desencadenar reacciones alérgicas luego del contacto con diferentes antígenos, principalmente estacionales, no muestran un infiltrado inflamatorio o expresión de la molécula ICAM-1 sobre diferentes órganos blancos cuando no han sido previamente sensibilizados. Sin embargo, si estos individuos son expuestos a los alergenos que previamente los habían sensibilizado, se presenta un infiltrado celular característico y la expresión del ICAM-1 sobre las células epiteliales, fenómenos que están estrictamente relacionados con la exposición alergénica y que no desaparecen definitivamente en los períodos libres de síntomas. El hecho de que estos marcadores histológicos de la inflamación existan en ausencia de sintomatología es muy importante, y este fenómeno ha sido llamado inflamación mínima persistente (IMP)
