RESUMO

BACKGROUND: Information/communication technologies such as mobile phone applications (apps) would enable chronic urticaria (CU) patients to self-evaluate their disease activity and control. Yet, recently Antó et al (2021) reported a global paucity of such apps for patients with CU. In this analysis, we assessed patient interest in using apps to monitor CU disease activity and control using questions from the chronic urticaria information and communication technologies (CURICT) study. METHODS: The methodology for CURICT has been reported. Briefly, a 23-item questionnaire was completed by 1841 CU patients from 17 UCAREs across 17 countries. Here, we analyzed patient responses to the CURICT questions on the use of apps for urticaria-related purposes. RESULTS: As previously published, the majority of respondents had chronic spontaneous urticaria (CSU; 63%; 18% chronic inducible urticaria (CIndU) [CIndu]; 19% with both), were female (70%) and in urban areas (75%). Over half of patients were very/extremely interested in an app to monitor disease activity (51%) and control (53%), while only ∼1/10 were not. Patients with both urticaria types versus those with CSU only (odds ratio [OR], 1.36 [1.03-1.79]) and females versus males (OR [95% CI], 1.47 [1.17-1.85]) were more likely to be very to extremely interested in an app to assess disease control. CONCLUSIONS: Overall, half of the patients with CU were very to extremely interested in using an app to assess their disease activity and control. Development of well-designed apps, specific to disease types (CSU, CIndU, CSU + CIndU, etc), validated by experts across platforms would help improve the management and possibly outcomes of CU treatment while providing important patient information to be used in future research.

RESUMO

The prevalence of food allergy has increased over the last 20-30 years, including cow milk allergy (CMA) which is one of the most common causes of infant food allergy. International allergy experts met in 2019 to discuss broad topics in allergy prevention and management of CMA including current challenges and future opportunities. The highlights of the meeting combined with recently published developments are presented here. Primary prevention of CMA should start from pre-pregnancy with a focus on a healthy lifestyle and food diversity to ensure adequate transfer of inhibitory IgG- allergen immune complexes across the placenta especially in mothers with a history of allergic diseases and planned c-section delivery. For non-breastfed infants, there is controversy about the preventive role of partially hydrolyzed formulae (pHF) despite some evidence of health economic benefits among those with a family history of allergy. Clinical management of CMA consists of secondary prevention with a focus on the development of early oral tolerance. The use of extensive Hydrolysate Formulae (eHF) is the nutrition of choice for the majority of non-breastfed infants with CMA; potentially with pre-, probiotics and LCPUFA to support early oral tolerance induction. Future opportunities are, among others, pre- and probiotics supplementation for mothers and high-risk infants for the primary prevention of CMA. A controlled prospective study implementing a step-down milk formulae ladder with various degrees of hydrolysate is proposed for food challenges and early development of oral tolerance. This provides a more precise gradation of milk protein exposure than those currently recommended.

RESUMO

BACKGROUND: Patients with chronic urticaria (CU) are increasingly using information and communication technologies (ICTs) to manage their health. What CU patients expect from ICTs and which ICTs they prefer remains unknown. We assessed why CU patients use ICTs, which ones they prefer, and what drives their expectations and choices. METHODS: In this cross-sectional study, 1841 patients across 17 countries were recruited at UCAREs (Urticaria Centers of Reference and Excellence). Patients with CU who were >12 years old completed a 23-item questionnaire. RESULTS: Most patients were interested in receiving disease information (87.3%), asking physicians about CU (84.1%), and communicating with other patients through ICTs (65.6%). For receiving disease information, patients preferred one-to-one and one-to-many ICTs, especially web browsers. One-to-one ICTs were also the ICTs of choice for asking physicians about urticaria and for communicating with other patients, and e-mail and WhatsApp were the preferred ICTs, respectively. Many-to-many ICTs such as Facebook, Instagram, LinkedIn, and Twitter were least preferred for all 3 purposes. Living in rural areas and higher education were linked to higher odds of being interested in receiving disease information, asking physicians, and communicating with patients through ICTs. CONCLUSIONS: Most patients and especially patients with higher education who live in rural areas are interested in using ICTs for their healthcare, but prefer different ICTs for different purposes, ie, web browsers for obtaining information, e-mail for asking physicians, and WhatsApp for communicating with other patients. Our findings may help to improve ICTs for CU.

RESUMO

Respiratory viral infections have been implicated in the origin and exacerbation of asthma symptoms in a variety of ways. A growing body of evidence indicates that viral infections are closely linked to infantile wheezing and suggest that severe bronchiolitis in early infancy may predispose to chronic childhood asthma. Alternatively, it could represent a marker of susceptible individuals. In contrast, mild repetitive infections in early years may provide a protective role against the development of asthma or atopy by switching the immune system towards Th1 responses. However, evidence on this hypothesis is not consistent as far as viruses are concerned. On the other hand, in the presence of asthma, the role of viral infections on exacerbations is well established. Several factors, such as the presence of atopy, timing of the exposure and severity of the infections, interactively contribute to the asthma-infection relationship. In the present report, recent data on the involvement of viral infections in the development and progression of asthma are reviewed

Las infecciones virales respiratorias han sido involucradas en el origen y en las exacerbaciones de los síntomas del asma en una variedad de formas. Cada vez hay más indicios de que las infecciones virales están estrechamente relacionadas con sibilancias en la niñez y sugieren que la bronquiolitis grave en la primera infancia puede predisponer a asma crónica infantil; por otra parte, podría representar un marcador de individuos susceptibles. Por el contrario, las infecciones leves repetidas en los primeros años brindarían un efecto protector contra la aparición de asma o atopia mediante la desviación del sistema inmunitario hacia respuestas Th1. Sin embargo, la información relacionada con esta hipótesis no es firme en lo que a virus se refiere. Por otra parte, en presencia de asma, el papel de las infecciones virales sobre las exacerbaciones está bien establecido. Varios factores, como la presencia de atopia, el momento en el que se produce la exposición y la gravedad de las infecciones, interactúan en la relación entre asma e infección. En este artículo se revisan datos acerca de la participación de las infecciones virales en la aparición y progresión del asma
