Anaphylaxis Associated with Peanuts and Nuts in Late Mexican Adolescents: A Population Based Study

Background: There is a lack of information regarding anaphylaxis that is triggered by the peanut and nuts in countries with emerging economies. We aimed to identify the factors that are related to the prevalence of secondary anaphylaxis that results from ingesting peanuts or nuts. Materials and Methods: A cross-sectional, population-based study was conducted in which we applied a structured questionnaire to a random sample of 1992 adolescents, aged 15 to 18 years. After identifying those subjects with presence of adverse symptoms after food intake, we then asked if this was due to the ingestion of the peanuts or nuts. Factors associated with anaphylaxis were identified through the odds ratio estimation using logistic regression in a multivariate analysis model. Results: The prevalence of global anaphylaxis caused by the peanuts and nuts was 0.9%, n=17 (95% CI: 0.5% to 1.4%); 0.6%, n=12 (95% CI: 0.3% to 1.1%) with any type of nut, and 0.3%, n=7 (95% CI: 0.2% to 0.7%) with the peanut; anaphylaxis caused exclusively by the peanut was recorded at 0.2% (95% CI: 0.1% to 0.6%). Notably, one case of anaphylaxis was triggered by five types of nuts (almond, pecan, Brazilian nut, cashew, and pistachio), another by 4 types (hazelnut, peanut, walnut, pecan, and cashew), there were 9 cases that were prompted by only one food (5 peanut, 2 cashew, 1 chestnut, 1 almond). The only factor found to be associated with anaphylaxis was a personal history of pollen allergy, odds ratio: 10.12 (p = 0.046). Conclusion: The prevalence of anaphylaxis induced by peanuts or nuts in the Mexican population varies from 0.5 to 1.4%; and the personal history of pollen allergy was the only associated factor with anaphylaxis

Self-report prevalence and associated factors to drug hypersensitivity in Mexican young adults

Background: Drug hypersensitivity is defined as any unfavorable reaction that occurs after the administration of any drug. It may or may not be mediated by the involvement of the immune system. Epidemiological data related to drug hypersensitivity reactions in our country are scarce. Objective: To determine the prevalence of drug hypersensitivity in a group of young adults, as well as to identify associated factors. Methods: A structured questionnaire was applied to young people aged 18 to 25 years. The instrument was oriented to identify reactions of drug hypersensitivity, as well as the most prevalent drugs involved. In addition, a personal and family history of atopic diseases was included. Analysis for associations between variables was been done through logistic regression. Results: The prevalence of drug hypersensitivity reactions was 12% (144 of 1,200). The antibiotics were the agents most related to hypersensitivity reactions (9.8%) followed by nonsteroidal anti-inflammatory drugs (1.6%). Factors associated with drug hypersensitivity were a personal history of asthma, odds ratio (OR) 3.15 (95% confidence interval [CI], 1.44–6.91), maternal and paternal history of drug hypersensitivity, OR 2.33 (95% CI, 1.21–4.48) and OR 3.11 (95% CI, 1.22–7.92), respectively. Conclusion: The results of this research show that drug hypersensitivity in young adults is a highly prevalent event and it is associated with personal history of asthma and history of drug hypersensitivity in parents

Cabbage and fermented vegetables : From death rate heterogeneity in countries to candidates for mitigation strategies of severe COVID-19

Large differences in COVID-19 death rates exist between countries and between regions of the same country. Some very low death rate countries such as Eastern Asia, Central Europe, or the Balkans have a common feature of eating large quantities of fermented foods. Although biases exist when examining ecological studies, fermented vegetables or cabbage have been associated with low death rates in European countries. SARS-CoV-2 binds to its receptor, the angiotensin-converting enzyme 2 (ACE2). As a result of SARS-CoV-2 binding, ACE2 downregulation enhances the angiotensin II receptor type 1 (AT(1)R) axis associated with oxidative stress. This leads to insulin resistance as well as lung and endothelial damage, two severe outcomes of COVID-19. The nuclear factor (erythroid-derived 2)-like 2 (Nrf2) is the most potent antioxidant in humans and can block in particular the AT(1)R axis. Cabbage contains precursors of sulforaphane, the most active natural activator of Nrf2. Fermented vegetables contain many lactobacilli, which are also potent Nrf2 activators. Three examples are: kimchi in Korea, westernized foods, and the slum paradox. It is proposed that fermented cabbage is a proof-of-concept of dietary manipulations that may enhance Nrf2-associated antioxidant effects, helpful in mitigating COVID-19 severity.Peer reviewe

Nrf2-interacting nutrients and COVID-19 : time for research to develop adaptation strategies

There are large between- and within-country variations in COVID-19 death rates. Some very low death rate settings such as Eastern Asia, Central Europe, the Balkans and Africa have a common feature of eating large quantities of fermented foods whose intake is associated with the activation of the Nrf2 (Nuclear factor (erythroid-derived 2)-like 2) anti-oxidant transcription factor. There are many Nrf2-interacting nutrients (berberine, curcumin, epigallocatechin gallate, genistein, quercetin, resveratrol, sulforaphane) that all act similarly to reduce insulin resistance, endothelial damage, lung injury and cytokine storm. They also act on the same mechanisms (mTOR: Mammalian target of rapamycin, PPAR gamma:Peroxisome proliferator-activated receptor, NF kappa B: Nuclear factor kappa B, ERK: Extracellular signal-regulated kinases and eIF2 alpha:Elongation initiation factor 2 alpha). They may as a result be important in mitigating the severity of COVID-19, acting through the endoplasmic reticulum stress or ACE-Angiotensin-II-AT(1)R axis (AT(1)R) pathway. Many Nrf2-interacting nutrients are also interacting with TRPA1 and/or TRPV1. Interestingly, geographical areas with very low COVID-19 mortality are those with the lowest prevalence of obesity (Sub-Saharan Africa and Asia). It is tempting to propose that Nrf2-interacting foods and nutrients can re-balance insulin resistance and have a significant effect on COVID-19 severity. It is therefore possible that the intake of these foods may restore an optimal natural balance for the Nrf2 pathway and may be of interest in the mitigation of COVID-19 severity

Allergic Rhinitis and its Impact on Asthma (ARIA) Phase 4 (2018) : Change management in allergic rhinitis and asthma multimorbidity using mobile technology

Allergic Rhinitis and its Impact on Asthma (ARIA) has evolved from a guideline by using the best approach to integrated care pathways using mobile technology in patients with allergic rhinitis (AR) and asthma multimorbidity. The proposed next phase of ARIA is change management, with the aim of providing an active and healthy life to patients with rhinitis and to those with asthma multimorbidity across the lifecycle irrespective of their sex or socioeconomic status to reduce health and social inequities incurred by the disease. ARIA has followed the 8-step model of Kotter to assess and implement the effect of rhinitis on asthma multimorbidity and to propose multimorbid guidelines. A second change management strategy is proposed by ARIA Phase 4 to increase self-medication and shared decision making in rhinitis and asthma multimorbidity. An innovation of ARIA has been the development and validation of information technology evidence-based tools (Mobile Airways Sentinel Network [MASK]) that can inform patient decisions on the basis of a self-care plan proposed by the health care professional.Peer reviewe

In the (sub)tropics Allergic Rhinitis and Its Impact on Asthma classification of allergic rhinitis is more useful than perennial-seasonal classification

Background: Two different allergic rhinitis (AR) symptom phenotype classifications exist. Treatment recommendations are based on intermittent-persistent (INT-PER) cataloging, but clinical trials still use the former seasonal AR-perennial AR (SAR-PAR) classification. This study was designed to describe how INT-PER, mild-moderate/severe and SAR-PAR of patients seen by allergists are distributed over the different climate zones in a (sub) tropical country and how these phenotypes relate to allergen sensitization patterns. Methods: Six climate zones throughout Mexico were determined, based on National Geographic Institute (Instituto Nacional de Estadistica y Geografia) data. Subsequent AR patients (2-68 years old) underwent a blinded, standardized skin-prick test and filled out a validated questionnaire phenotyping AR. Results: Five hundred twenty-nine subjects participated in this study. In the tropical zone with 87% house-dust mite sensitization, INT (80.9%; p < 0.001) and PAR (91%; p = 0.04) were more frequent than in the subtropics. In the central high-pollen areas, there was less moderate/severe AR (65.5%; p < 0.005). Frequency of comorbid asthma showed a clear north-south gradient, from 25% in the dry north to 59% in the tropics (p < 0.005). No differences exist in AR cataloging among patients with different sensitization patterns, with two minor exceptions (more PER in tree sensitized and more PAR in mold positives; p < 0.05). Conclusion: In a (sub) tropical country the SAR-PAR classification seems of limited value and bears poor relation with the INT-PER classification. INT is more frequent in the tropical zone. Because PER has been shown to relate to AR severity, clinical trials should select patients based on INT-PER combined with the severity cataloging because these make for a better treatment guide than SAR-PAR

MASK (Mobile Airways Sentinel Network). ARIA’s comprehensive solution for mobile app for the multimorbidity of allergic rhinitis and asthma

International audienceThe vast majority of patients with allergic rhinitis (AR) do not receive the proper management which is recommended by the guidelines, but they frequently self-medicate. MASK (Mobile Airways Sentinel Network) is an integral part of a project that is supported by the European Union againstchronic diseases and focused on active and healthy aging. MASK represents the third phase of ARIA (Allergic Rhinitis and its Impact on Asthma), in which, by using a mobile application in a smart device, the objective is to guide the patient in the control of his/her multi-morbidity, AR and/or allergic conjunctivitis (AC) and/or asthma. The mobile app Allergy Diary by MACVIA-ARIA is free and it is available for both Android and iOS platforms. After it is downloaded to the patient’s cell phone, it fi rst requests some information about the patient’s profi le, allergic pathologies and medication; afterwards, through a visual analog scale, the patient is invited to determine the degree of affectation in the nose, eyes, and bronchi, and its influence on their productivity at work / school. After analyzing the data generated by fi lling the Allergy Diary, it became clear there is a new clinical entity: allergic rhinitis+ allergic conjunctivitis +asthma, with greater effect; in addition to a high level of self-medication: in general, the patient takes medication on days when symptoms are present. The app has already been deployed in 23 countries, including several Spanish-speaking countries.La mayor\'ia de los pacientes con rinitis alérgica no recibe el manejo idóneo, sino que se automedica. MASK (Mobile Airways Sentinel Network) forma parte integral de un proyecto apoyado por la Unión Europea contra las enfermedades crónicas y enfocado al envejecimiento activo y saludable. Constituye la tercera fase de ARIA (Allergic Rhinitis and its Impact on Asthma), en la cual mediante una aplicación móvil en un dispositivo inteligente se intenta guiar al paciente en el control de su multimorbilidad, rinitis o conjuntivitis alérgicas o asma. La aplicación Diario de Alergia por MACVIA-ARIA es gratuita y está disponible para Android e iOS. Al descargarla al celular del paciente, a este se le piden datos de su perfil, patolog\'ias alérgicas y medicación; posteriormente, mediante una escala visual analógica se le invita a determinar el grado de afectación en nariz, ojos y bronquios y su influencia sobre su productividad laboral/escolar. Con los datos del Diario de Alergia se observa que existe un nuevo patrón de presentación: rinitis alérgica + conjuntivitis alérgica + asma, con mayor afectación, as\'i como un alto nivel de automedicación: en general, el paciente toma medicación cuando presenta s\'intomas. La app se ha desplegado en 23 pa\'ises, incluyendo varios pa\'ises hispanohablantes
