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.

Objective: The optimal use of drug combinations for the management of asthma is providing significant results. This has prompted Interasma (Global Asthma Association) to take a position on inhaled triple therapy in asthma.Methods: We performed an extensive literature research to clinical trials, meta-analyses, randomized controlled trials and systematic reviews.Results: Starting from an extensive literature review, Interasma executive committee discussed and approved this Manifesto, developed by Interasma scientific network (INES) members.Conclusions: The manifesto describes the evidence gathered to date and states, advocates, and proposes issues on inhaled corticosteroid (ICS) plus long-acting beta 2 agonist (LABA) and long-acting muscarinic antagonists (LAMA) with the aim of challenging assumptions, fostering commitment, and bringing about change.

OBJECTIVES: Atopic dermatitis (AD) is the most prevalent chronic inflammatory skin disease, with a vast drug arsenal and guidelines available for its management and diagnosis and different medical specialties engaged in providing care. This study aimed to outline the therapeutic and diagnostic approaches to the AD of allergists, dermatologists, and pediatricians and verify whether they are compliant with the guidelines. METHODS: A cross-sectional study using an electronic questionnaire administered through the SurveyMonkey® platform was disclosed by participating medical societies to their medical associates. RESULTS: Of the 1,473 participating physicians, the use of moisturizers as part of AD treatment was observed among pediatricians (91.9%), dermatologists (97.5%), and allergists (100%; p=0.07). The preference for the use of new emollients was lower among pediatricians (57%) than dermatologists (75.9%) and allergists (71.4%; p < 0.001). The prevalence of wet-wrap therapy was lower among dermatologists (16.3%) than allergists (51%; p < 0.001). The recommendation of proactive treatment with topical corticosteroids was more frequently reported by allergists (65.3%) than pediatricians (43.3%) and dermatologists (40.8%; p < 0.001), and the same trend was observed in relation to proactive treatment using calcineurin inhibitors. The use of oral anti-histamines to control pruritus was mainly considered by pediatricians (69.2%) and dermatologists (59.2% p < 0.001). Clinical experience with systemic immunomodulating agents was greater among allergists (77.5%) and dermatologists (60.8%; p < 0.001), with cyclosporine being the most cited systemic immunomodulating agent. Environmental control of aeroallergens was recommended by pediatricians (89.8%), dermatologists (86.9%), and allergists (100%; p=0.01). CONCLUSION: There were differences in the therapeutic and diagnostic approaches to AD used by allergists, dermatologists, and pediatricians and those recommended by the guidelines, especially regarding the use of wet-wrap therapy, proactive treatment with topical corticosteroids or calcineurin inhibitors, prescription of anti-histamines, recommendation of phototherapy, and control of aeroallergens.
ABSTRACT
The impact of climate change on the environment, biosphere, and biodiversity has become more evident in the recent years. Human activities have increased atmospheric concentrations of carbon dioxide (CO2 ) and other greenhouse gases. Change in climate and the correlated global warming affects the quantity, intensity, and frequency of precipitation type as well as the frequency of extreme events such as heat waves, droughts, thunderstorms, floods, and hurricanes. Respiratory health can be particularly affected by climate change, which contributes to the development of allergic respiratory diseases and asthma. Pollen and mold allergens are able to trigger the release of pro-inflammatory and immunomodulatory mediators that accelerate the onset the IgE-mediated sensitization and of allergy. Allergy to pollen and pollen season at its beginning, in duration and intensity are altered by climate change. Studies showed that plants exhibit enhanced photosynthesis and reproductive effects and produce more pollen as a response to high atmospheric levels of carbon dioxide (CO2 ). Mold proliferation is increased by floods and rainy storms are responsible for severe asthma. Pollen and mold allergy is generally used to evaluate the interrelation between air pollution and allergic respiratory diseases, such as rhinitis and asthma. Thunderstorms during pollen seasons can cause exacerbation of respiratory allergy and asthma in patients with hay fever. A similar phenomenon is observed for molds. Measures to reduce greenhouse gas emissions can have positive health benefits.
