introduction:the prevalence of atopic diseases has increased in recent decades dramatically. the most common aeroallergens in northeastern iran have not been fully defined. define the most common aeroallergens in allergic patients based on the skin prick test (spt) was aimed in this investigation.materials and methods:this cross-sectional study enrolled 1,006 allergic patients (aged 1–86 years)...

allergic rhinitis (ar) is one of the most common allergic disorders of child¬hood. in order to determine the frequency of ar among school-age children, a cross-sectional study was performed. one thousand, nine hundred and thirty-two children (931 boys and 1001 girls), aged 7-18 years, from 30 systematic randomly selected schools of tehran, the capital of iran, were investigated in this study. s...

Allergic conjunctivitis affects approximately 15% of the global population and has a higher prevalence of about 40% in industrialized countries such as the United States. Seasonal allergy sufferers present with a variety of signs and symptoms, but patients frequently report that ocular allergy symptoms are the most bothersome. Many topical ocular prescription therapies are available and are inc...

BACKGROUND Alteration of the gut microbial population (dysbiosis) may increase the risk for allergies and other conditions. This study sought to clarify the relationship of dysbiosis with allergies in adults. METHODS Publicly available American Gut Project questionnaire and fecal 16S rRNA sequence data were analyzed. Fecal microbiota richness (number of observed species) and composition (UniF...

Two hundred and fifty six attacks of acute bronchial asthma occurring in 169 children aged over 2 years were studied during a two year period. More attacks occurred during spring and autumn than at other times of the year. In 73 patients (29%) a respiratory virus infection was diagnosed, with the same seasonal variation as the asthmatic attacks. Most of the virus infections were caused by rhino...

PURPOSE We previously demonstrated seasonal variation in sensitization to aeroallergens in a small group of patients with exercise-induced asthma. This study was performed to confirm the relationship in a much larger population. METHODS The charts of 1,891 patients who received allergy skin prick tests were reviewed retrospectively. The test results from subjects aged ≤60 years were compared ...

BACKGROUND Recent studies suggest a possible role for low ultraviolet radiation exposure and low vitamin D status as a risk factor for food allergy. We hypothesized that children born in autumn/winter months (less sun exposure) might have higher food allergy rates than those born in spring/summer. METHODS We compared IgE-mediated food allergy rates by season of birth in 835 children aged 0-4 ...

Australia was alerted to a possible increase in allergy-related adverse events following immunisation (AEFI) with 2015 seasonal trivalent influenza vaccines (TIV) by the Victorian state vaccine safety service, SAEFVIC. We describe SAEFVIC's initial investigation and upon conclusion of the 2015 influenza vaccination programme, to define the signal event and implications for vaccine programmes. A...

Ocular allergy represents one of the most common conditions encountered by allergists and ophthalmologists. Allergic conjunctivitis is often underdiagnosed and consequently undertreated. Basic and clinical research has provided a better understanding of the cells, mediators, and immunologic events, which occur in ocular allergy. New pharmacological agents have improved the efficacy and safety o...
