Pollen sensitization among Egyptian patients with respiratory allergic diseases.

Pollen is responsible for seasonal allergies, such as allergic rhino-conjunctivitis (AR), and has become a growing public health concern. Climate change affects the range of allergenic species as well as the timing and length of the pollen season. In Egypt, data on pollinosis are scarce.

Prevalence of work-related asthma among Egyptian farmers in Great Cairo.

Work related asthma (WRA) refers to asthma induced by exposure to sensitizing agents and/or irritants in the workplace leaving health and economic consequences. Early diagnosis can improve the prognosis of WRA permitting sometimes full recovery. This study aimed to assess the prevalence of WRA among Egyptian adult agriculture workers.

Comparison of COVID-19 characteristics in Egyptian patients according to their Toll-Like Receptor-4 (Asp299Gly) polymorphism.

Background: Toll-like receptor (TLR)-4 plays a vital role in recognizing viral particles, activating the innate immune system, and producing pro-inflammatory cytokines.

Objectives: This cross-sectional study aimed to compare COVID-19 severity, progression, and fate according to TLR-4 (Asp299Gly) polymorphism in Egyptian patients.

Methods: A total of 145 COVID-19 patients were included in this study.

Prevalence of confirmed immunoglobulin E-mediated food allergy among adult Egyptian patients.

Food allergy (FA) represents an increasing social and economic health problem. Prevalence of food allergy differs from one country to another depending on genetic and environmental as well as feeding habits of each country. Estimate the prevalence of confirmed immunoglobulin E-mediated food allergy (FA) among adult Egyptian patients and identify its possible risk factors.
