Allergies and anaphylactic shock: why and how
Allergic diseases are a significant health and social problem due to their high frequency in the population and, as for anaphylactic shock (fortunately rarer) also due to seriousness. We are talking about: atopic dermatitis, allergic rhino-conjunctivitis, allergic bronchial asthma, gastrointestinal allergies and anaphylactic shock. Consequence of an anomalous response of the immune system to elements such as pollens, house dust mites, epidermic derivatives of pets, some foods and drugs, which are normally harmless for most people, these allergic diseases are caused by a combination of genetic and environmental factors that may trigger a local or even systemic inflammatory reaction. Allergic diseases have notably increased in the last decades, most probably because of the improved hygiene conditions that have led to a reduction in the microbial load in the fetal and neonatal period and, therefore, caused a change in the immune system response modes.
