Abstract:
The excessive, often unconfirmed suspicions of beta-lactam allergy affect up to 10% of the general population, improperly denying a significant percentage of individuals the opportunity to be treated with first-line antibiotics, forcing clinicians to resort to second-line choices that are not always equally effective, safe, and contribute to the increase in antibiotic resistance. Pediatricians and general practitioners can play a crucial role in recognizing and addressing weak suspicions of beta-lactam allergy, actively participating in removing the "label" of being allergic. The article, based on Who AWaRe Manual recommendations, presents current evidence on the issue with practical guidance to promote accurate interpretation and management of an overestimated problem that does not encourage a culture of optimal and prudent antibiotic use.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
