Abstract:
Histamine intolerance is a common disorder associated with an impaired histamine metabolism. It should be considered in individuals with sporadic or repeated anaphylaxis-like symptoms after seafood consumption. We encountered a 26-year-old male patient who experienced recurrent episodes of anaphylaxis-like symptoms after ingesting seafood. A detailed history-taking and a histamine 50-skin-prick test confirmed the diagnosis of histamine intolerance. In addition, a low-histamine diet and prophylactic antihistamine medication did not result in symptom recurrence. Proper management of histamine intolerance can improve the individual's quality of life.

Asthma-I: Introduction
Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
