Ageing is a major risk factor for neurodegenerative diseases like Alzheimer's disease (AD). Microglia, as the principal innate immune cells within the brain, exert homeostatic and active immunological defense functions throughout human lifespan. The age-related dysfunction of microglia is currently recognized as a pivotal trigger for brain diseases associated with aging.

Natural killer (NK) cells are innate immune cells that play a crucial role as a first line of defense against viral infections and tumor development. Iron is an essential nutrient for immune cells, but it can also pose biochemical risks such as the production of reactive oxygen species. The importance of iron for the NK cell function has gained increasing recognition.

Introduction: The idea that chronic inflammatory processes may play a role in the etiopathogenesis of both treatment - refractory chronic spontaneous urticaria and cardiovascular diseases is an important research topic.
Aim: Within the scope of this research, we aimed to elucidate a new perspective on the follow-up of chronic urticaria patients by evaluating the 10-year cardiovascular risk and metabolic syndrome in resistant chronic spontaneous urticaria patients who were unresponsive to maximum antihistamine treatment.
Material And Methods: A total of 170 individuals who applied to our institution's Health Science University, Tepecik Education and Research Hospital, allergy and immunology outpatient clinic have been analysed in this retrospective case-control study.
