Evaluation of Serum IL-33, IL-5 and Trace Elements Levels among Asthmatic Patients

Abstract

The precise relationship between interleukins-33 and IL-5, as well as some trace elements and asthma, is unknown. The target of research was to compare and link the above-mentioned serological parameters in asthmatic patients and healthy controls. In 69 asthmatic patients and 35 healthy controls, serum levels of IL-33, IL-5, zinc, copper, iron, total IgE, Forced expiratory volume (FEV) and Forced expiratory volume (FEV) were compared. Spirometry was used to assess the (FEV) and (FVC) in asthmatic patients, as well as their age and body mass index (BMI). When asthmatic patients were matched to controls, mean levels of IL-33, IL-5, and total IgE appeared highly significant difference (p < 0.001). There was a substantial decline in zinc levels in the asthmatic group, but no significant drop in Copper levels. There was also a statistically significant difference in high Iron mean levels among asthmatic patients. In addition, the findings revealed a significant positive correlation between Iron and IgE levels in patients and the levels of (IL-33 and IL-5), plus a significant negative correlation with Zinc levels. Only Copper had no relationship with the interleukins studied. IL-33, also known as IL-5, is a novel inflammatory marker implicated in asthma progression by interacting with IgE, Zinc, Iron, but not Copper levels. As a result, it could be a one-of-a-kind therapeutic target in these patients.
