Abstract
Abstract Background While a connection has been established between serum interleukin-6 (IL-6) levels and the IL-6 gene (− 174G/C) polymorphism in allergic diseases such as asthma, its specific association with severe asthma remains unexplored. This study examined the relationship between the IL-6 (− 174G/C) gene polymorphism and mild and severe asthma, focusing on its influence on type 2 inflammation. Methods Our study comprised 98 patients with mild asthma and 116 with severe asthma. Additionally, we recruited 121 healthy participants to serve as controls for comparative analyses. The IL-6 gene (− 174G/C) polymorphism was assessed utilizing the polymerase chain reaction-restriction fragment length polymorphism (PCR–RFLP) method. Results In our study, the risk of mild asthma exhibited a significant fourfold increase in individuals with the GG genotype pattern compared to healthy controls, yielding an odds ratio (OR) of 4.4 (p
