IL-6 (-572G/Crs1800796) and IL-6R (1:G.154448302 T > C rs7529229) gene polymorphisms may have an impact on cytokine production, immune response and these gene polymorphisms may be used as inflammatory markers in the diagnosis of appendicitis.
We looked for associations between the severity of appendicitis (uncomplicated vs. perforated or gangrenous), plasma and peritoneal cytokine concentrations, and single nucleotide polymorphisms in genes involved in recognizing bacterial molecules [CD14 (-159 C-->T); TLR4 (896 A-->G)] and in mounting an inflammatory response [IL-6 (-174 G-->C), TNF-alpha (-308 G-->A), IL-1beta (-31 C -->T)].
