ObjectiveTo evaluate the serum levels and diagnostic value of cytokines and acute phase proteins in patients with infective endocarditis (IE).Patients And MethodsSerum samples from 63 patients diagnosed with IE and 71 control patients were analysed for the following markers: interleukin-6 (IL6), tumour necrosis factor-alpha (TNF-alpha), interleukin 1-beta (IL1beta), procalcitonin (PCT), lipopolysaccharide binding protein (LBP) and C-reactive protein (CRP).ResultsSerum levels of IL6, IL1beta and CRP were significantly elevated in patients with IE as compared to controls. PCT, TNF-alpha and LBP were not elevated.ConclusionSerum CRP and IL6 are elevated in IE. IL 6 may aid in establishing the diagnosis. There was no correlation between IL 6 levels and CRP, causative microorganism, echocardiographic features or outcome.
