Our objective was to investigate the initial levels of circulating proinflammatory cytokines, such as interleukin 1 beta (IL-1 beta), interleukin 6 (IL-6), and tumour necrosis factor alpha (TNF-alpha), of certain acute-phase proteins, such as C-reactive protein (CRP), fibrinogen (FBN) and albumin, and of the glycoprotein fibronectin at presentation and their daily variation during the clinical course of community-acquired pneumonia (CAP) in relation to clinical and laboratory indices of infection. Thirty otherwise healthy hospitalized patients aged 48 +/- 3 years (mean +/- SEM) and with bacteriologically confirmed CAP were studied prospectively. IL-1 beta and IL-6 were found to be 15-fold higher on admission (122 +/- 9 pg mL-1 and 60 +/- 4 pg mL-1 respectively), whereas TNF-alpha was three-fold higher (102 +/- 5 pg mL-1) than those of controls, all of them showing a decline towards normal. Initial CRP levels were increased 90-fold (416 +/- 1 mg L-1), whereas fibronectin levels were reduced (242 +/- 9 mg dL-1). The presence of parapneumonic effusion was associated with a higher TNF-alpha serum level (127 +/- 7 vs. 86 +/- 4 pg mL-1, P = 0.0002), a more rapid daily decline in TNF-alpha (-7.2 +/- 0.7 vs. -3.8 +/- 0.5 pg mL-1 day-1, P = 0.0005), a slower rate of decline in CRP (-42.8 +/- 3.0 vs. -54.6 +/- 3.0 mg L-1 day-1, P = 0.02) and a slower rate of increase in FBN (5.9 +/- 1.0 vs. 11.7 +/- 1.0 mg dL-1 day-1), P = 0.001]. Furthermore, daily progression of serum levels of cytokines and acute-phase proteins correlated strongly with pyrexia, erythrocyte sedimentation rate (ESR), neutrophil count, alveolar-arterial oxygen difference and radiographic resolution, clinically manifested by improvement in the patients' condition.
