The serum concentrations of interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), and interferon-gamma (IFN-gamma) were measured by enzyme immunoassays in 44 patients with Chlamydia (n = 13) or Mycoplasma (n = 14) pneumonia or influenza A infection (n = 17) and in 20 control subjects. The levels of IFN-gamma were raised in 29/44 patients. The concentrations of IL-6 were raised in 32/44 patients. Raised levels of TNF-alpha were seen in 26/44 but there was no significant difference between the levels of the different groups of patients. All three cytokines indicated clinical recovery when acute and convalescent samples from 10 patients with Chlamydia pneumonia were analyzed. IFN-gamma, IL6 and TNF-alpha are present in the circulation in the majority of patients with Chlamydia and Mycoplasma pneumonia and in influenza A infection. We suggest that repeated measurement of cytokines, such as IL-6, IFN-gamma and TNF-alpha, may be useful in the management of lower respiratory tract infections but further studies are needed to define the value of cytokine measurements in acute pneumonia.

A prospective study was performed to assess the relationship among interleukin-6, tumor necrosis factor-alpha, C-reactive protein serum concentrations, and the severity of mycoplasma pneumonia in 49 children. Mycoplasma pneumonia was diagnosed by chest film and anti-Mycoplasma pneumoniae IgM antibody test. Serum concentrations of interleukin-6 and tumor necrosis factor-alpha were measured by using enzyme-linked immunosorbent assays. Interleukin-6 serum levels in mycoplasma pneumonia patients with fever for more than 3 days (41.98 +/- 67.46 [SD] pg/mL) were significantly higher than those in patients with fever < or = 3 days (10.01 +/- 11.74 pg/mL, p < 0.05). Interleukin-6 serum levels in those patients whose chest films revealed patchy consolidations or pleural effusion (58.11 +/- 92.19 pg/mL) were significantly higher than those in patients whose chest films revealed peribronchial interstitial infiltration (15.94 +/- 20.81 pg/mL, p < 0.05). The mean levels of serum tumor necrosis factor-alpha were not statistically significant in the different duration of fever and chest film findings. These results suggest that interleukin-6 serum concentration, rather than tumor necrosis factor-alpha, may be a potential indicator of the severity and outcome of mycoplasma pneumonia.
