title: Interleukin -1beta (IL-1 beta), interleukin 6 (IL-6) and tumor necrosis factor (TNF) in plasma and pleural fluid of pneumonia, lung cancer and tuberculous pleuritis.
abstract: Interleukins IL-1beta, IL-6 and TNF are increased in plasma of patients with severe infections and septic shock. Our objective was the evaluation of IL-1beta, IL-6 and TNF in plasma and exudates of pleural fluid and their contribution to the diagnosis. We studied 44 patients, 27 men and 17 women with mean age 66.81 +/- 11.75 years; 16 with pneumonia and parapneumonic effusion, 14 with primary lung cancer and pleural effusion and 14 with tuberculous pleuritis. We measured IL-1beta, IL-6 and TNF in serum and pleural fluid with ELISA. In patients with pneumonia and parapneumonic effusion the mean value of IL-1beta IL-6 and TNF in plasma was 9.05, 19.24 and 21.34 pg/ml and in pleural fluid 10.34, 32.19 and 25.30 pg/ml. In patients with lung cancer the mean values of IL-1beta, IL-6 and TNF were 5.33, 11.74 and 11.51 pg/ml and 6.70, 13.13, 20.89 pg/ml, respectively. In those with tuberculous pleuritis the respective mean values were 10.33, 49.94, 21.27 pg/ml and 14, 56.59, 23.58 pg/ml. In conclusion, IL-1beta and IL-6 were found increased in plasma and tuberculous pleural fluid, indicating an inflammatory status.
