Abstract
Experimental studies show the unique aspects of cytokines profiles in various inflammatory diseases of the lung lead to different clinical manifestations. To elucidate the potential role of cytokines in the pathogenesis of bronchial asthma, plasma interleukins-1 beta, interleukin-6, interferon-gamma and tumour necrosis factor-alpha were measured in 32 asthmatics during an onset of acute asthma. Nine healthy volunteers were included as controls. Cytokine levels were measured by using commercially available ELISA kits. Our results showed that except for interleukin-6, increased concentrations of cytokines were not detected in the controls. Detectable concentrations of IL-6 and TNF-alpha were more common in patients than in controls. However, Interferon-gamma concentrations were below the threshold of detection in both patient and control groups. In conclusions, our results suggest that IL-6 and TNF-alpha are involved during the onset of an acute attack of asthma once the threshold limit has been passed. Hence, these two cytokines are important markers of the inflammatory components of acute asthma.
