Viral infection is a common trigger for acute exacerbations of chronic
obstructive pulmonary disease (AECOPD). The aim of this study is to investigate
the expression of cytokines in AECOPD. Patients with AECOPD requiring
hospitalization were recruited. Meanwhile healthy volunteers of similar age that
accepted routine check-ups and showed no clinical symptoms of inflammatory
diseases were also recruited. Induced sputum and serum were collected. Induced
sputum of participants was processed and tested for thirteen viruses and
bacteria. Forty cytokines were assayed in serum using the Quantibody Human
Inflammation Array 3 (Ray Biotech, Inc.). The most common virus detected in virus
positive AECOPD (VP) was influenza A (16%). No virus was found in controls.
Circulating levels of IL-6, TNF-?, and MCP-1 were elevated in VP and coinfection
subjects (p < 0.05), while the levels of 37 other cytokines showed no difference,
compared with virus negative groups and controls (p > 0.05). Additionally, VP
patients were less likely to have received influenza vaccination. VP patients had
a systemic inflammation response involving IL-6, TNF-?, and MCP-1 which may be
due to virus-induced activation of macrophages. There are important opportunities
for further investigating AECOPD mechanisms and for the development of better
strategies in the management and prevention of virus-related AECOPD.
