Hospital-acquired pneumonia is a serious and potentially life-threatening complication, with reported pneumonia-attributable mortality rates as high as 50%. Rapid diagnosis and immediate institution of adequate empirical antimicrobial treatment are of paramount importance in patient management. Nevertheless, some patients deteriorate and develop respiratory insufficiency, septic shock and a multiorgan dysfunction syndrome. Early recognition of these patients might help in reducing morbidity and mortality. Elevated systemic levels of proinflammatory cytokines (IL-1beta, IL-6, IL-8 and IL-10) at the time of diagnosis of hospital-acquired pneumonia appear to be indicative of subsequent progression to septic shock. Should this now become a part of patient management?
