cent advances in our understanding of the immunological mechanisms that cau
se sepsis, Fever, a nonspecific acute-phase response, has been associated w

is article reviews the biological effects of fever and the influence of ant
ipyretic therapy on the outcome in sepsis in experimental models and in hum
ans and offers clinical recommendations for antipyretic therapy in early an
