Abstract

Fever is a phylogenetically ancient host reaction to invading microorganisms and other noxious stimuli. Poikylothermic organisms can reach febrile temperatures by seeking a hot environment in response to a higher set point in their thermoregulatory center. Endothermic organisms produce febrile temperatures through endogenous heat production at the expenditure of a higher metabolic rate. Nevertheless, fever has been conserved during evolution through millennia, obviously because of its advantage for host defense. Despite of these arguments most doctors, nurses and patients treat fever with antipyretics. The role of fever for the recovery from low risk infections is marginal at best. A large study of ibuprofen in patients with severe sepsis could not establish a positive or negative role on the course or final outcome of the infection in an intensive care setting. These clinical observations seemingly contradict findings in severe experimental bacterial infections in rodents but it has to be taken into consideration that these animals, in contrast to patients, received no antibiotic treatment. In patients with influenza-like illnesses non-steroidal antirhumatics (NSAR) improve fever and wellbeing with little or no evidence for un...Continue Reading
