RT Journal Article SR Electronic T1 The ying and yang of fever in rheumatic disease JF Clinical Medicine JO Clin Med FD Royal College of Physicians SP 288 OP 291 DO 10.7861/clinmedicine.15-3-288 VO 15 IS 3 A1 James Galloway A1 Andrew P Cope YR 2015 UL http://www.rcpjournals.org/content/15/3/288.abstract AB Fevers are relatively common in rheumatic disease, largely due to the fact that the inflammatory process is driven by inflammatory mediators that function as endogenous pyrogens. Since the immune system's sensors cannot accurately distinguish between endogenous and exogenous (pathogen-derived) pyrogens a major challenge for physicians and rheumatologists has been to decipher patterns of clinical signs and symptoms to inform clinical decision making. Here we describe some of the common pitfalls and clinical challenges, and highlight the importance of a systematic approach to investigating the rheumatic disease patient presenting with fever.
