title: Low grade pyrexia: is it chronic fatigue syndrome?
abstract: Eighty seven consecutive patients presenting with prolonged low grade pyrexia (99 degrees-101 +/- F) during 1984-93 were followed up for a mean duration of 2.9 years. Mean age was 37.55 years (SD + 10.16) and 66 (75.8%) were females. Onset of pyrexia was acute in 57 patients and was associated with chilly sensation (42), Fatigue (69), Arthralgias (61), myalgias (55) and several other non specific symptoms. Clinical examination showed paucity of physical signs with 7 patients showing tender lymphadenopathy, 7 showing splenomegaly, 5 hepatomegaly, and 1 phylctenular conjunctivitis. Psychiatric examination was within normal limits. Extensive investigations for any viral or other infection, autoimmune disorder or malignancy were unrewarding. Patients were followed up for an average of 2.9 (2 to 5 years). Thirteen patients had become asymptomatic within one year of onset of symptoms, 38 by two years and 45 by the end of three years. This syndrome may be a variant of chronic fatigue syndrome.
