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.

A chronic “postinfectious” fatigue syndrome associated with benign lymphoproliferation, B-cell proliferation, and active replication of human herpesvirus-6

Abstract:

A 17-year-old, previously healthy woman developed an acute “mononucleosis-like” illness with an associated “atypical” pneumonitis, followed by years of debilitating chronic fatigue, fevers, a 10-kg weight loss, night sweats, and neurocognitive symptoms. Thereafter, her sister developed a similar but less severe illness.

The patient developed marked, chronic lymphadenopathy and splenomegaly, with associated persistent relative lymphocytosis and atypical lymphocytosis and with thrombocytopenia. After 3 years of illness, a splenectomy was performed, which resulted in some symptomatic improvement, prompt weight gain, and resolution of all hematologic abnormalities. Serial immunologic studies revealed a strikingly elevated number of activated B lymphocytes and a T lymphopenia, which improved but did not return to normal postsplenectomy. No causal association was found with any of several infectious agents that could produce such a lymphoproliferative illness.

However, both the patient and her sister had evidence of active infection with the recently discovered human herpesvirus-6. Seven years after the onset of the illness, the patient and her sister remain chronically ill.
