Clinical and laboratory findings in the Paul-Bunnell negative glandular fever-fatigue syndrome.
Forty-one patients with recurrent fatigue were studied for evidence of symptom clustering, abnormal laboratory findings and infection with novel viruses. Symptom enquiry and investigations were repeated 4 months later. Four patients were found to have diseases compatible with their symptoms. In those remaining, an initial acute onset of symptoms was associated with an intermittent course, tender glands and a raised number of T suppressor lymphocytes. Raised numbers of T suppressor lymphocytes at follow-up correlated with resolution of symptoms. Antibodies to human herpesvirus 6 (HHV-6) were found in 75% of the patients as compared to 53% of a control group and more patients than controls were strongly seropositive. Some patients with chronic fatigue have a pattern of illness which suggests glandular fever, although acute infection with Epstein-Barr virus (EBV) is not demonstrated. Primary or reactivation infection with HHV-6 may have a role in this syndrome.
