Postcancer fatigue (PCF) is a frequently occurring, severe and invalidating problem, impairing quality of life. Patients with chronic fatigue syndrome (CFS) also suffer from severe fatigue symptoms. Although it is possible to effectively treat CFS, the nature of the underlying physiology remains unclear. The presence of an underlying immunological problem has been suggested as an explanation for PCF and CFS. The aim of this study is to compare the humoral and cellular immune responses upon influenza vaccination in PCF patients, CFS patients, non-fatigued cancer survivors, and healthy controls.
PCF (n=20) and CFS patients (n=20) will be vaccinated against influenza. Age and gender matched non-fatigued cancer survivors (n=20) and healthy controls (n=20) will be included for comparison. Antibody responses will be measured at baseline and at day 21 by a hemagglutination inhibition test. T cell responses will be measured at baseline and at day 7 by lymphocyte proliferation, activation, and cytokine secretion.

- Humoral and cellular immune responses after influenza vaccination in patients with postcancer fatigue and in patients with chronic fatigue syndrome. [ Time Frame: before vaccination, 1 and 3 weeks after vaccination (change in immune response from pre- to post-vaccination) ]Humoral and cellular immune responses after influenza vaccination in patients with postcancer fatigue and in patients with chronic fatigue syndrome. The humoral immune responses will be measured by the hemagglutination-inhibition antibody test. The cellular immune responses will be measured by T lymphocyte proliferation and cytokine secretion of peripheral blood mononuclear cells. A full blood cell count will be performed and hemoglobin, glucose, and cholesterol levels, iron status, electrolyte balance, erythrocyte sedimentation rate, and thyroid, kidney, and liver function will be checked.
