Parenteral nutrition has been reported to restore impaired immune function in nutritionally depleted patients. Lymphocyte and granulocyte function were studied before and after 2 weeks of total parenteral nutrition (TPN) in 9 depleted patients, 5 with gastrointestinal cancer and 4 with benign gastrointestinal disorders. The ability of purified blood lymphocytes to incorporate (14)C-labelled thymidine spontaneously and following mitogenic and antigenic stimulation was studied. Before TPN spontaneous lymphocyte activity was significantly increased and mitogen and antigen responsiveness significantly decreased in comparison to healthy controls. These abnormalities were more pronounced in patients with malignant disorders while the remaining patients showed a moderate impairment. No improvement in lymphocyte capacity was observed following 2 weeks of TPN. Granulocyte function measured as chemotaxis, phagocytosis, NBT-reduction and bactericidal capacity did not differ significantly between patients and controls and no changes were seen following nutritional treatment. These findings support the concept that the underlying disease and/or other factors rather than the secondary nutritional depletion are the main reasons for immune impairment. Furthermore, no immunomodulating effects of lipid emulsions on lymphocyte and granulocyte function, under these experimental conditions, were apparent.
