[The effect of preoperative parenteral nutrition on the capacity of the immune response in malnourished patients (preoperative parenteral nutrition and immunity)].

The objective of this study is to evaluate the response of the subpopulations of lymphocytes and IGs to the administration of total parenteral nutrition for 7 days in 26 patients suffering from malnutrition, 12 of whom had digestive neoplasia and 14 non-neoplastic gastrointestinal disorders. Following the total parenteral nutrition, a significant increase in the percentage of T-helper lymphocytes was noted, and an improvement in the OKT4/OKT8 quotient, as well as in the IgA and the C4 fraction of the complement. The existence of neoplastic conditions did not have a significant effect on the variations in the parameters studied. The presence of lipids in the parenteral nutrition diet did not affect the subpopulations of lymphocytes.
