[Cellular immunity in protein-caloric malnutrition].

In order to have a clearer idea on the relationship between infectious diseases and malnutrition, cellular immunity is studied in 3 to 18 months old malnourished and healthy infants. Nutritional status is evaluated by the food intake the anthropologic measurements and some biological parameters like transferrin. Cellular immunity is investigated by skin tests to tuberculin, monilia, P.H.A. and DNCB. Absolute number of peripheral lymphocytes and percentage of T cells are studied too. The results show that there is a cellular immunity deficiency: frequent non-response to antigens, weak sensitization to DNCB. Some patients have a low percentage of spontaneous rosettes. The transferrin titering is useful to appreciate the nutritional status and the iron therapy opportunity, the prognostic and the immunitary possibilities.
