[Capacity of opsonic recognition of polymorphonuclear neutrophils in malnourished children].

The opsonic recognition capacity of polymorphonuclear neutrophils (PMNs) was evaluated in 19 noninfected children (13 eutrophic and 6 malnourished) and 22 infected children (10 eutrophic and 12 malnourished) by determining the rosette-formation capacity of the PMNs with sheep erythrocytes. After evaluating the percentage of rosette-forming neutrophils (RFN), we did not observe significant differences between the PMNs from eutrophic children and those from noninfected malnourished children (70.2 +/- 5% vs 67 +/- 3% respectively, P greater than 0.
