| Abstract: | 58 malnourished children (mean age 18 months) with a clinical diagnosis of marasmus or kwashiorkor were studied with respect to plasma fibronectin levels, plasma total solids, spun hematocrits, heights, weights, mid-arm circumferences, and head circumferences. Bimodal distributions were demonstrated for plasma fibronectin versus weight deficits, total solids, hematocrits, and mid-arm circumference in children 12 months of age and older (p less than 0.003 for all). The mean plasma fibronectin level for controls was 253 micrograms/ml. The mean level for the malnourished group was 96 micrograms/ml (p less than 0.0001). Malnourished children with initial plasma fibronectin levels above 100 micrograms/ml had a higher survival rate than those with levels less than 100 (92 versus 69%). With successful therapy, plasma fibronectin levels rose quickly in most children often before detectable changes were noted in clinical and other laboratory parameters. An overshoot of the mean normal levels was observed with successful treatment wherein the mean levels rose to 315 micrograms/ml (p less than 0.05). Plasma fibronectin determinations on malnourished children can serve as an important prognostic marker as well as a reliable indicator of successful therapy and recovery. |
