Serum albumin, retinol-binding protein, thyroxin-binding prealbumin and acute phase reactants as indicators of undernutrition in children with undue susceptibility to acute infections.
This study was conducted in order to test the usefulness of measuring the concentrations of selected serum proteins and acute phase reactants in assessing the nutritional status of children with undue susceptibility to acute infections. The concentrations of serum proteins were determined by an immunodiffusion technique in 28 children with undue susceptibility to infections and were compared with those in healthy children. The patients were grouped according to the clinical pattern, i.e. into children with mainly upper respiratory tract infections, with frequent middle ear infections and with lower respiratory tract infections. The total group and all three subgroups of patients had not only significantly lower (p less than 0.001 or p less than 0.01) mean serum levels of albumin and retinol-binding protein, but also of the acute phase reactants alpha 2-macroglobulin and ceruloplasmin (p less than 0.01) than the controls. No differences were observed between the patients and the controls in respect of the acute phase reactant orosomucoid. This study indicates that the concentrations of albumin and RBP along with selected acute phase reactants are rapidly influenced by altered nutritional status in children with undue susceptibility to acute infections.
