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.

Children with cancer represent a high-risk group for protein-energy malnutrition due to side effects associated with treatment. Assessment of nutritional status at the time of diagnosis and during treatment is, therefore, essential for planning nutritional intervention. We studied the nutritional status of 25 children with leukemia [9 newly diagnosed/relapsed (D/R) leukemic patients and 16 children with leukemia in remission (REM)]. Plasma proteins (prealbumin, PA; albumin, Alb; transferrin, Tr; retinol-binding protein, RBP) and acute phase-reactant proteins (alpha 1-acid glycoprotein, AGP; C-reactive protein, CRP; ceruloplasmin, CER) were measured by radial immunodiffusion. Results show that there were no significant deficits in anthropometric measurements among leukemic children. In contrast, the mean levels of all plasma proteins, especially PA (P < 0.005), were significantly lower in the D/R group than in the REM group. All D/R children, compared to 59% of those in remission, had PA levels < 20 mg/dl. Only the D/R group had abnormal levels of RBP, Tr, and Alb. Children who were treated with prednisone had significantly higher mean levels of PA, RBP, and AGP than those who were not receiving prednisone. The mean levels of acute phase-reactant proteins in these leukemic children were comparable to those of healthy children. We conclude that mild/moderate malnutrition is common in leukemic patients at D/R and that PA seems to be the most sensitive indicator of visceral protein status.

Nutritional status of 80 preoperative patients from programmed surgeries of hernias and lithiasis was studied by anthropometric and biochemical parameters. Nutritional deficiencies related to pathology were not expected in these patients. Results were as follows: 77% of the population showed overweight, being 15% obese. Prevalent protein intake, evaluated by the urea nitrogen/creatinine ratio, was adequate in 87.5% of the patients; however, patients presented 72% of albumin, 52% of prealbumin and 50% of RBP below reference values. Transferrin, ceruloplasmin, alpha 2-macroglobulin and haptoglobin were not decreased. Assessment of vitamin A, carotenes and vitamin C showed plasmatic levels below reference values in 16% of the patients for vitamin A, 5% for carotenes and 27% for vitamin C. Respect to calcium status, data of calcium/creatinine ratio show deficiency in 45% of the population. Respect to iron, the nutritional status was in general adequate, patients at risk being 5% by Htc, 11% by Hb, 5% by TS% and 12.5% by FEP, women showed over twice abnormal values than men. Although some isolated relations were observed, in this population sex, age and pathology were variable that did not affect in a relevant way the nutritional status. In spite of the individual analysis of each nutrient did not show important deficiencies, the analysis by patient showed that only a few of them (7%) presented an optimal biochemical profile with all the studied parameters within the reference values.
