In a study of the pathogenesis of the oedema of kwashiorkor the ultrastructure of the kidneys from 6 children was examined shortly after they died from oedematous malnutrition. There was a generalised effacement of the glomerular epithelial cells onto the basement membrane. The filtration slits that remained were narrowed. The picture was similar to that seen in minimal-change nephrotic syndrome--but none of the children had albuminuria. The degree of effacement was statistically related to treatment with gentamicin. The findings suggest that there is a defect in the anionic charge of the glomerular basement membrane in oedematous malnutrition, that the membrane charge is more easily neutralised by cations such as gentamicin, and that, because proteinuria is not a feature of oedematous malnutrition, the proteinuria in other conditions associated with glomerular epithelial cell effacement (eg, minimal-change nephrotic syndrome) is due to something more complex than simple loss of charge.

Thirteen patients (7 males, 6 females, aged 17-68 years) affected by primary, steroid-resistant, nephrotic syndrome and normal renal function were treated with a vegan, low-protein (0.7 g/kg per day) diet supplemented with essential amino acids and Ketoanalogues (VSD) for 3.9 +/- 2.9 months. These patients were studied at the beginning (following an unrestricted protein diet (UPD) supplying about 1 g/kg per day of mixed proteins) and at the end of VSD period. Urinary protein excretion decreased from 8.7 +/- 2.6 to 5.6 +/- 2.4 g/day (P less than 0.01), serum total cholesterol from 334.6 +/- 97.1 to 275.6 +/- 49.4 mg/dl (P less than 0.05). Serum albumin, HDL-cholesterol, triglycerides, and anthropometric measurements (triceps skinfold thickness and middle arm muscle circumference) did not change. Urinary urea nitrogen decreased from 7.5 +/- 1.8 to 3.8 +/- 1.2 g/day (P less than 0.005), according to dietary prescriptions. Creatinine clearance changed from 104.4 +/- 28.7 to 89.3 +/- 16.7 ml/min (n.s.) and no correlation was found with the changes in urinary protein excretion. This data suggest that VSD reduces proteinuria and exerts favourable effects on hypercholesterolaemia. Protein malnutrition was absent in these patients, probably because of the essential amino acids and ketoanalogues supplementation.

The purpose of the study was to establish the influence of protein restricted diet supplemented with EAA/KAA on nutritional status of children with CRF. Seven childredn (four girls and three boys), aged from 7 years and eight months to 14 years and two months, with glomerular filtration rate of 42.6-9.2 ml/min/1.73 m2 and proteinuria of 0.025-1.125 g/24 h, who were on conservative treatment and who lived at home, were observed for six months. In prescribing energy value and protein intake WHO recommendations were used for healthly children (age for height). Through food 80-90% of energy and 80-85% of protein needs were provided. The remaining energy and proteins were provided by glucodextrin and EAA/KAA supplements respectevely. Average daily phosphorous intake amounted to about 550-800 mg. The obtained results showed that stunting and kwashiorkor like aminoacid disbalance were the prominent nutritional problems. This dietary regimen had a beneficial effect on all studied parameters. especially on height standard deviation score which increased from 1.71 +/- 2.6 to 1.5 +/- 4.3 (t = 2.809, p < 0.05); total essential/nonessential aminoacid score increased from 0.38 +/- 0.2 to 0.56 +/- 0.2 (t = 2.763, p < 0.05). The ratio between plasma concentration of four nonessential (glycine+serinet glutamine+taurine) to four essential (leucine+isoleucine+valine+methionine) amino acids decreased from 3.82 +/- 1.2 to 2.7 +/- 0.4 (t = 2.528, p < 0.05). Lymphocyte count increased from 1.809 x 10(9) +/- 0.268 x 10(9)/l to 2.314 x 10(9) +/- 0.922 x 10(9)/l (t = 2.431, p < 0.05). No significant changes were found in the values of relative body weight, arm circumpherence, triceps skinfold thickness, total plasma protein, albumin, transferine, complement C3 and plasma valin/glycin and phenylalanine/thyrosine ratio. It should be noted that the significant changes were not found in the results of these latter anthropometric biochemical parameters in relation to their primary almost insignificant values.
