    Notes: Abstract  Diarrhoea-associated haemolytic uraemic syndrome (D+ HUS) is usually caused by verotoxin-producing Escherichia coli. Histology shows endothelial swelling with localised thrombus. Activation of coagulation and fibrinolysis also occurs. These facts, combined with the knowledge that recovery usually follows within weeks, led us to hypothesise that verotoxin causes localised endothelial cell activation but not injury. Markers of endothelial cell activation and injury were measured serially in 30 children with acute D+ HUS, healthy children, and children receiving chronic dialysis. Interpretation of markers was complicated by the renal dysfunction characteristic of D+ HUS. Nevertheless there was no evidence for endothelial cell injury, as soluble tissue factor levels were not increased and soluble thrombomodulin levels were lower than dialysed controls (P〈0.001). In the acute phase, soluble vascular cell adhesion molecule levels were raised above normal (P〈0.001), but were lower than dialysed controls (P〈0.001), and soluble E-selectin levels were not significantly increased compared with normal controls (P=0.2). Hence, there was no evidence for endothelial cell damage or endothelial cell activation by the time children reached hospital; but this study did not exclude the possibility that endothelial cell activation occurred prior to hospital admission.

    Notes: Abstract Eleven boys, mean age 15.3 years (range 13.2–17.5), with pubertal delay in association with steroid therapy for steroid-sensitive nephrotic syndrome and following renal transplantation were treated with oxandrolone 2.5 mg daily for a mean of 0.50 years (range 0.34–0.61). Mean growth velocity increased from 3.9 cm/year (range 1.1–6.3) to 6.1 cm/year (range 2.0–14.4) and was maintained at 6.1 cm/year (range 0.4–10.2) (P〈0.05). However, there was no significant difference in growth between the treated boys and age- and puberty-matched controls. Elevation of blood cyclosporin A and creatinine levels occurred in the transplant patients. Oxandrolone may initiate a pubertal growth spurt in patients taking steroid therapy for renal disease, but should be used with extreme caution because of potential side-effects.

    Notes: Abstract Sodium (Na) is an important growth factor, stimulating cell proliferation and protein synthesis and increasing cell mass. Sodium chloride (NaCl) deprivation inhibits growth, as reflected by reduced body and brain weight, length, muscle and brain protein and RNA content and brain lipid content compared with controls. This is not due to deficiency of other nutrients since control and experimental diets were identical except for NaCl content. Subsequent NaCl supplementation restores growth velocity to control values but does not induce “catch-up” growth. In humans, salt loss causes growth failure and subsequent salt repletion improves growth. Preterm infants 〈32 weeks' gestation at birth are renal salt losers in the first 2 weeks of post-natal life and are vulnerable to hyponatraemia. This can be prevented by increasing Na intake, which also produces accelerated weight gain that persists beyond the period of supplementation. Early nutrition in preterm infants can affect subsequent growth and also cognitive function: this is probably multifactorial, but NaCl intake differed substantially between study groups and is likely to be an important factor. The mechanism whereby Na promotes cell growth is not understood, but stimulation of the membrane Na+,H+-antiporter with alkalinization of the cell interior is a likely possibility.

    Notes: Abstract. We studied 34 apparently healthy children and 2 propositi from kindreds with familial juvenile hyperuricaemic nephropathy (FJHN) – a disorder characterised by early onset, hyperuricaemia, gout, familial renal disease and a similarly low urate clearance relative to glomerular filtration rate (GFR) [fractional excretion of uric acid (FEur) 5.1±1.6%] in young men and women. In addition to the propositi, 17 asymptomatic children were hyperuricaemic – mean plasma urate (368±30 μmol/l), twice that of controls (154±41 μmol/l). Eight of them had a normal GFR (〉80 ml/min per 1.73 m2), and 11 renal dysfunction, which was severe in 5. The FEur in the 14 hyperuricaemic children with a GFR 〉50 ml/min was 5.0±0.5% and in the 5 with a GFR ≤50 ml/min was still low (11.5±0.2%) compared with controls (18.4±5.1%). The 17 normouricaemic children (185±37 μmol/l) had a normal GFR (〉80 ml/min) and FEur (14.0±5.3%). The results highlight the dominant inheritance, absence of the usual child/adult difference in FEur in FJHN and presence of hyperuricaemia without renal disease in 42% of affected children, but not vice versa. Since early allopurinol treatment may retard progression to end-stage renal failure, screening of all relatives in FJHN kindreds is essential.

    Notes: Abstract Creatinine clearance (Ccr) and renal sodium (Na+) excretion were measured in 10 premature infants (gestational age 〈34 weeks) whose mothers had received dexamethasone before delivery (group D) and in 11 whose mothers were not so treated (control, group C). Babies were studied twice: on days 2–5 (study 1. all infants) and days 6–10 (study 2, six infants in each group). In study 1, absolute and fractional Na+ excretion were significantly lower (P〈0.01) and urinary K+∶Na+ ratio significantly higher (P〈0.025) in group D than in group C, while Ccr did not differ between groups. In study 2, Ccr in group D had increased compared both with values obtained in the same babies in study 1 (P〈0.05) and with group C babies in study 2 (P〈0.05), but significant differences between groups in urinary Na+ excretion and urinary K+∶Na+ ratio were no longer found. We conclude that exogenous glucocorticoids accelerate maturation of renal function in immature human infants, probably by inducing tubular Na+. K+-ATPase activity. Our findings support the view that endogenous glucocorticoid hormones may play an important part in the normal maturation process.

    Notes: Abstract Forty-five children with stable chronic renal failure, not on dialysis, were treated conservatively with a regimen of mild dietary phosphate restriction and high-dose phosphate binders for up to 5 years. Both aluminum hydroxide and calcium carbonate were used initially, but almost all patients were taking calcium carbonate towards the end of the period. Serum immunoreactive parathyroid hormone concentrations were significantly decreased and were within the normal range after 1 year and remained normal during treatment. There was no significant change in renal function over the same treatment period. We conclude that calcium carbonate should be used as the phosphate binder of choice in the long-term suppression of hyperphosphatemia and hyperparathyroidism in uremic children.

    Notes: Abstract Six children (aged 3 years 11 months to 15 years 9 months) with end-stage renal failure and anaemia (mean haemoglobin 7.1 g/dl, range 6.3–7.7 g/dl) on thrice-weekly haemodialysis were treated with recombinant human erythropoietin (rHuEPO), given as an intravenous bolus in an escalating dose regime after dialysis. All responded with an increase in reticulocyte count and haemoglobin concentration in a mean time of 11 weeks (range 9–13 weeks) and at a dose of 100 or 150 units/kg thrice weekly. The dose of rHuEPO was then adjusted to maintain the haemoglobin concentration within the lower half of the normal range for the child's age and sex. The mean haemoglobin after 12 weeks treatment was 10.9 g/dl (range 8.5–12.1 g/dl) and after 24 weeks, 10.5 g/dl (range 7.9–13.3 g/dl). Four chidlren had no further need for blood transfusion and are thus no longer at risk of blood-borne infection, iron overload and sensitisation to HLA histocompatibility antigens. Serum ferritin fell in the three patients with evidence of iron overload; the three with low or normal iron stores at the onset of treatment maintained erythropoiesis with oral iron supplementation. HLA antibodies decreased in all patients. The only serious complication encountered was thrombosis of vascular access in one child. No child became seriously hypertensive or developed cerebral symptoms. The benefits of rHuEPO therapy for children with end-stage renal failure are potentially considerable and with careful monitoring, the risks low.

    Notes: Abstract The results of treatment of glomerulonephritis (GN) in childhood with oral corticosteroids, immunosuppressive drugs, anticoagulants and the newer regimens of pulsed, high-dose intravenous methylprednisolone and plasma exchange are reviewed and compared with the natural history of the untreated condition. Poststreptococcal GN and the nephritis of Schönlein-Henoch purpura need no specific treatment unless extensive glomerular crescents are present. The progression of mesangiocapillary GN can probably be slowed or even reversed with long-term, alternate-day steroid therapy. As in adults, recovery of renal function in GN due to antibody to glomerular basement membrane can be achieved in some patients using plasma exchange, but only those in whom some renal function is still present when treatment is started. In rapidly progressive (extracapillary) GN with crescents, “traditional” therapy with oral steroids, immunosuppressive drugs and anticoagulants reduces renal mortality from 85%–90% to about 50%, while pulsed methylprednisolone and plasma exchange improve the outcome further, mortality falling to about 25%. It is recommended that children with crescentic GN and deteriorating function be treated initially with pulsed methylprednisolone, followed by plasma exchange in those who fail to respond or who deteriorate following temporary response to pulse therapy. Treatment must be given early in the course of the illness if good results are to be obtained.
