Clinical Trial Summary
Normal growth can be divided into four important phases: prenatal, infantile, childhood and
pubertal. Nutrition is important at all phases of growth, but particularly so during the
infantile phase because the rate of growth is higher than at any other time of life and is
less dependent on growth hormone than during other phases. During the childhood phase, growth
becomes more dependent on the GH/insulin-like growth factor-1 axis; growth rate decelerates
continuously until the pubertal phase. The pubertal phase results from the coordination of GH
and sex steroid production. Together they have an anabolic effect on muscle mass, bone
mineralization and body proportions. It is another phase of rapid growth so that nutrition
can again modify the genetic growth potential.
Description:
Achieving an optimal nutritional status is essential for managing paediatric chronic kidney
disease, and dietary guidance is frequently provided in clinical practice to achieve a
metabolic balance, which is vital for normal growth. Guidelines addressing optimal macro- and
micronutrient intake for children with CKD are available, with intake of sodium, potassium,
phosphorus, protein, and total calories being common targets of nutritional monitoring.
Normal nutrition can be defined as maintenance of normal growth and body composition.
Although it is agreed that nutritional assessment is important in chronic renal failure,
there is no single or easy definition or measure of inadequate nutritional status:
measurement of nutritional parameters are complicated in CRF because of salt and water
imbalances and the potential inappropriateness of using age matched controls in a population
that is short and may be delayed in puberty; it has been suggested that it is more
appropriate, therefore, to express measures relative to height age and/or pubertal stage.
Malnutrition is common in hem dialysis patients and is a powerful predictor of morbidity and
mortality. Although much progress has been made in recent years in identifying the causes and
pathogenesis of malnutrition in hemodialysis patients, as well as recognizing the link
between malnutrition and morbidity and mortality, no consensus has been reached concerning
its management. Along with such conventional interventions as nutritional counseling, oral
nutritional supplements, and dialectic parental nutrition, novel preventive and therapeutic
strategies have been tested, such as appetite stimulants, growth hormone, androgenic anabolic
steroids, and anti-inflammatory drugs, with contradictory and non conclusive results.
Malnutrition still remains a great challenge for nephrologists in the third millennium.
Growth failure is almost inextricably linked with chronic kidney disease and end-stage renal
disease.Growth failure in CKD has been associated with both morbidly and mortality .Growth
failure in the setting of kidney disease is multi factorial and is related to poor
nutritional status as well as co morbidities ,such as anemia, bone and mineral disorders, and
alterations in hormonal responses, as well as to aspects of treatment such as steroid
exposure. Initial reports of renal dwarfism date back to the turn of the twentieth century.
Despite advances in conservative treatment and renal replacement therapies, 30-60% of
patients with ESRD are short at adulthood.
Hypoalbuminemia is the most powerful predictor of mortality in end-stage renal disease. Since
protein-calorie malnutrition can decrease albumin synthesis it is assumed that hypoalbu
minemia results principally from malnutrition in these patients, but albumin synthesis may
also be decreased as part of the acute-phase response, and hypoalbuminemia can also result
from redistribution of albumin pools or from albumin losses.Serum albumin has been identified
as a surrogate marker for nutritional status and morbidity / mortality in patients with
end-stage renal failure. Although serum albumin may be a reflection of nutrition, low levels
may be due to haemodilution, nephrotic syndrome or chronic infection / inflammation.
The most commonly used assessment of nutrition is height and weight, along with head
circumference in younger children, plotted on percentile charts. Another way of expressing
the relative weight and height is the body mass index, which is important because extremes
are associated with increased morbidity and mortality. Skin fold thickness is a measure of
subcutaneous fat and mid-arm circumference is a reflection of muscle mass and may therefore
be more useful in determining body composition than the calculation of BMI alone.
