  • Title: Metabolic bone disease of total parenteral nutrition.
    Author: Klein GL.
    Journal: Nutrition; 1998 Jan; 14(1):149-52. PubMed ID: 9437701.
    Abstract:
    Parenteral nutrition-associated metabolic bone disease in children is manifested primarily as osteopenia and, on occasion, fractures. The etiology is likely multifactorial, with calcium and phosphate deficiency playing a major role in the preterm infant and with the role of aluminum toxicity yet to be clearly defined in this population. Lack of normal values of bone histomorphometry in the premature infant as well as lack of normal data for biochemical markers of bone turnover in these patients contribute to the uncertainty. Other factors that may play a role in the pathogenesis include lack of periodic enteral feeding; underlying intestinal disease, including malabsorption and inflammation; the presence of neoplasms; and drug-induced alterations in calcium and bone metabolism. The true incidence and prevalence of parenteral nutrition-associated bone abnormalities in pediatric patients remain unknown.
