Urinary cyclic AMP and renal concentrating capacity in infants

Abstract: In 15 infants between 1 and 31 weeks the effect of antidiuretic hormone (ADH) on the renal concentrating capacity and urinary cyclic AMP (cAMP) was tested. A significant decrease of urine flow and a significant increase of osmolality, urea and cAMP was observed indicating that the distal nephron of the infant kidney is responsive to exogenous ADH and that its effect is mediated by cAMP. The results of a second series with 52 normally hydrated infants demonstrate that the nonlinear age-related increase of osmol… Show more

“…Parents are encouraged to offer a variety of flavours and textures and to include Fe-rich foods, as infant stores in Fe start to diminish from 6 months. It is recommended that added salt is avoided (5) , and that parents should abstain from giving sugar-or honey-containing foods (6) . In addition, the WHO guidelines advise parents on portion sizes and frequency of meals, on a feeding environment with no distractions, as well as on food safety when preparing and storing food (7) .…”

“…The rate of water renal excretion is influenced by the solute load to be excreted. As the renal concentrating capacity is limited in the neonatal period (Joppich, 1977), a high solute load could result in a rapid and profound alteration in water balance. Renal solute load is derived from exogenous and endogenous sources.…”
