Acidosis and growth in nonuremic renal disease.
Our data demonstrate that correction of acidosis is sustained in children with type 1 RTA when alkali therapy is given in doses of 5 to 14 mEq/kg/day. The large doses are required as a result of renal bicarbonate-wasting. Children with type 1 RTA and acidosis who have significant growth impairment experience catch-up growth and attain normal stature for their age when correction of acidosis is sustained. Whether chronic acidosis impairs growth in any clinical condition except type 1 RTA is not settled. Whether sustained correction of acidosis with alkali therapy will allow attainment of normal stature in children with nonuremic diffuse renal disease is not yet determined. With the increasing availability of microchemistry and microgasometry and the new standards for growth based on mean-parent height [40], it can be anticipated that answers to these clinically important questions will be forthcoming.
