[Bartter's syndrome: the long term effects of indomethacin on growth (author's transl)].

Six children with Bartter's syndrome aged 6 years 4 months to 13 years 11 months were treated with indomethacin (1.7 to 4.3 mg/kg/day) during 7 to 27 months. A catch up growth was first observed, then growth curve was parallel to the normal. A catch up weight was also observed. The osseous maturation was the faster it was more delayed. These changes were observed despite a partial correction of potassium and plasma renine activity.
