[Inhibition of prostaglandin synthesis during the therapy of nephrogenic diabetes insipidus].

A report is presented of a male infant with nephrogenic diabetes insipidus type I. A low-solute-load diet and large fluid intake were not able to prevent hypertonic dehydration and to control the disease. It responded within 3 days to indomethacin (3 mg/kg body weight), a prostaglandin synthetase inhibitor. The boy is doing well on this regimen and no side-effects have been observed after 2 years of treatment. Hitherto only a few case reports have been published on this therapeutic regimen, but all confirm the high efficacy of prostaglandin synthesis inhibition as the treatment of choice in nephrogenic diabetes insipidus.
