title: Non-steroidal anti-inflammatory drug-associated nephrotoxicity in Bartter syndrome.
abstract: We have followed four patients with Bartter syndrome for a mean of 25.4 years (range 21.5-28.8 years) after diagnosis. All patients received non-steroidal anti-inflammatory drugs (NSAID). In all patients, various degrees of renal dysfunction were noted to be temporally associated with NSAID therapy. In two patients, renal dysfunction resolved after discontinuing NSAID therapy, while maintaining other chronic medications such as potassium-sparing diuretics. Renal dysfunction persisted after NSAID withdrawal in two patients. We report these cases as a warning that NSAID should be considered an important cause of either reversible or irreversible renal dysfunction in Bartter syndrome.
