Persistent nephrogenic diabetes insipidus, tubular proteinuria, aminoaciduria, and parathyroid hormone resistance following longterm lithium administration.

We report a patient who developed persistent nephrogenic diabetes insipidus associated with renal tubular acidosis, renal resistance to parathyroid hormone, aminoaciduria and proximal tubule pattern proteinuria in the presence of a reduced glomerular filtration rate (19-24 ml/min). A review of the previous reports of persistent nephrogenic diabetes insipidus revealed that in all patients the glomerular filtration rate had been less than 60 ml/min at presentation. Chronic renal failure may therefore predispose to the development of persistent nephrogenic diabetes insipidus in patients receiving lithium.
