To the editor: The comprehensive article by Bennett, Plamp, and Porter on "Drug-Related Syndromes in Clinical Nephrology" (1) did not mention that lithium can produce a defect in urinary acidification. In both animals and man a decreased ability to lower urinary pH in response to acid loading has been shown (2-5). This defect has been described as a partial distal renal tubular acidosis with lithium-induced impairment of distal tubular hydrogen-ion secretion (5). Although high doses of lithium have produced a systemic acidosis in dogs (3), this has not been demonstrated in man. It is conceivable that lithium treatment might make
