Renal lesions associated with hypokalemia. The predominant pathologic finding accompanying potassium depletion in humans is vacuolization of the epithelium of the proximal convoluted tubules. The vacoules are large and coarse, and staining for lipids is usually negative. The tubular vacuolation is reversible with sustained correction of the hypokalemia; however, in patients with long-standing hypokalemia, lymphocytic infiltration, interstitial scarring, and tubule atrophy have been described. Increased renal ammonia production may promote complement activation via the alternate pathway and can contribute to the interstitial nephritis [17,18].
