RENAL TUBULAR ACIDOSIS

Renal tubular acidosis is a relatively rare but well documented disorder of renal acidification in which both the rate and concentration of acid excretion are subnormal during metabolic acidosis. The report of Morris and Fudenberg 1 has called attention to the association of hyperglobulinemic states which defects in urine acidification. In this regard, we have recently studied a patient with inability to acidify the urine, adult Fanconi syndrome, γ-globulinuria, and a primary myopathy. To the best of our knowledge, this combination has not been previously described.
