The kidney in hypergammaglobulinemic purpura.
A 25-year-old woman with long-standing hypergammaglobulinemic purpura developed distal renal tubular acidosis and a urine-concentrating defect. The acidification defect was characterized as suggestive of impaired distal proton secretion by infusion of neutral phosphate. The concentrating defect was a form of acquired nephrogenic diabetes insipidus. On renal biopsy, IgM mesangial nephropathy was found along with multiple large hyaline tubular casts. The renal findings in hypergammaglobulinemic purpura are reviewed.
