A 44 year old female with renal tubular acidosis, osteomalacia, lipemia and aminoaciduria is reported. Mild hypocalcemia, marked hypophosphatemia and elevated serum alkaline phosphatase were associated with high serum immunoreactive parathyroid hormone level, which was promptly suppressed by intravenous calcium infusion, indicating secondary hyperparathyroidism. Among 56 cases of renal tubular acidosis so far reported in Japan, patients in the first decade predominated and the male to female ratio was 1 to 3. Osteomalacia was found in 19 and hypergammaglobulinemia in 11 but aminoaciduria was seen only in 2. Marked lipemia was the most unusual aspect in the present case.
