It is said that maintenance hemodialysis patients are already suffering from secondary hyperparathyroidism (2HPT) from eary stage of chronic renal failure. The treatment of 2HPT in this stage is very important for preventing renal osteodystrophy (ROD). But many long-term dialysis patients are still afflicted with ROD although vitamin D have been used for treatment. In this study, an oral administration of 1-25 (OH)<SUB>2</SUB> D<SUB>3</SUB> (4μg) with pulse therapy twice a week at the day before hemodialysis was started for 12 weeks. The concentration of 1-25 (OH)<SUB>2</SUB>D<SUB>3</SUB>, total calcium (Ca), ionized calcium (Ca)<SUP>++</SUP>, alkaline phosphatase (ALP) and parathyroid hormone (PHT) in serum were measured not only before and after every 2 hours of administration a day, but also for 12 weeks after that. The peak of serum 1-25 (OH)<SUB>2</SUB>D<SUB>3</SUB> could be sufficiently elevated after 8 hours, and the slight peak of Ca<SUP>++</SUP> could be seen after 8 hours as well. But the level of total calcium could not increased. Although the level of only HS-PTH has not increased after 24 hours, a significant reduction in serum level of C-PTH, intact-PTH and HS-PTH could be recognized after 12 weeks finally. This pulse therapy was effective in reducing the serum level of PTH in this eary stage from beginning hemodialysis. But, it needs further studies for the standard treatment.
