Abstract
|
|
|
A 22-year-old male patient was diagnosed with autosomal dominant polycystic kidney disease (ADPKD). He received conservative treatment with an angiotensin-converting enzyme inhibitor. Two years later, oral therapy, consisting of 60 mg tolvaptan per day, was initiated. Compared with height-adjusted total kidney volume, the rate of kidney growth reduced significantly from 7.33% to 0.66% annually, since commencement of the tolvaptan therapy. The liver enzyme profile and serum sodium level and osmolality were constantly within normal ranges. In Korea, this is the first reported case of a patient with ADPKD who received tolvaptan treatment for more than 1 year. This case demonstrates that long-term tolvaptan treatment appears to be safe, well tolerated, and effective for ADPKD.
