The purpose of this study was to investigate gouty arthritis in Japanese patients with end-stage renal disease (ESRD).
Questionnaires plus patient interviews and reviews of medical records were used to investigate gouty arthritis in 493 Japanese patients with ESRD receiving maintenance dialysis.
The frequency of gouty arthritis was 4.1% for female patients and 15.4% for male patients greater than 2 years before the start of dialysis, and 0.6% for female patients and 7.7% for male patients less than 2 years before the start of dialysis. After the start of dialysis the frequency was 3.4% for the first 2 years and 1.2% thereafter in male patients, but no gouty arthritis appeared in female patients. Although the annual number of gouty attacks was 2.0+/-4.2 greater than 2 years before the start of dialysis, and 1.9+/-6.6 less than 2 years before the start of dialysis, the annual number of attacks decreased significantly after the start of dialysis to 0.2+/-0.7 in the first 2 years and 0.1+/-0.6 thereafter.
The frequency of gouty arthritis in Japanese patients with ESRD is similar to that of patients with hyperuricemia in the general population and it is decreased slightly before dialysis; however, the frequency decreases markedly after dialysis.
