title: The 1998 report of the Japanese National Registry data on pediatric end-stage renal disease patients.
abstract: We carried out a nationwide survey on patients less than 20 years of age with pediatric chronic end-stage renal disease (ESRD) in Japan for the year 1998. There were 582 patients who had started on renal replacement therapy before 1998, and 105 patients who had been newly introduced to renal replacement therapy in that year. The prevalence rate of the ESRD patients already on treatment was 22 per million population (aged 0-19 years) in 1998. Older patients had a higher prevalence rate than younger ones. There were 345 patients on dialysis as of 1 January 1998, and 237 patients with transplants. The major diseases causing ESRD were renal hypoplasia/dysplasia and focal segmental glomerulosclerosis. Of the 237 patients (46.9%) who had received renal transplants before 1 January 1998, 262 patients (96%) received their transplants from living kidney donors. The incidence rate for the new ESRD patients was 4 per million population (aged 0-19 years) in 1998. Older patients had a slightly higher incidence rate than younger ones. Peritoneal dialysis was used more frequently than hemodialysis under 15 years (85%-95% and 39% respectively), especially in very young patients. The major diseases causing ESRD were the same as in the patients already on treatment. The transplant rate for the year 1998 was 10 per 100 dialysis patient-years (patients aged 0-19 years) with 9 living kidney donors. The death rate was 15.6 per 1,000 dialysis patient-years (patients aged 0-19 years); the major causes of death being cardiovascular diseases and infections.
