Abstract
AIM: The aim of this study was to describe the baseline characteristics of autosomal-dominant polycystic kidney disease (ADPKD) in a cohort of Korean patients with chronic kidney disease (CKD). METHODS: From April 2011 to February 2016, patients with CKD stage 1-5 (pre-dialysis) were enrolled as an ADPKD sub-cohort of the KoreaN Cohort Study for Outcomes in Patients With Chronic Kidney Disease. Baseline characteristics, the correlation of kidney and liver volume and kidney function and the factors associated with kidney function were analysed. RESULTS: A total of 364 ADPKD patients with a mean estimated glomerular filtration rate (eGFR) of 68.1 ± 33.3 mL/min per 1.73 m2 (50.5% male with a mean age of 47.0 ± 10.6 years) were enrolled from nine hospitals in Korea. Initially, 55.8% of the patients were asymptomatic, and pain was the most common symptom (12.9%); 87.6 and 77.5% of the patients had hypertension and hepatic cysts, respectively. The height-adjusted total kidney volumes (htTKV) were higher in male patients than in female patients. In contrast, the height-adjusted total liver volumes were higher in female patients than in male patients. The decrease rate of eGFR depending on Log(htTKV) was larger in the group aged between 41 and 50 years than the other age groups. Older age, a higher 24-h urine protein excretion, larger htTKV and hyperuricemia were independently associated with lower eGFR, whereas using febuxostat was independently associated with higher eGFR. CONCLUSION: This sub-cohort will provide clinical characteristics and outcomes of Korean ADPKD patients, which can be compared with those of other previous cohorts. We have identified factors associated with advanced-stage CKD in Korean patients with ADPKD.
