Risk Factors of Acquired Cystic Kidney Disease in Peritoneal Dialysis Patients
Objective:To analyze the clinical characteristics and possible factors of acquired cystic kidney disease(ACKD)in peritoneal dialysis patients.Methods:A total of 110 patients undergoing peritoneal dialysis for at least six months in the Affiliated Hospital of Jiangnan University from February 2021 to February 2022 were enrolled and divided into ACKD group and without ACKD group.The clinical characteristics of acquired cystic kidney disease in peritoneal dialysis patients were analyzed and the possible fac-tors were also analyzed.Results:There were41(37.3%)patients with ACKD and69(62.7%)patients without ACKD.The mean ageinthepatientswith ACKD(58.95±13.64)was greater than in those without ACKD(53.12±11.47).The dialysis time in ACKD patients(36(14.82~60)months)was longer than those without ACKD(24(8.5~32.85)months).PTH in ACKD pa-tients(581(287.5-1200))was also higher than that without ACKD(411(214.5~576.5)).The differences were all statistically significant(P<0.05).But there was no significant difference in gender,BMI,primary affection,history of hypertension and diabe-tes.The level of hemoglobin,creatinine,urea nitrogen,uric acid,albumin,lipids,ferritin,tumor markers(CYFRA,CA199),cal-cium,phosphorum,Kt/V and PET(Peritoneal Equilibration Test)between two groups were also different(P>0.05).Binary logistic regression analysis showed that age,the duration of dialysis,and the level of PTH were risk factors of acquired cystic kidney disease in peritoneal dialysis patients.Patients with older age(OR =1.076,95%CI =1.03~1.125,P = 0.001),longer dialysis time(OR =1.024,95%CI =1.003~1.045,P =0.024),and higher level of PTH(OR =1.002,95%CI =1.00~1.003,P =0.008)are more likely to develop acquired renal cysts.Conclusion:Age and dialysis time have influence on the occurrence of acquired renal cysts in peritoneal dialysis patients.The older age and the longer dialysis time can increase the incidence of acquired renal cysts.The lower PTH level can reduce the occurrence of acquired renal cysts.
