Clinical characteristics of 103 patients with autosomal dominant polycystic kidney disease / 中华肾脏病杂志

ABSTRACT

Objective:To explore the clinical characteristics of autosomal dominant polycystic kidney disease (ADPKD).Methods:Clinical data of 103 patients with ADPKD first admitted to Renmin Hospital of Wuhan University from July 2017 to April 2021 were retrospectively analyzed. The clinical characteristics of patients in different renal function stages were analyzed, and multiple linear regression analysis was used to analyze the factors reflecting the severity of the disease.Results:Among the 103 patients with ADPKD, there were 49 males (47.6%), aged (51.23±10.99) years old. The extrarenal manifestation was mainly polycystic liver (64/71). The main clinical symptoms were gross hematuria (25 cases, 24.3%), lumbar distend and pain (37 cases, 35.9%) and hypertension (69 cases, 67.0%), appearing in the whole course of the disease. Early treatment was mainly drug conservative treatments (58 cases, 56.3%), followed by renal cyst aspiration (34 cases, 33.0%), and surgical treatments (11 cases, 10.7%). Patients in chronic kidney disease (CKD) stage 5 were mainly treated with conservative treatments (28/34). Laboratory examination results showed that hemoglobin, platelet, lymphocyte percentage and albumin in CKD stage 4-5 were lower than those in CKD stage 1-3 (all P<0.05) ; prothrombin time (PT), PT-international standardized ratio and plasma osmotic concentration in CKD stage 4-5 were higher than those in CKD stage 1-3 (all P<0.05). Multiple linear regression analysis showed that hemoglobin ( β=0.249, P=0.005), platelet ( β=0.207, P=0.005), lymphocyte percentage ( β=0.305, P<0.001) and plasma osmotic concentration ( β=-0.362, P<0.001) were correlated with estimated glomerular filtration rate. Conclusions:The clinical manifestations of ADPKD patients are hypertension, lumbar distend and pain, and gross hematuria, which can run through the whole stage of CKD. Polycystic liver is more common in extrarenal system. Hemoglobin, platelets, lymphocyte percentage and concentration osmotic concentration may be related to the disease progression of ADPKD.
