Abstract：Objective To observe the pulmonary congestion (PC) and quality of life (QOL) in maintenance peritoneal dialysis (MPD) patients and to investigate the relationship between them.Methods We collected the clinical data of 105 MPD patients,evaluated PC with B-line number on pulmonary ultrasonography,evaluated QOL by concise health questionnaire (SF-36),and calculated the physical health score (PCS) and mental health score (MCS).The association between B line number and PCS,MCS was examined by Spearman correlation analysis.Patients were respectively divided into two groups according to the median of PCS and MCS.Demographic data and clinical parameters were compared between the two groups,and then multivariate binary logistic regression analysis was applied to determine the independent risk factors for QOL.Results A total of 105 MPD patients were included.Median B line number was 4 (0,17).PC was detected in 52 cases,PCS was 52.8 (44.8,59.8) points,and MCS was 54.5 (46.8,60.8) points.B line number was negatively correlated with PCS and MCS (r =-0.589,-0.464,both P ＜ 0.01).Compared with patients with high PCS,B lines number,serum B-type natriuretic peptide,average age,proportion of diabetic kidney disease and proportion of previous cardiocerebrovascular events were higher (P ＜ 0.05),while hemoglobin and serum albumin were lower in patients with low PCS (both P ＜ 0.01).Compared with patients with high MCS,B line number and serum B-type natriuretic peptide were higher (both P ＜0.01),but hemoglobin and serum albumin were lower in patients with low MCS (both P ＜0.01).Multivariate analysis showed that B line number,hemoglobin,age,and previous cardiocerebrovascular events were independent risk factors for PCS (all P ＜ 0.01),however,only B line number and hemoglobin were independent risk factors for MCS (both P ＜ 0.05).Conclusion MPD patients have high prevalence of PC and low level of QOL,and PC may be an important reason for the decline of QOL in these patients.
