ABSTRACT
Objective:
To explore the risk factors related to hospitalization events in out patients on hemodialysis and to evaluate the effect of serum retinol-binding protein (RBP) level on hospitalization events in patients on hemodialysis.Methods:
Case-control study. A total of 80 patients on dialysis were recruited, including 47 men (58.8%) and 33 women (41.2%), with an average age of (60.9±11.7) years (range 32-89 years) and a median dialysis age of 43.6 months. Dialysis-related data were collected, the serum RBP level was detected using the ELISA method. Patients were followed-up until June 30, 2019, to record the events associated with all kinds of hospitalization events. The t-test, Mann-Whitney U test and chi-square test were used to compare the differences between the hospitalized event group and the non-event group. Multivariate logistic regression was used to analyze the related risk factors of hospitalization events. The Kaplan-Meier method, Log-rank test, and Cox proportional hazards regression model were used to analyze survival data.Results:
During the 19-month follow-up period, 26/80 patients (32.5%) had 67 events of hospitalization. There was no difference ( P>0.05) in age, sex composition, dialysis age, ratio of diabetes/hypertension, interval dialysis weight gain (IDWG), systolic/diastolic blood pressure before dialysis, kt/v and URR between the groups with or without hospitalization events. The cut-off point of serum RBP was calculated using the patient′s highest Youden index. The patients were divided into the high-RBP group ( n=44) and low-RBP group ( n=36) according to the level of 165.34 mg/L. The incidence of hospitalization events in the high-RBP group was higher than that in the low-RBP group (45.45%>16.67%, P=0.006). Using the multivariate logistic regression model, after adjusting for sex, age, albumin and total cholesterol (CHO), only the serum RBP level was independently correlated with hospitalization events. The high-RBP group had an odds ratio ( OR) of 3.64 (95 %CI, 1.14-11.58; P=0.029) compared with the low-level group in hospitalization events. The Kaplan-Meier survival analysis showed that the incidence of hospitalization events in the high-RBP group was significantly higher than that in the low-RBP group ( P=0.0058). The test results of the multivariable Cox proportional hazards regression model showed that for patients on hemodialysis, an elevated serum RBP level is an independent risk factor for hospitalization events.Conclusion:
Elevated serum RBP level is correlated with hospitalization events in patients on hemodialysis. RBP is an independent risk factor for hospitalization events in outpatients on hemodialysis.
