[Diagnostic Efficacy of Platelet-Related Parameters on Anxiety and Depression in Patients Undergoing Peritoneal Dialysis].

Objective To analyze the correlations between platelet-related parameters and the incidence of anxiety and depression in the patients undergoing peritoneal dialysis(PD),and evaluate the efficacy of the parameters in the diagnosis of anxiety and depression in PD patients. Methods A total of 245 patients undergoing PD in the First Affiliated Hospital of Hebei North University from September 2022 to February 2023 were enrolled.The generalized anxiety scale(GAD-7) and the patient health questionnaire(PHQ-9) were used to evaluate the anxiety and depression of the patients,respectively.The personal information and biochemical indicators of the patients were collected,and the platelet count(PLT),mean platelet volume(MPV),and platelet distribution width(PDW) were measured.Logistic regression was adopted to analyze the relationships of platelet-related parameters with anxiety and depression in PD patients. Results Among the 245 patients undergoing PD,the incidences of anxiety and depression were 15.9% and 38.0%,respectively.There were differences in the dialysis period( Z =-2.358, P =0.018; Z =-3.079, P =0.002),MPV( Z =-4.953, P <0.001; Z =-7.878, P <0.001),and PDW( Z =-4.587, P <0.001;Z=-7.367, P <0.001) between the anxiety group and the non-anxiety group as well as between the depression group and the non-depression group.The correlation analysis showed that MPV( r =0.358, P <0.001; r =0.489, P <0.001) and PDW( r =0.340, P <0.001; r =0.447, P <0.001) were positively correlated with anxiety and depression in the patients undergoing PD.The Logistic regression model showed that MPV( P =0.022, P =0.011),PDW( P =0.041, P =0.018),and dialysis period( P =0.011, P =0.030) were independent risk factors for the anxiety and depressive state in PD patients.The areas under the receiver operating characteristic curve of MPV in the diagnosis of anxiety and depression in PD patients were 0.750 and 0.800,respectively,and those of PDW were 0.732 and 0.780,respectively. Conclusion MPV and PDW have high efficacy in the diagnosis of anxiety and depression associated with PD and can be used as objective indicators to evaluate the anxiety and depression in the patients undergoing PD.
