Objective: To evaluate the effects of lipid microspheres coated with prostaglandin E1 (lipo-PGE1) on peritoneal transport function and inflammation in patients with end-stage renal disease undergoing continuous ambulatory peritoneal dialysis (CAPD)., Methods: In total, 89 patients were randomly allocated to the lipo-PGE1 and control groups. All the patients received conventional treatment, and those in the lipo-PGE1 group received lipo-PGE1 intravenously for 2 weeks. The levels of β2-microglobulin (β2-MG), cystatin C, albumin, urea, creatinine, interleukin-6 (IL-6), matrix metalloproteinase-2 (MMP-2), and high-sensitivity C-reactive protein (hs-CRP) were measured before and at 1 and 2 weeks after treatment., Results: In the lipo-PGE1 group, the peritoneal clearance rates of β2-MG, cystatin C, and albumin were significantly increased comparing with pre-treatment values, and the IL-6 appearance rate (AR) in the peritoneal dialysate and the serum levels of IL-6 and hs-CRP were markedly decreased (p < 0.05). The lipo-PGE1 group had significantly higher peritoneal clearance rates of β2-MG and cystatin C and lower IL-6 AR in the peritoneal dialysate than the control group (p < 0.05)., Conclusions: Lipid microspheres coated with prostaglandin E1 may increase the peritoneal clearance of moderately sized molecules and macromolecules with insignificant effect on the clearance of small molecules. The reduction in IL-6 level following treatment with lipo-PGE1 may alleviate inflammation., (© 2021 Wiley Periodicals LLC.)

Introduction: Fatigue is a common but often overlooked symptom in dialysis patients. Factors affecting fatigue in dialysis patients are currently unclear. There are few studies on the effects of mental factors and dialysis modality on fatigue. This study aims to explore the potential relationship between fatigue and insomnia, as well as psychiatric disorders such as anxiety and depression among patients who undergo peritoneal dialysis (PD) or hemodialysis (HD). Methods: There were 96 HD patients and 160 PD patients at our hospital who voluntarily participated in the survey. A questionnaire survey was conducted to gather general characteristics of the patients and to evaluate fatigue, sleep quality, anxiety, and depression levels among PD and HD patients. Results: The overall fatigue score was 53.83 ± 14.22 for the PD group and 57.92 ± 16.35 for the HD group. Notably, the fatigue level was lower in the PD group compared to the HD group (p < 0.05). Univariate analysis indicated that fatigue was associated with occupational status and income in the PD group, as well as educational level and income in the HD group (p < 0.05). Correlation analysis revealed that patients in both groups who were older and had higher scores for insomnia, anxiety, and depression experienced more severe fatigue. Moreover, body mass index was positively correlated with fatigue status in the PD group, while duration of dialysis showed a positive association with fatigue in the HD group. Multivariate regression analysis identified income and depression as major factors influencing fatigue in the PD group, and duration of dialysis, income, and depression in the HD group. Conclusion: Patients who undergo dialysis exhibit high levels of fatigue, with the severity of fatigue being less pronounced in the PD group compared to the HD group. Fatigue in these patients is associated with the duration of dialysis, income level, and presence of depression. [ABSTRACT FROM AUTHOR]
