Background
Besides the low molecular weight(LMW) solutes, macromolecule such as proteins can also be transported from plasma to peritoneal cavityin peritoneal dialysis(PD). Prostaglandin E1 incorporated in lipid microspheres (Lipo-PGE1) is a potent vasodilator. It was shown to protect vascular endothelial cellsand inhibit the infiltration of inflammatory cells. The aim of this study was to investigate the effect of Lipo-PGE1 on peritoneal transport function and micro-inflammatory state in PD patients.
Methods
We recruiteda total of 89 CAPD patients in the Third Xiangya Hospital from January 2015 to January 2017. Patients were divided into 2 groups, namely the experimental group (Lipo-PGE1 group,n=46) and the control group (not treated with Lipo-PGE1,n=43). The MTACs of urea and creatinine were regarded astheindexes for the transport of LMW solutes. Peritoneal clearances of β2-microglobulin, cystatin C,and albumin were taken asthe indexes to evaluate peritoneal macromolecule transport. IL-6 appearance rate(AR)in the PD effluent, serumIL-6, and hs-CRP were the inflammatory indicators.
Results
The results in the same group before and after2-week treatment showed that: in the experimental group, peritoneal clearances of β2-microglobulin，cystatin C and albumin increased significantly(P<0.05); IL-6 AR, serum IL-6 and hs-CRP level decreased obviously (P<0.05); The MTACs of urea and creatininehave no statistical significance (P>0.05). In the control group, after 2-week treatment, all above indexes have no statistical significance (P>0.05). Thecomparison between two groups showed that: in the experimental group, peritoneal clearance of β2-microglobulin and cystatin C are significantly higher than that in the control group (P<0.05). Peritoneal clearance of albumin, MTAC urea，and MTAC creatinine are also higher than that in the control group, but with no statistically significant difference (P>0.05). IL-6 AR are obviously lower than that in the control group (P<0.05); Serum IL-6 and hs-CRP are also lower than that in the control group, but with no significant difference (P>0.05).
Conclusion
Lipo-PGE1 significantly increases peritoneal transport of macromolecules. Lipo-PGE1 can decrease inflammatory cytokines IL-6 concentration, and reduce micro-inflammatory state in CAPD patients, especially peritoneal cavity local inflammation response.
