【Objective】 To compare the efficacy of double filtration plasmapheresis(DFPP), centrifugal therapeutic plasma exchange(cTPE) and centrifugation-filtration plasmapheresis(CFPP) in improving renal insufficiency after kidney transplantation, as well as the differences in inducing plasma exchange-related adverse reactions. 【Methods】 Clinical data from 46 patients who underwent plasma exchange after renal transplantation in our hospital were retrospectively collected, and patiens were divided into DFPP group(n=33), cTPE group(n=7) and CFPP group(n=6). Changes in peripheral blood creatinine, albumin, hemoglobin, platelets, fibrinogen levels and urine volume before and after TPE were compared and analyzed among the three groups. 【Results】 Among the DFPP group, cTPE group and CFPP group, the creatinine after TPE decreased by (31.40±25.38)%, (58.91±19.75)% and (39.44±28.64)%, respectively, with cTPE group significantly higher than the DFPP group(P<0.05), but no significant differences between the DFPP group and cTPE group(P>0.05); the urine volume after TPE increased by (49.33±30.03)%, (54.62±39.32)% and (68.89±23.00)%, showing no significant differences(P>0.05); the hemoglobin after TPE decreased by (11.97±5.94)%, (20.17±5.75)% and (9.65±8.75)%, respectively, with the cTPE group significantly higher than the DFPP group and CFPP group(P<0.05), but no significant difference between the DFPP group and CFPP group(P>0.05). The platelet count after TPE decreased by (37.88±18.39)%, (24.56±12.36)% and (21.40±12.51)%, respectively, with no significant differences between the three groups(P>0.05); the fibrinogen after TPE decreased by (0.57±0.20)%, (0.14±0.06)% and (0.26±0.22)%, respectively, with the DFPP group significantly higher than the cTPE group(P<0.05), but the CFPP group had no significant difference with cTPE group or DFPP group(P>0.05); the albumin after TPE decreased by (11.41±5.97)%, (14.67±6.52)% and (25.18±5.10)%, respectively, with cTPE group and DFPP group significantly lower than the CFPP group(P<0.05, P<0.001), but with no significant difference between the DFPP group and cTPE group(P>0.05). 【Conclusion】 The effect of three plasma exchange methods varies on renal function, anemia and coagulation function of patients after kidney transplantation. It is necessary to consider the the patient’s disease characteristics and treatment needs, as well as the laboratory′s technical conditions and plasma supply when selecting TPE methods.
