*Purpose: Cell free DNA(cfDNA) was widely used in field of cancer and obstetric care. Alloantigens was existed in Organ transplantation, so donor derived cfDNA(ddcfDNA) was now reported in the kidney transplantation. Now we aimed to explore the ddcfDNA level in different type of acute rejection in kidney transplantation.
*Methods: From December 2017 to August 2018, 10 biopsy-proved Banff’s type I acute rejection and 8 biopsy-proved acute humoral rejection kidney transplant patients were included in this study. When the patients experienced biopsy-proved rejection, periphery blood was obtained to identify the ddcfDNA level.
*Results: HLA mismatch was 1.8±1.1 in type I acute rejection group, 2.5±0.9 in acute humoral rejection group, p=0.179; Donor type(DCD/living) was 6/4 in the former group and 4/4 in the latter group, p=0.671; Year of patient age was 33.7±11.5 in type I acute rejection group, and 32.8±9.4 in acute humoral rejection group, p=0.853; Sex (male/female) was 3/7 in former group, 6/2 in latter group, p=0.058; The percentage of peripheral ddcfDNA level was 0.78±0.51 in type I acute rejection group, significantly lower than that 2.04±0.84 in acute humoral rejection group, p=0.001.
*Conclusions: Acute humoral rejection had significantly higher periphery ddcfDNA level when compared to type I acute rejection in kidney transplantation.
