简要总结

Heart Transplant recipients at Tampa General Hospital heart transplant program who have pAMR1(H+) or pAMR1(I+) rejection will have a DD-cfDNA /GEP sample obtained at the time of the rejection. The DD-cfDNA/GEP will then be drawn every month post treatment for the rejection until the DD-cfDNA/GEP level returns to normal. A total of fifteen recipients with pAMR1(H+) and fifteen recipients with pAMR1(I+) rejection will be included in the study which will last two years. The presence of HLA antibodies (DSA's) and the titers, presence of Autoantibodies, the measurement of cytokines IL2, IL4, IL6, IL 10, IL 17, TNF alpha, TGF beta, the presence of coronary artery vasculopathy, the time from transplant to the onset of the episode of AMR, time to resolution, the response to treatment and comparison to the DD-cfDNA/GEP level with pAMR2 and pAMR 3 rejections will be analyzed.

结局指标

主要结局

The level of dd-cfDNA in non-compliment mediated pAMR1 (H+) and complement mediated pAMR1 (I+) heart transplant rejection will be measured.

时间窗: 2 years

The level of dd-cfDNA in non-compliment mediated pAMR1 (H+) and complement mediated pAMR1 (I+) heart transplant rejection will be measured and then compared statistically to each other via Students t test as well as to the level of dd-cf DNA before and after the rejection episode.

次要结局

  • The presence of HLA antibodies (DSA's) and titer levels, autoantibodies and titer levels and coronary artery vasculopathy will be measured.(2 years)
