Abstract:
Objective:We employ different regimens of induction therapy in living donor ABO-incompatible kidney transplantation(ABOi-KT) recipients to compare their clinical outcomes during 6 months post-KT.Methods:A retrospective analysis was conducted for the relevant clinical data of 41 ABOi-KT recipients from June 2018 to September 2022.Thirteen recipients on induction therapy of anti-human T lymphocyte porcine immunoglobin(pATG)were enrolled in pATG group; 19 recipients on induction therapy of basiliximab in basiliximab group; 9 recipients on induction therapy of rabbit anti-human thymocyte immunoglobulin(rATG)in rATG group.Differences in age, gender, body mass index(BMI), dialysis modality/duration, sideness of donor kidney, frequency of blood group antibody treatment, dose of rituximab, basic blood group antibody titers of IgG/IgM, and the gender and BMI of recipient's donor were compared for three groups.Immune status was assessed by comparing absolute lymphocyte count before pre-treatment and within 6 months post-KT in recipients under different induction regimens among 3 groups by one-way analysis of variance.Transplant kidney function was assessed by comparing the levels of serum creatinine, estimated glomerular filtration rate(eGFR)and serum urea nitrogen using one-way analysis of variance.The incidence of delayed graft function(DGF), acute rejection(AR)and infection was compared among three groups.Results:Regarding baseline profiles, except for donor age pATG group[(60.23±6.10)years]versus basiliximab group[(51.95±6.97)years]was statistically significant( P=0.002), the differences in the remaining parameters were not statistically significant among three groups(all P>0.05). At Day 1/3/7/10/14 post-KT, absolute lymphocyte counts were(0.17±0.07)×10 9/L, (0.27±0.14)×10 9/L, (0.85±0.40)×10 9/L, (1.05±0.56)×10 9/L and(1.10±0.56)×10 9/L in pATG group and(0.69±0.04)×10 9/L, (0.18±0.21)×10 9/L, (0.57±0.44)×10 9/L, (0.67±0.45)×10 9/L and(0.81±0.46)×10 9/L in rATG group respectively.They were all higher than those in basiliximab group[(0.46±0.18)×10 9/L, (0.67±0.26)×10 9/L, (1.29±0.48)×10 9/L, (1.56±0.49)×10 9/L, (1.75±0.53)×10 9/L]and the differences were statistically significant(all P<0.05). No statistically significant difference existed in absolute lymphocyte count among 3 groups before pre-treatment and after Day 21 post-KT(all P>0.05). At Week 1/2/4/12/24 post-KT, the differences in serum levels of creatinine and urea nitrogen were not statistically significant( P>0.05). At Month 1/3 post-KT, eGFR was(47.24±14.51)and(49.94±14.31)ml·min -1·(1.73 2) -1 in rATG group and they were lower than(67.36±21.60)and(65.00±14.67)ml·min -1·(1.73 2) -1 in basiliximab group with a statistically significant difference( P<0.05). However, at Week 1/2/24 post-KT, no statistically significant difference existed in eGFR among 3 groups( P>0.05). In ATG, basiliximab and rATG groups, DGF(1 case, 1 case, 1 case), AR(2 cases, 2 cases, 1 case)and infection(4 cases, 7 cases, 3 cases)occurred during 6 months post-KT. Conclusions:Through a limited sample of single centers, no statistically significant difference existed in graft function recovery for ABOi-KT recipients on induction therapies of pATG, basiliximab and rATG.And DGF, AR and infections occurred in all three groups.However, there were little inter-group differences.
