title: Outcomes of spousal versus related donor kidney transplants: A comparative study.
abstract: This study was designed to compare the outcomes of spousal donor (SD) with related donor (RD) kidney transplants performed at our center between January 2010 and October 2012. A total of 323 adult, ABO-compatible kidney transplants (SD 150 [46.4%], RD 173 [53.6%]) were included. Data on outcomes at 6 months post-transplant was collected retrospectively (2010-2011) and prospectively (January-October 2012). Majority of the donors (SD 88%, RD 72.2%) were females. In the SD group, donors were younger (SD 35.6 ± 8.2 years, RD 45.2 ± 11.5 years; P < 0.0001), whereas recipients were older (SD 42.2 ± 8.3 years, RD 30.0 ± 9.5 years; P < 0.0001). A significantly higher proportion of patients in the SD group were given induction therapy (43% vs 12%; P < 0.001). Biopsy proven acute rejections were more common in the RD group (16% vs 28.3%; P = 0.01). Majority (80.8%) of the acute rejections occurred in the first 2 weeks post-transplant in both groups. Isolated acute cellular rejections (ACRs) and isolated antibody mediated rejections constituted 50% and 25% of rejection episodes in both groups, whereas the remainder had histological evidence of both. The proportion of steroid responsive ACRs was similar in both groups (SD 83.3%, RD 65.4%; P = 0.2). The number of patients with abnormal graft function at the end of the study was higher in the RD group (2.3% vs. 12.3%; P = 0.001). Patient survival and infection rates were similar in the two groups. We conclude that short-term outcomes of SD transplants are not inferior to RD transplants. Lesser use of induction therapy in the RD group may explain the poorer outcomes as compared to the SD group.
