AIM

To compare the efficacy and safety between rabbit anti-thymocyte globulin (Thymoglobulin) and anti-T lymphocyte globulin (ATG-Fresenius, ATG-F) in donation after cardiac death (DCD) kidney transplantation.

METHODS

We retrospectively analyzed 255 cases of DCD kidney transplantation performed at our hospital from February 2007 to October 2013. The patients were divided into two groups based on their induction therapies with Thymoglobulin (n = 188) or ATG-F (n = 67). Clinical data were collected and compared between the two groups.

RESULTS

Delayed graft function (DGF) occurred in 36 (19.1%) patients in the Thymoglobulin group versus 17 (25.4%) patients in the ATG-F group (P = 0.281). However, if we subgroup the patients with increased risk factors for DGF, the DGF rate was 9/40 (22.5%) in the Thymoglobulin group versus 9/16 (56.3%) in the ATG-F group (P = 0.015). Duration of DGF was significantly shorter in the Thymoglobulin group (11.7 days vs. 16.1 days). The acute rejection rate was significantly lower in the Thymoglobulin group (9.6% vs. 19.4%, P = 0.035). One-year graft and patient survival were both comparable between the Thymoglobulin and ATG-F groups. The adjusted odds ratio of DGF was 4.283 (1.137-16.13) between the ATG-F and Thymoglobulin groups in patients with increased risk factors for DGF.

CONCLUSION

Compared with ATG-F, Thymoglobulin may reduce duration of DGF and acute rejection rate after DCD kidney transplantation. Moreover, Thymoglobulin significantly reduced DGF in patients with increased risk factors for DGF.
