- Abstract
- Background. Among foreigners undergoing kidney transplantation (KT) in Korea, Mongolians are the most common, and most of these cases are conducted at our center. We report the immunologic characteristics and clinical outcomes of these patients. Methods. Consecutive Mongolian patients who underwent KT from September 2009 to August 2017 in our center were retrospectively analyzed. Pre- and post-transplant HLA antibody status and clinical data of the Mongolian patients were collected and compared with the Korean patients who underwent living donor KT during the same period. Results. Sixty-two Mongolian and 85 Korean patients received KT and were followed up for 20.9 and 50.8 months (P = .01), respectively. Before transplantation, 17.7% of the Mongolian patients and 7.1% of the Korean patients were highly sensitized (P = .05). The patients were monitored consistently throughout the entire post-transplant period. Follow-up loss occurred in some cases. Of the patients, 32 Mongolian patients and 79 Korean patients were monitored for post-transplant HLA antibodies at any time point. Estimated glomerular filtration rates were comparable between Mongolian and Korean patients at 1 month (77.1 vs 71.5 mL/min/1.73m(2), P = .21) and 1 year (64.6 vs 68.7 mL/min/1.73m(2), P = .25) after transplantation but tended to be different at 3 years (57.2 vs 67.3 mL/min/1.73m(2), P = .06) and 5 years (56.9 vs 73.1 mL/min/1.73m(2), P = .04) post transplant. Conclusions. Mongolian patients undergoing KT in Korea were often highly sensitized. Mean follow-up time was short and follow-up loss was common in Mongolian patients compared with Korean patients. Cautious follow-up is needed for foreigner transplant recipients, especially for those at high-risk immunologically, to achieve better outcomes.
