    Advance care planning (ACP) is a process of shared decision-making about future health-care plans between patients, health care providers, and family members, should patients becomes incapable of participating in medical treatment decisions. ACP discussions enhance patient's autonomy, focus on patient's values and treatment preferences, and promote patient-centered care. ACP is integrated as part of clinical practice in Singapore and the United States.

    Living-kidney transplantation increases with years, however, the rate is comparatively low to support local needs. Marginal living donors like the elderly were used to increase the donor pool. We retrospectively evaluate the outcome of 25 elderly living kidney donors (eLKDs) who were ≥60 years old at the time of donation in our center. Their medical history and laboratory results were analyzed retrospectively from e-medical records. There are 16 females (64.0%) with a median age of 63 (60.5-66.0). The mean follow-up duration was 4.36 ± 2.46 years. Their mean body mass index increased from 23.70 ± 3.07 kg/m2 to 24.21 ± 2.93 kg/m2 (t[14] = -2.176, P = .047) post donation. Systolic blood pressure (SBP) increased from 133.33 ± 11.65 mm Hg to 140.56 ± 17.78 mm Hg (t[17] = -2.124, P = .049). However, the prevalence of overweight and hypertension were not significant. Only 5.56% of the eLKDs developed proteinuria post nephrectomy (P =1.000). Serum creatinine increased from 62.33 ± 14.39 mmol/L to 104.63 ± 28.53 mmol/L post 1-month donation (t[23] = -9.720, P = .000) and decreased to 99.67 ± 22.39 mmol/L post 1-year donation (t[17] = -8.415, P = .006), and latest results were 94.28 ± 20.74mmol/L (t[17] = -6.630, P = .033). Fasting blood glucose and HbA1c level recorded no significant changes post donation. We noted that 47.62% of the eLKDs had dyslipidemia pre donation, which increased to 76.20% post donation (P = .031). eLKDs with hyperuricemia increased significantly from 5.88% to 52.94%; with uric acid level from 306.12 ± 68.67 umol/L to 412.24 ± 74.14 umol/L (t[16] = -7.726, P = .000). None of the eLKDs were diagnosed with metabolic syndrome pre and post kidney donation. Postdonation kidney function of the eLKDs compensated well and were stable in the short term. We noted statistically significant increments of weight, body mass index, SBP, uric acid, and lipid levels, which did not translate to clinical significance post donation. Elderly living-kidney donation can be done safely with close monitoring post donation.
  3. The Effects of Different Induction Regimes on Serial Lymphocyte Subsets in Kidney Transplant Recipients: A Single Tertiary Center Experience

    BACKGROUND: Immunosuppressive therapy is the backbone of kidney transplantation in preventing acute rejection. T-cell depletion after doses of thymoglobulin is dose-dependent, as are their side effects. At the same time, basiliximab and other maintenance immunosuppressive drugs act at different signals on T lymphocytes. Therefore, studying the pattern of lymphocyte subset depletion depending on the induction regime given at transplantation could be an added tool in managing post-transplant recipients.

    METHODOLOGY: This prospective observational study recruited kidney transplant recipients from August 2019 through April 2021 at the University of Malaya Medical Centre. Blood tests for lymphocyte subsets were taken at pre-transplant, 1 week, 1 month, 3 months, and 6 months post-transplantation. At transplantation, recipients received either basiliximab, low-dose thymoglobulin (cumulative dose: 1.5 mg/kg), or standard-dose thymoglobulin (cumulative dose: 5 mg/kg).

    RESULTS: A total of 39 patients were recruited: 38.5% received basiliximab (15 of 39), 15.4% received low-dose thymoglobulin (6 of 39), and 46.2% received standard-dose thymoglobulin (18 of 39). Absolute lymphocyte counts 1 week post-transplantation were 1.5 ± 0.84 × 109/L for basiliximab, 0.7 ± 0.57 × 109/L for low-dose thymoglobulin, and 0.1 ± 0.08 × 109/L for standard-dose thymoglobulin (P < .001). The CD4+ and CD8+ counts were severely depleted in the standard-dose thymoglobulin group, with a statistically significant differenceup to 6 months post-transplantation. In the low-dose thymoglobulin group, the CD4+ and CD8+ counts were depleted at 1 week post-transplantation and recovered at 1 month post-transplantation. There was no difference in allograft function and incidence of allograft rejection across groups.

    CONCLUSIONS: The effects on lymphocyte counts, CD4+ and CD8+, vary depending on the type and dose of induction immunosuppression. This could be a guiding tool in managing immunosuppression post-transplantation depending on the patient's immunologic risk.
