    BACKGROUND: In-depth understanding of cultural and religious factors limiting organ donation of three ethnic populations (Malay, Chinese, and Indian) in Southeast Asia is lacking. Identification of factors limiting organ donation among these three ethnic groups will provide insights into culturally appropriate strategies to promote acceptance of organ donation in a multiethnic Asian community.
    METHODS: A total of 17 focus group discussions (105 participants) were conducted between September and December 2008. Participants were members of the general public aged 18 to 60 years, recruited through convenient sampling around the Klang Valley area of Malaysia.
    RESULTS: Although the majority had favorable attitudes toward deceased organ donation and transplantation, a diversity of myths and misinformation were unearthed from the discussions across the ethnic groups. These include perceived religious prohibition, cultural myths and misperceptions, fear of disfigurement, fear of surgery, distrust of the medical system, and family disapproval. Culture and religious beliefs played important prohibitive roles among those opposed to organ donations. There were distinctive ethnic differences in cultural and religious concerns regarding organ donation. Less-educated and rural groups appeared to have more misconceptions than the well-educated and the urban groups.
    CONCLUSION: Our findings may assist organ donation and transplantation organizations to reach diverse sociodemographic and ethnic communities with culture-specific information about organ donation. The involvement of community and religious leaders is critical in organ donation requests.

    Bioelectrical impedance analysis was introduced more than a decade ago to measure body composition and nutritional status. There are presently limited data on the nutritional status and body composition measured with bioelectrical impedance analysis in renal transplant recipients, especially among the Asian population. The normal values for these data in renal transplant recipients remain unknown.

    BACKGROUND: The attitudes of the health care workers (HCWs) are essential in influencing organ donation rate. The aim of this study was to assess the effects of an educational intervention on attitudes toward organ donation among HCWs.

    METHODS: A questionnaire-based interventional study was conducted with 458 HCW from 5 hospitals in Malaysia. A 26-item self-administered questionnaire was distributed online as a preintervention test. Respondents then went through website-based educational materials followed by a post-intervention questionnaire.

    RESULTS: A total of 345 (75.3%) respondents completed the tests. Their attitude toward organ donation was positive preintervention. After the intervention, respondents expressed an increase willingness to donate their own organs (P = .008) and their relatives' organs (P < .001) after death; were more willing to adopt organ donation as part of end-of-life care (P =.002); were more comfortable talking to relatives about organ donation (P =.001); and expressed an increase consideration to execute the action at any time (P =.001). There was increased willingness to admit to the intensive care unit for facilitating organ donation (P =.007); to employ the same resources to maintain a potential brain-dead donor (P < .001); and to support organ donation in case they or their relatives were diagnosed with end-stage organ failure (P =.008). However, there was an increase in negative attitudes regarding the association between organ donation with health care failure (P =.004) and with pain (P =.003). Positive attitude scores were higher after the intervention (P < .001).

    CONCLUSION: An educational website-based intervention was able to improve the attitudes of HCWs toward organ donation.

    Delayed graft function is a potentially challenging problem especially in cadaveric kidney transplant recipients. It adversely impacts long-term graft survival. It is rarely seen in living kidney transplants. Recovery of graft function usually occurs within a month. The chances of recovery of graft function diminish with further prolongation of delayed function. In fact, recovery of graft function after 3 months has rarely been described, we report herein recovery of graft function after 132 days of nonfunction in a living related kidney transplant.

    BACKGROUND: Evaluation of donor renal function as glomerular filtration rate (GFR) is a crucial part of pretransplant workup. Most guidelines recommend measured GFR (mGFR) using exogenous markers with creatinine clearance (CrCl) as an alternative. However, exogenous markers are difficult to obtain and perform, and CrCl may overestimate GFR.

    OBJECTIVE: We explore the use of CrCl and combined urea and creatinine clearance as an alternative for GFR assessment.

    METHODS: A retrospective study involving 81 kidney donors from 2007 to 2020, with mGFR collected by chromium 51-labeled ethylenediaminetetraacetic acid (51Cr-EDTA) and CrCl and combined urea and creatinine clearance. We analyzed the performance of CrCl and combined urea and creatinine clearance against 51Cr-EDTA. Adequacy of urine volume was taken into consideration.

    RESULTS: A total of 81 candidates with a mean age of 44.80 ± 10.77 years were enrolled. Mean mGFR from 51Cr-EDTA was 123.66 ± 26.91 mL/min/1.73 m2, and combined urea and creatinine clearance and CrCl were 122.13 ± 47.07 and 133.40 ± 36.32 mL/min/1.73 m2, respectively. CrCl overestimated 51Cr-EDTA. Though combined urea and creatinine clearance had minimal bias, it had a lower correlation coefficient (0.25 vs 0.43), lower precision (49.51 vs 38.10), and slightly lower accuracy within 30% of 51Cr-EDTA (74.07% vs 76.54%).

    CONCLUSIONS: Combined urea and creatinine clearance did not improve the performance of CrCl. Nevertheless, it can potentially be used as first-line GFR assessment, followed by mGFR in selected donors, to ascertain threshold of safe kidney donation. A stringent urine collection method is essential to ensure accurate measurement.

    Catheter angiography is traditionally used to determine renal arterial anatomy in live renal donors. Three-dimensional (3D) contrast-enhanced magnetic resonance imaging (MRA) has been suggested as a noninvasive replacement. We assessed the possibility of using MRA in live renal donors in Malaysia.

    Promising outcomes of kidney transplantation following hematopoeitic stem cell transplantation has been reported. Data from some centers have demonstrated stable graft function without long term immunosuppression. We present our experience with the first successful case in Malaysia. This is a 21-year-old man who had acute myeloid leukemia, received stem cell transplant from his younger brother 8 years prior, underwent kidney transplantation from the same donor, and had an excellent 1-year graft function post-transplant. As the post-transplant genetic analysis revealed full chimerism, his immunosuppression regimen can be tapered to minimal doses safely. The concept of immunotolerance is now widely studied and could potentially be the curative strategy for patients who develop end stage kidney disease after hematopoeitic stem cell transplantation.

    The Asian Society of Transplantation, founded in 1989 includes Indonesia, Japan, Korea, Malaysia, Oman, Pakistan, Republic of China, Philippines, Saudi Arabia, Singapore, Taiwan, Thailand, and the United Arab Emirates (UAE). The registry was also started from the same year in cooperation with these 16 countries. A questionnaire was sent to the key person of each country every year. The questionnaire includes (a) number of centers that performed organ transplants, (b) varieties and numbers of organ transplants performed in 2000 and 2001, (c) present status of dialysis, number of dialysis patients, and number of the candidates on the list for transplantation, (d) number of patients going abroad for transplantation, and (e) recent transplant highlights, news and issues affecting each country during 2000 and 2001. We previously gathered data for 2000, except for Indonesia, Singapore, and the UAE. Regarding 2001 data, we will send the questionnaires to the countries involved.

    BACKGROUND: Although metabolic syndrome (MetS) is a significant risk factor, and dietary intake may affect the quality of life (QoL) of kidney transplant recipients (KTRs), the association between them are unclear. This study identified MetS and nutritional factors associated with the QoL of KTRs.

    METHODS: This study reports baseline data from a longitudinal study that was conducted at a hospital in Vietnam. KTRs aged ≥18 years and >3 months post-transplantation were recruited. Assessments included sociodemographic and blood biomarkers. Dietary intake was estimated from 24-hour recalls. A Short Form-36 Health Survey, comprising physical (PCS) and mental component summaries (MCS), was administered to assess QoL. Multivariate linear regression models were performed.

    RESULTS: The study included 106 patients (79 men) with a mean age of 43.2 years (± 11.9). Mean duration after kidney transplantation was 28.5 months (± 14.9). Patients with MetS had 6.43 lower PCS score (P < .05) and 3.20 lower MCS score (P < .05) than their counterparts without MetS. Calcium intake (β = -0.01; 95% CI, -0.03 to 0.00) and inadequate protein (β = -14.8; 95% CI, -23 to -6.65) were negatively associated with PCS score. MCS score was negatively associated with calcium intake (β = -0.02; 95% CI, -0.04 to -0.01) and inadequate protein intake (β = -15.1; 95% CI, -24.3 to -5.86), and positively associated with fat intake (β = 0.43, 95% CI, 0.02-0.85).

    CONCLUSIONS: MetS and poor dietary intake are independently associated with the QoL of KTRs. Nutritional intervention plans developed specifically for the recipients will improve dietary intake, reduce the incidence of MetS, and help enhance QoL.

    BACKGROUND: The Malaysian Kidney Allocation System implemented in 2020 includes only kidney transplant candidates with estimated posttransplant survival (EPTS) score of ≤20%, in replacement of Malaysian Organs Sharing System, which was based solely on dialysis vintage. We aim to compare the clinical outcomes of deceased-donor kidney transplant recipients (DDKTRs) with EPTS ≤20% to those with EPTS >20%.

    METHODS: All DDKTRs between January 1, 2015, and December 29, 2020, were included and categorized into 2 groups: EPTS ≤20% and EPTS >20%. Cox regression was performed to evaluate the association of EPTS score and patient survival. The rate of postoperative complications, graft failure and patient survival were compared between 2 groups. Data were analyzed with SPSS v26 and R v4.0.4. The study complies with the Helsinki Congress and the Istanbul Declaration.

    RESULTS: We included 159 DDKTRs, with a median follow-up of 25 months (range, 10-60 months). The mean age of those with EPTS ≤20% was 32.2 ± 3.4 years and those with EPTS >20% was 46.0 ± 6.7 years, and the median EPTS score were 16% (range, 12%-18%) and 38% (range, 27%-56.5%), respectively. EPTS score was associated with patient survival (hazard ratio, 1.031; 95% CI 1.010-1.052; P = .003), and the cutoff points of 30% and above were associated with worse survival. It showed good discrimination (C-index, 0.729; 95% CI 0.579-0.878; P = .003) and the optimal cutoff value was 38% (65.5% sensitivity, 68.8% specificity, 17.8% positive predictive value, and 95.8% negative predictive value). Both groups had similar rate of surgical complications (P = .191), graft failure (P = .503), and patient survival (P = .654), but those with EPTS >20% had higher incidence of urinary tract infection (9.3% vs 27.6%, P = .016).

    CONCLUSIONS: There was no difference in clinical outcomes using an EPTS cutoff point of 20% but worse patient survival if higher cutoff point was used.

    BACKGROUND: The aim of this study was to compare the within-patient variability trough levels (Co), dose-adjusted Co, and dose requirements of Prograf and Advograf with CYP3A5 polymorphisms in Malaysia renal transplant recipients.
    METHODS: Stable post-renal transplantation patients switched from Prograf to Advograf were retrospectively identified from University Malaya Medical Centre (n = 28). Co and concomitant tacrolimus dose 6 months preconversion and postconversion were examined. CYP3A5 was genotyped using reverse transcriptase polymerase chain reaction. Wilcoxon signed rank test and Mann-Whitney U test were used to compare Co and dose between formulations and according to genotypes.
    RESULTS: There was a significant difference in the whole-blood tacrolimus Co between the 2 groups (6.16 ± 1.74 ng/mL vs 4.90 ± 1.06 ng/mL; P = .0001). The mean daily maintenance dose of Prograf was 3.9 ± 2.0 mg/kg (0.06 mg/kg/d), which was reduced to 3.3 ± 1.7 mg/d (0.04 mg/kg/d) with Advograf (P = .01). The mean maintenance dose of tacrolimus required for those with CYP3A5*1/*1 (high-expressive) was significantly higher than those with CYP3A5*1/*3 (intermediate-expressive) and CYP3A5*3/*3 (low-expressive) (P < .01) for both formulations. Comparing those with CYP3A5*1/*1, the average dose-adjusted Co was significantly higher in patients with CYP3A5*3/*3 with Advograf (P < .05).
    CONCLUSIONS: The requirement for daily maintenance dose was higher in those with CYP3A5*1/*1 variants in both tacrolimus formulations in the Malaysian patients. Furthermore, those with CYP3A5*3/*3 demonstrated significantly higher dose-adjusted Co with Advograf.
