RESUMEN
Introduction: The mortality rate of coronavirus disease 2019 (COVID-19) in kidney transplant recipients (KTR) has significantly decreased with the implementation of vaccination programs. However, the real-world information on the impact of vaccinations, particularly in resource limited settings in Asia, is still limited. Methods: The Thai Transplant Society conducted a prospective multicenter cohort registry, including KTR diagnosed with COVID-19. Cox proportional hazards regression was used to examine factors associated with poor COVID-19 outcomes and complications, including death, COVID-19 pneumonia, and superimposed bacterial infection. Results: A total of 413 patients from 17 transplant centers who developed COVID-19 were analyzed. The COVID-19 mortality rate was 5.6 % and the incidence of pneumonia was 18.8 %. With each 10-year increase in age, the risk of death, pneumonia, and bacterial infection increased by 61 %, 32 %, and 43 %, respectively. A total of 11.4 % of KTR received one dose of COVID vaccination (incomplete vaccination), 25.7 % received two doses (complete primary vaccination), 42.6 % received three doses (first booster dose), and 10.4 % received four doses of vaccination (second booster dose). Even a single dose of vaccination significantly decreased the risk of death, pneumonia, and superimposed bacterial infection among KTR compared to those who remained unvaccinated. Completing the primary vaccination (2-dose) reduced the risk of death by 89 %, pneumonia by 88 %, and bacterial infection by 83 % compared to unvaccinated KTR. Receiving a booster dose (third or fourth dose) further reduced the risk of death by 94 %, pneumonia by 95 %, and bacterial infection by 96 % compared to unvaccinated individuals. Conclusions: This Asian cohort demonstrated that the mortality and complications of COVID-19 significantly decreased in KTR after the national immunization. Our study suggests that any type of COVID-19 vaccine can be beneficial in preventing adverse outcomes. Administering booster vaccinations is strongly recommended.
RESUMEN
The influence of acute kidney injury (AKI) and renal recovery in deceased donor (DD) on long-term kidney transplant (KT) outcome has not previously been elucidated in large registry study. Our retrospective cohort study included all DDKT performed in Thailand between 2001 and 2018. Donor data was reviewed case by case. AKI was diagnosed according to the KDIGO criteria. Renal recovery was defined if DD had an improvement in AKI to the normal or lower stage. All outcomes were determined until the end of 2020. This study enrolled 4234 KT recipients from 2198 DD. The KDIGO staging of AKI was as follows: stage 1 for 710 donors (32.3%), stage 2 for 490 donors (22.3%) and stage 3 for 342 donors (15.6%). AKI was partial and complete recovery in 265 (17.2%) and 287 (18.6%) before procurement, respectively. Persistent AKI was revealed in 1906 KT of 990 (45%) DD. The ongoing AKI in DD significantly increases the risk of DGF development in the adjusted model (HR 1.69; 95% CI 1.44-1.99; p < 0.001). KT from DD with AKI and partial/complete recovery was associated with a lower risk of transplant loss (log-rank P = 0.04) and recipient mortality (log-rank P = 0.042) than ongoing AKI. KT from a donor with ongoing stage 3 AKI was associated with a higher risk of all-cause graft loss (HR 1.8; 95% CI 1.12-2.88; p = 0.02) and mortality (HR 2.19; 95% CI 1.09-4.41; p = 0.03) than stage 3 AKI with renal recovery. Persistent AKI, but not recovered AKI, significantly increases the risk of DGF. Utilizing kidneys from donors with improving AKI is generally safe. KT from donors with persistent AKI stage 3 results in a higher risk of transplant failure and recipient mortality. Therefore, meticulous pretransplant evaluation of such kidneys and intensive surveillance after KT is recommended.

BACKGROUND: This study compared a novel technique for renal allograft biopsy, color Doppler ultrasound-guided biopsy (CDUS-Bx), with routine ultrasound-guided biopsy (RUS-Bx). METHODS: A retrospective review was conducted on 111 patients, with 42 undergoing CDUS-Bx and 69 undergoing RUS-Bx. Urologists used an 18-gauge automatic spring-loaded biopsy needle for all procedures. CDUS-Bx tissue collection was guided by identifying renal vessels with color Doppler mode. RESULTS: Overall, the adequacy rate was 90.1%, with a higher number of glomeruli obtained in the CDUS-Bx group (25.6 ± 10.3 vs. 20.6 ± 11.3, P = .008). Acute tubular necrosis was the most frequent pathological diagnosis, with a higher prevalence in the CDUS-Bx group (69% vs 40.6%). T cell-mediated rejection had a lower incidence in the CDUS-Bx group (4.8% vs 21.7%), and antibody-mediated rejection was comparable between the 2 groups. The most common complication was microscopic hematuria, which was significantly less frequent in the CDUS-Bx group (48.7% vs 70.1%, P = .028), but there was no significant difference in the rate of gross hematuria between CDUS-Bx and RUS-Bx (11.9% vs 11.6%, P = .961). The number of cores was the only predictor of adequate biopsy, with a 93.2% adequacy rate after 3 cores of allograft biopsy. Multivariate analysis revealed that only the guiding type, CDUS-Bx, was associated with less microscopic hematuria (adjusted odds ratio 0.325, P = .018). CONCLUSIONS: Color Doppler ultrasound-guided biopsy had comparable tissue adequacy to RUS-Bx, with a lower incidence of microscopic hematuria. These findings suggest that CDUS-Bx may be a safe and effective alternative to RUS-Bx for allograft biopsy.

PURPOSE OF REVIEW: Lipid disorder is a prevalent complication in kidney transplant recipients (KTRs) resulting in cardiovascular disease (CVD), which influences on patient outcomes. Immunosuppressive therapy demonstrated the major detrimental effects on metabolic disturbances. This review will focus on the effect of immunosuppressive drugs, lipid-lowering agents with current management, and future perspectives for lipid management in KTRs. RECENT FINDINGS: The main pathogenesis of hyperlipidemia indicates an increase in lipoprotein synthesis whilst the clearance of lipid pathways declines. Optimization of immunosuppression is a reasonable therapeutic strategy for lipid management regarding immunologic risk. Additionally, statin is the first-line lipid-lowering drug, followed by a combination with ezetimibe to achieve the low-density lipoprotein cholesterol (LDL-C) goal. However, drug interaction between statins and immunosuppressive medications should be considered because both are mainly metabolized through cytochrome P450 3A4. The prevalence of statin toxicity was significantly higher when concomitantly prescribed with cyclosporin, than with tacrolimus. SUMMARY: To improve cardiovascular outcomes, LDL-C should be controlled at the target level. Initiation statin at a low dose and meticulous titration is crucial in KTRs. Novel therapy with proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, which is highly effective in reducing LDL-C and cardiovascular complications, and might prove to be promising therapy for KTRs with statin resistance or intolerance.

Background: Compared with other kidney replacement therapies, preemptive kidney transplantation (KT) provides better clinical outcomes, reduces mortality, and improves the quality of life of patients with end-stage kidney disease (ESKD). However, evidence related to the cost-effectiveness of preemptive living-related KT (LRKT) is limited, especially in low- and middle-income countries, such as Thailand. This study compared the cost-effectiveness of LRKT with those of non-preemptive KT strategies. Methods: Cost and clinical data were obtained from adult patients who underwent KT at Siriraj Hospital, Mahidol University, Thailand. A decision tree and Markov model were used to evaluate and compare the lifetime costs and health-related outcomes of LRKT with those of 2 KT strategies: non-preemptive LRKT and non-preemptive deceased donor KT (DDKT). The model's input parameters were sourced from the hospital's database and a systematic review. The primary outcome was incremental cost-effectiveness ratios (ICERs). Costs are reported in 2020 United States dollars (USD). One-way and probabilistic sensitivity analyses were performed. Results: Of 140 enrolled KT patients, 40 were preemptive LRKT recipients, 50 were non-preemptive LRKT recipients, and the rest were DDKT recipients. There were no significant differences in the baseline demographic data, complications, or rejection rates of the three groups of patients. The average costs per life year gained were $10,647 (preemptive LRKT), $11,708 (non-preemptive LRKT), and $11,486 (DDKT). The QALY gained of the preemptive option was 0.47 compared with the non-preemptive strategies. Preemptive LRKT was the best-buy strategy. The sensitivity analyses indicated that the model was robust. Within all varied ranges of parameters, preemptive LRKT remained cost-saving. The probability of preemptive LRKT being cost-saving was 79.4%. Compared with non-preemptive DDKT, non-preemptive LRKT was not cost-effective at the current Thai willingness-to-pay threshold of $5113/QALY gained. Conclusions: Preemptive LRKT is a cost-saving strategy compared with non-preemptive KT strategies. Our findings should be considered during evidence-based policy development to promote preemptive LRKT among adults with ESKD in Thailand.
RESUMEN
INTRODUCTION: Differences in transplant characteristics limit the application of kidney donor profile index (KDPI) and estimated post-transplant survival (EPTS) models developed in Western countries to Asian populations. METHODS: We analyzed data of the Thai Transplant Registry and the Thai Red Cross Society on 2558 DDKTs performed between 2001 and 2014. Thai KDPI and EPTS models were developed using Cox regression, and validation against the US models. RESULTS: Thai KDPI was developed based on seven donor factors: age, height, best estimated glomerular filtration rate, diabetes mellitus, hypertension, cerebrovascular accident, and adrenaline infusion. The Thai and US donor risk index had comparable predictive abilities for transplant survival (C-statistics .5871 vs. .5548; P = .429). KTs from donors with a US KDPI > 70% demonstrated significantly worse 5-year transplant survival. The Thai EPTS model was developed from four recipient factors: age, body weight, diabetes mellitus, and hepatitis C infection. The C-statistics of the Thai and US EPTS models were comparable (.5924 vs. .6039; P = .360). A US EPTS > 70% was revealed in only 2.5% of our cohort. CONCLUSIONS: The first simplified KDPI and EPTS models for an Asian population were developed. Our models are available at www.thai-kdpi-epts.org.

BACKGROUND: High intrapatient variability in tacrolimus trough levels (Tac IPV) is associated with poor allograft outcomes. Tac IPV was previously calculated using trough levels 6-12 months after kidney transplantation (KT). Data on the accuracy of Tac IPV calculation over a longer period, the association between high Tac IPV and donor-specific antibody (DSA) development after KT in Asian patients, and the role of IPV in patients receiving concomitant cytochrome P450 (CYP)3A4/5 inhibitors (CYPinh) are limited. METHODS: A retrospective review of patients who underwent KT at our center in 2005-2015, and who received Tac with mycophenolate during the first 2 years after KT was performed. IPV was calculated using Tac levels adjusted by dosage. DSA was monitored annually after KT using a Luminex microbead assay. RESULTS: In total, 236 patients were enrolled. CYPinh were prescribed to 189 patients (80.1%): 145 (61.4%), 31 (13.1%), and 13 (5.5%) received diltiazem, fluconazole, and ketoconazole, respectively. Mean IPV calculated from adjusted Tac levels for 6-12 months (IPV6-12) and 6-24 months (IPV6-24) after KT were 20.64% ± 11.68% and 23.53% ± 10.39%, respectively. Twenty-six patients (11%) showed late rejection and/or DSA occurrence, and had significantly higher IPV6-24 (29.42% ± 13.78%) than others (22.77% ± 9.64%; P = 0.02). There was no difference in IPV6-12 (24.31% ± 14.98% versus 20.17% ± 10.90%; P = 0.18). IPV6-12 and IPV6-24 were comparable in patients who did and did not receive CYPinh. When using mean IPV6-24 as a cutoff, patients with higher IPV6-24 had a higher probability of developing DSA and/or late rejection (P = 0.048). CONCLUSIONS: Tac IPV6-24 was higher and more significantly associated with DSA development and/or late rejection than Tac IPV6-12, independent of Tac trough level. This is the first study to demonstrate the impact of high IPV on DSA development in Asian patients, and that Tac IPV is comparable between patients with and without CYPinh.

BACKGROUND: Chronic active antibody-mediated rejection (CAMR) has unsatisfactory prognosis in spite of intensive standard antihumoral treatment. Efficacy of additional bortezomib in CAMR remains uncertain. METHODS: A retrospective chart review was conducted among kidney transplant patients with biopsy-proven CAMR. Our standard CAMR protocol included plasma exchange, intravenous immunoglobulin, and rituximab. Repeated treatment was provided for refractory cases. Patients receiving at least 1 course of bortezomib were enrolled as the bortezomib group. Allograft outcome was compared among patients receiving repeated standard protocol alone and the bortezomib group. RESULTS: Thirteen and 15 patients were assigned to the bortezomib and control groups, respectively. Repeated bortezomib protocol was given for 1, 2, 3, and 4 courses in 6, 4, 1, and 2 patients, respectively. With a median follow-up time after treatment of 41.8 (18.3-47.4) months, the bortezomib group had a lower rate of glomerular filtration rate declination (-4.20 ± 4.89 mL/min/y vs -12.33 ± 10.44 mL/min/y; P = .014), a higher rate of disappearance of donor specific antibodies (69.2% vs 25%; P = .03), a lower rate of allograft loss (15.4% vs 66.7%; P = .006), and better allograft survival (P = .006). CONCLUSION: In CAMR, additional bortezomib treatment was more effective in eliminating donor specific antibodies and improving allograft survival than standard protocol treatment.

BACKGROUND: Converting to once-daily tacrolimus (Advagraf [Adv]) among renal transplant patients results in better drug adherence. Data regarding dosage and intrapatient variability changes after conversion among patients with CYP3A4/5 inhibitors (CYPinh) is lacking. METHOD: A retrospective chart review among all kidney transplant recipients at Siriraj Hospital was performed. Patients were enrolled who had been on standard release twice-daily tacrolimus and subsequently replaced it with Adv for at least 6 months with no change in CYPinh type or dosage. RESULTS: Fifty-three patients were eligible. Conversion occurred at a mean time after transplant of 51.25 (SD, 40.30) months. Ten patients (18.9%) did not receive CYPinh, while 19 (35.8%), 21 (39.6%), and 3 (5.7%) received diltiazem, ketoconazole or fluconazole, and both diltiazem and ketoconazole, respectively. After conversion, median increment of tacrolimus dosage was 14.29% (-50% to 167%), while no significant change in IPV was demonstrated (17.46% [SD, 11.25%] vs 14.83% [SD, 6.78]; P = .11). Patients receiving azole had less dosage increment than those not receiving CYPinh (P = .02). After conversion, 14 of 22 patients with IPV > 17% (63.6%) had reduced IPV to ≤ 17%, while 25.8% of patients with lower IPV had an increase in IPV > 17%. CONCLUSION: Conversion to Adv required a dosage increment of 30% to achieve the same trough level. Concomitant use of CYPinh significantly reduced tacrolimus dose increment. A trend was noted toward improved IPV after conversion. Conversion to Adv resulted in better IPV among patients with high IPV while receiving twice-daily tacrolimus.

BACKGROUND: Mycophenolic acid (MPA) is one of the main immunosuppressive regimens used after kidney transplantation (KT). The less expensive, generic form of mycophenolate mofetil (MMF) (Immucept®) is recently available in Thailand. Comparisons of the pharmacokinetic profiles between the original and generic forms of MMF among post-KT patients are limited. METHODS: This prospective cohort study recruited KT patients receiving stable doses of MMF 1000 mg daily along with tacrolimus and steroids. All participants were prescribed CellCept® 500 mg every 12 hours for at least 2 weeks before measuring the MPA area under the curve from 0 to 12 hours (AUC0-12). CellCept® was switched to Immucept® 500 mg every 12 hours for 2 weeks and MPA AUC0-12 was remeasured. RESULTS: Twenty patients with a median follow-up time of 35.4 (11.13-198.83) months were enrolled. Mean MPA AUC0-12 of Immucept® was higher than CellCept® without statistical significance (48.27 ± 2.31 µgâ hr/mL vs 42.19±15.20 µgâ hr/mL; P value = .59). No difference was revealed regarding the minimum measured concentration, maximum measured concentration, and time point with maximum concentration between both drugs. While on CellCept®, 5 patients (25%) had an MPA AUC0-12 < 30.0 µgâ hr/mL, but 3 patients (15%) had MPA AUC0-12 < 30.0 µgâ hr/mL when receiving Immucept®. However, 3 (15%) and 6 (30%) patients had MPA AUC0-12 > 60.0 µgâ hr./mL when treated with CellCept® and Immucept®, respectively. CONCLUSION: Generic MMF exhibited a comparable pharmacodynamic profile as the original formulation. MPA AUC0-12 was more than 30.0 µgâ hr/mL among most patients receiving MMF 1000 mg/day.

BACKGROUND: Renal histopathology is the best method available to assess chronicity ofglomerular diseases. However renal biopsy is an invasive procedure and is available only in medical schools or tertiary-care hospitals in Thailand. Clinical predictors that discriminate the chronicity index of renal pathology may be valuable for the best timing of biopsy. The authors conducted this study to identify the clinical parameters of severe fibrosis in glomerular diseases. MATERIAL AND METHOD: The authors retrospective analyzed all consecutive patients with glomerular diseases who underwent ultrasound-guided renal biopsy in Siriraj Hospital between 2008 and 2010. The patients were statified according to degree of tubulointerstitial fibrosis (IF) into mild to moderate group (IF < 50%) and severe group (IF ≥ 50%). Data of clinical and radiological parameters which relate to severe fibrosis were obtained. Formula for prediction of advanced IF was also developed by backward stepwise logistic regression analysis. The authors also validated the model by application to the patients who underwent kidney biopsy in our center between 2011 and 2012. RESULTS: Of a total 682 patients, 169 patients (24.8%) were classified as a severe IF group. In the multivariate model, higher serum creatinine, lower mean length of both kidneys and systolic blood pressure (SBP) of more than 140 mmHg were significantly related to severe IF All three factors were incorporated into apredictive model: e(x)/(1 +e(x)) while x = 1.3 + (0.6 x serum Cr in mg/dl)--(0.4 x mean length of both kidneys in cm)+(0.7 x 1 if SBP ≥ 140 mmHg or 0 if < 140 mmHg). The formula had AUROC of 0.82 and if calculated probability of fibrosis is higher than 0.37, it yields 90% specificity and 44% sensitivity for the prediction ofsevere fibrosis. When applied to 523 patients who underwent renal biopsy in 2011 and 2012, the sensitivity was 65.6% while specificity was 87.8%. CONCLUSION: High serum creatinine, presence of HT and decreased mean length of both kidneys are important clinical markers to predict renal fibrosis. The model constructed from these factors could be used in clinical practice for appropriate decision making.

Warfarin is the most prescribed oral anticoagulant. Adverse renal effect from warfarin therapy are uncommon and Thailand is not acquainted. Warfarin-related nephropathy (WRN) is a newly recognized complication of warfarin treatment, especially in patients with chronic kidney disease. The authors hereby report a 56-year-old man who developed gross hematuria and severe acute kidney injury (AKI) necessitating hemodialysis, following supra-therapeutic INR level. Renal pathology revealed extensive intratubular obstruction with red blood cell casts. From the literature, there were only twelve case reports of WRN, which were confirmed by renal histopatology. Renal survival of this condition was unsatisfactory. However, our patient was dialysis-independent after vitamin K treatment and temporary warfarin discontinuation. To the best of our knowledge, this is the first case report of biopsy-proven WRN in Thailand.

BACKGROUND: Lupus nephritis is an important leading cause of chronic kidney disease (CKD) among the young population in Thailand. Systemic lupus erythematosus (SLE) is often characterized by the presence of sympathetic hyperactivity, which results in a perishing outcome. Some physiological studies reveal that meditation may reduce this autonomic dysfunction. The authors hypothesized that meditation could be beneficial in alleviating the sympathetic hyperactivity and improving quality of life in lupus nephritis patients with CKD. MATERIAL AND METHOD: The authors performed a prospective pilot study, which enrolled lupus nephritis patients and categorized enrollees into meditation group and control group. Method of meditation was instructed by an expert in Buddhist studies for a duration of 60 minutes every month. Participants in the intervention group were advised to meditate every day for 24 weeks. To evaluate change in sympathetic activity, normetanephrine level was measured at beginning and the end of study and compared between both groups. Quality of life was determined by SF-36. Heart rate variability was also assessed in meditation group. RESULTS: Thirty eligible patients were recruited into the study. Fifteen patients were stratified in the meditation group and 15 patients in the control group. After meditation for 6 months, serum normetanephrine level decreased, but without statistical significance (0.105 vs. 0.059, p = 0.28). The reduction in normetanephrine level was also observed in the control group (p = 0.11). In the aspect of quality of life, scores of physical and mental components improved significantly. In meditation group, physical component score increased from 21.4 (5.0-50.2) to 62.2 (51.8-88.4) points (p < 0.01) and mental score increased from 16.9 (4.4-46.0) to 72.4 (45.1-81.6) points (p < 0.01). Quality of life score in the meditation group significantly increased more than in control group (p < 0.01). The parameter of heart rate variability in time and frequency domain also improved in the meditation group. CONCLUSION: In lupus nephritis patients with CKD, meditation shows a trend of benefits in reducing sympathetic overactivity and improving quality of life. Our results support the important role of meditation as a valuable adjunctive treatment of lupus nephritis with CKD.

BACKGROUND: Acute kidney injury (AKI) is frequently part of a multiple-organ dysfunction syndrome presenting in critically ill patients. Prolonged intermittent renal replacement therapy (PIRRT) provides the advantages of both continuous renal replacement therapy (CRRT) in term of hemodynamic stability and the cost-effectiveness of intermittent hemodialysis (IHD). This study aims to study PIRRT in the aspects of efficacy and hemodynamic outcomes. MATERIAL AND METHOD: The authors present a single-center experience accumulated over 20 months from February 2009 to September 2010 with two PIRRT techniques, called SLEDD and SLEDD-f. Eight-hour treatments were performed daily for three consecutive days. Hemodynamic parameters were recorded at different time points and blood samples were taken for urea and solute clearance before and after treatment. RESULTS: Sixty critically ill patients with AKI were randomly assigned to undergo PIRRT 33 patients received SLEDD and 27 patients received SLEDD-f. Our results demonstrate significant decrease in BUN, creatinine, serum potassium and phosphate in both PIRRT techniques. Moreover with the use of similar filters and blood flow rates, SLEDD-f was comparable with SLEDD in terms of small solute clearance and detoxification. For hemodynamic outcomes, the authors found that MAP increased after completion of the first session of PIRRT and along the three consecutive days of daily PIRRT, together with the gradual improvement of vasopressor scores. CONCLUSION: The prolonged intermittent renal replacement therapy (PIRRT) appears to be an outstanding technique for treatment of critically ill patients with AKI and it also seems to have cost effectiveness. Moreover it is suitable to a limited resource region such as Thailand.

Acute kidney injury is a rare but important complication of nephrotic syndrome. We demonstrated here nine patients with nephrotic syndrome and oliguric renal failure in Siriraj Hospital during 2007-2009. Renal biopsy was done in every patient. The results were focal and segmental glomerulosclerosis (FSGS) in three patients, minimal change disease in four patients and collapsing focal segmental glomerulosclerosis in two patients. Seven patients had dramatic response to corticosteroid treatment within a few weeks and had rapid recovery of renal function. The exact mechanism of idiopathic renal failure is not well understood but it might be related to reduction in ultrafiltration coefficient of the glomeruli.
