Argumentación ética en la donación de riñón de donante vivo y sano La autodeterminación, voluntad y generosidad superan los riesgos

el gesto altruista del donante vivo y sano de riñón, relacionado genética o sentimentalmente, se basa en autodeterminación, voluntad y generosidad. La argumentación ética alrededor de la donación de riñón de donante vivo y sano se orienta con las éticas principialista y personalista, la dignidad humana, la corporalidad, la divisibilidad del cuerpo, el mal menor y el mal mayor. Hace parte del derecho a la información amplia y suficiente que recibe el donante sobre los riesgos y posibles complicaciones físicas y morales del procedimiento, por medio del comité de bioética y el grupo de trasplantes. Con base en la argumentación ética planteada se procedió a contestar la pregunta de esta investigación: ¿se debe dejar que una persona viva y sana sea sometida a una cirugía que le dejará mononéfrico de por vida, solo por el deseo de ayudar a otro, a pesar de que existen programas activos con donante cadavérico? El objetivo de este artículo es plantear una argumentación ética sobre la donación de riñón de donante vivo y sano que contribuya a una adecuada orientación de su decisión.

the altruistic gesture of the healthy living kidney donor, genetically or sentimentally related, is based on self-determination, willingness, and generosity. The ethical argumentation around living and healthy kidney donation is guided by principled and personalistic ethics, human dignity, corporeality, divisibility of the body, the lesser evil, and the greater evil. It is part of the right to ample and sufficient information that the donor receives about the procedure's risks and possible physical and moral complications through the bioethics committee and the transplant group. Based on the ethical argumentation raised, we proceeded to answer the question of this research: should a living and healthy person be subjected to a surgery that will leave him/her mononephric for life, just because of the desire to help another, even though there are active programs with a cadaveric donor? This article aims to provide an ethical argumentation on living and healthy donor kidney donation that will contribute to an adequate orientation of their decision.

Hormonal intrauterine device in women with renal transplantation: a prospective observational study

SUMMARY OBJECTIVE: The main objective of this study is to evaluate the rate of continuity and satisfaction with hormonal intrauterine device in renal transplant recipients. METHODS: This was a prospective observational study. The sample consisted of patients treated at a Family Planning Outpatient Clinic, from August 2016 to September 2021. Information on each patient's age, parity, and associated diseases as well as satisfaction with the method were analyzed. Patients were invited to participate through electronic messages, and the questionnaire included questions about acceptance of the contraceptive method. RESULTS: A total of 40 patients were included in the study. The mean age of the renal transplant patients was 32.5 years. The mean duration of hormonal intrauterine device use was 37 months. Acceptance of the method was high, with 97.5% of patients remaining on the method for 1 year and 85% of patients using the hormonal intrauterine device at the time of the study. There were no pregnancies or renal transplant complications in the study. Regarding satisfaction with the method, the majority (77.5%) scored 10. CONCLUSION: Patients were satisfied or very satisfied with the hormonal intrauterine device. Therefore, the continuation rate was high. Furthermore, this contraceptive method proved to be safe and effective in kidney transplant recipients. No complications, graft rejection, or graft failure were observed after intrauterine hormonal device insertion and during follow-up.

Risk factors of urinary tract infection after renal transplantation / 现代泌尿外科杂志

【Objective】 To investigate the independent risk factors of urinary tract infection (UTI) in recipients under-going renal transplantation of donation after brain death (DBD), so as to provide a theoretical basis for the prevention and control of postoperative UTI. 【Methods】 A retrospective study was conducted for recipients who received renal transplantation of DBD in our hospital during Jan.2021 and Dec.2021. The recipients were divided into the infection group (n=26) and non-infection group (n=74) according to the incidence of UTI 3 months after operation. The risk factors of UTI were identified with univariate and multivariate analyses. 【Results】 The incidence of UTI was 26%. Univariate analysis showed that gender, postoperative urinary fistula, time of indwelling catheter and time of indwelling double J tube were the influencing factors of UTI (P<0.05). Forward stepwise regression analysis showed time of indwelling double J tube (OR=1.086,95%CI:1.003-1.177,P=0.042) and time of indwelling catheter(OR=4.687,95%CI:2.064-10.645, P<0.010) were the independent risk factors of UTI (P<0.05). 【Conclusion】 The time of indwelling catheter and time of indwelling double J tube are the independent factors of UTI after renal transplantation of DBD.

Estimation model for the exposure of mycophenolic acid in early renal transplant recipients / 中国药房

OBJECTIVE To establish the estimation model for the exposure of mycophenolic acid （MPA） in early renal transplant recipients [calculated by the area under the plasma concentration-time curve with 12 h （AUC0－12 h）]. METHODS Twenty kidney transplant recipients， who received triple immunosuppressive therapy of mycophenolate mofetil （MMF）+tacrolimus+ methylprednisolone， were selected and given MMF dispersible tablets （750 mg， q12 h） on the 15th day after the operation； the blood samples were collected from the patients before and 0.5， 1.0， 1.5， 2.0， 3.0， 4.0， 6.0， 8.0， 12.0 hours after the administration， respectively. The blood concentration of MPA was determined， and the pharmacokinetic parameters of MPA were calculated. The multivariate linear stepwise regression analysis method was used to fit an estimation formula for the finite sampling method suitable for MPA-AUC0－12 h of the recipients. Bland-Altman analysis was used to evaluate the agreement between the estimation formula and the classical pharmacokinetic method. RESULTS The main pharmacokinetic parameters of MPA in 20 renal transplant recipients： c0 was （1.53±0.84） μg/mL， cmax was （12.07±5.97） μg/mL， t1/2 was （5.41±3.67） h， tmax was （1.58±0.75） h， and the average AUC0－12 h calculated by the classical pharmacokinetic method was （33.95±13.40） μg·h/mL. MPA-AUC0－12 h was estimated with sampling points of “4.0， 8.0， 12.0 h”； the simplified calculation formula was AUC0－12 h＝12.058+2.819c4.0+7.045c8.0+ 3.879c12.0 （R 2＝0.934）. The predicted value had a good correlation and consistency with the measured value， and 95.0% of predicted values did not exceed the x±1.96SD （standard deviation） range. CONCLUSIONS The estimation model is established successfully for the exposure of MPA in early renal transplant recipients； the model has better prediction accuracy and fewer sampling points.

Supervivencia de pacientes trasplantados en relación con la compatibilidad inmunológica / Survival of transplant patients in relation to immunological compatibility

Introducción: El trasplante renal es uno de los métodos de sustitución de la función renal y tiene como factor de mayor influencia en su supervivencia, la compatibilidad inmunológica del sistema mayor. Objetivos: Definir la supervivencia del trasplante y su relación con el grado de compatibilidad. Métodos: Se realizó un estudio retrospectivo sobre el tiempo de supervivencia con base hospitalaria de los 512 trasplantes en el período comprendido entre los años 1993 y 2010, ambos incluidos con seguimiento y corte al concluir el año 2019. Se empleó el Kaplan Meier para calcular las supervivencias, se utilizó el paquete estadístico Statiscal Package Social Science (Spss) versión 22.0. Resultados: 397 pacientes recibieron riñones cadavéricos al momento del corte, 11,3 por ciento de los injertos estaban funcionando, mientras que para los 115 que recibieron de vivo, el 45,2 por ciento, p=0,000. La mediana de supervivencia para el cadavérico fue de 3,1 años (SD 2,4-3,8) y dentro de ellos los que compartieron tres o más antígenos lograron el doble de sobrevida, p=0,033. Para el de donante vivo, la mediana fue de 16,0 años (SD 9,1-22,9) y dentro de este grupo 104 pacientes que compartían un haplotipo lograron 44,2 por ciento de función, los hermanos que eran idénticos un 66,0 por ciento. Por parentesco los que recibieron riñones de hermanos tienen mejor supervivencias que de padres a hijos, p=0,001. Conclusiones: Se definió que la compatibilidad inmunológica del sistema mayor entre donante y receptor propicia diferencias en la función de los injertos(AU)

Introduction: Renal transplantation is one of the methods of renal function substitution and the main factor influencing survival is the immunological compatibility of the major system. Objectives: To define transplant survival and the relationship with the degree of compatibility. Methods: A retrospective study was carried out on the hospital-based survival time of 512 transplants from 1993 to 2010, including follow-up and the cut at the end of 2019. The Kaplan-Meier estimator was used to calculate the survivals, the statistical package Statistical Package Social Science (Spss) version 22.0 was used. Results: Three hundred ninety seven (397) patients received cadaveric kidneys at the cut, 11.3percent of the grafts were functioning, 115 received living grafts, 45.2percent p=0.000. The median survival for the cadaveric kidneys was 3.1 years (SD 2.4-3.8) and among them those who shared three or more antigens achieved twice the survival, p=0.033. For the living donor, the median was 16.0 years (SD 9.1-22.9) and within this group, 104 patients, sharing a haplotype, achieved 44.2percent function, siblings, who were identical, achieved 66 .0percent. By kinship, those who received kidneys from siblings have better survival than for those who received it from parents, p=0.001. Conclusions: Immunological compatibility of the major system between donor and recipient was defined to favor differences in the function of the grafts(AU)

Role of Ayurveda in the Prevention and Management of Nephrotoxicity

Nephrotoxicity, the prevalence and incidence of which is increasing day by day, is affecting very badly the quality of life of the sufferers in addition to the impalement of physical, mental, social and economical damages. The fact that the mortality rate of hospitalized patients with acute kidney injury over the last 40–50 years is almost constant and is not improving itself iterates its graveness. Treatment/management of acute kidney injury is primarily supportive, with the goals of preventing further damage and promoting recovery of renal function. It may include discontinuation, dose adjustment or monitoring of the medications prescribed. There are only few drugs like melatonin and lithium which are supposed to be having the potential of mitigation of drug-induced nephrotoxicity. If metabolic derangements from acute kidney injury do not respond to conservative treatment, either dialysis or renal replacement therapy is the only option to ensure the maintenance of homeostasis. But neither hemodialysis nor renal transplantation, which themselves bring about a lot of personal and familial difficulties, is free from side/adverse effects. Ayurveda, the ancient healing science, describes a lot of measures for the prevention and management of diseases in a great detail. Although nephrotoxicity seems to be a new entity, it can be very well prevented and managed with the adoption of Ayurveda in a cost effective and safe way. This article presents the nehroprotective effect of Ayurvedic advocacy and that of Ayurvedic plants evident by experiments in animal model.

Clinical characteristics of influenza A virus-induced pneumonia in renal transplantation recipients / 中华器官移植杂志

Objective:To explore the clinical characteristics, outcomes and influencing factors of influenza A virus-induced pneumonia in renal allograft recipients.Methods:During the 2015-2019 influenza season, 21 patients with influenza A virus-induced pneumonia after renal transplantation(RT)were prospectively recruited with 42 matched non-immunocompromised inpatients with influenza A virus-induced pneumonia.Clinical data, outcomes and follow-up observations after discharge were collected for analyzing the clinical characteristics of influenza A virus-induced pneumonia after RT.Continuous variables were compared by t-test or Mann-Whitney U test.And categorical variables were compared by Chi-Square test.Results:The median time after RT was 5(0.88, 10.50)years for RT recipients.In RT group, none received seasonal influenza vaccination with a vaccination rate of zero.The influenza vaccination rate of non-immunocompromised patients in current season was 42.86%(18/42)and inter-group difference was statistically significant( P<0.001). The levels of hemoglobin, aspartate aminotransferase, alanine aminotransferase and lactate dehydrogenase in RT recipients were(108.47±22.39)g/L, 21.00(16.00, 46.50)U/L, 15.00(12.00, 21.00)U/L and 314.00(207.25, 374.00)U/L.And the values were lower than those of non-immunocompromised patients[(130.24±21.74)g/L, 48.50(36.00, 79.50)U/L, 32.00(20.00, 52.25)U/L and 466.00(227.00, 781.75)U/L]. The differences were statistically significant( P=0.001, P<0.001, P<0.001, P=0.005). The levels of blood urea nitrogen and serum creatinine were 8.27(6.69, 12.48)mmol/L and 130.30(94.15, 204.70)mmol/L versus 5.42(3.37, 7.65)mmol/L and 65.90(48.98, 82.13)mmol/L in non-immunocompromised patients.The differences were statistically significant(all P< 0.001). No significant differences existed in the levels of C-reactive protein and procalcitonin between RT recipients and non-immunocompromised patients( P=0.774 and 0.821). The level of ESR and oxygenation index at admission were 39.00(13.00, 53.00)mm/h and(306.95±90.97)in renal recipients and 18.00(11.50, 23.00)mm/h and(200.17±116.35)in non-immunocompromised patients.The differences were statistically significant( P=0.045 and 0.001). Imaging studies indicated that multiple lobar involvement was a major imaging feature in both renal recipients and non-immunocompromised patients.The probability of pulmonary consolidation was 33.33%(7/21)in renal recipients and it was lower than that in non-immunocompromised patients.And the probability of pleural effusion was 42.86%(9/21)and it was higher than control.The inter-group differences were statistically significant( P=0.020 & 0.024). Rate of mechanical ventilation, CRRT and mortality were 42.86%(9/21), 23.81%(5/21)and 28.57%(6/21). All of them were higher than non-immunocompromised patients[21.43%(9/42), 9.52%(4/42)and 9.52%(4/42)]. However, there was no significant inter-group difference( P=0.076, 0.252 & 0.113). The median score of CURB-65 was 1(0.5, 1). Conclusions:Renal damage is prominent in hospitalized patients with influenza A virus-induced pneumonia after RT.There are a high rate of mechanical ventilation and CRRT during hospitalization and a high mortality.The prognosis remains poor for hospitalized patients with influenza A virus-induced pneumonia after RT.No matter how serious their conditions are at admission, they need to be closely monitored and aggressively treated.

Epidemiological analysis and prevention and control of human parvovirus B19 infection in 39 recipients of renal transplantation / 中华器官移植杂志

Objective:To explore the epidemiological characteristics, risk factors, preventions and treatments of recent human parvovirus B19 (HPV-B19) infections in recipients of renal transplantation (RT).Methods:From May 2020 to June 2021, retrospective review was conducted for epidemiological characteristics, treatment protocols, preventions and outcomes of HPV-B19 infected recipients after RT.Risk factors were analyzed using uninfected recipients after RT in the same period as controls.And 78 recipients who were not infected after RT with similar operation time were used as a control group for risk factor analysis.The infection rates of the four liver transplant recipients infected with HPV-B19 during the same period were calculated and compared with those of the kidney transplant recipients.Chi-square test and Fisher's exact test were used for statistical analysis.Results:During the observation period, HPV-B19 infection occurred in 39/368 recipients after RT with an overall infection rate of 10.60%(39/368). In terms of clinical symptoms, all 39 recipients presented with pure red cell aplasia (PRCA). In terms of season of infection, HPV-B19 infections occurred predominantly in autumn and winter [74.3% (29/39) of infections in autumn and winter, including 48.7% (19/39) in autumn]. Comparing the infection rates of different transplant recipients, 4 out of 123 liver transplant recipients were infected with HPV-B19 during the same period.The rate of infection was lower in liver transplant recipients than in RT counterparts (3.25% vs.10.60%, χ2=6.225, P=0.013). Analysis of OR values showed that transfusion of blood products was a risk factor for recent postoperative infection ( χ2=4.806, P=0.028, OR=2.418, 95% CI=1.088-5.373). Conclusions:HPV-B19 infection in renal transplant patients is mainly manifested as PRCA and is more likely than in liver transplant patients.Autumn and winter may be susceptible seasons for HPV-B19 and protection should be increased to prevent infection.Transfusion of blood products is a risk factor for recent HPV-B19 infection after RT, therefore donors should be routinely examined and it is imperative to test the safety of blood products in patients after RT.Thus HPV-B19 infection is well-controlled so that further spread may be prevented to avoid an epidemic outbreak.

The correlation between the prognosis of renal transplant recipients infected with BK virus and peripheral blood related indexes / 中华泌尿外科杂志

Objective:To investigate the correlation between the prognosis of patients infected with BK virus after renal transplantation and their peripheral blood related indexes.Methods:131 patients from the Renal Transplantation Department of the Second Xiangya Hospital of Central South University who underwent renal transplantation and firstly infected with BK virus after the surgery during the period from August 2018 to August 2021 were retrospectively analyzed. 93 males (71.0%) and 38 females (29.0%). The average age was (37.5±11.3) years old. 109 cases underwent cadaveric kidney transplant (83.2%) and 22 cases underwent relatives kidney transplant (16.8%). The onset time of the first infection with BK virus after renal transplantation was (188.7±16.6) days, and the serum creatinine was (127.5±39.5) μmol/L. 25 patients (19.1%)infected with BK virus were positive in blood and urine at the same time, and 106 patients (80.9%)infected with BK virus were positive only in urine. Among 131 patients infected with BK virus, 70 patients were treated by lowering the blood concentration of tacrolimus to enhance immunity, 12 patients were treated by switching tacrolimus to cyclosporine, and 49 patients had incomplete follow-up data. The DNA load of BK virus in 25 patients [5.6(2.4, 12.3)×10 3copies/ml] positive in blood, white blood cell count(WBC)(5.8±2.0)×10 9/L, hemoglobin(Hb)(122.0±22.4)g/L, platelet count(PLT)(187.1±63.1)×10 9/L, neutrophil count(NEUT)(3.9±1.7)×10 9/L, lymphocyte count(LYM)(1.5±0.8)×10 9/L, monocyte count(MONO)(0.4±0.2)×10 9/L, neutrophil to lymphocyte ratio(NLR)2.2(1.7, 3.5), derived neutrophil to lymphocyte ratio(dNLR)1.7(1.3, 2.6), platelet to lymphocyte ratio(PLR)121.3(86.3, 227.3), monocyte to lymphocyte ratio(MLR)0.2(0.1, 0.4) and lymphocyte to monocyte ratio(LMR)4.7±2.6. The DNA load of BK virus in 106 patients [20.4(0.4, 2 570.0)×10 5copies/ml] positive in urine, WBC 6.6(4.8, 9.1)×10 9/L, Hb(129.0±24.5)g/L, PLT 188.0(147.3, 226.5)×10 9/L, NEUT 4.6(3.0, 6.6)×10 9/L, LYM(1.7±0.8)×10 9/L, MONO 0.4(0.3, 0.5)×10 9/L, NLR 2.8(1.9, 3.9), dNLR 2.1(1.5, 3.0), PLR 120.5(87.0, 163.2), MLR 0.2(0.1, 0.4), LMR 4.5(2.8, 6.7). 70 patients infected with BK virus treated by lowering the blood concentration of tacrolimus were divided into BK virus rise group and BK virus decline group according to the change of BK virus DNA load in blood and urine before and after treatment (the grouping principle of this study gives priority to the change of BK virus DNA load in blood, followed by the change of BK virus DNA load in urine). The WBC, Hb, PLT, NEUT, LYM, MONO, NLR, dNLR, PLR, MLR, LMR, tacrolimus blood concentration and change difference, blood creatinine and change difference were analysed between two groups. Results:The BK virus DNA load in 25 patients positive in blood was correlated with NLR and dNLR ( r=0.5062, P=0.0098; r=0.5738, P=0.0027), and there was no correlation between the BK virus DNA load in blood with the WBC ( r=-0.0185, P=0.9302), Hb ( r=0.0912, P=0.6646), PLT ( r=-0.3931, P=0.0519), NEUT ( r=0.2438, P=0.2401), LYM ( r=-0.3035, P=0.1402), MONO ( r=-0.3279, P=0.1096), PLR( r=0.1054, P=0.6161), MLR( r=0.0738, P=0.7257), LMR( r=-0.0738, P=0.7257). There was no correlation between the BK virus DNA load in 106 patients positive in urine and WBC( r=0.0222, P=0.8209), Hb( r=-0.0323, P=0.7423), PLT( r=0.0847, P=0.3881), NEUT( r=0.0417, P=0.6713), LYM( r=0.0010, P=0.9916), MONO( r=0.0224, P=0.8196, NLR( r=0.0170, P=0.8623), dNLR ( r=-0.0013, P=0.9892), PLR( r=0.0387, P=0.6934), MLR( r=-0.0070, P=0.9433)and LMR( r=0.0070, P=0.9433). As for 70 patients infected with BK virus, there were 37 patients in the BK virus rise group and 33 patients in the BK virus decline group. In the two groups, age [(38.4±12.0)years old and(39.0±9.0)years old], gender [male /female: (23/14) cases and(27/6)cases], blood type [A+ /B+ /AB+ : (22/13/20)cases and (26/6/1)cases], donation type [relatives donnation/cadaveric donation: (29/8)cases and (27/60)cases], blood creatinine(after treatment)[123.0(98.4, 140.5)μmol/L and 132.0(107.1, 162.4)μmol/L] and change difference before and after treatment [0(-15.7, 10.5)μmol/L and -2.0(-9.1, 15.0)μmol/L], tacrolimus blood concentration (after treatment)[(6.7±2.0)ng/ml and(6.5±1.5)ng /ml] and tacrolimus concentration change difference [-1.4(-3.8, 0.6)ng/ml and -1.2(-2.2, 1.3)ng/ml] had no significant difference( P<0.05). The MONO of the two groups was statistically different [0.3(0.2, 0.5)×10 9/L and 0.4(0.3, 0.6)×10 9/L, P=0.033], and there was no difference between the two groups in WBC[6.6(4.1, 8.8)×10 9/L and 6.8(5.4, 8.9)×10 9/L], Hb[(133.2±25.3)g/L and(131.6±20.6)g/L], PLT[185.0(151.0, 231.5)×10 9/L and 196.0(149.0, 234.0)×10 9/L], NEUT[4.3(2.4, 6.4)× 10 9/L and 4.2(3.1, 5.5)×10 9/L], LYM[1.7(1.1, 2.2)×10 9/L and 1.8(1.1, 2.3)×10 9/L], NLR[2.5(1.9, 3.8)and 2.4(1.9, 3.7)], dNLR [2.0(1.5, 2.8)and 1.9(1.4, 2.5)], PLR [114.9(85.1, 159.4)and 111.3(77.1, 159.6)], LMR(4.6±2.6 and 5.2±2.4), MLR[0.2(0.2, 0.4)and 0.2(0.2, 0.4)]( P<0.05).

The rise of MONO correlates with good prognosis of BK virus.

Clinical features and treatment of calcineurin inhibitor-induced pain syndrome in renal transplant recipients / 药学实践杂志

Objective To understand the clinical features and therapeutic methods for calcineurin inhibitor-induced pain syndrome (CIPS) in kidney transplant recipients. Methods The related articles or abstracts from January 1991 to December 2020 were obtained by searching PubMed, Google Scholar, CNKI, Wanfang and VIP databases. The reviews, duplicate literatures and the articles involved in non-kidney transplant recipients were excluded. 11 full papers were included with 15 case reports. Results The average age of patients at the time of diagnosis of CIPS was (44.6±8.31) years, and the 53.3% of the patients was male. The average appearance time of CIPS was (2.42±3.07) months after kidney transplantation. CIPS mainly affected bilateral hands, elbows, wrists, knees, ankles, feet and back. The patients had normal or elevated trough concentrations of calcineurin inhibitors (CNIs) when CIPS occurred. Some patients had elevated alkaline phosphatase, parathyroid hormone, blood calcium, C-reactive protein levels, and abnormal phosphorus levels, while rheumatoid factor and uric acid levels were normal. CIPS symptoms in most patients disappeared with dose reduction of CNIs, change to different class of CNIs, pamidronate IV injection, pregabalin, calcium channel antagonists, etc. The average recovery time was (4.43±3.31) months. Conclusion The most effective treatment for CIPS is to reduce the dose of CNIs and replace immunosuppressants. Other treatments include GABA analogs, intravenous pamidronate, calcium channel blockers and conservative therapy.

Comparison of tube method versus gel method for the results of blood group IgM antibody titration in ABO-incompatible kidney transplant recipients / 中华器官移植杂志

Objective:To explore the critical value of different blood group antibody titration in ABO blood group incompatible kidney transplant(ABOi-KT)recipients by tube and gel methods to provide rationales for selecting the threshold value of antibody titration before ABOi-KT.Methods:From January 2019 to April 2021, 681 blood group antibody titrations were performed for 214 ABOi-KT recipients.There were type A( n=135), type B( n=168)and type O( n=378). The difference, correlation and consistency of two methods were statistically analyzed. Results:Tube method was 2 gradients lower than gel method(4-fold dilution)and the results were significantly different( P<0.000 1). Spearman's test indicated that the results of two methods were significantly correlated( P<0.000 1). The results of intraclass correlation coefficient showed that the consistency of two methods was general for type A recipients(ICC=0.640), decent for type B recipients(ICC=0.751)and poor for type O recipients(ICC<0.4). When the critical value of tube method was set, titration of type A anti-B was 16, titration of type B anti-A 8 and titration of type O anti-A/B 8.And the corresponding critical values of gel was type A anti-B 32, type B anti-A 16 and type O anti-A/B 16. Conclusions:The results of ABO blood group IgM antibody titration by gel and tube methods are correlative.And gel method is recommended for more stable and reproducible results.

Experience in the treatment of heart kidney transplantation through non-staged transplant: a report of 11 cases / 中华器官移植杂志

Objective:To explore the treatments and outcomes of heart and kidney transplantation(HKTx)and summarize its management experiences.Methods:From October 2016 to October 2020, clinical data, treatment strategies and prognosis of 11 patients received HKTx were analyzed retrospectively.In 11HKTx cases, the ratio of male-to-female was 10∶1, the age(50.6±12.9)years and the preoperative body mass index(26.72±3.29)kg/m 2.The preoperative cardiac function was class Ⅳ and the preoperative left ventricular ejection fraction(29.40±4.48)%.All patients were in uremic state pre-operation and underwent regular dialysis.The mean duration of dialysis was 2.5(0.5-7.0)years, preoperative creatinine 753.5(434-1144)μmol/L and preoperative predictive glomerular filtration rate 5.59(3.93-17.23)ml/(min preop 2). Non-staged transplant was performed and donor heart and kidney were from the same donor.The median time of cold cardiac ischemia 2.75(2.5, 4.0)hours, the median time of cold renal ischemia 9(8.5, 15.0)hours and the median time from the end of heart transplantation to the beginning of kidney transplantation 2(1.0, 3.5)hours.The immunosuppressive regimen was a combination of tacrolimus, mycophenolate mofetil and methylprednisolone. Results:Normal cardiac function and renal function normalized in 9 cases.At Month 6 post-operation, the postoperative left ventricular ejection fraction was(57.55±2.51)%, creatinine 107.7(85-132)μmol/L and urine volume in 24h 1988(1800-2200)ml.The long-term survival time was 6-62 months.No such complications as infection or rejection occurred in 9 patients.The cardiac function was class Ⅰ at Month 6 post-operation.One patient died from pulmonary mucor infection at Month 4 post-operation.Another death was due to gastrointestinal fungal infection at Month 1 after HKTx.Conclusions:HKTx is an effective treatment for end-stage heart disease with renal failure.

Artery stenosis in renal grafts from infantile donors to adult recipients / 中华器官移植杂志

Objective:To explore the clinical characteristics, causes, diagnosis and treatment of transplant renal artery stenosis after pediatric-to-adult kidney transplantation.Methods:Between July 2014 and March 2019, clinical data were retrospectively reviewed for 25 en-bloc and 27 single kidney transplant cases.Results:One en-bloc(4.0%)and two single kidney recipients(7.4%)were diagnosed as renal artery stenosis at Month 13-23 months post-transplantation.It was higher than the rate of stenosis in adult-to-adult transplant cases(1.1%)during the same period.As compared with recipients without stenosis, stenotic ones had younger pediatric donors( P<0.05)and yet similar body weight of donors as well as recipients( P>0.05). The inner diameters of stenonotic sites were(1.40-1.63)mm and predominant stenotic site was proximal renal artery rather than anastomotic site.The remaining parts of major renal arteries varied from 2.31 to 4.93 mm in diameter.It was normal in children with a corresponding age.All three cases responded well to percutaneous transluminal angioplasty and stenting. Conclusions:The cause of stenosis may be an undeveloped local artery diameter due to extensive tissue dissection around artery.Therefore cautious selections of infantile single renal graft for adult recipients and preserving surrounding tissue of renal artery assist in the prevention of graft arterial stenosis.

Influence of prophylactic resection of orthotopic polycystic kidney disease on perioperative complications and surgical difficulty of renal transplantation in patients with ADPKD / 国际外科学杂志

Objective:To explore whether prophylactic resection of orthotopic polycystic kidney before allogeneic kidney transplantation can reduce the incidence and severity of perioperative complications in patients with end-stage renal disease due to autosomal dominant polycystic kidney disease (ADPKD), and reduce the difficulty of surgery.Methods:A retrospective case-control study method was used to recruit a total of 27 patients who were diagnosed with ADPKD and underwent allogeneic kidney transplantation in Beijing Friendship Hospital, Capital Medical University from January 2013 to January 2021, they were divided into prophylactic resection group ( n=19) and non-prophylactic resection group ( n=8) according to whether orthotopic polycystic kidney disease was prophylactic resection before transplantation. Patients in prophylactic resection group underwent orthotopic polycystic kidney resection before transplantation, while patients in non-prophylactic resection group didn′t. The indexes such as hemoglobin, platelet, albumin, left ventricular wall thickness, left ventricular ejection fraction, difficulty of kidney transplantation, average postoperative hospital stay, pain, and complication rate before kidney transplantation were analyzed and compared between the two groups. Measurement data were expressed as mean ± standard deviation ( ± s), and independent sample t-test was used for comparison between groups; Chi-square test was used for comparison of enumeration data between groups. Results:There was no significant difference in the general status of hemoglobin, platelets, albumin, left ventricular wall thickness, and left ventricular ejection fraction between the two groups before kidney transplantation ( P>0.05). However, the polycystic kidney volume [(2 409.8±1 899.8) cm 3] in the prophylactic resection group was greater than that in the non-prophylactic resection group [(1 340.2±290.6) cm 3], and the difference was statistically significant ( P=0.027). In terms of postoperative complications, 9 patients in the prophylactic resection group and 5 patients in the non-prophylactic resection group developed long-term low back pain or hematuria after transplantation, which were considered to be related to the unresected polycystic kidney disease, but the difference was not statistically significant ( P=0.678). Meanwhile, in both two groups, 3 patients underwent orthotopic polycystic nephrectomy after transplantation due to severe polycystic kidney complications. Although the incidence of complications in the prophylactic resection group (15.8%) was lower than that in the non-prophylactic resection group (37.5%), the difference was not statistically significant ( P=0.319). Conclusion:Prophylactic resection of orthotopic polycystic kidney before kidney transplantation can reduce the incidence and severity of polycystic kidney-related complications after transplantation, but has little effect on the operation time and intraoperative blood loss of kidney transplantation.

Characteristic of medication compliance behavior in renal transplantation patients / 中南大学学报(医学版)

OBJECTIVES@#After renal transplantation, patients need to take various immunosuppressant, but the drug compliance is poor. The theory of planned behavior suggests that the past medication behavior and subjective norms of individuals are closely related to medication compliance. This study aims to explore the change of medication compliance behavior and its influenting factors for renal transplantation patients at different stages.@*METHODS@#This study was a prospective longitudinal study. The Basel Assessment of Adherence with Immunosuppressive Medication Scale (BAASIS), Medication Belief Scale, Social Support Scale and Quality of Life Scale were used to dynamically follow up renal transplantation patients at pre-operation and 1-month, 6-month, and 12-month after transplantation.@*RESULTS@#A total of 300 patients completed the whole follow-up. The percentage of patients with good medication compliance was 97.60%, 87.30% and 84.30% at 1-month, 6-month and 12-month after transplantation respectively. The life quality of the patients was decreased at 6 months after the operation, and the patients with better self-reported life quality had poor medication compliance. After adjusting for demographic data, the risk of medication incompliance in patients with poor medication compliance before operation was 37.646 times than those with good compliance. Patients who did not use medication reminders had high risk (odds ratio=2.467) of drug non-adherence. The risk of drug non-adherence in patients with more postoperative misgivings was 1.265 times compared with that in patients with less postoperative misgivings.@*CONCLUSIONS@#The medication compliance decreases with the time of transplantation, but the medication compliance of patients with good self-reported life quality is poor. Medication concerns reduce the compliance behavior. Preoperative medication behavior has a significant predictive effect on postoperative behavior. Medication reminder is a protective factor for promoting compliance. Medical staff should pay more attention to preoperative medication belief, behaviors and reminder of using drug so as to provide precise intervention in the renal transplantation patients.

Application of plasma with same blood group as kidney donor to preconditioning of ABO incompatible kidney transplantation / 中华器官移植杂志

Objective:To explore the feasibility of applying plasma with same blood group as kidney donor to ABO incompatible kidney transplantation(ABOi-KT)preconditioning of blood group O recipients with high-titer anti-A/B preformed antibody(IgM/IgG titer ≥1∶256).Methods:A total of 15 cases of blood group O ABOi-KT recipients with high-titer anti-A/B were recruited and divided into two groups of AB( n=8)and kidney donor's blood(KD, n=7)according to plasma type for plasma exchange during preconditioning phase. Clinical data of preconditioning and post-KT were recorded. Results:They received plasmapheresis(PP)(8.1±2.5)sessions in preconditioning phase, including double plasma filtration(DFPP)(4.0±1.4)sessions and plasma exchange(PE)(4.1±2.0)sessions, PP frequency was(0.8±0.1)sessions per day. No hemolysis reaction occurred during preconditioning phase. Anti-A/B titers declined as expected and fulfilled the ABOi-KT criteria(IgM/IgG titers ≤1∶8). KT was performed successfully without antibody-mediated rejection. All of them survived with normal renal function within 90 days post-KT. Levels of serum creatinine at Day 7/30/90 post-KT were(92.9±30.4), (96.2±25.9)and(103.1±28.4)μmol/L; anti-A/B IgM titers at Day 7/30/90 post-KT 1∶1-1∶32, 1∶1-1∶64 and 1∶1-1∶32; anti-A/B IgG titers at Day 7/30/90 post-KT 1∶1-1∶64, 1∶1-1∶64 and 1∶1-1∶32 respectively. No significant differences existed in count/frequency of PP sessions, levels of serum creatinine or anti-A/B titers at each observation point between AB and KD groups( P>0.05). Conclusions:Plasma with the same blood group as kidney donor is feasible for maximizing the intensity of ABOi-KT preconditioning. Favorable outcomes may be achieved through an intensified desensitization strategy on blood group O recipients with high-titer anti-A/B preformed antibody. The potential risks and long-term outcomes should be further explored.

Evaluation of renal transplantation recipients those who do not use steroid with panel reactive antibody and donor specific antibody / Evaluación de receptores de trasplante renal que no usan esteroides con panel de anticuerpos reactivos y anticuerpos específicos del donante

ABSTRACT Background: Steroids are the mainstream drugs of immu- nosuppressive regimen in renal transplantation. They are successfully used on induction, maintenance and rejection treatment. Due to complications caused by steroids, treatments are switched to immunosuppressive agents. Graft dysfunction risk caused by reduced total immunosuppression disturbs clinicians very often. We documented the differences among patients by means of clinical presentation and PRA/DSA levels between patients who are using steroids and patients that were prescribed for steroid-free regimen. Methods: 82 individuals who did not use steroid and 52 patients on steroid treatment were included with similar rates of age, sex, primary renal disease, dialysis type, posttransplant follow-up duration and donor type. Pre and posttransplant PRA, DSA levels, posttransplant and current graft function and comorbidities were evaluated. Results: Individuals who do not use steroids were found to have a lower posttransplant creatinine level and glomerular filtration rate (GFR) compared to steroid users. Posttransplant and current spot urinary protein/creatinine rates were also lower in the steroid-free group. However DM, BKVN and induction therapy rates were higher in the steroid-free group. PRA and DSA levels were similar in both groups. On the other hand, posttransplant PRA-I levels were significantly higher in those with less steroid use time. Conclusions: Although steroid free regimens usually worry the clinicians, they can be preferred in patients with low immunological risk for rejection to avoid its side effects such as uncontrolled diabetes, obesity, musculoskeletal problems and cataracts.

RESUMEN Antecedentes: Los esteroides son los principales fármacos del régimen inmunosupresor en el trasplante renal. Se utilizan con éxito en tratamientos de inducción, mantenimiento y rechazo. Debido a las complicaciones causadas por los esteroides, los tratamientos se cambian a agentes inmunosupresores. El riesgo de disfunción del injerto causado por la reducción de la inmunosupresión total perturba a los médicos con mucha frecuencia. Documentamos la diferencia entre los pacientes por medio de la presentación clínica y los niveles de PRA/DSA en aquellos que utilizan esteroides y a los que se les prescribió un regimen sin esteroides. Material y métodos: Se incluyeron 82 individuos que no usaban esteroides y 52 pacientes en tratamiento con esteroides con tasas similares de edad, sexo, enfermedad renal primaria, tipo de diálisis, duración del seguimiento postrasplante y tipo de donante. Se evaluaron la ARP pre y postrasplante, los niveles de DSA, la función y comorbilidades postrasplante y actual del injerto. Resultados: Se encontró que las personas que no usan esteroides tienen un nivel de creatinina postrasplante y una tasa de filtración glomerular (TFG) más bajas en comparación con los usuarios de esteroides. Las tasas de proteína/creatinina urinarias postrasplante y puntuales actuales también fueron más bajas en el grupo sin esteroides. Sin embargo, las tasas de DM, BKVN y terapia de inducción fueron más altas en el grupo sin esteroides. Los niveles de PRA y DSA fueron similares en ambos grupos. Por otro lado, los niveles de PRA-I postrasplante fueron significativamente más altos en aquellos con menos tiempo de uso de esteroides. Conclusiones: Aunque los regimenes libres de esteroides suelen preocupar a los clínicos, pueden ser preferidos en pacientes con bajo riesgo inmunológico de rechazo para evitar sus efectos secundarios, como diabetes no controlada, obesidad, problemas musculoesqueléticos y cataratas.

Resumen Objetivo: Establecer las posibles implicaciones clínicas y quirúrgicas asociadas a la presencia de arterias renales accesorias y su relación con desenlaces relevantes para la salud como la hipertensión arterial sistémica resistente y el rechazo agudo de trasplantes renales. Material y métodos: Revisión sistemática de la literatura registrada en International Prospective Register of Systematic Reviews. Cuatro autores cegados realizaron su búsqueda de 2008 a 2018, según criterios de inclusión, términos y combinaciones prestablecidos, en cinco bases de datos y gestor de referencias bibliográficas Zotero, evaluación de calidad con la herramienta Study Quality Assessment Tools, del National Heart, Lung, and Blood Institute y cálculo de índice Kappa. Resultados: 32 estudios seleccionados, superaron el mínimo de puntuación en la evaluación de la calidad metodológica, revelando bajo riesgo de sesgo. El grado de acuerdo entre los revisores, fue de 0.81-1.0, interpretado como concordancia, casi perfecta. Las características de los estudios, según el año de publicación fue considerable para los años 2013 y 2009. La mayoría de los estudios fueron realizados en Estados Unidos, seguido de otros países. Como desenlaces se encontraron seis estudios para Hipertensión arterial sistémica y 26 para Trasplante renal. Conclusiones: La presencia de arterias renales accesorias es una de las posibles causas a valorar en pacientes hipertensos con refractariedad al tratamiento convencional. Por su parte, la incidencia de rechazo y pérdida de viabilidad post trasplante renal se aproxima al 20% en pacientes con arterias renales accesorias y se asocia con complicaciones urológicas o sistémicas.

Abstract Objective: To establish some of the possible surgical and clinical implications related to the presence of accessory renal arteries and their relationship with relevant health outcomes like resistant systemic hypertension and acute rejection of renal transplantation. Methods: Systematic review of the literature registered in the International prospective register of systematic reviews. Four blinded authors carried out their search from 2008 to 2018, according to the inclusion criteria, pre-established terms, and combinations, in five databases and the Zotero bibliographic reference manager, quality assessment with the Study Quality Assessment Tools, from the National Heart, Lung, and Blood Institute, and calculation of Kappa indices. Results: 32 selected studies exceeded the minimum score in the assessment of methodological quality, revealing a low risk of bias. The degree of agreement between the reviewers was 0.81-1.0, interpreted as almost perfect concordance. The characteristics of the studies, according to the year of publication, were considerable for the years 2013 and 2009. Most of the studies were carried out in the United States, followed by other countries. Based on the outcomes, the following studies were found, six for systemic arterial hypertension and 26 for kidney transplantation. Conclusions: The presence of accessory renal arteries is one of the possible causes when assessing hypertension patients with refractoriness to conventional treatment. For its part, incidence of acute rejection and post-transplantation loss of viability are near 20% in patients treated with accessory renal arteries; it is associated with urological and systemic complications.

Effect of learning curve on the perioperative course of robotic-assisted laparoscopic donor nephrectomy compared with laparoscopic donor nephrectomy

Summary OBJECTIVE: This study was designed to compare the standard and robotic-assisted laparoscopic donor nephrectomy in terms of perioperative course, short-term postoperative outcome, and to evaluate the effect of surgeon's learning curve on these parameters. METHODS: This was a prospective randomized study including 60 patients (mean age, 47 years; age, 21-72 years; 26 males, 34 females) who had been planned laparoscopic donor nephrectomies in our clinic. For comparison of standard and robot-assisted techniques and to evaluate the impact of learning curve, patients were randomized into three groups by a computer, each group containing 20 patients. Group 1: standard laparoscopic donor nephrectomies; Group 2: the first 20 patients who underwent robot-assisted laparoscopic donor nephrectomy; and Group 3: the next 20 patients who underwent robot-assisted laparoscopic donor nephrectomy. RESULTS: Operative time was significantly higher in Group 2 (221.0±45.1 min) than both Group 1 (183.5±16.9 min, p=0.001) and Group 3 (186.5±20.6 min, p=0.002). Similarly, time for laparoscopic system setup was significantly higher in Group 2 (39.5±8.6 min), which contained the first cases of robot-assisted laparoscopic donor nephrectomy where surgeon had least experience than Group 1 (19.3±3.7 min, p<0.001) and Group 3 (24.0±9.4 min, p<0.001). On the other hand, duration of operation and time for laparoscopic system setup was similar between Groups 1 and 3. CONCLUSIONS: Learning curve extends the operative time and laparoscopic system setup time in robotic-assisted laparoscopic donor nephrectomy, however, after the learning process was completed, these parameters were similar between robotic-assisted and standard laparoscopic nephrectomy.
