Clinical effect of Bailing capsule on patients after renal transplantation / 药学实践与服务

Objective To study the effect of Bailing capsule on renal function and other organ systems in 60 patients after renal transplantation in No. 910 Hospital of Joint Logistics Support Force. Methods 60 patients with renal allograft in 2018−2020 were divided into 2 groups according to different immunosuppressive regimens. In the control group, 35 cases were treated with MMF + CsA or FK506; in the treatment group, 25 cases were treated with MMF + CsA or FK506 + Bailing capsule. Blood and urine routine, liver and renal function and uric acid were measured after operation. The dosage of immunosuppressive drugs was recorded in stages at 48 weeks. Results The urinary red and white blood cell counts, blood aspartate transaminase and alanine transaminase, serum uric acid, total bilirubin and direct bilirubin in the treatment group were significantly less than those in the control group, while the serum total protein and albumin were significantly higher than those in the control group. The number of red blood cells and white blood cells in the treatment group was significantly higher than that in the control group at 12-48 weeks after kidney transplantation, and that in the lymphocyte group was significantly higher than that in the control group at 24-48 weeks after kidney transplantation. The dosage of CsA and FK506 in the treatment group was significantly lower than that in the control group after 48 weeks. Conclusion Bailing capsule could protect liver and kidney, stimulate hematopoiesis, improve hypoalbuminemia and reduce the dosage of immunosuppressant, which could be an ideal immunomodulator.

Analysis of factors associated with erectile dysfunction after renal transplantation / 现代泌尿外科杂志

【Objective】 To explore the factors influencing erectile dysfunction (ED) in male patients after renal transplantation, so as to provide basis for the prevention and treatment of this disease. 【Methods】 Kidney transplant recipients followed up in the Kidney Transplant Clinic of Xijing Hospital during Sep.1, 2022 and May 1, 2023 were selected as the study objects.Questionnaires were distributed, and the erectile function was measured with Sexual Health Inventory for Men (SHIM).Factors associated with ED were analyzed with multivariate logistic regression. 【Results】 A total of 300 questionnaires were distributed, and 276 valid ones were collected, including 182 cases (65.9%) suffering from ED of varying degrees.Multivariate logistic regression analysis showed that age [(50 years, OR: 0.120, 95%CI: 0.033-0.405, P50 years, OR: 0.223, 95%CI: 0.102-0.463, P40-50 years/>50 years, OR: 0.320, 95%CI: 0.139-0.719, P<0.01)], level of International Prostate Symptom Score (IPSS) (OR: 1.95, 95%CI: 1.211-3.248, P<0.01), International Prostate Symptom Score-Quality of Life item (IPSS-QoL) (OR: 1.482, 95%CI: 1.201-1.854, P<0.01), and income [(≥10 000 Yuan/<3 000 Yuan, OR: 0.156, 95%CI: 0.053-0.429, P<0.001), (5 000-<10 000 Yuan/<3 000 Yuan, OR: 0.418, 95%CI: 0.199-0.864, P<0.05), (≥10 000 Yuan/3 000-<5 000 Yuan, OR: 0.205, 95%CI: 0.069-0.573, P<0.01)] were independent and significant factors of ED. 【Conclusion】 The prevalence of ED in renal transplantation recipients is high.Age, income, IPSS and IPSS-QoL are the influencing factors.ED after renal transplantation is not only determined by physical and functional factors, but also closely related to social and psychological factors.

Efficacy of three plasma exchange methods in improving renal insufficiency after kidney transplantation and the induction of plasma exchange related adverse reactions: a comparative study / 中国输血杂志

【Objective】 To compare the efficacy of double filtration plasmapheresis(DFPP), centrifugal therapeutic plasma exchange(cTPE) and centrifugation-filtration plasmapheresis(CFPP) in improving renal insufficiency after kidney transplantation, as well as the differences in inducing plasma exchange-related adverse reactions. 【Methods】 Clinical data from 46 patients who underwent plasma exchange after renal transplantation in our hospital were retrospectively collected, and patiens were divided into DFPP group(n=33), cTPE group(n=7) and CFPP group(n=6). Changes in peripheral blood creatinine, albumin, hemoglobin, platelets, fibrinogen levels and urine volume before and after TPE were compared and analyzed among the three groups. 【Results】 Among the DFPP group, cTPE group and CFPP group, the creatinine after TPE decreased by (31.40±25.38)%, (58.91±19.75)% and (39.44±28.64)%, respectively, with cTPE group significantly higher than the DFPP group(P0.05); the urine volume after TPE increased by (49.33±30.03)%, (54.62±39.32)% and (68.89±23.00)%, showing no significant differences(P>0.05); the hemoglobin after TPE decreased by (11.97±5.94)%, (20.17±5.75)% and (9.65±8.75)%, respectively, with the cTPE group significantly higher than the DFPP group and CFPP group(P0.05). The platelet count after TPE decreased by (37.88±18.39)%, (24.56±12.36)% and (21.40±12.51)%, respectively, with no significant differences between the three groups(P>0.05); the fibrinogen after TPE decreased by (0.57±0.20)%, (0.14±0.06)% and (0.26±0.22)%, respectively, with the DFPP group significantly higher than the cTPE group(P0.05); the albumin after TPE decreased by (11.41±5.97)%, (14.67±6.52)% and (25.18±5.10)%, respectively, with cTPE group and DFPP group significantly lower than the CFPP group(P0.05). 【Conclusion】 The effect of three plasma exchange methods varies on renal function, anemia and coagulation function of patients after kidney transplantation. It is necessary to consider the the patient’s disease characteristics and treatment needs, as well as the laboratory′s technical conditions and plasma supply when selecting TPE methods.

Cases report and diagnosis and treatment of passenger lymphocyte syndrome after liver and renal transplantation / 中国输血杂志

【Objective】 To summarize the clinical features, serological features, blood transfusion protocols and treatment of 3 cases of passenger lymphocyte syndrome(PLS) after ABO-incompatibility liver and renal transplantation in our hospital, in order to provide guidance for comprehensive clinical understanding and recognition of this disease, especially early recognition and treatment. 【Methods】 By collecting the basic information of the patients and the time of cross-matching incompatibility of homologous blood after transplantation, observing the skin yellow staining, detecting hemoglobin value and other hemolysis indexes, and blood group serological detection results before and after transfusion, the diagnosis and analysis were performed. The diagnosis and treatment effect of PLS were analyzed by collecting the clinical outcome information after immunization and blood transfusion. 【Results】 Three cases of ABO-incompatible liver transplantation showed decreased hemoglobin and hemolysis, incompatible cross-matching of homologous blood, and anti-A and anti-B IgG antibodies were confirmed by serological test. After treatment such as immunosuppression and plasma exchange, blood transfusion was effective, hemolysis was improved, and antibodies gradually disappeared. 【Conclusion】 ABO blood group antibody screening, unexpected antibody screening and direct antiglobulin test(DAT)should be performed regularly for ABO-incompatible liver and renal transplantation cases, in order to detect the PLS early. A series of laboratory tests related to PLS should be performed in time to diagnose and adjust the treatment plan, including transfusion strategy, when homologous cross-matching is incompatible.

Comparison of palonosetron and ondansetron in preventing postoperative nausea and vomiting in renal transplantation recipients: a randomized clinical trial

Abstract Background: End-stage renal diseases patients have a high risk of postoperative nausea and vomiting (PONV), which is multifactorial and need acute attention after renal transplantation for a successful outcome in term of an uneventful postoperative period. The study was done to compare the efficacy of palonosetron and ondansetron in preventing early and late-onset PONV in live donor renal transplantation recipients (LDRT). Methods: The prospective randomized double-blinded study was done on 112 consecutive patients planned for live donor renal transplantation. Patients of both sexes in the age group of 18-60 years were randomly divided into two groups: Group O (Ondansetron) and Group P (Palonosetron) with 56 patients in each group by computer-generated randomization. The study drug was administered intravenously (IV) slowly over 30 seconds, one hour before extubation. Postoperatively, the patients were accessed for PONV at 6, 24, and 72 hours using the Visual Analogue Scale (VAS) nausea score and PONV intensity scale. Results: The incidence of PONV in the study was found to be 30.35%. There was significant difference in incidence of PONV between Group P and Group O at 6 hours (12.5% vs. 32.1%, p = 0.013) and 72 hours (1.8% vs. 33.9%, p < 0.001), but insignificant difference at 24 hours (1.8% vs. 10.7%, p = 0.113). VAS-nausea score was significantly lower in Group P as compared to Group O at a time point of 24 hours (45.54 ± 12.64 vs. 51.96 ± 14.70, p = 0.015) and 72 hours (39.11 ± 10.32 vs. 45.7 ± 15.12, p = 0.015). Conclusion: Palonosetron is clinically superior to ondansetron in preventing early and delayed onset postoperative nausea and vomiting in live-related renal transplant recipients.

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.

Clinical characteristics of 15 cases of renal transplantation with pre-exsiting donor-specific antibody / 中南大学学报(医学版)

Objective:Currently,patients with pre-exsiting donor-specific antibody(DSA)are prone to antibody-mediated rejection(AMR)after surgery and are at a relatively high risk of postoperative complications and graft failure.The risk of postoperative complications and graft failure is relatively high.This study aims to discuss the clinical outcome of DSA-positive kidney transplantation and analyze the role and safety of preoperative pretreatment in DSA-positive kidney transplantation,providing single-center treatment experience for DSA-positive kidney transplantation. Methods:We retrospectively analyzed the clinical data of 15 DSA-positive kidney transplants in the Department of Renal Transplantation of First Affiliated Hospital of Zhengzhou University from August 2017 to July 2022.Eight cases were organ donation after citizen's death(DCD)kidney transplant recipients,of which 3 cases in the early stage were not treated with preoperative desensitisation therapy(DCD untreated group,n=3),and 5 recipients were treated with preoperative rituximab desensitisation(DCD preprocessing group,n=5).The remaining 7 cases were living related donors recipients(LRD)who received preoperative desensitisation treatment with rituximab and plasma exchange(LRD preprocessing group,n=7).We observed and recorded the incidence of complications with changes in renal function and DSA levels in the recipients and the survival of the recipients and transplanted kidneys at 1,3 and 5 years,and to compare the differences in recovery and postoperative complications between 3 groups. Results:All 15 recipients were positive for preoperative panel reactive antibody(PRA)and DSA and were treated with methylprednisolone+rabbit anti-human thymocyte immunoglobulin induction before kidney transplantation.DCD untreated group all suffered from DSA level rebound,delayed renal graft function(DGF)and rejection reaction after surgery.After the combined treatment,DSA level was reduced and the graft renal function returned to normal.The DCD preprocessing group were all without antibody rebound,1 recipient developed DGF and the renal function returned to normal after plasmapheresis,and the remaining 4 recipients recovered their renal function to normal within 2 weeks after the operation.In the LRD preprocessing group,2 cases had antibody rebound and 1 case had rejection,but all of them recovered to normal after treatment,and DSA was maintained at a low level or even disappeared.The incidence of DGF and rejection in the DCD untreated group were significantly higher than that in the DCD preprocessing group and the LRD preprocessing group;and there were no significant difference in the incidence of postoperative haematuria,proteinuria,bacterial and fungal infections,and BK virus infection between the 3 groups(all P>0.05).A total of 11 of the 15 recipients were followed up for more than 1 year,6 for more than 3 years,and 1 for more than 5 years,and the survival rates of both the recipients and the transplanted kidneys were 100%. Conclusion:Effective preoperative pretreatment with desensitization therapy can effectively prevent antibody rebound in DSA-positive kidney transplantation and reduce perioperative complications.

Diagnostic value and analysis of two cases with Mucor infection after renal transplantation / 中国热带医学

@#Abstract: To report the diagnosis and treatment of Mucor infection in two cases of renal transplantation, and to provide reference for diagnosis and treatment of Mucor infection. Case 1, a male patient, who underwent allogeneic kidney transplantation due to increased creatinine for more than 8 years. The renal function had partially recovered 25 days after the operation, but then the patient suddenly got worse epigastric pain. Pathogen culture, smear microscopy, mass spectrometry identification and next-generation metagenomic sequencing (mNGS) were performed on the peritoneal drainage, with the result pointing to Rhizopus microsporus. The patient's condition improved after antifungal treatment using amphotericin B lipid complex (ABLC) and was discharged. Case 2, a male patient with hypertension and increased creatinine for more than 7 years was admitted to the hospital. After allograft kidney transplantation, tissue culture smear and histopathological examination suggested Mucor infection. The patient then underwent a "hand muscle debridement surgery + closed negative pressure drainage (VSD)" procedure, and amphotericin B was given postoperative treatment against Mucor infection and debridement. Subsequent retesting with mNGS showed no signs of Mucor infection. In the course of treatment, two patients developed abdominal pain after treatment with tegacycline, which was immediately diagnosed as pancreatitis and recovered after withdrawal. Both patients being male, with one case associated with hypertension. After initially guiding the diagnosis with traditional smear tests, final confirmation was done using histopathological examination, mNGS and mass spectrometry. One case was infected by Rhizopus microspora, and the other was infected by Rhizopus oryzae and Cunninghamia microbicans. The causes leading to Mucor infection in patients post renal transplantation varied greatly. Early diagnosis is the key to treatment of patients with Mucor infection after renal transplantation. Treatment with amphoteric B and its liposome is an effective means to improve mucormycosis patients after renal transplantation. The use of amphotericin B lipid complex treatment proved to be an effective treatment method for patients with Mucor infection after renal transplantation.

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.

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.

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 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.

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.

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.

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.

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.

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.
