[Living related liver transplantation in the Republic of Uzbekistan: current status and development prospects]. / Rodstvennaya transplantatsiya pecheni v Respublike Uzbekistan: nyneshnee sostoyanie i perspektivy razvitiya.

OBJECTIVE: To analyze primary results of living related liver transplantation in the Republic of Uzbekistan. MATERIAL AND METHODS: There were 44 living related transplantations of the right liver lobe in patients with decompensated liver failure between February 2018 and February 2023. RESULTS: Uneventful postoperative period was observed in 17 (38.6%) recipients. Other 27 patients (61.4%) developed 47 various postoperative complications (1-3 events per a patient). Of these, 8 (18.2%) patients required early postoperative re-laparotomy. Among 44 patients, 9 (20.5%) ones died in early postoperative period, and one patient died in long-term period (3 years after transplantation) from chronic rejection under refusal to take immunosuppressive drugs. Early satisfactory results were obtained in 79.5% of patients, long-term favorable outcomes - in 77.3% of cases. CONCLUSION: Engraftment rates and survival of recipients to a large extent depend on surgical strategy, baseline disease and clinical severity. The so-called "center effect" is essential at initial stages of implementation of the program.

Kidney transplantation from a living donor to a mentally disabled recipient with bilateral angiomyolipomas-A case report.

INTRODUCTION: Many centers do not perform transplantation in mentally disabled people. Our patient with progressive psychomotor developmental delay had bilateral angiomyolipomas. PRESENTATION OF THE CASE: Three years ago she underwent a right nephrectomy for massive spontaneous hemorrhage. The left kidney had a large, well-vascularized angiomyolipoma ready at any moment to bleed spontaneously was functioning normally. Two renal transplantation centers in Croatia refused to transplant from the patient's donor mother. The transplantation team had concerns whether to transplant a kidney to a person unable to care for herself, about who would take complete care of the patient, including regular immunosuppressive therapy, and whether it was ethically justified to explant a functioning kidney, although affected by angiomyolipomas, from a patient who required no renal replacement therapy at the time. CONCLUSION: We presented a successful kidney transplant in a mentally disabled person, clinical and ethical justifications for such a procedure, and a four-year post-transplant evaluation. Furthermore, in our opinion, renal transplantation in the mentally challenged needs to be referred to in literature exclusively as a relative contraindication instead of an absolute one, as has been practiced to date. This would facilitate transplantation teams deciding on kidney transplantation in mentally incapacitated individuals.

Pharmacokinetic analysis of tacrolimus in infants subject to living related liver transplantation and cardiac death liver transplantation / 中华器官移植杂志

Objective To analyze and compare the dosage,blood concentration and metabolic characteristics of Tacrolimus (Tac) for pediatric patients who underwent living related liver transplantation (LRLT) or donation after cardiac death liver transplantation (DDLT).Methods The clinical data of 75 liver transplantation pediatric patients from October 2012 to August 2015 were retrospectively analyzed.According to the different source of donors,the recipients were divided into two groups:LRLT group (40 cases) and DDLT group (35 cases).Results (1) Under the condition of same initial Tac dosage,the Tac dosage in LRLT group was less than in DDLT group during the first 28 days post-transplantation (P＞ 0.05).However,the Tac dosage in DDLT group was significantly higher than in LRLT group on the second and third months after sugery (P =0.000).(2) Correlation analysis revealed that graft-recipient body weight ratio (GRWR) was correlated with Tac dosage (mg·kg-1 ·d-1) on the 14th day postoperative (LRLT group:r=0.579,P＜0.05;DDLT group:r =0.583,P＜0.05) and Tac concentration/dosage ratio (LRLT group:r =-0.607,P＜0.05;DDLT group:r=-0.680,P＜0.05).Conclusion Tac has a satisfactory anti-rejection effect on liver transplantation pediatric patients while the metabolism varied with each individual.There is a positive correlation between the early Tac dosage and the GRWR in both groups.It is necessary to set individualized Tac administration regimen according to the metabolic characteristics and GRWR.

Analysis of marginal donor kidney in living donor kidney transplant / 中华泌尿外科杂志

Objective To analyze the clinical effectiveness of using marginal donor kidney in living kidney transplant. Methods From November 2005 to June 2011,274 cases of living kidney transplant were performed in the First Affiliated Hospital of Zhengzhou University.The cases were divided into the marginal donors group ( Donor ages over 60 years old,suboptimal renal anatomy or physiology) of 66 cases and standard donors group of 208 cases.The clinical data were retrospectively analyzed.The criteria of marginal donors were as follows:36 cases of donors with age over 60 yrs (6 cases with renal cysts and 1 case with renal calculus),22 cases of renal cysts ( with diameter range from 4 mm to 40 mm ),4 cases of renal calculus (with diameter range from 3 mm to 6 mm),4 cases of low GFR (under 35 ml/min.The mean recipients' serum creatinine before surgery and after surgery on day 3,day 7,month 1,month 3,month 6,month 12,related complications,the rate of acute rejection and delayed graft function,1 year,3 year recipient/kidney survival were compared between the 2 groups,respectively. Results The serum creatinine levels in the marginal donor group and standard donor group were (242.7 ± 132.2 vs 185.6 ± 148.4) and ( 156.7 ±86.8 vs 122.2 ± 136.8 ) on day 3,day 7 respectively ( P ＜ 0.05 ).Nevertheless,there were no significant differences between the 2 groups in recipients' serum creatinines before surgery and after surgery on month 1,month 3,month 6,month 12,peri-operative complications,the rate of acute rejection and delayed graft function,1 year,3 year recipient/kidney survival (P ＞ 0.05). Conclusions Healthy old donors and donors with renal cyst (the diameter of renal cysts under 40mm) should not be the barriers to organ donation.To those living donors with low GFR,we should consider of donor age,donor/recipient body weight,donor/recipient body surface area and whether we could deal with the problem by surgical operation.Donor with renal calculus should be carefully evaluated.

Influence of donating kidney of marginal donors on the early prognosis of recipients / 中华泌尿外科杂志

Objective To analyze the influence of donating kidney of marginal donors on the early prognosis of living-related kidney transplant recipients.Methods Sixty-six cases of living-re-lated kidney transplant patients between February 2004 and September 2007 were divided into the marginal donors group(28 cases)and non-marginal donors group(38 cases).Serum creatinine before and after surgery,creatinine clearance after surgery and perioperation complications were compared respectivelv between the 2 groups.Results The serum creatinine levels in the marginal donors group and non-marginal donors group were 154,131,127μmol/L and 132,117,118 ttmol/L on 7th day,1st month and 3rd month after transplantation respectively,and there were no significant differences between the 2 groups(P＞0.05).The serum creatinine level in parent-child donating kidney of the 2 groups Was 160,131,126μmol/L and 132,129,126μtmol/L on 7th day,1st month and 3rd month after transplantation respectively,and there were no significant differences too(P＞0.05).There was no difference in the rate of perioperation complications and creatinine clearance after kidney transplantation between the 2 groups.Conclusions The early prognosis of marginal donors'recipients is ideal.The marginal donors could be selected as the living-related kidney transplant donors,especially between parent and child,as long as they are evaluated according to stricter criteria.But the long-term prognosis of the recipients should be further observed.

Ethical Discussion on Living-related Donor Kidney Transplantation / 中国医学伦理学

It is an obvious contradiction between the shortage of kidney donors and the increasing demand for kidney transplantation.Living- related donor kidney transplantation may be a proper resolution,which has been academically proved to be superior to cadaveric kidney transplantation.However,there are still many ethical problems unsolved.Based on ethical theory and the"Seven Principles",we explore possible solutions to the ethical problems of living - related donor kidney transplantation.
