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.

Regulation mechanism of macrophage transition in renal fibrosis / 器官移植

Renal fibrosis is a common pathological change from development to end-stage renal diseases in all progressive chronic kidney diseases. Renal fibrosis after kidney transplantation will severely affect the renal graft function. Macrophages are characterized with high heterogeneity and plasticity. During the process of kidney injury, macrophages are recruited, activated and polarized by local microenvironment, and participate in the process of renal tissue injury, repair and fibrosis through multiple mechanisms. Recent studies have shown that macrophages may transit into myofibroblasts and directly participate in the formation of renal fibrosis. This process is known as macrophage-myofibroblast transition. Nevertheless, the regulatory mechanism remains elusive. In this article, the role of macrophages in renal fibrosis, the characteristics of macrophage-myofibroblast transition and the possible regulatory mechanism were reviewed, aiming to provide reference for relevant research of renal fibrosis.

Research report of living donor kidney harvesting in Bama miniature pigs with six gene modified / 器官移植

Objective To summarize the experience and practical value of living donor kidney harvesting in Bama miniature pigs with six gene modified. Methods The left kidney of Bama miniature pigs with six gene modified was obtained by living donor kidney harvesting technique. First, the ureter was occluded, and then the inferior vena cava and abdominal aorta were freed. During the harvesting process, the ureter, renal vein and renal artery were exposed and freed in sequence. The vascular forceps were used at the abdominal aorta and inferior vena cava, and the renal artery and vein were immediately perfused with 4℃ renal preservation solution, and stored in ice normal saline for subsequent transplantation. Simultaneously, the donor abdominal aorta and inferior vena cava gap were sutured. The operation time, blood loss, warm and cold ischemia time, postoperative complications and the survival of donors and recipients were recorded. Results The left kidney of the genetically modified pig was successfully harvested. Intraoperative bleeding was 5 mL, warm ischemia time was 45 s, and cold ischemia time was 2.5 h. Neither donor nor recipient pig received blood transfusion, and urinary function of the kidney transplanted into the recipient was recovered. The donor survived for more than 8 months after the left kidney was resected. Conclusions Living donor kidney harvesting is safe and reliable in genetically modified pigs. Branch blood vessels could be processed during kidney harvesting, which shortens the process of kidney repair and the time of cold ischemia. Living donor kidney harvesting contributes to subsequent survival of donors and other scientific researches.

Heavy chain deposition disease in a case of clear cell renal cell carcinoma- A jack in the box

Renal cell carcinoma (RCC) is the most common subtype of adult renal tumors, and its detection rate in the early stages has been increased in the dawn of advanced imaging modalities. Nephrectomy is the mainstay of treatment; determination of tumor category and staging is the primary concern of oncopathologists. Non-neoplastic renal parenchyma is overlooked majority of times and thus misses the opportunity to detect concomitant medical renal diseases which also predict the renal outcome in the postoperative era. Although any kind of glomerular or extraglomerular pathology may be encountered, vascular changes in the form of arterionephrosclerosis are the commonest one. Here, we take the opportunity to report an unusual association of heavy chain deposition disease (HCDD) with clear cell subtypes of renal cell carcinoma in a 48-year-old male of Indian ethnicity.

Health equity in dialysis care: Time for action

The development of chronic kidney disease and its progression to End Stage Renal Disease requiring renal replacement therapy remains a significant source of reduced quality of life and premature mortality. The global dialysis population and treatment gap is growing, especially in low- and middle- income countries. In India, 70% of those starting dialysis, die or discontinue treatment in the initial period due to the high cost of treatment and lack of access to dialysis therapy. Achieving health equity requires ensuring access to the resources that needs to be healthy, and addressing social determinants of health involves needs factors that influence the health outcomes. Universal Health Coverage requires an alternate model to address the substantial Out-Of-Pocket-Expenditure borne by these patients for traveling and medications.

Financial toxicity and dialysis: Autonomy and truth-telling in resource-limited settings

From an ethical perspective, resource limitations provide a challenge for healthcare providers. Handling disclosure of the financial details of treatment options in a way that empowers patients, even in the face of extreme poverty, requires careful consideration of the personal preferences and motivations of each patient. This article will consider the high costs of dialysis for patients experiencing extreme poverty in light of various ethical principles, including informed consent and truth-telling. It will conclude that a graduated method of disclosing the physical and financial burdens of each treatment option is the best way forward, particularly for healthcare workers engaged in resource-limited settings.

Etiology of Chronic Kidney Disease in Nigeria and Management Challenges

The prevalence of chronic kidney disease (CKD) is increasing globally and is one of the noncommunicable diseases associated with increase mortality globally in the last two decades. The prevalence of CKD in Nigeria, it is 1.6% to 12.4%. Ninety percent of end-stage renal disease (ESRD) patients are said to die within 3 months of commencing dialysis. Indices are even worse in resource poor countries like Nigeria where prevention and adequate intervention are usually hampered by funds. In regions like Nigeria, it will be cheaper to prevent CKD than treating its complications. Hence, it is important to identify the common etiologies of CKD in Nigeria and prevent or promptly address them before causing irreversible damage to the kidneys. The most common cause of CKD in Nigeria includes hypertension, glomerulonephritis and diabetes mellitus. Many of these etiologies are preventable/treatable and should be looked for as a major way to reduce the incidence of CKD in Nigeria. Challenges identified in Nigeria, propagating CKD include westernization, inadequate manpower, late presentation, diagnostic challenge and poorly equipped facilities. Interventions like encouraging healthy lifestyle, making available essential drugs, training of health personnel, subsidized cost of treatment, legislation and policies to curb drug abuse. Therefore, resource-poor settings should focus on creating more awareness and making legislations and/or policies focused on these preventable causes of CKD as this is more realistic and effective in these settings.

Diabetes Mellitus Y Su Manejo En Escenarios Difíciles / Diabetes mellitus and its management in difficult scenarios

Introducción: la diabetes mellitus se produce por la alteración en el metabolismo de los carbohidratos, su prevalencia viene en aumento debido al incremento en la tasa de obesidad y los cambios en los hábitos nutricionales. En Colombia, alrededor de 8,36 % de la población padece diabetes tipo 2 y menos del 1 % diabetes tipo 1. Metodología: se seleccionaron 51 artículos sobre diabetes y diferentes escenarios clínicos, publicados en su mayoría entre los años 2015-2021. Resultados: en los pacientes con enfermedad hepática crónica, se aumenta la resistencia a la insulina e intolerancia a la glucosa; por esto, deben ser tratados en primera instancia con metformina o insulinas. En los diabéticos el riesgo cardiovascular se incrementa tanto para infarto como para accidente cerebrovascular. En estos, se puede realizar tratamiento con metformina, empagliflozina, entre otros. Los pacientes con falla renal tienen mayor riesgo de hipoglicemia por el metabolismo prolongado de la insulina como consecuencia de la filtración glomerular, en estos son útiles medicamentos como liraglutide y sus similares. Conclusión: existen múltiples escenarios clínicos que se presentan en conjunto con la diabetes mellitus. Se deben tener en cuenta las múltiples comorbilidades de los pacientes al momento de instaurar un tratamiento y sus diferentes determinantes, para garantizar su efectividad.

Introduction: Diabetes mellitus is caused by alterations in carbohydrate metabolism and its prevalence is increasing due to the increase in the rate of obesity and changes in nutritional habits. In Colombia, about 8.36% of the population suffers from type 2 diabetes and less than 1% from type 1 diabetes. Methods: Fifty-one articles were selected, on diabetes and different clinical scenarios, mostly published between 2015-2021. Results: In patients with chronic liver disease, insulin resistance and glucose intolerance are increased; therefore, they should be treated in the first instance with Metformin or Insulin. In diabetics, cardiovascular risk is increased for both infarction and stroke. In these patients, treatment can be performed with Metformin, Empagliflozin, among others. Patients with renal failure have a higher risk of hypoglycemia due to prolonged insulin metabolism as a consequence of glomerular filtration; medications such as Liraglutide and similar drugs are useful in these patients. Conclusion: There are multiple clinical scenarios that occur in conjunction with diabetes mellitus. The multiple comorbidities of patients should be taken into account when instituting treatment and its different determinants to ensure the effectiveness of the treatment to be appropriate for the patients.

ABSTRACT Objective: to understand the everyday life of adolescents and young people with chronic kidney disease undergoing hemodialysis treatment. Method: a qualitative research study of the Single Case Study type developed in a Renal Clinic from southern Brazil. Eight adolescents and young people aged between 18 and 24 years old undergoing hemodialysis treatment from February 5th, 2021, to January 26th, 2022. Data production was through semi-structured interviews, data from electronic medical records and participant observation through data triangulation. The observation was based on a script and field diary. The data were submitted to inductive thematic analysis and interpreted in the light of Agnes Heller's concept of everyday life. Results: the everyday life of adolescents and young people experiencing chronic kidney disease is impacted from the moment they receive the diagnosis until they understand their health situation. The changes imposed by the treatment and maintenance of the care measures have repercussions as limits faced in their everyday life. As for self-care, the major concern refers to the laboratory test levels. Conclusion: the everyday life of adolescents and young people on hemodialysis is permeated by unique changes in their existence and the construction of their own identity, added to the impact of the disease and the new condition imposed by the treatment. It is believed that the time they remain at the Clinic constitutes a strategy for health education, meeting the needs for diverse information about their chronic condition and treatment and contributing to the externalization of their humanity as a whole in this everyday routine.

Prevalence and factors associated with the severity of anaemia among patients on chronic haemodialysis in Lagos, Nigeria

Anaemia is a global public health problem with high mortality and morbidity. It is also a common consequence of chronic kidney disease (CKD). There is a paucity of data on the actual burden of anaemia among patients on chronic haemodialysis (CHD) in Lagos, Nigeria. Objectives: To determine the prevalence and factors associated with the severity of anaemia among Nigerian patients undergoing chronic haemodialysis. Methods: This was a retrospective analysis of adult patients with end-stage renal disease (ESRD) on maintenance haemodialysis at the Lagos State University Teaching Hospital, Ikeja, Lagos. The data extracted from the clinical case files included the bio-demographic and clinical parameters, including the treatment modalities. Results: A total of 92 patients comprising 69 (75%) males and 23 (25.0%) females with the overall mean age of 48.2±14.0 years were included. Hypertension was the commonest aetiology of CKD and the average duration of haemodialysis was 16.6 months. The commonest access route for haemodialysis was a central line while 96.7% and 81.5% received erythropoietin and intravenous iron sucrose respectively. Seventy-three (79.3%) patients have had intra-dialysis blood transfusions in the past. Mild, moderate, and severe anaemia were recorded in 17%, 67%, and 16% respectively. The use of erythropoietin, iron sucrose, and increased frequency of blood transfusions correlated with the severity of anaemia. Conclusion: Anaemia is highly prevalent among patients with CKD on chronic haemodialysis. Increased frequency of blood transfusions, inadequate utilization of erythropoietin, and iron sucrose administration are associated with anaemia severity.

Attitudes and influencing factors of transplantation-related populations towards kidney xenotransplantation / 器官移植

Objective To investigate the attitudes and influencing factors of transplantation-related populations towards kidney xenotransplantation. Methods From June 2022 to January 2023, stratified random sampling was performed from patients awaiting kidney transplantation, patients after kidney transplantation, patients' relatives and medical students. Four hundred subjects were collected from each population and 1600 subjects were investigated using a self-designed questionnaire. Baseline data of the respondents, their attitudes towards kidney xenotransplantation and the reasons of rejecting kidney xenotransplantation were analyzed. The influencing factors of attitudes towards kidney xenotransplantation were also identified. Results A total of 1 493 valid questionnaires were collected, and the questionnaire retrieval rate was 93.31%. About 93.10% of the respondents accepted allogeneic kidney transplantation, and 66.78% had heard of kidney xenotransplantation. Seven hundred and ninety-five respondents suggested that they could accept kidney xenotransplantation "when kidney xenotransplantation and allogeneic kidney transplantation yielded the same results and risks". Six hundred and ninety-eight respondents indicated that they were "unable" or "uncertain" whether they could accept kidney xenotransplantation (χ2=16.409，P=0.001). Among these 698 respondents, the proportion of them who were willing to accept kidney xenotransplantation when they did not meet the conditions of allogeneic kidney transplantation was 10.9%. About 35.8% of respondents were willing to accept kidney xenotransplantation if it yielded less risk and better prognosis compared with allogeneic kidney transplantation. If the time of awaiting kidney xenotransplantation was shorter than that of allogeneic kidney transplantation, 21.2% were willing to accept kidney xenotransplantation. If the cost of kidney xenotransplantation was less than that of allogeneic kidney transplantation, 24.5% of them were willing to accept kidney xenotransplantation. The main reasons of rejecting kidney xenotransplantation included surgical risk and other unknown risks. Multivariate analysis showed that respondents residing in cities and towns for a long period of time, those who accept allogeneic kidney transplantation and those who have heard of kidney xenotransplantation showed more positive attitudes towards kidney xenotransplantation. Conclusions Different transplantation-related populations have different attitudes towards kidney xenotransplantation, and the overall attitudes are positive. Active promotion of kidney xenotransplantation research and carrying out relevant popular science education contribute to improving public attitudes towards the acceptance of kidney xenotransplantation.

Clinical technical operation specification of kidney transplantation for autosomal dominant polycystic kidney disease (2022 edition) / 器官移植

Autosomal dominant polycystic kidney disease (ADPKD) is the most common inherited kidney disease and one of the most common causes for end-stage renal disease (ESRD). Kidney transplantation is the optimal renal replacement therapy for ADPKD patients complicated with ESRD. Currently, scholars at home and abroad have a certain controversy about whether polycystic kidney resection is necessary in ADPKD patients before kidney transplantation, and the criteria and methods for polycystic nephrectomy also differ. To further standardize the clinical technical operation of kidney transplantation in ADPKD patients, experts in organ transplantation organized by Branch of Organ Transplantation of Chinese Medical Association formulated this specification from the aspects of diagnosis of ADPKD, indications and contraindications of kidney transplantation for ADPKD, preoperative evaluation and treatment, polycystic nephrectomy, and postoperative management, etc.

Primary hyperoxaluria type II and organ transplantation / 器官移植

Primary hyperoxaluria type Ⅱ (PH2) is an inherited disorder of the glyoxylate metabolism caused by the gene mutation of glyoxylate reductase/hydroxypyruvate reductase (GRHPR). PH2 is characterized by recurrent nephrolithiasis and nephrocalcinosis, which may even progress into end-stage renal disease. Currently, organ transplantation is the only treatment option for PH2, which mainly includes two strategies: kidney transplantation and combined liver and kidney transplantation. Kidney transplantation yields a high risk of recurrence of oxalate nephropathy, which may cause early graft dysfunction. Combined liver and kidney transplantation could mitigate the deficiency of oxalate metabolism, whereas it yields a high risk of graft complications. PH2 is an extremely rare disorder. No consensus has been reached on the indications, surgical selection and perioperative management of organ transplantation for PH2 patients. In this article, the pathogenesis, diagnosis, monitoring and organ transplantation experience of PH2 were reviewed, aiming to divert clinicians' attention to PH2 and provide reference for determining diagnosis and treatment regimens, especially transplantation strategy for PH2 patients.

Effect of internal iliac artery calcification on delayed graft function and short-term prognosis of kidney transplant recipients / 器官移植

Objective To analyze the correlation between internal iliac artery calcification and delayed graft function (DGF) and short-term prognosis of kidney transplant recipients. Methods Clinical data of 222 kidney transplant recipients were retrospectively analyzed. According to the recovery of renal function, all recipients were divided into the DGF group (n=50) and immediate graft function (IGF) group (n=172). According to whether the recipients were complicated with severe internal iliac artery calcification, DGF and IGF groups were further divided into the high-risk DGF (n=22), low-risk DGF (n=28), high-risk IGF (n=41) and low-risk IGF(n=131) subgroups, respectively. Clinical data of donors and recipients were statistically compared between two groups. The incidences of postoperative DGF and internal iliac artery calcification were recorded. The risk factors of DGF after kidney transplantation, and the correlation between internal iliac artery calcification and clinical parameters were analyzed. Short-term prognosis of recipients with DGF complicated with severe internal iliac artery calcification was evaluated. Results The incidence of DGF was 22.5% (50/222). Among all recipients, 28.4% (63/222) were complicated with severe internal iliac artery calcification. In the DGF group, 44% (22/50) of the recipients were complicated with severe internal iliac artery calcification, higher than 23.8% (41/172) in the IGF group (P < 0.05). Univariate analysis showed that high serum creatinine (Scr) level of donors, male donor, high triglyceride level and severe internal iliac artery calcification of recipients were the risk factors for DGF after kidney transplantation (all P < 0.05). Multivariate logistic regression analysis revealed that Scr≥143 μmol/L of donors and severe internal iliac artery calcification of recipients were the independent risk factors for DGF after kidney transplantation (both P < 0.05). Correlation analysis indicated that internal iliac artery calcification was weakly correlated with the age of recipients and renal artery anastomosis (both P < 0.05). In the DGF group, the Scr level at postoperative 1 month was significantly higher, whereas the estimated glomerular filtration rate (eGFR) was significantly lower than those in the IGF group (both P < 0.05). The eGFR at postoperative 12 months in the high-risk DGF subgroup was significantly lower than those in the low-risk DGF, high-risk IGF and low-risk IGF subgroups (all P < 0.05). Conclusions Internal iliac artery calcification is not only a risk factor for recovery of renal allograft function, but also negatively affects short-term prognosis of renal allograft function.

Changes of spontaneous brain activity in end-stage renal disease patients: A study based on dynamic regional homogeneity / 西安交通大学学报(医学版)

【Objective】 To investigate dynamic regional homogeneity (dReHo) abnormality in end-stage renal disease (ESRD) patients by using resting-state functional magnetic resonance imaging (rs-fMRI). 【Methods】 A total of 26 ESRD patients and 26 healthy controls (HC) matched in gender, education level and age were included. Rs-fMRI scanning was performed in all subjects. All the subjects were tested by using auditory verbal learning test Huashan version (AVLT-H) and Montreal Cognitive Assessment (MoCA) to assess cognitive function before collection of MRI data. T-test was used to observe the difference in dReHo at global level between the two groups. Pearson and Spearman correlation analyses were made to estimate the correlation between abnormal brain regions and clinical scales. 【Results】 Compared with HC group, the dReHo value in ESRD patients reduced on the bilateral superior margin gyrus, left insula, left posterior central gyrus, and left putamen (P<0.05, replacement test correction). The dReHo values of left superior margin gyrus (r=-0.534, P=0.005) and left insula in ESRD patients (r=-0.422, P=0.032) were negatively correlated with the LR-S score, and the dReHo value of the left margin was negatively correlated with the SR-S score (r=-0.468, P=0.016). 【Conclusion】 There are abnormal dReHo values in several brain regions in ESRD patients during resting state, which is related to the patients’ cognitive function. The variation of dReHo value provides a new objective imaging basis for evaluating the cognitive function of ESRD patients.

Application Status and Research Progress of Palliative Care in Patients with End-stage Renal Disease / 中国医学伦理学

End-stage renal disease is the final stage of chronic kidney disease, and research on palliative care for end-stage renal disease patients in China is still in its infancy. The research content of palliative care for end-stage renal disease at home and abroad mainly includes identification and management of symptoms, advance care planning, psychosocial and spiritual support, and ethical issues in dialysis decision-making. However, practical experience is still insufficient. By focusing on the overview, development status, patient needs, as well as implementation forms and models of palliative care for endstage renal disease patients, this paper summarized the research progress and application status of related research, with a view to providing references for future domestic research and clinical practice in this field.

Early diagnosis value of peripheral blood PPARγ combined with IFN-γ detection for tuberculosis infection in patients with end-stage renal disease / 中国热带医学

@#Abstract: Objective　To explore the early diagnostic value of peripheral blood peroxisome proliferator-activated receptor γ (PPARγ) combined with γ-interferon (IFN-γ) release assay (IGRA) in the diagnosis of pulmonary tuberculosis in patients with end-stage renal disease (ESRD), and to provide reference for clinical diagnosis and treatment. Methods　From January 2019 to December 2021, 70 ESRD patients with suspicious symptoms of pulmonary tuberculosis were treated at Hebei Chest Hospital were selected as the research objects. According to the examination results, they were divided into ESRD group (40 cases) and ESRD complicated by pulmonary tuberculosis (40 cases, comorbidity group). In addition, 40 cases with pulmonary tuberculosis were used as the PTB group. All three groups of patients underwent IGRA test, and the peripheral blood PPARγ level was detected by enzyme-linked immunosorbent assay, and the diagnostic value of PPARγ combined with IGRA test for ESRD patients with pulmonary tuberculosis was explored. Results The expression level of PPARγ and IFN-γ content in the PTB group and the comorbidity group were obviously higher than those in the ESRD group (P<0.05), while the differences in PPARγ expression level and IFN-γ content between the PTB and comorbidity groups were not statistically significant (P>0.05). The ROC curve showed that the areas under the curve (AUC) of PPARγ and IGRA in the diagnosis of end-stage renal disease combined with tuberculosis were 0.823 (95%CI: 0.722-0.925) and 0.773 (95%CI: 0.662-0.883), respectively, and the AUC of combined detection was 0.928 (95%CI: 0.871-0.984), which was better than that of PPARγ and IGRA alone (Z/P=2.057/0.039, 2.843/0.005). The Kappa values of serum PPARγ and IGRA test compared with the clinical gold standard results in the diagnosis of ESRD complicated with pulmonary tuberculosis were 0.557 and 0.444 (P<0.05). The combined screening of ESRD with pulmonary tuberculosis was consistent with the clinical gold standard (Kappa=0.661, P<0.05). Among the 30 ESRD patients complicated with pulmonary tuberculosis, the sensitivity of PPARγ combined with IGRA test in diagnosis of ESRD complicated with pulmonary tuberculosis was 93.33% (28/30), which was higher than 70.00% (21/30) of PPARγ and 66.67% (20/30) of IGRA test alone (P<0.05). Conclusions Peripheral blood PPARγ and IGRA tests have certain diagnostic value for ESRD complicated with tuberculosis, and the combined detection of the two can improve the sensitivity and reduce the rate of missed diagnosis, which is worthy of clinical promotion.
