Gut microbiota is often modified after kidney transplantation.This principally happens in the first period after transplantation.Antibiotics and,most of all,immunosuppressive drugs are the main responsible.The relationship between immunosuppressive drugs and the gut microbiota is bilateral.From one side immunosuppressive drugs modify the gut microbiota,often generating dysbiosis;from the other side microbiota may interfere with the immunosuppressant pharmacokinetics,producing products more or less active with respect to the original drug.These phenomena have influence over the graft outcomes and clinical consequences as rejections,infections,diarrhea may be caused by the dysbiotic condition.Corticosteroids,calcineurin inhibitors such as tacrolimus and cyclosporine,mycophenolate mofetil and mTOR inhibitors are the immunosuppressive drugs whose effect on the gut microbiota is better known.In contrast is well known how the gut microbiota may interfere with glucocorticoids,which may be transformed into androgens.Tacrolimus may be transformed by microbiota into a product called M1 that is 15-fold less active with respect to tacrolimus.The pro-drug mycophenolate mofetil is normally transformed in mycophenolic acid that according the presence or not of microbes producing the enzyme glucuronidase,may be transformed into the inactive product. 展开更多

Kidney transplantation(KT),although the best treatment option for eligible patients,entails maintaining and adhering to a life-long treatment regimen of medications,lifestyle changes,self-care,and appointments.Many patients experience uncertain outcome trajectories increasing their vulnerability and symptom burden and generating complex care needs.Even when transplants are successful,for some patients the adjustment to life post-transplant can be challenging and psychological difficulties,economic challenges and social isola-tion have been reported.About 50%of patients lose their transplant within 10 years and must return to dialysis or pursue another transplant or conservative care.This paper documents the complicated journey patients undertake before and after KT and outlines some initiatives aimed at improving patient-centered care in transplantation.A more cohesive approach to care that borrows its philosophical approach from the established field of supportive oncology may improve patient experiences and outcomes.We propose the"supportive care in transplantation"care model to operationalize a patient-centered approach in transplantation.This model can build on other ongoing initiatives of other scholars and researchers and can help advance patient-centered care through the entire care continuum of kidney transplant recipients and candidates.Multi-dimensionality,multi-disciplinarity and evidence-based approaches are proposed as other key tenets of this care model.We conclude by proposing the potential advantages of this approach to patients and healthcare systems.Core Tip:Kidney transplant recipients and candidates face several uncertainties in their care journey and have several expressed unmet healthcare needs.We recommend a structured and comprehensive approach to transplant care across the entire continuum of a transplant patient’s journey similar to what has been developed in the field of oncology.The supportive care in transplantation model can operationalize patient-centered care and build on the efforts of other researchers in the field.We postulate that such a model would significantly improve care delivery and patients’experiences and outcomes and potentially decrease healthcare utilization and cost.INTRODUCTION Patients with kidney failure benefit from(KT)[1,2],and experience improved survival rates when compared with dialysis[3-6].KT studies,using validated instruments,have also consistently demonstrated that kidney transplant recipients(KTRs)experience better health-related quality of life and several improvements in other disease-specific domains when compared with dialysis[7].In countries where dialysis is out of reach for many,the diagnosis of kidney failure would be futile without KT[8].Thus,increasing KT has been a priority for the nephrology and transplant communities.This priority has been reflected in recent global trends:Of the 79 countries where data were available,the International Society of Nephrology’s Global Kidney Atlas reported that the prevalence of KTRs in 2023 was 279 per million population which represented an increase of 9.4%from the data published four years prior[8].Despite this growth,KT can be a challenging journey for many patients and it is sometimes regarded as a‘cure’,which does not conform with the reality that many patients experience[9-13].KTRs must maintain a life-long treatment regimen of medications,lifestyle changes,self-care and medical appointments[14-17].As poignantly stated by a young female transplant recipient,“I thought everything would change once I got my kidney.I thought I would be healthy again”but after experiencing multiple side effects of immunosuppressive medications and graft loss,she stated,“I am just a different kind of patient now”[18].Indeed,a significant proportion of patients experience graft failure and return to dialysis;it is estimated that over 50%return to dialysis within 10 years of KT[19-23].Patients are often not prepared for this outcome and report several psychosocial and physical ramifications of graft failure[24,25].Overall,high symptom burden,adverse effects of immunosuppressants,risk of graft rejection or failure and mortality,contribute to complex needs,vulnerability and uncertainties for patients,increasing their care needs and treatment burden[26-30].In this paper,we highlight the complex journey that KTRs and candidates undertake that can generate varied outcome trajectories and complex healthcare needs.We highlight the need for a comprehensive patient-centered approach to care and conclude with a proposal for a“supportive care in transplantation”care model. 展开更多

Kidney transplantation is the best option for kidney replacement therapy,even considering that most of the times the grafts do not survive as long as their recipients.In the Khalil et al's experience,published in this issue of the Journal,they analyze their second kidney graft survival and describe those significant predictors of early loss.This editorial comments on the results and put in perspective that most of the times,long-term graft survival could be inadvertently jeopardized if the immunosuppressive therapy is reduced or withdrawn for any reason,and that it could happen frequently if the transplant physician intends to innovate with the clinical care without proper evidence-based data. 展开更多

Traditional monitoring of kidney transplant recipients for allograft dysfunction caused by rejection involves serial checks of serum creatinine with biopsy of the renal allograft if dysfunction is suspected.This approach is labor-intensive,invasive and costly.In addition,because this approach relies on a rise in serum creatinine above historical baselines,injury to the allograft can be extensive before this rise occurs.In an effort to address this,donor-derived cell-free DNA(dd-cf DNA)is being used with increasing frequency in the clinical setting as a means of diagnosing a rejection of the renal allograft early in the course.This can poten-tially allow for early intervention to minimize not only injury,but the intensity of antirejection therapy needed and the avoidance of side effects.Here,we will review the available methodology for the determination and quantification of dd-cf DNA,the data supporting its use in clinical practice and the limitations of this technology. 展开更多

Famure et al describe that close to 50%of their patients needed early or very early hospital readmissions after their kidney transplantation.As they taught us the variables related to those outcomes,we describe eight teaching capsules that may go beyond what they describe in their article.First two capsules talk about the ideal donors and recipients we should choose for avoiding the risk of an early readmission.The third and fourth capsules tell us about the reality of cadaveric donors and recipients with comorbidities,and the way transplant physicians should choose them to maximize survival.Fifth capsule shows that any mistake can result in an early readmission,and thus,in poorer outcomes.Sixth capsule talks about economic losses of early readmissions,cost-effectiveness of tran-splantation,and how to improve outcomes and reduce costs by managing a risky patient-portfolio.Seventh capsule argues about knowing your risk behavior to better manage your portfolio;and Eighth capsule about the importance of the center experience in transplanting complex patients.We finish with some lessons of the importance of the transplantation process and the collaboration with other disciplines in order to prevent the conditions that lead to early readmissions. 展开更多

Kidney transplantation(KT)is the optimal form of renal replacement therapy for patients with end-stage renal diseases.However,this health service is not available to all patients,especially in developing countries.The deceased donor KT programs are mostly absent,and the living donor KT centers are scarce.Single-center studies presenting experiences from developing countries usually report a variety of challenges.This review addresses these challenges and the opposing strategies by reviewing the single-center experiences of developing countries.The financial challenges hamper the infrastructural and material availability,coverage of transplant costs,and qualification of medical personnel.The sociocultural challenges influence organ donation,equity of beneficence,and regular follow-up work.Low interests and motives for transplantation may result from high medicolegal responsibilities in KT practice,intense potential psychosocial burdens,complex qualification protocols,and low productivity or compensation for KT practice.Low medical literacy about KT advantages is prevalent among clinicians,patients,and the public.The inefficient organizational and regulatory oversight is translated into inefficient healthcare systems,absent national KT programs and registries,uncoordinated job descriptions and qualification protocols,uncoordinated on-site investigations with regulatory constraints,and the prevalence of commercial KT practices.These challenges resulted in noticeable differences between KT services in developed and developing countries.The coping strategies can be summarized in two main mechanisms:The first mechanism is maximizing the available resources by increasing the rates of living kidney donation,promoting the expertise of medical personnel,reducing material consumption,and supporting the establishment and maintenance of KT programs.The latter warrants the expansion of the public sector and the elimination of non-ethical KT practices.The second mechanism is recruiting external resources,including financial,experience,and training agreements. 展开更多

BACKGROUND There is no data evaluating the impact of Medicaid expansion on kidney tran-splants(KT)in Oklahoma.AIM To investigate the impact of Medicaid expansion on KT patients in Oklahoma.METHODS The UNOS database was utilized to evaluate data pertaining to adult KT reci-pients in Oklahoma in the pre-and post-Medicaid eras.Bivariate analysis,Kaplan Meier analysis was used to estimate,and cox proportional models were utilized.RESULTS There were 2758 pre-and 141 recipients in the post-Medicaid expansion era.Post-expansion patients were more often non-United States citizens(2.3%vs 5.7%),American Indian,Alaskan,or Pacific Islander(7.8%vs 9.2%),Hispanic(7.4%vs 12.8%),or Asian(2.5%vs 8.5%)(P<0.0001).Waitlist time was shorter in the post-expansion era(410 vs 253 d)(P=0.0011).Living donor rates,pre-emptive transplants,re-do transplants,delayed graft function rates,kidney donor profile index values,panel reactive antibodies levels,and insurance types were similar.Patients with public insurance were more frail.Despite increased early(<6 months)rejection rates,1-year patient and graft survival were similar.In Cox proportional hazards model,male sex,American Indian,Alaskan or Pacific Islander race,public insurance,and frailty category were independent risk factors for death at 1 year.Medicaid expansion was not associated with graft failure or patient survival(adjusted hazard ratio:1.07;95%CI:0.26-4.41).CONCLUSION Medicaid expansion in Oklahoma is associated with increased KT access for non-White/non-Black and non-United States citizen patients with shorter wait times.1-year graft and patient survival rates were similar before and after expansion.Medicaid expansion itself was not independently associated with graft or patient survival outcomes.Ongoing research is necessary to determine the long-term effects of Medicaid expansion. 展开更多

Objective Delayed graft function(DGF)and early graft loss of renal grafts are determined by the quality of the kidneys from the deceased donor.As“non-traditional”risk factors,serum biomarkers of donors,such as lipids and electrolytes,have drawn increasing attention due to their effects on the postoperative outcomes of renal grafts.This study aimed to examine the value of these serum biomarkers for prediction of renal graft function.Methods The present study consecutively collected 306 patients who underwent their first single kidney transplantation(KT)from adult deceased donors in our center from January 1,2018 to December 31,2019.The correlation between postoperative outcomes[DGF and abnormal serum creatinine(SCr)after 6 and 12 months]and risk factors of donors,including gender,age,body mass index(BMI),past histories,serum lipid biomarkers[cholesterol,triglyceride,high-density lipoprotein(HDL)and low-density lipoprotein(DL)],and serum electrolytes(calcium and sodium)were analyzed and evaluated.Results(1)Donor age and pre-existing hypertension were significantly correlated with the incidence rate of DGF and high SCr level(≥2 mg/dL)at 6 and 12 months after KT(P<0.05);(2)The donor’s BMI was significantly correlated with the incidence rate of DGF after KT(P<0.05);(3)For serum lipids,merely the low level of serum HDL of the donor was correlated with the reduced incidence rate of high SCr level at 12 months after KT[P<0.05,OR(95%CI):0.425(0.202–0.97)];(4)The serum calcium of the donor was associated with the reduced incidence rate of high SCr level at 6 and 12 months after KT[P<0.05,OR(95%CI):0.184(0.045–0.747)and P<0.05,OR(95%CI):0.114(0.014–0.948),respectively].Conclusion The serum HDL and calcium of the donor may serve as predictive factors for the postoperative outcomes of renal grafts after KT,in addition to the donor’s age,BMI and pre-existing hypertension. 展开更多

BACKGROUND Preemptive living donor kidney transplantation(PLDKT)is recommended as the optimal treatment for end-stage renal disease.AIM To assess the rate of PLDKT among patients who accessed KT in our center and review the status of PLDKT in Egypt.METHODS We performed a retrospective review of the patients who accessed KT in our center from November 2015 to November 2022.In addition,the PLDKT status in Egypt was reviewed relative to the literature.RESULTS Of the 304 patients who accessed KT,32 patients(10.5%)had preemptive access to KT(PAKT).The means of age and estimated glomerular filtration rate were 31.7±13 years and 12.8±3.5 mL/min/1.73 m2,respectively.Fifty-nine patients had KT,including 3 PLDKTs only(5.1%of total KTs and 9.4%of PAKT).Twenty-nine patients(90.6%)failed to receive PLDKT due to donor unavailability(25%),exclusion(28.6%),regression from donation(3.6%),and patient regression on starting dialysis(39.3%).In multivariate analysis,known primary kidney disease(P=0.002),patient age(P=0.031)and sex(P=0.001)were independent predictors of achievement of KT in our center.However,PAKT was not significantly(P=0.065)associated with the achievement of KT.Review of the literature revealed lower rates of PLDKT in Egypt than those in the literature.CONCLUSION Patient age,sex,and primary kidney disease are independent predictors of achieving living donor KT.Despite its non-significant effect,PAKT may enhance the low rates of PLDKT.The main causes of non-achievement of PLDKT were patient regression on starting regular dialysis and donor unavailability or exclusion. 展开更多

BACKGROUND Early hospital readmissions(EHRs)after kidney transplantation range in incidence from 18%-47%and are important and substantial healthcare quality indicators.EHR can adversely impact clinical outcomes such as graft function and patient mortality as well as healthcare costs.EHRs have been extensively studied in American healthcare systems,but these associations have not been explored within a Canadian setting.Due to significant differences in the delivery of healthcare and patient outcomes,results from American studies cannot be readily applicable to Canadian populations.A better understanding of EHR can facilitate improved discharge planning and long-term outpatient management post kidney transplant.AIM To explore the burden of EHR on kidney transplant recipients(KTRs)and the Canadian healthcare system in a large transplant centre.METHODS This single centre cohort study included 1564 KTRs recruited from January 1,2009 to December 31,2017,with a 1-year follow-up.We defined EHR as hospitalizations within 30 d or 90 d of transplant discharge,excluding elective procedures.Multivariable Cox and linear regression models were used to examine EHR,late hospital readmissions(defined as hospitalizations within 31-365 d for 30-d EHR and within 91-365 d for 90-d EHR),and outcomes including graft function and patient mortality.RESULTS In this study,307(22.4%)and 394(29.6%)KTRs had 30-d and 90-d EHRs,respectively.Factors such as having previous cases of rejection,being transplanted in more recent years,having a longer duration of dialysis pretransplant,and having an expanded criteria donor were associated with EHR post-transplant.The cumulative probability of death censored graft failure,as well as total graft failure,was higher among the 90-d EHR group as compared to patients with no EHR.While multivariable models found no significant association between EHR and patient mortality,patients with EHR were at an increased risk of late hospital readmissions,poorer kidney function throughout the 1st year post-transplant,and higher hospital-based care costs within the 1st year of follow-up.CONCLUSION EHRs are associated with suboptimal outcomes after kidney transplant and increased financial burden on the healthcare system.The results warrant the need for effective strategies to reduce post-transplant EHR. 展开更多

Diabetic kidney disease(DKD)is a common complication of diabetes mellitus that contributes to the risk of end-stage kidney disease(ESKD).Wide glycemic var-iations,such as hypoglycemia and hyperglycemia,are broadly found in diabetic patients with DKD and especially ESKD,as a result of impaired renal metabolism.It is essential to monitor glycemia for effective management of DKD.Hemoglobin A1c(HbA1c)has long been considered as the gold standard for monitoring glycemia for>3 months.However,assessment of HbA1c has some bias as it is susceptible to factors such as anemia and liver or kidney dysfunction.Continuous glucose monitoring(CGM)has provided new insights on glycemic assessment and management.CGM directly measures glucose level in interstitial fluid,reports real-time or retrospective glucose concentration,and provides multiple glycemic metrics.It avoids the pitfalls of HbA1c in some contexts,and may serve as a precise alternative to estimation of mean glucose and glycemic variability.Emerging studies have demonstrated the merits of CGM for precise monitoring,which allows fine-tuning of glycemic management in diabetic patients.Therefore,CGM technology has the potential for better glycemic monitoring in DKD patients.More research is needed to explore its application and management in different stages of DKD,including hemodialysis,peritoneal dialysis and kidney transplantation. 展开更多

BACKGROUND Prolonged symptoms after corona virus disease 2019(Long-COVID) in dialysisdependent patients and kidney transplant(KT) recipients are important as a possible risk factor for organ dysfunctions,especially gastrointestinal(GI)problems,during immunosuppressive therapy.AIM To identify the characteristics of GI manifestations of Long-COVID in patients with dialysis-dependent or KT status.METHODS This observational,prospective study included patients with COVID-19 infection,confirmed by reverse transcription polymerase chain reaction,with the onset of symptoms between 1 January 2022 and 31 July 2022 which was explored at 3 mo after the onset,either through the out-patient follow-up or by telephone interviews.RESULTS The 645 eligible participants consisted of 588 cases with hemodialysis(HD),38 patients with peritoneal dialysis(PD),and 19 KT recipients who were hospitalized with COVID-19 infection during the observation. Of these,577(89.5%) cases agreed to the interviews,while 64(10.9%)patients with HD and 4(10.5%) cases of PD were excluded. The mean age was 52 ± 11 years with 52% women. The median dialysis duration was 7 ± 3 and 5 ± 1 years for HD and PD groups,respectively,and the median time post-transplantation was 6 ± 2 years. Long-COVID was identified in 293/524(56%) and 21/34(62%) in HD and PD,respectively,and 7/19(37%) KT recipients. Fatigue was the most prevalent(96%) of the non-GI tract symptoms,whereas anorexia(90.9%),loss of taste(64.4%),and abdominal pain(62.5%) were the first three common GI manifestations of Long-COVID. Notably,there were 6 cases of mesenteric panniculitis from 19patients with GI symptoms in the KT group.CONCLUSION Different from patients with non-chronic kidney disease,there was a high prevalence of GI manifestations of Long-COVID in dialysis-dependent patients and KT recipients. An appropriate long-term follow-up in these vulnerable populations after COVID-19 infection is possibly necessary. 展开更多

Chronic kidney disease(CKD),especially in advanced stages,is an important cause of infertility.In CKD patients,infertility has been linked to multiple factors.The pathophysiology of infertility related to CKD is complex and forked.Correction of modifiable factors can improve fertility in both genders.In males as well as females,successful kidney transplantation offers good chances of restoration of reproductive function.In female renal allograft recipients,recovery of reproductive functions in the post-transplant period will manifest as restoration of normal menses and ovulation.Owing to this improvement,there is a significant risk of unplanned pregnancy,hence the need to discuss methods of contraception before transplantation.In kidney transplant recipients,different contraceptive options for pregnancy planning,have been used.The selection of one contraception over another is based on preference and tolerability.Pregnancy,in renal transplanted females,is associated with physiologic changes that occur in pregnant women with native kidneys.Immunosuppressive medications during pregnancy,in a recipient with a single functioning kidney,expose the mother and fetus to unwanted complications.Some immunosuppressive drugs are contraindicated during pregnancy.Immunosuppressive medications should be discussed with renal transplant recipients who are planning to breastfeed their babies.In addition to antirejection drugs,other medications should be managed accordingly,whenever pregnancy is planned. 展开更多

Liver diseases after kidney transplantation range from mild biochemical abnormalities to severe hepatitis or cirrhosis.The causes are diverse and mainly associated with hepatotropic viruses,drug toxicity and metabolic disorders.Over the past decade,the aetiology of liver disease in kidney recipients has changed significantly.These relates to the use of direct-acting antiviral agents against hepatitis C virus,the increasing availability of vaccination against hepatitis B and a better understanding of drug-induced hepatotoxicity.In addition,the emergence of the severe acute respiratory syndrome coronavirus 2 pandemic has brought new challenges to kidney recipients.This review aims to provide healthcare professionals with a comprehensive understanding of recent advances in the management of liver complications in kidney recipients and to enable them to make informed decisions regarding the risks and impact of liver disease in this population. 展开更多

BACKGROUND Warts are common in recipients of kidney transplantation(KT).Resistant warts which are not amenable to conventional therapies may lead to significant morbidity.Limited data exists on safety and efficacy of local immunotherapy among immunocompromised KT recipients.CASE SUMMARY We report a seven-year-old child who presented with recalcitrant plantar periungual warts in the early KT period.Immunosuppression consisted of tacrolimus,mycophenolate and steroid.Due to failure of conventional anti-wart therapies,he was treated with two sessions of intralesional(IL)candida immunotherapy along with liquid nitrogen cryotherapy leading to complete resolution of the warts.Interestingly,de novo BK viremia was seen about three weeks following the last candida immunotherapy.This required reduction of immunosuppression and other anti-BK viral therapies.Allograft function remained stable but there were donor specific antibodies detected.There also was elevated level of plasma donor derived cell-free DNA.A pneumocystis jirovecii pneumonia occurred ten months following completion of immunotherapy that was successfully treated with trimethoprim-sulfamethoxazole.During this ten-month follow-up period,there have been no recurrence of warts,and transplant kidney function has remained stable.CONCLUSION Stimulation of cell-mediated immunity against the human papilloma virus induced by the IL candida immunotherapy is thought to be a cause for wart resolution.With this therapy,whether it is necessary to augment the immunosuppression to prevent rejection is unclear as that may come with a risk of infectious complications.Larger,prospective studies in pediatric KT recipients are needed to explore these important issues. 展开更多

BACKGROUND Since its initial detection in 2019,coronavirus disease 2019(COVID-19)pneumonia has rapidly spread throughout the world in a global pandemic.However,reports of COVID-19 pneumonia among patients following kidney transplantation have been limited and no uniform treatment guidelines for these patients have yet to be established.CASE SUMMARY Here,we report the case of a 39-year-old patient recovering from kidney transplantation who contracted perioperative COVID-19 pneumonia that was successfully controlled with oral paxlovid and a single intravenous drip infusion of tocilizumab following the discontinuation of immunosuppressive drugs.CONCLUSION Given the rapid spread of severe acute respiratory syndrome coronavirus 2 infections,clinicians should be aware of the potential for more cases of COVID-19 among patients following kidney transplantation and be familiar with appropriate treatment options and likely clinical outcomes. 展开更多

BACKGROUND Kidney transplantation is the standard treatment for end-stage renal disease.Particularly,rare and specific pathogenic infections which are asymptomatic are often difficult to diagnose,causing delayed and ineffective treatment and thus seriously affecting prognosis.Tropheryma whipplei(T.whipplei)is a Gram-positive actinomycete widely found in soil,sewage,and other external environments and is present in the population as an asymptomatic pathogen.There is relatively little documented research on T.whipplei in renal transplant patients,and there are no uniform criteria for treating this group of post-transplant patients.This article describes the treatment of a 42-year-old individual with post-transplant T.whipplei infection following kidney transplantation.CASE SUMMARY To analyze clinical features of Whipple’s disease and summarize its diagnosis and treatment effects after renal transplantation.Clinical data of a Whipple’s disease patient treated in the affiliated hospital of Guizhou Medical University were collected and assessed retrospectively.The treatment outcomes and clinical experience were then summarized via literature review.The patient was admitted to the hospital due to recurrent diarrhea for 1 mo,shortness of breath,and 1 wk of fever,after 3 years of renal transplantation.The symptoms of the digestive and respiratory systems were not significantly improved after adjusting immunosuppressive regimen and anti-diarrheal,empirical antibiotic treatments.Bronchoscopic alveolar fluid was collected for meta-genomic next-generation sequencing(mNGS).The deoxyribonucleic acid sequence of Tropheryma whipplei was detected,and Whipple’s disease was diagnosed.Meropenem,ceftriaxone,and other symptomatic treatments were given,and water-electrolyte balance was maintained.Symptoms resolved quickly,and the patient was discharged after 20 d of hospitalization.The compound sulfamethoxazole tablet was continued for 3 mo after discharge.No diarrhea,fever,and other symptoms occurred during the 6-month follow-up.CONCLUSION Whipple’s disease is rare,with no specific symptoms,which makes diagnosis difficult.Polymerase chain reaction or mNGS should be immediately performed when the disease is suspected to confirm the diagnosis. 展开更多

BACKGROUND The increasing kidney retransplantation rate has created a parallel field of research,including the risk factors and outcomes of this advanced form of renal replacement therapy.The presentation of experiences from different kidney transplantation centers may help enrich the literature on kidney retransplantation,as a specific topic in the field of kidney transplantation.AIM To identify the risk factors affecting primary graft function and graft survival rates after second kidney transplantation(SKT).METHODS The records of SKT cases performed between January 1977 and December 2014 at a European tertiary-level kidney transplantation center were retrospectively reviewed and analyzed.Beside the descriptive characteristics,the survivals of patients and both the first and second grafts were described using Kaplan-Meier curves.In addition,Kaplan-Meier analyses were also used to estimate the survival probabilities at 1,3,5,and 10 post-operative years,as well as at the longest followup duration available.Moreover,bivariate associations between various predictors and the categorical outcomes were assessed,using the suitable biostatistical tests,according to the predictor type.RESULTS Out of 1861 cases of kidney transplantation,only 48 cases with SKT were eligible for studying,including 33 men and 15 women with a mean age of 42.1±13 years.The primary non-function(PNF)graft occurred in five patients(10.4%).In bivariate analyses,a high body mass index(P=0.009)and first graft loss due to acute rejection(P=0.025)were the only significant predictors of PNF graft.The second graft survival was reduced by delayed graft function in the first(P=0.008)and second(P<0.001)grafts.However,the effect of acute rejection within the first year after the first transplant did not reach the threshold of significance(P=0.053).The mean follow-up period was 59.8±48.6 mo.Censored graft/patient survival rates at 1,3,5 and 10 years were 90.5%/97.9%,79.9%/95.6%,73.7%/91.9%,and 51.6%/83.0%,respectively.CONCLUSION Non-immediate recovery modes of the first and second graft functions were significantly associated with unfavorable second graft survival rates.Patient and graft survival rates of SKT were similar to those of the first kidney transplantation. 展开更多

Type 1 diabetes mellitus(T1DM)is one of the important causes of chronic kidney disease(CKD)and end-stage renal failure(ESRF).Even with the best available treatment options,management of T1DM poses significant challenges for clinicians across the world,especially when associated with CKD and ESRF.Substantial increases in morbidity and mortality along with marked rise in treatment costs and marked reduction of quality of life are the usual consequences of onset of CKD and progression to ESRF in patients with T1DM.Simultaneous pancreas-kidney transplant(SPK)is an attractive and promising treatment option for patients with advanced CKD/ESRF and T1DM for potential cure of these diseases and possibly several complications.However,limited availability of the organs for transplantation,the need for long-term immunosuppression to prevent rejection,peri-and post-operative complications of SPK,lack of resources and the expertise for the procedure in many centers,and the cost implications related to the surgery and postoperative care of these patients are major issues faced by clinicians across the globe.This clinical update review compiles the latest evidence and current recommendations of SPK for patients with T1DM and advanced CKD/ESRF to enable clinicians to care for these diseases. 展开更多

Objective:Compared with long-term renal replacement therapy,kidney transplantation is the ideal treatment for end-stage renal disease(ESRD),significantly extending patient life and improving quality of life.Kidney transplant patients need to adhere to lifelong immunosuppressive medication regimens,but their medication adherence is generally poor compared with other organ transplant recipients.Medication adherence is closely related to medication literacy and psychological status,yet related studies are limited.This study aims to investigate the current status of medication adherence,inner strength,and medication literacy in kidney transplant patients,analyze the relationships among these 3 factors,and explore the mediating role of inner strength in the relationship between medication literacy and medication adherence.Methods:A cross-sectional survey was conducted from March to October 2023 involving 421 patients aged≥18 years who visited kidney transplantation outpatient clinics at 4 tertiary hospitals in Hunan Province.The inner strength,medication literacy,and medication adherence of kidney transplant patients were investigated using the Inner Strength Scale(ISS),the Chinese version of the Medication Literacy Assessment in Spanish and English(MedLitRxSE),and the Chinese version of the Morisky Medication Adherence Scale-8(C-MMAS-8),respectively.Univariate analysis was performed to examine the effects of demographic and clinical data on medication adherence.Correlation analysis was conducted to explore the relationships among medication literacy,medication adherence,and inner strength.Significant variables from univariate and correlation analyses were further analyzed using multiple linear regression,and the mediating effect of inner strength was explored.Results:Among the 421 questionnaires collected,408 were valid,with an effective rate of 96.91%.The scores of C-MMAS-8,MedLitRxSE,and ISS were 6.64±1.16,100.63±14.67,and 8.47±4.03,respectively.Among the 408 patients,only 86(21.08%)patients had a high level of medication adherence,whereas 230(56.37%)patients had a medium level of medication adherence,and 92(22.55%)patients had poor medication adherence.Univariate analysis indicated that the kidney transplant patients’age,marital status,education levels,years since their kidney transplant operation,number of hospitalizations after the kidney transplant,and adverse drug reactions showed significant differences in medication adherence(all P<0.05).Correlation analysis showed that inner strength positively correlated with both medication literacy(r=0.183,P<0.001)and medication adherence(r=0.201,P<0.001).Additionally,there was a positive correlation between medication adherence and medication literacy(r=0.236,P<0.001).Inner strength accounted for 13.22%of the total effect in the mediating role between medication literacy and medication adherence.Conclusion:The level of medication adherence among kidney transplant patients needs improvement,and targeted intervention measures are essential.Inner strength mediates the relationship between medication literacy and medication adherence in these patients.Healthcare professionals should focus on enhancing medication literacy and supporting patients’inner strength to improve medication adherence. 展开更多
