Supportive care in transplantation: A patient-centered care model to better support kidney transplant candidates and recipients

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.

Preemptive living donor kidney transplantation:Access,fate,and review of the status in

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.

Update on the reciprocal interference between immunosuppressive therapy and gut microbiota after kidney transplantation

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.

Predicting outcomes after kidney transplantation: Can Pareto’s rules help us to do so?

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.

Challenges to establishing and maintaining kidney transplantation programs in developing countries:What are the coping strategies?

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.

Clinical use of donor-derived cell-free DNA in kidney transplantation

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.

Kidney transplantation outcomes: Is it possible to improve when good results are falling down?

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.

Impact of Medicaid expansion on kidney transplantation in the State Oklahoma

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.

Thrombotic microangiopathy after kidney transplantation: Expanding etiologic and pathogenetic spectra

Thrombotic microangiopathy(TMA)is an uncommon but serious complication that not only affects native kidneys but also transplanted kidneys.This review is specifically focused on post-transplant TMA(PT-TMA)involving kidney transplant recipients.Its reported prevalence in the latter population varies from 0.8%to 14%with adverse impacts on both graft and patient survival.It has many causes and associations,and the list of etiologic agents and associations is growing constantly.The pathogenesis is equally varied and a variety of pathogenetic pathways lead to the development of microvascular injury as the final common pathway.PT-TMA is categorized in many ways in order to facilitate its management.Ironically,more than one causes are contributory in PT-TMA and it is often difficult to pinpoint one particular cause in an individual case.Pathologically,the hallmark lesions are endothelial cell injury and intravascular thrombi affecting the microvasculature.Early diagnosis and classification of PT-TMA are imperative for optimal outcomes but are challenging for both clinicians and pathologists.The Banff classification has addressed this issue and has developed minimum diagnostic criteria for pathologic diagnosis of PT-TMA in the first phase.Management of the condition is also challenging and still largely empirical.It varies from simple maneuvers,such as plasmapheresis,drug withdrawal or modification,or dose reduction,to lifelong complement blockade,which is very expensive.A thorough understanding of the condition is imperative for an early diagnosis and quick treatment when the treatment is potentially effective.This review aims to increase the awareness of relevant stakeholders regarding this important,potentially treatable but under-recognized cause of kidney allograft dysfunction.

Disorders of potassium homeostasis after kidney transplantation

Disturbances of potassium balance are often encountered when managing kidney transplant recipients(KTR).Both hyperkalemia and hypokalemia may present either as medical emergencies or chronic outpatient abnormalities.Despite the high incidence of hyperkalemia and its potential life-threatening implications,consensus on its management in KTR is lacking.Hypokalemia in KTR is also well-described,although it is given less attention by clinicians compared to hyper-kalemia.This article discusses the etiology,pathophysiology and management of both types of potassium disorders in KTR.Once any emergent situation has been corrected,treatment approaches include correcting insulin deficiency if present,adjusting non-immunosuppressive and immunosuppressive medications,elimi-nating or supplementing potassium as needed,and dietary counselling.Although commonly of multifactorial etiology,ascertaining the specific cause in a particular patient will help guide successful management.Monitoring KTR through regular laboratory testing is essential to detect serious disturbances in potassium balance since patients are often asymptomatic.

Predictors of graft function and survival in second kidney transplantation: A single center experience

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.

Impact of Vascular Variations on Living Donor Kidney Transplantation

Background: Kidney transplantation is the best treatment for end-stage chronic kidney disease. However, its realization is confronted by several difficulties among which are anatomical variations. Objective: The objective of our work was to describe the impact of renal pedicle variations on the operative procedure as well as the complications. Method: We conducted a retrospective study on living kidney donors and their recipients in the period from 2012 to 2017. Several variables were studied, in particular socio-demographic, operative and progression. Results: We identified 49 living donors whose mean age was 37.59 years with a male-to-female ratio of 3.9 and 45 ± 10.75 years in the recipients. The prevalence of renal vascular abnormalities was higher with a proportion of 46.94% in recipients. The left kidney was most frequently removed (75.51%) and then kept mainly in HTK (95.92%). These vascular anomalies were associated with a longer operating time but this difference was not statistically significant (p = 0.5804). They had no effect on hot and cold ischemia times (p = 0.9838, p = 0.8389). Complications were observed in 11 patients, all recipients, i.e. 11.22%, and were not related to the presence of vascular abnormalities (p = 0.086). We observed that 4.08% of deaths were all recipients. Conclusion: It seems that kidney transplantation with multiple renal arteries and/or veins does not significantly lengthen the operating time and does not promote the onset of complications.

Infertility,pregnancy and breastfeeding in kidney transplantation recipients:Key issues

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.

Simultaneous pancreas-kidney transplantation for end-stage renal failure in type 1 diabetes mellitus: Current perspectives

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.

Values of Donor Serum Lipids and Calcium in Predicting Graft Function after Kidney Transplantation:A Retrospective Study

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.

Shifting perspectives in liver diseases after kidney transplantation

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.

Efficacy and safety of local candida immunotherapy in recalcitrant warts in pediatric kidney transplantation:A case report

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.

Successful treatment of a case of COVID-19 pneumonia following kidney transplantation using paxlovid and tocilizumab

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.

Diagnosis and treatment of Whipple disease after kidney transplantation:A case report

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.

The Relationship between the intolerance of uncertainty and the fear of COVID-19 in patients awaiting kidney transplantation during the pandemic

Objective:This study aims to identify the relationship between the intolerance of uncertainty and the fear of COVID-19 in patients awaiting kidney transplantation during the COVID-19 pandemic.Methods:This descriptive and cross-sectional study was performed with the participation of 355 individuals.The data were collected with a patient information form,the intolerance of uncertainty scale–short form(IUS),and the fear of COVID-19 scale(FCV-19S).Results:The mean IUS–short form score of the participants was 53.03±5.11,and their mean FCV-19S score was 30.62±4.10.A statistically highly significant positive relationship was identified between the FCV-19S and IUS scores of the participants(r:0.850;P<0.001).Conclusion:As the patients’intolerance of uncertainty increased,their fears of COVID-19 also increased.For patients awaiting kidney transplantation during the COVID-19 pandemic,which is full of challenges,to cope with fear and uncertainty,it is recommended that patients are provided with care with a multidisciplinary team approach.
