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of the times,long-term graft survival could be inadvertently jeopardized if the immunosuppressive therapy is reduced or withdrawn for any reason,and that it could happen frequently if the transplant physician intends to innovate with the clinical care without proper evidence-based data.

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.

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.

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.

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.

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.

Outcomes of early hospital readmission after kidney transplantation: Perspectives from a Canadian transplant centre

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.

Gastrointestinal manifestations of long-term effects after COVID-19 infection in patients with dialysis or kidney transplantation:An observational cohort study

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.

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.

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.

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.

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.

Mediating role of inner strength in the relationship between medication literacy and medication adherence among kidney transplant patients

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.

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.

Application and management of continuous glucose monitoring in diabetic kidney disease

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.

Pleural empyema with endobronchial mass due to Rhodococcus equi infection after renal transplantation: A case report and review of literature

BACKGROUND Kidney transplantation is the best option for patients with end-stage renal disease.However,the need for lifelong immunosuppression results in renal transplant recipients being susceptible to various infections.Rhodococcus equi(R.equi)is a rare opportunistic pathogen in humans,and there are limited reports of infection with R.equi in post-renal transplant recipients and no uniform standard of treat-ment.This article reports on the diagnosis and treatment of a renal transplant recipient infected with R.equi 21 mo postoperatively and summarizes the charac-teristics of infection with R.equi after renal transplantation,along with a detailed review of the literature.Here,we present the case of a 25-year-old man who was infected with R.equi 21 mo after renal transplantation.Although the clinical features at the time of presentation were not specific,chest computed tomography(CT)showed a large volume of pus in the right thoracic cavity and right middle lung atelectasis,and fiberoptic bronchoscopy showed an endobronchial mass in the right middle and lower lobe orifices.Bacterial culture and metagenomic next-generation sequen-cing sequencing of the pus were suggestive of R.equi infection.The immunosup-pressive drugs were immediately suspended and intravenous vancomycin and azithromycin were administered,along with adequate drainage of the abscess.The endobronchial mass was then resected.After the patient’s clinical symptoms and chest CT presentation resolved,he was switched to intravenous ciprofloxacin and azithromycin,followed by oral ciprofloxacin and azithromycin.The patient was re-hospitalized 2 wk after discharge for recurrence of R.equi infection.He recovered after another round of adequate abscess drainage and intravenous ciprofloxacin and azithromycin.CONCLUSION Infection with R.equi in renal transplant recipients is rare and complex,and the clinical presentation lacks specificity.Elaborate antibiotic therapy is required,and adequate abscess drainage and surgical excision are necessary.Given the recurrent nature of R.equi,patients need to be followed-up closely.
