Methods: Gene microarray data were downloaded from the Gene Expression Profiling Integrated Database (GEO) and cross-calculated to identify differentially expressed genes (DEGs). Analysis of differentially expressed genes (DEGs) with gene ontology (GO) is a method used to study the differences in gene expression under different conditions as well as their functions and interrelationships, while Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis is a tool used to explore the functions and pathways of genes in specific biological processes. By calculating the distribution of immune cell infiltration, the result of immune infiltration in the rejection group can be analysed as a trait in Weighted Gene Co-Expression Network Analysis (WGCNA) for genes associated with rejection. Then, protein-protein interaction networks (PPI) were constructed using the STRING database and Cytoscape software to identify hub gene markers. Results: A total of 60 integrated DEGs were obtained from 3 datasets (GSE7392, GSE181757, GSE222889). By GO and KEGG analysis, the GEDs were mainly concentrated in the regulation of immune response, defence response, regulation of immune system processes, and stimulation response. The pathways were mainly enriched in antigen processing and presentation, EBV infection, graft-versus-host, allograft rejection, and natural killer cell-mediated cytotoxicity. After further screening using WGCNA and PPI networks, HLA-A, HLA-B, HLA-F, and TYROBP were identified as hub genes (Hub genes). The data GSE21374 with clinical information was selected to construct the diagnostic efficacy and risk prediction model plots of the four hub genes, and the results concluded that all four Hub genes had good diagnostic value (area under the curve in the range of 0.794-0.819). From the inference, it can be concluded that the four genes, HLA-A, HLA-B, HLA-F and TYROBP, may have an important role in the development and progression of chronic rejection after renal transplantation. Conclusion: DEGs play an important role in the study of the pathogenesis of chronic rejection after renal transplantation, and can provide theoretical support for further research on the pathogenesis of chronic rejection after renal transplantation and the discovery of new therapeutic targets through enrichment analysis and pivotal gene screening, as well as inferential analyses of related diagnostic efficacy and disease risk prediction.展开更多

The complications may result from the bone condition prior to transplantation or the iatrogenic effects of the treatments administered. These complications lead to significant morbidity and mortality, in addition to chronic pain and functional impairment. We report the clinical case of bilateral avascular necrosis (AVN) of the femoral head in a kidney transplant recipient. Clinical Case: 53-year-old male with a history of chronic hypertension. He underwent chronic hemodialysis for 12 months and was treated with Entecavir for chronic hepatitis B. The patient received a kidney transplant from a non-related living donor. Induction therapy included Thymoglobulin along with tapered corticosteroids, reaching a dose of 5 mg/day after 3 months, Mycophenolate mofetil (2 g/day), and Tacrolimus adjusted based on residual levels. There was good recovery of renal graft function. After six months, the patient reported bilateral hip pain and functional impairment of both lower limbs. Pelvic X-rays showed signs suggestive of bilateral AVN of the femoral heads. The diagnosis was confirmed by MRI. The patient underwent right hip drilling and total left hip replacement (THR). A right THR was performed a year later. Conclusion: AVN constitutes a frequent cause of morbidity and mortality after RT. The pathophysiology of osteonecrosis remains complex and multifactorial. We emphasize the importance of conducting a thorough assessment of bone health in patients both before and after RT.展开更多

Glioblastoma is the most frequent brain tumor in adults aged 45 - 70 years. It accounts for 12% - 15% of all intracranial tumors. It is characterized by its rapid development and poor prognosis. We report the case of a cerebral glioblastoma in a kidney transplant recipient. Clinical case: Mr G.R, 44 years old caucasian patient who underwent kidney transplantation. Immunosuppressive treatment included cyclosporine, mycophenolate mofetil and methylprednisolone. Creatinine levels after transplantation remained stable at 11 mg/L (96.8 μmol/l) with an estimated glomerular filtration rate (eGFR) of 77 ml/min/1.73m<sup>2</sup> after a 15 years of follow-up. A grade IV right fronto-callossal cerebral glioblastoma was diagnosed in our patient. EBV PCR was negative. Therefore, he underwent 25 sessions of radiotherapy combined with oral chemotherapy using temozolomide. One month later, the patient died due to cerebral edema with subfalcine herniation. Conclusion: This is a case of cerebral glioblastoma in a kidney transplant recipient, a population considered at risk for tumor development due to immunosuppressive treatment. This emphasizes the need for a lifelong surveillance and, more importantly a better balance between graft function preservation and the risks associated with immunosuppressants.展开更多

The skin is the most affected area, but other sites can be involved such as the lung, digestive tract and lymph nodes. The classical presentation involves a violaceous skin lesion that can be small or hidden, leading to a delay in diagnosis. We report a clinical case of a kidney transplant patient, who presented, 14 months after kidney transplant, with unilateral edema of the inferior member and cutaneous rash misdiagnosed and taken initially for erysipelas. The diagnosis of Kaposi’s sarcoma was retained, on a lymph node biopsy of an inguinal adenopathy. The evolution was marked by a local and general improvement after systemic chemotherapy, reducing Tacrolimus and discontinuation of Mycophenolate mofetil. Graft function remained stable during the follow-up.展开更多

Only a few Cases have been described in the literature. The post streptococcal glomerulonephritis is the classic example in native kidney. A wide variety of organism has been associated with PIGN in renal allograft such as Staphylococcus, Cytomegalovirus and Polyomavirus. We describe one case of Infection associated glomerulonephritis due to Echericha Coli, developed 5 years after kidney transplantation, in 47 years old female patient. The Clinical presentation was characterized by a peripheral edema and high blood pressure, and biological tests showed a nephrotic syndrome, an acute kidney injury, a consumption of Complement fractions. The renal biopsy revealed a diffuse endocapillary cell proliferation with preponderant deposits of C3. Total recovery was achieved 4 months after Methyprednisolone pulse and Cyclophasphamid with antimicrobial treatment.展开更多

文摘BACKGROUND Renal cell carcinoma(RCC)is more common in patients with autosomal dominant polycystic kidney disease(ADPKD)than in the general population.Diagnosing RCC in ADPKD is challenging due to the presence of multiple renal cysts,often leading to delays and difficulties in distinguishing RCC from cyst infection or hemorrhage.A total of 38 kidneys were excised from 19 patients,with a mean age of 56.8 years and an average hemodialysis duration of 84.2 months.Eight patients underwent open nephrectomies,and 11 underwent hand-assisted laparoscopic nephrec-tomies.RCC was detected in 15.8%of kidneys,affecting 21.1%of patients.Two patients had multifocal RCC in both kidneys.All RCC cases were pT1 stage,with the largest lesion averaging 16.5 mm in diameter.The average operative duration was 120 minutes,with intraoperative blood loss averaging 184.2 mL.Five patients required blood transfusions.Postoperative complications occurred in five patients,with a mean hospital stay of 17.1 days.The mean follow-up period was 28.1 months.CONCLUSION The prevalence of RCC is higher in patients with ADPKD with ESRD than in those with ESRD alone.Thus,clinicians should be cautious and implement surveillance programs to monitor the development of RCC in patients with ADPKD,particularly those on dialysis.

文摘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.
文摘BACKGROUND Ewing’s sarcoma(ES)is a neuroectodermal tumor that typically occurs in the bones and soft tissues of children and young adults.Primary renal ES is rare;only a few cases and a small case series have been documented,and only four cases involved primary renal ES in older people(>65 years old).CASE SUMMARY Herein,we describe the radiological and pathological features of primary renal ES in an older person.A 76-year-old man complained of poor oral intake and was found to have a large cystic renal mass with indistinct margins on computed tomography.Ultrasound-guided biopsy revealed that the tumor contained small round blue cells.The patient underwent a right radical nephrectomy.The tumor cells showed diffuse membranous CD99,and nuclear friend leukemia integration 1 transcription factor and NK2 Homeobox 2.Fluorescence in situ hybridization revealed EWSR1 translocation.Postoperatively,18F-fluorodeoxyglucose positron emission tomography revealed no evidence of metastasis.The patient was diagnosed with primary renal ES.Six months following the surgery,local recurrence and distant metastasis were observed.Primary renal ES is rare and often lethal in older individuals.The specific imaging findings are unknown,and treatment protocols have not been standardized.CONCLUSION This case report describes the radiological and pathological features of primary renal ES in an older person.

文摘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.

文摘Objective: To use bioinformatics technology to analyse differentially expressed genes in chronic rejection after renal transplantation, we can screen out potential pathogenic targets associated with the development of this disease, providing a theoretical basis for finding new therapeutic targets. Methods: Gene microarray data were downloaded from the Gene Expression Profiling Integrated Database (GEO) and cross-calculated to identify differentially expressed genes (DEGs). Analysis of differentially expressed genes (DEGs) with gene ontology (GO) is a method used to study the differences in gene expression under different conditions as well as their functions and interrelationships, while Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis is a tool used to explore the functions and pathways of genes in specific biological processes. By calculating the distribution of immune cell infiltration, the result of immune infiltration in the rejection group can be analysed as a trait in Weighted Gene Co-Expression Network Analysis (WGCNA) for genes associated with rejection. Then, protein-protein interaction networks (PPI) were constructed using the STRING database and Cytoscape software to identify hub gene markers. Results: A total of 60 integrated DEGs were obtained from 3 datasets (GSE7392, GSE181757, GSE222889). By GO and KEGG analysis, the GEDs were mainly concentrated in the regulation of immune response, defence response, regulation of immune system processes, and stimulation response. The pathways were mainly enriched in antigen processing and presentation, EBV infection, graft-versus-host, allograft rejection, and natural killer cell-mediated cytotoxicity. After further screening using WGCNA and PPI networks, HLA-A, HLA-B, HLA-F, and TYROBP were identified as hub genes (Hub genes). The data GSE21374 with clinical information was selected to construct the diagnostic efficacy and risk prediction model plots of the four hub genes, and the results concluded that all four Hub genes had good diagnostic value (area under the curve in the range of 0.794-0.819). From the inference, it can be concluded that the four genes, HLA-A, HLA-B, HLA-F and TYROBP, may have an important role in the development and progression of chronic rejection after renal transplantation. Conclusion: DEGs play an important role in the study of the pathogenesis of chronic rejection after renal transplantation, and can provide theoretical support for further research on the pathogenesis of chronic rejection after renal transplantation and the discovery of new therapeutic targets through enrichment analysis and pivotal gene screening, as well as inferential analyses of related diagnostic efficacy and disease risk prediction.
文摘BACKGROUND Acute kidney injury(AKI)is a common clinical syndrome with high morbidity and mortality rates.The use of pluripotent stem cells holds great promise for the treatment of AKI.Urine-derived stem cells(USCs)are a novel and versatile cell source in cell-based therapy and regenerative medicine that provide advantages of a noninvasive,simple,and low-cost approach and are induced with high multidifferentiation potential.Whether these cells could serve as a potential stem cell source for the treatment of AKI has not been determined.METHODS Stem cell markers with multidifferentiation potential were isolated from human amniotic fluid.AKI severe combined immune deficiency(SCID)mice models were induced by means of an intramuscular injection with glycerol.USCs isolated from human-voided urine were administered via tail veins.The functional changes in the kidney were assessed by the levels of blood urea nitrogen and serum creatinine.The histologic changes were evaluated by hematoxylin and eosin staining and transferase dUTP nick-end labeling staining.Meanwhile,we compared the regenerative potential of USCs with bone marrow-derived mesenchymal stem cells(MSCs).RESULTS Treatment with USCs significantly alleviated histological destruction and functional decline.The renal function was rapidly restored after intravenous injection of 5×105 human USCs into SCID mice with glycerol-induced AKI compared with injection of saline.Results from secretion assays conducted in vitro demonstrated that both stem cell varieties released a wide array of cytokines and growth factors.This suggests that a mixture of various mediators closely interacts with their biochemical functions.Two types of stem cells showed enhanced tubular cell prolif-eration and decreased tubular cell apoptosis,although USC treatment was not more effective than MSC treatment.We found that USC therapy significantly improved renal function and histological damage,inhibited inflammation and apoptosis processes in the kidney,and promoted tubular epithelial proliferation.CONCLUSION Our study demonstrated the potential of USCs for the treatment of AKI,representing a new clinical therapeutic strategy.
文摘BACKGROUND Acute pancreatitis is a rare extrapulmonary manifestation of coronavirus disease 2019(COVID-19)but its full correlation with COVID-19 infection remains unknown.AIM To identify acute pancreatitis’occurrence,clinical presentation and outcomes in a cohort of kidney transplant recipients with acute COVID-19.METHODS A retrospective observational single-centre cohort study from a transplant centre in Croatia for all adult renal transplant recipients with a functioning kidney allograft between March 2020 and August 2022 to record cases of acute pancreatitis during acute COVID-19.Data were obtained from hospital electronic medical records.Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection was proven by a positive SARS-CoV-2 real-time reverse transcriptase-polymerase chain reaction on the nasopharyngeal swab.RESULTS Four hundred and eight out of 1432(28.49%)patients who received a renal allograft developed COVID-19 disease.The analyzed cohort included 321 patients(57%males).One hundred and fifty patients(46.7%)received at least one dose of the anti-SARS-CoV-2 vaccine before the infection.One hundred twenty-five(39.1%)patients required hospitalization,141(44.1%)developed pneumonia and four patients(1.3%)required mechanical ventilation.Treatment included immunosuppression modification in 233 patients(77.1%)and remdesivir in 53 patients(16.6%),besides the other supportive measures.In the study cohort,only one transplant recipient(0.3%)developed acute pancreatitis during acute COVID-19,presenting with abdominal pain and significantly elevated pancreatic enzymes.She survived without complications with a stable kidney allograft function.CONCLUSION Although rare,acute pancreatitis may complicate the course of acute COVID-19 in kidney transplant recipients.The mechanism of injury to the pancreas and its correlation with the severity of the COVID-19 infection in kidney transplant recipients warrants further research.
文摘BACKGROUND Brachial artery aneurysms are defined as dilations greater than 50%of the normal diameter,which are rare among all peripheral arterial aneurysms.While they are often present as pseudoaneurysms,true brachial artery aneurysms are also detected rarely.In this case report,the surgical repair method of true brachial artery aneurysms,which is a rare condition,is explained.CASE SUMMARY Herein,we present a 61-year-old male patient with complaints of swelling and pain in the right arm antecubital region that had been progressing over 6 mo.Upon the diagnosis of a true brachial artery aneurysm associated with arteriovenous fistula,the aneurysm was surgically repaired with an autologous saphenous vein graft.The patient was discharged without any neurovascular complications postoperatively.CONCLUSION True brachial artery aneurysms are rare and there are not any recommendations for their management in the current literature.Even though the treatment of true aneurysms in this artery is primarily based on a surgical treatment,endovascular repair also might be an option.
文摘Osteoarticular complications are common after renal transplantation. The complications may result from the bone condition prior to transplantation or the iatrogenic effects of the treatments administered. These complications lead to significant morbidity and mortality, in addition to chronic pain and functional impairment. We report the clinical case of bilateral avascular necrosis (AVN) of the femoral head in a kidney transplant recipient. Clinical Case: 53-year-old male with a history of chronic hypertension. He underwent chronic hemodialysis for 12 months and was treated with Entecavir for chronic hepatitis B. The patient received a kidney transplant from a non-related living donor. Induction therapy included Thymoglobulin along with tapered corticosteroids, reaching a dose of 5 mg/day after 3 months, Mycophenolate mofetil (2 g/day), and Tacrolimus adjusted based on residual levels. There was good recovery of renal graft function. After six months, the patient reported bilateral hip pain and functional impairment of both lower limbs. Pelvic X-rays showed signs suggestive of bilateral AVN of the femoral heads. The diagnosis was confirmed by MRI. The patient underwent right hip drilling and total left hip replacement (THR). A right THR was performed a year later. Conclusion: AVN constitutes a frequent cause of morbidity and mortality after RT. The pathophysiology of osteonecrosis remains complex and multifactorial. We emphasize the importance of conducting a thorough assessment of bone health in patients both before and after RT.
文摘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.
文摘BACKGROUND Kidney transplantation leads to continuous improvement in the survival rates of kidney transplant recipients(KTRs)and has been established as the treatment of choice for patients with end-stage kidney disease.Health-related quality of life(HRQoL)has become an important outcome measure.It is highly important to develop reliable methods to evaluate HRQoL with disease-specific questionnaires.AIM To translate the disease-specific instrument Kidney Transplant Questionnaire 25(KTQ-25)to the Greek language and perform a cross-cultural adaptation.METHODS The translation and adaptation of the original English version of the KTQ-25 to the Greek language were performed based on the International Quality of Life RESULTS Eighty-four KTRs(59 males;mean age 53.5±10.7 years;mean estimated glomerular filtration rate 47.7±15.1 mL/min/1.73 m2;mean transplant vintage 100.5±83.2 months)completed the Greek version of the KTQ-25 and the 36-item Short-Form Health Survey,and the results were used to evaluate the reliability of the Greek KTQ-25.The Cronbach alpha coefficients for all the KTQ-25 dimensions were satisfactory(physical symptoms=0.639,fatigue=0.856,uncertainty/fear=0.661,appearance=0.593,emotions=0.718,total score=0.708).The statistically significant correlation coefficients among the KTQ-25 dimensions ranged from 0.226 to 0.644.The correlation coeffi-cients of the KTQ-25 dimensions with the SF-36 physical component summary(PCS)ranged from 0.196 to 0.550;the correlation coefficients of the KTQ-25 with the SF-36 mental component summary(MCS)ranged from 0.260 to 0.655;and the correlation coefficients of the KTQ-25 with the total scores with the SF-36 PCS and MCS were 0.455 and 0.613,respectively.CONCLUSION According to the findings,the Greek version of the KTQ-25 is valid and reliable for administration among kidney transplant patients in Greece.
文摘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.
文摘Cancers is a leading cause of mortality among transplant recipients. The most common cancers are skin tumors. Glioblastoma is the most frequent brain tumor in adults aged 45 - 70 years. It accounts for 12% - 15% of all intracranial tumors. It is characterized by its rapid development and poor prognosis. We report the case of a cerebral glioblastoma in a kidney transplant recipient. Clinical case: Mr G.R, 44 years old caucasian patient who underwent kidney transplantation. Immunosuppressive treatment included cyclosporine, mycophenolate mofetil and methylprednisolone. Creatinine levels after transplantation remained stable at 11 mg/L (96.8 μmol/l) with an estimated glomerular filtration rate (eGFR) of 77 ml/min/1.73m<sup>2</sup> after a 15 years of follow-up. A grade IV right fronto-callossal cerebral glioblastoma was diagnosed in our patient. EBV PCR was negative. Therefore, he underwent 25 sessions of radiotherapy combined with oral chemotherapy using temozolomide. One month later, the patient died due to cerebral edema with subfalcine herniation. Conclusion: This is a case of cerebral glioblastoma in a kidney transplant recipient, a population considered at risk for tumor development due to immunosuppressive treatment. This emphasizes the need for a lifelong surveillance and, more importantly a better balance between graft function preservation and the risks associated with immunosuppressants.
文摘Kaposi sarcoma is a neoplasm caused by human herpesvirus 8 (HHV8) that most commonly affects immunosuppressed patients. The skin is the most affected area, but other sites can be involved such as the lung, digestive tract and lymph nodes. The classical presentation involves a violaceous skin lesion that can be small or hidden, leading to a delay in diagnosis. We report a clinical case of a kidney transplant patient, who presented, 14 months after kidney transplant, with unilateral edema of the inferior member and cutaneous rash misdiagnosed and taken initially for erysipelas. The diagnosis of Kaposi’s sarcoma was retained, on a lymph node biopsy of an inguinal adenopathy. The evolution was marked by a local and general improvement after systemic chemotherapy, reducing Tacrolimus and discontinuation of Mycophenolate mofetil. Graft function remained stable during the follow-up.
文摘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.
文摘BACKGROUND Mineral bone disease is associated with chronic kidney disease and persists after kidney transplantation.Immunosuppressive treatment contributes to the patho-genesis of this disease.Bisphosphonate treatments have shown positive but inde-finite results.AIM To evaluate the effectiveness and safety of bisphosphonate treatment on post kidney transplantation bone mineral density(BMD).METHODS We included kidney transplant recipients(KTRs)whose BMD was measured after the operation but before the initiation of treatment and their BMD was measured at least one year later.We also evaluated the BMD of KTRs using two valid mea-surements after transplantation who received no treatment(control group).RESULTS Out of 254 KTRs,62(39 men)were included in the study.Bisphosphonates were initiated in 35 KTRs in total(20 men),1.1±2.4 years after operation and for a period of 3.9±2.3 years while 27(19 men)received no treatment.BMD improved significantly in KTRs who received bisphosphonate treatments(from-2.29±1.07 to-1.66±1.09,P<0.0001).The control group showed a non-significant decrease in BMD after 4.2±1.4 years of follow-up after surgery.Kidney function was not affected by bisphosphonate treatment.In KTRs with established osteoporosis,active treatment had a similar and significant effect on those with osteopenia or normal bone mass.CONCLUSION In this retrospective study of KTRs receiving bisphosphonate treatment,we showed that active treatment is effective in preventing bone loss irrespective of baseline BMD.
文摘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.
文摘Post infectious Glomerulonephritis (PIGN) in renal allograft is a rare entity. Only a few Cases have been described in the literature. The post streptococcal glomerulonephritis is the classic example in native kidney. A wide variety of organism has been associated with PIGN in renal allograft such as Staphylococcus, Cytomegalovirus and Polyomavirus. We describe one case of Infection associated glomerulonephritis due to Echericha Coli, developed 5 years after kidney transplantation, in 47 years old female patient. The Clinical presentation was characterized by a peripheral edema and high blood pressure, and biological tests showed a nephrotic syndrome, an acute kidney injury, a consumption of Complement fractions. The renal biopsy revealed a diffuse endocapillary cell proliferation with preponderant deposits of C3. Total recovery was achieved 4 months after Methyprednisolone pulse and Cyclophasphamid with antimicrobial treatment.
文摘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.
文摘Tuberculosis(TB)is the leading cause of infectious mortality and morbidity in the world,second only to coronavirus disease 2019.Patients with chronic kidney disease and kidney transplant recipients are at a higher risk of developing TB than the general population.Active TB is difficult to diagnose in this population due to close mimics.All transplant candidates should be screened for latent TB infection and given TB prophylaxis.Patients who develop active TB pre-or post-trans-plantation should receive multidrug combination therapy of antitubercular therapy for the recommended duration with optimal dose modification as per glomerular filtration rate.
