Thirty-six consecutively transplanted renal allograft patients were prospectively monitored with ultrasound-Doppler examinations three times weekly during the first 3 weeks after transplantation. Although triple-immunosuppressive therapy consisting of cyclosporin A, azathioprine and prednisolone was used, acute rejection occurred in 11 patients. Nine patients had immediate onset of graft function and no rejection. Ten patients had acute tubular necrosis (ATN) without any signs of rejection and were treated with dialysis for 1-3 weeks after transplantation. Thrombosis of the renal artery was diagnosed in four patients. During rejection episodes pulsatility index (PI) was above normal range in all patients. In patients with mild to moderate ATN and PI was normal throughout the clinical course whereas two patients with severe ATN but no signs of rejection in the kidney biopsy also had high PI. It is concluded that serial Doppler velocity examination after kidney transplantation is a non-invasive, cheap and reliable method for monitoring of the graft. The method can be used in the early diagnosis of rejection, and it is of special value in monitoring grafts without function. 相似文献

Renal ischaemia-reperfusion (I/R) injury is a clinically significant problem and an invariable consequence of renal transplantation. The problem begins at the onset of acute tubular necrosis (ATN), when the transplantation takes a long ischaemic interval by using the cardiac arrest donor's kidney. In addition, the longer the ischaemic interval, the higher the incidence rate of ATN. It is clinically important that renal I/R injury is reduced. The antisense oligodeoxynucleotide (AS-ODN), developed as a therapy for intractable diseases at the gene level, has recently been established as an important method in examining specific gene functions. The authors have previously demonstrated that AS-ODN/tissue factor (TF) prevents renal I/R injury. This review discusses the efficacy of AS-ODN/TF and AS-ODN/intercellular adhesion molecule-1 as existing targets, and the potential of AS-ODN/nuclear factor-kappaB, AS-ODN/cyclooxygenase and AS-ODN/5-lipoxygenase as prospective targets. 相似文献

Acute tubular necrosis (ATN) is the most common cause of acute renal failure. Early recognition of patients who are at risk for ATN can prevent or improve the course of ATN. Acute renal failure is classified as prerenal, intrinsic, or postrenal disease. ATN is classified as a type of intrinsic renal disease. The clinical course of ATN is divided into the renal failure phase, diuretic phase, and recovery phase, with each phase having distinct symptoms and laboratory findings. Diagnosis of ATN often is complicated and confusing; understanding of laboratory findings can facilitate the critical care nurse's ability to assess those at risk for ATN. The care and treatment of the patient with ATN is complicated, and specific treatments are discussed in detail. The critical care nurse can play a vital role in identifying the patient at risk, preventing the development of ATN in those at risk, and providing appropriate care for those who develop ATN. 相似文献

When the MAP decreases below approximately 75 mm Hg, renal autoregulatory processes are no longer effective. Decreased renal blood flow often leads to ATN and its related uremic syndrome. The patient with ATN typically experiences four successive phases as the ATN progresses and then eventually resolves. During the oliguricanuric phase of ATN, multiple organ systems and physiologic processes are affected by the alterations occurring as the result of severely altered renal function. With appropriate treatment, such as fluid-electrolyte and acid-base control, nutritional support, and renal replacement therapy, a return to normal renal function is often possible. 相似文献

目的:探讨Clara细胞分泌蛋白(CCSP)检测在诊断急性肾小管坏死(ATN)中的意义,以提高ATN的早期诊断率。方法:选取4例ATN患者肾活检组织,以原发性慢性肾小球肾炎[膜性肾病(MN)/微小病变(MCD)n=4]患者的肾脏及4例正常肾组织作为对照,应用免疫组化和免疫荧光方法检测肾脏组织的CCSP表达。选择10例ATN、10例原发性慢性肾小球炎(MN/MCD)和15例正常对照,采用ELISA法测定其血、尿CC16浓度。结果:免疫组化和免疫荧光结果显示,ATN组、MN/MCD组及正常对照组,肾小球中均无CCSP表达,肾小管上皮细胞有CCSP表达。而其中ATN患者则因肾小管受损,其肾小管上皮细胞CCSP表达较另2组下降。ATN患者起病期与肾功能恢复期间尿CC16差异有统计学意义[(1624.45±1119.11)ng/mL比(472.60±289.36)ng/mL,P〈0.01]。尿CC16浓度在ATN起病期显著增高,与正常对照组、MN/MCD组间差异有统计学意义(P〈0.05)。结论:检测肾组织中CCSP有助于判断患者的肾小管功能.特别是近端肾小管受损情况:尿CC16浓度测定可作为急性肾小管损伤的指标,且与受检者肾组织中CCSP表达相吻合。 相似文献

A porcine model was devised to investigate Doppler waveforms in dysfunctional renal allografts. NIH miniature pigs served as allografts donors and recipients. Renal transplantation was effected into the recipient pelvis while the left normotopic kidney was subjected to warm ischemia in order to induce acute tubular necrosis (ATN). Doppler demonstration of allograft arterial occlusion in six animals was confirmed at surgery. Increased pulsatility of intrarenal arterial signals constituted evidence of vascular rejection in two animals. Biopsies confirmed the diagnosis in both cases. Histologic changes of ATN were identified in two native kidneys subjected to ischemia. No waveform or pulsatility alterations were observed in these animals. The porcine model provides for the investigation of allograft Doppler waveforms in a controlled setting with free access to biopsy and operative pathologic correlation. 相似文献

Acute kidney injury (AKI) is a syndrome that is associated with a major burden of morbidity and mortality in a variety of
high risk patient populations, many of them cared for by intensivists. Following renal transplantation, delayed graft function
(DGF) caused by severe acute tubular necrosis (ATN), defined by a requirement for dialysis during the initial post-transplant
week, complicates postoperative management, and if prolonged (>14 days), adversely affects allograft survival. Neutrophil
gelatinase-associated lipocalin (NGAL) and other novel biomarkers can detect AKI earlier than serum creatinine, and can predict
AKI severity in high risk patient populations, including kidney transplant recipients. Hollmen and colleagues now demonstrate
that elevated urine NGAL in deceased kidney donors is a significant risk factor for prolonged post-transplant DGF in recipients.
These findings have clear implications with regard to potentially improved assessment of deceased donor suitability for potential
renal allograft donation. These findings are also consistent with the growing evidence that severe ATN diagnosed by markedly
elevated levels of AKI biomarkers is a useful predictor of the requirement for acute renal replacement therapy in AKI patients. 相似文献

INTRODUCTION: This study investigated whether serial daily measurements of serum C-reactive protein (sCRP) could help differentiate episodes of transplant dysfunction due to rejection, infection, cyclosporine A (CsA) nephrotoxicity, or acute tubular necrosis (ATN) in renal-allograft recipients. MATERIALS AND METHODS: Morning serum was obtained daily from 134 patients during the first 30 days after renal transplantation. All episodes of graft dysfunction were recorded and differentiated with transplant biopsies. CRP concentrations were correlated with post-operative graft function and the various causes of graft dysfunction. RESULTS: All patients showed an increase in sCRP in response to surgery, with a maximum on day 2 after transplantation. The sCRP concentration was significantly higher in patients with delayed graft function (mean 61.50 microg/ml) than in patients with primary graft function (mean 38.01 microg/ml) (p=0.001). Bacterial infections other than asymptomatic bacteriuria (mean sCRP 33.98 microg/ml), interstitial graft rejection (mean sCRP 16.43 microg/ml), and ATN (mean sCRP 30.50 microg/ml) were accompanied by significant increases in sCRP compared with uneventful courses. sCRP was unchanged in the presence of viral infections or CsA toxicity. CONCLUSION: Serial sCRP measurements help to identify renal-transplant dysfunction of different origins. However, rejection, infection and ATN show similar patterns of sCRP increase. Thus, sCRP is unable to discriminate the causes of renal-graft dysfunction. Biopsy remains the gold standard for the differential diagnosis of renal-allograft dysfunction. 相似文献
