KIDNEY TRANSPLANTATION _____ Table of Contents Page 1 PRE-TRANSPLANT. We believe that it is ethically justifiable to ask renal transplant recipients to undergo protocol biopsies in clinical trials and routine care. Many people feel back to normal after a transplant, once the operation and frequent clinic visits of the first three months are over. Transplant Proc 2001; 33 ( 7–8): 3357. Furness, Peter N.1 10; Philpott, Carl M.2; Chorbadjian, Mary T.2; Nicholson, Michael L.2; Bosmans, Jean-Louis3; Corthouts, Bob L.4; Bogers, Johannes J. P. M.5; Schwarz, Anke6; Gwinner, Wilfried6; Haller, Hermann6; Mengel, Michael7; Seron, Daniel8; Moreso, Francesc8; Cañas, Conception9. Kidney function. reported, when established grafts fail, a detectable impairment of function usually occurs late (2). Clinical trials to improve the long-term outcome in renal transplantation are troubled by the very success of the procedure. This was the most serious single complication in the series and therefore deserves detailed description. When you have two kidneys, we usually take a biopsy from the one on the right hand side. Transpl Int 2000; 13 (Suppl 1): S52. Sub-clinical acute rejection detected using protocol biopsies in patients with delayed graft function. The kidney is scanned with an ultrasound machine and local anaesthetic is given at the site of the biopsy to make the skin on the front of your tummy numb. Discussion. There was no consensus on how this should be managed or whether (as Rush et al. A pathologist—a doctor who specializes in diagnosing diseases—examines the kidney tissue sample in a lab. Most cases of rejection are mild and can be treated with steroid injections and an increase in the amount or type of immunosuppression you take. In the meantime, we believe the evidence is sufficient to justify the introduction of renal transplant protocol biopsies into any new clinical trial that addresses long-term renal allograft survival. Most kidney biopsies do not have any complications but there is a small risk (about 2 - 5%) of bleeding. 30 mins. … 8. e greater than or equal to 1.5 mg/dL or new proteinuria on dipstick urinalysis. Three further patients required transfusion. Despite this medication, about 20% of patients will reject their kidney within the first year, although this may be higher if you have a blood group or antibody incompatible transplant. Protocol biopsies, taken during periods of stable graft function, are vital and may constitute the best strategy to design trials aimed at modifying the natural history of chronic allograft nephropathy with a reasonable number of patients. 8 Conversely, in other fields of organ transplant aside from the kidney, it was reported that 7–23% of cases progressed to ESRD caused by CNI nephrotoxicity within 5 years after organ transplantation. Later episodes of acute rejection might be a better marker, were it not for their rarity, which again means that an adequately powered trial would need unattainable numbers of patients. Chronic allograft nephropathy is the main cause of graft failure and can be detected on biopsy long before graft dysfunction becomes evident (6). This helps us to find out if there is ongoing damage to the kidney (sub-clinical rejection) and will guide us to alter the immunosuppressive medications. This website uses cookies.

Kidney diseases usually affect both kidneys so you will only need a biopsy from one. 1 Clinical Sciences Laboratories, Leicester General Hospital, Leicester, United Kingdom. An on-call interventional radiology service has now been restored. Furthermore, when a protocol biopsy revealed severe fibrosis, there was a tendency to attempt to reduce or even eliminate calcineurin inhibitors from the immunosuppressive regime. Wolters Kluwer Health, Inc. and/or its subsidiaries. The item(s) has been successfully added to ", This article has been saved into your User Account, in the Favorites area, under the new folder. Informed consent was a requirement in every center. Why do I need a kidney biopsy? to maintaining your privacy and will not share your personal information without Another doctor will look at the kidney tissue with a microscope to check for problems. Biopsy of the transplanted kidney taken during the transplant operation is termed implantation transplant biopsy or post-perfusion transplant biopsy depending on the timing of the biopsy with respect to key stages of the operation. 14. We will give you medication (immunosuppression) to stop you rejecting your kidney. have suggested) treatment was required (7), but all centers believed that subclinical acute rejection deserved at least review, and in many cases some modification of the immunosuppressive regime was instituted. The magnitude of any potential benefit for the individual patient remains a matter for debate. The exact position of the kidney is confirmed using an ultrasound scan, which also identifies the best place to take the biopsy. Predefined contraindications varied considerably between institutions, with systemic anticoagulation being the only unanimous exclusion criterion. In Leicester, for logistic reasons, the study was split into two parts. J Am Soc Nephrol 1999; 10 ( 1): 167. 1. The size of needle used varied between 14G and 18G, without detectable variation in the incidence of complications, as has been reported (8). There are some problems with the reproducibility of subjective biopsy interpretation (4), but we recently demonstrated that the introduction of morphometric measurements can produce a dramatic decrease in the number of cases required to produce an adequately powered study, especially if two biopsies are available to allow the assessment of changes over time (5). Kidney transplantation is a life-extending procedure. The most common complication of the procedure is related to bleeding. In addition, GFR was measured at 1 year as 99mTc-DPTA clearance . The benefits of doing a biopsy are always considered carefully for each individual patient and serious complications are extremely rare.The main risk is that your transplant kidney might bleed after the biopsy. 4 : 1.1 Patient Referral 4 ... transplantation in order to improve life expectancy after transplantation. As Kasiske et al. Specific reasons to do a kidney biopsy include: Blood in the urine (hematuria) or protein in the urine (proteinuria) Abnormal blood test results; Acute or chronic kidney disease with no clear cause; Nephrotic syndrome … The most likely outcome will be that no single measurement provides the best possible measure of prognosis; instead, data from several measurements should be integrated with clinical, immunologic, and functional information, perhaps using logistic regression or neural network systems. Immunohistochemistry for PLA2R was negative in all 3 patients. In terms of CNI arteriolopathy, 100% prevalence in 10‐year graft biopsy after transplantation was reported. Call the Transplant office at (212) 305-6469 if you experience any of the following symptoms after your biopsy: Bloody urine Swelling and/or pain near your kidney Major complications were recorded for 2,127 biopsies (Table 3). Abstract. Unfortunately, the original study proposing this benefit was relatively small, and it suffers from the very problem that makes protocol biopsies desirable in clinical trials; data on the “real” outcome measure, graft survival, will take several more years to become available. All rights reserved. This ties in with a local audit of native renal biopsies in Leicester, where postbiopsy hemorrhage requiring nephrectomy was invariably associated with severe parenchymal disease (P. Furness, unpublished data, 1990–2002). Subjective histologic grading systems (3,11) have proven validity and have been widely used, but there are problems with reproducibility between different centers (4). At this point, it was discovered that the hospital management had withdrawn the on-call interventional radiology service without informing the transplant team. Some error has occurred while processing your request. Risks of a renal biopsy Three patients required intervention to control hemorrhage. Kidney Int 1995; 48 (Suppl 52): S120. report the results of a prospective cohort study in 27 kidney graft recipients who consented to a first bone biopsy while still receiving dialysis therapy and a second bone biopsy 2 years after transplantation from deceased donors. Isoniemi H, Taskinen E, Hayry P. Histological chronic allograft damage index accurately predicts chronic renal allograft rejection. In Barcelona, the benefit to the individual patient was unequivocally zero, because the protocol biopsies were assessed independently of the process of patient care, and data were not shared with the clinical team. This is superficially appealing, although applicable only to immunosuppressive drugs. A kidney biopsy is a test to take a sample (biopsy) of kidney. Anal Quant Cytol Histol 1996; 18 ( 5): 410. Many kidney problems can be diagnosed from your symptoms, by examining you, by testing your blood and urine and by X-rays and scans. The surveillance biopsy, also known as the ‘protocol biopsy,’ is defined as the sampling of renal tissue in patients with stable allograft function at predetermined time points [1, 2], typically between 1-12-months post-transplantation.Surveillance biopsies are increasingly used to diagnose subtle (i.e., subclinical) acute and chronic pathology in renal allografts. If the biopsy is of a transplanted kidney, you will be asked to lie on your back and the local anaesthetic is put into the skin over the transplant. Serial protocol biopsies to quantify the progression of chronic transplant nephropathy in stable renal allografts. This approach has been inhibited by concerns over safety, but the risk of biopsy of a stable kidney, with no active inflammation or acute functional impairment, has never been formally estimated. The strictest contraindications were in place in Barcelona: anti-coagulation, bowel interposition, creatinine greater than 300 μmol/L, proteinuria greater than 1 g per day, and unstable renal function. This information leaflet will help you if your doctor advises you . One graft was lost, under circumstances indicating that the loss should have been prevented. Hand and Composite Tissue Transplantation, Belatacept Mediated Costimulation Blockade, TTS Guidelines and Updates from the Vancouver Congress, Humoral Autoimmunity and Transplant Vasculopathy. Biopsies obtained 1 week after transplantation were graded for as and ah, in order to analyse the reproducibility of the vascular scores at baseline (n=43). You should usually not be aware of any pain from the biopsy needle but you may feel a little pressure and hear a clicking sound when the biopsy sample is taken. All registration fields are required. The pathologist looks for signs of kidney disease or infection. The surveillance biopsy is to make sure you do not have rejection that has not been picked up by the blood tests or to see if your kidney is being affected by the medication. A further problem remains in justifying the use of protocol biopsies as a surrogate marker in clinical trials. Audit data on major complications (death, loss of graft, hemorrhage requiring operative intervention, and hemorrhage requiring transfusion) were available for 1,159 biopsies during a continuous 10-year period. All patients underwent percutaneous kidney biopsy.

The problem that we have tried to resolve is the other side of the equation, an accurate estimation of the risk involved. transplanted kidney, if you have had a kidney transplant. Renal transplant patients undergo a biopsy usually at 3 months and 1 year after transplantation. Design of trials of methods to reduce late renal allograft loss: the price of success. When the transplanted kidney is not working properly, biopsy may be undertaken to identify the cause of dysfunction. Jain S, Curwood V, White SA, et al. Consequently, cases of subclinical acute rejection were detected as we have reported elsewhere (9). Less than 1 in 20 transplant patients have an acute rejection episode that leads to complete failure of their new kidney. Despite the large number of biopsy events studied, the low rate of serious complications described does not permit any statistical evaluation of possible associations with different practice in different centers. All serious complications presented within 4 hr of biopsy. Calcium Disorders Hypercalcemia. your express consent. Statistical methods This analysis of registry data convincingly argued that acute rejection was not an adequate surrogate marker for long-term graft survival. Hunsicker LG, Bennett LE. Furness PN, Taub N. International variation in the interpretation of renal transplant biopsies: report of the CERTPAP Project.

In one case, the hemorrhage resulted from the biopsy needle disrupting the patient’s inferior epigastric artery rather than the hemorrhage coming from the graft. Thus, 2,127 biopsy events were studied for less frequent and major complications, and 1,486 biopsies were studied for more frequent and less serious complications. Clinical trials in renal transplantation must use surrogate markers of long-term graft survival if conclusions are to be drawn at acceptable speed and cost. There were no patient deaths attributable to biopsy. Biopsies carry a risk for serious complications and not all biopsies achieve adequate tissue. The sample is examined under a microscope to look at your kidney in greater detail. In addition, your transplant doctor may ask you to have a biopsy at any time to make sure there is no rejection or infection in your kidney. To achieve such large numbers, we undertook an audit of complications of protocol biopsies in four major European transplant centers, which all have a long history of using the procedure. Furness PN. You may be trying to access this site from a secured browser on the server. However, the rate of patient refusals varied considerably between centers (9.8% in Barcelona and 1.6% in Hannover). The lowest dropout rate resulting from contraindications was in Hannover (1.3%). A kidney biopsy is a small operation during which a special needle is used to take a tiny piece (sample) of one of your kidneys (or your kidney transplant) for further examination. Kidney Int Suppl 1995; 52: S116. Introduction: Kidney biopsies are an essential tool in the diagnosis and management of kidney diseases, particularly in kidney transplant recipients. The nursing staff will check your pulse, blood pressure and urine colour and will look at the biopsy site. Transplantation 2000; 69 ( 9): 1849. Measurements of interstitial or vascular fibrosis have been tested (5,12–14), but it has recently been suggested that more “acute” changes such as lymphocytic infiltration might have greater prognostic impact (15). Three episodes of hemorrhage required direct intervention. We know that acute rejection is an adverse prognostic factor for long-term survival. Chronic renal allograft rejection and clinical trial design. Most patients do not need a biopsy of their kidney while they are in hospital but if your kidney does not work straight away or if we suspect you have rejection, we may need to do a biopsy of your transplanted kidney. The most widely used surrogate marker for graft survival is the incidence or severity of episodes of acute rejection. Introduction. 6 Department of Nephrology, Hannover Medical School, Hannover, Germany. Moreso F, Lopez M, Vallejos A, et al. Very rarely (1% of transplants), we cannot stop the kidney rejecting and we have to remove the kidney. Just because you reject your kidney does not necessarily mean that the kidney will fail and most cases of rejection can be stopped with medication. Transplantation 1990; 50 ( 5): 790. These crystals were absent in the initial donor biopsy specimens; von Kossa stain was negative, indicating the absence of phosphate. It is our opinion that the risk of the procedure is sufficiently low to make it legitimate to request a protocol biopsy as part of a clinical trial even if there is an assumption of zero direct benefit to the patient concerned, assuming the patient has given consent on the basis of appropriate information, including a risk assessment. However, controversy exists about the right length of postbiopsy observation. Kidney Int 2001; 60 ( 5): 1998. After the test, you will be told to lie down on your back for several hours. Postbiopsy observation was typically 24 hr, except in Hannover, where the procedure was performed as a day case with a 4-hr observation. This stings a little at first but then makes the skin numb. This patient and one other patient required operative intervention. Accurate quantification of a small risk requires large numbers of patients. Protocol renal allograft biopsies and the design of clinical trials aimed to prevent or treat chronic allograft nephropathy. Transplant kidney biopsy performed 3 weeks after surgery showed normal glomerular, interstitial, and vascular morphologic patterns, but intratubular obstruction by crystals of unknown type. In the other three centers, results from the protocol biopsies were made available as part of clinical management. In every case, the presence of a problem would have been recognized within the shortest period of observation used (4 hr), although, as described, the seriousness of the problem may not have become evident if the patient had not been subjected to 24-hr observation. This aspect of the cost-benefit analysis was not formally evaluated. Other possibilities, such as assessing gene expression or levels of cell senescence (16) have barely been explored. Seron D, Moreso F, Gratin C, et al. All other complications in the audit showed considerable variation in levels of reporting between different hospitals (Table 4). For immediate assistance, contact Customer Service: Local anaesthetic is then injected into a small area of skin and tissues just over the kidney to be sampled (biopsied). If it is confirmed that treatment of “subclinical acute rejection” prolongs long-term graft survival, then one benefit will be clear (7). The nature of the problem demands a multicenter study to provide an answer, and we have acknowledged that this introduces considerable variation in biopsy practice, follow-up, and investigation. CKD-MBD (Chronic kidney disease bone and mineral disorder) – Disease that affects the bones and blood vessels. 7. 10 Address correspondence to: Professor Peter N. Furness, Clinical Sciences Laboratories, Leicester General Hospital, Gwendolen Road, Leicester, LE5 4PW, United Kingdom. You may have had a biopsy of your own kidney. Introduction. After you leave hospital, you will be asked to have a surveillance (protocol) biopsy at three months and twelve months after your transplant. Nevertheless, we believe we can confidently state that the incidence of clinically significant problems is low; the 2,127 biopsy events produced only eight major complications, with only one graft loss and no patient fatalities. 9. Those centers actively undertaking a protocol biopsy program express the view that the risks are small and, even for the individual patient, are outweighed by the potential benefits of detecting unexpected changes, such as donor-related vascular disease, “subclinical” acute rejection, or complications of therapy (7). Data is temporarily unavailable. Morphologic changes in transplant biopsies provide the earliest available evidence of damage, and “protocol” biopsies from stable grafts can be used to reduce the number of patients needed in clinical trials. The questions to be answered in this audit were defined at the outset and are listed in Table 1. Reasons for a kidney biopsy. Renal function was measured as serum creatinine at 1 and 3 years after transplantation. Indeed, it is so low that even with a large multicenter study such as this we have insufficient serious complications to permit any statistical analysis of the circumstances under which they occurred. Registered users can save articles, searches, and manage email alerts. Hematuria was noted soon after the biopsy, but initially its … In practice, the graph of inverse creatinine against time is rarely a straight line for the individual patient, and analysis of registry data confirms that graft function at 1 year is not a reliable predictor of long-term survival (1). 5. This is most clear in the case of arteriovenous fistulae, in which one center followed the biopsy with a Doppler ultrasonography scan, specifically looking for this complication. In this issue of the CJASN, Keronen et al. Please enable scripts and reload this page. Similarly, the benefit of avoiding calcineurin inhibitors selectively in patients whose grafts demonstrate severe interstitial fibrosis or significant intimal fibrosis remains hypothetical without proof from long-term studies. Wolters Kluwer Health In this case, you will return to dialysis and may be considered for another transplant in the future. 9 Radiology Department, Hospital de Bellvitge, L’Hospitalet, Barcelona, Spain. Automated classification of renal interstitium and tubules by local texture analysis and a neural network. Nevertheless, we hope that the data presented here will assist clinicians in deciding whether it is justifiable to request a protocol biopsy and will also assist patients in deciding whether to give consent. Registered users can save articles, searches, and manage email alerts. 12. Consequently, in clinical trials in which protocol biopsies have been planned at the outset, the compliance rate has sometimes been too low to be scientifically useful (P. Halloran, M.D., personal communication, 2001). J Am Soc Nephrol 1998; 9 ( 11): 2129. During the subsequent investigation, it was agreed that the graft could almost certainly have been preserved with better management. Even according to the strictest set of contraindications used by any center in this study, there were no contraindications to the biopsy. 3 Department of Nephrology-Hypertension, University Hospital Antwerpen, Edegem, Belgium. The Banff 97 working classification of renal allograft pathology. The finding of vascular lesions often led to an adjustment of the antihypertensive treatment or lipid-lowering drugs. A biopsy is recommended when blood and urine tests show a . The doctor puts a long needle through your back (flank) into the kidney. After you leave hospital, you will be asked to have a surveillance (protocol) biopsy at three months and twelve months after your transplant. The risk of damaging your transplant is very small and the benefit of knowing what is going on in the kidney often outweighs the small risk to you of undergoing the biopsy. We ask that you take your medication regularly and on time to avoid rejection or other serious consequences. Data on less serious complications were more labor intensive to collect, so this was limited to 518 biopsies during a 4-year period. A prospective randomized trial of three different sizes of core-cutting needle for renal transplant biopsy. The typical patient will live 10 to 15 years longer with a kidney transplant than if kept on dialysis. may email you for journal alerts and information, but is committed You will then be asked to lie on your bed for the next four to six hours while the nurses monitor your blood pressure and pulse. Two patients experienced nonfatal peritonitis after the biopsy. In addition to these patients, three patients required transfusion without further operative intervention. 7 Department of Pathology, Hannover Medical School, Hannover, Germany. Most episodes of rejection are picked up by a change in your kidney function on the blood tests and it is unusual for you to have symptoms of rejection. A total of 2,127 biopsy events were assessed for major complications, and 1,486 were assessed for minor ones. Kidney Int 2000; 58 ( 1): 390. Postbiopsy investigations varied considerably, from observation only in Leicester to postbiopsy computed tomography scan with hemoglobin estimation prebiopsy and 24-hr postbiopsy in Antwerp. 2 Department of Surgery, Leicester General Hospital, Leicester, United Kingdom. biopsy available for each patient and all of those biopsies had IF and EM. There were numerous biopsies not performed for unexplained reasons, so the refusal rate was probably higher. The mean time until biopsy was 4.89 years. Such responses, intended to benefit individual patients, were not formally planned in this retrospective audit, and any resultant benefits were not assessed. Your doctor will discuss the risks and benefits of having the biopsy done at the time. This variation may account for some of the center-specific variation in the rates of less serious complications, as described next. You will be asked to hold your breath for a few seconds as the kidney moves during breathing. Some clinicians believe that renal transplant protocol biopsy poses a significant risk to graft survival, a risk that is greater than the potential benefit for the patient. Halloran PF, Melk A, Barth C. Rethinking chronic allograft nephropathy: the concept of accelerated senescence. However, the risks of renal transplant protocol biopsy have not been quantified. Rejection is a normal response of your body to a foreign kidney. Please try again soon. In Leicester, patient refusal was not always documented. There were no deaths. The anecdotal experience of individual centers indicates that the risk of serious complications from protocol biopsy is low. Beneficial effects of treatment of early subclinical rejection: a randomized study. 5 Department of Pathology, University Hospital Antwerpen, Edegem, Belgium. 6. Kasiske BL, Massy ZA, Guijarro C, et al. Biopsies were taken using a spring-loaded gun under ultrasound guidance in every center except Antwerp, where a Tru-Cut needle was used with computed tomography imaging. Woestenburg AT, Mensch PP, Bosmans JL, et al. The risk of rejection decreases with time and is less likely after the first year. Lippincott Journals Subscribers, use your username or email along with your password to log in. A clinical safety evaluation of 1129 biopsies. 4. One was the direct consequence of the biopsy needle puncturing the caecum. Morphometric analysis of renal vessels. Bone biopsy – Used to diagnose bone disease by taking a small sample of bone from the body and looking at it under a microscope. Although serious bleeding is very rare, we observe you closely for 6 hours after the biopsy. This population-based study included patients who received a deceased donor kidney that had been biopsied before implantation according to a prespecified protocol in France and Belgium, where preimplantation biopsy findings are generally not used for decision making in the allocation process. Please read it and talk to your doctors and nurses. Most grafts last 10 years or more, so the most meaningful outcome measurement—graft survival—cannot be used if results are to be provided in a reasonable time frame, with a practical number of patients and at acceptable cost (1). During a kidney biopsy — also called renal biopsy — your doctor removes a small piece of kidney tissue to examine under a microscope for signs of damage or disease.Your doctor may recommend a kidney biopsy to diagnose a suspected kidney problem, determine the severity of kidney disease or monitor treatment for kidney disease.
