Risk factors and prevention of end stage renal disease in uruguay

Uruguay is a developing country with a privileged established program for renal replacement therapy (RRT) for all patients with end stage renal disease (ESRD) since 1981. In December 2004, the RRT prevalence reached 916 patients per million population. The ESRD incidence has not changed significantly in the last eight years, differing with what is observed in other countries. In contrast, the ESRD incidence secondary to diabetic nephropathy has shown a permanent increase. The prevention of chronic kidney disease (CKD) began in 1989 with the Program of Prevention and Treatment of Glomerulonephritis (PPTG), being extended in 2002 to all CKD and canalized through the National Program of Renal Healthcare (NPRH) since 2004. The registry of glomerulonephritis has been demonstrated in recent years: patients are referral to nephrologists earlier, there is an increase of the frequency of patients with "clinical remission," and thus there is a decrease of the frequency of ESRD in the first three months after referral. The NPRH has been developed in a progressive way with the involvement of government authorities and the active participation of the nephrologists. A global prevention program, integrating the prevention of CKD, cardiovascular diseases, hypertension, and diabetes was developed. The first steps of the program have had important achievements: a rational reorientation of nephrologic care in the first level of attention, patient access to renoprotective medications without cost; a registration system of patients, the creation of a formal multidisciplinary team, and the instauration of a continuous medical education program.     

Surgical Interventions for Renal Replacement Therapy from the View of Nephrologists

Summary BACKGROUND: The number of patients with end-stage renal disease (ESRD) is increasing worldwide at a rate of approximately 5 % per year. In Austria, 6049 patients were suffering from ESRD in the year 2001, an annual rate of 1093 patients. Higher age of patients and co-morbidities are forcing nephrologists to find the optimal renal replacement therapy (RRT) and access modality for the individual patient. METHODS: For patients with ESRD needing RRT, both nephrologist and surgeon should be consulted to ensure optimal management and treatment including vascular access surgery. Patients planned for peritoneal dialysis (PD) are treated with the cooperation of a visceral surgeon. A catheter is inserted into the pelvic area to enable solution exchange. In patients who are to undergo hemodialysis (HD), nephrologists have to decide whether the cardiac condition is suitable for surgical access creation such as fistula or graft. Otherwise alternative hemodialysis devices such as a central venous catheter (CVC), or subcutaneously implantable ports (Dialock^®), have to be discussed. Access function is routinely monitored during dialysis treatment, but still remains the weak component of extracorporeal RRT responsible for 40 % of hospitalization of HD patients. RESULTS: At the dialysis unit of the University Hospital of Graz, 107 patients were under RRT (70 HD and 37 PD), and 235 patients were hemodialyzed in private units in Graz in 2001. 81 ESRD patients were newly enrolled in the chronic HD program. 131 HD accesses were created in new HD patients and patients under treatment for chronic HD. 36 patients developed HD access complications and in these patients, 181 surgical and/or radiological interventions were performed. CONCLUSIONS: In 12 % of the HD patients in Graz, access problems occurred. These patients have a high frequency of surgical and radiological interventions. Access monitoring and measurement of recirculation may help to reduce the complication rate by 38 %. Before onset of RRT, patients need special management to ensure the best dialysis modality. ESRD patients who are suffering from cardiac diseases, diabetes mellitus, or bad peripheral vascular status need a multidisciplinary approach with nephrologists, cardiologists, surgeons and radiologists working together to find the optimal access for dialysis treatment.     

Integrated therapies including erythropoietin decrease the incidence of dialysis: lessons from mapping the incidence of end-stage renal disease in Japan.

BACKGROUND: Erythropoietin (EPO) has been reported to slow the decline of renal function in predialysis chronic kidney disease (CKD) patients. On the contrary, in the recent large-scale randomized controlled trial (RCT), CREATE and CHOIR, which aimed to keep a higher haemoglobin (Hb) level than former trials, the renoprotective effect of EPO was not observed. Today, the renoprotective effect of EPO has become controversial. In order to test the hypothesis that the usage of EPO in predialysis CKD patients may ameliorate the progression of renal disease, we conducted a macro-level observational study dealing with all Japanese predialysis CKD patients. METHODS: Annually since 1982, the Japanese Society for Dialysis Therapy reports the number of patients that have entered maintenance dialysis in each prefecture of Japan. Based on the 2002-2004 data, we calculated the annual incidence of end-stage renal disease (ESRD) in each of the 47 prefectures. The annual amounts paid for EPO by each prefecture, presumably corresponding to the amounts used, corrected for the estimated predialysis CKD patients, were calculated. We examined the relationship between the incidence of new dialysis and the usage of EPO in each prefecture. Furthermore, the usage of EPO was compared with that of antihypertensive agents including angiotensin converting enzyme inhibitor (ACE-I), and that of statin. RESULTS: There were prefectural differences in the annual incidence of ESRD from 2002 to 2004. We also found prefectural differences in the usage of EPO for the three consecutive years. The usage of EPO in predialysis patients was negatively correlated with the incidence of ESRD on linear and multiple regression analyses. At the same time, the usage of EPO had strong positive correlations with the usage of antihypertensive agents including ACE-I and with that of statin. CONCLUSION: Our nationwide epidemiologic study revealed that a higher use of EPO was associated with a decreased incidence of new dialysis in daily clinical practice. In addition, there were strong correlations among the usage of EPO, antihypertensive agents and statin. These data are supportive of, but do not prove, the hypothesis that EPO may be renoprotective, when used in combination with other strategies.     

The renal epidemiology and information network (REIN): a new registry for end-stage renal disease in France.

The French Renal Epidemiology and Information Network (REIN) registry began in 2002 to provide a tool for public health decision support, evaluation and research related to renal replacement therapies (RRT) for end-stage renal disease (ESRD). It relies on a network of nephrologists, epidemiologists, patients and public health representatives, coordinated regionally and nationally. Continuous registration covers all dialysis and transplanted patients. In 2003, 2070 patients started RRT, 7854 were on dialysis and 7294 lived with a functioning graft in seven regions (with a population of 16.5 million people). The overall crude annual incidence rate of RRT for ESRD was 123 per million population (p.m.p.) with significant differences in age-adjusted rates across regions, from 84 [95% confidence interval (CI): 74-94] to 155 [138-172] p.m.p. The principal causes of ESRD were hypertension (21%) and diabetic (20%) nephropathies. Initial treatment for ESRD was peritoneal dialysis for 15% of patients and a pre-emptive graft for 3%. The one-year survival rate was 81% [79-83] in the cohort of 2002-2003 incident patients. As of December 31, 2003, the overall crude prevalence was 898 [884-913] p.m.p, with 5% of patients receiving peritoneal dialysis, 47% on haemodialysis and 48% with a functioning graft. The experience in these seven regions over these two years clearly shows the feasibility of the REIN registry, which is progressively expanding to cover the entire country.     

The epidemiology of end-stage renal disease in Nigeria: the way forward

The incidence of CKD (Chronic kidney disease) in Nigeria has been shown by various studies to range between 1.6 and 12.4%. We have shown that the burden of renal disease in Nigeria is probably significantly higher than any previous study on end-stage renal disease (ESRD) has documented, as most studies are hospital-based and fail to include the many patients who do not have access to hospital care. The increased prevalence of ESRD among blacks in the United States and South Africa compared with other races also suggests that ESRD may be more prevalent in Africa than in the United States and other developed nations. Common causes of CKD in Nigerian adults are glomerulonephritis and hypertension, while common causes in children are glomerulonephritis and posterior urethral valves. In the United States, diabetes and hypertension are the commonest causes of CKD and glomerulonephritis plays a less important role. Access to renal replacement therapy (RRT) in Nigeria is limited, and mortality rates are very high, ranging between 40 and 50%. Important steps towards improving the situation are the development of prevention programmes and increased funding to ensure increased availability of RRT. To achieve this, health policies concerning CKD must be formulated, and the lack of a renal registry makes it difficult for this to be done. There is need for the development of a functional organizational structure for the reporting of CKD in Nigeria, the Nigerian Renal Registry.     

The impact of severe acute kidney injury requiring renal replacement therapy on survival and renal function of heart transplant recipients – a UK cohort study

Severe acute kidney injury (AKI), defined as requiring renal replacement therapy (RRT), is associated with higher mortality postheart transplantation, but its long-term renal consequences are not known. Anonymized data of 3365 patients, who underwent heart transplantation between 1995 and 2017, were retrieved from the UK Transplant Registry. Multivariable binary logistic regression was performed to identify risk factors for severe AKI requiring RRT, Kaplan–Meier analysis to compare survival and renal function deterioration of the RRT and non-RRT groups, and multivariable Cox regression model to identify predicting factors of mortality and end-stage renal disease (ESRD). 26.0% of heart recipients received RRT post-transplant. The RRT group has lower survival rates at all time points, especially in the immediate post-transplant period. However, conditional on 3 months survival, older age, diabetes and coronary heart disease, but not post-transplant RRT, were the risk factors for long-term survival. The predicting factors for ESRD were insulin-dependent diabetes, renal function at transplantation, eGFR decline in the first 3 months post-transplant, post-transplant severe AKI and transplantation era. Severe AKI requiring RRT post-transplant is associated with worse short-term survival, but has no impact on long-term mortality. It also accelerates recipients’ renal function deterioration in the long term.     

Understanding the role of genetic polymorphisms in chronic kidney disease

Although no valid studies clearly indicate increasing or decreasing numbers of incident paediatric patients, the prevalence of chronic kidney disease (CKD) and end-stage renal disease (ESRD) is growing worldwide. This is mainly due to improved access to renal replacement therapy (RRT), increased survival after dialysis and kidney transplantation and an increase in diagnosis and referral of these patients. Although the increase in CKD prevalence is mainly caused by environmental factors, genetic factors may also influence the incidence and/or the progression of CKD and its complications. As CKD patients might be more sensitive to genetic effects due to the exposure to a uraemic milieu, this makes studies of genetic factors especially interesting in this population. The goal of identifying genetic factors that contribute to the outcome of CKD is to gain further understanding of the disease pathogenesis and underlying causes and, possibly, to use this knowledge to predict disease or its complications and to identify a risk population. Therefore, genetic screening of paediatric CKD patients may enhance the impact of preventive measures that could have a positive effect on outcome. Furthermore, by identifying patients’ genetic backgrounds, it is possible that a more individualised therapy could be designed.     

End-Stage Renal Failure and National Resources: The Brazilian Experience

Brazil is the fifth largest and the fifth most populous nation in the world. Its economy rivals Mexico as the strongest in Latin America and ranks among the 15 largest economies in the world. Despite these achievements, a substantial fraction of the Brazilian population still lives in poverty, and many still have limited access to medical assistance. There are currently about 380 patients on hemodialysis per million populations (pmp), approximately one third of the U.S. prevalence, suggesting that a large fraction of end-stage renal disease (ESRD) patients are not diagnosed and treated properly. In Brazil, access to renal replacement therapy (RRT), including renal transplantation, is universal, and the corresponding costs, including those of medications (immunosuppressors and treatment of ESRD complications), are covered by the Brazilian government. However, given the continuous growth of the ESRD population and of the costs incurred by RRT, the efficacy and reach of this system may be severely limited in years to come. In the current struggle against the ESRD epidemics, the Brazilian medical community and health authorities face a triple challenge: to limit the incidence of renal disease, slow or detain the progression of established chronic nephropathies, and ensure that access to quality RRT remains granted to all those who, despite all efforts, reach ESRD.     

Relationships of race and ethnicity to progression of kidney dysfunction and clinical outcomes in patients with chronic kidney failure

In the United States, the incidence of end-stage renal disease (ESRD) is much higher for blacks, Native Americans, and Asians than for whites. The incidence of kidney disease is also higher for populations of Hispanic ethnicity. ESRD attributed to diabetes (ESRD-DM), hypertension (ESRD-HT), and glomerulonephritis (ESRD-GN), in this order of frequency, are the major categories of ESRD in the United States for all race/ethnic groups. By using the incidence rates of ESRD, during the period from 1997 through 2000, and with whites as reference, the highest rate ratio (RR) was observed for ESRD-HT in blacks (RR = 5.96), ESRD-DM in Native Americans (RR = 5.11), and ESRD-GN in Asians (RR=2.20). The data suggest that the excess of ESRD observed for racial/ethnic minorities may be reduced by interventions aimed at prevention/control of hypertension and diabetes. The data suggest that before developing ESRD, patients with chronic renal failure from minority groups have to face more barriers to receive high-quality health care. This may explain why they see nephrologists later and are less likely to receive renal transplantation at initiation of renal replacement therapy (RRT). Improvements in quality of care after initiating RRT may explain the lower mortality and higher scores in heath-related quality of life observed for patients from racial/ethnic minorities.     

Dialysis in Israel, 1989-2005--time trends and international comparisons.

BACKGROUND: A universal increase in the incidence of renal replacement therapy (RRT) was reported in developed countries during the 1990s, especially among the elderly and diabetic patients. We studied trends in RRT incidence and mortality in Israel between 1989 and 2001-2005. METHODS: The end-stage renal disease (ESRD) registry holds data on all RRT patients in Israel. Age-adjusted incidence rate ratios (RRs) were estimated comparing 2001-2005 with 1989. We compared incidence data between Israel and elsewhere using standardized incidence ratios (SIRs). Survival analysis was conducted by the Kaplan-Meier method and Cox's proportional hazards regression was used to compare survival of diabetic with non-diabetic ESRD patients. RESULTS: The mean incidence rates per million population increased from 99 in 1989-1991 to 179 in 2003-2005. In 2000, Israel was the second leading country for incidence of RRT. Age-adjusted incidence rates increased by 67% [95% confidence interval (CI): 49-87%], from 1989 to 2001, but the trend was attenuated between 2002 and 2005. The increase in incidence was positively associated with age, the largest increase being among the elderly aged > or = 75 years (RR: 3.18, 95%CI: 2.72-3.70). Diabetes accounted for 41% of RRT in 2001 vs only 19% in 1989. There was no increase in 1-year survival between the beginning and the end of the study period. Patients with diabetes-associated RRT had 57% increased risk of 1-year mortality (adjusted HR: 1.57 95% CI: 1.51-1.63). CONCLUSIONS: Despite a similar proportion of RRT attributed to diabetes in Israel and other countries, the age-adjusted incidence in Israel is considerably higher than most countries.     

Chronic kidney disease in children: the global perspective

In contrast to the increasing availability of information pertaining to the care of children with chronic kidney disease (CKD) from large-scale observational and interventional studies, epidemiological information on the incidence and prevalence of pediatric CKD is currently limited, imprecise, and flawed by methodological differences between the various data sources. There are distinct geographic differences in the reported causes of CKD in children, in part due to environmental, racial, genetic, and cultural (consanguinity) differences. However, a substantial percentage of children develop CKD early in life, with congenital renal disorders such as obstructive uropathy and aplasia/hypoplasia/dysplasia being responsible for almost one half of all cases. The most favored end-stage renal disease (ESRD) treatment modality in children is renal transplantation, but a lack of health care resources and high patient mortality in the developing world limits the global provision of renal replacement therapy (RRT) and influences patient prevalence. Additional efforts to define the epidemiology of pediatric CKD worldwide are necessary if a better understanding of the full extent of the problem, areas for study, and the potential impact of intervention is desired.     

How Do Living Kidney Donors Develop End‐Stage Renal Disease?

The clinical course and risk factors for developing end-stage renal disease (ESRD) after heminephrectomy in living kidney donors have scarcely been investigated. We reviewed medical records and identified eight case donors who developed chronic kidney disease (CKD) stage 5 or ESRD, and subsequently investigated the association between postoperative clinical courses and changes in renal function. To conduct a case-control study, we also selected a control group comprising 24 donors who had maintained stable renal function and were matched for age, sex and follow-up time since donation. Except for one donor who developed ESRD caused by a traffic accident, none of the donors developed progressive renal dysfunction immediately after donation. Their renal functions remained stable for a long period of time, but started to decline after developing new comorbidities, especially risk factors known as progression factors (proteinuria or hypertension) or accelerating factors (cardiovascular [CV] event or infection) of CKD. As compared with the control donors, incidence of postoperative persistent proteinuria, acute CV event, severe infection and hospitalization due to accelerating factors of CKD were significantly higher in the case donors. These results suggest the importance of long-term (more than 10 years) follow-up of donors with special attention on the risk factors of CKD.     

An expanded nationwide view of chronic kidney disease in Aboriginal Australians

We summarize new knowledge that has accrued in recent years on chronic kidney disease (CKD) in Indigenous Australians. CKD refers to all stages of preterminal kidney disease, including end‐stage kidney failure (ESKF), whether or not a person receives renal replacement therapy (RRT). Recently recorded rates of ESKF, RRT, non‐dialysis CKD hospitalizations and CKD attributed deaths were, respectively, more than sixfold, eightfold, eightfold and threefold those of non‐Indigenous Australians, with age adjustment, although all except the RRT rates are still under‐enumerated. However, the nationwide average Indigenous incidence rate of RRT appears to have stabilized. The median age of Indigenous people with ESKF was about 30 years less than for non‐Indigenous people, and 84% of them received RTT, while only half of non‐Indigenous people with ESKF did so. The first‐ever (2012) nationwide health survey data showed elevated levels of CKD markers in Indigenous people at the community level. For all CKD parameters, rates among Indigenous people themselves were strikingly correlated with increasing remoteness of residence and socio‐economic disadvantage, and there was a female predominance in remote areas. The burden of renal disease in Australian Indigenous people is seriously understated by Global Burden of Disease Mortality methodology, because it employs underlying cause of death only, and because deaths of people on RRT are frequently attributed to non‐renal causes. These data give a much expanded view of CKD in Aboriginal people. Methodologic approaches must be remedied for a full appreciation of the burden, costs and outcomes of the disease, to direct appropriate policy development.     

ESRD in Guatemala and a Model for Preventive Strategies: Outlook of the Guatemalan Foundation for Children with Kidney Diseases

The rapidly growing burden of chronic renal failure (CRF) is a major public health problem that will stretch the health care system of all countries, especially those that are not yet industrialized. It is estimated that only 35% of Guatemalan patients with end stage renal disease (ESRD) would be diagnosed and treated, and unlike many developed countries, the age of presentation in 60% of the patients is before the forth decade. Therefore, the cost of death and disability due to a CRF in this young population is particularly profound, resulting in reduced productivity and economic growth of the country. It is also estimated that 400 pediatric cases develop progressive kidney disorder (neurogenic bladder, reflux nephropathy, chronic glomerulonephritis) annually, which, if left untreated, could result in ESRD in adulthood. This reality justifies initiatives such as FUNDANIER (Foundation for Children with Kidney Diseases), whose mission is to offer comprehensive nephrological treatment to children and adolescents and enable health care providers to prevent ESRD by early identification, diagnosis, and timely referral of children with risk factors. Efforts should be taken to better involve pediatricians and pediatric nephrologists in the fight against the burden of CRF.     

Outcome of renal replacement therapy in the very elderly.

BACKGROUND: In a retrospective case-note and computer database analysis we assessed the outcome of very elderly patients (> or = 75 years old) with end-stage renal disease (ESRD) on renal replacement therapy (RRT). METHODS: Fifty-eight individuals aged 75 or over (group 1) commenced RRT between 1 January 1991 and 31 December 1995. Comparisons were made with other patients commencing RRT who were divided into two groups: group 2 (201 individuals 65-74 years old) and group 3 (379 patients <65 years old). All subjects were followed up until the point of assessment (30 June 1998), the time of death, or withdrawal from dialysis. Survival rates in the three groups were compared using Kaplan-Meier method. The number of hospital admissions, length of in-patient stay, and complications rate on RRT were assessed for group 1. RESULTS: One-year survival rates in groups 1, 2 and 3 were 53.5, 72.6, and 90.6% respectively and the 5-year survival rates were 2.4, 18.8, and 61.4% respectively. The very elderly spent 20% of their time in hospital, 46% had two co-morbid factors at the outset, and 26% developed multiple complications while on RRT. Withdrawal from dialysis remained the most common cause of death in this group of individuals (38%), followed by cardiovascular causes (24%) and infections (22%). CONCLUSION: Very elderly ESRD patients on RRT have a very poor outcome and, since they are the largest growing group of RRT patients, this has important implications for future health policies.     

Referral and comanagement of the patient with CKD

CKD is a common condition with well-documented associated morbidity and mortality. Given the substantial disease burden of CKD and the cost of ESRD, interventions to delay progression and decrease comorbidity remain an important part of CKD care. Early referral to nephrologists has been shown to delay progression of CKD. Conversely, late referral has been associated with increased hospitalizations, higher mortality, and worsened secondary outcomes. Late referral to nephrology has been consequent to numerous factors, including the health care system, provider issues, and patient related factors. In addition to timely referral to nephrologists, the optimal modality to provide care for CKD patients has also been evaluated. Multidisciplinary clinics have shown significant improvements in other disease states. Data for the use of these clinics have shown benefit in mortality, progression, and laboratory markers of disease severity. However, studies supporting the use of multidisciplinary clinics in CKD have been mixed. Evidence-based guidelines from groups, including Renal Physicians Association and NKF, provide tools for management of CKD patients by both generalists and nephrologists. Through the use of guidelines, timely referral, and a multidisciplinary approach to care, the ability to provide effective and efficient care for CKD patients can be improved. We present a model to guide a multidisciplinary comanagement approach to providing care to patients with CKD.     

Current incidence, treatment patterns and outcome of end-stage renal disease among indigenous groups in Australia and New Zealand

SUMMARY: The changes in rates of treated end-stage renal disease (ESRD) among indigenous populations have profound consequences for those individuals affected and for health-care providers. By using data from the Australia and New Zealand Dialysis and Transplant (ANZDATA) Registry, we examined the current incidence, treatment and outcomes of ESRD among indigenous groups in Australia and New Zealand. All patients who began renal replacement therapy (RRT) in Australia or New Zealand between October 1991 and September 2000 were included. Rates of ESRD, RRT modalities, renal transplantation and mortality were the outcomes examined. End-stage renal disease rates among indigenous groups in Australia and New Zealand exceeded non-indigenous rates up to eightfold. The median age of indigenous ESRD patients was younger (51 vs 60 years, P  < 0.0001), and there was an excess of comorbidities, particularly diabetes. For Australian Aboriginal and Torres Strait Islanders, and New Zealand Maori patients, mortality rates across all modalities of RRT were 70% higher than non-indigenous rates. Indigenous people were less likely to receive a renal transplant prior to dialysis treatment, less likely to be accepted onto the cadaveric transplant waiting list, and less likely to receive a well-matched transplant. The poorer outcomes among Australian Aboriginal and Torres Strait Islanders, and New Zealand Maori patients did not appear to be explained by the different comorbid conditions or age. Whether the outcomes reflect unmeasured differences in disease burden or treatment differences is not known. Tackling this problem will involve a spectrum of people and approaches, from tertiary care providers and RRT to local staff and preventative programs.     

Etiology and epidemiology of end-stage renal disease in Dutch children 1987–2001

In this retrospective study 351 children (<16.0 years) with end-stage renal disease (ESRD) accepted for renal replacement therapy (RRT) in the four Dutch pediatric centers were analyzed for the period 1987–2001. The data were compared with a previous study performed in 1979–1986. Eighty patients were of non-Dutch origin. An annual ESRD incidence of 5.8 patients per million of the child population (p.m.c.p.) was calculated, without significant changes with time. The final prevalence in Dutch children under 15 years of ESRD was 38.7 p.m.c.p. The most frequent primary renal disease leading to ESRD was urethral valves, with a significant increase vs. the previous observation period (14% vs. 6%). The distribution of primary renal diseases was similar in patients of non-Dutch origin and in Dutch patients. Peritoneal dialysis was the most frequent dialysis procedure initially applied (62% vs. 26% in the earlier observation period). Thirteen percent of all first transplantations (n=278) were pre-emptive and 19% from living donors. Five-year graft survival after a living-donor and a cadaver graft was 80% and 73%, respectively. Overall patient survival after 10 years on RRT was 94%.     

Syndrome of rapid-onset end-stage renal disease: a new unrecognized pattern of CKD progression to ESRD

By most estimates, we have an increasing worldwide end-stage renal disease (ESRD) epidemic. This is despite at least two decades of intensified reno-protection strategies, including attempts at optimal hypertension management, optimization of diabetic control, smoking cessation efforts, and the extensive application of renin–angiotensin–aldosterone system (RAAS) blockade in both diabetic and nondiabetic chronic nephropathies. The current consensus is that chronic kidney disease (CKD) progression to ESRD is a continuous, progressive, and predictable loss of estimated glomerular filtration rate (eGFR) in CKD patients, inexorably leading to ESRD. Our recent experience in a Mayo Health System Hypertension Clinic, as well as new reports associating ESRD development in CKD patients with episodes of acute kidney injury (AKI), led us to hypothesize that CKD to ESRD progression may not be that predictable, after all. Among a 100 high-risk CKD patient cohort that we have followed up prospectively since 2002, we demonstrated that in 15 of 17 (88%) patients who progressed to ESRD, progression from CKD to ESRD was unpredictable, nonlinear, abrupt, and rapid, and this followed AKI secondary to medical and surgical events. We have coined a new term, the syndrome of rapid-onset end-stage renal disease (SORO-ESRD), to represent this unrecognized syndrome. Larger studies are warranted to confirm our single-center findings. If confirmed to represent a significant proportion of the ESRD population, at least here in the United States, this finding will demand major paradigm shifts in the current concepts of reno-protection and “A-V Fistula first” programs.
