Abstract
BACKGROUND The pre-dialysis care trajectory impact on post-dialysis outcomes is poorly known. This study assessed survival, access to kidney transplant waiting list and to transplantation after dialysis initiation by taking into account the patients' pre-dialysis care consumption (inpatient and outpatient) and the conditions of dialysis start: initiation context (emergency or planned) and vascular access type (catheter or fistula). METHODS Adults who started dialysis in France in 2015 were included. Clinical data came from the French REIN registry and data on the care trajectory from the French National Health Data system (SNDS). The Cox model was used to assess survival and access to kidney transplantation. RESULTS We included 8856 patients with a mean age of 68 years. Survival was shorter in patients with emergency or planned dialysis initiation with a catheter compared to patients with planned dialysis with a fistula. The risk of death was lower in patients who were seen by a nephrologist more than once in the 6 months before dialysis than in those who were seen only once. The rate of kidney transplant at 1 year post-dialysis was lower for patients with emergency or planned dialysis initiation with a catheter (respectively, HR = 0.5 [0.4; 0.8] and HR = 0.7 [0.5; 0.9]) compared to patients with planned dialysis start with a fistula. Patients who were seen by a nephrologist more than three times between 0 and 6 months before dialysis start were more likely to access the waiting list 1 and 3 years after dialysis start (respectively, HR = 1.3 [1.1; 1.5] and HR = 1.2 [1.1; 1.4]). CONCLUSIONS Nephrological follow-up in the year before dialysis initiation is associated with better survival and higher probability of access to kidney transplantation. These results emphasize the importance of early patient referral to nephrologists by general practitioners.

Can J Kidney Health Dis 2019; 6:2054358119831684. [PMID: 30899532 PMCID: PMC6419254 DOI: 10.1177/2054358119831684] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2018] [Accepted: 01/14/2019] [Indexed: 11/16/2022] Open
Abstract
Background: Unplanned dialysis initiation is common in patients with chronic kidney disease (CKD). Objective: To determine common definitions and patient risk factors for unplanned dialysis. Design: Systematic review. Setting: MEDLINE, EMBASE, and the Cochrane Library were searched from inception to February 2018. Patients: Studies that included incident chronic dialysis patients or patients with CKD that cited a definition or examined risk factors for unplanned dialysis were included. Measurements: Definitions and criteria for unplanned dialysis reported across studies. Patient characteristics associated with unplanned dialysis. Methods: Two reviewers independently extracted data using a standardized data abstraction form and assessed study quality using a modified New Castle Ottawa Scale. Results: From 2797 citations, 48 met eligibility criteria. Reported definitions for unplanned dialysis were variable. Most publications cited dialysis initiation under emergency conditions and/or with a central venous catheter. The association of patient characteristics with unplanned dialysis was reported in 26 studies, 18 were retrospective and 21 included incident dialysis patients. The most common risk factors in univariate analyses were (number of studies) increased age (n = 7), cause of kidney disease (n = 6), presence of cardiovascular disease (n = 7), lower serum hemoglobin (n = 9), lower serum albumin (n = 10), higher serum phosphate (n = 6), higher serum creatinine or lower estimated glomerular filtration rate (eGFR) at dialysis initiation (n = 7), late referral (n = 5), lack of dialysis education (n = 6), and lack of follow-up in a predialysis clinic prior to dialysis initiation (n = 5). A minority of studies performed multivariable analyses (n = 10); the most common risk factors were increased age (n = 4), increased comorbidity score (n = 3), late referral (n = 5), and lower eGFR at dialysis initiation (n = 3). Limitations: Comparison of results across studies was limited by inconsistent definitions for unplanned dialysis. High-quality data on patient risk factors for unplanned dialysis are lacking. Conclusions: Well-designed prospective studies to determine modifiable risk factors are needed. The lack of a consensus definition for unplanned dialysis makes research and quality improvement initiatives in this area more challenging.

Abstract
BACKGROUND End-Stage renal disease (ESRD) causes considerable morbidity and mortality, and significantly alters patients' quality of life. There are very few published data on this problem in the French Overseas territories. The development of a registry on end stage renal disease in French Guiana in 2011 allowed to describe the magnitude of this problem in the region for the first time. METHODS Using data from the French Renal Epidemiology and Information Network registry (R.E.I.N). Descriptive statistics on quantitative and qualitative variables in the registry were performed on prevalent cases and incident cases in 2011, 2012 and 2013. RESULTS French Guiana has one of the highest ESRD prevalence and incidence in France. The two main causes of ESRD were hypertensive and diabetic nephropathies. The French Guianese population had a different demographic profile (younger, more women, more migrants) than in mainland France. Most patients had at least one comorbidity, predominantly (95.3%) hypertension. In French Guiana dialysis was initiated in emergency for 71.3% of patients versus 33% in France (p < 0.001). CONCLUSION These first results give important public health information: i) End stage renal disease has a very high prevalence relative to mainland France ii) Patients have a different demographic profile and enter care late in the course of their renal disease. These data are closer to what is observed in the Caribbean or in Latin America than in Mainland France.

Abstract
In 2002, the National Kidney Foundation Kidney Disease Outcomes Quality Initiative (NKF KDOQI) instituted new guidelines that established a novel chronic kidney disease (CKD) staging paradigm. This set of guidelines, since updated, is now very widely accepted around the world. Nevertheless, the authoritative United States Preventative Task Force had in August 2012 acknowledged that we know surprisingly little about whether screening adults with no signs or symptoms of CKD improve health outcomes and that we deserve better information on CKD. More recently, the American Society of Nephrology and the American College of Physicians, two very well respected United States professional physician organizations were strongly at odds coming out with exactly opposite recommendations regarding the need or otherwise for ”CKD screening” among the asymptomatic population. In this review, we revisit the various angles and perspectives of these conflicting arguments, raise unanswered questions regarding the validity and veracity of the NKF KDOQI CKD staging model, and raise even more questions about the soundness of its evidence-base. We show clinical evidence, from a Mayo Clinic Health System Renal Unit in Northwestern Wisconsin, United States, of the pitfalls of the current CKD staging model, show the inexactitude and unpredictable vagaries of current CKD prediction models and call for a more cautious and guarded application of CKD staging paradigms in clinical practice. The impacts of acute kidney injury on CKD initiation and CKD propagation and progression, the effects of such phenomenon as the syndrome of late onset renal failure from angiotensin blockade and the syndrome of rapid onset end stage renal disease on CKD initiation, CKD propagation and CKD progression to end stage renal disease all demand further study and analysis. Yet more research on CKD staging, CKD prognostication and CKD predictions is warranted. Finally and most importantly, cognizant of the very serious limitations and drawbacks of the NKF K/DOQI CKD staging model, the need to individualize CKD care, both in terms of patient care and prognostication, cannot be overemphasized.

Abstract
BACKGROUND Early referral of patients with chronic kidney disease (CKD) is believed to help with interventions to address risk factors to slow down the rate of progression of kidney failure to end-stage kidney disease (ESKD) and the need for dialysis, hospitalisation and mortality. OBJECTIVES We sought to evaluate the benefits (reduced hospitalisation and mortality; increased quality of life) and harms (increased hospitalisations and mortality, decreased quality of life) of early versus late referral to specialist nephrology services in CKD patients who are progressing to ESKD and RRT. In this review, referral is defined as the time period between first nephrology evaluation and initiation of dialysis; early referral is more than one to six months, whereas late referral is less than one to six months prior to starting dialysis. All-cause mortality and hospitalisation and quality of life were measured by the visual analogue scale and SF-36. SF-36 and KDQoL are validated measurement instruments for kidney diseases. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2012; Issue 1) which contains the Cochrane Renal Group's Specialised Register; MEDLINE (1966 to February 2012), EMBASE (1980 to February 2012). Search terms were approved by the Trial Search Co-ordinator. SELECTION CRITERIA Randomised controlled trials (RCTs), quasi-RCTs, prospective and retrospective longitudinal cohort studies were eligible for inclusion. DATA COLLECTION AND ANALYSIS Two authors independently assessed study quality and extracted data. Events relating to adverse effects were collected from the studies. MAIN RESULTS No RCTs or quasi-RCTs were identified. There were 40 longitudinal cohort studies providing data on 63,887 participants; 43,209 (68%) who were referred early and 20,678 (32%) referred late.Comparative mortality was higher in patients referred to specialist services late versus those referred early. Risk ratios (RR) for mortality reductions in patients referred early were evident at three months (RR 0.61, 95% CI 0.55 to 0.67; I² = 84%) and remained at five years (RR 0.66, 95% CI 0.60 to 0.71; I² = 87%). Initial hospitalisation was 9.12 days shorter with early referral (95% CI -10.92 to -7.32 days; I² = 82%) compared to late referral. Pooled analysis showed patients referred early were more likely than late referrals to initiate RRT with peritoneal dialysis (RR 1.74, 95% CI 1.64 to 1.84; I² = 92%).Patients referred early were less likely to receive temporary vascular access (RR 0.47, 95% CL 0.45 to 0.50; I² = 97%) than those referred late. Patients referred early were more likely to receive permanent vascular access (RR 3.22, 95% CI 2.92 to 3.55; I² = 97%). Systolic blood pressure (BP) was significantly lower in early versus late referrals (MD -3.09 mm Hg, 95% CI -5.23 to -0.95; I² = 85%); diastolic BP was significantly lower in early versus late referrals (MD -1.64 mm Hg, 95% CI -2.77 to -0.51; I² = 82%). EPO use was significantly higher in those referred early (RR 2.92, 95% CI 2.42 to 3.52; I² = 0%). eGFR was higher in early referrals (MD 0.42 mL/min/1.73 m², 95% CI 0.28 to 0.56; I² = 95%). Diabetes prevalence was similar in patients referred early and late (RR 1.05, 95% CI 0.96 to 1.15; I² = 87%) as was ischaemic heart disease (RR 1.05, 95% CI 0.97 to 1.13; I² = 74%), peripheral vascular disease (RR 0.99, 95% CI 0.84 to 1.17; I² = 90%), and congestive heart failure (RR 1.00, 95% CI 0.86 to 1.15; I² = 92%). Inability to walk was less prevalent in early referrals (RR 0.66, 95% CI 0.51 to 0.86). Prevalence of chronic obstructive pulmonary disease was similar in those referred early and late (RR 0.89, 95% CI 0.70 to 1.14; I² = 94%) as was cerebrovascular disease (RR 0.90, 95% CI 0.74 to 1.11; I² = 83%).The quality of the included studies was assessed as being low to moderate based on the Newcastle-Ottawa Scale. Slight differences in the definition of early versus late referral infer some risk of bias. Generally, heterogeneity in most of the analyses was high. AUTHORS' CONCLUSIONS Our analysis showed reduced mortality and mortality and hospitalisation, better uptake of peritoneal dialysis and earlier placement of arteriovenous fistulae for patients with chronic kidney disease who were referred early to a nephrologist. Differences in mortality and hospitalisation data between the two groups were not explained by differences in prevalence of comorbid disease or serum phosphate. However, early referral was associated with better preparation and placement of dialysis access.

Abstract
BACKGROUND/AIMS Suboptimal initiation of conventional hemodialysis is associated with poor clinical outcomes. In this study, we aimed to ascertain the determinants and adverse events associated with suboptimal starts in home hemodialysis (HHD). METHODS We conducted a retrospective cohort study including consecutive incident HHD patients from January 1996 to December 2011. All patients had HHD as their first renal replacement therapy or returned to HHD after kidney transplantation. A suboptimal start was defined by dialysis initiation as an inpatient or with a central venous catheter. The primary outcome was time to first hospitalization, technique failure or death. Secondary outcomes included hospitalization rate, hospital days and determinants of suboptimal starts. Suboptimal starts were further categorized as unavoidable as adjudicated by two independent observers with prespecified criteria. RESULTS Among 95 incident HHD patients, 44 (46%) and 51 (54%) had optimal and suboptimal starts, respectively. A suboptimal start was associated with a shorter time to the primary outcome (log-rank p < 0.001). In a multivariable Cox proportional hazards model, the hazard ratio for the composite outcome (comparing suboptimal to optimal starts) was 2.94 (95% confidence interval, CI, 1.49-5.78, p = 0.002). Transplantation clinic follow-up (OR 3.18, 95% CI 1.15-8.79) and the Charlson comorbidity index (OR 1.47, 95% CI 1.09-1.97) were associated with higher odds of suboptimal start. CONCLUSION Suboptimal initiation of HHD is associated with adverse clinical events including early hospitalization. Given the high proportion of suboptimal starts in patients returning from transplantation, better incorporation of dialysis planning and renal replacement therapy education is warranted.

Abstract
BACKGROUND/AIMS Pre-end-stage renal disease (ESRD) care is associated with improved outcomes among patients receiving dialysis. It is unknown what proportion of US micropolitan and rural dialysis patients receive pre-ESRD care and benefit from such care when compared to urban. METHODS A retrospective cohort study was performed using data from the US Renal Data System. Patients ≥18 years old who initiated dialysis in 2006 and 2007 were classified as rural, micropolitan or urban and the prevalence of pre-ESRD care (early nephrology care >6 months, permanent vascular access, -dietary education) was determined using the medical evidence report. The association of pre-ESRD care with dialysis mortality and transplantation was assessed using Cox regression with stratification for geographic residence. RESULTS Of 204,463 dialysis patients, 80% were urban, 10.2% were micropolitan and 9.8% were rural. Overall attainment of pre-ESRD care was poor. After adjustment, there were no significant geographic differences in attainment of early nephrology care or permanent dialysis access. Receiving care reduced all-cause mortality and increased the likelihood of transplantation to a similar degree regardless of geographic residence. Both micropolitan and rural patients received less dietary education (relative risk = 0.80, 95% CI = 0.76-0.84 and relative risk = 0.85, 95% CI = 0.80-0.89, respectively). CONCLUSION Among patients who receive dialysis, the prevalence of early nephrology care and permanent dialysis access is poor and does not vary by geographic residence. Micropolitan and rural patients receive less dietary education despite an observed mortality benefit, suggesting that barriers may exist to quality dietary care in more remote locations.

Abstract
Background Few studies in India as well as in most developing countries have compared the mortality and morbidity rates between chronic kidney disease patients who were referred early to nephrologists and those who were referred late. Objectives To study the mortality and morbidity patterns and to compare the various clinical parameters between the abovementioned early and late referrals. Patients and Methods Fifty consecutive chronic kidney disease patients were followed up for one year. They were then classified as early referral (patients who underwent dialysis more than three months after the referral) and late referral (patients who underwent dialysis within three months of the referral). Clinical, laboratory parameters, and mortality patterns were compared between the two groups. Results The blood pressure, hemoglobin, glomerular filtration rate, and calcium and phosphate values were better in the early referral group. Among the 24 complications that occurred, 17 (70.8%) were seen among the patients who were referred late. Among the 13 deaths that occurred, only one belonged to the early referral group. Conclusions We observed that the mortality rate and clinical parameters were better in patients who were referred early to nephrologists.

Abstract
Previous studies have suggested that early initiation of dialysis therapy was not superior in terms of patient survival. In this study, we analyzed the effects of renal function at the start of renal replacement therapy (RRT), duration of nephrology care, and comorbidity on 12-month survival of end-stage renal disease (ESRD) patients. The subjects in this study were 9695 new ESRD patients who started RRT in 2007. The average age of the subjects was 67.5 years, 64.1% of the subjects were male, and 42.9% had diabetes. During the 12-month period after the start of RRT, 1546 patients died, and 35 patients received renal transplantation. Average estimated glomerular filtration rate (eGFR) at the initiation of dialysis was 6.52 ± 4.20 mL/min/1.73 m(2) . By unadjusted logistic analysis, one-year Odds Ratio (OR) of mortality in patients with eGFR more than 4-6 mL/min/1.73 m(2) was increased with increased eGFR at dialysis initiation, but the OR was identical among the groups with eGFR less than 4 mL/min/1.73 m(2) . After adjustment for age, gender, underlying renal diseases, and other clinical characteristics at dialysis initiation, OR was identical among the groups with eGFR less than 8 mL/min/1.73 m(2) . Furthermore, an OR increment was observed in eGFR less than 4 mL/min/1.73 m(2) group. In terms of the duration of nephrology care before dialysis initiation, 6 months or longer of nephrology care significantly decreased the OR of mortality after adjustment of covariance. Not only patients with sufficient residual renal function at the initiation of dialysis, but also patients with very low eGFR at the initiation of dialysis showed poor survival.

Abstract
In industrialized countries, renal epidemiology is faced with the growing epidemic of diabetes as cause of renal involvement or as an associated condition. In France, recent studies estimate that 400,000+ diabetics have a glomerular filtration rate lower than 60 mL/min/1.73 m², and that 7000+ are prevalent in dialysis. The vast majority has type 2 diabetes. In type 1 diabetes, renal prognosis improved over the last decade due to available aggressive glycemic control and treatment with renin-angiotensin system inhibitors. Diabetes has a negative impact on survival in end-stage renal disease, particularly for type 1 diabetes patients and for women with diabetes. In type 2 diabetes, improvement in early access to renal transplant could lead to improvement in outcomes, whereas they are usually contra-indicated for transplant because rapid decline in cardiovascular status on dialysis. All these epidemiological data help us to implement preventing measures and further researches in order to improve diabetes patient prognosis.

Abstract
Background Chronic kidney disease (CKD) is an emerging worldwide problem. The lack of attention paid to kidney disease is well known and has been described in previous publications. However, little is known about the magnitude of the problem in highly specialized hospitals where serum creatinine values are used to estimate GFR values. Methods We performed a cross-sectional evaluation of hospitalized adult patients who were admitted to the medical or surgical department of Santa Maria della Misericordia Hospital in 2007. Information regarding admissions was derived from a database. Our goal was to assess the prevalence of CKD (defined as an estimated glomerular filtration rate [eGFR] < 60 mL/min/1.73 m2) and detection of CKD using diagnostic codes (Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM]). To reduce the impact of acute renal failure on the study, the last eGFR obtained during hospitalization was the value used for analysis, and intensive care and nephrology unit admissions were excluded. We also excluded patients who had ICD-9-CM codes for renal replacement therapy, acute renal failure, and contrast administration listed as discharge diagnoses. Results Of the 18,412 patients included in the study, 4,748 (25.8%) had reduced eGFRs, falling into the category of Kidney Disease Outcomes Quality Initiative (KDOQI) stage 3 (or higher) CKD. However, the diagnosis of CKD was only reported in 19% of these patients (904/4,748). It is therefore evident that there was a "gray area" corresponding to stage 3 CKD (eGFR 30-59 ml/min), in which most CKD diagnoses are missed. The ICD-9 code sensitivity for detecting CKD was significantly higher in patients with diabetes, hypertension, and cardiovascular disease (26.8%, 22.2%, and 23.7%, respectively) than in subjects without diabetes, hypertension, or cardiovascular disease (p < 0.001), but these values are low when the widely described relationship between such comorbidities and CKD is considered. Conclusion Although CKD was common in this patient population at a large inpatient regional hospital, the low rates of CKD detection emphasize the primary role nephrologists must play in continued medical education, and the need for ongoing efforts to train physicians (particularly primary care providers) regarding eGFR interpretation and systematic screening for CKD in high-risk patients (i.e., the elderly, diabetics, hypertensives, and patients with CV disease).

Abstract
Late referral of patients with chronic kidney disease (CKD) is a known problem and a major challenge for practising nephrologists since decades. In this review we report about the reasons for late referral, its epidemiology and socioeconomic impact and the medical particularities of late referred patients. We furthermore highlight on the efforts which have been undertaken so far to avoid late referral and should be undertaken in future to face the ever growing numbers of chronic kidney disease patients.

Abstract
BACKGROUND Chronic kidney disease (CKD) is a powerful risk factor for all-cause mortality and its most common aetiology, cardiovascular (CV) mortality. Mineral metabolism disturbances occur very early during the course of CKD but their control has been poor. A number of studies have assessed the relationship between all-cause mortality, CV mortality and events with mineral disturbances in CKD patients, but with considerable discrepancy and heterogeneity in results. Thus, a systematic review was conducted to assess methodological and clinical heterogeneity by comparing designs, analytical approaches and results of studies. METHODS Medline, EMBASE and Cochrane databases were systematically searched for articles published between January 1980 and December 2007. RESULTS Thirty-five studies were included in the review. All-cause mortality was the most commonly assessed outcome (n = 29). Data on CV mortality risk (n = 11) and CV events (congestive heart failure, stroke, myocardial infarction) (n = 4) are limited. The studies varied in populations scrutinized, exposure assessments, covariates adjusted and reference mineral levels used in risk estimation. A significant risk of mortality (all-cause, CV) and of CV events was observed with mineral disturbances. The data supported a greater mortality risk with phosphorus, followed by calcium and parathyroid hormone (PTH). The threshold associated with a significant all-cause mortality risk varied from 3.5-3.9 mg/dL (reference: 2.5-2.9) to 6.6-7.8 mg/dL (reference: 4.4-5.5) for high phosphorus, <3 mg/dL (reference: 5-7) to <5 mg/dL (reference: 5-6) for low phosphorus, 9.7-10.2 mg/dL (reference: < or =8.7) to >10.5 mg/dL (reference: 9-9.5) for high calcium, < or =8.8 mg/dL (reference: >8.8) to <9 mg/dL (reference: 9-9.5) for low calcium and >300 pg/mL (reference: 200-300) to >480 pg/mL (reference: < or =37) for PTH. Thresholds at which the CV mortality risk significantly increased were >5.5 (reference: 3.5-5.5) and >6.5 mg/dL (reference: <6.5) for phosphorus and >476.1 pg/mL (reference: <476.1) for PTH. CONCLUSIONS Serious limitations were observed in the quality and methodology across studies. In spite of enormous heterogeneity across studies, a significant mortality risk was observed with mineral disturbances in dialysis patients. Data on risk in pre-dialysis patients were less conclusive due to even more limited (numerically) evidence.

Abstract
OBJECTIVES To define the cost of care and evaluate interventions associated with improving outcomes and delaying the progression of chronic kidney disease (CKD). METHODS Using the PubMed database, a systematic review of the literature was conducted describing (i) the cost of care associated with treating earlier stages of CKD, and (ii) the role of early referral, erythropoiesis-stimulating proteins and anti-hypertensive agents in improving clinical outcomes and reducing the cost of CKD. RESULTS The higher costs associated with treatment of the CKD population are largely due to higher rates and duration of comorbidity-driven hospitalizations. Studies suggest that early referral to a nephrologist, use of erythropoiesis-stimulating proteins and anti-hypertensive agents may be associated with better outcomes and lower costs. In some instances, however, higher target haemoglobin levels could have harmful effects in CKD patients. CONCLUSION The substantial costs incurred during earlier stages of CKD increase markedly during the transition to renal replacement and remain elevated thereafter. An increase in awareness among health care providers may result in more timely interventions. More proactive management, in turn, can lead to improved clinical and economic outcomes through the slowing of disease progression and prevention of comorbidities.

Abstract
OBJECTIVE We aimed to update the epidemiology of type 1 and type 2 diabetic patients among the incident end-stage renal disease (ESRD) population in Australia and New Zealand (ANZ) and to determine whether outcome is worse for diabetic women, as described in the general population. RESEARCH DESIGNS AND METHODS All resident adults of ANZ who began renal replacement therapy (RRT) from 1 April 1991 to 31 December 2005 were included using data from the ANZ Dialysis and Transplant Registry. Incidence rates, RRT, and survival were analyzed. Risk factors for death were assessed using Cox regression. RESULTS The study included 1,284 type 1 diabetic (4.5%), 8,560 type 2 diabetic (30.0%), and 18,704 nondiabetic (65.5%) patients. The incidence rate of ESRD with type 2 diabetes increased markedly over time (+10.2% annually, P < 0.0001). In patients aged <70 years, rates of renal transplantation in type 1 diabetic, type 2 diabetic, and nondiabetic patients were 41.8, 6.5 (P < 0.0001 vs. other patients), and 40.9% (P = 0.56 vs. type 1 diabetic patients), respectively. Compared with nondiabetic patients, the adjusted hazard ratio (HR) for death was 1.64 (P < 0.0001) in type 1 diabetes and 1.13 (P < 0.0001) in type 2 diabetes. Survival rates per 5-year period improved by 6% in type 1 diabetic patients (P = 0.36), by 9% in type 2 diabetic patients (P < 0.0001), and by 5% in nondiabetic patients (P = 0.001). In type 2 diabetic patients aged >or=60 years, the adjusted HR for death in women versus men was 1.19 (P = 0.0003). CONCLUSIONS The incidence of ESRD with type 2 diabetes increased markedly. Despite high access to renal transplants, type 1 diabetic patients had a poor prognosis after starting RRT. Survival improved significantly in type 2 diabetic patients during the study period. Older type 2 diabetic women had a worse prognosis than older type 2 diabetic men.

Abstract
BACKGROUND Despite the amount of evidence regarding the negative impact of medical comorbidities after transplantation, little attention has been directly paid to the pattern of somatic comorbidities in renal transplant recipients. The aim of this study was to assess the prevalence of medical comorbidities after kidney transplantation. METHODS In a cross-sectional study during 2006, we evaluated 119 kidney transplant recipients for somatic comorbidities by using the Ifudu comorbidity index, which evaluated the presence of 14 chronic illnesses among patients undergoing maintenance hemodialysis. Correlations of the Ifudu score with demographic and clinical data were also studied. RESULTS Eighty-three (90.4%) subjects had at least one medical comorbidity. The mean comorbidity score was 5.17 +/- 4.50. The most frequent comorbidities were nonischemic heart diseases including hypertension (n=75; 63%), visual disturbances (n=42; 35.2%), low back pain and spine and joint disorders (n=30; 25.21%), and musculoskeletal disorders (n=28; 23.5%). A higher comorbidity score was significantly correlated with lower economic status (P<.05), but not with age, gender, marital status, educational level, cause, or duration of end-stage renal disease. CONCLUSION The prevalence of medical comorbidities among kidney transplant recipients seems to be high, with the highest prevalence due to nonischemic heart diseases, visual disturbances, and musculoskeletal disorders. This highlighted the necessity of providing posttransplant care by a multidisciplinary team of specialists.

Abstract
Renal impairment is frequent in aged diabetic patients, notably with type 2 diabetes. It results from a multifactorial pathogeny, particularly the combined actions of hyperglycaemia, arterial hypertension and ageing. Diabetic nephropathy (DN) is associated with an increased cardiovascular mortality. DN often leads to end stage renal failure (ESRF) which causes specific problems of decision and practical organization of extra-renal epuration in diabetic and aged patients. In the absence of renal biopsy, clinical signs are often insufficient to assess the diabetic origin of a nephropathy in an elderly diabetic patient. Prevention of DN is principally based on tight glycaemic and blood pressure control. The progression of renal lesions can be retarded by strict blood pressure control, notably by blocking of the renin-angiotensin system, if well tolerated in aged patients. It is absolutely necessary to avoid the worsening of renal lesions by potentially nephrotoxic products, notably non steroidal anti-inflammatory drugs (NSAIDs) and iodinated contrast media. At the stage of renal failure, it is important to adapt the antidiabetic treatment, and in the majority of the cases, to switch to insulin when glomerular filtration rate (GFR) is below 30 ml/mn/1.73 m2.

Abstract
The prevalence of patients with chronic kidney disease (CKD) in the US population is approximately 11%, and because of the increase in life expectancy and in diabetic nephropathy incidence, an exponential increase is predicted for the next decades. During the past decade, evidence that the progression of CKD can be attenuated by a multifactorial therapeutic approach has been increasing. However, a substantial percentage of patients with CKD will have progression to CKD stage V (ie, need for renal replacement therapy). Late referral of these patients (ie, <1 to 6 months before the start of renal replacement therapy) has been shown to be associated with higher mortality, morbidity, and costs. However, up to 64% of patients with CKD are still referred late. This review presents the available data on the epidemiology, causes, and consequences of late patient referral. Furthermore, it offers information to prevent late referral, improve CKD patient care, and change clinical practice.

Abstract
BACKGROUND Evaluation of adult candidates for kidney transplantation diverges from one centre to another. Concurrently, ethnic background, female gender, late referral to a nephrologist, distance from transplantation department and private ownership of a dialysis facility have been associated with poor access to kidney transplantation. We assessed determinants of access to a waiting list in a French community-based network of care. METHODS From July 1997 to June 2003, 1725 adults living in Lorraine, who started renal replacement therapy in one of the 13 facilities of the network, were included. We compared, first, the patients registered on the waiting list with those not registered and, second, the patients registered before starting dialysis with those registered after. RESULTS Using logistic regression, registration on the waiting list was exclusively associated with age and medical factors, except for one variable: medical follow-up in the department performing transplantation [odds ratio (OR): 1.67 (95%CI: 1.05-2.67)]. Registration before starting dialysis was not associated with medical factors but with age [OR of patients younger than 45 years vs those older than 65 years: 3.85 (95%CI: 1.05-24.92)] and medical follow-up in the department performing transplantation [OR: 3.56 (95%CI: 1.98-6.67)]. CONCLUSIONS In a French community-based network, patients followed by the nephrology department performing transplantation are more likely to be registered on the transplant waiting list early in the course of chronic kidney disease. Age over 55 per se is a considerable barrier to access to kidney transplantation. Medical guidelines should allow a standardization of criteria for registration.

Abstract
PURPOSE The purpose of this study was to evaluate the impact of a clinical nurse specialist-managed outpatient anemia management program on quality of life for patients with anemia related to chronic kidney disease. DESCRIPTION OF THE STUDY A retrospective study was conducted using information from the Medical Outcomes Short Form 36 Item Health Survey, which is completed by patients with anemia at their initial, 3-month, 6-month, and 12-month visits, and annually thereafter. Thirty-four patients completed the 3-month survey, 19 completed the 6-month survey, and 10 completed the 12-month survey. OUTCOMES There was a statistically significant increase in quality of life indicators at the 3 and 6 months' interval. The increase in physical and decrease in mental indicators were not substantiated through the 12-month interval. CONCLUSION Quality of life was significantly improved for patients in a clinical nurse specialist-managed outpatient anemia management program.

Abstract
INTRODUCTION Chronic kidney disease (CKD) is a major public health problem. We report an evaluation of the CKD perception from a French family physician's (FP) point of view. METHODS A questionnaire was sent to a representative and independently selected sample of 497 FP, i.e. 20% of the FP working in the administrative region Lorraine. There were 214 completed surveys, i.e. response rate: 43%. RESULTS Age of FP was: < 40 years of age: 13%, 40-50: 40%, > 50: 47%. The geographic working place was urban: 41%, rural: 22%, urban and rural: 37%. Ninety-nine per cent of FP has a nephrologist, devoted to CKD referral. Twenty-one per cent of FP has a comprehensive picture of CKD and 75% thinks that CKD diagnostic is difficult Thirty per cent of FP were aware of CKD guidelines. For FP, risk-factors for CKD were: hypertension: 93%, diabetes: 99%, age over 65: 64%, urinary infection: 34%, hematuria/proteinuria: 78%, anaemia: 43%, therapeutics associated with risk of renal injury: 79%, all of these circumstances: 20%. The referral decision to a nephrologist was done at a mean creatinine clearance of 41+/-12 ml/min. Age over 80, dementia, and cancer were considered to be a contra-indication of renal replacement therapy, for respectively 30%, 69%, and 63% of FP. CME was associated with better awareness of guidelines, and use of clearance rather than serum creatinin. CONCLUSION From FP point of view, overall awareness of CKD guidelines is low. In the context of the current nephrology services, greater sharing of CKD care with FP is needed.

Abstract
Epidemiologic data on end-stage renal disease (ESRD) treated with renal dialysis remain sparse and incomplete in France because there is no national registry of dialysis patients. The aim of this study was to determine the characteristics (age, gender, comorbidities, associated handicap) of patients treated with renal dialysis and to compare the dialysis regional practices. We performed a cross-sectional descriptive study from June 2 to June 8, 2003 in all renal dialysis units by enrolling all the patients residing in France with ESRD who were dialysed during that week, irrespective of the treatment they received or where they were being treated. In 2003, the type of dialysis units available and the technique they employ were quite different from one region to another, varying from 41.1 to 70.2% for highly specialized unit, 9.4 to 48.4% for self-care hemodialysis, and 2.9 to 26.5% for peritoneal dialysis.
