Individually adjusted absolute blood volume feedback control: A promising solution for intradialytic hypotension.

INTRODUCTION: Intradialytic hypotension (IDH) remains one of the most frequent complications associated to hemodialysis (HD), frequently triggered by a reduction in absolute blood volume (ABV) not compensated by vascular refilling. A recently developed dilutional method allows routinary measurement of ABV and, by a simple algorithm, may turn blood volume monitor (BVM) guided UF (ultrafiltration) biofeedback into an ABV control, automatically adjusting UF rate to maintain ABV above a preset threshold. The aim of this study is to identify an individual critical ABV threshold and test the ability of an ABV feedback control to avoid IDH. METHODS: We studied 24 patients throughout three consecutive midweek HD treatments. ABV and blood pressure (BP) were measured every 30 min and anytime the patient referred any symptoms to identify each patient's critical ABV (ABV at the time of hypotension). A fixed bolus dilution approach at the start of HD was used to calculate ABV. Then, patients were followed through three additional HD treatments and IDH development was analyzed. FINDINGS: Seventy-one treatments performed in 24 patients. ABV monitoring showed a constant decrease as HD treatment progressed. Thirteen IDH events were observed in eight different patients, with a mean systolic BP drop in IDH treatments of 37.38 ± 4.31 mmHg and a mean adjusted ABV at hypotension of 71.07 ± 14.88 mL/kg. Critical ABV was individually set in patients prone to IDH. As expected, ABV feedback control successfully maintained ABV over preset critical ABV. IDH events were avoided in 21 out of 22 treatments performed. ABV drop was successfully reduced, as well as SBP drop (despite similar UF than prior to ABV feedback control implementation). DISCUSSION: ABV feedback control avoided IDH in 21 out of 22 treatments performed by maintaining blood volume above critical ABV, significantly reducing ABV variations without compromising prescribed UF.

Development and validation of a nomogram to predict kidney survival at baseline in patients with C3 glomerulopathy.

Background: C3 glomerulopathy is a rare and heterogeneous complement-driven disease. It is often challenging to accurately predict in clinical practice the individual kidney prognosis at baseline. We herein sought to develop and validate a prognostic nomogram to predict long-term kidney survival. Methods: We conducted a retrospective, multicenter observational cohort study in 35 nephrology departments belonging to the Spanish Group for the Study of Glomerular Diseases. The dataset was randomly divided into a training group (n = 87) and a validation group (n = 28). The least absolute shrinkage and selection operator (LASSO) regression was used to screen the main predictors of kidney outcome and to build the nomogram. The accuracy of the nomogram was assessed by discrimination and risk calibration in the training and validation sets. Results: The study group comprised 115 patients, of whom 46 (40%) reached kidney failure in a median follow-up of 49 months (range 24-112). No significant differences were observed in baseline estimated glomerular filtration rate (eGFR), proteinuria or total chronicity score of kidney biopsies, between patients in the training versus those in the validation set. The selected variables by LASSO were eGFR, proteinuria and total chronicity score. Based on a Cox model, a nomogram was developed for the prediction of kidney survival at 1, 2, 5 and 10 years from diagnosis. The C-index of the nomogram was 0.860 (95% confidence interval 0.834-0.887) and calibration plots showed optimal agreement between predicted and observed outcomes. Conclusions: We constructed and validated a practical nomogram with good discrimination and calibration to predict the risk of kidney failure in C3 glomerulopathy patients at 1, 2, 5 and 10 years.

Longitudinal change in proteinuria and kidney outcomes in C3 glomerulopathy.

INTRODUCTION: The association between a change in proteinuria over time and its impact on kidney prognosis has not been analysed in complement component 3 (C3) glomerulopathy. This study aims to investigate the association between the longitudinal change in proteinuria and the risk of kidney failure. METHODS: This was a retrospective, multicentre observational cohort study in 35 nephrology departments belonging to the Spanish Group for the Study of Glomerular Diseases. Patients diagnosed with C3 glomerulopathy between 1995 and 2020 were enrolled. A joint modelling of linear mixed-effects models was applied to assess the underlying trajectory of a repeatedly measured proteinuria, and a Cox model to evaluate the association of this trajectory with the risk of kidney failure. RESULTS: The study group consisted of 85 patients, 70 C3 glomerulonephritis and 15 dense deposit disease, with a median age of 26 years (range 13-41). During a median follow-up of 42 months, 25 patients reached kidney failure. The longitudinal change in proteinuria showed a strong association with the risk of this outcome, with a doubling of proteinuria levels resulting in a 2.5-fold increase of the risk. A second model showed that a ≥50% proteinuria reduction over time was significantly associated with a lower risk of kidney failure (hazard ratio 0.79; 95% confidence interval 0.56-0.97; P < 0.001). This association was also found when the ≥50% proteinuria reduction was observed within the first 6 and 12 months of follow-up. CONCLUSIONS: The longitudinal change in proteinuria is strongly associated with the risk of kidney failure. The change in proteinuria over time can provide clinicians a dynamic prediction of kidney outcomes.

Comparison of 3 anti-PLA2R inmmunoassaysfor the diagnosis of idiopathic membranous nephropathy in an european population. A pilot study.

Membranous nephropathy (MN) is one of the most frequent causes of nephrotic syndrome. Renal biopsy is nowadays the gold standard for the diagnosis of MN. The presence of circulating PLA2R antibody is a very specific tool for the diagnosis of this disease, especially associated with primary or idiopathic MN (IMN), even though it can be also found in a small proportion of patients with secondary MN (SMN). This pilot study compares three different techniques for the detection of anti-PLA2R autoantibodies (immunofluorescence, ELISA immunoassay, and multiplex laser bead technology). Serum of 12 IMN and 9 SMN patients was obtained at diagnosis. Additionally, we employed serum samples of 15 healthy volunteers. From our patient cohort, we obtained a 7.75 RU/ml cut-off for the ELISA and 3104 MFI for the Luminex assays. The agreement between the three techniques improved considerably when applying the new cut-off points. As several authors have suggested, cut-offs may be calculated for each specific population instead of establishing global cut-off points. Patients with IMN showed significantly lower serum albumin levels and higher 24 h proteinuria compared to those with SMN. Analysis of ROC curves suggests that ELISA and LUMINEX assays are more useful than biochemical variables to differentiate patients with IMN and SMN. This pilot study contributes to confirming that the combination of ELISA and Luminex assays provide excellent sensitivity and specificity for the identification of IMN.

Effect of oral administration of docohexanoic acid on anemia and inflammation in hemodialysis patients: A randomized controlled clinical trial.

BACKGROUND & AIMS: Docohexanoic acid (DHA), a dietary n-3 polyunsaturated fatty-acid omega-3 (n-3, PUFA), showed potential beneficial effects in reducing all-cause mortality in hemodialysis (HD) patients. This randomized trial aimed to analyze whether DHA supplementation was a modulator of erythropoietin (EPO) response and inflammation in hemodialysis (HD) patients. METHODS: In this controlled clinical trial, 52 HD patients were randomized to either DHA supplementation (650 mg DHA/3 times/wk/post-HD session) or controls (usual care), with 8-weeks of follow-up. The primary outcome was to determine the correction of anemia measured by changes in the erythropoiesis-resistance index (ERI) to keep the hemoglobin level at recommended target value. Secondary outcomes include changes in inflammatory biomarkers: serum C-reactive protein, total homocysteine (tHcy) and expression of miR-146a. Laboratory measures were determined at baseline and at 8-weeks after the DHA supplementation or usual care in controls. Linear regression analysis was used to assess the effect of DHA supplementation, adjusting for baseline values and intervention. RESULTS: Forty-two HD patients (men: 69%; aged:66.7 ± 15.5 yrs; DM:19%), completed this study. The DHA effect significantly decreased EPO doses (-4158.7 UI/weekly; CI95%:-8123.7 to 193,6; p = 0.04), ERI (-9.25 UI weekly/kg BW/g/dL; CI95%:-15.5 to -2.9; p = 0.006), tHcy (-5.1 µmol/L; CI95%:-9.7 to -0.3; p = 0.03), and levels of miR-146a (-1.43; CI95%:-2.7 to -0.19; p = 0.03) in regression model. No adverse effects were found. CONCLUSION: The DHA supplementation enhances anemia management and attenuates inflammation response in this controlled trial in HD patients, when provided as coadjutant therapy together with usual medical care.

Validation of a Histologic Scoring Index for C3 Glomerulopathy.

RATIONALE & OBJECTIVE: A previous study that evaluated associations of kidney biopsy findings with disease progression in patients with C3 glomerulopathy (C3G) proposed a prognostic histologic index (C3G-HI) that has not yet been validated. Our objective was to validate the performance of the C3G-HI in a new patient population. STUDY DESIGN: Multicenter, retrospective cohort study. SETTING & PARTICIPANTS: 111 patients fulfilling diagnostic criteria of C3G between January 1995 and December 2019, from 33 nephrology departments belonging to the Spanish Group for the Study of Glomerular Diseases (GLOSEN). PREDICTORS: Demographic, clinical parameters, C3G-HI total activity score, and the C3G-HI total chronicity score. OUTCOME: Time to kidney failure. ANALYTICAL APPROACH: Intraclass correlation coefficients and κ statistic were used to summarize inter-rater reproducibility for assessment of histopathology in kidney biopsies. The nonlinear relationships of risk of kidney failure with the total activity score and total chronicity score were modeled using Cox proportional hazards analysis that incorporated cubic splines. RESULTS: The study group included 93 patients with C3 glomerulonephritis and 18 with dense-deposit disease. Participants had an overall meanage of 35±22 (SD) years. Forty-eight patients (43%) developed kidney failure after a mean follow-up of 65±27 months. The overall inter-rater reproducibility was very good for the total activity score (intraclass correlation coefficient [ICC]=0.63) and excellent for total chronicity score (ICC=0.89). Baseline estimated glomerular filtration rate (eGFR), 24-hour proteinuria, and treatment with immunosuppression were the main determinants of kidney failure in a model with only clinical variables. Only tubular atrophy and interstitial fibrosis were identified as predictors in a model with histological variables. When the total activity score and total chronicity score were added to the model, only the latter was identified as an independent predictor of kidney failure. LIMITATIONS: Only a subset of the kidney biopsies was centrally reviewed. Residual confounding. CONCLUSIONS: We validated the performance of C3G-HI as a predictor of kidney failure in patients with C3G. The total chronicity score was the principal histologic correlate of kidney failure.

Mycophenolate Mofetil in C3 Glomerulopathy and Pathogenic Drivers of the Disease.

BACKGROUND AND OBJECTIVES: C3 glomerulopathy is a complement-mediated disease arising from abnormalities in complement genes and/or antibodies against complement components. Previous studies showed that treatment with corticosteroids plus mycophenolate mofetil (MMF) was associated with improved outcomes, although the genetic profile of these patients was not systematically analyzed. This study aims to analyze the main determinants of disease progression and response to this therapeutic regimen. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We conducted a retrospective, multicenter, observational cohort study in 35 nephrology departments belonging to the Spanish Group for the Study of Glomerular Diseases. Patients diagnosed with C3 glomerulopathy (n=81) or dense deposit disease (n=16) between January 1995 and March 2018 were enrolled. Multivariable and propensity score matching analyses were used to evaluate the association of clinical and genetic factors with response to treatment with corticosteroids and MMF as measured by proportion of patients with disease remission and kidney survival (status free of kidney failure). RESULTS: The study group comprised 97 patients (84% C3 glomerulopathy, 16% dense deposit disease). Forty-two patients were treated with corticosteroids plus MMF, and this treatment was associated with a higher rate of remission and lower probability of kidney failure (79% and 14%, respectively) compared with patients treated with other immunosuppressives (24% and 59%, respectively), or ecluzimab (33% and 67%, respectively), or conservative management (18% and 65%, respectively). The therapeutic superiority of corticosteroids plus MMF was observed both in patients with complement abnormalities and with autoantibodies. However, patients with pathogenic variants in complement genes only achieved partial remission, whereas complete remissions were common among patients with autoantibody-mediated forms. The main determinant of no remission was baseline proteinuria. Relapses occurred after treatment discontinuation in 33% of the patients who had achieved remission with corticosteroids plus MMF, and a longer treatment length of MMF was associated with a lower risk of relapse. CONCLUSIONS: The beneficial response to corticosteroids plus MMF treatment in C3 glomerulopathy appears independent of the pathogenic drivers analyzed in this study.

IgA Nephropathy in Elderly Patients.

BACKGROUND AND OBJECTIVES: Some studies suggest that the incidence of IgA nephropathy is increasing in older adults, but there is a lack of information about the epidemiology and behavior of the disease in that age group. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: In this retrospective multicentric study, we analyzed the incidence, forms of presentation, clinical and histologic characteristics, treatments received, and outcomes in a cohort of 151 patients ≥65 years old with biopsy-proven IgA nephropathy diagnosed between 1990 and 2015. The main outcome was a composite end point of kidney replacement therapy or death before kidney replacement therapy. RESULTS: We found a significant increase in the diagnosis of IgA nephropathy over time from six patients in 1990-1995 to 62 in 2011-2015 (P value for trend =0.03). After asymptomatic urinary abnormalities (84 patients; 55%), AKI was the most common form of presentation (61 patients; 40%). Within the latter, 53 (86%) patients presented with hematuria-related AKI (gross hematuria and tubular necrosis associated with erythrocyte casts as the most important lesions in kidney biopsy), and eight patients presented with crescentic IgA nephropathy. Six (4%) patients presented with nephrotic syndrome. Among hematuria-related AKI, 18 (34%) patients were receiving oral anticoagulants, and this proportion rose to 42% among the 34 patients older than 72 years old who presented with hematuria-related AKI. For the whole cohort, survival rates without the composite end point were 74%, 48%, and 26% at 1, 2, and 5 years, respectively. Age, serum creatinine at presentation, and the degree of interstitial fibrosis in kidney biopsy were risk factors significantly associated with the outcome, whereas treatment with renin-angiotensin-aldosterone blockers was associated with a lower risk. Immunosuppressive treatments were not significantly associated with the outcome. CONCLUSIONS: The diagnosis of IgA nephropathy among older adults in Spain has progressively increased in recent years, and anticoagulant therapy may be partially responsible for this trend. Prognosis was poor. PODCAST: This article contains a podcast at https://www.asn-online.org/media/podcast/CJASN/2019_07_16_CJASNPodcast_19_08_.mp3.

Arteriovenous fistulae after renal biopsy: diagnosis and outcomes using Doppler ultrasound assessment.

BACKGROUND: Percutaneous renal biopsy (PRB) is an important technique providing relevant information to guide diagnosis and treatment in renal disease. As an invasive procedure it has complications. Most studies up to date have analysed complications related to bleeding. We report the largest single-center experience on routine Doppler ultrasound (US) assessment post PRB, showing incidence and natural history of arteriovenous fistulae (AVF) post PRB. METHODS: We retrospectively analysed 327 consecutive adult PRB performed at Ramon Cajal University Hospital between January 2011 and December 2014. All biopsies were done under real-time US guidance by a trained nephrologist. Routine Doppler mapping and kidney US was done within 24 h post biopsy regardless of symptoms. Comorbidities, full blood count, clotting, bleeding time and blood pressure were recorded at the time of biopsy. Post biopsy protocol included vitals and urine void checked visually for haematuria. Logistic regression was used to investigate links between AVF, needle size, correcting for potential confounding variables. RESULTS: 46,5% were kidney transplants and 53,5% were native biopsies. Diagnostic material was obtained in 90,5% (142 grafts and 154 native). Forty-seven AVF's (14.37%) were identified with routine kidney Doppler mapping, 95% asymptomatic (n = 45), 28 in grafts (18.4%) and 17 natives (9.7%) (p-value 0.7). Both groups were comparable in terms of comorbidities, passes, cylinders or biopsy yield (p-value NS). 80% were <1 cm in size and 46.6% closed spontaneously in less than 30 days (range 3-151). Larger AVF's (1-2 cm) took a mean of 52 days to closure (range 13-151). Needle size was not statistically significant factor for AVF (p-value 0.71). CONCLUSIONS: Contrary to historical data published, AVF's are a common complication post PRB that can be easily missed. Routine US Doppler mapping performed by trained staff is a cost-effective, non-invasive tool to diagnose and follow up AVF's, helping to assess management.

Síndrome de secreción inadecuada de hormona antidiurética, hiponatremia y antipsicóticos. Revisión de la literatura a propósito de un caso / Syndrome of inappropriate antidiuretic hormone secretion, hyponatraemia and antipsychotics. Review of the evidence and case report

Introducción. La hiponatremia es un efecto secundario asociado al uso de psicofármacos, entre ellos, los antipsicóticos. El síndrome de secreción inadecuada de hormona antidiurética y la polidipsia se han postulado como mecanismos etiopatogénicos subyacentes. Asimismo, se propone que exista una afectación biológica en la esquizofrenia que promueva la hiponatremia. Caso clínico. Presentamos a una paciente de 45 años con diagnóstico de esquizofrenia que comienza con un síndrome de secreción inadecuada de hormona antidiurética probablemente secundario a palmitato de paliperidona. Discusión. A partir de este caso, realizamos una revisión de la literatura disponible y planteamos la interrelación de la hiponatremia, el síndrome de secreción inadecuada de hormona antidiurética, la polidipsia, la propia psicosis y otros mecanismos etiopatogénicos. Conclusiones. La hiponatremia es una complicación importante e impredecible, de la que desconocemos su fisiopatología exacta en pacientes psicóticos. Son necesarios más estudios que esclarezcan su patogenia y determinen la necesidad de seguimiento analítico de pacientes que reciben tratamiento antipsicótico, sobre todo aquellos con diagnóstico de esquizofrenia (AU)

Introduction. Hyponatraemia is an adverse drug reaction to psychotropic medication, among them the antipsychotics. Syndrome of inappropriate antidiuretic hormone secretion and polydipsia have been suggested as aetiopathogenic mechanisms. Moreover, it has been postulated that there is a biological dysfunction in schizophrenia that induces hyponatraemia. Case report. A case is presented on a 45-year old woman with schizophrenia who has an syndrome of inappropriate antidiuretic hormone secretion, which was suspected of being due to paliperidone palmitate. Discussion. A review was made of the available published evidence and proposed the relationship between hyponatraemia, syndrome of inappropriate antidiuretic hormone secretion, polydipsia, the psychosis itself, and other aetiopathogenic mechanisms. Conclusions. Hyponatraemia is an important and unpredictable complication, for which its pathophysiology remains unknown. Further studies are needed to establish its pathogenic mechanisms and to determine the need of analytical monitoring in patients who are on treatment with antipsychotics, especially those with schizophrenia (AU)

Choosing conservative therapy in chronic kidney disease.

INTRODUCTION: Incidence of use for various renal replacement therapies is well-known, but no data are available on conservative treatment use. OBJECTIVE: To assess the proportion of patients with chronic kidney failure receiving a conservative treatment. RESULTS: From July 1, 2013 to June 30, 2014, 232 patients with stage 5 CKD were seen in the Nephrology Department. After having received information on existing therapeutic options and having known the opinion of their treating physicians, 81 patients (35%) selected hemodialysis, 56 (24%) preferred peritoneal dialysis, 5 (2%) selected a preemptive transplant from a living donor, and in 90 (39%) a conservative treatment option was selected. In a univariate analysis using logistic regression, variables associated to a preference for conservative treatment were age, Charlson index excluding age, degree of walking difficulties, and functional dependence level, with the first three factors achieving statistical significance in a multivariate analysis. Presence of a severe disease resulting in a poor prognosis was the main reason for selecting a conservative treatment (49%), with the second one being patient refusal to receive a renal replacement therapy (26%). Mortality rate was 8.2/100 patient-months in conservative therapy group versus 0.6/100 patient-months in patients receiving renal replacement therapy (P<.001). In patients receiving conservative therapy, baseline glomerular filtration rate at the time of study enrollment was the sole variable showing a significant impact on survival. CONCLUSIONS: About 39% of patients with stage 5 CKD seen over a 1-year period in the Nephrology Department received conservative therapy. Age, co-morbidity, and functional disability were the factors associated to selecting a conservative therapy option.

Elección de tratamiento conservador en la enfermedad renal crónica / Choosing conservative therapy in chronic kidney disease

Introducción: La incidencia de las diversas modalidades de tratamiento sustitutivo renal es conocida, pero no sucede así con la opción de tratamiento conservador. Objetivo: Conocer la proporción de pacientes con insuficiencia renal crónica sometidos a tratamiento conservador. Resultados: Entre el 1 de julio de 2013 y el 30 de junio de 2014 fueron atendidos en el Servicio de Nefrología 232 casos con ERC en estadio 5. Tras recibir una información sobre las diversas alternativas terapéuticas y con la opinión del médico responsable, 81 enfermos (35%) optaron por el tratamiento con hemodiálisis, 56 (24%) mostraron preferencia por la diálisis peritoneal, 5 (2%) por el trasplante de vivo prediálisis, y en 90 enfermos (39%) se decidió realizar tratamiento conservador. En el análisis univariante de regresión logística las variables asociadas a la elección de tratamiento conservador fueron la edad, el índice de Charlson sin contar la edad, el grado de dificultad para la marcha y el grado de dependencia funcional, quedando los 3 primeros con significación significativa en el análisis multivariante. La existencia de una enfermedad grave con mal pronóstico a corto plazo fue la principal causa por la que se indicó el tratamiento conservador (49%), y la segunda fue la negativa del enfermo a recibir tratamiento sustitutivo renal (26%). La tasa de mortalidad fue de 8,2/100 enfermos-mes en el grupo de tratamiento conservador y de 0,6/100 enfermos-mes en el grupo que decidió optar al tratamiento sustitutivo renal (p<0,001). En el grupo tratado de forma conservadora, el filtrado glomerular en el momento de inclusión en el estudio fue la única variable que influyó de forma estadísticamente significativa sobre la supervivencia. Conclusiones: El 39% de los pacientes con ERC en estadio 5 atendidos durante un año en el Servicio de Nefrología fueron tratados de forma conservadora. Edad, comorbilidad y discapacidad funcional fueron las variables que se relacionaron con la elección de tratamiento conservador (AU)

Programa de atención domiciliaria a pacientes con enfermedad renal crónica avanzada. Experiencia de dos años / Home care programme for patients with advanced chronic kidney disease. A two-year experience

Introducción: La atención sanitaria de los pacientes con enfermedad renal crónica avanzada (ERCA) bajo tratamiento conservador plantea con gran frecuencia problemas asistenciales de difícil solución. Muchos de ellos son enfermos añosos, con dificultad de movilidad, en los que los desplazamientos al centro hospitalario suponen una gran dificultad. A finales del año 2011 iniciamos un programa basado en la asistencia y el control de estos enfermos por los equipos de Atención Primaria. Material y métodos: A los pacientes con ERCA que han elegido tratamiento conservador, se les ofrece la posibilidad de recibir una asistencia fundamentalmente domiciliaria por el médico de Atención Primaria, bajo la coordinación de la Unidad de Cuidados Paliativos y del Servicio de Nefrología. Resultados: Durante los años 2012 y 2013, 50 enfermos recibieron tratamiento en este programa. Edad media: 81 años, índice edad-comorbilidad de Charlson: 10, y filtrado glomerular medio 11,8 ml/min/1,73 m². El tiempo de seguimiento medio por enfermo (hasta el fallecimiento o hasta el 31/12/2013) fue de 184 días. Durante este período, el 44 % de los enfermos no tuvo que acudir al Servicio de Urgencias del hospital, y el 58 % no precisó ingreso hospitalario. Fallecieron 29 de los 50 enfermos, tras un tiempo medio de permanencia en el programa de 163 días; en 14 de ellos (48 %), el sitio de fallecimiento fue su domicilio. Conclusiones: Nuestra experiencia indica que con soporte de la Unidad de Cuidados Paliativos y del Servicio de Nefrología, el paciente con ERCA no candidato a diálisis puede ser controlado en su domicilio por Atención Primaria (AU)

Introduction: Healthcare for patients with advanced chronic kidney disease (ACKD) on conservative treatment very often poses healthcare problems that are difficult to solve. Many patients are elderly and have mobility problems, and it is very difficult for them to travel to hospital. At the end of 2011, we began a programme based on the care and monitoring of these patients by Primary Care teams. Material and method: ACKD patients who opted for conservative treatment were offered the chance to be cared for mainly at home by the Primary Care doctor, under the coordination of the Palliative Care Unit and the Nephrology Department. Results: During 2012 and 2013, 50 patients received treatment in this programme. Mean age: 81 years, Charlson age-comorbidity index: 10 and mean glomerular filtration rate: 11.8ml/min/1.73.m². The mean patient follow-up time (until death or until 31/12/2013) was 184 days. During this period, 44% of patients did not have to visit the hospital’s Emergency Department and 58% did not require hospitalisation. 29 of the 50 patients died after a mean time of 163 days on the programme; 14 (48%) died at home. Conclusions: Our experience indicates that with the support of the Palliative Care Unit and the Nephrology Department, ACKD patients who are not dialysis candidates may be monitored at home by Primary Care (AU)
