<b><i>Introduction:</i></b> When choosing a modality for outpatient renal replacement therapy, patients and medical providers have 3 options to choose from in-center hemodialysis (HD), home HD (HHD), and peritoneal dialysis (PD). In 2017, just over 10% of incident ESKD patients were on a home dialysis modality. We set out to determine outcomes of dialysis modality education in both pre-dialysis and dialysis patients. Moreover, we examined barriers that preclude patients from choosing home dialysis. <b><i>Methods:</i></b> This was a single-center, retrospective study looking at patients who were referred to the CKD educator for dialysis modality education between January 1, 2019, and March 31, 2020. Patient demographics, preferred language of communication, stage of renal disease, and reasons for patients’ refusal to undertake a home dialysis modality were recorded. Patients’ average household income and driving distance to our home dialysis unit were calculated using their home zip code. <b><i>Results:</i></b> 167 patients were referred for CKD education. Mean age was 60 years, and 59% male, 42% African American, 22% White, 7% Asian, and 28% were Hispanic or Latino. Only 23% of the total cohort chose in-center HD, while 74% chose a home dialysis modality (59% PD and 15% HHD), and the remaining patients remained undecided. 56% of in-center HD patients chose a home dialysis modality. The most commonly cited barriers to home dialysis were lack of a care partner, lack of home space, and patient preference. <b><i>Limitations:</i></b> Over 90% of our patients reside in NY City where home space is limited. We require in our home HD program that patients have a trained care partner present during their treatments. We cannot assume that all CKD stage-4 patients or higher were either referred for CKD education or followed through on the referral. <b><i>Conclusions:</i></b> A large discrepancy between informed patients’ choices and the reality of the current dialysis landscape. Absence of a care partner, lack of home space, and patients not deemed appropriate surgical candidates were the main driving forces in their not opting for a home modality.

Abstract Background and Aims Vascular calcification (VC) plays a major role in cardiovascular disease (CVD), which is one of the main causes of mortality in patients with chronic kidney disease (CKD). The study aims at early detection of breast arterial calcification (BAC) in different stages of CKD (stage 2, 3& 4) patients as an indicator of systemic VC. Method A case control study was conducted targeting CKD women, aged 18- 60 years old. The sample was divided into 3 groups; A,B,C (representing stage 2, 3 & 4 of CKD) from women who attended nephrology and Internal medicine clinics and admitted in inpatient ward in Suez Canal University Hospital. A 4th group (D) was formed as a control group and included women with normal kidney functions (each group (A, B, C, D) include 22 women). The selected participants were subjected to history taking, mammogram to detect BAC and biochemical assessment of lipid profile, Serum creatinine (Cr), Mg, P, Ca, PTH and FGF23. Results Our study detected presence of BAC in about 81.8% of hypertensive stage 4 CKD patients compared with 50% in stage 3 CKD, also in the majority of stage 4 CKD patients who had abnormal lipid profile parameters and electrolyte disturbance. Most of the variables had statistical significance regarding the presence of BAC. Conclusion Although it is difficult to determine the definite stage at which the risk of VC begins but in our study, it began late in stage 2 CKD, gradually increased prevalence through stage 3 and became significantly higher in stage 4. These results suggest that preventive strategies may need to begin as early as stage 2 CKD.

Background: The metabolic abnormalities that occur secondary to chronic kidney disease (CKD) increase the risk of femoral neck fractures compared to the general population. The purpose of this study is to determine whether impaired renal function is an independent risk factor for complications after surgery for femoral neck fracture. Methods: The ACS-NSQIP database was reviewed for patients who underwent total hip arthroplasty, hemiarthroplasty and open reduction internal fixation (ORIF) for femoral neck fractures between 2007 and 2018. Patients were split into cohorts based on calculated estimated glomerular filtration rate. Demographic information, comorbidities, and 30-day complications were analysed with univariate and multivariate analyses using chi-square, Fischer’s exact and analysis of variance testing. Results: The total number of patients for the study was 163,717. Patients with CKD stage 4 and 5 had an increased rate of any complication (39.1 and 36.7% respectively) compared with higher eGFRs ( p  < 0.001). Similarly, 30-day mortality was increased at 6.0% and 6.7% for both stage 4 and 5 ( p  < 0.001). By multivariate regression, those with CKD Stage 4 and 5 were at increased risk for any complication compared to patients with a normal preoperative eGFR of 90–120 ( p  < 0.001). Conclusions: This study demonstrated that patients with CKD Stage 4 and 5 are at increased risks of all complications, including death, renal, pulmonary and thromboembolic disease. Therefore, these patients should be cared for from a multidisciplinary approach with close attention to postoperative medications and fall prevention to help mitigate the risk of complications in the immediate postoperative period.

Background:Objectives:To report the 10-year outcome of a cohort of patients with lupus nephritis (LN) treated with combined glucocorticoids with either mycophenolate mofetil (MMF) or tacrolimus (TAC) as induction in a randomized controlled trial (RCT).Methods:150 patients with active lupus nephritis were randomized to receive either MMF (2-3g/day) (N=76) or TAC (0.1-0.06mg/kg/day) (N=74) in combination with high-dose prednisolone (0.6mg/kg/day for 6-8 weeks and tapered) as induction therapy between 2005 and 2012. Complete renal (CR) or good partial renal responders were switched to azathioprine (AZA) (2mg/kg/day) for maintenance. We hereby report the 10-year outcomes of the patients in terms of renal flares (proteinuric/nephritic), renal function decline (drop in eGFR by ≥30% from baseline), development of chronic kidney disease (CKD) stage 4/5 (eGFR<30ml/min) and mortality. Factors affecting renal prognosis were studied by Cox regression analysis. Renal parameters (urine P/Cr ratio [uPCr], eGFR) at different time points from 6 to 24 months were studied for their predictive value of a poor renal prognosis by ROC analysis.Results:150 patients (92% women) with active LN were studied (ISN/RPS class III±V 36%; IVG/S±V 46%; pure V 19%). The mean age was 35.5±12.8 years and SLE duration was 50.2±62 months. The mean histological activity and chronicity score was 8.2±3.4 and 2.6±1.6, respectively. At baseline, 59(39%) patients were hypertensive, 62(41%) had active urinary casts, 112(75%) had microscopic hematuria and 67% patients had eGFR<90ml/min. As reported previously, the rate of complete renal response (CR) was 59% in the MMF and 62% in the TAC group (p=0.71). Maintenance therapy with AZA was given to 79% patients. After a follow-up of 118.2±42 months, proteinuric and nephritic renal flares occurred in 34% and 37% of patients treated initially with MMF and 53% and 30% in those treated with TAC, respectively. There was a total of 77 renal flares in 43 (57%) patients treated with MMF (0.11/patient-year) and 92 renal flares in 46 (62%) of patients treated with TAC (0.12/patient-year; p=0.44). The cumulative risk of having a renal flare of patients treated with MMF/AZA was 28% at 3 years, 42% at 5 years and 58% at 10 years, whereas the corresponding figures for patients treated with TAC/AZA was 32% at 3 years, 53% in 5 years and 66% in 10 years (p=0.43). For those who achieved CR after induction therapy, the mean time to first renal flare was 70.4±47.1 months in the MMF group and 65.2 ±50 months in the TAC group (p=0.61). The cumulative incidence of a composite outcome of decline of eGFR by ≥30%, development of CKD stage 4/5 or death at 5 and 10 years was 24% and 33%, respectively, in patients treated with MMF, and 17% and 33%, respectively, in those treated with TAC (p=0.90). Factors significantly associated with this outcome were first time lupus nephritis (HR 0.26[0.11-0.59]; p=0.001), uPCR at 6 months (HR 1.33[1.02-1.76]; p=0.04) and eGFR at 6 months (HR 0.98[0.97-0.997]; p=0.02). Exploratory ROC analysis demonstrated that an eGFR cut-off of 80ml/min (AUC 0.70; sensitivity 0.64, specificity 0.66) and uPCR cut-off of 0.75 (AUC 0.73; sensitivity 0.69, specificity 0.74) at month 18 best predicted CKD stage 4/5 or decline of eGFR by ≥30%.Conclusion:Long-term data of our RCT showed that TAC remained non-inferior to MMF as induction therapy of LN in terms of renal flares, renal function decline and mortality. Relapsed renal disease, lower eGFR and more proteinuria post-induction therapy were associated with a poorer outcome. An uPCR ≤0.75 and eGFR of >80ml/min at 18 months best predicted a better outcome at 10 years, and should be considered as a target for induction/consolidation therapy.Acknowledgments:NILDisclosure of Interests:None declared

Abstract Background and Aims Chronic kidney disease (CKD) is a chronic illness with important implications for the health of the population and for the commitment of resources by public health services. CKD staging makes it possible to assess the severity of the disease and its distribution in the population. The distribution of the stages of CKD diagnosed through hospitalization were analyzed using administrative database of the Local Health Authority of a province with a population of about 1 million inhabitants in northern Italy. Method Patients with hospital discharge with a diagnosis of CKD (ICD9CM 5851, 5852, 5853, 5854) in 2011- 2012 years, without dialysis treatment, neither transplantation procedure nor acute renal failure were selected. Demographic characteristics, comorbidities, dialysis treatment, drugs prescription and nephrological follow-up were investigated. This cohort of patients was examined over a 7-year period (2011-2017). Stage five was not considered to avoid possible misunderstanding with five D stage. Results 1808 patients diagnosed with CKD were extracted from the 2011-2017 administrative database; of these, 1267 had a diagnosis with the CKD stage specification. The distribution of 1267 patients in the CKD stages at the first hospital discharge was as follows: 7.4% stage 1, 30.9% stage 2, 42.3% stage 3, 19.3% stage 4. The 832 patients described in the study were still alive as of Jan. 1, 2013 while 435 (34.3%) died by Dec. 31, 2012. Until Dec. 31, 2017, 503 of the 832 patients died representing the 52.8% of stage 1 patients, 62% of stage 2 patients, 58.2% of stage 3 patients, 66.4% of stage 4 patients. Males were the most prevalent gender (58.5%), without any significant difference into CKD stages. Our patients have a fairly high age as can be seen from the table 1. The presence of co-morbidities was assessed either directly for the main risk factors or by the modified Charlson index (MCI) for CKD patients. The average value of the MCI is 3.8 ± 3.1 for all patients and 3.4 ±3.0 for stage 1, 4.1 ± 3.3 for stage 2, 3.7 ± 3.1 for stage 3, 3.7 ± 2.9 for stage 4, with maximum values of 12.0, 17.0, 16.0 and 14.0 respectively. About 40% of patients had diabetes mellitus, with the highest prevalence in stage 4 (49.3%) and the lowest in stage 1 (25%). Cardiovascular disease was distributed almost equally among all patients with a value between 82% in stage 1 and 86.3% in stage 4. Cancer were present in 26.3% of patients with similar values in all stages. Just about 9% of patients underwent dialysis treatment for achieving ESRD, with a percentage of 5.6% among patients in stage 1 and 17.1% among those in stage 4. Hemodialysis represented first choice treatment (86%) compared with peritoneal one (14%). Time from the diagnosis of CKD to the first dialysis was variable with an average of 3.4 ±1.7 years; the longest interval for patients in stage 1 (5.1±1.8) and the shortest (3.0 ±1.6) for patients in stage 4. The number of nephrological visits at renal units was analyzed for an assessment of the extent of follow-up and prevention upon reaching the ESRD (table2). More than 90% of patients had prescribed drugs antagonists of the renin angiotensin system, in all stages of CKD; other antihypertensive drugs (Ca channel blockers and peripheral vasodilators) had a similar prescription level. Anemia control drugs (ESA and iron) had an incremental prescription with stages of the disease from 51.4% in stage 1 to 74% in stage 4, similarly to Ca-P metabolism control drugs ranging from 44.4% in stage 1 to 67.8% in stage 4. Conclusion Correct staging of CKD is very important to assess the prognosis of patients, but the major determinants of outcome are comorbidities and age of the patients. The cohort examined has a high mortality rate, far higher than reported in the literature for CKD. It should be noted that the sample was identified by hospitalization for cardiovascular diseases more than 50% complicated by diabetes and hypertension, so death represents the main outcome and not ESRD.

Autosomal Dominant Polycystic Kidney

Background: Autosomal dominant polycystic kidney disease (ADPKD), a hereditary nephropathy, eventually leads to end-stage renal disease (ESRD), typically by mid-life. Objectives: The objective of this study was to assess real-world healthcare resource utilization and cost among commercially insured (COM) and Medicare Advantage (MAPD) ADPKD patients in addition to the cost profile by chronic kidney disease (CKD) stage. Methods: Patients diagnosed with ADPKD (two or more claims) with ≥30 days of continuous medical and pharmacy benefits and no evidence of autosomal recessive polycystic kidney disease were selected (Optum Research Database and Impact National Benchmarking Database: 1/1/06–8/31/12). Plan and patient paid healthcare costs and resource utilization per patient per month (PPPM) were described in total and by insurance type. CKD stage was established based on serum creatinine laboratory values or dialysis-related codes. Adjusted, CKD stage-specific costs were predicted for 4 years using regression models. Results: Of the 36,253,096 patients in the databases (1/1/06-8/31/12), 5,051 had evidence of ADPKD. Following exclusion criteria, 4,356 COM and 468 MAPD ADPKD patients remained. Total healthcare resource utilization and costs were high, and costs increased substantially from CKD stage 1–5. PPPM healthcare costs were 37% for ADPKD management and 52% for dialysis services. Predicted 4-year healthcare costs by CKD stage were $40,164 (stage 1), $33,397 (stage 2), $42,686 (stage 3), $148,402 (stage 4), and $207,548 (stage 5). Conclusions: Healthcare resource utilization and costs associated with ADPKD were substantial, irrespective of payer type, and primarily driven by CKD stage. Of the total healthcare costs, 88% were ADPKD- and dialysis-related. Most impactful was the spike in predicted cost when patients progressed from CKD stage 3 to stage 4 (by 348%) after multivariate adjustment. These stage 4–associated costs are primarily due to ultimate progression into stage 5 and ESRD within the 4-year time frame.

Background: Many drugs should be avoided or require dose-adjustment in chronic kidney disease (CKD). Previous estimates of potentially inappropriate prescribing rates have been based on data on a limited number of drugs and mainly in secondary care settings. Aim: To determine the prevalence of contraindicated and potentially inappropriate primary care prescribing in a complete population of people with CKD. Method: Cross-sectional study of prescribing patterns in a complete geographical population of people with CKD defined using laboratory data. Drugs were organised by British National Formulary advice. Contraindicated (CI) drugs: “avoid”. Potentially high risk (PHR) drugs: “avoid if possible”. Dose inappropriate (DI) drugs: dose exceeded recommended maximums. Results: 28,489 people with CKD were included in analysis, of whom 70.0% had CKD 3a, 22.4% CKD 3b, 5.9% CKD 4, and 1.5% CKD 5. 3.9% (95%CI 3.7-4.1) of people with CKD stages 3a-5 were prescribed one or more CI drug, 24.3% (95%CI 23.8-24.8) PHR drug, and 15.2% (95% CI 14.8-15.62) DI drug. CI drugs differed in prevalence by CKD stage, and were most commonly prescribed in CKD stage 4 with a prevalence of 36.0% (95%CI 33.7–38.2). PHR drugs were commonly prescribed in all CKD stages ranging from 19.4% (95%CI 17.6-21.3) in stage 4 to 25.1% (95%CI 24.5–25.7) in stage 3b. DI drugs were most commonly prescribed in stage 4, 26.4% (95%CI 24.3-28.6). Conclusion: Potentially inappropriate prescribing is common at all stages of CKD. Development and evaluation of interventions to improve prescribing safety in this high-risk populations are needed.

Abstract Background Anemia is a severe complication of chronic kidney disease (CKD) that is seen in more than 80% of patients with impaired renal function. Although there are many mechanisms involved in the pathogenesis of anemia of renal disease, the primary cause is the inadequate production of erythropoietin by the damaged kidneys. Aim of the work to assess hepcidin level in non dialysis patients (CKD stage 4 &5) treated from Hepatitis C virus and its relation to iron parameters. Patients and Methods This study was conducted on 20 CKD patients (stage 4 and 5) treated from hepatitis C virus. All candidates included in this study subjected to careful history taking, full clinical examination and investigations (including complete blood count, renal chemistry, HCVAb, serum iron, total iron binding capacity, TSAT%, ferritin and hsCRP. Serum hepcidin was analyzed by ELISA technique. Results Serum hepcidin was 26.35±7.26; 40% in stage III, 37.8% in stage IV and 22.2% in stage V. There was statistically significant difference between GFR stages according to Hb., Drug intake ACE inhibitor/ARB, Plt., Creatinine, BUN, Iron, TIBC, Ferritin, T SAT%, CRP and Serum Hepcidin. We showed significant correlations between serum hepcidin and TIC, Iron, TIBC, Ferritin and TSAT%. Conclusion Median hepcidin value is elevated in nondialysis CKD patients due to increased inflammation and decreased clearance of hepcidin. Furthermore, iron status modifies serum hepcidin level and its association with Hb. Increased hepcidin level leads to iron-restricted erythropoiesis and recombinant human EPO (rhEPO) resistance by inhibiting iron absorption from gut and iron recycling from macrophages. Hence, elevated hepcidin can predict need for parenteral iron to overcome hepcidin-mediated iron-restricted erythropoiesis and need for relatively higher rhEPO doses to suppress hepcidin.

Background: Chronic kidney disease (CKD) patients have a higher cardiovascular (CV) disease and mortality risk, elevated triglycerides (TG), and decreased high density lipoproteins (HDL). Post-hoc analysis of trials examining use of fibrate (Fib) or niacin (Nia) therapy in lowering CV outcome risk have failed to show benefit in mild to moderate kidney disease. These analyses were criticized for their study design or small sample size. We sought to examine if Fib or Nia use is associated with lower mortality risk in US veterans across CKD stages. Methods: In a retrospective cohort analysis, we identified male veterans who initiated Fib or Nia, with a high TG ≥150 mg/dL or low HDL ≤40 mg/dL between 2004-2014, and matched them on CKD stage and TG and HDL levels to unexposed men. We examined the association of Fib or Nia use (ref: unexposed) with 12-month all-cause mortality risk across CKD stage strata using an adjusted Cox proportional hazards model. Propensity scores (PS) included baseline demographics, comorbidities and lab measures and high-dimensional propensity scores (HDPS) included over 100 covariates for each drug and stage analysis. PS and HDPS analyses included score adjustment and matching. Results: The cohort had a mean±SD age of 64±12 years, and 30% had CKD stage 3A and higher. There were 69,295 Fib, 87,727 Nia, and 114,411 unexposed patients, respectively. Patient characteristics were similar across drug groups within each CKD stage. With covariate adjustment, both Fib and Nia were associated with a lower death risk compared to unexposed men in lower CKD stages (Figure A and B). Among those with CKD stage 4/5, Fib and Nia were associated with a higher death risk (HR[95%CI]: 1.43[1.15, 1.78] and 1.17[0.97,1.40], respectively). Those on Fib or Nia and in end-stage renal disease had a null association with mortality. Associations were similar for each CKD stage in PS and HDPS analyses, yet Fib and Nia were no longer associated with a lower death risk for CKD stage 3A and 3B patients. Conclusion: Mortality associations of Fib and Nia among male veterans with high TG and low HDL varied across CKD stage, where CKD stage 4/5 patients had a higher mortality risk, even in PS and HDPS analyses. While covariate balance was met, further studies are needed to examine the mechanisms for this higher observed risk in late-stage CKD patients.

Abstract Background Guidelines indicate that a low-protein diet (LPD) delays dialysis in severe chronic kidney disease (CKD). We assessed the value of these guidelines by performing a retrospective analysis in our renal clinical practice. Methods The analysis was performed from 1 January 2010 to 31 March 2018 in 299 CKD Stage 4 patients followed for 70 months in collaboration with a skilled nutritionist. The patients included 43 patients on a controlled protein diet (CPD) of 0.8 g/kg/day [estimated glomerular filtration rate (eGFR) 20–30 mL/min/1.73 m2 body surface (b.s.)], 171 patients on an LPD of 0.6 g/kg/day and 85 patients on an unrestricted protein diet (UPD) who were not followed by our nutritionist (LPD and UPD, eGFR &lt;20 mL/min/1.73 m2 b.s.). Results eGFR was higher in CPD patients than in UPD and LPD patients (21.9 ± 7.4 mL/min/1.73 m2 versus 17.6 ± 8.00 mL/min/1.73 m2 and 17.1 ± 7.5 mL/min/1.73 m2; P = 0.008). The real daily protein intake was higher in UPD patients than in LPD and CDP patients (0.80 ± 0.1 g/kg/day versus 0.6 ± 0.2 and 0.63 ± 0.2 g/kg/day; P = 0.01). Body mass index (BMI) was stable in the LPD and CPD groups but decreased from 28.5 ± 4.52 to 25.4 ± 3.94 kg/m2 in the UPD group (P &lt; 0.001). The renal survival of UPD, LPD and CPD patients was 47.1, 84.3 and 90.7%, respectively, at 30 months (P &lt; 0.001), 42.4, 72.0 and 79.1%, respectively, at 50 months (P &lt; 0.001) and 42.4, 64.1 and 74.4%, respectively, at 70 months (P &lt; 0.001). The LPD patients started dialysis nearly 24 months later than the UPD patients. Diet was an independent predictor of dialysis [−67% of RR reduction (hazard ratio = 0.33; confidence interval 0.22–0.48)] together with a reduction in BMI. Conclusions An LPD recommended by nephrologists in conjunction with skilled dietitians delays dialysis and preserves nutritional status in severe CKD.
