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 <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 < 0.001). The renal survival of UPD, LPD and CPD patients was 47.1, 84.3 and 90.7%, respectively, at 30 months (P < 0.001), 42.4, 72.0 and 79.1%, respectively, at 50 months (P < 0.001) and 42.4, 64.1 and 74.4%, respectively, at 70 months (P < 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.

Background: Several clinical studies have shown that a low protein diet in patients with Chronic Kidney Disease (CKD), delays the natural progression of the end stage renal disease (ESRD) and the necessary treatment of chronic dialysis.Objective: The aim of this study is to estimate the cost-effectiveness of a low protein diet compared with no dietary treatment in patients with CKD stage 4 and 5 after 2, 3, 5 and 10 years.Method: A Markov model was developed to estimate costs and QALYs associated with low protein diet versus no treatment for patients with CKD stage 4-5. The transition probability was estimated on data from seven studies which determined the efficacy of low protein diets in delaying the need to start maintenance dialysis. The Quality Adjusted Life Years (QALYs) scores used were estimated with the Time Trade Off technique. The annual cost of dialysis per patient was estimated to be approximately €34,072. The costs of a low-protein diet was €1,440 per patient per year in the Lazio Region (conservative assumptions). Results: Treatment with a low-protein diet was more effective in terms of QALYs: the difference was always in favour of dietary treatment from a 0.09 QALYS after the first two years, 0.16 after three years, 0.36 after five years and up to a differential of 0.93 year after the first 10 years of treatment. In terms of cost-effectiveness, the dietary treatment was always dominant in all intervals considered. The dominance is due to the fact that the treatment is more effective in terms of QALYs and at the same time is less expensive.Conclusion: The results of these simulations indicate that the treatment of CKD patients with a low protein diet is cost effective relative to no treatment in an Italian setting. Further studies should test this model in other countries with different dialysis costs and dietary support.Key words: chronic kidney disease, low-protein diet, cost-effectiveness of a low protein diet

Abstract Background and Aims Dietary protein restriction is rediscussed as mainstay approach in advanced Chronic Kidney Disease (CKD), both in diabetics and non-diabetics to defer renal replacement therapy (RRT), mainly by better metabolic control; improvements in mineral bone disorders (MBD) were also suggested, but less studied in Diabetic Kidney Disease (DKD). An unicentric prospective interventional trial aimed to assess the effects of ketoanalogue-supplemented low protein diet (sLPD) on proteinuria and CKD progression (data already presented). The parameters of MBD were also evaluated. Method Adult diabetic patients (452) with stable CKD stage 4+, proteinuria>3g/g creatininuria and SGA A were enrolled in a run-in phase (3 mo), with LPD (0.6g/kg dry ideal bw). Those who proved adherent (92, 64% males, median age 55.7 yrs, 65% on insulin) received sLPD (Ketosteril®, 1 tablet/10kg) for 12mo. Monitoring and treatment followed the Best Practice Guidelines. The primary endpoint was proteinuria during intervention as compared to pre-enrolment. Serum levels of calcium, phosphates and iPTH were considered to assess MBD. Nutrition, inflammation (SGA, BMI, serum albumin, CRP) and compliance were safety parameters. Results In patients with advanced DKD and severe proteinuria, sLPD was associated with a 69 (63; 82) % reduction in proteinuria (data presented). Significant amelioration in MBD was noted: serum levels of calcium and phosphates were significantly ameliorated at the end of the study as compared to enrolment - 4.3 (4.2-4.9) vs 3.2 (3.1-3.5) mg/dL and 5.4 (4.9-6.1) vs 8.2 (7.8-8.9) mg/dL, respectively. Serum iPTH significantly decreased: 185 (168-212) vs 375 (354-585) pg/mL. The need for calcium supplementation decreased: 6.5 (6.0-6.7) vs 7.0 (6.8-7.3) g/day. Vitamin D was required by only 35% vs 65% of patients. Nutritional status was preserved and dietary compliance was very good throughout the study. Conclusion In patients with advanced DKD ketoanalogue supplemented low protein diet seems to be effective and safe as part of MBD management.

Chronic kidney disease (CKD) affects >10% of the adult population. Each year approximately 120,000 Americans develop end-stage kideny disease and initiate dialysis, which is costly and associated with functional impairments, worse health-related quality of life, and high early-mortality rates exceeding 20% in the first year. Recent declarations by the World Kidney Day and the U.S. Government Executive Order seek to implement strategies that reduce the burden of kidney failure by slowing CKD progression and controlling uremia without dialysis. Pragmatic dietary interventions may have a role in improving CKD outcomes and preventing or delaying dialysis initiation. Evidence suggests that a patient-centered plant-dominant low-protein diet (PLADO) of 0.6-0.8 g/kg/day comprised of >50% plant-based sources, administered by dietitians trained in non-dialysis CKD care, can be promising. The scientific premise of the PLADO is based on the observations that high protein diets with high meat intake are not only associated with higher cardiovascular disease risk but also higher CKD incidence and faster CKD progression due to increased intraglomerular pressure and glomerular hyperfiltration. Meat intake increases production of nitrogenous end-products, worsens uremia, and may increase the risk of hyperkalemia, given constipation from the typical low fiber intake. Plant-dominant, fiber-rich, low-protein diet may lead to favorable alterations in the gut microbiome, which can modulate uremic toxin generation and slow CKD progression, along with reducing cardiovascular risk in CKD patients. PLADO is a heart-healthy, safe, flexible, and feasible diet that could be the centerpiece of a conservative and preservative CKD-management strategy that challenges the prevailing dialysis-centered paradigm.

The effects of ketoanalogues (KA) on chronic kidney disease (CKD) deterioration have not yet been fully confirmed. To strengthen the evidence of the role of KA in CKD, PubMed and Embase were searched for studies published through February 2019. Effect sizes from ten randomized control trials (RCTs) and two non-RCTs comprising a total of 951 patients were pooled and analyzed. A restricted protein diet supplemented with ketoanalogues (RPKA) was found to significantly delay the progression of CKD (p = 0.008), particularly in patients with an estimated glomerular filtration rate (eGFR) > 18 mL/min/1.73 m2 (p < 0.0001). No significant change in eGFR was found when comparing a very-low-protein diet and a low-protein diet (p = 0.10). In addition, compared with the placebo, RPKA did not cause malnutrition (albumin: p = 0.56; cholesterol: p = 0.50). Moreover, RPKA significantly decreased phosphorous levels (p = 0.001), increased calcium levels (p = 0.04), and decreased parathyroid hormone (PTH) levels (p = 0.05) in patients with eGFR < 18 mL/min/1.73 m2. In conclusion, RPKA could slow down the progression of CKD in patients with eGFR > 18 mL/min/1.73 m2 without causing malnutrition and reverse CKD-MBD in patients with eGFR < 18 mL/min/1.73 m2.

Abstract Background The prevalence of left atrial enlargement (LAE) and fragmented QRS (fQRS) diagnosed using ECG criteria in patients with severe chronic kidney disease (CKD) is unknown. Furthermore, there is limited data on predicting new-onset atrial fibrillation (AF) with LAE or fQRS in this patient group. Methods We enrolled 165 consecutive non-dialysis patients with CKD stage 4–5 without prior AF diagnosis between 2013 and 2017 in a prospective follow-up cohort study. LAE was defined as total P-wave duration ≥120 ms in lead II ± > 1 biphasic P-waves in leads II, III or aVF; or duration of terminal negative portion of P-wave > 40 ms or depth of terminal negative portion of P-wave > 1 mm in lead V1 from a baseline ECG, respectively. fQRS was defined as the presence of a notched R or S wave or the presence of ≥1 additional R waves (R’) or; in the presence of a wide QRS complex (> 120 ms), > 2 notches in R or S waves in two contiguous leads corresponding to a myocardial region, respectively. Results Mean age of the patients was 59 (SD 14) years, 56/165 (33.9%) were female and the mean estimated glomerular filtration rate was 12.8 ml/min/1.73m2. Altogether 29/165 (17.6%) patients were observed with new-onset AF within median follow-up of 3 [IQR 3, range 2–6] years. At baseline, 137/165 (83.0%) and 144/165 (87.3%) patients were observed with LAE and fQRS, respectively. Furthermore, LAE and fQRS co-existed in 121/165 (73.3%) patients. Neither findings were associated with the risk of new-onset AF within follow-up. Conclusion The prevalence of LAE and fQRS at baseline in this study on CKD stage 4–5 patients not on dialysis was very high. However, LAE or fQRS failed to predict occurrence of new-onset AF in these patients.

The present study demonstrated that autophagy/mitophagy was increased and inflammation was aggravated in skeletal muscle in chronic kidney disease (CKD) rats. A low-protein diet (LPD) supplemented with ketoacids (KA) improved the loss in muscle mass and blocked the activation of autophagy/mitophagy and inflammation in those rats.
