    Assessing Global Kidney Nutrition Care
    (Wolters Kluwer, 2022) Wang, Angela Yee-Moon; Okpechi, Ikechi G.; Ye, Feng; Kovesdy, Csaba P.; Brunori, Giuliano; Burrowes, Jerrilynn D.; Campbell, Katrina; Damster, Sandrine; Fouque, Denis; Friedman, Allon N.; Garibotto, Giacomo; Guebre-Egziabher, Fitsum; Harris, David; Iseki, Kunitoshi; Jha, Vivekanand; Jindal, Kailash; Kalantar-Zadeh, Kamyar; Kistler, Brandon; Kopple, Joel D.; Kuhlmann, Martin; Lunney, Meaghan; Mafra, Denise; Malik, Charu; Moore, Linda W.; Price, S.

    Background and objectives: Nutrition intervention is an essential component of kidney disease management. This study aimed to understand current global availability and capacity of kidney nutrition care services, interdisciplinary communication, and availability of oral nutrition supplements. Design, setting, participants, & measurements: The International Society of Renal Nutrition and Metabolism (ISRNM), working in partnership with the International Society of Nephrology (ISN) Global Kidney Health Atlas Committee, developed this Global Kidney Nutrition Care Atlas. An electronic survey was administered among key kidney care stakeholders through 182 ISN-affiliated countries between July and September 2018. Results: Overall, 160 of 182 countries (88%) responded, of which 155 countries (97%) answered the survey items related to kidney nutrition care. Only 48% of the 155 countries have dietitians/renal dietitians to provide this specialized service. Dietary counseling, provided by a person trained in nutrition, was generally not available in 65% of low-/lower middle-income countries and "never" available in 23% of low-income countries. Forty-one percent of the countries did not provide formal assessment of nutrition status for kidney nutrition care. The availability of oral nutrition supplements varied globally and, mostly, were not freely available in low-/lower middle-income countries for both inpatient and outpatient settings. Dietitians and nephrologists only communicated "sometimes" on kidney nutrition care in ≥60% of countries globally. Conclusions: This survey reveals significant gaps in global kidney nutrition care service capacity, availability, cost coverage, and deficiencies in interdisciplinary communication on kidney nutrition care delivery, especially in lower-income countries.

    The International Society of Renal Nutrition and Metabolism Commentary on the National Kidney Foundation and Academy of Nutrition and Dietetics KDOQI Clinical Practice Guideline for Nutrition in Chronic Kidney Disease
    (Elsevier, 2021) Kistler, Brandon M.; Moore, Linda W.; Benner, Debbie; Biruete, Annabel; Boaz, Mona; Brunori, Giuliano; Chen, Jing; Drechsler, Christiane; Guebre-Egziabher, Fitsum; Hensley, Mary Kay; Iseki, Kunitoshi; Kovesdy, Csaba P.; Kuhlmann, Martin K.; Saxena, Anita; Wee, Pieter Ter; Brown-Tortorici, Amanda; Garibotto, Giacomo; Price, S.

    The Academy of Nutrition and Dietetics and the National Kidney Foundation collaborated to provide an update to the Clinical Practice Guidelines (CPG) for nutrition in chronic kidney disease (CKD). These guidelines provide a valuable update to many aspects of the nutrition care process. They include changes in the recommendations for nutrition screening and assessment, macronutrients, and targets for electrolytes and minerals. The International Society of Renal Nutrition and Metabolism assembled a special review panel of experts and evaluated these recommendations prior to public review. As one of the highlights of the CPG, the recommended dietary protein intake range for patients with diabetic kidney disease is 0.6-0.8 g/kg/day, whereas for CKD patients without diabetes it is 0.55-0.6 g/kg/day. The International Society of Renal Nutrition and Metabolism endorses the CPG with the suggestion that clinicians may consider a more streamlined target of 0.6-0.8 g/kg/day, regardless of CKD etiology, while striving to achieve intakes closer to 0.6 g/kg/day. For implementation of these guidelines, it will be important that all stakeholders work to detect kidney disease early to ensure effective primary and secondary prevention. Once identified, patients should be referred to registered dietitians or the region-specific equivalent, for individualized medical nutrition therapy to slow the progression of CKD. As we turn our attention to the new CPG, we as the renal nutrition community should come together to strengthen the evidence base by standardizing outcomes, increasing collaboration, and funding well-designed observational studies and randomized controlled trials with nutritional and dietary interventions in patients with CKD.

    New Insights Into Dietary Approaches to Potassium Management in Chronic Kidney Disease
    (Elsevier, 2023) Sumida, Keiichi; Biruete, Annabel; Kistler, Brandon M.; Khor, Ban-Hock; Ebrahim, Zarina; Giannini, Rossella; Sussman-Dabach, Elizabeth J.; Avesani, Carla Maria; Chan, Maria; Lambert, Kelly; Wang, Angela Yee-Moon; Clegg, Deborah J.; Burrowes, Jerrilynn D.; Palmer, Biff F.; Carrero, Juan-Jesus; Kovesdy, Csaba P.; Nutrition and Dietetics, School of Health and Human Sciences
    Potassium disorders are one of the most common electrolyte abnormalities in patients with chronic kidney disease (CKD), contributing to poor clinical outcomes. Maintaining serum potassium levels within the physiologically normal range is critically important in these patients. Dietary potassium restriction has long been considered a core strategy for the management of chronic hyperkalemia in patients with CKD. However, this has been challenged by recent evidence suggesting a paradigm shift toward fostering more liberalized, plant-based dietary patterns. The advent of novel potassium binders and an improved understanding of gastrointestinal processes involved in potassium homeostasis (e.g., gastrointestinal potassium wasting) may facilitate a paradigm shift and incorporation of heart-healthy potassium-enriched food sources. Nevertheless, uncertainty regarding the risk-benefit of plant-based diets in the context of potassium management in CKD remains, requiring well-designed clinical trials to determine the efficacy of dietary potassium manipulation toward improvement of clinical outcomes in patients with CKD.

    Nutritional and Dietary Management of Chronic Kidney Disease Under Conservative and Preservative Kidney Care Without Dialysis
    (Elsevier, 2023) Rhee, Connie M.; Wang, Angela Yee-Moon; Biruete, Annabel; Kistler, Brandon; Kovesdy, Csaba P.; Zarantonello, Diana; Ko, Gang Jee; Piccoli, Giorgina Barbara; Garibotto, Giacomo; Brunori, Giuliano; Sumida, Keiichi; Lambert, Kelly; Moore, Linda W.; Han, Seung Hyeok; Narasaki, Yoko; Kalantar-Zadeh, Kamyar; Medicine, School of Medicine
    While dialysis has been the prevailing treatment paradigm for patients with advanced chronic kidney disease (CKD), emphasis on conservative and preservative management in which dietary interventions are a major cornerstone have emerged. Based on high-quality evidence, international guidelines support the utilization of low-protein diets as an intervention to reduce CKD progression and mortality risk, although the precise thresholds (if any) for dietary protein intake vary across recommendations. There is also increasing evidence demonstrating that plant-dominant low-protein diets reduce the risk of developing incident CKD, CKD progression, and its related complications including cardiometabolic disease, metabolic acidosis, mineral and bone disorders, and uremic toxin generation. In this review, we discuss the premise for conservative and preservative dietary interventions, specific dietary approaches used in conservative and preservative care, potential benefits of a plant-dominant low-protein diet, and practical implementation of these nutritional strategies without dialysis.

    Targeting the Gut Microbiota in Kidney Disease: The Future in Renal Nutrition and Metabolism
    (Elsevier, 2023) Lambert, Kelly; Rinninella, Emanuele; Biruete, Annabel; Sumida, Keiichi; Stanford, Jordan; Raoul, Pauline; Mele, Maria Cristina; Wang, Angela Yee-Moon; Mafra, Denise; Medicine, School of Medicine
    There is increasing interest in the therapeutic potential of manipulating the gut microbiome of patients with chronic kidney disease (CKD). This is because there is a substantial deviation from a balanced gut microbiota profile in CKD, with many deleterious downstream effects. Nutritional interventions such as plant-based diets with reduced animal protein intake and the use of probiotics, prebiotics, and synbiotics may alter the microbiome. This article aims to briefly describe what is known about the gut microbiome in patients with CKD, factors contributing to gut dysbiosis, and outline important evidence gaps. Future potential therapies, including restoring the microbiota with food and microbiota-based and metabolomic-based therapies, are also discussed.
