Special Issue Information

Dear Colleagues,

The purpose of this Special Issue, “Nutritional Epidemiology of Chronic Kidney Disease and Complications”, is to explore the most up-to-date available evidence on the role of nutrition in chronic kidney disease and complications.

The conventional diet for chronic kidney disease includes low protein, low salt, and potassium restriction. However, there has been a major reassessment in recent years. The perspective on minerals and vitamins is also changing dramatically, with an emphasis on the importance of the quality, as well as the quantity, of various nutrients, such as magnesium, zinc and iron, in addition to potassium.

This Special Issue will include original research works and literature reviews that further explore the changing views of diet and nutrition for chronic kidney disease and complications.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nutrients is an international peer-reviewed open access semimonthly journal published by MDPI.

Background: Diabetic kidney disease (DKD) affects 20–50% of individuals with diabetes. The aim of this review was to identify interventions that positively influence the gut microbiota in DKD. Methods: Identification of relevant studies was conducted via a systematic search of databases and registers using the PRISMA guidelines. This review examined the relevant literature published up to 5 January 2025, using a systematic search in PubMed and Scopus. The search was conducted with combinations of keywords including DKD and therapy, supplementation and gut microbiota, and supplementation or probiotics or fecal microbiota transplant. The initial search fielded 132 results from PubMed and 72 from Scopus, which was narrowed to 135 relevant studies. The exclusion criteria included non-English language studies, letters to the editor, and conference abstracts. Eligible studies were independently assessed by a minimum of three authors, with discrepancies resolved through consensus. Results: Gut microbiota-targeted interventions, including probiotics, synbiotics, and dietary modifications, show promise in modulating the gut microbiota, but evidence specific to DKD remains limited. Some natural food components such as polyphenols and anthocyanins modulate the composition of the gut microbiota translocation of uremic toxins, which slows down the progression of diabetic kidney disease. In animal models, fecal microbiota transplantation (FMT) has shown positive effects in regulating dysbiosis and beneficial effects in chronic kidney disease, but studies involving humans with DKD are insufficient. Conclusions: Lactobacillus and Bifidobacterium strains, administered at doses ranging from 0.6 to 90 billion CFU, may help lower urea and creatinine levels, but outcomes vary by disease stage, duration of therapy, and amount used. High-fiber diets (>10.1 g/1000 kcal/day) and supplements such as resistant starch and curcumin (400–1500 mg/day) may reduce uremic toxins through gut microbiota modulation and reduction in oxidative stress. The effect of sodium butyrate requires further human studies. Full article
