Article The Gut-Kidney Axis in Calcium Oxalate Nephrolithiasis: Nutritional and Microbial Insights(Kare Publ, 2026) Sener, Goksel; Marzi, Mahdi; Sener, Tarik EmreCalcium oxalate (CaOx) nephrolithiasis is the most common type of kidney stone disease worldwide. Recent studies show that its development cannot be explained solely by renal solute handling; instead, it reflects a broader interaction between dietary habits, the intestinal microbiota, and host metabolic responses. Intestinal absorption of calcium and oxalate-two central drivers of lithogenesis-is shaped by both microbial composition and dietary patterns. Although Oxalobacter formigenes was initially regarded as the main oxalate-degrading organism, newer studies indicate that a wider disturbance of the gut microbiota, especially the loss of short-chain fatty acid (SCFA)-producing species, may increase susceptibility to stone formation. In this review, nutritional, microbial, and mechanistic evidence is brought together to examine how diet-particularly salt, animal protein, calcium, oxalate, fruits, vegetables, and water intake-modulates the gut-kidney axis. Diets high in salt or animal protein tend to shift the microbiota toward more pro-inflammatory and acidogenic profiles, while fiber-rich, plant-based diets and adequate hydration appear to support microbial diversity, SCFA production, and epithelial barrier integrity. Probiotic and synbiotic interventions have also gained attention as potential strategies to reduce stone recurrence by targeting gut microbial function. Taken together, current findings suggest that the gut-kidney axis is a dynamic metabolic link between diet, microbial ecology, and renal physiology. Future studies combining multi-omics methods with personalized nutritional approaches may help develop more effective microbiota-based prevention and treatment strategies for CaOx nephrolithiasis.Article Citation - WoS: 7Citation - Scopus: 6The Potential Role of Boron in the Modulation of Gut Microbiota Composition: an in Vivo Pilot Study(Mdpi, 2024) Senturk, Nermin Basak; Kasapoglu, Burcu; Sahin, Eray; Ozcan, Orhan; Ozansoy, Mehmet; Ozansoy, Muzaffer Beyza; Sahin, FikrettinBackground/Objectives: The role of the gut microbiome in the development and progression of many diseases has received increased attention in recent years. Boron, a trace mineral found in dietary sources, has attracted interest due to its unique electron depletion and coordination characteristics in chemistry, as well as its potential role in modulating the gut microbiota. This study investigates the effects of inorganic boron derivatives on the gut microbiota of mice. Methods: For three weeks, boric acid (BA), sodium pentaborate pentahydrate (NaB), and sodium perborate tetrahydrate (SPT) were dissolved (200 mg/kg each) in drinking water and administered to wild-type BALB/c mice. The composition of the gut microbiota was analyzed to determine the impact of these treatments. Results: The administration of BA significantly altered the composition of the gut microbiota, resulting in a rise in advantageous species such as Barnesiella and Alistipes. Additionally, there was a decrease in some taxa associated with inflammation and illness, such as Clostridium XIVb and Bilophila. Notable increases in genera like Treponema and Catellicoccus were observed, suggesting the potential of boron compounds to enrich microbial communities with unique metabolic functions. Conclusions: These findings indicate that boron compounds may have the potential to influence gut microbiota composition positively, offering potential prebiotic effects. Further research with additional analyses is necessary to fully understand the interaction between boron and microbiota and to explore the possibility of their use as prebiotic agents in clinical settings.
