The Role of Dietary Fiber Supplementation in Regulating Uremic Toxins in Patients With Chronic Kidney Disease: A Meta-Analysis of Randomized Controlled Trials

Gut-derived uremic toxins, including indoxyl sulfate (IS) and p-cresyl sulfate (PCS), are waste products that accumulate in the body due to decreased clearance by the failing kidneys. These accumulated uremic toxins are a risk factor associated with cardiovascular disease, progression of kidney dysfunction, mineral bone disorders, and increased mortality in patients with CKD. This meta-analysis showed that dietary fiber supplementation could decrease IS and PCS levels in patients with CKD.

Causal effects of physical activity or sedentary behaviors on kidney function: an integrated population-scale observational analysis and Mendelian randomization study

The health benefits of exercise and regular physical activity are vast. Using Mendelian randomization (MR) to assess causality, this study found that “the genetic predisposition to a higher degree of physical activity was associated with a lower risk of CKD and a higher eGFR, while the genetically predicted television watching duration was associated with a higher risk of CKD and a lower eGFR.”

Prevalence of Inflammatory Bowel Disease and Celiac Disease in Patients with IgA Nephropathy over Time

Poor gut health and a lack of intestinal wall integrity is linked to many diseases, including IgA nephropathy (IgAN). The results of this Finnish study showed an increase in the prevalence of inflammatory bowel disease (IBD) in patients with newly diagnosed IgAN over a 36-year period.
