Patients were randomly assigned to one of four groups: activated bamboo charcoal (ABC), probiotics, ABC with probiotics, or standard treatment for 3 months.<\/jats:p>\n            <\/jats:sec>\n            <jats:sec>\n               <jats:title>Results<\/jats:title>\n               <jats:p>A total of 46 patients were enrolled (mean age 66.7 \u00b1 11.5 years, 71.7% male). The ABC and ABC with probiotics groups showed a significant reduction in serum levels of the uremic toxins trimethylamine N-oxide (TMAO), p-cresyl sulfate (PCS), indoxyl sulfate (IS), and phenyl sulfate (PS) after 3 months of treatment (all <jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.05). There was a particularly pronounced decrease in the percentage of IS in both the ABC group (\u221223.9 \u00b1 28.9% <jats:italic>vs<\/jats:italic>. 33.9 \u00b1 63.4%, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.005) and the ABC with probiotics group (\u221229.3 \u00b1 30.6% <jats:italic>vs<\/jats:italic>. 33.9 \u00b1 63.4%, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.009). The eGFR change ratio also significantly improved in the ABC group compared to the control group (4.6 \u00b1 10.2% <jats:italic>vs<\/jats:italic>. \u22128.6 \u00b1 12.5%, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.011). However, the probiotics group did not exhibit a similar reduction in uremic toxins or an improvement in the eGFR.<\/jats:p>\n            <\/jats:sec>\n            <jats:sec>\n               <jats:title>Conclusion<\/jats:title>\n               <jats:p>This study suggested that ABC significantly reduced uremic toxins and might have potential in improving eGFR in CKD stage 3 patients over a 3-month period. These findings suggest a potential protective effect of ABC on kidney function, highlighting the need for further large-scale, long-term randomized controlled trials to confirm these results.<\/jats:p>\n
