Introduction: Gut dysbiosis is a common feature in cardiorenal syndrome, and it is linked to increased uremic toxins, like trimethylamine-n-oxide (TMAO), which are involved with inflammation and cardiovascular mortality. Brazil nut (typical Brazilian seed) has anti-inflammatory and antioxidant properties, but there is no evidence of the effects of gut microbiota modulation and reduction of uremic toxins. Objective: To assess the impact of Brazil nut consumption on TMAO levels and inflammation markers in a patient with cardiorenal syndrome. Methods: Acoronary artery disease patient(66 years and BMI, 26 kg/m2),stage-3 of CKD (eGFR 36 mL/min), receivedone Brazil nut per day for three months. Results: TMAO plasma levels and NF-κB mRNA expression were reduced, and glutathione peroxidase (GPx) activity increased after this intervention. Conclusion: Brazil nut prescription may be a promising strategy to mitigate complications related tothe cardiorenal syndrome. This case supports the concept of “Food as medicine” targeting the uremic phenotype in cardiorenal syndrome.
