Given the adverse side effect profiles and variable efficacy of these medications, there is an urgent need to identify novel and safe therapies to treat nephrotic syndrome in children. Stimulation of the vagus nerve, which can be activated non invasively by transcutaneous auricular vagus nerve stimulation (taVNS), has immunomodulatory effects mediated by the inflammatory reflex and spleen. taVNS has become a therapy of interest for treating chronic immune mediated illnesses. The aims of the study are (1) To determine the feasibility of protocol implementation and tolerability of taVNS in the treatment of nephrotic syndrome in children (2) To establish proof-of-concept and generate statistical estimates of variance parameters and effect sizes for treatment response outcomes in children with nephrotic syndrome randomized to taVNS therapy compared with sham therapy (3) To investigate the effects of taVNS on inflammatory markers in children with nephrotic syndrome.",[121,122,123],"Nephrotic Syndrome in Children","Minimal Change Disease","Focal Segmental Glomerulosclerosis",[125,126,127],"vagus nerve stimulation","pediatric","nephrology","2026-04-14",{"date":130,"type":131},"2026-04-15","ACTUAL",{"date":133,"type":131},"2023-01-05",{"date":135,"type":115},"2027-08-01",{"name":5,"class":6},2]
