What the trial is, and whether it could suit you

Children with steroid resistant nephrotic syndrome (SRNS) are exposed to prolonged courses of immunosuppressant medications. 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 noninvasively 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 o
