Rituximab and Targeted Nursing for Pediatric Nephrotic Syndrome

Nephrotic syndrome in children, particularly steroid-dependent (SDNS) or frequently relapsing (FRNS) types, poses significant treatment challenges. While glucocorticoids are initial mainstays, second-line immunosuppressants like tacrolimus or rituximab are often required. Rituximab, a monoclonal antibody targeting CD20 on B-lymphocytes, has shown promise. Targeted nursing care, a patient-centered approach involving joint goal-setting and personalized interventions, aims to improve adherence and overall well-being. This study aimed to evaluate the synergistic effect of rituximab therapy combined with a structured targeted nursing care program compared to tacrolimus with the same targeted nursing care. A total of 91 pediatric patients (aged 6-15 years) with SDNS or FRNS were enrolled from January 2021 to June 2023. They were randomized into a study group (n=46, rituximab + targeted nursing) and a control group (n=45, oral tacrolimus + targeted nursing). Both groups received baseline glucocorticoid therapy. The study group received intravenous rituximab (375 mg/m² weekly for 12 weeks). The control group received oral tacrolimus (0.05-0.1 mg/kg/day, adjusted to trough levels). Both groups received identical targeted nursing care protocols. Outcomes compared included clinical efficacy (remission status), quality of life (IS-LQ questionnaire), incidence of adverse reactions, and recurrence rate over a 6-month follow-up. Peripheral blood CD19+ B-cell counts were monitored in the rituximab group. The study was approved by the institutional ethics committee, and informed consent was obtained.
