- Brief Summary
This study investigated the combined impact of rituximab and targeted nursing care versus tacrolimus and targeted nursing care on efficacy, quality of life, adverse reactions, and recurrence rate in children with challenging (steroid-dependent or frequently relapsing) nephrotic syndrome. Ninety-one pediatric patients were randomized to either receive rituximab plus targeted nursing or tacrolimus plus targeted nursing, and outcomes were assessed over a 6-month period.
- Detailed Description
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.

- Informed consent obtained from the guardians and assent from children capable of understanding.
- Steroid-resistant nephrotic syndrome (SRNS).
- Severe renal insufficiency (according to KDIGO criteria or other relevant standards).
- Cognitive or mental disorders.
- Worsening condition upon admission necessitating intensive care.
- Parents unable to provide long-term care or unwilling to participate.
- Interruption of hospitalization for any reason.
- Prior treatment with rituximab or tacrolimus.

Tacrolimus with Targeted Nursing Care Baseline Glucocorticoid Therapy Patients received oral tacrolimus capsules in conjunction with baseline glucocorticoid therapy and a standardized targeted nursing care program identical to the study group.

- Primary Outcome Measures
Name Time Method Total Effective Rate At 6 months post-treatment initiation. The percentage of participants who achieved a "Significantly effective" or "Effective" response. Efficacy is defined based on remission status, renal function, and proteinuria levels. Total effective rate is calculated as the number of (Significantly effective + Effective) cases divided by the total number of cases in the group.
Recurrence Rate Within the 6-month follow-up period after treatment initiation. Relapse defined as urinary protein ≥2+ or urinary protein quantity \>50 mg/kg (or urine protein/creatinine ratio \>2.0 mg/mg), occurring on three consecutive days within a 7-day period, after having achieved remission.
- Secondary Outcome Measures
Name Time Method Change in Quality of Life as Assessed by the Children's Subjective Quality of Life Questionnaire (IS-LQ) Baseline and at 6 months post-treatment initiation. The IS-LQ consists of 60 items, scored from 1 to 4, with higher scores indicating better quality of life. Assesses six areas including cognitive, emotional, and overall functioning.
Adverse Reactions During the 6-month study period. Any adverse reactions recorded, including infections, infusion reactions (for rituximab), hypertension, hyperglycemia, electrolyte disturbances, and gastrointestinal symptoms.
