About this study
This was a retrospective study. Children who were diagnosed with refractory nephrotic syndrome and treated with rituximab (RTX) and followed up for ≥1 year in the Department of Pediatrics, the First Affiliated Hospital of Xiamen University from March 2020 to March 2026 were enrolled. Personal information, past medical history, clinical examination data and follow-up data before and after the use of RTX were extracted from the medical record system. (1) The median relapse-free survival, the number of relapses and the adverse reactions of RTX were compared before and after RTX treatment, and the clinical efficacy and safety of RTX were evaluated. (2) By comparing the annual relapse frequency, reduction and withdrawal of steroids and immunosuppressive agents, B cell reconstitution and adverse drug reactions between prophylactic RTX and post-relapse RTX maintenance regimens; (3) Multivariate analysis of risk factors for recurrence of nephropathy after RTX treatment. (4) growth indicators monitoring patient evaluation and RTX medical economic benefit analysis.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
RituximabDrug
B lymphocyte reconstitution was performed regularly after the administration of rituximab, and 1-4 doses of rituximab were given according to the exhaustion of B cells in children.
| Study group | Role | What they receive |
|---|---|---|
| Sequential prevention group | According to the situation of B cells to rebuild the preventive use of rituxan, each 375 mg/m2. Receives: Drug: Rituximab | |
| Recurrent sequential group | In patients with recurrence after the use of rituxan, each 375 mg/m2. Receives: Drug: Rituximab |
What is being measured
The primary outcome is the main question the study is designed to answer.
The median relapse-free survival
The median relapse-free survival of nephrotic syndrome before and after RTX treatment was compared.
Measured: 1 year
Different sequential group curative effect evaluation
After comparing the preventive RTX and recurrence RTX maintain annual recurrent treatment。
Measured: 1 year
Secondary outcomes (1)
Risk factors for renal disease recurrence after RTX treatment.
Multivariate cox analysis was used to analyze the risk factors of relapse after rituximab treatment in children with nephrotic syndrome by including gender, age of onset of nephrotic syndrome, course of disease before rituximab, history of immunosuppressive therapy, age of rituximab treatment, and maintenance immunosuppressive therapy after rituximab.
Measured: 1 year
