- Lead Sponsor
- Wang Mo
- Brief Summary
Clinical information of children with ANCA-associated nephritis admitted to Children's Hospital Affiliated to Chongqing Medical University and partner centers from January 1, 2023 to December 31, 2023 was collected:
To evaluate and compare the differences in survival, renal outcomes, and adverse reactions in children with ANCA-associated nephritis given different interventions according to the revised PARRG risk stratification, and to evaluate the superiority of ANCA-associated nephritis given according to the revised PARRG risk stratification.
(2) To evaluate the efficacy and safety of glucocorticoid combined with rituximab and cyclophosphamide as induction regimen in high-risk group and glucocorticoid combined with rituximab as induction regimen in children with ANCA-associated nephritis (AAGN) in low and middle risk group based on PARRG risk stratification

Group Intervention Description Control group-Low and medium risk group GlucoCorticoid The children with AAGN admitted to all cooperating units during 2017.01.01 to 2022.12.31 were followed up for more than 6 months, and the case data were complete. PARRG Classification (pediatric AAGN renal risk grade, pediatric AAV renal risk grade, PARRG) According to the PARRG grading method provided by the Affiliated Children's Hospital of Chongqing Medical University, the enrolled children with AAGN were classified into high risk group, medium risk group, low risk group, medium risk group, low risk combination and low risk group according to the two indexes of eGFR and percentage of glomerular sclerosis during renal biopsy. PARRG risk grading criteria: There are two risk factors for ESRD: (1) eGFR≤20ml/min/1.73m2 at renal biopsy; ② The proportion of glomerular sclerosis ≥30%; High risk resistance: meet 2 risk factors; Moderate risk group: only 1 risk factor; Low risk group: no above risk factors; Control group-High risk group GlucoCorticoid The children with AAGN admitted to all cooperating units during 2017.01.01 to 2022.12.31 were followed up for more than 6 months, and the case data were complete.

All children with AAGN were PARRG risk graded before treatment with RTX and CTX: PARRG Classification (pediatric AAGN renal risk grade, pediatric AAV renal risk grade, PARRG) According to the PARRG grading method provided by the Affiliated Children's Hospital of Chongqing Medical University, the enrolled children with AAGN were classified into high risk group, medium risk group, low risk group, medium risk group, low risk combination and low risk group according to the two indexes of eGFR and percentage of glomerular sclerosis during renal biopsy.

- Primary Outcome Measures
Name Time Method Response rate (complete and partial response rate) 6 months The rate of complete or partial response to ANCA vasculitis-associated nephritis (AAGN) was assessed at 6 months. Complete AAGN response was defined as: 1. Estimated glomerular filtration rate (eGFR) ≥60ml/min/1.73m2, or a decrease of less than 15% from baseline eGFR; 2. Proteinuria ≤0.3g/24 hours.Partial AAGN response was defined as: 1. Estimated glomerular filtration rate (eGFR) ≥30ml/min/1.73m2, or a reduction of less than 50% from baseline eGFR; 2. Decreased proteinuria\>Baseline 50% or 24-hour urinary protein quantification\<50mg/Kg.d.
