Background
Nationwide data on the treatment of IgA nephropathy (IgAN) in Chinese patients remains unclear.Clinical Practice Optimization Initiative for Chinese Patients with IgA Nephropathy (CPO-IGAN),the first nationwide project to optimize IgAN clinical practices in China,conducted a 10-year nationwide analysis to assess adherence to evidence-based guidelines.
Methods
This retrospective study recruited biopsy-proven IgAN patients across China from January 2015,age ≥18 years with at least one follow-up after treatment initiation.Demographic factors,comorbidities,laboratory results,renal histology reports and therapeutic regimens were collected from clinical information systems.
Results
By April 2024, 2229 IgAN patients from 33 tertiary hospitals in 12 Chinese provinces had been recruited.Table 1 summarizes the clinical characteristics at the time of renal biopsy.74.3% and 5.4% of patients received RASi and SGLT2i as supportive treatment respectively.As shown in Table 2, SGLT2i use increased after the 2021 publication of the DAPA-CKD IgAN subgroup results.46.0% and 6.2% of patients recevied corticosteroids and MMF,and Figure 1 shows the characteristics of these patients.MMF use increased following the KDIGO 2021 guideline recommending it for Chinese IgAN patients.
Conclusion
Optimized treatment of IgAN in China,including the addition of SGLT2i as the new standard of care needs to be implemented. Accordingly,CPO-IGAN will conduct nationwide training to raise awareness among Chinese nephrologists.Given the high use of corticosteroids and MMF in Chinese IgAN patients,disease progression and long-term prognosis will be analyzed through further longitudinal studies by CPO-IGAN.
