概要 BACKGROUND AND HYPOTHESIS:Attribute-based medicine emphasizes tailoring care to patient-specific characteristics. IgA nephropathy (IgAN), a heterogeneous glomerular disease, presents varying risks across subgroups. We hypothesized that an attribute-based medicine approach could identify residual risk factors and inform personalized strategies.METHODS:We analysed data from 996 patients from the Japanese Nationwide Retrospective Cohort Study in IgAN. The primary outcome was kidney replacement therapy initiation or a 1.5-fold increase in serum creatinine. Six pre-specified attributes were assessed: age, sex, body mass index (BMI), chronic kidney disease (CKD) stage, urinary protein excretion (U-Prot), and urine occult blood (U-OB). Cox regression and Kaplan-Meier analyses were performed to evaluate interactions between attributes and risk factors.RESULTS:Poor kidney prognosis was associated with lower estimated glomerular filtration rate (eGFR) (per 10 mL/min/1.73 m² increase, hazard ratio [HR]=0.87), higher U-Prot (log-transformed HR=4.54), and hyperuricaemia (HR=1.64), while oral corticosteroids (HR=0.60) and tonsillectomy (HR=0.44) were protective factors. Significant interactions included the following: hyperuricaemia with BMI<22 kg/m²; hypertension with female sex; eGFR and age with CKD stage; U-Prot with age, eGFR, and corticosteroid use; and U-Prot with U-OB. Prognostic effects of age and eGFR were reversed for CKD stage 3 compared with stages 1-2. U-Prot was the most consistent predictor of poor prognosis, especially in patients with U-OB≤2+. Corticosteroids improved outcomes in patients with U-Prot≥1 g/day, while tonsillectomy was effective in those with U-OB≥3+.CONCLUSION:Attribute-based analysis revealed critical risk modifiers and supported stratified treatment strategies for IgAN. These findings underscore the potential of attribute-based medicine in guiding personalized care for patients with IgAN.
