MPA Renal Risk Score at Diagnosis

Estimate end-stage renal disease (ESRD) risk at diagnosis of microscopic polyangiitis (MPA) and other ANCA-associated vasculitides using baseline serum creatinine, percentage normal glomeruli, and clinical features.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Estimate end-stage renal disease (ESRD) risk at diagnosis of microscopic polyangiitis (MPA) and other ANCA-associated vasculitides using baseline serum creatinine, percentage normal glomeruli, and clinical features

Each component has a specific meaning:

  • Baseline serum creatinine — The baseline serum creatinine recorded for the scenario being assessed.
  • Percentage normal glomeruli — The percentage normal glomeruli recorded for the scenario being assessed.
  • Clinical features — The clinical features recorded for the scenario being assessed.

Note: Interpret the mpa renal risk result against the thresholds and context described above.

How to Use

Enter the baseline serum creatinine, percentage normal glomeruli, clinical features for the scenario you are assessing. Estimate end-stage renal disease (ESRD) risk at diagnosis of microscopic polyangiitis (MPA) and other ANCA-associated vasculitides using baseline serum creatinine, percentage normal glomeruli, and clinical features. Use the mpa renal risk result to inform your calculation.
