Table 1 compares the demographic, clinical, laboratory findings at diagnosis and initial treatment modalities of patients with IC-MPGN to those with C3GN. The median age of patients with IC-MPGN and with C3GN was 62 and 19 years, respectively. Patients with IC-MPGN had a significantly higher systolic and diastolic blood pressure (140/76 vs. 113/65 mmHg), proteinuria values (3.89 vs. 0.77 g/day), worse renal function (sCr, 1.16 vs. 0.65 mg/dL; eGFR, 53.0 vs. 99.3 mL/min/1.73 m2), and lower serum albumin (2.9 vs. 3.7 g/dL) when compared to those with C3GN. This evidence concerns the gene ALB and primary membranoproliferative glomerulonephritis.
