Case definition of immune-complex glomerulopathy not otherwise specified (ICG-NOS) subgroups
| ICG-NOS group | Definitiona | Number of patients |
|---|---|---|
| Full-house (ICG-FH) | +IgG/+IgM/+IgA/+C3/+C1q | 3 |
| Quasi-full-house (ICG-qFH) | +IgG/+C3/+C1qb | 10 |
| IgA-rich (ICG-IgA) | IgA (co-)-dominantc | 3 |
| C1q-rich (ICG-C1q+) | −IgG/+C1q | 6 |
| C1q-poor (ICG-C1q−) | +IgG/−C1q | 6 |
FH, full-house; qFH, quasi-full-house.
a
+ means at least trace staining for that Ig.
b
Can also be +IgM or +IgA, but not both.
c
Does not meet criteria for typical IgA nephropathy (Supplementary Table S1).
