This is an autoimmune renal disorder chiefly involving the glomeruli with the deposition of IgA deposits in the renal mesangium. IgA is the type A antibody or immunoglobulin (Ig). This condition is normally diagnosed following an investigation of haematuria, proteinuria or an incidental abnormal renal function tests.
Is specific diagnostic evidence required to apply the SOP? – Yes.
This diagnosis is made on the basis of a renal biopsy with a pathologist providing a histological report. The relevant medical specialist would be a nephrologist.
Are there sub-factors that require specific information? – No.
Additional diagnoses covered by SOP
- Berger’s disease
- IgA nephropathy
Conditions excluded from SOP
- Nephritic syndrome – Too non-specific but this clinical picture may arise from the IgA mesangial glomerulonephritis.
- Nephrotic syndrome – Too non-specific but this clinical picture may arise from the IgA mesangial glomerulonephritis
- Glomerulonephritis – too non-specific
- Henoch-Schonlein purpura
If, after applying the above information, you are unable to confirm the diagnosis, you should then:
- seek medical officer advice about further investigation, or;
- re-encode the condition, if appropriate.
The following investigations may be useful in establishing the diagnosis.
- Report of a renal biopsy
- Medical report from a nephrologist
