Patients who develop acute nephritis where a post-infectious aetiology is not suspected should be discussed with a paediatric nephrology consultant.
In patients with a diagnosis of post-infectious nephritis, the following features should prompt discussion with a paediatric nephrologist:
- Oliguria failing to respond to adequate doses of furosemide (doses up to 5 mg/kg may be needed in presence of renal impairment).
- Persistent renal impairment
- Persistent proteinuria
- Failure of complement levels to normalize by 8 weeks
