Diagnostic Considerations
The following 4 renal syndromes commonly mimic the early stage of acute glomerulonephritis (GN):
- Anaphylactoid purpura with nephritis
- Chronic GN with an acute exacerbation
- Idiopathic hematuria
- Familial nephritis
Postinfectious GN must be differentiated from the following conditions:
- Immunoglobulin A (IgA) nephritis - The latent period between infection and onset of nephritis is 1-2 days; alternatively, nephritis may be concomitant with upper respiratory tract infection (ie, “synpharyngitic nephritis,” in contrast to the “postpharyngitic nephritis” seen in poststreptococcal GN [PSGN], which occurs 1-3 weeks later).
- Membranoproliferative GN (MPGN), types I and II - This is a chronic disease, but it can manifest with an acute nephritic picture with hypocomplementemia; failure of acute nephritis to resolve should prompt consideration of this possibility.
- Lupus nephritis - Gross hematuria is unusual in lupus nephritis.
- GN of chronic infection - This can manifest as acute nephritis. Unlike PSGN, in which the infection may have resolved by the time nephritis occurs, patients with nephritis of chronic infection have an active infection at the time nephritis becomes evident. Circulating immune complexes play an important role in the pathogenesis of acute GN in these diseases.
- Vasculitis - Nephritis of methicillin-resistant S aureus (MRSA) may be associated with vasculitic lesions of the lower extremities.
- Predominantly nonglomerular diseases - Thrombotic thrombocytopenic purpura (TTP), hemolytic-uremic syndrome (HUS), atheroembolic renal disease, and acute hypersensitivity interstitial nephritis may present with features of acute nephritic syndrome and should be differentiated.

Other problems to be considered include the following:
- Bacterial, viral, and fungal etiologies
- Chronic GN
- Idiopathic hematuria
- IgA nephropathy
- Irradiation of Wilms tumor
- Trauma
