Overview
Rapid diagnosis of rapidly progressive glomerulonephritis is very crucial to save kidneys function
Diagnostic study of choice:
Renal biopsy:
- Renal biopsy will provide the most accurate reslt.
- Renal biopsy will give accurate information about the extent of the disease and therapy can be planned accordingly.
results of Renal biopsy:
- Light microscopy reveals
- Diffuse inflammation in glomeruli with rupture and damage to glomerular basement membrane.
- Crescents are present in the Bowmans space.
- Renal vessels can show transmural vasculitis, with necrosis and lymphocyte infiltrates.
- Tubular necrosis may also be present.
- Interstitial granulomas in the glomeruli indicate Wegener’s granulomatosis.
Immunoflourescence
- In type I RPGN- diffuse and linear deposition of IgG along the GBM.
- In ttype II RPGN- diffuse and irregular deposition of IgG and C3 in the mesangial matrix.
- In type III RPGN- no finding.
- Electron microscopy
- In type I and type III, no electron dense deposits are seen.
- In type II RPGN, subepithelial electron dense deposits indiacting the presence of immune complexes are seen.
Serologic studies
- Complete blood cell count (CBC) withdifferential,
- Anemia can be seen in patienst with renal failure or gastrointestinal tract bleeding.
- Eosinophilia greater than 13% suggest Churg-Strauss disease.
- Serum electrolytes
- BUN(blood urea nitrogen)
- Serum creatinine
- Lactate dehydrogenase (LDH)
- Creatine phosphokinase (CPK),
- The most common abnormality is an increased serum creatinine level
- Urinalysis with microscopy: Proteinuria equal to or greater than 2-3 g in 24 hours.
- Microscopic hematuria
- Red cell casts indicates glomerular inflammation
- Erythrocyte sedimentation, elevated with active disease.
- C-reactive protein: levels are elevated and correspond with disease activity.
- Antinuclear antibody (ANA).High ANA titer is present in systemic lupus erythematosus.
