• Post-streptococcal glomerulonephritis – Would usually be associated with history of group A streptococcal infection rather than viral infection.
• Staphylococcus-associated glomerulonephritis – Would usually be associated with staphylococcus infection rather than viral infection.
• Thin basement membrane nephropathy – Usually associated with family history.
• C3 glomerulopathy – Associated with elevated C3 levels.
• Hemolytic uremic syndrome – Often presents with bacterial gastrointestinal tract infection and diarrhea.
• Alport syndrome – Presents with hematuria, sensorineural hearing loss, vision problems, and family history.
• Goodpasture disease (anti-glomerular basement membrane antibody disease) – Presents with hemoptysis.
• Granulomatosis with polyangiitis (Wegener granulomatosis) – Presents with chronic sinusitis and cough, c-ANCA associated, patients in remission may develop IgA nephropathy.
• Microscopic polyangiitis – Presents with purpura and cough, p-ANCA associated.
• Eosinophilic granulomatosis with polyangiitis (formerly Churg-Strauss syndrome) – Presents with asthma and sinusitis, p-ANCA associated.
