Primary Gn Flashcards
What is the autoimmune disease characterized by circulating IgG autoantibodies against two major podocyte antigens?
PRIMARY MEMBRANOUS NEPHROPATHY (PMN)
What are the 2 major podocyte antigens in Primary MN?
- PLA2R1 (70%)
- THSDA (5-10%)
What are the 2 new classification for MPGN
- IMMUNE COMPLEX-MEDIATED
- COMPLEMENT- MEDIATED OR C3 GLOMERULOPATHY
New classification of MPGN is based on:
IF
What type of MPGN, seen in IF where both immunoglobulin and complement are deposited
Immune complex-mediated MPGN
What type of MPGN with predominant C3 staining by IF?
Complement-mediated MPGN or C3 glomerulopathy
An autoimmune disease which results from autoantibodies targeting DNAJB9 (a putative autoantigen)
FIBRILLARY GN
Patients with immunotactoid glomerulonephritis should be evaluated for the underlying 3 disorders:
- Monoclonal gammopathy
- Malignancy
- Lymphoproliferative disorders
Autoantibodies in sporadic anti-GBM disease are directed against NC1 domain of what chain of type IV collagen?
ALPHA-3 CHAIN
What antibody in ANCA-associated vasculitis, which when present lung involvement, or upper respiratory tract involvement are more likely to relapse?
ANTI-PROTEINASE-3 (PR3) ANTIBODIES
Anti-GBM alloantibodies cause posttransplantation nephritis in X-linked Alport syndrome are directed against the NC1 domain of what chain of the type IV collagen?
ALPHA-5 CHAIN
IgA vasculitis was previously called as?
HENOCH-SCHONLEIN PURPURA
GPA (Granulomatosis with polyangiitis) was previously called?
WEGENER’S GRANULOMATOSIS
EGPA (Eosinophilic granulomatosis with polyangiitis) was previously called as?
