The term „glomerulonephritis” may refer to
• Etiology: poststreptococcal GN (PSGN)
• Serological abnormality: ANCA-associated GN
• Light microscopic findings: Membranoproliferative GN (MPGN),
mesangial proliferativa GN
• Immunfluorescent findings: IgA nephropathy (IgAN)
• Clinical syndrome: nephritic syndrome, rapidly progressive GN
(RPGN)
• Systemic disease: Lupus nephritis (LN)

Overview
• Classification of GN
• Diagnosis of GN
• Some examples
![Page 4: Otthoni vérnyomásmérés tapasztalatai](https://reader034.vdocuments.mx/reader034/viewer/2022050504/6271925f4119cf5c2a260e78/html5/thumbnails/4.jpg)
Glomerular disease may be classified according to:
• Clinical syndromes (clinical presentation)
– Nephritic syndrome
– Nephrotic syndrome
– RPGN
– Isolated proteinuria/ hematuria
– Acute kidney injury
• Primary renal disease or renal manifestation of a systemic disease (secondary)
• Renal biopsy histology, proliferative or non-proliferative
– These are the different pathological types
![Page 5: Otthoni vérnyomásmérés tapasztalatai](https://reader034.vdocuments.mx/reader034/viewer/2022050504/6271925f4119cf5c2a260e78/html5/thumbnails/5.jpg)
Immune mechanisms in glomerular diseases
• Antibody against a local antigen
– Podocyte antigen (membranous GN: phospolipase A2
receptor)
– Glomerular basement membrane antigen (Goodpasture’s)
• Deposition of circulating immune complexes with
inflammation
– E.g. IgA nephropathy, cryoglobuliemia, SLE
• Without immune complexes („pauci immun”), but with
immune mechanism
– ANCA associated diseases

activating antybody against C3 convertase (C3 nephritgen
factor faktor) or other mechanisms (C4 is norm)

• Clinical picture:
– male:female 2:1
– Typical presentation micro or macroscopichematuria (+/- proteinuria)
– Sometimes nephritic syndrome
– Higher IgA level
– If accompanied by systemic signs (vasculitis) than it is Henoch-Schönlein purpura
• Pathogenesis
– Galactose deficient IgA production
– Autoentibodies against these IgAs
– Immun complex deposition in the mesangium
• Renal biopsy
– Mesangial proliferation
– Mesangial IgA deposition
![Page 42: Otthoni vérnyomásmérés tapasztalatai](https://reader034.vdocuments.mx/reader034/viewer/2022050504/6271925f4119cf5c2a260e78/html5/thumbnails/42.jpg)

Goodpasture’s syndrome
• Rare disease: 1/1million/year
• Pathogenesis
– Antibody formation against the „non-collagenous” region
of alpha 3 chain of type IV collagen found in the
glomerulus and lung. This causes inflammation and
proliferation
– Pulmonary manifestation frequently after infection, or
other pulmonary damage
– In Alport syndrome after transplantation

Renal manifestations in SLE
• WHO type I: no renal change
• WHO type II: mesangial proliferative GN
• WHO type III: focal proliferative GN
• WHO type IV: diffuse proliferative GN
• WHO type V: membranous GN
• WHO type VI: chronic renal failure
• Types II-V may be associated with crescent formation and
necrosis indicating poor prognosis and necessitating agressive
immunosuppression
• Rx:
– Steroid i.v. p.o. tapering, cyclophosphamide i.v. 500mg q2weeksx6
