Q

Vascular rejection needs?

A

Steroids and aggressive immunosuppressants

17
Q

ATG causes what?

A

T cell lysis

18
Q

Mtori causes less what?

A

Melanoma and Viral infection/reactivation (CMV/VZV)

19
Q

Chronic allograft nephropathy types?

What do you see in them?

A
  1. Antibody mediated rejection
    - chronic interstitial nephritis + fibrosis, vascular narrowing
  2. Immunosuppressant effect
    - Arteriolar hyalinosis + Tubular atrophy
20
Q

Post infectious GN a/w infection?

A

Streptococcus

21
Q

Autosomal recessive PCKD mutation?

A

Chromosome 6 - fibrocystin protein

22
Q

Histology of Alport syndrome and FSGS is the same - what do you see?

A

Basket weave pattern - thinning and thickening of BM

23
Q

Renal artery;
proximal/ostial part affected - what disease?
Middle to end - what disease?
Distal end - what disease?

A

Proximal/ostial - Renal artery stenosis

Middle to end - FMD

Distal end arteries - PAN

24
Q

Tuberous sclerosis mutation where?

A

Chromosome 9 - inhibit Growth hormone and mTOR signaling pathways

25
Q

What monoclonal antibody can trigger Alport syndrome?

A

Alemtuzumab CD52

26
Q

Complications of Alport syndrome?

Pathogenesis of Alport syndrome?

A

Alport can become Good pasture disease
(anti-GBM targets collagen IV)

Pathogenesis = mutation of Alpha 5 chain in Collage IV causing absence a3a4a5 chain

27
Q

Predictors of ESRF in pauci-immune pattern?

A

eGFR < 15%
Normal glomeruli percentage
Tubular atrophy/Interstitial fibrosis

15% of Normal glomeruli or Tube-In

28
Q

IgG + C3 likes to deposit in?

IgG1 likes to deposit in?

IgG3 likes to deposit in?

A

IgG + C3/ non-amyloid fibrils = Fibrillary GN - mesangial deposits

IgG1 = Immunotactoid GN - capillary wall deposits + microtubules on EM

IgG3 = membranoproliferative GN - granular deposits on EM

29
Q

Treatment of IgG4, MUSK MG disease?

A

Rituximab
